Right here in this post,Winch Factory will share some safety operation rules of a winch with winch operators which include the following items:
Winch Closing Work
Winch Operator Shift System
Inclined Lane Transportation Management System
Post Responsibility System for Car Drivers
Operation Rules for Drawworks/Winches Drivers
The winch driver must be trained and certificated after obtaining the certificate of examination. The winch driver should strictly comply with the operating procedures and the relevant provisions of coal mine safety regulations.
When operating the winch machine, the operator should be centered on its work duty and not permitted to drink, and wear clothes met safety requirement.
Preparations Should Make before Winch Operation
The driver should be familiar with all kinds of signals, the operation must be strictly according to the signal execution, the signal is not clear, not allowed to start winch.
When starting, it must be lifted slowly. After moving for a distance, the hoisting speed should be normal according to the rated running speed.
When lifting winch driver cannot leave the handle and the brake handbrake, also concentrates, observe, operating conditions, such as the current sound winch, winch rope is running or beating abnormally found abnormal immediately stop the winch operation, someone to view or process, can work normally.When lifting winch driver cannot leave the handle and the brake handbrake, also concentrates, observe, operating conditions, such as the current sound winch, winch rope is running or beating abnormally found abnormal immediately stop the winch operation, someone to view or process, can work normally.
In the process of lowering, must leave
work, prohibit setting off the car.
The speed must be slowed down when the yard is expected to enter.
No overload operation, mine inclined shaft hoisting jump Road, ban rerailing winch traction.
It is strictly prohibited to adjust the brake at the same time, prohibited the operation handle and brake hand brake and brake.
Rules Should Follow During Winch Operation
The wire rope is checked according to the test point every 30 meters.
Winch Closing Work
When lifting winch driver cannot leave the handle and the brake handbrake, also concentrates, observe, operating conditions, such as the current sound winch, winch rope is running or beating abnormally found abnormal immediately stop the winch operation, someone to view or process, can work normally.
The wire rope must be replaced if it is damaged by a section of the tensile force or its length is increased by more than 0.5%.
The number of broken wires or elongation at the end of the rope is suddenly accelerated (for example, a significant elongation for three consecutive days or a broken wire occurs in a certain twist pitch every day, it must be replaced immediately).
The wire rope must be replaced because of the above signs, such as the rope head and the other parts of the wire rope failed to meet the requirements of daily inspection, it is allowed to use the method of cutting rope head.
Winch Operator Shift System
The two sides of the transfer must be handed over on the job site according to the prescribed time.
The shift must be on duty and to make clear the successor, who can handle the problem by the shift, not handle, to timely reporting, and record.
The equipment, materials, tools, equipment, spare parts and accessories should be handed over clearly.
The two parties should conduct a round trip inspection according to the normal inspection route and project, find out the problem, fill in the shift record in time and report to the leader in order to get the treatment as soon as possible.
Both sides should operate winch once to two times, experience winch operation, confirm the error, before the formal handover.
If the successor considers that some important security issues have not been clearly explained, he can refuse to take over, but he must timely report the decision of the captain on duty, and the successor shall not refuse to take over the case without cause.
Do not give any handover certificate or drunk, the spirit is not normal, nonduty winch operators didn’t explain the succession.
Unable to take over the succession, the shift cannot leave positions, should be reported to the leadership, and agreed to deal with, can leave work.
The two sides believe that after the handover is clear, should be completed in the handover record, the two sides signed valid.
Inclined Lane Transportation Management System
No road car-pedestrian winch and oblique lane transport hook are prohibited.
The hook workers should strictly implement the operation rules of the hook, strictly forbid to pull, push and jump.
Oblique lane transport must install and use the retarder and barrier, must set up and use the signal swing yard.
The inclined lane must be checked by rail transit every day, and the problems should be dealt with in time.
The hoisting device for inclined roadway transportation must be equipped with the following safety devices and meet the technical requirements:
The wire rope for hoisting and hoisting in inclined roadways must meet the following requirements:
Before the new rope is used, each wire rope must be tested for breaking, bending and torsion, and the unqualified steel rope is forbidden to use.
The steel rope in use is tested every 6 months since its use, and its safety factor shall not be less than 7.
The use of wire rope wear, broken wire, and other circumstances, must be in accordance with the relevant provisions of the coal mine safety regulations.
The car parked in the car, prohibit the winch on the road car off the road on the winch handle on the road picking head is prohibited from.
The connecting device of the up and down guide rope and the fixed pillar used by the winch must be firm and reliable, and the personnel must inspect the guide rope wheel, the fixed support, and the steel wire rope before the winch is used, and the problems should be dealt with seriously, otherwise, the operation is not allowed.
Use the winch on the mountain, must be in the car with a car arrester, and flexible work, get off the field must have to escape the cave, the acousto-optic signal range, sensitivity.
Safety Operation Procedure for Windlasses with Hook
The hook worker is qualified by the training examination, and the hook is forbidden using without any license.
Before the operating, please check signal, switch, lighting, parking hook and 15 meters of wire rope whether they are in a normal state.
When the trailer is concerned, pay attention to check whether the connection device of the mine car’s seat is good and whether the vehicles are connected reliably.
Check the materials, equipment, timber car binding is strong, long and wide and high compliance between two adjacent vehicle distance must be maintained between 250 – 400mm, if not beyond the scope of the trailer.
It is prohibited to use other goods instead of a three-ring chain and connecting rod, and the rope sleeve connected with steel wire sleeve must be carried out according to the relevant regulations, otherwise, it is not allowed to use.
The chain should stand on the side of the car, not the head or other parts of the body into the empty car, are not allowed to hang “flying chain”.
Trailers and cranes must be in accordance with the specified quantity.
To start the slow signal, when the vehicle into the Lane Lane trunk, you can send a quick signal, the hook is not allowed to pedal car.
The safety facilities on the winch lane should be kept in good condition and reliable and should be used normally.
Transporting Explosives and detonators is strictly prohibited.
The faulty tramcar must be discontinued.
To hook the chain, must stand in the place of safety operation, prevent the car knocked down or steel bullet wound personnel accident.
The RBI signal must be clear and accurate, and the road drop must be connected to the winch driver.
When the work is finished, the hook head should be removed from the mine car and placed in the middle of the track, and it is not allowed to be placed on the track surface.
Post Responsibility System of Winch Driver
Winch driver must hold “post qualification certificate” and “special operation personnel qualification certificate” to be able to post, otherwise, no operation winch.
Stick to their posts, shall not be absent from duty to the unit responsible for the safety of equipment and ensure the safe operation of the mine hoist.
Adhere to the principle of the coal mine production safety, establish the idea of “safety first, focus on careful operation in the winch operation, not to talk with others, slapstick, the operation should not handle, is strictly prohibited in the equipment stops when you replace the winch driver.
Personnel should be familiar with their own business, study technology, do “three know four”: know the structure of the equipment principle, know the technical performance, know the role of safety devices; will operate, maintenance, maintenance, will eliminate some common faults.
The winch driver must see and hear the signal before it can start or stop the winch. For the abnormal signal or fault found in the winch operation, it must stop immediately, find out the reason, and then continue driving after troubleshooting.
With the maintenance of maintenance, maintenance should be carried out during the operation system, adhere to one person operation, one person custody, and maintenance after the commissioning and acceptance.When the winch emergency stop, must be accurate and detailed to the electromechanical staff report, the reason is not identified, without permission, no return to power drive.
Strict implementation of “pedestrians do not drive, not driving” regulations.
Fill in “five records” carefully: shift record, tour record, safety device test record, personnel entry and exit record, operation log.Be responsible for ventilation, cooling and fire prevention of computer room and equipment, and maintain equipment and environmental sanitation.Be responsible for ventilation, cooling and fire prevention of computer room and equipment, and maintain equipment and environmental sanitation.
