Summary

Drum Anchor Winch for Sale
Drum Anchor Winch for Sale

The endless rope conveyor winch is a kind of mine auxiliary transportation equipment. It uses wire rope to work round and round to realize the transportation function of the underground working equipment. Because of its advantages of convenient installation, simple operation, low investment, low cost, long transportation distance and continuity of transportation, it plays a very important role in the coal mine production as the main transport or auxiliary transportation equipment. However, most of the Endless Rope Winches used in coal mines are still at the level of the 50s and 60s, with small traction, simple functions, small power and low efficiency. Although some coal mines have carried out technical transformation, they still can not meet the needs of current mine development and production. In this case, a new type of endless rope winch is designed.

China Cheap AQ-JMM Electric Rope Winch for Sale
China Cheap AQ-JMM Electric Rope Winch for Sale

The endless rope conveyor winch structure is composed of motor, coupling, electro-hydraulic brake, transmission, manual brake, roller device, and base. The base is welded by the channel steel. The motor, transmission and drum device are fixed on the base by bolts. The brake steel belt of the 2 manual brake is respectively held with the brake wheel and the internal gear, and the brake handle and the brake block are welded to the base. When working, the motor passes the power to the transmission through the coupling, and the output gear of the transmission meshes with the big gear ring on the drum to drive the operation of the drum.

Top Five Characteristics

The rope winch has the following structural features:

(1) the overall layout is reasonable, the structure is novel and compact, the volume is small, the occupied area is few, and the power input direction is perpendicular to the roller shaft. It can realize two-way operation, continuous transportation, long-distance transportation and high efficiency.

(2) the winch uses a new type of transmission, which is ingenious. The transmission has double functions of deceleration and braking, the structure is basically symmetrical, the appearance is beautiful and generous, the layout of internal parts is reasonable and the structure is tight. The output of the gear transmission is different from that of the previous axle output. Thus, a connecting device to a transmission output shaft and a roller shaft can be reduced, and the transmission link can be reduced. The gear meshing transmission is adopted, and the transmission efficiency is high. It is a new type of reducer with high efficiency, large speed ratio and large load capacity.

(3) increased manual braking function and its safety and reliability have also been greatly improved. The braking device is arranged in the intermediate link of the transmission. The speed of the inner gear of the brake wheel and the planetary transmission is relatively high. Compared with the brake wheel and the drum, the required braking force is greatly reduced. The specific reduction is related to the transmission ratio of the last gear meshing, and the diameter of the brake wheel is also changed. Small。 In this way, the braking function can be realized with smaller braking force, and the operation safety and reliability can be enhanced. At the same time, due to the smaller braking force, the brake belt also has a smaller force, less wear and longer service life. The brake handle device is located at the tail part of the winch, and the operation is simple and convenient.

(4) the structure of the roller is symmetrical, supported by a pair of self-aligning roller bearings on the roller shaft, supporting effect is good, supporting rigidity is high, and the operation is stable. And the spindle is the axis of the heart, does not bear the dynamic load so that the strength and stiffness of the shaft demand are greatly reduced, so it can reduce the process link, save material, reduce cost.

Winch Operation Noise Reduction Methods

20 ton winch for sale

Causes and control methods of hoist noise

Construction hoist GB1955-2002 national standard GB 1955-2002 qualified winch noise limits outside the machine are not greater than 85dB (A), the operator cannot be greater than the ear 88dB (A). When the hoist traction is small, the speed is low, the noise is far below the standard limits, the control is also easy; but when the traction speed is high, to ensure that the traction is not excessive noise, from the design, technology, materials, quality Inspection and other links to take effective measures.

Existing  problems

There are many ways to get the noise of hoist, but in essence, it is the result of impact and vibration, which is usually caused by the poor gear meshing quality and unstable motion.

Chassis

We believe that the chassis design and manufacture are caused by noise may be: the chassis adopts box type structure, not all welds are continuous welding, the weld length, different chassis height, there exist great individual differences in chassis rigidity, others resonate effect, machines such as a little vibration noise is amplified; the chassis is made of steel plate welding, do not have the shock absorption, noise elimination function, if close to the natural frequency and the meshing frequency may cause the individual machine for small gear vibration caused greater total shock caused by noise value rise.
we in view of the above possibilities are tested, but by three experiments showed weak correlation factors of noise level and chassis structure, stiffness, frequency, noise and moving parts strongly correlated, so the chassis structural design, manufacturing quality and not exceed the standard noise causes.

Single Drum Piling Winch for Sale

Bearing clearance

It is believed that since the noise is accompanied by a drum assembly and a transmission, it may be caused by the large clearance of the roller bearing. We choose the clearance of the reel parts to ensure that the clearance between the bearing hole and the spindle is in accordance with the requirements of the drawing, and the test is carried out after the assembly is assembled. Frequency conversion motor is used in the test to observe the influence of speed on noise.
A large number of test results show that the influence of speed on noise is the first. The higher the speed of the drum, the greater the noise and the more intense the machine vibration. Secondly, the larger the gap between spindle and bushing, the greater the noise. The chassis has the least influence on noise. If the machine noise is very low, the speed and the size of the spindle gap will not generate excessive noise, which indicates that the excessive noise is not caused by the large bearing clearance.

Gear quality

After the inspection of gear common normal length tolerances, the base tangent length of radial gear tolerance, runout, drum related coaxially and the spindle shaft neck beating control indicators are within the scope of the standard specification, but on further examination found to exceed the standard gear tooth profile error, the reason is hob grinding. Because it is a large modulus cutter, cut and processed materials, roll cutting resistance of cutting-edge, easy blunt, with a number of parts processing midway may need one or two knives grinding, such as grinding rake hob tooth profile control is not good, easy to deformation, while the processing is no longer the standard involute tooth profile and the instantaneous acceleration produces motion, motion instability will inevitably generate vibration and noise.
winch as a general precision products, in the implementation of new standards for gear accuracy did not paid much attention to the inspection of tooth profile error, many units which are not indicators of detection equipment, so even if the drawings made this request in the actual test operation is not very good, although the length of normal line, change tolerance and ring gear jump targets to meet the requirements, but the gear is still unqualified.

Winch Factory shall always provide useful information about hoist winch for clients. During the winch operation, usage, purchasing you may meet different kinds of problems, right here we are helping you out from these troubles.

The relationship between winch lubrication and the working life of winches

Improve working conditions of hoist gear tension and poor, high speed and heavy load are directly caused by the failure of the gear surface damage, and through proper lubrication materials and lubrication, to ensure the winch gear get sound lubrication, protect the gear, and prolong the service life of the winch.
For the winch, the correct and timely lubrication is very important, because the relatively sliding surface, under the action of pressure, if it is in dry friction state, it will be damaged in a short time.Good lubrication can absorb the impact and vibration produced by winch gear transmission, reduce the noise of gear, prevent scuffing tooth surface, reduce the wear of tooth surface, and improve the bearing capacity of the tooth surface.However, in the winch users, many do not understand the important role of winch lubrication and winch users have not paid enough attention to the hoist windlasses lubrication, and they always use winch lubrication oil casually, which does not meet the user requirements.In the field of handling the winch fault, there are many faults caused by poor lubrication.

Cautions for Temporary Installation of Windlass Manufactured by Winch Factory

  • The installation of the windlass in the construction is mostly temporary installation, using the reserved holes on the machine frame or fixing the anchor on the ground anchor with the wire rope coiling machine frame.The rear part of the winch machine is equipped with pressing iron to ensure that the hoist does not slide, displacement and overturn during the operation.
