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.

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.

Tensioning device

  • The tensioner should be firmly and stably installed on the cement foundation, and the upper part can be fixed and fastened with the ring chain and the top side to withstand the unexpected lateral force.
  • The direction of the guide wheel at both ends should be consistent with the direction of the wire rope.
  • In operation, it is necessary to pay attention to whether the pulley and weight can move up and down freely, and there must be no stagnation.

Shuttle car

  • Two wedges must be checked for a fixed wire rope before each operation and should be fastened immediately if there is a loosening.
  • After the wire rope is taken and placed, the positioning pin should be inserted into the hole of the rope cylinder to prevent the rope from escaping in operation.

Safety precautions for winch use

china hand winch for sale
china hand winch for sale

  • Pedestrians (except with the driver) are prohibited when the vehicle runs, with a sound and light warning, a warning network at both ends, and a strictly prohibited person from entering.The winch is not allowed to carry the personnel, and the hooked head is strictly prohibited.
  • The point of the endless rope winch is: a little parking, two positive running points, three reverse operations, and the winch is strictly prohibited.
  • The endless rope winch is only allowed to hang the vehicle after the shuttle bus, and the vehicle is strictly prohibited in front and rear of the shuttle car.The number of strung vehicles depends on the traction capacity of the winch, and no more than 3 vehicles are not allowed to Trailer each time.When transporting overweight, super high, super long equipment and large pieces, only one must be pulled at one time.With three ring chain, connected with the shuttle car insurance pin must all transport objects of the vehicle, the other end with a shackle, rope and wire rope clips are firmly connected with.
  • The car driver should always pay attention to the normal track in front of the vehicle in the course of the vehicle, and there is no matter that affects the running of the vehicle on the track.The signal transmitter should be carried with you.

   Operation procedures and precautions in the process of starting and running:

After determining the driving condition with the driver, send the driving signal again, and send the signal no less than 2 times. After the winch driver receives the second signal, it starts the car again.The driver and the winch driver must memorize the use of the signal.In the course of operation, the driver should pay attention to the normal operation of the vehicle, and the winch driver should pay attention to the normal work of the endless rope winch and the Zhang Jin device.

  • When the windless winch is running, the driver should be equipped with two divulging mobile phones, a normal user and a spare.
  • No pole rope winch in operation, shuttle car in the upper, downhill yard, 30m in front of the tensioner, 30m in the vicinity of the tail wheel, and the tunnel turn.
  • The operator should regularly check the tightness of the wire rope and keep enough tension of the wire rope. If we need to tighten the rope, fix the wire rope and a rope head, and tighten the wire rope with 5 tons of gourd, we must tighten the wire rope on the shuttle car when the required tightening force is reached.
  • The brake device of the endless rope winch should be checked regularly to ensure its sensitivity, safety, and reliability, otherwise, it should be handled in time.
  • When the heavy vehicle falls off the road, the winch brake lock should be combined and stable first, and the road vehicle will be restricted reliably, and then the road vehicle is processed according to the regulations.
  • When the shuttle vehicle is reset, it is necessary to use the gourd to pull the same direction of the shuttle bus to prevent the retracting of the wire rope when the vehicle is on the road.
  • In order to prevent the vehicle in the middle of endless rope off the road, when necessary, in the special area to avoid wind chamber setting signal, operation condition and arrange personnel to monitor vehicles, find the problem promptly issued a stop signal.
  • Regularly inspect the wear condition of steel wire rope and find out the problem is dealt with or replaced in time. The wire rope head must be inserted. The length of inserting wire rope is not less than 1000 times of the diameter of wire rope.
