Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric winch technology, specifically a noise-reducing electric winch. Background Technology
[0002] An electric winch consists of an engine, transmission device, drum, operating mechanism, and base frame. It is a forest harvesting and transportation machine that uses a drum to wind a steel wire rope to lift or pull loads (timber). According to its application, it can be divided into two types: cableway winches and loading winches. It is mainly used as the power source for aerial cableways and other timber collection and transportation equipment in forest areas, for loading, unloading, and stacking logs or timber in timber yards and mountain log yards. With slight modifications, the winch can also be used as the power source for other forestry lifting and conveying equipment such as pushing timber across rivers, unloading timber stacks, and sorting timber.
[0003] Existing electric winches generate noise during operation due to friction as the traction rope winds around the take-up roller. Furthermore, the traction rope is prone to breakage after prolonged use. Additionally, the motor inside the winch also produces noise during operation. Moreover, the take-up roller, pulled by the traction rope, rubs against the winch housing at its connection point with the motor and gearbox, generating further noise. In summary, existing electric winches pose a noise pollution problem. Utility Model Content

[0017] Preferably, the control box is equipped with a partition, which forms a control area and a liquid storage chamber. The spray head consists of a buffer and a nozzle.
[0018] By adopting the above technical solution, the buffer component on the spray head can prevent the spray head from being damaged by high-pressure lubricating fluid.

A winding roller 13 is rotatably mounted between the body 6 and the second protective shell 11. Through the cooperation between the liquid storage chamber 2, the spray head 3 and the booster pump 5, the lubricating fluid in the liquid storage chamber 2 is extracted and sprayed out from the spray head 3, so that the lubricating fluid can be sprayed on the traction rope. This reduces the coefficient of friction between the traction ropes during the winding process, reduces the noise generated by the traction ropes due to mutual friction, and also reduces the probability of the traction rope breaking due to friction. In addition, a cavity 10 is provided on the first protective shell 6, and the cavity 10 is filled with lubricating fluid to lubricate the connection between the output end of the motor 7 and the winding roller 13. All these components work together to reduce the noise of the electric winch.
[0030] In this embodiment, a gearbox 12 is provided inside the second protective housing 11. The output end of the motor 7 and the gearbox 12 are respectively connected to both sides of the take-up roller 13. Through the cooperation between the motor 7 and the gearbox 12, the take-up roller 13 can rotate smoothly, and the gearbox 12 can also adjust the speed of the take-up roller 13.
[0031] In this embodiment, a connection port is provided at the middle position of the first protective housing 6 and the second protective housing 11 near the control box 1. A first bearing 14 is provided inside the connection port of the first protective housing 6 and the second protective housing 11.
[0032] In this embodiment, a second bearing 15 is provided on both sides of the outer surface of the take-up roller 13. The take-up roller 13 is rotatably connected to the control box 1 through the second bearing 15. The second bearing 15 assists the take-up roller 13 to rotate on the first protective housing 6 and the second protective housing 11, so as to avoid friction between the first protective housing 6, the second protective housing 11 and the take-up roller 13.
[0033] In this embodiment, the liquid storage chamber 2 and the cavity 10 are filled with lubricating fluid. Both the liquid storage chamber 2 and the cavity 10 are provided with an inlet and an outlet. The lubricating fluid enters the liquid storage chamber 2 and the cavity 10 through the inlet, while the outlet can discharge the waste lubricating fluid.
[0034] In this embodiment, the liquid storage chamber 2 is connected to the input end of the booster pump 5 through the liquid outlet, the output end of the booster pump 5 is connected to the hose 4, and the spray head 3 is connected to the hose 4. The booster pump 5 can send the lubricating liquid in the liquid storage chamber 2 into the spray head 3 along the hose 4, and the lubricating liquid is then discharged from the spray head 3, so that the lubricating liquid can be applied to the traction rope.
[0035] In this embodiment, the control box 1 is equipped with a partition, and the control box 1 forms a control area and a liquid storage chamber 2 through the partition. The spray head 3 consists of a buffer and a spray head. The buffer on the spray head 3 can prevent the spray head from being damaged by high-pressure lubricating fluid.
[0036] Working principle: When the user starts the electric winch, the motor 7 will generate noise due to vibration. The first sound-absorbing cotton 8 and the second sound-absorbing cotton 9 absorb the noise generated by the motor 7, reducing the noise generated when the motor 7 is working. When the output end of the motor 7 drives the winding roller 13 to rotate, the first bearing 14 and the second bearing 15 cooperate to prevent the winding roller 13 from rubbing against the first protective shell 6 and the second protective shell 11 due to the pulling of the traction rope, thereby preventing the winding roller 13 from generating noise due to friction. At the same time, during the winding process of the traction rope, the booster pump 5 is started to extract the lubricating fluid in the liquid storage chamber 2 and introduce it into the spray head 3. The spray head 3 sprays the lubricating fluid onto the traction rope to lubricate the traction rope, reduce the friction coefficient of the traction rope, and thus reduce the noise generated by the friction of the traction rope.
