Description

Technical Field

[0001] This application relates to the field of electric winch technology, specifically an electric winch for traction excavators to climb slopes. Background Technology

[0002] An electric winch is a traction device driven by the vehicle's own electric power system. Its core is to convert electrical energy into mechanical energy to lift, drag, or move heavy objects. For example, when an excavator is climbing a slope, it plays an auxiliary role when it cannot climb the slope on its own due to reasons such as the slope being too steep or the ground being slippery, so that the excavator can climb the slope smoothly. For example, the patent with publication number CN108880072A specifically discloses an electric winch. The electric winch uses a motor to drive a winch drum to unwind the wire rope wound on the winch drum. Then, the unwound end of the wire rope is connected to a fixed object. Subsequently, the motor drives the winch drum to wind up the wire rope, thereby driving the electric winch itself to move and driving the equipment connected to the electric winch to be lifted, dragged, or moved. Although the aforementioned patent can enable the lifting, dragging, or moving of equipment, the wire rope of the electric winch is made of multiple strands of twisted steel wire. During the winding and unwinding of the wire rope, the wire rope may generate significant friction with other equipment, which leads to increased wear of the wire rope and a reduction in its service life. Therefore, it is necessary to provide an electric winch for traction excavators to climb slopes to solve the above problems.

[0003] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

Detailed Implementation

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0017] like Figures 1-3 As shown, this application provides an electric winch for traction excavators climbing slopes, including a housing 1, which is assembled from multiple steel plates and can be connected to the excavator. A winch assembly 2 is disposed inside the housing 1, which is used for winding and unwinding the wire rope to assist the excavator in traction. Specifically: The winch assembly 2 includes a fixed frame 21 fixedly installed on one side of the housing 1. Two sets of rollers 22 are rotatably mounted on the fixed frame 21. The rollers 22 are arranged symmetrically up and down, and there is a certain gap between the two sets of rollers 22 to facilitate the passage of the wire rope during subsequent winding and unwinding. As the angle and position of the wire rope relative to the excavator are constantly changing, the rollers 22 can guide the wire rope to reduce friction and prevent excessive wear of the wire rope when it passes through. An installation bracket 23 is fixedly installed inside the housing 1. A spool (not shown in the figure) is rotatably mounted on the installation bracket 23. A steel wire rope 25 is wound on the spool. A locking hook 26 is provided at one end of the steel wire rope 25. A slot (not shown in the figure) is provided through one side of the housing 1. The slot is located on one side of the gap between the two sets of rollers 22 so that the locking hook 26 can pass through the slot and the gap and be located on one side of the rollers 22. A motor 24 is installed on one side of the mounting frame 23. The output end of the motor 24 is connected to the winding drum so that the winding drum can be rotated under the drive of the motor 24, thereby winding or unwinding the wire rope 25. When the excavator needs to be towed while climbing a slope, the motor 24 drives the reel to unwind, and then connects the locking hook 26 to other fixed objects. The motor 24 drives the reel to wind up. At this time, the locking hook 26 is fixed in place because it is connected to the fixed objects. The winding of the reel will drive the housing 1 to move, thereby towing the excavator to assist it in climbing the slope. A maintenance component 3 is provided on the fixing frame 21. The maintenance component 3 is used for the lubrication of the wire rope 25 to further reduce the friction of the wire rope 25. like Figures 1-4 As shown, the maintenance component 3 includes a top plate 32 mounted on a mounting bracket 21, and a vertical plate 31 is fixedly mounted on one end of the top plate 32; A support frame 35 is fixedly installed on the vertical plate 31. An oil storage box 34 is fixedly installed on the support frame 35. The oil storage box 34 stores grease suitable for lubricating the wire rope 25. An oil pipe 36 is provided at the oil outlet of the oil storage box 34. A nozzle is provided at the bottom end of the oil pipe 36. A solenoid valve (not shown in the figure) is provided on the oil pipe 36. So that the oil pipe 36 can be opened and closed by controlling the solenoid valve, and then the grease in the oil storage box 34 can be sprayed onto the wire rope 25 through the nozzle, thereby lubricating the wire rope 25 and reducing the friction between the wire rope 25 and other equipment. A cleaning ring 33 adapted to the wire rope 25 is detachably installed at the bottom end of the vertical plate 31. The cleaning ring 33 has a brush so that the wire rope 25 can pass through the cleaning ring 33 and the brush is in contact with the surface of the wire rope 25. So that when the wire rope 25 is wound up, the surface of the wire rope 25 can be cleaned with a brush to avoid the wire rope 25 being left uncleaned during winding, which would cause corrosion to the wire rope 25 and cause the accumulation of dirt during the next use, resulting in poor lubrication of the wire rope 25. Continue to refer to Figure 4 A first fixing box 37 is fixedly installed on one side of the vertical plate 31. Multiple sets of connecting blocks 4 are installed on the first fixing box 37. A second fixing box 42 is installed on the end of the connecting block 4 away from the first fixing box 37. Both the first fixing box 37 and the second fixing box 42 are provided with through holes adapted to the steel wire rope 25 so that the steel wire rope 25 can pass through the through holes. Both the first fixed box 37 and the second fixed box 42 are provided with cavities. Both sets of cavities are rotatably provided with rings 39. Multiple sets of connecting rods 41 are provided between the two sets of rings 39. A driven gear (not shown in the figure) is provided on one of the rings 39. A protrusion is provided on the first fixed box 37. A driving gear is installed on the protrusion. The driving gear and the driven gear are meshed and connected. A motor 38 is mounted on the convex plate. The output end of the motor 38 is connected to the drive gear. Under the drive of the motor 38, the two sets of rings 39 are rotated through the drive gear and the driven gear. It should be noted that the nozzle is located above the two sets of rings 39, and sponges are provided on the multiple sets of connecting rods 41, so that the sponges are in contact with the surface of the wire rope 25. Thus, when grease is sprayed onto the wire rope 25, the sprayed grease can drip onto the sponge, and the motor 38 can be started to drive the connecting rods 41 to rotate through the rings 39, thereby driving the sponge to rotate and evenly applying the grease to the surface of the wire rope 25.

[0018] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
