Technical Field

[0001] This utility model relates to the field of lubrication devices, specifically to a winch wire rope lubrication device. Background Technology

[0002] In underground coal mine operations, the wire ropes of winches are subject to severe oxidation, corrosion, and wear due to environmental factors. If the wire ropes of the winches are not properly maintained in a timely manner, it will affect their service life and normal operation, and may even lead to safety hazards and production accidents.

[0003] In current technology, the daily lubrication of wire ropes generally involves workers manually applying oil to the wire ropes periodically. This is labor-intensive, and manual oiling often results in uneven lubrication and poor lubrication effect. Utility Model Content

[0004] The purpose of this invention is to provide a winch wire rope lubrication device that can automatically apply oil to the wire rope, thereby solving the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A winch wire rope lubrication device includes an oil tank. A vertically extending outer tube is fixedly installed on the top of the oil tank. An inner tube is vertically slidably installed inside the upper end of the outer tube. A guide wheel with a horizontally extending axis is rotatably installed on one side of the outer tube and one side of the inner tube, respectively. The guide wheel on the outer tube is located directly above the guide wheel on the inner tube. The wire rope passes between the two guide wheels. An oil supply pipe is fixedly installed on the outer tube and the inner tube, respectively. One end of the oil supply pipe is connected to the oil tank, and the other end of the oil supply pipe is provided with an oil outlet facing the top side of the corresponding guide wheel.

[0006] As a further improvement, the outer circumferential surface of the guide wheel is provided with an arc-shaped groove that matches the outer wall of the wire rope.

[0007] As a further improvement, an oiled sponge is fitted onto the outer circumferential surface of the guide wheel.

[0008] As a further improvement, a tension spring is connected between the outer tube and the inner tube to pull the inner tube downward.

[0009] As a further improvement, a vertically extending rack is fixedly installed at the lower end of the inner tube, and a horizontally extending mounting shaft is rotatably installed inside the outer tube. A gear that meshes with the rack is fixedly installed on the mounting shaft. One end of the mounting shaft extends out of the outer tube and is fixedly mounted with a swing arm. The end of the swing arm away from the mounting shaft extends downward at an angle and is fixedly mounted with a foot pedal.

[0010] As a further improvement, an oil supply pump is fixedly installed on the outside of the oil tank. The inlet side of the oil supply pump is connected to the inner cavity of the oil tank, and the inlet ends of the two oil supply pipes are respectively connected to the outlet side of the oil supply pump through hoses.

[0011] As a further improvement, the top of the oil tank is provided with an oil receiving groove, and the bottom wall of the oil receiving groove is provided with a return hole that connects to the inner cavity of the oil tank. The guide wheel is located above the oil receiving groove.

[0012] As a further improvement, the bottom of the fuel tank is equipped with casters.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The oil discharged from the two oil supply pipes drips evenly onto the outer circumference of the corresponding guide wheel through the oil outlet. As the guide wheel rotates, it evenly coats the steel wire rope with oil, eliminating the need for manual oiling and saving manpower. 2. The outer circumference of the guide wheel is surrounded by an arc-shaped groove that matches the outer wall of the wire rope, and an oiling sponge is fitted on the outer circumference of the guide wheel, so that the oiling can be carried out more evenly and efficiently through the guide wheel; 3. By stepping on the foot pedal, the mounting shaft and gear rotate clockwise. The gear drives the rack and inner tube to move upward, and the inner tube drives the guide wheel on it to move upward, increasing the distance between the upper and lower guide wheels, thus making it easier to put the wire rope that needs lubrication between the two guide wheels. 4. The top of the oil tank is recessed downwards to form an oil receiving groove, which facilitates the recycling of oil dripping from the guide wheel. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, a winch wire rope lubrication device includes an oil tank 1. A vertically extending outer tube 2 is fixedly installed on the top of the oil tank 1 by bolts. An inner tube 3 is vertically slidably installed inside the upper end of the outer tube 2. Both the outer tube 2 and the inner tube 3 are hollow square tubes. A guide wheel 4 with a horizontally extending axis is rotatably installed on the upper right side of the outer tube 2 and the upper right side of the inner tube 3, respectively. The guide wheel 4 on the outer tube 2 is located directly above the guide wheel 4 on the inner tube 3. The wire rope 5 passes between the two guide wheels 4. A horizontal oil supply pipe 6 is fixedly installed on the outer tube 2 and the inner tube 3 by mounting plates. One end of the oil supply pipe 6 is connected to the oil tank 1. The other end of the oil supply pipe 6 is bent at a 90-degree angle and has an oil outlet 7. The oil outlet 7 is inclined downward and faces the top side of the corresponding guide wheel 4.

[0019] During the process of the winch winding the wire rope 5, the wire rope 5 drives the guide wheels 4 on its upper and lower sides to rotate; at the same time, the oil discharged from the two oil supply pipes 6 drips evenly onto the outer circumference of the corresponding guide wheel 4 through the oil outlet 7, and the guide wheel 4 rolls the oil evenly onto the wire rope 5 during the rotation.

[0020] like Figure 2 As shown, in order to increase the contact area between the outer wall of the guide wheel 4 and the wire rope 5 and improve the oiling efficiency of the guide wheel 4, an arc-shaped groove 19 matching the outer wall of the wire rope 5 is provided around the outer circumference of the guide wheel 4.

[0021] To further improve the uniformity of oiling the wire rope 5, an oiling sponge 20 is fitted on the outer circumferential surface of the guide wheel 4.

[0022] In order for the upper and lower guide wheels 4 to effectively clamp the wire rope 5, a tension spring 8 is connected between the outer tube 2 and the inner tube 3 to pull the inner tube 3 downward.

[0023] like Figure 3 and Figure 4 As shown, a vertically extending rack 9 is fixedly installed at the lower end of the inner tube 3 by bolts. A horizontally extending mounting shaft 10 is rotatably installed in the outer tube 2 below the inner tube 3 by bearings. A gear 11 that meshes with the rack 9 is fixedly installed on the mounting shaft 10. When the gear 11 rotates clockwise, it drives the rack 9 to move upward. A swing arm 12 is fixedly installed at the left end of the mounting shaft 10 outside the outer tube 2 by bolts. The end of the swing arm 12 away from the mounting shaft 10 extends downward at an angle and is welded or integrally formed with a foot pedal 13. Specifically, by pressing the foot pedal 13, the swing arm 12 and the mounting shaft 10 are rotated clockwise. In turn, the mounting shaft 10 drives the gear 11 to rotate clockwise and drives the rack 9 and the inner tube 3 to move upward. The inner tube 3 drives the guide wheel 4 on it to move upward, increasing the distance between the upper and lower guide wheels 4, thus making it easier to put the wire rope 5 that needs to be lubricated between the two guide wheels 4. After the wire rope 5 is placed between the two guide wheels 4, the foot pedal 13 is released, and the tension spring 8 pulls the inner tube 3 to move downward along the outer tube 2, thereby causing the two guide wheels 4 to clamp the wire rope 5.

[0024] An oil supply pump 14 is bolted to the outside of the oil tank 1. The inlet of the oil supply pump 14 is connected to the inner cavity of the oil tank 1. The inlet ends of the two oil supply pipes 6 are connected to the outlet of the oil supply pump 14 via hoses to facilitate the supply of oil to the two oil supply pipes 6. The top of the oil tank 1 is also provided with a filler port 15 for replenishing oil into the oil tank 1.

[0025] The top of the oil tank 1 is recessed downwards to form an oil receiving groove 16. The bottom wall of the oil receiving groove 16 is provided with a return hole 17 that connects to the inner cavity of the oil tank 1. A filter screen is installed inside the return hole 17. The guide wheel 4 is located above the oil receiving groove 16. The oil dripping from the guide wheel 4 can be recovered through the oil receiving groove 16. After being filtered by the filter screen, the oil flows back into the oil tank 1 through the return hole 17 for recycling.

[0026] To facilitate the movement of the device, casters 18 are installed at the four corners of the bottom of the oil tank 1. The casters 18 are universal casters with brakes.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
