Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of daily maintenance of winch wire ropes, in particular to the technical field of oiling winch wire ropes, and specifically to an automatic oiling device for winch wire ropes. Background Art
[0002] The winch wire rope is an important consumable in the mining process. The maintenance of the winch wire rope directly affects the mining cost and is more related to mining safety. According to the quality standardization requirements, the winch wire rope needs to be regularly oiled and maintained during use to prevent the winch wire rope from rusting due to long-term use in the humid environment underground, which shortens the life of the winch wire rope. The traditional winch wire rope oiling method is achieved manually, that is, the winch wire rope is manually oiled during the operation of the winch. The labor intensity of the operators is high and the risk of wire rope elasticity is prone to occur during the oiling process, which poses a great safety hazard. Summary of the invention
[0003] In order to solve the problems of high labor intensity and potential safety hazards of operators in the traditional manual oiling method, the utility model provides a new automatic oiling device for winch wire rope.
[0004] The utility model is realized by adopting the following technical solutions:
[0005] The automatic oiling device for winch wire rope comprises an oiling mechanism and an oil tank. The oil tank is provided with two oil outlets. The oiling mechanism comprises a cylinder. The cylinder is cut in half along the axial direction to form two semi-cylinders distributed front and back. The upper connecting parts of the two semi-cylinders are connected by hinges. The lower connecting parts of the two semi-cylinders are connected by locking members (as is known to those skilled in the art, the locking members are generally openable, such as lock buckles, locks, etc.). Each semi-cylinder is circumferentially provided with a plurality of oil inlet holes. The oil inlet holes on the two semi-cylinders are respectively sealed with the two oil outlets of the oil tank through two oil guide assemblies. The oil-seeping cotton cloth layer and the strip-shaped elastic blocks arranged along the circumferential direction are sequentially arranged at the positions of the multiple oil inlet holes on the inner wall of each semi-cylinder in the radial direction. The fixing plate is pressed on the strip-shaped elastic block, and the oil-seeping cotton cloth layer and the strip-shaped elastic block are pressed between the fixing plate and the corresponding semi-cylinder through the cooperation of bolts and nuts. The oil-seeping cotton cloth layer in the two semi-cylinders is bent in the direction of the running of the winch wire rope to form two bending parts for tightly wrapping the winch wire rope. The friction between the two bending parts and the running winch wire rope can cause the strip-shaped elastic block to deform, thereby causing the oil inlet hole to open.
[0006] When in use, arrange the oil tank above the oiling mechanism (the oil tank can be placed somewhere or several lifting rings can be fixed on the oil tank and hung somewhere), arrange the oiling mechanism somewhere, open the locking piece, wrap the winch wire rope tightly between the bent parts of the two oil-permeable cotton cloth layers, close the locking piece, add grease to the oil tank, start the winch, and the winch wire rope runs. The winch wire rope rubs against the bent parts of the two oil-permeable cotton cloth layers, causing the strip elastic block to deform, thereby opening the oil inlet hole, and grease flows out to the oil-permeable cotton cloth. Because the oil-permeable cotton cloth squeezes and wraps the wire rope, grease is applied to the surface of the winch wire rope during operation, thereby completing the automatic oiling and maintenance operation of the winch wire rope.
[0007] Furthermore, two semicircular baffles of the same specification are fixed at the openings at both ends of the two semi-cylinders, and the two semicircular baffles at the same end form a circular baffle, and the inner hole of the circular baffle is used to pass the winch wire rope. The design of this structure can prevent grease from flowing out of the oiling mechanism and avoid pollution to the surrounding environment.
[0008] Furthermore, the two oil guide assemblies each include an oil guide tank having an inlet and multiple outlets and fixed to the outer wall of the corresponding semi-cylinder, an oil inlet connecting pipe, and multiple oil outlet connecting pipes with the same number as the outlets on the oil guide tank. One end of the oil inlet connecting pipe is connected to the corresponding oil outlet of the oil tank, and the other end of the oil inlet connecting pipe is connected to the inlet of the oil guide tank. The multiple oil inlet holes on each semi-cylinder are respectively connected to the multiple outlets on the corresponding oil guide tank through the multiple oil outlet connecting pipes, and the structure is concretized and standardized.
[0009] Furthermore, each semi-cylinder has four oil inlet holes which are circumferentially distributed in the middle of the semi-cylinder in the axial direction.
[0010] Furthermore, the four oil inlet holes on each semi-cylinder are all located in the middle and / or upper part of the corresponding semi-cylinder. Due to its own weight, if the oil inlet hole of the semi-cylinder is set at the lower part of the semi-cylinder, most of the grease overflowing from the oil inlet hole of the semi-cylinder will accumulate at the bottom of the semi-cylinder and will not play the role of oiling.
[0011] The beneficial effects produced by the utility model are as follows: the automatic oiling device for the winch wire rope in the utility model is adopted to effectively improve the oiling efficiency of the winch wire rope, reduce the labor intensity of the operators, avoid the injury incidents caused by the winch wire rope elastic rope during manual oiling, eliminate the operational risks brought by manual oiling, realize automatic oiling of the wire rope, and has a simple structure and low manufacturing cost.

The upper connecting parts of the two semi-cylinders 3 are connected by hinges 4, and the lower connecting parts of the two semi-cylinders 3 are connected by locking members 5 (it is well known to those skilled in the art that the locking members 5 are generally openable, such as lock buckles, locks, etc.). Each semi-cylinder 3 is circumferentially distributed with a plurality of oil inlet holes. The oil inlet holes on the two semi-cylinders 3 are sealed and connected with the two oil outlets of the oil tank 1 through two oil guide assemblies. At the positions of the multiple oil inlet holes on the inner wall of each semi-cylinder 3, oil-permeable cotton cloth layers 6 and strip elastic blocks 7 arranged along the circumferential direction are sequentially blocked in the radial direction. The fixing plate 8 is pressed on the strip elastic block and the oil-permeable cotton cloth layer 6 and the strip elastic block 7 are pressed between the fixing plate 8 and the corresponding semi-cylinder 3 by bolts and nuts. The oil-permeable cotton cloth layers 6 in the two semi-cylinders 3 are bent in the direction of the running of the winch wire rope 10 to form two bending parts for tightly wrapping the winch wire rope 10. The friction between the two bending parts and the running winch wire rope 10 can cause the strip elastic block 7 to deform, thereby causing the oil inlet hole to open.

Because the oil-permeable cotton cloth squeezes and wraps the wire rope, grease is applied to the surface of the winch wire rope 10 during operation, thereby completing the automatic oiling maintenance operation of the winch wire rope 10.
[0023] In specific implementation, two semicircular baffles 9 of the same specification are fixed at the openings at both ends of the two semi-cylinders 3. The two semicircular baffles 9 at the same end form a circular baffle, and the inner hole of the circular baffle is used to pass the winch wire rope 10. The design of this structure can prevent grease from flowing out of the oiling mechanism and avoid pollution to the surrounding environment.

[0026] In specific implementation, the four oil inlet holes on each semi-cylinder 3 are all located in the middle and / or upper part of the corresponding semi-cylinder 3. Due to its own weight, if the oil inlet hole of the semi-cylinder 3 is set at the lower part of the semi-cylinder 3, most of the grease overflowing from the oil inlet hole of the semi-cylinder 3 will accumulate at the bottom of the semi-cylinder 3, and will not play the role of oiling.
[0027] During specific implementation, the two oil outlets are located at the bottom of the oil tank 1 .
