Description

Technical Field

[0001] This utility model relates to the field of rope lubrication technology, and in particular to a lubrication device for steel wire ropes used in cranes. Background Technology

[0002] Cranes are typically driven by external forces via ropes or linkages, i.e., rope-driven mechanical grabs. The ropes used in rope-driven mechanical grabs consist of a support rope and an opening / closing rope, wound on drums of the support and opening / closing mechanisms respectively. The support rope and opening / closing rope descend simultaneously, opening the bucket mouth to insert into the material pile. When the opening / closing rope is tightened, the jaws close and grab the material. After the grab closes, the support rope and opening / closing rope rise simultaneously. When the support rope is stationary, the opening / closing rope descends, opening the bucket mouth to unload the material. The ropes used in rope-driven mechanical grabs are usually steel wire ropes. Before being wound around the grab, the steel wire ropes undergo treatment because they need to bear enormous loads, resulting in severe wear during operation. Under current conditions, lubrication is used to reduce wear and tear.

[0003] For example, CN221324101U discloses a wire rope lubrication device and engineering machinery. This method of lubricating wire ropes through a lubrication device offers high operational efficiency, good lubrication effect, and low operational difficulty. However, existing wire ropes are long and often use roller structures for winding and packaging. If the lubrication device cannot easily disassemble and pull the rollers used for winding the wire rope, it is difficult to achieve dynamic traction of the wire rope, and even more difficult to lubricate every part of the wire rope. In particular, the crude method of lubricating oil application not only easily leads to waste of lubricating oil but also makes it difficult to ensure comprehensive lubrication. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that it is difficult to fix and drive wire ropes, making lubrication and protection inconvenient, and to propose a wire rope lubrication device for cranes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wire rope lubrication device for cranes includes a housing with symmetrical mounting slots on its left and right sides. A first cylinder is fixedly mounted on the outside of the housing. The housing is connected to the first cylinder via the mounting slots and a limiting mechanism for mounting two wire rope rollers and pulling the wire rope to one side. A load-bearing bracket is integrally connected to the top of the housing, and the housing is connected to the load-bearing bracket for tensioning and supporting the wire rope and for applying oil. An oiling component is also provided inside the housing to work with the oiling component to apply oil evenly.

[0007] Preferably, the limiting mechanism includes a traction swing rod rotatably installed in the mounting groove and movably pulled by the output end of the first cylinder.

A limiting sleeve for initially mounting the end of the wire rope roller is rotatably installed on the telescopic straight rod, and a locking bolt for locking and fixing the end of the wire rope roller is installed in the limiting sleeve.

[0008] Preferably, a traction link is connected between the output end of the first cylinder and the lower end of the traction swing arm via a pin. A traction long hole is provided at the upper end of the traction swing arm, and a traction long bolt that is slidably fitted into the traction long hole is integrally connected to the telescopic straight rod.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A wire rope lubrication device for cranes includes a housing 1, with mounting slots 2 symmetrically opened on the left and right sides of the housing 1, and a first cylinder 3 fixedly installed on the outside of the housing 1.

[0023] Please refer to the instruction manual for details. Figure 1 -Appendix Figure 3The housing 1 is equipped with a limiting mechanism 4 for installing two wire rope rollers and pulling the wire rope to one side via the mounting groove 2 and the first cylinder 3. It should be noted that the limiting mechanism 4 includes a traction swing rod 401 rotatably installed in the mounting groove 2 and movably pulled by the output end of the first cylinder 3. A telescopic straight rod 403 slidably fitted at the top of the mounting groove 2 and movably pulled by the traction swing rod 401 is rotatably fitted on the telescopic straight rod 403 for initially fitting the end of the wire rope roller. The limiting sleeve 406 is installed in the limiting sleeve 406 for locking and fixing the end of the wire rope roller. Through opposing clamping and angle fixing, the wire rope rollers can be easily installed and removed. At the same time, by setting a mechanism on one side of the housing 1 to drive the rotation of a certain wire rope roller, the wire rope is pulled, so that the wire rope passes through the housing 1 in an orderly manner.

[0024] Please refer to the instruction manual for details. Figure 3 With appendix Figure 4 The top of the casing 1 is integrally connected to a load-bearing bracket 5, and the casing 1 is equipped with an oiling assembly for tensioning and supporting the wire rope and for injecting oil through the load-bearing bracket 5. The oiling assembly includes a second cylinder 6 fixedly installed on the load-bearing bracket 5. Guide vertical grooves 7 are symmetrically opened on the front and rear sides of the casing 1, and a lifting frame 8 fixedly connected to the output end of the second cylinder 6 is slidably installed in the guide vertical grooves 7. A pressure roller 9 for pressing the wire rope downward is rotatably installed on the lifting frame 8. By driving the pressure roller 9 to rise and fall vertically, the middle part of the wire rope bends to the lower end of the casing 1, so that the wire rope can move in an orderly and taut manner. At this time, the wire rope has a U-shaped structure. An oiler 10 for injecting lubricating oil into the wire rope is fixedly installed on the load-bearing bracket 5. The lubricating oil is injected into the wire rope passing through the pressure roller 9 through the oiler 10, so that the lubricating oil comes into contact with the wire rope.

[0025] Please refer to the instruction manual for details. Figure 4 The machine housing 1 is also equipped with an oiling component that works with the oiling component to apply the oil evenly. The oiling component includes a guide rail 11 integrally connected to the bottom of the machine housing 1. The guide rail 11 is equipped with an integral reciprocating drive 12 and a moving frame 13. A strong spring 14 is fixedly installed on the moving frame 13, and a moving brush 15 is fixedly installed on the strong spring 14. The moving brush 15 is slidably fitted in the moving frame 13 and moves against the steel wire rope. During the reciprocating movement of the moving brush 15 in the left and right direction, it moves up and down due to the support of the strong spring 14 and the pressing action of the pressure roller 9, ensuring that the moving brush 15 makes dynamic contact with the steel wire rope and evenly applies the lubricating oil to the steel wire rope.

[0026] A traction link 402 is pin-connected between the output end of the first cylinder 3 and the lower end of the traction swing arm 401. A traction long hole 404 is provided at the upper end of the traction swing arm 401, and a traction long bolt 405 is integrally connected to the telescopic straight rod 403 and slidably fitted into the traction long hole 404. During the deflection process, the traction swing arm 401 drives the two telescopic straight rods 403, which are symmetrically arranged in front and behind, to move towards or in opposite directions, so as to facilitate the convenient disassembly and assembly of the end of the wire rope roller using the limiting sleeve 406.

[0027] The oiler 10 is located above the pressure roller 9, and the oiling assembly is located below the oiling assembly, so as to inject oil into each part of the wire rope passing through the pressure roller 9, and at the same time use the movable brush 15 to evenly apply the lubricating oil to the parts that come into contact with it.

[0028] It should be noted that the specific models and specifications of the first cylinder 3, the second cylinder 6, the oil injector 10 and the reciprocating drive 12 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0029] The functional principle of this utility model can be explained through the following operation methods:

[0030] Steel wire rope rollers are placed at the top of the mounting slots 2 on the left and right sides of the chassis 1. The first cylinder 3 is opened. The output end of the first cylinder 3 drives the traction swing rod 401 to deflect through the traction connecting rod 402. The traction swing rod 401 drives the telescopic straight rods 403 arranged symmetrically in front and behind to move towards each other through the traction bolt 405, so that the limiting sleeve 406 is fitted onto the end of the steel wire rope roller.

[0031] Tighten the locking bolt 407 on the limit sleeve 406 to fix the wire rope roller in place;

[0032] The second cylinder 6 is opened on the load-bearing bracket 5, so that the lifting frame 8 drives the pressure roller 9 to move vertically downward, making the steel wire rope tend to be taut.

[0033] By driving a steel wire rope roller to rotate, the steel wire rope can be moved in an orderly manner;

[0034] Lubricating oil is injected into the wire rope through the oiler 10, while the moving frame 13 is driven to move back and forth left and right through the reciprocating drive 12. Due to the support of the strong spring 14, the moving brush 15 dynamically rubs against the wire rope on the pressure roller 9 to evenly apply the lubricating oil to the wire rope.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
