Description
Technical Field
[0001] The utility model relates to the technical field of maintenance devices, and particularly relates to a wire rope maintenance device for a small crawler crane. Background Technique
[0002] A crawler crane is a boom rotating crane that uses crawlers to move. The crawler has a large grounding area, good passability, strong adaptability, and can travel with load, making it suitable for lifting operations at construction sites.
[0003] Since the wire rope will be affected by stretching, bending, friction and external environmental factors (such as humidity, dust, corrosive media, etc.) during use, its performance will gradually decline, and problems such as wear, rust, and broken wires will occur. This will not only shorten the service life of the wire rope, but may also cause safety accidents, threatening the safety of personnel and equipment. In order to ensure the safe and reliable operation of the small crawler crane and extend the service life of the wire rope, it is very necessary to perform regular maintenance on the wire rope.
[0004] In the patent document of a wire rope maintenance device for a small crawler crane with the publication number of CN222518999U, it includes a housing. There is an empty opening inside the housing. Two groups of hydraulic rod devices are oppositely arranged inside the empty opening. Clamping rings one and two are respectively fixedly connected to the telescopic ends of the hydraulic rod devices. Spring chambers are provided on both the clamping ring one and the clamping ring two. Spring members are provided inside the spring chambers. Both ends of the spring members are fixedly connected to the spring chambers on the clamping ring one and the clamping ring two respectively. An oil inlet pipe is fixedly connected to the housing. The oil inlet pipe is fixedly connected to the hydraulic rod device. The liquid outlet end of the oil inlet pipe is used to spray wire rope oil on the surface of the crane wire rope. Through the injection of wire rope oil, the hydraulic rod device extends, and then the clamping ring one and the clamping ring two are attached to each other, squeezing the wire rope of the crane. Then the wire rope oil will pass through the oil outlet openings located inside the clamping ring one and the clamping ring two to maintain the wire rope of the crane. And when the wire rope oil is not injected, the clamping ring one and the clamping ring two no longer clamp the wire rope of the crane to prevent wear caused by mutual friction. However, the above patent document still has the following defects in the implementation process:
[0005] This device wets the surface of the wire rope through absorbent cotton to achieve the effect of maintaining the wire rope. Due to the uneven surface and bending of the wire rope, some parts of the wire rope will not receive enough oil, resulting in uneven maintenance, affecting the overall maintenance effect and service life of the wire rope.

DETAILED DESCRIPTION
[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0027] Embodiment 1: Figure 1-6 As shown, a wire rope maintenance device for a small crawler crane includes a fixed base 1, and two maintenance boxes 11 are in contact with each other above the fixed base 1. The two maintenance boxes 11 are in contact with each other, and a wire rope 12 is commonly arranged inside the two maintenance boxes 11. A plurality of plug holes are opened at the right end of the maintenance box 11 located on the left, and a plurality of plug rods are fixedly connected to the left end of the maintenance box 11 located on the right, and the outer surfaces of the plurality of plug rods are plugged into the plug holes on the same side, maintenance components 2 are arranged inside the two maintenance boxes 11, and a moving component 3 is arranged above the fixed base 1.
[0028] Specifically, in order to achieve the goal of evenly maintaining all parts of the wire rope, refer to Figure 4 and Figure 5 In this embodiment, the maintenance component 2 includes two fixed blocks 21, the bottoms of the two fixed blocks 21 are fixedly connected to the top of the maintenance box 11 on the same side, and the inner walls of the two fixed blocks 21 are rotatably connected to a rotating shaft 211.
[0029] For further information, see Figure 5 In this embodiment, the left and right ends of the rotating shaft 211 are fixedly connected with a bevel gear 213, and the outer surface of the rotating shaft 211 is fixedly connected with a rotating wheel 212, and the outer surface of the rotating wheel 212 contacts the outer surface of the wire rope 12.
[0030] During the implementation process, when it is necessary to use the device to maintain the wire rope 12, first start the crane, which will drive the wire rope 12 to operate, and transport maintenance oil to the corresponding spray tank 22 through two pipes. The maintenance oil entering the spray tank 22 will be sprayed onto the surface of the wire rope 12 through the nozzle on its surface. At the same time, when the wire rope 12 is running, it will drive the two rotating wheels 212 to rotate, and when the rotating wheels 212 rotate, they will drive the two bevel gears 213 to rotate.
[0031] For further information, see Figure 4 In this embodiment, the inner wall of the maintenance box 11 is fixedly connected to the spray box 22, and the inner wall of the maintenance box 11 is rotatably connected to two rotating shafts 23. The tops of the two rotating shafts 23 are fixedly connected to bevel gears 232. The tops of the two bevel gears 232 are meshed with the bottoms of the bevel gears 213 on the same side, and the outer surfaces of the two rotating shafts 23 are fixedly connected to a plurality of brushes 231.

[0033] During the implementation process, when the bevel gear 1 213 rotates, the bevel gear 2 232 will be driven to rotate. When the bevel gear 232 rotates, the rotating shaft 1 23 will be driven to rotate. When the rotating shaft 1 23 rotates, several brushes 231 will be driven to rotate. When the rotating shaft 1 23 located on the left front side and the rotating shaft 1 23 located on the right back side rotate, they will both drive the corresponding belt pulley 1 25 to rotate. When the belt pulley 1 25 rotates, it will drive the rotating shaft 2 24 to rotate in the corresponding maintenance box 11 inner wall through the belt 1 251. When the rotating shaft 24 rotates, it will drive several brushes 2 241 to rotate. The rotating brushes can better adapt to the unevenness and curvature of the wire rope surface through their own rotation and the elasticity of the bristles, so that all parts of the surface of the wire rope 12 can be more evenly maintained, effectively improving the maintenance effect and extending the service life of the wire rope.
[0034] Embodiment 2: This embodiment sets a mobile component based on embodiment 1.
[0035] Specifically, in order to achieve the purpose of increasing the service life of the brush, refer to Figure 2 and Figure 3 In this embodiment, the moving assembly 3 includes four fixed frames 31, the bottoms of the four fixed frames 31 are fixedly connected to the top of the fixed base 1, and two bidirectional threaded rods 32 are arranged above the fixed base 1. The front and back outer surfaces of the two bidirectional threaded rods 32 are rotatably connected to the inner wall of the fixed frame 31 on the same side.
[0036] For further information, see Figure 2In this embodiment, the front side of the fixed frame 31 located on the left side of the front side is fixedly connected to a motor 311, and the output end of the motor 311 is fixedly connected to the front side of the bidirectional threaded rod 32 on the same side, and the back sides of the two bidirectional threaded rods 32 are fixedly connected to a belt pulley 34, and the outer surfaces of the two belt pulleys 34 are commonly connected to a belt 341 for transmission.
[0037] For further information, see Figure 3 In this embodiment, the outer surfaces of the two bidirectional threaded rods 32 are threadedly connected with a moving frame 33, and the ends of the two moving frames 33 close to the maintenance box 11 are fixedly connected to the outer surface of the maintenance box 11 on the same side. Two sliding grooves are provided on the top of the fixed base 1, and the inner walls of the two sliding grooves are slidably connected with sliding blocks 35, and the tops of the two sliding blocks 35 are fixedly connected to the bottom of the maintenance box 11 on the same side.
[0038] When the two maintenance boxes 11 are moved, the surface of the wire rope 12 is completely exposed, which is convenient for the staff to inspect, maintain and repair the wire rope 12.
[0039] The working principle of the utility model is as follows: when the device is needed to maintain the wire rope 12, the crane is first started, the crane drives the wire rope 12 to operate, and the maintenance oil is respectively transported to the corresponding spray tank 22 through two pipes, and the maintenance oil entering the spray tank 22 is sprayed onto the surface of the wire rope 12 through the nozzle on its surface, and at the same time, the wire rope 12 drives the two rotating wheels 212 to rotate when it operates, and the rotating wheels 212 drive the two bevel gears 1 213 to rotate when they rotate, and the bevel gear 1 213 drives the bevel gear 2 232 to rotate when it rotates, and the rotating shaft 1 23 drives the rotating shaft 23 to rotate when the bevel gear 232 rotates. When shaft 23 rotates, several brushes 231 are driven to rotate. When shaft 23 located on the left front side and shaft 23 located on the right back side rotate, the corresponding belt pulley 25 is driven to rotate. When belt pulley 25 rotates, shaft 24 is driven to rotate in the corresponding inner wall of maintenance box 11 through belt 251. When shaft 24 rotates, several brushes 241 are driven to rotate. The rotating brushes can better adapt to the unevenness and curvature of the surface of the wire rope through their own rotation and the elasticity of the bristles, so that all parts of the surface of the wire rope 12 can be maintained more evenly, effectively improving the maintenance effect and extending the service life of the wire rope.
[0040] When the device completes maintenance of the wire rope 12, the motor 311 is turned on to drive the bidirectional threaded rod 32 to rotate counterclockwise in the inner walls of the corresponding two fixed frames 31. When the bidirectional threaded rod 32 rotates, it will drive the second belt pulley 34 to rotate. When the second belt pulley 34 rotates, it will drive the second belt 341 to rotate. When the second belt 341 rotates, it will drive the other second belt pulley 34 to rotate, so that the two bidirectional threaded rods 32 can rotate at the same time. When the bidirectional threaded rod 32 rotates counterclockwise, it will drive the two moving frames 33 to move away from each other. When the moving frame 33 moves, it will drive the maintenance box 11 to move so that the two maintenance boxes 11 can be separated and no longer contacted with the surface of the wire rope 12, which not only avoids unnecessary wear of the brush 1 231 and the brush 2 241, prolongs the service life of vulnerable parts such as the brush, and reduces maintenance costs, but also after the two maintenance boxes 11 are removed, the surface of the wire rope 12 will be completely exposed, which is convenient for the staff to inspect, maintain and overhaul the wire rope.
