Description

Technical Field

[0001] This utility model relates to the field of hydraulic winch technology, and in particular to hydraulic winches used in underground mines. Background Technology

[0002] Common underground hydraulic winches are mainly used in the construction of vertical shafts in coal mines, metal mines and non-metal mines to suspend equipment such as hoisting platforms, water pumps, and ventilation ducts, and to undertake the task of tensioning and stabilizing ropes.

[0003] For example, Chinese patent application CN202020536932.9 discloses a novel hydraulic winch for underground use, which specifically includes a base, a first clamping plate at the upper end of the base, an indicator plate at the upper end of the first clamping plate, a connecting frame at the upper end of the indicator plate, a drive assembly at the upper end of the connecting frame, a housing at the upper end of the drive assembly, a reduction connector at the upper end of the housing, a drum at the upper end of the reduction connector, a mechanical braking assembly at the upper end of the drum, a load-bearing frame at the upper end of the mechanical braking assembly, a bearing at the upper end of the load-bearing frame, and a second clamping plate at the lower end of the base. However, it still has the following technical problems: When items are suspended for a long time, dust usually adheres to the wire rope. Once the wire rope with dust is wound onto the hydraulic winch, it is difficult to clean. The dust that adheres to the wire rope for a long time will easily cause wear, corrosion and aging of the wire rope and hydraulic winch, thus shortening the service life of the equipment. It can be seen that the above structure is difficult to clean the dust and dirt on the wire rope. Utility Model Content

[0004] To address the problem of difficulty in cleaning dust and dirt from steel wire ropes as mentioned in the background section, this utility model provides the following technical solution: A hydraulic winch for underground use, comprising a hydraulic winch body; The front end of the hydraulic winch body is equipped with a limiting component, which includes a limiting plate. A rotating ring is installed at the front end of the limiting plate, and multiple bristles for cleaning the wire rope are installed on the inner wall of the rotating ring.

[0005] The limiting component includes a gear for controlling the rotation of the rotating ring.

[0006] The limiting component includes a rotating rod, one end of which is equipped with a rotating wheel for cooperating with a wire rope to control the rotation of the rotating rod, and the other end of the rotating rod is equipped with a bevel gear two for facilitating the rotation of the control gear.

[0007] Furthermore, a limiting block for limiting the limiting component is installed at the front end of the hydraulic winch body, and a sliding groove for the limiting component to slide is provided in the middle of the limiting block.

[0008] Furthermore, the limiting component includes a T-shaped moving block, with balls installed at both the upper and lower ends of the T-shaped moving block to facilitate its sliding within the groove. A through hole is provided in the middle of the T-shaped moving block for the steel wire rope to pass through, and the through hole passes through the middle of the limiting plate.

[0009] Furthermore, the through hole and the central cavity of the rotating ring are concentric circles, the bristles are obliquely installed on the inner wall of the rotating ring, and one end of the bristles extends to the outside of the front end of the rotating ring. The outer wall of the rear end of the rotating ring is equipped with a plurality of tooth blocks for meshing with gears.

[0010] Furthermore, the gear is connected to a bevel gear one that meshes with the bevel gear two via a rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are: As the wire rope moves, it synchronously drives the rotating wheel to rotate, which in turn drives the rotating rod to rotate. The second bevel gear synchronously drives the first bevel gear to rotate, which in turn drives the gear to rotate through the rotating shaft. The gear and the tooth block drive the rotating ring to rotate, and the rotating ring synchronously drives multiple bristles to move in a circular motion on the outer wall of the wire rope. The multiple bristles synchronously sweep the dust off the outer surface of the wire rope to reduce the accumulation of dust on the outer surface of the wire rope, and avoid excessive dust from accelerating the wear, corrosion and aging of the wire rope, thereby increasing the service life of the wire rope and reducing the frequency of manual cleaning of the wire rope.

[0018] Please see Figures 1-3 This utility model provides a hydraulic winch for underground use, including a hydraulic winch body 100. A limiting member 200 is movably installed at the front end of the hydraulic winch body 100 by bolts, and the limiting member 200 can move left and right with the wire rope. A limiting block 110 for limiting the limiting member 200 is fixedly installed at the front end of the hydraulic winch body 100 by bolts. A sliding groove 111 for the limiting member 200 to slide is opened in the middle of the limiting block 110. Threaded holes are opened simultaneously on the support plates on the left and right sides of the hydraulic winch body 100, so that the bolts on the left and right sides of the limiting block 110 can be screwed into the corresponding threaded holes on the hydraulic winch body 100 to fix the limiting block 110, so that the limiting member 200 can slide in the sliding groove 111.

[0019] The limiting component 200 includes a T-shaped movable block 210. Both the upper and lower ends of the T-shaped movable block 210 are movably equipped with ball bearings 211 to facilitate sliding of the T-shaped movable block 210 within the slide groove 111. The arrangement of multiple ball bearings 211 ensures smooth sliding of the T-shaped movable block 210 within the slide groove 111. A through hole 212 is provided in the middle of the T-shaped movable block 210 for the steel wire rope to pass through, and the through hole 212 passes through the middle of the limiting plate 220, allowing the steel wire rope to pass through both the T-shaped movable block 210 and the limiting plate 220 for suspension operations.

[0020] The limiting component 200 includes a limiting plate 220, with a rotating ring 230 movably mounted at the front end of the limiting plate 220. The through hole 212 and the central cavity of the rotating ring 230 are concentric circles to facilitate the passage of the wire rope through the center of the rotating ring 230. The rotating ring 230 is rotatably connected to the front end of the limiting plate 220. Multiple bristles 231 for cleaning the wire rope are fixedly installed on the inner wall of the rotating ring 230. The bristles 231 are obliquely installed on the inner wall of the rotating ring 230, and one end of the bristles 231 extends to the outside of the front end of the rotating ring 230. When the wire rope moves and the rotating ring 230 rotates, the multiple bristles 231 sweep off the dust on the wire rope to reduce the amount of dust on the wire rope, avoid excessive dust from accelerating the wear, corrosion and aging of the wire rope, thereby increasing the service life of the wire rope and reducing the frequency of manual cleaning of the wire rope.

[0021] The limiting member 200 includes a gear 240 for controlling the rotation of the rotating ring 230. The limiting member 200 also includes a rotating rod 250, which is mounted on the rear end of the T-shaped moving block 210 via a bearing seat. One end of the rotating rod 250 is fixedly mounted with a rotating wheel 251 for cooperating with the wire rope to control the rotation of the rotating rod 250. The surface of the rotating wheel 251 is roughened. When the wire rope enters the through hole 212, the wire rope bends at the rotating wheel 251, causing the rotating wheel 251 and the wire rope to be in close contact. When the wire rope moves, it synchronously drives the rotating wheel 251 to rotate, and the rotating wheel 251 in turn drives the rotating rod 250 to rotate.

[0022] The other end of the rotating rod 250 is fixedly equipped with a bevel gear 252, which facilitates the rotation of the gear 240. The gear 240 is connected to a bevel gear 241 that meshes with the bevel gear 252 via a rotating shaft. When the rotating rod 250 drives the bevel gear 252 to rotate, the bevel gear 252 synchronously drives the bevel gear 241 to rotate, so that the bevel gear 241 synchronously drives the gear 240 to rotate via the rotating shaft. The outer diameter of the gear 240 is larger than the outer diameter of the bevel gear 241, so that when the bevel gear 241 rotates one revolution, the gear 240 drives the rotating ring 230 to rotate at a faster speed, which facilitates the rapid sweeping of dust off the wire rope.

[0023] Multiple toothed blocks 232 for meshing with gear 240 are fixedly installed on the outer wall of the rear end of the rotating ring 230. The gear 240, in conjunction with the toothed blocks 232, drives the rotating ring 230 to rotate. The rotating ring 230 simultaneously drives multiple bristles 231 to perform circumferential motion on the outer wall of the wire rope. The multiple bristles 231 simultaneously sweep dust off the outer surface of the wire rope to reduce the accumulation of dust on the outside of the wire rope.

[0024] The rear end of the T-shaped moving block 210 is equipped with a protective cover for protecting the first bevel gear 241 and the second bevel gear 252, and the front end of the moving part 220 is equipped with a protective cover for protecting the tooth block 232 and then the gear 240, so as to prevent dust from adhering and affecting the transmission effect.

[0025] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
