Description

Technical Field

[0001] The invention belongs to the technical field of hooks, in particular to an anti-unhooking device for an electric rake wire rope. Background Art

[0002] In mining areas, electric rakes are mainly used to transport ore from the working face to hoists or transportation equipment. They are suitable for open-pit and underground mining operations. In electric rake operations, wire ropes are usually used to connect the hook and the rake bucket so that the rake bucket can be driven by a winch or other power source to excavate, load and transport materials. However, due to the complexity of the working environment and various factors during the operation, the wire rope may sometimes fall off the hook, resulting in serious accidents such as the falling of the suspended object. Therefore, by setting an anti-unhooking device on the hook, the sliding range of the wire rope can be limited to prevent it from falling off the hook.

[0003] The patent with announcement number CN205653045U discloses a gantry crane wire rope anti-unhooking device, which belongs to the technical field of safety protection of the hook body of lifting equipment. The patent includes a clip and a fixing mechanism, and also includes a baffle, wherein: the clip is clamped on the neck of the hook; the fixed end of the baffle is fixedly connected by the fixing mechanism and the clip, and the free end rests on the inner side of the hook head of the hook. The patent uses the cooperation of the clip and the baffle, and the clip and the fixing mechanism fix the fixed end of the baffle, and the free end of the baffle rests freely on the inner side of the hook head, which can just prevent the wire rope from unhooking; after the lifting is completed, when the wire rope needs to be taken out, just lift the hook body slightly, and the baffle will be detached from the hook mouth under the action of its own gravity, and the wire rope can be taken out, which is convenient and labor-saving to operate.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] By setting a baffle on the hook and limiting the sliding range of the wire rope with the baffle, the anti-unhooking effect is achieved. However, due to the complex working environment in the mining area, weeds may grow at the edge of the mining area or in the vicinity, especially in areas that have not been fully cleaned or maintained. During the mining process, these weeds may be accidentally rolled into or entangled in the hook. When too much weeds accumulate on the hook, the range of movement of the wire rope will be limited, and unstable phenomena such as bucket jamming and shaking will occur, affecting the working efficiency. In addition, due to the complexity of the mining environment, it may be difficult for workers to reach the hook, so it is not easy to remove the weeds entangled in the hook.

[0006] To this end, the present invention provides an anti-unhooking device for an electric rake wire rope. Summary of the invention

[0021] 2. The anti-unhooking device for the wire rope of an electric rake described in the present invention utilizes a wrap-around scraping mechanism. When a worker finds weeds entangled on the hook, the worker can utilize a traction device to lift the hook body and the rake bucket in a vertical direction, and then drive the push block to move. During the movement of the push block, the pressure plate can push the weeds entangled on the hook body, so that the weeds can be concentrated to the end of the hook body, and with the cooperation of the limit rod 1 and the limit rod 2, the weeds can be dropped from the hook body, thereby avoiding excessive accumulation of weeds on the hook, which in turn limits the range of movement of the wire rope, and causes the rake bucket to become stuck, shake, and other unstable conditions. The phenomenon of this phenomenon is solved, which ensures the working efficiency. Moreover, before the pushing block pushes the weeds, the blade can be driven to extend from the through slot and rotated back and forth, so as to cut the weeds wrapped around the hook body by the blade, so that the tightness of the weeds and the hook body is weakened, making it easier for the pressure plate to push the weeds, thus avoiding the weeds being wrapped around the hook body in a coiled and relatively tight manner, thereby preventing the push block from pushing it to the end of the hook body, and the limit rod 2 from easily pushing the weeds off the hook body, thereby further ensuring the smooth removal of the weeds wrapped around the hook body.

[0045] Specifically, the existing anti-unhooking device for wire ropes is used to set a baffle on the hook and use the baffle to limit the sliding range of the wire rope to achieve the anti-unhooking effect. However, due to the complex working environment of the mining area, weeds may grow on the edge or nearby areas of the mining area, especially in areas that have not been fully cleaned or maintained. During the mining process, these weeds may be accidentally rolled into or entangled on the hook. When the weeds accumulate too much on the hook, the range of movement of the wire rope will be limited, and then the bucket will be stuck, shake, and other unstable phenomena will occur, affecting the working efficiency. In addition, due to the complexity of the mining environment, it may be difficult for workers to reach the hook, so it is not easy to remove the weeds entangled on the hook.

[0046] Therefore, in order to solve the above problem, when the present embodiment is in use, when the worker finds that there are weeds entangled on the hook, the traction device can be used to lift the hook body 1 and the rake bucket in the vertical direction, and then the motor 3 14 is used to drive the gear 2 15 to rotate, so that the slider 13 can slide in the slide groove 10 and move along the inner ring surface of the hook body 1. Since the pressing plate 24 is initially outside the rotating groove 31, it can form an angle with the push block 5. Therefore, during the movement of the push block 5, the pressing plate 24 can push the weeds entangled on the hook body 1. The weeds on the hook body 1 are pushed, and since the hook body 1 is lifted in the vertical direction, the wire rope will also be in the middle of the bottom of the hook body 1, and when the pressing plate 24 contacts the wire rope, it will be blocked by the wire rope, resulting in obstruction of movement. Therefore, when the push block 5 is about to contact the wire rope, the motor 7 23 can be used to drive the pressing plate 24 to rotate, so that the pressing plate 24 is transferred into the rotating groove 31. At this time, the weeds pushed by the push block 5 will be pressed into the rotating groove 31, and since both sides of the push block 5 are inclined surfaces, Therefore, the push block 5 uses the inclined surface on one side to lift the wire rope and pass it through the gap between the wire rope and the hook body 1. After the push block 5 passes the wire rope, the pressure plate 24 moves out of the rotating groove 31 and continues to push the remaining weeds. When the push block 5 moves to the end of the slide groove 10, the weeds gathered at the pressure plate 24 can be hooked up by driving the limit rod 23 to slide and the limit rod 2 to rotate. The weeds are kept away from the hook body 1 and fall off from the end of the limit rod 23, and then the push block 5 is reset to the initial position. Moreover, since the push block 5 is also in contact with the wire rope by its inclined surface when resetting, it will not be unable to reset normally due to the obstruction of the wire rope. Thus, the weeds entangled inside the hook body 1 are cleared, thereby avoiding the situation that the range of movement of the wire rope is limited due to excessive accumulation of weeds on the hook, and the occurrence of unstable phenomena such as the jamming and shaking of the rake bucket, thereby ensuring the working efficiency.

[0047] Although the above method can be used to remove the weeds wrapped around the hook body 1, when the weeds are wrapped around the hook body 1 in a coiled and relatively tight manner, it may be difficult for the pressure plate 24 to push them to the end of the hook body 1, and it is also difficult for the limit rod 23 to push the weeds off the hook body 1, which affects the weed removal effect. Therefore, in order to avoid this situation, before the push block 5 pushes the weeds, the motor 6 22 can be used to drive the connecting rod 1 20 and the connecting rod 21 to rotate, so that the adjusting rod 12 moves downward until the blade 11 extends out of the through slot 25. At the same time, the motor 5 1 8 drives the gear three 19 to rotate reciprocatingly, so that the rack two 17 and the blade 11 rotate reciprocatingly, and the blade 11 can be used to cut the weeds wrapped around the hook body 1, and then the blade 11 is reset to the installation cavity 29. At this time, the tightness of the weeds and the hook body 1 is weakened, thereby avoiding the weeds from being wrapped around the hook body 1 in a winding and relatively tight manner, and then the push block 5 is difficult to push it to the end of the hook body 1, and the limit rod two 3 is not easy to push the weeds off the hook body 1, further ensuring the smooth removal of the weeds wrapped around the hook body 1.

[0048] Working principle: Use the connecting rod 6 to connect with the external traction device, which can be a winch, electric hoist, etc., and then use the motor 7 to drive the limit rod 1 2 and the limit rod 2 3 to rotate, so that the end of the limit rod 2 3 is away from one end of the hook body 1, and then hang one end of the wire rope in the hook body 1, and drive the limit rod 1 2 to rotate again until the end of the limit rod 2 3 contacts one end of the hook body 1, and then connect the other end of the wire rope to the rake bucket, and the traction device can be used to drive the hook body 1, the wire rope, and the rake bucket to move, thereby realizing the movement of the rake bucket. At the same time, under the action of the limit rod 1 2 and the limit rod 2 3, one side of the hook body 1 is closed, thereby avoiding The wire rope may fall off the hook body 1, thereby ensuring the safety of the operation. When the worker finds weeds entangled on the hook, the traction device can be used to lift the hook body 1 and the rake bucket in the vertical direction, and then the motor 3 14 can be used to drive the gear 2 15 to rotate, so that the slider 13 can slide in the slide groove 10 and move along the inner ring surface of the hook body 1. Since the pressure plate 24 is initially outside the rotating groove 31, it can form an angle with the push block 5. Therefore, during the movement of the push block 5, the pressure plate 24 can push the weeds entangled on the hook body 1. In addition, since the hook body 1 is lifted in the vertical direction, the wire rope will also be in the middle of the bottom of the hook body 1. When the pressing plate 24 contacts the wire rope, it will be blocked by the wire rope, resulting in obstruction of movement. Therefore, when the pushing block 5 is about to contact the wire rope, the motor 7 23 can be used to drive the pressing plate 24 to rotate so that the pressing plate 24 is transferred into the rotating groove 31. At this time, the weeds pushed by the pushing block 5 will be pressed into the rotating groove 31. Moreover, since both sides of the pushing block 5 are inclined surfaces, the pushing block 5 uses the inclined surface on one side to lift the wire rope and pass through the gap between the wire rope and the hook body 1. After the pushing block 5 passes the wire rope, the pressing plate 24 is moved out of the rotating groove 31, and the remaining weeds can be pushed. When the pushing block 5 moves to the end of the slide groove 10, the limiting rod 2 3 can be driven to slide. The end of the limit rod 23 is used to hook up the weeds gathered at the pressure plate 24, and the weeds are kept away from the hook body 1 and fall off from the end of the limit rod 23 under the action of the rotation of the limit rod 2 and the sliding of the limit rod 23, and then the push block 5 is reset to the initial position. In addition, since the push block 5 is also in contact with the wire rope by its inclined surface when resetting, it will not be unable to reset normally due to the obstruction of the wire rope. At this point, the weeds entangled on the inner side of the hook body 1 are removed, thereby avoiding the situation that the range of movement of the wire rope is limited due to excessive accumulation of weeds on the hook, and the occurrence of unstable phenomena such as the jamming and shaking of the rake bucket, thereby ensuring the working efficiency.Although the above method can be used to remove the weeds wrapped around the hook body 1, when the weeds are wrapped around the hook body 1 in a coiled and relatively tight manner, it may be difficult for the pressure plate 24 to push them to the end of the hook body 1, and it is also difficult for the limit rod 23 to push the weeds off the hook body 1, which affects the weed removal effect. Therefore, in order to avoid this situation, before the push block 5 pushes the weeds, the motor 6 22 can be used to drive the connecting rod 1 20 and the connecting rod 21 to rotate, so that the adjusting rod 12 moves downward until the blade 11 extends out of the through slot 25. At the same time, the motor 5 1 8 drives the gear 3 19 to rotate back and forth, so that the rack 2 17 and the blade 11 rotate back and forth, and the blade 11 can be used to cut the weeds wrapped around the hook body 1, and then the blade 11 is reset to the installation cavity 29. At this time, the tightness of the weeds and the hook body 1 is weakened, thereby avoiding the weeds from being wrapped around the hook body 1 in a winding and relatively tight manner, and then the push block 5 is difficult to push it to the end of the hook body 1, and the limit rod 2 3 is not easy to push the weeds off the hook body 1, further ensuring the smooth removal of the weeds wrapped around the hook body 1. ;
