Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically to a high-efficiency cutting tool for dismantling old bridge suspension cables. Background Technology

[0002] In the dismantling of old bridge suspension cables, it is necessary to cut and dismantle the cables. Traditional cutting methods usually involve directly using cutting equipment (such as abrasive saws, hydraulic cutters, etc.) to cut the cables. However, the cables have been bearing the bridge load for a long time and have large internal stress. The stress release at the moment of cutting can easily cause the cut end to spring open at high speed, which may cause personal injury or equipment damage. During the cutting process, the cables are prone to shaking, which affects the cutting accuracy and efficiency. Operators need to work at close range, which poses a high safety risk. Traditional tools lack effective restraint on the cut end of the cable, cannot actively eliminate the safety hazards caused by stress release, and require additional protective measures, which increases construction costs and complexity. Utility Model Content

[0003] In view of the problems existing in the high-efficiency cutting tools for dismantling old bridge suspension cables, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide an efficient cutting tool for dismantling old bridge suspension cables, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency cutting tool for dismantling old bridge suspension cables includes a first U-shaped plate and a second U-shaped plate. The first U-shaped plate is sleeved on the outside of the second U-shaped plate. A rotating rod is rotatably mounted on the inside of the second U-shaped plate. A cutting disc is fixedly sleeved on the wall of the rotating rod. A first motor is fixedly mounted on one outer wall of the second U-shaped plate. The output end of the first motor is fixedly connected to one end of the rotating rod. A transmission mechanism for moving the second U-shaped plate is provided in the middle of the first U-shaped plate. A first U-shaped block is fixedly mounted at both ends of the first U-shaped plate. A second U-shaped block is mounted on the side of the first U-shaped block away from the first U-shaped plate. Insertion holes are opened at both ends of the side of the first U-shaped block closer to the second U-shaped block. Both ends of the second U-shaped block are inserted into the corresponding insertion holes. Adjustment mechanisms for driving the relative movement of the first U-shaped block and the second U-shaped block are provided on both sides of the first U-shaped block and the second U-shaped block.

[0007] Preferably, the transmission mechanism includes a worm gear and a worm. A U-shaped seat is fixedly provided on the inner wall of the middle end of the first U-shaped plate. The worm is rotatably disposed in the middle of the U-shaped seat. Transmission rods are rotatably disposed on the inner walls of both sides of the U-shaped seat. The worm gear is fixedly sleeved on the rod wall of the transmission rod. The worm is meshed with the two worm gears. A push rod is fixedly sleeved on the rod wall of the transmission rod. A movable frame is fixedly provided on the side of the second U-shaped plate near the U-shaped seat. One end of the push rod extends to the lower side of the movable frame. A round pin is fixedly provided on the side of the push rod near the movable frame. One end of the round pin passes through the movable frame. A second motor is fixedly provided on the outer wall of the first U-shaped plate. The output end of the second motor is fixedly connected to one end of the worm.

[0008] Preferably, the adjusting mechanism includes a bolt and a nut. First connecting blocks are fixedly provided on both sides of the first U-shaped block, and second connecting blocks are fixedly provided on both sides of the second U-shaped block. The bolt is fixedly provided on the side of the second connecting block close to the first connecting block. A through hole is opened on the surface of the first connecting block. One end of the bolt passes through the corresponding through hole. The nut is threaded onto the shank wall of the bolt. The nut abuts against the side of the first connecting block away from the second connecting block.

[0009] Preferably, the inner walls of both the first U-shaped block and the second U-shaped block are fixedly provided with arc-shaped anti-slip plates.

[0010] Preferably, the rod wall of the round pin is fixedly fitted with an anti-detachment ring on the side of the movable frame away from the push rod.

[0011] Preferably, a sliding rod is fixedly provided on both inner walls of the first U-shaped plate, and a limiting strip is movably sleeved on the rod wall of the sliding rod, and one side of the limiting strip is fixedly connected to the second U-shaped plate.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. This utility model, through a clamping structure composed of a first U-shaped block and a second U-shaped block, combined with an arc-shaped anti-slip clamp on the inner wall, can firmly clamp both ends of the sling to be cut before cutting. When the sling is cut, the impact force generated by stress release is offset by the clamping structure, effectively preventing the broken end from springing open. Compared with traditional cutting methods, this greatly reduces the probability of safety accidents and significantly protects the lives of construction personnel and the safety of equipment.

[0014] 2. This utility model adopts a worm gear and worm meshing design in the transmission mechanism. The second motor drives the worm to rotate, and the worm gear drives the transmission rods on both sides to rotate synchronously. The push rod pushes the movable frame to realize the smooth feeding of the second U-shaped plate. The limit strip and the slide bar cooperate to ensure that the cutting disc moves in a straight line, avoiding the problem of skewed cuts caused by shaking in traditional manual operation, and greatly improving efficiency.
