Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable clamp technology, specifically to a cable clamp screw fastening device. Background Technology
[0002] Cable clamps are non-slip nodes used to connect cables and related components. They are mainly used to connect the main cable and suspenders of suspension bridges, and their design and construction directly affect the safety and stability of the bridge.
[0003] Traditional cable clamp bolt fastening devices often experience slippage during operation due to contaminants such as oil, moisture, and dust on the bolt surface. This significantly reduces the friction between the fastening tool and the bolt, making slippage highly likely. Slippage not only causes uneven stress on the slings, affecting the stress balance of the bridge structure, but may also lead to insufficient or excessive tightening torque, reducing project quality and even causing safety hazards. Utility Model Content
[0004] In view of the problems existing in the above-mentioned cable clamp screw fastening device, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a cable clamp screw fastening device, which solves the problem that traditional cable clamp screw fastening devices are prone to slippage during operation. Slippage not only causes uneven stress on the slings, affecting the stress balance of the bridge structure, but may also lead to insufficient or excessive tightening torque, reducing project quality and even causing safety hazards.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] The cable clamp screw fastening device includes two cable clamps. Each of the two cable clamps has multiple symmetrically arranged grooves on one side. An arc-shaped clamping block is slidably arranged inside each groove. An anti-slip protrusion is fixedly connected to the inner side of each arc-shaped clamping block. A sliding block is fixedly connected to one side of each arc-shaped clamping block. Two fixing blocks are symmetrically fixedly connected to one side of each of the two cable clamps. Each fixing block has two first cavities inside. An adjustment mechanism is provided on one side of each first cavity. Each sliding block moves through a corresponding adjustment mechanism. A second cavity is provided between the two corresponding first cavities. A driving mechanism is provided on one side of each second cavity. Each adjustment mechanism matches a corresponding driving mechanism. A fixing mechanism is provided between the two cable clamps.
[0008] Preferably, the adjusting mechanism includes multiple lead screws, multiple first bevel gears, and multiple trapezoidal blocks. Each lead screw is rotatably connected to the interior of a corresponding first cavity. Each trapezoidal block is threaded onto the wall of the corresponding lead screw. One end of each lead screw passes through one side of the corresponding first cavity and extends into the interior of the corresponding second cavity. Each first bevel gear is fixedly sleeved onto the wall of the corresponding lead screw.
[0009] Preferably, the driving mechanism includes multiple rotating rods, multiple second bevel gears, multiple rotating plates, and multiple first bolts. Each rotating rod is rotatably connected to the interior of a corresponding second cavity. Each second bevel gear is fixedly sleeved on the rod wall at one end of the corresponding rotating rod and meshes with two corresponding first bevel gears. Each rotating plate is fixedly connected to one end of the corresponding rotating rod. Each rotating plate has two symmetrically formed first mounting holes on its upper surface. Each first bolt is disposed inside the corresponding first mounting hole.
[0010] Preferably, the fixing mechanism includes two fixing plates, and the upper surfaces of the two fixing plates are respectively provided with multiple internal threaded holes, and a second bolt is provided inside each of the two corresponding internal threaded holes.
[0011] Preferably, each of the sliding blocks has an inclined surface at its upper end, and each inclined surface has a T-shaped groove. A T-shaped block is slidably disposed inside each T-shaped groove, and each T-shaped block is fixedly connected to the inclined surface of the corresponding trapezoidal block.
[0012] Preferably, each of the sliding blocks has a limiting groove on both sides, and a limiting block is slidably disposed inside each of the two limiting grooves, with each limiting block being fixedly connected to one side of the corresponding sliding block.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] 1. This utility model uses a serrated structure for the anti-slip protrusions on the inner side of the arc-shaped clamping block, which can be embedded into the gaps on the screw surface. Even if there are contaminants such as oil and dust, it can still form an effective engagement, providing sufficient friction and avoiding problems such as insufficient torque or over-tightening caused by slippage.
[0015] 2. This utility model achieves synchronous movement of multiple arc-shaped clamping blocks through the linkage of a rotating rod, bevel gear, and lead screw, avoiding the cumbersome process of adjusting each clamping block individually in traditional methods. The design of the rotating plate and the first bolt allows for quick locking of the clamping block positions. Combined with the fixing mechanism of the fixed plate and the second bolt, a ring-shaped clamping effect is formed on the screw, significantly shortening the tightening time and improving construction efficiency.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] This utility model discloses a cable clamp screw fastening device.
[0025] This utility model provides, for example Figure 1-3 The cable clamp screw fastening device shown includes two cable clamps 1. Each cable clamp 1 has multiple symmetrically arranged grooves on one side. Each groove has an arc-shaped clamping block 2 slidably arranged inside. Each arc-shaped clamping block 2 has an anti-slip protrusion 15 fixedly connected to its inner side. Each arc-shaped clamping block 2 has a sliding block 3 fixedly connected to one side. Each cable clamp 1 has two fixed blocks 4 symmetrically fixedly connected to one side. Each fixed block 4 has two first cavities inside. Each first cavity has an adjustment mechanism on one side. Each sliding block 3 moves through a corresponding adjustment mechanism. A second cavity is opened between the two corresponding first cavities. Each second cavity has a driving mechanism on one side. Each adjustment mechanism matches a corresponding driving mechanism. A fixing mechanism is provided between the two cable clamps 1.
[0026] Two cable clamps 1 are fixed to the outer surface of the screw. Then, two arc-shaped clamps 2 are moved. The anti-slip protrusions 15 on the inner side of the arc-shaped clamps 2 are designed with serrations. When they come into contact with the screw surface, they form multi-point engagement. Even if there is oil or dust on the screw surface, the protruding teeth can still be embedded in the screw gaps to provide sufficient friction and prevent slippage.
[0027] In order for the two curved clamping blocks 2 to be movable, as Figure 1-4 As shown, the adjusting mechanism includes multiple lead screws 5, multiple first bevel gears 6, and multiple trapezoidal blocks 7. Each lead screw 5 is rotatably connected to the interior of a corresponding first cavity. Each trapezoidal block 7 is threaded onto the wall of the corresponding lead screw 5. One end of each lead screw 5 passes through one side of the corresponding first cavity and extends into the interior of a corresponding second cavity. Each first bevel gear 6 is fixedly sleeved onto the wall of the corresponding lead screw 5. The driving mechanism includes multiple rotating rods 8, multiple second bevel gears 9, multiple rotating plates 10, and multiple first bolts 11. Each rotating rod 8 is rotatably connected to the interior of a corresponding second cavity. Each second bevel gear 9 is fixedly sleeved on the rod wall at one end of the corresponding rotating rod 8 and meshes with the two corresponding first bevel gears 6. Each rotating plate 10 is fixedly connected to one end of the corresponding rotating rod 8. Two first mounting holes are symmetrically opened on the upper surface of each rotating plate 10. Each first bolt 11 is set inside the corresponding first mounting hole. Each sliding block 3 has an inclined surface at its upper end. Each inclined surface has a T-shaped groove. A T-shaped block 14 is slidably arranged inside each T-shaped groove. Each T-shaped block 14 is fixedly connected to the inclined surface of the corresponding trapezoidal block 7.
[0028] Rotate the rotating plate 10 to make the rotating rod 8 rotate. Then, the second bevel gear 9 meshes with the first bevel gears 6 on both sides to make the lead screw 5 rotate synchronously. Since the trapezoidal block 7 is threaded onto the lead screw 5, the rotation of the lead screw drives the trapezoidal block to move along the lead screw axis. Through the T-shaped block 14 cooperating with the T-shaped groove of the sliding block 3, the sliding block 3 and the arc-shaped clamping block 2 are pushed to move in the direction of the screw. Then, the rotating plate 10 can be fixed by each first bolt 11, so that the rotating plate 10 can be fixed.
[0029] To fix the two arc-shaped clamps 2, as follows: Figure 1 As shown, the fixing mechanism includes two fixing plates 12. The upper surfaces of the two fixing plates 12 are respectively provided with multiple internal threaded holes, and the interior of each of the two corresponding internal threaded holes is provided with a second bolt 13.
[0030] The two cable clamps 1 are fixed by the fixing plate 12 and the second bolt 13, forming a ring-shaped clamp on the screw, thereby initially fixing the screw.
[0031] To stabilize slider 3, as follows Figure 1As shown, each sliding block 3 has a limiting groove on both sides, and a limiting block 16 is slidably arranged inside each of the two limiting grooves. Each limiting block 16 is fixedly connected to one side of the corresponding sliding block 3.
[0032] Each limit block 16 can be used to limit the movement of the sliding block 3, thus ensuring its stability.
[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
