Detailed Implementation

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] Please see Figure 1 and Figure 4 A parallel groove clamp removal device includes: a frame 1, a clamping assembly 2, a locking assembly 3, a cutting assembly 4, and a driving assembly 5.

[0021] The clamping assembly 2 is mounted on the frame 1; the locking assembly 3 is mounted on the frame 1, and the clamping assembly 2 is connected to the locking assembly 3; the driving assembly 5 is mounted on the frame 1; the cutting assembly 4 is mounted on the driving assembly 5; the driving assembly 5 drives the locking assembly 3 to move, thereby causing the clamping assembly 2 to clamp the grooved wire clamp 6; the driving assembly 5 drives the cutting assembly 4 to move closer to or away from the grooved wire clamp 6; when it moves closer, the cutting assembly 4 cuts the grooved wire clamp 6. Specifically, the clamping assembly 2 includes a first clamp 21 and a second clamp 22. The first clamp 21 is detachably mounted in the frame 1 by an M3*6 screw, and the second clamp 22 is slidably disposed in the frame 1 and is connected to the locking assembly 3. The first clamp 21 and the second clamp 22 form a clamping cavity 23 that matches the shape of the grooved wire clamp 6. The locking assembly 3 drives the second clamp 22 to move closer to or away from the first clamp 21, thereby clamping or releasing the grooved wire clamp 6. The clamping assembly 2 clamps the grooved wire clamp 6 from the length direction.

[0022] In use, the parallel grooved wire clamp removal device of this utility model is first moved to the position where the parallel grooved wire clamp 6 needs to be cut, and the parallel grooved wire clamp 6 is inserted into the clamping cavity 23. Then, the drive assembly 5 is activated, which drives the locking assembly 3 to move towards the clamping assembly 2. The movement of the locking assembly 3 causes the second clamp 22 to move closer to the first clamp 21, and the clamping cavity 23 becomes smaller, thereby enveloping the parallel grooved wire clamp 6 until the parallel grooved wire clamp 6 is firmly clamped. At the same time, the drive assembly 5 drives the cutting assembly 4 to move closer to the bolt post 61 on the parallel grooved wire clamp 6. Finally, the cutting assembly 4 is activated, and it moves closer to and cuts the bolt post 61. The lower half of the parallel grooved wire clamp 6 automatically falls off due to the cutting of the bolt post 61. After the cutting is completed, the cutting assembly 4 is turned off, and the drive assembly 5 is activated in reverse, moving the cutting assembly 4 away from the parallel grooved wire clamp 6 and returning to the initial position. Finally, manually pull the locking component 3. The locking component 3 moves back to its original position, causing the second clamp 22 to move away from the first clamp 21, removing the upper part of the grooved wire clamp 6 and completing the cutting operation. This device uses the drive component 5 to automatically drive the locking component 3 to lock the clamping component 2, effectively preventing the grooved wire clamp 6 from loosening due to shaking or force on the clamping component 2, increasing the stability of the clamping. Integrating the clamping component 2, the cutting component 4, and the drive component 5 together, the drive component drives the locking component 3 and the cutting component 4 to work, which is convenient for construction personnel to operate and can ensure the stability and accuracy of the cutting process, thereby improving the disassembly efficiency.

[0023] Please see Figure 1 and Figure 2Furthermore, the clamping assembly 2 also includes two sets of symmetrical wire clamp limiting block modules 24. Each wire clamp limiting block module 24 includes a limiting block 241, a guide post 242, and a first spring 243. The frame 1 has a guide hole 13. One end of the guide post 242 passes through the guide hole 13, and the other end is connected to the limiting block 241. One end of the first spring 243 is connected to the frame 1, and the other end is connected to the limiting block 241. The first spring 243 is sleeved on the outer surface of the guide post 242. Preferably, the distance between the two sets of limiting blocks 241 gradually decreases from the insertion opening of the parallel groove wire clamp 6 to its top. When the parallel groove wire clamp 6 is large, the guide post 242 moves along the guide hole 13, compressing the first spring 243. The first spring 243 applies pressure to the limiting block 241, thereby clamping the parallel groove wire clamp 6. This structure can accommodate parallel groove wire clamps 6 of different widths. The clamp limiting block module 24 clamps the parallel groove clamp 6 from the width direction. With the cooperation of the first clamp 21 and the second clamp 22, it clamps the parallel groove clamp 6 from four sides, further preventing the parallel groove clamp 6 from loosening due to shaking or force, and increasing the stability of clamping.

[0024] Please see Figure 1 Furthermore, the cutting assembly 4 includes a first motor 41 and a cutting blade 42. The first motor 41 is mounted on the drive assembly 5, and the cutting blade 42 is mounted on the output end of the first motor 41. Specifically, the cutting assembly 4 also includes a reduction gearbox 43, which is connected to the output end of the first motor 41. The cutting blade 42 is detachably mounted on the reduction gearbox 43 via hexagon socket head cap screws, facilitating replacement of the cutting blade 42 by the operator. Preferably, the first motor 41 is a 775 motor. In use, when the drive assembly 5 moves the cutting assembly 4 to the position to be cut and grooved for the wire clamp 6, the first motor 41 is started. The first motor 41 drives the cutting blade 42 to rotate, using the sharp edge of the cutting blade 42 to cut the bolt post 61. During the cutting process, the operator controls the cutting accuracy and efficiency by adjusting the rotation speed of the first motor 41 and the feed speed of the cutting blade 42. Compared with disassembling the bolt post 61 using manual tools, this improves disassembly efficiency.

[0025] Please see Figure 1 , Figure 3 , Figure 4 and Figure 7Furthermore, the drive assembly 5 includes a second motor 51, a lead screw 52, ​​a slider 53, and a nut 54. The second motor 51 is mounted on the frame 1, the lead screw 52 is connected to the output end of the second motor 51, the nut 54 is threadedly connected to the lead screw 52, ​​and the slider 53 is connected to the nut 54. Specifically, the frame 1 is provided with a support bracket 14, and the second motor 51 is fixedly mounted on the support bracket 14 with M8*10 screws. The frame 1 is also provided with a bearing seat 15, one end of the lead screw 52 is connected to the output end of the second motor 51, and the other end is rotatably mounted in the bearing seat 15.

The slider base 531 is connected to the nut 54, the gantry frame 532 is slidably mounted on the slider base 531, and the first motor 41 is mounted on the gantry frame 532. The slider base 531 has a strip-shaped hole 533, and the gantry frame 532 has a positioning threaded hole 534. A fixing member 535 is slidably disposed within the strip-shaped hole 533, and passes through the positioning threaded hole 534 and the strip-shaped hole 533 to fix the gantry 532 to the slider base 531. Preferably, the fixing member 535 is an M10 bolt. The gantry frame 532 includes a crossbeam 536 and two sets of symmetrically arranged side plates 537. A first motor 41 is mounted on the crossbeam 536. The crossbeam 536 and the side plates 537 are integrally formed, or the side plates 537 are fixedly installed at both ends of the crossbeam 536 by welding. The positioning threaded hole 534 is located at one end of the side plate 537 near the slider base 531. Preferably, the second motor 51 is an M2006 P36 DC brushless geared motor. In use, according to the thickness of the grooved clamp 6, loosen the fixing piece 535 and move it up and down along the strip hole 533 to adjust the cutting blade 42 to a suitable position on the bolt post 61, then tighten the fixing piece 535. Start the second motor 51 and rotate it clockwise, driving the lead screw 52 to rotate. The nut 54 moves on the shaft of the lead screw 52, ​​driving the cutting assembly 4 to move towards the grooved clamp 6. When it approaches the grooved clamp 6, start the first motor 41, and the cutting blade 42 rotates to cut the bolt post 61. After cutting is completed, turn off the first motor 41 and start the second motor 51 to rotate it counterclockwise, moving the cutting assembly 4 away from the grooved clamp 6 back to its original position.

[0026] Please see Figure 1 and Figure 6 Furthermore, the slider base 531 is provided with a groove 538, and the frame 1 is provided with a boss 11 that mates with the groove 538. The slider base 531 slides along the boss 11. When the slider base 531 moves along the boss 11, the groove 538 and the boss 11 engage, ensuring that the slider base 531 does not exceed the predetermined range during movement, thus guaranteeing the stability and accuracy of the slider base 531 during movement. Preferably, a limiting post 16 is provided on the frame 1, and the height of the limiting post 16 is higher than the top inner wall of the groove 538, ensuring that the slider base 531 does not exceed the predetermined range during movement.

[0027] Furthermore, the frame 1 is provided with a weight-reducing groove 12, and a boss 11 is disposed in the weight-reducing groove 12, and the boss 11 is a hollow tube. This structure reduces the weight of the device, making it easier for the operator to hold the device. Preferably, a limiting post 16 is disposed in the weight-reducing groove 12.

[0028] Please see Figure 4 , Figure 5 and Figure 7 Furthermore, the locking assembly 3 includes a sliding rod 31, a connector 32, a contact post 33, and a pull rod 34. The sliding rod 31 is connected to the clamping assembly 2, and one end of the sliding rod 31 is hinged to the connector 32. The other end of the connector 32 is hinged to the contact post 33. The contact post 33 is connected to the pull rod 34. The driving assembly 5 is provided with a contact groove 55, and the top of the contact post 33 is higher than the inner top wall of the contact groove 55. Specifically, the contact post 33 and the pull rod 34 are integrally formed or the contact post 33 and the pull rod 34 are fixedly connected by screws. The end of the pull rod 34 away from the contact post 33 is provided with a hook, and the slider base 531 is provided with a square contact groove 55. In use, the second motor 51 is started to drive the lead screw 52 to rotate and drive the slider base 531 to move axially along the lead screw 52. During the movement, the inner top wall of the contact groove 55 contacts the contact post 33. The contact post 33 rotates, driving the connecting piece 32 to move forward. Thus, the sliding rod 31 moves forward until the second clamp 22 and the first clamp 21 clamp the grooved wire clamp 6. At this time, the locking component 3 automatically locks the clamping component 2 to prevent the grooved wire clamp 6 from loosening due to shaking or force. The top of the contact post 33 is lower than the top of the inner wall of the contact groove 55. After the cutting is completed, the second motor 51 is started in reverse, and the cutting component 4 moves back to the initial position. Hold the hook of the pull rod 34 and pull it down. The contact post 33 rotates, driving the connecting piece 32 to move backward. Thus, the sliding rod 31 moves backward until the second clamp 22 is away from the first clamp 21, releasing the grooved wire clamp 6 and completing the cutting operation.

[0029] Furthermore, the sliding rod 31 includes a first sliding rod 311 and a second sliding rod 312; the first sliding rod 311 is connected to the clamping assembly 2, and the second sliding rod 312 is hinged to one end of the connecting member 32; the end of the second sliding rod 312 near the first sliding rod 311 has a guide hole 314, the first sliding rod 311 is sleeved in the guide hole 314, and the second spring 313 is sleeved on the outside of the first sliding rod 311, with one end abutting against the clamping assembly 2 and the other end abutting against the end of the second sliding rod 312. The first sliding rod 311 sleeved in the guide hole 314 and the second spring 313 can adjust the distance between the second clamp 22 and the first clamp 21, thereby accommodating different specifications of parallel grooved wire clamps 6. The second spring 313 provides a buffering effect when the connecting member 32 moves the sliding rod 31, and also makes it easier to release the parallel grooved wire clamp 6 by pulling the pull rod 34.

[0030] The parallel grooved wire clamp removal device of this utility model is equipped with a locking component 3, a clamping component 2, and a wire clamp limiting block module 24 to prevent the parallel grooved wire clamp 6 from loosening due to shaking or force, thus increasing the stability of the clamping. A screw drive system and a boss 11 for limiting achieve precise movement and cutting operations. It is also equipped with an adjustable first motor 41 speed and cutting blade 42 feed speed to ensure the stability and accuracy of the cutting process and improve disassembly efficiency. The first sliding rod 311 and the second sliding rod 312 are threaded together, allowing adjustment of the distance between the second clamp 22 and the first clamp 21, thus accommodating different specifications of parallel grooved wire clamps 6.
