[0020] A specific embodiment of the present invention is as Figures 1-4As shown in the figure, a clamping device for steel strand cutting is disclosed, including: two oppositely arranged brackets 10; a limiting rod 20, with both ends of the limiting rod 20 connected to the two brackets 10 respectively. The limiting rod 20 includes at least three. The three limiting rods 20 and the two brackets 10 cooperate to form a clamping space 22 for placing the steel strand coil 21. The brackets 10 are located at both ends of the steel strand coil 21, and the limiting rod 20 is located on the side of the steel strand coil 21 and abuts against the side of the steel strand coil. At least one limiting rod 20 is arranged on both sides below the steel strand coil 21, and at least two limiting rods 20 support the steel strand coil 21 upward; Among them, the limiting rod 20 can move on the bracket 10 so that the limiting rod 20 approaches or moves away from the steel strand coil 21.

[0021] When it is necessary to adapt to steel strand coils 21 of different sizes, the operator moves the position of the limiting rod 20 on the bracket 10 to expand or contract the clamping space 22. Place the steel strand coil 21 into the clamping space 22, and adjust the limiting rod 20 to closely abut against the side of the steel strand coil 21 to form a stable support structure, ensuring that the steel strand coil 21 maintains a fixed posture during the cutting process. Through the adjustable multi-limiting rod 20 clamping structure, the adaptive fixation of steel strand coils 21 with different diameters is realized, avoiding the shaking or slipping of the coil body during cutting, and improving the construction safety and efficiency.

[0022] The bracket 10 has four extension sections, and long strip-shaped holes 23 are opened on the extension sections. The length direction of the long strip-shaped holes 23 points to the axis of the steel strand coil 21. The end of the limiting rod 20 is inserted into the long strip-shaped holes 23, and fastening nuts are arranged at both ends of the long strip-shaped holes 23 for the limiting rod 20.

[0023] Through the combined structure of the long strip-shaped holes 23 and the fastening nuts, the adjustment and rigid locking of the position of the limiting rod 20 are realized, improving the adaptability and clamping stability of the device to steel strand coils 21 with different diameters.

[0024] When it is necessary to adjust the size of the clamping space 22, the operator loosens the fastening nuts at both ends of the limiting rod 20 to enable the limiting rod 20 to slide freely in the long strip-shaped holes 23 of the extension section of the bracket 10. The length direction of the long strip-shaped holes 23 is consistent with the radial direction of the steel strand coil 21, ensuring that the moving track of the limiting rod 20 matches the changing direction of the coil diameter. After adjusting the limiting rod 20 to closely abut against the side of the steel strand coil 21, tighten the fastening nuts, and use the pre-tightening force of the thread pair to rigidly lock the limiting rod 20 on the bracket 10 to form a stable support frame, effectively resisting the rotational torque and lateral force of the steel strand coil 21 during the cutting process.

[0025] The bracket 10 is provided with a wire outlet hole 11 at a position corresponding to the axis of the steel strand coil 21. The precise alignment design of the wire outlet hole 11 and the axis of the steel strand coil 21 guides the steel strand to be discharged smoothly along a straight line, reduces the resistance to discharge and the risk of entanglement, and improves the construction accuracy. After the steel strand coil 21 is placed in the clamping space 22, the wire outlet hole 11 on the bracket 10 is aligned with the central axis of the coil body. When the steel strand is pulled for discharge, the wire passes through the axis of the coil body and passes through the wire outlet hole 11. Alternatively, multiple steel bars may be welded to the bracket 10, and the steel bars as a whole extend outward from the steel strand coil 21, and the multiple steel bars after extension are gathered together, and circular rings are welded at the ends of the multiple steel bars, and the circular rings form the wire outlet hole 11.

[0026] In some embodiments, it also includes a carrying body 30, the bracket 10 is arranged on the carrying body 30, the bottom of the carrying body 30 is provided with walking wheels, the peripheral side of the carrying body 30 is provided with a fastening plug, the carrying body 30 is fastened and inserted, and a locking nut is provided on the fastening support.

[0027] The coordinated design of the traveling wheels and the fastening ground plugs enables the device to have both mobility and working stability, adapting to the needs of rapid deployment in multiple areas of the construction site.

[0028] The operator loosens the locking nut to retract the fastened ground plug upward and away from the ground. At this time, the center of gravity of the device falls on the bottom walking wheel and can be easily moved to the target position by manpower or mechanical traction.

[0029] After the device is positioned, tighten the locking nut and push the fastening plug downward into the ground. The conical structure at the tip of the fastening plug cuts into the soil or hard ground, providing strong anti-slip resistance. At the same time, the walking wheel is slightly lifted off the ground due to the bearing body 30, avoiding displacement during the working process and ensuring that the device maintains a stable posture when the steel strand is unloaded.

[0030] In some embodiments, it also includes: A loading platform 40 is disposed between two brackets 10; The roller mechanism 41 is arranged on the bearing body 30 and is used to drive the loading platform 40 to move; A lifting platform 42 is provided at one end of the loading platform 40 and is used to place the steel strand coil 21 and control the lifting of the steel strand coil 21; The loading platform 40 can move to one end of the carrying body 30 , and continue to move so that one end of the loading platform 40 moves obliquely to the ground.

[0031] The linkage system of the feeding platform 40, the roller mechanism 41 and the lifting platform 42 realizes the automatic feeding and precise positioning of the steel strand coil 21, greatly reducing the intensity of manual handling and the risk of operation.

[0032] The roller mechanism 41 drives the loading platform 40 to move along the length direction of the carrying body 30 until the front end of the platform extends to the ground to form an inclined ramp; The steel strand coil 21 is pushed into the loading platform 40 manually or by a pushing device, and finally placed on the placement platform. After entering, the user presses the other end of the loading platform 40, or presses the other end of the loading platform 40 by a pushing device, so that the loading platform 40 is connected to the roller mechanism 41. The roller mechanism 41 drives the loading platform 40 in reverse to reset, and the steel strand coil 21 is accurately transported between the two brackets 10. The lifting platform 42 steadily lifts the steel strand coil 21 to the same height as the clamping space 22, and then the limit rod 20 adjusts and clamps the steel strand coil 21 to complete the loading process.

[0033] The roller mechanism 41 includes a plurality of rotating rollers 401 arranged at intervals. The plurality of rotating rollers 401 are arranged along the length direction of the carrier body 30 and are rotatably connected to the top surface of the carrier body 30. The rotating rollers 401 are driven by a rotating motor, and the rotating motor is disposed on the carrier platform.

[0034] The roller mechanism 41 realizes the automatic resetting and transportation of the steel strand coil 21 through the friction transmission between the rotating roller 401 and the feeding platform 40, thereby reducing manual intervention and improving the feeding efficiency.

[0035] After the steel strand coil 21 is placed on the loading platform 40 manually or by a pushing device, the user presses the tilted end of the loading platform 40 (or applies pressure by a pushing device) to make the bottom surface of the loading platform 40 closely contact with the rotating roller 401 of the roller mechanism 41. The rotating motor of the roller mechanism 41 drives the rotating roller 401 to rotate, and uses the friction between the roller surface and the bottom surface of the platform to reversely drive the loading platform 40 to move toward the bearing body 30, and accurately transport the steel strand coil 21 to the predetermined position between the two brackets 10, providing a basis for subsequent clamping and fixing.

[0036] The lifting platform 42 includes a fixed main board 421, a movable main board 422, a lifting motor, and a pad 423. The fixed main board 421 is connected to the loading platform 40. The fixed main board 421 is laid flat on the loading platform 40 with a gap between them. The movable main board 422 is arranged in a movable opening opened in the fixed main board 421. The movable main board 422 is an inwardly concave arc structure. The lifting motor is arranged in the gap between the fixed main board 421 and the loading platform 40. The lifting motor is driven and connected to the movable main board 422. Pad grooves are opened on the fixed main board 421 on both sides of the movable main board 422, and two pad grooves are provided on each side. The pad 423 is placed in the pad groove, and the pad 423 can be removed.

[0037] After the feeding platform 40 transports the steel strand coil 21 between the brackets 10, the lifting motor of the lifting platform 42 starts, driving the movable main board 422 to move upward from the movable opening of the fixed main board 421. The concave arc structure of the movable main board 422 fits the outer contour of the steel strand coil 21, applying a uniform lifting force to smoothly lift the coil body to a position equal in height to the clamping space 22 of the brackets 10. At this time, the limit rod 20 can move along the long strip-shaped hole 23 of the extension section of the bracket 10 to quickly adjust and clamp the steel strand coil 21, completing the height matching and positioning in the feeding process.

[0038] The setting of the cushion block 423 can fix the steel strand coil 21. Since the cushion block 423 is detachable, it is very convenient to take. Magnets can also be arranged at the bottom of the cushion block 423 and in the cushion groove to further improve the joint effect. At the same time, the setting of the cushion groove prevents the cushion block 423 from moving horizontally.

[0039] In some embodiments, a counterweight 50 is provided at one end of the feeding platform 40. A connecting track 51 is also provided between the two brackets 10. The connecting track 51 is connected to the brackets 10. A sliding seat 52 is slidably connected to the connecting track 51. The bottom of the sliding seat 52 is connected to a lifting workbench 53. A rotating table 54 is connected to the lifting workbench 53. A locking member 55 is connected to the rotating table 54. The locking member 55 can be detachably connected to the counterweight 50. The counterweight 50 is movably arranged on the feeding platform 40. A weight sensor is provided on the bottom surface of the bracket 10.

[0040] The rotating table 54 includes a rotating outer shell, a built-in motor, and a rotating end. The rotating end is rotatably connected to one end of the rotating outer shell. The rotating outer shell is a cylindrical structure. The built-in motor is arranged inside the rotating outer shell, and the built-in motor is drivingly connected to the rotating end through gears, and the rotating end can rotate.

[0041] The lifting workbench 53 includes a lifting work motor.

[0042] After the steel strand coil 21 enters between the brackets 10, as the steel strand of the steel strand coil 21 continuously exits, the forces on the two brackets 10 become unbalanced. The weight sensor on the bottom surface of the bracket 10 real-time detects the force on the bracket 10 and transmits the data to the control computer. According to the force condition of the bracket 10, the sliding seat 52 is driven to move along the connecting track 51 to the counterweight area of the feeding platform 40. The lifting workbench 53 descends, so that the locking member 55 is inserted into the strip-shaped hole 56 of the counterweight 50 (the counterweight plate 501 in the material frame 502). The locking member 55 is rotated so that the locking bar 552 is clamped below the counterweight plate 501. By moving the sliding seat 52 to the end of the bracket 10 with less force, and at the same time monitoring the force data, when the forces on both ends of the bracket 10 are the same, the counterweight 50 is in a balanced position matching the weight of the steel strand coil 21, using the lever principle to offset the offset moment and ensure the stability of the device.

[0043] The counterweight 50 includes a material frame 502 and a plurality of counterweight plates 501. The plurality of counterweight plates 501 are stacked inside the material frame 502. An isolation platform is provided on the bottom surface of the counterweight plate 501. There is a gap between two adjacent counterweight plates 501 after stacking. A strip-shaped hole 56 is opened at the center of the counterweight plate 501. The locking member 55 includes a locking rod 551 and a plurality of locking strips 552 arranged at intervals. The locking rod 551 can drive the locking strips 552 to insert into the strip-shaped hole 56 and move below the counterweight plate 501. The plurality of locking strips 552 are arranged in parallel.

[0044] According to the weight of the steel strand coil 21 fed back by the weight sensor, the operator can adjust the total counterweight by increasing or decreasing the number of counterweight plates 501 in the material frame 502 (the counterweight plates 501 are stacked through the isolation platform, which is convenient for disassembly and assembly). After adjustment, the locking rod 551 of the locking member 55 drives the locking strips 552 to insert into the strip-shaped hole 56 at the center of the counterweight plate 501, and rotates the locking rod 551 to make the locking strips 552 move horizontally below the counterweight plate 501. The counterweight 50 is rigidly fixed to the sliding seat 52 by using the hooking force between the locking strips 552 and the bottom surface of the counterweight plate 501. This structure ensures that the counterweight 50 does not slide during the movement or loading process of the device, effectively balancing the load of the loading platform 40.

[0045] The weight sensors (such as strain type weighing sensors) on the bottom surface of the brackets 10 continuously collect the vertical load data of the two side brackets 10, convert the physical signals into electrical signals and then transmit them to the control computer. When the steel strand coil 21 pays out wire and causes the force balance of the two side brackets 10 to be disrupted (such as a decrease in the load on one side), the sensor converts the analog signal into a digital signal through an analog-to-digital converter (ADC), triggering the balance adjustment program of the control computer. The control computer calculates the target position of the counterweight 50 according to the force difference, and drives the sliding seat 52 to move along the connecting track 51 (such as a linear guide rail) to the side of the bracket 10 with less force. The sliding seat 52 realizes displacement through a servo motor and a ball screw pair. The sliding seat 52 is internally provided with a servo motor, and the servo motor drives the sliding seat 52 to move.

[0046] The operator adjusts the total counterweight by increasing or decreasing the number of counterweight plates 501 in the material frame 502 according to the type and real-time weight of the steel strand coil 21 fed back by the weight sensor, improving the adaptability of the counterweight. The counterweight plates 501 are stacked through the isolation platform on the bottom surface, forming a gap for easy disassembly and assembly.

[0047] After the sliding seat 52 moves above the counterweight 50, the lifting workbench 53 drives the rotating platform 54 to descend, so that the locking rod 551 of the locking member 55 aligns with the strip-shaped hole 56 at the center of the counterweight plate 501. The built-in motor of the rotating platform 54 drives the rotating end to rotate, drives the locking rod 551 to rotate through gear transmission, makes the locking strips 552 insert into the strip-shaped hole 56, and after rotating again, the locking strips 552 are connected to the counterweight plate 501. The locking strips 552 form a hooking structure with the bottom surface of the counterweight plate 501, rigidly fixing the counterweight 50 to the sliding seat 52.

[0048] A transfer roller is rotatably connected to the loading platform 40. A transfer telescopic motor 57 is provided at one end of the loading platform 40. The transfer telescopic motor 57 is drivingly connected to the material box 502. By means of the transfer telescopic motor 57, the counterweight 50 can slide on the loading platform 40, and the counterweight 50 is controlled to move to the middle of the loading platform 40 and close to the lifting platform 42, so that the loading platform 40 moves and is easily tilted to the ground. After the steel strand coil 21 moves to the lifting platform 42, the counterweight 50 is controlled to move to the end away from the lifting platform 42, so that the counterweight 50 and the steel strand coil 21 form a lever with one end of the bearing body 30 as the fulcrum. At this time, the counterweight 50 helps to offset the gravity of the steel strand coil 21 and helps the tilted end of the loading platform 40 to fall back onto the bearing body 30 again.

[0049] The above specific embodiments have further detailed the purpose, technical solution and beneficial effects of the present application. It should be understood that the above are only specific embodiments of the present application and are not used to limit the protection scope of the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
