DETAILED DESCRIPTION

[0039] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] like Figure 1 to Figure 6As shown, this embodiment proposes a low-voltage pay-off tension control device, including: a driving member 2 is arranged on a bracket 1; a magnetic powder clutch 3 is arranged on the bracket 1, the magnetic powder clutch 3 has an input end 310 and an output end 320, and the driving member 2 is connected to the input end 310; a fixing member 4 is rotatably arranged on the bracket 1, the fixing member 4 is connected to the output end 320, and the fixing member 4 is used to fix the coil.

[0041] In this embodiment, the specific working principle is as follows: the driving member 2 generates a rotation output to the input end 310 of the magnetic powder clutch 3. The magnetic powder clutch 3 uses the electromagnetic principle and the magnetic powder therein to transmit power at the output end 320. The torque in the magnetic powder clutch 3 is only controlled by the current. Therefore, by controlling the current, the torque can always be controlled at a suitable size. The torque output by the magnetic powder clutch 3 will drive the fixing member 4 to rotate, and the coil on the fixing member 4 will be driven synchronously. One way to use the fixing member 4 is that the fixing member 4 fixes the coil in the form of a turntable and a tightening member, and the tightening member can be moved by a thread or other forms. Another way to use the fixing member 4 is that the fixing member 4 clamps the coil internally in the form of a variable diameter shaft.

[0042] In this embodiment, the motor and the reducer 442 are the driving part 2, which saves manpower and improves work efficiency. At the same time, they are reliable and durable, and also increase the stability and service life of the device. The magnetic powder clutch 3 is a tool for controlling torque. It has a fast response speed, a simple structure, no pollution to the environment, and no noise. At the same time, it consumes less energy than other control devices. The fixing part 4 firmly fixes the coil to prevent the coil from slipping, ensures that the coil can rotate synchronously, and enhances the stability of the device.

[0043] Furthermore, the fixing member 4 includes: a support seat 410 arranged on the output end 320; a transmission shaft 420 arranged on the support seat 410; a plurality of supporting circular members 430, which are arranged on the support seat 410 for rotation at circumferential intervals; a driving assembly 440 arranged on the transmission shaft 420, and the driving assembly 440 is used to drive the supporting circular members 430 to rotate.

[0044] In this embodiment, the driving assembly 440 provides the power required for the rotation of the circular support member 430. The circular support member 430 is arranged in a circular array. The circular support member 430 passes through the coil to fix the coil, so that the coil cannot slide relative to the support base 410, thereby ensuring that the coil is stably driven to rotate. When the construction workers are laying the line, the tension of the copper wire remains stable, which improves the quality and efficiency of laying the line, and also prevents the waste of copper wire caused by the disorder of the copper wire coils.

[0045] Furthermore, the supporting round member 430 is an eccentric shaft.

[0046] In this embodiment, the circular support member 430 rotates on the support seat 410. Since the circular support member 430 is an eccentric shaft, the diameter of the coil that can be carried by the eccentric shaft arranged at circumferential intervals will increase synchronously during rotation, thereby adapting to the installation of coils of different specifications and expanding the application range of the device. At the same time, the eccentric shaft can be rotated before the coil is installed to reduce the diameter, so that the coil is more convenient and quick to install. After the coil is placed in the circular support member 430, the eccentric shaft is rotated by the driving member 2 to firmly clamp the coil, thereby speeding up the replacement speed of the coil and improving the work efficiency.

[0047] Furthermore, the driving assembly 440 includes: an active member 441 disposed on the support base 410; a reducer 442 disposed on the support base 410, the active member 441 is used to drive the reducer 442 to rotate; a transmission member 443 is disposed on the reducer 442, and the transmission member 443 is used to transmit the rotation of the reducer 442.

[0048] In this embodiment, the active component 441 is also a motor. The rotation of the motor is stable. Since the coil is made of copper wire, the overall weight is heavy. The use of a motor avoids manpower consumption, saves costs, and is more convenient to operate. While reducing speed, the reducer 442 can also avoid the problem of the copper wire being too heavy to lift, thereby improving work efficiency.

[0049] Furthermore, the supporting round member 430 is made of elastic material.

[0050] In this embodiment, the round support member 430 has a certain elasticity. Appropriate elasticity can enable the round support member 430 to clamp the inner wall of the coil more firmly when rotating, so that the coil is fixed more stably, thereby improving the stability and safety of the equipment.

[0051] Furthermore, the round supporting member 430 has anti-slip grooves 431 .

[0052] In this embodiment, the anti-skid pattern 431 is provided on the outer wall of the supporting round member 430. The existence of the anti-skid pattern 431 prevents the coil from sliding around when being fixed, and makes it tighter after being fixed, thereby preventing the coil from slipping or falling off and improving safety.

[0053] Furthermore, it also includes: a clamping member 5, which is rotatably arranged on the support seat 410, and the clamping member 5 is used to clamp the coil.

[0054] In this embodiment, the locking member 5 is used to prevent the coil from sliding horizontally along the supporting round member 430 while rotating due to the offset of the placement of the equipment after the coil is fixed, thereby causing the angle of the conveyed line to be offset and affecting the laying quality. At the same time, it can also prevent the coil from slipping off the supporting round member 430, causing danger or unnecessary workload, thereby improving the efficiency of line transportation.

[0055] Furthermore, the support seat 410 has threads, and the locking member 5 also includes:

[0056] A shaft sleeve 510, the shaft sleeve 510 and the support seat 410 are threadedly matched, and the shaft sleeve 510 has a threaded hole 511;

[0057] The threaded rod 520 is disposed on the shaft sleeve 510 . The threaded rod 520 cooperates with the threaded hole 511 on the shaft sleeve 510 . The threaded rod 520 is used to clamp the coil.

[0058] In this embodiment, the sleeve 510 can rotate relative to the thread on the support seat 410, and the threaded rod 520 is installed on the sleeve 510 to support the side wall of the coil clamped by the supporting round member 430. At the same time, the locking member 5 will also rotate synchronously when the coil rotates, and will not change the locking position, so that the coil is fixed more stably. At the same time, since the threaded rod 520 is threadedly connected to the sleeve 510, when the coil is to be removed, the threaded rod 520 can be removed first, and the removal and installation of the coil will not be affected after the removal is completed.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
