At the same time, it can prevent the tensioning device from sliding or tipping over when under force, reduce the risk of equipment damage or personal injury, and extend the service life of the equipment.

[0023] A card slot is provided at the front of the support column 6, and the contacting surfaces of the L-shaped rod 14 and the inclined plane block 12 are both set as inclined planes. A spring 1 is provided between the slider 7 and the support column 6, a spring 2 is provided between the card slot 11 and the fixed rod 10, and a spring 3 is provided between the L-shaped rod 14 and the handrail ring 9.

[0024] During the operation of this embodiment: First, before starting the work, the staff checks whether the working state of the equipment is normal. After the staff confirms that there are no faults or other problems with the equipment, the equipment is moved to the designated working area through the universal wheels 2. In the working area, the wire coil to be laid is placed on the circumferential surface of the first rotating column 5. Subsequently, the wire is passed through the second rotating column 8 to start the wire paying-off work. Before paying off the wire, a certain tension needs to be applied to the wire to avoid the wire being wound or knotted due to slack during the paying-off process, ensuring the smooth progress of the paying-off process. At the same time, it can prevent the wire from rubbing or dragging on the ground or the surface of the equipment, reducing the risk of wear of the wire outer skin or damage to the internal conductor. At this time, the staff needs to manually press the button 13 before starting to pay off the wire, so that the button 13 drives the L-shaped rod 14 to start moving. The L-shaped rod 14 moves into contact with and pushes the first inclined block 12 to start moving forward. The movement of the first inclined block 12 drives the clamping rod 11 to start moving forward. The clamping rod 11 moves out of contact with the first clamping groove opened on the support column 6. Subsequently, the staff manually holds the armrest ring 9 and moves the armrest ring 9 downward to the designated position to ensure that the tension of the wire for the current construction meets the construction requirements. Then the staff releases the button 13. At this time, the L-shaped rod 14 starts to move back under the action of the third spring. The L-shaped rod 14 moves out of contact with the first inclined block 12. Subsequently, the clamping rod 11 starts to move back under the action of the second spring and comes into contact with the clamping groove to limit the movement of the slider 7, preventing it from accidentally moving during the work, avoiding tension fluctuations caused by the displacement of the device, ensuring the quality of wire laying, reducing equipment damage and improving work efficiency. At the same time, it can prevent the tensioning device from sliding or tipping when stressed, reducing the risk of equipment damage or personal injury and extending the service life of the equipment.

[0027] The stabilizing device further includes a pull rod 1510 and a U-shaped rod 1511. The pull rod 1510 is slidably installed inside the bottom plate 1. The U-shaped rod 1511 is fixedly installed at the bottom of the pull rod 1510. Under the continuous movement of the second inclined surface block 155, the U-shaped rod 1511 contacts the second slot opened on the second inclined surface block 155 and restricts the movement of the second inclined surface block 155, ensuring that the contact block 157 always contacts and fixes the fixing disk 159 during operation, avoiding the contact block 157 detaching from the fixing disk 159 during the process of adjusting the tension during operation, resulting in displacement of the device and affecting the operation of the staff, and at the same time ensuring the operation safety of the staff when operating close to the device.

[0028] The surfaces of the first inclined surface rod 153 and the second inclined surface block 155 that are in contact with each other are both set as inclined surfaces. A limiting groove is opened on the back of the second inclined surface block 155.

One end of the connecting rod II 166 is rotatably installed at the bottom of the ratchet pawl 165, and the other end of the connecting rod II 166 is slidably installed at the top of the sliding column 162. The cooperation of the ratchet wheel 164 and the ratchet pawl 165 can prevent the device from accidentally starting when it is not fully prepared, avoiding equipment damage or personal injury caused by misoperation. At the same time, it ensures that the tensioning operation is carried out only after the preparation work is completed, which can avoid excessive stretching or damage of the wire caused by improper operation and guarantee the electrical and mechanical properties of the wire.

[0030] The release device further includes a pressing rod 167, an inclined block IV 168, and a long rod 169. The pressing rod 167 is fixedly installed on the circumferential surface of the sliding column 162. The inclined block IV 168 is slidably installed on the top of the bottom plate 1. The long rod 169 is fixedly installed on the right side of the inclined block IV 168. By moving the long rod 169 to contact the wire coil placed on the circumferential surface of the rotating column I 5 during the preparation process, it can help the operator more easily push the wire to the middle position, reducing the time and physical effort of manual adjustment, thereby improving the wire releasing efficiency. At the same time, it can reduce the chance of the operator directly contacting the wire, reducing the risk of electric shock or being tripped by the wire and improving the operation safety.

[0031] The surfaces of the inclined rod II 161 and the inclined block III 163 that are in contact with each other are both set as inclined surfaces. The surfaces of the pressing rod 167 and the inclined block IV 168 that are in contact with each other are both set as inclined surfaces. A spring V is arranged between the sliding column 162 and the bottom plate 1, and a spring VI is arranged between the inclined block IV 168 and the bottom plate 1. By setting the inclined surfaces, it is ensured that the inclined rod II 161 can smoothly push the inclined block III 163 when moving. By setting the inclined surfaces, it is ensured that the pressing rod 167 can smoothly push the inclined block IV 168 when moving. By setting the spring V, it is ensured that the sliding column 162 can achieve self-resetting. By setting the spring VI, it is ensured that the inclined block IV 168 can achieve self-resetting.

[0032] During the operation of this embodiment: While the staff manually moves the handrail ring 9 downward, the first connecting rod 151 starts to move downward. The movement of the first connecting rod 151 drives the push rod 152 to start moving downward. The movement of the push rod 152 drives the first inclined surface rod 153 to start moving downward. The first inclined surface rod 153 moves to contact and push the second inclined surface block 155 to start moving towards the elastic telescopic rod 154. The movement of the second inclined surface block 155 drives the fixed plate 156 to start moving towards the fixed disk 159. The movement of the fixed plate 156 drives the contact block 157 to start moving towards the fixed disk 159. The contact block 157 moves and gradually contacts the fixed disk 159. Under continuous contact, the fixed disk 159 is clamped and fixed by the contact block 157, which can prevent the device from accidentally moving during operation, ensure that the equipment remains stable during the process of tightening the wire, and the fixed universal wheel 2 can ensure the stable operation of the tightening device, avoid operation difficulties caused by terrain influence. At the same time, by reducing equipment damage and improving work efficiency, the fixed universal wheel 2 can indirectly reduce the construction cost. While the second inclined surface block 155 moves to drive the fixed plate 156 to start moving towards the fixed disk 159, it contacts and pushes the U-shaped rod 1511 to start moving. The movement of the U-shaped rod 1511 drives the pull rod 1510 to start moving. Under the continuous movement of the second inclined surface block 155, the U-shaped rod 1511 contacts and restricts the movement of the second inclined surface block 155 by the second card slot formed on the second inclined surface block 155, ensuring that the contact block 157 always contacts and fixes the fixed disk 159 during operation, avoiding the contact block 157 disengaging from the fixed disk 159 during the process of adjusting the tension during operation, resulting in equipment displacement and affecting the operation of the staff, and at the same time ensuring the operation safety of the staff when operating close to the equipment.

[0033] While the inclined plane block two 155 moves to drive the fixed plate 156 to start moving towards the fixed disk 159, it also drives the inclined plane rod two 161 to start moving. The movement of the inclined plane rod two 161 pushes the inclined plane block three 163 to start moving downward. The movement of the inclined plane block three 163 drives the slide column 162 to start moving downward. The movement of the slide column 162 drives the connecting rod two 166 to start moving downward. The movement of the connecting rod two 166 drives the pawl 165 to start rotating. The rotation of the pawl 165 causes it to disengage from the contact relationship with the ratchet wheel 164 and no longer restricts the rotation of the ratchet wheel 164. After the ratchet wheel 164 and the pawl 165 are disengaged, the motor 4 is started, and the motor 4 drives the rotating column one 5 to start rotating. The rotation of the rotating column one 5 starts the wire paying-out work. The cooperation of the ratchet wheel 164 and the pawl 165 can prevent the device from starting accidentally when it is not fully prepared, avoiding equipment damage or personal injury caused by misoperation. At the same time, it ensures that the tensioning operation is carried out only after the preparation work is completed, which can avoid excessive stretching or damage of the wire due to improper operation and ensure the electrical and mechanical properties of the wire. While the slide column 162 moves downward, it drives the pressure rod 167 to start moving downward. The movement of the pressure rod 167 contacts and pushes the inclined plane block four 168 to start moving. The movement of the inclined plane block four 168 drives the long rod 169 to start moving. The long rod 169 moves to contact the wire coil placed on the circumferential surface of the rotating column one 5 during the preparation process, which can help the operator more easily push the wire towards the middle position, reducing the time and physical effort of manual adjustment, thereby improving the wire paying-out efficiency. At the same time, it can reduce the chance of the operator directly contacting the wire, reducing the risk of electric shock or being tripped by the wire and improving the operation safety.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
