Description

Technical Field

[0001] The invention relates to the technical field of cable retraction and release, in particular to a cable retraction and release device for electric power engineering construction. Background Art

[0002] Power cables and control cables are generally wound on cable reels, which are used as carriers for transportation, storage and preservation. When in use, the cables are placed on retractable racks, which can be deployed and recovered more quickly, saving manpower and time, and better reducing cable twisting to prevent cable damage.

[0003] For example, a Chinese patent with announcement number CN110482333B discloses a cable retracting and releasing device for electric power engineering construction, comprising a universal wheel, a bracket movably connected to the upper end of the universal wheel, a rocker movably connected to the side of the bracket, a connecting shaft movably connected to the inner side of the bracket, a disc movably connected to the side of the bracket away from the universal wheel, a roller movably connected to the inner side of the disc, a fixed box movably connected to the inside of the roller, and a small gear ring movably connected to the inside of the bracket. In the cable retracting and releasing device for electric power engineering construction, inner teeth are fixedly connected to the inside of a large gear ring, and the inner teeth are movably connected to an end of a clamping block away from a cylinder. When the large gear ring rotates clockwise, the inner teeth will also rotate clockwise, and the inner teeth will not be blocked when passing through the clamping block. When the large gear ring rotates, the clamping block will clamp the tip of the inner teeth to prevent the large gear ring from rotating, thereby achieving the effect of preventing the equipment from rotating.

[0004] However, the cable retracting and releasing device for power engineering construction described above cannot pull the cable to be evenly reeled on the cable drum during the cable reeling process, which will cause the cable to pile up or become loose during the reeling process, which not only affects the neatness of the cable, but also causes the cable to become entangled or knotted during subsequent transportation, storage or use. Secondly, the cable tension cannot be detected during the winding or loosening process to adjust the winding or loosening speed, which will cause the cable to be subjected to uneven tension during the winding process, causing the cable to deform and twist, and even damage the wires inside the cable. In addition, the lack of tension adjustment function will also cause the cable to be too fast or too slow during the loosening process, affecting construction efficiency. Summary of the invention

[0016] Preferably, the cable retracting and releasing device for electric power engineering construction is used for retracting and releasing cables during electric power engineering construction.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the design of the winding roller, reduction motor, gear ring, handle, semi-arc teeth, first transmission column, cable traction mechanism and pressing mechanism, when the cable is wound up, the cable can be first passed through the cable traction mechanism and fixedly connected to the outer surface of the winding roller, and then the reduction motor can be started to drive the first transmission column at one end of the output shaft to drive the winding roller to rotate in the first C-shaped frame, so that the cable can be driven from the cable traction mechanism to pass through the outer surface of the winding roller. In the process of the reduction motor driving the winding roller to rotate through the first transmission column, the reduction motor will also drive the cable traction mechanism to rotate through the first transmission column, so that the cable traction mechanism can be driven to move left and right at one end of the winding roller during the process of winding the cable, and the tension of the cable can be detected during the left and right movement, and when it is detected that the cable tension is too large, it will A signal is sent to the controller, so that the controller controls the reduction motor to automatically reduce the winding speed of the winding roller to avoid excessive stretching or damage of the cable, and through the reciprocating traction action, the cable can be evenly wound on the outer surface of the winding roller until the cable is wound. The staff can push the handle to drive the semi-arc teeth to slide and mesh with the gear ring, and the gear ring is installed at one end of the winding roller, thereby realizing the locking operation of the winding roller. Subsequently, the pressing mechanism can be started to flip and touch the outer surface of the cable wound on the outer surface of the winding roller, so as to keep the cable tightly wound. When the cable needs to be delivered, it only needs to reverse the winding roller of the reduction motor to achieve it, so that the staff can pull the loosened cable out for use, and in the process of reversing the winding roller, the cable traction mechanism will also be driven to retreat in the opposite direction to reciprocate horizontally. The cable pulling mechanism can be moved horizontally to the left and right to pull the cable to be evenly wound on the outer surface of the winding roller, which avoids local accumulation or looseness of the cable during the winding process, ensures the neatness of the cable winding, and is conducive to the subsequent storage, transportation and use of the cable. The tension detection during winding can effectively avoid excessive stretching or damage of the cable, extend the service life of the cable, and improve the quality of cable winding. In the whole winding process, the cooperation between the cable pulling mechanism and the reduction motor realizes automatic adjustment of the winding speed, reduces the need for manual intervention, improves work efficiency, and reduces the errors that may be caused by manual operation. By starting the pressing mechanism to flip and touch the outer surface of the cable wound on the outer surface of the winding roller, the cable can be kept tightly wound, which helps prevent it from spreading during subsequent transportation and storage, and further improves the overall quality of the cable winding.

[0018] 2. Through the design of the reciprocating screw rod, the transmission block, the sliding block, the tension sensor, the transmission belt and the second transmission column, when the cable is wound up, the cable can first be passed through the electric tension sensor and fixedly connected to the outer surface of the winding roller, and the transmission wheel in the tension sensor can apply a limiting force to the passed cable to keep it stable during the subsequent traction process, and then the reduction motor is started to drive the first transmission column at one end of the output shaft to drive the winding roller to rotate in the first U-shaped frame, so that the cable can be driven from the tension sensor to pass through and be wound up on the outer surface of the winding roller. In the process of the reduction motor driving the first transmission column to rotate, The transmission belt mounted on the outer surface of the first transmission column drives the second transmission column to rotate together, and the second transmission column is fixedly installed at one end of the reciprocating screw rod, thereby driving the reciprocating screw rod to rotate in the second U-shaped frame together, so that in the process of driving the winding roller to rotate, the transmission block threadedly installed on the outer surface of the reciprocating screw rod thread transmission will move horizontally to the left and right, so that the transmission block can drive the tension sensor fixedly installed on the upper surface to move horizontally to the left and right to pull the cable to be evenly wound on the outer surface of the winding roller, thereby avoiding excessive accumulation or looseness of the cable in a certain place, ensuring the neatness of the cable winding, and facilitating subsequent storage, transportation and use; In the process of left and right lateral movement, the tension sensor will also detect the tension of the cable when it is wound up. If it detects that the cable tension is too large or too small, it will send a signal to the controller to control the reduction motor to automatically reduce or increase the winding or unwinding speed of the winding roller. To prevent over-stretching: When the tension is too large, the controller reduces the winding speed of the winding roller to prevent the cable from being over-stretched. Over-stretching of the cable may change its internal structure, such as causing the wire to become thinner and the insulation layer to be damaged, affecting the electrical performance and service life of the cable; It can also prevent loosening and winding: when the tension is too small, the controller increases the winding speed of the winding roller or adjusts the release speed to prevent the cable from loosening and winding. Loosely wound cables are prone to knotting, entanglement and other problems during subsequent transportation, storage or use.

[0019] 3. Through the design of the support seat, connecting plate, connecting seat, top pressure arc plate and hydraulic rod, the hydraulic rod can be started after the winding roller has wound up or released the cable, so that the hydraulic rod pulls the second docking plate at one end of the piston rod, and the second docking plate is fixedly installed at one end of the connecting plate, thereby driving the connecting plate to flip in the support seat, so that the connecting plate drives the top pressure arc plate rotatably installed in the connecting seat to flip and touch the outer surface of the cable wound on the outer surface of the winding roller, which can keep the cable tightly wound. In the process of the top pressure arc plate touching the outer surface of the winding roller, the top pressure arc plate will automatically flip according to the curvature of the outer surface of the winding roller, so as to increase the fit. This tight pressing can effectively prevent the cable from loosening or spreading during subsequent transportation and storage. BRIEF DESCRIPTION OF THE DRAWINGS

The semi-arc tooth 107 can be pushed by the handle 104 to engage with the gear ring 103.

[0025] Through the meshing of the semi-arc teeth 107 and the gear ring 103, a stopping force can be applied to the winding roller 101 to prevent self-rotation.

[0026] Through the design of the winding roller 101, the reduction motor 102, the gear ring 103, the handle 104, the semi-arc teeth 107, the first transmission column 108, the cable traction mechanism 2 and the pressing mechanism 3, when the cable is wound up, the cable can be first passed through the cable traction mechanism 2 and fixedly connected to the outer surface of the winding roller 101, and then the reduction motor 102 can be started to drive the first transmission column 108 at one end of the output shaft to drive the winding roller 101 to rotate in the first U-shaped frame 1, so as to drive the cable from the cable traction mechanism 2 to pass through and be wound on the outer surface of the winding roller 101. In the process of the reduction motor 102 driving the winding roller 101 to rotate through the first transmission column 108, the cable traction mechanism 2 will be driven to rotate together through the first transmission column 108, so as to be able to drive the cable traction mechanism 2 to move left and right at one end of the winding roller 101 during the process of winding the cable, and the tension of the cable can be detected together during the process of moving left and right, and the cable tension can be detected when the cable tension is detected. When the force is too large, a signal will be sent to the controller, so that the controller controls the reduction motor 102 to automatically reduce the winding speed of the winding roller 101 to avoid excessive stretching or damage of the cable, and through the reciprocating traction action, the cable can be evenly wound on the outer surface of the winding roller 101 until the cable is wound. The staff can push the handle 104 to drive the semi-arc teeth 107 to slide and mesh with the gear ring 103, and the gear ring 103 is installed at one end of the winding roller 101, thereby realizing the locking operation of the winding roller 101, and then the pressing mechanism 3 can be started to flip and touch the outer surface of the cable wound on the outer surface of the winding roller 101, so as to keep the cable tightly wound. When the cable needs to be delivered, it only needs to reverse the winding roller 101 by the reduction motor 102, so that the staff can pull the loosened cable out for use, and in the process of reversing the winding roller 101, the cable traction mechanism 2 will also be driven together to retreat in the opposite direction to reciprocate horizontally; The cable pulling mechanism 2 can be moved horizontally to the left and right to pull the cable line and be evenly wound on the outer surface of the winding roller 101, which avoids local accumulation or looseness of the cable during the winding process, ensures the neatness of the cable winding, and is conducive to the subsequent storage, transportation and use of the cable. The tension detection during winding can effectively avoid excessive stretching or damage of the cable, extend the service life of the cable, and also improve the quality of cable winding. In the whole winding process, the cooperation between the cable pulling mechanism 2 and the reduction motor 102 realizes automatic adjustment of the winding speed, reduces the need for manual intervention, improves work efficiency, and reduces the errors that may be caused by manual operation. By starting the pressing mechanism 3 to flip and touch the outer surface of the cable wound on the outer surface of the winding roller 101, the cable can be kept in a tightly wound state, which helps prevent it from spreading during subsequent transportation and storage, and further improves the overall quality of the cable winding.

[0027] like Figure 6-Figure 7 As shown, the cable traction mechanism 2 includes a reciprocating screw rod 201, which is rotatably installed between the second U-shaped frame 105, and a transmission block 203 is threadedly installed on the outer surface of the reciprocating screw rod 201. A tension sensor 205 is fixedly installed on the upper surface of the transmission block 203, so that the cable will preferentially pass through the tension sensor 205 when being wound on the outer surface of the winding roller 101.

[0028] The other end of the reciprocating screw rod 201 passes through one side of the second U-shaped frame 105 and a second transmission column 207 is fixedly installed on the end thereof. A transmission belt 206 is sleeved on the outer surface of the second transmission column 207. The other end of the transmission belt 206 is sleeved on the outer surface of the first transmission column 108, so that the reciprocating screw rod 201 can rotate together with the rotation of the winding roller 101 through the transmission belt 206.

[0029] A sliding block 204 is fixedly installed on the lower surface of the transmission block 203. The sliding block 204 is slidably installed on the outer surface of the sliding column 202. The sliding column 202 is fixedly installed between the second U-shaped frame 105 and is located at the lower end of the reciprocating screw rod 201, so that the transmission block 203 can be moved horizontally left and right by the reciprocating screw rod 201 through the limit of the sliding column 202, thereby realizing that the transmission block 203 drives the tension sensor 205 to pull the cable evenly to be wound on the winding roller 101.

[0030] The signal transmitting end of the tension sensor 205 is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electrical control end of the reduction motor 102. During the process of retracting and releasing the cable, the tension sensor 205 can monitor the real-time tension of the cable, and when it detects that the cable tension is too large, it will send a signal to the controller, so that the controller controls the reduction motor 102 to automatically reduce the retraction and release speed of the winding roller 101 to avoid excessive stretching or damage to the cable.

[0031] The models of the tension sensor 205 and the controller are Zemic205B and ZemicTensionControlUnit3000 respectively.

[0032] Through the design of the reciprocating screw 201, the transmission block 203, the sliding block 204, the tension sensor 205, the transmission belt 206 and the second transmission column 207, when the cable is wound up, the cable can first be passed through the electric tension sensor 205 and fixedly connected to the outer surface of the winding roller 101, and the transmission wheel in the tension sensor 205 can apply a limiting force to the passed cable to keep it stable during the subsequent traction process, and then the reduction motor 102 is started to drive the first transmission column 108 at one end of the output shaft to drive the winding roller 101 to rotate in the first U-shaped frame 1, so that the cable can be driven from the tension sensor 205 to pass through the outer surface of the winding roller 101, and the reduction motor 102 drives the first transmission column 108 to rotate. In the process of driving the winding roller 101 to rotate, the transmission block 203 threadedly mounted on the threaded outer surface of the reciprocating screw 201 can be moved horizontally to the left and right, and the transmission block 203 can drive the tension sensor 205 fixedly mounted on the upper surface to move horizontally to the left and right to pull the cable to be evenly wound on the outer surface of the winding roller 101, thereby avoiding excessive accumulation or loosening of the cable at a certain place, ensuring the neatness of the cable winding, and facilitating the subsequent storage, transportation and use; In the process of left and right lateral movement, the tension sensor 205 will also detect the tension of the cable when it is wound up, and when it detects that the cable tension is too large or too small, it will send a signal to the controller to control the reduction motor 102 to automatically reduce or increase the winding or unwinding speed of the winding roller 101; To prevent the cable from being overstretched: When the tension is too large, the controller reduces the winding speed of the winding roller 101 to prevent the cable from being overstretched. Overstretching the cable may change its internal structure, such as causing the wire to become thinner and the insulation layer to be damaged, thus affecting the electrical performance and service life of the cable; It can also prevent loose winding: when the tension is too small, the controller increases the winding speed of the winding roller 101 or adjusts the loosening speed to prevent the cable from loosening and winding. Loosely wound cables are prone to knotting, entanglement and other problems during subsequent transportation, storage or use.

[0035] Through the design of the support seat 302, the connecting plate 303, the connecting seat 307, the top pressure arc plate 308 and the hydraulic rod 305, the hydraulic rod 305 can be started after the winding roller 101 has wound up or released the cable, so that the hydraulic rod 305 pulls the second docking plate 306 at one end of the piston rod, and the second docking plate 306 is fixedly installed at one end of the connecting plate 303, thereby driving the connecting plate 303 to flip in the support seat 302, so that the connecting plate 303 drives the top pressure arc plate 308 rotatably installed in the connecting seat 307 to flip and touch the outer surface of the cable wound on the outer surface of the winding roller 101, which can keep the cable in a tightly wound state, and when the top pressure arc plate 308 touches the outer surface of the winding roller 101, the top pressure arc plate 308 will automatically flip according to the curvature of the outer surface of the winding roller 101, so as to increase the fit. This tight pressing can effectively prevent the cable from loosening or spreading during subsequent transportation and storage.

[0036] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when the cable is wound up, the cable can be first passed through the electric tension sensor 205 and fixedly connected to the outer surface of the winding roller 101, and the transmission wheel in the tension sensor 205 can apply a limiting force to the passed cable to keep it stable during the subsequent traction process, and then the reduction motor 102 is started to drive the first transmission column 108 at one end of the output shaft to drive the winding roller 101 to rotate in the first U-shaped frame 1, so that the cable can be driven from the tension sensor 205 to pass through the outer surface of the winding roller 101, and the reduction motor 102 drives the first transmission column 108 to rotate, which will cause the transmission belt mounted on the outer surface of the first transmission column 108 to drive. 206 drives the second transmission column 207 to rotate together, and the second transmission column 207 is fixedly installed at one end of the reciprocating screw 201, so that the reciprocating screw 201 can be driven to rotate in the second U-shaped frame 105 together, so that in the process of driving the winding roller 101 to rotate, the transmission block 203 threadedly installed on the outer surface of the reciprocating screw 201 thread transmission can be moved horizontally to the left and right, so that the transmission block 203 can drive the tension sensor 205 fixedly installed on the upper surface to move horizontally to the left and right to pull the cable to be evenly wound on the outer surface of the winding roller 101, and in the process of moving horizontally to the left and right, the tension sensor 205 can also detect the tension of the cable when it is wound, and send a signal to the controller when it detects that the cable tension is too large or too small, so that the controller The controller controls the reduction motor 102 to automatically reduce or increase the winding or releasing speed of the winding roller 101, until the cable is wound up and the staff can push the handle 104 to drive the semi-arc teeth 107 to slide and mesh with the gear ring 103, and the gear ring 103 is installed at one end of the winding roller 101, thereby realizing the locking operation of the winding roller 101, and then the hydraulic rod 305 can be started to make the hydraulic rod 305 pull the second docking plate 306 at one end of the piston rod, and the second docking plate 306 is fixedly installed at one end of the connecting plate 303, thereby driving the connecting plate 303 to flip in the support seat 302, so that the connecting plate 303 drives the top pressure arc plate 308 rotatably installed in the connecting seat 307 to flip and touch the cable wound on the outer surface of the winding roller 101. The outer surface of the cable can keep the cable in a tightly wound state, and when the top pressure arc plate 308 touches the outer surface of the winding roller 101, the top pressure arc plate 308 will automatically flip according to the curvature of the outer surface of the winding roller 101, so as to increase the fit. This tight pressing can effectively prevent the cable from loosening or spreading during subsequent transportation and storage. When the cable needs to be delivered, it only needs to reverse the winding roller 101 by the reduction motor 102, so that the staff can pull the loosened cable out for use, and in the process of reversing the winding roller 101, the reciprocating screw rod 201 will be driven to rotate in the opposite direction, and the tension sensor 205 will be driven to retreat together for reciprocating lateral movement, so that the cable can be pulled out according to the winding path.

[0037] In summary: during the process of winding or releasing the cable, the cable can be pulled to be evenly wound on the outer surface of the winding roller 101, and will be released along the opposite path, which avoids local accumulation or loosening of the cable during the winding process, ensures the neatness of the cable winding, and also detects the tension of the cable during the winding process, and when it detects that the cable tension is too large or too small, it will send a signal to the controller, so that the controller controls the reduction motor 102 to automatically reduce or increase the winding speed of the winding roller 101, so as to avoid excessive stretching or damage of the cable.
