[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

The following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

The words "including" or "comprising" and the like used in the present disclosure mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. The words "connect" or "connected" and the like are not limited to physical or mechanical connections, but may also include electrical connections, whether direct or indirect. "Up", "down", "left", "right", etc. are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0031] like Figure 1-3 As shown: a cable construction clamping device, comprising a frame, an introduction wheel group and an execution component, the frame is fixedly connected to the foundation, the execution component is fixedly connected to the frame, and the introduction wheel group is installed on the execution component;

[0032] The actuator assembly includes a fixed housing 2, a motor 1, a screw rod 3, a screw nut 4 and a carrying platform 5. The fixed housing 2 is fixedly connected to the frame, the motor 1 is fixedly connected to the fixed housing 2, one end of the screw rod 3 is rotatably connected to the fixed housing 2, and the other end of the screw rod 3 is rotatably connected to the frame. The end of the screw rod 3 close to the fixed housing 2 is connected to and transmitted to the output shaft of the motor 1, the screw nut 4 is sleeved on the screw rod 3, the carrying platform 5 is fixedly connected to the screw nut 4, and the introduction wheel group is installed on the carrying platform 5; the power is provided by the output shaft of the motor 1 to drive the screw rod 3 to rotate and the screw nut 4 to move on the screw rod 3, and finally the introduction wheel group follows the screw nut 4 to move up and down.

[0033] The guide wheel assembly includes a clamping base plate 10 and a clamping shell, a plurality of guide wheels are arranged side by side on the clamping base plate 10, the clamping base plate 10 is mounted on the carrying platform 5, the clamping shell is mounted on the frame, and a clamping groove corresponding to the guide wheel is provided on the lower surface of the clamping shell. Since the clamping shell and the clamping base plate 10 are designed as separate bodies, when the clamping base plate 10 moves upward, the guide wheel installed on the clamping base plate 10 gradually approaches the clamping shell, so that the cable is finally clamped between the guide wheel and the clamping groove under the clamping shell.

[0034] During cable construction, the cable is first connected and passed through the guide wheel group, and then the cable is pulled to the laying position; when the cable needs to be clamped, the operator only needs to start the control motor 1, the motor 1 drives the screw 3 to rotate and makes the guide wheel group and the carrying platform 5 move upward along the axial direction of the screw 3 with the screw nut 4, so that the cable on the guide wheel group is clamped between the guide wheel and the clamping shell; when the cable needs to be loosened, the operator can also operate the motor 1 to rotate in the opposite direction to achieve unlocking. The above scheme greatly reduces the work intensity of the staff and improves the work efficiency. The operator can remotely control the whole process to reduce the risks that may be encountered during the construction process.

[0035] Specifically, a rubber layer is provided in the clamping groove, a sawtooth protrusion is provided in the clamping groove, and the direction of the sawtooth protrusion is perpendicular to the axis of the guide wheel, so as to further enhance the anti-slip performance of the clamping groove and improve the stability when clamping the cable.

[0036] Specifically, a slot hole for engaging the guide wheel shaft is provided on the side of the clamping base plate 10, the slot hole is arranged vertically, a support rod is provided on the outside of the slot hole, a spring is provided below the support rod, one end of the spring abuts against the support rod, the other end of the spring abuts against the clamping shell, and the end of the support rod away from the spring abuts against the shaft end of the guide wheel; a first protrusion is provided on the inside of the slot hole, an arc-shaped gear ring is provided on the upper end of the first protrusion, and a gear that cooperates with the arc-shaped gear ring is provided on the guide wheel shaft. When the guide wheel rolls normally for cable guidance, the gear is not in meshing state with the arc-shaped gear ring, and the guide wheel can rotate freely. When the clamping base plate 10 moves upward for clamping, the guide wheel moves downward so that the gear is meshed with the arc-shaped gear ring, and the guide wheel completes self-locking to prevent the rolling of the guide wheel from affecting the stability of the cable when it is clamped.

[0037] Specifically, a clamping rod is further provided in the clamping base plate 10, and the installation position of the clamping rod is lower than the highest position of the guide wheel, and lower than or equal to the lowest position of the guide wheel. When the pressure of the guide wheel when clamped is at the lowest position, the fixed clamping rod also participates in the clamping process, and clamps the cable in cooperation with the clamping groove, thereby increasing the clamping area of ​​the cable and further enhancing the stability of the clamped cable.

[0038] Specifically, a pressure sensor is provided at the bottom of the clamping groove, which can monitor the clamping force of the cable in real time and feed it back to the operator's console, so that the operator can manually operate the motor 1 to rotate or the program can automatically control the motor 1 to rotate, so as to always keep the clamping force of the cable above the standard line, greatly improving the stability of the clamping cable.

[0039] Specifically, a connecting shaft 6, a bearing seat 7 and a load-bearing frame are further provided between the output shaft of the motor 1 and the screw rod 3. The bearing seat 7 is fixedly connected to the fixed housing 2. One end of the connecting shaft 6 is connected to the output shaft of the motor 1, and the other end of the connecting shaft 6 passes through the bearing seat 7 and is connected to the screw rod 3. The shaft section of the connecting shaft 6 between the bearing seat 7 and the screw rod 3 is provided with a second protrusion, and the shaft section below the second protrusion is sleeved with a thrust bearing 8. The other side of the thrust bearing 8 abuts against one end of the load-bearing frame, and the other end of the load-bearing frame is fixedly connected to the foundation. When the falling force on the screw is too large, the falling force can be transmitted to the load-bearing frame through the connecting shaft 6 and the thrust bearing 8, thereby ensuring that the output shaft of the motor 1 is only subjected to a small tensile force, extending the working life of the motor 1 and reducing the failure rate of the motor 1.

[0040] Specifically, it also includes a control end, and the end face of the connecting shaft 6 is provided with a transmission hole for inserting the output shaft of the power supply machine 1, and the motor 1 and the transmission hole are radially provided with a first pin hole; the end of the connecting shaft 6 away from the motor 1 and one end of the connecting sleeve 9 are radially provided with a second pin hole, and the other end of the connecting sleeve 9 and the screw rod 3 are radially provided with a third pin hole, which is simple to connect and easy to process.

[0041] Specifically, to facilitate processing, the first pin hole, the second pin hole and the third pin hole may have the same diameter, which further reduces processing costs.

[0042] Specifically, the cylindrical surface of the guide wheel is radially concave, so that when the cable is pulled and moved on the guide wheel, it can always be at the lowest point of the guide wheel, which can effectively prevent the cable from moving laterally.

[0043] Specifically, the guide wheel is made of rubber, and the cylindrical surface of the guide wheel is provided with anti-slip patterns, which further increases the friction coefficient of the guide wheel surface, increases the friction between the cable and the guide wheel, and further improves the stability when clamping the cable.

[0044] The above is a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes according to the technical solutions and concepts of the present invention, which should be covered by the protection scope of the claims of the present invention.
