Description

Technical Field

[0001] This invention relates to the field of power construction technology, and in particular to an automatic installation tool for parallel trench clamps. Background Technology

[0002] Parallel groove clamps are used for connecting small- to medium-section aluminum stranded wires or steel-cored aluminum stranded wires, as well as steel stranded wires of overhead lightning protection wires, in positions where they are not subjected to tension. They are also used for jumper connections on non-straight-line towers. Power engineering materials (fittings) for connecting conductors are mainly used in power line engineering. If the reliability of parallel groove clamps is low, power supply companies will need to increase the frequency of inspections, shorten maintenance cycles, and increase operating costs. If parallel groove clamps cause faults or accidents, it can lead to large-scale power outages and threaten the personal safety of urban and rural residents.

[0003] In existing technologies, power departments need to carry out overhead cable paralleling work in an environment without power interruption. When workers are performing live work, they often install two parallel cable clamps at the same time. However, manual operation is not only cumbersome and labor-intensive, but also prone to errors, which can lead to malfunctions or accidents and operational risks, greatly reducing the reliability and safety of parallel cable clamp installation.

[0004] To address this issue, we propose an automatic installation tool for parallel groove clamps. Summary of the Invention

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Reference Figure 1-5 An automatic installation tool for a parallel groove clamp 5 includes a base 1. The base 1 includes a drive module 2, a locking module 3, and a clamping module 4. It should be noted that the drive module 2 includes a battery 21 and an impact wrench 22. The battery 21 and the base 1 are installed and removed. The impact wrench 22 is remotely controlled by a control module to achieve positioning drive.

[0029] The base 1 is equipped with a wire clamp 5 via a locking module 3. It should be noted that the wire clamp 5 includes an upper end plate 51 and a lower end plate 52. The upper end plate 51 and the lower end plate 52 are assembled and disassembled by bolts 53. The upper end plate 51 and the lower end plate 52 are provided with grooves on the side close to each other for clamping the main branch line 6. The output end of the impact wrench 22 is provided with a sleeve 23. The end of the bolt 53 and the groove of the sleeve 23 are connected. Driven by the impact wrench 22, the wire clamp 5 is driven to perform a non-following tightening action.

[0030] Specifically, refer to Figure 4 The locking module 3 includes a first motor 31, a locking block 32, a connecting rod structure 33, and an emergency unlocking rod 34. One end of the locking block 32 is rotatably connected to the base 1, and the other end of the locking block 32 is movably connected to the connecting rod structure 33 via a pull rod 35. The connecting rod structure 33 drives the locking block 32 to perform a locking action via a second motor 41. The lower end plate 52 is provided with a wedge block 54. The locking block 32 and the wedge block 54 cooperate to perform the locking / unlocking action of the wire clamp 5. The emergency unlocking rod 34 is located at the end of the connecting rod structure 33 near the first motor 31 to realize mechanical unlocking after the wire clamp 5 is locked, avoiding the possibility of motor failure in high-altitude and high-voltage environments, which would require mechanical unlocking.

[0031] More specifically, the linkage structure 33 includes a T-shaped rod 331, a guide rod 332, and a swing rod 333. The T-shaped rod 331 is rotatably connected to the base 1. Both ends of the T-shaped rod 331 are rotatably connected to the locking block 32. The bottom of the T-shaped rod 331 is rotatably connected to the swing rod 333 through the guide rod 332. The swing rod 333 is fixedly connected to the output shaft of the motor and the emergency unlocking rod 34 to achieve quick engagement of the wire clamp 5.

[0032] Reference Figure 1 and Figure 5 One side of the clamp 5 can be fitted with a branch line 6 via the clamping module 4, and the other side of the clamp 5 can be fitted with a main line 7 via the clamping module 4. After the clamp 5 grips the main and branch lines 6, it performs a non-following tightening action via the drive module 2, thus realizing the integrated installation operation of the clamp 5 and the cable.

[0033] Specifically, the clamping module 4 includes a second motor 41, a top plate 42, and a push plate 43. The top plate 42 is equipped with a Y-shaped frame to facilitate clamping of the branch line 6. The push plate 43 is equipped with a burr to facilitate gripping of the main line 7. Both the top plate 42 and the push plate 43 are equipped with a loop frame 44. The loop frame 44 slides through a transmission mechanism 45 and a base 1. The transmission mechanism 45 includes a meshing rack 451 and a gear 452. The gear 452 is fixedly connected to the output shaft of the second motor 41. The rack 451 is located on the inner side of the loop frame 44. Driven by the second motor 41, the gear 452 and the rack 451 mesh with each other, causing the loop frame 44 to slide and lift, thus realizing the controllable positioning and clamping of the cable.

[0034] The locking module 3 uses a multi-bar linkage structure to lock / unlock the wedge block 54 interface, enabling quick engagement between the base 1 and the cable clamp 5. The branch line 6 uses a double gear 452 and a rack 451 for symmetrical transmission and lifting, gripping the main branch line 6, thus innovatively realizing an integrated installation method for the cable clamp 5 and the cable.

[0035] The operating principle of the present invention is described as follows:

[0036] When the device is in use, the first motor 31 drives the connecting rod structure 33, which in turn drives the locking block 32 to rotate and open the opening. Then, the wire clamp 5 is inserted into the interface, and the first motor 31 is driven to reverse, locking / unlocking the wire clamp 5 and realizing the quick engagement of the wire clamp 5. After connecting the branch line 6, the device is driven by a set of second motors 41 corresponding to the control top plate 42. The output shaft of the motor drives the top plate 42 to tighten the branch line 6 through the meshing of the gear 452 and rack 451, raising the base 1. The push plate 43 captures the main line 7, and the push plate 43 is then driven by a set of second motors 41 to grip the main line 7, thus innovatively realizing the integrated installation operation of the wire clamp 5 and the cable.

[0037] The above description is only a preferred embodiment of the present invention. It is impossible to exhaustively describe all embodiments here. However, the protection scope of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the protection scope of the present invention.
