Description

Technical Field

[0001] The invention relates to the technical field of power maintenance auxiliary tools, in particular to a ground wire disassembly and assembly tool for overhead power transmission line maintenance. Background Art

[0002] Before carrying out power outage maintenance on overhead transmission lines, technical measures to ensure safety, such as electrical testing and grounding wires, must be strictly implemented on the maintenance lines to prevent workers from being attacked by sudden power supply, residual charge, and induced voltage from nearby high-voltage lines during maintenance. After the maintenance work is completed, the grounding wires must be removed in a timely manner.

[0003] For overhead transmission lines of 35kV to 220kV, a set of drop-type grounding wires is usually used. When hanging the grounding wire, the operator responsible for arranging the installation measures fixes the grounding clamp at the grounding end on the cross arm of the tower, and then stands on the cross arm of the tower and holds the insulating rope to control the wire clamp at the end of the grounding wire conductor. The wiring clamp is dropped and hung on the conductor to complete the installation of the grounding wire; when the grounding wire is removed, the wiring clamp is pulled out of the conductor with an insulating rope. It is difficult, time-consuming and inefficient to hang and remove the grounding wire using this drop-type method, especially when encountering a corner tower in the tension section, because the outer phase conductor is offset to the outside, it adds great difficulty to the installation and removal of the grounding wire.

[0004] According to a grounding wire disassembly and assembly system with patent number CN116914456A disclosed on the patent website, a clamping mechanism is used to clamp the insulating rod, which can prevent the insulating rod and the wire clamp from rotating when the rotating mechanism rotates the operating rod, thereby preventing the wire clamp from tilting when the wire clamp is clamped, increasing the stability of the wire clamp installation, and installing and disassembling the grounding wire through the insulating rod, increasing the distance between the operator and the wire, or as disclosed on the patent website, a patent number CN211208859U, an adjustable grounding wire block quick disassembly and assembly device, the bottom end of the insulating rod is provided with an insulating Insulation sleeve, a wire clamp base is arranged above the insulating rod, a grounding wire clamp outer shell is arranged above the wire clamp base, and an adjustable grounding wire clamp is arranged on the grounding wire disassembly and assembly device. When the grounding wire is being grounded, the grounding wire clamp can be aligned with the ground wire for installation. When it is on the outside of the grounding wire clamp, the grounding wire clamp can be pulled by a pull rope to rotate through the hinge and tilt the grounding wire clamp to the side to complete the docking of the ground wire. After loosening the pull rope, the grounding wire clamp can be automatically reset by a spring. When the ground wire is disassembled, the grounding wire clamp is tilted to complete the disassembly of the ground wire.

[0005] Among the existing operating tools and working methods, the method of hanging ground wires on tension towers by dropping is not only time-consuming, but also consumes a lot of energy of the operators. In case of emergency repairs in severe weather, the unnecessary working time will be greatly extended. Alternatively, the existing ground wire disassembly and assembly tools are used, which are complicated to operate, prone to failures, difficult to repair, and have large errors and high delays, which greatly increases the intensity and difficulty of emergency repair and maintenance tasks. Summary of the invention

[0006] The purpose of the present invention is to provide a grounding wire disassembly and assembly tool for overhead power transmission line maintenance. The driving block is controlled by a driving component designed on the control box. The driving block drives the wire hanging clamp to open and close to complete the wire hanging, which can greatly reduce the working time of the operators and improve the reliability and safety of the operation. At the same time, since the opening and closing of the wire hanging clamp can be remotely controlled, it has two functions of lateral fine-tuning and longitudinal adjustment, and the wire hanging clamp can be replaced according to actual needs, so that the operators can flexibly carry out the operation according to the actual situation on site, which effectively solves the problem of limited working angle of traditional methods.

For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. The present invention is described in detail in conjunction with the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional view showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional spatial dimensions of length, width and depth should be included. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0030] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0031] like Figure 1-Figure 3 As shown, the technical solution of the present invention proposes a ground wire disassembly and assembly tool for overhead power transmission line maintenance, comprising:

[0032] A wire hanging clamp 6 is used for hanging the conducting wire, and a grounding wire is fixed on the wire hanging clamp 6.

[0033] Disassembly and assembly tool assembly; the disassembly and assembly tool assembly includes a control box 1, the control box 1 has an inner cavity 9 for placing a wire hanging clamp 6, a driving block 7 driven by a driving component 4 is slidably connected in the inner cavity 9, a driving component 4 is installed on the control box 1, an output end of the driving component 4 is fixedly connected to the driving block 7, the driving component 4 is an electric push rod, and a power supply 5 connected to the driving component 4 is installed on the control box 1, and the driving component 4 can be powered by the power supply 5, wherein a remote control component can be installed on the driving component 4, and the ground staff can control the operation of the driving component 4 and the opening and closing of the wire hanging clamp 6 through the remote control, and its principle is similar to that of a remote control car, which is a prior art and will not be described in detail.

[0034] Example 1:

[0035] The upper end of the driving block 7 extends to the outside of the inner cavity 9, and a guiding slope 11 is provided on the upper end of the driving block 7. The guiding slope 11 is arranged opposite to the driving component 4. When the wire hanging clip 6 is placed in the inner cavity 9, the wire hanging clip 6 is abutted against the guiding slope 11, and the guiding slope 11 guides the wire hanging clip 6, which makes it easier to place the wire hanging clip 6 in the inner cavity 9; wherein, a side groove 10 is provided on the inner wall of the inner cavity 9, and the side groove 10 has the same width as the inner wall of the inner cavity 9.

[0036] Among them, the side groove 10 is arranged in cooperation with the wire hanging clip 6. When the wire hanging clip 6 is placed in the inner cavity 9, the driving block 7 is driven to move by the driving component 4 and abuts against the wire hanging clip 6, which can drive the wire hanging clip 6 to move and move one side of it to the side groove 10, thereby increasing the space of the inner cavity 9.

[0037] Specifically, start the power supply to supply power to the driving component 4, use remote operation to control the driving component 4, the driving block 7 moves to push the hanging wire clamp 6, and can realize the control of the hanging wire clamp 6 to open and close. When the driving block 7 is away from the hanging wire clamp 6, the hanging wire clamp 6 is closed and clamped on the wire. When the driving block 7 squeezes the hanging wire clamp 6, the hanging wire clamp 6 opens and the wire hangs down. A detachable insulating rod 2 is installed at the bottom of the control box 1, and a threaded sleeve 8 is fixed at the bottom of the control box 1. A threaded column 12 is fixed at the upper end of the insulating rod 2. The threaded column 12 extends into the threaded sleeve 8 and is threadedly engaged, which is convenient for disassembly and assembly between the insulating rod 2 and the control box 1. The connection method is simple and stable. An anti-slip sleeve 3 is fixed at the bottom of the insulating rod 2, and a protrusion of the device that is convenient for rotation is provided on the anti-slip sleeve 3, which is convenient for the staff to hold and use.

[0038] The staff puts the wire clip 6 in the inner cavity 9 and moves the insulating rod 2 upward, so that the wire clip 6 is close to the wire, and the driving component 4 is started to work. The driving component 4 drives the driving block 7 to move, and the driving block 7 moves to abut against the wire clip 6, which can drive the wire clip 6 to move and move one side of it to the side groove 10. Finally, under pressure, the wire clip 6 opens, and the wire clip 6 is added to the wire. The output end of the driving component 4 drives the driving block 7 to reset, and the wire clip 6 can be clamped on the wire using its own torsion spring;

[0039] Example 2:

[0040] After the maintenance work is completed, the staff needs to remove the connected grounding wire in time. When removing it, use an insulating rope to pull the wiring clamp out of the wire. In actual work, it is often encountered that it cannot be removed in time. This example provides a method for removing the grounding wire. Turn on the power 5 of a grounding wire disassembly and assembly tool for overhead power transmission line maintenance, control the drive block 7 to move away from the wire clamp 6, take out the wire clamp 6, put the wire clamp to be taken into the inner cavity 9, control the drive block 7 to squeeze the wire clamp 6, and use the drive block 7 to drive the wire clamp 6 to open, and then it can be removed.
