Description

Technical Field

[0001] This utility model relates to an auxiliary tool for live-line work on high-voltage transmission lines, particularly a device suitable for quickly, safely, and accurately installing and removing bolt cotter pins on high-voltage transmission lines without interrupting power supply. Background Technology

[0002] With the development of drone technology, refined inspections of power transmission lines are becoming increasingly common, allowing for the identification and recording of numerous previously undetectable equipment defects. Data shows that missing cotter pins are the most frequent issue in power transmission line bolts and fittings, accounting for 80%-90% of all defects.

[0003] Since these defects are mostly concentrated on the conductor side or crossarm side, they are usually difficult to repair without meeting safety distance requirements, necessitating repairs via power outage or live-line work. Currently, most live-line working tools on the market suffer from low efficiency and difficulty in directional control, especially the inability to adjust the cotter pin and screw hole orientation in real time during operation, resulting in low installation efficiency and operational safety.

[0004] Therefore, there is an urgent need for a dedicated device that can automatically adjust direction and provide clear visual feedback to improve the safety and efficiency of live-line work on transmission lines. Utility Model Content

[0005] The purpose of this invention is to provide a device for quickly installing cotter pins on live high-voltage transmission lines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for rapid replacement of cotter pins on live high-voltage transmission lines includes an operating rod, an operating rod connecting device, and a screen receiving device. One end of the operating rod is connected to the operating rod connecting device, and a visual camera assembly is installed on the operating rod connecting device. The other end of the operating rod connecting device is provided with a clamping assembly, and an R-pin is connected to the top of the clamping assembly.

[0008] As a preferred embodiment of this utility model, the operating lever connecting device consists of an operating lever connector, a U-shaped extension rod, and a universal connector.

[0009] As a preferred embodiment of this utility model, the operating rod connecting device also has two structural forms: a right-angle extension rod and an L-shaped extension rod. The right-angle extension rod can rotate 90° in the planar direction, and the L-shaped extension rod can rotate 90° in the axial direction. The two structural forms can accommodate different hardware bolt hole positions on the straight crossarm.

[0010] As a preferred embodiment of this utility model, the visualization camera assembly includes a fixing clip, a universal joint is movably connected to the front of the fixing clip, a shielding shell is fixedly connected to one end of the front of the universal joint, an antenna is provided on one side of the shielding shell, a power display is provided on the front of the shielding shell, a switch button is provided on the front of the shielding shell and on the other side of the power display, a camera is provided on the other side of the shielding shell, and a power supply is provided inside the shielding shell.

[0011] As a preferred embodiment of this utility model, the clamping assembly includes a universal connector, set screws, a spring, and a mounting pin. Set screws are symmetrically arranged on both sides of the universal connector, and a spring is arranged at the top of the universal connector. A mounting pin is connected to one end of the top of the spring.

[0012] As a preferred embodiment of this utility model, the screen receiving device is used to observe the relative positions of the cotter pin and the screw hole on the pin head.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the coordinated use of accessories such as the operating lever, operating lever connecting device, and clamping assembly enables the rapid installation of R-pins in locations that are difficult to observe, such as the underside of the conductor fittings on tension towers. Simultaneously, the introduction of a visual camera assembly allows operators to observe and operate the device remotely via a screen, further reducing operational risks.

[0026] Example 1

[0027] like Figure 1-3 As shown, this utility model provides a technical solution: a device for rapid replacement of cotter pins on live high-voltage transmission lines, including an operating rod 1, an operating rod connecting device 2, and a screen receiving device 6. One end of the operating rod 1 is connected to the operating rod connecting device 2. A visual camera assembly 3 is installed on the operating rod connecting device 2. The visual camera assembly 3 includes a fixing clip 301. A universal joint 302 is movably connected to the front of the fixing clip 301. A shielding shell 303 is fixedly connected to one end of the front of the universal joint 302. An antenna 304 is provided on one side of the shielding shell 303. A power display 305 is provided on the front of the shielding shell 303. A switch button 306 is provided on the front of the shielding shell 303 and on the other side of the power display 305. A camera 307 is provided on the other side of the shielding shell 303. A power supply 308 is provided inside the shielding shell 303. A clamping assembly 4 is provided at the other end of the operating rod connecting device 2. An R-pin 5 is connected to the top of the clamping assembly 4. Through the above accessories, the device can mainly complete the repair of the difficult-to-observe position on the lower side of the conductor side fittings of the tension tower.

[0028] Connect the operating lever 1 to the operating lever connector 201 of the operating lever connecting device 2. Both have a toothed structure, and the engagement angle can be selected according to the on-site usage during installation. Figure 1 As shown in the top view, the universal connector 401 on the lower side of the adjustable clamping assembly 4 is then connected to the universal connector 203 of the operating rod connecting device 2. The universal connector 401 and the universal connector 203 are also toothed structures. During the installation process, the engagement angle can be selected according to the relative position of the R pin 5 and the bolt hole, and it can rotate within a 360° angle range.

[0029] The front-end installed visualization camera assembly 3 is mounted on the U-shaped extension rod 202. The fixing clamp 301 and the universal joint 302 cooperate with each other to achieve various angle adjustments, ensuring that the camera 307 can capture the image of the relative position of the R pin 5 and the bolt hole.

[0030] After all components of the device are connected, extend the operating lever 1 outwards to the working position. The power supply 308 of the visual camera component 3 will provide continuous power support, and the power display 305 can display the remaining power at any time so that the operator can charge or replace the battery in time. At the same time, the shielding shell 303 can effectively protect the camera 307 and internal circuits from external interference and damage, ensuring the clarity and stability of the image. The antenna 304 is responsible for wirelessly transmitting the image captured by the camera 307 to the image receiving screen 6. The image is transmitted to the image receiving screen 6 through the visual camera component 3 installed at the front end. The operator can observe the installation of the R pin 5. When the R pin 5 is aligned with the bolt hole, the R pin 5 can be installed. During this process, the spring 403 on the adjustable clamping component 4 can play a fine adjustment role to ensure that the R pin 5 can be pushed into the bolt hole in one go. After the R pin 5 is fully inserted into the bolt hole, move the entire device downwards, and the R pin 5 can be dislodged from the pin head 404. At this time, the R pin 5 installation process is completed.

[0037] The working process of this utility model is as follows: When using a live-line quick-installation cotter pin device for high-voltage transmission lines, the main function and effect of this device is to improve work efficiency, ensure work safety, and enhance work accuracy. Through the coordinated use of accessories such as the operating rod 1, the operating rod connecting device 2, and the clamping assembly 4, the device can quickly install the R-pin 5 to a difficult-to-observe location, such as the underside of the conductor fittings on the tension tower. Simultaneously, the introduction of the visual camera assembly 3 allows operators to observe and operate the device remotely via a screen 6, further reducing work risks. The visual camera assembly 3 can capture images of the relative position of the R-pin 5 and the bolt hole, and transmit the images via a screen 6. The screen 6 displays the information in real time to the operator, who can precisely adjust the position and angle of the R-pin 5 based on the information on the screen to ensure that the R-pin 5 can be accurately pushed into the screw hole. In addition, the spring 403 on the clamping component 4 can also play a fine-tuning role, further improving the accuracy of the operation. This utility model is applicable to live-line maintenance and repair of high-voltage transmission lines. Especially when bolts and fittings are missing cotter pins, this device can quickly and efficiently complete the replacement. It can be widely applied to live-line operation scenarios of power, distribution and transmission lines, effectively improving the intelligence level and safety of power grid maintenance.
