Embodiment 1

[0036] Please refer to Figure 1-3 , when it is used for the pin removal work where the opening direction of the insulator pin is perpendicular to the line direction,

[0037] This embodiment provides a remote-operated multifunctional pin-removing pliers, including an operating rod 1, a pin-removing pliers 4, and a clamping mechanism 2 that drives the opening and closing of the pin-removing pliers 4, and the clamping mechanism 2 includes mirror images. Two hinge bases 21 and two pin-removing pliers connectors 22 arranged in mirror images, and hinged between two adjacent hinge bases 21 and pin-removing pliers connectors 22 through a living hinge 23; The driving mechanism 3 that two hinge seats 21 move toward or away from each other; the driving mechanism 3 includes a transmission screw 31 fixedly connected with the operating rod 1, and the transmission screw 31 is a positive and negative screw, and the two hinges Seat 21 is threadedly connected with the two ends of positive an...

Embodiment 2

[0045] Please refer to Figure 3-6 , when it is used for the pin removal work where the opening direction of the insulator pin is the horizontal line direction, the difference between this embodiment and Embodiment 1 is that the fixing cavity is used to fix the fixing plate 411, and the working principle is the same as that of Embodiment 1. Works on the same principle.

[0046] In order to make the information collection end of the vision sensor 6 better towards the opening of the pin removal pliers 4, in this embodiment, the vision sensor 6 is arranged on the hinge seat 21, so that the height of the vision sensor 6 is the same as that of the pin removal pliers 4. The height is consistent, so that the information collection end of the visual sensor 6 is facing the opening position of the pin-removing pliers 4, and the working conditions of the pin-removing pliers 4 can be collected more comprehensively.

Embodiment 3

[0048] Please refer to Figure 7 and image 3 , when it is used for the pin removal work where the opening direction of the insulator pin is perpendicular to the line direction,

[0049] This embodiment provides a remote-operated multifunctional pin-removing pliers, including an operating rod 1, a pin-removing pliers 4, and a clamping mechanism 2 that drives the opening and closing of the pin-removing pliers 4, and the clamping mechanism 2 includes mirror images. Two hinge bases 21 and two pin-removing pliers connectors 22 arranged in mirror images, and hinged between two adjacent hinge bases 21 and pin-removing pliers connectors 22 through a living hinge 23; The drive mechanism 3 for the two hinge seats 21 to move toward or away from each other; the drive mechanism 3 includes: the shaft working section of the operating rod 1 is provided with threads, and the threaded working section of the operating rod 1 is threaded with a first hinge The front end of the operating rod 1 i...

Abstract

The invention relates to the field of electric power maintenance tools, and discloses a remote-operated multifunctional pin removal pliers, including an operating rod, a pin removal pliers, and a clamping mechanism that drives the opening and closing of the pin removal pliers. The clamping mechanism includes two The hinge base and the two pin-removing pliers connectors arranged in mirror image, and the two adjacent hinge bases and the pin-removing pliers connectors are hinged by a living hinge, and also include a drive that drives the two hinge bases of the clamping mechanism to move toward or away from each other Mechanism; the connecting part of the pin removing pliers includes a horizontal connecting arm and a vertical connecting arm vertically connected to the horizontal connecting arm, and the two ends of the horizontal connecting arm are hinged with the living hinge; The fixed plate, the end of the clamp rod or the fixed plate is fixedly connected with the vertical connecting arm. The invention can be operated remotely, reducing the risk of workers falling from high altitude; at the same time, it is suitable for pulling cotter pins in vertical lines and parallel lines, with flexible and convenient operation, time-saving, labor-saving, high efficiency and high accuracy.

Description

technical field [0001] The invention relates to the field of electric power maintenance tools, in particular to a remote-operated multifunctional pin-removing pliers. Background technique [0002] An insulator is a device that is installed between conductors of different potentials or between conductors and grounding components that can withstand voltage and mechanical stress. In the process of connecting insulators to conductors or grounding components, M-type and R-type cotter pins are commonly used , One end or all of the M-type and R-type cotter pins are embedded in the insulator. With the rapid development of ultra-high voltage and ultra-high voltage lines, the maintenance tasks of transmission lines are becoming more and more numerous, and the work requirements are constantly improving. Usually, when the insulator is replaced during maintenance, professional tools must be used to extract the M-type and R-type cotter pins before the replacement operation can be carried...
