Transformer substation hardware screw locking and dismounting device suitable for single mechanical arm

Abstract

The invention provides a transformer substation hardware screw locking and dismounting device suitable for a single mechanical arm. The device comprises a tool support and a mechanical arm connectingflange, an electric spanner, a spanner pushing air cylinder, a spanner moving frame, a nut clamp and a nut clamp control air cylinder are arranged on the tool support, wherein the nut clamp control air cylinder is fixed on a baffle plate on one side of the tool support, and the nut clamp is vertically installed above the nut clamp control air cylinder; the spanner moving frame is composed of a guide shaft bracket, a guide shaft and a sliding block, wherein the guide shaft bracket is fixed on a bottom frame, the guide shaft is arranged on the guide shaft bracket, and the sliding block is arranged on the guide shaft in a sleeving mode; and the electric spanner is horizontally fixed on the sliding block, the spanner pushing air cylinder is fixedly installed on the portion, far away from the nut clamp, of a tool support baffle, and the piston end of the spanner pushing air cylinder is connected with the sliding block. According to the transformer substation hardware screw locking and dismounting device, the screw locking and dismounting function of the single mechanical arm is realized, safety accidents caused by dropping of screws and nuts caused by shaking or other reasons are avoided, and electrified work is well carried out on the assembling and disassembling of the transformer substation hardware screws.

Description

technical field [0001] The invention provides a fitting screw dismounting tool, in particular to a substation fitting screw locking and dismounting device suitable for a single mechanical arm. Background technique [0002] With the continuous development of social digitization and informatization, the continuity and reliability of power supply is particularly important. As a method of maintenance and testing of high-voltage electrical equipment without power failure, high-voltage live working is an effective measure to avoid maintenance power outages and ensure normal power supply. Traditional high-voltage live-line work is done manually. Because the workers are in high-voltage and high-altitude environments, it has the disadvantages of heavy labor and high risk. With the development of robot technology and artificial intelligence technology, it has become a reality to use live working robots instead of manual cleaning and maintenance of substation equipment.

AI Technical Summary

Problems solved by technology

However, at present, the locking and unloading screws of the domestic live working manipulators all use double manipulators. In the process of locking and unloading the screws in this way, due to too much torque, the platform supporting the manipulator may be unstable or shake, and there is a big problem. Security risks

[0004] Existing published relevant patents, such as the Chinese patent document with the announcement number CN102240902B and the announcement date of May 1, 2013, disclose an automatic screw screwing machine, the screw positioning device includes a connected tool mold and a positioning groove, and the tool mold It includes a mold body and a clamping element hinged on the mold body, and the clamping element realizes the opening and closing action in the vertical direction; the Chinese patent screw positioning device with the announcement number CN102240902B and the announcement date being May 1, 2013, its zero There are many parts and complex structure, and its clamping elements also open and close vertically

In the two patents disclosed above, the clamping element opens and closes in the vertical direction, which takes up a lot of space. It is necessary to reserve a large insertion length for the screwdriver to prevent interference. In addition, the clamping element does not form a 360-degree angle to the screw. The clamping, the screw may be deflected and out of place, making the reliability of the automatic screwing machine not high

For the disassembly and assembly of substation hardware screws, the reliability requirements are higher, otherwise it will cause safety accidents
