Description

Technical Field

[0001] The utility model relates to a grounding switch installation tool, belonging to the technical field of grounding switch assembly. Background Art

[0002] The high-voltage grounding switch is an important component of the high-voltage switchgear. It is a mechanical switching device used to ground the circuit. Under abnormal conditions, such as short circuit, it can carry the specified abnormal current within a specified time; but under normal circuit conditions, it is not required to carry current.

[0003] The high-voltage grounding switch includes a housing, a driving rod and a driving mechanism. A moving contact and a stationary contact are installed in the housing. One end of the driving rod is connected to the moving contact, and the other end extends out of the housing and is connected to the driving mechanism. The driving mechanism drives the driving rod to move, and the driving rod drives the moving contact to move, thereby realizing the opening and closing of the moving and stationary contacts. During the assembly of the grounding switch, if the driving rod is inserted too much into the housing, the moving contact will collide excessively with the stationary contact when the high-voltage grounding switch is closed, thereby causing damage to the moving contact and the stationary contact. If the driving rod is inserted too little into the housing, when the high-voltage grounding switch is closed, the moving contact and the stationary contact will have poor contact. Therefore, the axial installation position of the driving rod of the high-voltage grounding switch on the housing of the grounding switch must be accurate.

[0004] In the prior art, the grounding switch is assembled by using a crane to lift the driving rod to the housing installation position, and then using manpower to install the driving rod on the housing. In order to achieve accurate installation of the driving rod on the grounding switch housing, the driving rod needs to be roughly positioned on the grounding switch housing first, and then the driving rod is struck with a hammer to fine-tune the installation position. However, when the driving rod is struck with a hammer, factors such as hand strength and the matching accuracy between the driving rod and the housing may affect the driving rod and cause it to fall too far. It is also necessary to pull out the driving rod in the opposite direction and then readjust the installation position of the driving rod. This random and rough pulse installation method is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0005] The utility model aims to provide a grounding switch installation tool to solve the technical problem of time-consuming and labor-intensive manual installation of a driving rod in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the grounding switch installation tool comprises a base and a top seat, the base and the top seat are connected by a vertical seat, the base is provided with a through hole for connecting with the cylinder flange of the grounding switch, the top seat is provided with a transmission member for connecting with the driving rod of the grounding switch, a continuous driving device for driving the transmission member to move, and a guide structure for guiding the transmission member up and down.

[0007] The technical effect of the above technical scheme is: the base and the top seat are connected through the vertical seat to form a frame structure, the through hole on the base is used to connect with the flange of the grounding switch, the top seat forms the installation base of the transmission member and the continuous driving device, and the cooperation of the continuous driving device and the guide structure on the top seat can ensure the up and down guiding movement of the transmission member, and the continuous driving device can linearly drive the driving rod up and down. After the transmission member is connected to the driving rod, the transmission member can drive the driving rod on the grounding switch to move linearly up and down. Compared with the random and rough pulse installation method of hitting the driving rod with a hammer in the prior art, the tooling can quickly and conveniently install the driving rod accurately on the grounding switch.

The continuous driving device is a gear installed in the gear mounting cavity with its axis horizontal. The transmission member is a rack guided and installed in the rack mounting hole.
