Abstract

An automatic chassis device for a 35KV high-voltage switch cabinet cart comprises an electromotor (1), an elastic clutch (4), a ball screw (6), and a pull rod (8). The electromotor (1) is connected to an electromotor support (2). The electromotor (1) is connected to the ball screw (6) through the elastic clutch (4). One end of the ball screw (6) is connected to a large end socket (3), and the other end thereof passes through a movable plate (7) and is connected to a small end socket (9) and an end socket (12). A support plate (5) is disposed at each of two ends of the large end socket (3). The pull rod (8) is disposed at each of two ends of the movable plate (7). An encoder (10) and a gear (11) are disposed between the small end socket (9) and the end socket (12). An end of the ball screw (6) is designed into a hexagonal prism. The automatic chassis device can not only implement a dynamoelectric operation for moving the cart in or out, but also reliably implement a manual operation, and the two operation modes can be conveniently switched, thereby achieving reliable interlocking.

Description

Automatic chassis device for 35KV rolling switch cabinet car

Technical field:

The utility model relates to an automatic chassis device which is widely used for industrial production in a switch cabinet car with simple structure and convenient operation.

Background technique:

In the current 35KV high-voltage switchgear, most of the products can only be manually operated in and out. Although some products can be electrically operated in and out, the original manual operation function cannot be used normally. In order to solve this problem, the patent relates to an automatic chassis device, which can realize the electric operation of the hand-car in and out of the 35KV high-voltage removal switch device, and can be reliably operated manually, and the two operation modes can be conveniently switched and reliable. Interlocking. It provides the necessary hardware foundation for automatic control and remote control of 35KV high voltage switchgear.

Utility model content

The technical problem to be solved by the utility model is to realize the manual operation in the high-voltage removal type switch device, and solve the problems of safety, convenient operation and the like.

The main technical features of the utility model are as follows: Mainly, the motor, the elastic coupling, the ball screw, the drawbar, the motor is connected with the motor support, the motor and the ball screw are connected by a flexible coupling, one end of the ball screw and the large The head is connected, the other end is connected to the small head through the movable plate, and the head is connected. A support plate is arranged at each end of the large head, and a pull rod is arranged at each end of the movable plate, and the small head and the head are arranged. Between, an encoder and gear are set, and the end of the ball screw is designed as a hexagonal column.

The utility model has the beneficial effects that the system is stable and accurate, and the perfect protection function includes multiple protections such as overcurrent, overvoltage, undervoltage and stalling.
