Abstract

The invention provides a mine explosion-proof low-voltage vacuum electromagnetic starter, and belongs to the technical field of electromagnetic starters. The mine explosion-proof low-voltage vacuum electromagnetic starter comprises an electromagnetic starter body, a vertical plate and a support, wherein the support comprises two base frames, an L-shaped fixed plate, a support block and a rolling wheel; each base frame comprises a first cross plate, inclined plates connected to the two ends of the first cross plate and arranged slantwise away from the first cross plate, and a second cross plateconnected with the inclined plates; one side of the L-shaped fixed plate is fixed to the first cross plates, and the other side of the L-shaped fixed plate is fixedly connected with the vertical plate; a first bolt hole is formed in each inclined plate; through grooves passing through the base frames are formed in the support block, and two vertically-distributed second bolt holes vertical to thethrough grooves and matched with the first bolt holes are formed in the support block; and the vertical height of each first bolt hole away from the corresponding first cross plate is greater than the vertical height of the lower second bolt hole away from the bottom of the rolling wheel, and less than the vertical height of the upper second bolt hole away from the bottom of the rolling wheel. The mine explosion-proof low-voltage vacuum electromagnetic starter is simple in structure, convenient to move, and good in anti-shock and anti-dumping effects.

Description

technical field

[0001] The invention belongs to the technical field of electromagnetic starters, in particular to a mine explosion-proof low-voltage vacuum electromagnetic starter. Background technique

[0002] The base of the traditional mine flameproof low-voltage vacuum electromagnetic starter is very simple. It consists of a simple flat plate, and the electromagnetic starter is connected to the flat plate with bolts. It is a site that is directly placed without a base bracket. At present, the operating environment of the mine vacuum electromagnetic starter is relatively harsh. In addition to the need for explosion-proof, of course, there are also the needs of shock resistance and convenient movement. However, the current mine vacuum electromagnetic starter lacks a reasonable base bracket, which is easy to cause vibration. It is troublesome to dump and move, which not only affects the safe use of the mine vacuum electromagnetic starter, but also consumes more manpower. ...
