Assembly device for rotatable and horizontally fixable assemblies in suitable height of electromagnetic starter base plate

Abstract

The invention discloses an assembly device for rotatable and horizontally fixable assemblies in suitable height of an electromagnetic starter base plate, which is characterized in that the device is composed of a connecting block, a rotary frame, a support frame, a bottom support platform and support legs; that one end of the connecting block is connected with a long circular hole in the rotary frame through a bolt, and the other end thereof is connected with the base plate also through a bolt.; that an assembly base plate is arranged in the rotary frame and is fixed by the connecting block; that projecting shafts are arranged in the middle of two edges of the rotary frame, wherein the projecting shafts are erected on U-shaped grooves of the support frame; that the support frame is provided with bolts, and bottom of the support frame is equipped with an inverted T-shaped short card, wherein the short card is caught in a guide-track groove of the bottom support platform; and that supporting legs are arranged under the bottom support platform. The device has the advantages that the base plate can be supported to a suitable height, which is convenient for operation; that the base plate can be overturned and horizontally fixed, which is convenient for assembly of assemblies on two sides; and that size of the rotary frame and the support frame is adjustable, which is suitable for matched connection among base plates of different sizes.

Description

technical field [0001] The invention relates to the installation of components on the bottom plate of an electromagnetic starter, in particular to a component assembly device which can rotate and fix the bottom plate of the electromagnetic starter at a suitable height. Background technique [0002] Coal is an important basic energy source in my country. The basic characteristics of my country's energy resources are rich in coal, poor in oil, and low in gas. The proven resource reserves are converted into standard coal, and coal accounts for more than 85%. The "Twelfth Five-Year Plan for Coal Mine Safety Production" proposes to focus on promoting the mechanization process of small coal mines, comprehensively improve the productivity level of small coal mines, and cultivate safety equipment manufacturing enterprises with strong technical capabilities. Explosion-proof vacuum reversible electromagnetic starters for mining are widely used in coal mine production to protect the s...

Problems solved by technology

The electrical part is the most important part of the electromagnetic starter. Components are installed on both sides of the electrical base plate. Generally, one side is installed first, then turned over after installation, and then placed on the installation table to install the other side. Sometimes the components are installed on the electrical base plate. It is relatively full, so you can't directly place the electrical bottom plate on the installation table, you can only place the side of the installed components on the bottom, and then install the upper components, which is easy to crush the lower components

At the same time, because the electrical components are generally heavy, if the installer manually flips them, the labor intensity is high, and accidents are prone to occur.
