Abstract

The invention provides a supporting and fastening device, which comprises a bracket, a first sloping block, a second sloping block, a movable support piece and a driving piece, wherein the bracket is provided with a hollow cavity; the side wall of the bracket is provided with an opening for communicating the cavity with the outside; the first sloping block and the second sloping block are arranged in the cavity, and are provided with oblique planes; the oblique planes of the first sloping block and the second sloping block are formed oppositely; the movable support piece is arranged in the cavity; the two ends of the movable support piece are contacted with the oblique surfaces of the first sloping block and the second sloping block respectively; the movable support piece is provided with a support part corresponding to the position of the opening; and the driving piece is used for driving the first sloping block and / or the second sloping block to reduce the distance between the first sloping block and the second sloping block, so that the movable support piece is used for driving the support part to move outwards along the oblique plane of each sloping block. The technical scheme of the invention has the advantages of easiness for clamping, reliable fixing, high efficiency, convenience for disassembling and assembling, and the like.

Description

technical field [0001] The invention relates to a support fastening device. Background technique [0002] The shearer frequency converter is an important electrical component in the coal shearer, which has the characteristics of large volume and high heat generation. Generally, one shearer needs to be installed with two shearer frequency converters. In order to ensure a good cooling effect and save space, the frequency converter of the shearer is installed vertically and equipped with a movable water channel cooling system. The fastening and installation of the frequency converter of the shearer installed vertically adopts the traditional bolt fastening method, but the support and fastening method using bolts has the problem of inconvenient clamping and disassembly, which affects the disassembly and assembly of the shearer frequency converter efficiency. Contents of the invention [0003] The present invention aims to provide a support and fastening device to solve the p...
