Problems solved by technology

When the top plate is broken and needs to be attached and moved, the frictional resistance between the top plate and the top beam will generate a moment that makes the bracket fall backwards, making it difficult to move the frame

Embodiment Construction

[0019] With reference to Fig. 1 and Fig. 2, the first embodiment of a frame moving device of the present invention includes a top beam 1; one end is connected to a telescopic front extension beam of the frame, and the other end is connected to a front extension beam of an adjacent bracket. The connecting piece 8 connected by the beam; the front extension beam oil cylinder 7 hinged with the top beam through the pin 10, the left front extension beam 5 and the right front extension beam 6 which are mounted in the same top beam and hinged with the front extension beam oil cylinder through the pin 9 .

[0020] The action sequence when a frame moving device of the present invention is matched with the integral top beam type hydraulic support in the underground working face is described below in conjunction with FIG. Beam 1, top beam 2, top beam 3, top beam 4 and top beams of other supports are densely arranged in a horizontal row. After the coal falls, the adjacent two front extens...

Abstract

The present invention discloses a transferring support device used in hydraulic support at coal mine underground working surface top board support, includes top beam , telescopic front extending beam 5 and 6, oil cylinder 7, hinge 9 and 10, connecting mechanism 8. the characteristic of the invention is: the telescopic front extending beam impelled by oil cylinder 7 has at least a connecting component 8 for moving support connected with the front extend beam which is adjacent to hydraulic support. When working surface is used, a hydraulic support equipped with a transferring support device is in a horizontal row. After coal dropping, the adjacent front extending beam extends out synchronously, and front extending beam of every support will be the extending state. the adjacent front extending beam and connecting component 8 are fixing point when support is moved, the front extending beam driven by oil cylinder 7 is shrunk to moving support, and the support device can be omitted. The product can overcome friction resistance between top board and top beam, and can prevent backwards tipping support, when is matched with the fully-mechanized mining bracket, etc. Furthermore, the productcan also prevent tipping support toward other way.

Description

technical field [0001] The invention relates to a frame moving device for a hydraulic support used for underground mining face support. Background technique [0002] The hydraulic supports are divided into two categories: sliding top beam hydraulic supports and fully mechanized mining supports. The present invention is a frame moving device for these two types of hydraulic supports. Its background technology also has two major categories, and the first category is the technology described in the "General Technical Conditions for Sliding Roof Beam Hydraulic Supports" of China's coal industry. Existing technology in this field has suspension top beam hydraulic support (Chinese patent application number 88104291.9); Trident hydraulic support (Chinese patent application number 96209441.2); Side-by-side sliding top beam hydraulic support (Chinese patent application number 91200747.8) Wait. Above-mentioned these supports all are made up of parts such as hydraulic strut, front ex...
