Embodiment Construction

[0057] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present application, and are not construed as limiting the present application.

[0058] First, introduce and explain the nouns involved in this application:

[0059] The roof refers to the exposed ore layer or rock layer at the top of the working face.

[0060] The bottom plate refers to the ground of the working surface.

[0061] combine Figure 1 to Figure 5 As shown, the embodiment of the present application provides a support structure, including: a main roof beam support 100 and a secondary roof beam support 200 for alternately supporting the roof.

[0062] Below the main roof beam support 100 is provided a liftable ...

Abstract

The invention provides a support structure, supporting equipment and coal mining complete equipment. The support structure comprises a main top beam support and an auxiliary top beam support which are used for alternately supporting a top plate; a liftable main supporting assembly is arranged below the main top beam support, and one end of the main supporting assembly is detachably connected to the main top beam support; a liftable auxiliary supporting assembly is arranged below the auxiliary top beam support, and one end of the auxiliary supporting assembly is detachably connected to the auxiliary top beam support; and a first driving component is arranged between the main top beam support and the auxiliary top beam support, one end of the first driving component is detachably connected to the main top beam support, the other end of the first driving component is detachably connected to the auxiliary top beam support, and one end and the other end of the first driving component can slide relatively. The main top beam support and the auxiliary top beam support are mutually shielded and move forwards so that a broken top plate can be alternately supported when the supports move forwards; and all parts of the support structure can be disassembled and transported, and the structure assembled on the working face can conveniently enter a small-diameter wellhead or a small-section roadway, so that the economic benefit is high.

Description

technical field [0001] The application relates to the technical field of coal mining, in particular, the application relates to a support structure, support equipment and a complete set of coal mining equipment. Background technique [0002] When carrying out coal mining, the working face needs to use support equipment. [0003] At present, there are two main types of support equipment for coal mining working faces in coal mines, fully mechanized mining supports and sliding hydraulic supports. Because large supports cannot enter smaller wellheads, some coal mines have no supports available for top coal caving working faces. In mines at the end, mines with small resource areas, broken roofs, false roofs, and corner coal mining areas of large mines, the economic benefit of using large supports is low. [0004] Therefore, the market needs a kind of fully-mechanized mining support that can conveniently enter smaller wellhead badly. Contents of the invention [0005] Aiming a...
