Abstract
The utility model discloses an edge protecting beam structure of a hydraulic support and the hydraulic support. The edge protecting beam structure comprises a top plate, two side main ribs are longitudinally arranged on the two sides of the web face of the top plate, a hinge lug is formed at the rear end of each of the two side main ribs and hinged to a top beam, one or more middle main ribs are longitudinally arranged in the middle of the web face of the top plate, and cover plates and transverse ribs are arranged between the adjacent side main ribs, between the side main ribs and the middle main ribs and between the adjacent middle main ribs. The design concept of an edge protecting plate in the prior art is changed, the structural design of a beam is adopted, and torsion resistance and anti-bending strength of the edge protecting beam are improved.
Description
Technical field
The utility model relates to a kind of coal-mine hydraulic support, relates in particular to a kind of wall supporting girder construction and hydraulic support of hydraulic support.
Background technology
Side protecting mechanism is the conventional setting of the one of hydraulic support, is positioned at set cap front portion, and under the effect of wall supporting jack, face guard support rib, prevents wall caving, guarantees support below personnel's life security.Face guard is the core component of side protecting mechanism, and in actual applications, when rib is softer, when wall caving is serious, face guard is often crushed out of shape, and even damages, and is difficult to repair.
Utility model content
The purpose of this utility model is to provide wall supporting girder construction and the hydraulic support of the hydraulic support that a kind of reliability is high.
The purpose of this utility model is achieved through the following technical solutions:
The wall supporting girder construction of hydraulic support of the present utility model, comprise top board, the both sides of the outside of belly of described top board are longitudinally provided with respectively two main muscle of sidepiece, the rear end of two main muscle of sidepiece forms hinged ear, the middle part of the outside of belly of described top board is longitudinally provided with the main muscle in one or more middle parts, between the main muscle of adjacent sidepiece, between the main muscle of the main muscle of sidepiece and middle part, be provided with cover plate and horizontal bar between the adjacent main muscle in middle part.
Hydraulic support of the present utility model, this hydraulic support is provided with the wall supporting girder construction of above-mentioned hydraulic support, and described hydraulic support comprises back timber, and hinged ear and the described back timber of described two the main muscle of sidepiece rear ends are hinged.
The technical scheme being provided by above-mentioned the utility model can be found out, wall supporting girder construction and the hydraulic support of the hydraulic support that the utility model embodiment provides, owing to having changed the mentality of designing of wall supporting " plate " in prior art, adopt the structure design of " beam ", and adopt two hinged ears of main muscle and back timber hinged, and as far as possible many places increase cover plate, seal into casing, improved antitorque, the flexural strength of wall supporting beam.
Accompanying drawing explanation
The outside of belly structural representation of the wall supporting girder construction of the hydraulic support that Fig. 1 a provides for the utility model embodiment;
Fig. 1 b is that the A-A of Fig. 1 a is to structural representation;
Fig. 1 c is that the B-B of Fig. 1 a is to structural representation;
