Abstract
The utility model discloses a base structure which is used for thin coal seam mining bracket. The base structure comprises a base body, a bridge and a passenger passage end. The bridge comprises a front bridge and a back bridge. The front bridge which is connected with the passenger passage end is a horizontally installed straight board. The back bridge which is installed on the reinforcing rod in the main body of base is an angle plate. The back bridge and reinforcing rod are mutually connected to a box shape. The base structure of the utility model causes the design of base structure more compact. The using performance of thin coal seam mining supporting device is increased.
Description
Technical field
The utility model relates to the coal mining equipment technical field, especially relates to a kind of base that is used for the thin seam mining support.
Background technology
In the support apparatus of coal mining, the base of hydraulic support is one of main pressure-containing member, the requirement of strength of base is quite high, and the performance requirement of base each side that is used for the thin seam mining support apparatus is higher, at first to reach the torsional strength requirement of hydraulic support under the resistance situation of operating at full capacity, secondly, the support Design that is used for girdle is all compact, if understructure is not transformed, when support drops to extreme lower position, each parts of support are easy to generate mutual interference, at last, in order not reduce the anterior intensity of bracket base, do not influence under the supporting project organization situation of three machines, cooperate pedestrian space and equipment management space before thin back timber structure is fully saved support, the walkway of base front end also needs redesign.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of understructure that is used for the thin seam mining support, makes the understructure design compact more, improves the functional performance of thin seam mining with support apparatus.
For achieving the above object, the utility model by the following technical solutions:
The understructure that is used for the thin seam mining support of the present utility model comprises base body, gap bridge and walkway end, passes a bridge before described gap bridge comprises and the back gap bridge, and passing a bridge before this links to each other with the walkway end, and preceding gap bridge is horizontally disposed straight plate; Passing a bridge and be arranged on the interior reinforcing rib of base body in the back, passes a bridge and be bent plate in the back, and the back gap bridge is coupled to each other into the casing shape with reinforcing rib; The thickness of walkway end is 130-140mm, and width is 460-470mm.
Further, the thickness of walkway end is 135mm, and width is 465mm.
The beneficial effects of the utility model are: the utility model has carried out compact design to understructure, under the requirement of satisfying base intensity, has solved each parts of support and has produced the problem of interfering mutually, has enlarged pedestrian walk space and equipment management space simultaneously.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following manual, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, according to lining coal seam conditions and exploitation requirement, when the design of support minimum altitude only is 0.7 meter, when understructure of the present utility model is implemented, comprise base body 1, gap bridge and walkway end 4, pass a bridge before described gap bridge comprises 2 and the back pass a bridge 3, passing a bridge before this 2 links to each other with walkway end 4, preceding gap bridge 2 is horizontally disposed straight plate.On the reinforcing ribs 5 that back gap bridge 3 is arranged in the base body 1, the reinforcing rib 5 of present embodiment refers to the main muscle that is arranged in the base body 1.Passing a bridge in the back 2 be bent plate, and back gap bridge 2 is coupled to each other into the casing shape with reinforcing rib 5.The thickness of walkway end is 135mm, and width is 465mm.
The understructure advantage of present embodiment is: not reducing the anterior intensity of bracket base, do not influence under the supporting project organization situation of three machines, cooperate pedestrian space and equipment management space before thin back timber structure is fully saved support.Solve support when extreme lower position, the problem that each parts of support are interfered mutually.The pattern of passing a bridge before and after bracket base adopts.The preceding gap bridge broken to pass a bridge before the fore-stock to founding the pattern of gap bridge, changes flat the gap bridge into; Passing a bridge and be arranged between the interior main muscle rear portion of bracket base in the back, connects main muscle in the base two with high-strength plank, courageously cancelled the body structure at existing base middle part.So both make base have torsional strength under the resistance situation of operating at full capacity, solved support again when extreme lower position, the problem that each parts of support are interfered mutually.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
Claims (2)
1. the understructure that is used for the thin seam mining support comprises base body, gap bridge and walkway end, it is characterized in that: pass a bridge before described gap bridge comprises and the back gap bridge, passing a bridge before this links to each other with the walkway end, and preceding gap bridge is horizontally disposed straight plate; Passing a bridge and be arranged on the interior reinforcing rib of base body in the back, passes a bridge and be bent plate in the back, and the back gap bridge is coupled to each other into the casing shape with reinforcing rib; The thickness of described walkway end is 130-140mm, and width is 460-470mm.
2. the understructure that is used for the thin seam mining support according to claim 1 is characterized in that: the thickness of walkway end is 135mm, and width is 465mm.
