Abstract
The utility model discloses a box-type base column nest structure. A box-type structure is arranged between the lower portion of a column nest and a baseplate and comprises a crossed rib set vertically welded on the baseplate, a subplate is welded on the upper portion of the crossed rib set, the column nest is arranged on the subplate, bracing ribs are vertically welded at positions where the upper surface of the subplate is intersected with the side faces of the column nest, and a transverse rib is welded between the outer end portions of the bracing rib as well as the subplate and the baseplate. By the box-type base column nest structure, load bearing capacity is improved greatly, and the problem that the bottom of a vertical column of a fully mechanized coal mining face is through can be solved.
Description
Technical field
The utility model relates to a kind of coal-mine hydraulic support parts, relates in particular to a kind of box base needling structure.
Background technology
Base needling is the critical component of coal-mine hydraulic support.
As shown in Figure 1 a, 1 b, base needling of the prior art is all on the backing plate being directly welded on base plate or base plate.When the enormous impact load of top board is relayed to column, then while being delivered to base needling, may have base needling top moment unstability, bottom stress sharp increase phenomenon, in the uneven situation of base plate, easily causes base needling to occur " internal injury " around, and easy-to-search not.In follow-up circulation, press in use procedure, " internal injury " problem under fatigue stress progressively exposes, and causes needling to wear the generation of end phenomenon.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can effectively prevents that needling from wearing the box base needling structure at the end.
The purpose of this utility model is achieved through the following technical solutions:
Box base needling structure of the present utility model, its preferably the specific embodiment be:
Between the bottom of needling and base plate, be provided with box structure, box structure comprises the cross-rib group being vertically welded on base plate, and the top of cross-rib group is welded with backing plate, and needling is located on backing plate.
The technical scheme being provided by above-mentioned the utility model can be found out, the box base needling structure that the utility model embodiment provides, owing to being provided with box structure between the bottom of needling and base plate, box structure comprises the cross-rib group being vertically welded on base plate, the top of cross-rib group is welded with backing plate, needling is located on backing plate, and supporting capacity increases greatly, can effectively prevent that needling from wearing the end.
Accompanying drawing explanation
Fig. 1 a is the side structure schematic diagram of base needling structure in prior art;
Fig. 1 b is the end face structure schematic diagram of base needling structure in prior art;
The structural representation of the box base needling structure that Fig. 2 provides for the utility model embodiment.

The specific embodiment
To be described in further detail the utility model embodiment below.
Box base needling structure of the present utility model, its preferably the specific embodiment be:
Between the bottom of needling and base plate, be provided with box structure, described box structure comprises the cross-rib group being vertically welded on described base plate, and the top of described cross-rib group is welded with backing plate, and described needling is located on described backing plate.
The crossing position in the upper surface of described backing plate and the side of described needling is vertically welded with support muscle.
Between the outer end of described support muscle outer end and described backing plate and described base plate, be welded with horizontal bar.
Box base needling structure of the present utility model, adopts " box " needling structure, can solve fully-mechanized mining working column and wear end problem.
Specific embodiment:
As shown in Figure 2, under base needling, increase elongated casing, make the suffered power part of needling be delivered to base plate by backing plate and cross-rib group, a part by sequence number support muscle, backing plate, cross-rib group, support muscle disperses to gap bridge, the horizontal bar of main muscle and needling front and back, reduce and shared the suffered concentrated load of base plate, can effectively avoid needling to wear the generation of end phenomenon.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
Claims (3)
1. a box base needling structure, it is characterized in that, between the bottom of needling and base plate, be provided with box structure, described box structure comprises the cross-rib group being vertically welded on described base plate, the top of described cross-rib group is welded with backing plate, and described needling is located on described backing plate.
2. box base needling structure according to claim 1, is characterized in that, the crossing position in the upper surface of described backing plate and the side of described needling is vertically welded with support muscle.
