Abstract
The invention discloses a forging needling and a hydraulic support, wherein the forging needling comprises a needling body. Two sides of the needling body are respectively provided with a large lug plate, the needling body and the large lug plates are integrally forged, a pin shaft hole is arranged in each large lug plate, two sides of each pin shaft hole are respectively provided with a small lug plate, the small lug plates are welded on the outer side surface of the large lug plate and the upper surface of the needling body, and pin blocking holes are arranged on the small lug plates. The forging needling is welded on a top beam of the hydraulic support and then the top beam is connected with a column cap of a vertical column, therefore, the use is convenient, the structure is simple, the forging difficulty is small, and the manufacturability is better.
Description
Technical field
The present invention relates to a kind of hydraulic support parts, relate in particular to a kind of forging needling and hydraulic support.
Background technology
Hydraulic support is when underground work, and mainly the face roof that back timber is born by needling is pressed and is delivered on the column, thereby requires very high to the supporting capacity of needling.Compare with common casting needling, forge needling and can avoid the easy defectives such as crackle, pore, shrinkage cavity, shrinkage porosite, misrun, scab and mould shift distortion that occur in the foundry goods, compressive strength is better, and toughness is better, anti-torsion ability is stronger, and is not easy to crack with the weld seam of back timber welding.
Forging needling complex structure of the prior art, the forging difficulty is big, manufacturability is relatively poor, and uses inconvenient with being connected of column.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, forge that difficulty is little, manufacturability is better, and with being connected of column forging needling and hydraulic support easy to use.
The objective of the invention is to be achieved through the following technical solutions:
Forging needling of the present invention, comprise the needling body, the both sides of described needling body are respectively equipped with big ear plate, described needling body and described big ear plate solid forging form, described big ear plate is provided with pin shaft hole, the both sides of described pin shaft hole are respectively equipped with small ear plate, and described small ear plate is welded on the upper surface of the lateral surface of described big ear plate and described needling body, and described small ear plate is provided with the backing pin hole.
Hydraulic support of the present invention, comprise back timber, column, be welded with above-mentioned forging needling on the described back timber, the cap of described column upper end is against on the described needling, insert bearing pin in the pin shaft hole on the described big ear plate, this bearing pin is inserted in the blind hole on the described cap, is inserted with backing pin in the backing pin hole on the described small ear plate, and described backing pin retaining is in the rear end of described bearing pin.
As seen from the above technical solution provided by the invention, forging needling provided by the invention and hydraulic support, because the both sides of needling body are respectively equipped with big ear plate, needling body and big ear plate solid forging form, big ear plate is provided with pin shaft hole, the both sides of pin shaft hole are respectively equipped with small ear plate, and small ear plate is welded on the upper surface of the lateral surface of big ear plate and needling body, and small ear plate is provided with the backing pin hole.After being welded with above-mentioned forging needling on the back timber of hydraulic support, be connected with the cap of column, easy to use, simple in structure, forge that difficulty is little, manufacturability is better.
Description of drawings
The structural representation of the forging needling that Fig. 1 provides for the embodiment of the invention;
Fig. 2 is the structural representation of needling body and big ear plate in the embodiment of the invention;
Fig. 3 is the structural representation of small ear plate in the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
Forging needling of the present invention, its preferable specific embodiment be as shown in Figure 1 and Figure 2:
As shown in Figure 3, described small ear plate 3 is provided with backing pin hole 5.
Hydraulic support of the present invention, its preferable specific embodiment is:
Comprise back timber, column, be welded with above-mentioned forging needling on the described back timber, the cap of described column upper end is against on the described needling, insert bearing pin in the pin shaft hole on the described big ear plate, this bearing pin is inserted in the blind hole on the described cap, be inserted with backing pin in the backing pin hole on the described small ear plate, described backing pin retaining is in the rear end of described bearing pin.
Forging needling of the present invention can be used as a black box and is soldered directly on the back timber of hydraulic support, is connected with the cap of column, and can the needling size be suitably revised according to the physical dimension of the back timber and the cap of different support, and is promptly applicable.
Specific embodiment:
As shown in Figure 1, the present invention forges on the needling at one to have welded 4 small ear plates, does not need to forge small ear plate during owing to forging, thereby greatly reduces the forging difficulty, and manufacturability is better;
This kind forging needling and column type of attachment are simple, highly versatile.It is hinged that needling and the cap of column are connected bearing pin by two, the backing pin axle is inserted in employing on small ear plate form limits the degree of freedom that connects the bearing pin move left and right, dismounting only need be pulled down the backing pin axle earlier during column, will connect bearing pin then and transfer to from the blind hole of cap and get final product;
Simple in structure, in light weight, not only be easy to forge, more saved cost.
The present invention is applicable in the dissimilar hydraulic supports, and is simple with the column type of attachment, and mounting or dismounting are convenient, highly versatile; Adopt and forge the original casting needling of needling replacement, improved the security reliability of support greatly, satisfy the requirement of high end support coupled columns nest; Solid forging is carried out in main part of the force in the needling assembly, stressed little small ear plate is welded on the forging after the processing separately, so promptly satisfy instructions for use, greatly reduce the forging difficulty again, good manufacturability.
The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
