Abstract
The utility model discloses a forging needling and a hydraulic support. The forging needling comprises a needling body. A big lug is respectively arranged on two sides of the needling body, a pin shaft hole is arranged on each big lug, a small lug is respectively arranged on two sides of each pin shaft hole, the small lugs are welded to an outer lateral side of each big lug and the upper surface of the needling body, and a pin retaining hole is arranged on each small lug. The forging needling is welded to a top beam of the hydraulic support, and then the hydraulic support is connected with column caps, thereby being convenient to use, simple in structure, small in forging difficulty and good in manufacturability.
Description
Technical field
The utility model relates to a kind of hydraulic support parts, relates 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.
The utility model content
The purpose of this utility model 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 purpose of this utility model is achieved through the following technical solutions:
Forging needling of the present utility model, comprise the needling body, the both sides of described needling body are respectively equipped with big ear plate, 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, 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 utility model, 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.
The technical scheme that is provided by above-mentioned the utility model as can be seen, forging needling and hydraulic support that the utility model provides, because the both sides of needling body are respectively equipped with big ear plate, big ear plate is provided with pin shaft hole, the both sides of pin shaft hole are respectively equipped with small ear plate, 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 utility model embodiment;
Fig. 2 is the structural representation of needling body and big ear plate among the utility model embodiment;
Fig. 3 is the structural representation of small ear plate among the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Forging needling of the present utility model, 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 utility model, 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 utility model can be used as a black box and is soldered directly on the back timber of hydraulic support, be connected with the cap of column, and can the needling size suitably be revised according to the physical dimension of the back timber and the cap of different support, promptly applicable.
Specific embodiment:
As shown in Figure 1, the utility model is to forge 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 utility model 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; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; 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 all should be encompassed within the 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.
