Abstract
The invention discloses a cracking-proof peristome of a top beam of a hydraulic support. The peristome comprises two overlapped plates in the same shape; and the two plates are welded integrally. The total thickness of the peristome is not limited by the specifications of the plates, so the cracking of the peristome can be avoided effectively.
Description
Technical field
The present invention relates to a kind of hydraulic support, relate in particular to a kind of hydraulic support back timber lip.
Background technology
Hydraulic support is under the bad working environments of down-hole, and the lip of back timber (front console of back timber) is cracking easily, prevents the cracking of lip in the prior art by the thicker sheet material of selection.
There is following shortcoming at least in above-mentioned prior art:
On the one hand, lip is subjected to the restriction of sheet material specification and design thickness, can not select arbitrarily; On the other hand, concentrate and the crack effect, still keep away the cracking of unavoidable lip by single increase thickness because lip is easy to generate stress.
Summary of the invention
The purpose of this invention is to provide a kind of hydraulic support back timber lip that can effectively avoid the anti-cracking of lip cracking.
The objective of the invention is to be achieved through the following technical solutions:
Anti-cracking hydraulic support back timber lip of the present invention comprises that the identical plate of two-layer shape is superimposed, and is welded into integral body between the two-ply.
As seen from the above technical solution provided by the invention, the anti-cracking hydraulic support back timber lip that the embodiment of the invention provides is owing to comprise that the identical plate of two-layer shape is superimposed, and is welded into integral body between the two-ply.Strengthened the thickness of labial lamina on the one hand, the gross thickness that makes lip is not in the restriction that is subjected to the sheet material specification; On the other hand, can avoid lip to produce stress and concentrate and the crack effect, can effectively avoid the lip cracking.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the embodiment of the invention, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain other accompanying drawings according to these accompanying drawings.
The structural representation of the hydraulic support back timber lip of the anti-cracking that Fig. 1 provides for the embodiment of the invention;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on embodiments of the invention, those of ordinary skills belong to protection scope of the present invention not making the every other embodiment that is obtained under the creative work prerequisite.
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
Anti-cracking hydraulic support back timber lip of the present invention, its preferable specific embodiment is:
Comprise that the identical plate of two-layer shape is superimposed, and is welded into integral body between the two-ply.The gross thickness of this lip can be 100～120mm.The thickness of two-ply can be identical.
Specific embodiments of the invention, as shown in Figure 1 and Figure 2:
Lip adopts double panel structure, wherein opens border groove 3 on top plate 1, and is with filling and leading up weldering that top plate 1 and lower plywood 2 is welded together.Like this, strengthened the thickness of labial lamina on the one hand, made the gross thickness of lip not be subjected to the restriction of sheet metal thickness; On the other hand, can avoid lip to produce stress and concentrate and the crack effect, can effectively avoid the lip cracking.Can reach well anti-and tear effect, improve the reliability of support greatly.
The thickness of lip can be selected 100～120mm in the specific embodiment, fills and leads up weldering by the border and can realize the lip thickening, has simple and practical characteristics, should guarantee weldquality in welding process, and the tensile strength of weld seam must be higher than mother metal.Improved the ability of lip tear-proof.
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.
Claims (3)
1. an anti-cracking hydraulic support back timber lip is characterized in that, comprises that the identical plate of two-layer shape is superimposed, and is welded into integral body between the two-ply.
2. anti-cracking hydraulic support back timber lip according to claim 1 is characterized in that the gross thickness of this lip is 100～120mm.
3. anti-cracking hydraulic support back timber lip according to claim 3 is characterized in that the thickness of two-ply is identical.
