The integral ejecting beam hydraulic bracket effectively increases the strength of the frame plate of the ejecting beam through the structural design at the most easily damaged and torn position so that the frame plate is firmer and more durable and the possibility of damage is greatly reduced.
Description
Technical field
The present invention relates to a kind of hydraulic support, relate in particular to a kind of whole top beam hydraulic rack that contains extensible canopy.
Background technology
Current, the employed hydraulic support of each big coal mine fully-mechanized mining working of China, its back timber is many all to be the pattern that overall structure contains built-in extensible canopy.For the back timber of this kind structural shape, the deckle board of its front end is a part that is damaged by pressure by the extensible canopy of institute's load-bearing easily (basic pressure is to come from top board), and in case damage just is difficult to reparation.Particularly for the hydraulic support of high workload resistance, this kind phenomenon is more general.
And owing to receive the restriction of back timber structure, deckle board can not design too widely again or too thick self intensity of improving makes it avoid damaging.
Summary of the invention
The purpose of this invention is to provide a kind of whole top beam hydraulic rack that contains extensible canopy, this deckle board of whole back timber that contains extensible canopy is more solid, durable.
The objective of the invention is to realize through following technical scheme:
The whole top beam hydraulic rack that contains extensible canopy of the present invention; The front end of back timber is provided with deckle board, and the two ends of said deckle board are respectively equipped with stiffener, and said stiffener has gap; The end of said deckle board is inserted in the said gap, and at said opening position that said stiffener and the welding of said deckle board is fixing.
Technical scheme by the invention described above provides can be found out; The whole top beam hydraulic rack that contains extensible canopy that the embodiment of the invention provides; Because the two ends of the deckle board of back timber front end are respectively equipped with stiffener; Stiffener has gap, and the end of deckle board is inserted in the said gap, and at opening position that said stiffener and the welding of said deckle board is fixing.Structure design is carried out in place through crushing easily most and tear at deckle board, effectively raises the intensity of back timber deckle board, makes deckle board more solid, durable, greatly reduces the possibility of damage.

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 carried out clear, intactly description, 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.
The whole top beam hydraulic rack that contains extensible canopy of the present invention, its preferable specific embodiment is:
The front end of back timber is provided with deckle board, and the two ends of said deckle board are respectively equipped with stiffener, and said stiffener has gap, and the end of said deckle board is inserted in the said gap, and at said opening position that said stiffener and the welding of said deckle board is fixing.
Said stiffener can be the thick steel plate of 40～60mm, is the thick steel plate of 50mm such as stiffener.
The lower end of said stiffener can be used as the anti-cutting piece of said back timber front end.
About 18 * 45 ° groove can be opened in the front of said stiffener and base, and about 20 * 70 groove can be opened in the back of said stiffener.
This hydraulic support can be two column protected type support or four post support shield type support.The front end of said extensible canopy can not hinged wall supporting or hinged one-level wall supporting or hinged secondary wall supporting.
The whole top beam hydraulic rack that contains extensible canopy of the present invention, at the front end of back timber, the both sides of deckle board respectively weld the thick steel plate of 50mm (thickness of steel plate can be adjusted according to concrete design, be generally 40～60mm) encase deckle board weak part.Simultaneously, increase the thickness of deckle board and the width of outer rim as far as possible, improve self intensity.Structure design is carried out in place through crushing easily most and tear at deckle board, effectively raises the intensity of back timber deckle board, makes deckle board more solid, durable, greatly reduces the possibility of damage.
Specific embodiment, extremely shown in Figure 5 like Fig. 1:
Shown in Fig. 1 a, Fig. 1 b, comprise back timber 1, stiffener 2, deckle board 3, extensible canopy 4.
Shown in Fig. 2, Fig. 3 a, Fig. 3 b, when the front end of extensible canopy 4 received the pressure F of top board, for deckle board 3, its weak link is 6 places, pressurized turning in both sides mainly.The front end of extensible canopy 4 can have wall supporting 5, also can not be with wall supporting 5.
Shown in Fig. 4 a, Fig. 4 b, the about 40～60mm of the thickness of stiffener 2 is behind the open and clear mouth 7; Be attached to set cap 1 front end both sides; The width of gap and the degree of depth depend on the thickness and the height of deckle board 3, and gap 7 wraps in deckle board 2 avris weak links in the stiffener 2, and weld the border.Three limit bevels of gap 7 are filled and led up welding with deckle board 2.About 18 * 45 ° of grooves are opened on stiffener 2 fronts and base, avoid stiffener 2 seamed edges to hurt sb.'s feelings the thickness that weakens simultaneously, good looking appearance; Groove long about 20 * 70 is opened in stiffener 2 back, and purpose is between left and right, in the process of trying to stop people from fighting each other, " to sting frame ".
The weak link of deckle board 3 is 6 places, pressurized turning in both sides mainly, through the encirclement of stiffener 2, make this weak link be able to strengthen, and make deckle board 3 can bear the bigger pressure from extensible canopy 4 and down-hole top board.
As shown in Figure 5, stiffener 2 also has the effect of " anti-cutting piece ".In the back timber of many supports of prior art, in back timber front end specialized designs " anti-cutting piece " arranged through regular meeting, cut set cap 1 to prevent coal mining machine roller 8.
In the concrete hydraulic support of using of the present invention, comprise back timber, extensible canopy.Extensible canopy both can hinged wall supporting, also can not hinged wall supporting, and also can hinged secondary side protecting mechanism; Support both can be the two column protected type pattern, also can be the four post support shield type pattern.
The present invention is simple in structure, is convenient to implement, and intensity is high, and good reliability is particularly useful for having in the hydraulic support of integral top beam of built-in extensible canopy.
The above; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technician who is familiar with the present technique field is 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.
