Description
Technical field
The utility model relates to a kind of hydraulic support, relates 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 be subjected to 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 utility model provides a kind of whole top beam hydraulic rack that contains extensible canopy, and this deckle board of whole back timber that contains extensible canopy is more solid, durable.
The purpose of this utility model is achieved through the following technical solutions:
The whole top beam hydraulic rack that contains extensible canopy of the present utility model, the front end of back timber is provided with deckle board, the two ends of described deckle board are respectively equipped with stiffener, described stiffener has gap, the end of described deckle board is inserted in the described gap, and at described opening position that described stiffener and the welding of described deckle board is fixing.
The technical scheme that is provided by above-mentioned the utility model as can be seen, the whole top beam hydraulic rack that contains extensible canopy that the utility model embodiment provides, because the two ends of the deckle board of back timber front end are respectively equipped with stiffener, stiffener has gap, the end of deckle board is inserted in the described gap, and at opening position that described stiffener and the welding of described deckle board is fixing.Carry out structure design by the place that crushes easily most and tear at deckle board, effectively raise the intensity of back timber deckle board, make deckle board more solid, durable, greatly reduce the possibility of damage.

The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills belong to protection domain of the present utility model 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 utility model, its preferable specific embodiment is:
The front end of back timber is provided with deckle board, and the two ends of described deckle board are respectively equipped with stiffener, and described stiffener has gap, and the end of described deckle board is inserted in the described gap, and at described opening position that described stiffener and the welding of described deckle board is fixing.
Described stiffener can be the thick steel plate of 40～60mm, is the thick steel plate of 50mm such as stiffener.
The lower end of described stiffener can be used as the anti-cutting piece of described back timber front end.
About 18X45 ° groove can be opened in the front of described stiffener and base, and the groove of about 20X70 can be opened in the back of described stiffener.
This hydraulic support can be two column protected type support or four post support shield type support.The front end of described 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 utility model, at the front end of back timber, the thick steel plate of 50mm is respectively welded in the both sides of deckle board, and (thickness of steel plate can be adjusted according to concrete design, is generally 40～60mm) weak parts that encase deckle board.Simultaneously, increase the thickness of deckle board and the width of outer rim as far as possible, improve self intensity.Carry out structure design by the place that crushes easily most and tear at deckle board, effectively raise the intensity of back timber deckle board, make deckle board more solid, durable, greatly reduce the possibility of damage.
Specific embodiment, extremely shown in Figure 5 as 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 was subjected to the pressure F of top board, for deckle board 3, its weak link was mainly at 6 places, pressurized turning, both sides.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 18X45 ° groove is opened on stiffener 2 fronts and base, avoids stiffener 2 seamed edges to hurt sb.'s feelings the thickness that weakens simultaneously, good looking appearance; Groove long about 20X70 is opened in stiffener 2 back, and purpose is " to sting frame " between left and right in the process of trying to stop people from fighting each other.
The weak link of deckle board 3 is mainly at 6 places, pressurized turning, both sides, and the encirclement through stiffener 2 is strengthened this weak link, makes 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 utility model, 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 utility model is simple in structure, is convenient to implement, and the intensity height, good reliability is particularly useful for having in the hydraulic support of integral top beam of built-in extensible canopy.
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.
