Further, described first telescoping mechanism includes expansion link, expansion screw or hydraulic cylinder.
Further, described second telescoping mechanism includes jack, expansion screw or expansion link.
Further, the cross section both sides of described fixing beam are arc.
Further, described fixing beam is provided with limited block.
Further, described fixing beam is straight beam or bending beam; When described fixing beam is bending beam, the angle of bending part is obtuse angle.
Further, described fixing beam is monoblock type or multi-section combined.
Further, described chain is single-stranded loop or many chain links.
Further, described support also includes the hydraulic control system for controlling jack.
The beneficial effects of the utility model are as follows:
1. support described in the utility model adopts chain and connecting pin to be connected with fixing beam, connects reliable, and the gap of adjacent stent can control in set point, it is prevented that occur that excesssive gap causes cradle top leakage cash to hurt sb.'s feelings; It addition, when a certain support in work needs to remove or change, only remove the chain being connected with this support, greatly facilitate the working service of support;
2. the walking beam of support described in the utility model can adjust with the angle of fixing beam, to better adapt to the Coal Seam Thickness Change of work surface; It addition, walking beam can also be used to carry out putting coal at support afterbody, improve the response rate of coal further;
3, the fixing beam body of support described in the utility model also is able to be combined by multiple fixing beams, to alleviate the weight of single hop beam body in transportation, reduces the labor intensity of workman;
Support described in the utility model effectively overcomes the defect of existing girder steel support, and safety in production and high-yield and high-efficiency for work surface provide effective guarantee.

Detailed description of the invention
In order to be illustrated more clearly that this utility model, below in conjunction with preferred embodiments and drawings, this utility model is described further.
As shown in Fig. 1, Fig. 6, described support includes guide beam 1, fixing beam 5 and walking beam 8, and guide beam 1 is hinged with one end of fixing beam 5, and one end of walking beam 8 is hinged with the other end of fixing beam 5; Guide beam 1, fixing beam 5 are hinged with the two ends of the first telescoping mechanism respectively, by changing the length of the first telescoping mechanism, the angle that can make guide beam 1 and fixing beam 5 changes, make guide beam 1 consistent with the inclination angle of top board, the first telescoping mechanism between guide beam 1 and fixing beam 5, can also be not provided with; First telescoping mechanism can be selected for expansion link 2, expansion screw or hydraulic cylinder;Owing to half-edge coal seam angle is typically larger than 40 degree, thus the angular range between guide beam 1 and fixing beam 5 is generally between 45 ��-90 ��. Fixing beam 5, walking beam 8 are hinged with the two ends of the second telescoping mechanism respectively, and the second telescoping mechanism can select jack 7, expansion screw or expansion link; Along with elongating or shortening of the second telescoping mechanism, walking beam 8 can swing relative to fixing beam 5, and walking beam 8 bottom is close to or away from guide beam 1, so that described support adapts to the different coal thickness situation of work surface; When the second telescoping mechanism is jack structure, described support is additionally provided with hydraulic control system 6, hydraulic control system 6 and jack 7 pipeline and connects, and can control elongating or shortening of jack 7 by hydraulic control system 6.
As in figure 2 it is shown, be provided with many chains 3 on fixing beam 5, chain 3 is connected with fixing beam 5 by connecting pin 4; In real work face, the fixing beam 5 of adjacent stent links together each through chain 3 and connecting pin 4, and owing to chain 3 has the degree of freedom of multiple directions, therefore, all supports linked together are the formation of the shielding system with certain flexibility.
As shown in Figure 3, in order to prevent adjacent stent from not card phenomenon occurring, the cross section both sides of fixing beam 5 are arc, simultaneously in order to limit the gap of adjacent stent, fixing beam 5 can also arrange limited block 10, to control the gap between adjacent stent, in the present embodiment by the clearance control between adjacent stent in 0-20mm distance.
As shown in Figure 4, described support when real work, the top plate contact of guide beam 1 and work surface, the bottom of walking beam 8 and the contacts baseplate of work surface, described support and coal body together form a safe space, produce normally for work surface; Described support is without moving frame mechanism, and after the coal body of guide beam 1 with bottom, walking beam 8 bottom is plucked out of, described support automatically moves down under the effect of self gravitation and goaf, top spoil gravitational load.
It is the partial enlarged drawing that in Fig. 1, the first telescoping mechanism 2 selects Telescopic rod structure as shown in Figure 5.
The fixing beam 5 of described support can be monoblock type can also be multi-section combined, can increase the supporting seat for assisting support on fixing beam 5.
Obviously; above-described embodiment of the present utility model is only for clearly demonstrating this utility model example; and it is not the restriction to embodiment of the present utility model; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here cannot all of embodiment be given exhaustive, every belong to apparent change that the technical solution of the utility model extended out or the variation row still in protection domain of the present utility model.
