Abstract
The utility model discloses a combined support, which comprises a top beam, a front connecting bar and a rear connecting bar, wherein the front connecting bar and the rear connecting bar arranged under the top beam can slide along the top beam. The front connecting bar is fixedly connected with the rear connecting bar via a cylinder body of an advancing cylinder, and the top beam is hinged to the head portion of a piston rod. The adjacent front connecting bar and the rear connecting bar are hinged via corner links, thereby integrally connecting the front connecting bar and the rear connecting bar on all working faces. The combined support has high integrality, high adaptability, and strong stability and fast moving, not only can perform full-seam mining but can be used to top-coal caving without flooring, which is a combined support between a fully-mechanized mining support and a cantilever support.

There is following shortcoming at least in above-mentioned prior art:
Suspended back timber class set cap supporting area is little, easy sideslip, need are spread the top net when moving frame; Fully mechanized mining supporter weight is big, cost is high, be not suitable for middle-size and small-size mine uses.
The utility model content
The purpose of this utility model provides a kind of good integrity, compliance is strong, stability is high, move sectional shelf-unit efficiently.
The purpose of this utility model is achieved through the following technical solutions:
Sectional shelf-unit of the present utility model comprises back timber, and the below of described back timber is provided with front rod, back link, fixedlys connected by the cylinder body that advances oil cylinder between described front rod and the back link, and the piston rod head of described back timber and described propelling oil cylinder is hinged.
The technical scheme that provides by above-mentioned the utility model as can be seen, sectional shelf-unit described in the utility model owing to fixedly connected by the cylinder body that advances oil cylinder between front rod and the back link, back timber is hinged with the piston rod head of propelling oil cylinder.By advancing oil cylinder to promoting comprehensively between back timber and front rod and the back link, good integrity, compliance is strong, stability is high, move fast during application.
Description of drawings
Fig. 1 is the structural representation of sectional shelf-unit of the present utility model;
Fig. 2 is the A-A place sectional view of Fig. 1;
Fig. 3 is the cross-sectional schematic at the front rod place of the utility model application state;
Fig. 4 is the schematic top plan view of the utility model application state.
The specific embodiment
Sectional shelf-unit of the present utility model, its preferable specific embodiment comprises back timber 1 as shown in Figure 1, back timber 1 supports by hydraulic prop 7.
The below of back timber 1 is provided with front rod 2, back link 4, fixedlys connected by the cylinder body that advances oil cylinder 3 between front rod 2 and the back link 4, and back timber 1 is hinged with the piston rod head that advances oil cylinder 3.By advancing the effect of oil cylinder 3, can make relative motion between back timber 1 and front rod 2 and the back link 4, since fixedly connected between front rod 2 and the back link 4 by the cylinder body that advances oil cylinder 3, can promote comprehensively.
The middle part that specifically can make the cylinder body that advances oil cylinder 3 pass front rod 2 is also fixed; Fixedlying connected with back link in the rear end of cylinder body, specifically can make the rear end of cylinder body pass the middle part of back link 4, and clamp 6 be snapped in the draw-in groove of rear end of the cylinder block, by bearing pin 5 clamp 6 is fixed on the back link 4 afterwards.
As shown in Figure 2, the below of back timber 1 vertically is provided with chute 10, and the corresponding site of front rod 2 and back link 4 is respectively equipped with slide plate 9, and slide plate 9 is inserted in the chute 10, and front rod 2 can be slided by relative back timber 1 with back link 4.
The two ends of front rod 2 and back link 4 are respectively equipped with hinge hole 11, are used for being connected with adjacent front rod 2 or back link 4.
As shown in Figure 3, back timber 1 has many, and the below of every back timber 1 is respectively equipped with front rod 2, back link 4, connects by angle shape rod 8 respectively between the front rod 2 of adjacent two back timber 1 belows and between the back link 4.The two ends of angle shape rod 8 are hinged with the end of adjacent front rod 2 or back link 4 by hinge 12 respectively.
Hinge 12 is inserted in the hinge hole 11 of end of front rod 2 or back link 4, and hinge hole 11 can be the prolate hole, makes hinge 12 that certain activity can be arranged therein.Can be connected with tension spring between hinge 12 and front rod 2 or the back link 4, certain buffering is carried out in the activity of hinge 12.
Below use principle of the present utility model is described in detail:
As shown in Figure 4, and with reference to Fig. 3, during use, at first sectional shelf-unit is arranged successively at work plane, hydraulic prop 7 is carried out fluid injection to be made it to raise, back timber 1 is supported on the roof, with angle shape rod 8 the adjacent stent front and rear connecting rods is coupled together respectively then, thereby makes each frame sectional shelf-unit connect into whole support apparatus on the work plane.Behind the working face mining, when needing the reach sectional shelf-unit, operating procedure is as follows:
The utility model by front and rear connecting rods with advance being connected of oil cylinder, angle shape rod and front-rear linkage flexible joint make support form an integral body, move fast, be difficult for sideslip, can adapt in the big work plane of high inclination-angle, soft seat, pressure to use.The supporting area is big, good integrity, compliance is strong, stability is high, in light weight, but both full-seam mining, but also the not lapping of caving coal is used, and is a kind of a kind of sectional shelf-unit between fully mechanized mining supporter and cantilever support.
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.
