Abstract
The utility model discloses movable side guard plates on two sides of high inclining-angle support. The movable side guard plates on the two sides of the high inclining-angle support comprise a top beam. Two side of the top beam are respectively provided with a movable side guide plate. Movable side guide plates on the two sides are provided with a two-head telescopic jack. The middle of the two-head elastic jack is fixed below the middle of the top beam. Two ends of the two-head telescopic jack are respectively connected with the movable side guide plates on the two sides. The left telescopic head of the two-head telescopic jack and the right telescopic head of the two-head telescopic jack are respectively provided with a single hydraulic connector. The movable side guide plates on the two sides can be separately controlled, spaces used for fixing the jack can also be reduced and force conditions of a fixed pin of the jack can also be greatly improved. The movable side guard plates on the two sides of the high inclining-angle support are particularly applied to a hydraulic support of a high inclining-angle work surface.
Description
Technical field
The utility model relates to a kind of bilateral activity side guard board, relates in particular to a kind of high inclination-angle support bilateral activity side guard board.
Background technology
As shown in Figure 1, at present, in coal mine underground hydraulic support frame, the form of structure of controlling separately the bilateral activity side guard board is that a thruster jack is respectively installed in both sides, to realize controlling the separately bilateral activity side guard board.
The shortcoming that said structure all exists is:
Fixedly the used space of jack is large, causes the stroke of side guard board to reduce; The jack steady pin is stressed large, fragile.
The utility model content
The purpose of this utility model provides that the used space of a kind of fixedly jack is few, the high inclination-angle support bilateral activity side guard board of jack steady pin reasonable stress.
The purpose of this utility model is achieved through the following technical solutions:
High inclination-angle support bilateral activity side guard board of the present utility model, comprise back timber, the both sides of described back timber are respectively equipped with movable side protection plate, the movable side protection plate of both sides is provided with the Double-head telescopic jack, the middle part of described Double-head telescopic jack is provided with fixing hole, this fixing hole be fixed on by steady pin described back timber the middle part below, the two ends of described Double-head telescopic jack are connected with the movable side protection plate of both sides respectively, and left telescopic head and the right telescopic head of described Double-head telescopic jack are respectively equipped with independent hydraulic interface.
Can be found out by the technical scheme that above-mentioned the utility model provides, the high inclination-angle support bilateral activity side guard board that the utility model embodiment provides, because the movable side protection plate of both sides is provided with the Double-head telescopic jack, following, two ends that the middle part of Double-head telescopic jack is fixed on the middle part of back timber are connected with the movable side protection plate of both sides respectively, and left telescopic head and the right telescopic head of Double-head telescopic jack are respectively equipped with independent hydraulic interface.Can realize that the movable side protection plate of both sides controls separately, can reduce again the fixedly used space of jack, and can greatly improve the force-bearing situation of jack steady pin.
Description of drawings
Fig. 1 is the structural representation of the bilateral activity side guard board of prior art;
Structural representation a, the b of the high inclination-angle support bilateral activity side guard board that Fig. 2 a, Fig. 2 b provide for the utility model embodiment;
Fig. 3 is the structural representation of Double-head telescopic jack among the utility model embodiment;
Fig. 4 is the fluid pressure line schematic diagram of Double-head telescopic jack among the utility model embodiment.
Among the figure: 1, back timber, 2, movable side protection plate, 3, thruster jack of the prior art, 4, guide rod, 5, Double-head telescopic jack of the present invention, 6, fixing hole, 7, steady pin.
The specific embodiment
The below will be described in further detail the utility model embodiment.
High inclination-angle support bilateral activity side guard board of the present utility model, the specific embodiment that it is better such as Fig. 2 a, shown in Figure 3:
Comprise back timber, the both sides of back timber are respectively equipped with movable side protection plate, the movable side protection plate of both sides is provided with the Double-head telescopic jack, the middle part of described Double-head telescopic jack is provided with fixing hole, this fixing hole be fixed on by steady pin described back timber the middle part below, the two ends of described Double-head telescopic jack are connected with the movable side protection plate of both sides respectively, and left telescopic head and the right telescopic head of described Double-head telescopic jack are respectively equipped with independent hydraulic interface.
Shown in Fig. 2 b, described movable side protection plate can be connected with guide rod, and the outer end of described Double-head telescopic jack is connected with described guide rod.
Described Double-head telescopic jack can be that the middle part is piston rod for cylinder body, two ends, or also can be that the middle part is cylinder body for piston rod, two ends.
High inclination-angle support bilateral activity side guard board of the present utility model, the jack of employing is the Double-head telescopic jack, namely, the bilateral side guard board is controlled by a jack, the jack middle part is provided with a fixing hole, and the centre is fixed by a steady pin, and left and right sides telescopic head has the liquid interface that advances back separately.Can adopt jack to pass through hinged guide rod control side guard board, also can adopt the mode that directly links to each other with side guard board after lengthening at the bottom of the jack cylinder to control.
As shown in Figure 4, the Double-head telescopic jack can be by the control of double hydraulic control reversible lock, to guarantee the anti-down effect of high inclination-angle bracket side backplate.Control mouthful can with fall frame and move frame interlock, conveniently to move frame.
Its advantage is: reduce the fixedly used space of jack, strengthened the stroke of side guard board, strengthen the change width scope of set cap; Support is in application process, and the support left and right sides is stressed to be acted on the jack, and for the jack steady pin, the power of left and right directions is cancelled out each other to a certain extent, has improved the force-bearing situation of jack steady pin.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; 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.
