Abstract
The utility model discloses a telescopic beam structure, and belongs to the field of mining machinery. The telescopic beam structure comprises a top beam body, as well as a telescopic beam body which is arranged inside the top beam body and can perform telescopic movement along the top beam body; a side protection beam and a side protection beam jack are arranged inside the telescopic beam structure; the side protection beam jack can push the side protection beam to move in the direction perpendicular to the telescopic beam body; under the action the side protection beam jack, the side protection beam can extend outwards to elongate the width of the telescopic beam body, so as to enlarge the area of the telescopic beam, reduce the exposed area of the top board, and avoid damage on an operating personnel due to fallen rock.
Description
Technical field
The utility model relates to the coal-cutting machinery technical field, is specifically related to a kind of support frame.
Background technology
Rich coal resources in China, the fully-mechanized mining equipment maturation, coal winning technology is gradually improved, in short supply along with the energy, the quickening day by day of coal in China exploitation paces, the coal mining safety problem is also just more and more outstanding.In current mining operations, the fully-mechanized coalface hydraulic support has obtained applying more widely.In order to improve the supporting area, guarantee construction operation personnel's safety, existing hydraulic support has part that extensible canopy can be set on back timber.Hydraulic support with extensible canopy can stretch out extensible canopy when being necessary in back timber, plays top board is played to the temporary lining effect, so as in specific operation situation, enlarging and pay area.
But current extensible canopy design usually is by back timber inside, along the back timber direction, stretches out.Due to the inside that is arranged on back timber, the width of extensible canopy will certainly be narrower than back timber, therefore can cause the supporting width of extensible canopy to be less than back timber, and then the supporting space occur, causes spoil to drop and may injure operating personnel's safety problem by a crashing object.
The utility model content
In order to improve the safety of coal mining coal mining activity, realize the seamless supporting of back timber on the basis of existing extensible canopy structure, the utility model provides a kind of support frame with the extensible canopy structure.
The disclosed support frame of the utility model, comprising the back timber body and be arranged on back timber body inside also can be along the extensible canopy body of described back timber body stretching motion, also be provided with the side guard beam in described extensible canopy body and for promoting the side guard beam jack of described side guard beam, at described extensible canopy body, be contracted under the state in the back timber body, described side guard beam is contained in described extensible canopy body inside, under the state stretched out from the back timber body at described extensible canopy body, it is laterally protruding from described extensible canopy body that described side guard beam jack can promote described side guard beam.
The disclosed support frame of the utility model is provided with two side guard beams and corresponding side guard beam jack in described extensible canopy body, and described two side guard beams move in the opposite direction.
The disclosed support frame of the utility model, described side guard beam is body structure.
The disclosed support frame of the utility model, described side guard beam, under the state outwards crossed out, can cover the gap between the extensible canopy body of the extensible canopy body of described support frame and adjacent support frame.
The disclosed support frame of the utility model, described side guard beam stretch out direction perpendicular to described extensible canopy body.
The beneficial effect of the technical scheme that the utility model provides is:
The side guard beam of support frame is the width of horizontal spreading increase extensible canopy body outwards, and then the area of expansion extensible canopy, cover the extensible canopy of this support frame and the gap between adjacent support frame extensible canopy body, reduce the bare area of top board, finally can realize avoiding the leak purpose of cash to operating personnel's injury.
The accompanying drawing explanation
Fig. 1 is the structural representation of the extensible canopy structure of the support frame that provides of the utility model embodiment in deployed condition;
Fig. 2 is the structural representation of the extensible canopy structure of the support frame that provides of the utility model embodiment at contraction state;
Fig. 3 is extensible canopy structure extensible canopy body and the side guard beam partial structurtes schematic diagram of the support frame that provides of the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1 to Figure 3, the extensible canopy structure of the utility model support frame can realize on existing extensible canopy basis.Support frame of the present utility model is except the basic structure with existing support frame, also comprise novel extensible canopy structure, its extensible canopy structure mainly comprise back timber body 1, can be along extensible canopy body 2, side guard beam and the side guard beam jack of back timber body stretching motion.
Inside at extensible canopy body 2 also is provided with side guard beam 3.Side guard beam 3 also adopts body structure usually.Side guard beam 3 is slightly less than extensible canopy body 2 in the length along extensible canopy body 2 directions; Side guard beam 3 guarantees can slightly be wider than the extensible canopy body when side guard beam 3 stretches out extensible canopy body 2 with the transverse width of extensible canopy body 2, so just can guarantee between back timber not stay gap.
The motion of side guard beam 3 promotes by side guard beam jack 4.Side guard beam jack 4 is arranged on extensible canopy body 2 inside, the motion of side guard beam jack 4 can promote side guard beam 3 with extensible canopy body vertical direction on moved.
All be narrower than back timber body 1 due to extensible canopy body 2 with both sides, therefore the side guard beam jack 4 of the side guard beam 3 in extensible canopy body 2 and promotion side guard beam 3 is bi-directional symmetrical settings, both extensible canopy body 2 interior arrange respectively two can be horizontal along extensible canopy body 2 vertical direction do the side guard beam 3 of reverse motions, each side guard beam 3 promotes by side guard beam jack 4 independently.Can guarantee like this that when needed side guard beam 3 can be the direction vertical with extensible canopy body 2 relative expansion the to two ends respectively.
The extensible canopy structure of support frame of the present utility model is provided with side guard beam 3 in extensible canopy inside, under the promotion of side guard beam jack 4, side guard beam 3 can outwards launch to increase the width of extensible canopy body 2, and then the area coverage of expansion extensible canopy body, reduce the bare area of top board, finally can realize avoiding the leak injury of cash to the operating personnel.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (5)
