Abstract
The utility model discloses a support deviation control device for a tunnel. The support deviation control device comprises a base, wherein an adjusting beam is arranged on the side part of the base; the adjusting beam is connected with the base through a lifting jack and a connecting rod mechanism. When the tunnel is uneven, the adjusting beam is arranged on the inclined side of the base, then the lifting jack is controlled, the height difference of the left and right sides of the base is adjusted so as to offset the inclined angle of the bottom plate of the tunnel, and the base is adjusted to be in a horizontal state; and therefore, the whole hydraulic support restores to be in a vertical state, the support is prevented from falling, and the support effect on a tunnel roof is greatly improved.
Description
Technical field
The utility model relates to a kind of tunnel support slope-preventing device.
Background technology
Excavation support comprises base at present, base is connected with back timber by column and linkage, the governor motion that the various complex situations that support not may not occur with roadway floor adapt, to such an extent as to existing front and rear monolithic advance timbering is relatively poor to the situation compliance of tunnel roof and floor injustice, when meeting the abominable situation of roadway floor, support easily tilts and makes support connect the top perpendicular to top board, is unfavorable for effective management of support state-maintenance and tunnel roof and floor.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly guarantees that in the situation that runs into tunnel roof and floor injustice excavation support also can the vertical working top board connects the support slope-preventing device on top.
For solving the problems of the technologies described above, the utility model comprises base, and its design feature is that described base sidepiece is provided with the adjusting beam, regulates beam and is connected with base with linkage by jack.
After adopting said structure, run into the uneven situation in tunnel, in the base inclined side adjusting beam is set, then control jack, difference in height about adjusting base is adjusted to level with base, thereby makes whole hydraulic support recover vertical state to offset the inclination angle of roadway floor, avoided support tilt, simultaneously the supporting effect of back improved greatly.
The described base left and right sides is equipped with the adjusting beam, realizes the bilateral adjusting of the base left and right sides, prevents riding, improves the compliance of support.
Described each regulate jack on beam and linkage and be two and be symmetrical arranged regulating beam along regulating the beam length direction respectively, two groups of jack can increase thrust.
Described jack is arranged on the two ends of regulating beam, better adjusting base level.
Described adjusting Liangqi length direction two ends are the sled shape, reduce to move the frame resistance.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the tunnel comprises base 1 with the support slope-preventing device, and base 1 sidepiece is provided with when using take the adjusting beam 2 of roadway floor as supporting, be preferably in base 1 left and right sides adjusting beam 2 all is set, realize base 1 left and right sides bilateral adjusting, prevent riding, improve the compliance of support.Regulate on the beam 2 and be hinged with jack 3 and linkage 4, jack 3 and linkage 4 are hinged with the hinged ear seat 5 of the reliable jack of intensity and the rod hinge connection ear seat 6 that are arranged on the base 1 respectively, thereby adjusting beam 2 is connected with base 1.Linkage 4 is the stabilizing mechanism of jack 3, can offset lateral force and prevent jack 3 lateral deviations.Each is regulated jack 3 on beam 2 and linkage 4 and is two and be symmetrical arranged regulating beam 2 along regulating the beam length direction respectively, and two groups of jack can increase thrust, and jack 3 is arranged on the two ends of regulating beam 2, better adjusting base 1 level.Regulating beam 2 its length direction two ends is the sled shape, reduces to move the frame resistance.
Run into the uneven situation in tunnel, the jack 3 of control base 1 both sides, the difference in height of adjusting base about 1 is to offset the inclination angle of roadway floor, base 1 is adjusted to level, thereby make whole hydraulic support recover vertical state, avoided support tilt, simultaneously the supporting effect of back improved greatly.
The utility model has realized that support left and right sides bilateral independently regulates, and prevents riding, has improved the compliance of support, can also be at any time according to the state of tunnel roof and floor, regulate the support oneself state adapting to the complex work condition, and the utility model is simple and reliable for structure, easy accessibility.Wherein regulating beam 2, jack 3 and linkage 4 is the absolute construction that depend on base 1, installs when running into the abominable situation of tunnel roof and floor, and can remove easily when tunnel roof and floor situation is better.
