Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figures 1 to 4, a kind of inclined shaft presses joint roof control device, including 2 He of active support mechanism with multiple allow
Passive protecting mechanism 1, passive protecting mechanism 1 include a pair of of X-type bracket, a pair of of first crossbeam 13 and multiple second cross beams 14, X-type
Bracket includes frame leg 10 and clamping screw 100, and the middle part of a pair of of frame leg 10 is locked connection by clamping screw 100, and two
Frame leg 10 is in X-type cross structure, and frame leg 10 includes upper section frame leg 12 and lower section of frame leg 11, and lower section frame leg 11 is equipped with lumen, above section
Frame leg 12, which is inserted, is locked upper section frame leg 12 and lower section of frame leg 11 by least one caging bolt 111 into lumen, on this section
Frame leg 12 is equipped with multiple horizontal limited posts 121 for running through its ontology, and multiple limited posts 121 are located at the top of lumen, and along upper
It cuts 12 extending direction of frame leg to be arranged successively, the upper end that frame leg 12 is cut in a pair is articulated with 13 lower end of first crossbeam and connects X-type bracket
It connects and is connected with first crossbeam 13, by hinged form, can be adapted for the tunnel top 1a with different gradients, two X-types
A first crossbeam 13 is respectively provided on bracket, first crossbeam 13 is equipped with multiple mounting grooves 131, and multiple second cross beams 14 match
Insertion be located at X-type bracket on first crossbeam 13 mounting groove 131 in, first crossbeam and second cross beam are mutually perpendicular to, with X-type branch
Frame constitutes group frame, i.e. passive protecting mechanism 1, is equipped on first crossbeam 13 and second cross beam 14 multiple through respective ontology
Mounting hole 150, active support mechanism 2 includes metal mesh 22 and multiple anchor poles 21, and metal mesh 22 is layed in 13 He of first crossbeam
The upper end of second cross beam 14, and abutted against with top surface on tunnel, after multiple anchor poles 21 sequentially pass through mounting hole 150 and metal mesh 22
It protrudes into inside the 1a of tunnel top.
Tunnel is come after pressing, and when X-type support force reaches a timing, the clamping screw generation of lower section frame leg and upper section frame leg is broken
It splits, above cuts frame leg and move down, the limited post on upper section frame leg can be abutted with lower section of frame leg, realized barrier effect, made
Again stress continues to play supporting role frame leg, therefore X-type bracket has effective supporting construction, thus complete it is primary allow pressure,
When X-type support force reaches a timing again, limited post fracture, the other limited post being positioned above, which is realized, to be stopped, and makes to prop up
Frame has effective supporting construction, thus complete it is secondary allow pressure, and so on, this leg is sustainable to play supporting role again,
Make X-type bracket that can realize the multiple pressure function that allows；Anchor pole and metal mesh can be with the pressure at the top of active undertaking and dispersion tunnel, therefore
" passive and active " supporting association control top is realized by X-type bracket, anchor pole and metal mesh, and the installation of X-type bracket solves inclination lane
The stability problem of road bracket realizes repeatedly allowing for bracket and presses the effectiveness of roof control.
The vertical section of second cross beam 14 is W type.
The number of second cross beam 14 is two to four, can be according to for the shape and structure determination second cross beam that tunnel is pushed up
Number generally uses two second cross beams, the mounting groove being respectively arranged in above the hinged place for cutting frame leg and first crossbeam
In, it can preferably support and load-bearing.
The upper surface flush of first crossbeam 13 and second cross beam 14, can by metal mesh it is smooth be placed in first crossbeam
With second cross beam upper surface.
The side wall of the upper lateral wall for cutting frame leg 12 and lumen abuts against, and during supporting and allowing pressure, above cuts frame leg under
Relative displacement will not be occurred in the horizontal direction by cutting between frame leg, can avoid shaking, and have the function of mutually stablizing support.
The number of caging bolt 111 is two, can lock and cut frame leg and lower section of frame leg, realizes the firm installation of the two.
The horizontal axis of limited post 121 is parallel with the horizontal axis of caging bolt 111.
Limited post 121 is cylindrical body, and number is two to four, through-hole can be arranged on upper section of frame leg, by limited post
It penetrates；But the also stud bolt on upper section of bracket makes bolt play the barrier effect of limited post.
Mounting means:
Multiple mounting holes to match with anchor pole are set on first crossbeam and second cross beam, it is first before the installation of X-type bracket
The anchor pole active support on tunnel top is first carried out, then metal mesh is laid in the upper surface of first crossbeam and second cross beam, X-type is installed
Bracket makes anchor pole pass through metal mesh and mounting hole, and is tightened by bolts in anchor pole lower end in first crossbeam and second cross beam installation
Lower section of frame leg of hole lower end, X-type bracket should be inserted into inclined shaft bottom 1b, thus formed " actively+passive " supporting association control top, X
Type bracket has the function of repeatedly to allow pressure, and which solves the stability problems of inclined shaft bracket, realize the more of X-type bracket
The secondary pressure the effectiveness of roof control that allows.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
