Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole manual and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 1 to Figure 3, a kind of embodiment according to the specific embodiment of the invention is: a kind of expansion type roof bolt, it comprises anchor sleeve 1, the body of rod 2 and hold-down mechanism, and the bottom of anchor sleeve 1 is circumferentially provided with several open slots 11, and the lower end of anchor sleeve 1 is run through in the lower end of open slot 11; Preferably, the bottom of anchor sleeve 1 is circumferentially provided with several open slots 11 equably, thus the lower end of anchor sleeve 1 is outwards strutted equably.The body of rod 2 is sheathed in anchor sleeve 1, the two ends up and down of the body of rod 2 are respectively to the extension of anchor sleeve 1, the lower end of the body of rod 2 is the anchor pole head 21 of a tapered shape, anchor pole head 21 increases from top to bottom gradually, and the diameter on the top of anchor pole head 21 is greater than the aperture of anchor sleeve 1, when anchor pole head 21 upwards promotes, it just can strut the lower end of anchor sleeve 1 from open slot 11.Top and the anchor sleeve 1 of the body of rod 2 are threaded connection, and the upper end of anchor sleeve 1 is provided with a nut 12, and the top of the body of rod 2 is provided with the external screw thread corresponding with nut 12, just can control anchor pole head 21 be inserted in anchor sleeve 1 by the rotation body of rod 2.Preferably, also comprise the anchor pole cap 22 that is arranged at the upper end of the body of rod 1, rotate the body of rod 2 to facilitate.Hold-down mechanism is arranged at the upper end of the body of rod 2, and hold-down mechanism can be pressed on the surface of side slope.Preferably, hold-down mechanism comprises pin 3 and spring 4, several pins 3 are circumferentially arranged at the top of the body of rod 2, and the upper end of each pin 3 and the upper articulation of the body of rod 2, each pin 3 is also connected with the body of rod 2 by a spring 4, the upper end of junction lower than corresponding pin 3 of each spring 4 and the body of rod 2 and the hinged place of the body of rod 2.Preferably, four pins 3 are circumferentially arranged at the top of the body of rod 2 equably.The structure of hold-down mechanism is simple, easy to use.
Guide hole is beaten in position first suitable in side slope during construction, then, as shown in Figure 3, iron net 5 is layed in side slope, again the present invention is inserted in guide hole through entirety after the mesh of iron net 5, pin 3 struts, and under the effect of spring 4, iron net 5 is pressed in side slope surface.Finally, as shown in Figure 2, rotating the body of rod 2 makes anchor pole head 21 be inserted in anchor sleeve 1, thus make the bottom of anchor sleeve 1 softened with the lower end being pressed on guide hole along open slot 11, the present invention is just overall to be fixed in the guide hole of side slope, although now the body of rod 2 entirety can promote, but pin 3 still can be fitted in securely on iron net 5 under the effect of spring 4, to keep iron net 5 to be stably pressed in face, side slope limit, thus reach anchor sleeve 1, the body of rod 2, iron net 5 and side slope and have face to form firm integral structure, to improve breakout capacity.
