The support has the characteristics of more reasonable stress, high strength, high bearing capacity, good stability, good supporting effect, easiness in processing and low cost, the whole support does not need bolts, and the workpiece resistance can be 5-6 times that of a common support.
Description
The utility model proposes a kind of metallic support that is used for the roadway support of mine impermanency, i.e. the two-way resistance formula trapezoid support that can contract that increases of i iron.
The sleeve of " the two-way contractibility excavation support of i iron wedge-type connector " that existing Chinese patent CN2095935U proposes adopts stationary structure, and inconvenience is installed, and dismounting owing to can not realize increasing resistance, realizes working resistance by friction.
The purpose of this utility model is to provide a kind of can two-wayly increase resistance and mobilizable formula trapezoid support that contracts.
The utility model is because in the overall process that distortion is contracted, the stressed maintenance of pillar is disalignment not, and support can be avoided the surrouding rock stress peak, make country rock bear the ore deposit and press with support, thus have stressed rationally, intensity is big, supporting capacity is high, good stability, the characteristics that supporting effect is good.Entire bracket need not used bolt, easy frame worker, and the 5-6 of with low cost, the general support of its working resistance is doubly.
The utility model utilizes loose-leaf telescoping structure pilum (2), and one drag device A is housed at pilum (2) position that links to each other with the post (5) of living, the post (5) of living has a pressure regulation device (6) with back timber (10) contact site device, the horizontal sliding component (8) of back timber (10) is one to have the member of drag device B and safety device (7), support all can be contracted in vertical or horizontal direction in the altar resistance, the exhausted major part of concentrated stress can be transferred to the deep of roadway surrounding rock, support is only finished the maintenance to the roadway surrounding rock globality, makes not wall caving of country rock, not roof fall.

1-8 is described in detail the utility model below in conjunction with accompanying drawing.
The utility model is made up of base (1), pilum (2), post (5) alive and back timber (10), pilum (2) adopts the loose-leaf telescoping structure, it by hinge axis (1-2) with pilum (2) but before and after two partly be connected to form an opening and closing structure, make post alive in pilum (2), make stretching motion, and can to limit post alive by the limited block (4) that is fixed with on the post (5) of living be the entire bracket longitudinal deformation amount; A drag device A is equipped with at pilum (2) position (it is interior that pilum 2-1 has a square hole 2-3) that links to each other with the post (5) of living, it is made up of a compression roller (3-2) that is installed on the saddle shaped pressure roller horse (3-3), its integral body is packed in the clip (3-1), and to be 4-8 ° horse wedge (3-4) back by the inclined working of packing into closely contact with a extruding plate (5-2) on being fixed on post alive (5) compression roller (3-2).With back timber (10) contact site one pressure regulation device (6) is housed at the post (5) of living, it is made of a guiding interface (6-2) that is fixed with pressure adjustment axle (6-1), and its overall fixed is on the post (5) of living.Horizontal sliding component (8) on the back timber (10) is one to have the member of drag device B and safety device (7), drag device B is fixed with reinforcement gusset (8-2) by the both sides skin and two end faces are fixed with clip (8-1) formation of strengthening plate washer (8-3), can squeeze in it and increase resistance wedge (8-4), by on increasing resistance wedge (8-4), having security protection pin (7-1) the formation safety device (7) that can insert band protection bolt (7-2) a plurality of apertures (8-5) in, two limited blocks (9) that are equipped with on the back timber (10) but the deformation of timbering amount of limit bracket horizontal direction.
During support work, because adjusting the radial centre lines of axle (6-1), pressure keeps overlapping with stent strut leg (2,5) center line, the pressure of beam portion can only be delivered on the post leg by adjusting axle, be delivered to roadway floor thus, no matter how back timber and post leg angle change, and its pressure can only transmit along post leg center line.When living post (5) when moving downward, can drive extruding plate (5-2) and move together, because extruding plate and compression roller (3-2) force of labor extruding force form the working resistance in the support process of contracting.To increase resistance wedge (8-4) squeezes in the clip (8-1) by hypotenuse, as required security protection pin (7-1) pin is gone in the aperture (8-5), adjusting security protection bolt (7-2) makes it press closer clip (8-1) side, when the support pressurized promotes distortion, the post leg promotes drag device and slides inwards, because rubbing action makes and increases the resistance wedge and be pushed and erect, increased the normal pressure with back timber simultaneously, make support realize increasing resistance at horizontal direction.
The utility model only need be pounded out horse wedge (3-4), and pressure roller horse (3-3) and compression roller (3-2) are taken out, and pilum just can be opened as loose-leaf, makes that support is convenient to install and use, demolition, recovery transportation be very convenient.This support can be avoided roadway surrounding rock stress peak owing to adopt novel unique texture, has solved the geological conditions complexity effectively, and the roof and floor fragmentation is loose, the supporting problem in weak coal petrography tunnel.
