Abstract
The utility model belongs to the technical field of a supporting device for a coal mine, particularly relates to a supporting device for pressure transfer of an underground roadway, and mainly solves the problems of high probability of section shrinkage, side fall, roof fall and floor heave, need of newly enlarging a rib, undercutting, performing top brushing and trimming the roadway, high cost and influence on production procedure due to mine pressure in coal mining. The technical scheme provided by the utility model is that: the supporting device for the pressure transfer of the underground roadway comprises the roadway, a reinforcing mesh, iron wire meshes, top anchor ropes, side anchor ropes, bottom anchor ropes, anchor rods and rigid anchor rope beams, wherein the top anchor ropes are arranged on the top of the roadway at an angle of between 35 degrees and 45 degrees; the bottom anchor ropes 10 are arranged at the bottom of the roadway at an angle of between 35 degrees and 45 degrees; the side anchor ropes are arranged on two sides of the roadway at an angle of between 65 degrees and 75 degrees; and the rigid anchor rope beams are arranged on the top and at the bottom of the roadway 1. Through the supporting device, the supporting time of the roadway is effectively prolonged, the reforming frequency of the roadway is reduced, the production cost is reduced, and the production efficiency is increased.
Description
Technical field
The utility model belongs to coal mine suspension device technical field, is specifically related to a kind of underworkings pressure transfer suspension device.
Background technology
In process of coal mining, various tunnels all exist the ore deposit to press the unsafe factor that is brought, therefore people often adopt anchor pole, anchor cable, devices such as anchor canopy combined supporting come the supporting tunnel, but people are usually with the vertical top of squeezing into the tunnel with anchor cable of anchor pole, the anchor cable and the weight at top, tunnel are all vertical like this is pressed in above the tunnel, then passing on two helps and the bottom, time has been grown, press in the ore deposit that produces will be to same direction vertical depression, what this moment, anchor cable play a part just suspends pressure, and this compound beam of bolt support also can be damaged under the situation of overburden, and the tunnel section atrophy occurs even rolls group's roof fall pucking under pressurized.In order to continue exploitation, people have to split group again, undercut, caunch, repair the tunnel, have both increased the input of cost of production, have also delayed the time, have influenced the progress of producing.
Summary of the invention
The utility model is primarily aimed at coal mining chats pressure and makes the easy section atrophy in tunnel, rolls group's roof fall pucking and split group again, undercuts, caunches, repairs the tunnel, the cost height, influence the problem of manufacturing schedule, and the underworkings pressure transfer suspension device that a kind of roadway support time is long, avoid overlapping investment is provided.
The utility model is to address the above problem the technical scheme of taking to be:
A kind of underworkings pressure transfer suspension device, comprise the tunnel, be arranged on wire gauze, top anchor cable, group anchor cable, end anchor cable and anchor pole that the steel mesh reinforcement and two at top, tunnel is helped, wherein: also comprise rigidity anchor cable beam, described top anchor cable is 35～45 ° of tops that are arranged on the tunnel, end anchor cable 10 is 35～45 ° of bottoms that are arranged on the tunnel, and group's anchor cable is 65～75 ° and is arranged on two of tunnel and helps; Wherein said top anchor cable, end anchor cable and group's anchor cable are fixed on the tunnel by lockset, and are provided with the steel pad between lockset and tunnel; Described anchor pole is arranged on the top and two in tunnel and helps; Described rigidity anchor cable beam is arranged on the top and the bottom in tunnel 1.
Described steel pad is wedge-type three angle steel pads.
The utility model adopts technique scheme, is applicable to various tunnels, as trapezoidal, trapezoid, arch, circle etc.Top anchor cable and group's anchor cable are arranged on the tunnel with certain angle, according to resolution of forces, quite a few weight of top will be transferred to two and help, under the cooperation of group's anchor cable, alleviated top and two and helped pressure the tunnel, alleviated the load in tunnel, end anchor cable has effectively been controlled by roof pressure and has been passed on the pucking that causes to the bottom, the below of each anchor cable all adopts lockset to fix simultaneously, and wedge-type three angle steel pads are set between tunnel and lockset, guarantees the supporting angle and the intensity of anchor cable, effectively prolonged the support time in tunnel, reduce the reformation number of times in tunnel, reduced cost of production, improved the efficient of producing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of underworkings pressure transfer suspension device, comprise tunnel 1, be arranged on wire gauze 3, top anchor cable 4, group anchor cable 5, end anchor cable 10 and anchor pole 6 that the steel mesh reinforcement 2 and two at 1 top, tunnel is helped, wherein: also comprise rigidity anchor cable beam 9, described top anchor cable 4 is 35～45 ° of tops that are arranged on tunnel 1, end anchor cable 10 is 35～45 ° of bottoms that are arranged on tunnel 1, and group's anchor cable 5 is 65～75 ° and is arranged on two of tunnel 1 and helps; Wherein said top anchor cable 4 and end anchor cable 10 are fixed on the tunnel 1 by two locksets, and group's anchor cable 5 is fixed on the tunnel 1 by a lockset 7, and is provided with wedge-type three angle steel pads 8 between lockset 7 and tunnel 1; Described anchor pole 6 is arranged on the top and two in tunnel 1 and helps; Described rigidity anchor cable beam 9 is arranged on the top and the bottom in tunnel 1.
