Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The utility model aims at providing a supporting construction for coal mine tunnel to solve the problem that above-mentioned prior art exists, adapt to the protection in not co-altitude's tunnel, and improve stability.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1: the embodiment provides a supporting structure 100 for a coal mine tunnel, which comprises a base plate 1 positioned at the bottom end, two side plates 2 respectively positioned at two sides, two supporting rods with the middle parts rotatably connected through a rotating shaft 13 and two supporting units positioned at two sides of the rotating shaft 13; the two support rods are respectively a first support rod 3 and a second support rod 4.
The two support rods are positioned between the two side plates 2, the rotating shaft 13 is horizontal, and the axial direction of the rotating shaft 13 is parallel to the length direction of the side plates 2; the bottom of every bracing piece all sets firmly pulley 10, and the top surface of base plate 1 corresponds pulley 10 and is provided with the spout, and pulley 10 and the spout sliding fit that corresponds can adjust the height on two bracing piece tops through adjusting the angle between two bracing pieces to adapt to the not tunnel of co-altitude. The top of every bracing piece all sets firmly connecting block 11, all sets firmly clutch blocks 12 on the top surface of every connecting block 11. The friction block 12 is arc-shaped, and the friction block 12 is an elastic rubber friction block 12. When strutting, the clutch blocks 12 of connecting block 11 top will contact with the wall in advance to increase contact friction through clutch blocks 12, let the stable conflict to the wall of deformation power that pressurized clutch blocks 12 took place simultaneously, improved support stability.
Every supporting element all includes two along vertical direction interval distribution, and set firmly jack 5 on the inner wall of curb plate 2, the ejector pin of jack 5 can the level stretch out and draw back, every ejector pin all is connected with a horizontal connecting rod 6, the other end of every horizontal connecting rod 6 rotates and is connected with a load and holds in the palm, two loads hold in the palm and hold in the palm 8 and second load and hold in the palm 9 for first load respectively, first load in same supporting element holds in the palm and is connected with vertical connecting rod 7 between 8 and the second load holds in the palm 9, and first load holds in the palm 8 and second load and holds in the palm 9 and all rotate with vertical connecting rod 7 and be connected. The back that first load held in the palm 8 and second load held in the palm 9 has set firmly the connecting seat respectively, and horizontal connecting rod 6 and vertical connecting rod 7 rotate with the connecting seat respectively and are connected. It should be noted that, after the first support rod 3 and the second support rod 4 are connected by the rotating shaft 13, the first support rod 3 and the second support rod 4 are not actually located in the same vertical horizontal plane, which causes the two load bearing supports not to actually correspond to each other completely, and in order to avoid the problem, the middle parts of the two support rods can be half-cut and then rotationally connected, so as to ensure that the axes of the two support rods are completely located in the same vertical plane; the position deviation of the two first force bearing supports 8 and the second force bearing support 9 can also be overcome by properly adjusting the connecting position of the vertical connecting rod 7, for example, the vertical connecting rod 7 is positioned between the connecting seat of the first force bearing support 8 and the connecting seat of the second force bearing support 9.
