Embodiment Construction

[0020] The present invention is described in detail as follows in conjunction with accompanying drawing:

[0021] The specific implementation process:

[0022] image 3 with Figure 4 In, connect cylinder block (17) and end cover (14);

[0023] Image 6 with Figure 7 In, the piston (8) and the guide rod (1) are installed as a whole;

[0024] The piston (8) and the guide rod (1) are installed as a whole, installed in the structure of the first step, and then the outer surface of the end cover (14) and the guide rod (1) are contacted to install the sealing material packing (24) , secondly, gasket (31) is installed outside packing (24), at last, gland (21) is installed outside gasket (31), screw on and get final product.

[0025] Install the base (20) on the end cover (14) of the cylinder body, so that the hydraulic cylinder (9) is installed; use the liquid injection pipe (3) to connect the hydraulic cylinder (9) and the safety three-way valve (5) , so that a complete cir...

Abstract

The invention relates to a hydraulic coupling anchor bolt which structurally comprises an anchor end, an anchor bolt body, a piston, a hydraulic cylinder, a tray, a nut, a liquid injection pipe and other parts. According to the hydraulic coupling anchor bolt and a monitoring system thereof, an anchor bolt which is used for supporting an underground roadway or actively reinforcing a slope, a tunnel and a dam body in a project technology is particularly applicable to the supporting of the roadway with a more complete top plate. According to the hydraulic coupling anchor bolt, the pressure of the anchor bolt can be relieved through a hydraulic device, so that the anchor bolt is not sheared, damaged and ineffective due to large pulling force; and meanwhile, the purpose of reinforcing the liquid injection of the hydraulic cylinder of the anchor bolt can be achieved, and finally the supporting and flexible supporting are enhanced. The tail part of the hydraulic coupling anchor bolt is provided with the hydraulic device, so that the deformation and the stress of the wall rock of the roadway are automatically adjusted.

Description

technical field [0001] The invention relates to a hydraulically coupled bolt, which is suitable for supporting the surrounding rock of roadways. Background technique [0002] At present, in the mine roadway support, ordinary mine bolts are only simple rigid materials, which cannot fully realize continuous support and flexible support for the roadway, that is, under the influence of mining, due to the broken rotation of the basic roof and the support With the occurrence of pressure concentration and other phenomena, the surrounding rock of the mining roadway has large deformation characteristics. Even under the action of ordinary bolt support, this large deformation characteristic is often irresistible, that is, the support can only play a role in the deformation process of the surrounding rock. A certain slowing and controlling effect can reduce the deformation of the surrounding rock to a certain extent, but it cannot completely prevent the occurrence of this large deformat...
