Wherein,
1, live post, 11, backing plate, 12, controller, 13, display, the 14, first connecting hole, 2, hydraulic oil container, 21, assembly cavity, 22, pressure transducer, 23, unloader, the 24, second connecting hole, 3, anchor bar body, 4, nut, 5, country rock.
Detailed description of the invention
Embodiment one:
As it is shown in figure 1, the present embodiment provides a kind of hydraulic pressure pressure-relieving achor bar.The end of anchor bar body 3 stretches in country rock 5 and is connected through Anchor Agent is fixing with country rock 5, the other end assembly connection of anchor bar body 3 has nut 4, one end of post 1 alive is fixedly connected with backing plate 11, post 1 of living is connected together through backing plate 11 and nut 4, hydraulic oil container 2 offers assembly cavity 21, the distal opening of assembly cavity 21, post 1 of living may be inserted into the post 1 alive of realization in assembly cavity 21 and hydraulic oil container 2 is flexibly connected, living post 1 can be for linear motion relative to assembly cavity 21, hydraulic oil container 2 is provided with unloader 23, unloader 23 in the present embodiment is electromagnetic valve, controller 12 is with solenoid signal even.Offering the first connecting hole 14 on post 1 alive, hydraulic oil container 2 offers the second connecting hole 24, anchor bar body 3 is through the first connecting hole 14 and the second connecting hole 24, and anchor bar body 3 is flexibly connected with the second connecting hole 24.Being provided with pressure transducer 22 in hydraulic oil container 2, post 1 of living is provided with controller 12 and display 13, controller 12 is connected with pressure transducer 22, display 13 signal respectively.
Hydraulic pressure pressure-relieving achor bar work process in the present embodiment is as follows: the end of anchor bar body 3 is fixed with country rock 5 after being connected, the size of the pretightning force of anchor pole is monitored by pressure transducer 22, and send data in display 13 by controller 12, so that anchor pole reaches certain pretightning force when mounted, anchor pole is made to play the effect of active support.When country rock 5 deforms, anchor bar body 3 stress is drawn, post 1 of living moves through the direction to hydraulic oil container 2 that coordinates of assembly cavity 21, hydraulic oil in hydraulic oil container 2 is compressed, the pressure that pressure transducer 22 monitors increases, and opens electromagnetic valve by controller 12, makes a hydraulic oil flow process part in hydraulic oil container 2, regulate according to country rock 5 stress and allow pressure value, reach the purpose of deformation controlling for rock surrounding gateways.When the pressure of the hydraulic oil in hydraulic oil container 2 reduces, closed electromagnetic valve, along with the continuation of country rock 5 deforms, the pressure of the hydraulic oil in hydraulic oil container 2 gradually rises again, and then electromagnetic valve is opened again, so goes round and begins again.
Embodiment two:
The present embodiment and embodiment one are different in that, the unloader 23 in the present embodiment be relief valve, control the hydraulic pressure oil-out in hydraulic oil container 2 by arranging the threshold values of relief valve, so change pressure-relieving achor bar allow pressure value.
Certainly; described above is not to restriction of the present utility model; this utility model is also not limited to the example above, the change made in essential scope of the present utility model of those skilled in the art, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
