Abstract
The utility model discloses a kind of anterior shield soil pressure case and measure frock, belong to shield machine frock field.It comprises pneumatic triplet, stop valve, tensimeter, ring flange, described ring flange is fixed on shield body front end face, described ring flange arranges a shoulder hole, and the large nose end of shoulder hole is near described shield body front end face, arranges a soil pressure case in the macropore of this shoulder hole.After pressurized air carries out filtration and pressure setting by pneumatic triplet, soil pressure case surface is flowed to by flange disk hole, if sensor flexibly effectively, force value can be shown by the sensor film viewing screen in pulpit, whether contrast is consistent with the gas pressure value flowed into, and can judge the validity of this soil pressure case.Therefore, be in off working state at shield machine, especially the debug phase before shield machine dispatches from the factory, the support pressure that this frock can be utilized to simulate when excavating detects soil pressure case, and this tool structure is simple, easy and simple to handle, practical.
Description
Technical field
The utility model relates to shield machine and measures frock field, particularly relates to a kind of measurement frock of shield machine anterior shield soil pressure case.
Background technology
Shield machine is mainly used in constructing tunnel, the operating mode of shield-tunneling construction is general comparatively severe, soil pressure case is arranged on anterior shield Tu Cang side, the force value of Tu Cang during for measuring driving, and feed back to PLC system or operating personnel, as the foundation adjusted the worm conveyor amount of being unearthed, reach the object controlling support pressure, ensure the earth pressure balance of shield machine, realize normally tunneling.Its being called " eyes of shield machine " by image, act on great.But when debugging before shield machine dispatches from the factory, because soil pressure case is installed to anterior shield Tu Cang rear flank, sensor surface is that exposure is aerial, not easily forms measurable pressure, detection difficult on its surface.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of anterior shield soil pressure case and measures frock, solves the problem of soil pressure case detection difficult.
The technical scheme that the utility model adopts is: a kind of anterior shield soil pressure case measures frock, comprise pneumatic triplet, stop valve, tensimeter, ring flange, described ring flange is fixed on shield body front end face, described ring flange arranges a shoulder hole, and the large nose end of shoulder hole, near described shield body front end face, arranges a soil pressure case in the macropore of this shoulder hole.
Anterior shield soil pressure case described in the utility model is measured in frock, and the end that described shield body front end face is close to by described ring flange arranges an annular groove, arranges grommet type seals in this groove.
Anterior shield soil pressure case described in the utility model is measured in frock, and described pneumatic triplet is connected by pipeline with tensimeter, and the gas outlet of this pipeline is just to the aperture of described shoulder hole.
Anterior shield soil pressure case described in the utility model is measured in frock, and the connecting tube between described pneumatic triplet and tensimeter is connected with second pipe, and described stop valve is arranged on this second pipe.
Anterior shield soil pressure case described in the utility model is measured in frock, and ring flange is fixed on shield body front end face by four socket head cap screws.The beneficial effects of the utility model are:
The beneficial effects of the utility model are:
When shield machine is in off working state, the especially debug phase before shield machine dispatches from the factory, the support pressure utilizing this frock to simulate when excavating detects soil pressure case, and this tool structure is simple, easy and simple to handle, practical.
Accompanying drawing explanation
Fig. 1 is that anterior shield soil pressure case described in the utility model measures the simplified structural representation of frock;
Fig. 2 is the sectional view of ring flange described in the utility model.
The pneumatic triplet of 1-; 2-stop valve; 3-ring flange; 4-grommet type seals; 5-soil pressure case; 6-socket head cap screw; 7-tensimeter.
Embodiment
Be described further below with reference to accompanying drawing 1 and accompanying drawing 2 pairs of the utility model, but protection domain of the present utility model should do not limited with this.
Contrast accompanying drawing 1 and accompanying drawing 2:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, a kind of anterior shield soil pressure case measures frock, comprises pneumatic triplet 1, stop valve 2, tensimeter 7, ring flange 3; Described ring flange 3 is fixed on shield body front end face 10, and described ring flange 3 arranges a shoulder hole, and macropore 301 end of shoulder hole is near described shield body front end face 10, arranges a soil pressure case 5 in the macropore 301 of this shoulder hole.
Concrete, the end that described shield body front end face 10 is close to by ring flange 3 arranges an annular groove 303, arranges grommet type seals 4 in this groove 303; So just, the space of relative closure can be formed between macropore 301 and shield body front end face 10, so can utilize soil pressure during pressurized air simulation shield machine driving on soil pressure case 5 surface; Ring flange is fixed on shield body front end face 10 by four socket head cap screws 6.
Described pneumatic triplet 1 is connected by pipeline with tensimeter 7, and the gas outlet of this pipeline is just to the aperture 302 of described shoulder hole; Connecting tube between described pneumatic triplet 1 and tensimeter 7 is connected with second pipe, and described stop valve 2 is arranged on this second pipe.
Principle of work:
After pressurized air carries out filtration and pressure setting by pneumatic triplet 1, the surface of soil pressure case 5 is flowed to behind aperture 302 hole of ring flange 3, if now sensor flexibly effectively, force value can be shown by the sensor film viewing screen in pulpit, whether contrast is consistent with the gas pressure value flowed into, and can judge the validity of this soil pressure case 5.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this instructions, these terms just for convenience of description, do not form any restriction to the utility model.
