The native bin membrane backside that
soil pressure meter is mounted in shield machine is used to measure a kind of apparatus of native bin soil pressure.Shield machine can be in underground smooth digging, and the pressure of native bin controlled well is key point, so the soil pressure counter device is an imperative equipment on the shield machine.Be quick, safe digging, the operator will observe soil pressure meter pressure in good time, if the soil pressure meter damages or breaks down, then needs to change in time or maintenance soil pressure meter.Soil pressure meter of the prior art more changing device mainly contains spherical rotary and door-plate cut-off type etc.In the soil pressure timing that change to damage, the soil pressure meter more the pull of changing device through spherical surface body rotation or door-plate with the soil layer retaining outside machine, be not very convenient during replacing
Summary of the invention
in order to address the above problem, and the object of the present invention is to provide the more convenient shield structure of a kind of replacing that makes the soil pressure meter with soil pressure meter changing device more.
in order to reach above purpose, the technical scheme that the present invention adopts is: a kind of shield structure comprises the mount pad of hollow and the hollow ram that can in the cavity of said mount pad, move forward and backward with soil pressure meter changing device more; The ball valve that said mount pad comprises the joint that is welded on the native bin dividing plate, is fixedly connected with said joint, and the fixed part that an end is connected on the said ball valve, the other end has flange face; The cavity front end of said push rod forms the mounting groove that can fixedly mount the soil pressure meter, and the tail end of said push rod outwards forms a flange face and makes and can match fixing through two flange faces between said push rod and the said fixed part.
preferably, said ball valve is a whole-through diameter ball valve.
preferably, the mounting groove of said push rod front end is arranged to the diminishing taper of bore from outside to inside, and between said mounting groove and the soil pressure meter through being threaded.Mounting groove is arranged to taper, is in order to improve the sealing performance of soil pressure meter installed surface.
preferably are fixedly connected through bolt between the tail end flange face of said push rod and the flange face of fixed part.
preferably also are provided with screw rod parallel with push rod, that be used to lead between said push rod and the fixed part.
preferably, said soil pressure meter more changing device also is provided with a circle sealing ring on fixed part and inwall that said push rod contacts.
Owing to adopted technique scheme, the present invention compared with prior art has following advantage:
shield structure of the present invention with the soil pressure meter more changing device utilize logical the closing of ball valve control mount pad internal cavity, utilize the push-and-pull action of push rod, can take out and install the soil pressure meter easily, simple in structure, easy to operate.
