Description
Technical field
The utility model is related to duct piece assembling machine provisioned on Suporting structure drivings, particularly relate to a kind of for tunnel digging
Into the soil pressure case mounting structure of machine.
Background technology
Balancing earth-pressure shielding machine is to ensure tunnel upper earth's surface by ensureing the soil pressure in native storehouse in a certain range
Sedimentation or protuberance, the soil pressure in native storehouse is measured for ensureing that construction safety has key effect by soil pressure case.It is existing
Some balancing earth-pressure shielding machines monitor support pressure by installing multiple soil pressure cases in front baffle, are used for tunnel piercing
The support pressure sensor of machine, medium is come into contact in a large area generally by detection faces, be suitable for close and occasion, it is especially sticky or
Pasty media and strongly corrosion liquid, or the measurement rich in particulate species medium, simple in structure, with good stability and repetition
Property, the support pressure for being widely used to rock tunnel(ling) machine measures.But traditional mounting means be by sensor be mounted on every
On the inside of plate, farther out with soil body distance, clay can cause channel blockage to diaphragm after entering, and cause the sensitivity decrease measured, if will
When sensor detection faces distance Tu Cang is closer, sensitivity is higher, but detection faces are easy to wear, is often subject to the shock of dregs and damages
Bad, service life is relatively low.
Invention content
The utility model proposes a kind of soil pressure case mounting structures for rock tunnel(ling) machine, improve pressure sensor
Measurement accuracy and service life are easily installed the replacement with vulnerable part.
What the technical solution of the utility model was realized in：
A kind of soil pressure case mounting structure for rock tunnel(ling) machine, including shield machine shield body partition board, shield machine shield body
Pedestal is provided in partition board, pedestal is connected with connecting plate, and connecting plate is connected with soil pressure case, is arranged between pedestal and connecting plate
There is sheet rubber, power transmission medium is provided between sheet rubber and soil pressure case.
The sheet rubber is spherical surface sheet rubber, the dynamometry face of the protrusion direction of spherical surface sheet rubber backwards to soil pressure case.
The power transmission medium is 1# lithium saponifies.
It is provided with sealing ring between the connecting plate and soil pressure case.
The connecting plate and pedestal are bolted.
The utility model increases the thin rubber sheet of a spherical surface, sheet rubber and measurement in the measuring surface front end of soil pressure case
Stuffing pressure transfer medium between face, soil pressure act on the curved surface of rubber sheet, are then transmitted by pressure transmission medium
To soil pressure case, the detection of pressure is realized；The utility model can avoid soil pressure case and directly be in contact with the soil in native storehouse,
The measuring surface of sensor is prevented to be often subject to the shock of dregs and damage, while avoiding clay will be before sensor measurement face
Channel blockage influences measurement accuracy；The spherical surface sheet rubber of the utility model can increase detection faces compared to plane, improve detection
Sensitivity；The connecting plate and pedestal of the utility model be bolted, it can be achieved that curved surface sheet rubber and power transfer medium more
It changes, under the premise of meeting measurement accuracy, effectively improves the service life of soil pressure case.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not under the premise of making the creative labor
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, the utility model embodiment provides a kind of soil pressure case installation knot for rock tunnel(ling) machine
Structure, including shield machine shield body partition board 7 are provided with pedestal 4 in shield machine shield body partition board 7, and pedestal 4 is connected with connecting plate 3, connecting plate
3 are connected with soil pressure case 1, and sheet rubber 5 is provided between pedestal 4 and connecting plate 3, is set between sheet rubber 5 and soil pressure case 1
It is equipped with power transmission medium 6.
The sheet rubber 5 is spherical surface sheet rubber, the dynamometry face of the protrusion direction of spherical surface sheet rubber backwards to soil pressure case 1.
The power transmission medium 6 is 1# lithium saponifies.
Sealing ring 2 is provided between the connecting plate 3 and soil pressure case 1.
The connecting plate 3 and pedestal 4 are bolted.
The soil pressure case of the utility model measures the pressure in native storehouse by sheet rubber, solves in traditional measurement method
Force-detecting position and the soil body distance farther out the problem of, avoid and cause channel blockage after clay enters, the problem of measurement sensitivity reduces；
The utility model bears support pressure by sheet rubber, and the dynamometry face of soil pressure case is protected not to be damaged, and extends its service life.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
