Solidifying soil shunts uneven in hopper, causes tunnel double-lining trolley or so unbalance stress, produces bias, stablizes for trolley structure
Have a negative impact.
The content of the invention
The deformation of tunnel double-lining trolley is mainly manifested in torsional deformation, and two lining trolley liftings are by the oil cylinder liter installed on trolley
Drop is controlled, and oil cylinder is fixed on longeron, and the torsional deformation of trolley causes longeron to distort, and then causes oil cylinder axial force cannot
Act on vertically on longeron, trolley has the risk that collapses.Tunnel double-lining trolley torsional deformation can make trolley termination not same at the same time
On one section, when causing the next lining of plate two construction, trolley cannot uniformly be overlapped with tunnel double-lining termination, and short abutment wall lap-joint is wrong
Platform, in addition inverted arch, two lining construction joints cannot " double slit unification ", tunnel generation differential settlement when cause Tunnel Second Lining to be drawn
Split, influence the overall stability of concrete structure.
The content of the invention
The purpose of the utility model is to overcome the defects of above-mentioned technology, there is provided a kind of tunnel double-lining trolley deformation monitoring dress
Put.State after the device can position tunnel double-lining ride car is monitored, and makes tunnel double-lining trolley or so uniform force,
Avoid producing bias and the risk that collapses.Tunnel double-lining trolley is overcome on same section, when next plate two is served as a contrast and constructed, trolley energy
Uniformly overlapped with tunnel double-lining termination, short abutment wall lap-joint not faulting of slab ends, it is ensured that inverted arch, two lining construction joints can " double slit unification ", guarantor
Demonstrate,prove trolley structure stability.
The purpose of this utility model is achieved through the following technical solutions：A kind of tunnel double-lining trolley deformation monitoring device, it
Including base, cylinder, cord, spring, dial, clip, screw rod and nut.
The tunnel double-lining trolley deformation monitoring device：Disc base 1 with centre bore and the installation of cylinder 5 are connected in
Together, 4 uniformly distributed holes are equipped with the disc base of centre bore periphery；The barrel of cylinder is equipped with straight-cut plane, indulges
Longitudinal round recessed is formed between preceding barrel and rear cylindrical wall to cutting plane；Spring is mounted in cylinder into longitudinal round recessed；
For hoop sleeve on cylinder outer wall, clip both ends are respectively equipped with hole, dial are housed between clip both ends, screw rod is inserted into dial
In the hole at clip both ends, on screw rod, dial controls between the both ends of clip nut；The left end of spring and first thin
One end of rope connects, and the other end of the first cord is stretched out outside the hole of disc base, is fixed on cylindrical base connection
Crossbeam（Or longeron）On；Second cord be coiled in dial it is cylindrical on groove in, the left end of the second cord and the right end of spring
Link together, the right end of the second cord stretches out outside cylinder the mould being mounted in mounted in tunnel side wall template with the short abutment wall intersection of inverted arch
On plate.
Second cord, the right end of the second cord, which is stretched out outside cylinder, is mounted in tunnel double-lining trolley arch wall template and termination
In template at template interface.
When trolley monitoring position fixed position relative is subjected to displacement, spring produces dilatation, and cord drives dial,
Dial rotation, the deflection of trolley can be determined according to numeral on dial.
For more existing monitoring technology, the utility model has the advantage of：
1. cost is low：It is low compared to optical gauge tunnel double-lining trolley deformation monitoring device cost, engineering can be reduced and applied
Work measuring instrument input cost, while reduce survey crew's input；
2. measurement data accuracy：Tunnel double-lining trolley deformation monitoring device any angle can be installed on trolley, more
The deflection that accurately trolley produces in measurement concreting process.
3. ambient adaptability is strong：The tunnel double-lining trolley deformation monitoring device, it is relatively hidden to be applicable to measurement trolley
The deflection at position.Optical gauge is disturbed by tunnel double-lining trolley labyrinth, and measuring point limitation is larger, and monitors
Device is stronger with respect to the structure applicability of tunnel double-lining trolley complexity, is influenced from tunnel driving vehicle.
It is 4. easy to operate：The tunnel double-lining trolley deformation monitoring device, the steering of dial can directly react trolley hair
The direction for the shape that changes, and deformation numerical value can be directly read, result is read from the such environmental effects such as temperature, vibrations.Apply at scene
Work operating personnel can voluntarily observed result, and need to add according to observed result control concreting speed, timely processing trolley
Solid position.
