Description
Technical field
The utility model provides a kind of shield machine automatic deviation correction anti-derail unit, belongs to shield-tunneling construction field.
Background technique
The wheel that shield machine uses currently on the market uses traditional form, and wheel acts on guide rail, and shield machine is
Advance according to desired trajectory.Shield machine often occurs in the construction process and deviates desired trajectory, especially in the advance of long range
In the process, once shield machine deviates desired trajectory, it is necessary to implement and rectify a deviation to shield machine.Transmission is using manual deviation rectification side
Formula prevents from derailing, by its direction of advance of manual control, to automatic control currently without good automatic control mode.But using manually
Control, safety and precision all there is a problem of very big.
Summary of the invention
The utility model solves above-mentioned technical problem and provides a kind of shield machine automatic deviation correction anti-derail unit, the skill solved
Art problem is that shield machine trolley is made to remain that walking in orbit, prevents accidental cause from de-orbiting when dragging forward, is improved
Working efficiency.
The utility model solves the technical solution that technical problem uses:
A kind of shield machine automatic deviation correction anti-derail unit, it includes the multiple left directive wheels being arranged in left rail, left
Setting left side cylinder bracket on directive wheel, left side cylinder bracket is equipped with left guiding oil cylinder, corresponding to be arranged in right rail
Multiple right directive wheels, setting right side cylinder bracket, right side cylinder bracket are equipped with right guiding oil cylinder on right directive wheel, and described entangles
Inclined anti-derail unit further includes laser alignment telescope, identical journey of the laser alignment telescope for the detection guiding wheel track on the basis of track
Degree, the left guiding oil cylinder and right side guiding oil cylinder are controlled by PLC control system, and PLC control system includes pump, are connected on pump
Ratio solenoid directional control valve, ratio solenoid directional control valve is separately connected the upper and lower cavities of left guiding oil cylinder and right guiding oil cylinder, described
A mouthfuls of overflow valves and B mouthfuls of overflow valves are respectively equipped between ratio solenoid directional control valve and left guiding oil cylinder and right side guiding oil cylinder.
Left side guiding oil cylinder and right side guiding oil cylinder and its bracket on above-mentioned left and right rail are symmetrical arranged, having the same
Component.
The utility model has the beneficial effects that
1, the left and right directive wheel in No.1 trolley of the utility model respectively adds a guiding oil cylinder, passes through laser guide
Instrument incudes the degree of agreement of left and right directive wheel and track, and issues a signal to PLC, controls proportional reversing valve by PLC, makes to pump defeated
Hydraulic oil out reaches the rod chamber or rodless cavity of left and right guiding oil cylinder, travels in orbit to be precisely controlled directive wheel, this
Shield machine automatic deviation correction anti-derail unit, greatly improves work efficiency, and improves the accuracy and safety of shield machine；
2, the application can monitor the degree of agreement of directive wheel and track in real time, and the tiny deviation of real time correction prevents vehicle
Wheel is detached from track, is effectively improved working efficiency, is increased the safety coefficient of shield machine, improves the market competition of product
Power.
Detailed description of the invention
It is illustrated below in conjunction with attached drawing with embodiment
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram of PLC of the present invention.
Specific embodiment
Referring to attached drawing 1-2, a kind of shield machine automatic deviation correction anti-derail unit, it include be arranged in it is more in left rail 5

Multiple right directive wheels 9 are set in right rail 6, and setting right side cylinder bracket 7, right side cylinder bracket are equipped on right directive wheel
Right guiding oil cylinder 8, the correction anti-derail unit further include laser alignment telescope 2, and laser alignment telescope is used on the basis of track
The degree of agreement of detection guiding wheel track, the left guiding oil cylinder and right side guiding oil cylinder are controlled by PLC control system, PLC
Control system includes pump 10, connects ratio solenoid directional control valve 11 on pump, ratio solenoid directional control valve be separately connected left guiding oil cylinder and
The upper and lower cavities of right guiding oil cylinder are set respectively between the ratio solenoid directional control valve and left guiding oil cylinder and right side guiding oil cylinder
There are A mouthfuls of overflow valves 12 and B mouthfuls of overflow valves 13.
Preferably, the left side guiding oil cylinder on the left and right rail and right side guiding oil cylinder and its bracket are symmetrical arranged, tool
There is identical component.
The protection scope of the utility model is not limited to the above embodiments, it is clear that those skilled in the art can be right
The utility model carries out various changes and deformation without departing from the scope of the utility model and spirit.If these changes and deformation
Belong in the range of the claims of the present invention and its equivalent technology, then the intention of the utility model also include these change and
Including deformation.
