Abstract
The utility model discloses an automatic leveling steering device for a shield trackless trailer in a circular tunnel. The automatic leveling steering device comprises leveling steering oil cylinders (6) arranged on wheels; the leveling steering oil cylinders (6) are provided with displacement sensors (5) and connected with a hydraulic source (4) through pipelines; hydraulic control valves (3) are arranged on the pipelines between the leveling steering oil cylinders (6) and the hydraulic source (4) and connected with a PLC control unit (2); the PLC control unit (2) is connected with a horizontal detector (1) arranged on the shield trackless trailer. According to the automatic leveling steering device, the defects that because the trailer of a shield machine walks along the inner wall of the tunnel through the rubber wheels, the trailer will tilt sideways when moving at a corner or when the wheels tilt, and the wheels of the trailer will be abraded due to the fact that the revolving directions of the wheels are inconsistent are overcome. Besides, the problems of leveling and direction adjusting of the trackless trailer of the shielding machine in the circular tunnel are solved, and meanwhile automatic control over leveling of the trailer is achieved.
Description
Technical field
The utility model relates to the automatic Pilot field of the walking leveling of a kind of trailer and its free-wheel car, is specially a kind of and is applied in circular tunnel the automatic leveling steering hardware of free-wheel car in shield structure trailer and other tunnels.
Background technology
Along with social development, especially capital construction is constantly perfect, and earth-shaking variation has occurred people's living standard, and in the process of capital construction, especially, in tunnel construction, shield machine has played irreplaceable effect.
In shield-tunneling construction process, as the shield structure trackless trailer wheel of the organic component of shield machine to walking along circular section of jurisdiction inwall, inevitably there will be trailer to roll phenomenon, so just need to turn to the trailer platform level of adjusting by trailer wheel, with avoid to the framing members such as trailer, wheel bring needn't otherwise damage, if but the tuning of two wheels was inconsistent in adjusting, will cause the wearing and tearing of trailer rubber tire.
Therefore, provide a kind of and can guarantee that shield structure trackless trailer is along realizing automatic leveling in the inwall walking process of section of jurisdiction, and wheel turning to unanimously, prevent the setting device that rolls in the process of walking, has been a good problem to study.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides consistent that shield structure trackless trailer automatic leveling device in a kind of circular tunnel both guaranteed that in trailer walking process, wheel turns to, and can realize again trailer automatic leveling in the process of walking.
The purpose of this utility model is achieved in that
Shield structure trackless trailer automatic leveling steering hardware in circular tunnel, it is characterized in that: comprise the leveling steering cylinder 6 being arranged on wheel, on leveling steering cylinder 6, be provided with displacement pickup 5, leveling steering cylinder 6 is connected with hydraulic power source 4 by pipeline simultaneously, on pipeline between leveling steering cylinder 6 and hydraulic power source 4, be provided with fluid control valve 3, fluid control valve 3 is connected with PLC control unit 2, and PLC control unit 2 is connected with the horizon detector 1 being arranged on trackless trailer;
Described displacement pickup 5 is connected with PLC control unit 2;
Described fluid control valve 3 comprises balance cock 3-1, flow regulating valve 3-2 and solenoid directional control valve 3-3, and balance cock 3-1, flow regulating valve 3-2 and solenoid directional control valve 3-3 be connected with PLC control unit 2 simultaneously, and controlled by it;
Described leveling steering cylinder 6 comprises the near front wheel oil cylinder 6-1 being arranged on the near front wheel, is arranged on the off front wheel oil cylinder 6-2 on off front wheel, is arranged on the left rear wheel oil cylinder 6-3 on left rear wheel and is arranged on the off hind wheel oil cylinder 6-4 on off hind wheel.
positive beneficial effect:the utility model device has overcome because the trailer of shield machine adopts rubber tire walks along tunnel inner wall, runs into bend or wheel and occurs tilting, and trailer just there will be inclination phenomenon, and turning to of wheel inconsistently also can be caused the wearing and tearing that trailer wheels is right.The utility model has solved the problem of the walking leveling tuning of shield machine trackless trailer in circular tunnel, has realized again the automation of trailer leveling and has controlled.
Accompanying drawing explanation
