The packing device is reasonable in structural design, has a wide applicable scope, and can perform modular disassembly combination of the frame according to packing load, the longitudinal and transverse rigidity of the frame is high, parallel operation and running synchronization can be simultaneously realized, and the morphological stability and the running flexibility of packing components are guaranteed.
Description
Technical field
The invention belongs to integral bridge replacement technique equipment, carry out the device of packing that integral bridge loads transportation when being specifically related to a kind of integral bridge displacement.
Background technology
Bridge is affected by the multiple factors of traffic loading and natural cause, and along with the continuity of service time, structure can produce and continue deterioratedly, so Bridge Reconstruction or reconstruction are important topics in bridge life later stage.But owing to being subject to the restriction in traffic and place, traditional old bridge reforming mode need to carry out the original place to original bridge to be removed and rebuilds, and often takes during construction to restrict driving or the measure of opening circuit temporarily, not only accounts for the road time long, to social and traffic impact is large.And be subjected to the restriction of construction organization, and structure is subjected to disturbance larger, and construction quality is difficult to meet the demands.Except the difficulty of the upper existence of constructing, also there are all drawbacks, many such as airborne dust, noise is large, the duration is tediously long; The construction of opening circuit causes Vehicle By-pass, and peripheral path blocks up, and oil consumption increases.Precast assembly, large-scale hoisting machinery are adopted in the bridge rapid construction more, wherein take the self-traveling module Transport Machinery as nucleus equipment, bridge superstructure is carried out whole whole the building of tearing open, is to account for the most a kind of construction technology of road shortest time, construction, is called the integral bridge replacement technique.
In the prior art, the bearing load that is used for the equipment of packing that integral bridge tears down and build is low, turn to and control the defective that existence is difficult to overcome simultaneously, can't satisfy the integral body of large bridge and tear down and build and transport.
Summary of the invention
The invention provides a kind of reasonable in design, the device of packing that is used for the integral bridge displacement applied widely, it can carry out the modular dismounting combination of vehicle frame according to packing load, the vertical cross stiffness of vehicle frame is larger, can realize simultaneously and car and walking synchronously, guarantee to pack morphological stability and the walking flexibility of member.
The technical solution adopted in the present invention is as follows:
A kind of device of packing for the integral bridge displacement comprises vehicle frame, dynamical system, running gear and suspension, it is characterized in that the described vehicle frame of packing device adopts longitudinal spliced multimode combining structure; Described suspension is hydraulic suspension, and described intermodule passing ratio valve connecting fluid pressing system makes and respectively takes turns between centers and all carry setting.
In the specific embodiment, described vehicle frame is box longitudinal beam structure, and each module has four symmetrically arranged tires, and the middle part of each module arranges the top jacking cylinder.。
In one embodiment, the described device of packing adopts CAN bus communication control dynamical system and turns to and running gear described CAN bus communication connection controller and sensor.
In another embodiment, described hydraulic lift system comprises the suspended axle that links to each other with vehicle frame, the described suspended axle suspension hydraulic oil cylinder that has been linked and packed, and the wheel shaft left-right swing type is installed in an end of suspended axle.
In one embodiment, the described device of packing also comprises a steering, and this steering comprises hydraulic driving oil cylinder and every group of rotary angle transmitter that suspension arranges of respectively independent control.
In one embodiment, described running gear is all-hydraulic enclosed drive system, comprises volume adjustable hydraulic pump and variable hydraulic motor, and described volume adjustable hydraulic pump and variable hydraulic motor drive the wheels setting by planetary reducer.
In one embodiment, what being provided with at least of described vehicle frame connected another vehicle frame all carries beam, the described beam described vehicle frame that is rigidly connected that all carries.
The vehicle frame of packing device that should be used for the integral bridge displacement adopts box longeron, has larger vertical bending moment, and load can be directly passed to the suspension wheel shaft, and the transverse bending moment of vehicle frame is very little.Vertically sliceable module combinations structure is convenient to the assembling of disassembled for transport and building site.The control of CAN bus communication can be finished the accurate control to drive system, steering, and can realize the anti-skidding and synchronization control of driving wheel.Hydraulic lift system can realize all carrying of each wheel shaft, and suspension links to each other with vehicle frame by suspended axle, has supporting capacity large, the advantage that steering resistance is little.Wheel shaft is installed in the suspension, can swing, and can adapt to the cross fall on road surface.Handling maneuver mode passing ratio control valve adopts hydraulic pressure independent steering and multi-mode steering, and usable direction dish operation in driver's cabin also can be carried out automatic deviation correction control by microelectronic device.
Beneficial effect of the present invention is, should be used for the integral bridge displacement to pack apparatus structure reasonable in design, applied widely, it can carry out the modular dismounting combination of vehicle frame according to packing load, the vertical cross stiffness of vehicle frame is larger, can realize simultaneously and car and walking synchronously, guarantee to pack morphological stability and the walking flexibility of member.
