The carrying device comprises a vehicle frame, a motive power system, a running system and a hanging system, and is characterized in that the vehicle frame of the carrying device adopts a multi-module combined structure in longitudinal split joint, the hanging system is in hydraulic hanging, and modules are connected with the hydraulic system through a proportioning valve, so that wheel axles are in uniform loading arrangement. The carrying device for the bridge overall replacement has the advantages that the structure design is reasonable, the application range is wide, the modular dismounting and mounting combination of the vehicle frame can be carried out according to the carrying load, the longitudinal and transverse rigidity of the vehicle frame is higher, meanwhile, the parallel operation and the walking synchronization can be realized, and the morphological stability and the walking flexibility of carrying components are ensured.
Description
Technical field
The utility model belongs to integral bridge replacement technique equipment, carries out the device of packing that integral bridge loads transportation while 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 original place to original bridge remove to be rebuild, and often takes to restrict driving or the measure of opening circuit during construction temporarily, not only account for the road time long, to social and traffic impact is large.And be subject to the restriction of construction organization, and structure is subject to disturbance larger, and construction quality is difficult to meet the demands.Except the difficulty of the upper existence of constructing, also there is all drawbacks, such as airborne dust is many, 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.Bridge rapid construction adopts precast assembly, large-scale hoisting machinery more, Yi Shizhan road shortest time, construction be the most a kind of construction technology, machinery is nucleus equipment, bridge superstructure is carried out to whole whole the building of tearing open, Shi Zhan road shortest time, construction be the most a kind of construction technology, is called integral bridge replacement technique.
In prior art, the bearing load of the equipment of packing of tearing down and building for integral bridge is low, turn to and control the defect that upper existence is difficult to overcome simultaneously, and the integral body that cannot meet large bridge is teared down and built and transported.
Utility model content
The utility model provides a kind of reasonable in design, the device of packing for 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 synchronous, the morphological stability and the walking flexibility that guarantee to pack member.
The technical scheme that the utility model adopts is as follows:
Integral bridge displacement pack a device, comprise vehicle frame, dynamical system, running gear and suspension, the vehicle frame of packing device described in it is characterized in that adopts longitudinal spliced multimode combining structure; Described suspension is hydraulic suspension, and described intermodule passing ratio valve connecting fluid pressing system, makes respectively to take 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 top jacking cylinder.。
In one embodiment, described in pack device and adopt CAN bus communication control dynamical system and turn to and running gear, described CAN bus communication connects controller and sensor.
In another embodiment, described hydraulic lift system comprises the suspended axle being connected with vehicle frame, the described suspended axle suspension hydraulic oil cylinder that has been linked and packed, and wheel shaft left-right swing type is arranged on one end of suspended axle.
In one embodiment, described in pack device and also comprise a steering, this steering comprises the independent hydraulic driving oil cylinder of controlling and every group of rotary angle transmitter that suspension arranges respectively.
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 wheels setting by planetary reducer.
In one embodiment, what being at least provided with of described vehicle frame connected another vehicle frame all carries beam, the described beam described vehicle frame that is rigidly connected that all carries.
Should adopt box longeron for the vehicle frame of packing device of integral bridge displacement, and have larger vertical bending moment, load can be directly passed to suspension wheel shaft, and the transverse bending moment of vehicle frame is very little.Longitudinally sliceable module combining structure, is convenient to disassembled for transport and building site assembling.CAN bus communication is controlled, and can complete 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 is connected with vehicle frame by suspended axle, has supporting capacity large, the advantage that steering resistance is little.Wheel shaft is arranged on and hangs above, 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 in driver's cabin, the operation of usable direction dish, also can carry out automatic deviation correction control by microelectronic device.
The beneficial effects of the utility model are, should for 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 synchronous, the morphological stability and the walking flexibility that guarantee to pack member.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
