Abstract
A vehicle-carried bridge-laying apparatus for laying movable and integrally foldable bridge is composed of laying unit, hydraulic supporter assemblage, hydraulic electric system and truck with chassis, and technically features that the laying unit is composed of expanding arm, expanding cylinder, tail axle, movable supporter, safety balancing cable, lifting cylinder, lifting cable assemblage and hydraulic electric follow-up system. The folded segments of bridge can be continuously expanded until reaching the desired bridge-laying position.
Description
The present invention relates to a kind of mechanized bridge stringer, particularly the bridge joint is the stringer of the vehicular travelling bridge of foldable integral formula structure.
Existing vehicle carrying movable bridge erecting apparatus bridge formation motion rule mark is overturn-overturn-to turn over, and makes collapsible spanning leave chassis, opens up directly, reaches appointment bridge formation position.Though can finish the bridge formation task of defined, the center of gravity of overturning for the second time is too high, and security reliability is low; Finish for the second time and just can overturn for the third time after the upset, thereby prolonged the activity duration; Upset back wind area increases for the second time, and blast is the higher hidden danger that also increased of point with joint efforts; Part work will manually be finished, and has increased certain labour intensity.China Patent No. is 94112310 disclosed vehicle carrying movable bridge erecting apparatus, is made up of principal arm, master cylinder, main rope, hydraulic capstan, auxiliary, auxiliary oil cylinder, control box, leading block, crossbeam, hook, hook oil cylinder, push rod, cable wire etc.Its motion rule mark of building bridge is hang-overturn-to hang, and it is straight to make folding spanning leave the chassis car exhibition, reaches to specify the bridge formation position.Also there is certain limitation in this bl bridge layer, mainly contains (1) handling center of gravity height, and security reliability is poor; (2) the intermittence mechanical work has prolonged the activity duration; (3) operation sequence is many, and labour intensity is also higher.
Task of the present invention is the deficiency that overcomes above-mentioned bl bridge layer, and a kind of improved vehicle carrying movable bridge erecting apparatus is provided, and this device can carry out continuous mechanized operation reliably, and sets up or remove weak point between the time receiving, and simple to operate, labour intensity is low.
Task of the present invention realizes by following scheme: it is made up of stringer, supporting leg assembly, liquid electrical system and chassis.Stringer by principal arm, master cylinder, auxiliary, auxiliary oil cylinder, exhibition straight-arm, open up straight oil cylinder, the oil cylinder that traverses, hoist cylinder, tailing axle, hydraulic capstan, main rope, insurance tail rope, halyard, leading block, the electric servomechanism of hydraulic pressure etc. form.Principal arm and master cylinder are arranged on the chassis afterbody crossbeam, and in the effect of master cylinder, principal arm can be holded up and fall down, and drive folding spanning and hold up together and fall down.Auxiliary and auxiliary oil cylinder are installed in the principal arm upper end, and the principal arm motion drives auxiliary and moves together, and under the auxiliary oil cylinder effect, auxiliary can rotate relative to principal arm, and is folding.Exhibition straight-arm and Zhan Zhi oil cylinder are installed in the principal arm lower end by two tailing axles.Under the effect of the straight oil cylinder of exhibition, the exhibition straight-arm can rotate relative to principal arm, and cooperatively interacts with auxiliary and hydraulic capstan, and the limit is put down the spanning limit and opened up straight spanning, thereby can improve the speed of bridging operation greatly, increases the stability of operation.The exhibition straight-arm is provided with two lift cylinders, under its effect, can mention and put down spanning.Between exhibition straight-arm and tailing axle, horizontal adjustment oil cylinder is set, but lateral moving bridge is striden under this oil cylinder effect, guarantees the lateral attitude of spanning when setting up.The hydraulic capstan system under the effect of hydraulic capstan, cooperates with auxiliary and exhibition straight-arm by hoist cable and train, can finish spanning folding, launch and transport operations such as spanning to fortune bridge car.Each cylinder action is realized by hydra-electric system, wherein opens up straight cylinder action and finishes by the electric servomechanism of liquid.The supporting leg assembly adopts oil cylinder to make supporting leg, and movable plinth sleeve-board is contained in the oil cylinder piston rod end, packs up automatically or puts down under the oil cylinder effect.
The present invention is by the evidence of repeatedly building bridge: can carry out the centre of gravity continuous mechanized safely and reliably and set up the operation overall process, when setting up, jack-knife bridge joint movement locus is simple, clear and definite, fixing, and upset and exhibition direct acting unite two into one, thereby operation realizes sequencing, simplification; Set up the activity duration shortening, single span set up about 4 minutes, and full-bridge sets up about 50 minutes and can finish, and labour intensity reduces greatly, and work such as a small amount of hook, unhook and control crank are only arranged.
