Description
Technical field
The pusher Beam transportation vehicle of the one that the haulage vehicle equipment and technology, particularly Bridge Erector that the present invention relates to bridge erection prefabricated case beam use in feeding beam process.
Background technology
In the transport of existing bridge erection prefabricated case beam (abbreviation beam) or feeding beam operation, main use fortune (carrying on the back) beam dolly transports (in fixed point lifting) or the transport of overhead traveling crane automatic moving (in non-fixed point lifting) have been come, and Beam transportation vehicle just bears merely a kind of vehicle arrangement of transport case beam.No matter be in the feeding beam process of that form, all need heavy-duty motor to drive wheels, transport along definitive orbit and arrive assigned address, then carry out the beam operation that falls.Because the weight of prefabricated case beam is very heavy, feeding beam process is inevitable slowly, time-consuming effort, inefficiency; And in non-fixed point lifting process, very high to the requirement of lifting wirerope, its maintenance cost also wants corresponding increase.In addition, the high energy consumption of feeding beam process is also obvious.
In fixed point lifting process, be the driving utilizing fortune beam dolly, be transported to by prefabricated case beam below Bridge Erector, before and after Bridge Erector, wire rope puts down by overhead traveling crane, and after prefabricated case beam and Bridge Erector suspension rod are connected, Jiang Liangshang carries, and completes bale handle action.This method hanging beam is simple, once completes, and it is also comparatively simple to control aspect, but due to when Beam transportation vehicle and lower nose girder contraposition, complicated operation, quite time-consuming power, cause whole hoisting process to need the longer time, efficiency is not high.
Someone devises a kind of feeding beam method of non-fixed point lifting, and to be prefabricated case beam one end to be sling advances by overhead traveling crane before Bridge Erector for it, and the other end runs on Beam transportation vehicle platform by carrying the dragging of beam dolly on the back.Before between them, the position of overhead traveling crane is measured by two position sensors respectively with the position of carrying beam dolly on the back, and carrying on the back between beam dolly and the control system of Bridge Erector on Beam transportation vehicle has data wire to be connected.Such structure complete machine is safe and reliable, and hanging beam is what to separate with the via hole action of lower nose girder, and there is not potential safety hazard, operating efficiency is high, and Beam transportation vehicle does not need to wait for that carrying returning of beam dolly on the back can open Hui Liangchang.But carry beam dolly on the back to walk with Bridge Erector overhead traveling crane and also need good cooperation, control relative complex.
Summary of the invention
For the deficiencies in the prior art, the technical problem that quasi-solution of the present invention is determined is: provide a kind of pusher Beam transportation vehicle.This Beam transportation vehicle is in conjunction with pushing away beam technology in building bridge construction process, coordinate fixed point hoisting type Bridge Erector, Bridge Erector is enable to separate the mismatch problem of commit point lifting and lower nose girder, system architecture is compact, reduces and carries beam dolly, overhead traveling crane usage quantity on the back, reduces energy ezpenditure, and make Beam transportation vehicle not only can transport prefabricated case beam, but also can separately or independent pushing prefabricated case beam arrive appointed place, use rigid slab to go to promote case beam, prefabricated case beam transports stable simultaneously.
The technical scheme that the present invention solves described Beam transportation vehicle technical problem is: design a kind of pusher Beam transportation vehicle, comprise cart, dolly, hydraulic pressure and electrical control system, it is characterized in that this Beam transportation vehicle also comprises fixed length propeller and hydraulic pressure creep machine;
