In building the process of high speed railway, need to use beam transportation vehicle that the beam sheet is transported to the bridge erection scene from Liang Chang, need afterwards beam transportation vehicle to dock with Bridge Erector and complete bridging operation.In order to guarantee transportation safety, after lifting beam machine is placed on the beam sheet on beam transportation vehicle, must carry out the leveling work of beam transportation vehicle car load, to guarantee that the beam sheet can run-off the straight in transportation.After beam transportation vehicle arrived safe and sound the scene of setting up, in order to guarantee that beam transportation vehicle can be good at docking with Bridge Erector, this moment, beam transportation vehicle also will carry out suitable lifting according to the needs of Bridge Erector.
Traditional beam transportation vehicle lifting levelling control system just can be completed by two cover operating system co-operate.Its signal input apparatus is comprised of a control handle and an operation knob, the user can only realize the lifting of car load by the control handle on guidance panel, and the lifting of single-point also will realize the lifting that beam transportation vehicle is left front, right front, left back, right back by the jacking system operation knob on guidance panel.This kind control system can only realize lifting and the leveling of beam transportation vehicle single-point and car load, can not realize lifting and the leveling of two point, and need to use simultaneously control handle and operation knob could realize corresponding function, user's relative complex that operates.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel girder delivery vehicle lifting levelling control system, all functions with whole beam transportation vehicle front, rear, left and right and car load lifting, only just make the control of the descending operation that this system can the whole suspension of complete independently beam transportation vehicle by this signal input apparatus of control handle, and be infinite speed variation during lifting, operate easier, and can realize lifting and the leveling of beam transportation vehicle two point, make beam transportation vehicle lifting and leveling system optimization.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of Novel girder delivery vehicle lifting levelling control system, comprise signal input apparatus, programmable logic controller (PLC), proportional multi-way valve and elevating ram, described signal input apparatus comprises control handle, be used for controlling the lifting of car load, described control handle is equipped with two elevating control buttons as signal input apparatus its top, two potentiometric pickups are equipped with in described control handle inside, described potentiometric pickup be connected proportional multi-way valve and all directly be connected with described programmable logic controller (PLC), described proportional multi-way valve directly is connected with described elevating ram; After pressing above-mentioned elevating control button, promote described control handle to different directions, potentiometric pickup in described control handle sends to described programmable logic controller (PLC) with the operational factor that detects, after described programmable logic controller (PLC) carries out calculation process, send instruction to described proportional multi-way valve, described proportional multi-way valve promotes described elevating ram action, finally makes beam transportation vehicle complete the lifting action of corresponding two point or single-point.
Compare with traditional beam transportation vehicle lifting levelling control system, beam transportation vehicle lifting levelling control system of the present utility model will need two operating systems to act on simultaneously just completing of task only to be converted into control system of needs and can to complete smoothly, and be infinite speed variation during lifting, operate easier, and can realize lifting and the leveling of beam transportation vehicle two point, make beam transportation vehicle lifting and leveling system optimization.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, control handle, 2, elevating ram, 3, proportional multi-way valve, 4, programmable logic controller (PLC).
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described.
as shown in Figure 1, Novel girder delivery vehicle lifting levelling control system of the present utility model, comprise signal input apparatus, programmable logic controller (PLC) 4, proportional multi-way valve 3 and elevating ram 2, described signal input apparatus comprises control handle 1, be used for controlling the lifting of car load, described control handle 1 is equipped with two elevating control buttons as signal input apparatus its top, two potentiometric pickups are equipped with in described control handle 1 inside, described potentiometric pickup is connected with proportional multi-way valve and all directly is connected with programmable logic controller (PLC) 4, described proportional multi-way valve 3 directly is connected with elevating ram 2.
After pressing above-mentioned elevating control button, promote control handle 1 to different directions, the linear change occurs in the sensor current potential meter resistance in control handle 1, the voltage signal that produces is input to programmable logic controller (PLC) 4, described voltage signal is to reflect the openings of sizes of the electromagnetic valve of controlling elevating ram 2 liftings and the signal of speed, after programmable logic controller (PLC) 4 carries out calculation process, send instruction to proportional multi-way valve 3, proportional multi-way valve 3 promotes elevating ram 2 actions, finally makes beam transportation vehicle complete the lifting action of corresponding two point or single-point.
The single-point leveling: press the elevating control button, control handle 1 to the upper left, upper right, lower-left, lower right when promoting, corresponding beam transportation vehicle rises or descends to left front, right front, left back, right back single-point.
The two point leveling: press the elevating control button, when control handle 1 promoted to the front, rear, left and right direction, the leading portion of corresponding beam transportation vehicle, trailing portion, left half, right half two point rose or descend.
The car load leveling: do not press the elevating control button, when promoting, car load descends control handle 1 to the dead ahead, and when promoting, car load rises control handle 1 to the dead aft.
Beam transportation vehicle lifting levelling control system of the present utility model, the elevating control button is arranged on control handle 1, also in control handle 1 inside, two potentiometric pickups are housed, can not only realize by control handle 1 lifting of car load like this, the all functions that also have whole beam transportation vehicle front, rear, left and right and car load lifting, the control of descending operation that can the whole suspension of complete independently beam transportation vehicle, be infinite speed variation during lifting, operate easier, and can realize lifting and the leveling of beam transportation vehicle two point, make beam transportation vehicle lifting and leveling system optimization.
