Distance is set to 30mm.
Jacking is filled at gap after finishing using 30mm thickness rubber blankets, and control hook hydraulic cylinder 143 works, and will link up with 142
Be clipped on side form, then control ejection hydraulic cylinder 151 is ejected, by the perfusion cave mould ejection track plates on mould, make track plates with
Bed die is completely separated, and ejection hydraulic cylinder 151 is withdrawn after separation.
After track plates and bed die are completely separated and rubber blanket has been filled in gap, jacking hydraulic cylinder 131 is withdrawn, withdrawn traversing
Hydraulic cylinder 138, jacking position is removed by jacking hydraulic cylinder 131, and last crane lifting is loose in transhipment track plates to specified location
Hook hydraulic cylinder 143 is opened, stripping operation is completed, is risen when trigger lands and is used the first suspension bracket supporting leg 117 and the second suspension bracket supporting leg 118
It is supported.
To sum up, demolding of track slab hoisting machine of the invention and track plate prefabrication system are using the main body for being provided with jacking apparatus
Suspension bracket combination control system carries out the intelligent demoulding, and four jacking hydraulic cylinders can be carried out by remote control remote control magnetic valve
The control of concrete behavior, and in the presence of synchronous valve, four jacking hydraulic cylinder synchronous jackings are controlled when plate is played, receive each point
Power is uniform, and outer displacement sensor, and automatic monitoring each point jacking synchronous situation, real-time adjustment electromagnetism valve opening can be controlled in real time
Hydraulic cylinder jacking speed processed, it is ensured that each point displacement synchronous in knockout course.This invention realize the automation of demolding of track slab with
Precision, it is time saving and energy saving, eliminate because of the error influence that manual hand manipulation produces, the setting of synchronous valve and displacement transducer is protected
Each point uniform force and displacement synchronous during jacking are demonstrate,proved, can effectively have been eliminated because each stress point unbalance stress, displacement are asynchronous
And the visible crack occurred at arrisdefect, chip off-falling and the lifting sleeve pipe for producing.
The preferred embodiments of the present invention are these are only, is not intended to limit the invention, for those skilled in the art
For member, the present invention can have various modifications and variations.All any modifications within the spirit and principles in the present invention, made,
Equivalent, improvement etc., should be included within the scope of the present invention.
