Detailed description of the invention
Support post of the present utility model adopts hydraulic telescopic type column, adopts fluid injection gun by triple-use valve fluid injection, realizes flexible object.
Main brace summer 1 is all equiped with four support posts 6 with secondary brace summer 4, and support post adopts the transformation of the way of DZ1.8 monomer oil cylinder pillar to form, and its minimum constructive height is 1310mm, and maximum height is 2000mm, and adjustment amount is 690mm.
The effect of jack 9 is the automatic relative movements realizing main brace summer and secondary brace summer, and the ultimate range of each movement is 700mm, and the front end of jack is hinged on main brace summer, and rear end is hinged on secondary brace summer.Jack adopts the turnover of operation control valve group hydraulic control oil, jack piston rod is stretched out or imperial year.
In order to increase the supporting intensity of main brace summer and secondary brace summer, at the both sides place of support post 6 position, reinforcement gusset is also set.
Move frame principle and step:
The first step: main brace summer 1 is in holding state, 8 support posts are all in stress, and main brace summer and secondary brace summer 4 position are parallel and self-consistent.
Second step: unload 4 root posts on main brace summer, main brace summer removes holding state, on the connection bracket 5 that the about 100mm and main brace summer can decline until fall is fixed on secondary brace summer beam, support post is also upwards packed up simultaneously, connection bracket fixing on main brace summer to decline about 100mm with main brace summer, but still links together with the sliding pin on secondary brace summer.Now secondary brace summer is still in holding state.
3rd step: operation control valve group, makes jack piston rod stretch out.Because secondary brace summer is still in holding state, then move frame jack piston rod when stretching out, main brace summer can be driven to move forward along slideway direction, and the connection bracket simultaneously on main brace summer can drive the sliding pin on secondary brace summer to move forward, and displacement is a step pitch 630mm.
4th step: main brace summer moves forward after a step pitch, on main brace summer four support posts are stretched out, and promote main brace summer and move up about 100mm until prop up top board, then main brace summer is in holding state.
5th step: unload 4 support posts on secondary brace summer, secondary brace summer removes holding state, and on the connection bracket 5 that the about 100mm and secondary brace summer can decline until fall is fixed on main brace summer, support post is also upwards packed up simultaneously.
6th step: operation control valve group, makes to move frame jack piston rod and retracts.Drive secondary brace summer to move forward, after the step pitch that moves forward, support post stretches out, and secondary brace summer enters holding state.
So far, one is moved frame circulation end.
After main brace summer column unloading of the present utility model, freely fall on bracket, its falling stroke is 100mm.This is in order to when mobile, prevents and top plate contact and the frictional resistance that produces.When main brace summer declines, connect bracket and also to decline 100mm, the bearing pin of sliding pin still all the time be connected bracket and link together.
Sliding pin of the present utility model be connected bracket and link together, only have degree of freedom in the vertical direction, in the horizontal direction then without relative motion.
And sliding pin and main brace summer or secondary brace summer have degree of freedom in the horizontal direction, can be free to slide, in the vertical direction then without relative motion.
