In the utility model, top slippage parts 3 tops are provided with rubber pad 2, hold arch case beam by rubber pad 2, to satisfy partial pressing's requirement of arch case beam, protection arch case beam bottom paint.
Principle of the present utility model is by this cover incremental launching device, integrate jacking, translation, laterally adjust, realize arch case beam vertical, along bridge moving or adjusting to, direction across bridge, thereby guarantee the gradient, the full-bridge line style of arch bridge, and jacking force is become internal force, make bridge pier not bear horizontal load.This cover Lifting Equipment is made of upper and lower two parts.Two steps that this equipment utilizes " top " " to push away " hocket, and utilize jacking support cylinder 1 that the steel box girder integral is held up earlier; Utilize pushing tow translation oil cylinder 4 to push forward again; Afterwards the steel arched girder is placed on the bridge pier; Pushing tow translation oil cylinder 4 contracts cylinder on earth, continues to realize the next circulation that cycles through reciprocal pushing tow step, and final steel case beam is sent to preposition.
The concrete course of work of the present utility model is that original state pushing tow translation oil cylinder 4, jacking support cylinder 1 are in complete unloaded retracted mode; It is stressed that jacking support cylinder 1 is stretched cylinder, and load is transferred to above the jacking support cylinder 1 fully; Pushing tow translation oil cylinder 4 begins to stretch cylinder, stroke of steel case beam reach; Support jacking cylinder 1 withdrawal and put in place, load is transferred on the bridge pier support column fully; The 4 unloaded withdrawals of pushing tow translation oil cylinder; The above-mentioned action of reciprocation cycle is if the direction across bridge skew is then adjusted by laterally adjusting oil cylinder 5.
The utility model has a style of one's own, and under 12 controls of computer master controller, can realize jacking, move along the bridge, can also realize the adjustment of cross-bridges direction simultaneously, with line style and the slope requirement that adapts to different bridge type different directions.And this complete equipment becomes the internal force of system with jacking force, has overcome because the horizontal thrust that bridge pier is produced during other method pushing tow.By the control of hydraulic power unit 14, can adapt to the distortion of pushing tow arch case beam automatically, make the pushing tow safety and reliability.
