Abstract
The utility model relates to a hydraulic flat pushing device which is characterized in that the hydraulic flat pushing device is mounted on the top end of a pier upright post which serves as a support. The hydraulic flat pushing device is composed of a base, a top raising hydro cylinder, a sliding block and a flat pushing hydro cylinder. The base is fixedly connected with the top end of the pier upright post, the top raising hydro cylinder is mounted on one end of the base, the flat pushing hydro cylinder is mounted on the other end of the base, and the flat pushing hydro cylinder is connected with the sliding block which is positioned in a sliding slot at the middle of the base. The sliding block bottom is provided with an antifriction board. The hydraulic flat pushing device has the advantages that the movement of the continuous beam is realized by the horizontal motion of the flat pushing hydro cylinder, and because the self-equilibrium of horizontal force in a flat pushing unit has no action of the horizontal force to the pier upright post and only has vertical load, upright post stress is improved and a mass of reinforce work of the upright post is saved.
Description
Technical field
The utility model relates to a kind of hydraulic means, particularly a kind of hydraulic pressure horizontal pulling device.
Background technology
Now, the continuous beam of multispan steel box structure at home and abroad highway bridge and the overhead road of city bridge in more and more be used, the continuous beam of this form adopts incremental launching method or traction method construction mostly, can finish the construction of setting a roof beam in place under the situation of close traffic not.Continuous beam can produce horizontal force to pier column by each when supporting pier column point because horizontal force is huge and on pier column the top, so very unfavorable for the pier column structure.
Summary of the invention
The purpose of this utility model is to produce the existing stressed disadvantageous problem to pier column of horizontal force to supporting pier column during continuous beam sets up in the solution prior art, and a kind of hydraulic pressure horizontal pulling device is provided.The utility model designs a kind of hydraulic pressure horizontal pulling device, it is characterized in that: on the pier column top as support level the hydraulic pressure horizontal pulling device is installed.The hydraulic pressure horizontal pulling device is made up of base, jacking cylinder, slide block peace push oil cylinder, base is fixedlyed connected with the pier column top, on an end of base jacking cylinder is installed, at the other end of base the horizontal sliding oil cylinder is installed, the horizontal sliding oil cylinder connects the slide block that is arranged in chute in the middle of the base.Slider bottom has the antifriction plate.The utility model has the advantages that by moving horizontally of horizontal sliding oil cylinder and realize moving of continuous beam, and the self-balancing of horizontal force in the horizontal sliding unit will not have the effect of horizontal force to pier column, only have only vertical load, improve the stressed of column, saved the reinforcement of a large amount of columns.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 be of the present utility model in application continuous beam place initial schematic diagram,
Accompanying drawing 3 be of the present utility model in application the schematic diagram of continuous beam after by jacking,
Accompanying drawing 4 for of the present utility model in application continuous beam be placed on schematic diagram on the slide block,
Accompanying drawing 5 is the schematic diagram that continuous beam moves forward with slide block in application of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated,
The specific embodiment
On pier column 5 tops the hydraulic pressure horizontal pulling device is installed among the figure as support level.The hydraulic pressure horizontal pulling device is made up of base 1, jacking cylinder 2, slide block 3 peaceful push oil cylinder 4, base 1 is fixedlyed connected with pier column 5 tops, on an end of base 1, jacking cylinder 2 is installed, the other end at base 1 is equipped with horizontal sliding oil cylinder 4, and horizontal sliding oil cylinder 4 connects the slide block 3 that is arranged in base 1 middle chute 6.Antifriction plate 7 is arranged at slide block 3 bottoms, and the sheet material that antifriction plate 7 is made for a kind of macromolecular material has very little friction factor, is made by Hualong Mechanical Engineering Co., Ltd., Zhengzhou, and model is the commercially available prod of MEG.
In the use, can finish moving of continuous beam to step shown in Figure 5 according to Fig. 2, at first continuous beam is hung on the hydraulic pressure horizontal pulling device that is installed in pier column 5 tops with crane, jacking cylinder 2 is with continuous beam jack-up then, horizontal sliding oil cylinder 4 retractions reset subsequently, and then with jacking cylinder 2 retractions, continuous beam is fallen on the slide block 3 of hydraulic pressure horizontal pulling device again, horizontal sliding oil cylinder 4 pushing tow slide blocks 3 move a step-length along base 1 middle chute 6 subsequently, then again again with continuous beam jack-up, horizontal sliding oil cylinder 4 retractions reset again, and the horizontal sliding installation of continuous beam is finished in running so continuously, owing to be placed with antifriction plate 7 at slide block 3 bottom pads, therefore can reduce the frictional force of horizontal direction more, reduce to replace the active force that weight moves, what make that whole pier column 5 is subjected to is vertical load, guarantees the Stability Analysis of Structures of pier column 5.
