Abstract
The invention discloses an automatic control pre-assembly device for steel box girders. The automatic control pre-assembly device for the steel box girders comprises a plurality of vertically arranged hydraulic jacks which are connected with a hydraulic control console. According to the automatic control pre-assembly device for the steel box girders, springing parameters of the steel box girders can be controlled precisely, the assembly efficiency is high, and an effect of spatial three-dimensional curve springing of the steel box girders can be achieved. The invention also discloses a method for assembling the steel box girders by adopting the automatic control pre-assembly device for the steel box girders. The method comprises the following steps of: calculating rational pivot positions of the steel box girders through stress analysis software; arranging a plurality of hydraulic jacks below each steel box girder according to the rational pivot; controlling the hydraulic jacks by using the hydraulic control console to adjust the heights as well as the longitudinal and transverse directions of the steel box girders to achieve a steel box girder bridging linear effect; and arranging bridge matching pieces. The method is convenient to implement, suitable for industrial production and high in control precision.
Description
Technical field
The present invention relates to a kind of assembly unit device of steel case beam, relate in particular to a kind of steel case beam preparatory assembly unit device of control automatically; The invention still further relates to the said steel case beam method of the preparatory assembly unit device jointing steel box beam of control automatically of utilizing.
Background technology
The preparatory assembly unit of domestic and international existing steel case beam is divided into and utilizes moulding bed arch camber technology to realize steel case beam arch camber and utilize steel case beam length and the arch camber of matching parts thickness realization steel case beam.The moulding bed arch camber comparatively bothers, and efficiency of construction is low, and cost is big.Utilize steel case beam length and matching parts arch camber, precision is low, and it is linear to react the bridge location steel box beam erection more really.Daxie, the Zhejiang second bridge steel case beam is divided into straightway, the section of broadening and relaxes three kinds of forms of curved section; Bridge axis shape is the space three-dimensional curve that vertical curve and horizontal curve constitute; Adopt preparatory assembly unit moulding bed to make steel case beam, when assembly unit different segment in advance, need each transformation of the way moulding bed, and can not design moulding bed accurately; Cause steel case beam making error big, the size Control inaccuracy.
Summary of the invention

Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the present invention adopted is:
A kind of steel case beam is the preparatory assembly unit device of control automatically, comprises the hydraulic jack that plurality of vertical is arranged, described hydraulic jack is connected with hydraulic control panel.
The hydraulic jack of described vertical layout per four as one group, each group is connected with hydraulic control panel respectively.
A kind of big shaped steel case beam is controlled pre-assembly method automatically; Adopt the reasonable position of the fulcrum of force analysis computed in software tapping case beam; Under each steel case beam, arrange several hydraulic jack according to reasonable fulcrum; Utilize hydraulic control panel control hydraulic jack to carry out steel case deck-molding journey and vertical and horizontal adjustment, it is linear to reach steel box beam erection, and the bridge location matching parts is installed then.
Calculate four reasonable fulcrums of each steel case beam, arrange four hydraulic jack according to reasonable fulcrum below each steel case beam.
Adopt the reasonable position of the fulcrum of force analysis computed in software tapping case beam; Under each steel case beam, arrange four hydraulic jack; Utilize hydraulic control panel to carry out steel case deck-molding journey and vertical and horizontal adjustment; It is linear to reach steel box beam erection, and the bridge location matching parts is installed then, when bridge location sets up, utilizes the bridge location matching parts to reset and sets up.
Beneficial effect: the present invention compared with prior art, its beneficial effect is:
Hydraulic jack is arranged on the reasonable position of the fulcrum of steel case beam, through the rise drawdown parameter of hydraulic control panel control hydraulic jack, accurately controls each strong point height, has promptly guaranteed the arch camber parameter of steel case beam; The hydraulic jack scalable data is controlled, is convenient to regulate the position of each strong point of steel case beam; Adopt hydraulic system can support heavy weight steel case beam, be fit to the preparatory assembly unit of big shaped steel case beam; Hydraulic control panel is easy to operate, and assembly unit efficient is high, has removed complicated internal model making from, has reduced cost of production; The method of the big shaped steel case of assembly unit of the present invention beam is convenient to implement, and be fit to suitability for industrialized production, and control accuracy is high.
