Abstract
The utility model discloses an automatic control pre-framing device for a steel box girder. The automatic control pre-framing device for the steel box girder comprises a plurality of hydraulic jacks which are vertically arranged, wherein the hydraulic jacks are connected with a hydraulic control board. According to the automatic control pre-framing device for the steel box girder adopting the technical scheme, springing parameters of the steel box girder can be accurately controlled, high framing efficiency is obtained and special three-dimensional springing of the steel box girder can be realized. Due to the adoption of a hydraulic system, the steel box girder with heavy weight can be supported; the automatic control pre-framing device is especially suitable for pre-framing large-sized steel box girders; and the hydraulic control board is convenient for operation and high in framing efficiency; and a complex mould producing process is omitted, and thus the production cost is reduced.
Description
Technical field
The utility model relates to a kind of assembly unit device of steel case beam, relates in particular to a kind of steel case beam preparatory assembly unit device of control automatically.
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
Goal of the invention: the purpose of the utility model is the deficiency to prior art, provides a kind of and can accurately control steel case beam arch camber parameter, and assembly unit efficient is high, can realize that the steel case beam of steel case beam space three-dimensional curve arch camber is controlled preparatory assembly unit device automatically.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model 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 utility model 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 the utility model assembly unit beam is convenient to implement, and be fit to suitability for industrialized production, and control accuracy is high.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, through a most preferred embodiment, the utility model technical scheme is elaborated, but the protection domain of the utility model is not limited to said embodiment.
As shown in Figure 1; A kind of steel case beam is the preparatory assembly unit device of control automatically; Comprise the hydraulic jack 1 that plurality of vertical is arranged, confirm to be provided with the quantity of hydraulic jack according to quantity, quality and the size of steel case beam, described hydraulic jack 1 is connected with hydraulic control panel 2; The hydraulic jack of described vertical layout per four as one group, each group is connected with hydraulic control panel respectively.Adopt the reasonable position of the fulcrum of ansys force analysis computed in software tapping case beam 3; Under each steel case beam, arrange four hydraulic jack according to reasonable fulcrum; With flat car for transport of sills steel case beam is placed on the hydraulic jack position piecemeal, utilizes 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; Detect linear qualified back bridge location matching parts 4 is installed, when bridge location sets up, utilize bridge location matching parts 4 to reset and set up.
