Description

A kind of prestress concrete box girder hydraulic internal mold car and hydraulic internal mold system
Technical field
The present invention relates to a kind of hydraulic internal mold device of producing railway, highway, the employing of urban road bridge prestress concrete box girder.
Background technology
PC Box Girder Structure is simple, elegant in appearance, easily manufactured, supporting capacity is strong, dominate in railway, highway, urban road bridge, it is produced the prefabricated and bridge location of branch factory and builds two kinds, and main production process has mould installation, reinforcing bar binding, concreting and maintenance, mould dismounting etc.Case beam production mould is made up of internal mold, external mold wing plate mould, side form and end mould and supporting basis, and its internal mold generally is made up of polylith template and braced structures thereof, installs and removes by manually carrying out.Its weak point is that operating environment is poor, labour intensity is big, production efficiency is low.
Application number provides a kind of full-automatic hydraulic prefabricated box girder inner formwork system for 200610201284.6 Chinese patent, the inner formword of this system is by backform and a pair ofly go up the inner corner trim mould and a pair of down the inner corner trim mould is hinged forms, going up oblique oil cylinder is connected between backform and the last inner corner trim mould, oblique oil cylinder is connected between inner corner trim mould and the following inner corner trim mould down, be interval with bracing frame in the cavity bottom central authorities that inner formword is enclosed along case beam depth, set up rail on the bracing frame, walking translation dolly on the rail, the translation dolly comprises travelling wheel, a vehicle frame and a seat beam that is fixed on the vehicle frame, the vehicle frame of translation dolly extends to outside the inner formword, lays hydraulic power unit and operating desk on it.The translation dolly can whole be walked, and has made things convenient for the integral body of internal mold to come in and go out.
But, middle template in the said system and top template adopt rotating stripping demoulding, its weak point is: rotating stripping demoulding is undesirable because of the angle of power that hydraulic jack applies, can produce very big component, the part of hydraulic jack applied force makes the template rotation, plays the effect of the demoulding, part component there is no help to the rotation of template, but directly bear by formwork structure, pass to the center hinge of rotation, cause demoulding difficulty; In addition, because the existence of above-mentioned harmful component, the needed rigidity of template is bigger, and the template materials are more, and the needed segment of rotating stripping demoulding space is bigger.
Summary of the invention
Technical problem to be solved by this invention is the problem that solves demoulding difficulty in the hydraulic internal mold devices that prestressed concrete box girder adopted such as railway, highway, urban road bridge.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention provides a kind of prestress concrete box girder hydraulic internal mold car, comprise the combined inner mold plate, some hydraulic jack groups, vertical shift dolly and some groups of struts, described vertical shift dolly is arranged in the internal cavities of combined inner mold plate and moves along the longitudinal axis of combined inner mold plate, described combined inner mold plate comprise top template, about in template and left and right sides lower bolster, template and left and right sides lower bolster are hinged respectively in about described, described top template respectively with about the end face butt of middle template; Described hydraulic jack group comprise the top template telescopic oil cylinder, about in template telescopic oil cylinder and left and right sides lower bolster telescopic oil cylinder, described top template telescopic oil cylinder and about in the cylinder body of template telescopic oil cylinder and piston rod hinged with the inner surface of vertical shift dolly and top template, middle template respectively, the cylinder body of described left and right sides lower bolster telescopic oil cylinder and piston rod are hinged with lower bolster and middle template respectively; Described top template, about on the inner surface of template and left and right sides lower bolster and be respectively equipped with some adjustable strut fixed hinged seats on the vertical shift dolly.
The cross section of template is that three bendings are tabular in about described, and its top bending part is parallel with top template respectively.The cross section of described top template is up-small and down-big trapezoidal, described about in the end face of top bending part of template be the inclined-plane and contact with the inclined end face of top template.
Described every group of strut comprises adjustable strut and sleeve strut, and described adjustable strut comprises top template strut, middle form spreader and lower bolster strut, and the two ends of described top template strut, middle form spreader and lower bolster strut are respectively equipped with and are connected free bearing.Described sleeve strut is made up of a jacket casing and a tube core that is inserted in the jacket casing, and jacket casing is connected with the following bending part and the vertical shift cart stationary of middle template inner surface respectively with the other two ends of tube core, is respectively equipped with fixed pin shaft on jacket casing and the tube core and installs through hole.
Also comprise bracing piece and following bracing piece, described last bracing piece is fixedlyed connected with the adjacent inner surface of jacket casing and middle template respectively with following bracing piece two ends with the both sides up and down and the last bracing piece of the jacket casing that following bracing piece is separately positioned on.
The following bending part of template inner surface during the pin joint of template telescopic oil cylinder and middle template is arranged in about described.
At least four of described top template telescopic oil cylinders are respectively perpendicular to the soffit of top template.
Described vertical shift dolly comprises binding-beam and some driving wheels of two girders that be arranged in parallel, the described girder of some connections, and described driving wheel is by motor-driven.
