Description
Technical field
The utility model relates to a kind of equipment for bridge construction, particularly relates to a kind of large sections hoisting mechanism.
Background technology
The construction method of general cross a river, sea-bridge beam is first transported to by the steel box-girder assembled and is arranged on the fixed abutment that is in water, suspension cable is adopted to lock lift method again, carry out lifting operation segmentedly, because steel box girder segment deadweight is larger, the water surface cannot be set up support to support sections, therefore must lift a sections recycling suspension cable to lock installation sections, disturb under preventing sections.Need to use erection crane in this process, and often install a sections and just need to readjust the position of erection crane and the pulling force of suspension cable, guarantee bridge curve is correct, substantially increases the workload of construction, and reduces the efficiency of construction.The bridge that sections is more carries out erection & lift all need to carry out water surface blockade, if just constructed on busy navigation channel, the blockade of the water surface then can have a strong impact on the transport in navigation channel.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides a kind of a large amount of reduction of erection time, simplifies temporory structure thus the large sections hoisting mechanism of increasing economic efficiency.
The technical scheme that the utility model will adopt is: the utility model comprises the steel box-girder be fixedly installed on bridge pier, be welded by some little sections in across large sections, described large sections hoisting mechanism also comprise the beret truss be separately positioned on adjacent two described steel box-girder, at least two hydraulic lift(ing) cylinders being arranged on top, described beret truss one end and be arranged on described in across the hanger at large sections two ends, described hydraulic lift(ing) cylinder is identical with described hanger quantity, position relative, and is matched between two by cable wire.
Bottom described beret truss, be also provided with front fulcrum and rear fulcrum, described steel box-girder is also provided with connector, described front fulcrum top is fixedly connected with described beret truss, and described rear fulcrum and described connector are rotatedly connected.
The position of the corresponding described front fulcrum of described steel box-girder is also provided with dividing plate.
The beneficial effects of the utility model are: due to the utility model comprise the steel box-girder be fixedly installed on bridge pier, be welded by some little sections in across large sections, described large sections hoisting mechanism also comprise the beret truss be separately positioned on adjacent two described steel box-girder, at least two hydraulic lift(ing) cylinders being arranged on top, described beret truss one end and be arranged on described in across the hanger at large sections two ends, described hydraulic lift(ing) cylinder is identical with described hanger quantity, position relative, and is matched between two by cable wire.Compared with prior art, the utility model utilizes described bridge pier as supportive body, and described steel box-girder is supporting surface, then coordinating by described hydraulic lift(ing) cylinder and described hanger, closes up promoting across large sections in described.So the utility model structure is simple, effectively reduce the use amount of falsework and the workload of sections segmental hoisting, thus reach a large amount of reduction of erection time, simplify the objects such as temporory structure and the large sections hoisting mechanism of increasing economic efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the connection diagram of described rear fulcrum and described connector.
Detailed description of the invention
As depicted in figs. 1 and 2, the utility model comprises the steel box-girder 2 be fixedly installed on bridge pier 1, be welded by some little sections in across large sections 3, described large sections hoisting mechanism also comprise the beret truss 4, at least two be separately positioned on adjacent two described steel box-girder 2 be arranged on top, described beret truss 4 one end hydraulic lift(ing) cylinder 5 and be arranged on described in across the hanger 6 at large sections 3 two ends, described hydraulic lift(ing) cylinder 5 is identical with described hanger 6 quantity, position relative, and is matched between two by cable wire 7.
Bottom described beret truss 4, be also provided with front fulcrum 41 and rear fulcrum 42, described steel box-girder 2 is also provided with connector 21, described front fulcrum 41 top is fixedly connected with described beret truss 4, and described rear fulcrum 42 is rotatedly connected with described connector 21.The position of the corresponding described front fulcrum 41 of described steel box-girder 2 is also provided with dividing plate.
The utility model utilizes the described bridge pier 1 be arranged in water as braced structures main body, the described steel box-girder 2 be fixedly installed on above described bridge pier 1 is supporting surface, such design makes engineering utilize the permanent structure of bridge self as much as possible, thus reduces the use of falsework.At the upper surface of described steel box-girder 2, described front fulcrum 41 and described rear fulcrum 42 are provided with described beret truss 4, it is assembled that described beret truss 4 adopts some pars to weld, and can adjust according to actual conditions such as the sizes of construction bridges structure.Described rear fulcrum 42 generally can adopt steel strand to be fixed on described steel box-girder 2 described beret truss 4 rear end, but in the utility model, described rear fulcrum 42 is rotationally connected with described steel box-girder 2 by the described connector 21 be fixedly installed on described steel box-girder 2.
The front position of described beret truss 4 upper surface is also provided with the hydraulic lift(ing) cylinder 5 described at least two, in the utility model, what described hydraulic lift(ing) cylinder 5 adopted is punching jack lifting means, this type of lifting means is that standard hydraulic components can adjust according to the change of lifting weight, is also convenient to buy use technology and changes.Prior complete by some little sections welding are assembled after described in be provided with the suitable hanger 6 of quantity, position and described hydraulic lift(ing) cylinder 5 across the upper surface place of large sections 3 rear and front end, be connected by cable wire 7 between described hanger 6 with described hydraulic lift(ing) cylinder 5.By coordinating of described hydraulic lift(ing) cylinder 5 and described hanger 6, by described across large sections 3 be promoted to suitable position and described steel box-girder 2-in-1 hold together, in the utility model, the quantity of described hydraulic lift(ing) cylinder 5 is two.
The utility model is applicable to cross a river crossing-fiver bridge construction field.
