Abstract
The utility model relates to a double-girder type triangular truss bridge erecting machine which comprises a front support, a middle support, a back support, a girder and a crown block, wherein the front support and the back support are fixedly supported at front and back ends of the bottom of the girder respectively and adopt triangular structures; the middle support is located between the front support and the back support and comprises a pair of rolling wheels, and the girder is supported on the pair of rolling wheels; and the crown block is arranged at the top of the girder and can horizontally move along the girder. The double-girder type triangular truss bridge erecting machine does not occupy road resources and is high in structural strength, convenient to install, good in stability, safe to use and capable of saving the construction cost, facilitating determination of the prefabrication order of box girders and performing construction across roads, mountains and rivers.
Description
[technical field]
The utility model relates to a kind of building machinery, is specifically related to a kind of two-beam type triangular truss Bridge Erector, belongs to technical field of engineering machinery.
[background technology]
For alleviating the rapid growth of China's big and medium-sized cities traffic volume, urban rail transit construction is fast-developing.In built and urban rail traffic project that plan to build, aerial conveyor proportion is very large, and along with urban rail transit construction, the development to suburb extension and following outskirts of a town railway by urban district, will have increasing rail transit elevated bridge and be built to.
Case beam is the important component part of rail transit elevated bridge.The cast-in-place method of full framing that China's box girder construction generally adopts, although technology comparative maturity, reliable also exists many drawbacks, causes waste economically.At present, also have the construction method that adopts erecting whole opening box girder, but prefabricated case beam set up need crawler crane or turbine suspension bracket auxiliary, so not only take ground level road resource, but also can not under the complex-terrains such as river, mountains and rivers, construct.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel two-beam type triangular truss Bridge Erector, to overcome described defect of the prior art.
[utility model content]
For addressing the above problem, it is a kind of easy for installation that the purpose of this utility model is to provide, and good stability, does not take path resource and use safe two-beam type triangular truss Bridge Erector.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of two-beam type triangular truss Bridge Erector, it comprise before, middle holder, rear, girder and overhead traveling crane; Wherein, described before and rear rear and front end that is immobilizated in respectively girder bottom, both are structure triangular in shape all; Described middle restitope is between front, rear, and it comprises a pair roller, and described girder is supported on this pair roller; Described overhead traveling crane is arranged on the top of girder, and can be along girder translation.
Two-beam type triangular truss Bridge Erector of the present utility model is further set to: the bottom of propping up before described is provided with walking roller, and can be connected to the brake gear on walking roller.
Two-beam type triangular truss Bridge Erector of the present utility model is further set to: described girder is formed by connecting by several unit.
Two-beam type triangular truss Bridge Erector of the present utility model is also set to: described girder is provided with some reinforcing ribs that are inclined to set.
Compared with prior art, the utlity model has following beneficial effect: two-beam type triangular truss Bridge Erector structural strength of the present utility model is high, easy for installation, good stability, do not take path resource, use safety, save construction costs, convenient determine the beam prefabricated order of case, can cross over road, mountains and rivers, river and construct.

Fig. 2 is the lateral view of two-beam type triangular truss Bridge Erector of the present utility model.
Fig. 3 is the front structural representation propping up in Fig. 1.
Fig. 4 is the structural representation of middle holder in Fig. 1.
[detailed description of the invention]
Refer to Figure of description 1 to shown in accompanying drawing 4, the utility model is a kind of two-beam type triangular truss Bridge Erector, its by front 1, middle holder 2, prop up 3 afterwards, several parts such as girder 4 and overhead traveling crane 5 form.
Wherein, described before 1 and rear 3 rear and front end that is immobilizated in respectively girder 4 bottoms, both are structure triangular in shape all, thereby has good structural strength and stability.Before described, 1 bottom is provided with walking roller 5, and can be connected to the brake gear 6 on walking roller 5.Described walking roller 5 can facilitate this Bridge Erector to move.And described brake gear 6 can be fixed this Bridge Erector.
Described middle holder 2 front 1, prop up between 3 afterwards, it comprises a pair roller 7, described girder 4 is supported on this pair roller 7.In this, ask 2 can carry out as required position adjustment.
Described girder 4 is formed by connecting by several unit, thereby can change as required the span of girder 4.Be provided with some reinforcing ribs that are inclined to set 8 in described girder 4.
Described overhead traveling crane 5 is arranged on the top of girder 4, and can be along girder 4 translations.This overhead traveling crane 5 can play box beam, and case beam can be transferred to desired location.
Above detailed description of the invention is only the preferred embodiment of this creation, not in order to limit this creation, any amendment of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
