Abstract
The utility model discloses a railway flatbed bridge crane of carrying a load on back, a railway flatbed bridge crane of carrying a load on back include the girder, and the lower part of girder is equipped with many spinal branchs leg, and the upper portion of girder is equipped with the device of putting more energy into, and the lower part of girder still is equipped with hoist device, is equipped with the motorized cart between hoist device and the girder. To put up bridge crane carrys a load on the back on the railway flatbed to utilize the piggy -back -trailer on flatcar to wait the roof beam of building bridge, hoist device snatchs the bridge, and through motorized cart operation to the anterior position that need erect. Having improved transport speed by a wide margin, having utilized the existing equipment in the railway line, saved professional conveyor system, the construction is equipped simply, can put in order the hole and erect.
Description
Technical field
The utility model relates to a kind of Bridge Construction and bridge engineering emergency first-aid repair technology, particularly relates to a kind of railway platform truck and to carry a load on the back Bridge Erector.
Background technology
In technical field of civil engineering, especially in Bridge Construction technical field, little span bridge can adopt common Bridge Erector to set up, and unit spelling mode also can be adopted to set up, or adopts heavy suspension bracket to lift erection.On operating line, said method is also substantially adopted to carry out bridge erection in bridge engineering emergency first-aid repair technical field.
Common Bridge Erector needs supporting girder carrier to coordinate, and the efficiency of setting a roof beam in place is restricted; The speed of unit spelling mode is slow; Heavy loop wheel machine is difficult to river valley and the natural barrier place of arrival, and directly lifting erection is just infeasible.
Utility model content
The purpose of this utility model is to provide simple, the fireballing railway platform truck of a kind of construction and carrys a load on the back Bridge Erector.
The purpose of this utility model is achieved through the following technical solutions:
Railway platform truck of the present utility model is carried a load on the back Bridge Erector, comprise girder, the bottom of described girder is provided with many supporting legs, and the top of described girder is provided with reinforcer, the bottom of described girder is also provided with hanging apparatus, is provided with motorized cart between described hanging apparatus and girder.
The technical scheme provided as can be seen from above-mentioned the utility model, the railway platform truck that the utility model embodiment provides is carried a load on the back Bridge Erector, significantly improves travelling speed, make use of the existing equipment in railway line, save the transportation system of specialty, construction equipment is simple, can set up in whole hole.

In figure:
1 girder, 2 columns, 3 reinforcers, 4 liftings and motorized cart, 5 supporting leg one, 6 supporting leg two, 7 supporting leg three, 8 supporting leg four, 9 bearings, 10 treat bridge, 11 flat car one, 12 flat car two, 13 locomotives.
Detailed description of the invention
To be described in further detail the utility model embodiment below.
Railway platform truck of the present utility model is carried a load on the back Bridge Erector, its preferably detailed description of the invention be:
Comprise girder, the bottom of described girder is provided with many supporting legs, and the top of described girder is provided with reinforcer, and the bottom of described girder is also provided with hanging apparatus, is provided with motorized cart between described hanging apparatus and girder.
The front portion of described girder is provided with supporting leg one, supporting leg two, supporting leg three, supporting leg four from front to back successively, and described supporting leg one and supporting leg four are provided with folding or stretching device.
Railway platform truck of the present utility model is carried a load on the back the method that Bridge Erector realizes setting a roof beam in place, and comprises step:
Bridge Erector is carried a load on the back on railway platform truck, and utilizes flat car transport to treat bridge;
The supporting leg two of Bridge Erector, supporting leg three are fixed on flat car one;
Supporting leg one is folded, is supported on the bridge pier of front end or on front beam body;
By folding for leg four, bridge is passed through;
Hanging apparatus captures bridge, and is moved to the position need set up front portion by motorized cart.
Railway platform truck of the present utility model is carried a load on the back Bridge Erector, Bridge Erector main frame is carried a load on the back as main bridging equipment on railway platform truck, and utilize the locomotive of operation that the flat car of Bridge Erector of carrying a load on the back is shifted onto bridge formation place, namely Bridge Erector is front, locomotive is rear, and wait is set a roof beam in place.Bridge Erector front extends to treats frame aperture position place, and rear can adopt flat car to be fed into and treat bridge.Locomotive is withdrawn into beam making field or beam body reserve storage, and loading is treated that bridge formation place shifted onto by the flat car of bridge.Treat that bridge is assembled into entirety and sets up.Treat bridge feeding Bridge Erector rear portion, Bridge Erector is sling and is treated bridge, slides onto and treats frame aperture position place, and lower let-down beam, sets up complete.
Specific embodiment:
As shown in Figure 1 and Figure 2, railway platform truck Bridge Erector of carrying a load on the back comprises: girder 1, column 2, reinforcer 3, lifting and motorized cart 4, supporting leg 1, supporting leg 26, supporting leg 37, supporting leg 48, bearing 9.
Described girder can be steel box-girder, girder truss, when described girder rigidity is enough, can omit described column and described reinforcer.Described lifting and motorized cart can be sling treating bridge and with treating that bridge moves ahead.Described supporting leg two and described supporting leg three are supported on railway platform truck, are 〇 shape structure, are convenient to treat that bridge passes through.Described supporting leg one and described supporting leg four are accordion structure, open when needed and support.
The flat car one of bridge girder erection machine system of carrying a load on the back pushes to bridge location by locomotive, and described flat car one is temporarily anchored on circuit, move under preventing the effect of described flat car one outer load, described supporting leg one is supported on front end bridge pier or the beam face do not damaged, and described supporting leg two and described supporting leg three are fixed on described flat car one.
Described locomotive is withdrawn into beam making field or beam body reserve storage, loading is treated that the flat car two of bridge pushes the afterbody of described flat car one, packs up described supporting leg four, and bridge is treated in feeding, opens described supporting leg four and is supported on described flat car two.
Described lifting and motorized cart are sling and are treated bridge and from line slip to treating frame aperture position place, transfer bridge to bridge location place, bridge erection is complete.
The beneficial effects of the utility model may be summarized to be:
(1) utilize locomotive and flat car pallet bridge machine and treat bridge, significantly improve travelling speed.
(2) utilize locomotive and flat car pallet bridge machine and treat bridge, make use of the existing equipment in railway line, saving the transportation system of specialty.
(3) construction equipment is simple, can set up in whole hole.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
