Abstract
The utility model discloses a transportation truck for steel truss girders of a bridge. The transportation truck is characterized in that walking mechanisms are arranged on the bottom of a frame (1), a support (4) for fixing steel truss girder members is arranged on the frame (1), and rotating supports (5) for stabilizing the steel truss girder members are arranged on the surface of the frame (1). The transportation truck can be used for transporting various members, can be applied to transportation under various conditions of longitudinal slopes and varying slopes, can be used for transporting the members with various lengths as two independent trolleys are connected with each other by a joining beam, and can implement long distance transportation without arrangement of cables along a transportation line as the walking mechanisms are provided with electric systems independently.
Description
Technical field
The utility model relates to a kind of steel truss girder bridge flat car for transport of sills, belongs to technical field of bridge engineering.
Background technology
In the prior art, the member installation unit transportation of steel truss girder bridge (comprises purlin sheet transportation, the bridge deck transportation, construction equipment transportation) be steel truss girder and the bridge deck of installation in position carry out, consider bridge district wind load, construction investment, the consideration of each factor such as construction safety, the bridge central side bridge deck of installing in advance are two separately bridge deck independently, do not form whole, therefore under this situation, carry out the transportation of steel truss girder member installation unit, can cause some negative consequences, the monolithic bridge deck of installation unit have the structural stability risk under the working load effect of steel truss girder component conveying, the malformation risk is also arranged, these all can affect the transportation of steel truss girder member, affect the installation accuracy of bridge deck, affect the installation quality of bridge deck.For large-scale steel truss girder member, bulky, normally member is transported to the below, installation site, lifted by loop wheel machine again.Because bridge bottom situation differs, some bridge bottom can't be transported the steel truss girder member by vehicle or steamer etc. and be put in place, so some bridge need to be considered to carry out transporting of steel truss girder member at the bridge floor of just having put up.
The utility model content
The purpose of this utility model is, a kind of steel truss girder bridge flat car for transport of sills is provided.Simple in structure, easy to operate, can there be slope change at bridge floor, bridge floor has normally operation under the operating mode such as knuckle, can also adapt to steel truss girder member situation different in size.
The technical solution of the utility model.Steel truss girder bridge flat car for transport of sills, bottom of frame is provided with walking mechanism, is provided with for the fixing support of steel truss girder member at vehicle frame, is provided with the swinging mounting for stabilized steel trusses member on the vehicle frame surface.
Described swinging mounting connects support bar, is provided with arc between swinging mounting and support bar.
The described linkage of regulating vehicle frame length that between walking mechanism, is provided with.
The strut of described support reinforcement by connection.
Described support is provided with soller.
Steel truss girder bridge flat car for transport of sills of the present utility model, the steel truss girder member is fixed on the vehicle frame by support, by the walking mechanism of vehicle frame the steel truss girder member is transported to the installation site, lifts again.Swinging mounting of the present utility model adopts the arc syndeton, can have slope change at bridge floor, and bridge floor also has in the situation of knuckle, all the time can with vehicle frame on steel truss girder member bottom keep a contact surface, normally load-bearing.And walking mechanism can reconcile length by linkage, solved a steel truss girder member difficult problem different in size in the transportation.Compare with prior art, the present invention has well solved: 1, the transportation of various members; 2, can be suitable for various longitudinal gradients and become transportation under the sloping condition; 3, the dolly by two platform independent connects with link rod, can transport the member of all lengths; 4, the electric system that carries of walking mechanism does not need to arrange cable along the line, can realize long-distance transportation.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the top view of accompanying drawing 1;
Accompanying drawing 3 is the structural representation of swinging mounting.
The specific embodiment
Embodiment of the present utility model.A kind of steel truss girder bridge flat car for transport of sills, as illustrated in fig. 1 and 2, walking mechanism 2 is installed in vehicle frame 1 bottom, installs at vehicle frame 1 to be used for the fixedly support 4 of steel truss girder member, on vehicle frame 1 surface the swinging mounting 5 that is used for stabilized steel trusses member is installed.
As shown in Figure 3, swinging mounting 5 connects support bar 6, and arc 7 is installed between swinging mounting 5 and support bar 6.Arc 7 and steel truss girder member bottom contact, can have slope change at bridge floor, and bridge floor also has in the situation of knuckle, all the time can with vehicle frame 1 on contact surface of steel truss girder member bottom maintenance.
The linkage 3 that is used for regulating vehicle frame 1 length is installed, to cooperate the steel truss girder member of different size between walking mechanism 2.Walking mechanism 2 comprises set of wheels, and set of wheels connects movable motor, and movable motor connects diesel-driven generator, electric control console again.
The strut 8 of reinforcement by connection on support 4, the intensity of raising support 4 is also installed soller 9, about the handled easily workman on support 4.
Operating process is as follows:
(1), at first open diesel-driven generator, behind the generating set working stability, operating personnel close the line breaker in the electric control console first, can operate.
(2), the start button plugged on the push panel, the power supply indicator that this moment, button carried is lighted.As stopping in emergency, the knob but the push platform stops in emergency is cut off the electricity supply in the course of the work.
(3), drive before, with the tinkle of bells notice other operating personnels of ground.
(4), the universal seclector on the guidance panel is used for the traveling action of walking mechanism.Be the second gear operation, zero-bit is stopped.Left-handed, advance, altogether second gear; Dextrorotation retreats, altogether second gear.
(5), when transportation during difform beam, the distance that walking mechanism is 2 should be adjusted.
Claims (5)
1. steel truss girder bridge flat car for transport of sills, it is characterized in that: vehicle frame (1) bottom is provided with walking mechanism (2), be provided with for the fixing support of steel truss girder member (4) at vehicle frame (1), be provided with the swinging mounting (5) for stabilized steel trusses member on vehicle frame (1) surface.
2. steel truss girder bridge flat car for transport of sills according to claim 1 is characterized in that: described swinging mounting (5) connects support bar (6), is provided with arc (7) between swinging mounting (5) and support bar (6).
