Abstract
The utility model relates to a large-tonnage rubber-tyred girder transporting vehicle, and belongs to box-girder transport machinery on a high-speed railway. The girder transporting vehicle comprises a vehicle body, a main girder, a girder towing trolley which is arranged on a running rail on the top of the main girder as well as running wheel groups under the main girder, a steering mechanism arranged on the running wheel groups, a braking system as well as a power system, a hydraulic system and an electrical system. Two balancing hydraulic cylinders, which are arranged on the girder towing trolley, and the two fixed stays of a bearing beam on the front end of the girder transporting vehicle form a supporting box-girder with a three-point balanced system; the girder towing trolley is connected with a wound roll of the hydraulic system through a chain pulley; a running hydraulic system adopts a variable displacement motor with a closed hydraulic drive circuit, and all other hydraulic systems in the vehicle adopt open hydraulic drive circuits; the steering mechanism adopts four steering cylinders and connecting bars, and crank arm systems, and each group of tyres has different rotation angles when in turning to achieve smooth and flexible turning; through the position adjustment of the girder towing trolley, girder sheets with different spans can be very conveniently transported, and a matching bridge machine can be transported piggyback to realize the diversion between bridges.
Description
Technical field
The utility model relates to a kind of large-tonnage rubber-tyred beam transportation vehicle, belong to the high speed railway box girder Transport Machinery, be mainly used in high speed railway or railway line for passenger traffic large scale prefabricated box beam as 900 tonnes transportation, the special bridge of concentrating of growing up that adapts to also is fit to the transportation that the case beam is striden in middle foot bridge that the bridge group disperses and change.
Background technology
The walking of beam transportation vehicle has rail-mounted and two kinds of forms of rubber-tyred.Wherein rubber-tyred is transported the beam scheme, adopt the tire traveling, and the outfit hydraulic suspension loads lotus automatic equalization system, direction autonomous cruise speed system, advantage such as therefore have when the carrying case beam that speed is fast, maneuverability, the uniform property of load are good, and the curve transportation is controlled conveniently, the job execution flow process is simple, and the temporary project amount is few.
The utility model content
The purpose of this utility model is: a kind of large-tonnage rubber-tyred beam transportation vehicle of striding the beam transportation of can realizing becoming is provided.
The purpose of this utility model realizes by implementing following technical proposals Come:
A kind of large-tonnage rubber-tyred beam transportation vehicle, by car body, girder, be arranged on the traveling wheels that drag beam chassis and girder bottom on the walking rails of girder top, steering hardware, brake system and power system, hydraulic efficiency pressure system, the electric system that is arranged on the traveling wheels formed, it is characterized in that: drag two equilibrium liquid cylinder pressures are housed on the beam chassis, form three point support case beam with two fixed pedestals of beam transportation vehicle front end load-bearing crossbeam, drag the beam chassis to link to each other by the reel of sprocket wheel and hydraulic efficiency pressure system.
Described traveling hydraulic efficiency pressure system adopts variable-dis-placement motor Closed Hydraulic Driving loop, and other hydraulic efficiency pressure system all adopts open circuit;
Four of described steering hardware employings turn to oil cylinder and connecting rod, the system of cranking arm.
Adopt large-tonnage rubber-tyred beam transportation vehicle of the present utility model, stride beam, and can pack the bridge formation machine and realize shifting between bridge by dragging the position adjustment of beam chassis to transport easily to become.Four of steering hardware employings turn to oil cylinder and connecting rod, the system of cranking arm realizes four-wheel steering.Different length of connecting rod can make each wheels that different corners is arranged, with every group of requirement that the wheels corner is different in the accommodation curve driving process.
Description of drawings
