Abstract
The invention provides a double-shaft eight-wheel floated loading vehicle for a roadway acceleration loading test, which belongs to the field of test equipment. The double-shaft eight-wheel floated loading vehicle for a roadway acceleration loading test is characterized in that a front rotating shaft and a rear rotating shaft are arranged on the loading vehicle; both two loading steel wheels and two return steel wheels are assembled on each rotating shaft, and the return steel wheels can freely rotate around the rotating shafts. In the repeated rolling test process of the loading vehicle of the roadway acceleration loading test device on the roadway, the loading vehicle reliably realizes the processes of loading roll and unloading return, thereby more favorably solving the problems of special loading orbit curve and unequal distance of a return orbit in the running of the four-shaft eight-wheel floating mechanism loading vehicle, simplifying the structure and the process of the loading vehicle and improving the safety and the reliability of the whole roadway acceleration loading test device.
Description
(1) technical field
The present invention relates to a kind of unsteady car that loads of double-shaft eight-wheel that is used for road surface accelerating and loading experimental, belong to the experimental facilities field.
(2) background technology
Road surface accelerating and loading experimental device is the special equipment of test ground surface material and structure.The loading steel wheel of existing road surface accelerating and loading experimental device loads car is fixed in the different rotating shafts with the backhaul steel wheel; Complex structure; The problem of bringing be load the orbital curve form special and with return track equidistance not, the security and stability of device is not high, and processing and assembling is complicated; Be not easy to maintenance, be difficult to reach technical requirements.
(3) summary of the invention
Technical assignment of the present invention is the deficiency to existing road surface accelerating and loading experimental equipment; Provide a kind of and can improve security of system, load bassinet structure reliably; The security and stability of raising system; Simplify technology for processing and assembling, reduce cost, improved the safety and the reliability of road surface accelerating and loading experimental device.
The technical solution adopted for the present invention to solve the technical problems is: load car and be provided with two rotating shafts in front and back, all be equipped with two in each root rotating shaft and load steel wheels and two backhaul steel wheels, the backhaul steel wheel can freely rotate around the shaft.In addition, roll process in loading, said loading steel wheel moves on the loading track, and in unloading backhaul process, said backhaul steel wheel moves on return track.
A kind of double-shaft eight-wheel that is used for road surface accelerating and loading experimental of the present invention floats and loads car compared with prior art; The beneficial effect that is produced is: adopt this structure to load car; Can solve effectively former four eight take turns relocation mechanism load car loading orbital curve in service special and with the return track problem of equidistance not; Simplify the structure, the processing and assembling that load car, improved the safety and the reliability of whole road surface accelerating and loading experimental device.

Among the figure, 1, return track, 2, the backhaul steel wheel, 3, load steel wheel, 4, load track, 5, rotating shaft.
Fig. 3, Fig. 4 take turns relocation mechanism loading car owner view, left view for former four eight.
(5) specific embodiment
In conjunction with Fig. 1, Fig. 2 to a kind of double-shaft eight-wheel that is used for road surface accelerating and loading experimental of the present invention float load car do below explanation at length.
Like Fig. 1, shown in Figure 2, a kind of double-shaft eight-wheel that is used for road surface accelerating and loading experimental of the present invention floats and loads its structure of car and comprise---and 1, return track, 2, the backhaul steel wheel, 3, load steel wheel, 4, load track, 5, rotating shaft.
The unsteady car that loads of the double-shaft eight-wheel of above-mentioned road surface accelerating and loading experimental loads car and is provided with two rotating shafts in front and back, two backhaul steel wheels 2 of assembling and two loading steel wheels 3 in each root rotating shaft 5, and backhaul steel wheel 2 can 5 freely rotate around the shaft.Roll process in loading, load steel wheel 3 and loading operation on the track 4, in unloading backhaul process, backhaul steel wheel 2 moves on return track 1.
Except that the described technical characterictic of manual, be the known technology of those skilled in the art.
Claims (2)
