5. The reversible foot peg as set forth in claim 1, wherein: the pedal body (3.9.3.1) and the one end of being connected of couple (3.9.4) be provided with the boss, the boss on be provided with the link that uses with couple (3.9.4) cooperation.

6. The utility model provides a long rail transport operation car which characterized in that: the reversible pedal comprises a vehicle body and lower side beam bodies (3.9.1) arranged on two sides of the vehicle body, wherein the reversible pedal of any one of claims 1 to 5 is connected between the vehicle body and the lower side beam bodies (3.9.1).

Technical Field

The invention relates to the technical field of rail transportation, in particular to a reversible pedal and a long steel rail transportation operation vehicle.

Background

In the railway line construction, the length of the used single steel rail mainly comprises 12.5m and 25m and various long steel rails spliced in advance, and the maximum length can reach 500 m. The long steel rail has the advantages of reducing the number of steel rail joints, reducing the welding amount of field construction, greatly improving the reliability of the steel rail, improving the quality of vehicles in the running process and being an important guarantee for laying seamless lines.

At present, a railway long steel rail transport vehicle mainly comprises a transport vehicle set consisting of a plurality of common flat vehicles, the weight of steel rails is not large, the bearing of each end bogie vehicle is far beyond the design capability of the bearing, waste is caused, and meanwhile, when the rail is laid, the problems of inconvenience in site construction and low efficiency exist when a winch is used, a large crane is used, or manpower is used for loading and unloading.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention aims to provide a reversible pedal and a long steel rail transport operation vehicle.

The invention is realized by the following technical scheme: the utility model provides a can overturn pedal and long rail transportation operation car, includes the fulcrum seat of setting on the automobile body, set up on the automobile body and be located the couple of fulcrum seat below, with fulcrum seat articulated extending structure and middle part and the extending structure free end articulated pedal body, the one end of the pedal body be provided with the articulated fulcrum of lower side rail body, the other end and the couple of the pedal body can be dismantled and be connected.

Further, in order to better realize the invention, the hook is hinged with the vehicle body.

Further, in order to better implement the invention, the opening on the hook faces away from the pedal body.

Further, in order to better realize the invention, the telescopic structure adopts a cylinder or a hydraulic cylinder.

Furthermore, in order to better realize the invention, a boss is arranged at one end of the pedal body connected with the hook, and a hanging ring matched with the hook is arranged on the boss.

The utility model provides a long rail transport operation car, includes the automobile body and sets up the lower side rail body in the automobile body both sides, automobile body and lower side rail body between be connected with the pedal that can overturn.

The beneficial effect that this scheme obtained is: this scheme utilization pedal is convenient for control the lower side rail body and is rotated, when the long rail of automobile body transportation, makes the lower side rail body withdraw in order to ensure the security of transportation, puts down the lower side rail body in the construction so that the construction, avoids the lower side rail body to cause the interference to the construction.
