[0002] The subway is a fast, high-capacity, electric-powered rail transit system built in the city. The trains run on fully enclosed lines. The lines in the central urban area are basically located in underground tunnels, and the lines outside the central urban area are generally located on viaducts or on the ground. The subway is a high-density, high-capacity urban rail transit system that covers all kinds of underground and above-ground road rights in urban areas. During the construction of the subway, the subway tracks are usually transported to the vicinity of the installation site, and then manually transported to the installation site for installation. This results in a large number of personnel, high labor costs, and slow and inefficient manual transportation, which also affects the progress of subway construction.

However, the prior art has limitations in use. The length of subway rails transported by the subway construction handling devices in the prior art is relatively short. When a longer subway rail needs to be transported, a single hoist is not stable enough during the transport process, and the length of a single subway rail transporting plate is also limited.

The frame 5 is an n-shaped or trapezoidal structure. In this embodiment, the frame 5 is a trapezoidal structure and the bottoms of both ends of the frame 5 are fixed to the front and rear ends of the top surface of the transport platform 3. The lifting track 6 is fixed to the bottom surface of the top of the frame 5, and the lifting track 6 is perpendicular to the moving direction of the transport device. A crossbeam 9 is arranged on the top surface of the frame 5, and the crossbeam 9 is located directly above the lifting track 6. A plurality of connecting beams 10 are fixedly connected between the crossbeam 9 and the lifting track 6, and the plurality of connecting beams 10 are arranged at equal intervals.

[0027] Specifically, in this embodiment, the interface of the lifting track 6 is an "I"-shaped structure, and limit plates are fixed at both ends of the lifting track 6 to prevent the lifting mechanism 7 from escaping. A group of lifting mechanisms 7 are arranged on the lifting track 6, and the lifting mechanism 7 is specifically a traveling electric hoist. The end of the lifting rope of the traveling electric hoist is connected to the track clamp 8, so that the traveling electric hoist can drive the track clamp 8 to move along the lifting track 6, thereby loading and unloading the subway tracks 4 on both sides of the frame 5.
