Problems solved by technology

[0002] In the manufacturing and installation of water conservancy and hydropower steel pipes, steel pipes are usually welded into a section within 6m, transported to the installation site by car, special trailer or rail trolley, and then installed, welded and anti-corrosion. When the diameter of the steel pipe is large , such as the diameter of more than 9m, the transportation and installation of steel pipes are very difficult, especially for the installation of large-diameter steel pipes in tunnels. At present, there is no very effective equipment for construction at home and abroad. Some steel pipe projects adopt the method of assembling and welding the rolled tiles on the platform at the installation site to form steel pipe sections, and then use the rail trolley to transport the steel pipe sections to the installation site, and finally complete the welding and anticorrosion of the steel pipes. However, due to Scattered sites and existing equipment have simple functions, low degree of construction mechanization, and difficulty in turning over large-diameter steel pipes, resulting in poor transportation safety of steel pipes, high labor intensity, and low production efficiency
The tunnel transport trolley disclosed in Chinese patent 02110317.8 can only be used for the transportation and installation of PCCP pipelines with small and medium diameters. Japanese patent No. Kaiping 9-315299 discloses a mobile installation trolley for pipelines, which is suitable for transportation and installation of pipelines with larger diameters , but because its structure occupies a large space and its functions are simple, its role in transporting and installing pipelines in relatively small tunnels is limited

Embodiment Construction

[0020] like figure 1 , 3 As shown, the front and rear ends of the main beam 1 of the steel pipe trolley are respectively equipped with outriggers 1 and outriggers 3. The contraction of the outriggers 1 and outriggers 3 is controlled by the hydraulic pump station 4, and the longitudinal walking is installed on the horizontal track of the main beam 1. Frame 5 and winch 6, through the effect of hoist 6, steering wheel 7 and steel rope, longitudinal traveling frame 5 may reciprocate on the horizontal track of main girder 1, and rotating frame 8 is mounted on longitudinal traveling frame 5 through the hole shaft. A gear drive mechanism is used to rotate the rotating frame 8 on the longitudinal walking frame 5, and 24 adjusting supports 9 are installed on the placing frame 8. The adjusting supports 9 are composed of a hydraulic jack 10 and a screw jack 11, which can be disassembled, and the sides of the adjustable supports 9 Carry out pre-tensioning with drag cable 12. In the abov...
