[0002] Pipeline transportation tools are mainly used for transporting pipelines in the combined yard of thermal power plants and outside the coverage area of overhead traveling cranes in the plant, especially for transporting pipelines in small spaces or narrow areas. At present, gantry cranes are mostly used to transport pipelines in the pipeline combined yard of thermal power plants. However, the on-site mechanical use is tense. For pipelines with a small number of single transports, high frequency, and light weight, the mechanical cost of using a gantry crane for transportation is high, and long-term transportation is not conducive to cost savings. When transporting pipelines within the plant area, heavy pipelines are often towed by manual hoists using temporary lifting points, lighter ones are transported by rolling bars or in cooperation with 2 manual hydraulic forklifts, and even lighter ones are carried by two or four people or directly rolled to the construction site for installation construction. These transportation methods are likely to cause scratches on the pipelines and serious damage to the ground, and there are also relatively large safety hazards. Especially during manual transportation, once the pipeline cannot be lifted or slips, there is a risk of hand or foot injury when directly grasping the pipe orifice with the hand or carrying the pipeline on the shoulder.

[0030] During the operation principle or structural principle, when transporting a pipeline, the tool is moved above the pipeline by pushing, and the position of the support gantry 2 is adjusted so that the support gantry 2 is located in the middle of the pipeline. Then, the binding belt is passed through the lower parts of both ends of the pipeline and one end of the binding belt is supported and fixed by the lifting arm 13. Then, the other end of the binding belt is wound and installed on the upper part of the lifting hinge column 14. The lifting hinge column 14 is rotationally driven by a wrench tool. By using the lifting traction of the binding belt, the overall lifting of the pipeline is completed. After completion, the lifted pipeline is tied and fixed by the binding belt, and the binding belt is supported and connected by the binding belt mounting seat 4. Then, the adjusting turntable 8 is shaken, and the driving worm 9 and the driving worm gear 10 are used to cooperate and drive the double-headed lead screw 7 to rotate. Driven by the double-headed lead screw 7, the two limit clamp seats 6 move synchronously towards each other, and the middle part of the pipeline is clamped and supported by side clamping. Then, the adjusting turntable 8 is locked and limited by screwing the fastening base 12. After completion, the device is pushed and moved by the push-pull handrails 18 at both ends of the lifting bracket 1 to move the pipeline to the construction area. After the pipeline is moved, the limit clamp seats 6 are first expanded and reset. Then, the binding belt on the upper part of the binding belt mounting seat 4 is first removed. Then, the pipeline is slowly lowered by the lifting hinge column 14. After completion, the binding belt on the upper part of the lifting hinge column 14 is removed to complete the transportation work of the pipeline.

The structure is simple, flexible and light to use, which can reduce the labor intensity of the operator to the greatest extent, reduce labor costs, and ensure safety. A limited clamp seat 6 is arranged in the middle of the supporting door frame 2, and the limited clamp seat 6 is driven by a double-headed screw rod 7. During the pipeline transportation process, the middle part of the pipeline can be clamped and fixed, so that the pipeline will not slip due to bumps during transportation. The lifting bracket 1 is suitable for pipeline transportation in power plant combination yards and factory buildings where vehicles cannot cover the area, as well as in various scenarios where the site is small and it is not convenient for flatbed trucks to enter and exit. In particular, it can be used for short-distance multiple round trips to transport the pipeline while also ensuring that the pipeline is not worn during transportation. A lifting hinge column 14 and a lifting arm 13 are provided at both ends of the lifting bracket 1.
