[0042] Example 2

[0043] like Figure 4 As shown, this embodiment provides a transportation method using a prefabricated pipe transport device, specifically:

[0044] 1) Prepare for transportation operations;

[0045] Preparations must be made before transporting prefabricated pipes. Pre-transport preparations include: Prefabricated pipe inspection: All prefabricated pipes to be transported must be inspected to ensure they meet quality requirements and are free of defects such as damage and cracks. The dimensions, weight, and other parameters of the prefabricated pipes must also be checked to ensure they are in compliance with the transportation plan. Vehicle inspection: Check the crane's performance, including the integrity of key components such as the boom, hook, and wire rope. Ensure the transport vehicle's load capacity meets the prefabricated pipe's weight requirements and that the vehicle is in good condition. Transport route planning: Select a suitable transport route based on the prefabricated pipe's size, weight, and transport distance. Ensure the route is flat, solid, and free of potholes or other unfavorable factors. If crossing a road is necessary, assess traffic conditions along the route to avoid peak hours or congested sections. Safety measures: Develop detailed safety operating procedures, covering all aspects of lifting, transport, and unloading. Ensure operators hold relevant operating certificates and receive professional training. Prepare necessary emergency tools and materials to handle potential emergencies. Operators must wear helmets and gloves to ensure personal safety.

[0046] Lifting and transporting prefabricated pipes; hoisting and transporting operations include selecting appropriate lifting points according to the weight and size of the prefabricated pipes, and then hoisting and transporting them through transportation devices; hoisting and transporting operations include selecting appropriate lifting points according to the weight and size of the prefabricated pipes, and then hoisting and transporting them through transportation devices;

[0047] When assembling the transport device, first install the travel steering mechanism 6 on the bottom of the second telescopic assembly 11 through the rotating shaft 5, and install the lifting winch 9 on the first telescopic assembly 10. The first telescopic assembly 10 and the second telescopic assembly 11 are connected by the frame lifting electric cylinder to realize the up and down movement of the first telescopic assembly 10. At the same time, the first telescopic assembly 10 can realize the sliding extension and retraction of the integrated frame through the electric cylinder on the transport device. The length of the frame is adjusted by the electric cylinder on the transport device, and the height of the first telescopic assembly 10 is adjusted by the frame lifting electric cylinder. Then, the prefabricated pipes are hoisted by four independent lifting winches 9. During the lifting process, pay attention to the state of the balance bar of the prefabricated pipes and the stability of the lifting winch 9.

[0048] 3) Unloading and stacking management;

[0049] After arriving at the unloading position, the unloading operation is carried out and stacking management is carried out; specifically, after lifting into place, the movement of the transport device is controlled by the walking and steering mechanism 6 to transport the prefabricated pipes to the lifting point.

After unloading, the prefabricated pipes are firmly fixed on the transport vehicle to avoid displacement or tipping during transportation. The prefabricated pipes are fixed with suitable fixing devices to ensure stability during transportation.

[0050] 4) Equipment maintenance;

[0051] After the transportation operation is completed, the vehicles and other equipment should be maintained; after the transportation equipment is used, its various parts should be maintained to ensure the performance of the equipment is good and provide a certain degree of safety for the next operation.

[0052] The advantage of the present invention is that when the present invention is in use, the frame is used for overall arrangement, and the telescopic components on the transport device adjust the length of the frame, and the height of the frame is adjusted by the telescopic components. The structure is simple, the volume is small and the movement is flexible. The walking and steering mechanism 6 can drive the tires to realize walking movements, and is driven by the rotary reducer 16, and has forward, backward, oblique, horizontal, and on-the-spot steering and other movements, which effectively avoids the problem of affecting road traffic when in use; four independent lifting winches 9 are used to lift the prefabricated pipes, and after lifting into place, the movement of the transport device is controlled by the walking and steering mechanism 6 to transport the prefabricated pipes to the lifting point. The equipment design comprehensively considers the equipment size and the convenience of personnel operation, simplifies the operation process while ensuring safety, and is convenient and quick to operate. At the same time, the transport device adopts an integrated design of lifting, transportation and loading to effectively improve transportation efficiency; the structure is simple and the later maintenance is convenient. While ensuring comprehensive functions, the equipment cost is effectively reduced. At the same time, the equipment is provided with sound and light alarms, mechanical self-locking, etc., which ensure the stability and safety of the operation process.
