[0026] As Figures 1-6 shown, Embodiment 1 of the present invention provides a mobile transportation device for the installation and transportation of large-diameter pipelines 3. The mobile transportation device includes several groups of sliding structures 1 and a traction structure 2 that cooperates with the several groups of sliding devices.

The roller shaft 12 is located between the two groups of roller brackets 13 and is hinged to them. The roller sleeve 11 is fixed on the outer surface of the roller shaft 12. A large-diameter pipeline 3 is placed above the roller sleeve 11 of the roller shaft 12. Specifically, each group of sliding structures 1 includes two limit rods 14. The two limit rods 14 are respectively fixed on the outer sides of the two groups of roller brackets 13. Both of the two limit rods 14 are made of angle steel or channel steel and are fixed at both ends of the roller shaft 12 by welding according to the diameter of the large-diameter pipeline 3 to displace the pipeline in a specified direction. The traction structure 2 includes a hoisting gourd 21, a fixing belt 22, and a fixing seat 23. The fixing belts 22 are respectively tied to both ends of the large-diameter pipeline 3. One end of the hoisting gourd 21 is fixed on the fixing seat 23, and the other end of the hoisting gourd 21 hooks the fixing belt 22 tied to the large-diameter pipeline 3. In the present invention, the large-diameter pipeline 3 is placed above the roller sleeve 11 of the roller shaft 12, and the large-diameter pipeline 3 on the sliding structure 1 is towed through the traction structure 2. The several groups of sliding structures 1 provided in the present invention are mainly used in the electromechanical systems of large-diameter and long pipelines, and can cooperate with the traction structure 2 for hoisting to realize the random movement of the large-diameter pipeline 3 above the roller shaft 12 to the required position, which is convenient for the installation of the large-diameter pipeline 3. By setting the two limit rods 14, it is mainly to prevent the large-diameter pipeline 3 from deviating outside the roller shaft 12 during the sliding process, which can play a limiting role in the transportation of the large-diameter pipeline 3 and prevent the large-diameter pipeline 3 from deviating during the transportation process.

[0027] Specifically, the hoisting gourd 21 of the present invention includes a hoisting chain block 211, a sprocket 212, and a hook 213. One end of the hoisting chain block 211 is connected to the sprocket 212, and the other end of the hoisting chain block 211 is connected to the hook 213. The sprocket 212 is installed on the fixing seat 23, and the hoisting gourd 21 hooks the fixing belt 22 tied to the large-diameter pipeline 3 through the hook 213.

[0028] Each set of sliding structures 1 includes a bottom plate 15 , which is installed at the bottom of two sets of limiting rods 14 and two sets of roller brackets 13 . The bottom plate 15 supports and fixes the two sets of limiting rods 14 and the two sets of roller brackets 13 .

[0029] The roller shaft 12 of the utility model is a galvanized steel pipe, which is mainly used to support and drive an important part of the transport steel pipe and is an important component of the pulley.

[0030] The upper parts of the two groups of roller brackets 13 are connected to the roller shaft 12, and the bottom ends of the two groups of roller brackets 13 are fixed to the base plate 15 by welding. In specific implementation, a slot is provided on the upper part of each group of roller brackets 13, and the roller shaft 12 is installed and connected through the slot on the upper parts of the two groups of roller brackets 13, and the components of the roller shaft 12 are supported by the two groups of roller brackets 13.

[0031] The specific installation process of the mobile transport device of the utility model is as follows:

[0032] Step 1) Installation of the bottom plate 15 and the limiting rods 14: According to the transportation path of the large-diameter pipeline 3, use the wire releaser to accurately locate the position of the bottom plate 15, connect and fix it with the fixed point through expansion bolts, and weld two sets of limiting rods 14 on both sides above the bottom plate 15 according to the diameter of the large-diameter pipeline 3 to prevent the pipeline from shifting during transportation;

[0033] Step 2) Installation of the roller shaft 12: In the middle of the limit rod 14 fixed in step 1) and above the bottom plate 15, weld the bottoms of the two sets of roller brackets 13 to the bottom plate 15, and then install the two ends of the roller shaft 12 to the slots on the upper parts of the two sets of roller brackets 13;

[0034] Step 3) Installation of the hoisting hoist 21: At the front end of the transportation path of the large-diameter pipeline 3, above the roller shaft 12, the sprocket 212 of the hoisting hoist 21 is installed on the beam 4 of the building through the fixing seat 23 to facilitate the transportation of the pipeline after it is in place;

[0035] Step 4) Hoisting the large-diameter pipe 3 into place: According to the weight of the large-diameter pipe 3, select a suitable crane to lift the pipe. During lifting, in order to prevent the pipe from tilting, the lifting points need to be selected at both ends of the large-diameter pipe 3, and then slowly and steadily place the large-diameter pipe 3 on the roller sleeve 11 of the roller shaft 12;

[0036] Step 5) Hoist the pipe with a chain block: After the pipe is in place steadily, remove the sling, tie the fixing band 22 to both ends of the large-diameter pipe 3, hook the hook 213 at the end of the hoisting chain 211 of the hoisting chain block 21 to the fixing band 22 of the large-diameter pipe 3. Through the action of the roller shaft 12, the hoisting chain 211 can be pulled manually, and the slow transportation of the large-diameter pipe 3 above the roller shaft 12 can be easily achieved, which is very convenient for moving and transporting the large-diameter pipe 3 to the specified installation position.

Through the cooperation of the traction structure 2 and several groups of sliding structures 1, the large-diameter pipe 3 can be moved easily and efficiently, greatly improving the working efficiency of moving the large-diameter pipe 3. By cooperating the sliding structure 1 and the traction structure 2 to transport the large-diameter pipe 3, safety accidents such as falling and collision that may be caused by manually handling the large-diameter pipe 3 can be avoided, greatly improving the safety of the workplace. The mobile transportation device provided by the present invention facilitates the installation of the large-diameter pipe 3, can significantly reduce the labor required for manually handling and moving the large-diameter pipe 3, reduce the labor intensity of workers, and at the same time reduce handling errors and damages caused by human factors, and is particularly suitable for the installation of large-diameter pipes 3 in air-conditioning machine rooms and utility tunnels.
