[0029] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent, easy to understand, the specific embodiments of the utility model are described in detail below with reference to the drawings of the specification.

[0030] In the following description, many specific details are set forth in order to provide a thorough understanding of the utility model, but the utility model can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0031] Secondly, the "one embodiment" or "embodiment" referred to here means that the specific features, structures or characteristics can be included in at least one implementation of the utility model. "In one embodiment" does not mean the same embodiment in different places in this specification, nor is it an independent or alternative embodiment that excludes other embodiments. The utility model provides the following embodiments.

[0032] Reference Figure 1 and Figure 2 For the transport equipment structure diagram for large-diameter PCCP pipes in this embodiment, the transport equipment of this embodiment includes a transport frame 100, a plurality of wheels 1033 are installed at the bottom of the transport frame 100, a plurality of pipe frames 200 are assembled on the upper surface of the transport frame 100, the large-diameter PCCP pipes are carried by the pipe frames 200 in this embodiment, the pipe frames 200 play a role in restraining the pipes, and the pipes are moved to realize the transport by the transport frame 100.

[0033] Referring to Figure 6 In the embodiment, the pipe rack 200 is composed of a pair of symmetrical square tubes 201 and symmetrical steel columns 202 welded on the upper surface of the square tubes 201, and the upper ends of the steel columns 202 on the same side are jointly welded with a connecting beam 203, and a plurality of roller barrels 204 are uniformly arranged on the connecting beam 203. In the embodiment, the square tube 201, the steel column 202 and the connecting beam 203 make the pipe rack 200 a steel structure, which has high strength and stability and can bear the weight of the large-diameter PCCP pipe to ensure the safety of the pipe during the transfer. The large-diameter PCCP pipe is placed on the roller barrels 204 of the pipe rack 200 by the tower crane and is transferred by the transport frame 100. Further, the roller barrel 204 in the embodiment is composed of a plurality of roller shafts, and the two ends of the roller shaft are connected with a pin piece. The plurality of roller shafts are pin-connected by the pin pieces to form the roller barrel 204. The roller barrel 204 forms a concave structure in the pipe rack 200 and is used to place the large-diameter PCCP pipe. This design can reduce the friction and wear of the pipe during the transfer and protect the surface of the pipe from damage. Further, the roller barrel 204 is composed of a plurality of roller shafts, and the roller shafts are pin-connected by the connecting pieces. The roller barrel 204 can adapt to different pipe diameters and shapes during the transfer because the connecting pieces can allow a certain deformation between the roller shafts, so as to better fit the surface of the pipe. At the same time, the pin connection design formed by the connecting pieces makes it relatively easy to replace or maintain the roller shaft. The damaged parts can be individually disassembled and replaced without replacing the entire roller barrel 204.

[0034] Referring to Figure 6 and Figure 7 In the embodiment, a plurality of connecting ears 2031 are equidistantly welded on the upper surface of the connecting beam 203, the connecting ears 2031 are formed by bending steel bars, and the pin pieces on the outermost roller shafts of the roller barrel 204 are connected with hooks 2041, which are hung on the connecting ears 2031. In the embodiment, the roller barrel 204 is hung on the pipe rack 200 by the hooks 2041. The number of the roller barrels 204 is increased or decreased according to the length of the large-diameter PCCP pipe, so that the same set of equipment can be applied to the transportation of pipes of different specifications, improving the versatility and flexibility of the equipment. By increasing or decreasing the number of the roller barrels 204, the support demand of pipes of different lengths can be better met, the deformation and stress concentration of the pipes during the transportation are reduced, and the integrity of the pipes is protected. When transporting pipes of different lengths, the entire transport equipment does not need to be replaced, but only the number of the roller barrels 204 needs to be adjusted, saving time and labor costs and improving work efficiency. The adaptability is provided.

[0035] It is worth noting that the connecting lug 2031 in the embodiment is in a W-shaped structure, and the lengths of the two outer bending points of the connecting lug 2031 are different. Firstly, the W-shaped structure can provide more contact points and support surfaces, so that the connection is more stable. The different lengths of the outer bending points can adapt to different stress conditions, increase the stability of the connection, make the stress distribution more uniform, reduce local stress concentration, thereby improve the reliability and durability of the connection. At the same time, the different lengths of the outer bending points can adapt to different sizes and shapes of hooks, thereby increasing the versatility and adaptability of the connecting lug 2031.

[0036] Referring to Figure 6 In order to increase the stability of the pipe rack 200, the embodiment is welded with an angle steel 2021 on the outside of the same side steel column 202, and the outside of the steel column 202 is also welded with a rope hook. When the large-diameter PCCP pipe is placed on the pipe rack 200, a safety rope is bound. The safety rope is fixed and constrained on the large-diameter PCCP pipe by winding on the rope hook, thereby improving the safety.

[0037] Referring to Figure 4 The lower surface of the transport rack 100 is integrally connected with a beam 101 at the center, so that the strength of the transport rack 100 is further improved, and the transport of the large-diameter PCCP pipe can be completely satisfied. The two ends of the beam 101 are both equipped with a traction head 104. The transport rack 100 is connected with a traction vehicle through the traction head 104 to transport the large-diameter PCCP pipe placed on the pipe rack 200. Figure 2 A plurality of crosspieces 102 are equidistantly arranged on both sides of the beam 101, so that the integrity of the beam 101 and the transport rack 100 is better, and the force is dispersed to a certain extent, the concentrated stress is eliminated, and the upper surface of the crosspiece 102 is welded with the lower surface of the transport rack 100. The lower surface of the transport rack 100 and located between adjacent crosspieces 102 is provided with a turntable 103. The lower surface of the turntable 103 is equipped with a wheel frame 1032, and the wheel frame 1032 is installed with wheels 1033 on both sides of the lower end. In the embodiment, the wheels 1033 at the lower end of the wheel frame 1032 move in the line of sight. A plurality of independent wheel frames 1032 can share the weight, and the weight of the entire device and pipeline is evenly conducted to the ground.

[0038] Referring to Fig. 5, the side of the rotating disc 103 is provided with a connecting piece, and the rotating disc 103 is rotationally connected with the telescopic rod 1031 through the connecting piece. The end of the telescopic rod 1031 is hingedly connected with the pin seat 10311, and the pin seat 10311 is fixed on the crosspiece 102. In this embodiment, the wheel 1033 adopts the telescopic rod 1031 to steer, so that the transport frame 100 has better flexibility and maneuverability during the transfer process, can adapt to different working environments and transport routes, and the upper surface of the transport frame 100 and located directly above the telescopic rod 1031 is provided with an inspection opening, which is convenient for maintenance personnel to maintain the telescopic rod 1031 from the top of the transport frame 100, without entering the bottom of the transport frame 100, thereby reducing the danger.

For ordinary skilled in the art to which the present application belongs, without departing from the concept of the present application, a number of simple deductions or substitutions can be made, which should be considered as belonging to the protection scope determined by the claims of the present application.
