[0002] Pipeline laying is often a large project with long laying distances. In secondary water supply projects, such as high-rise water supply, secondary water supply is often involved. Although the laying distance is not too far, the number of pipes required is also large. During construction, multiple groups of pipes are often placed near each secondary water supply point and along the laying route in advance. Each group of pipes includes multiple pipes, which are placed near a laying location. Later, according to the specific laying location of each pipe, the construction personnel will move the pipe to the specific laying location of the pipe. For large-diameter and heavy-weight pipes, manual handling is time-consuming and labor-intensive, and sometimes even sprains, stretches, and injuries may occur during the handling and movement process.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] As shown in the figure, a transport device for pipeline transportation in a secondary water supply project includes a connecting beam 1 and a supporting beam 3. Both connecting beams 1 are U-shaped steel structures, and the U-shaped grooves 11 of the two connecting beams 1 are arranged opposite to each other. A slide rail 2 is fixedly connected to the inner wall of the bottom side of the U-shaped groove 11 of the two connecting beams 1. A plurality of supporting beams 3 are arranged side by side between the two connecting beams 1. Both ends of the bottom side of each supporting beam 3 are provided with pulleys 4. The supporting beam 3 can be slidably connected to the slide rail 2 through the pulleys 4. A plurality of universal wheels 6 with braking functions are provided on the bottom side of each connecting beam 1. In this embodiment, the slide rail 2 is welded to the bottom wall of the U-shaped groove 11 of the connecting beam 1. When in use, the position of the support beam 3 on the slide rail 2 and the interval between multiple support beams 3 are adjusted according to the actual operation conditions at the construction site, so as to save effort and be more convenient when placing the pipeline 10; two carrying devices are used to hold up the two ends of the pipeline 10, and when the operator moves the carrying device, the support beam 3 is compressed under the action of the pipeline 10's own gravity so that it moves forward with the connecting beam 1; using this device, the operator only needs to lift the pipeline 10 to a lower height and place it on the support beam 3, which greatly reduces the safety risks that may occur when the operator is carrying it.

[0024] A bottom beam 5 is fixedly connected to the bottom side of each connecting beam 1, and the bottom beam 5 is a square steel structure, and universal wheels 6 are arranged at both ends of the bottom side of the bottom beam 5. In this embodiment, the connecting beam 1 is welded to the upper side of the bottom beam 5, and square steel is used as the bottom beam 5. On the one hand, it saves steel while ensuring the support strength, and on the other hand, it is used to raise the connecting beam 1 to prevent the support beam 3 from dragging on the ground.

[0025] A plurality of reinforcing beams 8 are fixedly connected between the two bottom beams 5, and the bottom side of the reinforcing beams 8 is higher than the bottom side of the bottom beams 5, so as to prevent the reinforcing beams 8 from being blocked by the protrusions of the ground when moving on the uneven ground. In this embodiment, the reinforcing beams 8 are also square steel structures, and the connection strength between the two bottom beams 5 is enhanced by the reinforcing beams 8.

[0026] The middle of the support beam 3 is a downwardly concave arc section 31, and the two ends are horizontal sections 32 located at the two ends of the arc section 31. The pulley 4 is installed on the bottom side of the corresponding horizontal section 32. The limit strip 14 is fixedly connected to the inner wall of the upper side of the U-shaped groove 11 of the connecting beam 1 along the length direction of the slide rail 2. A through groove 33 with an opening upward is opened at the upper side of the horizontal section 32 of each support beam 3 corresponding to the limit strip 14, and the limit strip 14 is arranged through the through groove 33. In this embodiment, the arc section 31 and the horizontal section 32 of the support beam 3 are an integrally formed structure, and the limit strip 14 is welded in the U-shaped groove 11 of the connecting beam 1. Through the cooperation of the limit strip 14 and the through groove 33, the support beam 3 is limited and guided to prevent one end of the support beam 3 from tilting off the slide rail 2 due to unbalanced force.

[0027] The rear end of the connecting beam 1 extends out of the rear end of the bottom beam 5 to form an extension 12, and a connecting hole 13 penetrating the extension 12 is vertically opened on the upper side wall corresponding to the extension 12, and a T-shaped baffle 9 is inserted between the connecting holes 13 of each extension 12, and the top of the baffle 9 is located on the upper side of the extension 12, and the lower end passes through the connecting hole 13 and extends to the middle of the bottom beam 5 to prevent the baffle 9 from jumping out of the connecting hole 13 when bumps occur. In this embodiment, the baffle 9 is set to prevent the support beam 3 from detaching from the connecting beam 1 when moving along the slide rail 2, and the baffle 9 is set to a plug-in structure, which is convenient for operators to disassemble and install the baffle 9, and then convenient for replacing the connecting beam 1.

[0028] A handrail frame 7 is fixedly connected to one end of the two connecting beams 1, and the handrail frame 7 includes vertical sections on both sides and a U-shaped middle section located between the tops of the two vertical sections. The middle section is arranged outwardly from bottom to top, and the middle section and the vertical section are an integrally formed structure or are welded and fixed together. In this embodiment, a reinforcing rod is welded between the middle parts of the two vertical sections, and the vertical section of the handrail frame 7 is welded to the connecting beam 1 and one end of the bottom beam 5.

[0029] The working process of this embodiment is as follows:

[0030] When in use, two carriers are placed opposite to each other and located near the two ends of a section of pipe 10, so that the handrails 7 are both located outside the pipe 10. The pipe 10 is manually lifted and the two ends of the pipe 10 are placed on the support beams 3 of the two carriers. When the handrails 7 are manually pushed and pulled, the support beams 3 move together with the connecting beams 1 under the pressure of the pipe 10. When the pipe 10 needs to be unloaded, the pipe 10 is manually slightly lifted and the carrier is moved out of the bottom of the pipe 10. The device is suitable for transporting large and heavy pipes 10 over short distances.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
