[0002] At present, the water supply network renovation project of Tangbei Village and Xihu Village on Guanghua Highway (referred to as Tangbei Village Project) is the first pilot project to install water supply pipes in the integrated pipeline corridor of Guanghua Highway. The installation of large-diameter (over 1000mm) water supply pipes in the pipeline corridor is a new technology and there are few cases in China.

[0003] The construction of the Guanghua Highway integrated pipeline corridor does not follow the conventional installation process of installing large pipes first and then small pipes. The permanent pipe piers have been prefabricated and installed, resulting in narrow pipeline channels and limited space in the corridor. However, horizontal transportation is the key to the implementation of this type of project, so the existing technology cannot meet the transportation requirements.

[0004] Therefore, it is desired in the art to provide a transfer vehicle for transporting pipes to solve the above technical problems. Utility Model Content

[0026] To make the technical solutions and advantages of the present invention more clearly understood, exemplary embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only a portion of the embodiments of the present invention, and are not exhaustive. Furthermore, the embodiments and features of the embodiments of the present invention may be combined with each other unless there is a conflict.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figures 1 to 3 As shown, the transfer vehicle 100 for transporting pipes according to the present invention mainly includes a chassis 11, a support mechanism and a traction member. Preferably, the chassis 11 is constructed into a square structure to help improve the overall stability of the transfer vehicle 100, and a drive wheel 12 is provided on the chassis 11 to assist the transfer vehicle 100 in moving forward or backward. Preferably, the support mechanism is fixedly mounted on the chassis 11 for fixing and placing the pipe 101, thereby ensuring that the pipe 101 can complete the transportation work in the narrow water supply pipe. Preferably, the traction member is fixedly mounted on one side of the chassis 11 for the operator to use in conjunction with the drive wheel 12, thereby completely controlling the two-way traction work of the transfer vehicle 100.

[0029] Since there is mud in the pipeline corridor, the transport vehicle must meet the requirements of driving stability. Therefore, the drive wheels 12 in the present invention are provided with at least four, and the drive wheels 12 are widened as a whole, thereby reducing the impact of the drive wheels 12 slipping, so as to improve the stability of the transfer vehicle 100 used to transport pipes in the pipeline corridor.

[0030] In one embodiment, Figures 1 to 3 As shown, the traction member includes a traction rod 31 and a push-pull rod 32. Preferably, a locking pin is provided on the side wall of the chassis 11, with which the traction rod 31 can be locked, thereby facilitating the traction of the transfer vehicle 100. The push-pull rod 32 is provided at the end of the traction rod 31 away from the chassis 11 for operator use, further improving the transfer efficiency of the transfer vehicle 100 used to transport pipes.

[0031] Preferably, a brake assembly is provided on the drive wheel 12, and the brake assembly can be remotely controlled via a push-pull rod 32 to ensure precise control of the transfer vehicle 100 used to transport pipes. In addition, a reversing assembly is provided on the drive wheel 12, and the reversing assembly can be remotely controlled via a push-pull rod 32 to achieve bidirectional travel while also preventing accidents caused by operator errors.

[0032] Preferably, since the pipeline corridor is long and narrow (approximately 1.6m wide), and the length of the pipe 101 is 6m per section, this application adopts a long-arm traction type traction member, which can reduce the operating force through torque, and can also be linearly fine-tuned. The long-arm distance observation can also avoid the pipe blocking the line of sight. In addition, the entire vehicle length of the transfer vehicle 100 is 3m, the vehicle height is 0.5m, and the center of gravity of the vehicle body is sunken, which can effectively avoid the problem of the pipe 101 warping. Preferably, the pipe is D1420 steel pipe.

[0033] In the present invention, a driving motor (not shown) is provided on the driving wheel 12, and a knob-type power control switch connected to the driving motor through a cable is provided on the push-pull rod 32. Thus, the transfer vehicle 100 can be driven electrically in the pipeline corridor, so that one person can operate it.

[0034] In one embodiment, Figure 1 As shown, the traction member further includes a guide wheel 33 in direct contact with the ground, and a connecting rod disposed between the traction rod 31 and the guide wheel 33. During the transfer process, the operator can change the direction of the guide wheel 33 to fine-tune the direction of travel of the transfer vehicle 100 for transporting pipes by a certain angle, thereby making it easier to pass through the accompanying small bends in the channel.

[0035] In the present invention, the connecting rod can be installed or not according to the use requirements.

[0036] In one embodiment, Figures 1 to 3 As shown, the support mechanism includes a receiving member 21 and a pipe support 22. Preferably, the receiving member 21 is securely mounted on the base 11 to effectively bear the entire weight of the pipe 101; the pipe support 22 is securely nested in the receiving member 21 via a slide 26 (described below), clamping the pipe 101 to ensure that it remains in a stable position during transportation, further improving the transportation efficiency and quality of the transfer vehicle 100 used to transport pipes.

[0037] Preferably, the traction rod 31 is constructed as a telescopic rod or a constant-diameter rod. If the traction rod 31 is a telescopic rod, the overall length of the traction rod 31 can be extended by telescoping, thereby more easily accommodating pipes of different lengths and ensuring smooth transportation. If the traction rod 31 is a constant-diameter rod, it can ensure good traction during transportation, thereby improving the transportation efficiency of the transfer vehicle 100 used to transport pipes in narrow water supply pipes.

[0038] In the present invention, multiple pipe supports 22 are provided, and the multiple pipe supports 22 are arranged in parallel on both sides of the receiving member 21. In this way, the pipe supports 22 can effectively improve the limiting ability of the pipe 101, thereby ensuring the stability of the pipe 101 during the transfer process, and further improving the transfer efficiency and transfer quality of the transfer vehicle 100 used for transporting pipes.

[0039] Preferably, the receiving member 21 is constructed in a frame-like form, and the multiple pipe supports 22 can be arranged symmetrically or staggered on the receiving member 21. Therefore, in this way, the points of support of the pipe 101 can be effectively dispersed, thereby improving the support capacity of the pipe 101 and ensuring the integrity of the pipe 101 during transportation.

[0040] In one embodiment, Figure 2 As shown, the pipe holder 22 includes a main body 221 configured in a plate-like form, and a stopper portion disposed on the main body 221 and configured to abut against the pipe 101. Preferably, a guide slope 223 is formed at the junction of the stopper portion and the pipe 101. Thus, the pipe 101 is fully engaged within the adjacent pipe holder 22 under the action of the guide slope 223, further ensuring the stability of the pipe 101 during transportation.

[0041] Preferably, a plurality of staggered wear-resistant protrusions (not shown in the drawings) are provided on the guide slope 223. This effectively increases the friction between the pipe 101 and the pipe support 22, so that the axial position of the pipe 101 remains unchanged during transportation, thereby improving the transfer efficiency and speed of the transfer vehicle 100 used to transport pipes.

[0042] In one embodiment, Figure 3 As shown, the support mechanism also includes two crossbeams 23 symmetrically arranged within the receiving member 21. Preferably, a chute 26 is formed between the crossbeam 23 and the receiving member 21, and an adjustment portion (not shown in the drawings) is provided below the main body 221, which can be nested within the chute 26. Furthermore, the pipe support 22 can move laterally within the chute 26, thereby adjusting its position within the receiving member 21 and thereby adjusting the stress point of the pipe 101 to ensure that it can meet the requirements of long-term transportation.

[0043] Preferably, a friction surface is formed on the side wall of the adjustment portion, so that after the pipe support 22 is nested in the slide groove 26, it generates a large friction force with the receiving plate 21 and the crossbeam 23 respectively, so as to limit the position of the pipe support 22 to a certain extent, thereby avoiding the phenomenon of dislocation of the pipe support 22 during transportation.

[0044] In one embodiment, a plurality of spaced-apart stoppers 24 are provided within the chute 26. Preferably, the stoppers 24 can effectively limit the movement path of the pipe supports 22, thereby effectively dividing the area where each pipe support 22 is located, further ensuring that each support point of the pipe 101 is secure, thereby improving the support capacity of the pipe 101 and ensuring the integrity of the pipe 101 during transportation.

[0045] Preferably, a plurality of reinforcing ribs 25 are arranged in a staggered manner in the transverse or longitudinal direction between the two cross beams 23. In this way, the overall rigidity of the receiving member 21 can be effectively improved to meet the requirements of supporting the pipe 101, further improving the transfer efficiency and speed of the transfer vehicle 100 used for transporting pipes.

[0046] Preferably, the device adopts an electrical power supply, and the power supply line is wrapped with an insulating sleeve to prevent people from electric shock. It can supply power for a long time, saving battery replacement time and avoiding battery aging problems compared with battery power supply.

[0048] The present invention adopts a long-arm traction method, that is, a locking pin is provided on the side wall of the chassis 11, and the traction rod 31 can be locked with the locking pin, so that the transportation of the pipe 101 can be completed by the traction rod 31 and the push-pull rod 32, thereby coping with the problem that the pipeline corridor path is long and narrow. Preferably, this method has the advantages of reducing the operating force through torque, linear fine-tuning, and long-arm distance observation can also avoid the pipe blocking the line of sight. In addition, the present invention also changes the direction of the guide wheel 33 to fine-tune the travel direction of the transfer vehicle 100 used to transport the pipes to a certain angle, so that it can more easily pass through the accompanying small bends in the channel.
