Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0037] Currently, pipeline laying requires welding multiple sections of metal pipes on the inner wall of precast concrete pipes. When transporting metal pipes into precast concrete pipes, the transportation efficiency of the metal pipes is greatly affected due to space limitations. Moreover, after the metal pipes are transported to the right place, it is difficult to further align and weld the metal pipes with the tail end of the previous section of the metal pipe.

[0038] Based on this, the present application provides a pipeline transportation device, which realizes the transportation of metal pipelines through a vehicle body that can shuttle between concrete prefabricated pipes, wherein the steering wheel group at the front end can adjust the direction in time to improve the alignment accuracy of the two pipelines, and through the cooperation of the hydraulic system and the support rod, the height of the pipeline can be fine-tuned and fixed after the pipeline is transported to the position, so that the pipelines at both ends are accurately aligned and the stability of the rear section of the pipeline during welding is guaranteed; by setting the power assembly and the driving wheel group at the rear end of the vehicle body and setting the steering wheel group at the front end of the vehicle body, the gravity of the power assembly can be used to ensure that the driving wheel group has sufficient friction with the track or the ground, and the front end of the vehicle body can be easier to lift up and enter the concrete prefabricated pipe.

[0039] The present application will be described in detail below through specific embodiments.

[0040] Reference Figures 1 to 4 As shown, this embodiment provides a pipeline transportation device, including: a body 11, a driving wheel group 12, a steering wheel group 13, a power assembly 14 and a support frame 15; the driving wheel group 12 is arranged at the rear end of the body 11, the steering wheel group 13 is arranged at the front end of the body 11, and at least two support frames 15 are arranged along the length direction of the body 11, and are used to support the pipeline 2; the power assembly 14 is arranged at the rear end of the body 11, and is used to drive the driving wheel group 12 to rotate; the support frame 15 includes a base 151, two support rods 152 symmetrically arranged on both sides of the axis of the body 11, and a hydraulic system 153, the support ends of the two support rods 152 are both slidably matched with the base 151, and the hydraulic system 153 is used to drive the support ends of the two support rods 152 to extend and retract. It should be understood that the driving wheel group 12 and the steering wheel group 13 are both located on the outside of the pipeline 2, and the body 11 passes through the center of the pipeline 2, that is, the length of the body 11 is greater than the length of a section of the pipeline 2.

[0041] The pipeline transportation device provided in this embodiment realizes the transportation of the metal pipeline 2 through the vehicle body 11 that can shuttle between the concrete prefabricated pipes, wherein the steering wheel group 13 located at the front end can adjust the direction in time to improve the alignment accuracy of the two pipelines 2. Through the cooperation of the hydraulic system 153 and the support rod 152, the height of the pipeline 2 can be fine-tuned and fixed after the pipeline 2 is transported to the right place, so that the pipelines 2 at both ends are accurately aligned and the stability of the rear section of the pipeline 2 during welding is guaranteed; by arranging the power component 14 and the driving wheel group 12 at the rear end of the vehicle body 11 and arranging the steering wheel group 13 at the front end of the vehicle body 11, the gravity of the power component 14 can be used to ensure that the driving wheel group 12 can have sufficient friction with the track or the ground, and the front end of the vehicle body 11 can be more easily tilted and enter the concrete prefabricated pipe.

[0042] Optionally, a top block 154 is provided on the supporting end of the support rod 152, and the top block 154 is hinged to the supporting end of the support rod 152. It should be noted that the top of the top block 154 has a flat or curved surface that fits the inner wall of the pipe 2, thereby supporting the pipe 2.

[0043] Furthermore, based on the top block 154 hinged to the supporting end of the support rod 152, when the top block 154 pushes upward against the inner wall of the pipe 2, the internal stress of the support frame 15 can be reduced by utilizing its own rotation and sliding with the inner wall of the pipe 2. At the same time, the top block 154 can also move to a suitable position and angle by itself, thereby improving the supporting stability of the top block 154 on the pipe 2.

[0044] Continue to refer to Figure 3 As shown, the support rod 152 extends in the radial direction of the pipeline 2 .

[0045] Furthermore, based on the above-mentioned support rod 152, the support rod 152 can lift the pipeline 2 upward while also transmitting its supporting force on the pipeline 2 in the radial direction of the pipeline 2, and then transferring it to the base 151, thereby providing a more stable and reliable supporting effect for the pipeline 2.

[0046] Optionally, the two support rods 152 each include a sleeve 1521 and a rod body 1522 , the rod body 1522 is slidably plugged into the sleeve 1521 , the sleeve 1521 is fixedly connected to the base 151 , and the hydraulic system 153 is used to drive the rod body 1522 to extend and retract.

[0047] Furthermore, based on the above-mentioned support rod 152, the extension and retraction of the rod body 1522 can be utilized to support the inner wall of the pipe 2, without the need for the entire support rod 152 to reciprocate in the radial direction of the pipe 2, thereby reducing the mass and volume of the moving object and improving the stability of the entire support frame 15 during operation.

[0048] Continue to refer to Figure 1 and Figure 2As shown, the two sleeves 1521 are connected by a reinforcing rod 155 extending in the horizontal direction, that is, the Y-shaped support frame 15 is transformed into an inverted A-shaped support frame 15 by the reinforcing rod 155.

[0049] Furthermore, based on the arrangement of the reinforcing rod 155 , the connection between the two sleeves 1521 can be made more stable and the overall strength is greater, thereby further improving the stability and reliability of the support frame 15 when transporting the pipeline 2 and supporting the pipeline 2 .

[0050] Optionally, the hydraulic system 153 includes an oil pump 1531 and an oil reservoir 1532 , and the oil pump 1531 and the oil reservoir 1532 are both disposed at the rear end of the vehicle body 11 .

[0051] Furthermore, based on the hydraulic system 153 , the weight of the rear end of the vehicle body 11 can be further increased, thereby further improving the friction between the driving wheel set 12 and the ground or the track.

[0052] Optionally, a warning light 16 is provided at the front end of the vehicle body 11, and / or a warning light 16 is provided at the front side of the support frame 15 located at the front end, and / or a warning light 16 is provided at the rear side of the support frame 15 located at the rear end.

[0053] Furthermore, based on the setting of the above-mentioned warning light 16, workers can be reminded, and a sound alarm device such as a buzzer can also be provided on the warning light 16, thereby improving the safety of the pipeline transportation device during operation.

[0054] Optionally, the power assembly 14 includes an electric motor 141 transmission-connected to the drive wheel assembly 12 and a battery 142 for supplying power to the electric motor 141. The power assembly 14 also includes a generator 143 electrically connected to the battery 142 and a fuel tank 144 for supplying fuel to the generator 143. The electric motor 141, the battery 142, the generator 143 and the fuel tank 144 are arranged inside the rear end of the vehicle body 11 or on the side wall of the rear end of the vehicle body 11.

[0055] Further, see Figure 4 As shown, based on the above-mentioned power assembly 14, the gasoline or diesel in the fuel tank 144 can be used to enable the generator 143 to generate electricity and store it in the battery 142. The electricity generated by the generator 143 can also directly drive the motor 141 to rotate, thereby driving the driving wheel group 12 to rotate. In other words, when the battery 142 fails, as long as there is oil in the fuel tank 144, the motor 141 can continue to work. The dual energy reserves of the fuel tank 144 and the battery 142 can significantly improve the endurance and reliability of the entire pipeline transportation device.

[0056] Optionally, an operating component is provided at the front end of the vehicle body 11, and the operating component includes a steering wheel 171, a power control component 172 and a brake control component 173. The steering wheel 171 is connected to the steering wheel group 13 in a transmission manner and is used to drive the steering wheel group 13 to steer. It should be noted that the steering wheel group 13 located at the front end of the vehicle body 11 is located on the axis of the vehicle body 11. Specifically, the steering wheel group 13 can be a single wheel or a double wheel or a multi-wheel structure, as long as it is arranged at the axis position of the vehicle body 11. This not only facilitates its entry into the precast concrete pipe, but also facilitates the steering wheel 171 to control its rotation, thereby reducing interference and resistance with the inner wall of the precast concrete pipe. The driving wheel group 12 located at the rear end of the vehicle body 11 can be a double wheel structure symmetrically arranged on both sides of the axis of the vehicle body 11, thereby forming a stable triangular support structure to improve the overall stability of the vehicle body 11. When the steering wheel group 13 moves into place, the driving wheel group 12 can enter the precast concrete pipe. It can also be located on the track outside the concrete prefabricated pipe. Specifically, the height difference between the steering wheel group 13 and the driving wheel group 12 can be adjusted according to actual conditions, thereby further improving the flexibility and universality of the pipeline transportation device; the power control component 172 and the brake control component 173 are both electrically connected to the power component 14, and the brake control component 173 can be achieved by giving a brake signal to the controller and utilizing the deceleration or self-locking of the motor 141 to achieve braking, or the controller can achieve braking by controlling the brakes located on the driving wheel group 12 and / or the steering wheel group 13, wherein the controller can be set on the vehicle body 11, as long as the power control component 172 and the brake control component 173 are located at the front end of the vehicle body 11, it is convenient for workers to operate. It should be noted that the power control component 172 can control the output power of the motor 141 to change within a certain range, and the brake control component 173 can control the resistance provided by the brake or the motor 141 to change within a certain range.

[0057] Furthermore, based on the above-mentioned operating components, workers can more conveniently control the forward direction and operating status of the vehicle body 11, and at the same time, the forward, backward and braking movements of the vehicle body 11 can be smoother, avoiding sudden acceleration and sudden braking, which affects the transportation and welding of the pipeline 2.

The vehicle body 11 may specifically be a tubular structure, and the electric wires and oil circuits are arranged inside the vehicle body 11 .

[0059] Furthermore, based on the above vehicle body 11 , all control circuits on the vehicle body 11 can be built-in, thereby reducing external interference to the control circuits in the vehicle body 11 , and further improving the safety and reliability of the vehicle body 11 .
