[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0027] To further understand the content of the present utility model, the following further elaborates on this technical solution in combination with specific implementation manners.

[0028] Embodiment 1: As Figures 1 to 5 shown, this embodiment provides a tunnel automatic pipe transporting and assembling device, which includes a traveling mechanism for transporting a pipe 14, a carrying platform 8 for supporting the pipe 14, a jacking mechanism for jacking the pipe 14 to a designated position, a position adjusting mechanism for adjusting the horizontal degree of freedom of the pipe 14, a collision prevention warning system for safety monitoring, and a PLC controller. The PLC controller is electrically connected to the traveling mechanism, the jacking mechanism, the position adjusting mechanism, and the collision prevention warning system.

[0029] Specifically, the traveling mechanism includes a vehicle body 6, a wheel set 1, and a driving mechanism. The driving mechanism is installed on the vehicle body 6. The driving mechanism controls the rolling of the wheel set 1, and then the wheel set 1 drives the vehicle body 6 to move. Among them, the wheel set 1 uses aviation tires. Replacing traditional automobile tires with aviation tires increases the bearing capacity, can carry large-diameter pipes 14, and can complete the transportation of pipe materials with a weight less than 10t. The vehicle body 6 is equipped with a four-wheel drive conversion device to increase the torque and can achieve four-wheel drive two-way driving, which is convenient for dealing with various working conditions. The driving mechanism includes a battery pack 7, a motor 2, a speed reducer 3, and a transmission component. The battery pack 7 provides power for the motor 2. The motor 2 is connected to the speed reducer 3. The speed reducer 3 controls the rotation of the wheel set 1 through the transmission component. Taking the battery as the driving force, compared with fuel vehicles, it solves the problem that the exhaust gas pollution in the tunnel affects the health of construction workers.

[0030] The carrying platform 8 is placed above the vehicle body 6. On this basis, a receiving groove 9 along the length direction of the vehicle body 6 is provided in the middle of the carrying platform 8. The receiving groove 9 is used to support the pipe 14 to prevent the pipe 14 from shaking or rolling during transportation;

[0031] The jacking mechanism includes a hydraulic cylinder 5 and a hydraulic pump 4. The hydraulic pump 4 provides power for the hydraulic cylinder 5. The hydraulic cylinder 5 is installed at each corner of the bottom of the carrying platform 8, and the hydraulic rod of the hydraulic cylinder 5 faces the ground.

[0032] The position adjustment mechanism includes a bracket 16, an electric telescopic rod 15, and a position sensor for monitoring the position of the pipeline 14. The electric telescopic rod 15 is installed at the top of the bracket 16, and both the bracket 16 and the position sensor are installed on the carrying platform 8. Specifically, the bracket 16 is located on both sides of the pipeline 14 respectively, and the electric telescopic rods 15 are arranged facing each other, that is, both are facing the direction where the pipeline 14 is located.

[0033] The anti-collision warning system includes an infrared detector 11 and an alarm 10. The infrared detectors 11 are installed around the vehicle body 6. The infrared detectors 11 and the alarm 10 are electrically connected to the PLC controller. Specifically, the infrared detector 11 measures the distance, and the set distance boundary value is 0.5 m. When the distance between the utility model and the inner wall of the tunnel is less than 0.5 m, the alarm 10 gives an alarm; or when the infrared detector 11 detects an obstacle, the alarm 10 gives an alarm, and the operator makes an avoidance treatment.

[0034] The alarm 10 adopts an audible and visual alarm 10, which emits a warning signal to the on-site operator through sound and various lights.

[0035] On this basis, a pipeline fixing mechanism for preventing the pipeline 14 from shaking is further provided on the carrying platform 8. The pipeline fixing mechanism includes a connecting piece, a strap 12, and a buckle 13. The connecting pieces are evenly distributed on both sides of the accommodating groove 9 of the carrying platform 8. Both ends of the strap 12 are connected to the buckle 13, and the buckle 13 can be locked on the connecting piece or separated from the connecting piece.

[0036] Embodiment 2:

[0037] The carrying platform 8 is placed above the vehicle body 6. Different from Embodiment 1, as Figure 6 shown, the accommodating groove 9 for placing the pipeline 14 is not provided in the middle of the carrying platform 8. This carrying platform 8 is a flat plane, and the pipeline 14 is directly placed on the carrying platform 8. Sleepers 17 are placed on both sides of the pipeline 14 to limit the rolling of the pipeline 14.

[0038] On this basis, the same as Embodiment 1, the pipeline 14 is bundled and fixed by the pipeline fixing mechanism. The pipeline fixing mechanism includes a connecting piece, a strap 12, and a buckle 13. The connecting pieces are evenly distributed on both sides of the carrying platform 8. Both ends of the strap 12 are connected to the buckle 13, and the buckle 13 can be locked on the connecting piece or separated from the connecting piece.

[0039] Taking Embodiment 1 as an example, in the actual application process, first place the pipeline 14 in the accommodating groove 9. The operator winds the binding strap 12 around the outer periphery of the pipeline 14 and buckles the lock 13 on the connecting piece to bind and fix the pipeline 14 to prevent the pipeline 14 from shaking or slipping out. Subsequently, the driving mechanism controls the vehicle body 6 to move. During the process, the anti-collision warning system monitors the road conditions in real time, can automatically identify obstacles, and the operator clears the obstacles. The vehicle body 6 is equipped with a four-wheel drive conversion device to increase the torque and can achieve four-wheel drive bidirectional driving, which is convenient for dealing with various working conditions. For example, when the distance from the inner wall of the tunnel is less than 0.5 m, the alarm 10 automatically alarms to remind the driver to control the vehicle body 6 to retreat to prevent collision with the tunnel lining masonry during pipe transportation in the tunnel. When the vehicle body 6 reaches the designated position and the pipeline 14 needs to be butt-jointed, unlock and loosen the lock 13 from the connecting piece. The hydraulic cylinder 5 in the lifting mechanism extends. After the hydraulic rod contacts the ground, due to the reaction force, the hydraulic cylinder 5 lifts the carrying platform 8, and then drives the pipeline 14 to rise to the designated height. Subsequently, the electric telescopic rods 15 in the position adjustment mechanisms on both sides of the pipeline 14 extend to adjust the horizontal direction of the pipeline 14 so that the pipe orifices of the two pipelines 14 are exactly opposite, that is, the two pipelines 14 are butt-jointed. During the process, the position sensor monitors the position of the pipeline 14, and then subsequent processes such as welding are carried out. The vertical and horizontal position adjustments of the pipeline 14 are realized through the lifting mechanism and the position adjustment mechanism, reducing the manual intensity and improving the construction efficiency.

[0040] It should be noted that the traveling mechanism is a prior art and will not be described in detail herein. Those skilled in the art can also replace the wheel set with a crawler-type traveling, and the hydraulic cylinder can also be replaced with a lifting device such as a stepping motor.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
