[0026] In order to make the technical means and objectives of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments. A tunnel automatic transportation management group pairing device, such as Figure 1-Figure 3 , Figure 5 As shown, it includes a platform vehicle, a hydraulic adjustment system 5, and a U-shaped carrying platform 7.

A steel pipe is placed on the U-shaped carrying platform 7. The platform vehicle controls the lifting and left and right adjustment functions of the U-shaped carrying platform 7 through the hydraulic adjustment system 5.

[0027] The tires of the platform vehicle are aviation tires 1.

[0028] Wherein, the platform vehicle is provided with a four-wheel drive conversion system 2.

[0029] Wherein, the platform vehicle is provided with an infrared sound and light alarm 4.

[0030] Wherein, the platform vehicle is provided with a wireless remote control system 6.

[0031] The four-wheel drive conversion system 2 , the infrared sound and light alarm 4 , the hydraulic adjustment system 5 , and the wireless remote control system 6 are all connected to the battery 3 .

[0032] Among them, a platform vehicle is used as a carrier, a battery 3 is used as a driving force, a U-shaped carrying platform 7 is set up, an aviation tire 1 is used to increase the carrying capacity, an infrared sound and light alarm 4 and a wireless remote control system 6 are added, obstacles are automatically identified, and automatic transportation and management are realized; a four-wheel drive conversion system 2 is installed to increase the torque of the transportation and management device and realize four-wheel drive two-way driving; a hydraulic adjustment system 5 is equipped to complete the jacking and left and right adjustment functions and realize the pairing function.

[0033] The present invention uses a platform vehicle as a carrier, sets a U-shaped carrying platform and a fixing device, uses aviation tires instead of traditional automobile tires, increases the carrying capacity, and can carry and transport pipes with a diameter of less than Φ1219 and a weight of less than 10t; uses batteries as driving force, solves the problem of exhaust pollution in tunnels affecting the health of construction workers; adds an infrared sound and light alarm and a wireless remote control system to the device, can automatically identify obstacles, and realize automatic transportation and management; is equipped with a four-wheel drive conversion device, increases the torque of the transportation and management device, and can realize four-wheel drive two-way driving; is equipped with a hydraulic adjustment system, can complete the jacking and left and right adjustment functions, realizes the grouping function, reduces the labor intensity and improves the construction efficiency.

[0034] A construction process for a tunnel automatic operation and management assembly device, such as Figure 4 As shown, the following steps are included:

[0035] S1. Hoist the working pipe onto the platform vehicle;

[0036] S2, platform vehicle realizes automatic transportation and management;

[0037] S3. After the pipeline is in place, install the pipeline support pier;

[0038] S4, automatically adjust the gap between pipe groups;

[0039] S5. Use automatic welding to complete the bottom welding of the pipeline weld;

[0040] S6, pipe weld filling and capping welding;

[0041] S7. Anti-corrosion patching of pipeline welds.

[0042] The present invention has two options for power selection, one is a fuel-driven vehicle and the other is an electric-driven vehicle. Considering the carrying power and the impact of smoke and exhaust gas in the tunnel, a battery-driven vehicle is finally selected as the carrier of the automatic group transport management device;

[0043] Consider two options for the loading platform: flat-bed type and U-shaped type. Considering the characteristics of the automatic pipe transport vehicle in preventing the pipeline from lateral sliding and swinging during transportation, the U-shaped loading platform and fixing device are selected, such as Figure 3 As shown;

[0044] For the walking system of the automatic transport and management group, we considered two options: wheeled and crawler. Although the crawler has advantages in self-locking and friction, the transport and management device is long and has a long walking distance, which makes it easy for the crawler to fall off. Therefore, we chose wheeled + motor self-locking. For the tire selection, we chose vacuum tires and aviation tires. Considering the tunnel transportation conditions, we chose solid aviation tires to increase the load-bearing capacity and be able to transport pipes with a diameter of less than Φ1219 and a weight of less than 10t.

[0045] In order to prevent the tunnel transportation and management from colliding with the tunnel lining, an infrared sound and light alarm and a wireless remote control system are added to the transportation and management group device, which can automatically identify obstacles and realize automatic transportation and management; a four-wheel drive conversion device is installed to increase the torque of the transportation and management device, which can realize four-wheel drive two-way driving;

[0046] In the selection of the jacking and adjustment system, we proposed two solutions: one is a stepper motor + reducer, and the second is a hydraulic adjustment system. Due to the limitations of adjustment time, adjustment space and adjustment weight, the stroke of the stepper motor cannot meet the technical requirements. In the end, we chose the hydraulic adjustment system, which can complete the jacking and left and right adjustment functions, realize the grouping function, reduce labor intensity and improve construction efficiency.

[0047] After the invention was successfully developed and tested, it has been applied to tunnel construction in oil fields, completing 11.6 km of tunnel construction, 7 km of pipelines with a diameter of Φ813×16.8 mm, and 4.6 km of pipelines with a diameter of Φ1219×21 mm.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
