[0014] An operation method of a subway tunnel steel ring reinforcement operation vehicle, used for the above-mentioned subway tunnel steel ring reinforcement operation vehicle, is characterized by comprising the following operation method steps: Step 1: Equipment preparation: First, place the equipment in the subway tunnel and on the designated moving track to facilitate the movement of the equipment. Then, place the steel ring used for reinforcement on the support assembly so that the central axis of the steel ring coincides with the central axis of the mounting frame. Then, through the rotating structure between the connecting ball and the connecting sleeve, the contact plate can automatically adjust its angle so that the contact plate fits the surface of the steel ring. Step 2: Horizontal adjustment: Then turn on the power wheel, and the staff moves the equipment through the power of the power wheel, so that the steel ring moves to the installation position. If the vehicle body tilts during the movement, the slider will slide on the lower surface of the power supply box. The lower surface of the power supply box has a track to guide the slider, so that the sliding direction of the slider can be determined. When the slider slides, it will contact the docking block, so that the first electrode and the second electrode are docked, so that the battery will supply power to the motor through the first electrode and the second electrode, so that the motor works and the first threaded rod rotates. The first threaded rod is extended by relying on the threaded connection between the first threaded rod and the threaded sleeve, so as to adjust the angle of one side of the power supply box and restore the power supply box to a horizontal state. After the power supply box is restored to a horizontal state, the slider will not be pulled by lateral gravity.

The worker can install guardrails and other protective devices around the standing platform according to work requirements. After the worker stands, the worker bends the bendable pipe so that the air outlet of the bendable pipe is aligned with the surface of the steel ring. In this way, the steel ring can be cleaned with gas when the bendable pipe is deflated, thereby avoiding the need for workers to clean the surface after the steel ring is installed; Step 4: Push up and make contact: When all preparations are done, turn on the fan and fill the telescopic jacket with gas through the air duct, so that the air pressure inside the telescopic jacket increases, and the telescopic inner rod extends, thereby pushing the steel ring and making the steel ring contact with the tunnel, so that it is convenient for the staff to install the steel ring on the tunnel. When pushing on the steel ring, the pressure will also be relieved through the pressure relief component, so that the telescopic inner rod maintains a constant upward thrust, which is convenient for the equipment to press the steel ring onto the tunnel; Step 5: Height adjustment: After the steel ring contacts the tunnel, the staff can adjust the height of the standing platform through the cylinder so that the staff can reach the steel ring and use screws to install and fix the steel ring; Step 6: Angle control: After the steel ring is installed, the slide rail will be pushed by the two-way cylinder to unfold the two telescopic sleeves, so that the contact plate will move along the curvature of the steel ring, making it easier for the staff to gradually fix the steel ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. After the device is tilted, the tilted end of the device will be energized, so that the height of the tilted end can be adjusted to restore the device to a level state, so that the device can work stably.

[0016] 2. The equipment can push the steel ring at a constant pressure, so that the steel ring can be in close contact with the tunnel surface, making it easier for workers to install the steel ring.

[0017] 3. The equipment will use the depressurized gas to clean the steel ring, so that the steel ring is cleaned after the equipment is working, and the staff does not need to perform additional cleaning steps. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 2As shown, the lifting assembly 3 includes a cylinder 301 and a standing platform 302 , and the upper end of the cylinder 301 is connected to the standing platform 302 .

[0026] like Figure 5 As shown, the support assembly 4 includes a mounting frame 401, a two-way cylinder 402, a fan 403, an air duct 404, a slide rail 405, a telescopic outer cover 406 and a telescopic inner rod 407, and the upper end of the mounting frame 401 is installed with a two-way cylinder 402, the front end of the mounting frame 401 is installed with a fan 403, and the air outlet of the fan 403 is connected with the air duct 404, the left and right ends of the two-way cylinder 402 are connected with slide rails 405, and the rear of the slide rails 405 is provided with a telescopic outer cover 406, and the interior of the telescopic inner rod 407 is installed. The support assembly 4 includes a mounting frame 401, a two-way cylinder 402, a fan 403, an air duct 404, a slide rail 405, a telescopic outer cover 406 and a telescopic inner rod 407. The support assembly 4 further comprises a connecting ball 408, a connecting sleeve 409, a contact plate 410 and a second permanent magnet 411, and the upper end of the connecting ball 408 is connected to the connecting sleeve 409, the upper end of the connecting sleeve 409 is connected to the contact plate 410, and the upper surface of the contact plate 410 is inlaid with the second permanent magnet 411; The equipment can push the steel ring at a constant pressure so that the steel ring can be in close contact with the tunnel surface, making it easier for workers to install the steel ring.

[0027] Working principle: First, place the device in the subway tunnel and on the designated moving track to facilitate the movement of the device. Then, place the steel ring used for reinforcement on the support assembly 4 so that the central axis of the steel ring coincides with the central axis of the mounting frame 401. Then, through the rotating structure between the connecting ball 408 and the connecting sleeve 409, the contact plate 410 can be automatically adjusted in angle, so that the contact plate 410 fits the surface of the steel ring, and the steel ring is adsorbed by the second permanent magnet 411, so that the steel ring will not move randomly on the device. Then the power wheel 208 is turned on, and the staff moves the equipment through the power of the power wheel 208, so that the steel ring moves to the installation position. If the vehicle body tilts during the movement, the slider 104 will slide on the lower surface of the power supply box 101. The lower surface of the power supply box 101 has a track to guide the slider 104, so that the sliding direction of the slider 104 can be determined. When the slider 104 slides, it will contact the docking block 202, so that the first electrode 105 and the second electrode 203 are docked, so that the battery 103 will supply power to the motor 201 through the first electrode 105 and the second electrode 203, so that the motor 201 works and the first threaded rod 204 rotates. The first threaded rod 204 is extended by relying on the threaded connection between the first threaded rod 204 and the threaded sleeve 205, so as to adjust the angle of one side of the power supply box 101, so that the power supply box 101 is restored to a horizontal state. After the power supply box 101 is restored to a horizontal state, the slider 10 4 will not be pulled by the lateral gravity. At this time, the slider 104 will be attracted and reset by the traction force of the first permanent magnet 102. The position where the slider 104 installs the first electrode 105 is made of ceramic material, and the front and rear ends of the slider 104 are made of metal material, which is convenient for the first permanent magnet 102 to attract the slider 104. At the same time, the power supply end of the battery 103 is connected to the first electrode 105 through a wire, so that the first electrode 105 is charged. The relationship between the docking block 202 and the second electrode 203 is the same as the relationship between the slider 104 and the first electrode 105. Both use the above structure for conductivity. When the mounting plate 206 is driven to rise and fall by the threaded sleeve 205, the telescopic rod 207 guides the mounting plate 206. At the same time, the motor 201 is installed inside the power supply box 101 by screws, but the installation of the motor 201 is not fixed. The motor 201 can be slightly swung left and right to balance the angle adjustment of the power supply box 101. After the equipment is moved to the installation position, the worker stands on the standing platform 302. The worker can install guardrails and other protective devices around the standing platform 302 according to work requirements. After the worker stands, the worker bends the bendable pipe 502 so that the air outlet of the bendable pipe 502 is aligned with the surface of the steel ring. In this way, when the bendable pipe 502 is deflated, the steel ring can be cleaned with gas, thereby avoiding the need for workers to clean the surface after the steel ring is installed. When all preparations are done, turn on the fan 403, and fill the telescopic outer sleeve 406 with gas through the air duct 404, so that the air pressure inside the telescopic outer sleeve 406 increases, and the telescopic inner rod 407 extends, thereby pushing the steel ring and making the steel ring contact with the tunnel, so that it is convenient for the staff to install the steel ring on the tunnel. When pushing on the steel ring, the pressure will also be relieved through the pressure relief component 5, so that the telescopic inner rod 407 maintains a constant upward thrust, which is convenient for the equipment to press the steel ring onto the tunnel. The position of the moving block 505 can be adjusted through the threaded connection between the second threaded rod 506 and the connecting sleeve 501, so that the pressure relief degree of the pressure relief component 5 can be adjusted, and the thrust of the telescopic inner rod 407 can be effectively controlled; After the steel ring contacts the tunnel, the worker can adjust the height of the standing platform 302 through the cylinder 301, so that the worker can reach the steel ring, which is convenient for the worker to install and fix the steel ring with screws; After the steel ring is installed, the slide rail 405 is pushed by the bidirectional cylinder 402, so that the two telescopic sleeves 406 are unfolded, which will make the contact plate 410 move along the curvature of the steel ring, making it easier for the staff to gradually fix the steel ring.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
