DETAILED DESCRIPTION

[0053] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings so that the purpose, features and advantages of the present invention can be more clearly understood. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0054] The present invention provides a tunnel secondary lining concrete intelligent walking temperature control maintenance trolley, specifically Figure 1-6 As shown, it includes a first traveling frame 1, a second traveling frame 2, an arc-shaped bracket 3, a temperature-controlled spray device 4 and a plurality of swing components 5; a friction beam 101 is longitudinally arranged on the top of the first traveling frame 1, the second traveling frame 2 is arranged above the first traveling frame 1, and is slidably connected to the friction beam 101, the arc-shaped bracket 3 is arranged on the second traveling frame 2, and the inner side of the arc-shaped bracket 3 is slidably connected to the first traveling frame 1; the temperature-controlled spray device 4 is arranged on the arc-shaped bracket 3, and a plurality of swing components 5 are arranged on the arc-shaped bracket 3, and are transmission-connected to the temperature-controlled spray device 4.

[0055] In this embodiment, when the tunnel needs to be maintained, the first traveling frame serves as the basic mobile platform of the entire equipment and can move freely in the working area. At the same time, the second traveling frame moves forward and backward on the friction beam on the top of the first traveling frame, driving the arc-shaped bracket to move in the tunnel, so that the temperature-controlled spraying device set on the arc-shaped bracket moves in the tunnel. The temperature-controlled spraying device can spray the second lining concrete in the tunnel according to the preset temperature and spraying amount, ensuring that the sprayed hot water is close to the surface temperature of the concrete. At the same time, multiple groups of swing components can work according to the preset swing angle and frequency, thereby driving the temperature-controlled spraying device to spray a large area in the tunnel, improving the uniformity and coverage of the spraying.

[0056] In one embodiment, the first walking frame 1 includes a first bottom beam 102, a second bottom beam 103, a plurality of portal frames 108, a walking drive device 104, and a walking steering device 109; a plurality of portal frames 108 are arranged across the first bottom beam 102 and the second bottom beam 103, and a plurality of connecting beams 8 are arranged between the plurality of portal frames 108; longitudinal beams 105 are arranged at the top ends of both sides of the portal frames 108, each longitudinal beam 105 is arranged with a sliding rod 106, a sliding block 107 is slidably connected to the sliding rod 106, and the sliding block 107 is connected to the arc bracket 3; the walking drive device 104 is arranged at one end of the bottom of the first bottom beam 102 and the second bottom beam 103; the walking steering device 109 is arranged at one end of the bottom of the first bottom beam 102 and the second bottom beam 103 away from the walking drive device 104.

[0057] In one embodiment, the travel drive device 104 includes a driving wheel 1041 and a reduction motor 1043; the driving wheel 1041 is arranged at one end of the bottom of the first bottom beam 102 or the second bottom beam 103 through the first bracket 6, and a ring gear 1042 is arranged on the outer side of the driving wheel 1041; the reduction motor 1043 is arranged on the outer side of the first bracket 6, and the output end gear of the reduction motor 1043 is meshed with the ring gear 1042.

[0058] In one embodiment, the walking steering device 109 includes a steering wheel 1091, a steering vertical shaft 1092 and an electro-hydraulic servo cylinder 1094. The steering wheel 1091 is arranged at the bottom of the first bottom beam 102 or the second bottom beam 103 through the second bracket 20; the bottom end of the steering vertical shaft 1092 is connected to the second bracket 20, and the top end passes through the upper bottom surface of the first bottom beam 102 or the second bottom beam 103 and is connected to an ear bracket 1093; the electro-hydraulic servo cylinder 1094 is hinged on the upper bottom surface of the first bottom beam 102 or the second bottom beam 103, and the output shaft of the electro-hydraulic servo cylinder 1094 is connected to the ear bracket 1093.

[0059] Specifically, a first sensor is provided at the end of the driving wheel 1041 of the first bottom beam 102, a second sensor is provided at the end of the driving wheel 1041 of the second bottom beam 103, a third sensor is provided at the end of the steering wheel 1091 of the first bottom beam 102, and a fourth sensor is provided at the end of the steering wheel 1091 of the second bottom beam 103; a left turn limiter 16, a reset sensor 17 and a right turn limiter 18 are provided on the outer side of the ear frame 1093 in sequence.

[0060] When the first traveling frame 1 needs to be started, the reduction motor 1043 starts working, and the gear at its output end meshes with the gear ring 1042 on the outer side of the driving wheel 1041, thereby driving the first traveling frame 1 forward or backward. Since a set of traveling driving devices 104 are respectively provided at the bottom of the first bottom beam 102 and the second bottom beam 103, the frame can move stably and evenly. When the traveling direction needs to be changed, the electro-hydraulic servo cylinder 1094 starts working. By adjusting the connection angle between the output shaft of the electro-hydraulic servo cylinder 1094 and the ear frame 1093, the direction of the steering vertical shaft 1092 and the steering wheel 1091 connected thereto can be changed. In this way, the first traveling frame 1 can turn left or right as needed. During the driving process, the first sensor, the second sensor, the third sensor and the fourth sensor enter the working state. These sensors are used to monitor the obstacles and boundaries around the trolley in real time to ensure safe driving. When turning, the left turn limiter 16 limits the maximum left turn angle of the steering wheel 1091, and the right turn limiter 18 limits the maximum right turn angle of the steering wheel 1091 to prevent damage to the frame or loss of control caused by oversteering. The reset sensor 17 is used to confirm that the steering wheel 1091 has returned to the initial position after the steering is completed to ensure the straight-line driving ability of the frame.

[0061] In one embodiment, a sliding driving wheel 201 is provided at the bottom center of the second traveling frame 2, and the sliding driving wheel 201 is slidably connected to the friction beam 101. When the second traveling frame 2 needs to be moved, the driving motor connected to the sliding driving wheel 201 is started, and the sliding driving wheel 201 starts to rotate under the action of the driving force, so that the second traveling frame 2 slides and moves along the length direction of the friction beam 101 (i.e., the length direction of the tunnel).

[0062] In one embodiment, the temperature control spray device 4 includes a rotating tube 401, a connecting hose 402, and a heating water tank 403; the rotating tube 401 is arranged on the arc bracket 3 through a fixed sleeve 9, and a plurality of nozzles 404 are arranged at intervals on the rotating tube 401; one end of the connecting hose 402 is connected to the rotating tube 401 through a rotating joint; the heating water tank 403 is arranged on the connecting beam 8, and a water inlet pipe 405 is arranged on the top of the heating water tank 403, and a first electromagnetic water valve 406 and a booster pump 408 are connected to the bottom through a water outlet pipe, and the outlet pipe of the booster pump 408 is connected to the connecting hose 402. The temperature controller 15 is arranged on the column 21 at the upper part of the door frame 108 and close to the heating water tank 403, and the column 21 is located between the two layers of connecting beams 8.

[0063] Optionally, a drag chain 14 is provided on the median side of the connecting beam 8 , a connecting hose 402 and a waterproof cable are placed in the drag chain 14 , and every two sections of the connecting hose 402 are connected via a connector.

[0064] Furthermore, an overflow alarm 10 is provided at the top of the heating water tank 403 near the water inlet pipe 405. The overflow alarm is used to sound an alarm when the water level in the heating water tank exceeds a preset safety height to prevent water from overflowing. A liquid level controller 11 is provided in the middle of the heating water tank 403. The liquid level controller is used to monitor and control the water level in the heating water tank. It can control the switch of the water inlet pipe according to the height of the water level, so as to keep the water level in the heating water tank within a preset range. Such a configuration can ensure the safe operation of the heating water tank 403, prevent water from overflowing, and maintain a stable water level.

[0065] Furthermore, multiple columns are arranged on the upper part of the door frame 108, and the multiple columns are arranged between the two layers of connecting beams 8. The multiple columns divide multiple storage spaces, and the smoke exhaust fan 13, the temperature controller 15, the heating water tank 403 and the water collecting tank 701 located on the heating water tank 403 are placed in sequence from left to right; the outer periphery of the smoke exhaust fan 13 is provided with an air duct 12. The exhaust fan in the air duct can perform smoke exhaust operations.

[0066] When it is necessary to start the spraying operation, first open the first electromagnetic water valve 406 through the control system, start the booster pump 408, and transport the water in the heating water tank 403 to the rotating tube 401 through the outlet pipe, the opened first electromagnetic water valve and the connecting hose 402. Multiple nozzles 404 are arranged at intervals along the rotating tube 401. When the water flows through, the nozzles 404 spray water in the form of mist or streams to complete the spraying operation. After the second lining concrete is demoulded, the maintenance trolley is driven under the second lining concrete 19, and water is injected into the heating water tank 403 through the water inlet pipe 405 until the overflow alarm 10 alarms. At the same time, when the water temperature of the heating water tank 403 reaches the time period temperature set by the temperature controller, the sliding drive wheel 201 is started to rotate, driving the arc bracket 3 to run back and forth along the length direction of the tunnel. At the same time, the booster pump 408 and the first electromagnetic water valve 406 are started, so that hot water passes through the connecting hose 402 in the drag chain, through the rotating tube 401, and then sprayed from the nozzle 404 to the surface of the secondary lining concrete. At this time, the temperature is close to the time-varying temperature of the concrete, achieving the purpose of maintenance.

[0067] In one embodiment, a tunnel secondary lining concrete intelligent walking temperature control maintenance trolley also includes a water collecting device 7, which includes a water collecting tank 701, a guide groove 703, and a water collecting funnel 704; the water collecting tank 701 is arranged above the heating water tank 403, and the water outlet pipe of the water collecting tank 701 is connected to the second electromagnetic water valve 407, and the water outlet of the second electromagnetic water valve 407 is connected to the heating water tank 403, and the upper end surface of the water collecting tank 701 is provided with a return water bell mouth 702; the guide groove 703 is arranged above the water collecting tank 701, and the lower return water outlet of the guide groove 703 is connected to the return water bell mouth 702; the water collecting funnel 704 is arranged above the guide groove 703 and is connected to the longitudinal beam 105.

[0068] As a preferred embodiment, the water collecting funnel 704 is composed of two closed plates, which are obliquely arranged on the longitudinal beam 105. The two closed plates are inclined to form a funnel shape, and the funnel is convenient for the reflux collection of excess atomized water.

[0069] During the maintenance process, excess atomized water is sprayed through the water collecting funnel 704, the diversion groove 703, and the return water bell mouth 702 to store the water in the water collecting tank 701. After the maintenance trolley returns to the starting position as a whole, the second solenoid water valve 407 is opened after a delay of N seconds, and the excess water flows back to the heating water tank 403 for continued heating, and circulated spraying is performed to reduce the waste of water resources.

[0070] In one embodiment, the swing assembly 5 includes an electric push rod 501, three swing links 502, a first link 503 and a second link 504; the electric push rod 501 is arranged on the inner side of the arc-shaped bracket 3; each swing link 502 is connected to the fixed sleeve 9; the first link 503 and the second link 504, the first link 503 and the second link 504 are hinged to each other to form a first hinge point, the first swing link 502 is hinged at the first hinge point, and the first swing link 502 is hinged to the telescopic end of the electric push rod 501; the end of the first link 503 away from the first hinge point is hinged to the second swing link 502; the end of the second link 504 away from the first hinge point is hinged to the third swing link 502.

[0071] When the electric push rod 501 is started, its telescopic end will move forward or backward. Since the first swing link 502 is hinged to the telescopic end of the electric push rod, the movement of the electric push rod will drive the first swing link 502 to move. As the first swing link 502 moves, since it is connected to the first link 503 and the second link 504 at the first hinge point, the relative position of the first link 503 and the second link 504 will change. The second swing link 502 connected to the first link 503 will move accordingly, thereby driving the second swing link 502 to move, and then driving the third swing link 502 to move.

[0072] According to the different diameters of the tunnel section, the electric push rod 501, the swing link 502, the first link 503, the second link 504, the rotating tube 401 and other components are designed in groups to meet different operation requirements.

[0073] Explanation is that an insulated and enclosed integrated electric control box is also installed on the door frame 108, and a control center is installed in the integrated electric control box, and the control center includes a PLC, etc. The control center is connected to the reduction motor 1043, the electro-hydraulic servo cylinder 1094, the sliding drive wheel 201, the first electromagnetic water valve 406, the second electromagnetic water valve 407, the booster pump 408, the overflow alarm 10, the liquid level controller 11, the smoke exhaust fan 13, the temperature controller 15, the electric push rod 501, the first sensor, the second sensor, the third sensor, the fourth sensor, the left turn limiter 16, the reset sensor 17, and the right turn limiter 18 through wires.

[0074] The present invention provides a tunnel secondary lining concrete intelligent walking temperature control maintenance trolley. When the tunnel needs to be maintained, the reduction motor is first started to work, and the gear at the output end thereof is meshed with the gear ring on the outer side of the driving wheel, thereby driving the first walking frame to walk in the tunnel. When the walking direction needs to be changed, the electro-hydraulic servo cylinder starts to work. By adjusting the connection angle between the output shaft of the electro-hydraulic servo cylinder and the ear frame, the direction of the steering vertical axis and the steering wheel 1 connected thereto can be changed. In this way, the first walking frame can turn left or right as needed. During the travel process, the first sensor, the second sensor, the third sensor and the fourth sensor enter the working state. These sensors are used to monitor the obstacles and boundaries around the trolley in real time to ensure safe driving; secondly, when the spraying operation needs to be started, the first electromagnetic water valve is first opened through the control system, and the booster pump is started to transport the water in the heating water tank to the rotating pipe through the outlet pipe, the opened first electromagnetic water valve and the connecting hose. Multiple nozzles are arranged at intervals along the rotating pipe. When the water flows through, the nozzle sprays the water in the form of mist or thin stream to complete the spraying operation. After the second lining concrete is demoulded, the maintenance trolley is driven under the second lining concrete, and water is added to the heating water tank through the water inlet pipe until the overflow alarm sounds. At the same time, when the water temperature of the heating water tank reaches the time period temperature set by the temperature controller, the sliding drive wheel is started to rotate, driving the arc bracket to run back and forth along the length of the tunnel. At the same time, the booster pump and the first electromagnetic water valve are started, so that the hot water passes through the connecting hose in the drag chain, through the rotating tube, and then from the nozzle to spray the hot water on the surface of the second lining concrete. At this time, the temperature is similar to the time-varying temperature of the concrete, achieving the purpose of maintenance. Finally, during the maintenance process, the excess atomized water sprayed is stored in the water collection tank through the water collection funnel, the diversion trough, and the return water horn. After the maintenance trolley returns to the starting position as a whole, the second electromagnetic water valve is opened after a delay of N seconds, and the excess water flows back to the heating water tank for continued heating, and the circulation spraying is carried out to reduce the waste of water resources.
