Description

Technical Field

[0001] This disclosure relates to the field of maintenance equipment, and more particularly to a maintenance vehicle. Background Technology

[0002] Secondary lining curing is the last step in quality control in tunnel lining engineering. If curing is not done in time, it will cause quality defects such as cracking of the concrete surface and failure of the concrete strength to meet the design requirements, which will directly affect the service life of the structure. During the tunnel curing process, it is necessary to spray water on the tunnel wall. Summary of the Invention

[0003] The inventors discovered through research that secondary lining curing in some related technologies mainly relies on manual water spraying, which involves a large workload.

[0056] The secondary lining tunnel maintenance devices in related technologies are all separately configured special construction equipment with relatively simple functions. They cannot perform other functions during non-maintenance periods, resulting in idle equipment, excessive operating costs, and waste of resources.

[0057] In view of this, the present disclosure provides a maintenance vehicle. Figure 1 These are structural schematic diagrams of some embodiments of the maintenance vehicle disclosed herein. Figure 2 These are structural schematic diagrams of other embodiments of the maintenance vehicle disclosed herein, with reference to... Figure 1 and Figure 2 The maintenance vehicle includes: vehicle body 1, water tank 2, water spraying device 3, and tunnel maintenance equipment 4.

[0058] Vehicle body 1 is configured to travel on the road surface. Water tank 2 is connected to vehicle body 1 and configured to store water. Sprinkler device 3 is connected to water tank 2 and configured to sprinkle water onto the road surface. Tunnel maintenance equipment 4 is detachably connected to vehicle body 1 and configured to atomize and maintain the tunnel. Vehicle body 1, water tank 2, and sprinkler device 3 include, but are not limited to, the vehicle body, water tank, and sprinkler device of a road sprinkler truck.

[0059] The tunnel maintenance equipment 4 includes an atomizing device 5 and a position adjustment device 6. The atomizing device 5 is connected to a water tank 2 so that the water tank 2 supplies water to the atomizing device 5, thereby causing the atomizing device 5 to spray water mist. The position adjustment device 6 is connected to the atomizing device 5 and is configured to adjust the position of the atomizing device 5 relative to the water tank 2. (Reference) Figure 1 When the atomizing device 5 is in operation, it stands upright relative to the water tank 2. (Reference) Figure 2 When the atomizing device 5 is in its stored state, it rests against the upper surface of the water tank 2.

[0060] In this embodiment, by setting the position adjustment device 6, the position of the atomizing device 5 relative to the tunnel wall, vehicle body 1 and water tank 2 can be adjusted. In addition to uniformly atomizing and spraying the tunnel during maintenance, the tunnel maintenance equipment 4 can also be stored on the vehicle body 1 during non-maintenance periods, so that the maintenance vehicle can flexibly carry out road transportation and watering and dust removal, thereby improving the utilization rate of the maintenance vehicle, reducing operating costs, and having high adaptability and economy.

[0061] Figure 3 These are structural schematic diagrams of some embodiments of the tunnel maintenance equipment 4 of the maintenance vehicle according to this disclosure, with reference to... Figures 1-3 In some embodiments, the position adjustment device 6 includes a bracket 61 and a pitch mechanism 62. The bracket 61 is connected to the atomizing device 5, and the pitch mechanism 62 is disposed at the bottom of the bracket 61 and connected to the top surface of the water tank 2, and is configured to make the bracket 61 stand upright or rest against the top surface of the water tank 2 relative to the top surface of the water tank 2.

[0062] In this embodiment, the atomizing device 5 can be adjusted in position by setting the bracket 61, and the pitching mechanism 62 can switch the tunnel maintenance equipment 4 between working state and storage state by pitching action. This does not affect the road transportation of the maintenance vehicle, and also allows the maintenance vehicle to be equipped with road dust removal and watering device. It has high utilization rate and adaptability, and can save equipment purchase cost.

[0063] refer to Figures 1-3 In some embodiments, the position adjustment device 6 further includes a slide rail 63 and a base 64. The slide rail 63 is disposed on the top surface of the water tank 2 and parallel to the length direction of the water tank 2. The base 64 is hinged to the bottom of the pitch mechanism 62 and slidably connected to the slide rail 63.

[0064] In this embodiment, by setting the slide rail 63 and the base 64, the tunnel maintenance equipment 4 can move horizontally on the top surface of the water tank 2. Without moving the vehicle body 1, the tunnel maintenance equipment 4 can achieve uniform atomized spraying within a certain distance range through reciprocating motion on the top surface of the water tank 2.

[0065] refer to Figure 3 In some embodiments, the position adjustment device 6 further includes a vertical movement mechanism 65 disposed on the outside of the bracket 61 and configured to move vertically relative to the bracket 61 to adjust the height of the atomizing device 5. The vertical movement mechanism 65 includes, but is not limited to, extending and retracting relative to the bracket 61 via an internal hydraulic cylinder.

[0066] In this embodiment, a vertical moving mechanism 65 is provided so that the atomizing device 5 can move up and down with the movement of the vertical moving mechanism 65, which can be adjusted accordingly for tunnels of different heights and has good adaptability.

[0067] refer to Figure 3In some embodiments, the vertical moving mechanism 65 includes a first vertical moving member 651, a second vertical moving member 652, and a third vertical moving member 653, which are arranged sequentially along the width direction of the water tank 2.

[0068] In this embodiment, three vertical moving parts can be arranged side by side, and an atomizing device 6 is provided on each vertical moving part. The movement of the atomizing devices 6 connected to different vertical moving parts is independent of each other, so that the movement of the atomizing devices 6 can have a higher degree of freedom, can achieve a larger spraying area, make the atomization maintenance effect of the tunnel more uniform, and help improve the efficiency of lining maintenance.

[0069] refer to Figure 3 In some embodiments, the position adjustment device 6 further includes: a plurality of horizontal moving mechanisms 66 located on both sides of the bracket 61 relative to the vehicle body 1, and connected to the first vertical moving member 651 and the third vertical moving member 653 respectively. The horizontal moving mechanisms 66 are configured to adjust the lateral distance of at least a portion of the atomizing device 5 relative to the bracket 61.

[0070] In this embodiment, by setting the horizontal moving mechanism 66 to be connected to the first vertical moving member 651 and the third vertical moving member 653 respectively, the atomizing device 6 can extend and retract horizontally on the basis of vertical movement, so as to adapt well to different distances between the vehicle body 1 and the tunnel wall, and has a wide range of applications. Moreover, during the atomization maintenance process, only the vertical moving mechanism 65 and / or the horizontal moving mechanism 66 need to be adjusted to achieve uniform and fine spraying of the atomizing device 6 onto the tunnel wall, without the need to control the vehicle body 1 to perform too many turning operations, and can also significantly improve the efficiency and accuracy of lining maintenance. The horizontal moving mechanism 66 includes, but is not limited to, extending and retracting relative to the bracket 61 through an internal hydraulic cylinder.

[0071] refer to Figure 3 In some embodiments, at least two of the multiple horizontal moving mechanisms 66 are located on the same side of the support 61, and the horizontal moving mechanisms 66 located on the same side of the support 61 are spaced apart along the length of the support 61 and are parallel to each other. In this embodiment, at least two horizontal moving mechanisms 66 can be arranged on the same side of the support 61, thereby increasing the range of atomized curing and improving the efficiency of lining curing operations.

[0072] refer to Figure 3In some embodiments, the position adjustment device 6 further includes a swing mechanism 67, disposed on both sides of the bracket 61 and respectively connected between a horizontal moving mechanism 66 and a vertical moving mechanism 65 located on the same side, configured to adjust the angle of at least a portion of the atomizing device 5 relative to the bracket 61. The swing mechanism 67 includes, but is not limited to, extending and retracting relative to the bracket 61 via an internal hydraulic cylinder. The angle of a plurality of parallel horizontal moving mechanisms 66 located on the same side can be adjusted by the swing mechanism 67, thereby allowing the atomizing device 5 to translate in the vertical plane.

[0073] In this embodiment, by setting a swing mechanism 67 between the horizontal moving mechanism 66 and the vertical moving mechanism 65 located on the same side, the angle of the atomizing device 5 can be further adjusted, thereby effectively optimizing the spraying accuracy of the atomizing device 5 and achieving uniform and effective spraying for tunnels of different sizes and different positions on the tunnel wall.

[0074] refer to Figures 1-3 In some embodiments, multiple atomizing devices 5 are provided. A portion of the multiple atomizing devices 5 is connected to a second vertical moving member 652, such as a first atomizing mechanism 51, and another portion of the multiple atomizing devices 5 is connected to horizontal moving mechanisms 66 located on both sides of the support 61, such as a second atomizing mechanism 52. The atomizing devices 5 connected to the second vertical moving member 652 are arranged parallel to the top surface of the water tank 2, while the atomizing devices 5 connected to the horizontal moving mechanisms 66 located on both sides of the support 61 are arranged perpendicular to the top surface of the water tank 2.

[0075] In this embodiment, the first atomizing mechanism 51 is not limited to being T-shaped and having an arc-shaped end to match the contour of the tunnel roof. The top of the second atomizing mechanism 52 can also be set to be an arc-shaped structure tilted at a certain angle toward the support 61 to match the contour of the tunnel sidewall, so that the maintenance vehicle can move flexibly in the tunnel during tunnel maintenance work, avoid scratches, and achieve efficient maintenance.

[0076] Figure 4 These are schematic diagrams of other embodiments of the tunnel maintenance equipment of the maintenance vehicle according to the present disclosure, with reference to... Figure 4 In some embodiments, the atomizing device 5 includes a water pipe 53 and nozzles 54. The water pipe 53 is connected to the water tank 2, and the nozzles 54 are spaced apart on the water pipe 53 and configured to spray water from the water pipe 53. In this embodiment, the atomizing device 5 includes, but is not limited to, the form of a water pipe 53 and nozzles 54, which spray water from the water tank 2 through the water pipe 53 and nozzles 54 to form a water mist that is sprayed onto the inner wall of the tunnel.

[0077] refer to Figure 4In some embodiments, the atomizing device 5 further includes a plate 55 and a fixing member 56. The plate 55 is connected to and disposed around the position adjustment device 6, and the fixing member 56 is configured to secure at least a portion of the water pipe 53 to the edge of the plate 55. In this embodiment, the water pipe 53 and the nozzle 54 can be fixed to a shape adapted to the inner wall of the tunnel by means of the plate 55 and the fixing member 56. The dimensions of the plate 55, the fixing member 56, the water pipe 53, and the nozzle 54 can be adjusted according to different dimensions of the tunnel cross-section.

[0078] In some embodiments, the atomizing device 5 further includes a plurality of control valves connected to the water pipe 53, each control valve being configured to control the on / off state of at least a portion of the water pipe 53. In this embodiment, multiple control valves can be provided to independently control the on / off state of the water pipe 53 on different sides of the bracket 61, thereby improving the operability and flexibility of the atomizing device 5.

[0079] refer to Figure 1 and Figure 2 In some embodiments, the water spraying device 3 includes a dust suppression device 31, which is disposed at the rear of the vehicle body 1. In this embodiment, the dust suppression device 31 can be mounted at the rear of the vehicle body 1 so that the maintenance vehicle can be used to spray water on the road surface to suppress dust during non-tunnel maintenance periods.

[0080] In some embodiments, the dust suppression device 31 includes at least one of a water gun 31a, a shower head 31b, and a fog cannon 31c. In this embodiment, the dust suppression device 31 includes, but is not limited to, a water gun 31a, a shower head 31b, and a fog cannon 31c. The equipment mounted on the vehicle body 1 can be adjusted according to the actual application scenario to adapt to different operational needs.

[0081] refer to Figures 1-2 In the transport or other working states of the maintenance vehicle, the atomizing device 5 is retracted relative to the bracket 61 and placed against the water tank 2 by the position adjustment device 6. In the tunnel maintenance state of the maintenance vehicle, the horizontal movement mechanism 66 can be adjusted first to extend the atomizing device 5 to both sides relative to the bracket 61 to avoid the atomizing device 5 standing up directly and scratching the vehicle body 1 or the water tank 2. After unfolding, the pitching mechanism 62 is used to stand the atomizing device 5 up, and the distance between the atomizing device 5 and the tunnel wall is adjusted according to the tunnel size.

[0082] During spraying and atomization, the opening and closing of the water pipes 53 in the first atomizing mechanism 51 and the second atomizing mechanism 52 can be controlled independently as needed. The maintenance vehicle can move forward at a constant speed during operation. After completing one forward movement, it can reverse to perform another maintenance, and this cycle can be repeated multiple times to complete the maintenance. Alternatively, the vehicle can remain stationary, allowing the support 61 to reciprocate on the slide rail 63. After completing the maintenance for that distance, the maintenance vehicle can move forward a further distance, and the atomizing device 51 can continue to reciprocate relative to the vehicle body 1, repeating this cycle multiple times to complete the maintenance.
