Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] The core of this invention is to provide a contour-following spray curing trolley that can adapt to different tunnels.

[0048] Please refer to Figures 1-6 , Figure 1 This is a top view of the contour spraying and curing trolley provided in a specific embodiment of the present invention; Figure 2 This is the front view of the contour spray curing trolley; Figure 3 A schematic diagram of the structure when the contour-following main support, the first contour-following rod, and the second contour-following rod are unfolded and raised; Figure 4 for Figure 3A magnified view of part A in the image; Figure 5 for Figure 3 Another structural diagram from a different perspective; Figure 6 A schematic diagram of the contour spray curing trolley in operation.

[0049] This invention provides a contour spraying maintenance trolley, including a contour main support 101, a first contour rod 102, a second contour rod 103, an unfolding cylinder 105, a boom assembly 200, a turntable device 300, and a dismounting device 400. Specifically, the first contouring rod 102 and the second contouring rod 103 are each provided with a plurality of nozzles 104, which are used to spray the tunnel secondary lining surface; the first contouring rod 102 and the second contouring rod 103 are respectively hinged to the two ends of the contouring main support bracket 101; the deployment cylinder 105 is connected to the first contouring rod 102, the second contouring rod 103 and the contouring main support bracket 101 respectively, and is used to adjust the deployment angle of the first contouring rod 102 and the second contouring rod 103; the contouring main support bracket 101 is connected to the boom assembly 200 so that the height of the contouring main support bracket 101 can be adjusted through the boom assembly 200; the boom assembly 200 is mounted on the turntable device 300, which is rotatably mounted on the dismount device 400, and the dismount device 400 is used to travel in the tunnel.

[0050] During operation, the hydraulic cylinder 105 is used to drive the first contouring rod 102 and the second contouring rod 103 to rotate relative to the contouring main support 101, so that the first contouring rod 102 and the second contouring rod 103 are extended to a suitable angle. The boom assembly 200 is used to drive the contouring main support 101 to lift the first contouring rod 102 and the second contouring rod 103 together. The turntable device 300 can also be used to rotate the boom assembly 200 to rotate the contouring main support 101, the first contouring rod 102 and the second contouring rod 103 together to a suitable angle. Finally, the first contouring rod 102 and the second contouring rod 103 are made to be approximately parallel to the tunnel cross-section. Then, spray water is supplied to the nozzle 104 to spray the water more evenly on the concrete, so as to better protect the tunnel secondary lining.

[0051] As can be seen, the contour spraying maintenance trolley provided in this embodiment can automatically perform spraying maintenance on the tunnel secondary lining when the undercarriage device 400 is traveling, replacing manual operation. This reduces labor intensity and improves work efficiency. Furthermore, during maintenance, the deployment angle and spraying height of the first contouring rod 102 and the second contouring rod 103 can be automatically adjusted according to different tunnels, allowing operation in various tunnels. Moreover, when encountering complex vehicle conditions during tunnel maintenance, the first contouring rod 102 and the second contouring rod 103 can be retracted to an undeployed state to allow the vehicle to pass, demonstrating good flexibility.

[0052] Those skilled in the art will understand that the shapes of the contoured main support 101, the first contoured rod 102, and the second contoured rod 103 are similar to the shape of the tunnel cross section, and are arc-shaped.

[0053] In this embodiment, the first contour rod 102 and the second contour rod 103 can each be a single integral arc-shaped rod.

[0054] To better adapt to the shape of the tunnel, in some embodiments, at least one of the first contouring rod 102 and the second contouring rod 103 includes at least two contouring rod segments 1021, with adjacent contouring rod segments 1021 hinged together, and one end of the contouring rod segment 1021 hinged to the contouring main support bracket 101. That is, in this embodiment, the first contouring rod 102 or the second contouring rod 103 is formed by sequentially hinged two or more contouring rod segments 1021. In this way, the angle between adjacent contouring rod segments 1021 can be adjusted, thus allowing the shape of the first contouring rod 102 or the second contouring rod 103 to be locally adjusted to better adapt to tunnels of different shapes and improve the spraying effect.

[0055] Furthermore, after the angle between two adjacent contoured rod segments 1021 is adjusted to the correct position, in order to prevent the relative position between the two adjacent contoured rod segments 1021 from changing during the spraying process, in some embodiments, a limiting screw 106 is connected between the two adjacent contoured rod segments 1021. At least one of the two adjacent contoured rod segments 1021 is slidably connected to the limiting screw 106. The limiting screw 106 is provided with a locking nut for locking the two adjacent contoured rod segments 1021 after the angle between the two adjacent contoured rod segments 1021 is adjusted to the correct position. In other words, when it is necessary to adjust the angle between two adjacent contoured rod segments 1021, one of the contoured rod segments 1021 is rotated relative to the other. During this process, at least one of the two adjacent contoured rod segments 1021 slides relative to the limiting screw 106. After the angle between the two adjacent contoured rod segments 1021 is adjusted to the correct position, the locking nut on the limiting screw 106 is tightened to fix the two adjacent contoured rod segments 1021 to the limiting screw 106, so as to keep the relative position between the two adjacent contoured rod segments 1021 fixed.

[0056] In some embodiments, the number of locking nuts is three, with two locking nuts located on both sides of one of the contour rod segments 1021. When the two locking nuts are screwed into contact with the contour rod segment 1021, one contour rod segment 1021 can be locked. The other locking nut is located on one side of another contour rod segment 1021 and works together with the nut of the limiting screw 106 to lock the other contour rod segment 1021. That is, in this embodiment, the fixing of the limiting screw 106 to two adjacent contour rod segments 1021 can be achieved by using the nut of the limiting screw 106 and three locking nuts.

[0057] In some embodiments, any two adjacent contoured rod segments 1021 are each provided with a rotatable support pin. The support pin has a through hole, and a limiting screw 106 passes through the through hole of the support pin in the two adjacent contoured rod segments 1021. In this embodiment, by rotating the support pin, the through holes of the support pins on the two adjacent contoured rod segments 1021 are aligned with each other, facilitating the installation of the limiting screw 106 and ensuring smooth adjustment of the relative position of the two adjacent contoured rod segments 1021.

[0058] Considering the simplicity of the structure and the ease of installation, in some embodiments, the first contouring rod 102 and the second contouring rod 103 are symmetrically arranged about the center line of the contouring main support bracket 101.

[0059] Furthermore, in the above embodiments, the specific arrangement of the unfolding cylinder 105 is not limited. For example, in some embodiments, there are two unfolding cylinders 105, one of which is hinged to the contouring main support bracket 101 and the first contouring rod 102, and the other is hinged to the contouring main support bracket 101 and the second contouring rod 103, so that the unfolding or retraction of the first contouring rod 102 and the second contouring rod 103 can be controlled by the two unfolding cylinders 105 respectively.

[0060] To achieve synchronized movement of the first contouring rod 102 and the second contouring rod 103, and considering ease of control, in some embodiments, the deployment cylinder 105 is fixed to the contouring main support bracket 101. The piston rod of the deployment cylinder 105 is hinged to the first contouring rod 102 and the second contouring rod 103 respectively via two support rods 107. That is, when the deployment cylinder 105 is activated, the piston rod of the deployment cylinder 105 drives the two support rods 107 to move synchronously, thereby causing the two support rods 107 to drive the first contouring rod 102 and the second contouring rod 103 to move synchronously. The structure is simple and the control is convenient.

[0061] In addition, in order to facilitate the supply of spray water to the nozzle 104, in some embodiments, the contoured main support bracket 101, the first contoured rod 102 and the second contoured rod 103 are all tubular parts for water passage; that is, the contoured main support bracket 101, the first contoured rod 102 and the second contoured rod 103 are used as water pipes to supply spray water to the nozzle 104.

[0062] In other embodiments, the contoured main support bracket 101, the first contoured rod 102, and the second contoured rod 103 are wound around a water pipe, which is connected to each nozzle 104. That is, the contoured main support bracket 101, the first contoured rod 102, and the second contoured rod 103 support the water pipe and supply spray water to the nozzles 104 through a dedicated water pipe.

[0063] To ensure that the contouring main support 101, the first contouring rod 102, and the second contouring rod 103 are at appropriate distances from the tunnel lining, in some embodiments, the contouring main support 101, the first contouring rod 102, and the second contouring rod 103 are each equipped with a first displacement sensor 108. That is, this embodiment uses the first displacement sensor 108 to sense the distances between the contouring main support 101, the first contouring rod 102, and the second contouring rod 103 and the tunnel lining, respectively. Based on the sensing data from the first displacement sensor 108, the deployment angles of the first contouring rod 102 and the second contouring rod 103, as well as the height of the contouring main support 101, are adjusted to ensure that the contouring main support 101, the first contouring rod 102, and the second contouring rod 103 are at appropriate distances from the tunnel lining, ensuring that the contouring spraying maintenance trolley always travels within the set margin in automatic driving mode.

[0064] In addition, in some embodiments, the contoured main support 101, the first contoured rod 102, and the second contoured rod 103 are each equipped with a temperature sensor 109. That is, in this embodiment, the temperature sensor 109 is used to sense the temperature of the tunnel secondary lining so as to determine the temperature of the spray water based on the temperature of the tunnel secondary lining, thereby improving the spray curing effect.

[0065] Furthermore, in some embodiments, the turntable device 300 is equipped with a second displacement sensor 301 to sense obstacles. That is, this embodiment uses the sensing data of the second displacement sensor 301 to control the movement of the contour spraying and curing trolley so that it can stop when it encounters an obstacle and avoid collision accidents.

[0066] To facilitate the supply of spray water to the nozzles 104, in some embodiments, the turntable device 300 is equipped with a water tank 302, which is equipped with a heating device. That is, in this embodiment, the water tank 302, which serves as the water source, is located in the turntable device 300, and the water tank 302 can replace the counterweight of the turntable device 300; in addition, in this embodiment, the heating device is used to heat the water in the water tank 302 so that the temperature of the spray water corresponds to the temperature of the tunnel secondary lining, thereby improving the spray curing effect.

[0067] In addition, to facilitate adjustment of the contouring main support bracket 101, in some embodiments, the contouring main support bracket 101 is hinged to the boom assembly 200, and a first luffing cylinder 211 is also included, which is hinged to both the contouring main support bracket 101 and the boom assembly 200. That is, in this embodiment, the first luffing cylinder 211 is used to adjust the relative position of the contouring main support bracket 101 and the boom assembly 200, which is beneficial for flexibly adjusting the overall position of the contouring main support bracket 101, the first contouring rod 102, and the second contouring rod 103.

[0068] Furthermore, the above embodiments do not limit the specific structure of the boom assembly 200. In some embodiments, the boom assembly 200 includes a lower tower boom 201, an upper tower boom 203, a first connecting seat 202, a second connecting seat 204, a first folding boom 205, a second folding boom 206, a lifting cylinder 207, a second luffing cylinder 208, a driven leveling cylinder 209, and a third luffing cylinder 210. The lower tower boom 201 is hinged to the turntable device 300 and the first connecting seat 202, respectively. The upper tower boom 203 is hinged to the first connecting seat 202 and the second connecting seat 204, respectively. The first folding boom 205 is hinged to the second connecting seat 206, respectively. The connecting seat 204 and the second folding arm 206 are hinged together; the second folding arm 206 is hinged together with the first folding arm 205 and the contoured main support bracket 101 respectively; the lifting cylinder 207 is hinged together with the lower tower arm 201 and the upper tower arm 203 respectively; the second luffing cylinder 208 is hinged together with the second connecting seat 204 and the first folding arm 205 respectively; the driven leveling cylinder 209 is hinged together with the second connecting seat 204 and the first folding arm 205 respectively, and the driven leveling cylinder 209 is linked with the first luffing cylinder 211 to perform compensation operation on the first luffing cylinder 211; the third luffing cylinder 210 is hinged together with the first folding arm 205 and the second folding arm 206 respectively.

[0069] During operation, the lifting cylinder 207, the second luffing cylinder 208, the third luffing cylinder 210, and the first luffing cylinder 211 can raise the contouring main support 101, the first contouring rod 102, and the second contouring rod 103. In addition, when the driven leveling cylinder 209 is passively activated, it performs compensation work on the first luffing cylinder 211, which helps to keep the first luffing cylinder 211 within a stable range.

[0070] In some embodiments, the rod-side chamber of the driven leveling cylinder 209 is connected to the rod-side chamber of the first luffing cylinder 211, and the rodless chamber of the driven leveling cylinder 209 is connected to the rodless chamber of the first luffing cylinder 211. Thus, when the driven leveling cylinder 209 extends, the first luffing cylinder 211 retracts; when the driven leveling cylinder 209 retracts, the first luffing cylinder 211 extends, which helps ensure that the first luffing cylinder 211 remains within a stable range.

[0071] To enhance the structural strength of the boom assembly 200, in some embodiments, the lower tower boom 201 includes a first lower tower boom 2011 and a second lower tower boom 2012; the upper tower boom 203 includes a first upper tower boom 2031 and a second upper tower boom 2032; and the lifting cylinder 207 is hinged to the first lower tower boom 2011 and the second upper tower boom 2032 respectively.

[0072] It should be noted that the specific structure of the disembarkation device 400 is not limited in the above embodiments. In some embodiments, the disembarkation device 400 includes a chassis 401 and battery boxes 403 located on both sides of the chassis 401. The chassis 401 is equipped with a drive motor and a steering axle.

[0073] In addition, the above embodiments do not limit the specific connection method between the turntable device 300 and the unloading device 400. In some embodiments, the turntable device 300 is connected to the unloading device 400 through a slewing support 303, and the slewing support 303 is equipped with a slewing motor.

[0074] It should also be noted that, in this specification, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0075] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0076] The foregoing has provided a detailed description of the contour-following spray curing trolley provided by this invention. Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this invention.
