Description

Technical Field

[0001] This invention relates to the field of tunnel lining construction technology, specifically to a tunnel lining construction device. Background Technology

[0002] Constructing gas storage facilities in abandoned mine shafts or artificially excavated caverns is a common cavern renovation scheme. This involves using steel lining plates to build circular internal gas storage facilities in lined caverns for storing hydrogen, natural gas, helium, air, etc.

[0003] To improve the structural stability and sealing of caverns, it is necessary to assemble linings on the inner walls. In the construction of abandoned mines and manually excavated caverns using a modular assembly method, the limited cross-sectional dimensions of typical abandoned mines prevent many large construction machines from operating inside, leading to difficulties in the assembly of the lining panels. Currently, in many projects, the installation of steel lining panels still relies on transport trolleys and winches for hoisting. While this method solves the problem of hoisting and transporting the steel lining panels, it still requires the use of internal construction support frames during subsequent concrete pouring to prevent deformation of the steel lining. Existing support frames can be found in patent application number CN201910739586.6, but the erection and dismantling of these support frames is extremely cumbersome, resulting in low efficiency in the lining construction.

[0004] Therefore, how to quickly construct the supporting structure for the lining is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a construction device for cave lining, which solves the technical problem of how to quickly build the supporting structure for lining in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This invention provides a construction device for lining caves, comprising:

[0008] Base frame;

[0009] A movable component, which is drively connected to the base frame and is capable of moving the base frame in three-dimensional space; and

[0010] A plurality of support components are arranged circumferentially along the base frame. Each support component includes a folding frame, a liner, and a folding drive. One end of the folding frame is connected to the base frame, and the other end is connected to the liner. The folding frame has an extended state that moves the liner away from the base frame and a retracted state that moves the liner close to the base frame. The folding drive drives the folding frame to switch between the extended state and the retracted state.

[0011] In some embodiments, the moving component includes a moving trolley, a slide, a translation drive, a lifting seat, and a lifting drive. The moving trolley is capable of horizontal movement. The slide is slidably disposed on the trolley in a horizontal direction, and its direction of movement is perpendicular to the direction of movement of the trolley. The lifting seat is slidably disposed on the slide in a vertical direction. The lifting drive is throttle-connected to the lifting seat to drive the lifting seat to slide relative to the slide. The base frame is mounted on the lifting seat.

[0012] In some embodiments, the support assembly further includes a flipping drive, one end of the base frame is rotatably mounted on the slide, and the flipping drive is connected to the base frame to drive the base frame to rotate relative to the slide.

[0013] In some embodiments, the tilting drive includes a tilting cylinder, the cylinder body of which is hinged to the slide block, and the piston rod of the tilting tank is hinged to the base frame.

[0014] In some embodiments, the mobile trolley is provided with a toothed track, and the translation drive includes a first motor and a drive gear. The drive gear is rotatably mounted on a slide and meshes with the toothed track, and the first motor drives the drive gear to rotate.

[0015] In some embodiments, the slide has a guide groove in the vertical direction, the lifting seat is slidably disposed in the guide groove, the lifting drive includes a lifting cylinder, the cylinder body of the lifting cylinder is connected to the slide, and the piston rod of the lifting cylinder is connected to the lifting seat to push the lifting seat to slide along the guide groove.

[0016] In some embodiments, the mobile trolley includes a vehicle body, a second motor, a drive wheel, and a plurality of driven wheels. The drive wheel and the plurality of driven wheels are rotatably mounted on the vehicle body, and the plurality of driven wheels are connected to the drive wheel via a transmission. The second motor drives the drive wheel to rotate.

[0017] In some embodiments, the moving component further includes a counterweight water tank, which is mounted on the slide, and the counterweight water tank and the lifting seat are respectively located at both ends of the slide.

[0018] A lining support method for the aforementioned tunnel lining construction device, comprising:

[0019] S1. Adjust the support to the construction position;

[0020] S2. Obtain the initial coordinates of the support when it is in the construction position;

[0021] S3, Obtain the real-time load of the supporting element;

[0022] S4. Adjust the support force of the liner according to the real-time load of the liner so that the liner can be stably maintained at the initial coordinates.

[0023] In some embodiments, the real-time load includes the pressure borne by the support and the torque of the support shaft.

[0024] First, all support components are adjusted to their retracted state, bringing the lining close to the base frame. Then, the base frame is moved in three-dimensional space by the moving components, extending it into the cavern. The folding frame is then adjusted to its extended state, moving the lining away from the base frame and closer to the cavern wall. The lining can then be used to support the lining, facilitating cavern lining construction. Using this cavern lining construction device, by switching the state of the folding frame and adjusting the position of the base frame, the support structure for the lining can be quickly erected, thereby improving the efficiency of cavern lining construction.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] To address the technical problem of how to quickly construct the supporting structure for lining, this invention provides a construction device for cave lining, which can quickly construct the supporting structure for lining and improve the work efficiency of cave lining construction.

[0036] It should be noted that the rock lining construction device of the present invention is used for, but not limited to, the reinforcement construction of rock caves. For ease of explanation, this invention will only use the application of the rock lining construction device to the reinforcement construction of rock caves as an example. The principle of the rock lining construction device applied to other types of equipment is essentially the same as that applied to the reinforcement construction of rock caves, and will not be described in detail here.

[0037] Please see Figure 1 , Figure 1 This is a schematic diagram of a cave lining construction device according to an embodiment of the present invention. The cave lining construction device includes a base frame 100, a moving component 200, and several supporting components 300. The moving component 200 is connected to the base frame 100 and can drive the base frame 100 to move in three-dimensional space. Several supporting components 300 are arranged circumferentially along the base frame 100. Each supporting component 300 includes a folding frame 310, a liner 320, and a folding drive component 330. One end of the folding frame 310 is connected to the base frame 100, and the other end is connected to the liner 320. The folding frame 310 has an extended state in which the liner 320 is moved away from the base frame 100, and a retracted state in which the liner 320 is moved close to the base frame 100. The folding drive component 330 drives the folding frame 310 to switch between the extended and retracted states.

[0038] In this embodiment, each support component 300 is first adjusted to a retracted state, so that the liner 320 is close to the base frame 100. Then, the moving component 200 moves the base frame 100 in three-dimensional space, extending the base frame 100 into the cavern. The folding frame 310 is then adjusted to an extended state, so that the liner 320 is moved away from the base frame 100 and closer to the inner wall of the cavern. The liner 320 can then be used to support the lining, facilitating cavern lining construction. By switching the state of the folding frame 310 and adjusting the position of the base frame 100 using the above-described cavern lining construction device, the support structure for the lining can be quickly erected, thereby improving the work efficiency of cavern lining construction.

[0039] See also Figures 1 to 4 In some embodiments, the moving component 200 includes a moving trolley 210, a slide 220, a translation drive 230, a lifting seat 240, and a lifting drive 250. The moving trolley 210 can move horizontally. The slide 220 is slidably disposed on the trolley in a horizontal direction, and its direction of movement is perpendicular to the direction of movement of the trolley. The lifting seat 240 is slidably disposed on the slide 220 in a vertical direction. The lifting drive 250 is connected to the lifting seat 240 to drive the lifting seat 240 to slide relative to the slide 220. The base frame 100 is mounted on the lifting seat 240.

[0040] In this embodiment, the trolley 210 moves horizontally, the slide 220 slides horizontally relative to the trolley, and the lifting seat 240 can slide vertically. By adjusting the positions of the trolley 210, the slide 220, and the lifting seat 240, the base frame 100 can be moved in three-dimensional space. This, in turn, moves the base frame 100 within the cave, thereby causing the folding frame 310 to reach a predetermined position.

[0041] It should be noted that the folding frame 310 includes several joints, each joint including two connecting rods 311 that are hinged to each other in the middle, and the ends of the connecting rods 311 of adjacent joints are hinged to each other. The joints are connected in series to form the folding frame 310. If the two connecting rods 311 of any joint rotate relative to each other, all connecting rods 311 can be rotated, thereby changing the total length of the folding frame 310.

[0042] It should be noted that the connecting rods 311 at both ends of the folding frame 310 need to be connected to the base frame 100 and the support 320 respectively. The base frame 100 has a guide rod 110. One of the connecting rods 311 connected to the base frame 100 is directly hinged to the guide rod 110, and the other connecting rod 311 connected to the base frame 100 is hinged to a sliding sleeve 312, which is fitted onto the guide rod 110. One of the connecting rods 311 connected to the support 320 has its end hinged to the support 320. The support 320 has a connecting groove 321, and the other connecting rod 311 connected to the support 320 has its end hinged to the connecting groove 321.

[0043] See also Figure 3 , Figure 4 and Figure 6 Based on the above embodiments, in some embodiments, the support assembly 300 further includes a flipping drive 340. One end of the base frame 100 is rotatably mounted on the lifting seat 240. The flipping drive 340 is connected to the base frame 100 to drive the base frame 100 to rotate relative to the lifting seat 240.

[0044] In this embodiment, the flipping drive 340 drives the base frame 100 to rotate relative to the lifting seat 240, thereby adjusting the tilt angle of the base frame 100, and then adjusting the tilt angle of the folding frame 310 and the liner 320, so that the lining supported by the liner 320 can fit into the inner wall of the cave.

[0045] Any implementation of the flipping drive 340 that can drive the base frame 100 to rotate relative to the lifting seat 240 is feasible. In some embodiments, the flipping drive 340 includes a flipping cylinder 341, the cylinder body of the flipping cylinder 341 is hinged to the slide 220, and the piston rod of the flipping oil tank is hinged to the base frame 100.

[0046] In this embodiment, the piston rod of the tilting cylinder 341 slides relative to the cylinder body of the tilting cylinder 341, thereby driving the base frame 100 to rotate relative to the lifting seat 240.

[0047] In some embodiments, the mobile trolley 210 is provided with a toothed track 2111, and the translation drive 230 includes a first motor 231 and a drive gear 232. The drive gear 232 is rotatably mounted on the slide 220 and meshes with the toothed track 2111. The first motor 231 drives the drive gear 232 to rotate.

[0048] In this embodiment, the first motor 231 drives the drive gear 232 to rotate. Since the drive gear 232 and the toothed track 2111 mesh with each other, the slide 220 can be moved relative to the moving carriage 210. In addition, since the drive gear 232 and the toothed track 2111 cooperate with each other, the drive gear 232 will not slip relative to the toothed track 2111, and the translation distance of the slide 220 relative to the carriage can be precisely controlled.

[0049] In some embodiments, the slide 220 has a guide groove 221 in the vertical direction, the lifting seat 240 is slidably disposed in the guide groove 221, and the lifting drive 250 includes a lifting cylinder 251. The cylinder body of the lifting cylinder 251 is connected to the slide 220, and the piston rod of the lifting cylinder 251 is connected to the lifting seat 240 to push the lifting seat 240 to slide along the guide groove 221.

[0050] In this embodiment, under the guidance and limiting effect of the guide groove 221, the lifting seat 240 has a stable sliding trajectory. The lifting cylinder 251 pushes the lifting seat 240 to slide along the guide groove 221, thereby driving the lifting seat 240 to slide in the vertical direction.

[0051] Based on the above embodiments, in a more specific embodiment, the slide 220 has two oppositely arranged guide grooves 221, and the two ends of the lifting seat 240 are respectively slidably embedded in the two guide grooves 221. Since the two ends of the guide grooves 221 cooperate with the two guide grooves 221 respectively, the lifting seat 240 can be prevented from deflecting during the sliding process.

[0052] In some embodiments, the slide 220 has multiple guide wheels 222, and the trolley 210 also has multiple guide rails 2112. Every two guide wheels 222 are mounted on both sides of a guide rail 2112. The guide wheels 222 can not only guide the slide 220, but also prevent the slide 220 from flipping relative to the trolley 210 by clamping the guide rails 2112, thus preventing the slide 220 from tipping over.

[0053] See also Figure 4 In some embodiments, the mobile trolley 210 includes a vehicle body 211, a second motor 212, a drive wheel 213 and a plurality of driven wheels 214. The drive wheel 213 and the plurality of driven wheels 214 are rotatably mounted on the vehicle body 211, and the plurality of driven wheels 214 are connected to the drive wheel 213 in a transmission connection. The second motor 212 drives the drive wheel 213 to rotate.

[0054] In this embodiment, the driving wheel 213 and the driven wheel 214 are used to support the vehicle body 211. The second motor 212 drives the driving wheel 213 to rotate, which in turn drives the vehicle body 211 to move horizontally.

[0055] Understandably, the driving wheel 213 and driven wheel 214 can roll directly on the ground, but considering that the floor of a cave is often uneven, a rail can be laid inside the cave, and the trolley 210 slides along the rail. The rail has an I-shaped cross-section, allowing the driving wheel 213 and driven wheel 214 to be embedded in the grooves on the inner side of the rail. In addition, the driving wheel 213 and driven wheel 214 press against the top and bottom edges of the rail, respectively, which can also prevent the trolley 210 from tipping over relative to the rail.

[0056] See also Figure 8 In some embodiments, the moving component 200 further includes a counterweight water tank 260, which is mounted on the slide 220. The counterweight water tank 260 and the lifting seat 240 are located at opposite ends of the slide 220.

[0057] In this embodiment, the counterweight water tank 260 and the lifting seat 240 are respectively located at both ends of the slide 220. The counterweight water tank 260 can balance the force on both ends of the slide 220 and prevent the lifting seat 240 from tilting towards one end of the slide 220. The greater the load borne by the lifting seat 240, the more water the counterweight water tank 260 needs to be filled in, so as to balance the force on the slide 220.

[0058] In some embodiments, the counterweight water tank 260 has an inlet 261 and an outlet 262. The inlet 261 is used to introduce water into the counterweight water tank 260, and the outlet 262 is used to drain water from the counterweight water tank 260. The moving component 200 also includes a pressure sensor installed at the bottom of the counterweight water tank 260 to detect the water pressure at the bottom of the counterweight water tank 260.

[0059] In this embodiment, the larger the amount of water stored in the counterweight water tank 260, the greater the water pressure at the bottom of the counterweight water tank 260. The pressure sensor detects the water pressure at the bottom of the counterweight water tank 260, and then determines the amount of water stored in the counterweight water tank 260 by the water pressure at the bottom of the counterweight water tank 260.

[0060] See also Figure 7 In some embodiments, the folding drive 330 includes a folding cylinder 331, a cylinder body hinged to a base frame 100, and a piston rod hinged to a folding frame 310.

[0061] In this embodiment, the piston rod of the folding cylinder 331 slides relative to the cylinder body of the folding cylinder 331, thereby driving the folding frame 310 to extend or retract, and ultimately driving the liner 320 to move closer to or away from the base frame 100.

[0062] See again Figure 7 Based on the above embodiments, in some preferred embodiments, the liner 320 is rotatably mounted on the folding frame 310, and the support assembly 300 also has an angle-adjusting cylinder 350. The cylinder body of the angle-adjusting cylinder 350 is hinged to the folding frame 310, and the piston rod of the angle-adjusting cylinder 350 is hinged to the liner 320. The piston rod of the angle-adjusting cylinder 350 can slide relative to the cylinder body of the angle-adjusting cylinder 350 to push the liner 320 to flip, thereby adjusting the angle of the liner 320 so that the liner 320 can fully fit the inner wall of the cave.

[0063] Furthermore, the present invention also provides a lining support method for the aforementioned tunnel lining construction device, comprising:

[0064] S1. Adjust the support to the construction position;

[0065] S2. Obtain the initial coordinates of the support when it is in the construction position;

[0066] S3, Obtain the real-time load of the supporting element;

[0067] S4. Adjust the support force of the liner according to the real-time load of the liner so that the liner can be stably maintained at the initial coordinates.

[0068] It should be noted that the load on the lining is not constant during the lining construction process. The load on the lining will change the position of the lining, which will ultimately affect the construction accuracy of the lining. Detecting the real-time load on the lining and adjusting the support force of the lining according to the real-time load will help maintain the stability of the lining position by balancing the support force and the load borne by the lining.

[0069] Based on the above embodiments, in some of these embodiments, the real-time load includes the pressure borne by the support and the torque of the support shaft.

[0070] Understandably, a pressure sensor of appropriate specifications can be used to detect the pressure borne by the liner, and a torque sensor of appropriate specifications can be used to detect the torque of the liner shaft.

[0071] To better understand this invention, the following is combined with... Figures 1 to 8 The technical solution of the present invention will be described in detail below:

[0072] The rock cave lining construction device of the present invention is a construction device used in the construction of rock cave gas storage facilities and tunnels in abandoned mines and artificially excavated caverns. It is used to construct circular internal cavity gas storage facilities and tunnels in rock caves for storing hydrogen, natural gas, helium, air, etc. by means of steel lining sheets.

[0073] When using the cave lining construction device, the piston rod of the folding cylinder 331 slides relative to the cylinder body, causing the folding frame 310 to retract, which in turn moves the lining support 320 closer to the base frame 100. The second motor 212 drives the drive wheel 213 to rotate, allowing the moving trolley 210 to slide along the rails. The first motor 231 drives the drive gear 232 to rotate; since the drive gear 232 and the toothed track 2111 mesh, the sliding block 220 moves relative to the moving trolley 210. The lifting cylinder 251 pushes the lifting seat 240 to slide along the guide groove 221, causing the lifting seat 240 to slide vertically. Ultimately, the moving component 200 moves the base frame 100 in three-dimensional space, allowing the base frame 100 to extend into the cave. After the base frame 100 is positioned, the piston rod of the folding cylinder 331 slides relative to the cylinder body, thereby extending the folding frame 310 and moving the liner 320 away from the base frame 100, bringing the liner 320 closer to the inner wall of the cavern. The liner 320 can then support the lining, facilitating cavern lining construction. By switching the state of the folding frame 310 and adjusting the position of the base frame 100, the aforementioned cavern lining construction device allows for the rapid erection of the lining support structure, thus improving the efficiency of cavern lining construction.

[0074] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
