Description

Technical Field

[0001] The present invention relates to the field of tunnels, and particularly to a lightweight assembling device and installation method for steel segment rings of subway tunnels. Background Art

[0002] Tunnel reinforcement is of great significance in the construction of urban subways and transportation infrastructure. Among the existing tunnel reinforcement methods, steel ring reinforcement is a commonly used and effective method.

[0003] Traditional steel segment rings for steel ring reinforcement often have a relatively large weight, exceeding 0.5 to 1.2 tons per segment, which poses difficulties in on-site transportation and installation. To install these heavy steel segment rings, large mechanical equipment is usually required for lifting. After being lifted, a large hydraulic press is needed to press the lifted steel segment ring against the inner wall of the tunnel, which limits the construction flexibility and efficiency. The installation of heavy steel segment rings relies on large equipment, with poor construction flexibility. The deployment of large lifting equipment or large hydraulic press equipment is restricted by the tunnel space. The installation steps are cumbersome and difficult. It is relatively difficult for large equipment to move in the tunnel. At the same time, the debugging of large equipment takes a long time, and the adaptability to construction scenarios is poor.

[0004] The operation process of heavy equipment is complex, requiring multiple hoisting and positioning. The single-ring installation period is long, and the safety risk of multiple hoisting is relatively high. Heavy equipment occupies the track resources for a long time, resulting in low efficiency of multi-disciplinary collaboration.

[0005] Existing steel segment rings are connected to the steel ring through a hydraulic press or fastening equipment. After the steel segment ring is transported to the tunnel wall, the staff needs to move to the vicinity of the steel segment ring to loosen the fastening equipment of the steel segment ring. When the steel segment ring is at a relatively high position on the tunnel wall, the staff needs to reach the operation position by means of equipment such as scaffolding and lifting platforms. The manual operation is difficult, with high safety risks and low construction efficiency. For this reason, we propose a lightweight assembling device and installation method for steel segment rings of subway tunnels to solve the above problems. Summary of the Invention

[0007] Another technical problem solved by the present invention is: when loosening the fastening equipment of the steel segment ring after the steel segment ring is transported to the tunnel wall, the manual operation is difficult, with high safety risks and low construction efficiency.

Specific embodiments

[0022] Embodiment 1: As Figure 1-12In a lightweight assembling device and installation method for subway tunnel steel segment rings, it includes an assembling mechanism 1. The assembling mechanism 1 includes a sliding vehicle 2. A rotating frame 3 is rotatably arranged on the sliding vehicle 2. One end of the rotating frame 3 is provided with a telescopic mechanism 4. A plurality of magnets 5 are arranged on the telescopic mechanism 4. A transmission mechanism 6 is arranged on one side of the sliding vehicle 2. A plurality of steel segment rings 9 are arranged on the sliding vehicle 2. With this structure, when the telescopic mechanism 4 on the rotating frame 3 rotates to the lowest point, the telescopic mechanism 4 slides so that the plurality of magnets 5 abut against the steel segment rings 9. The magnets 5 are electrified, and the plurality of magnets 5 are connected to the steel segment rings 9. The transmission mechanism 6 is driven to make the chain 602 rotate, so that the driven sprocket 604 rotates, so that the rotating shaft 302 rotates relative to the sliding vehicle 2. The rotating wheels 306 at one end of the limiting rod 305 abut against and slide on the limiting ring 307. The two limiting rods 305 are respectively located at both ends of the rotating shaft 302, so that the rotating wheels 306 are respectively located at both ends of the limiting ring 307, forming a symmetrical constraint structure. When one of the rotating wheels is at the top of the limiting ring, the other is at the bottom, and the eccentric moment during the rotation is offset by diagonal bracing, avoiding the shaking or tilting of the rotating frame 3. Especially when carrying heavy steel segment rings 9, the rotation stability is ensured. The rotating wheel 306 rolls in the annular groove 3071. Rolling friction replaces sliding friction, reducing wear and energy loss, making the rotation process smoother, distributing the force of the rotating frame 3 to the main structure of the sliding vehicle 2, and improving the overall rigidity.

[0023] Two transmission shaft rows with inclined central axes are arranged at the bottom of the sliding vehicle 2. The steel segment rings 9 are of an arc structure, so that the arc-shaped steel segment rings 9 abut against the inclined roller shafts 209. The transmission shaft row includes a plurality of rotating roller shafts 209. The structure of the roller shafts 209 is convenient for transporting the steel segment rings 9 to be installed to the bottom of the rotating frame 3. The bracket 207 is installed on one side of the sliding vehicle 2, and the transmission mechanism 6 is installed on the other side of the sliding vehicle 2, so that the rotating frame 3 is installed on one side of the sliding vehicle 2. When the steel segment rings 9 to be installed move from one end of the sliding vehicle 2 to the other end, the steel segment rings 9 are transported to the bottom of the rotating frame 3. The structure of the sliding vehicle 2 is convenient for the magnets 5 at the end of the rotating frame 3 to absorb.

[0024] The sleeve 304 is hollow. The telescopic mechanism 4 includes a plurality of sliding rods 401. The sliding rods 401 telescope relative to the sleeve 304, so that the telescopic mechanism 4 telescopes relative to the rotating frame 3, so that the overall mechanism can contact the steel segment rings 9 or can rotate and telescope the steel segment rings 9 to any position on the tunnel wall 10.

[0025] The overall structure sucks the steel ring piece 9 through multiple magnets 5 at one end of the rotating frame 3, avoiding the use of mechanical clamping fixtures such as bolts required for the installation of traditional steel ring pieces. Thus, after the steel ring piece 9 is attached to the tunnel wall 10, the situation where workers need to reach the operation position with the help of equipment such as scaffolding and lifting platforms is avoided. Moreover, the phenomena of high operation complexity, high safety risks, and low construction efficiency when the steel ring piece 9 is separated from the fastening equipment are avoided, greatly improving the work efficiency.

[0026] The rotating frame 3 and the telescopic mechanism 4 rotate relative to the sliding vehicle 2, rotating around the center of the limit ring 307 installed on the sliding vehicle 2, so that the overall structure can adapt to the tunnel space. The rollers 202 of the sliding vehicle 2 abut against the support platform 11 and slide, and the side wheels 203 abut against the slide rail 12 and slide, enabling the overall structure to install the steel ring piece 9 at more positions on the tunnel wall 10, significantly enhancing the flexibility and coverage of the steel ring piece installation.

[0027] The overall structure does not need to be lifted by large mechanical equipment, improving the construction flexibility and efficiency. It can better adapt to the tunnel space, with simple and efficient installation steps, avoiding the phenomena of difficult movement of large equipment in the tunnel and long debugging time. At the same time, it avoids the phenomena of complex operation processes of heavy equipment, requiring multiple hoistings and positioning, long single-ring installation cycle, high hoisting safety risks, and long-term occupation of track resources by heavy equipment.

[0028] In a preferred solution, the sliding vehicle 2 includes a bracket 207. A base 201 is provided at the bottom of the bracket 207. Multiple rollers 202 and multiple side wheels 203 are provided on the base 201. A housing 204 is provided on the base 201.

[0029] In a preferred solution, inclined slots 205 are provided on both sides of the housing 204. Support rods are provided on the inclined slots 205, and multiple first counterweight blocks 7 are provided on the support rods. Multiple second rotating seats 208 are provided at the top of the bracket 207. With this structure, multiple first counterweight blocks 7 are placed on both sides of the sliding vehicle 2 to make the sliding vehicle 2 stable. When the rotating frame 3 is connected to the steel ring piece 9 and the rotating frame 3 rotates, the telescopic mechanism 4 can extend and retract arbitrarily, and the center of gravity position of the rotating frame 3 and the steel ring piece 9 changes. With multiple first counterweight blocks 7 on both sides of the sliding vehicle 2, the phenomenon of the sliding vehicle 2 tipping over when the center of gravity position of the rotating frame 3 and the steel ring piece 9 changes is avoided. The inclined slots 205 are inclined relative to the sliding vehicle 2, preventing the support rods from falling off the sliding vehicle 2 during the movement of the sliding vehicle 2.

[0030] One end of the rotating frame 3 is equipped with a plurality of second counterweight blocks 8. When the rotating frame 3 and the steel ring plate 9 rotate, it can prevent the end of the rotating frame 3 with the steel ring plate 9 from being heavier and affecting the overall balance, so as to balance the self-weight of the steel ring plate 9, facilitate the assembly operation of the equipment, and further avoid the tipping of the sliding vehicle 2. The plurality of second counterweight blocks 8 are installed on the mounting shaft 303. When the type of the steel ring plate 9 changes to adapt to the tunnel wall 10 at different positions and the weight of the steel ring plate 9 changes, the weight on the mounting shaft 303 is changed to ensure that the rotating frame 3 will not tip over during rotation.

[0031] At the same time, the second counterweight block 8 has the same structure as the first counterweight block 7. The first counterweight block 7 can be taken from the inclined groove 205 and installed on the mounting shaft 303 as the second counterweight block, which is convenient for increasing and decreasing the number of the second counterweight blocks 8 on the rotating frame 3.

[0032] In a preferred solution, there are two rows of transmission shaft rows inclined towards the central axis of the bracket 207 on the bracket 207. The transmission shaft row includes a plurality of rollers 209. There are a plurality of rotating seats 206 on the bracket 207. The rollers 209 are rotatably connected to the rotating seats 206. A plurality of arc-shaped steel ring plates 9 are abutted against the rollers 209 and roll. With this structure, there are two rows of transmission shaft rows with inclined central axes at the bottom of the sliding vehicle 2, and the steel ring plate 9 is of an arc structure, so that the arc-shaped steel ring plate 9 abuts against the inclined rollers 209. The transmission shaft row includes a plurality of rotating rollers 209. The structure of the rollers 209 is convenient for transporting the steel ring plate 9 to be installed to the bottom of the rotating frame 3. The bracket 207 is installed on one side of the sliding vehicle 2, and the transmission mechanism 6 is installed on the other side of the sliding vehicle 2, so that the rotating frame 3 is installed on one side of the sliding vehicle 2. When the steel ring plate 9 to be installed moves from one end of the sliding vehicle 2 to the other end, the steel ring plate 9 is transported to the bottom of the rotating frame 3, and the structure of the sliding vehicle 2 is convenient for the magnet 5 at the end of the rotating frame 3 to absorb.

[0033] In a preferred solution, the rotating frame 3 includes a frame body 301. A rotating shaft 302 is provided on the frame body 301. The rotating shaft 302 is connected to the second rotating seat 208. A plurality of hollow sleeves 304 are provided at one end of the frame body 301, and a plurality of mounting shafts 303 are provided at the bottom of the frame body 301. With this structure, the sleeve 304 is hollow. The telescopic mechanism 4 includes a plurality of sliding rods 401. The sliding rods 401 telescope relative to the sleeve 304, so that the telescopic mechanism 4 telescopes relative to the rotating frame 3, so that the overall mechanism can contact the steel ring plate 9 or can rotate and telescope the steel ring plate 9 to any position on the tunnel wall 10.

[0034] In a preferred embodiment, a plurality of second mating blocks 8 are provided on the mounting shaft 303. One end of the mounting shaft 303 is connected to a nut. Limit rods 305 and limit rings 307 are provided on both sides of the frame body 301. A ring groove 3071 is provided on the limit ring 307. A runner 306 is provided at one end of the limit rod 305. The runner 306 abuts against the ring groove 3071 and rolls thereon. The limit ring 307 is mounted on the sliding vehicle 2. With this structure, the sprocket 604 rotates to cause the rotating shaft 302 to rotate relative to the sliding vehicle 2. The runner 306 at one end of the limit rod 305 abuts against the limit ring 307 and slides thereon. The two limit rods 305 are respectively located at both ends of the rotating shaft 302, so that the runners 306 are respectively located at both ends of the limit ring 307.

[0035] When one of the runners 306 is located at the top end of the limit ring 307, the other runner 306 is located at the bottom end of the other limit ring 307, with double-point symmetric limiting, so that the rotating frame 3 rotates more smoothly.

[0036] The limiting mechanism realizes stable support in the limited tunnel space through the radially arranged limit ring 307 and the axially arranged limit rod 305, avoiding the use of a large-volume support structure, which meets the requirements of subway tunnel construction for space compactness.

[0037] In a preferred embodiment, the telescopic mechanism 4 includes a plurality of slide rods 401. A connecting plate 402 is provided at one end of the plurality of slide rods 401. The magnet 5 is mounted on the connecting plate 402. The slide rods 401 abut against the sleeve 304 and slide thereon. A cylinder is provided between the slide rods 401 and the sleeve 304. With this structure, the overall structure sucks the steel ring segments 9 through the plurality of magnets 5 at one end of the rotating frame 3, avoiding the use of mechanical clamping and fixing such as bolts and clamps required for the installation of traditional steel ring segments. Thus, after the steel ring segments 9 are attached to the tunnel wall 10, the phenomenon that workers need to reach the operation position by means of equipment such as scaffolding and lifting platforms is avoided. Therefore, the phenomenon of high operation complexity, high safety risk and low construction efficiency when the steel ring segments 9 are separated from the fastening equipment is avoided, greatly improving the work efficiency.

[0038] In a preferred embodiment, the transmission mechanism 6 includes a motor 601. A main sprocket 603 is provided on the output shaft of the motor 601. A chain 602 is provided on the main sprocket 603 and meshes therewith. A slave sprocket 604 is provided on the chain 602. The slave sprocket 604 is connected to the rotating shaft 302. The motor 601 is mounted on the sliding vehicle 2. With this structure, the driving motor 601 is driven to cause the main sprocket 603 to rotate, causing the chain 602 to rotate, causing the slave sprocket 604 to rotate, and causing the rotating frame 3 to rotate.

[0039] In a preferred embodiment, a support platform 11 is provided at the bottom of the tunnel wall 10. A plurality of slide rails 12 are provided on the support platform 11. The rollers 202 are abutted against the support platform 11, and the side wheels 203 are abutted against the slide rails 12. A plurality of through holes 901 are provided on the steel ring segment 9, and the steel ring segment 9 is abutted against the tunnel wall 10. With this structure, the rotating frame 3 and the telescopic mechanism 4 rotate relative to the sliding vehicle 2, rotating around the center of the limit ring 307 mounted on the sliding vehicle 2, so that the overall structure can adapt to the tunnel space. The rollers 202 of the sliding vehicle 2 slide while abutted against the support platform 11, and the side wheels 203 slide while abutted against the slide rails 12, so that the overall structure can install the steel ring segment 9 at more positions on the tunnel wall 10, significantly improving the flexibility and coverage range of the installation of the steel ring segment.
