Description

Technical Field

[0001] This invention relates to the field of tunnel protection technology, specifically to a tunnel construction anti-collapse support device. Background Technology

[0002] During tunnel construction, in order to prevent the tunnel roof from collapsing, support devices are usually used for support and protection, which improve the safety of construction operations and are widely used in the field of tunnel construction.

[0003] In the current technology, the protective device is directly in contact with the top of the tunnel. The vibration caused by the tunnel construction process can cause rocks to fall, which can easily injure workers and pose a safety hazard.

[0004] Therefore, we propose a tunnel construction anti-collapse support device. Summary of the Invention

[0005] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a tunnel construction anti-collapse support device.

A horizontal plate is fixed to the bottom of the vertical plate. The horizontal plate is located at the top of the two sets of support boxes. A material discharge port is opened at the top of the support box and is located on one side of the horizontal plate. It also includes a cylinder, which is fixedly installed inside the support box. The output shaft of the cylinder slides through the top of the support box and is fixedly connected to the bottom of the horizontal plate. It also includes a shaking component, which is installed inside the flow channel. A driving component is installed inside the support box and connected to the shaking component. Finally, it includes a lifting component, which is installed inside the support box and connected to the horizontal plate.

[0007] Furthermore, the shaking component includes an arc-shaped sliding plate and a shock-absorbing spring. The shock-absorbing spring is fixedly distributed at the bottom of the flow channel. The arc-shaped sliding plate is fixedly connected to the top of the shock-absorbing spring, and the sidewalls of the arc-shaped sliding plate slide in contact with the arc-shaped protrusions on both sides. The arc-shaped sliding plate covers the flow channel.

[0008] Furthermore, the drive assembly includes a tension unit, a reciprocating rotation unit, and a pull rope. Two sets of vertical partitions are fixedly installed inside the support box, dividing the support box into a collection chamber, a cylinder chamber, and a drive chamber. The cylinder chamber is located between the collection chamber and the drive chamber, and the cylinder is located inside the cylinder chamber. The material discharge port is located above the collection chamber. The lifting assembly is located inside the collection chamber, and the drive assembly is located inside the drive chamber. The reciprocating rotation unit is located on the bottom wall inside the drive chamber. A connecting plate is fixed between the upper and lower inner walls of the drive chamber. The tension unit is located on the connecting plate. One end of the pull rope is connected to the reciprocating rotation unit, and the other end passes around the tension unit and slides out from the top of the drive chamber before connecting to the arc-shaped sliding plate.

[0009] Furthermore, the reciprocating rotation unit includes a motor, an incomplete gear, a driven gear, and a rope reel. The motor is fixedly mounted on the bottom wall of the inner wall of the drive chamber. The incomplete gear is fixedly mounted on the output shaft of the motor. A central shaft is horizontally connected in series with the center of the driven gear. One end of the central shaft is rotatably mounted on the inner wall of one side of the drive chamber via a bearing. The other end of the central shaft is rotatably mounted on a vertical partition near the drive chamber via a bearing. The driven gear intermittently meshes with the incomplete gear. The rope reel is fixedly mounted on the central shaft. One end of the pull rope is fixedly connected to the rope reel.

[0010] Furthermore, the tension unit includes a mounting plate, a tension wheel, a telescopic rod, a tension spring, and a tension sensor. The telescopic rod is symmetrically fixed on the connecting plate, and the mounting plate is fixed on the end of the telescopic rod away from the connecting plate. The tension sensor is fixed on the connecting plate and located between the two sets of telescopic rods. One end of the tension spring is fixedly connected to one end of the tension sensor, and the other end of the tension spring is fixedly connected to the mounting plate. The tension wheel is rotatably mounted on the mounting plate. The tension unit also includes a guide rope wheel. A second central shaft is horizontally connected to the center of the guide rope wheel. One end of the second central shaft is rotatably mounted on the inner wall of one side of the drive chamber via a bearing, and the other end of the second central shaft is rotatably mounted on a vertical partition near the drive chamber via a bearing. The guide rope wheel is located directly above the winding rope wheel and diagonally above the tension wheel. The other end of the first pull rope passes through the tension wheel and the guide rope wheel in sequence and slides out from the top of the drive chamber, and is fixedly connected to the inner wall of the arc-shaped slide plate.

[0011] Furthermore, a horizontal support is fixed between the two sets of vertical plates, and a fixed pulley is installed on each of the top two sides of the horizontal support. After the pull rope slides out from the top of the drive compartment, it slides through the horizontal support and the arc-shaped support plate, and passes around the fixed pulley. A reinforcing plate is fixed between the horizontal support and the arc-shaped support plate.

[0012] Furthermore, the lifting assembly includes a lifting plate, a load-bearing plate, and a second shock-absorbing spring. The lifting plate is slidably disposed within the collection chamber.

A vertical rod is fixedly provided at the bottom of the horizontal plate and slides through the top of the cylinder chamber. A second pull rope is fixedly connected to the bottom end of the vertical rod. The other end of the second pull rope slides through the top of the cylinder chamber and extends into the collection chamber, and slides through the load-bearing plate and is fixedly connected to the lifting plate.

[0013] Furthermore, a fixed pulley two is installed on the top of the support box. The fixed pulley two is located on one side of the material discharge port. The pull rope two slides through the top of the cylinder chamber and then passes around the fixed pulley two.

[0014] Furthermore, the bottom of the lifting plate is also fixedly provided with a cone-shaped spike, and the bottom of the collection chamber is provided with an avoidance opening for the cone-shaped spike to pass through.

[0015] Furthermore, a guide plate is fixedly provided on the side wall of the vertical plate. The guide plate is inclined and its bottom end extends above the discharge port.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: 1. This invention, through the cooperation of a drive component and a shaking component, utilizes a reciprocating rotation unit to drive the rope winding wheel to rotate intermittently, thereby intermittently pulling the pull rope, which in turn reciprocates and pulls the arc-shaped slide plate, causing the arc-shaped slide plate to vibrate, thus shaking off the gravel on the arc-shaped slide plate. The motor is controlled by an external controller, and the motor starts for a period of time and then stops until the value of the tension sensor returns to the initial value, indicating that the gravel on the arc-shaped slide plate has been cleared; the tension unit can pre-tighten the pull rope, keeping the pull rope in a taut state.

[0017] 2. This invention utilizes the coordination between the lifting assembly, horizontal plate, vertical rod, second pull rope, and cylinder. When the cylinder drives the horizontal plate to rise, it in turn drives the vertical rod to rise. At this time, the second pull rope is released, and under the action of gravity, the lifting plate and the load plate move downward, and the cone pierces through the clearance opening and inserts into the ground, increasing the stability of the support box. When the cylinder drives the horizontal plate to fall, it drives the vertical rod to fall. At this time, the second pull rope is pulled downward, and under the pull of the second pull rope, the lifting plate and the load plate move upward, allowing the crushed stone on the load plate to approach the discharge port, making it convenient for workers to remove the crushed stone from the collection bin.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] like Figures 1-15As shown, the present invention discloses a tunnel construction anti-collapse support device, comprising an arc-shaped support plate 11, with vertical plates 12 fixedly connected to both ends of the arc-shaped support plate 11, and arc-shaped protrusions 13 fixedly provided at both ends of the top surface of the arc-shaped support plate 11. The top surface of the arc-shaped support plate 11 forms flow channels 14 communicating to both sides through the two sets of arc-shaped protrusions 13. It also includes two sets of support boxes 4, with horizontal plates 5 fixedly provided at the bottom of the vertical plates 12. The horizontal plates 5 are respectively located at the top of the two sets of support boxes 4. The support box 4 has a material discharge port 6 located on one side of the horizontal plate 5. It also includes a cylinder 8, which is fixedly installed inside the support box 4. The output shaft of the cylinder 8 slides through the top of the support box 4 and is fixedly connected to the bottom of the horizontal plate 5. It also includes a shaking component 1, which is installed inside the flow channel 14. The support box 4 has a drive component 2, which is connected to the shaking component 1. It also includes a lifting component 3, which is installed inside the support box 4 and connected to the horizontal plate 5.

[0023] The drive component 2 drives the shaking component 1 to work, which can shake the gravel that falls into the flow channel 14 during tunnel construction and slide it into the support box 4, preventing the gravel from accumulating on the arc support plate 11 and causing safety hazards. At the same time, the cylinder 8 drives the horizontal plate 5 to move, which in turn drives the lifting component 3 to work. The lifting component 3 can pull the gravel collected in the support box 4 upward, making it convenient for workers to remove the gravel.

[0024] like Figures 1-15 As shown, the shaking component 1 includes an arc-shaped sliding plate 101 and a shock-absorbing spring 102. The shock-absorbing spring 102 is fixedly distributed at the bottom of the flow channel 14. The arc-shaped sliding plate 101 is fixedly connected to the top of the shock-absorbing spring 102, and the side wall of the arc-shaped sliding plate 101 slides in contact with the arc-shaped protrusions 13 on both sides. The arc-shaped sliding plate 101 covers the flow channel 14.

[0025] By cooperating with the curved sliding plate 101 and the shock-absorbing spring 102, when gravel falls onto the curved sliding plate 101, the shock-absorbing spring 102 can reduce the impact force of the gravel and improve the service life of the curved sliding plate 101. The curved sliding plate 101 is located inside the flow channel 14 and does not exceed the flow channel 14, allowing gravel to slide down along the top of the curved sliding plate 101. In addition, it should be noted that an elastic rubber strip (not shown in the figure) is provided on the side wall of the curved convex strip 13 away from the flow channel 14. The height of the elastic rubber strip exceeds the curved convex strip. When the arc-shaped protrusion 13 contacts the tunnel roof, the elastic rubber strip will also contact the top of the tunnel roof. The elastic rubber strip will be compressed to the side wall of the arc-shaped protrusion 13 away from the flow channel 14. When the arc-shaped protrusion 13 separates from the tunnel roof, the elastic rubber strip will rebound to its initial state. At this time, the elastic rubber strips on both sides can contain the arc-shaped protrusion 13 and the flow channel 14. When the arc-shaped protrusion 13 separates from the tunnel roof, the gravel generated will slide down along the arc-shaped protrusion 13, preventing the gravel from sliding down from one side of the arc-shaped protrusion 13.

[0026] like Figures 8-15 As shown, the drive assembly 2 includes a tension unit 21, a reciprocating rotation unit 22, and a pull rope 23. Two sets of vertical partitions 24 are fixedly installed inside the support box 4, dividing the support box 4 into a collection chamber, a cylinder chamber, and a drive chamber. The cylinder chamber is located between the collection chamber and the drive chamber, and the cylinder 8 is located inside the cylinder chamber. The material discharge port 6 is located above the collection chamber. The lifting assembly 3 is located inside the collection chamber, and the drive assembly 2 is located inside the drive chamber. The reciprocating rotation unit 22 is located on the bottom wall inside the drive chamber. A connecting plate 25 is fixed between the upper and lower inner walls of the drive chamber. The tension unit 21 is located on the connecting plate 25. One end of the pull rope 23 is connected to the reciprocating rotation unit 22, and the other end passes around the tension unit 21 and slides out from the top of the drive chamber to connect with the arc-shaped slide plate 101.

[0027] By cooperating with the drive component 2 and the shaking component 1, the reciprocating rotation unit 22 pulls the pull rope 23 back and forth, thereby pulling the arc-shaped slide plate 101 back and forth, causing the arc-shaped slide plate 101 to vibrate, thus shaking off the gravel on the arc-shaped slide plate 101; the tension unit 21 can pre-tighten the pull rope 23, so that the pull rope 23 is in a taut state.

[0028] like Figures 8-15As shown, the reciprocating rotation unit 22 includes a motor 221, an incomplete gear 222, a driven gear 223, and a rope reel 224. The motor 221 is fixedly mounted on the bottom wall of the inner wall of the drive chamber. The incomplete gear 222 is fixedly mounted on the output shaft of the motor 221. A central shaft is horizontally connected to the center of the driven gear 223. One end of the central shaft is rotatably mounted on the inner wall of one side of the drive chamber through a bearing, and the other end of the central shaft is rotatably mounted on a vertical partition 24 near the drive chamber through a bearing. The driven gear 223 intermittently meshes with the incomplete gear 222. The rope reel 224 is fixedly mounted on the central shaft, and one end of the pull rope 23 is fixedly connected to the rope reel 224.

[0029] like Figures 8-15 As shown, the tension unit 21 includes a mounting plate 211, a tension wheel 212, a telescopic rod 213, a tension spring 214, and a force sensor 215. The telescopic rods 213 are symmetrically fixed on the connecting plate 25. The mounting plate 211 is fixed at the end of the telescopic rods 213 away from the connecting plate 25. The force sensor 215 is fixed on the connecting plate 25 and located between the two sets of telescopic rods 213. One end of the tension spring 214 is fixedly connected to one end of the force sensor 215, and the other end of the tension spring 214 is fixedly connected to the mounting plate 211. The tension wheel 212... The tension unit 21 is rotatably mounted on the mounting plate 211. It also includes a guide rope wheel 216. A central shaft 216 is horizontally connected to the center of the guide rope wheel 216. One end of the central shaft 216 is rotatably mounted on the inner wall of the drive chamber via a bearing. The other end of the central shaft 21 is rotatably mounted on a vertical partition 24 near the drive chamber via a bearing. The guide rope wheel 216 is located directly above the winding rope wheel 224 and diagonally above the tension wheel 212. The other end of the pull rope 23 passes through the tension wheel 212 and the guide rope wheel 216 in sequence and slides out from the top of the drive chamber and is fixed to the inner wall of the arc-shaped slide plate 101.

[0030] The reciprocating rotation unit 22 can drive the rope winding wheel 224 to rotate intermittently, thereby causing the pull rope 23 to be pulled intermittently. The motor 221 is controlled by an external controller. The motor 221 will stop after a period of time each time it starts, until the value of the tension sensor 215 returns to the initial value. At this time, it indicates that the gravel on the arc-shaped slide plate 101 has been cleared.

[0031] like Figures 1-3 , Figure 13 As shown, a horizontal support 9 is fixed between the two sets of vertical plates 12. Fixed pulleys 217 are installed on both sides of the top of the horizontal support 9. The pull rope 23 slides out from the top of the drive compartment, slides through the horizontal support 9 and the arc-shaped support plate 11, and passes around the fixed pulleys 217. A reinforcing plate 10 is fixed between the horizontal support 9 and the arc-shaped support plate 11.

[0032] By setting up horizontal supports 9 and reinforcing plates 10, the support strength of vertical plates 12 and curved support plates 11 can be increased, reducing the risk of deformation of vertical plates 12 and curved support plates 11 under stress.

[0033] like Figure 6 , Figure 7 , Figure 8 , Figure 15 As shown, the lifting assembly 3 includes a lifting plate 31, a load plate 32, and a second shock-absorbing spring 33. The lifting plate 31 is slidably disposed in the collection chamber. The second shock-absorbing spring 33 is fixedly distributed on the top of the lifting plate 31. The load plate 32 is fixedly disposed on the top of the second shock-absorbing spring 33 and is slidably disposed in the collection chamber. Limiting strips 34 are fixedly disposed on the inner walls of the left and right sides of the inner wall of the collection chamber. The lifting plate 31 and the load plate 32 are slidably engaged with the limiting strips 34. A vertical rod 35 is fixedly disposed at the bottom of the horizontal plate 5 and slides through the top of the cylinder chamber. A second pull rope 36 is fixedly connected to the bottom end of the vertical rod 35. The other end of the second pull rope 36 slides through the top of the cylinder chamber and extends into the collection chamber, and slides through the load plate 32 and is fixedly connected to the lifting plate 31.

[0034] like Figure 2 , Figure 8 , Figure 11 , Figure 15 As shown, the bottom of the lifting plate 31 is also fixedly provided with a cone spike 38, and the bottom of the collection chamber is provided with an avoidance opening 39 for the cone spike 38 to pass through.

[0035] Through the coordination of the lifting assembly 3, horizontal plate 5, vertical rod 35, pull rope 36, and cylinder 8, when cylinder 8 drives horizontal plate 5 to rise, it in turn drives vertical rod 35 to rise. At this time, pull rope 36 is released. Under the action of gravity, lifting plate 31 and load plate 32 move downward, and cone 38 passes through clearance opening 39 and inserts into the ground, increasing the stability of support box 4. When cylinder 8 drives horizontal plate 5 to fall, it drives vertical rod 35 to fall. At this time, pull rope 36 is pulled downward. Under the pull of pull rope 36, lifting plate 31 and load plate 32 move upward, so that the gravel on load plate 32 can approach the discharge port 6, making it convenient for workers to remove gravel from the collection bin.

[0036] like Figures 6-15 As shown, a fixed pulley 37 is installed on the top of the support box 4. The fixed pulley 37 is located on one side of the material discharge port 6. The pull rope 36 slides through the top of the cylinder chamber and then passes around the fixed pulley 37. The fixed pulley 37 facilitates the pull rope 36 to enter the collection chamber and reduces the friction between the pull rope 36 and the top of the support box 4.

[0037] like Figures 1-5As shown, a guide plate 7 is fixed on the side wall of the vertical plate 12. The guide plate 7 is inclined and its bottom end extends above the discharge port 6. The guide plate 7 guides the crushed stone into the collection bin. In order to reduce noise, a sponge pad (not shown in the figure) is laid on the top of the guide plate 7 to buffer and dampen the falling crushed stone.

[0038] In practical use, by starting the cylinder 8, the horizontal plate 5, vertical plate 12, arc-shaped support plate 11 and arc-shaped protrusion 13 are driven to rise. The arc-shaped protrusion 13 abuts against the top of the tunnel, the arc-shaped support plate 11 provides overall support for the top, and the arc-shaped protrusion 13 provides local support for the top of the tunnel. The horizontal bracket 9 and the reinforcing plate 10 increase the support strength of the arc-shaped support plate 11. The flow channel 14 collects the gravel generated during construction and slides it down from both sides to avoid injuring workers, eliminate safety hazards, and ensure construction safety. When cylinder 8 drives horizontal plate 5 to rise, it in turn drives vertical rod 35 to rise. At this time, pull rope 36 is released. Under the action of gravity, lifting plate 31 and load plate 32 move downward, and cone 38 passes through clearance opening 39 and inserts into the ground to increase the stability of support box 4. When the debris generated at the top of the tunnel gets stuck between the flow channel 14 and the tunnel top, the weight of the debris will cause the curved slide plate 101 to move downwards, compressing the shock-absorbing spring 102. As the curved slide plate 101 moves downwards, the pull rope 23 will move downwards under the tension of the tension spring 214 on the tension unit 21. At this time, the tension spring 214 will contract (the initial state of the tension spring 214 is the stretched state). At this time, the tension value of the tension sensor 215 will change, and the tension sensor 215 will transmit the changed electrical signal to the external controller. The external controller controls the motor 221 to start. The motor 221 drives the incomplete gear 222 to rotate, which in turn drives the driven gear 223 to rotate, which in turn drives the rope winding wheel 224 to rotate and wind up the pull rope 23. At this time, the pull rope 23 is pulled, which in turn causes the curved slide plate 101 to move downwards, and the shock-absorbing spring 102... 02 is continuously compressed, and the tension spring 214 is stretched. At this time, the space between the arc-shaped slide plate 101 and the top of the tunnel increases. The crushed stone will slide down due to the increased space. When the incomplete gear 222 separates from the driven gear 223, under the rebound action of the shock-absorbing spring 102 and the tension spring 214, the arc-shaped slide plate 101 quickly rebounds upward, and the arc-shaped slide plate 101 vibrates, causing the crushed stone on the arc-shaped slide plate 101 to be shaken off. The motor 221 will stop after starting for a period of time each time until the value of the tension sensor 215 returns to the initial value. At this time, it indicates that the crushed stone on the arc-shaped slide plate 101 has been cleaned up. The crushed stone sliding down from the chute 14 will enter the collection bin through the guide plate 7 and fall onto the load plate 32. The shock-absorbing spring 33 reduces the impact force of the crushed stone on the load plate 32 and improves the service life of the load plate 32. When cylinder 8 drives horizontal plate 5 to descend, it drives vertical rod 35 to descend. At this time, pull rope 36 is pulled downward. Under the pull of pull rope 36, lifting plate 31 and load plate 32 move upward, so that the crushed stone on load plate 32 can approach the discharge port 6, making it convenient for workers to remove the crushed stone from the collection bin.
