Description

Technical Field

[0001] This utility model relates to the field of tunnel construction, specifically a lining trolley for the construction of sidewalls in open-cut tunnels. Background Technology

[0002] Tunnel construction refers to the process of excavating tunnels suitable for transportation, engineering, or other purposes in underground, mountain, or underwater environments using various methods and equipment. Lining trolleys are a type of mechanical equipment specifically used for lining operations in tunnel construction.

[0003] In existing technologies, when using a lining trolley to pour concrete, a hand-held vibrator is typically inserted into the concrete to vibrate it. However, manual operation can cause arm discomfort and physical fatigue after a period of vibration, making it impossible to work for extended periods. This not only affects construction efficiency but also increases the workload of workers. Furthermore, when gaps appear in the filled cement, it is difficult to fill them, further impacting the construction progress.

[0004] Therefore, a lining trolley for the construction of the sidewall of a tunnel is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technology, when using a lining trolley to pour concrete, it is generally done manually by inserting a hand-held vibrator into the concrete to vibrate it. However, manual operation can cause arm discomfort and fatigue after a period of vibration, making it impossible to work for long periods of time. This not only affects construction efficiency but also increases the workload of workers. Furthermore, when gaps appear in the filled cement, it is difficult to fill them, further affecting the construction progress. This utility model proposes a lining trolley for the construction of open-cut sidewalls.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The lining trolley for the construction of the side wall of a tunnel according to this utility model includes a trolley body. Multiple lining plates are fixedly connected to the outside of the trolley body by support rods. Multiple sets of movable seats are slidably connected to the outside of the trolley body. Filling pipes are equidistantly slidably connected to both sides of the inside of the multiple lining plates. Filling holes are opened on both sides of the inside of the filling pipes. A vibration assembly is provided inside the movable seat. A transmission assembly is provided outside the trolley body. The vibration assembly includes a fixed column. Fixed columns are fixedly connected to the inside of the multiple movable seats. Vibration rods are slidably connected to the outside of the multiple fixed columns.

[0007] Preferably, the transmission assembly includes a first reciprocating screw and a second reciprocating screw. The first reciprocating screw is rotatably connected to the top of the vehicle body, and the second reciprocating screw is rotatably connected to the outer sides of the vehicle body. A first motor is fixedly connected to the outer side of the vehicle body via a mounting plate. The output end of the first motor is fixedly connected to the first reciprocating screw. The movable seat on the top of the vehicle body is connected to the outside of the first reciprocating screw via a screw-nut pair.

[0008] Preferably, the transmission assembly further includes a first synchronous pulley, a first synchronous pulley is fixedly connected to the outer side of the first reciprocating screw, and a second synchronous pulley is fixedly connected to the outer end of each of the two second reciprocating screws, and the first synchronous pulley and the two second synchronous pulleys are respectively connected by two synchronous belts.

[0009] Preferably, the vibrating assembly further includes a second motor, which is fixedly connected to the inside of the fixed column via a mounting block. A cam is fixedly connected to the output end of the second motor, and a connecting rod is rotatably connected to the outer side of the cam. A sliding rod is slidably connected to the bottom of the vibrating rod, and the bottom of the sliding rod is hinged to the top of the connecting rod via a pin.

[0010] Preferably, a first spring is provided between each of the plurality of packing tubes and the liner plate, and corrugated telescopic tubes are installed on both sides of the outer side of the vehicle body.

[0012] Preferably, a sliding plate is slidably connected inside the vibrating rod, and a second spring is provided inside the vibrating rod and on both sides of the sliding plate. One end of the sliding rod is fixedly connected to the sliding plate.

[0013] The advantages of this utility model are:

[0014] 1. This utility model uses the reciprocating motion of multiple moving seats to drive a high-frequency vibrating rod to perform high-frequency hammering on the lining plate. The reciprocating motion of the moving seats improves the uniformity of vibration, removes air bubbles from the concrete on the top side of the lining plate, and thus makes the concrete densely bonded, thereby ensuring the strength of the building. It avoids the problem of fatigue caused by manually holding the vibrator, which makes it impossible to work for a long time and affects the construction efficiency. Furthermore, the cooperation between the discharge pipe and the filling pipe can fill any gaps in the concrete, avoiding the problem that the gaps in the concrete affect the construction quality and thus prevent safety hazards in subsequent use. This effectively improves the practicality and functionality of this device.

[0015] 2. This utility model utilizes the elastic properties of the second springs set on both sides of the slide plate to store energy during the hammering process. When the spring is compressed, it stores energy, and when it is released, the spring quickly returns to its shape, converting the stored energy into kinetic energy and generating impact force, thereby improving the vibration effect on concrete.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, a lining trolley for constructing the sidewall of a tunnel includes a trolley body 1. Multiple lining plates 2 are fixedly connected to the outside of the trolley body 1 via support rods. Multiple sets of movable seats 3 are slidably connected to the outside of the trolley body 1. Filling pipes 6 are equidistantly slidably connected to both sides of the interior of each of the multiple lining plates 2. Filling holes 7 are opened on both sides of the interior of each filling pipe 6. A vibration assembly is installed inside the movable seats 3. A transmission assembly is installed outside the trolley body 1. The vibration assembly includes fixed columns 4. Fixed columns 4 are fixedly connected to the interior of each of the multiple movable seats 3. Vibrating rods 5 are slidably connected to the exterior of each of the multiple fixed columns 4. The transmission assembly includes a first reciprocating screw 8 and a second reciprocating screw 9. The first reciprocating screw 8 is rotatably connected to the top of the trolley body 1, and the second reciprocating screw 9 is rotatably connected to both sides of the outside of the trolley body 1. A first motor 10 is fixedly connected to one side of the outside of the trolley body 1 via a mounting plate. The output end of a motor 10 is fixedly connected to a first reciprocating screw 8. The movable seat 3 on the top of the vehicle body 1 is connected to the outside of the first reciprocating screw 8 through a screw and nut pair. The transmission assembly also includes a first synchronous pulley 11. The first synchronous pulley 11 is fixedly connected to the outer side of the first reciprocating screw 8. The outer ends of the two second reciprocating screws 9 are each fixedly connected to a second synchronous pulley 12. The first synchronous pulley 11 and the two second synchronous pulleys 12 are respectively connected by two synchronous belts 13. The vibration assembly also includes a second motor 14. The second motor 14 is fixedly connected to the inside of the fixed column 4 through a mounting block. The output end of the second motor 14 is fixedly connected to a cam 15. The outer side of the cam 15 is rotatably connected to a connecting rod 16. The bottom of the vibrating rod 5 is slidably connected to a slide rod 17. The bottom of the slide rod 17 and the top of the connecting rod 16 are hinged by a pin.

[0026] During operation, multiple lining plates 2 are spliced ​​together to form an arc-shaped structure. After concrete is poured onto the top side of the lining plate 2, the first motor 10 is started, driving the first reciprocating screw 8 and the first synchronous pulley 11 to rotate. This causes the first reciprocating screw 8 to drive the corresponding moving seat 3 to reciprocate through the screw-nut pair. At the same time, the first synchronous pulley 11 drives the corresponding second synchronous pulley 12 and the second reciprocating screw 9 to rotate through two synchronous belts 13. This causes the two second reciprocating screws 9 to drive the corresponding moving seat 3 to reciprocate through the screw-nut pair, thus achieving synchronous reciprocating motion of multiple moving seats 3. While the moving seats 3 are moving, the second motor 14 is started, driving the cam 15 to rotate. The cam 15 then drives the connecting rod 16 to push the slide rod 17 to reciprocate. This causes the slide rod 17, in conjunction with the second spring 23, to drive the slide plate 22 and the vibrator 5 to reciprocate, allowing the vibrator 5 to perform high-frequency hammering on the lining plate 2. Combined with the reciprocating motion of the moving seats 3, this achieves uniform reciprocating motion of the lining plate 2. Hammering removes air bubbles from the concrete on the top side of the liner plate 2, thus ensuring a dense and solid concrete structure and guaranteeing the building's strength. This avoids the fatigue and inefficiency associated with manual vibrating, which can occur with holding a vibrator. When voids exist in the concrete, the filler tube 6 can be stretched through the corrugated expansion tube 19 and inserted into the corresponding filler tube 6. The filler tube 6 is then pushed outwards towards the liner plate 2, compressing the first spring 18 to deform it until the filler hole 7 in the filler tube 6 moves to the outside of the liner plate 2, aligning the discharge hole 21 in the discharge pipe 20 with the filler hole 7 in the filler tube 6. Concrete is then discharged to fill the voids. After filling, the discharge pipe 20 is removed, and the filler tube 6 returns to its original position under the rebound force of the first spring 18. This prevents voids in the concrete from affecting construction quality and causing safety hazards in subsequent use, effectively improving the practicality and functionality of the device.

[0027] Among them, a first spring 18 is provided between multiple packing tubes 6 and liner 2, corrugated telescopic tubes 19 are installed on both sides of the exterior of the vehicle body 1, and discharge pipes 20 that cooperate with the packing tubes 6 are fixedly connected to the exterior of the two corrugated telescopic tubes 19. Discharge holes 21 that cooperate with the packing holes 7 are opened on both sides of the interior of the discharge pipes 20. Wheels are symmetrically installed on both sides of the bottom of the vehicle body 1. The first motor 10 and the second motor 14 are electrically connected to the external controller.

[0028] Through the above technical solution, the device can be pushed and moved by the wheels, and the corrugated telescopic tube 19 can be used to stretch the discharge pipe 20, thereby facilitating the replenishment of concrete. The external controller allows the staff to quickly control the first motor 10 and the second motor 14.

[0029] Example 2

[0030] Please see Figure 3 As shown in the first embodiment, as another implementation of the present invention, the vibrating rod 5 is slidably connected to the slide plate 22, and the vibrating rod 5 is provided with a second spring 23 on both sides of the slide plate 22. One end of the slide rod 17 is fixedly connected to the slide plate 22.

[0031] During operation, the second springs 23 set on both sides of the slide plate 22 store energy during the hammering process through their elastic properties. When the spring is compressed, it stores energy. When it is released, the spring quickly returns to its shape, converting the stored energy into kinetic energy and generating impact force, thereby improving the vibration effect on concrete.

[0032] Working principle: Multiple lining plates 2 are spliced ​​together to form an arc-shaped structure. After concrete is poured onto the top side of the lining plate 2, the first motor 10 is started, driving the first reciprocating screw 8 and the first synchronous pulley 11 to rotate. This causes the first reciprocating screw 8 to drive the corresponding moving seat 3 to reciprocate through the screw-nut pair. At the same time, the first synchronous pulley 11 drives the corresponding second synchronous pulley 12 and the second reciprocating screw 9 to rotate through two synchronous belts 13. This causes the two second reciprocating screws 9 to drive the corresponding moving seat 3 to reciprocate through the screw-nut pair, thus achieving synchronous reciprocating motion of multiple moving seats 3. The second motor 10 is started simultaneously with the movement of the moving seats 3. Motor 14 drives cam 15 to rotate, cam 15 then drives connecting rod 16 to push slide rod 17 to reciprocate. Slide rod 17, in conjunction with second spring 23, drives slide plate 22 and vibrator 5 to reciprocate, causing vibrator 5 to perform high-frequency hammering on lining plate 2. Combined with the reciprocating motion of moving seat 3, this achieves uniform hammering of lining plate 2, removing air bubbles from the concrete on the top side of lining plate 2, thus ensuring dense bonding and guaranteeing the building's strength. This avoids the fatigue and inefficiency associated with manually holding a vibrator, which can lead to prolonged work and reduced construction efficiency. When voids exist in the concrete... The packing tube 6 can be stretched through the corrugated expansion tube 19 and then inserted into the corresponding packing tube 6. The packing tube 6 is then pushed outwards towards the liner plate 2, compressing the first spring 18 to deform it until the packing hole 7 in the packing tube 6 moves to the outside of the liner plate 2, and the discharge hole 21 in the discharge pipe 20 aligns with the packing hole 7 in the packing tube 6. Concrete is then discharged to fill the gaps. After filling, the discharge pipe 20 is removed, and the packing tube 6 returns to its original position under the rebound force of the first spring 18. This prevents gaps in the concrete from affecting construction quality and thus avoiding safety hazards during subsequent use. This effectively improves the practicality and functionality of the device. The device can be moved by the wheels, and the corrugated telescopic tube 19 can be used to stretch the discharge pipe 20, thus facilitating the replenishment of concrete. The external controller allows the operator to quickly control the first motor 10 and the second motor 14. The elasticity of the second springs 23 on both sides of the slide plate 22 stores energy during the hammering process. When the spring is compressed, it stores energy, and when it is released, the spring quickly returns to its shape, converting the stored energy into kinetic energy and generating impact force, thereby improving the vibration effect on the concrete.
