Description

Technical Field

[0001] The present invention relates to the technical field of lining trolleys, and particularly relates to a lining trolley and its formwork support device. Background Art

[0002] A lining trolley is a special equipment used for concrete lining pouring in tunnel construction, which has the characteristics of high efficiency, precision and safety, and is widely used in tunnel projects such as railways, highways and subways.

[0003] A tunnel lining trolley disclosed in a Chinese patent with the publication number CN117780391B realizes the relaxation of the sleeve rope by making the moving distance of the ring frame greater than the moving distance of the second pipe section when the second pipe section is docked with the grouting pipe, so that the flexible pipe can be opened. When the second pipe section and the grouting pipe need to be separated, the telescopic component first tightens the sleeve rope to tighten the flexible pipe, avoiding a large amount of concrete from coming out of the flexible pipe, thereby reducing the scattering amount of concrete, reducing the waste of resources and the burden of cleaning.

[0004] However, the above-mentioned prior art has the following defects: when replacing the docked grouting pipe, docking actions still need to be carried out, that is, separating from the original grouting pipe and then docking with the next grouting pipe, which reduces the switching efficiency of the grouting pipe. And when separating from the grouting pipe in the above technical solution, only most of the concrete can be prevented from coming out, and there will still be a small amount of concrete coming out, so subsequent cleaning operations are still required, and part of the concrete will remain in the grouting pipe and cannot be discharged, requiring subsequent cleaning. In addition, when pouring in the above prior art, the concrete cannot be vibrated, and there is no operating space between the tunnel and the side formwork, making it inconvenient to use vibration equipment and reducing the concrete vibration efficiency. And when the formwork support device of the above prior art supports the movement of the entire lining trolley, it is not convenient to turn at the turning of the tunnel, resulting in the movement of the entire lining trolley being not flexible enough.

Detailed implementation mode

[0018] Example 1, as Figures 1-3 and Figures 6-8 shown, a lining trolley proposed by the present invention includes a top formwork 1, side formworks 2 and a vehicle body 3; there are two side formworks 2 which are respectively rotatably arranged on both sides of the top formwork 1 and are connected to the vehicle body 3 through a telescopic member b 4. The telescopic member c 6 includes, but is not limited to, devices such as cylinders that can drive the side formwork 2 to expand or retract. The telescopic device b is used to drive the side formwork 2 to expand and retract, which is the prior art here; the vehicle body 3 is connected to the top formwork 1; chutes 201 are provided at the grouting ports on the side formworks 2 and the top formwork 1, and a pouring mechanism and a collection mechanism are further included; The pouring mechanism includes a box body 14, a sealing block 15, a telescopic member a 16, a vibrating assembly, a driving assembly and a grouting pipe 13; the box body 14 is connected to the chute 201 on the side formwork 2; there are two sealing blocks 15 which are slidably arranged in the chute 201; the driving assembly is arranged on the box body 14 and is used to drive the sealing block 15 to slide, so as to realize the closing and separation between the two sealing blocks 15, and further realize the opening and closing functions of the grouting port; a pipe a 29 is slidably arranged on the grouting pipe 13; the pipe a 29 passes through the box body 14 and is hermetically arranged on the contact surface with the box body 14 to ensure that the box body 14 is in a sealed state during the sliding process of the pipe a 29, and a vibrating assembly is arranged on the pipe a 29; In this embodiment, the driving assembly drives the two sealing blocks 15 to move away from each other to open the grouting port, and at the same time drives the pipe a 29 to move and makes the pipe a 29 pass through the grouting port to realize the concrete pouring function. After the pouring is completed, the driving assembly drives the pipe a 29 to reset and at the same time drives the two sealing blocks 15 to move towards each other to realize the automatic closing function of the grouting port, without the need for staff to manually open or close the grouting port, improving the concrete pouring efficiency.

[0019] The collecting mechanism includes an air pump, a docking pipe 28, a plate a 34 and a collecting box 32; the air pump is arranged on the box body 14 and communicated with the box body 14; the other end of the grouting pipe 13 is connected to the docking pipe 28; an opening is formed on the collecting box 32; a filter cloth 33 is arranged on the opening, and the opening is arranged so that the gas entering the collecting box 32 can be discharged, and the filter cloth 33 can prevent the concrete in the collecting box 32 from falling off through the opening; one end of the collecting box 32 is connected to the plate a 34; two sliders a 30 are connected to the plate a 34, and a docking nozzle 5 is arranged on the plate a 34; a slider b 31 is connected to the collecting box 32; a grouting space is formed between the two sliders a 30 and the plate a 34; a collecting space is formed among the collecting box 32, the slider b 31 and the slider a 30; the slider a 30 and the slider b 31 are slidably arranged inside the docking pipe 28.

[0020] It should be noted that a movable delivery pump is provided on the lining trolley, and the grout outlet pipe on the delivery pump is docked with the docking nozzle 5, which is the prior art here.

[0021] In this embodiment, when the delivery pump is docked with the docking nozzle 5, the delivery pump drives the plate a 34 to move, thereby driving the collecting box 32 to move, so that the slider a 30 and the slider b 31 slide inside the docking pipe 28. When the grouting space between the slider a 30 moves to the grouting pipe 13, the concrete can be conveyed into the grouting pipe 13. When switching the grouting pipe 13, only need to make the delivery pump continue to move to the next grouting pipe 13, and the grouting space will move to the next grouting pipe 13 accordingly, without the need for the delivery pump to separate from the grouting pipe 13 and then dock with the next grouting pipe 13, significantly improving the concrete pouring efficiency.

[0022] When switching the grouting pipe 13, the residual concrete in the grouting space moves to the next grouting pipe 13 along with the grouting space; the collecting space will then move to the previous grouting pipe 13, and the concrete ejected from the previous grouting pipe 13 will fall into the collecting space for automatic recovery. At the same time, the air pump is used to pump air into the box body 14. Since the box body 14 is in a sealed state, the gas in the box body 14 will enter the pipe a 29 and squeeze the concrete in the pipe a 29 and will also squeeze the concrete in the grouting pipe 13, squeezing out the concrete in the grouting pipe 13. The squeezed concrete will fall into the collecting space for recovery, realizing the automatic cleaning function of the grouting pipe 13, without the need for subsequent cleaning by staff, reducing the workload of the staff. When the collecting space moves to the next grouting pipe 13, the concrete collected in the collecting space will move to the next grouting pipe 13 accordingly.

[0023] Embodiment 2, as Figures 4-6As shown in the figure, a lining trolley proposed by the present invention, compared with the first embodiment, this embodiment also details the structure of the driving component. The driving component includes a telescopic component a16, a gear a19, a gear b21, a toothed plate 18, and a plate b27. The plate b27 is connected to the pipe a29. The telescopic component a16 includes, but is not limited to, devices such as cylinders that can drive the movement of the plate b27. The telescopic component a16 is provided on the box body 14 and is connected to the plate b27; the gear a19 and the gear b21 are in transmission connection; the toothed plate 18 is connected to the plate b27 and meshes with the gear a19; a toothed row is provided on the sealing block 15 and meshes with the gear b21; there are two gears a19 and gear b21 each, which are rotatably connected to the box body 14, and a synchronous pulley is connected between the gear a19 and the gear b21; a synchronous belt is provided between the synchronous pulleys.

[0024] In this embodiment, the telescopic component a16 drives the plate b27 to move closer to the box body 14. The plate b27 drives the pipe a29 to move towards the grouting port, and at the same time drives the toothed plate 18 to move. The toothed plate 18 drives the gear a19 to rotate counterclockwise (refer to Figure 4 ), the gear a19 drives the gear b21 to rotate counterclockwise through the synchronous belt, and the gear b21 drives the sealing block 15 to move. When the pipe a29 moves to the grouting port, the two sealing blocks 15 have moved away from each other, so that the grouting port is opened, facilitating the pipe a29 to pass through the grouting port for pouring operations; after the grouting operation is completed, the telescopic component a16 drives the pipe a29 to move away from the grouting port and reset. At the same time, the sealing blocks 15 approach each other under the action of the driving component and close the grouting port, realizing the automatic opening and closing functions of the grouting port, without the need for staff to manually open or close the grouting port, improving the pouring efficiency of concrete.

[0025] Embodiment Three, as Figures 4-6 shown in the figure, a lining trolley proposed by the present invention, compared with the second embodiment, this embodiment also details the structure of the vibrating component. The vibrating component includes a motor a17, a gear column 22, a gear c24, a turntable 23, and a vibrating rod 26; the pipe a29 is in limit sliding connection with the turntable 23; the outer peripheral surface of the turntable 23 is rotatably connected to the gear c24; there are multiple vibrating rods 26, which are connected to the gear c24; a sealing plate 25 is provided on the pipe a29, a ring is rotatably provided on the sealing plate 25, and the vibrating rod 26 is connected to the ring and penetrates through the ring; the motor a17 is installed on the box body 14 and its output end is connected to the gear column 22; the gear column 22 meshes with the gear c24.

[0026] It should be noted that multiple groups of grouting ports are provided on the side formwork 2 from bottom to top. Each grouting port is provided with a pouring mechanism, and each group of grouting ports corresponds to a collection mechanism; in this patent Figure 1 and Figure 2 only one group of grouting ports is shown as an example to illustrate the technical solution of this patent.

[0027] In this embodiment, multiple groups of grouting ports in the side formwork 2 are sorted from bottom to top as the first group, the second group, and the third group. When the grouting operation of the grouting pipe 13 on the first group of grouting ports is completed, the grouting ports are closed through the sealing block 15. When the grouting pipe 13 on the second group of grouting ports is performing the grouting operation, the vibrating assembly on the first group of grouting ports prepares for work. First, the driving assembly is used to open the first group of grouting ports, and at the same time, the pipe a 29 drives the gear c 24, the vibrating rod 26, and the sealing plate 25 to move close to the first group of grouting ports. The vibrating rod 26 passes through the first group of grouting ports and extends into the concrete. The sealing plate 25 moves to the first group of grouting ports to seal the first group of grouting ports, preventing the concrete from leaking into the inner side of the box body 14 during the vibration process. Then, the motor a 17 drives the gear column 22 to rotate, the gear column 22 drives the gear c 24 to rotate, and the gear c 24 drives the vibrating rod to rotate to stir the concrete, realizing the vibrating function of the concrete. And so on, when the grouting pipe 13 on the third group of grouting ports is performing the grouting operation, the vibrating assembly on the second group of grouting ports prepares for work.

[0028] Embodiment 4, please refer to Figures 1-2 and Figure 9 , the present invention also proposes a formwork support device applied to the lining trolley described in any one of the above-mentioned Embodiment 1 to Embodiment 3, including a guiding mechanism and a moving mechanism; There are two guiding mechanisms, which are respectively arranged at both ends of the vehicle body 3; the guiding mechanism includes a telescopic component c 6 and a guide wheel 7; there are two telescopic components c 6, which are connected to the vehicle body 3. The telescopic component c 6 includes, but is not limited to, devices such as cylinders that can drive the guide wheel 7 to move. One end of the telescopic component c 6 is connected to the guide wheel 7; The moving mechanism includes a moving wheel a 10, a moving wheel b 20, a motor b 9, and a carrier block 12; the carrier block 12 is connected to the vehicle body 3; the moving wheel a 10 is connected to the carrier block 12; the moving wheel b 20 is rotatably arranged on the carrier block 12; the motor b 9 is arranged on the carrier block 12 and is in transmission connection with the moving wheel a 10. A support member 11 is slidably arranged on the vehicle body 3, and a telescopic component e 8 is arranged on the vehicle body 3, and the telescopic component e 8 is connected to the support member 11.

[0029] It should be noted that the transmission connection method between the motor b 9 and the moving wheel a 10 includes, but is not limited to: the output end of the motor b 9 is connected with a gearbox, and the gearbox and the moving wheel a 10 are connected through a gear-synchronous belt system (the gear-synchronous belt system is a prior art, and the specific structure will not be described in detail here).

[0030] In this embodiment, the telescopic member c6 drives the guide wheel 7 to move, so that the guide wheel 7 contacts the inner wall of the tunnel. When the motor b9 drives the moving wheel a10 to move, it cooperates with the moving wheel b20 to drive the vehicle body 3 to move, and then drives the entire lining trolley to move. When moving to the tunnel bend, under the guiding action of the guide wheel 7, the entire lining trolley turns, facilitating the flexible movement of the lining trolley at the tunnel bend. When pouring operations are carried out, the telescopic member e8 drives the support member 11 to move downward. When the support member 11 contacts the ground, the support member 11 cannot continue to move downward. At this time, the telescopic member e8 will jack up the vehicle body 3, and the vehicle body 3 drives the top formwork 1 to move upward. At this time, the moving wheel a10 and the moving wheel b20 are away from the ground, and the support member 11 plays a supporting role for the vehicle body 3, ensuring the stability of the entire lining trolley during pouring operations.

[0031] It should be noted that the specific operation of the lining trolley is intelligently controlled by an external control program.

[0032] In summary, the present invention first drives the guide wheel 7 to move through the telescopic member e8, so that the guide wheel 7 contacts the inner wall of the tunnel, playing a guiding role in the movement of the entire lining trolley. Then, the motor b9 is used to drive the moving wheel a10 to move, and it cooperates with the moving wheel b20 to drive the vehicle body 3 to move, realizing the moving function of the entire lining trolley.

[0033] When the lining trolley moves to the pouring location, the telescopic member e8 drives the support member 11 to move downward. When the support member 11 contacts the ground, the support member 11 cannot continue to move downward. At this time, the telescopic member e8 will jack up the vehicle body 3, and the vehicle body 3 drives the top formwork 1 to move upward. At this time, the moving wheel a10 and the moving wheel b20 are away from the ground, and the support member 11 plays a supporting role for the vehicle body 3, ensuring the stability of the entire lining trolley during pouring operations. Then, the telescopic member b4 is used to drive the side formwork 2 to unfold, completing the preparatory work before pouring (this is the prior art of the existing lining trolley and will not be elaborated in detail here).

[0034] During pouring operations, first, the conveying pump is docked with the outermost docking nozzle 5 on the collecting mechanism corresponding to the first group of grouting ports. After docking, the telescopic member a16 drives the plate b27 to move closer to the box body 14. The plate b27 drives the pipe a29 to move towards the grouting port, and at the same time drives the toothed plate 18 to move. The toothed plate 18 drives the gear a19 to rotate counterclockwise (refer to Figure 4), the gear a19 drives the gear b21 to rotate counterclockwise through the synchronous belt. The gear b21 drives the sealing block 15 to move. When the pipe a29 moves to the grouting port, the two sealing blocks 15 have moved away from each other, opening the grouting port and facilitating the pouring operation of the pipe a29 through the grouting port. After the grouting operation is completed, the telescopic component a16 drives the pipe a29 away from the grouting port and resets it. At the same time, the sealing blocks 15 approach each other under the action of the driving component and close the grouting port, realizing the automatic opening and closing functions of the grouting port, eliminating the need for staff to manually open or close the grouting port and improving the concrete pouring efficiency.

[0035] After the outermost grouting pipe 13 completes the pouring operation, the delivery pump drives the plate a34 to move to the next grouting pipe 13 (i.e., the grouting space moves to the next grouting pipe 13), and then drives the collection box 32 to move to the previous grouting pipe 13 (i.e., the collection space moves to the next grouting pipe 13), thus realizing the switching function of the grouting pipe 13. There is no need for the delivery pump to separate from the grouting pipe 13 and then dock with the next grouting pipe 13, significantly improving the concrete pouring efficiency. The concrete discharged from the previous grouting pipe 13 will fall into the collection space for automatic recycling. At the same time, the air pump is used to pump air into the box body 14. Since the box body 14 is in a sealed state, the gas in the box body 14 will enter the pipe a29 and squeeze the concrete in the pipe a29 and will also squeeze the concrete in the grouting pipe 13, extruding the concrete in the grouting pipe 13 from the other end of the grouting pipe 13. The extruded concrete will fall into the collection space for recycling, realizing the automatic cleaning function of the grouting pipe 13 without subsequent cleaning by staff, reducing the workload of the staff. When the collection space moves to the next grouting pipe 13, the concrete collected in the collection space will move to the next grouting pipe 13 accordingly. And so on. After completing the pouring operation of all the grouting pipes 13 at the first group of grouting ports, the cleaning of the grouting pipe 13 and the recycling of the concrete can be realized. Then, the staff needs to place the container for recycling the concrete at one end of the docking pipe 28, and then make the delivery pump continue to move, driving the slider a30 and the slider b31 to disengage from the docking pipe 28, so that the residual concrete in the grouting space and the recycled concrete in the collection space can be taken out of the docking pipe 28. The staff can recycle the concrete in the collection space and the grouting space, and then use the delivery pump to drive the slider a30 and the slider b31 to move into the docking pipe 28.

[0036] Then, the delivery pump is docked with the outermost docking nozzle 5 on the collection mechanism corresponding to the second group of grouting ports, so that the grouting pipe 13 on the second group of grouting ports performs the pouring operation. At the same time, the vibrating assembly on the first group of grouting ports prepares for work. First, the first group of grouting ports is opened by the driving assembly. At the same time, the pipe a 29 drives the gear c 24, the vibrating rod 26, and the sealing plate 25 to move close to the first group of grouting ports. The vibrating rod 26 extends through the first group of grouting ports into the concrete, and the sealing plate 25 moves to the first group of grouting ports to seal the first group of grouting ports, preventing the concrete from leaking into the inner side of the box body 14 during the vibration process. Then, the motor a 17 drives the gear column 22 to rotate. The gear column 22 drives the gear c 24 to rotate, and the gear c 24 drives the vibrating rod to rotate to stir the concrete, realizing the vibrating function of the concrete. And so on. When the grouting pipe 13 on the third group of grouting ports performs the pouring operation, the vibrating assembly on the second group of grouting ports prepares for work. When the grouting pipe 13 on the top formwork 1 starts to perform the pouring operation, the vibrating assembly on the third group of grouting ports prepares for work, thus realizing the vibrating function of concrete pouring without relying on external vibration equipment and improving the concrete vibrating efficiency.

[0037] After the vibration is completed, the driving assembly is used to move the pipe a 29 away from the grouting port and reset it, and at the same time drive the vibration assembly to reset. The driving assembly drives the two side sealing blocks 15 to move towards each other to realize the automatic closing function of the grouting port.

[0038] When the lining trolley moves to the tunnel turning point, under the guiding action of the guide wheels 7 and the driving action of the moving wheels a 10, the entire lining trolley can only move along the trend of the tunnel, realizing the automatic steering function of the lining trolley and facilitating the flexible movement of the lining trolley at the tunnel turning.

[0039] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
