Description

Technical Field

[0001] The utility model relates to the technical field of tunnel lining maintenance, and particularly relates to a tunnel lining maintenance device. Background Technique

[0002] The tunnel lining is a permanent support structure built along the periphery of the tunnel body with materials such as reinforced concrete to prevent the surrounding rock from deforming or collapsing. The tunnel lining mainly consists of several parts including an arch ring, side walls, invert, and floor. To drain the water in the tunnel, a drainage ditch (central drainage ditch or side ditch) is also provided in the tunnel. Common lining forms include shotcrete lining, shotcrete with rock bolt lining, and composite lining. In most cases, composite lining is adopted. Tunnel linings are generally divided into two types: hard linings and soft linings. These two types are mainly distinguished according to the materials used and the structural characteristics.

[0003] In tunnel construction, the construction of the tunnel lining is a key step to ensure the stability and durability of the tunnel structure. However, in the initial stage of tunnel lining construction, proper maintenance is equally crucial. Since the tunnel lining usually adopts an arched design, this special shape poses certain challenges to the water spraying maintenance work. During the traditional water spraying maintenance process, workers need to manually operate the water spraying device to ensure that the water mist can evenly cover the arched surface of the tunnel lining. However, this method is not only inefficient but also greatly increases the workload of the workers. Due to the arched structure of the tunnel lining, workers need to continuously adjust the angle and position of the water spraying device to ensure that each part can receive sufficient water spraying maintenance. This traditional water spraying maintenance method not only takes time and effort but also makes it difficult to ensure that each part of the tunnel lining can receive uniform maintenance. Therefore, this method is not conducive to the effective water spraying maintenance work of the tunnel lining. Therefore, it is necessary to provide a tunnel lining maintenance device to solve the above technical problems. Content of the Utility Model

Detailed Description of the Embodiment

[0022] The following further elaborates on the present utility model in detail with reference to the embodiments:

[0023] As Figures 1-4As shown in the figure, the utility model provides a tunnel lining maintenance device, which includes a bottom plate 1, a lifting assembly 3, side plates 5 and a water outlet assembly. A plurality of lifting assemblies 3 are fixedly installed at the four corners of the upper surface of the bottom plate 1 at equal intervals. The tops of the plurality of lifting assemblies 3 are respectively fixedly connected to the four corners of the lower surface of the top plate 4. Two side plates 5 are symmetrically and fixedly installed at both ends of the upper surface of the top plate 4. A plurality of cross bars 6 are fixedly installed at equal intervals between the two side plates 5. A plurality of guide pipes 7 are fixedly installed at equal intervals on the plurality of cross bars 6. Nozzles 8 are fixedly installed at equal intervals on the outer surfaces of the plurality of guide pipes 7. Two cross pipes 9 are symmetrically and fixedly installed on the upper surface of the top plate 4, and one side of the two cross pipes 9 is fixedly connected to the end of the guide pipe 7. The water outlet assembly is fixedly installed on the upper surface of the bottom plate 1, and the output end of the water outlet assembly is fixedly connected to both ends of the cross pipe 9.

[0024] It should be noted that when the device is needed to spray water for maintaining the tunnel lining, at this time, the staff pushes the device into the tunnel. At this time, the water outlet assembly introduces the water inside it into the cross pipe 9, then sends it into the guide pipe 7 through the cross pipe 9, and then sprays it onto the tunnel lining through the nozzles 8 on the guide pipe 7, so that the water for maintenance can be sprayed more evenly and quickly on the surface of the tunnel lining. In order to adjust the distance between the nozzle 8 and the surface of the tunnel lining, the lifting assembly 3 can adjust the height of the top plate 4, thereby increasing the convenience of using the device and making it more convenient for the staff to use this device to maintain the tunnel lining.

[0025] As Figure 1 and Figure 2 shown, universal wheels 2 are fixedly installed at the four corners of the lower surface of the bottom plate 1.

[0026] It should be noted that the setting of the universal wheels 2 can increase the mobility of the device, making the device more convenient to use.

[0027] As Figure 1 、 Figure 2 and Figure 3 shown, the water outlet assembly includes a water storage tank 10. The water storage tank 10 is fixedly installed at the center of the upper surface of the bottom plate 1. A water pump 11 is fixedly installed at the top of the water storage tank 10. The input end of the water pump 11 is fixedly connected to one end of a connecting pipe 12, and the end of the connecting pipe 12 far from the water pump 11 is fixedly connected to the top of the water storage tank 10. The output end of the connecting pipe 12 is fixedly installed with a water outlet pipe 13. One side of the water storage tank 10 is fixedly installed with a water inlet pipe 14. Installation frames 15 are fixedly installed at both ends of the upper surface of the bottom plate 1. Both ends of the two cross pipes 9 are fixedly installed with conduits 16. One end of the plurality of conduits 16 far from the cross pipes 9 is fixedly connected to one side of the installation frame 15. The ends of the water outlet pipe 13 and the water inlet pipe 14 far from the connecting pipe 12 are respectively fixedly connected to one side of the two installation frames 15.

[0028] It should be noted that: when using the water outlet component to input water into the transverse pipe 9, the water pump 11 starts to work. At this time, the water pump 11 draws out the water inside the water tank 10 through the connecting pipe 12, and transports it to the water outlet pipe 13 through the water pump 11. The water outlet pipe 13 transports the water to the mounting frame 15, and cooperates with the conduit 16 to transport the water to the transverse pipe 9, and then sprays the water evenly on the surface of the tunnel lining through the guide pipe 7 and the nozzle 8, so as to better maintain it. In addition, the other end of the transverse pipe 9 transports the excess water to the inside of the water tank 10 again through the conduit 16, the mounting frame 15 and the water inlet pipe 14.

[0029] like Figure 1 and Figure 2 As shown, a mounting cavity is defined inside the top of the mounting bracket 15 .

[0030] It should be noted that the mounting cavity at the top of the mounting frame 15 facilitates the connection of the conduit 16 with the water outlet pipe 13 and the water inlet pipe 14, so that the flow channel inside the device is connected, thereby increasing the stability of the device when in use.

[0031] like Figure 1 and Figure 2 As shown, the conduit 16 is provided as a hose.

[0032] It should be noted that the conduit 16 provided with the hose can increase the connection fit between the cross pipe 9 and the mounting bracket 15 , and the provision of the hose can cooperate with the lifting assembly 3 to perform lifting work, thereby increasing the stability of the device during use.

[0033] like Figure 4 As shown, the lifting assembly 3 includes a base 17, and several bases 17 are arranged in an upper and lower manner. An X-shaped frame 18 is provided between the several bases 17, and one end of the several X-shaped frames 18 is rotatably connected to one end of the base 17 respectively. A guide frame 20 that slides with the X-shaped frame 18 is symmetrically fixedly installed on one side of the several bases 17, and the upper surface of the several bases 17 is rotatably connected to the hydraulic cylinder 19, and the principle of the several hydraulic cylinders 19 is rotatably connected between one end of the base 17 and the X-shaped frame 18.

[0034] It should be noted that: when the height of the top plate 4 needs to be adjusted, the hydraulic cylinder 19 starts to work, and the X-shaped frame 18 is unfolded by the hydraulic cylinder 19. One end of the X-shaped frame 18 is rotatably connected to the base 17, and the other end is slidably connected to the base 17. As the X-shaped frame 18 is unfolded, the distance between the bases 17 is expanded, so that the position of the top plate 4 can be adjusted.

[0035] like Figure 4 As shown, one end of the plurality of X-shaped frames 18 is provided with a cam that is slidably engaged with the guide frame 20.

[0036] It should be noted that the bumps at the ends of the X-shaped frame 18 increase the sliding fit degree between the X-shaped frame 18 and the guide frame 20.

[0037] As Figure 4 shown, one end of the X-shaped frame 18 is provided with a mounting rod for mounting and cooperating with the hydraulic cylinder 19.

[0038] It should be noted that the mounting rod at one end of the X-shaped frame 18 can increase the mounting fit degree between the hydraulic cylinder 19 and the X-shaped frame 18.

[0039] Next, the working principle of the tunnel lining maintenance device will be specifically described.

[0040] As Figures 1-4 shown, when the device is needed to spray water for maintaining the tunnel lining, at this time, the staff pushes the device into the tunnel. At this time, the water outlet assembly introduces the water inside it into the cross pipe 9, and the water pump 11 starts to work. At this time, the water pump 11 pumps out the water inside the water storage tank 10 through the connecting pipe 12, transports it through the water pump 11 to the water outlet pipe 13, and the water outlet pipe 13 transports the water into the mounting frame 15. Cooperating with the conduit 16, the water is transported into the cross pipe 9, and then the water is evenly sprayed on the surface of the tunnel lining through the guide pipe 7 and the nozzle 8, so as to better maintain it. In addition, the other end of the cross pipe 9 transports the excess water back into the water storage tank 10 through the conduit 16, the mounting frame 15 and the water inlet pipe 14, sends it into the guide pipe 7 through the cross pipe 9, and then sprays it on the tunnel lining through the nozzle 8 on the guide pipe 7, so that the water for maintenance can be sprayed on the surface of the tunnel lining more evenly and quickly. In order to adjust the distance between the nozzle 8 and the surface of the tunnel lining, the lifting assembly 3 can adjust the height of the top plate 4. The hydraulic cylinder 19 starts to work, expands the X-shaped frame 18 through the hydraulic cylinder 19. One end of the X-shaped frame 18 is rotatably connected to the base 17, and the other end is slidably connected to the base 17. As the X-shaped frame 18 expands, the distance between the bases 17 is enlarged, so that the position of the top plate 4 can be adjusted, and thus the use convenience of the device can be increased, and it is more convenient for the staff to use this device to maintain the tunnel lining.

[0041] The above has generally described the present utility model in detail, but based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are all within the protection scope of the present utility model.
