Description

Technical Field

[0001] The utility model relates to the technical field of tunnel trolleys, in particular to a tunnel secondary lining concrete curing trolley. Background Art

[0002] During the construction of long and large tunnels, after the second lining concrete is poured, it needs to be maintained for a certain period of time. If the maintenance is not timely, it will have an adverse effect on the hydration reaction of the concrete, resulting in insufficient strength and cracks. At present, the maintenance of the second lining concrete of the tunnel is mostly completed by manually operated water guns, which is inefficient and the maintenance quality is greatly affected by manual labor. There are also maintenance trolleys for the maintenance of the second lining concrete, but most of them are fixed in size and large in size. The trolley is loaded with a spraying device, and the spraying device itself is also large in size to achieve better and more comprehensive spraying maintenance of the second lining concrete in the tunnel. However, because the size of the trolley and the spraying device is large, it will collide with other engineering equipment in the tunnel during movement, causing great inconvenience. At the same time, the water mist after spraying will fall on the ground, making the ground slippery, which is easy to cause dangers such as slipping of workers. Therefore, there is an urgent need for a maintenance trolley that can not only realize the spraying maintenance of the second lining concrete of the tunnel, but also does not interfere with other engineering equipment and is convenient for workers to move around.

[0030] In this embodiment, Figure 4 As shown, the water supply system 7 includes a water tank 71 installed on the platform plate 14 , a booster pump 72 connected to the water tank 71 via a first water outlet pipe 73 , and a second water outlet pipe 74 connecting the booster pump 72 and the main water pipe 2 .

[0032] In this embodiment, Figure 1 As shown, a drainage board 10 with a groove is arranged on the outer side of the trolley frame 1, and the tail of the drainage board 10 has a longitudinal water collection groove 101 inclined downward.

[0033] In this embodiment, the plurality of legs 12 are connected to the upper longitudinal beam 16 at the location where the short cross beam 11 is connected, and are commonly connected to the lower longitudinal beam 17 at the location where the running wheels 13 are installed.

[0034] The characteristics and functions of the present invention can be further understood through the following description.

[0035] The maintenance trolley of the present embodiment mainly solves the problem that the traditional maintenance trolley has a large size and volume after the installation of the spray device, which is not convenient to move in the tunnel. In addition, other engineering equipment is stored everywhere in the tunnel. The maintenance trolley is prone to collision with other engineering equipment during movement, causing equipment damage; and the maintenance trolley is large in size, which is inconvenient for workers to move around at work, and the water mist from the spray device after spraying is easy to fall on the ground, making the ground slippery, and the workers are very likely to have dangerous accidents such as slipping. Therefore, the present embodiment proposes a maintenance trolley that can be used for workers to walk on and effectively reduces the slipperiness of the ground.

[0036] The maintenance trolley of this embodiment has square steel arches 3 arranged at equal intervals on the upper part of the trolley frame 1. A horizontal short crossbeam 11 is arranged on the inner side of the lower part, a platform plate 14 is laid on the upper part of the short crossbeam 11, and a diagonal brace 5 is arranged to support the waist of the square steel arch 3 and the end of the short crossbeam 11, and a short brace 6 is arranged to connect the square steel arch 3 horizontally to increase stability. A short diagonal brace 15 is arranged at the lower part of the short crossbeam 11 to support the support leg 12, and the lower part of the support leg 12 is a walking wheel 13.

[0037] The spray system includes a water tank 71 disposed on the platform plate 14. The first water outlet pipe 73 of the water tank 71 is connected to the booster pump 72. After the water is pressurized by the booster pump 72, it enters the main water pipe 2 disposed in the middle section of the trolley through the second water outlet pipe 74. The main water pipe 2 is arched like the square steel arch frame 3. The main water pipe 2 and the square steel arch frame 3 are connected in the longitudinal direction through the branch pipe 4 welded on the square steel arch frame 3. The branch pipes 4 are evenly spaced along the annular direction. Each branch pipe 4 is connected to the main water pipe 2 in the middle. Atomizing spray heads 41 are evenly spaced longitudinally on each branch pipe 4 to spray and maintain the secondary lining concrete.

[0038] A drainage board 10 is arranged in a circular manner inside the spray system to prevent the spray water from directly spraying onto the road inside the tunnel after gathering, which would have a negative impact on the construction workers and the environment. The drainage board 10 is not flat, but has a concave groove (such as Figure 1 and Figure 2 As shown in ), it is beneficial for the water flow to converge and flow down. A longitudinal water collection groove 101 is provided at the lower end of the drainage plate 10. After the water converges, it is discharged downward from the rear end of the trolley to the drainage ditch on both sides of the tunnel.

[0039] The maintenance trolley of this embodiment has a simple structure, regular pipelines, and uniform spraying, which ensures the quality of maintenance. At the same time, it also avoids the impact of water mist on construction personnel and the environment in the tunnel. The walking space inside the trolley is 100 large for construction vehicles and personnel to pass through, which has little impact on other engineering equipment and construction operations.

[0040] In summary, the utility model has a trolley frame separated on both sides, and an arched spray device is arranged above the trolley frame to form a passage for workers to walk between the trolley frames, which is convenient for workers to walk back and forth during work, and other engineering equipment can be placed in the passage, and there will be no interference or collision with other engineering equipment during the movement of the trolley. Drain boards are arranged on both sides of the trolley to facilitate the water mist after spraying to be gathered into water through the drainage boards and then discharged to the drainage ditches on both sides of the tunnel. The maintenance trolley of the utility model has a simple structure, regular pipelines, and uniform spraying, which ensures the quality of maintenance. At the same time, it also avoids the impact of water mist on construction personnel and the environment in the tunnel. The inner side of the trolley leaves a large space for construction vehicles and personnel to pass through, which has little impact on other construction operations.
