Description

Technical Field

[0001] The utility model relates to the technical field of concrete maintenance, in particular to a spray maintenance trolley which is specially used in tunnels and can adjust the spray position. Background Art

[0002] During the tunnel construction process, the concrete poured on the inner wall needs to be sprayed and cured. The conventional maintenance method is to spray manually or use a maintenance trolley. For example, the tunnel secondary lining maintenance and dust removal spray trolley disclosed in CN 204149309 U includes a door-shaped load-bearing frame, a walking device and a spray assembly; the spray assembly includes an arched water spray pipe and a water collection tank; the lower end of the arched water spray pipe is connected to the pressurized water pump and the water storage tank in turn; the water collection tank is connected to the water storage tank through a recovery pipe. However, due to the large size of the trolley, high equipment cost, and limited space in the tunnel, other equipment cannot be brought in, and it is not suitable for tunnels with large size differences.

[0003] Manual operation requires multiple people, which is labor-intensive and prone to uneven spraying. Usually, multiple nozzles are fixed on the pipeline for water spraying maintenance, but it is easy to cause serious attenuation of water spraying pressure, unbalanced pressure, and uneven maintenance.

[0006] The horizontal telescopic bracket includes a sliding rod, a vertical rod and a transverse rod, the vertical rod is fixed on the vehicle body, and the transverse rod is installed on the top of the vertical rod through a rotating connection structure; a plurality of locking rings are arranged on the transverse rod at intervals along its extension direction, and the sliding rod passes through all the locking rings at the same time and is fixed by the locking bolts on the locking rings.

[0007] In the above scheme: the spray assembly includes a spray head.

[0008] In the above scheme: the shape of the spray nozzle is fan-shaped.

[0009] In the above scheme: the vertical rod is fixed to the front side of the vehicle body, the rotating connection structure is a bolt roller bearing, the bolt roller bearing is fixed to the top of the vertical rod through a hoop, and the bolt of the bolt roller bearing is arranged upward, the transverse rod is provided with a through hole for the bolt to pass through, and is fixed by a nut; a pad is arranged between the transverse rod and the sliding rod. The structure is simple and the arrangement is reasonable. Compared with the rotating sleeve, the bolt roller bearing is more stable and not easy to fall out.

[0010] In the above scheme: the vertical rod is a round rod, and the transverse rod and the sliding rod are both square rods. The vertical rod is set as a round rod, which is convenient for fixing and rotating. The transverse rod and the sliding rod are both square rods, which can ensure the direction of the fixed column and prevent the fixed column from rotating, thereby ensuring the installation stability of the spray assembly.

[0011] In the above scheme: the vehicle body is equipped with tracks laid in the tunnel to ensure the moving direction of the vehicle body, thereby ensuring that the spray assembly is always on the center line of the tunnel.

[0012] In the above scheme: the middle part of the water pipe of the water supply system is fixed on the transverse rod, and the booster pump is fixed on the top of the vehicle body.

[0013] In summary, the beneficial effects of the utility model are as follows: the horizontal telescopic bracket can adjust the position of the fixed column and the spray assembly to ensure that the spray assembly is on the center line of the tunnel, ensuring the spray effect, and can be applied to tunnels of different sizes, with a wide range of applications. The rotating horizontal telescopic bracket can rotate the spray assembly to the wall, which can make more space for passing equipment. It only occupies half of the space on the tunnel, reducing the occupied space, and the spray bracket can also be rotated to make room for equipment to pass, which is convenient to avoid, and only needs to rotate the horizontal telescopic bracket.

[0017] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0018] Embodiment 1

[0019] like Figure 1 , 2As shown, a spray maintenance trolley specially used in tunnels and capable of adjusting the spraying position comprises a vehicle body 1 and a track 1a laid in the tunnel, and the vehicle body 1 moves on the track 1a. The moving direction of the vehicle body 1 is ensured, so that the spray assembly is always on the center line of the tunnel. The track 1a is set close to one side of the tunnel, leaving as much passage space as possible, and the setting is reasonable.

[0020] A horizontal telescopic bracket 2 is rotatably arranged on the vehicle body 1. The horizontal telescopic bracket 2 includes a slide bar 2c, a vertical bar 2a and a transverse bar 2b. The vertical bar 2a is fixed on the vehicle body 1, and the transverse bar 2b is installed on the top of the vertical bar 2a through a rotation connection structure. A plurality of locking rings 2f are arranged at intervals on the transverse bar 2b along its extension direction. The slide bar 2c passes through all the locking rings 2f at the same time and is fixed by the locking bolts on the locking rings 2f.

[0021] Specifically, the vertical rod 2a is fixed to the front side of the vehicle body 1, and the rotating connection structure is a bolt roller bearing 10. The bolt roller bearing 10 is fixed to the top of the vertical rod 2a by a clamp 11, and the bolt of the bolt roller bearing 10 is set upward. The structure is simple and the setting is reasonable. Compared with the setting of the rotating sleeve, the setting of the bolt roller bearing 10 makes the connection more stable and not easy to fall out. The transverse rod 2b is provided with a through hole for the bolt to pass through, and is fixed by a nut. A pad 2e is provided between the transverse rod 2b and the sliding rod 2c to make room for installing the bolt roller bearing 10 and the nut.

[0022] The vertical rod 2a is a round rod, and the transverse rod 2b and the slide rod 2c are both square rods. The transverse rod 2b and the slide rod 2c are both square rods, which can ensure the direction of the fixed column 2d and prevent the fixed column 2d from rotating, thereby ensuring the installation stability of the spray assembly.

[0023] The end of the horizontal telescopic bracket 2 is provided with a fixed column 2d extending upward, and the top of the fixed column 2d is provided with a spray assembly.

[0024] The spray assembly includes a spray head 4, which sprays in a fan-shaped shape with a wide range, ensuring that the spray ranges of adjacent spray heads 4 overlap, avoiding spray dead angles, and ensuring the spray effect. The spray head 4 is connected to a water supply system, which includes a water pipe 3a and a booster pump 3d. A water tank is provided on the vehicle body 1, and the booster pump 3d is connected to the water tank. The middle part of the water pipe 3a is fixed on the transverse rod 2b, and the booster pump 3d is fixed on the top of the vehicle body.

[0025] Embodiment 2

[0026] like Figure 3As shown, the difference between this embodiment and the first embodiment is that the spray assembly is provided with a plurality of spray heads 4 and a spray bracket 4a for mounting the spray heads. The bottom of the spray bracket 4a is fixedly mounted on the fixed column 2d, and the top of the spray bracket 4a is arc-shaped, so that the spray bracket 4a is fan-shaped as a whole. The plurality of spray heads 4 are arranged in the spray bracket 4a in sequence from left to right, and each spray head 4 is connected to the water pipe 3a of the water supply system.
