[0025] Example: See Figure 1 and Figure 2 As shown, an adjustable tunnel secondary lining maintenance trolley of an embodiment is shown, which includes a trolley frame 1; a top guide rail 2 and a side guide rail 3 are respectively provided on the top and both sides of the trolley frame 1; a support frame 4 is movably installed in the top guide rail 2 and the side guide rail 3; a spray device is installed on the support frame 4, and the spraying range of the spray device includes the vertical circumferential direction above the ground; a guardrail 6 is connected to both ends of the top guide rail 2 or the side guide rail 3; and a water supply device is arranged on the trolley frame 1 for supplying water to the spray device.

[0026] In this embodiment, the support frame 4 is movably connected to the top guide rail 2 and the side guide rail 3 by installing rollers 42.

[0027] In this embodiment, the spray device includes a pair of spray rings 51 installed at the front and rear ends of the support frame 4, and a longitudinal pipe 52 connected to the spray rings 51 is connected between the two spray rings 51 at the top position. The two ends of the spray ring 51 are close to the ground, and a plurality of nozzles 55 are evenly arranged circumferentially on the surface of the spray ring 51.

[0028] In this embodiment, the water supply device includes a water tank 71 fixed on the trolley frame 1, a water supply hose 53 connected to the water tank 71, a turntable 72 for curling the water supply hose 53, and a booster pump 73 connected to the water tank 71, and the water supply hose 53 is connected to the longitudinal pipe 52.

[0029] In this embodiment, a first reinforcing rod 41 is provided in the support frame 4 , a second reinforcing rod 54 is connected between the support frame 4 and the spraying ring 51 , and a traveling wheel 11 is installed at the bottom of the trolley frame 1 .

[0030] The characteristics and functions of the present invention can be further understood through the following description.

[0031] The main problem solved by the utility model is that during the spraying of the secondary lining concrete, due to the mixed equipment in the tunnel and placed everywhere, the trolley is prone to collision with various equipment in the traditional spraying process through the movement of the trolley, and the secondary lining concrete needs to be sprayed in time after pouring. Therefore, the collision between the trolley and the equipment causes mutual interference in the work and affects the spraying effect, resulting in untimely spraying and delaying the project. And when the collision is more severe, it will cause damage to the equipment or the trolley, which is not worth the loss. Therefore, the utility model proposes an adjustable tunnel secondary lining maintenance trolley structure.

[0032] Continue to see Figure 1 and Figure 2As shown, the adjustable tunnel secondary lining maintenance trolley structure mainly includes a trolley frame 1, a top guide rail 2 is installed on the top of the trolley frame 1, a side guide rail 3 is installed on the side, and guardrails 6 are installed at both ends of the top guide rail 2 to prevent the spraying device from falling during movement. The support frame 4 is movably installed in the top guide rail 2 and the side guide rail 3 respectively through rollers 42, and at least one spray ring 51 is installed on the support frame 4. In this embodiment, two spray rings 51 are preferably used, and a plurality of spray heads 55 are evenly arranged on the spray ring 51. The two spray rings 51 are connected by installing a longitudinal pipe 52, and the longitudinal pipe 52 is connected to a water supply hose 53. The water supply hose 53 is connected to a water tank 71 installed on the side platform 12 of the trolley and is curled by a turntable 72. The length of the water supply hose 53 is adjusted during the movement of the support frame 4. A booster pump 73 is also installed in the water tank 71 to pressurize the water in the water tank 71, so that the water enters the longitudinal pipe 52 and the spray ring 51 through the water supply hose 53, and is finally sprayed out through the nozzle 55.

[0033] The spraying device of this embodiment can move longitudinally along the length direction of the top guide rail 2 and the side guide rail 3, and can perform spray maintenance on the tunnel within a certain range, thereby increasing the maintenance range at one time, and there is no need to frequently move the entire trolley. The top guide rail 2 and the side guide rail 3 are provided to make the support frame 4 more stable when walking. A guardrail 6 is provided, and a connecting rod for reinforcement can be provided between the spray rings 51 to ensure good structural stability. The other end of the water supply hose 53 is connected to the turntable 72, which can be arbitrarily retracted and extended in length, and then connected to the booster pump 73, and finally connected to the water tank 71.

[0034] In summary, the utility model realizes spraying of the secondary lining concrete by arranging a movable spraying device and a water supply device on the trolley frame, the water supply device supplies water to the spraying device, and the spraying ring moves in the guide rail, and the spraying direction is nearly 360° above the vertical horizontal plane. When the trolley is fixed, the mobile spraying can still be realized, which solves the problem that the trolley may collide with other equipment during movement in the tunnel.

[0035] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
