[0015] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0016] like Figure 1-2 As shown, a tunnel spray maintenance trolley includes two portal frames 1 connected front and rear, and the two portal frames 1 are connected by two left and right connecting rods 2. A base frame 3 is arranged at the bottom of the portal frame 1, and the top of the base frame 3 is plugged into the bottom of the portal frame 1 through a row of mounting holes arranged at intervals up and down to achieve height-adjustable installation.

[0017] A water tank 4 is installed on the bottom frame 3, and a delivery pump 5 is installed on the top of the water tank 4. Vertical rods 6 are installed symmetrically on the top of the portal frame 1 by bolts, so that L-shaped frames are formed on the left and right sides of the portal frame 1, and an arc frame 7 is plugged into each L-shaped frame. The upper side of the portal frame 1 is plugged with an arc frame 7, and the plug-in is connected by bolts. The front end of the arc frame 7 is evenly fan-shaped with a nozzle 8, and the nozzle 8 is connected to a first water delivery pipe 9.

[0018] Preferably, a driving wheel 10 is installed at the bottom of the chassis 3. A liquid level gauge 11 is provided at the front end of the water tank 4 to facilitate the operator to observe the liquid level inside the water tank 4.

[0019] Limit protection bars 12 are provided on both sides of the portal frame 1 to prevent the trolley from colliding with the inner wall of the tunnel and causing damage to the trolley.

[0020] The delivery pump is connected to a second water delivery pipe 13, the upper side of which is embedded in the portal frame 1 and communicated with the first water delivery pipe 9. The second water delivery pipes 13 are connected to the water tanks 4 on the corresponding sides, and the number of the first water delivery pipes 9 corresponds to the number of the nozzles 8 on the corresponding sides, and all the first water delivery pipes 9 on the same side share the same second water delivery pipe 13 for water supply.

[0021] It should be noted that before the spraying maintenance process is carried out inside the tunnel, the vertical rod 6 and the arc frame 7 matching the curvature of the upper side of the tunnel are first installed on the top of the portal frame 1, and the spray head 8 is fixed to the front end of the arc frame 7 by bolts. Then the operator can adjust the height of the portal frame 1 according to the use requirements, and after the adjustment is completed, the height of the portal frame 1 is fixed by using the mounting hole and the latch;

[0022] Then, the driving wheel 10 can be used to move the spray maintenance trolley inside the tunnel. At the same time, the delivery pump 5 starts to operate, extracts spray water from the water tank 4, and transports it through the second delivery water pipe 13 and the first delivery water pipe 9, and finally sprays it out through the nozzle 8, so as to complete the spray maintenance operation inside the tunnel;

[0023] After the spray curing is completed, the lower side of the portal frame 1 can be retracted to the top of the bottom frame 3, and the arc frame 7 and the vertical rod 6 can be removed, so that the overall volume of the trolley can be greatly reduced, making it easier for operators to move the trolley;

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
