[0035] Example

[0036] The utility model will be further described below in conjunction with the accompanying drawings.

[0037] like Figure 1-3 As shown, this embodiment provides an energy-saving tunnel spraying maintenance trolley, comprising:

[0038] A trolley body 1, the top of which is connected to an arc-shaped spray pipe 2, on which a plurality of spray heads 3 are evenly arranged, the spray pipe 2 is connected to a water outlet of a water tank 6, and the spray head 3 is preferably an atomizing spray head;

[0040] The spray recovery box 5 is connected to the bottom ends of both sides of the trolley body 1 and is located below the water collecting tank 4. The top opening of the spray recovery box 5 is connected to a primary filter screen plate 7, and the spray recovery box 5 is connected to the water inlet end of the water tank 6.

[0041] The bottom of the trolley body 1 is connected with running wheels 8 , and the trolley body 1 is moved flexibly along the inside of the tunnel through the running wheels 8 .

[0042] The water tank 6 is connected to the top of the trolley body 1, the trolley body 1 is connected to the spray pipe 2 through the water outlet pipe 9, the spray recovery tank 5 is connected to the water tank 6 through the return pipe 10, and water pumps are provided on the water outlet pipe 9 and the return pipe 10. The first water pump is used to pump the spray water in the water tank 6 into the spray pipe 2, and the second water pump is used to circulate the spray water recovered in the spray recovery tank 10 to the water tank 6.

[0043] The water collecting trough 4 is arranged in an arc shape, and the water collecting trough 6 is arranged concentrically with the spray pipe 2. The water collecting trough 4 is arranged in an arc shape to adapt to the arc-shaped inner wall of the tunnel and the arc-shaped spray pipe 2, so that the spray water can be more fully collected and the spray water can flow quickly along the water collecting trough 4 to the spray recovery box 5.

[0044] Among them, a filter screen 11 is arranged at one end of the return pipe 10 connected to the spray recovery box 5. The filter screen 11 filters the spray water entering the return pipe 10 to prevent particles in the spray water from clogging the pipeline.

[0045] The bottom wall of the spray recovery box 5 is provided with an inclined surface 12 , and the side of the inclined surface 12 away from the return pipe 10 is higher than the side close to the return pipe 10 .

When in use, the trolley body 1 is moved to the inside of the tunnel, the water pump is started to pump the spray water in the water tank 6 into the spray pipe 2, and a uniform spray is formed through the nozzle 3, which is sprayed on the inner wall surface of the tunnel to spray and maintain the tunnel. During the spraying process, part of the spray water falls back, and the falling spray water is collected by the water collection tank 4 and the spray recovery box 5. The spray water collected by the water collection tank 4 flows downward along its inner wall to the spray recovery box 5; when the spray water enters the spray recovery box 5, the spray water is initially filtered by the primary filter plate 7 to filter out most of the mixed particles and impurities; the spray water is stored in the spray recovery box 5 and flows along the inclined surface 12 to the return pipe 10; after passing through the filter screen 11, it enters the return pipe 10 and circulates the spray water to the water tank 6 through the pump body.

[0048] The beneficial effects of the utility model are:

[0049] The present embodiment provides an energy-saving tunnel spray maintenance trolley, which adopts a water collection tank 4 and a spray recovery box 5 to collect spray water, and recycles it after filtering, thereby reducing the loss of spray water and achieving energy saving and green construction; a primary filter screen plate 7 is arranged in the spray recovery box 5 to perform pre-filtration before reflux. The primary filter screen plate 7 has a relatively large area and can filter a larger amount of spray water, thereby reducing the load of the filter screen 11 on the reflux pipe 10, eliminating the need for frequent replacement and cleaning of the filter screen 11, thereby improving the practicality of the spray maintenance trolley.

[0050] like Figure 3-5 As shown, in one embodiment, two sets of filter screen vibration components are arranged on both the front and rear sides of the spray recovery box 5, and the filter screen vibration components include:

[0051] A first support 13 and a second support 14, both of which are connected to the side wall of the spray recovery box 5;

[0052] The first connecting rod 15, the second connecting rod 16 and the third connecting rod 17, the first connecting rod 15 is hinged on the first support 13, the second connecting rod 16 is hinged on the second support 14, and the third connecting rod 17 is hinged between the first connecting rod 15 and the second connecting rod 16; the hinge shaft of the first connecting rod 15 is connected to the driving motor.

[0053] A third support 18, the third support 18 is connected to the bottom end of the primary filter screen plate 7;

[0054] The fourth connecting rod 19 has a bottom end connected to the middle of the third connecting rod 17 and a top end hinged to the third support 18 .

[0055] The second support 14 is located above the first support 13 on a side away from the return pipe 10 .

[0056] The length of the second connecting rod 16 is greater than that of the first connecting rod 15 , and the first connecting rod 15 , the second connecting rod 16 , the third connecting rod 17 and the first support 13 and the second support 14 form a crank rocker mechanism.

[0057] Among them, a guide plate 20 is connected to the top of the side of the spray recovery box 5 away from the return pipe 10, and a dust collecting box 21 is connected to the side of the spray recovery box 5 away from the return pipe 10. The dust collecting box 21 and the spray recovery box 5 are detachably arranged, and the guide plate 20 is located below the primary filter plate 7 and the bottom end extends toward the dust collecting box 21.

[0058] The working principle and beneficial effects of this embodiment are as follows:

[0059] A filter vibration assembly is arranged in the spray recovery box 5. Taking the spray recovery box 5 on the left as an example, when in use, the driving motor is started to drive the first connecting rod 15 to rotate counterclockwise, and the first connecting rod 15 drives the third connecting rod 17 to rotate, and drives the second connecting rod 16 to rotate at the same time, and the first connecting rod 15, the second connecting rod 16, the third connecting rod 17 and the first support 13 and the second support 14 form a crank rocker mechanism; that is, as the first connecting rod 15 rotates, the second connecting rod 16 is driven to swing back and forth, and at the same time, the third connecting rod 17 drives the third support 18 to move through the fourth connecting rod 19, so that the primary filter screen plate 7 makes a parabolic motion from the lower right to the upper left; the particulate matter filtered out by the spray water is located on the primary filter screen plate 7, and with the cyclic parabolic motion of the primary filter screen plate 7, the particulate matter is cyclically thrown to the left until it falls down after the edge of the primary filter screen plate 7, and enters the dust collecting box 21 along the guide plate 20, so as to facilitate subsequent centralized treatment.

[0060] Through the above-mentioned structural design, a filter vibration component is arranged in the spray recovery box 5 to realize the driving of the primary filter screen plate 7, so that it performs a cyclic parabolic motion, and the filtered mud and other particulate matter are scattered and moved to the edge of the primary filter screen plate 7 for discharge and collection, thereby realizing the self-cleaning of the primary filter screen plate 7, reducing the frequency of manual cleaning of the primary filter screen plate 7, and extending the service life of the primary filter screen plate 7; at the same time, the primary filter screen plate 7 circulates, and the spray water is separated from the primary filter screen plate 7 under the action of inertia, thereby reducing the adhesion of the spray water on the primary filter screen plate 7, and the recovery rate of the spray water is higher.

[0061] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
