[0002] With the vigorous development of infrastructure construction, the number of infrastructure buildings is increasing. In the construction process of some buildings, the quality requirements are very strict. For example, structural concrete requires more than seven days of maintenance after pouring. Secondary lining is a relatively common maintenance method. If the secondary lining is not maintained in time, cracks will appear on the concrete surface, causing serious consequences.

Both the inclined rod and the vertical rod are elastic, so they deform under the action of external force and change the spray posture. By setting the limit plate, the bottom end of the vertical rod can be supported to prevent it from sliding to the concrete surface at the bottom, and at the same time, a reaction force is provided for the outward expansion and deformation of the inclined rod.

When the supporting sleeve moves downward, due to the limiting effect of the retaining sleeve and the supporting effect of the limiting plate, the oblique rod part bends outward as close as possible to the secondary lining of the tunnel, driving the spray mechanism to perform spray enclosure, and by setting the cooperation of the limiting block and the limiting convex strip, the limitation of the vertical rod part is further ensured to prevent it from slipping out of the limiting sleeve.

[0021] Preferably, the sliding assembly includes a limiting sliding sleeve arranged on the side wall of the water tank, and the L-shaped rod is slidably arranged inside the limiting sliding sleeve.

[0025] By adopting the above technical solution: the driving gear is driven by a servo motor. After the driving gear rotates, it can drive the L-shaped rods on the upper and lower sides to move relative to each other through the rack, so that the vertical rod part can be pushed outward. At the same time, the supporting sleeve can be driven downward by the pulling member, and the spraying height can be adjusted while the spraying range is expanded outward, so that it fits the inner wall of the tunnel as much as possible, and the lining maintenance of the entire tunnel side wall can be completed in one spraying.

[0026] Preferably, the spray mechanism includes a spray soft belt arranged on the two elastic rods and the top of the support sleeve, and the spray soft belt is connected to the connecting pipe.

[0027] By adopting the above technical solution: the connecting pipe can be a telescopic hose, and the water pressurized by the pressure pump is sent to the spray belt, which is provided with fine holes. After the water is sprayed out through the fine holes, it forms water mist, which can complete the maintenance of the secondary lining of the tunnel.

[0028] Preferably, the linkage deformation mechanism includes a column arranged on the water tank, and the upper end of the column is provided with a top connecting portion with a curved surface.

[0029] By adopting the above technical solution: when the support sleeve moves downward, the oblique rod portion is compressed, and the oblique rod portion can be pushed outward through the column and the top connection portion to form an arc shape as much as possible.

[0032] The working principle and beneficial effects of the present invention are:

[0033] 1. Driven by the driving mechanism, the traveling wheels can move, thereby driving the entire vehicle body to move. The water tank on the vehicle body is used to store spray water. The water can be pressurized by the pressurizing mechanism, and then sprayed out through the spraying mechanism to the secondary lining of the inner wall of the tunnel to complete the maintenance. The spraying range of the spraying mechanism can be adjusted by setting an adjustment mechanism to adapt to the secondary lining surface of the tunnel. The shape of the spraying mechanism can be changed in a linkage manner through the linkage deformation mechanism to make it more fit the secondary lining surface of the tunnel, so as to better complete the spray maintenance. This technical solution can complete maintenance more accurately and conveniently by walking from one side of the tunnel to the other side, thereby improving the maintenance efficiency.

[0034] 2. The height adjustment component in the present invention can be adjusted according to the overall height of the tunnel, and the diameter expansion component can expand the spray mechanism outward so that it can better fit the inner wall of the tunnel, thereby achieving a better spraying effect. Driven by the collaborative power component, the height adjustment component and the diameter expansion component can move synchronously to adjust to a posture that is as compatible as possible with the inner wall of the tunnel.

[0035] 3. The setting of the telescopic part makes the spray height adjustable. By setting the elastic rod, it can drive the spray mechanism to deform, so that the spray position is more in line with the inner wall of the tunnel. The inclined rod and the vertical rod are elastic, so they deform under the action of external force and change the spray posture. By setting the limit plate, the bottom end of the vertical rod can be supported to prevent it from sliding onto the concrete surface at the bottom, and at the same time, it also provides a reaction force for the outward expansion and deformation of the inclined rod.

[0036] 4. By setting a sliding assembly, the two L-shaped rods can be limited, so that the two L-shaped rods can move relatively parallel to each other, thereby relatively contracting and pushing the two L-shaped rods outward. A retaining sleeve is set at the end of the L-shaped rod, and the retaining sleeve is set on the vertical rod part, which can relatively fix the vertical rod part so that the vertical rod part can slide up and down along the retaining sleeve. When the supporting sleeve moves downward, due to the limiting effect of the retaining sleeve and the supporting effect of the limiting plate, the oblique rod part bends outward as close as possible to the secondary lining of the tunnel, driving the spray mechanism to spray enclosure. By setting the cooperation of the limiting block and the limiting convex strip, the limitation of the vertical rod part is further ensured to prevent it from slipping out of the limiting sleeve.

[0037] 5. When the support sleeve moves downward, the trigger block hijacks the passive block, causing the passive block to move outward, thereby driving the retaining rod to move outward. The top connection part on the retaining rod can push the inclined rod part outward to make it as arc-shaped as possible, so that it fits the inner wall of the tunnel as much as possible, further improving the spray maintenance effect.

The shape of the spraying mechanism 500 can be linked through the linkage deformation mechanism 700 to make it more fit the secondary lining surface of the tunnel, so that the spraying maintenance can be better completed. This technical solution can complete maintenance more accurately and conveniently by walking from one side of the tunnel to the other, thereby improving maintenance efficiency.

[0071] On the basis of this basic technical solution, the rest is the same as Example 1, and the difference from Example 1 is as follows: in order to make the deformation amplitude of the inclined rod portion 611 larger and to be able to fit more closely to the secondary lining of the inner wall of the tunnel, the linkage deformation mechanism 700 in this embodiment includes a retaining column 730 arranged on the water tank 300, and a top connecting rod 731 is passed through the retaining column 730, and a top connecting portion 720 is provided at one end of the top connecting rod 731 close to the inclined rod portion 611, and a driven block 732 with an inclined surface is provided at the other end of the top connecting rod 731, and a touch block 733 with an inclined surface is provided on the support sleeve 615. When the touch block 733 moves downward, it pushes the driven block 732 to move outward, and the top connecting portion 720 touches the inclined rod portion 611 to push the inclined rod portion 611 outward.

[0072] When the support sleeve 615 moves downward under the pull of the wire rope 634, the trigger block 733 hijacks the passive block 732, causing the passive block 732 to move outward, thereby driving the retaining rod to move outward. The top connection portion 720 on the retaining rod can push the inclined rod portion 611 outward to make it as arc-shaped as possible, thereby fitting the inner wall of the tunnel as much as possible, further improving the spray maintenance effect.

[0073] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
