Detailed implementation mode
[0022] The following specific embodiments illustrate the implementation modes of the present invention. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0023] As Figure 1 shown, a highway bridge maintenance spray device is mainly used for the spray maintenance of the anti-collision wall of the viaduct. Specifically, it includes a base 1, on which a water tank 2 and a cross bar 3 are installed, and the height of the cross bar 3 is adjustable;
[0024] Anti-collision wall spray mechanisms are installed at both ends of the cross bar 3. The anti-collision wall spray mechanism includes two vertical bars 4 opposite to each other left and right, and the distance between the two vertical bars 4 is adjustable. Anti-collision wall spray pipes 5 are installed on the opposite surfaces of the two vertical bars 4;
[0025] A water distribution pipe 7 is installed in the middle of the cross bar 3, a water pump 8 is installed on the top of the water tank 2, the water inlet end of the water pump 8 is connected to the bottom of the inner cavity of the water tank 2, one end of the water distribution pipe 7 is connected to the water outlet end of the water pump 8 through a water supply pipe 9, and the other end of the water distribution pipe 7 is respectively connected to the four anti-collision wall spray pipes 5 through four hoses 6;
[0026] By adjusting the distance between the two vertical bars 4 to be suitable for anti-collision walls of various widths, and then by adjusting the height of the cross bar 3, the two vertical bars 4 are lowered, so that the two vertical bars 4 are symmetrically distributed on both sides of the anti-collision wall. Then, the water pump 8 pumps the clear water in the water tank 2, and the clear water is transmitted to the anti-collision wall spray pipe 5 through the water supply pipe 9, the water distribution pipe 7 and the hose 6, and finally sprayed out by the anti-collision wall spray pipe 5, so as to spray and maintain the anti-collision wall.
[0027] Specifically, as Figure 1 and Figure 2 shown, nozzles are installed on the side of the anti-collision wall spray pipe 5 away from the vertical bar 4. The number of nozzles is multiple and evenly distributed along the length direction of the vertical bar 4. When the cross bar 3 is lowered to the lowest position, the anti-collision wall spray pipe 5 is still higher than the anti-collision wall, so that the nozzles on the top side of the anti-collision wall spray pipe 5 can spray the top of the anti-collision wall.
[0028] Specifically, asFigure 1 As shown, the sub-water pipe 7 is a tee pipe and includes an inlet and two outlets. The inlet is connected to the water supply pipe 9. The two outlets are symmetrically distributed left and right, and the two outlets are respectively connected to two adjacent hoses 6. The length of the hose 6 is long enough to be adjusted with the vertical rod 4 for use.
[0029] Specifically, as Figure 1 and Figure 2 shown, both ends of the cross bar 3 are provided with sliding grooves 10. Sliders 11 are slidably arranged in the sliding grooves 10 and locked by fasteners. The upper end of the vertical rod 4 extends upward and is connected to the slider 11. By horizontally sliding the slider 11 in the sliding groove 10, the vertical rod 4 can be driven to move accordingly, so as to adjust the distance between the two vertical rods 4 for spray maintenance of anti-collision walls with different widths, and the horizontal position of the anti-collision wall spray mechanism can also be adjusted to be applicable to roads with various widths.
[0030] Specifically, as Figure 1 and Figure 2 shown, a lift 15 is also installed on the base 1. The movable end of the lift 15 faces upward and is fixedly connected to the middle part of the bottom end of the cross bar 3. The lift 15 can be a cylinder, an electric cylinder or an oil cylinder in the prior art. By driving the cross bar 3 to rise and fall through the lift 15, the height of the cross bar 3 and the vertical rod 4 can be adjusted.
[0031] Specifically, as Figure 1 and Figure 2 shown, the device further includes a road surface spray pipe 12 arranged in front of the base 1. Both ends of the road surface spray pipe 12 are slidably sleeved with extension spray pipes 13. One end of the extension spray pipe 13 is slidably and sealingly connected to the road surface spray pipe 12 through a sliding seal 16. The other end of the extension spray pipe 13 is fixedly connected to the side part of the adjacent vertical rod 4. The middle part of the top end of the road surface spray pipe 12 has an inlet, and the inlet is connected to the water outlet end of the water pump 8 through a branch pipe 14. By pumping the clear water in the water tank 2 through the water pump 8, the clear water is injected into the road surface spray pipe 12 through the branch pipe 14. The clear water in the road surface spray pipe 12 is transmitted to the extension spray pipe 13, and the road surface and the anti-collision wall are sprayed simultaneously through the road surface spray pipe 12 and the extension spray pipe 13, and it is also applicable to roads with various widths;
[0032] It should be noted that the sliding seal 16 includes a seal seat and a seal ring. The seal seat is tubular and fixedly installed on the inner walls at both ends of the road surface spray pipe 12. The seal ring is installed inside the seal seat. The end of the extension spray pipe 13 passes through the seal ring and extends into the road surface spray pipe 12. When the extension spray pipe 13 expands and contracts with the movement of the vertical rod 4, it is sealed by the seal ring, so that the clear water in the road surface spray pipe 12 will not overflow from the joints at both ends. The sliding seal belongs to the existing mature technology, so the principle thereof will not be elaborated herein;
[0033] Furthermore, water spray nozzles are installed at the bottom of the road surface spray pipe 12 and are evenly distributed along its length. There is a gap for water supply circulation between the end of the water spray nozzle located inside the road surface spray pipe 12 and the sliding seal 16, so that the clear water in the road surface spray pipe 12 can be sprayed downward;
[0034] Furthermore, small holes are formed at the bottom of the extended spray pipe 13 and are evenly distributed along its length. Sprayers are installed in the small holes and are connected to the inside of the extended spray pipe 13. The sprayers are installed in a concealed manner to facilitate the horizontal pulling of the extended spray pipe 13.
