Description

Technical Field

[0001] The present application relates to the field of road and bridge maintenance, and more specifically, to a road and bridge pavement maintenance device. Background Art

[0002] Roads and bridges are generally composed of several parts, such as roadbed, pavement, bridge, tunnel engineering and traffic engineering facilities. Among them, the pavement is mainly divided into concrete pavement and asphalt pavement. Concrete pavement needs to be watered and maintained in the early stage of casting. The patent document with the prior art publication number CN217078338U provides a pavement maintenance device for road and bridge maintenance. The device extracts water from the water tank through a water pump, and sprays the pavement through the water outlet pipe, the connecting pipe and the adjustable nozzle in turn, and pulls the adjusting plate in the adjustable nozzle to slowly withdraw it from the adjusting groove, so that the adjusting cavity is connected to the connecting pipe through the adjusting groove, so that more nozzles on the sealing plate are supplied with water, the spraying area is expanded, and the spraying area is adjusted according to actual needs, so that the effect of spraying maintenance is better.

[0003] In view of the above-mentioned related technologies, the inventor believes that although the adjustment plate can change the number of nozzles for spraying water, the nozzles still spray water in a ring shape and cannot be adjusted according to the width of the road surface, resulting in multiple operations and low efficiency. Therefore, we propose a road bridge pavement maintenance device. Utility Model Content

[0011] By adopting the above technical solution, a sealing ring is arranged at the spray hole, and a through hole larger than the spray hole is opened on the sealing ring. Water can be discharged when the through hole coincides with the spray hole. When the sealing ring seals the spray hole, the water discharge is closed, so that the spacing of the water discharge can be adjusted according to the expanded width, thereby achieving water saving.

[0012] Optionally, a through hole is opened on the connecting rod B, a spring A is arranged in the through hole, and two ends of the spring A are respectively connected and fixed to the connecting rod B and the water tank.

[0013] By adopting the above technical solution, when the connecting rod B drives the movable tube to unfold, the spring A is stretched, and the resetting of the spring A is conducive to the reverse rotation and resetting of the movable tube, thereby improving the convenience of operation.

[0014] Optionally, the clamping block is slidably connected to the handle, and a spring B is connected between the two clamping blocks.

[0015] By adopting the above technical solution, the spring B drives the two clamping blocks to move away from each other, so that the clamping blocks abut against the limiting plate, thereby limiting the handle and keeping the movable tube at a fixed angle.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1. When the handle is lowered, the connecting rod B can drive the movable tube to rotate, so that the two movable tubes cooperate with the fixed tube to unfold in a trapezoidal shape, so that they can be adjusted and adapted according to the width of the road surface. The operation is simple, the number of operations is reduced, and the convenience of use is improved.

[0018] 2. The number and spacing of the spray holes of the movable pipe can be adjusted by rotating the sealing ring, so that it can be adjusted according to road conditions to save water. BRIEF DESCRIPTION OF THE DRAWINGS
