Bridge construction is generally divided into multiple stages, and each stage of construction will also generate a lot of waste, such as dust, stones, packaging bags, dropped fasteners or discarded steel bars, etc. If not cleaned up in time These wastes, such as steel bars, are easy to stab workers, packaging bags will cause environmental pollution, and falling fasteners will also cause losses if they are not recycled. Moreover, these wastes will also cause damage when carrying out concrete paving or asphalt paving, such as bridge decks. It hinders construction, so these wastes need to be cleaned up. Traditionally, manual cleaning is generally used, but because the area of the bridge deck is generally large, the workload of manual cleaning is large, and the cleaning effect of waste in some narrow gaps is not good.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a cleaning device for bridge construction that reduces the workload of manual cleaning.

In order to achieve the above purpose, the technical scheme of the present invention is: a cleaning device for bridge construction, including a vehicle frame and a cleaning mechanism, the bottom of the vehicle frame is provided with a traveling wheel, and the cleaning mechanism includes a rotating drive member fixed on the vehicle frame and a cleaning mechanism. A rotating shaft rotatably connected with the frame, the rotating shaft is arranged vertically, and the lower part of the rotating shaft is provided with a cleaning brush, the lower part of the frame is fixed with a connecting piece, the connecting piece is provided with a cleaning port, and the connecting piece is connected with a cleaning brush. collection bag.

The principle and beneficial effects of this scheme are as follows:

There are walking wheels at the bottom of the frame, when the worker pushes the frame, the frame can be moved relative to the ground under the action of the walking wheels, and the movement is more convenient. When working, the collection bag is located on the back side of the rotating shaft, which can ensure that the cleaning brush passes through the ground first, and when the rotating drive part drives the rotating shaft to rotate, the cleaning brush rotates to clean the waste on the ground. During cleaning, due to the rotation of the cleaning brush, the waste in contact with the cleaning brush rotates along with it, and then falls into the collection bag from the cleaning port under centrifugal action to be collected. Compared with bending over to clean the ground, it is more labor-saving for the worker to push the frame, which effectively reduces the workload of the worker.

Further, a water conduit is fixed on the frame, and the water conduit faces the cleaning brush.

The beneficial effects are: when the water conduit is connected with the external water pipe, water can flow to the cleaning brush along the water conduit to clean the cleaning brush and avoid a large number of stains remaining on the cleaning brush.

The negative pressure generator can keep the negative pressure in the negative pressure cavity and the connector. On the one hand, the negative pressure can suck up the dust on the ground and the wastes such as light packaging bags, so as to improve the cleaning effect; on the other hand, from the water conduit When the water flowing out of the middle cleans the cleaning brush, since the cleaning brush rotates with the rotating shaft, the water on the cleaning brush is separated from the cleaning brush under the centrifugal action, and small water droplets are formed in the inner cavity of the connector. When the pressure generator is working, the small water droplets in the inner cavity of the connector can be sucked up to avoid excessive water flow to the ground, and the dust will all adhere to the ground and cannot be cleaned, because if the dust adheres to the ground, When the water dries up, the dust will float again, and the cleaning effect is not good. Secondly, in this solution, the surface of the cleaning brush that is in contact with the ground is stained with water. When the cleaning brush is in contact with the ground, the floating dust will adhere to the cleaning brush, so it can reduce the floating dust and the residue on the ground.
