Description

Technical Field

[0001] The invention relates to the technical field of highway maintenance equipment, in particular to a water sprinkling maintenance device for highway maintenance. Background Art

[0002] As an important infrastructure of current transportation, expressways need to be regularly maintained in order to extend their service life.

[0003] Sprinkler maintenance is one of the links in highway maintenance. In hot weather or dry seasons, the road surface of the highway is prone to dehydration and drying, which leads to cracks in the road surface. In order to maintain the humidity of the road surface and reduce the temperature of the road surface, a sprinkler truck is needed to carry out watering maintenance. The water sprinkled on the highway can not only reduce the temperature but also clean up the dust and debris on the road surface.

[0004] As for the existing watering maintenance, since the road conditions in different sections are different, after the road surface is eroded by rain, oil or chemicals, in order to improve the strength of the road surface, ordinary clean water cannot meet the maintenance effect. At this time, it is necessary to manually configure the required maintenance liquid and add it to the water storage tank for maintenance. In addition, when there are natural water sources such as lakes and rivers near the highway, pumping equipment is usually used to pump the water in them into the water storage tank for use. The water in these water sources has solid impurities, and the configured maintenance liquid will produce flocs and solid impurities due to chemical reactions. These impurities easily clog the nozzles, resulting in a decrease in maintenance efficiency. Third, during the maintenance process, the water source in the water storage tank is pumped by a high-pressure water pump. In order to shorten the time required for maintenance, it is necessary to increase the power of the high-pressure water pump, which imposes a considerable burden on the high-pressure water pump. For this reason, a watering maintenance device for highway maintenance is proposed to solve the above problems. Summary of the invention

[0016] Preferably, a start button is provided at the top end of the rotating shaft, and the start button is electrically connected to the electric telescopic rod.

[0017] Working principle: After pressing the start button, the electric telescopic rod contracts, causing the cable reel to drop. While the cable reel drops, the blocking pin slides out of the pin hole on the mounting ring, is retracted into the rotating shaft, and squeezes the spring. At this time, the turntable is rotated to make the take-up shaft and the rotating shaft rotate at the same time, and the first pull rope is reeled in, causing the baffle to rotate around the steering shaft. Then the electric telescopic rod is powered off and reset, and the spring pops out the blocking pin, which is inserted into the pin hole, preventing the rotating shaft from rotating. After opening the water inlet, add the required curing agent to the space formed by the partition, baffle and water tank, and add water to the other space. When the water is When it is time to use the curing liquid configured with the curing agent, press the start button again, the baffle rotates under the action of gravity, and since the baffle is placed at an angle, the curing agent is poured into the water, and then the stirring motor is started. Under the meshing relationship between the driving gear and the driven gear, the rotating column and the stirring blade are rotated, and the configured curing liquid is extracted by a high-pressure water pump and transmitted to the circulation box by the water inlet pipe. The water flowing into the grid box passes through the primary filter, the intermediate filter, and the high-efficiency filter. Impurities are retained by the filter, and the filtered curing liquid enters the connecting pipe and then disperses to the installation pipe, and is sprayed out by the rotating nozzle.

[0018] The present invention provides a water sprinkling maintenance device for highway maintenance, which has the following beneficial effects:

[0019] 1. The present invention divides the water storage tank into two parts by a baffle and a partition, and then adds clean water to the larger space and the reagent to the other space. When facing the ground that needs special maintenance, the baffle is lowered by the retracting mechanism, and then the stirring mechanism can stir the reagent and water, thereby avoiding manual replacement of the maintenance medium, improving the flexibility of the equipment, and improving the efficiency of maintenance.

[0020] 2. The present invention uses a high-pressure water pump and a water outlet pipe in the spraying mechanism to allow the water source in the water storage tank or the newly configured curing liquid to flow into the circulation box, and then filter through the filter net in the grid box. Solid impurities and the like are retained in the circulation box, so that the rotating nozzle will not be easily blocked, thereby extending the service life of the equipment and ensuring the maintenance efficiency of the equipment.

[0021] 3. The present invention uses the stirring blades in the stirring mechanism to stir the medium in the water storage tank. At this time, the medium has a certain flow rate, and the stirring blades can also push the medium to the high-pressure water pump, which reduces the workload of the high-pressure water pump, extends the service life of the high-pressure water pump, and shortens the time required for maintenance.
