Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for sprinkling water to suppress the generation of dust at a construction demolition work site.

[0002]

[Prior art]

 At the demolition work site, in addition to the dust generated by the destruction of the building by the crushing equipment, the dust generated due to the collapse and fall of the dismantlement, etc. will generate a large amount of dust. This is usually done by connecting a hose to the water faucet or by using an existing water storage tank to store tap water and sprinkling it with a small water spray pump.

[0003]

[Problems to be solved by the device]

 In general, the amount of dust generated is often unexpectedly large at the site of dismantling work, while the amount of water sprinkled and the distance reached are insufficient, and dust is the core of the danger due to the danger of collapse of the dismantled material. There is a problem that it often does not approach the center of occurrence.

[0004]

[Means for Solving the Problems]

 By the way, in recent years, it has become common to operate vehicles that move in dangerous areas wirelessly.For example, a large hole for hoppers that is provided on the mountain using a transport machine such as a bulldozer to collect a large amount of limestone mined by open-pit mining. It is used when pushing it down. With this method, it was possible to push the work to the edge of the hole because there was concern about the bulldozer falling, but it is possible to operate the vehicle several times by one person. On the other hand, the present invention makes it possible to move a large water tank and sprinkling nozzle on a trolley so that the crawler can move even in a place where scattered debris is scattered. The above problem was solved by constructing it so that sufficient water can be sprinkled toward it. That is, according to the present invention, the above-mentioned problem is to provide a water tank, an injection pump, and a lifting stand on a self-propelled carriage having a crawler, and additionally install a nozzle on the lifting stand via a nozzle support. , This nozzle can be horizontally rotated and vertically tilted by radio wirelessly via a deceleration motor provided in the nozzle receiving and supporting unit by a sprinkler for dismantling work. Will be resolved. The sprinkler of the present invention will be described in more detail with reference to the following examples.

[0005]

【Example】

 An embodiment of the sprinkler of the present invention will be described below with reference to the drawings. As shown in FIG. 1, as a whole, as shown in FIG. 1, a water tank 2 of 500 liters made of polyethylene is installed above a self-propelled carriage having a crawler 1, and a nozzle 4 that can change the injection direction by remote control is installed on an elevation stand 3. The injection pump 5 is composed of a three-stage turbine pump that can use a 100-volt power source. Further, in the figure, 6 is a hose connecting the nozzle 4 and the injection pump 5, 7 is a water supply port of the water storage tank 2, and has an opening / closing cock which is operated by a float. Reference numeral 8 represents an operation radio wave receiving antenna, 9 a nozzle operation panel with a wireless receiver, 10 a handle for moving up and down the lifting stand 3, and 11 a crawler operation panel. A drive engine, an engine generator, and the like are provided inside the crawler 1. Next, FIGS. 2A and 2B are views showing the details of the nozzle receiving and supporting portion 12 provided on the top of the elevating stand 3. In this nozzle receiving / supporting portion 12, a tilting base 15 is attached to the upper parts of the left and right frames 13 made of pipes via a horizontal shaft 14, and further a pivoting motion provided on the tilting base 15 via a vertical shaft 16. A nozzle 4 is attached to the table 17. The rotary table 17 is a vertical motor. It can be rotated horizontally by the deceleration motor 18 and can change its direction by 180 ° in the left-right direction, and can also be rotated 90 degrees to the front through the connecting rod 20 by the deceleration motor 19 which is a horizontal motor. ° Can be tilted. This rotation is directly operated via the nozzle operation panel 9 or is performed by wireless remote operation. In addition, although the raising / lowering of the raising / lowering stand 3 is manually operated by the handle 10 in the illustrated embodiment, it may be raised / lowered wirelessly.

[0006]

[Action and effect]

 The sprinkler for dismantling work according to the present invention is configured as described above, and can be moved even in a poor terrain through the crawler 1, and after approaching the required dismantling site, the operator can move backward from the trolley. It is possible to wirelessly operate the nozzle of the trolley via the handheld operation panel at the position and drive the speed reduction motors 18 and 19 via the amplifier loaded in the trolley to perform sufficient water injection in the required direction. . If necessary, the nozzle receiving / supporting portion 12 may be removed from the elevating stand 3 and attached to another place. As described above, the device of the present invention can safely approach the object to be disassembled even in a dangerous place, can reliably set a target and spray water, and can operate several units at the same time. In this embodiment, for example, 7 systems can be operated, and 7 units can be operated simultaneously. In addition, since the water tank 2 is mounted, a large amount of water can be freely sprinkled, and the water tank 2 can be easily replenished from a water faucet at an appropriate time, and an automatic opening / closing valve by a float is provided. Since it is equipped, no manpower for water supply is required. Further, since the water spraying injection pump 5 is for 100 volt, it has many advantages such that it can be easily operated from a normal household power source through the capty cord.
