Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning apparatus for building materials which can efficiently remove dirt from temporary materials used for civil engineering construction work, for example.

[0002]

2. Description of the Related Art At present, there are many types of temporary materials used in civil engineering construction work, and it is said that maintenance and maintenance of such materials is one of the important factors for efficient and rational construction work. Have been done. Since such temporary materials are used on construction sites, they are apt to get dirty (especially paint), and most of the maintenance work after removal is
It is no exaggeration to say that the task of removing dirt is a major factor. So now, as a cleaning means,
A ring type, a brush type, a hit type, and the like can be given.

[0003]

However, in any case, the above-mentioned cleaning means basically only involves rubbing the surface with metal, and powdery residue remains on the work surface. In many cases, the work itself may be damaged. For this reason, after all, they have to rely on manual work and the use of chemicals, and especially for those with severe dirt, the work cost is too high. As a result, in addition to the operation efficiency of the materials, the space efficiency in utilizing the site was reduced. Further, the width of the temporary material to be cleaned is roughly divided into two types, and it has been required to efficiently process these with one cleaning device.
However, if the rotation radius of the rotary nozzle is set for a wide workpiece, high-pressure water will be wasted on a narrow workpiece, and conversely, a wide workpiece will be used on a narrow workpiece. In this case, the processing must be performed twice for each half width, which is not efficient. A method of arranging a large number of rotary nozzle devices having a small rotating diameter in parallel and using only a necessary portion in accordance with the work width can be considered, but this increases the initial cost by the number of the rotary nozzle devices.
In addition, because of the cost, it is not possible to increase the pump output unnecessarily.Therefore, assuming that a pump having a certain discharge water amount and all the rotary nozzle devices are used, the amount of water injected from one nozzle is reduced. I have to decide. In that case, the use of only a part of the rotary nozzle device means that only a part of the high-pressure water produced by the pump is used, which is still not efficient. The present invention has been proposed in order to improve the above problems, for example, a cleaning device for building materials that can efficiently remove dirt from temporary materials used for civil engineering construction work. The purpose is to provide.

[0004]

Here, the cleaning process in the cleaning device 2 will be described in more detail. When the work W to be cleaned is sent into the cleaning device 2 by the charging conveyor 7,
In the cleaning device 2, the work W is brought directly below the cleaning unit 21 by the conveyance guide roller 20 activated by the geared motor 16 which is a power source of the work W conveyance guide in the base 15. At this time, the separation distance (clearance) between the nozzle tips 60a to 60h and the surface of the work W at the tips of the nozzle arms 59a to 59h of the first rotary nozzle device 26 and the second rotary nozzle device 27 constituting the cleaning unit 21. ) Can be adjusted in advance according to the type of the workpiece W, the type and degree of dirt. That is, the lifting frame 2 on which the cleaning unit 21 is placed
5 is connected to a geared motor 29 on the upper part 28 of the outer frame 24.
Can be activated and adjusted upward and downward by the worm jack 30. Further, the cleaning unit 21 is attached to the outer frame 2.
With the winch 31 installed on the four sides, the lifting frame 25
By winding up a wire-W that is bridged and connected to one side of the base plate D of the elevating frame 25 via the pulley 32 arranged at the upper part, the base plate D of the elevating frame 25 is tilted and pulled up, and the first rotary nozzle device 26 And the nozzle arms 59a-59h and the nozzle tips 60a-60 of the second rotary nozzle device 27.

From the air through the control air supply tube Tu
By switching the supply to the toon-off valve 36, an on-off operation can be performed. When the first rotary nozzle device 26 or the second rotary nozzle device 27 is operated, the electromagnetic two-way valve 40 and the manual ball valve 41 in the cooling water supply passage Lwc are operated, and the ultrahigh pressure pump unit 33 is operated.

From 0a to 60h, it is sprayed on the surface of the work W. At this time, since the cylindrical rotating body 58 is rotating at a predetermined number of revolutions, the high-pressure cleaning water hits the surface of the work W in an arc. Here, the nozzle arms 59a to 59h are oriented such that the front end side is directed to the rotation axis side of the cylindrical rotary body 58 by approximately 60 degrees with respect to a horizontal portion, so that the high pressure is applied to the front and rear and both end surfaces of the work W. Wash water can be applied (see FIG. 7). In addition, since the tip ends of the nozzle arms 59a to 59h are inclined by approximately 30 degrees with respect to the vertical direction so that the tips of the nozzle arms 59a to 59h approach each other (see FIG. 8), the surface of the work W has irregularities. Also, since the jet flow hits the surface of the work W at a large angle (close to a right angle), a large separation effect of dirt can be expected (see FIG. 9).

As described above, the work W is peeled and cleaned while the work W is moved directly below the first rotary nozzle device 26 by the conveyance guide roller 20, and the cleaned work W is then moved into a sector shape in the adjacent low-pressure cleaning means 22. It is brought below the nozzles 44,44. Here, the solenoid valve 46 of the rinsing water supply path Lr is opened and the manual ball valve 47 is operated to
Rinsing water is sprayed from the fan-shaped nozzles 44, 44 onto the surface of the work W from which the dirt has been peeled off, so that cleaning can be performed. When the work W is further moved by the conveyance guide roller 20, this time, the work W is brought to the air-blowing means 23,
The drying air from the blower 50 is supplied to the drying air supply path Lad.
Through the blow nozzles 51, 51, the cleaned upper surface and lower surface of the work W can be dried. Then, it is taken out by the separation conveyor 8 and carried out by the unloading conveyor 9.
From the lifter 10 to the loading conveyor 11, the palletizer 12 loads a predetermined number of the washed works W on the pallet, unloads it by the unloading stock conveyor 13, stores it in a predetermined storage location, and stores it in new construction. They can be kept on standby for immediate service.

Effective cleaning is possible. (2) Since at least two rotary nozzle devices having different injection ranges are provided, it is possible to cope with various objects to be cleaned, and it is unnecessary to change the injection means according to the object to be cleaned. Also, consumables are reduced, and both initial cost and running cost can be kept low. (3) Since the injection means of the high-pressure water in the cleaning unit can be exposed from the cleaning chamber, maintenance and inspection work is facilitated. (4) Since at least two rotary nozzle devices having different injection ranges can be selectively switched and used, a rotary nozzle device that can efficiently use high-pressure water produced by a pump and that corresponds to the width of an object to be cleaned can be provided. Since it can act, an efficient peeling and cleaning effect can be expected. (5) By inclining the jetting direction, not only the surface of the object to be cleaned, but also the front, rear, left and right side surfaces, and the surroundings of the fitting can be uniformly peeled and cleaned. (6) By using high-pressure water, cleaning can be performed simultaneously with peeling, so that there is no residue. Further, unlike the means of simply rubbing the surface with metal, the object to be cleaned is not damaged, and the temporary construction material to be cleaned can be provided in a state similar to a new one for a long period of time.
