Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning device suitable for cleaning cable trays, ducts, etc.

[Prior art and its problems]

Traditionally, when cleaning long, hard-to-reach items such as cable trays and ducts, workers have to move on scaffolding to remove debris by sweeping it with a brush, or use air. I was blowing it away. However, this conventional cleaning method has poor work efficiency, and not only does the main cleaning work not proceed smoothly, but it also sometimes becomes difficult to perform the work in a narrow space.

[Purpose and structure of the invention]

In view of these points, the present invention was developed with the purpose of providing a cleaning device such as a cable tray that can improve work efficiency and can also perform cleaning work in narrow spaces. The structure is as follows.

That is, a cleaning brush 12 and a cleaning nozzle 15 are installed on the front surface of a cart 1 which is equipped with a side guide device 5 whose side is guided by a side wall of a cable tray or the like, and which has wheels 4 on the lower surface. This is a cleaning device equipped with a traction member 13 for pulling the .

[Example of idea]

Next, embodiments of the present invention will be described based on the drawings. FIG. 1 is a plan view of an embodiment of the present invention, FIG. 3 is a side view thereof, and FIG. 2 is a sectional view of a cable tray that is an example of the object to be cleaned. In the figure, a trolley 1 includes a lower body 2 and an upper body 3 divided into left and right parts. Wheels 4 are attached to the lower surface of the lower body 2. Furthermore, a side guide device is provided on the side surface of the upper body 3. In this embodiment, the wheels 6 are movably elastically brought into contact with the side surfaces of the upper body 3 via springs 7. Note that 8 is a washer, and 9 is a bolt that also serves as a stopper and support. 10 is a fixing tightening screw, 11 is an adjustment slit provided in the upper body 3, and these are used to tighten and fix the upper body 3, which is divided into left and right parts, so as to be movable and adjustable relative to the lower body 2. . Also, a cleaning brush 1 is installed on the front of the trolley 1.
2 is provided, and a traction member 13 made of a chain, string, or the like for towing the trolley 1 is also provided. Next, a connecting fitting for the traction member 13 is provided on the rear surface of the truck 1. Further, a cleaning nozzle 15 is installed on the front surface of the truck 1, and is fitted into the cleaning nozzle 15 from the left and right sides, so that it can be adjusted in and out. This cleaning nozzle 15 is connected to the pipe 1.
6 to the hose 17, and further communicates with an appropriately selected discharge pump or suction pump (not shown). Note that the tip cover 1 adjusts the air volume from the center of the cleaning nozzle 15.
8 is provided. Note that 19 indicates a cable tray.

To use the embodiment having the above structure, first, both ends of the cleaning nozzle 15 are connected to the cable tray 19.
Adjust the amount of fitting so that there is a slight gap between it and the inner surface of the side wall, and then tighten the fixing screw 10.
The positions of the upper bodies 3, 3 are adjusted and fixed by the adjustment slits 11 so that the wheels 6 of the side guide device 5 come into elastic contact with the inner surface of the side wall of the cable tray 19 or the upper edge of the side wall. Then, when a pump (not shown) is operated, the cleaning nozzle 15 starts discharging or suctioning air depending on the selected type of pump. In addition, when selecting the former discharge method, it is convenient to separately install a suction nozzle in the center of the cleaning brush where dust collects, since the dust can be sucked without scattering. The cleaning device 1 that has started its operation in this way is operated by the traction member 13
It can be moved within the cable tray 19 by pulling. Therefore, the dust in the cable tray 19 is moved forward by the air discharged from the cleaning nozzle 15 and collected forward by the cleaning brush 12, or is sucked into the cleaning nozzle 15. be excluded by being In this case, it is more difficult to remove dust from the corners, so whether you choose the discharge method or the suction method, the air volume of the cleaning nozzle 15 should be larger at both ends than at the center. It is a good idea to set this. Furthermore, if the traction member 13 is also connected to the connecting fitting 14 provided on the rear surface of the trolley 1, the cleaning device can be repeatedly moved back and forth, and cleaning can be repeated easily. This means that it can be cleaned thoroughly.

Note that FIG. 4 shows another embodiment of the cleaning brush 12, in which the width of the cable tray 19 is adjusted by sliding in the horizontal direction in A and by rotating in B and C. This can be adjusted accordingly.

[Effect of idea]

Since the present invention has the above-described configuration, the following effects can be obtained.

(1) Even when cleaning long objects such as cable trays and ducts, the cleaning device can be moved while cleaning by simply pulling the traction member.
The efficiency of the cleaning work can be improved and smooth cleaning work can be realized.

(2) Even in narrow spaces where manual cleaning is virtually difficult, cleaning can be done simply by passing a traction member through the cable tray or duct, allowing for more complete cleaning. becomes possible.
