Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an asbestos removal machine used for removing and recovering asbestos sprayed onto a ceiling.

[Prior Art] Asbestos was already found to be a carcinogenic substance in the late 1960s. Although its use is now prohibited in principle, asbestos has been commonly used as a spray material for ceilings for many years even after it was discovered that it is carcinogenic, so there are still many buildings that use asbestos. .

Recently, the removal of asbestos has finally started to attract attention, and the removal of zero asbestos is done manually.
The manual removal procedure is as shown below.

(+) Cover the entire inside of the llj with a vinyl sheet to protect it.

The areas covered are floors, walls, pipes, and ducts.

(2) Scaffold 0, where the work scaffold will be assembled, will be covered with vinyl sheets in the same way.

(3) Start of work A dust collector is installed in the tiO, and dust continues to be collected throughout the entire work area during work. All workers wear dust-proof clothing and masks. Manual methods for asbestos removal include spatulas, etc. Scrape off the asbestos adhering to the deck plate, then scrape it off with a wire brush to make sure there is no residue left, and repeat this process to proceed with the asbestos removal process. The removed asbestos will fall to the floor, so sweep it up with a broom, etc., and pack it in a plastic bag for disposal. When cleaning the floor, wipe off asbestos dust with a mop.

In addition, when leaving the work area, put on and take off dust-proof clothing and dust-proof masks in the entry/exit preparation room.

(4) Remove and dispose of the vinyl sheet for curing. The scaffolding will then be dismantled.

[Problem WU to be Solved by the Invention] However, the conventional manual asbestos removal process described above is inefficient due to manual labor. In addition, since the workers wear airtight dust-proof clothing, they sweat, which makes the work hard work.

In addition, the asbestos removal effect is incomplete due to manual labor. Furthermore, as asbestos dust is suspended in the indoor environment during removal work,
The problem is that the environment is getting worse.

Furthermore, since asbestos removal is inefficient and incomplete as it relies on manual labor, there is a problem in that the construction work is prolonged and costs are incurred. Furthermore, since the working environment is not safe, the workers involved in the work must take precautions against dust, such as wearing protective clothing and masks, which further reduces work efficiency.

Therefore, the present invention was made with attention to the above-mentioned problems, and its purpose is to efficiently, completely and quickly remove asbestos sprayed onto the groove-shaped deck plate of the ceiling by mechanizing asbestos removal. Moreover, it is an object of the present invention to provide an asbestos removal machine that can improve safety.

[Means for Solving the Problems] An asbestos removal machine of the present invention that achieves the above object includes an asbestos removal device that removes asbestos blown onto the ceiling, and a traveling trolley that supports the asbestos removal device in a freely movable manner. and a recovery device for recovering asbestos removed by the asbestos removal device.

The asbestos removal device has a head portion equipped with a rotary cutter in which a hard brush is embedded in a rotary body with an uneven shape corresponding to the cross-sectional shape of the asbestos sprayed on the ceiling deck plate, and this head portion is moved in the vertical direction. A lift actuator that rotates the head, a turn actuator that rotates the head, and a slide actuator that slides the head in a direction perpendicular to the groove of the deck plate.

Further, according to a preferred embodiment of the present invention, (1) the slide actuator includes a stand that is vertically movably supported by the traveling truck, a slide table that is slidably supported by the stand, and one of the slide table and the stand. a rack gear provided on the slide table and the stand, and a pinion gear and a pinion gear drive motor provided on the other of the slide table and the stand;
■The lift actuator is equipped with a lift table that is installed on a slide table so that it can move up and down via an arm, and a hydraulic cylinder that biases the arm to rotate.
■The turn actuator consists of a turntable rotatably supported by a lift table, an arc-shaped rack gear provided on one of the turntable and the lift table, and a pinion gear and a pinion gear provided on the other of the turntable and the lift table. ■The head part has a double structure consisting of a dustproof hood supported by the turntable and an inner foot surrounded by the dustproof hood, and a rotary cutter is attached to this inner foot. It is characterized by being rotatably stored.

[Operations] For example, when removing asbestos that has been sprayed onto a groove-shaped deck plate on the ceiling, the asbestos removal device is first positioned by the travel of the traveling trolley, and then the asbestos removal device is moved by the slide actuator, lift actuator, and turn actuator of the asbestos removal device. The rotating brush of the head part is set in the groove of the deck plate.Then, with the head part swinging freely, the rotating brush is rotated at high speed and moved along the groove of the deck plate by the running of the traveling cart. As a result, the asbestos sprayed onto the groove-shaped deck plate is removed, passes through the inner hood, and is stored in a plastic bag inside the drum.1 Asbestos dust passes through the dust-proof hood and is collected in the dust collecting section of the collection device. Ru.
