CS239560B1 - Protective cab for product finishes - Google Patents

Abstract

The invention relates to the field of surface treatment of products in production facilities of heavy and light industry. It solves the problem of protecting surrounding production areas during finishing work on various complicated or large-sized products, for example, during sandblasting and grinding cleaning, during welding, or during spray painting, while dangerous, dusty and gaseous exhalations are generated and noise is spread. The essence of the invention is a technical solution of a protective cabin for surface treatment of products, in which a sliding frame structure connected to a fixed frame can be expanded or contracted using a movement mechanism, while the elements of the sliding frames covered with an elastic coating are folded like an accordion. The invention can be advantageously used in all production facilities where the complexity of the shape and dimensions of metal or wooden products do not allow local removal of gaseous and dusty exhalations, or where it is necessary to reduce the noise of the production operation.

BACKGROUND OF THE INVENTION The present invention relates to a protective cabinet for surface treatment, which serves to protect the environment of production areas where they perform finishing work on various, complicated and bulky products. In particular, it covers the protection of production areas from dust and noise when cleaning the surface of the products by sandblasting and from volatile chemical eixhalates when painting products with paint or spraying.

So far, the protective booths used for the surface finish of products are usually stable, frame-like structures with rigid steel sheet walls, wooden booths, or other solid materials. The products are transported to such a fixed cab either from above by a sliding part of the roof by means of a crane, or through a door by means of a truck, or by other means of transport, respectively. of a lifting device. Such manipulation is lengthy, often and dangerous, while the dimensions of the products are considerably limited. A major disadvantage of such a solution is especially the high demands on the built-up area, which cannot be otherwise utilized, even though the protective cabin is not in the pre-operation for a long time. In particular, metal cabins do not comply with high noise levels.

The aforementioned drawbacks are eliminated by the protective coating of the products according to the invention, which consists in that it consists of a rigid frame connected to the sliding frames by means of a panto-graphical grating mounted on a fixed frame so that the frames can be moved on rollers by rails by means of an electric drive with a link chain and a tension roller, the lower part of the pan-graphical grating being guided freely in rollers by sliders in the sliding frames.

In addition, the rigid frame and the sliding frame are covered with an elastic accordion cover, with a removable structure on the floor of the cab, consisting of trusses, floor grates and elastic collecting trays, from which the suction hoses are sucked off by suction hoses. Exhaled gasses are also exhausted. The advantage of the protective cab for the surface treatment of the products according to the invention is the simplicity and low weight of the construction of an efficient dust collection, gaseous exhalation and sound insulation design. It is versatile and can be used in a 1 'large enough production area where the required load carrying capacity is available. The protective casing can be one-piece or two-part, whereby the sliding frames of the modular structure can be added as required.

When the sliding frames are completely displaced and the detachable grate is deposited, the protective cabin occupies a minimal part of the production surface, which can also be used for other purposes.

The retractable cab design also allows the surface treatment of large, rugged and heavy products.

1 shows a schematic diagram of a protective cabinet for the surface treatment of the articles of the invention in partial lateral view and partial cross-section, and FIG. 2 is a schematic diagram of a cross-sectional device.

The protective coating of the products according to the invention consists of a rigid frame 1 connected to the sliding frames 2 by means of a pantograph grille 3 mounted on the fixed pins 4 such that the sliding frames 2 can be moved on the rollers 5 by the rails 6 by means of an electric drive 7s. with a chain 8 and a tension roller 9, wherein the lower part of the pantograph 3 is loosely guided in the vertical direction by the sliders 10.

In addition, the rigid frame 1 and the sliding frames 2 are covered by an elastic accordion pull 11, with a detachable structure consisting of beams 12, floor gratings 13 and elastic collecting troughs 14, of which sand grit is extracted on the floor of the cab. by means of suction hoses 15, while gaseous exhalates are sucked through the hose 16.

Protective product coating cabin according to the enclosed drawing of a one-piece stable construction, with rails 6, electric drive 7, link chains 8 and tension rollers 9 installed in a covered floor channel.

The device can also be used in a one-piece arrangement, wherein the sliding frames 2 are moved against a fixed wall.

In the portable arrangement of the protective casing, the movement mechanisms are connected to the fixed frame 1 such that the entire one-piece device can be moved to another suitable space by means of a crane.

The maximum length of one part of the protective covering for the surface treatment of the articles can be varied as necessary by adjusting the removal of the individual links of the movable frames 2 and the pantograph 3 with an appropriate portion of the elastic coating 11 which is made of, for example, leather (artificial leather, rubberized). or a suitable other flexible, sufficiently rigid material. The 0-protection cab is an illuminated interior from the inside.

The invention can be advantageously applied in all production plants of the heavy and light engineering industry, wherever the products are surface treated (eg, sandblasted, spray-painted, grinding, etc.) directly in the manufacturing areas, it is necessary to protect the surroundings by pre-washing, volatile chemical vapors of noise.

The device can also be used for other
