Description

The utility model can be used in industry, in agriculture, in construction, and in other industries to protect stationary devices from accidental impacts, in particular, to protect the belt drive of an engine mounted on a platform of a vibrorail from getting foreign objects into it.

Known protective casing of a monoblock type containing a bottom and a side wall, while the bottom is convex with trapezoidal stiffeners and has fixing eyes (see patent for utility model No. 46833, F16P 1/02, 2005).

The disadvantage of this device is the large metal consumption and the significant complexity of manufacturing.

Also known is a protective casing of a monoblock type containing a bottom and side walls enclosing a belt drive of an engine (see copyright certificate No. 1795199, F16H 7/02, 1990).

This device has the same disadvantages as the previous one.

The technical result of the claimed device is to reduce the cost of production while maintaining the quality indicators of protective

the functions of the casing as a whole by reducing the metal consumption and the complexity of manufacturing.

The specified technical result is achieved due to the fact that the protective casing, mainly for protecting the belt drive mounted on the platform of the engine, containing the bottom and side walls, is made of upper and lower parts with the possibility of attaching the upper part to the engine, and the lower part to the platform.

While the upper part of the casing is made with the possibility of covering its lower part.

The claimed utility model is illustrated by drawings, where

figure 1 shows the casing, a General view;

figure 2 - the upper part of the casing;

figure 3 - side wall of the upper part:

figure 4 - the lower part of the casing;

figure 5 is the same at the time of manufacture before bending;

figure 6 - casing in the working position, protecting the belt drive of the engine mounted on the platform of the vibrorails.

The protective casing 1 consists of two parts: the upper part 2 and the lower part 3, made of sheet metal. The upper part 2 of the casing 1 has a bottom 4 and a side wall 5, which provides protection from above and from the sides. The lower part 3 of the casing 1 has a bottom 6 and side walls 7 and 8, providing protection from below and from the sides. Wall 7 is made with

flanging 9. The parts 2 and 3 of the casing 1 facing each other do not have side walls (fences). The upper part 2 of the casing is made with the possibility of covering its lower part 3. On the wall 5 of the upper part 2 of the casing 1 holes 10 are made for fasteners, for example bolts (not shown in the drawings). On the lower part 3 of the casing 1, eyes 11 are made with holes 12 for fasteners. The thickness of the sheet of the upper part 2 of the casing 1 is less than the thickness of the sheet of the lower part 3 of the casing 1.

The device is manufactured and used as follows. The work is described by the example of protection of a belt drive of an engine mounted on a vibrorail platform.

The upper part 2 of the casing 1 is made of two parts: the bottom 4 and the wall 5, which are cut out of sheet metal, for example steel, and attached to each other by welding. Part 2 is attached to the engine 13 through holes 10, for example, with bolts.

Then cut out the lower part 3 of the casing 1, unbend the side and lower walls 7 and 8 and flanging 9. Place part 3 of the casing inside part 2. The lower wall 8 is inserted into the slot (not shown) of the platform 13 vibrorails, additionally fixed relative to the platform 14 by flanging 9, and through the holes 12 of the eyes 11 are attached to the motor housing 13 with bolts (not shown). The engine belt transmission is protected on all sides from foreign objects. After installing and securing the parts of the casing, the engine starts vibrorails.

The upper part 2 has larger dimensions than the lower one and is made of a thinner sheet, which allowed to reduce the metal consumption of the casing as a whole. The wall 5 and the bottom 4 of the part 2 of the casing 1 perform a protective function, preventing the ingress of foreign objects into the belt drive. The thickness of the metal sheet of the lower part 3 of the casing is optimally selected experimentally. Walls 7, 8 and bottom 6 serve as protection against foreign objects getting into the belt transmission zone, and wall 7 performs not only a protective function, but also is an element of fastening of part 3 to the platform 14 of the vibrorail. Parts of the casing are quickly and easily made by cutting, followed by welding (upper part) and bending (lower part), which reduces the complexity of manufacturing. Reducing metal consumption and labor intensity allows to reduce the cost of production while maintaining quality indicators.
