Description

i

The invention relates to electrical engineering, namely, cabinets designed to house electrical equipment for automatic control systems.

Cabinets for accommodating electrical equipment are known, comprising a welded body mounted on the base and doors with locking devices. The body consists of the rear, side walls and the upper and lower clamps, welded into a one-piece construction tl.

The disadvantage of this design is the laboriousness of manufacture and the fact that the walls of the cabinet are not removable.

Cabinets for the placement of electrical equipment are known, consisting of a welded body mounted on the base, removable side and rear walls and doors with locking devices. The corpus includes four corner posts, top and bottom covers, which are welded into a one-piece construction. Racks, top and bottom covers are made of bent sheet material. Removable walls are bolted to the threaded plates welded to the housing.

The disadvantages of this design are that the corner vertical posts of the case have a complicated configuration and are laborious in manufacturing the upper and lower covers of the cabinet are part of the case, which increases its dimensions and complicates the assembly; lack of detachable elements makes unification difficult

IS constructions; Removable sleeves are fastened to the housing with the help of threaded connections of a complex construction, which does not exclude access to the closed cabinet.

The purpose of the invention is to reduce the labor intensity of manufacturing, simplify assembly, reduce overall dimensions and unify the main components. The goal is achieved by the fact that in a prefabricated welded cabinet consisting of a housing containing four angular vertical posts and longitudinal beams, removable walls and doors, angular vertical posts and longitudinal beams are made of a U-shaped profile with rigid beams attached to them. K-shaped profile, forming Topi internal inner recessed sides, which are fastened with bolted joints of the S1 removable walls and the upper lid, and the bolts are welded to (removable walls and to the upper lid. Lia drawing shows a cabinet, general view, the door is conventionally not shown. The cabinet includes a body 1, a base 2, side walls 3 rear wall C, upper cover 5 corner posts 6 and longitudinal beams 7 of the U-shaped profile, to which corner beams are rigidly attached (for example, welded) and a profile-shaped profile 9 forming inner recessed sides, to which removable walls 3 and C and upper cover 5 are fixed by bolts 10, and bolts 10 are welded to removable walls 3 and t and a cover. The proposed assembly of an assembled cabinet is characterized in that its casing is made of bent standard profiles, which significantly reduces the metal consumption of the cabinet and the complexity of its manufacture. The removable walls and the cover are fastened to the body with the help of nuts and bolts welded to the corresponding assemblies, which considerably simplifies the assembly and is convenient in operation. Removable walls are attached to the end inner beads; and do not stand for the dimensions of the case, which reduces the overall dimensions of the cabinet and allows using 4 simple fastening elements to join the cabinets on the lateral or rear sides of the cabinet and to receive cabinets of modular construction with new overall dimensions and total internal volume at the same time docking cabinets. In addition, the cabinet consists of detachable elements that allow to unify its design. The use of cabinets of prefabricated welded structures using standard bent profiles will give an estimated economic effect of at least 700 thousand rubles a year. Claims of the Cabinet for placing electrical equipment consisting of a housing containing angular vertical posts connected by horizontal beams and removable walls and doors, characterized in that, in order to reduce the labor intensity of manufacturing, simplify assembly, reduce overall dimensions and unify, angular vertical stands and horizontal beams are made of a U-shaped profile with rigidly attached to them beams of a corner and X-shaped profile, forming end ribs, to which bolted joints are removable and the upper wall of the lid, wherein the bolts are rigidly attached to the removable wall and the top cover.
