Motor insulation drying cabinet with double-suspension-door structure

Abstract

The invention belongs to the technical field of mining equipment, and in particular relates to a motor insulation drying cabinet with a double-suspension-door structure . The device is characterized by comprising a heating cabinet concave machine body, a chamfer suspended door and a convex suspended door, wherein the chamfer suspended door and the convex suspended door are respectively connected with the concave machine body of the heating cabinet through one-way thrust floating door shafts. The concave machine body of the heating cabinet comprises a box body, a concave ceiling arranged on theupper portion of the box body and a machine body base. The concave ceiling is provided with a trapezoidal groove. The convex suspended door is provided with a trapezoidal convex edge and a bevel edgeI. The chamfer suspended door is provided with a bevel edge II. The trapezoidal convex edge is in butt joint with the trapezoidal groove. The bevel edge I is in butt joint with the bevel edge II. Dueto the design of the double suspended doors, heating parts are easy to hoist, and internal parts of the heating cabinet are convenient to place. Compared with a traditional heating cabinet, the heating cabinet reduces the placing space. After heating is finished, the double suspended doors are opened, and an open platform can be formed on the heating cabinet base. Temperature diffusion in the cabinet after heating is facilitated, and the risk that maintainers work in a high-temperature environment is avoided.

Problems solved by technology

[0002] At present, more and more large-scale electromechanical components are used in mining equipment, such as electromechanical components on electric wheel vehicles, electric shovels and underground drilling rigs. The motors of these equipment work all the year round in high dust, high temperature and seasonal humid environments, resulting in motor insulation. The resistance value is reduced, which seriously affects the stable operation and service life of the equipment

When repairing large-scale electrical equipment, it is necessary to heat and dry the motor to restore its insulation strength, but it is difficult to find a matching heating cabinet. For example, an ordinary heating cabinet for an electric wheel-wheel motor assembly weighing 10 tons cannot accommodate its huge size and weight. , the wheel motor is usually decomposed and then heated and dried, which not only increases the workload and maintenance time, but also improper welding of the magnetic pole connection during assembly will cause damage to the insulating material, resulting in greater safety hazards

The large-scale motor insulation and drying equipment related to the domestic market generally adopts the method of laying guide rails, and uses the rail platform vehicle to push the drying equipment into the large heating cabinet. The heating and drying cabinet has the following disadvantages: 1. The heating motor is large and heavy, generally reaching 10 tons Above, it is laborious, time-consuming, and unsafe to push ordinary rail cars; 2. There is no hoisting equipment in the heating cabinet, and large spare parts need to be heated together with the platform car, causing problems of heat consumption and power consumption, and occupying space in the cabinet; 3. When heating After the end, the time to take out the spare parts is too long and the heat loss is too much, which cannot satisfy the assembly of the heating parts in the shortest time

4. The track laying of the heating cabinet needs to occupy a large space, and the initial investment cost is relatively large
