Unfreezing device for a railway coal conveying carriage

Abstract

The invention provides an unfreezing device for a railway coal conveying carriage, which can unfreeze frozen coal bodies in the railway transportation carriage, makes the railway transportation carriage capable of unloading coal at the same speed in winter and summer. The unfreezing device consists of a fixed frame mechanism and a bridge vehicle mechanism, wherein the fixed frame mechanism is connected with the bridge vehicle mechanism; the fixed frame mechanism comprises a beam, a left strut, a right strut, a lifting hoist, a wire rope, a vertical moving unit, a horizontal moving unit, a carriage outside electromagnetic hammer, a carriage bottom electromagnetic hammer and a high-frequency eddy current coil; the vertical moving unit is connected with the horizontal moving unit; the left strut and the right strut are connected with the carriage outside electromagnetic hammer, the carriage bottom electromagnetic hammer and the high-frequency eddy current coil respectively; the bridge vehicle mechanism comprises a heating unit and a crushing mechanism; and the crushing mechanism is connected with the heating unit. The unfreezing device for the railway coal conveying carriage can complete a coal unloading task within 6 min, improves the railway coal conveying to-and-fro efficiency in cold areas in winter, and reduces enterprise cost for power generation and ports.

Description

(1) Technical field [0001] The invention relates to coal transportation technology, in particular to a defreezing device for railway coal transportation carriages. (2) Background technology [0002] In the cold season of winter, when the railway transports coal to the cold area, the coal and the carriages are often frozen together. The reason is that the coal mine coal is directly loaded into the carriages, the coal contains a lot of water, and the water seeps out from the coal body and freezes, causing serious damage to the coal unloading work. Difficulties, especially in Northwest China, Northeast China, Inner Mongolia, and some North China power plants and ports, the problem of loading and unloading lignite in winter is more serious, resulting in difficulties in the work of equipment such as railway carriage dumpers, manual operation is labor-intensive, and coal unloading takes a long time. high cost. In response to this problem, enterprises such as railways, power plant...

Problems solved by technology

[0002] In the cold season of winter, when the railway transports coal to the cold area, the coal and the carriages are often frozen together. The reason is that the coal mine coal is directly loaded into the carriages, the coal contains a lot of water, and the water seeps out from the coal body and freezes, causing serious damage to the coal unloading work. Difficulties, especially in Northwest China, Northeast China, Inner Mongolia, and some North China power plants and ports, the problem of loading and unloading lignite in winter is more serious, resulting in difficulties in the work of equipment such as railway carriage dumpers, manual operation is labor-intensive, and coal unloading takes a long time. high cost

In response to this problem, enterprises such as railways, power plants, ports, etc. currently do not have special and effective railway transport carriage thawing equipment or facilities that can complete the task of unloading coal in a carriage within 6 minutes.
