Description

Technical Field

[0001] The utility model relates to the technical field of mining monorail hanging beams, in particular to a central beam for lifting heavy objects on a mining cable monorail. Background Art

[0002] At present, the existing technology in coal mines has relatively heavy frequency converters, transformers, cable reels, emulsion pumps, etc., especially the frequency converters, transformers, cable reels, emulsion pump stations and other heavy equipment from the rear end of the mobile substation of the comprehensive mining face to the mining face. These heavy equipment are difficult to move, which affects the progress of construction. The traditional way of moving is to lift the equipment by manpower and drag it forward by manpower, which greatly affects the progress of work and consumes a lot of labor. Alternatively, a monorail lifting beam is used for dragging. However, when using a monorail lifting beam for dragging, the cables on the equipment need to be removed before lifting and transporting, which greatly wastes working time and reduces work efficiency. Moreover, the existing monorail lifting beam is not a dedicated lifting device for underground frequency converters, transformers, cable reels, and emulsion pump stations. The ground of the excavation tunnel is uneven, and the placement of the transformer requires a flat ground, which consumes a lot of labor. Without the use of a special lifting device, installation and disassembly are very troublesome. Utility Model Content

[0020] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0021] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0023] like Figures 1 to 5 As shown, a central beam of a mining cable monorail for lifting heavy objects includes a track 1, on which a load-bearing trolley 2 that can slide on the track 1 is provided.
