Portable Coal Mine Lighting Stand

Abstract

The invention discloses a portable lamp support rack used in coal mines and belongs to the technical field of coal mining devices. The object of the invention is to provide a portable lamp support rack used in coal mines, which is simple in structure, convenient to use, strong in practicability and easy to promote. The invention adopts the following technical scheme: the portable lamp support rackcomprises a base, wherein the right end of the base is hinged with a first sleeving rod; the upper part of the first sleeving rod sleeves a first telescopic rod; the upper end of the first telescopicrod is hinged with one end of a first folding rod; the other end of the first folding rod is hinged with one end of a second supporting rod; the other end of the second supporting rod is hinged withone end of a first supporting rod; the other end of the first supporting rod is fixedly connected with a lamp shade; a second-telescopic-rod clamping groove is formed in the middle part of the base; the bottom end of a second telescopic rod is clamped in the second-telescopic-rod clamping groove; a first chute is formed in the center of the lower part of a second folding rod and the second foldingrod is connected to the upper part of the second telescopic rod in a sleeving manner; the upper end of the second folding rod is hinged to the hinge joint (i.e. a pin rod) of the second supporting rod and the first folding rod; and an electric lamp is movably clamped in the lamp shade through an electric lamp chute.

Description

technical field [0001] The invention relates to a portable coal mine lighting bracket, which belongs to the technical field of coal mining equipment, and in particular relates to a mobile lighting bracket used in a coal mine. Background technique [0002] China began to use battery miner's lamps and electric lighting in a few mines in the 1930s. After 1949, battery miner's lamps and electric lighting were generally used. The basic requirements for mine lighting are: good lighting quality, high luminous efficiency, power saving, safety and reliability, Rugged and easy to install, use and service. China's coal mine safety regulations have specific regulations on the lighting requirements of the main locations of mines. Mine lighting fixtures are divided into fixed and mobile according to the way they are used, and mobile mine lighting needs to be supported by movable brackets. The existing lighting brackets Although the normal operation of the mine is guaranteed, and the supp...

China's coal mine safety regulations have specific regulations on the lighting requirements of the main locations of mines. Mine lighting fixtures are divided into fixed and mobile according to the way they are used, and mobile mine lighting needs to be supported by movable brackets. The existing lighting brackets Although it can ensure the normal operation of the mine, and the supporting power cord will not be entangled, it can ensure the smoothness of the mine road, but it cannot solve the problem of inconvenient carrying during the transportation of the coal mine support
