Track crane for underground coal mines

Abstract

The invention discloses a track crane for underground coal mines. The track crane comprises a flat lorry, travelling wheels and track clamping instruments are mounted at the bottom of the flat lorry, the lower parts of the track clamping instruments are in connection with the track, the flat lorry is equipped with a crane jib device, a reel, a crane jib support mechanism and a reel driving mechanism, the crane jib device consists of a support frame, a bracket, a telescopic arm and a jack. The lower end of the bracket is fixedly connected to the top of the support frame, the bracket inner wall is provided with a clamping slot, the lower end of the telescopic arm stretches into the bracket and can slide along the clamping slot, one end of the jack is connected to the support frame, and the other end of the jack is connected to the lower end of the telescopic arm, a first directional wheel is mounted at the upper end of the telescopic arm, the support frame is mounted on the flat lorry, a hoisting rope is winded on the reel, the end of the hoisting rope bypasses the first directional wheel and is then connected to a hook. The invention effectively improves the current downhole operation conditions, enhances the efficiency of moving heavy equipment in an inclined lane or gate way or installing heavy cables or other pipelines at the laneway top, reduces the cost, and eliminates potential safety hazards.

Description

technical field [0001] The invention relates to a crane truck used in underground coal mines, in particular to a rail crane truck used in underground coal mines. Background technique [0002] In coal mine shafts, the working space is limited and the working environment is complicated. In addition to installing necessary ventilation systems and power systems, a large number of mechanical equipment must be placed in the shafts, and belts or tracks for transporting coal or materials need to be reserved; most Underground high-voltage cables, mechanical equipment, and pipelines not only take up a lot of space, but are also relatively heavy. In order to save space in the shaft, many cables and pipelines need to be installed on the top of the shaft to facilitate the passage of miners or other mechanical equipment. Heavy cables and pipelines generally have to be lifted to a height of 3m to 4m. At present, mine geological structures in most areas of China are complex, and there are ...
