Telescopic girder of stacking automatic covering machine

Abstract

The invention relates to covering machine equipment, in particular to a telescopic girder of a stacking automatic covering machine. The stacking automatic covering machine comprises a stand column, fixed beams, telescopic beams and a walking trolley, wherein a traction device and the fixed beams are sequentially arranged on the stand column from top to bottom, the walking trolley is arranged at the bottom of the stand column, counterweight iron is arranged at one ends of the fixed beams, the telescopic beams are arranged at the other ends of the fixed beams, and a driving device is arranged onthe telescopic beams; the telescopic girder is structurally improved on the basis of a traditional lever girder, and the requirement for the length of the girder is met by adopting a mode of end-to-end sleeving and extending. According to the telescopic girder of the stacking automatic covering machine, the traction device which is in matched connection with the telescopic girder through a steelwire rope is arranged at the top of the stand column, the driving device which is in matched connection with the telescopic girder through a motor is arranged in the middle of the stand column, electronic control of the telescopic girder in the stretching process can be realized by arranging the traction device and the driving device, the stability and the use strength of the telescopic girder inthe stretching process are increased, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a towing machine equipment, in particular to a retractable girder of a stacking automatic towing machine. Background technique [0002] As my country's requirements for environmental quality are getting higher and higher, bulk materials (such as coal, ore, etc.) stacked in the open air at docks, stations, and freight yards must be treated in an environmentally friendly manner. At present, the most adopted environmental protection measures are to cover bulk material piles . However, the thatch covering of bulk material piles is almost all carried out manually, and its disadvantages are: labor intensity is high, work efficiency is low, and the working environment is harsh. [0003] Since the existing stacking width is generally about 40 meters, in actual work it is required that the beam of the automatic stacking and covering machine should be about 50 meters. difficulty.
