Description

Self-moving ultra-thin coal seam hydraulic support

Technical Field

The utility model belongs to the technical field of mine underground equipment, especially, relate to a from moving extremely thin coal seam hydraulic support.

Background

At present: in recent years, with the reduction of reserves of thick and medium-thick coal seams and the gradual depletion of resources, the exploitation of thin and ultra-thin coal seams has attracted high attention from the related departments of national safety production technology. Because key equipment and technology for mechanically mining the ultra-thin coal seam are lacked, the mode of single support and wood pillars is always adopted when the ultra-thin coal seam below 0.8m is mined for a long time in China, so that not only is the efficiency low, but also great potential safety hazards are caused, and the further improvement of the productivity is seriously hindered.

Through the above analysis, the problems and defects of the prior art are as follows: when an ultra-thin coal seam below 0.8m is mined, a single support and a wood pillar are always adopted, so that the efficiency is low, the potential safety hazard is great, and the further improvement of the productivity is seriously hindered.

The difficulty in solving the above problems and defects is: the mining of the extremely thin coal seam does not have proper supporting equipment and mining equipment, and the coal seam can only be manually supported by using a timber pile and dug by using a hoe, so that the potential safety hazard is great.

The significance of solving the problems and the defects is as follows: the utility model discloses an extremely thin coal seam is fully mechanized and is adopted and provides the advantage, has reduced intensity of labour, has improved the exploitation security.

SUMMERY OF THE UTILITY MODEL

To the problem that prior art exists, the utility model provides a from moving extremely thin coal seam hydraulic support.

The utility model discloses a realize like this, a from moving extremely thin coal seam hydraulic support is provided with: the two columns in the front row are fixed on the base, the single column in the rear row is fixed on the pushing beam, the front part of the pushing jack is hinged with the base, the rear part of the pushing jack is hinged with the pushing beam, and the pedal is installed on the base.

The pushing beam is arranged in the base in a drawer mode, a slide way is arranged in the base, the pushing beam is inserted into the slide way, and the relative movement of the pushing beam base can be realized through the stretching and the retracting of the pushing jack.

The column cap boot is fixed on the column head of the upright column, the column cap on the column cap boot is buckled on the column head of the upright column, and the column cap and the column head of the upright column are fixed together through the pin shaft, so that the effect of increasing the supporting area is achieved.

Combine foretell all technical scheme, the utility model discloses the advantage that possesses and positive effect are: the utility model provides a hydraulic support stability is good, simple structure, support capacity are strong, are applicable to 0.5m extremely thin coal seam, compare monomer strut in the past with the wooden pillar say, the utility model discloses alleviate workman intensity of labour, improved the automatic level of working face, increased the working face security, solved china when 0.5m height-mining, the blank that no hydraulic support strutted has very high using value and social, market prospect is extensive, convenient to popularize and apply.
