The single hydraulic prop is a new environmentally friendly support equipment. It can be used with metal hinged roof beams for high-end general mining and artillery working face support roofs and fully mechanized mining face support ends. It can be used as a separate point column or other temporary support.
Product introduction of single hydraulic prop
The single hydraulic prop is an externally supplied constant resistance single hydraulic prop. It can be matched with various roof beams and can also be used as the main column. It can be used to support the roof of the blasting mining working surface, and can also be used for other temporary supports.
The single hydraulic prop is suitable for inclined coal seam mining working faces where the coal seam inclination angle is less than 3 degrees. The conditions for the coal seam roof and floor that it adapts to are: the backwardness of the roof does not affect the recovery of the pillars, the bottom plate should not be too soft, and the depth of the pillars pressed into the bottom plate Do not deteriorate the integrity of the base plate, otherwise the base should be enlarged. When used in blasting mining working surfaces where coal is relatively soft, protective measures should be taken on the coating surface of the living cylinder to prevent collapse. When the pillars are matched with wooden roof beams or used as point columns, the top caps should be replaced with column caps to avoid damaging the wooden beams.
Product features of single hydraulic prop
Large working stroke and low safety management cost.
Each specification can replace one specification of the traditional piston-type single pillar, which reduces the frequency of changing different types of single pillars due to changes in the mining height of the working surface and the movement of the top and bottom plates in the tunnel, and reduces the labor costs of workers. Labor intensity and extra spare quantity of props.
, high support strength, good safety and stability.
The pillars have no load-bearing welds. At the same time, the pillars adopt the principle of suspension technology. The suspension force generated by the high-pressure liquid acts directly on the top end, reaching four-fifths of the working resistance. The force on the column is only one-fifth. The stability and eccentric load capacity of the pillar support are greatly improved.
Leakage is easy to detect, safe and reliable.
Due to structural improvements, the virtual roof and decapping of the pillar caused by internal leakage are avoided. Once the pillar leaks, it can be directly detected with the naked eye at the underground site. The pillar can be replaced at any time using seal compensation and seal expansion. According to the principle of tight technology, the greater the pressure from the top plate, the tighter the sealing surface fits and the less likely it is to leak.
, long service life, easy operation and maintenance.
The overall structure is simple, the service life is long, it is easy to operate and maintain, and it can greatly reduce the prop hoisting and maintenance rate.
Single hydraulic prop product classification
According to the different liquid supply methods and working fluids, props are divided into external liquid supply type (referred to as external injection type) and internal liquid supply type (referred to as internal injection type) props.
According to different working strokes, the pillars are divided into single telescopic (single stroke) pillars and double telescopic (double stroke) pillars. When the stroke characteristics are not specified, they are single telescopic pillars.
According to different materials used, pillars are divided into ordinary steel pillars, high titanium alloy pillars, aluminum alloy pillars, stainless steel pillars, etc. When the material characteristics are not specified, they are steel pillars.
According to the structural form, the pillars can be divided into two categories: piston pillars and plunger suspended pillars. Piston-type props are divided into single telescopic and double telescopic props according to their working stroke. The plunger suspended pillar uses water medium and is an environmentally friendly pillar.
