Abstract

The invention discloses a nickel-titanium alloy web membrane technology of a single hydraulic prop for a mine, and belongs to the technical field of mine mechanisms. The nickel-titanium alloy web membrane technology mainly comprises a piston guide sleeve, a piston, a limiting steel wire, an oil cylinder subassembly, a handle body, a plunger guide sleeve, a liquid injecting valve body, a plunger body, a close cover, a top cover and a three-functional valve, wherein the piston and the plunger body are arranged in the oil cylinder subassembly, and the piston is arranged at the lower part of the plunger body; the oil cylinder subassembly and the plunger body are assembled and fixed through the handle body and a casting; a valve seat is welded on the plunger body, and internally provided with the three-functional valve; a sleeve is fixed outside the plunger body between the handle body and the top cover; and the matching clearances among the matching surface of the plunger body and the close cover, the matching surface of the plunger body and the handle body, and the matching surface of the oil cylinder subassembly and a pedestal are controlled to 0.08-0.12mm. The nickel-titanium alloy web membrane technology disclosed by the invention is high in corrosion resistant and wearable performances, can be widely applied, and is especially suitable for being applied to an area with high sulfur; and the nickel-titanium alloy web membrane technology improves the mechanical intensity, is good in sealing performance, and long in service life.

Description

technical field [0001] The invention relates to a nickel-titanium alloy peritoneal technology, which is an improvement on the prior art, and in particular relates to a nickel-titanium alloy peritoneal technology for mining single hydraulic props. Background technique [0002] The pillar of the underground mining face is one of the essential equipment in the mine. The support equipment used in mines in my country has various structural forms such as wooden pillars, single metal friction pillars, single hydraulic pillars and double telescopic suspension pillars. , in recent years, with the continuous development, research and practice of engineers and technicians, the support technology has made great progress and has gradually become more perfect. Wooden pillars are rarely used. Moreover, it is not uniform, and the constant increase in resistance and drop distance cannot be guaranteed; the single hydraulic prop is a new generation product developed after the single metal fricti...
