Pneumatic car blocking door of inclined drift

Abstract

The invention provides a pneumatic car blocking door of an inclined drift. The pneumatic car blocking door of the inclined drift comprises a car blocking door frame, a blocking rod and a control air cylinder, wherein the car blocking door frame comprises a left upright rod and a right upright rod which are parallel with each other; the left upright rod and the right upright rod are fixedly arranged on two sides of a tramcar track in the inclined drift respectively; a left accommodation groove and a right accommodation groove are formed in the left upright rod and the right upright rod respectively; the left accommodation groove and the right accommodation groove extend along the length directions of the left upright rod and the right upright rod respectively; the blocking rod is perpendicular to the left upright rod and the right upright rod; moreover, the left end of the blocking rod is put in the left accommodation groove; the right end of the blocking rod is put in the right accommodation groove; the left end part and the right end part of the blocking rod are connected with a left pull rope and a right pull rope respectively; the left pull rope and the right pull rope are connected onto a piston rod of the control air cylinder; the control air cylinder is connected with an air source through an air pipe; and a control valve is arranged on the air pipe. With the adoption of the pneumatic car blocking door of the inclined drift provided by the invention, the automation can be realized and the operation is convenient and labor-saving.

Description

technical field [0001] The invention relates to a safety device in a mine or a tunnel or itself, in particular to a car door for an inclined lane. Background technique [0002] The safety management of underground auxiliary transportation has always been the weak link of coal mine safety production, especially in the process of inclined roadway transportation, the situation of inclined road sports cars hurting people or damaging facilities often occurs. An important technical means of transportation safety. However, most of the protective devices commonly used today, such as manual retaining beams, double-track car arresters, and kowtow bugs, require manual operation, which is low in automation, inconvenient to operate, and labor-intensive for workers during the operation. Contents of the invention [0003] The object of the present invention is to provide a wind-operated door for inclined lanes, which can be automated, and is easy to operate and labor-saving. [0004] I...
