Problems solved by technology

The brake of the cableway is an important part of the cableway equipment. The cableway is equipped with braking devices such as working brakes and emergency brakes. The braking methods include manual control brakes or program control brakes. The braking is all realized by the traction cable. Once the traction cable breaks, the emergency and safe braking of the trolley cannot be realized, which may easily cause safety accidents

Abstract

The invention discloses a pulley braking device. A brake shaft is arranged inside a sliding slot in an inner wallboard in sliding fit; friction wheels opposite to a pulley are arranged at the two endsof the brake shaft; a non-braking state of the brake shaft is limited by a resetting pull hook hinged to the inner wallboard and connected with a pull rope; a braking state of the brake shaft is realized by a tension spring connected with the brake shaft and the inner wallboard; a pawl is fixed to the inner wallboard on one side of the brake shaft through a rotating shaft; one side of the pawl islimited by a supporting shaft, and a self-rescuing rope is connected to the tail end of the pawl on the side; the pawl on the side is connected with the resetting pull hook through a resetting springso as to achieve resetting of the resetting pull hook; the other side of the pawl hooks the brake shaft in the braking state through a hook. The pulley braking device can achieve emergent and safe braking of the pulley in time so as to guarantee the safety of passengers; in the braking state, the passengers can pull down the self-rescuing rope to achieve slow sliding to a next stop, so that a self-rescuing purpose is achieved.

Description

technical field [0001] The invention belongs to the technical field of cableway auxiliary devices, and in particular relates to a pulley braking device. Background technique [0002] The cable car is driven by a driving motor to drive the steel wire rope, and the traction carriage runs along the track laid on the ground or with a certain slope to lift or lower the transportation equipment for people and goods. It is mostly used as a means of transportation in industrial and mining areas, cities or scenic spots. . Cable cars are generally divided into single-track and double-track, and those that run overhead are also called cableways. The brake of the cableway is an important part of the cableway equipment. The cableway is equipped with braking devices such as working brakes and emergency brakes. The braking methods include manual control brakes or program control brakes. The braking is all realized by the traction cable. Once the traction cable breaks, the emergency and s...
