Manual-automatic integrated fixed baffle chair device of descending runaway of mine ropeway

Abstract

The invention discloses a manual-automatic integrated fixed baffle chair device of a descending runaway of a mine ropeway, comprising a suspension bracket. A fixed shaft is mounted on the suspension bracket and provided with a shaft sleeve which is fixed by nuts, a baffle is mounted at the lower side of the shaft sleeve, a poker block is mounted at the upper side of the shaft sleeve, a traction electromagnet is mounted on the suspension bracket, the traction electromagnet pull rod is connected with the poker block, the electromagnet can be controlled through an overrunning safe protective circuit, a manual switch of the overrunning safe protective circuit is controlled through a stay cord, and a speed sensor is arranged at the riding wheel side. The invention has the advantages that because the baffle is controlled by the electromagnet, the baffle is pulled up by the electromagnet without preventing a movable rope clip from passing when the mine ropeway runs normally; and when the power failure occurs in the operation process of the mine ropeway to cause runaway, and a suspension chair in the descending direction rapidly slide downwards under the action of gravity, the baffle is pulled up by the electromagnet and moves downwards to be clamped on a wire cable when the speed detected by the speed sensor exceeds a safety value so as to prevent the movable rope clip from sliding downwards and avoid the casualty accidents of persons sitting on the suspension chair.

Description

technical field [0001] The invention relates to a seat blocking device for a mine-used cableway speed car. Background technique [0002] During the operation of the mining ropeway, due to power failure, the hanging chair in the downward direction slides down quickly under the action of gravity, resulting in a speeding phenomenon, causing casualties of passengers. Contents of the invention [0003] The object of the present invention is to provide a chair blocking device for anti-flying cars when going down a mine cableway. [0004] The purpose of the present invention is achieved in the following manner: a mine ropeway down-flying driver's self-integrated fixed chair device, including a hanger, a fixed shaft is installed on the hanger, a shaft sleeve is installed on the fixed shaft, and a nut is used for the shaft sleeve Fixed, a baffle is installed on the lower side of the bushing, a pulling block is installed on the upper side of the bushing, an electromagnet is install...
