Manual-automatic integrated adjustable chair blocking device of descending flying cart by mine ropeway

Abstract

The invention discloses a manual-automatic integrated adjustable chair blocking device of a descending flying cart by a mine ropeway, comprising a lifting frame; a fixed shaft is arranged on a movable plate which is arranged on the lifting frame by a U-shaped bolt; the fixed shaft is provided with a shaft sleeve which is fixed by a nut; the lower side of the shaft sleeve is provided with a baffle; the upper side of the shaft sleeve is provided with a shifting block; a traction electromagnet is arranged on the lifting frame; a pull rod of the traction electromagnet is connected with the shifting block; the electromagnet can be controlled by an over-speed safety protection circuit; a manual switch of the over-speed safety protection circuit is controlled by a pull rope; and a speed sensor is arranged at a supporting wheel side. The manual-automatic integrated adjustable chair blocking device has the beneficial effects that since the baffle is controlled by the electromagnet, when the mine ropeway operates normally, the electromagnet pulls up the baffle, so that the passing of a movable rope clip; when the mine ropeway generates power failures in operating process, and in cart flying, a lifting chair in the descending direction slides downwards and fast under the gravity function; and when the speed is detected to overpass the safety value by the speed sensor, the electromagnet pulls the baffle, the baffle moves downwards and is clamped on a steel wire rope, so that the movable rope clip can be prevented from sliding downwards, and the occurrence of casualty accidents of personnel sitting on the lifting chair can be avoided.

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 object of the present invention is achieved in the following way: a mine ropeway down-flying driver's integrated adjustable chair stop device, including a hanger, a fixed shaft is installed on the movable plate, and the movable plate is mounted on the hanger through U-shaped bolts , a shaft sleeve is installed on the fixed shaft, the shaft sleeve is fixed with a nut, a baffle is installed on the lower side of the shaft sleeve, a pulling blo...
