Hopper self-locking system

Abstract

The invention discloses a hopper self-locking system, which comprises a rail and a hopper arranged on the rail, wherein the middle part of the hopper is provided with a hopper base; the hopper base comprises a hopper framework; a hopper anti-skid device is welded on two sides of the hopper framework respectively; the middle part of the hopper framework is provided with a pulley sliding plate; a push rod is connected between the hopper anti-skid devices and the pulley sliding plate; one end of the push rod is connected to the pulley sliding plate; and the hopper anti-skid device is provided with an anti-skid device body, a safety shaft-1, a safety shaft seat board and a return spring. When the hopper of the hopper self-locking system slides down wholly because a steel wire rope is fractured suddenly, the linkage of the push rod and the safety shaft is formed because the pulley sliding plate is driven by the return spring. Because the safety shaft is pushed out for a certain distance at the same time, the outstretched section of the safety shaft can be blocked by a stop block so that the hopper cannot slide down to ensure that the hopper is basically stopped at the original position and is prevented from sliding down and being broken at a special moment.

Description

technical field [0001] The invention relates to a hopper self-locking system. Background technique [0002] The original German equipment design has shortcomings in the safety protection of the loading hopper equipment. The original design did not fully consider the self-protection problem once the wire rope breaks during the working process of dragging the hopper, that is, the problem of preventing sliding. The original equipment has no limit mechanism. , causing the hopper weighing up to 3 tons to slide rapidly along a slope of nearly 50 degrees and a height difference of nearly 6 meters under the action of its own weight, resulting in serious damage to the hopper. Many such accidents have occurred during the production process, which seriously affected production. . Contents of the invention [0003] The purpose of the present invention is to provide a hopper self-locking system that prevents the axle from rotating by setting a limiting block on the safety shaft so tha...
