Quarry side slope rolling stone deceleration protection facility quarry

Abstract

The invention discloses a quarry side slope rolling stone deceleration protection facility. The quarry side slope rolling stone deceleration protection facility comprises two rows of ejection cavitieswhich are distributed on a side slope and have upward openings, wherein a trigger deceleration device is arranged in the ejection cavities, the trigger deceleration device comprises an ejection blockwhich can slide up and down and is arranged in the ejection cavities, a first spring is fixedly connected between the lower end of the ejection block and the inner wall of the ejection cavities, a reset device is arranged below the trigger deceleration device, and a rolling stone recovery device is arranged on the right side of the trigger deceleration device and the reset device. The quarry sideslope rolling stone deceleration protection facility can effectively reduce the sliding risk of side slope rolling stones in places such as quarries, small rolling stones which are easy to ignore cannot slide down to cause harm while the quarry side slope rolling stone deceleration protection facility is served as a dustproof effect in daily life, the rolling stone speed can be effectively reduced when large rolling stones slide down, sufficient evacuation time is provided for personnel in a dangerous area below the side slope, and a recovery hanging net convenient for rolling stone recoveryis arranged.

Description

technical field [0001] The invention relates to the technical field of disaster prevention and reduction, in particular to a deceleration protection facility for rolling stones on a slope of a quarry. Background technique [0002] Due to the needs of construction and industrial development, quarrying and mining have become an indispensable part of the development path. In quarries or pits, accidental high-slope rolling stones are very likely to occur, ranging from equipment damage to severe It will endanger the life safety of personnel and cause major production accidents. The current early warning system for rolling stones is extremely simple. Due to the suddenness and rapidity of rolling stones, it is impossible to effectively intercept the initial stage of rolling stones, and it is also unable to notify the danger zone in time. The rapid evacuation of personnel, resulting in a serious accident is likely to occur once it occurs. The present invention illustrates a device ...
