Semi-automatic liftable slope surface stone blocking device

Abstract

The invention discloses a semi-automatic liftable slope surface stone blocking device and belongs to the technical field of environmental protection. The slope surface stone blocking device comprises a lifting device, a stone blocking net, steel wire ropes slidably mounted on the lifting device, and drive devices for driving the steel wire ropes to slide, wherein the stone blocking net and each drive device are connected to the two ends of the steel wire rope respectively. According to the slope surface stone blocking device, dangerous rocks on a high and steep slope are dynamically protected, the slope surface is locally positioned and protected, a worker can finish a series of operations of lifting the stone blocking net, recovering fallen stone, transferring equipment and the like by operating mechanical equipment in a relatively safe position at the top of the slope, the construction site is prevented from being occupied, and the construction safety is improved.

Description

technical field [0001] The invention relates to a liftable semi-automatic rock blocking device on a slope, which belongs to the technical field of environmental protection. Background technique [0002] At present, the traditional stone blocking net is fixed by anchor rods, steel columns, support ropes and anchor ropes, and the flexible net is installed linearly near the foot of the slope at a certain angle to form a barrier structure in the form of a fence. When the dangerous rock on the slope collapses, although the above-mentioned rock-blocking net can play a certain role in intercepting and protecting, but for the distribution characteristics of the dangerous rock on the slope surface: the whole is scattered, and the local concentrated high and steep slope, the above-mentioned rock-blocking net is still There are obvious deficiencies, which are mainly manifested in four aspects: [0003] 1. The traditional stone blocking net can only be fixed at a certain position for s...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional stone blocking net can only be fixed at a certain position for static protection. When the position to be protected changes, a new stone blocking net can only be added, which increases the construction cost and floor area

[0004] 2. The traditional stone blocking net adopts regional protection measures, and the protection lacks local pertinence. Therefore, it usually needs to occupy more construction sites during the construction of the stone blocking net, and the construction cost is relatively high

[0005] 3. When recycling the falling rocks intercepted by the traditional stone blocking net at the foot of the slope, the uneven bottom surface of the slope foot brings great trouble to the recycling and processing of the falling rocks

[0006] 4. The dangerous rock on the high and steep slope has high gravitational potential energy. When the dangerous rock collapses and rolls to the foot of the slope, the kinetic energy converted from the gravitational potential energy makes the falling rock have a strong impact on the rock-blocking net, causing the blocking Damage to the stone net, even breaking through the stone net
