Problems solved by technology

[0003] There are two types of existing rockfall prevention methods. One is to establish permanent shielding protection devices on the mountain, but not all dangerous roads near the mountain are equipped with such devices, and these protection devices may have already The other is to use a larger diameter steel circular bellows, but this method is relatively simple, there is no mechanized erection, and vehicles cannot pass, only to ensure the safety of pedestrians

Embodiment 1

[0022] Embodiment 1: Referring to the accompanying drawings, a folding emergency passage includes: a chassis vehicle 1 serving as an equipment transportation carrier and providing erection power, a sub-frame 2, a turning mechanism 3, a portal frame 4, and a folding passage 5;

[0023] The subframe 2 is loaded on the chassis vehicle 1, and the subframe 2 includes: a frame body 21 and an outrigger cylinder 22; the vehicle frame body 21 is used to connect the chassis vehicle 1 and the hinged turning mechanism 3, and the outrigger cylinder 22 is used for It is supported on the ground during the operation to ensure the stability and safety of the chassis vehicle 1;

[0024] Turnover mechanism 3 includes: turnover frame 31, turnover oil cylinder 32, latch oil cylinder 33; turnover frame 31 is used for connecting and disengaging gantry 4, turnover oil cylinder 32 provides thrust, makes turnover frame 31 and all parts connected thereon to turn over together 90°, the bolt cylinder 33 i...

Embodiment 2

[0027] Embodiment 2: Referring to the accompanying drawings, a method for using a folding emergency passage includes the following steps:

[0028] A. Initially, the overturning frame 31 on the chassis vehicle 1 and all parts connected thereto are in a horizontal state, and the bolt cylinder 33 is in an extended state, connecting the gantry 4 and the overturning frame 31; through the chassis Vehicle 1 parks the folding emergency passage at the erection position, and unfolds the outrigger cylinder 22, so that the chassis vehicle 1 is stably supported;

[0029] B. Turn on the overturning oil cylinder 32, so that the overturning frame 31 and all the parts connected thereto can be overturned 90° backward together;

[0030] C. Open the unfolding cylinder 43 to make it retract downward, drive the pulley 51 to move downward, and the distance between the upper and lower hinge points of the X-shaped bracket 52 is reduced, so that the folding channel 5 is unfolded until it moves to the l...

Abstract

The invention belongs to mechanized road facility, in particular to a protection aisle preventing vehicles and pedestrians from being hit by falling stones. The technical scheme of the folding-type emergency aisle comprises a chassis vehicle (1), an auxiliary frame (2), an overturning mechanism (3), a door-shaped frame (4) and a folding aisle (5). The folding-type emergency aisle and the application method thereof have following beneficial effects: the requirement for driving on the road is satisfied so that the folding-type emergency aisle can rapidly reach a safeguard location and can be mechanically erected; provided is offered to the top and left and right sides; a bridge surface plate is provided for the bottom surface so that the aisle capable of carrying and blocking falling mountain stones is formed, thereby ensuring safety of vehicles and pedestrians and preventing the vehicles and the pedestrians from being hit; and meanwhile, the folding-type emergency aisle can be used for road ravines as temporary emergency bridges such that roads are unblocked.

Description

technical field [0001] The invention belongs to a mechanized road facility, in particular to a protective channel for preventing vehicles and pedestrians from being injured by falling rocks. Background technique [0002] Rockfall is a geological disaster that occurs in mountainous areas, mostly caused by crustal movement or the loosening of the hillside surface caused by rainwater erosion. After the earthquake, after the roads built on the side of the hillside are basically cleared, small falling rocks may hit passing vehicles and pedestrians, which can easily cause traffic interruptions and accidents, and seriously endanger the safety of vehicles and pedestrians. Therefore, before the disaster warning is completely lifted, it is necessary to set up a safety protection passage in the rockfall area to ensure the safety of vehicles and pedestrians, and to avoid traffic being blocked again due to accidents caused by falling rock injuries. [0003] There are two types of existi...
