Emergency escape equipment for rail transit vehicle

Abstract

The invention belongs to the technical field of rail transit, and particularly relates to emergency escape equipment for a rail transit vehicle. Aiming at the technical problems of narrow range, ropeabrasion and damage to the outer wall of the vehicle, the emergency escape equipment comprises a hanging basket, two clamping blocks and two first supporting seats, wherein the inner walls of the twofirst supporting seats are provided with the same rotating shaft, the first supporting seats are arranged at the inner bottom of a rail transit carriage, the two sides of the outer wall of the rotating shaft are respectively provided with a rope winding roller, the outer walls of the rope winding rollers are provided with rope coils, a rope is pulled out of the rope outlet end of each rope coil, the outer wall of the rotating shaft is provided with a groove with a fan-shaped cross section, the outer wall of the rotating shaft is provided with a gear sleeve, a stop block is welded to the innerwall of the gear sleeve, and the inner wall of the gear sleeve is provided with a pressing groove. According to the emergency escape equipment for the rail transit vehicle, passengers can escape on the ground by self gravity without depending on electric power, the application range is wide, the escape safety of the passengers is improved, and the collision of the hanging basket is prevented fromdamaging the side wall of the carriage.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an emergency escape device for a rail transit vehicle. Background technique [0002] The rail transit vehicles in Chongqing generally run on the monorail at a height of about 20 meters from the ground. When the rail transit vehicle encounters an unexpected emergency stop on the monorail, it is necessary to evacuate the passengers in the vehicle to prevent accidents. Because the width of the rail transit car is greater than the width of the monorail, there is no free space on both sides of the rail transit car for passengers to get off and avoid danger, so it is necessary to use an escape device for emergency escape. [0003] Due to the high altitude of rail transit vehicles, it is generally necessary to use high-altitude escape equipment. The existing high-altitude escape equipment generally uses a motor to drive the rope roll to rotate, so that the rope is lowered, and a ha...

AI Technical Summary

Problems solved by technology

[0003] Due to the high altitude of rail transit vehicles, it is generally necessary to use high-altitude escape equipment. The existing high-altitude escape equipment generally uses a motor to drive the rope roll to rotate, so that the rope is lowered, and a hanging basket is fixed at one end of the rope, and the passenger is rescued by the hanging basket. However, due to the lack of power of the rail transit vehicle during an emergency stop, the motor will not be able to run. This kind of high-altitude escape equipment cannot be used, and it cannot escape. The scope of application is narrow, and the rope will be damaged when the hanging basket Friction with the lower edge of the window will cause the rope to be worn, the safety factor will decrease, and when the hanging basket descends, it will scrape on the outer wall of the rail transit vehicle, causing damage to the rail transit vehicle and increasing maintenance costs
