Elastic footboard structure of self-rescue device when elevator falls

Abstract

The invention provides an elastic footboard structure of a self-rescue device when an elevator falls and relates to the self-rescue device when the elevator falls. Shock absorption springs (23) are sleeved on screw rods (21) which are spaced on the lower portion surface of a footboard (8). The lower portions of the screw rods penetrate through circular holes (28) in multiple long board bodies (24). A self-locking nut (15) is arranged at the lower end of each screw rod. A semicircle board B (22) in the rear portion of each long board body is buttoned on the upper portion of a lower portion rod(9). A semicircle board A (13) of each short board body is buttoned to the lower portion of the lower portion rod and fixed by corresponding locking screws (36). A cross arm bar 10 is arranged in thefront lower portion of a square frame bar. Shock absorption springs are arranged in lifting pipes. The upper portions of upper column bodies (17) abutting against the upper ends of shock absorption springs are fixed to the inner wall of a lift car, and the lower ends of lower column bodies (12) abutting against the lower ends of the shock absorption springs are connected with the ground surface ofthe lift car. According to the elastic footboard structure of the self-rescue device when the elevator falls, a person stands on the footboard after the footboard is turned down when the elevator falls, both hands of the person hold onto an upper handle lever, and the injury risk of the crew taking the elevator can be effectively lowered by means of elasticity of the shock absorption springs.

Description

【Technical field】 [0001] The invention relates to an elevator falling self-rescue device, in particular the invention relates to an elastic pedal structure of the elevator falling self-rescue device. 【Background technique】 [0002] At present, with the rapid advancement of urban construction, a large number of residential buildings, office buildings, office buildings, shopping malls and hotels with high floors have been constructed. In order to facilitate people to go up and down, buildings with more than six floors are equipped with shaft elevators; because Due to various reasons such as long-term disrepair, product quality, etc., a very small number of elevators will suddenly fall during operation; the reason for the sudden fall of the elevator is mainly caused by the failure of the speed limiter and safety gear at the same time; the existing prevention methods are: 1. Keep calm when the elevator falls. Use the emergency power button inside the elevator, which can be press...

Problems solved by technology

6. Don't lean on the elevator door. If the elevator door stops in the middle of the landing, the elevator door opens suddenly, which is easy to cause injury, or other elevator doors get stuck, or even fall into the hoistway

Although the above methods can reduce the harm to the human body, they are limited to the structural restrictions in the elevator car, and there are still a small number of casualties
