Description

Elevator lifting safe operation system

Technical Field

The invention relates to the technical field of elevator lifting systems, in particular to an elevator lifting safe operation system.

Background

The elevator is a permanent transportation device which serves a plurality of specific floors in a building, the lift car of the elevator runs on at least two rows of rigid rails which are vertical to the horizontal plane or have an inclination angle smaller than 15 degrees with a plumb line, and the elevator mainly comprises a traction part, a guide part, a lift car, a counterweight and an electric control part. When the elevator works, the traction mechanism undertakes a lifting task, namely the traction wheel drives the steel wire rope to do reciprocating motion, so that the car and the counterweight at the two ends of the steel wire rope do vertical opposite motion under the limit of the respective guide mechanisms, the electric appliance control mechanism controls the car to ascend or descend as required and stop at a specified floor according to a received instruction, and the aim of vertical transportation is fulfilled.

Present elevator is in order to prevent that people from passing in and out the time all being equipped with the response by the elevator door clamp and prevents pressing from both sides protection device, but also have when the response is prevented pressing from both sides protection device inefficacy, the elevator is carried the human body and still is upwards or move downwards, the condition that leads to the vertical quilt of personnel to press from both sides casualties takes place, because present elevator does not have vertical protection device that prevents pressing from both sides, lead to in case this kind of condition takes place, must cause very big casualties accident, bring very big potential safety hazard for the people who take the elevator, therefore we have proposed an elevator lift safe operation system, a problem for solve the aforesaid and proposed.
