Elevator

Abstract

The invention relates to an elevator. The elevator comprises a lift car, sliding rails, a traction machine, traction ropes and a counterweight structure, wherein the lift car is connected with the traction ropes through a regulating device; the regulating device comprises an upper support plate and a lower support plate, regulating sliding grooves are formed in the opposite surfaces of the upper support plate and the lower support plate, the upper supply plate and the lower support plate are connected through regulating rods, and sliding heads at the two ends of each regulating rod are arranged in the regulating sliding grooves in the upper support plate and the lower support plate in a sliding manner; electromagnetic columns are embedded in the sliding heads; in the same regulating sliding groove, the magnetic force of the electromagnetic columns in the adjacent sliding heads is repellent; and a pedal is arranged on the inner bottom surface of the lift car, and pressure-sensitive pieces are arranged into an array on the surface of the pedal at equal intervals. The elevator is novel in structure and unique in principle and can intelligently regulate the traction positions of the traction ropes according to the distribution condition of passengers in the lift car, so that the uniform stress of each traction rope is ensured, the stable lifting of the lift car is promoted, the safety of the elevator is effectively improved, and the working efficiency is increased.

Description

technical field [0001] The invention relates to a lifting and carrying mechanism, in particular to an elevator. Background technique [0002] Elevator is a necessary vehicle for high-rise buildings at present. According to the driving mode, elevators can be divided into traction drive and hydraulic drive. Among them, traction drive has many advantages such as safety and reliability, unlimited lifting height, and easy control of elevator speed. , so the traction-driven elevator has gradually become the mainstream of elevator products; the traction-driven elevator includes a car, a traction system and a counterweight system, and the car is lifted and lowered by traction ropes and traction machines. Connected to the top of the car, the direction of the traction resultant force of the traction rope passes through the center of gravity of the car, so as to ensure that the car can rise and fall smoothly; but in actual use, passengers will not be evenly distributed in the car , th...

[0002] Elevator is a necessary vehicle for high-rise buildings at present. According to the driving mode, elevators can be divided into traction drive and hydraulic drive. Among them, traction drive has many advantages such as safety and reliability, unlimited lifting height, and easy control of elevator speed. , so the traction-driven elevator has gradually become the mainstream of elevator products; the traction-driven elevator includes a car, a traction system and a counterweight system, and the car is lifted and lowered by traction ropes and traction machines. Connected to the top of the car, the direction of the traction resultant force of the traction rope passes through the center of gravity of the car, so as to ensure that the car can rise and fall smoothly; but in actual use, passengers will not be evenly distributed in the car , the position of the center of gravity of the car shifts; this situation easily causes uneven force on each traction rope, making one of the traction ropes reach the traction limit, and the car alarm sounds; however, there are still There is a lot of space, but the elevator will not run normally; this situation will easily lead to unstable operation of the car, and more likely to cause wear and tear on the traction rope and the car, posing a greater safety hazard; at the same time, it will affect the maximum carrying capacity of the car. Congestion of upstairs and downstairs during peak hours of flow of people
