Traction self-adjusting elevator

Abstract

The invention relates to a traction self-adjusting elevator, which includes a car, a traction rope, a traction machine and a counterweight device; The seat plate is provided with a reel on the lower surface of the base plate; each reel is powered by an independent drive, and each drive is electrically connected to a controller; the reel is wound on the reel There are adjustment cables, and the joints between each adjustment cable and the car are evenly distributed on the top of the car in the circumferential direction; a pedaling monitoring board is laid on the inner bottom of the car, and pressure-sensitive sheets are arranged in an equidistant array on the surface of the pedaling monitoring board. The pressure-sensitive sheet is electrically connected to the controller; the elevator can automatically fine-tune the pull of the traction rope to the car according to the station distribution of passengers in the car, thereby optimizing the force of each traction rope and effectively reducing Reduce the loss of traction rope and car, and improve the stability of elevator operation.

Description

technical field [0001] The invention relates to an elevator, in particular an elevator capable of optimizing traction. 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 ca...

[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 , so that the weight of the car is caused, and the position of the center of gravity of the car changes; 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; therefore, often There is still a lot of space in the elevator car, but the car safety alarm has sounded; this situation is likely to cause instability in the operation of the car, more likely to cause wear and tear on the traction rope and the car, and at the same time affect the maximum carrying capacity of the car.
