Elevator with multi-stage safety protection

Abstract

The invention relates to an elevator with multi-stage safety protection. Working ropes and safety ropes are arranged on the elevator, the elevator comprises at least one safety device, each safety device is arranged on the elevator and fixedly connected with the elevator, each safety device is glidingly connected with each working rope and each safety rope, respectively, a plurality of safety devices are symmetrically distributed and / or in stage-by-stage sequential connection, the stage-by-stage sequential connection means that the safety rope of the previous safety device is used as the working rope of the next safety device, and when a transmission rope of the electronically-controlled elevator breaks suddenly, each safety device can realize a self-locking function rapidly, so that the safety of the elevator is improved, and personal casualties are avoided; and the elevator is provided with the plurality of safety devices for multi-stage protection, so that the reliability is improved.

Description

technical field [0001] The invention relates to the field of electronically controlled elevators, in particular to an elevator with multi-level safety protection applied in the maintenance and overhaul of wind power generators. Background technique [0002] As a clean and renewable energy, wind energy has attracted more and more attention from all over the world, and its reserves are extremely huge. As one of today's new energy industries, wind power has developed rapidly due to its environmental protection and energy conservation. It has tens of thousands of wind power generating units and still has a momentum of rapid development. Under such circumstances, how to ensure the normal operation of a large number of wind turbines has become a very important issue. The working mode and installation pattern of the wind power generating set determine that the workload of overhaul and maintenance in its whole life is very heavy. In order to ensure the normal operation of wind tur...

As the name suggests, a "climbing aid" is a machine that helps people climb. In actual use, the biggest disadvantage of the "climbing aid" is that it does not make people out of climbing, and there are the following shortcomings: First, the man-machine needs to cooperate , people who do not cooperate well will be passive; second, the speed is slow and the efficiency is low, the climbing speed of the "climbing aid" is constant, and the control operating system is relatively single, which cannot maximize the work efficiency; the third is the low safety factor. , once the man-machine is well coordinated, the personnel may be in danger; the fourth is that when the operator is mentally fatigued, it is easy to collide during the climbing process, causing personal safety accidents and reducing the safety factor; When the fan needs to replace parts, people need to climb with heavy loads; Sixth, the cost is high. Compared with the simple function and structure of the "climbing aid", its relatively high cost and relatively low input-output ratio

This solves the labor intensity of maintenance personnel and initial installers climbing up and down using vertical steps, and can also carry tools and a small amount of materials for maintenance personnel and fan installation personnel, but it does not involve the safety protection device of the elevator

Due to the high height of the air duct of the generator set, in case of a problem, the consequences will be unimaginable, so the safety of the lifting structure is a big problem
