Problems solved by technology

[0008] It can be seen that the existing technical measures are a system of "stopping the movement", which has the characteristics of "post-processing", and in this state, the car has already started to move, which brings certain safety threats and psychological shadows to the occupants. It will cause certain impact damage to the relevant mechanisms and parts of the elevator, which is not conducive to the safe use of the elevator

Embodiment Construction

[0040] The present invention is described in detail below in conjunction with accompanying drawing:

[0041] In a first aspect, the present invention provides an elevator parking system, comprising: a parking brake arranged on an elevator suspension device, a trigger device for triggering the action of the parking brake, and a control module connected to the trigger device;

[0042] The working state of the parking brake is: it is in the standby state when the elevator is running normally. After the trigger device moves (release after power failure), at this time, the friction element of the brake is clamped on the braked part of the elevator and maintains a certain braking force; After the element is released, the elevator runs.

[0043] After the elevator stops and the door is opened, the parking brake starts to act, and there is no actual relative movement with the braked parts of the elevator. There is no friction braking to stop, and it only provides the parking function...

Abstract

The invention discloses an elevator stopping parking system and a control method thereof. The system includes comprises a parking brake arranged on an elevator suspension device, a trigger device for triggering the action of the parking brake, and a control module connected with the trigger device; when the elevator is in normal operation, the control module controls the parking brake to be separated from a braked part of the elevator through the trigger device; when the elevator stops and opens the door, the control module controls the parking brake to be tightly clamped on the braked part of the elevator through the trigger device; when the elevator closes the door and sends out an operation instruction, the control module controls the parking brake to be separated from the braked part of the elevator through the trigger device, and the elevator runs. The elevator stopping parking system and the control method have the advantages of preventive elevator accident movement protection measures that stopping (drive motor zero turn) is conducted for braking, no friction occurs in the braking process, and the wear of brake materials is not produced, so that the environmental impact caused by the friction is not produced.

Description

technical field [0001] The invention relates to the technical field of elevator products, in particular to an elevator parking system and a control method thereof. Background technique [0002] Most of the elevator injury accidents occurred during the door opening and closing after the elevator car stopped. Injury incidents that people or objects entering and leaving the car are cut due to accidental (up and down) movement of the car occur from time to time. Although the elevator is equipped with a car accidental movement protection device, it tries to prevent the car from moving unexpectedly when the brake of the main drive fails, any single component of the drive control system fails, or the traction conditions are damaged, causing the wire rope to slip on the traction sheave, etc. However, since the device does not start during the normal operation of the elevator and the mechanism therein is idle for a long time, it is very easy to cause failure due to looseness and jam...
