Escape device used in lifter or elevator

Abstract

The invention discloses an elevator or elevator relieving device, which is characterized by the following: at least a plurality of alternate coil assembly is installed in permanent magnetism drive motor; the alternate electric power supply power of alternate coil assembly makes the alternate coil assembly and base coil of permanent magnetism drive motor separate or act in conjunction; the delayed-elevating gear is installed; the chief axis sleeve of delayed-elevating gear installs immobilizing member; the spinning by one side of controlling device controlling the chief axis of delayed-elevating device makes the immobilizing member relieve brake equipment or spark electromagnetic contactors; which makes the elevator or elevator wagon lift and stop; the controlling device is handed by electromagnetic actuator or hand wrench grip which is fit for reset device of up-down tunnel every floor making the controlling device reset to reflex the relative relation between immobilizing member and brake equipment and electromagnetic contactors; making the wagon delayed-brake till stop is useful for the insiders to open the door to relieve easily.

Description

technical field [0001] The present invention relates to a lift or elevator trouble-relieving device, which mainly uses a backup coil group and backup power, cooperates with a slow lifting device, a control mechanism and a reset device, and can use electric power when the elevator or elevator breaks down. Or manual operation, so that the car can gradually rise or fall to the correct position on the floor by relying on the return device, so that the internal personnel can open the car door and get out of trouble. Background technique [0002] Due to the development of construction technology, high-rise office buildings, residences and factory buildings have become the trend of construction. For the connection of each floor and the entry and exit of personnel and goods, such high-rise buildings are often equipped with elevators or lifts. , so that the entry and exit of personnel and goods and the up and down are more time-saving and labor-saving. [0003] As far as the structu...

Problems solved by technology

[0006] The aforementioned backup power is applicable only when the permanent magnet drive motor and other parts are functioning normally. If the permanent magnet drive motor and other parts of the elevator are damaged or malfunction and cause the elevator to stop, the backup power cannot be used at all. function, resulting in the embarrassment of internal personnel trapped in the elevator car. Although the general elevator car is equipped with a manual opening door device to allow the internal personnel to escape, if the elevator car is not at the correct position on the floor, the internal personnel may want to get out of the car. When climbing out of the elevator, there is a danger of falling accidentally. Therefore, when the elevator stops due to power failure or failure, how to make the internal personnel safely get out of trouble has become a major issue to be solved by the present invention.
