Elevator automatic rescue device

Abstract

Disclosed is an automatic rescue apparatus for an elevator. The apparatus comprises a base (A), a motor (11), an input shaft (111), a linkage gear (122), a worm gear (12), a worm screw (121), a reduction gear set (13), a bobbin line disk (14), and a steel cable (2). The motor (11) is connected to the input shaft (111). The input shaft (111) is provided with a thread segment (112). The input shaft (111) is meshed with the worm gear (12) by means of the thread segment (112). The worm gear (12) is connected to the worm screw (121). An outer end of the worm screw (121) is provided with the linkage gear (122). The linkage gear (122) is meshed with a bull gear (131) of the reduction gear set (13). One end of the bobbin line disk (14) is provided with a gear (141). The gear (141) is meshed with a pinion gear (132) of the reduction gear set (13). The steel cable (2) is wound on the bobbin line disk (14). The apparatus has a scientific and proper design, is convenient and practical, and can enable an elevator car to be stably lowered to the position of an elevator door of a nearest floor when a power failure or fault occurs, thereby allowing a person taking the elevator to successfully escape.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator automatic rescue device. Background technique [0002] Now, due to my country's dense population, various buildings are generally built higher and higher, and there are more and more floors. For the convenience of people, they can easily go up and down the floors, and arrive at the desired floors conveniently. Elevators are generally provided in tall buildings. The common elevator equipment is that several cable pulleys are arranged on the top of the elevator car. After the steel cables go around the cable pulleys, one end of the steel cables is fixed upwards and fixed in the machine room to form a fixed end, and the other end is wound upwards through the machine room. The main engine of the motor is fixedly connected downwards on a heavy block, and the main engine of the motor is used to drive the steel cable to pull the elevator car to move up and down. [0003] Although s...

Problems solved by technology

However, such a design will cause the elevator car to stop between the two floors, making rescue difficult, and sometimes limited by the location, it is impossible to successfully pry open the elevator door for rescue. At this time, the passengers in the elevator car can only wait for recovery. After power supply or troubleshooting, let the elevator stop in front of the elevator doors on each floor to open the elevator door and the door of the elevator car to let the passengers out of trouble. During the waiting period, it will not only waste the time of the passengers, but also cause them psychological panic.
