Problems solved by technology

However, many old buildings did not have elevators, so now there is a great demand for elevators in old buildings. At the same time, villas also need to install elevators. Old buildings are usually multi-storey with about six floors, and the number of floors in villas and old buildings is relatively low.
[0003] The existing elevator car is usually raised and lowered by wire rope. This method has poor stability, and the car will shake during the process of starting and stopping. If the wire rope breaks, it will cause a well accident and poor safety performance. The bottom of the existing elevator shaft is mostly equipped with a shock absorbing mechanism, but the existing shock absorbing mechanism is mostly fixed, which takes up a large space. It is necessary to dig deep down the elevator shaft to install the shock absorbing mechanism, which increases the construction difficulty and cost

Abstract

The invention discloses an elevator shock absorbing device. A lead screw is provided in an elevator shaft, wherein a speed sensor is arranged in the elevator shaft, the figure is not visible, a firstmotor, a first speed reducer, a worm and a shell are arranged on the left side of a car, the lead screw passes through the shell, the shell is provided with a worm gear, the lead screw passes throughthe worm gear and is screwed with the worm gear, the output end of the first motor is connected with the input end of the first speed reducer, the output end of the first speed reducer is connected with the worm, and the worm penetrates into the inside of the shell and is matched with the worm gear. The driving method of the lead screw as well as the worm gear and the worm can ensure that the caris lifted more smoothly, and at the same time, the car can be driven by the lead screw to form a self-locking manner, preventing the car from falling, and the reliability is good. Four shock absorbingmechanisms are arranged at the bottom of the elevator shaft, and a second motor is arranged at the bottom of the elevator shaft. The second motor is connected to the four shock absorbing mechanisms through a transmission mechanism, and the four shock absorbing mechanisms rotate synchronously. One motor can complete the action, reducing costs and being practical.

Description

technical field [0001] The invention relates to the technical field of elevator fall prevention, in particular to an elevator shock absorbing device. Background technique [0002] With the rapid development of the national economy and the construction of urbanization, various high-rise buildings have sprung up. Elevators have become indispensable transportation equipment in people's lives. However, many old buildings did not have elevators, so now there is a great demand for elevators in old buildings. At the same time, villas also need to install elevators. Old buildings are usually multi-storey with about six floors, and the number of floors in villas and old buildings is relatively low. . [0003] The existing elevator car is usually raised and lowered by wire rope. This method has poor stability, and the car will shake during the process of starting and stopping. If the wire rope breaks, it will cause a well accident and poor safety performance. The bottom of the exis...
