Intelligent monitoring anti-pinch lift door

Abstract

The invention discloses an intelligent monitoring anti-pinch lift door comprising a first door body, a second door body and a first rail groove. The second door body is movably arranged on one side ofthe first door body. The first rail groove is fixedly arranged on the tops of the first door body and the second door body. A second rail groove is fixedly arranged on the bottoms of the first door body and the second door body. According to the intelligent monitoring anti-pinch lift door, a human body or goods shield infrared signals transmitted by an infrared transmitter in a second light curtain, so that the infrared receiver in the first light curtain cannot receive the infrared signals, meanwhile, when a microwave sensor detects that people enter the lift, a sensing probe collects signals and generates pulse signals, then the pulse signals are transmitted to a controller, and therefore the lift door is in the open state all the time; the sensing range of the microwave sensor can be effectively expanded by a refractor, the microwave sensor and the light curtains jointly control the lift door, so that the lift door can be effectively prevented from pinching people or goods, and theintelligent monitoring anti-pinch lift door is safer in use.

Description

technical field [0001] The invention relates to an elevator door, in particular to an intelligent monitoring anti-pinch elevator door. Background technique [0002] The elevator door is a very important part of the elevator. There are two doors. The one that can be seen from the outside of the elevator and is fixed on each floor is called the hall door, and the one that is seen inside and fixed on the car moves with the car is called the car door. Door. The switch of the elevator door is generally driven by the car door to switch the hall door. Its stability, rationality and safety are the key factors to determine the elevator grade. [0003] However, the existing elevator door only has an anti-pinch protection device. When the anti-pinch function fails, it loses the anti-pinch function and is very unsafe to use. Therefore, we propose an intelligent monitoring anti-pinch elevator door. Contents of the invention [0004] The main purpose of the present invention is to pr...
