This utility model provides a rapid installation and positioning device for elevator guide rails, relating to the field of elevator guide rail installation technology. It includes a workbench, several laser emitting modules, a laser receiving module, and an infrared transmitter. The laser emitting modules are installed around the bottom of the elevator shaft and positioned close to the elevator guide rail installation location. Mounting seats are fixedly installed on both sides of the workbench's upper surface near the elevator guide rail. The spacing is adjusted by moving two sliders within a horizontal frame at the top, and the sliders are moved by rollers until they abut against the inner wall of the elevator shaft, thus fixing the workbench inside the shaft and preventing it from shaking. The laser emitting and receiving modules are used in combination to quickly adjust the position of the infrared transmitter. The infrared laser beam generated by the transmitter is positioned to fit against the surface of the elevator guide rail, facilitating rapid positioning during installation.

This utility model provides an intelligent sensor-type elevator door anti-pinch protection device, relating to the field of elevator door anti-pinch protection technology. It includes two sets of detection mechanisms, each consisting of two symmetrically arranged transmitter boxes and receiver boxes with their openings facing each other. The transmitter boxes of the two detection mechanisms are respectively installed on the top edge of the elevator car door and the top of the elevator door frame. Before the elevator door begins to close, the beam of light emitted by the infrared laser transmitter passes through the space between the elevator doors and is received by the infrared laser receiver on the opposite side. If an object or person enters the space between the elevator doors during this process, it will block the infrared laser beam, causing the receiver to be unable to receive the light signal. This detection method is real-time and can detect the presence of an object or person before they come into contact with the elevator door.
