Embodiment
[0027] Example: as attached figure 1 , 2 , 3, 4, 5 and attached Figure 6 As shown, the elevator light curtain reliability life test device is characterized in that: it includes a first frame 2 for setting the light curtain 1 and a second frame 4 for setting the shielding unit 3, which is moved and set on the The first mobile unit 5 on the second frame 4 and the second mobile unit 6 arranged on the first mobile unit 5 are moved by rack engagement to realize the occlusion test of the light curtain 1, so The light curtain 1 is connected with a light curtain action recorder.
[0028] In this embodiment, the first moving unit 5 is used to drive the shielding unit 3 to move left and right between the light curtains 1, and the second moving unit 6 is used to drive the shielding unit 3 to move between the light curtains 1 The light curtains 1 move up and down, so that the shielding unit 3 realizes all-round shielding of the light curtains, that is, simulates all shielding situatio...

The invention belongs to the technical field of elevator light curtain testing equipment, and particularly relates to elevator light curtain reliability service life testing equipment. The elevator light curtain reliability service life testing equipment comprises a first frame which is used for arranging the light curtain and a second frame which is used for arranging a shielding unit, the shielding unit comprises a first movable unit which is movably arranged on the second frame through a method of rack meshing and a second movable unit which is movably arranged on the first movable unit through the method of rack meshing, thus the shielding testing on the light curtain is achieved, and the light curtain is connected to a light curtain movement recorder. According to the elevator light curtain reliability service life testing equipment, by conducting movement in four directions of up, down, left and right in the elevator light curtain, the comprehensive shielding testing is conducted, and by coordinating with a method of recording a displacement distance, the whole everyday simulation shielding testing on the elevator light curtain and the shielding position calculating detecting when the shielding does not response are completed. The elevator light curtain reliability service life testing equipment has the advantages that the structure is simple and reasonable, the light curtain service life testing is effective and convenient, the shielding movement coverage is complete, and the detecting at the position where the shielding does not response is accurate.
Description
technical field [0001] The invention belongs to the technical field of elevator light curtain detection devices, and in particular relates to an elevator light curtain reliability life test device. Background technique [0002] Elevator light curtain is a light-type elevator door safety protection device, which is suitable for passenger elevators and freight elevators to protect the safety of passengers. The elevator light curtain is composed of an infrared transmitter and an infrared receiver. The transmitter and the receiver are respectively arranged in a straight line with several pairs of infrared emitting tubes and infrared receiving tubes. The infrared emitting tube emits a conical infrared beam. In addition to the transmitting signal of the tube, it can also receive the signals of the upper and lower adjacent transmitting tubes one by one to form a cross beam, so as to realize a denser infrared protection light curtain network. When any beam of light of the elevator ...
