Abstract

The invention discloses a deformation measurement instrument for an elevator door. The deformation measurement instrument comprises a supporting device, a first augmentor, a force sensor and a display device, and the display device is used for receiving and processing loading force detected by the force sensor and displaying the loading force through a display screen of the display device. According to the device special for deformation tests of the elevator door, according to the compressive strength stipulation for the elevator door in new national standards, a handle drives a screw rod for transmission, rated thrust is applied to push a standard butting end to act on the elevator door, the magnitude of the loaded thrust is detected through the force sensor, and the thrust is displayed through the display device. The deformation measurement instrument is ingenious in structure, and the handle type operation is simple, practical and efficient.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator door deformation measuring instrument. Background technique [0002] According to the requirements of GB7588-2003 "Elevator Safety Manufacturing and Installation Safety Code", when the elevator landing door is in the locked position, all landing doors and their locks should have the following mechanical strength: [0003] a) Use a static force of 300N to act vertically on any position on any surface of the door leaf or door frame, and evenly distribute it within 5cm 2 When on a circular or square area, it shall: [0004] 1) The permanent deformation is not more than 1mm; [0005] 2) The elastic deformation is not greater than 15mm; [0006] After the test, the safety function of the door is not affected. [0007] b) Use a static force of 1000N to act vertically on any position on any surface of the door leaf or door frame, and evenly distribute it over 100cm 2 There shal...
