Description

Technical Field

[0001] This utility model relates to the field of elevator inspection and testing, and in particular to an elevator door gap detection device. Background Technology

[0002] In the existing safety technical specifications, the inspection and testing of elevator car doors requires a certain force to pry open the two doors of the elevator to test the door gap. The gap after the doors are closed is measured to see if it meets the following requirements: (1) The gap between the door leaves and between the door leaves and the columns, lintels and sills shall not exceed 6mm for passenger elevators and not exceed 10mm for freight elevators; (2) In the direction of the fastest opening of the horizontal sliding landing door and the folding landing door, a force of 150N shall be applied to the most unfavorable point. The gap mentioned in item (2) of this article shall not exceed 30mm for side-opening doors and the total gap for center-opening doors shall exceed 45mm. However, in actual operation, it is often necessary to manually pry open the doors, which is not only unsafe, but also the force required to pry open the doors cannot be guaranteed, affecting the inspection and testing effect.

[0003] Therefore, an elevator door gap detection device is needed to solve the above problems. Utility Model Content

[0038] In one embodiment of this utility model, the first sliding rod 120 is a square rod or a round rod.

[0040] In one embodiment of the present invention, the upper surface of the detection part 14 is provided with a scale, and the scale of the detection part 14 is used to detect the distance at which the detection part 14 is inserted into the gap of the elevator door.

By adjusting the depth of the support part inserted into the support slot, the displacement between the two support frames is adjusted, and thus the pressure on the spring 152 is adjusted, thereby adjusting the force used to open the two elevator doors.

[0050] Secondly, the adsorption unit can adsorb the elevator door gap detection device onto the corresponding elevator door, making it easy to operate.
