A detection device for mechanically detecting unexpected movement of an elevator car

Abstract

The invention discloses a detection device for mechanically detecting unexpected movement of an elevator car, which relates to the field of detection technology. Aiming at the problem that existing elevators may cause casualties, the following scheme is proposed, which includes a casing, and the casing It is a rectangular cavity structure, and the four side walls of the housing are provided with openings, and the openings are movably connected with a rectangular frame, and one end of the rectangular frame located outside the housing is rotatably connected with two roller sets, and each roller set It includes two rollers, and one end of the rectangular frame inside the housing is fixed with a baffle. In the present invention, through the setting of structures such as motors and spring scales, the motor car can be pulled, and the braking capacity of the elevator can be tested to prevent the elevator from slipping easily due to the decline in the braking force of the elevator. The setting of such structures can make the device stop in the elevator installation shaft, let the elevator run to pull the device, and the traction force of the elevator can be tested.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a detection device for mechanical detection of unexpected movement of an elevator car. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. [0003] If the elevator moves unexpectedly when it is working, it will pose a threat to the safety of passengers, and seriously cause casualties to passengers. Therefore, we propose a detection device for mechanical detection of accidental movement of the elevator car to solve the problem. above question. Contents of the invention [0004] The obje...
