Detecting device for mechanically detecting accidental movement of elevator car

Abstract

The invention discloses a detecting device for mechanically detecting accidental movement of an elevator car, and relates to the technical field of detection. In view of the problem that an existing elevator may cause casualties, the following scheme is proposed. The detecting device comprises a shell, the shell is of a rectangular cavity structure, the four side walls of the shell are provided with openings, rectangular frames are movably connected to the openings, the end, located outside the shell, of each rectangular frame is rotatably connected with two roller groups, each roller group comprises two rollers, and the end, located in the shell, of each rectangular frame is fixedly provided with a baffle. According to the detecting device, through the arrangement of a motor, a spring scale and other structures, a motor car can be pulled, the braking ability of an elevator can be tested, and the condition that the elevator is prone to sliding due to reduction of brake force of the elevator is prevented; and through the arrangement of the rollers, brake pads and other structures, the device can be stopped in an elevator installation hoistway, the elevator runs 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...
