Escalator driving wheel wear detection device and diagnosis method

Abstract

The invention relates to the technical field of escalators, and discloses an escalator driving wheel wear detection device and a diagnosis method. The escalator driving wheel wear detection device comprises a detection seat, wherein the bottom end of the front inner wall of the detection seat is provided with a chute A, the inner wall of the chute A is sleeved with a slider A, the front of the slider A is fixedly connected with a connecting rod of which the top and bottom outer walls are fixedly connected with multiple springs E at equal intervals, a contact ring is fixedly connected to the ends, away from the connecting rod, of every two vertically corresponding springs E, detection rods are fixedly connected to the bottom surfaces of the contact rings, a sliding groove B is formed in theposition, corresponding to the connecting rod, of the inner wall of the bottom surface of the detection seat, a sliding block B is connected to the inner wall of the sliding groove B in a sleeving mode, photoelectric sensors are fixedly mounted at the positions, corresponding to the detection rods, of the top surface of the sliding block B. Through the arrangement of the contact rings, the outerwall of the driving wheel is inspected under periodic rotation of the driving wheel, the detection effect on the outer wall of the driving wheel by one circle is guaranteed, and through the arrangement of the multiple contact rings, the outer wall of the driving wheel is inspected in an all-around mode.

Description

technical field [0001] The invention relates to the technical field of escalators, in particular to an escalator driving wheel wear detection device and a diagnosis method. Background technique [0002] The escalator drive wheel is the main structure used to drive the elevator. It is in the shape of a cylinder and the wheel hub will have a number of holes in a circular distribution. [0003] During the use of the escalator drive wheel, in order to ensure the safe operation of the escalator, it is necessary to regularly inspect the drive wheel to avoid dents or cracks under wear and tear that will affect the use. The existing detection methods mostly use naked eye observation, and the detection efficiency is low. The detection effect is not good, resulting in safety hazards that cannot be ruled out. [0004] Therefore there is an urgent need for an escalator driving wheel wear detection device and a diagnostic method to solve the above problems. Contents of the invention ...
