Abstract

The invention discloses an image acquisition device for detecting ballastless track roadbed slab cracks and a use method, and the image acquisition device comprises walking wheels, a support frame, a parallel convex groove slide rail frame, a pulley module, an instrument bearing device, a first mobile phone fixing support, a push rod, a second mobile phone fixing support, a first smart phone and a second smart phone. The parallel convex groove slide rail frame is arranged on the two supporting frames; walking wheels are arranged on the left side and the right side below the two supporting frames; the walking wheels are in sliding connection with the track; a pulley module is arranged on the parallel convex groove slide rail frame; the front end of the instrument bearing device is connected with the first mobile phone fixing bracket, and the rear end is connected with the push rod and fixed on the pulley module; a second mobile phone fixing bracket is arranged on one side, far away from the instrument bearing device, of the push rod to push the parallel convex groove slide rail frame to advance along the track direction; the first intelligent mobile phone is placed on the first mobile phone fixing bracket and is used for shooting a crack image of the roadbed slab; and the second smart phone is placed on the second mobile phone fixing bracket and is used for displaying the crack image shot by the first smart phone.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an image acquisition device and a use method for detecting cracks in a ballastless track bed slab. Background technique [0002] At present, my country mainly adopts manual static detection method to detect ballastless track defects, but the effective skylight time of rail transit is only 2-3 hours for line maintenance, and the line mileage of high-speed railway is long. If the existing manual measurement method is used, not only manual recording is required, the efficiency is low, and the measurement accuracy is not high. Therefore, it is necessary to find a simple, convenient and efficient image acquisition device for cracks in ballastless track slabs to meet the needs of ballastless track defect detection. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides an image acquisition device and usage metho...
