In practical application, because the track slabs of different specifications have different thicknesses, the reinforcement cage 3 in the track slab may have a multilayer structure, that is, the reinforcement cage 3 includes a plurality of layers of reinforcements, and each layer of reinforcement includes a plurality of transverse reinforcements and longitudinal reinforcements.

Referring to fig. 1, a schematic structural diagram of the equipment for detecting insulation of the track slab steel reinforcement cage according to the present application is shown. By figure 1 can know, the application provides an insulating nature check out test set of track board steel reinforcement cage includes: the device comprises a frame 1, a mould transport vehicle 2, a position adjusting device 4 and a detecting device 5. Wherein, the frame 1 is a portal frame structure. The frame 1 may comprise a plurality of uprights and a plurality of cross-members. For example, the frame 1 includes six columns, and adjacent columns are connected by a cross beam.

And the frame 1 of the portal frame structure is arranged above the die conveying line in a crossing manner. The mould containing the reinforcement cage 3 inside is transported to the lower part of the frame 1 by the mould transport vehicle 2 according to the mould transport line. In the technical scheme that this application provided, mould transport vechicle 2 can be the flatbed, and 2 tops of mould transport vechicle are used for placing the mould, and mould transport vechicle 2's action mode can be wheeled structure, also can be track structure to adapt to different forms's production site. In practical application, after the steel reinforcement cage 3 is placed into a mold, the mold transport cart 2 can be driven to the lower part of the rack 1, so that insulation detection can be carried out on each connection point in the steel reinforcement cage 3 through the detection device 5.

In order to implement insulation detection on a plurality of connection points on the steel reinforcement cage 3, the track slab steel reinforcement cage insulation detection equipment further comprises a position adjusting device 4 arranged on the rack 1 and a detection device 5 connected to the bottom of the position adjusting device 4.
