5th step opens bridge pier detection sensor 4, starts to detect bridge pier.
The device of the invention when in use, carries out in accordance with the following steps:
The upper clamping electromagnet 10209 of 6th step, upper clamping mechanism 1 is powered, the clamping iron block of upper clamping mechanism 1 10305 are attracted up, and lower part clamping body 103 moves up at this time, by the cooperation of ramp 10208 and lower inclined plane 10304, It is pushed in the upward bridge pier channel 10205 of support body 10207 so that wedge shape push top 10303 will clamp, further makes rubber layer 1020703 It is bonded bridge pier surface, is clamped in upper clamping mechanism 1 on bridge pier.This is not clamped between clamp system 1 and bridge pier at present.
The tractive magnet 303 of 7th step, traction mechanism 3 is powered, and interior iron block 30401 is attracted, when interior iron block 30401 with tractive magnet 303 contact when, outer iron block 30402 moves on interior iron block 30401 to be continued to be attracted, outer iron block The traction rope 306 connected on 30402 is driven traction, and traction rope 306 does pulling motion, and axial reset spring 305 is compressed, together When drive lower clamp system 2 to rise relative to upper clamping mechanism 1.
8th step, after the completion of traction mechanism 3 is drawn, lower clamp system 2 is made using method identical with the 6th step energization Clamp system 1 is clamped on bridge pier.
The clamping electromagnet 10209 of 9th step, upper clamping mechanism 1 powers off, and clamps support body 10207 and passes through compressed recovery Spring 10211 returns to initial position, meanwhile, lower part clamping body 103 is released, and is fallen on bottom limit ring flat-plate 107, upper clamping It is detached between mechanism 1 and bridge pier, handles undamped state.Lower disengaging process between clamp system and bridge pier is identical with this.Together When compressed axial reset spring 305 screen resilience will be pushed up on upper clamping mechanism 1, completion is once climbed along the creeping motion type of bridge pier The process of liter.
Tenth step, repeats the process of the 6th step to the 9th step, does not stop such electronic work of magnet switching, until climb to Bridge pier extreme position, no longer rises.
11st step, after detection, whole device decline.During decline, upper clamping mechanism 1, lower clamp system 2 with Clamping and disengaging mode are climbed with creeping motion type between bridge pier, and process is identical, and difference is only that lower clamp system 2 is first clamped with bridge pier, Upper clamping mechanism 1 is first detached from bridge pier, then traction mechanism 3 draw so that upper clamping mechanism 1 relative to lower clamp system 2 to Lower movement, while axial reset spring 305 is compressed, and is clamped between last upper clamping mechanism 1 and bridge pier, lower clamp system 2 with It is detached between bridge pier, the screen resilience of compressed axial direction reset spring 305 will push away under lower clamp system 2, complete once along bridge The creeping motion type of pier declines process.
12nd step repeats the process of the 11st step, does not stop the electronic work of such magnet switching, until dropping to bridge pier Bottom position, the work flow of the bridge pier detection device of electromagnetic spring type is furthermore achieved.
