[0016] A detection method for a prefabricated bridge health detection device comprises the following steps:

[0017] S1. When it is necessary to perform a health inspection on the surface of the bridge pier, the whole crawling health inspection device is put on the bridge pier to be inspected by using the cooperation of the sub-semicircular ring and the mother semicircular ring. Then the inspector uses the cooperation of the handheld device, the controller, the motor, the sub-semicircular ring or the mother semicircular ring connected thereto, the bevel gear, the two sets of rectangular blocks, the first bearing, the two first cylindrical holes, the two bevel gears, the second bearing, the four second cylindrical holes, the four gear bodies and the two rotating rods to rotate the two anti-sliding blocks. Then, the whole crawling health inspection device starts to move from bottom to top on the bridge pier by using the cooperation of the rotating two anti-sliding blocks, the sub-semicircular ring, the mother semicircular ring, the multiple connecting blocks and the multiple auxiliary wheels. At the same time, the started camera and the controller are used to transmit the captured image of the bridge pier surface to the screen of the inspector's handheld device for viewing and judgment;

[0018] S2. When the crawling health detection device moves to the position where the detection is required, the inspector directly uses the handheld device and the controller to turn off the two motors at the same time. Then, the inspector uses the handheld device, the controller, the four electric telescopic rods and the corresponding mounting blocks to make each group of two mounting plates move toward each other. Then, by moving each group of mounting plates, the corresponding group of limit holes and the corresponding four limit rods, the corresponding group of moving plates are driven to move toward each other. Then, by moving each group of moving plates, the corresponding connecting plates and the arc blocks, the corresponding first anti-slip pads are driven to move. At the same time, by using the cooperation of each group of two mounting plates moving toward each other, the two limit blocks connected thereto and the corresponding two fixing bolts, the corresponding two elastic sheets are bent and deformed, that is, the bent and deformed elastic sheets are used to drive the second anti-slip pads connected thereto to contact the surface of the bridge pier.

[0019] S3. Then, the first anti-skid pad is used to prevent the rubber wheel of the auxiliary wheel in contact with it from rotating. Then, the rubber wheel of the auxiliary wheel that cannot rotate, the limit block, the fixing bolt, the elastic sheet and the second anti-skid pad are used to prevent the crawling health detection device from moving after it stops moving. Finally, the inspector uses the handheld device, the controller, two electric push rods, two U-shaped blocks and two hand-tightened bolts to make the detection end surfaces of the two ultrasonic probes contact the surface of the pier for detection.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention can prevent the crawling health detection device from falling from a high altitude due to insufficient anti-skid ability after it moves to the position where the detection is required by setting an auxiliary mechanism, which not only effectively improves the use effect of the prefabricated bridge health detection device, but also improves the use efficiency of the prefabricated bridge health detection device. When it is necessary to use the rubber wheels of the auxiliary wheels to provide a certain anti-skid effect for the crawling health detection device, the inspector can directly use the handheld device, the controller, the four electric telescopic rods and the corresponding mounting blocks to make each group of two mounting plates move toward each other, and then use the movement of each group of mounting plates, the corresponding group of limit holes and the corresponding four limit rods to drive the corresponding group of moving plates to move toward each other;

[0022] 2. The present invention then utilizes the cooperation of each group of moving plates, the corresponding connecting plates and the arc-shaped blocks that move toward each other to drive the corresponding first anti-skid pad to move, and at the same time utilizes the cooperation of each group of two mounting plates that move toward each other, the two limit blocks connected thereto and the corresponding two fixing bolts to enable the corresponding two elastic sheets to bend and deform, that is, utilizes the bent and deformed elastic sheet to drive the second anti-skid pad connected thereto to contact the surface of the bridge pier, and then utilizes the cooperation of the first anti-skid pad to enable the rubber wheel of the auxiliary wheel that contacts therewith to be unable to rotate, and then utilizes the cooperation of the rubber wheel of the auxiliary wheel that cannot rotate, the limit blocks, the fixing bolts, the elastic sheet and the second anti-skid pad to improve the anti-skid ability of the crawling health detection device after it stops moving;

[0023] 3. The present invention can perform health detection operations on prefabricated piers of prefabricated bridges by setting up a detection mechanism. When it is necessary to perform a health detection on the surface of the pier, the cooperation of the sub-semicircular ring and the mother semicircular ring can be used to put the entire crawling health detection device on the pier that needs to be detected. Then the inspector can use the cooperation of the handheld device and the controller to start the motor and the camera, and then use the motor, the sub-semicircular ring or the mother semicircular ring connected thereto, the bevel gear, two sets of rectangular blocks, the first bearing, two first cylindrical holes, two bevel gears, the second bearing, four second cylindrical holes, four gear bodies and two rotating rods to realize the rotation operation of the two anti-sliding blocks.

[0024] 4. The present invention then utilizes the cooperation of two rotating anti-sliding blocks, a sub-semicircular ring, a female semicircular ring, multiple connecting blocks and multiple auxiliary wheels to enable the entire crawling health detection device to start moving from bottom to top on the bridge pier. At the same time, the started camera will, with the cooperation of the controller, transmit the captured image to the screen of the inspector's handheld device for viewing and judgment. When the crawling health detection device moves to the position where inspection is required and stops, the inspector can directly use the handheld device, controller, two electric push rods, two U-shaped blocks and two hand-tightened bolts to enable the detection end surfaces of the two ultrasonic probes to contact the surface of the bridge pier for inspection.

When the crawling health inspection device completes the installation operation on the pier 1, the rubber wheel of each auxiliary wheel 213 just contacts the surface of the pier 1, and the surface of each anti-sliding block 211 also just contacts the surface of the pier 1. Then, the controller 314 is connected to the external power supply, and then the controller 314 is connected to the inspector's handheld device with a wire. When everything is ready, the inspector can use the handheld device and the controller 314 to start the two motors 203 and the two cameras 220 at the same time. At this time, each motor 203 started will drive the bevel gear 204 connected to it to rotate with the cooperation of the sub-semicircle ring 202 or the mother semicircle ring 201 connected thereto, and each rotating bevel gear 204 will directly drive the bevel gear 207 meshing with it to rotate with the cooperation of the corresponding set of rectangular blocks 205, the first bearing and the first cylindrical hole 206. At the same time, each rotating bevel gear 207 will also rotate with the cooperation of the corresponding set of rectangular blocks 205, the second bearing, the corresponding two second cylindrical holes 208 and the corresponding two gear bodies 210. When the two anti-slide blocks 211 start to rotate, the two anti-slide blocks 211 will cooperate with the sub-semicircle ring 202, the mother semicircle ring 201, the multiple connecting blocks 212 and the multiple auxiliary wheels 213 to make the entire crawling health detection device start to move from bottom to top on the bridge pier 1. At this time, the two moving cameras 220 will also shoot the surface of the bridge pier 1 during the movement, and then directly transmit the captured image data to the controller 314 in the form of electrical signals, and then transmit it to the handheld device of the detection personnel, and the screen of the handheld device will be displayed for the detection personnel to watch. Look and make a judgment. When the crawling health detection device moves to the position where detection is required, the inspector can directly use the cooperation of the handheld device and the controller 314 to turn off the two motors 203 at the same time, and then start the four electric telescopic rods 308 at the same time. At this time, each set of electric telescopic rods 308 started will drive the corresponding set of mounting plates 315 to move toward each other with the cooperation of the corresponding mounting blocks 309, and each set of moving mounting plates 315 will directly drive the corresponding set of moving plates 301 to move toward each other with the cooperation of the corresponding set of limiting holes 304 and the corresponding four limiting rods 303, and then each set of two moving plates 301 moving toward each other will directly drive the two connecting plates 305 connected to it to move.Then, each moving connecting plate 305 will also drive the arc block 306 connected thereto to move, and each moving arc block 306 will also drive the first anti-skid pad 307 connected thereto to move. At the same time, each group of two mounting plates 315 moving towards each other will also bend and deform the corresponding two elastic sheets 312 under the cooperation of the two limit blocks 310 connected thereto and the corresponding two fixing bolts 311. At this time, each bent and deformed elastic sheet 312 will drive the second anti-skid pad 313 connected thereto to move toward the direction of the bridge pier 1. When each first anti-skid pad 307 is in tight contact with the rubber wheel surface of the corresponding auxiliary wheel 213, the inspector can directly use the handheld device and the controller 314 to suspend all the electric telescopic rods 308 at the same time. At this time, the rubber wheel of each auxiliary wheel 213 is fixed under the action of the first anti-skid pad 307 in contact with it, and the surface of each second anti-skid pad 313 is just in tight contact with the surface of the pier 1, that is, the rubber wheel of the auxiliary wheel 213 that cannot rotate is used to improve the stopping speed of the crawling health detection device. The anti-skid ability of the crawling health detection device after it stops moving is further improved by the cooperation of the limit block 310, the fixing bolt 311, the elastic sheet 312 and the second anti-skid pad 313. At the same time, the two anti-slip blocks 211 that have stopped rotating can also provide a certain anti-skid ability, that is, to ensure that the crawling health detection device will not fall from a high altitude due to insufficient anti-skid ability when it moves to the position where the detection is required. When the crawling health detection device stops, the inspector can directly use the handheld device and the controller 314 At the same time, two electric push rods 215 are activated. Each electric push rod 215 will drive the U-shaped block 216 connected to it to move, and each moving U-shaped block 216 will drive the ultrasonic probe 217 connected to it to move with the cooperation of the hand-tightened bolt 218 connected to it. When the detection end surfaces of the two ultrasonic probes 217 are in contact with the surface of the pier 1, the inspector can directly use the handheld device, the controller 314 and the two ultrasonic probes 217 to detect whether the internal structure of the pier 1 is complete.
