Description

Technical Field

[0001] This invention belongs to the field of bridge inspection technology, specifically referring to a bridge pier surface inspection device. Background Technology

[0002] Bridge piers are substructures that support the bridge span and transfer dead loads and vehicle live loads to the foundation. Abutments are located on both sides of the bridge, while piers are located between the abutments. The function of piers is to support the bridge span structure. During use, piers may be damaged due to natural weathering, substandard construction quality, or illegal overloading of vehicles. Therefore, in order to ensure people's safety, bridges need to be inspected regularly, including pier inspections. Currently, the equipment for detecting surface cracks on piers mainly uses manual telescopes or high-powered telescopes to observe the bridge from a distance. Due to the distance from the target, it is not easy to detect defects such as cracks in the piers, and the defects are not easy to accurately locate and describe. There are also blind spots in the inspection, resulting in a huge workload for the inspection personnel. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a bridge pier surface inspection device that can more comprehensively inspect the bridge pier surface and mark abnormal parts for easy observation and subsequent maintenance.

[0004] The technical solution adopted by the present invention is as follows: The present invention provides a bridge pier surface inspection device, including a base frame, a positioning mechanism and an inspection mechanism. The base frame includes a square frame, one side of which is a hinge plate. The hinge plate is hinged to the square frame. The side wall of the square frame and the end of the hinge plate are provided with fixing screw holes. Fixing bolts are provided in the fixing screw holes. The bottom wall of the four sides of the square frame is provided with a sliding groove. The inspection mechanism is slidably disposed in the sliding groove. The positioning mechanism is disposed above the four corners of the square frame.

[0005] Furthermore, an electric screw is rotatably installed inside the slide groove, and support rods are provided at the top of the four corners of the square frame.

[0006] Furthermore, the positioning mechanism includes a base, a second electric screw, a first slider, a first screw hole, an extension rod, a support block, a first elastic telescopic rod, a U-shaped bracket, and rollers. The base is located on top of the support rod, and a second sliding groove is formed on the top of the base. The second electric screw is rotatably disposed within the second sliding groove, and the first slider is slidably disposed within the second sliding groove, with the first slider fitting against the inner wall of the second sliding groove. The first screw hole is formed on the first slider and is threadedly engaged with the second electric screw. The extension rod is located on top of the first slider, and the support block is located on top of the extension rod. The first elastic telescopic rod is located on the side wall of the support block, and the U-shaped bracket is located at the end of the first elastic telescopic rod away from the support block. The rollers are rotatably disposed inside the U-shaped bracket.

[0007] Furthermore, the roller is made of rubber material with a certain degree of elasticity and high friction, the circumferential sidewall of the roller is concave, and the roller is an electric roller.

[0008] Furthermore, the testing mechanism includes a storage compartment containing paint. A second slider is located on the top of the storage compartment, and a second screw hole is formed on the second slider. The second slider fits against the inner wall of a sliding groove. The second screw hole engages with an electric screw. Trigger buttons are symmetrically located on both sides of the second slider, and the trigger buttons are signal-connected to the electric screw. An elastic telescopic rod is located on the side wall of the storage compartment. A base plate is hinged to the end of the elastic telescopic rod away from the storage compartment. The hinge point between the elastic telescopic rod and the base plate is located in the middle of the base plate. An extension plate is located on the side of the base plate away from the elastic telescopic rod. A spray nozzle is located at the top of the extension plate away from the base plate, and a testing plate is rotatably mounted on the outside of the spray nozzle.

[0009] Furthermore, the detection plate includes a trigger cylinder, a side plate, and a caster wheel. The trigger cylinder is rotatably located on the outside of the spray nozzle, and the side plates are symmetrically located on both sides of the trigger cylinder. The caster wheel is provided on the side of the side plate away from the base plate.

[0010] Furthermore, a discharge trough is provided on the side wall of the spray cylinder away from the base plate, and a baffle is provided in the middle of the discharge trough. A nozzle is provided on the side wall of the trigger cylinder away from the base plate, and the height of the nozzle is connected to the discharge trough. The height of the discharge trough is the same as the height of the nozzle.

[0011] Furthermore, a spring is provided between the base plate and the side plate, the spring being used to keep the detection plate in a neutral position.

[0014] The beneficial effects of the present invention using the above structure are as follows: The bridge pier surface inspection device provided by this solution, when inspecting a cylindrical bridge pier, places a foundation frame around the outside of the pier at its bottom. The positioning mechanism can retract inward according to the pier size, centering the foundation frame. Rollers allow the device to rise upward. Then, the positions of the limiting sleeves on both sides of the inspection mechanism are adjusted according to the pier size, thereby adjusting the sliding range of the inspection mechanism. This initiates the electric screw to begin inspection. Driven by the electric screw, the inspection mechanism slides along the slide groove. Upon contact with the limiting sleeve, a button is triggered to control the electric screw to reverse, causing the inspection mechanism to reciprocate cyclically as it is driven upward by the positioning mechanism, thus allowing the inspection plate to... The device reciprocates along the sidewall of the bridge pier. During inspection, if the pier surface is flat and undamaged, the universal wheels at both ends of the inspection plate adhere to the sidewall of the pier under the compression of the elastic telescopic rod and spring, and the inspection plate remains centered. When the pier is damaged, the universal wheels passing through uneven areas such as cracks are affected by external forces, causing the inspection plate to be in a non-neutral position. This causes the nozzle and baffle to misalign, and paint is sprayed from the nozzle to mark the area near the crack. This method can effectively and comprehensively inspect bridge piers and automatically mark damaged areas. Compared with traditional inspection methods, it is more comprehensive and makes the damaged areas more intuitive, facilitating subsequent maintenance of the bridge pier. Attached Figure Description

[0029] The roller 209 is made of rubber material with a certain degree of elasticity and high friction. The circumferential side wall of the roller 209 is concave. The roller 209 is an electric wheel.

[0030] The testing mechanism 3 includes a storage compartment 304 containing paint. A second slider 301 is located on the top of the storage compartment 304, with a second screw hole 302 on the slider 301. The slider 301 fits against the inner wall of a first groove 103. The second screw hole 302 engages with an electric screw 104. Trigger buttons 303 are symmetrically located on both sides of the slider 301, and are signal-connected to the electric screw 104. An elastic telescopic rod 306 is located on the side wall of the storage compartment 304.

The hinge point between the elastic telescopic rod 306 and the base plate 307 is located in the middle of the base plate 307. An extension plate 308 is located on the side of the base plate 307 away from the elastic telescopic rod 306. A spray nozzle 309 is located at the top of the end of the extension plate 308 away from the base plate 307. A testing plate 32 is rotatably mounted on the outside of the spray nozzle 309.

[0031] The detection plate 32 includes a trigger cylinder 321, a side plate 323 and a caster wheel 324. The trigger cylinder 321 is rotatably located outside the spray nozzle 309. The side plate 323 is symmetrically located on both sides of the trigger cylinder 321. The caster wheel 324 is provided on the side of the side plate 323 away from the base plate 307.

[0032] The side wall of the spray cylinder 309 away from the base plate 307 has a discharge groove 310, and a baffle 311 is provided in the middle of the discharge groove 310. The side wall of the trigger cylinder 321 away from the base plate 307 has a nozzle 322, and the height of the nozzle 322 is connected to the discharge groove 310.

[0035] A limiting sleeve 4 is fitted on the electric screw 104, and the limiting sleeve 4 is symmetrically arranged on both sides of the detection mechanism 3.

[0036] In practical use, when inspecting cylindrical bridge piers, first unscrew the fixing bolts 106, place the foundation frame 1 on the outside of the pier at the bottom, then close the hinge plate 102 and screw the fixing bolts 106 into the fixing screw holes 105 for fixation. Then, control the electric screw 202 to rotate synchronously, causing the rollers 209 to converge inwards. The rollers 209 retract inwards according to the pier size, centering the foundation frame 1. During use, the electric rollers 209 cause the device to rise. Since the inspection mechanism 3 has four sets, each set needs to inspect one-quarter of the pier's outer wall. Adjust the position of the limiting sleeves 4 on both sides of the inspection mechanism 3 according to the pier size, thereby adjusting the sliding range of the inspection mechanism 3 and preventing repeated inspections. After adjustment, start the electric screw 104 to begin inspection. Driven by the electric screw 104, the inspection mechanism 3 slides along the slide groove 103 and... After contacting the limit sleeve 4, the trigger button 303 controls the electric screw 104 to reverse. The detection mechanism 3 reciprocates during the upward movement driven by the positioning mechanism 2. The elastic telescopic rod 306 makes the base plate 307 and the detection plate 32 fit against the pier surface and are tangential to the pier surface. The detection plate 32 reciprocates against the side wall of the pier. During the detection process, if the pier surface is flat and undamaged, under the compression of the elastic telescopic rod 306 and the spring 312, the universal wheels 324 at both ends of the detection plate 32 fit against the side wall of the pier and the detection plate 32 is centered. When the pier is damaged, when passing through uneven areas such as cracks, the universal wheels 324 passing through the damaged area will be impacted by external force, causing the detection plate 32 to be in a non-neutral position for a short time. As a result, the nozzle 322 and the baffle 311 are misaligned, and the paint is sprayed out from the nozzle 322 to mark the area near the crack.
