Description

A device for testing the corrosion resistance of bridge steel reinforcement Technical Field

[0001] This utility model belongs to the technical field of bridge testing equipment, and specifically relates to a device for testing the corrosion resistance of bridge steel bars. Background Technology

[0002] The bridge steel reinforcement corrosion resistance testing device is mainly used to evaluate the corrosion resistance of steel reinforcement in bridges. By detecting parameters such as the degree of corrosion and corrosion rate, it provides a scientific basis for bridge maintenance, reinforcement, and repair. This device typically features high precision, high stability, and ease of operation, and can adapt to the testing needs of different bridge structures and environmental conditions. The working principle of the bridge steel reinforcement corrosion resistance testing device is based on electrochemical principles. When steel reinforcement corrodes, a potential difference and current density change occur on its surface. The detection probe senses these changes and transmits the signals to a data acquisition and processing system. The system then analyzes and processes the signals to ultimately determine parameters such as the degree of corrosion and corrosion rate of the steel reinforcement.

[0003] The announcement number "CN221725835U" discloses a device for monitoring corrosion of bridge cable steel wires. The device includes a retaining ring with an installation groove. A first retaining groove is formed on the inner wall of the installation groove. A card is slidably disposed within the first retaining groove. A retaining strip is fixedly attached to one end of the card. A second retaining groove, matching the retaining strip, is provided on the side of the first retaining groove away from the retaining strip. The retaining ring has an axially extending hole penetrating the second retaining groove. A limiting rod is inserted into the hole, with one end of the limiting rod located within the second retaining groove. A retaining block is fixedly disposed within the hole. A third retaining groove, matching the retaining block, is provided on the limiting rod. A spring is located within the third retaining groove and sleeved on the limiting rod. Both ends of the spring abut against the limiting rod and the retaining block, respectively. This device achieves complete coverage of the cable by using a retaining ring and a card. The spring and limiting rod then limit the retaining strip on the card, ensuring the stability of the card and retaining ring, preventing the retaining ring from falling off, and improving safety.

[0004] While the aforementioned utility model ensures the stability of the card and retaining ring, prevents the retaining ring from falling off, and improves safety, like other corrosion detectors on the market, it lacks an anti-detachment structure between the wire and the detector. If the wire becomes loose or falls off during movement or vibration, it will cause unstable signal transmission, introduce noise or interference, and thus affect the accuracy of the test results. Moreover, a loose wire can cause data transmission interruption, resulting in the loss or incompleteness of test data. In addition, in order to maintain the stability of the wire, the operator may need to frequently manually fix the wire, which not only increases the complexity of the operation but may also affect the testing efficiency. Summary of the Invention

[0005] In response to the problems mentioned in the background art, the purpose of this utility model is to provide a bridge steel reinforcement corrosion resistance testing device to solve the problem that there is no anti-derailment structure between the conductor and the testing instrument. If the conductor becomes loose or falls off during movement or vibration, it will lead to unstable signal transmission, introduce noise or interference, and thus affect the accuracy of the test results. Moreover, the loose conductor will cause data transmission interruption, resulting in the loss or incompleteness of test data.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A device for testing the corrosion resistance of bridge steel bars includes a testing device body. One end of the testing device body has an installation groove, and a display screen is installed inside the installation groove. A control panel is installed at one end of the testing device body. A wire is movably connected to the upper end of the testing device body. A positioning block is fixedly connected to the outer wall of the wire. Fixing components are symmetrically installed inside the positioning block. A testing probe is fixedly connected to one end of the wire, and a plug is fixedly connected to the other end of the wire. A mounting base is fixedly connected to the upper end of the testing device body, and an anti-wire-detachment component is installed inside the mounting base.

[0008] The anti-derailment assembly includes a clamping block, a threaded rod, a threaded hole, and a knob. A through groove is provided at the upper end of the mounting base, and threaded holes are symmetrically provided at both ends of the mounting base. The threaded holes communicate with the inside of the through groove, and a threaded rod is threadedly connected inside the threaded hole. One end of the threaded rod extends into the through groove and is rotatably connected to the clamping block. The clamping block and the inside of the through groove are slidably connected. The other end of the threaded rod is fixedly connected to a knob. This assembly ensures a stable connection between the wire and the detection device, avoiding errors in detection data caused by wire detachment or loosening. Furthermore, it effectively reduces interference from external factors such as wind and vibration on the wire connection, thereby ensuring the continuity and accuracy of data during the detection process.

[0009] As a preferred technical solution, the clamping end of the clamping block is glued with a protective pad. The surface of the protective pad is provided with anti-slip protrusions. The protective pad is made of soft rubber, which can play a buffering role, reduce wear on the surface of the wire, and thus extend the service life of the wire.

[0010] As a preferred technical solution, guide grooves are symmetrically opened at both ends of the through groove, and guide blocks are symmetrically fixedly connected to both ends of the clamping block. The guide blocks and guide grooves are slidably connected. The sliding cooperation between the guide blocks and guide grooves can ensure the precise position of the clamping block during movement, which helps to achieve precise clamping of the clamped object and reduce errors caused by position deviation.

[0011] As a preferred technical solution, the fixing component includes a cavity, a return spring, a movable plate, and a fixing block. The positioning block has symmetrically formed cavities inside. A return spring is fixedly connected to one end of each cavity, and a movable plate is fixedly connected to the other end of the return spring. The movable plate is slidably connected to the cavity. A fixing block is fixedly connected to the end of the movable plate away from the return spring. The fixing block extends from the side end of the positioning block away from the movable plate. Both the upper and lower ends of the fixing block are sloped. A positioning groove is formed on the upper end of the detection device body, and the positioning groove is inserted into the positioning block. Fixing grooves are symmetrically formed at both ends inside the positioning groove, and the fixing grooves are snap-fitted into the fixing block. A slot is formed at the bottom of the positioning groove, and the slot is inserted into the plug. This ensures a more secure connection between the wire and the detection device, preventing the wire from loosening or falling off, thereby ensuring the accuracy and stability of the detection data. Furthermore, it enhances the safety of the detection device, preventing wires from becoming loose, falling off, or short-circuiting, which could lead to safety accidents.

[0012] As a preferred technical solution, a baffle is movably installed inside the mounting slot, and magnetic suction slots are symmetrically opened at one end of the mounting slot. Magnetic suction blocks are symmetrically fixedly connected to one end of the baffle. The magnetic suction blocks and magnetic suction slots are magnetically connected, which can prevent dust, sand and other small particles from directly contacting the display screen, thereby reducing scratches and wear and extending the service life of the display screen.

[0013] In summary, the present invention has the following main advantages:

[0014] First, in this utility model, the wire is first connected to the detection device body, and then the knob is rotated. The knob drives the threaded rod to rotate, and the threaded rod rotates with the threaded hole, thereby controlling the threaded rod to drive the clamping block to slide inside the through groove. When the clamping block slides, it drives the guide block to slide inside the guide groove. When the clamping blocks close together, they clamp the wire and complete the fixing of the wire. This can ensure a stable connection between the wire and the detection device, avoid detection data errors caused by the wire falling off or loosening, and effectively reduce the interference of external factors on the wire connection, such as wind and vibration, thereby ensuring the continuity and accuracy of data during the detection process.

[0015] Secondly, in this utility model, the plug at one end of the guide is inserted into the slot on the main body of the detection device, and the positioning block is inserted into the positioning groove. During the insertion process, the squeezing force applies pressure to the inclined surface of the fixing block, causing the fixing block to retract into the cavity. When the fixing block moves to the fixing groove, the reset spring resets, and the fixing block pops out and engages with the fixing groove to complete the connection between the wire and the main body of the detection device. This ensures a more stable connection between the wire and the detection device, preventing the wire from loosening or falling off, thereby ensuring the accuracy and stability of the detection data. It also enhances the safety of the detection device, preventing the wire from being loose, falling off, or short-circuiting, which could lead to safety accidents. Attached Figure Description

[0022] Example

[0023] Referring to Figures 1 to 5, the bridge steel reinforcement corrosion resistance testing device of this embodiment includes a testing device body 1. One end of the testing device body 1 has an installation groove 2. A display screen 3 is installed inside the installation groove 2. A control panel 7 is installed at one end of the testing device body 1. A wire 8 is movably connected to the upper end of the testing device body 1. A positioning block 11 is fixedly connected to the outer wall of the wire 8. Fixing components 13 are symmetrically installed inside the positioning block 11. A testing probe 15 is fixedly connected to one end of the wire 8. A plug 9 is fixedly connected to the other end of the wire 8. A mounting base 16 is fixedly connected to the upper end of the testing device body 1. An anti-derailment component 18 is installed inside the mounting base 16.

[0024] The anti-derailment assembly 18 includes a clamping block 181, a threaded rod 182, a threaded hole 183, and a knob 184. A through groove 17 is provided at the upper end of the mounting base 16. Threaded holes 183 are symmetrically provided at both ends of the mounting base 16, communicating with the interior of the through groove 17. A threaded rod 182 is threadedly connected inside the threaded hole 183. One end of the threaded rod 182 extends into the through groove 17 and is rotatably connected to the clamping block 181. The clamping block 181 is slidably connected to the interior of the through groove 17. The other end of the threaded rod 182 is fixedly connected to the knob 184. The wire 8 is connected to the detection device body 1. Then, the knob 184 is rotated, causing the threaded rod 182 to rotate. The threaded rod 182 rotates threadedly with the threaded hole 183, thereby controlling the threaded rod 182 to drive the clamping block 181 to slide within the through groove 17. When the clamping block 181 closes, it clamps the wire 8, thus fixing the wire 8.

[0025] Referring to Figure 2, a protective pad 19 is glued to the clamping end of the clamping block 181. The surface of the protective pad 19 is provided with anti-slip protrusions. The protective pad 19 is made of soft rubber. The protective pad 19 can play a buffering role, reduce the wear on the surface of the wire 8, and thus extend the service life of the wire 8.

[0026] Referring to Figure 2, guide grooves 20 are symmetrically opened at both ends of the through groove 17, and guide blocks 21 are symmetrically fixedly connected at both ends of the clamping block 181. The guide blocks 21 and the guide grooves 20 are slidably connected. When the threaded rod 182 drives the clamping block 181 to slide inside the through groove 17, the clamping block 181 drives the guide block 21 to slide inside the guide groove 20.

[0027] Referring to Figure 4, the fixing component 13 includes a cavity 131, a return spring 132, a moving plate 133, and a fixing block 134. The positioning block 11 has symmetrically arranged cavities 131 inside. A return spring 132 is fixedly connected to one end of each cavity 131, and a moving plate 133 is fixedly connected to the other end of the return spring 132. The moving plate 133 is slidably connected to the cavity 131. A fixing block 134 is fixedly connected to the end of the moving plate 133 away from the return spring 132. The end of the fixing block 134 away from the moving plate 133 extends out of the side of the positioning block 11. Both the upper and lower ends of the fixing block 134 are sloped. A positioning groove 12 is formed on the upper end of the detection device body 1. The positioning groove 12 is connected to the positioning block 11. Block 11 is a plug-in connector. The positioning groove 12 has symmetrically opened fixing grooves 14 at both ends. The fixing grooves 14 and the fixing block 134 are snap-fitted together. The bottom of the positioning groove 12 has a slot 10. The slot 10 and the plug 9 are plug-in connected together. The plug 9 at one end of the guide is inserted into the slot 10 on the detection device body 1. At the same time, the positioning block 11 is inserted into the positioning groove 12. During the insertion process, the squeezing force is applied to the inclined surface of the fixing block 134, causing the fixing block 134 to retract into the cavity 131. When the fixing block 134 moves to the fixing groove 14, the return spring 132 returns to its original position, and the fixing block 134 pops out and snaps into the fixing groove 14 to complete the connection between the wire 8 and the detection device body 1.

[0028] Referring to Figure 1, a baffle 6 is movably installed inside the mounting slot 2. A magnetic suction slot 5 is symmetrically opened at one end of the mounting slot 2. A magnetic suction block 4 is symmetrically fixedly connected to one end of the baffle 6. The magnetic suction block 4 and the magnetic suction slot 5 are magnetically connected. After the bridge reinforcement inspection is completed, the baffle 6 is merged with the mounting slot 2 at one end of the inspection device body 1, so that the magnetic suction block 4 at one end of the baffle 6 is magnetically connected to the magnetic suction slot 5 inside the mounting slot 2.

[0029] Operating principle and advantages: First, insert the plug 9 at one end of the guide into the slot 10 on the main body 1 of the detection device, and at the same time insert the positioning block 11 into the positioning groove 12. During the insertion process, the squeezing force applies pressure to the inclined surface of the fixing block 134, causing the fixing block 134 to retract into the cavity 131. When the fixing block 134 moves to the fixing groove 14, the return spring 132 returns to its original position, and the fixing block 134 pops out and engages with the fixing groove 14 to complete the connection between the wire 8 and the main body 1 of the detection device. Then, rotate the knob 184, which drives the threaded rod 182 to rotate. The threaded rod 182 rotates with the threaded hole 183, thereby controlling the threaded rod 182 to drive the clamping block 181 to slide inside the through groove 17. When the clamping block 181 slides, it drives the guide block 21 to slide inside the guide groove 20. When the clamping blocks 181 close together, they clamp the wire 8, thus completing the fixation of the wire 8.

[0030] This invention can ensure a stable connection between the wire 8 and the detection device, avoid errors in detection data caused by the wire 8 falling off or becoming loose, and effectively reduce interference from external factors on the connection of the wire 8, such as wind and vibration, thereby ensuring the continuity and accuracy of data during the detection process.
