Utility Model Content

[0004] To address the issue that the aforementioned device requires several fastening screws for laser emitter installation, making disassembly and assembly cumbersome, time-consuming, and labor-intensive due to the need for specialized tools, this invention provides an auxiliary device for testing concrete strength using the ultrasonic rebound combined method.

[0005] This utility model provides an auxiliary device for testing the strength of concrete using a combined ultrasonic rebound method, employing the following technical solution:

[0006] An auxiliary device for testing the strength of concrete using the ultrasonic rebound method includes an auxiliary mounting plate. Ultrasonic transducer positioning holes are provided at the four corners and the center of the top of the auxiliary mounting plate. A verticality scale is installed at the front end of the top of the auxiliary mounting plate, and a verticality scale positioning structure is provided between the verticality scale and the auxiliary mounting plate. Laser emitters are installed at the rear end and right side of the top of the auxiliary mounting plate, and laser emitter fixing structures are provided between the two sets of laser emitters and the auxiliary mounting plate.

[0007] The laser emitter fixing structure includes two sets of frames, which are respectively installed on the top of the auxiliary mounting plate near the laser emitter. The top of each set of frames is provided with a laser emitter clamping component, and the sides of each set of frames are provided with laser emitter clamping components.

[0008] By adopting the above technical solution, the verticality scale is installed on the top of the auxiliary mounting plate through the verticality scale positioning structure, the laser emitter is clamped and initially fixed on both sides by the laser emitter clamping component, and the top of the laser emitter is pressed and fixed again by the laser emitter pressing component. This makes the disassembly and assembly of the laser emitter and the verticality scale more convenient and improves the practicality of the device.

[0009] Optionally, the laser emitter clamping component includes a threaded post, which is screwed to the middle of the top of the frame. A rotating wheel is fixed to the top of the threaded post, and a pressure plate is rotatably connected to the bottom of the threaded post. Guide rods are connected to both ends of the top of the pressure plate, and the tops of the guide rods extend out of the frame. Guide holes matching the guide rods are opened on the surface of the frame.

[0010] By adopting the above technical solution, the staff rotates the wheel, which drives the threaded column to rotate. Since the threaded column is rotatably connected to the pressure plate, and the pressure plate is slidably connected to the frame through the guide rod, the pressure plate can be limited. When the threaded column rotates, it can drive the pressure plate to move downward to press and fix the laser emitter.

[0011] Optionally, a first soft pad is connected to the bottom of the pressure plate.

[0012] By adopting the above technical solution, the first soft pad directly contacts the laser emitter, increasing the friction between the pressure plate and the laser emitter, thereby making the laser emitter more firmly pressed.

[0013] Optionally, the laser emitter clamping component includes two sets of movable rods, which are respectively inserted on both sides of the frame. A clamping plate is installed on the side of each set of movable rods near the center of the frame. A return spring is sleeved on the outer side of each set of movable rods, and the return spring is located between the clamping plate and the frame. A baffle is installed on the end of each set of movable rods away from the clamping plate.

[0014] By adopting the above technical solution, the clamping plate can be pushed against both sides of the laser emitter under the elastic force of the return spring, thereby clamping the laser emitter.

[0015] Optionally, a second soft pad is connected to one end of each of the two sets of clamps that are close to each other.

[0016] By adopting the above technical solution, the second soft pad directly contacts the laser emitter, increasing the friction between the clamp and the laser emitter, thereby making the laser emitter more securely clamped.

[0017] Optionally, the verticality scale positioning structure includes four sets of grooves. The four sets of grooves are respectively opened at the top of the auxiliary mounting plate near one end of the verticality scale. A mounting cylinder is installed inside each of the four sets of grooves. The top of each of the four sets of mounting cylinders extends out of the groove. A sliding plate is slidably installed inside each of the four sets of mounting cylinders. A moving rod is connected to the top of each of the four sets of sliding plates. A positioning spring is sleeved on the outside of each of the four sets of moving rods. The positioning spring is located between the top of the sliding plate and the inner top wall of the mounting cylinder. The top of each of the four sets of moving rods extends out of the mounting cylinder and is fitted with a positioning plate.

[0018] By adopting the above technical solution, the positioning plate is pulled to move, and the positioning plate drives the sliding plate to move through the moving rod and compresses the positioning spring. Then, the verticality scale is placed between the four sets of mounting cylinders and the positioning plate is released. Under the elastic force of the positioning spring, the four sets of positioning plates move downward and press on the top of the verticality scale, which facilitates the disassembly and assembly of the verticality scale.

[0019] Optionally, each of the four sets of positioning plates has a rubber pad attached to one end near the verticality scale, and the tops of the two sets of positioning plates on the left and the two sets on the right are each attached with a handle.

[0020] By adopting the above technical solution, the friction between the positioning plate and the verticality scale is increased through direct contact between the rubber pad and the verticality scale, making the verticality scale more stable during installation. At the same time, the handle makes it convenient for workers to hold the handle and pull the positioning plate to move.

[0021] In summary, this utility model has at least one of the following beneficial effects:

[0022] By using the frame, laser emitter clamping parts, and laser emitter holding parts in combination, the laser emitter holding parts clamp the two sides of the laser emitter, and the laser emitter clamping parts press down on the top of the laser emitter, making the assembly and disassembly of the laser emitter quicker and easier. The laser emitter can be fixedly installed on the top of the auxiliary mounting plate without the need for screws.

[0023] The perpendicularity gauge can be disassembled and assembled by moving the positions of the four sets of positioning plates through the coordinated arrangement of grooves, sliding plates, positioning springs, mounting cylinders, moving rods, and positioning plates. There is no need to use glue to bond the perpendicularity gauge and the auxiliary mounting plate, thus avoiding damage to the auxiliary mounting plate caused by the stickiness of the glue when disassembling the perpendicularity gauge.

[0029] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0030] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2This utility model provides an embodiment of an auxiliary device for testing the ultrasonic rebound method of concrete strength, comprising an auxiliary mounting plate 1. Ultrasonic transducer positioning holes 2 are provided at the four corners and the center of the top of the auxiliary mounting plate 1. A verticality scale 5 is installed at the front end of the top of the auxiliary mounting plate 1. A verticality scale positioning structure 6 is provided between the verticality scale 5 and the auxiliary mounting plate 1. The verticality scale positioning structure 6 includes four sets of grooves 601, which are respectively formed on the top of the auxiliary mounting plate 1 near the verticality scale 5. At one end, an installation cylinder 604 is fixedly installed inside each of the four sets of grooves 601. The top of each of the four sets of installation cylinders 604 extends out of the grooves 601. A sliding plate 602 is slidably installed inside each of the four sets of installation cylinders 604. A moving rod 605 is fixedly connected to the top of each of the four sets of sliding plates 602. A positioning spring 603 is sleeved on the outside of each of the four sets of moving rods 605. The positioning spring 603 is located between the top of the sliding plate 602 and the inner top wall of the installation cylinder 604. The top of each of the four sets of moving rods 605 extends out of the installation cylinder 604 and is equipped with a positioning plate 606. Pull the positioning plate 606 to move it. The positioning plate 606 drives the sliding plate 602 to move through the moving rod 605 and compresses the positioning spring 603. Then, place the verticality scale 5 between the four sets of mounting cylinders 604 and release the positioning plate 606. Under the elastic force of the positioning spring 603, the four sets of positioning plates 606 move downward and press on the top of the verticality scale 5, which facilitates the disassembly and assembly of the verticality scale 5.

[0031] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 Each of the four positioning plates 606 has a rubber pad 6061 fixedly connected to one end near the perpendicularity scale 5. A handle 7 is fixedly connected to the top of the two left-hand and two right-hand positioning plates 606. The direct contact between the rubber pad 6061 and the perpendicularity scale 5 increases the friction between the positioning plate 606 and the perpendicularity scale 5, making the perpendicularity scale 5 more stable during installation. Simultaneously, the handles 7 facilitate movement of the positioning plates 606 by the operator.

[0032] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 3Laser emitters 3 are installed at the rear end and right side of the top of the auxiliary mounting plate 1. A laser emitter fixing structure 4 is provided between the two sets of laser emitters 3 and the auxiliary mounting plate 1. The laser emitter fixing structure 4 includes two sets of frames 401, which are respectively fixedly installed on the top of the auxiliary mounting plate 1 near the laser emitters 3. Each set of frames 401 has a laser emitter clamping component 402 at its top. The laser emitter clamping component 402 includes a threaded post 4023, which is screwed to the middle of the top of the frame 401. A rotating wheel 4022 is fixed to the top of the threaded post 4023, and a pressure plate 4025 is rotatably connected to the bottom of the threaded post 4023. Guide rods 4024 are fixedly connected to both ends of the top of the pressure plate 4025, and the tops of the guide rods 4024 extend out of the frame 401. Guide holes 4021 matching the guide rods 4024 are opened on the surface of the frame 401. The operator rotates the rotating wheel 4022, which in turn drives the threaded column 4023 to rotate. Since the threaded column 4023 is rotatably connected to the pressure plate 4025, and the pressure plate 4025 is slidably connected to the frame 401 via the guide rod 4024, the pressure plate 4025 can be limited. When the threaded column 4023 rotates, it drives the pressure plate 4025 to move downwards, pressing and fixing the laser emitter 3. A first soft pad 40251 is connected to the bottom of the pressure plate 4025. The first soft pad 40251 directly contacts the laser emitter 3, increasing the friction between the pressure plate 4025 and the laser emitter 3, thus making the laser emitter 3 more securely pressed.

[0033] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 3 Both sides of the two sets of frame bodies 401 are provided with laser emitter clamping components 403. Each laser emitter clamping component 403 includes two sets of movable rods 4033, which slide through both sides of the frame body 401. A clamping plate 4031 is fixedly installed on the side of each set of movable rods 4033 closest to the center of the frame body 401. A return spring 4032 is sleeved on the outer side of each set of movable rods 4033, located between the clamping plate 4031 and the frame body 401. A baffle 4034 is fixedly installed on the end of each set of movable rods 4033 away from the clamping plate 4031. Under the elastic force of the return spring 4032, the clamping plate 4031 can be pushed to abut against both sides of the laser emitter 3, thereby clamping the laser emitter 3. A second soft pad 40311 is fixedly connected to the end of each set of clamping plates 4031 closest to each other. The second soft pad 40311 is in direct contact with the laser emitter 3, which increases the friction between the clamping plate 4031 and the laser emitter 3, thereby making the laser emitter 3 more securely clamped.

[0034] Working principle: When in use, the operator pulls the two sets of handles 7. When the two sets of handles 7 move, they drive the four sets of positioning plates 606 to move upward. When the positioning plates 606 move upward, they drive the sliding plate 602 to move upward through the moving rod 605 and squeeze the positioning spring 603. At this time, the verticality scale 5 is placed between the four sets of mounting cylinders 604. Then, the handles 7 are released. Under the elastic force of the positioning spring 603, the four sets of positioning plates 606 move downward and press on the top of the verticality scale 5, so that the verticality scale 5 can be quickly installed on the top of the auxiliary mounting plate 1.

[0035] Next, the staff pulled the two sets of baffles 4034 to move. When the baffles 4034 moved, they moved the clamping plate 4031 through the movable rod 4033 and squeezed the reset spring 4032. Then, the laser emitter 3 was placed between the two sets of clamping plates 4031 and the baffles 4034 were released. Under the elastic force of the reset spring 4032, the two sets of clamping plates 4031 clamped the laser emitter 3 and initially fixed it.

[0036] Then, the staff rotates the rotating wheel 4022. When the rotating wheel 4022 rotates, it drives the threaded column 4023 to rotate. Since the threaded column 4023 is rotatably connected to the pressure plate 4025, and the pressure plate 4025 is slidably connected to the frame 401 through the guide rod 4024, the pressure plate 4025 can be limited. When the threaded column 4023 rotates, it can drive the pressure plate 4025 to move downward, and then the laser emitter 3 can be pressed and fixed again by the pressure plate 4025, so as to facilitate the quick installation of the two sets of laser emitters 3.

[0037] During testing, a horizontal line is marked on the bottom or side of the test object using a steel ruler and a marker. A certain distance from this horizontal line, the auxiliary mounting plate 1 is placed perpendicularly to the marked horizontal line on two opposite test surfaces. Two sets of laser emitters 3 are turned on, causing the laser beams to converge at the marked horizontal line. The auxiliary mounting plate 1 is slightly adjusted to center the ultrasonic transducer positioning hole 2. When the ultrasonic transducer positioning hole 2 is centered at the "0" mark and the laser beams emitted by the laser emitters 3 intersect the horizontal line, the outer contour of the auxiliary mounting plate 1 and the position of the laser emitter fixing structure 4 are marked with a marker. These marks indicate the test area and test point locations for the ultrasonic rebound method for concrete strength. This method has low requirements for operating conditions, high measurement accuracy, reduces the labor intensity of testing personnel, and is safe and reliable.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
