Description

Technical Field

[0001] This utility model relates to the field of rebound hammer installation technology, and specifically to a rebound hammer installation auxiliary device. Background Technology

[0002] As an instrument widely used in the field of construction engineering quality testing, the rebound hammer is mainly used for on-site non-destructive testing of the surface hardness of materials such as concrete and masonry, and indirectly estimates their compressive strength. At present, in the rebound test of structural components such as walls and columns, operators generally use handheld rebound hammers for measurement. However, this traditional manual handheld operation method often has the problems of high labor intensity and low efficiency, and is often inconvenient when measuring at heights.

[0003] A method has emerged that uses robotic arms to inspect walls. This involves mounting a rebound hammer on the robotic arm, which automatically inspects the wall surface, reducing the labor intensity of workers and improving efficiency. However, this method also has some drawbacks. Since rebound hammers come in different models and have different dimensions, incompatibility issues often arise when different rebound hammers are installed on the same machine. This requires adjusting the gripper of the robotic arm, which affects efficiency. Therefore, a device is needed to solve these problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figures 1 to 6 This utility model provides a technical solution: a rebound hammer installation auxiliary device, including a housing 1 and a rebound hammer body 8. A mounting plate 2 is fixedly connected to the back of the housing 1, and a connecting frame 3 is fixedly connected to the back of the mounting plate 2. The housing 1 is connected to the robotic arm through the connecting frame 3.

[0018] A fixing plate 4 is fixedly connected to the bottom of the front side of the housing 1. The fixing plate 4 is V-shaped. A vertical guide groove 5 is provided on the front side of the housing 1. A movable frame 6 is slidably connected inside the guide groove 5. A replacement seat 7 is connected to the lower surface of the movable frame 6 through a snap-fit ​​mechanism. The replacement seat 7 and the fixing plate 4 are located on the upper and lower sides of the rebounder body 8, respectively, to clamp and fix the rebounder body 8.

[0019] The connecting frame 3 can be connected to the operating end of the robotic arm, thereby fixing the housing 1 to the end of the robotic arm. The movement of the robotic arm drives the movement of the housing 1. The bottom of the movable frame 6 is connected to the replacement seat 7 through a snap-fit ​​mechanism. The bottom of the replacement seat 7 is arc-shaped, and the replacement seat 7 is available in various sizes. The size of the replacement seat 7 can be adjusted according to the size of the rebounder body 8 that needs to be fixed. The movable frame 6 can move up and down inside the guide groove 5. When the movable frame 6 moves down, it will drive the replacement seat 7 at one end to move down. The arc-shaped and V-shaped fixing plate 4 below the replacement seat 7 can position the rebounder body 8 and prevent rebound. When the main body 8 of the instrument shakes, rubber pads are provided on the bottom of the replacement seat 7 and the surface of the fixing plate 4. These pads increase the friction with the main body 8 of the rebound hammer and provide cushioning to prevent excessive pressure from damaging the rebound hammer. During measurement, the rebound hammer can record the measured data internally. At the same time, this device is installed on a robotic arm. The detection position of the rebound hammer can be determined by the movement of the robotic arm. By combining the position data recorded by the robotic arm and the numerical data of the rebound hammer, the data of an entire wall can be detected. In subsequent inspections, the position of the robotic arm and the reading of the rebound hammer can be checked to determine whether the concrete at the current position is qualified.

[0020] In this embodiment, as a preferred solution, a drive chamber 9 is provided inside the housing 1. The drive chamber 9 is provided with a drive mechanism to drive the movable frame 6 to rise and fall. The drive mechanism includes a drive motor 10 and a threaded rod 11. The drive motor 10 is fixedly connected to the inner wall of the housing 1. One end of the threaded rod 11 is rotatably connected to the inner wall of the drive chamber 9. The other end of the threaded rod 11 is fixedly connected to the output end of the drive motor 10, so that the drive motor 10 drives the threaded rod 11 to rotate. The threaded rod 11 passes through the end of the movable frame 6 away from the replacement seat 7 and is threadedly connected to the movable frame 6.

[0021] The drive motor 10 drives the threaded rod 11 at the output end to rotate. The threaded rod 11 is threadedly connected to one end of the movable frame 6. At the same time, the guide groove 5 restricts the movement direction of the movable frame 6. When the threaded rod 11 rotates, it will drive the movable frame 6 to move up and down, so that the replacement seat 7 at one end of the movable frame 6 clamps and fixes the rebound spring. The drive motor 10 can rotate in the opposite direction to lift the movable frame 6, thereby removing the main body 8 of the rebound spring.

[0022] In this embodiment, as a preferred solution, the snap-fit ​​mechanism includes a T-slot 12 and a T-block 13. The T-slot 12 is formed on the lower surface of the movable frame 6, and the T-block 13 is fixedly connected to the upper surface of the replacement seat 7. The T-block 13 is sized to match the T-slot 12 and can be detachably connected. A fixing bolt 14 is connected through the upper surface of the movable frame 6, and the lower surface of the fixing bolt 14 is threadedly connected to the inner wall of the T-block 13.

[0023] The T-shaped block 13 on the replacement seat 7 can be inserted into the T-shaped groove 12 from one side, thereby fixing the replacement seat 7 to one end of the movable frame 6. At this time, the threaded hole on the replacement seat 7 will be aligned with the through hole at one end of the movable frame 6. After the fixing bolt 14 is inserted into the through hole and threadedly connected to the threaded hole, the T-shaped block 13 can be fixed in the T-shaped groove 12, thereby fixing the position of the replacement seat 7 to prevent the replacement seat 7 from accidentally falling off during use.

[0024] In this embodiment, as a preferred solution, the drive chamber 9 is provided with an auxiliary mechanism to improve the smoothness of the movement of the movable frame 6. The auxiliary mechanism includes a guide rod 15 and an extension rod 16. The guide rod 15 is fixedly connected to the inside of the drive chamber 9, and the extension rod 16 is fixedly connected to one side of the movable frame 6. One side of the extension rod 16 is in contact with the guide rod 15 to reduce the shaking of the movable frame 6. A guide wheel 17 is rotatably connected to one end of the extension rod 16 near the guide rod 15. The outer surface of the guide wheel 17 is provided with an arc that matches the diameter of the guide rod 15, so that the guide wheel 17 is in contact with the outer surface of the guide rod 15 to reduce the friction between the extension rod 16 and the guide rod 15.

[0025] As the movable frame 6 moves up and down, it will drive the extension rods 16 on both sides to move together. The guide wheel 17 is set at the far end of the extension rod 16. The outer wall of the guide wheel 17 is an arc-shaped surface, which allows the guide wheel 17 to fit better with the guide rod 15. During the up and down movement of the movable frame 6 and the extension rod 16, the guide wheel 17 will always fit with the guide rod 15, reducing friction and limiting the shaking of the extension rod 16, further improving the stability during the clamping process of the rebound spring body 8.

[0026] In this invention, the working steps of the device are as follows: 1. Fix the connecting frame 3 to the operating end of the robotic arm. After fixing them together, select a replacement seat 7 of appropriate size according to the size of the rebound spring. Slide the T-block 13 on the replacement seat 7 into the T-slot 12 and use the fixing bolts 14 to fix the replacement seat 7 to the movable frame 6. 2. After fixing, place the rebound hammer body 8 at the lowest point of the V-shape above the fixing plate 4, start the drive motor 10, and drive the movable frame 6 to move down. Fix the position of the rebound hammer body 8 by replacing the seat 7. After fixing, the robotic arm can be used to measure the position to be measured. 3. After the measurement is completed, start the drive motor 10 to make the drive motor 10 rotate in the opposite direction to release the rebound hammer body 8. After releasing, remove the rebound hammer body 8 and store it.
