Description

Technical Field

[0001] This application relates to the technical field of core drilling machines, and in particular to a fixing device for core sampling. Background Technology

[0002] In the field of engineering material quality testing, core drilling is a commonly used technique to obtain information about the internal structure and properties of materials. This method is widely used in the testing of materials such as engineering rock blocks, concrete curbs, and autoclaved fly ash bricks.

[0003] One method involves on-site sampling, while the other involves the materials clerk transporting the prepared test blocks to the testing department for sampling and testing. The test blocks delivered to the testing department are placed in the sampling pool and directly below the core drilling machine, and then the core drilling machine is started to take samples.

[0004] If the test block has a regular shape, it can be placed stably directly under the core drilling machine. If the test block has an irregular shape, or if the surface of the test block is uneven due to transportation or other reasons, it cannot be placed stably directly under the core drilling machine, resulting in the defect that the test block moves during the sampling process. Utility Model Content

[0005] To ensure safety during core sampling and prevent displacement of the test block, this application provides a fixing device for core sampling.

[0006] The fixing device for core sampling provided in this application adopts the following technical solution:

[0007] A core sampling fixing device includes a worktable and a core drilling machine. The core drilling machine is fixed on the worktable, and a drive assembly is provided on the worktable. The drive assembly includes a motor, a screw, a slider, and a clamping plate. The motor is fixed on the worktable, the screw is horizontally arranged, and one end of the screw is fixedly connected to the output end of the motor. The screw is rotatably mounted on the worktable. There are two sliders and two clamping plates. The screw passes through the two sliders. The vertical sidewall of one side of the slider slides against the vertical sidewall of the worktable. The screw is threadedly connected to the sliders. The two sliders slide on the screw in a direction that moves closer or further away from each other. A connecting assembly is provided between the sliders and the clamping plates for detachable connection between the sliders and the clamping plates.

[0008] By adopting the above technical solution, the test block is placed on the worktable between two clamping plates. The motor is started, and through a screw, slider, and connecting assembly, it drives the two clamping plates to move closer together, ultimately clamping the test block. Then, the core drilling machine is started to drill and sample the test block. This improves safety during the core sampling process and prevents displacement of the test block. For different types of test blocks, especially irregularly shaped ones, different types of clamping plates can be easily replaced using the connecting assembly.

[0009] Optionally, the connecting assembly includes a main rod, a secondary rod, a sliding column, a spring, and a positioning ring. One end of the main rod is fixedly connected to the slider, and the other end is vertically inserted into one end of the secondary rod. The end of the secondary rod away from the main rod is fixedly connected to the clamping plate. The positioning ring is fixed to the outer wall of the main rod. The sliding column is a cylinder with both ends sealed and hollow inside. The sliding column is located on the outer wall of the main rod and slides in the direction close to or away from the secondary rod. The spring and the positioning ring are both located inside the sliding column. One end of the spring is fixedly connected to the positioning ring, and the other end is fixedly connected to the inner wall of the sliding column. In its natural state, the sliding column covers the joint between the main rod and the secondary rod.

[0010] By adopting the above technical solution, when encountering irregularly shaped test blocks, the corresponding clamp is selected, the sliding column is moved to expose the end of the main rod, and then the splicing of the end of the main rod and the auxiliary rod is completed by vertical insertion. The sliding column is then released to completely cover the splicing area of ​​the main rod and the auxiliary rod. Since the main rod and the auxiliary rod are spliced ​​by vertical insertion, they cannot be separated and mutually restricted in the horizontal direction. In the vertical direction, the sliding column forms a restriction, which ultimately ensures the stability of the main rod and the auxiliary rod after connection. The overall operation is convenient and quick.

[0011] Optionally, a turntable is rotatably mounted on the worktable, with the rotation axis of the turntable arranged vertically and the turntable located in the middle of the two clamping plates; a rotating assembly is provided on the worktable to drive the turntable to rotate.

[0012] By adopting the above technical solution, the test block is placed on the turntable. When it is necessary to adjust the position of the test block, the position can be adjusted by rotating the turntable.

[0013] Optionally, the rotating assembly includes an operating lever, a gear, and toothed posts. Multiple toothed posts are provided, with one end of each toothed post fixedly connected to the circumferential outer wall of the turntable and the other end horizontally cantilevered away from the turntable. Multiple toothed posts are provided, with adjacent toothed posts spaced apart along the circumferential outer wall of the turntable. The gear meshes with the nearest toothed post. One end of the operating lever is fixedly connected to the gear, and the operating lever is rotatable relative to the worktable.

[0014] By adopting the above technical solution, rotating the operating lever drives the gear to rotate, and the gear drives the turntable to rotate through the adjacent tooth column, which in turn drives the test block on the turntable to rotate, thus completing the adjustment of the test block's position.

[0015] Optionally, the operating lever is rotatably and slidably positioned relative to the worktable, and the operating lever, along with the gear, slides horizontally toward or away from the turntable, with the center point of the gear located above the turntable.

[0016] By adopting the above technical solution, the overall position of the gear is higher than that of the turntable in the vertical direction. When the position of the test block on the turntable needs to be adjusted along the length of the operating rod, the test block can be pushed by the vertical side wall of the gear by pulling the operating rod.

[0017] Optionally, a protective cover is fixed on the worktable, covering the screw and the slider. The protective cover has an elongated hole along the length of the screw, and the main rod passes through the elongated hole.

[0018] By adopting the above technical solution, the protective cover protects the screw and slider, preventing residue from falling onto the screw during core extraction and ensuring the smoothness of the threaded connection between the slider and the screw.

[0019] Optionally, a first rubber pad is fixed on the sidewalls of adjacent clamping plates that are close to each other.

[0020] By adopting the above technical solution, the first rubber pad is in direct contact with the test block, which extends the service life of the clamp.

[0021] Optionally, a second rubber pad is fixed to the vertical sidewall above the turntable of the gear.

[0022] By adopting the above technical solution, the second rubber pad is in direct contact with the test block, which extends the service life of the gear and reduces the wear on the gear when it pushes the test block.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The motor drives the two clamping plates to move closer to each other through the screw, slider and connecting assembly, and finally clamps the test block. Then the core drilling machine is started to drill the core of the test block for sampling, which improves the safety of the core drilling process and prevents the test block from shifting.

[0025] 2. For different types of test blocks, especially irregularly shaped test blocks, different types of clamps can be easily replaced through the connecting components;

[0026] 3. The rotating components and turntable allow for adjustment of the placement angle of the test block between the two clamping plates. Attached Figure Description

The core drill 11 is fixed on the workbench 1, and the drive assembly 2 is located below the core drill 11. The drive assembly 2 clamps and limits the test block placed below the core drill 11, thereby ensuring that the core drilling operation is stable and safe.

[0035] refer to Figure 1 and Figure 2 The drive assembly 2 includes a motor 21, a screw 22, a slider 23, and a clamping plate 24. The motor 21 is fixed on the worktable 1. The screw 22 is horizontally positioned, with one end fixedly connected to the output end of the motor 21. The screw 22 is rotatably mounted on the worktable 1 and rotates relative to the worktable 1. Two sliders 23 and two clamping plates 24 are provided. The screw 22 passes through both sliders 23. The vertical sidewall of one side of each slider 23 slides against the vertical sidewall of the worktable 1. The screw 22 is threadedly connected to the sliders 23, and its own thread extends symmetrically from the midpoint to both sides. The two sliders 23 slide on the screw 22 in directions that are closer or further apart. A protective cover 6 is fixed on the worktable 1, covering the screw 22 and the sliders 23. The length of the protective cover 6 is along the length of the screw 22.

[0036] refer to Figure 1 , Figure 2 and Figure 3A connecting component 3 is provided between the slider 23 and the clamping plate 24.

One end of the main rod 31 is fixedly connected to the slider 23, and the other end is vertically inserted into one end of the secondary rod 32. That is, a protrusion 321 is fixed at the end of the secondary rod 32 near the main rod 31. The protrusion 321 is L-shaped and flat. A slot 311 is opened at the end of the main rod 31 near the secondary rod 32. The protrusion 321 is inserted into the slot 311, and at this time the outer surfaces of the main rod 31 and the secondary rod 32 are flush. The end of the auxiliary rod 32 furthest from the main rod 31 is fixedly connected to the clamping plate 24. The positioning ring 34 is fixed to the outer wall of the main rod 31. The sliding column 33 is a cylindrical shape with both ends sealed and the interior hollow. The sliding column 33 is located on the outer wall of the main rod 31 and slides in the direction close to or away from the auxiliary rod 32. The spring 35 and the positioning ring 34 are both located inside the sliding column 33. One end of the spring 35 is fixedly connected to the positioning ring 34, and the other end is fixedly connected to the inner wall of the sliding column 33. The protective cover 6 has an elongated hole 61, which is opened along the length of the screw 22. The main rod 31 passes through the elongated hole 61.

[0037] refer to Figure 3 In its natural state, the sliding column 33 covers the joint between the main rod 31 and the auxiliary rod 32. When the clamping plate 24 needs to be replaced, move the sliding column 33 towards the screw 22 without releasing it until the joint between the main rod 31 and the auxiliary rod 32 is exposed. Then, lift the auxiliary rod 32 upwards to complete its removal. Next, take the new clamping plate 24 and insert the protrusion 321 into the slot 311 vertically. At this point, release the sliding column 33, and the spring 35 will push the sliding column 33 back to its original position, covering the joint between the main rod 31 and the auxiliary rod 32.

[0038] refer to Figure 1 and Figure 4Each of the two clamping plates 24 has a first rubber pad 7 fixed to its adjacent sidewall. A turntable 4 and a rotating assembly 5 are provided on the worktable 1. The turntable 4 is rotatably mounted on the worktable 1, horizontally positioned with its rotation axis vertically aligned. The turntable 4 is located at the midpoint of the line connecting the two clamping plates 24, i.e., exactly in the middle of the two clamping plates 24. The rotating assembly 5 includes an operating lever 51, toothed posts 53, and gears 52. Multiple toothed posts 53 are provided, each being a short column. One end of each toothed post 53 is fixedly connected to the circumferential outer wall of the turntable 4, while the other end is horizontally cantilevered away from the turntable 4. Multiple toothed posts 53 are provided, with adjacent toothed posts 53 spaced apart along the circumferential outer wall of the turntable 4. The operating lever 51 is horizontally positioned and the screw 22 is vertically positioned. The operating lever 51 is rotatably mounted on the worktable 1, and it is also slidably mounted on the worktable 1.

In the vertical direction, the center point of the gear 52 is located above the turntable 4, and the adjacent tooth post 53 on the turntable 4 near the gear 52 meshes with the gear 52.

[0039] refer to Figure 4 A second rubber pad 8 is fixed on the vertical side wall above the turntable 4 of gear 52.

[0040] The implementation principle of the core sampling fixing device in this embodiment is as follows: The test block is placed on the turntable 4, and the motor 21 is started. The motor 21 drives two clamping plates 24 to move closer to each other via the screw 22, slider 23, and connecting assembly 3, ultimately clamping the test block. During this process, the operating lever 51 is rotated, which drives the gear 52 to rotate. The gear 52 drives the turntable 4 to rotate via the adjacent toothed post 53, ultimately causing the test block on the turntable 4 to rotate, thus adjusting the horizontal angle position of the test block. For different types of test blocks, especially irregularly shaped test blocks, different types of clamping plates 24 can be easily replaced using the connecting assembly 3. The core drilling machine 11 is then started to drill and sample the test block, achieving improved safety during the core sampling process and preventing displacement of the test block. For different types of test blocks, especially irregularly shaped test blocks, different types of clamping plates 24 can be easily replaced using the connecting assembly 3.
