Description

Technical Field

[0001] This utility model relates to the technical field of wall sampling equipment for building engineering, and in particular to a wall sampling device for quality testing of building engineering. Background Technology

[0002] In building construction quality inspection, wall sampling is a crucial step in assessing the performance of wall materials and structural quality. Traditional wall sampling methods face numerous challenges.

[0003] From the perspective of sampling stability and efficiency, previous devices struggled to ensure sampling stability when sampling walls. For example, some simple devices lacked effective support and guiding structures, causing the sampling drill bit to wobble during drilling, leading to sampling position deviations. This not only affected sample quality but also potentially required multiple sampling attempts, significantly reducing work efficiency. Furthermore, manual control of the drill bit feed made it difficult to precisely control drilling speed and depth, easily damaging the wall or failing to obtain suitable samples due to improper operation.

[0004] Traditional sampling drill bit replacement systems are not well-designed. Replacing a drill bit often requires multiple complex tools and involves time-consuming, tedious disassembly and installation. This not only increases the workload of operators but also prolongs equipment downtime, negatively impacting the overall project schedule, especially in construction projects with tight deadlines. Furthermore, traditional sampling drill bits are typically designed as a whole and require complete replacement. However, the primary reason for a drill bit becoming unusable due to wear is usually excessive wear at the tip. Directly replacing the entire bit increases costs and wastes resources.

[0005] Traditional methods for retrieving samples after sampling are relatively inefficient. Samples often become tightly stuck inside the sampling drill bit after sampling, requiring operators to expend considerable effort to manually remove them by tapping or squeezing. This method not only easily damages the sample, affecting the accuracy of subsequent test results, but also is time-consuming, further reducing work efficiency.

[0006] Therefore, this utility model proposes a wall sampling device for building engineering quality testing to solve the above problems.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] Reference Figure 1-10 A wall sampling device for quality inspection of building engineering includes a support frame 1, a feeding component, a drive motor 2, an mounting cylinder 3, and a sampling drill bit 4. The drive motor 2 is fixedly mounted on the support frame 1, and the mounting cylinder 3 is fixedly mounted on the output shaft of the drive motor 2. The output shaft of the drive motor 2 is hollow and connected to the mounting cylinder 3. A slider 12 is fixedly mounted on the bottom side of the support frame 1. A guide frame 11 is slidably mounted on the slider 12. A screw 13 threadedly connected to the slider 12 is rotatably mounted on the guide frame 11. One end of the screw 13 extends out of the guide frame 11 and is fixedly fitted with a handwheel to facilitate control of the drilling speed and depth of the sampling drill bit 4 in the wall.

[0036] The sampling drill bit 4 is snapped onto the mounting cylinder 3. Three arc-shaped grooves are formed on the inner wall of the mounting cylinder 3. Each of the three arc-shaped grooves contains a limit hole, a circular groove, and a convex hole. Multiple limit holes penetrate the sampling drill bit 4. Arc-shaped blocks 41 are movably snapped onto each of the three arc-shaped grooves.

Limit pins 43 are inserted into corresponding limit holes, and the end of springs 42 furthest from the arc-shaped blocks 41 is fixed. Installed on the inner wall of the corresponding circular groove, the convex column 44 is slidably installed in the corresponding convex hole, so that when the convex column 44 is pressed in the direction of the axis of the mounting cylinder 3, the arc block 41 is controlled to drive the limit pin 43 to disengage from the limit hole, and the spring 42 is stretched at the same time.

Each of the three mounting shells 53 has a roller 531 rotatably installed inside. Each of the three rollers 531 is parallel to the axis of the support ring 5, which can provide stable support for the mounting cylinder 3 and keep it stably on the same axis as the output shaft of the drive motor 2. In order to prevent the screws 52 from separating from the threaded sleeves 51 and to prevent the screws 52 from rotating and affecting the normal adjustment of the position of the mounting shell 53, a limit block is fixedly installed at the end of each of the three screws 52 that is far apart from each other. Each of the three mounting shells 53 has two stops fixedly installed on the side that is far apart from each other, which are in sliding contact with both sides of the support ring 5.

[0038] A geared disc 57 is rotatably mounted on the outer side of the support ring 5. A servo motor 54 is fixedly mounted on the support ring 5. A drive gear 55 is fixedly sleeved on the output shaft of the servo motor 54. A driven gear 56 is fixedly sleeved on each of the three threaded sleeves 51. All three driven gears 56 mesh with the geared disc 57. The drive gear 55 meshes with one of the driven gears 56. The distance between the three rollers 531 and the mounting cylinder 3 can be adjusted synchronously as needed, so that the device can better provide effective support for mounting cylinders 3 of different sizes.

[0039] Multiple fixing blocks 32 are fixedly installed on the inner wall of the mounting cylinder 3. A perforated plate 31 is slidably installed on the inner wall of the mounting cylinder 3. Multiple springs 34 are fixedly installed on the perforated plate 31. The multiple springs 34 are fixedly connected to the corresponding fixing blocks 32. After sampling, the perforated plate 31 can be pushed towards the sampling drill bit 4 under the action of the reaction force of the springs 34, thereby achieving the effect of assisting in sampling.

[0040] A vacuum cleaner 6 is fixedly installed on the support frame 1. The air inlet of the vacuum cleaner 6 is connected to a suction pipe. A mounting sleeve 61 connected to the output shaft of the drive motor 2 is rotatably and sealed on the output shaft of the drive motor 2. The suction pipe is connected to the mounting sleeve 61, which can extract dust and other debris generated during the drilling and sampling operation, thereby preventing dust and other debris from flying around.

[0041] In this embodiment, in order to ensure that the perforated plate 31 maintains stable sliding within the mounting cylinder 3, a plurality of guide rods 33 arranged in parallel to each other are fixedly installed on the perforated plate 31. The plurality of guide rods 33 are slidably connected to the corresponding fixed blocks 32, and a plurality of springs 34 are movably sleeved on the outer side of the corresponding guide rods 33. A plurality of guide grooves are provided on the inner wall of the mounting cylinder 3, and a plurality of guide blocks are fixedly installed on the outer periphery of the perforated plate 31. The plurality of guide blocks are slidably installed within the corresponding guide grooves.

[0042] In this embodiment, the vacuum cleaner 6 is a vacuum cleaner that can be used for both dry and wet applications, which is intended to extract the mixture of dust and water during the drilling and sampling process when water is used to cool the sampling drill bit. The sampling drill bit 4 has multiple through holes for collecting dust or cooling water during the drilling and sampling process, and can also improve its heat dissipation efficiency to a certain extent.

[0043] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0044] Working principle: When in use, first move the device to the location where drilling and sampling are required and connect the power supply. Then start the drive motor 2 and the vacuum cleaner 6. The drive motor 2 controls the mounting cylinder 3 to drive the sampling drill bit 4 to rotate synchronously. The operator controls the slider 12 to move the support frame 1 closer to the wall by turning the screw 13 through the handwheel, thereby realizing the drilling and sampling operation. During the drilling and sampling operation, the dust and other debris generated will be sucked out by the vacuum cleaner 6 through the holes on the sampling drill bit 4, the perforated plate 31, the mounting cylinder 3, the hollow output shaft of the drive motor 2 and the mounting sleeve 61, and then through the suction pipe, thereby achieving the dust removal effect.

[0045] When it is necessary to replace the sampling drill bit 4 of the same size, use a tool to press the convex column 44 in the direction of the axis of the mounting cylinder 3, so that the three arc blocks 41 drive the limit pin 43 to disengage from the limit groove. Then, remove the sampling drill bit 4 and replace it with a new sampling drill bit 4. When it is necessary to replace the sampling drill bit 4 of a different size, first use the servo motor 54 in conjunction with the drive gear 55, driven gear 56, gear plate 57, screw sleeve 51 and screw 52 to control the three mounting shells 53 to disengage from the mounting cylinder 3. Then, disconnect the output shaft of the drive motor 2 from the mounting cylinder 3, replace it with the mounting cylinder 3 of the required size and connect it to the output shaft of the drive motor 2. Then control the servo motor 54 to rotate in the opposite direction, so that the three rollers 531 can be synchronously controlled to move closer to and contact the mounting cylinder 3, thereby supporting the mounting cylinder 3. Then, install the sampling drill bit 4 of the corresponding size on the mounting cylinder 3 to achieve the effect of replacing the sampling drill bit 4 of a different size for sampling.

[0046] After sampling is completed, the sample often gets stuck in the sampling drill bit 4. After the sampling drill bit 4 and the mounting cylinder 3 are separated from the wall, the reaction force of the three springs 34 can push the perforated plate 31 towards the sampling drill bit 4, thereby achieving the effect of assisting in sample output.

[0047] The foregoing has provided a detailed description of a wall sampling device for quality inspection of building engineering provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
