Description

Technical Field

[0001] This utility model relates to the field of building engineering quality testing technology, and more specifically, it relates to a wall sampling device for building engineering quality testing. Background Technology

[0002] In the field of building engineering quality testing, walls, as the core load-bearing and enclosure components of building structures, directly determine the overall safety and durability of buildings based on the test results of indicators such as material strength, density, and construction compliance. Wall sampling is a crucial step in obtaining these indicators. Testing personnel need to use sampling devices to drill wall samples, such as cylindrical samples of materials like concrete and brick masonry, and then analyze the mechanical properties and composition of the samples in the laboratory to determine whether the walls meet design specifications and quality standards. Therefore, the standardization, efficiency, and environmental friendliness of the sampling process have a significant impact on the accuracy of testing work and the on-site work experience.

[0003] An existing wall sampling device for building construction quality inspection is used as follows: 1. Existing devices generate a large amount of dust during the sampling process. This dust has no collection constraints and diffuses directly into the surrounding air, increasing subsequent cleaning costs and affecting the surrounding environment, thus resulting in poor practicality.

[0004] 2. The existing device lacks a dedicated sample collection structure. After drilling, the wall sample needs to be manually collected by the testing personnel holding a container below the drilling location, which increases the workload of the staff and thus results in poor practicality. Utility Model Content

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a wall sampling device for building engineering quality testing, comprising a mounting frame, a sampling drill assembly at the front end of the mounting frame, a mounting plate at the bottom of the mounting frame, a sliding assembly at the bottom of the mounting plate, a base slidably connected to the bottom of the mounting plate via the sliding assembly, four sets of movable wheels evenly arranged at the bottom of the base, a sleeve at the front end of the mounting frame, the inner side of the sleeve fitting onto the outer side of the sampling drill assembly, a pre-drilled hole at the front end of the bottom of the sleeve, a connecting pipe disposed within the pre-drilled hole, a fixed seat at the rear end of the outer side of the sleeve, a support plate at the bottom front end of the fixed seat, a mounting block at the top of the support plate, a working cavity in the mounting block, a pre-drilled hole at the top of the working cavity of the mounting block, the other end of the connecting pipe connected to the pre-drilled hole of the mounting block, and a collection mechanism disposed within the working cavity of the mounting block.

[0007] The present invention is further configured such that the collection mechanism includes a collection box, a through hole is provided at the right end of the working cavity of the mounting block, and the outer side of the collection box passes through the through hole of the mounting block and slides tightly against the inner wall of the working cavity of the mounting block. A cover plate is provided at the right end of the collection box, and the left end of the cover plate is tightly against the right end of the mounting block. Fixing components are provided on the right sides of both the front and rear ends of the mounting block, and the right sides of both the front and rear ends of the mounting block are connected to the left end of the cover plate through the fixing components. The sliding fit and sealing design of the collection box and the working cavity of the mounting block ensure that dust and samples are always confined within the collection box. The collection box can be removed and cleaned as a whole without disassembling the mounting block, which is convenient to operate and solves the defects of existing sample collection that require cleaning each component one by one, which is time-consuming and laborious, greatly shortening the cleaning time and improving the sampling efficiency.

[0008] The present invention is further configured such that the fixing component includes two sets of positioning blocks and two sets of positioning screws. Positioning blocks are provided on the rear sides of both ends of the mounting block, and connecting plates are provided on both the front and rear sides of the left end of the cover plate. Each of the two sets of connecting plates has a slot at one end opposite to the other end. The other ends of the two sets of positioning blocks are respectively engaged with the corresponding slots of the connecting plates. The slots of the two sets of connecting plates are respectively provided with threaded holes through the corresponding sets of positioning blocks. The outer sides of the two sets of positioning screws are threadedly connected to the corresponding sets of positioning blocks and the slots of the connecting plates through the threaded holes. The engagement of the positioning blocks with the slots of the connecting plates provides initial positioning for the cover plate and the collection box, improving the installation efficiency of the collection box. The symmetrical distribution of the two sets of positioning blocks and positioning screws ensures that the cover plate and the collection box are subjected to balanced forces, making the locking more secure and preventing the collection box from loosening, dust leakage, or sample displacement due to device vibration during sampling, thereby improving the stability and reliability of the collection mechanism.

[0009] The present invention is further configured such that the sliding component includes a drive motor, the top of the base is provided with a sliding groove, a connecting screw is rotatably disposed in the sliding groove of the base, a drive block is threadedly connected to the outer side of the connecting screw, the bottom of the drive block is slidably connected to the sliding groove of the base, and the top of the drive block is connected to the bottom of the mounting plate, the rear end of the base is provided with a drive motor, and the front output end of the drive motor is connected to the rear end of the connecting screw; the cooperation of the drive motor, the connecting screw and the drive block realizes the automatic adjustment of the sampling position, eliminating the need for manual pushing of the mounting bracket, and allowing the front end of the sleeve to quickly fit against the wall.

[0010] The present invention is further provided with an annular sponge pad at the front end of the sleeve; the elastic sealing effect of the annular sponge pad fills the gap between the sleeve and the wall, further improving the dust control effect, protecting the health of the testing personnel, and preventing dust from contaminating the wall surface.

[0011] The present invention is further provided with an auxiliary handle at the right end of the cover plate; this provides a clear force point for placing and removing the cover plate and the collection box, thereby improving the convenience and safety of operation.

[0012] The present invention is further configured such that each of the two sets of positioning screws is provided with a rotating handle at one end; this increases the force application radius of the positioning screws and improves the operating efficiency of the fixing components.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a wall sampling device for quality inspection of building engineering, which has the following beneficial effects: 1. The combination of the base and the casters allows the device to move flexibly, adapting to the sampling needs of different floors and wall locations, improving operational flexibility. The sleeve's containment effect on the sampling drill assembly reduces dust diffusion at the source. Combined with the dust conveying and collection function of the connecting pipe and the collection mechanism, it reduces the impact of dust pollution on the environment during sampling by existing devices, improving the on-site working environment of the testing site.

[0014] 2. The sliding fit and sealing design of the collection box and the working chamber of the mounting block ensure that dust and samples are always confined inside the collection box. The collection box can be removed as a whole for cleaning without disassembling the mounting block, making the operation convenient. This solves the problem of existing sample collection methods that require cleaning each component one by one, which is time-consuming and labor-intensive, and greatly shortens the cleaning time and improves the sampling efficiency.

[0020] Please see Figure 1-5A wall sampling device for quality inspection of building construction includes a mounting frame 1, a sampling drill assembly 2 at the front end of the mounting frame 1, a mounting plate 3 at the bottom of the mounting frame 1, a sliding assembly at the bottom of the mounting plate 3, a base 4 slidably connected to the bottom of the mounting plate 3 via the sliding assembly, four sets of movable wheels 5 evenly arranged at the bottom of the base 4, a sleeve 6 at the front end of the mounting frame 1, the inner side of the sleeve 6 fitting onto the outer side of the sampling drill assembly 2, a pre-drilled hole at the front end of the bottom of the sleeve 6, a connecting pipe 7 inside the pre-drilled hole of the sleeve 6, a fixing seat 8 at the rear end of the outer side of the sleeve 6, a support plate 9 at the bottom front end of the fixing seat 8, a mounting block 10 at the top of the support plate 9, a working chamber in the mounting block 10, a pre-drilled hole at the top of the working chamber of the mounting block 10, the other end of the connecting pipe 7 connecting to the pre-drilled hole of the mounting block 10, and a collection mechanism inside the working chamber of the mounting block 10.

[0021] In this embodiment, when sampling the wall, the mounting frame 1 is pushed, and the moving wheels 5 at the bottom of the base 4 roll, moving the entire device to the vicinity of the wall to be sampled. The sliding assembly is activated, and the mounting plate 3 slides along the base 4 via the sliding assembly. The mounting frame 1 moves synchronously with the mounting plate 3, thereby driving the front sleeve 6 to gradually approach the wall until the front end of the sleeve 6 is in contact with the wall surface. The operator activates the sampling drill assembly 2, which rotates along the inside of the sleeve 6 to drill into the wall. The wall sample and dust generated during the drilling process are contained inside the sleeve 6, preventing them from directly spreading into the air. The sample and dust are transported through the connecting pipe 7 in the pre-drilled hole at the bottom front end of the sleeve 6 to the working chamber of the mounting block 10 at the top of the support plate 9, and finally fall into the collection mechanism in the working chamber. After sampling is completed, the sampling drill assembly 2 is turned off, and the sliding assembly is activated in reverse. The mounting plate 3 drives the mounting frame 1 and the sleeve 6 away from the wall, completing one sampling operation.

[0022] More specifically, when adjusting the sampling position, the drive motor 15 at the rear end of the base 4 is started. The output end of the drive motor 15 drives the connecting screw 16 in the slide groove of the base 4 to rotate. When the connecting screw 16 rotates, the drive block 17 connected to its outer thread slides along the slide groove of the base 4. The top of the drive block 17 is connected to the bottom of the mounting plate 3, thereby driving the mounting plate 3, the mounting bracket 1, the sleeve 6 at the front end, and the sampling drill assembly 2 to move synchronously. By controlling the forward and reverse rotation of the drive motor 15, the mounting plate 3 can be slid back and forth, thereby adjusting the distance between the sleeve 6 and the wall.

[0023] Please see Figure 1 and Figure 4As one embodiment of the collection mechanism: the collection mechanism includes a collection box 11, a through hole is provided at the right end of the working cavity of the mounting block 10, and the outer side of the collection box 11 passes through the through hole of the mounting block 10 and slides tightly against the inner wall of the working cavity of the mounting block 10. A cover plate 12 is provided at the right end of the collection box 11, and the left end of the cover plate 12 is tightly against the right end of the mounting block 10. Fixing components are provided on the right sides of both the front and rear ends of the mounting block 10, and the right sides of both the front and rear ends of the mounting block 10 are connected to the left end of the cover plate 12 through the fixing components.

[0024] Specifically, during the sampling process, the wall sample and dust transported to the working chamber of the mounting block 10 via the connecting pipe 7 fall naturally into the collection box 11 inside the working chamber. The outer side of the collection box 11 slides tightly against the inner wall of the working chamber of the mounting block 10, forming a relatively closed space to prevent dust from leaking out from the gaps. When a certain amount of sample and dust accumulates in the collection box 11, the fixing components on the right side of both ends of the mounting block 10 are operated to release the fixing components from locking the cover plate 12. Then, the cover plate 12 is pulled, and the cover plate 12 drives the collection box 11 to slide along the through hole at the right end of the working chamber of the mounting block 10 until the collection box 11 is completely detached from the working chamber. The wall sample in the collection box 11 is taken out, the dust inside the box is cleaned, and the collection box 11 is pushed back into the working chamber of the mounting block 10 so that the left end of the cover plate 12 is tightly against the right end of the mounting block 10. Then, the fixing components are used to fix the cover plate 12 to the mounting block 10, restoring the collection function to prepare for the next sampling.

[0025] Please refer to Figures 2-4 As a further embodiment of the collection mechanism: the fixing component includes two sets of positioning blocks 13 and two sets of positioning screws 14. Positioning blocks 13 are provided on the rear sides of both ends of the mounting block 10. Connecting plates 21 are provided on both the front and rear sides of the left end of the cover plate 12. Each of the two sets of connecting plates 21 has a slot at one end opposite to the other end. The other ends of the two sets of positioning blocks 13 are respectively engaged with the slots of the corresponding set of connecting plates 21. The slots of the two sets of connecting plates 21 are respectively provided with threaded holes through the corresponding set of positioning blocks 13. The outer sides of the two sets of positioning screws 14 are threadedly connected to the corresponding set of positioning blocks 13 and the slots of the connecting plates 21 through the threaded holes.

[0026] Specifically, when fixing the collection box 11, push the collection box 11 into the working cavity of the mounting block 10 so that the left end of the cover plate 12 fits against the right end of the mounting block 10. At this time, the connecting plates 21 on the front and rear sides of the left end of the cover plate 12 move with the cover plate 12. The slot at the opposite end of the connecting plate 21 aligns with the positioning blocks 13 on the rear sides of the front and rear ends of the mounting block 10. Continue to push the cover plate 12 so that the positioning blocks 13 are inserted into the slots of the connecting plate 21. Pass the positioning screw 14 through the threaded hole provided between the slot of the connecting plate 21 and the positioning block 13. Rotate the positioning screw 14 so that its outer side is tightly connected with the threaded hole. Lock the positioning block 13 and the connecting plate 21 through the threaded fastening force, thereby fixing the cover plate 12 and the collection box 11 and preventing the collection box 11 from moving during the sampling process.

[0027] In summary, the overall equipment is in use (or running): The four sets of moving wheels 5 at the bottom of the base 4 are driven by the pushing device, which moves the device to the wall to be sampled. The drive motor 15 of the sliding component is started. The output end of the drive motor 15 drives the connecting screw 16 in the slide groove of the base 4 to rotate. The drive block 17 on the outside of the connecting screw 16 slides along the slide groove. The mounting plate 3 on the top of the drive block 17 moves with it, so that the sleeve 6 at the front end of the mounting bracket 1 is close to the wall until the annular sponge pad 18 at the front end of the sleeve 6 is in close contact with the wall.

[0028] Start the sampling drill assembly 2 at the front end of the mounting frame 1. The sampling drill assembly 2 rotates along the inner side of the sleeve 6 to drill the wall. The generated sample and dust are blocked by the sleeve 6 and transported through the connecting pipe 7 in the pre-drilled hole at the bottom of the sleeve 6 to the working chamber of the mounting block 10 on the bottom support plate 9 at the front end of the fixed seat 8, and fall into the collection box 11 in the working chamber.

[0029] After sampling is completed, reverse the start of drive motor 15 to move sleeve 6 away from the wall, rotate the rotating handle 20 at one end of positioning screw 14, positioning screw 14 disengages from the threaded hole of positioning block 13 and connecting plate 21 slot, positioning block 13 disengages from connecting plate 21 slot, release the locking component on cover plate 12, pull the auxiliary handle 19 at the right end of cover plate 12 to pull collection box 11 out from working chamber of mounting block 10, take out the sample and clean the dust, reset collection box 11, and relock it through the fixing component to complete sampling.

[0030] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
