Description

Technical Field

[0001] The utility model relates to the technical field of engineering supervision, in particular to a concrete strength detection device for engineering supervision. Background Art

[0002] Concrete strength testing devices used for project supervision play a vital role in the field of construction engineering. They are important tools to ensure project quality, safety and compliance with design requirements. Concrete strength is mainly used to evaluate the actual strength of concrete after pouring, that is, its ability to resist external force damage, thereby verifying whether the construction quality of the construction unit meets the standards. The application of concrete strength testing devices also promotes the transparency and traceability of the construction process, enabling supervision units to more effectively supervise the work quality of construction units and ensure that each process meets design requirements and relevant standards.

[0003] The existing Chinese patent with announcement number CN215115659U discloses a concrete strength detection device for engineering supervision, including a main body, a support column, a slide groove and a handle. The two ends of the main body are fixedly connected to the support columns, the inside of the support column is fixedly connected to the slide groove, the bottom end of the support column is fixedly connected to the base, the bottom middle position of the main body is fixedly connected to a control button, the top middle position of the main body is fixedly connected to a circular handle, the bottom middle position of the main body is fixedly connected to a drill bit, the top inner part of the main body is fixedly connected to a power distribution bin, the bottom middle position of the power distribution bin is fixedly connected to a motor, the bottom two sides of the power distribution bin are fixedly connected to a shock absorbing device, and the bottom end of the motor is fixedly connected to a drive block.

[0004] Although the above scheme can detect concrete blocks, the device lacks fixation of the concrete blocks during detection. If an offset occurs during detection, the loading force will no longer be evenly distributed on the entire concrete block, resulting in the measured compressive strength value deviating from the actual value. At the same time, there is a lack of effective protection during detection. If the concrete block breaks during detection, it is easy to splash and injure people, and the rupture of the concrete block is also easy to generate dust, affecting the detection. Therefore, it does not meet the existing needs. In this regard, we propose a concrete strength detection device for engineering supervision. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] It also includes a transmission chamber 6, which is opened on the rear side of the main body 1. A double-threaded transmission rod 7 is rotatably provided inside the transmission chamber 6. Both sides of the outer side of the double-threaded transmission rod 7 are threadedly connected to a moving block 9. The front end of the moving block 9 is welded with a connecting block 12. One end of the connecting block 12 passes through and extends into the interior of the detection chamber 3.

[0028] It also includes a rotating rod 13, which is rotatably arranged inside the connection block 12 at one end inside the detection chamber 3. Both ends of the rotating rod 13 pass through and extend to the outside of the connection block 12. The lower end of the rotating rod 13 is provided with a rubber fixing block 15;

[0029] The main body 1 further comprises a dust collecting chamber 16 , which is arranged at the rear side of the upper end of the main body 1 . A plurality of dust-proof nets 20 equidistantly distributed are arranged inside the dust collecting chamber 16 .

[0030] During use, the protective door 2 is used to protect the safety of the detection process. A concrete block is placed in the detection chamber 3, and the strength test is carried out using the hydraulic rod 4 and the detection head 5. The handwheel 11 drives the rotating shaft 10 to drive the double-threaded transmission rod 7, so that the moving block 9 moves in a straight line along the guide rod 8. The rubber fixing block 15 is adjusted by the connecting block 12, the rotating rod 13 and the knob 14 to firmly fix concrete blocks of different sizes. During the detection, the suction machine 19 collects the dust in the detection chamber through the dust collecting chamber 16, the connecting pipe 18 and the dust suction port 17. The dustproof net 20 intercepts the dust to keep the detection environment clean. The transparent glass window facilitates observation to ensure safe and efficient operation.

[0031] See also Figure 1 and Figure 2A rotating shaft 10 is provided at one end of the double-threaded transmission rod 7. One end of the rotating shaft 10 passes through and extends to the outside of the transmission cavity 6, and the rotating shaft 10 rotates with the transmission cavity 6. A handwheel 11 is installed at one end of the rotating shaft 10 located outside the transmission cavity 6. The handwheel 11 can be easily operated from the outside, and the rotational force is transmitted to the double-threaded transmission rod 7 through the rotating shaft 10, thereby driving the moving block 9 to move horizontally, thereby realizing flexible adjustment of the position of the rubber fixing block 15;

[0032] See also Figure 2 and Figure 3 Guide rods 8 are welded on the upper and lower sides of the transmission cavity 6. The guide rods 8 all pass through the moving block 9, and the guide rods 8 all slide with the moving block 9. The guide rods 8 provide a stable moving trajectory for the moving block 9, preventing the moving block 9 from deflecting or shaking during movement, ensuring that the rubber fixing block 15 can accurately and stably move to the specified position, thereby improving the accuracy and reliability of the fixation;

[0033] See also Figure 3 An aspirator 19 is provided in front of the dust collecting chamber 16, and the aspirator 19 is connected to the dust collecting chamber 16. The aspirator 19 can effectively suck the dust generated in the detection chamber into the dust collecting chamber 16, reduce the dust concentration in the detection chamber 3 through the negative pressure effect, keep the detection environment clean, and also protect the health of the detection equipment and operators;

[0034] See also Figure 4 , a knob 14 is installed on the upper end of the rotating rod 13, and the knob 14 provides a convenient adjustment means for the operator. By rotating the knob 14, the rotating rod 13 and the rubber fixing block 15 can be driven to move up and down, thereby achieving the fastening and fixation of the concrete block. The design of the knob 14 makes the adjustment process more intuitive and labor-saving;

[0035] See also Figure 1 and Figure 3 A dust suction port 17 is provided on the upper side of the rear end of the detection chamber 3. The dust suction port 17 is connected to the dust collecting chamber 16 through a connecting pipe 18. The dust suction port 17 can accurately capture the dust escaping from the detection chamber and guide it into the dust collecting chamber 16 through the connecting pipe 18 for collection and treatment, effectively preventing the accumulation and dispersion of dust in the detection chamber, thereby ensuring the cleanliness of the detection environment and the clarity of the observation field;

[0036] See also Figure 1 A protective door 2 is movably installed on one side of the front end of the main body 1, and a transparent glass window is installed inside the protective door 2. The protective door 2 can effectively isolate potential dangers during the detection process, such as splashing concrete blocks, to protect the safety of the operator. The transparent glass window allows the operator to observe the detection process without opening the protective door, thereby improving the convenience and safety of the operation.

[0037] Working principle: when in use, open the protective door 2 and place the concrete block to be tested at the lower end of the detection chamber 3, turn the handwheel 11, the handwheel 11 will drive the rotating shaft 10 to rotate, and the rotating shaft 10 will drive the double-threaded transmission rod 7 to make the two moving blocks 9 rotate synchronously. Since the moving blocks 9 are slidably matched with the two guide rods 8, the rotation of the moving blocks 9 will be subject to axial limitation, and the rotation of the two moving blocks 9 will be converted into horizontal linear movement. When the two moving blocks 9 move, they will drive the connecting block 12 to move synchronously, and the connecting block 12 will drive the rotating rod 13 to move synchronously, and move the rotating rod 13 to the upper end of the concrete block. At this time, you can turn the knob 14, and the knob 14 will drive the rotating rod 13 to rotate synchronously, so that the rubber fixing block 15 moves downward synchronously, so that the rubber fixing block 15 squeezes and fits the concrete block, avoiding the random movement of the concrete block, and realizing the firm fixation of the concrete block during the detection process. By controlling the distance between the two moving blocks 9, the spacing of the rubber fixing blocks 15 can be controlled, thereby achieving effective fixation of concrete blocks of different sizes and increasing the scope of application. After fixing the concrete blocks, the protective door 2 can be closed. Closing the protective door 2 can avoid the concrete blocks from splashing and injuring people during detection, thereby increasing safety. The transparent glass window on the protective door 2 is convenient for the operator to observe. The strength test is performed through the hydraulic rod 4 and the detection head 5. The suction machine 19 can be started during the test. The suction machine 19 will extract the air in the dust collecting chamber 16, so that the inside of the dust collecting chamber 16 is under negative pressure to generate suction. The dust suction port 17 can be connected to the connecting pipe 18 to suck the dust scattered in the detection chamber into the interior of the dust collecting chamber 16. The dust can be intercepted by multiple dustproof nets 20, thereby preventing dust from floating and accumulating in the detection chamber 3, thereby ensuring the cleanliness of the detection environment and the clarity of the observation field.
