Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and specifically relates to a building strength measuring device for construction engineering. Background Art

[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their ancillary facilities and the installation of pipelines and equipment supporting them. The most common one is housing buildings, and also includes walls, roads, dams, wells, tunnels, water towers, bridges, chimneys, etc. The above-mentioned buildings are mainly composed of reinforced concrete. When detecting the strength of these buildings, a piece of reinforced concrete needs to be taken for submission for inspection to detect the strength of the building. Therefore, we introduce a building strength measuring device for construction engineering.

[0003] The existing patent (publication number: CN116678726A) discloses a concrete strength detection device for construction engineering. The invention provides a concrete strength detection device for construction engineering with various detection methods. A concrete strength detection device for construction engineering includes a connecting frame, a detection frame, a detection cylinder, a detection plate, and a repeated impact mechanism. The inner bottom of the connecting frame is connected with a detection frame. The upper side of the rear part inside the detection frame is provided with a detection cylinder. The telescopic rod of the detection cylinder is connected with a detection plate for detecting the strength of concrete. A repeated impact mechanism for knocking the concrete is arranged between the detection plate and the detection frame. The invention detects the strength of concrete by driving the detection plate to move downward by the telescopic rod of the detection cylinder. The rapid detection rod moves downward to impact the concrete, and the repeated punching rod punches the concrete multiple times to achieve the detection effect. The various detection methods make the result more accurate. The existing technology has the following problems: When the existing strength detection device detects, it will perform operations such as extruding the concrete. In this process, there will be flying debris. On the one hand, it is easy to hurt people. On the other hand, it is difficult to clean up after the detection. The flying concrete debris often falls in the peripheral area of the main part of the concrete. When it is necessary to continuously detect multiple pieces of concrete, the workbench needs to be cleaned after each piece of concrete is detected. Otherwise, it will affect the flatness of the placement of the subsequent concrete blocks, and the frequent cleaning slows down the detection efficiency. Summary of the Invention

Detailed implementation manners

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 to 6, the present invention provides a technical solution: a building strength measuring device for construction engineering, including a machine body 1, with limiting sliding grooves 2 opened on both sides of the inner wall of the machine body 1, a protection component 3 and a vacuum adsorption component 4 are respectively provided on the bottom surface of the machine body 1, a hydraulic push rod 5 is fixedly connected to the inner top of the machine body 1, a detection head 6 is fixedly connected to the output end of the hydraulic push rod 5, a cleaning component 7 is movably connected to one side of the protection component 3, and an inclined guiding groove one 8 is opened on the top of the machine body 1.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 4 and Figure 6As shown in the figure, the cleaning component 7 includes a follower rod 701 that movably penetrates through the middle of the protection component 3. An approximately elliptical plate one 702 is integrally formed in the middle of the follower rod 701. The follower rod 701 is fixedly connected to the outer surface of the buffer slider 7024. The buffer slider 7024 is slidably sleeved on the outside of the fixed rod 7025. A buffer spring 7026 is fixedly connected between the end of the fixed rod 7025 and the buffer slider 7024. The fixed rod 7025 is integrally formed on one side of the cleaning rod one 703. One end of the cleaning rod one 703 is fixedly connected with a T-shaped limit block 704. The T-shaped limit block 704 is slidably connected inside the T-shaped limit groove 705. The T-shaped limit groove 705 is opened on one side of the fixed plate 706 close to the cleaning rod one 703. A linear limit groove 707 is opened on the top surface of the cleaning rod one 703. An extension groove 708 is opened on the inner wall of the linear limit groove 707. An approximately elliptical plate two 709 is slidably connected inside the extension groove 708. The approximately elliptical plate two 709 is integrally formed in the middle of the bottom end of the vertical movable rod 7010. A sliding rod 7011 is fixedly connected to the middle of the vertical movable rod 7010. The sliding rod 7011 slidably penetrates through the avoidance hole 7012. The avoidance hole 7012 is opened in the middle of the moving frame 7013. One side of the moving frame 7013 close to the middle of the machine body 1 is fixedly connected with an L-shaped frame 7015 through a spring telescopic rod 7014. A piston rod 7016 slidably penetrates through the middle of the L-shaped frame 7015. A cleaning block one 7017 is integrally formed at the bottom end of the piston rod 7016. The top end of the piston rod 7016 extends into the air cavity 7018. One side of the air cavity 7018 away from the middle of the machine body 1 is communicated with an air pipe 7019. And a sealing strip 7020 is slidably connected to one side of the air cavity 7018 close to the middle of the machine body 1. A T-shaped slider 7021 is integrally formed at the top end of the L-shaped frame 7015. The T-shaped slider 7021 is slidably connected to the middle of the T-shaped chute 7022. A cleaning block two 7023 is fixedly connected to the bottom surface of the cleaning rod one 703. A multi-stage telescopic rod 7028 is fixedly installed on the bottom surface of the L-shaped frame 7015. The T-shaped chute 7022 is opened at the inner top of the machine body 1. The inclined guide groove one 8 at the top of the machine body 1 is a through groove. And the vertical movable rod 7010 penetrates through the middle of the inclined guide groove one 8. One side of the sealing strip 7020 away from the air cavity 7018 is fixedly connected with a passive telescopic rod 7027. One end of the passive telescopic rod 7027 away from the sealing strip 7020 is fixedly connected with the top surface of the detection head 6 through a vertical mounting plate. An expansion groove 309 is opened on the inner wall of the inclined guide groove two 308. The inside of the expansion groove 309 is slidably connected with the approximately elliptical plate one 702. And the follower rod 701 penetrates through the middle of the inclined guide groove two 308; In actual use, first place the building concrete block to be subjected to strength detection on the detection table 403. Then start the hydraulic push rod 5 to extend and push the detection head 6 to move downward. During the downward movement of the detection head 6, it will drive the lifting plate 302 to move downward synchronously through the special-shaped connecting rod 301. When the lifting plate 302 moves downward, it will squeeze the follower rod 701 through the inclined guide groove two 308.The follower rod 701 is finally integrated with the T-shaped limit block 704 through the cleaning rod 1 703. The T-shaped limit block 704 can only slide linearly along the T-shaped limit groove 705. Therefore, when the lifting plate 302 moves downward, it will drive the follower rod 701 to approach the concrete block on the test bench 403. The follower rod 701 drives the fixed rod 7025 to approach or move away from the concrete block through the buffer slider 7024 and the buffer spring 7026. The fixed rod 7025 drives the cleaning rod 1 703 to approach the concrete block, and the cleaning rod 1 703 drives the cleaning block 2 7023 on the bottom surface to move synchronously. When the cleaning rod 1 703 is in contact with the front and rear sides of the concrete block, the detection head 6 continues to move downward, and the lifting plate 302 will continue to squeeze the follower rod 701 towards the middle of the body 1. At this time, the follower rod 701 will slide along the fixed rod 7025 and squeeze the buffer spring 7026. Moreover, during the process of the cleaning rods 1 703 on the front and rear sides approaching each other, the concrete block on the test bench 403 can be automatically centered in the front and rear directions. During the process of the cleaning rod 1 703 approaching the concrete block, it will also drive the sliding rod 7011 to move synchronously through the vertical movable rod 7010. Since the vertical movable rod 7010 passes through the middle of the inclined guide groove 1 8, when the vertical movable rod 7010 moves with the cleaning rod 1 703, it will be squeezed by the inclined guide groove 1 8, causing the vertical movable rod 7010 to slide along the inside of the linear limit groove 707 towards the direction of the concrete block to be detected. During this process, the vertical movable rod 7010 drives the moving frame 7013 to approach the concrete block synchronously through the sliding rod 7011. The moving frame 7013 drives the L-shaped frame 7015 to move synchronously through the spring telescopic rod 7014. The multi-stage telescopic rod 7028 at the bottom of the L-shaped frame 7015 will first contact the two sides of the concrete block. The multi-stage telescopic rod 7028 can prevent the projection of the L-shaped frame 7015 from crossing the edge of the concrete block from the top view, so as to prevent affecting the subsequent descent of the cleaning block 1 7017. Moreover, this structure can also automatically center the concrete block left and right. Combining with the above-mentioned front and rear centering functions, it can automatically complete the centering and fixing of the concrete block, preventing the detection position from deviating during the detection process. After completing the left and right centering, the detection head 6 also drives the top of the sealing strip 7020 to move downward below the top surface of the air cavity 7018. At this time, the internal space of the air cavity 7018 is connected to the external space, so the negative pressure in the air cavity 7018 disappears. Under the action of gravity, the cleaning block 1 7017 descends to the position where it contacts the top surface of the test bench 403, and the cleaning block 1 7017 near the edge falls on the top of the cleaning rod 1 703. This structure can prevent the cleaning rods 1 703 in the front and rear directions and the cleaning blocks 1 7017 in the left and right directions from approaching the concrete block simultaneously and interfering. Therefore, after the centering of the concrete block is completed, the cleaning blocks 1 7017 in the left and right directions will fall, and then the detection will be carried out. During the detection process, the concrete block will be damaged, and the concrete fragments will fall on the test bench 403 at the edge of the concrete block. After the detection is completed,The above cleaning component 7 runs in reverse. At this time, the first cleaning block 7017 and the second cleaning block 7023 both move outward along the detection table 403, sweeping the debris on the top surface of the detection table 403 off the detection table 403 to achieve the purpose of cleaning the detection table. Under the limiting action of the T-shaped slider 7021 and the T-shaped sliding groove 7022, the L-shaped frame 7015 is connected to the avoidance hole 7012 in a sliding manner through the sliding rod 7011, so that the moving frame 7013 will not displace in the front-back direction. The first elliptical-like piece 702 can prevent the follower rod 701 from rotating around its own axis, and the second elliptical-like piece 709 can prevent the vertical movable rod 7010 from rotating on its own axis.,

[0030] In this embodiment, as Figures 1 to 3 shown, the protection component 3 includes a special-shaped connecting rod 301 fixedly connected to the rear side of the detection head 6. Both ends of the special-shaped connecting rod 301 far from the detection head 6 are fixedly connected with lifting plates 302. On the side of the lifting plate 302 close to the middle of the machine body 1, a driving rack 303 is integrally formed. The driving rack 303 meshes with a transmission gear 304. On the side of the transmission gear 304 far from the driving rack 303, a driven rack 305 is meshed. The bottom end of the driven rack 305 is fixedly connected with a cross beam 306. The cross beam 306 is integrally formed at the bottom of the inner wall of the protection enclosure 307. An inclined guide groove 308 is formed in the middle of one side of the lifting plate 302; when the detection head 6 moves downward, the lifting plate 302 is driven to descend through the special-shaped connecting rod 301. The descent of the lifting plate 302 will drive the transmission gear 304 to rotate through the driving rack 303, and the rotation of the transmission gear 304 will drive the driven rack 305 to move upward. The upward movement of the driven rack 305 penetrates the fixed platform 401 and drives the protection enclosure 307 to move upward through the cross beam 306 to enclose the detection table 403, avoiding the flying of debris generated during detection from hurting people. Note that the transmission gear 304 is rotatably connected to the bottom surface of the top plate of the fixed platform 401 through a mounting plate.

[0031] In this embodiment, as Figures 2 to 5As shown in the figure, the vacuum adsorption assembly 4 includes a fixed platform 401 and a vacuum fan 402 that are respectively fixedly connected to the inner bottom surface of the machine body 1. The top surface of the fixed platform 401 is fixedly connected to a detection table 403. An air duct 404 is integrally formed between the upper and lower inner walls of the detection table 403. A spring telescopic column 405 is fixedly connected to the inner bottom surface of the air duct 404. A connecting ball 406 is integrally formed at the top end of the spring telescopic column 405. The connecting ball 406 is movably embedded in the middle of the bottom surface of the extrusion block 407. An airbag 408 is fixedly connected to the middle of the extrusion block 407. Ventilation holes 409 are provided in the area of the air duct 404 where the outer circle of the airbag 408 fits. The vacuum fan 402 is located directly below the detection table 403. The detection table 403 is connected to the vacuum fan 402 through a pipeline, and both sides of the detection table 403 are connected to the air pipe 7019. When the vacuum fan 402 in the vacuum adsorption assembly 4 is started, since the vacuum fan 402 is connected to the inside of the detection table 403, and the detection table 403 is connected to the air cavity 7018 through the air pipe 7019, the vacuum fan 402 can pump out the air in the detection table 403 and the air cavity 7018 to form a negative pressure. When a negative pressure is formed in the air cavity 7018, the cleaning block 7017 can be attracted upward and reset. When the concrete block is placed on the top surface of the detection table 403, the concrete block will press down the extrusion block 407 and move it downward. When the extrusion block 407 moves downward, it will drive the airbag 408 to move downward synchronously, causing the airbag 408 to be misaligned with the ventilation holes 409. At this time, the air duct 404 is connected to the inside of the detection table 403, and the negative pressure is used to adsorb the concrete block on the detection table 403 for fixation. The design of the connecting ball 406 allows the extrusion block 407 to tilt at an angle. This structure can prevent the extrusion block 407 from tilting when the concrete block does not completely cover the top area of the extrusion block 407, thereby avoiding the ventilation holes 409 in the area of the extrusion block 407 not covered by the concrete block from being opened, resulting in the connection between the internal space of the detection table 403 and the outside world and the decrease in the adsorption effect of the detection table 403 on the concrete block.

[0032] The usage method and advantages of the present invention: When this building strength measuring device for construction engineering is in use, the working process is as follows:

[0033] First, place the concrete block on the test bench 403. The self-weight of the concrete block causes the descending extrusion block 407 to open the ventilation hole 409, thereby adsorbing the concrete block and enhancing the stability of the placement of the concrete block. Then, the detection head 6 moves downward, driving the cleaning component 7 to approach the concrete block and finally fit with the edge of the concrete block to automatically calibrate the position and clamp the concrete block. During the downward movement of the detection head 6, it also drives the protection component 3 to start, protecting the test bench 403 in the middle to avoid the situation of debris splashing out and hurting people during the detection process. After the detection is completed, during the reset process of the cleaning component 7, the slag falling from the edge of the concrete block is automatically swept off the test bench 403, saving the steps for the staff to manually clean the test bench 403 and improving the detection efficiency.
