Abstract
Description
Technical Field
[0001] This application relates to the technical field of concrete testing, and particularly to an automated testing device for the impermeability performance of concrete. Background Art
[0002] Concrete, simply referred to as "砼", is a general term for engineering composite materials in which aggregate is cemented into a whole by cementitious materials. Usually, the term "concrete" refers to the use of cement as the cementitious material and sand and stone as the aggregate. The impermeability of concrete refers to the performance of the concrete used in buildings to resist the penetration of water and other liquid media under pressure. The impermeability performance of concrete needs to be detected using an automated testing device.
[0003] After retrieval, the existing patent publication number is CN218847925U, which discloses a testing device for the impermeability performance of concrete, including a machine case. A mold base is fixedly connected to the top of the machine case. There are three mold bases in total, and the three mold bases are evenly arranged on the top surface of the machine case. A test mold is arranged above the mold base. A cavity is opened inside the machine case. A rotating block is movably connected to the outer wall of the machine case. A covering mechanism is fixedly connected to the inner end of the rotating block. The covering mechanism includes a screw rod and a first lifting rod. The screw rod is fixedly connected to the rotating block. The screw rod is a ball screw rod. The position of the screw rod is in the cavity. A slider is movably connected to the outer wall of the screw rod. The top end of the slider is rotatably connected to a push rod. There are multiple push rods in total. The push rod is rotatably connected to the bottom end of the first lifting rod. Through the action of the covering mechanism, the test mold can accurately cover the mold base and the concrete test block, without the need for manual adjustment of the position of the test mold, thereby improving work efficiency.
[0004] Although the above patent can make the test mold accurately cover the mold base and the concrete test block, without the need for manual adjustment of the position of the test mold, the number of test molds of the testing device is relatively large. It is necessary to manually twist the rotating block one by one to cover multiple test molds on the concrete test block. Such an operation is still not convenient enough, and it is impossible to cover multiple test molds on the concrete test block simultaneously, resulting in the work efficiency still not being high enough.

[0006] This application provides an automated testing device for the impermeability of concrete, comprising an automated testing device body. A portal-shaped mounting plate is connected to the outer side of the automated testing device body via multiple sets of bolts. A servo motor is fixedly connected to the top of the portal-shaped mounting plate. The drive shaft of the servo motor passes through the top of the portal-shaped mounting plate and is welded with a one-way lead screw. A nut is connected to the outer wall of the one-way lead screw, and the nut is fixedly connected to the interior of a protrusion of a T-shaped mounting block. A bearing is fixedly connected to the side of the T-shaped mounting block, and a fixed shaft is connected inside the bearing. Multiple sets of fixed cylinders are welded to the outer wall of the fixed shaft. A connecting column is welded to the bottom of each set of fixed cylinders. A test mold is fixedly connected to the bottom end of the connecting column. A mold base is provided below the test mold. Multiple sets of mold bases are fixedly installed on the top of the automated testing device body.
[0007] Preferably, the T-shaped mounting block has a through hole inside, and a guide rod is slidably connected inside the through hole. The guide rod is fixedly connected to the inner side of the gate-shaped mounting plate.
[0008] Preferably, a pulley is fixedly connected to the outer wall of the first unidirectional lead screw, a transmission belt is connected to the outside of the pulley, another set of pulleys is connected inside the transmission belt, and a second unidirectional lead screw is fixedly connected inside the other set of pulleys.
[0009] Preferably, the outer wall of the unidirectional lead screw is connected to a lead screw nut, which is fixedly connected to the inside of the protrusion of the T-shaped mounting block, and another set of bearings is fixedly connected to the side of the T-shaped mounting block.
[0010] Preferably, the T-shaped mounting block 2 has a through hole inside, and a guide rod 2 is slidably connected inside the through hole. The guide rod 2 is fixedly connected to the inner side of the gate-shaped mounting plate.

[0013] Beneficial effects:
[0014] Considering the limitation of existing technologies that cannot simultaneously cover multiple test molds onto concrete test blocks, a servo motor is operated to raise or lower multiple sets of test molds at the same time. Then, an electric push rod is operated to cause the telescopic shaft to drive the fixed frame to move up and down. This causes the rack fixedly connected inside the fixed frame to move up and down, driving the gear to rotate. This allows the gear to rotate multiple sets of test molds connected below the fixed shaft, making it easier to remove the concrete test blocks from multiple mold bases. This method of simultaneously covering multiple sets of test molds onto multiple mold bases eliminates the need for manual operation, further reducing the number of steps and improving work efficiency.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0031] This utility model provides, for example Figure 1-6 An automated testing device for concrete impermeability is shown, comprising an automated testing device body 1. A gate-shaped mounting plate 2 is connected to the outside of the automated testing device body 1 by multiple sets of bolts. A servo motor 3 is fixedly connected to the top of the gate-shaped mounting plate 2. The drive shaft of the servo motor 3 passes through the top of the gate-shaped mounting plate 2 and is welded with a one-way screw 4. A screw nut 5 is connected to the outer wall of the one-way screw 4. The screw nut 5 is fixedly connected to the inside of the protrusion of the T-shaped mounting block 6. A bearing 14 is fixedly connected to the side of the T-shaped mounting block 6. A fixed shaft 15 is connected inside the bearing 14. Multiple sets of fixed cylinders 17 are welded to the outer wall of the fixed shaft 15. A connecting column 18 is welded to the bottom of each set of fixed cylinders 17. A test mold 19 is fixedly connected to the bottom end of the connecting column 18. A mold base 25 is set below the test mold 19. There are multiple sets of mold bases 25, and the multiple sets of mold bases 25 are fixedly installed on the top of the automated testing device body 1.
[0032] Among them, the gate-shaped mounting plate 2 is used to install the servo motor 3, which drives the one-way lead screw 4 to rotate. When the one-way lead screw 4 rotates, it can drive the T-shaped mounting block 6 where the lead screw nut 5 is located to move up and down. When the T-shaped mounting block 6 moves up and down, it can drive the bearing 14 to move up and down. The bearing 14 causes the fixed shaft 15 to rotate inside it. Thus, when the bearing 14 moves up and down, it can drive the fixed shaft 15 to move up and down. The fixed shaft 15 is used to fix multiple sets of fixed cylinders 17. The fixed cylinders 17 are fixedly connected to the test molds 19 through the connecting column 18. This allows multiple sets of test molds 19 to be raised and lowered at the same time, so that they do not need to be manually lifted one by one. The test molds 19 are used to cover the mold base 25, and the mold base 25 is used to place concrete test blocks.
[0033] The T-shaped mounting block 6 has a through hole inside, and a guide rod 7 is slidably connected inside the through hole. The guide rod 7 is fixedly connected to the inside of the gate-shaped mounting plate 2.
[0034] Among them, guide rod 7 is used to guide the T-shaped mounting block 6 to move up and down, and to prevent the T-shaped mounting block 6 from deviating when it moves.
[0035] A pulley 8 is fixedly connected to the outer wall of the one-way lead screw 4. A transmission belt 9 is connected to the outside of the pulley 8. Another set of pulleys 8 is connected inside the transmission belt 9. A one-way lead screw 10 is fixedly connected inside the other set of pulleys 8.
[0036] When the pulley 8 rotates, it can drive the transmission belt 9 to drive the transmission. When the transmission belt 9 drives the transmission, it can drive another set of pulleys 8 to rotate. When the other set of pulleys 8 rotates, it can drive the one-way lead screw 10 to rotate.
[0037] The outer wall of the unidirectional lead screw 10 is connected to the lead nut 11, which is fixedly connected to the inside of the protrusion of the T-shaped mounting block 12. Another set of bearings 14 is fixedly connected to the side of the T-shaped mounting block 12.
[0038] When the unidirectional lead screw 10 rotates, it can drive the T-shaped mounting block 12 where the lead screw nut 11 is located to move up and down. This causes the T-shaped mounting block 12 and the T-shaped mounting block 6 to move up and down simultaneously, thereby driving the two sets of bearings 14 to move up and down, and thus causing the fixed shaft 15 between the two sets of bearings 14 to move up and down.
[0039] The T-shaped mounting block 212 has a through hole inside, and a guide rod 213 is slidably connected inside the through hole. The guide rod 213 is fixedly connected to the inside of the door-shaped mounting plate 2.
[0040] Among them, the guide rod 13 is used to guide the movement of the T-shaped mounting block 12 and prevent the T-shaped mounting block 12 from deviating when it moves.
[0041] A gear 16 is fixedly connected to the outer wall of the fixed shaft 15.
[0042] Among them, the gear 16 is meshed with the rack 24. When the rack 24 moves up and down, it can drive the gear 16 to rotate, which in turn drives the fixed shaft 15 to rotate. This allows the fixed shaft 15 to drive the multiple sets of test molds 19 below to flip, which makes it easier to pick up and put down the concrete test blocks on the mold base 25.
[0043] The side of the T-shaped mounting block 6 is connected to a mounting bracket 20 by multiple sets of bolts. An electric push rod 21 is fixedly connected inside the mounting bracket 20. A telescopic shaft 22 is provided inside the electric push rod 21. The top of the telescopic shaft 22 is welded to the bottom of the fixed frame 23. A rack 24 is fixedly connected inside the fixed frame 23. The rack 24 meshes with the gear 16.
[0044] The mounting bracket 20 is used to fix the electric push rod 21. The electric push rod 21 can drive the fixed frame 23 to move up and down through the telescopic shaft 22. The fixed frame 23 is equipped with a rack 24, which allows the rack 24 to move up and down, thereby driving the gear 16 to rotate.
[0045] Working principle: When using this automated concrete impermeability testing equipment, concrete test blocks are first placed one by one on multiple sets of mold bases 25. Then, the servo motor 3 is operated, causing the servo motor 3 to drive the one-way lead screw 4 to rotate. When the one-way lead screw 4 rotates, it drives the T-shaped mounting block 6, where the screw nut 5 is located, to move up and down. When the one-way lead screw 4 rotates, it drives the T-shaped mounting block 12, which moves up and down, through two sets of pulleys 8 and the conveyor belt 9. In this way, the T-shaped mounting blocks 6 and 12 descend simultaneously, thus covering multiple sets of test molds 19 on multiple sets of mold bases 25. This eliminates the need for manual operation, further reducing the operation steps and improving work efficiency.
[0046] When it is necessary to remove the concrete test blocks from multiple sets of mold bases 25, the servo motor 3 is operated again to raise the multiple sets of test molds 19. Then, the electric push rod 21 is operated to make the telescopic shaft 22 drive the fixed frame 23 to move up and down. This causes the rack 24 fixedly connected inside the fixed frame 23 to move up and down while driving the gear 16 to rotate. This allows the gear 16 to drive the multiple sets of test molds 19 connected below the fixed shaft 15 to flip over, which makes it convenient to remove the concrete test blocks from the multiple sets of mold bases 25.
[0047] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
