Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically to a device for testing the compressive strength of building concrete. Background Technology

[0002] Concrete is the most widely used and consumed basic building material in modern construction engineering. Its quality is directly related to the structural safety, durability and service life of buildings. Among the various performance indicators of concrete, compressive strength is one of the most critical mechanical performance parameters. It not only reflects the load-bearing capacity of concrete, but is also an important basis for structural design, construction quality control and project acceptance.

[0003] The patent with publication number CN218098658U discloses a device for testing the compressive strength of building concrete, including a supporting base box. The other end of the pressure sensor is connected to a fixed base, and the fixed base is provided with connecting guide rods on both sides. The connecting guide rods are provided with guide blocks, and the upper end of the guide blocks is provided with hydraulic rods. The other end of the hydraulic rods is provided with hydraulic motors, and the other side of the hydraulic motors is provided with connecting wires. The hydraulic motors are electrically connected to the controller through the connecting wires. The lower end of the guide blocks is provided with a pressure plate, and the pressure plate is connected to the connecting guide rods in a sliding lifting connection through a groove, a ball bearing, and a hydraulic rod.

[0004] However, the aforementioned device has the following problems when in use: First, the equipment lacks an effective protective mechanism. When conducting a pressure destructive test on a concrete specimen, the specimen breaks instantly, generating a large amount of debris and particles that are easily scattered at high speed in all directions. This not only seriously pollutes the testing environment and increases the difficulty of cleaning, but may also cause physical injuries to operators (such as eye or skin abrasions), posing a significant safety hazard and failing to meet the requirements of modern laboratory safety standards.

[0005] Secondly, since the equipment is not equipped with an automatic chip removal or dust collection system, the testing process must be paused after each pressure test, and the concrete fragments and powder remaining on the pressure table and test block support area must be cleaned manually. This cleaning process is time-consuming and requires close intervention from operators, affecting the continuity and overall efficiency of the testing work. Utility Model Content

[0006] The purpose of this invention is to solve the problems existing in the prior art by proposing a device for testing the compressive strength of building concrete, which achieves an organic unity of safety protection, efficient cleaning and continuous testing capabilities.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A device for testing the compressive strength of building concrete includes a body, a controller mounted on the body, a bracket fixedly mounted on the body, a hydraulic module mounted on the bracket, a contact pressure plate mounted on the side of the hydraulic module facing the body, a fixed platform fixedly mounted on the body, a rotating placement plate mounted on the fixed platform, a waste collection box corresponding to the inclined end of the rotating placement plate mounted on the body, a connecting rod fixedly mounted on the bracket, a fixed plate fixedly mounted on the connecting rod, a shielding accordion fixedly mounted on the side of the fixed plate away from the connecting rod, a movable frame fixedly mounted at the bottom of the shielding accordion, and a drive mechanism mounted on the bracket.

[0009] Preferably, the fixed platform is fixedly installed with two fixed blocks, and a rotating rod is rotatably installed between the two fixed blocks. The rotating rod is fixedly connected to the rotating placement plate.

[0010] Preferably, the driving mechanism includes two multi-stage telescopic rods, one end of each multi-stage telescopic rod is mounted on a bracket, and a connecting block is installed at the output end of each of the two multi-stage telescopic rods. The connecting block is fixedly connected to the movable frame.

[0011] Preferably, driving rods are fixedly installed on both the left and right sides of the movable frame, and toothed plates are fixedly installed on the ends of the two driving rods away from the movable frame. Both ends of the rotating rod pass through corresponding fixed blocks and are fixedly installed with gears, and the gears are meshed with the corresponding toothed plates.

[0012] Preferably, a shielding frame is fixedly installed on the rotating placement plate, the shielding frame is n-shaped, and one side of the inclined end of the rotating placement plate is not sealed.

[0013] Preferably, the machine body has a slot at a corresponding position for accommodating the corresponding drive rod.

[0014] Preferably, the fixing plate has holes adapted to the hydraulic module, and the contact pressure plate is always inside the bellows cover.

[0015] Preferably, the side of the movable frame away from the fixed plate can directly abut against the upper surface of the rotating placement plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention features a bellows cover that completely encloses the test block during testing, creating a sealed space. This, combined with the downward pressure of the moving frame against the placement plate, forms a double seal, eliminating the risk of debris splashing when concrete collapses and significantly improving operational safety. After testing, the bellows cover rises, triggering a linkage mechanism that, through precise meshing of the toothed plate and gears, automatically tilts the placement plate, concentrating the debris into the waste collection bin. Combined with an automatic reset function, this allows for rapid waste removal and resetting, significantly improving testing efficiency. Overall, it achieves a unified approach to safety protection, efficient cleaning, and continuous testing capabilities. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figures 1 to 7 A device for testing the compressive strength of building concrete includes a body 1, a controller 2 mounted on the body 1, a bracket 3 fixedly mounted on the body 1, a hydraulic module 4 mounted on the bracket 3, and a contact pressure plate 11 mounted on the side of the hydraulic module 4 facing the body 1.

[0028] The operator first places the concrete test block to be tested on the rotating placement plate 9 of the fixed platform 8. Then, the equipment is started via the controller 2. The controller 2 controls the hydraulic module 4 on the support 3 to start. The hydraulic module 4 drives the contact pressure plate 11 below it to move downward, applying continuously increasing pressure to the concrete test block placed on the rotating placement plate 9 until the test block is crushed. The machine body 1 is the basic structure of the entire device, supporting all other components. Since this part is prior art and has been disclosed sufficiently, it will not be described in detail here.

[0029] A fixed platform 8 is fixedly installed on the machine body 1. A rotating placement plate 9 is provided on the fixed platform 8. A waste collection box 10 corresponding to the inclined end of the rotating placement plate 9 is provided on the machine body 1. The fixed platform 8 provides a platform for placing and fixing test blocks. The rotating placement plate 9 is used to support the test blocks and can be tilted after the test is completed to pour the test block debris into the waste collection box 10 for easy cleaning.

[0030] A connecting rod 5 is fixedly installed on the bracket 3, a fixing plate 6 is fixedly installed on the connecting rod 5, a pleated cover 7 is fixedly installed on the side of the fixing plate 6 away from the connecting rod 5, a movable frame 12 is fixedly installed at the bottom of the pleated cover 7, and a drive mechanism is provided on the bracket 3.

[0031] The connecting rod 5 and the fixing plate 6 fix the shielding accordion cover 7 to the bottom of the bracket 3. The shielding accordion cover 7 is a retractable protective cover, and its bottom is fixed on the moving frame 12. When the drive mechanism is running, it will drive the moving frame 12 to move up and down, thereby making the shielding accordion cover 7 extend and retract. During the test, the shielding accordion cover 7 extends downward to cover the test block, preventing debris from flying when the test block is crushed, thus protecting the safety of the operator and the cleanliness of the environment.

[0032] like Figure 6 , Figure 7 As shown, the fixed platform 8 is fixedly installed with two fixed blocks 18, and a rotating rod 19 is rotatably installed between the two fixed blocks 18. The rotating rod 19 is fixedly connected to the rotating placement plate 9. The fixed blocks 18 are firmly installed on the fixed platform 8 to provide support bearings for the rotating rod 19. The rotating rod 19 passes through the two fixed blocks 18 and is constrained by them, so that it can only perform rotational movement.

[0033] like Figure 4 As shown, the drive mechanism includes two multi-stage telescopic rods 13. One end of each multi-stage telescopic rod 13 is mounted on the bracket 3. Each output end of the two multi-stage telescopic rods 13 is equipped with a connecting block 14, which is fixedly connected to the movable frame 12.

[0034] The core of the drive mechanism consists of two multi-stage telescopic rods 13 (usually hydraulic cylinders or electric push rods). One end of each rod is fixed at the top of the bracket 3. When it is necessary to lower the bellows cover 7 for protection or raise the bellows cover 7 for cleaning, the controller 2 will activate the multi-stage telescopic rods 13. The output end of the multi-stage telescopic rods 13 extends downward (or upward) (or retracts), and drives the movable frame 12, which is fixedly connected to it, to move vertically up and down through the connecting block 14. Since the principle of the multi-stage telescopic rods 13 and the corresponding installation structure are existing technologies, they will not be described in detail here.

[0035] It is worth noting that corresponding equipment is needed to ensure the synchronization of the movement of the two multi-stage telescopic rods 13. Since this is existing technology, it will not be elaborated here.

[0036] like Figure 4 As shown, driving rods 15 are fixedly installed on both the left and right sides of the movable frame 12. A toothed plate 16 is fixedly installed on one end of the two driving rods 15 away from the movable frame 12. Both ends of the rotating rod 19 pass through the corresponding fixed block 18 and are fixedly installed with gears 20. The gears 20 are meshed with the corresponding toothed plates 16.

[0037] The lifting and lowering motion of the movable frame 12 is transmitted to the toothed plate 16 through the drive rod 15. When the movable frame 12 is driven to descend by the multi-stage telescopic rod 13, the drive rod 15 and the toothed plate 16 also descend. At this time, the toothed plate 16 is always below the gear 20 and will not come into contact with it.

[0038] When the moving frame 12 rises, the driving rod 15 rises synchronously. Initially, the toothed plate 16 does not contact the gear 20. When the moving frame 12 is about to reach the end, the toothed plate 16 contacts the gear 20. Since the toothed plate 16 meshes with the gear 20 fixed at the end of the rotating rod 19, the upward movement of the toothed plate 16 will drive the gear 20 to rotate. Because the left and right sides are synchronously linked (two multi-stage telescopic rods 13, two toothed plates 16, and two gears 20), the rotating rod 19 will rotate smoothly, thereby driving the rotating placement plate 9 to tilt from the horizontal position towards the waste collection box 10, completing the initial dumping of waste. The operator can use a brush for further cleaning.

[0039] After the tilting is completed, the drive mechanism causes the moving frame 12 to descend a certain distance, causing the toothed plate 16 to separate from the gear 20. Under the action of meshing and gravity, the rotating placement plate 9 and the fixed platform 8 come into contact. At this time, there is still space between the rotating placement plate 9 and the moving frame 12 for the test block to be placed, so that the next test block placement activity can be carried out quickly.

[0040] like Figure 6 , Figure 7 As shown, a shielding frame 17 is fixedly installed on the rotating placement plate 9. The shielding frame 17 is n-shaped, and one side of the inclined end of the rotating placement plate 9 is not sealed.

[0041] The shielding frame 17 is an "n"-shaped frame fixed to the upper surface of the rotating placement plate 9. Its main function is to form a protective space when the shielding accordion cover 7 is raised, preventing debris from falling from other sides of the rotating placement plate 9. When the rotating placement plate 9 needs to be tilted to unload, its unsealed side (facing the waste collection box 10) serves as the outlet for debris.

[0042] like Figure 7 As shown, the body 1 has an insertion slot 21 at the corresponding position to accommodate the corresponding drive rod 15.

[0043] The insertion slot 21 is a vertical slot opened on the side wall of the body 1 or near the fixed platform 8. Its function is to provide the necessary space channel for the vertical movement of the drive rod 15, and to ensure that the drive rod 15 is not blocked by the structure of the body 1 during the process of driving the moving frame 12 to rise and the rotating placement plate 9 to rotate, so that the movement is smooth and without interference.

[0044] Preferably, a corresponding protective structure (such as a cover) can be provided at the contact point between the toothed plate 16 and the gear 20 to ensure the stability of the meshing.

[0045] like Figure 2 , Figure 4 As shown, the fixed plate 6 has holes adapted to the hydraulic module 4, and the contact plate 11 is always inside the bellows cover 7.

[0046] The fixed plate 6 has a hole in its center, the size of which allows the piston rod of the hydraulic module 4 to pass through. This design ensures that when the bellows cover 7 is raised to its highest position by the moving frame 12, the contact plate 11 remains inside the bellows cover 7. This means that throughout the entire test cycle (pressurization, pressure holding, and unloading) and during the raising and lowering of the bellows cover 7, the contact plate 11 is always within the protection range of the bellows cover 7, preventing any debris that might splash from the plate area from escaping and improving safety.

[0047] like Figure 1 , Figure 2As shown, the side of the movable frame 12 away from the fixed plate 6 can directly abut against the upper surface of the rotating placement plate 9, ensuring that the debris will not fly and can be concentrated inside the space for easy subsequent processing.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
