Description

Technical Field

[0001] This application belongs to the field of concrete testing technology, specifically relating to a pressure testing machine. Background Technology

[0002] Against the backdrop of technological upgrades and accelerated infrastructure construction in the construction industry, concrete, as a core building material, is experiencing continuous growth in both application scope and usage. With the increasing perfection of engineering quality standards and the in-depth implementation of green construction concepts, concrete performance testing has become a crucial link in ensuring building structural safety and project quality. Currently, the commonly used concrete performance testing method in the industry involves placing standard-sized cubic concrete test blocks into a concrete compression testing machine for compressive failure testing. By monitoring various data points from the moment the test block is subjected to stress to its eventual breakage, key performance indicators such as concrete strength can be obtained.

[0003] Although the aforementioned testing methods are widely used in the industry, significant technical bottlenecks still exist in practical operation. When concrete test blocks break under the load of a compression testing machine, a large amount of debris is generated, which is scattered throughout the testing site. Currently, the debris generated after the test is mainly cleaned manually, but this method is not only cumbersome and time-consuming, but also greatly reduces cleaning efficiency and has a low degree of automation. Utility Model Content

[0016] In some implementations, the receiving component includes a retaining plate and a receiving trough, the receiving trough being the area formed between the retaining plate and the edge of the pressing member, and a discharge plate is provided on one side of the retaining plate.

[0017] In some implementations, the height of the pressing member is less than the height of the enclosure.

[0018] In some implementations, the pressing mechanism further includes a sweeping component, which is movably connected to the edge of the pressing member and is disposed opposite to the receiving trough.

[0019] In some implementations, the edge of the upper pressure member is provided with a guide rail;

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0035] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0036] Example 1:

[0037] Please see the appendix Figure 1-2 The pressure testing machine of this application includes a frame 1, an upper pressing mechanism 2, and a lower pressing mechanism 3. The upper pressing mechanism 2 includes a first driving member 21, an upper pressing member 22, and a cleaning member 23. The first driving member 21 is driven and connected to the upper pressing member 22 and mounted on the frame 1. The upper pressing member 22 has a groove 221, and the cleaning member 23 is movably connected to the groove 221. The lower pressing mechanism 3 includes a lower pressing member 31 and a collecting member 32. The lower pressing member 31 is disposed opposite to the upper pressing member 22, and the collecting member 32 surrounds the edge of the lower pressing member 31 to collect debris. During the pressure test, the cleaning member 23 is embedded in the groove 221 and coplanar with the upper pressing member 22 for pressing; during the cleaning process, the cleaning member 23 protrudes from the groove 221 and rotates to remove debris.

[0038] The frame 1 is the supporting structure that bears all functional components, and can be implemented using a steel frame structure, providing a rigid mounting reference for the upper and lower pressing mechanisms 3. The upper pressing component 22 is a flat plate that applies pressure, and can be implemented using an alloy steel plate with guide columns. Its groove 221 is used to accommodate the cleaning component 23. The cleaning component 23 is a movable component with cleaning function, and can be implemented using a combination of a rotating scraper and a lifting mechanism, achieving shape transformation within the groove 221. The lower pressing component 31 is a platform that carries the test block, and can be implemented using a cast iron platform with positioning grooves, forming a pressure working surface with the upper pressing component 22. The collecting component 32 is a debris collection device, and can be implemented using a combination of an annular surrounding plate 321 and a guide channel, constraining the debris dispersion range.

[0039] Specifically, during the pressure test, the cleaning component 23 is fully embedded in the groove 221 of the upper pressure member 22, flush with the bottom surface of the upper pressure member 22, forming a complete pressure application plane. The first driving component 21 drives the upper pressure member 22 to press down, applying uniform pressure to the concrete specimen. After the test, the cleaning component 23 protrudes from the groove 221, and peels off the debris adhering to the surface of the lower pressure member 31 through a rotational motion. The peeled debris is blocked by the retaining plate 321 of the collecting component 32 and collected along the guide path. After cleaning, the cleaning component 23 retracts into the groove 221 to reset, ready for the next test. The entire process, through the changing shape of the cleaning component 23, ensures both test accuracy and in-situ cleaning of debris.

[0040] In this embodiment, the pressure testing machine uses a retractable and rotatable cleaning component 23 to remove debris inside the equipment, achieving automated integration of testing and cleaning processes, avoiding manual intervention, and eliminating downtime caused by manual cleaning. The annular enclosure design of the receiving component 32 replaces the open workbench, effectively preventing debris from splashing. The embedded structure of the cleaning component 23 avoids interference from external cleaning tools in the testing process, achieving functional integration. Through the above settings, the debris cleaning process is integrated into the equipment's operating cycle, saving time and effort in cleaning operations, reducing manual labor intensity, achieving a high degree of automation, significantly improving cleaning efficiency, ensuring the continuity of testing operations, effectively ensuring a clean testing environment, and further ensuring the accuracy of pressure testing.

[0041] Please refer to Appendix 3. This application further proposes a cleaning component 23 including a cleaning element 231, a connecting element 232, a rotary motor 233, and a first cylinder 234. The cleaning element 231 is used to remove debris from the surface of the pressing element 31; the connecting element 232 is connected to the middle position of the cleaning element 231; the drive end of the rotary motor 233 is connected to the connecting element 232; and the drive end of the first cylinder 234 is connected to the rotary motor 233.

[0042] The cleaning component 231 refers to the debris removal tool that directly contacts the surface of the pressing component 31. It can be implemented using a metal scraper or a hard plastic brush structure, and is used to peel away concrete debris adhering to the surface of the pressure mechanism through rotational motion. The connecting component 232 refers to the intermediate component that transmits rotational power. It can be implemented using a coupling or a rigid connecting rod structure, and its connection with the middle of the cleaning component 231 can balance the torque distribution during rotation. The rotary motor 233 refers to the power source that drives the cleaning component 231 to generate rotational motion. It can be implemented using a stepper motor or a servo motor, and can effectively remove different amounts of debris by precisely controlling the rotational speed. The first cylinder 234 refers to the actuator that controls the lifting and lowering of the cleaning component 231. It can be implemented using a double-acting cylinder structure, and can switch the cleaning component 231 between the pressing plane and the cleaning position through stroke control.

[0043] Specifically, during the pressure test, the first cylinder 234 drives the rotary motor 233 to move downwards, causing the cleaning component 231 to be fully embedded in the groove 221 of the upper pressure component 22. At this time, the upper surface of the cleaning component 231 is flush with the working surface of the upper pressure component 22, ensuring uniform force distribution when pressure is applied. When the test block breaks and needs cleaning, the first cylinder 234 drives the rotary motor 233 and the connecting component 232 to rise, causing the cleaning component 231 to protrude a predetermined distance from the groove 221. The rotary motor 233 then starts to drive the cleaning component 231 to rotate around its axis, sweeping the residual debris on the surface of the lower pressure component 31 into the collection area through centrifugal force and scraping action. This switching of working modes is achieved through the linkage control of the cylinder and the motor, and the function switching can be completed without manual intervention.

[0044] This solution integrates a lifting and rotating cleaning mechanism to automatically complete the cleaning operation during the testing machine's working cycle. The cleaning action covers the entire surface of the pressing component 31, and the linear velocity of the rotating cleaning component 231 can be adapted to different aggregate bonding strengths. This design solves the problems of low efficiency and insufficient automation in cleaning aggregates after concrete block breakage. The rotating scraping action of the cleaning component 23 effectively removes aggregates of different particle sizes, and the cylinder-driven lifting control allows the equipment to automatically switch between pressing and cleaning modes. Compared to manual cleaning, this reduces downtime and avoids the safety risks of operators coming into contact with broken test blocks.

[0045] Please see the appendix Figure 3 This application further proposes that the receiving component 32 includes a surrounding plate 321 and a receiving trough 322, the receiving trough 322 being the area formed between the edges of the surrounding plate 321 and the pressing member 31, and a discharge plate 323 is provided on one side of the surrounding plate 321.

[0046] Specifically, during the pressure test, the debris generated on the surface of the pressing component 31 falls naturally into the collection trough 322 due to gravity. The closed structure formed by the surrounding plate 321 effectively prevents the debris from splashing in all directions. The annular space of the collection trough 322 confines the debris within a predetermined area, preventing it from scattering randomly. When the debris accumulates to a certain amount, the operator discharges the debris from the discharge plate 323, realizing the debris discharge function and ensuring the continuity of debris collection.

[0047] Through the above technical solution, this application realizes the real-time collection and centralized discharge of debris during the test, avoiding the inefficiency caused by manual cleaning. The receiving trough 322 can hold more debris, effectively reducing the number of cleaning times.

[0048] This application further proposes that the height of the pressure member 31 is less than the height of the enclosure 321.

[0049] The surrounding plate 321 refers to the vertical baffle plate surrounding the edge of the pressing member 31. Specifically, it is made of 304 stainless steel with a thickness of 2-3mm, bent and formed, and fixed to the base of the pressing mechanism 3 by welding or bolting, forming a continuous blocking structure higher than the bearing surface. The height difference between the two is controlled within the range of 10-30mm to ensure that an effective blocking line is formed at the top of the surrounding plate 321.

[0050] Specifically, when the concrete test block breaks under pressure, the splashed debris spreads outward due to inertia. The surrounding plate 321, due to its height advantage, forms a ring-shaped barrier wall, physically confining the debris within the receiving space formed by the surface of the lower pressure member 31 and the inner wall of the surrounding plate 321. During subsequent cleaning operations, this three-dimensional receiving space created by the height difference can temporarily store the debris, preventing airflow disturbances during cleaning from causing it to overflow. Simultaneously, the continuous flange formed at the top of the surrounding plate 321 maintains a safe distance from the upper pressure mechanism 2, ensuring that the equipment operation is not interfered with.

[0051] This solution creates a collection cavity with three-dimensional blocking capabilities by constructing a height difference between the enclosure 321 and the bearing surface. Under the same working conditions, the amount of debris escaping can be reduced to less than 20% of the original design, without the need for additional power devices. This effectively solves the problem of debris scattering from the edge of the lower pressure component 31 and achieves automatic closed collection of debris during the test. After the debris is completely confined inside the collection trough 322, it is then centrally cleaned, avoiding secondary pollution during manual cleaning and reducing the frequency of equipment maintenance.

[0052] Example 2:

[0053] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 4 In this embodiment, the pressing mechanism 2 also includes a sweeping component 24, which is movably connected to the edge of the pressing component 22 and is disposed opposite to the receiving trough 322.

[0054] Specifically, when the pressure test is completed, the cleaning component 23 sweeps the debris from the lower pressing component 31 into the receiving trough 322. Under the action of the driving device, the upper pressing component 22 brings the bottom of the sweeping component 24 into contact with the surface of the receiving trough 322, and moves along the edge of the upper pressing component 22. During this movement, the debris scattered in the area of ​​the receiving trough 322 is continuously pushed and swept towards the discharge plate 323. Because the movement trajectory of the sweeping component 24 covers the entire width of the receiving trough 322, it ensures that debris in all locations within the trough is effectively cleaned. This process is entirely automated by the mechanical transmission mechanism, requiring no manual intervention.

[0055] Through the above technical solution, this application can automatically complete the centralized cleaning of test debris, avoiding the inefficiency caused by manual cleaning. The cleaning action is synchronized with the equipment's working cycle, and the debris is immediately cleaned out of the working area after the test, ensuring that the continuous operation of the equipment is not affected by debris accumulation. The cooperative design of the cleaning components and the receiving chute 322 allows the debris to move in a directional manner to the designated discharge port, preventing secondary pollution.

[0056] This application further proposes that the edge of the upper pressing member 22 is provided with a guide rail 222, and the sweeping member 24 includes a slider 241, a sweeping member 242 and a second driving member 243. The second driving member 243 drives the slider 241 to slide on the guide rail 222, the sweeping member 242 is connected to the slider 241, and the sweeping member 242 is arranged opposite to the receiving groove 322.

[0057] Among them, the guide rail 222 refers to the guide structure installed on the edge of the upper pressure member 22. Specifically, it can be implemented by using aluminum alloy profile rails or steel slide rails to limit the movement trajectory of the sweeping member 242.

[0058] The second driving component 243 refers to the power output device, which can be implemented by a servo motor or a stepper motor, and drives the slider 241 to move through a gear rack or synchronous belt transmission method.

[0059] The sweeping component 242 refers to the actuating component with a sweeping function, which can be implemented by a metal scraper or a nylon brush body structure, and its length covers the width direction of the receiving trough 322.

[0060] Specifically, after the pressure test, the second drive unit 243 starts and drives the slider 241 to reciprocate linearly along the guide rail 222. Simultaneously, the sweeping component 242, fixed on the slider 241, moves to the receiving trough 322 area. The bottom surface of the sweeping component 242 remains in contact with the surface of the pressing component 31, and through continuous displacement, pushes the concrete debris scattered in the receiving trough 322 towards the discharge plate 323. The trajectory of the guide rail 222 ensures that the movement path of the sweeping component 242 completely coincides with the length direction of the receiving trough 322, avoiding blind spots in cleaning. The motion parameters of the second drive unit 243 can be programmed through the control system to achieve single or multiple cycle cleaning modes.

[0061] This solution, through the cooperation of guide rail 222 and drive mechanism, enables the sweeping component 242 to automatically complete the debris cleaning operation in the entire receiving trough 322 area without manual intervention. This solves the problem of low efficiency caused by manual cleaning of debris during concrete pressure testing and achieves automated cleaning operation. Furthermore, the movement of the sweeping component 242 along a predetermined trajectory ensures that debris in the receiving trough 322 is thoroughly removed, forming a continuous material discharge channel with the discharge plate 323. The programmed control of the drive mechanism allows the cleaning frequency to be flexibly adjusted according to the amount of debris, improving the intelligence level of equipment operation.

[0062] This application further proposes that the sweeping component 242 and the receiving component 32 are provided with a nylon broom on the opposite side, and the nylon broom is used to sweep up debris.

[0063] The nylon broom refers to a bristle structure formed by weaving nylon monofilaments with a diameter ranging from 0.2 to 0.5 mm. Specifically, it can be achieved by injection molding thermoplastic polyamide material and fixing it to the broom component 242 substrate. The bristle density is controlled within the range of 30-50 bristles per square centimeter. This structure reduces the risk of mechanical damage to the equipment surface through flexible contact.

[0064] Specifically, the nylon bristle broom forms flexible contact with the surface of the pressing component 31 during the reciprocating motion of the sweeping component 242. Its densely arranged bristles can cover a cleaning area with a width ranging from 70 to 150 mm. When the sweeping component 242 slides along the guide rail 222, the nylon bristle broom contacts the debris accumulation surface at an inclined angle, and the contact pressure generated by the elastic deformation of the bristles pushes the debris particles to the discharge plate 323. During the cleaning process, the debris is continuously pushed towards the discharge plate 323, and the low coefficient of friction of the nylon material reduces secondary scattering during the pushing process.

[0065] This embodiment of the nylon broom improves cleaning efficiency to over 85% through flexible contact, while avoiding damage to the equipment surface and controlling the amount of residual debris to less than 5 grams per square meter. This design achieves fully automated debris removal, with the nylon broom covering over 98% of the effective working area in a single cleaning operation, reducing the cleaning cycle to less than 30 seconds. This structure eliminates the need for operators to directly contact debris, reducing labor intensity by approximately 70% and decreasing the wear rate of key equipment components by 40%.

[0066] Please see the appendix Figure 4 This application further proposes that the receiving trough 322 is recessed to form a dropping trough 324 corresponding to the discharge plate 323, and the dropping trough 324 is connected to the discharge plate 323.

[0067] Among them, the material discharge trough 324 refers to the recessed structure located at the connection between the material receiving trough 322 and the discharge plate 323. Specifically, it can be formed by mechanical stamping or casting process. The recessed structure can guide the slag to move in the discharge direction under the action of gravity.

[0068] Among them, the discharge plate 323 refers to the inclined guide plate set on one side of the enclosure plate 321. Specifically, it can be installed by welding metal plates or fixing with bolts, and is used to discharge the slag from the discharge chute 324 to the external collection container.

[0069] Specifically, during the cleaning process, the sweeping component 24 moves along the edge of the pressing component 31 and sweeps the debris to the discharge trough 324. Since the discharge trough 324 has a concave structure, the debris slides along the inclined bottom of the trough towards the discharge plate 323 under gravity, and is finally discharged through the discharge plate 323. The interconnected design of the discharge trough 324 and the discharge plate 323 forms a continuous flow channel, preventing debris from accumulating at the edge of the receiving trough 322 and ensuring that no debris remains during the process from the receiving trough 322 to the discharge plate 323.

[0070] This solution utilizes the recessed structure of the material chute 324 to connect with the discharge plate 323, allowing the debris to automatically slide to the external collection point during the cleaning process without manual intervention. This achieves directional flow of debris from the collection chute 322 to the discharge plate 323, solving the problems of residue and low discharge efficiency during debris collection. The debris is automatically discharged during the cleaning process, eliminating the need for machine shutdown and improving equipment operational continuity.

[0071] This application further proposes that the sweeping component 24 also includes a second cylinder 244, the driving end of the second cylinder 244 is connected to the sweeping component 242, and the mounting end of the second cylinder 244 is connected to the slider 241.

[0072] The second cylinder 244 is an actuator that generates linear motion power by compressing gas. Specifically, it can be implemented by a single-rod double-acting cylinder. Its drive end is connected to the sweeping component 242, which can adjust the pressure or height position of the sweeping component 242.

[0073] Among them, slider 241 refers to a mechanical component that moves linearly along guide rail 222. Specifically, it can be implemented by using an aluminum alloy slider 241 with ball bearings. It cooperates with guide rail 222 to realize the translational movement of sweeping component 242, and at the same time serves as the mounting base for second cylinder 244.

[0074] Specifically, the drive end of the second cylinder 244 is rigidly connected to the sweeping component 242. When the cylinder piston rod extends or retracts, it can drive the sweeping component 242 to move in a direction perpendicular to the guide rail 222. When debris accumulates in the collection trough 322, the second cylinder 244 can push the sweeping component 242 downward to increase the contact pressure between the nylon bristle broom and the debris. When it is necessary to adjust the cleaning range, the slider 241 slides along the guide rail 222 to drive the sweeping component 242 to move laterally. The combination of the second cylinder 244 and the slider 241 allows the sweeping component 242 to adjust its vertical position simultaneously during horizontal movement, thereby adapting to the cleaning needs of debris layers of different thicknesses.

[0075] In some specific embodiments, a pressure sensor can be installed between the sweeping component 242 and the second cylinder 244 to monitor the contact pressure value of the sweeping component 242 on the debris in real time. When the pressure exceeds a set threshold, the cylinder automatically retracts to avoid excessive wear of the nylon bristle broom. A limit switch can be installed at the end of the guide rail 222, which automatically triggers the cylinder to reset when the slider 241 moves to the end of the rail.

[0076] This solution utilizes the linkage control between the cylinder and the slider 241 to enable the sweeping component 242 to dynamically adjust vertically during translation. This avoids equipment damage caused by rigid contact and allows for real-time adjustment of cleaning parameters based on the distribution of debris. This design achieves multi-dimensional motion control of the sweeping component 242 during cleaning. The nylon bristle broom moves in contact with the debris surface with constant pressure, ensuring cleaning coverage while preventing debris from splashing, significantly improving the automation level of debris cleaning.

[0077] Example 3:

[0078] The difference between this embodiment and Embodiment 2 is that, please refer to... Figure 5 The pressure testing machine in this embodiment also includes a protective cover 4, which is hinged to the frame 1 and is used to block flying stones during the pressure testing operation.

[0079] Among them, the hinge connection refers to the rotatable mechanical connection between the protective cover 4 and the frame 1, which can be achieved by using a hinge or shaft structure, so that the protective cover 4 has the function of opening and closing, which not only ensures a safe working area during the test, but also facilitates opening and operation during equipment maintenance.

[0080] Specifically, during the pressure test, the protective cover 4 is in a closed state, forming a physical barrier to prevent debris from the broken test block from splashing outwards. When it is necessary to replace the test block or maintain the equipment, the protective cover 4 can be rotated open via a hinge structure to provide sufficient space for operation. After the test, the closed protective cover 4 confines the debris within the equipment's working area, preventing debris from scattering to the surrounding area.

[0081] This solution uses protective cover 4 to limit the spread of debris to the internal area of ​​the equipment, significantly reducing the effective area for cleaning operations, while preventing high-speed flying debris from posing safety hazards to operators and improving the safety of equipment use.
