[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Please see the attached Figure 1 and attached Figure 2A pressure testing machine with a cleaning function includes a U-shaped frame 1, a hydraulic rod 2, a pressure detector 3, a support platform 4, a bracket 5, a clamping mechanism, a cleaning mechanism 8 and a central controller 10; the U-shaped frame 1 is a U-shaped structure, the support platform 4 is arranged in the U-shaped frame 1, and the pressure detector 3 is lifted and lowered in the U-shaped frame 1 and is located directly above the support platform 4 through the hydraulic rod 2; a pair of brackets 5 are respectively installed on both sides of the support platform 4, and a pair of clamping mechanisms are respectively installed on the pair of brackets 5, so that the concrete test block is clamped and set on the support platform 4 through the pair of clamping mechanisms; the cleaning mechanism 8 is installed on the pair of brackets 5, and the cleaning mechanism 8 can slide in contact with the surface of the support platform 4; the central controller 10 is installed on the top of the U-shaped frame 1, and the central controller 10 is electrically connected to the hydraulic rod 2, the pressure detector 3, the clamping mechanism and the cleaning mechanism 8.

[0025] Preferably, the central controller 10 can adopt a control device such as a PC to control the start, stop, movement direction, etc. of the hydraulic rod 2, pressure detector 3, clamping mechanism and cleaning mechanism 8. The function and model of the PC device can be adaptively selected according to actual control requirements.

[0026] Under the control of central controller 10, hydraulic rod 2 uses the pressure of hydraulic oil to push the piston rod downward or upward, thereby driving pressure detector 3 downward or upward. When pressure detector 3 moves downward, it applies downward pressure to the concrete test block on support platform 4. At the same time, the pressure is detected in real time and fed back to central controller 10 to meet the operational requirements of the pressure test. After the pressure test is completed, pressure detector 3 moves upward with hydraulic rod 2, away from support platform 4.

[0027] Bracket 5 is used to mount the clamping mechanism and cleaning mechanism 8. During installation, the clamping mechanism and cleaning mechanism 8 should be installed to prevent interference between their movements. The clamping mechanism is used to clamp the concrete test block from both sides, ensuring that the concrete block remains stable and does not slip during the pressure test. The cleaning mechanism 8 is used to clean concrete debris after the pressure test, eliminating the inconvenience and inefficiency of manual cleaning of concrete debris.

[0028] Please see the attached Figure 2 To the attached Figure 4 The cleaning mechanism 8 includes a first chute 801, an active motion component, a follower motion component, a scraper 805, a second chute 806 and a collection box 809; the first chute 801 and the second chute 806 are respectively installed on a pair of brackets 5 and are arranged along the two side edges of the support platform 4, the active motion component is arranged in the first chute 801, and the follower motion component is arranged in the second chute 806; the scraper 805 is connected between the active motion component and the follower motion component, and the scraper 805 is in sliding contact with the surface of the support platform 4; the collection box 809 is arranged in the U-shaped frame 1 and is located below the end of the support platform 4.

[0029] The active motion assembly provides the driving force to move the scraper 805. Driven by the scraper 805, the follower motion assembly moves synchronously with the active motion assembly, ensuring the stable movement of the scraper 805. At the same time, the scraper 805 scrapes the surface of the pallet 4 during its movement, thereby clearing concrete debris from the pallet 4. The movement of the scraper 805 pushes the concrete debris to the front of the pallet 4 and drops it into the collection box 809, replacing manual cleaning and saving time and effort.

[0030] The first chute 801 and the second chute 806 are used to install the active motion component and the follower motion component, respectively. Preferably, the top of the first chute 801 and the second chute 806 can be slightly higher than the surface of the support platform 4 to prevent concrete fragments from falling into the first chute 801 and the second chute 806 and affecting the operation of the active motion component and the follower motion component.

[0031] Please see the attached Figure 2 To the attached Figure 4 The active motion component includes a drive motor 802, a threaded rod 803 and a first transmission plate 804; the threaded rod 803 is rotatably arranged in the first slide groove 801 through a rotating bearing, and the threaded rod 803 is arranged parallel to the side edge of the support platform 4; the drive motor 802 is installed on the outer wall of one end of the first slide groove 801, and the output shaft of the drive motor 802 passes through one end of the first slide groove 801 and is coaxially fixed with the threaded rod 803; a threaded hole is formed on the first transmission plate 804 and is screwed on the threaded rod 803, and the first transmission plate 804 is slidably embedded in the first slide groove 801; one end of the scraper 805 is connected to the first transmission plate 804; the drive motor 802 is electrically connected to the central controller 10.

[0032] Preferably, the drive motor 802 can be a small motor with bidirectional rotation function, which is used to drive the threaded rod 803 to rotate in the forward or reverse direction. Since the first transmission plate 804 is slidably embedded in the first chute 804 and cannot rotate, the rotation of the threaded rod 803 is converted into linear motion of the first transmission plate 804 along the axial direction of the threaded rod 803 under the transmission of the thread. Therefore, the different rotation directions of the threaded rod 803 are used to achieve the reciprocating sliding of the first transmission plate 804 along the first chute 804, thereby driving the scraper 805 to slide forward for scraping and cleaning and slide backward for reset.

[0033] Please see the attached Figure 2 To the attached Figure 4 The follow-up motion component includes a slide rod 807 and a second transmission plate 808; the slide rod 807 is fixedly arranged in the second slide groove 806, and the second transmission plate 808 is formed with a through hole and can be slidably sleeved on the slide rod 807, so that the second transmission plate 808 is slidably embedded in the second slide groove 806; the other end of the scraper 805 is connected to the second transmission plate 808.

[0034] The diameter of the through hole on the second transmission plate 808 is slightly larger than the diameter of the slide bar 807, so that the second transmission plate 808 can slide smoothly along the axial direction of the slide bar 807 without getting stuck, achieving the purpose of following movement, and further realizing the stable movement of the scraper 805.

[0035] Please see the attached Figure 1 and attached Figure 2 The U-shaped frame 1 is provided with a protective mechanism 9, which includes a protective cover 901 and a lifting assembly. The protective cover 901 can be lifted and lowered in the U-shaped frame 1 through a pair of lifting assemblies; the protective cover 901 is a hollow box-shaped structure with an open bottom. The protective cover 901 is sleeved on the hydraulic rod 2 and can cover the four sides of the pressure detector 3 and the support platform 4.

[0036] Protective cover 901 can be made of materials such as hard metal to prevent injuries to operators from flying concrete fragments, thereby improving the safety of the pressure test. A lifting assembly controls the raising and lowering of protective cover 901. During the test, it lowers until it covers the concrete test block, pressure detector 3, and support platform 4. After the test, protective cover 901 is raised and reset.

[0037] Please see the attached Figure 1 , Attachment Figure 2 and attached Figure 5 906 , and the gear 910 is meshed with the gear 910 on the gearbox.

[0038] Preferably, the reduction motor 909 is composed of a small motor with a bidirectional rotation function and a reduction gear in the prior art, which can provide stable bidirectional rotation control for the gear 910.

[0039] When the gear 910 rotates, it can utilize the meshing transmission between the gear 910 and the tooth plate 907 to roll upward or downward along the tooth plate 907, thereby driving the protective cover 901 to achieve the lifting function through the connecting plate 903. When the reduction motor 909 is turned off, the gear 910 can be locked, so that the gear 910 is locked between the tooth plates 907 of the pair of columns 905 and prevents it from falling.

[0040] Please see the attached Figure 1 The front end surface of the protective cover 901 is embedded with explosion-proof glass 902.

[0041] Explosion-proof glass 902 can be used as an observation window, making it easy for operators to observe the test process. It is not easy to scratch or break and is highly safe.

[0042] Please see the attached Figure 2 Each group of the clamping mechanisms includes a cylinder 6 and a clamping plate 7; the cylinder 6 is arranged on the bracket 5 and is electrically connected to the central controller 10, and the piston end of the cylinder 6 is connected to the clamping plate 7, so that the clamping plate 7 is movably arranged next to the support platform 4.

[0043] Under the control of the central controller 10, the cylinder 6 uses the change of air pressure to push the piston rod to extend or retract, thereby driving the clamping plate 7 to move toward the direction close to the concrete test block to clamp the concrete test block from both sides, or move away from the concrete test block to release the concrete test block.

[0044] Please see the attached Figure 1 To the attached Figure 5 , the working process and working principle of the utility model are:

[0045] The operator places the concrete test block on the support platform 4 and starts a pair of cylinders 6 through the central controller 10. The piston rods of the pair of cylinders 6 extend to push the pair of clamps 7 toward the concrete test block, so that the pair of clamps 7 clamp the concrete test block on the support platform 4 to prevent the concrete test block from slipping during the test.

[0046] The pair of lifting assemblies move synchronously under the control of the central controller 10, so that the protective cover 901 moves downward until it covers the outside of the support platform 4 and the concrete test block; the movement mode of the pair of lifting assemblies is the same, and the following is an example of a pair of lifting assemblies:

[0047] The reduction motor 909 is started by the central controller 10, and the output shaft of the reduction motor 909 drives the gear 910 to rotate. When the gear 910 rotates, it engages with the tooth plate 907 for transmission, so that the gear 910 rolls downward along the tooth plate 907, thereby driving the protective cover 901 to move downward through the connecting plate 903 until the cover is on the outside of the support platform 4 and the concrete test block, which can prevent concrete fragments from splashing during the test.

[0048] The central controller 10 activates the hydraulic rod 2, causing it to move downward with the pressure detector 3, applying pressure to the concrete block. The pressure detector 3 detects the pressure value in real time and transmits it to the central controller 10, which displays the pressure value in real time on the display screen. The hydraulic rod 2 presses down until the concrete block breaks, concluding the pressure test on the concrete block. The concrete block pressure test process is conventional in the art and will not be detailed here.

[0049] After the test, the central controller 10 controls the cylinder 6, the reduction motor 909 and the hydraulic rod 2 to move in the opposite direction, so that the pair of clamps 7 move to the sides, the protective cover 901 moves upward, and the pressure detector 3 moves upward, all away from the support platform 4.

[0050] The central controller 10 controls the drive motor 802 to start, and the output shaft of the drive motor 802 drives the threaded rod 803 to rotate. Under the transmission of the thread, the first transmission plate 804 is moved along the first slide groove 801 and the threaded rod 803. The moving direction of the first transmission plate 804 is: from the end away from the collection box 809 to the end close to the collection box 809.

[0051] The movement of the first transmission plate 804 is transmitted to the second transmission plate 808 through the scraper 805, causing the second transmission plate 808 to slide along the second slide groove 806 and the slide rod 807, thereby causing the scraper 805 to scrape the surface of the support platform 4, pushing the concrete fragments on the support platform 4 out of the support platform 4 and dropping them into the collection box 809, completing the entire test process of a concrete specimen.

[0052] Repeat the above process to perform pressure tests on multiple concrete test blocks.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
