DETAILED DESCRIPTION
[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] Example:
[0029] like Figures 1 to 7 As shown, a concrete pressure testing machine with a debris cleaning function includes a base 6 and a debris cleaning mechanism 4. A pressure test bench 5 is fixedly provided on the upper side of the base 6. Columns 3 are fixedly provided at the four corners of the upper end surface of the base 6. The upper ends of the columns 3 are fixedly connected to an upper crossbeam 2. A screw 1 is screwed inside the upper crossbeam 2. An upper pressure plate 7 is assembled at the lower end of the screw 1. A debris cleaning mechanism 4 is provided on the outside of the pressure test bench 5.
[0030] In this embodiment, the debris cleaning mechanism 4 includes a baffle cover 41, a slag discharge guide pipe 42, a lifting assembly 43, a translation assembly 45 and a push plate 46. The baffle cover 41 is arranged on the outside of the pressure test bench 5, and a translation assembly 45 is provided inside the baffle cover 41. A movable back plate 411 is provided on the inside of the translation assembly 45, and a push plate 46 is fixedly provided on the front side of the back plate 411. The lower side of the front end surface of the baffle cover 41 is fixedly connected to the slag discharge guide pipe 42, and a slag collecting box 44 is placed on the base 6 just below the slag discharge guide pipe 42. A lifting assembly 43 is provided on the lower side of the baffle cover 41. This design solves the problem that the existing concrete pressure testing machine usually needs to manually clean up the debris left after the test, which is not only time-consuming and labor-intensive, but may also cause harm to the operator, and the operation is cumbersome and inefficient. In addition, incomplete debris cleaning will affect the accuracy of subsequent tests.
[0031] The test machine utilizes an integrated debris cleaning mechanism 4, including a containment cover 41, a slag discharge guide tube 42, a lifting assembly 43, a translation assembly 45, and a push plate 46, to automatically collect and clean debris, significantly saving time and labor associated with manual cleaning and improving post-test cleaning efficiency. Furthermore, the debris cleaning mechanism 4 allows for timely cleaning of debris after the test, preventing residual debris from interfering with subsequent tests and ensuring a clean test environment, thereby improving test accuracy and reliability. Furthermore, the automatic cleaning function reduces direct contact between the operator and the debris, reducing the risk of injury from manual debris cleaning and improving work safety.
[0032] In this embodiment, the lifting assembly 43 includes a drive motor 431, a first screw rod 434, and a base plate 435. The base plate 435 is arranged on the enclosure cover 41 and is fixedly connected to the pressure test bench 5. Rotatable first screw rods 434 are installed at the two front corners of the base plate 435. The drive motor 431 is installed at the bottom of the base plate 435, and the output end of the drive motor 431 is fixedly connected to the lower end of the first screw rod 434 on the right side. First ear plates 437 are fixed to the front sides of the left and right ends of the enclosure cover 41. The first screw rod 434 passes through the first ear plates 437 and is screwed thereto. Both sets of first screw rods 434 are equipped with first pulleys 433, and the two sets of first pulleys 433 are connected by a first belt 432. The lifting assembly 43 can drive the enclosure cover 41 to move up and down, and can lower the enclosure cover 41 when placing concrete specimens, so as to prevent the pressure test bench 5 from being obstructed. When the drive motor 431 is started, its output shaft rotates the right-side first threaded screw 434. Since the two sets of first threaded screws 434 are connected via the first belt 432 and the first pulley 433, the left-side first threaded screw 434 also rotates synchronously. As the first threaded screws 434 rotate, the first lugs 437 on the front sides of the left and right ends of the enclosure cover 41 move up and down along the screws, driven by the threads. Since the two sets of screws rotate synchronously and in the same direction, the enclosure cover 41 can achieve smooth lifting and lowering motion.
[0033] In this embodiment, support rods 436 are fixed to the two corners of the upper end surface of the bottom plate 435 near the rear side. Second ear plates 438 are fixed to the rear sides of the left and right end surfaces of the enclosure cover 41. The support rods 436 pass through the second ear plates 438 and slideably connect them. The support rods 436 provide guidance and support for the raising and lowering of the enclosure cover 41, ensuring that the enclosure cover 41 remains stable during the raising and lowering process.
[0034] In this embodiment, the translation assembly 45 includes a second threaded rod 451, a second pulley 452, a second belt 453, and a motor 454. Two sets of second threaded rods 451 are symmetrically arranged on the left and right sides of the enclosure 41. The second threaded rods 451 are rotatably connected to the enclosure 41 via bearings. The rear ends of both sets of second threaded rods 451 extend through the enclosure 41 and are each equipped with a second pulley 452. The two sets of second pulleys 452 are connected by a second belt 453. The rear end of one set of second threaded rods 451 is fixedly connected to the output end of the motor 454. This design, through the translation assembly 45, drives the push plate 46 to move horizontally along the upper end surface of the pressure test bench 5. The push plate 46 then pushes debris scattered from the upper end surface of the pressure test bench 5 forward, allowing the debris to be pushed to the slag discharge guide pipe 42 for cleaning. When the motor 454 is started, its output shaft drives the second threaded rods 451 connected thereto to rotate. Because the two sets of second threaded screws 451 are connected via a second belt 453 and a second pulley 452, the other set of second threaded screws 451 also rotates synchronously. As the second threaded screws 451 rotate, the back plate 411 and its push plate 46, driven by the threads, translate along the screws, achieving smooth translational motion. During this translation, the push plate 46 pushes the slag from the pressure test bench 5 to the slag discharge conduit 42, which then guides the slag to the slag collection box 44 below for collection and subsequent processing.
[0035] In this embodiment, sleeves 48 are fixed to both sides of the back plate 411. Sleeves 48 are sleeved over and threadedly connected to the second threaded rod 451. Sleeves 48 serve as connecting components to the second threaded rod 451, responsible for converting the rotational motion of the second threaded rod 451 into translational motion of the push plate 46. When the second threaded rod 451 rotates, the sleeves 48 can move along the axis of the rod, thereby driving the back plate 411 and the push plate 46 to translate.
[0036] In this embodiment, support plates 49 are fixed to the left and right sides of the rear end surface of the back plate 411. Both sets of support plates 49 are equipped with air nozzles 410. The air nozzles 410 are connected to the external air source through air pipes. Both sets of air nozzles 410 are inclined inward and are staggered in position. The air nozzles 410 can blow high-pressure gas toward the pressure test bench 5, removing any remaining debris from the pressure test bench 5 through the high-pressure gas, further cleaning the pressure test bench 5 and improving the cleaning effect. The two sets of air nozzles 410 are staggered in position. This arrangement allows the gas ejected from the air nozzles 410 to form two air streams, which helps to more comprehensively cover the area of the pressure test bench 5 and improve cleaning efficiency.
[0037] In this embodiment, a notch 47 is provided on the rear side of the enclosure cover 41, and the specifications of the notch 47 are adapted to those of the back plate 411. The notch 47 can meet the movement requirements of the support plate 49 and its upper air nozzle 410, thereby preventing obstruction to the support plate 49 and its upper air nozzle 410.
[0038] In this embodiment, the bottom of the enclosure cover 41 is configured as an inclined structure with a higher front and a lower back. The inclined bottom structure allows debris generated during the test to naturally slide along the slope to the rear of the enclosure cover 41 or the bottom outlet, and can more effectively guide the flow direction of the debris, thereby facilitating subsequent cleaning and collection.
[0039] The working principle of this concrete pressure testing machine with a debris cleaning function is as follows: in actual use, first place the concrete specimen on the pressure test bench 5, start the drive motor 431 of the lifting assembly 43, and raise the enclosure cover 41 to cover the upper end of the pressure test bench 5 to prevent debris from splashing during the test. During this process, when the drive motor 431 is started, its output shaft drives the first threaded screw 434 on the right side to rotate. Since the two groups of first threaded screws 434 are connected by the first belt 432 and the first pulley 433, the first threaded screw 434 on the left side will also rotate synchronously. As the first threaded screw 434 rotates, the first ear plates 437 at the front sides of the left and right ends of the enclosure cover 41 move up and down along the screw under the action of the thread. Since the two groups of screws rotate synchronously and in the same direction, the enclosure cover 41 is driven to move upward. Pressure is applied to the concrete specimen through the screw 1 and the upper pressure plate 7 inside the upper crossbeam 2 for testing. During the test, the enclosure cover 41 effectively prevents debris from splashing;
[0040] After the test is completed, the motor 454 of the translation assembly 45 is activated, driving the back plate 411 and the push plate 46 thereon to move horizontally along the upper end surface of the pressure test bench 5, pushing the scattered debris forward. Simultaneously, high-pressure gas is supplied to the gas nozzle 410 from an external air source, and the gas nozzle 410 ejects gas to remove the remaining debris on the pressure test bench 5. The push plate 46 and the gas nozzle 410 work together to push the debris toward the slag discharge conduit 42, where it is guided to the slag collection box 44 below for collection. The drive motor 431 of the lifting assembly 43 is then activated again, causing the enclosure 41 to descend, exposing the pressure test bench 5 to facilitate subsequent testing operations.
[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
