Description

Technical Field

[0001] The invention relates to the technical field of precast concrete part detection, and in particular to a precast concrete part strength detection device. Background Art

[0002] Strength testing of precast concrete parts is an important part of ensuring the quality and safety of construction projects. At present, strength testing devices generally achieve strength testing by applying pressure to precast parts. This method is mainly based on the principle of load-bearing test, that is, using a testing machine to load concrete samples and measure their strain and stress under different loads, so as to calculate the compressive strength of concrete. The load-bearing test can directly reflect the ultimate capacity of concrete under stress, and is an intuitive and effective method to evaluate the strength of concrete.

[0003] However, in the prior art, when conducting strength testing of precast concrete parts, since it is necessary to apply a large pressure to the precast parts to measure their compressive strength, this often causes concrete damage in the testing area, and then fragments are scattered. The generation of these fragments not only increases the cleaning work after the test, which often requires manual or tool cleaning before continuing the next round of testing operations, but also seriously affects the continuity of batch testing. The cleaning work is not only time-consuming and labor-intensive, increasing the testing cost, but also interrupts the testing process, making the entire testing process incoherent, thereby affecting the testing efficiency. In the case where the strength of a large number of precast concrete parts needs to be quickly and accurately evaluated, the efficiency reduction caused by the cleaning work after the test is particularly obvious.

[0004] Therefore, it is necessary to propose a concrete precast part strength detection device to solve the above problems. Summary of the invention

[0049] In addition, if Figure 3-Figure 6 , Figure 11-Figure 17As shown, in order to ensure the stability of the upper rotating ring 5 for detection, a locking mechanism for locking the end face gear ring 19 is provided at the bottom of the rotating ring 5, and the locking mechanism includes a fixing plate 17 fixed to one side of the inner cavity of the support tube 10, and a locking plate 16 is slidably connected to the side of the fixing plate 17 close to the lifting frame 6, and chamfers are provided at both ends of the locking plate 16, and a convex plate 42 is provided on one side of the fixing plate 17, and a second elastic member 43 is provided between the locking plate 16 and the convex plate 42, and the second elastic member 43 is preferably a spring, and the fixing plate 1 A locking frame 21 is vertically slidably connected to the side away from the locking plate 16, one end of the locking frame 21 extends to the outside of the support tube 10, and a locking tooth 40 adapted to the end face gear ring 19 is arranged on the top of the end extending to the outside of the support tube 10, and a second through groove 41 corresponding to the locking frame 21 is arranged on the side wall of the support tube 10, and the end of the locking frame 21 away from the fixing plate 17 passes through the second through groove 41 and extends to the outside of the support tube 10, and the inner cavity height of the second through groove 41 is greater than the thickness of the end of the locking frame 21, so as to adapt to the lock. The stop frame 21 moves up and down, and a first guide groove 47 is provided on the side wall of the locking frame 21 near the fixed plate 17, and a second long groove 46 corresponding to the first guide groove 47 is provided on the side wall of the fixed plate 17. A third drive shaft 45 corresponding to the second long groove 46 is provided on the side of the locking plate 16 near the fixed plate 17, and an end of the third drive shaft 45 away from the locking plate 16 passes through the second long groove 46 and extends to the inner side of the first guide groove 47. The third drive shaft 45 and the first guide groove 47 are configured so that when the locking plate 16 compresses the second When the elastic member 43 is engaged, the locking frame 21 is displaced downward, thereby separating the locking tooth 40 from the end face gear ring 19, and a guide slope 44 is provided at the upper end of the locking plate 16, and a blind hole is provided on the side wall of the locking plate 16, and a fourth drive shaft 49 corresponding to the locking plate 16 is movably connected to the inner side of the blind hole, and a third elastic member 50 is provided between the fourth drive shaft 49 and the inner wall of the blind hole, and the third elastic member 50 is preferably a spring, and the fourth drive shaft 49 is used to push the locking plate 16 to compress the second elastic member 43 through the guidance of the chamfers at both ends of the locking plate 16.

[0050] When in use, when the second roller 15 is displaced to the second driving plate 37, it will be displaced to the inner side of the second driving plate 37 under the guidance of the chamfer at the end of the second driving plate 37, so that the second roller 15 pushes the moving rod 27, the first elastic member 33 is compressed, and the square tube 28 and the moving rod 27 are driven by the moving rod 27 as a whole. Under the action of the guide block 35 and the spiral groove 34, the hollow shaft 31 drives the protective cover plate 9 to flip, and flip from horizontal to vertical, and the top of the first through groove 12 is opened. At this time, the prefabricated part to be inspected can be placed in the first through groove 12 and supported by the two end support plates 23 at the lower end of the first through groove 12. It should be noted that the rotation of the swivel 5 is driven by the lifting of the lifting frame 6. Specifically, when the driving source 3 drives the lifting frame 6 to rise, the rack 48 follows the rotation, and the inspection The rack 48 will mesh with the second gear 39 only after the probe 8 is removed from the first through slot 12 where it is located. Then, due to the action of the one-way bearing, the second gear 39 drives the rotating shaft 38 to rotate. The rotating shaft 38 drives the rotating ring 5 to rotate through the meshing relationship between the first gear 20 and the end face gear ring 19. When the rack 48 rises to the limit distance, the rotation amplitude of the rotating ring 5 is the distance between the two first through slots 12, so that one of the first through slots 12 will come under the detection head 8, and before the first through slot 12 comes under the detection head 8, the corresponding second roller 15 will separate from the second driving plate 37, so that the first elastic member 33 is reset, the moving rod 27, the square tube 28, and the second driving shaft 29 are reset as a whole, and the protective cover plate 9 is flipped to the water under the action of the guide block 35 and the spiral groove 34. The first gear 39 is engaged with the rack 48, and the second gear 39 drives the rotating shaft 38 to rotate relative to the rotating shaft 38, and the rotating shaft 38 does not rotate. At this time, the rotating ring 5 remains stationary. Then, the detection head 8 enters the first through groove 12 through the notch 30 to apply uniform pressure to the preform to perform strength detection. A pressure sensor can be set at the upper end of the detection head 8 to achieve accurate detection. After the detection is completed, the lifting frame 6 is driven to rise and reset again. Similarly, the second gear 39 will mesh with the rack 48 only after the detection head 8 is removed from the first through groove 12. At this time, the second gear 39 drives the rotating shaft 38 to rotate, and then the first gear 20 drives the rotating ring 5 to rotate through the end face gear ring 19. The first roller 14 corresponding to the preform after the rotation detection of the swivel 5 will be displaced to the inner side of the first driving plate 36 under the guidance of the chamfer of the end of the first driving plate 36, so that the moving frame 13 is pushed and displaced by the first roller 14. When the moving frame 13 is displaced, the first driving shaft 25 will be driven to displace. Under the action of the second guide groove 51, the support plate 23 is displaced to the inner side of the accommodating groove 11, and then the two support plates 23 corresponding to the first through groove 12 are separated. The preform and the broken pieces after the detection will be pushed down by the side wall of the lower end of the first through groove 12, and then slide down from the slope at the top of the base 4. Moreover, due to the movable sleeve connection between the square tube 28 and the moving rod 27, it can adapt to the displacement of the support plate 23. Afterwards, as the swivel 5 rotates, the vertical shaft 22 at the bottom of the moving frame 13 will gradually move outward and reset under the guidance of the reset plate 18.Then the moving frame 13 moves outward and resets, the support plate 23 resets and merges, and then with the rotation of the swivel 5, the second roller 15 comes to the second drive plate 37 again, and then the protective cover plate 9 is opened to continue loading. In this cycle, the reciprocating lifting of the lifting frame 6 can realize one rotation of the swivel 5, automatically realize the change of the work station, and automatically realize protection and unloading with the rotation. At the same time, the first through slot 12 corresponding to the second drive plate 37 can be loaded during detection, which increases production continuity and improves efficiency;

[0051] It should be noted that after the detection, when the lifting frame 6 moves upward, it will drive the fourth drive shaft 49 to move upward. Before the rack 48 meshes with the second gear 39, the fourth drive shaft 49 will push the locking plate 16 to squeeze the second elastic member 43 under the guidance of the chamfer at the lower end of the locking plate 16, so that the locking plate 16 drives the third drive shaft 45 to move. Under the action of the first guide groove 47, the locking frame 21 moves downward, the locking tooth 40 is separated from the end face gear ring 19, and the lock is released. Then, when the rack 48 meshes with the second gear 39, the rotation of the swivel 5 can be realized. When the lifting frame 6 rises to the limit distance, Under the action of the chamfer at the upper end of the locking plate 16, the second elastic member 43 drives the locking plate 16 to reset, and then the locking tooth 40 locks the end face gear ring 19 again. At this time, the fourth drive shaft 49 corresponds to the guide slope 44. During the subsequent downward movement detection, the fourth drive shaft 49 will compress the third elastic member 50 under the guidance of the guide slope 44. During this period, the locking plate 16 remains stationary and the swivel 5 is locked. After the detection is completed, the lifting frame 6 drives the fourth drive shaft 49 to rise, which can ensure the stability of the swivel 5 during the downward movement detection, and can unlock and drive the swivel 5 to rotate during the upward reset period, and this cycle is repeated.
