[0025] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] Embodiment 1:

[0027] See Figures 1-3, A fixture for fixing a pressure tester, including a horizontally arranged fixing plate 1. A bearing seat 11 is arranged on the fixing plate 1. A vertically arranged rotating shaft 12 is arranged on the bearing seat 11. The lower end of the rotating shaft 12 is inserted into the inner ring hole of the bearing in the bearing seat 11 with an interference fit, so that the rotating shaft 12 is rotatably connected to the bearing seat 11. A horizontal rotating platform 13 is arranged at the upper end of the rotating shaft 12. The rotating platform 13 is a circular turntable. A driving mechanism 2 for driving the rotating shaft 12 to rotate is arranged on one side of the rotating shaft 12. Two clamping mechanisms 3 for fixing the concrete blocks on the rotating platform 13 are symmetrically arranged on both sides of the rotating platform 13. An annular material receiving groove 4 is arranged outside the rotating platform 13. A pushing plate 41 is arranged in the material receiving groove 4. The width of the pushing plate 41 is slightly smaller than that of the material receiving groove 4. A guiding rod 42 is fixed at the upper end of the pushing plate 41. The guiding rod 42 is connected to a rotating rod 43 arranged radially on the side wall of the rotating shaft 12. A discharge port 44 is arranged at the bottom of the material receiving groove 4. A blanking hole 14 is arranged on the fixing plate 1 corresponding to the discharge port 44. By driving the rotating shaft 12 to rotate through the driving mechanism 2, the rotating platform 13 is driven to rotate, and the concrete test block on the rotating platform 13 is rotated to a position convenient for the two clamping mechanisms 3 to clamp. The concrete test block is clamped by the two groups of clamping mechanisms 3, and the clamping stability is good, and the concrete test block will not shift laterally. When the concrete test block completes the pressure test, the rotating shaft 12 is driven to rotate through the driving mechanism 2 to drive the rotating platform 13 to rotate, and the waste residue on the rotating platform 13 is transferred to the annular material receiving groove 4 under the action of centrifugal force. The rotation of the rotating shaft 12 drives the pushing plate 41 to rotate in the annular material receiving groove 4 through the rotating rod 43 and the guiding rod 42, and the waste residue collected in the annular material receiving groove 4 is pushed into the discharge port 44 and discharged through the blanking hole 14, which is convenient for the detection work of the next concrete test block. The fixture is convenient for disassembly and installation.

[0028] In this embodiment, referring to Figure 1 , the driving mechanism 2 includes a servo motor 21, a driving gear 22, and a driven gear 23. The driven gear 23 is coaxially fixed on the outer wall of the rotating shaft 12. A driving gear 22 that can mesh with it is arranged on one side of the driven gear 23. A groove 15 is arranged on the bottom surface of the fixing plate 1. The groove 15 communicates with the front and rear end faces of the fixing plate 1 respectively. A vertically arranged servo motor 21 is arranged in the groove 15. The output shaft of the servo motor 21 extends upward through the fixing plate 1 to the upper part of the fixing plate 1 and is coaxially fixedly connected to the driving gear 22. The driving gear 22 is driven to rotate by the servo motor 21. The driving gear 22 and the driven gear 23 mesh and rotate with each other. The rotation of the driven gear 23 drives the rotating shaft 12 to rotate coaxially. The coaxial rotation of the rotating shaft 12 drives the rotating platform 13 to rotate coaxially. On the one hand, different faces of the concrete block can be rotated between the two clamping mechanisms 3, so that the concrete block can be stably clamped. On the other hand, during the rotation of the rotating platform 13, the concrete test waste residue on it can be transferred to the material receiving groove 4 under the action of centrifugal force, which is convenient for quickly cleaning the waste residue on the rotating platform 13, and the cleaning speed is fast.

[0029] In this embodiment, referring to Figure 2 , each clamping mechanism 3 includes a bracket 31, a clamping plate 32, guide rails 33, sliders 34, a moving plate 35, and a hydraulic cylinder 36. The bracket 31 is fixed on the fixed plate 1. Two guide rails 33 are arranged on the bracket 31. Two sliders 34 are symmetrically arranged on the two guide rails 33. A moving plate 35 is arranged on the two sliders 34. Both ends of the moving plate 35 are fixedly connected to the two sliders 34 respectively. A clamping plate 32 is arranged in the middle of the moving plate 35. A hydraulic cylinder 36 is arranged between the two guide rails 33. The hydraulic cylinder 36 is fixed on the bracket 31. The telescopic end of the hydraulic cylinder 36 is connected and fixed to the clamping plate 32. By driving the moving plate 35 to move through the hydraulic cylinder 36, the moving plate 35 is guided by the two sliders 34 on the two guide rails 33. The moving plate 35 can drive the clamping plate 32 to stably clamp the concrete test block, and the clamping stability is good.

[0030] In this embodiment, the bracket 31 includes a column 311, a cross beam 312, and a longitudinal beam 313. The column 311 is vertically fixed on the fixed plate 1. The upper end of the column 311 is fixed with a horizontally arranged cross beam 312. Two longitudinally arranged horizontal longitudinal beams 313 are fixed at both ends of the cross beam 312. The two guide rails 33 are parallelly installed on the two longitudinal beams 313. Through the bracket 31, the guide rails 33 and the sliders 34 can be stably supported, so as to smoothly send the clamping plate 32 to the outside of the concrete block and quickly clamp the concrete block.

[0031] In this embodiment, referring to Figure 2 , the clamping surface of each clamping plate 32 is an arc surface. A plurality of vertically distributed teeth 321 are arranged on the arc surface. By arranging the teeth 321 on the clamping surface, the stability of clamping the concrete is increased. For the curved concrete block, multiple parts of the concrete test block can be clamped by fitting the curved surface of the concrete test block, and the clamping stability is good.

[0032] In this embodiment, referring to Figure 1 , a receiving box 5 is arranged below the blanking hole 14. The waste residue generated by the pressure test is collected through the receiving box 5, which is convenient for cleaning, collecting and recycling.

[0033] In this embodiment, referring to Figures 1-3 , a flange 10 is arranged on the outer wall of the lower end of the fixed plate 1. A plurality of bolt holes 101 are arranged on the flange 10 along the circumferential direction. The flange 10 is fixedly connected to the workbench 61 of the pressure tester through bolts, so that the fixed plate 1 will not have relative displacement with the workbench 61 of the pressure tester, and it is ensured that the concrete block can be stably fixed by the fixing tooling.

[0034] In this embodiment, since a large axial force needs to be borne by the rotating shaft 12 during the pressure test of the concrete test block, the bearing in the bearing seat 11 needs to be set as a thrust ball bearing to bear a large axial force and radial force.

[0035] As can be seen from the above technical solution, during use, first, the fixing plate 1 is fixed in the middle of the workbench 61 of the pressure tester 6 through bolts. The model of the pressure tester 6 is selected as HCT306D. The concrete test block is placed in the middle of the fixing plate 1. The controller is used to control the servo motor 21 to drive the driving gear 22 to rotate. The driving gear 22 and the driven gear 23 mesh and rotate with each other. The rotation of the driven gear 23 drives the coaxial rotation of the rotating shaft 12. The coaxial rotation of the rotating shaft 12 drives the coaxial rotation of the rotating platform 13, so that the clamping surfaces on both sides of the concrete block are rotated between the two clamping mechanisms 3. Then, the controller is used to control the hydraulic cylinders 36 on both sides to drive the moving plate 35 to move towards the concrete test block. The moving plate 35 is guided by the two sliders 34 on the two guide rails 33. The moving plate 35 drives the clamping plate 32 to clamp the concrete test block. Then, the pressure tester applies pressure to the concrete test block. After the test is completed, the controller is used to control the hydraulic cylinders 36 on both sides to drive the moving plate 35 to move away from the concrete test block. Then, the controller is used to control the servo motor 21 to drive the driving gear 22 to rotate. The driving gear 22 and the driven gear 23 mesh and rotate with each other. The rotation of the driven gear 23 drives the coaxial rotation of the rotating shaft 12. The coaxial rotation of the rotating shaft 12 drives the coaxial rotation of the rotating platform 13, so that the crushed waste on the rotating platform 13 is cleaned into the annular material receiving groove 4 by centrifugal force. At the same time, the coaxial rotation of the rotating shaft 12 will also drive the pushing plate 41 to rotate in the annular material receiving groove 4 through the rotating rod 43 and the guiding rod 42, and push the waste collected in the annular material receiving groove 4 into the discharge port 44 and discharge it into the material receiving box 5 through the material discharging hole 14 for collection.
