[0024] Next, in combination with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0025] Please refer to Figures 1 to 4 As shown, a pressure detection, protection and cleaning device for concrete test blocks includes a workbench 1, a frame body 3, a pressure measuring mechanism 2, a protective cover 6 and a cleaning assembly 5. Among them, the workbench 1 is used to place concrete test blocks. In this embodiment, a storage box 4 is fixedly provided at the bottom of the workbench 1 for collecting the fragments (hereinafter simply referred to as fragments) generated by the damaged concrete test blocks, facilitating the staff to uniformly collect and process the fragments. Among them, through grooves 11 communicating with the storage box 4 are respectively opened on the opposite sides of the top of the workbench 1, so that the fragments can fall into the interior of the storage box 4 through the through grooves 11.
[0026] The frame body 3 is fixedly provided on the top surface of the workbench 1 for supporting the pressure measuring mechanism 2. In this embodiment, the frame body 3 includes two relatively arranged side plates 31, a top plate 32 fixedly provided at the tops of the two side plates 31, and a rear plate 33 fixedly provided on one side of the two side plates 31 and the top plate 32. The cleaning assembly 5 is arranged at the bottom of the frame body 3 and above the workbench 1 for sweeping the fragments into the through grooves 11.
[0027] In this embodiment, the cleaning assembly 5 includes a screw rod 51 rotatably connected between two side plates 31, a slider 52 screwed onto the screw rod 51, a cleaning brush 53 fixed on the slider 52, and a power unit 54 for driving the screw rod 51 to rotate. The power unit 54 is a driving motor in the prior art and is used to drive the screw rod 51 to rotate forward or backward, which will not be elaborated here. The screw rod 51 is located above the workbench 1 and on the side close to the rear plate 33. The two through grooves 11 are respectively located at the axial two ends of the screw rod 51. A sliding groove 331 is formed on the rear plate 33, and the length direction of the sliding groove 331 is parallel to the axial direction of the screw rod 51. One side of the slider 52 is slidably connected to the sliding groove 331 to prevent the slider 52 from rotating along with the screw rod 51 during the rotation of the screw rod 51. Thus, by setting the sliding groove 331, during the rotation of the screw rod 51, the slider 52 can move along the axial direction of the screw rod 51, and further drive the cleaning brush 53 arranged on one side of the slider 52 to clean the top surface of the workbench. It should be noted that after the concrete test block experiment is completed, the staff will remove the large concrete test blocks, that is, the cleaning brush 53 cleans the small fragments.
[0028] Please refer to Figure 4 As shown, in this embodiment, one end of the cleaning brush 53 is fixedly connected to the slider 52, and the free end of the cleaning brush 53 extends towards the side away from the rear plate 33. A track 12 is formed on the top surface of the workbench 1 on the side away from the rear plate 33. A roller 531 is fixedly arranged at the free end of the cleaning brush 53, and the roller 531 abuts against the bottom surface of the track 12. By setting the roller 531 and the track 12, the movement of the cleaning brush 53 can be made more stable.
[0029] Please refer to Figure 3 As shown, the pressure measuring mechanism 2 is arranged on the frame 3 and above the workbench 1 for detecting the compressive strength of the concrete test block. In this embodiment, the pressure measuring mechanism 2 includes a hydraulic telescopic cylinder 21, a connecting rod 22, a pressure sensor 23, and a pressing plate 24 fixedly connected in sequence from top to bottom. The hydraulic telescopic cylinder 21 is vertically fixed at the top end of the frame 3, and the output end of the hydraulic telescopic cylinder 21 passes through the top wall of the frame 3 and is fixedly connected to the top end of the connecting rod 22. During implementation, the staff places the concrete test block on the top surface of the workbench 1, and then starts the hydraulic telescopic cylinder 21. The hydraulic telescopic cylinder 21 drives the connecting rod 22, the pressure sensor 23, and the pressing plate 24 to move towards the workbench 1, so that the pressing plate 24 presses the concrete test block. During the process of pressing the concrete test block, the pressure sensor 23 is used to sense the pressure.
[0030] The protective cover 6 is slidably connected to the lower part of the pressure measuring mechanism 2. Specifically, the protective cover 6 is slidably sleeved on the outer peripheral surface of the connecting rod 22, and the bottom end of the protective cover 6 is lower than the bottom surface of the pressure plate 24, which is used to prevent the fragments from splashing outwards during the extrusion and crushing of the concrete test block and causing harm to the surrounding staff. It should be noted that the distance between the bottom end of the protective cover 6 and the bottom surface of the pressure plate 24 is greater than or equal to the height of the concrete test block, so that the protective cover 6 completely covers the concrete test block during the pressure detection. Preferably, the material of the protective cover 6 is transparent plexiglass or expanded metal, which is convenient for the staff to observe during the test.
[0031] During implementation, the hydraulic telescopic cylinder 21 drives the connecting rod 22, the pressure sensor 23 and the pressure plate 24 to move towards the workbench 1. At this time, the protective cover 6 also moves downward. Since the bottom end of the protective cover 6 is lower than the bottom surface of the pressure plate 24, the concrete test block will be covered. When the concrete test block is extruded and crushed, the fragments will be restricted within the protective cover 6, so it will not cause harm to the surrounding staff. It should be noted that since the protective cover 6 and the connecting rod 22 are slidably connected, that is, the protective cover 6 can slide up and down along the axial direction of the connecting rod 22. Therefore, during the test, after the bottom end of the protective cover 6 abuts against the workbench 1, the protective cover 6 stops moving, and when the pressure plate 24 continues to move downward, relative movement occurs between the top end of the protective cover 6 and the connecting rod 22. When the experiment is completed, the output end of the hydraulic telescopic cylinder 21 resets and contracts, and at this time, the protective cover 6 resets by its own gravity.
[0032] Preferably, fixed rings 221 are respectively fixedly sleeved on the top and bottom ends of the connecting rod 22, the top end of the protective cover 6 is slidably connected between the two fixed rings 221, and a spring 222 for pushing the protective cover 6 to move towards the workbench 1 is also sleeved on the outside of the connecting rod 22. This is convenient for the protective cover 6 to reset quickly. At the same time, by setting the fixed ring 221 at the bottom end of the connecting rod 22, the protective cover 6 no longer contacts the pressure sensor 23, avoiding the influence of the protective cover 6 on the detected value of the pressure sensor 23.
[0033] When the utility model is specifically implemented, the staff places the concrete test block to be detected on the top surface of the workbench 1, and then starts the hydraulic telescopic cylinder 21. The hydraulic telescopic cylinder 21 drives the connecting rod 22, the pressure sensor 23, the pressing plate 24 and the protective cover 6 to move towards the workbench 1. At this time, the protective cover 6 also moves downward to cover the outside of the concrete test block. When the concrete test block is squeezed and broken, the fragments will be restricted within the protective cover 6, so that it will not cause harm to the surrounding staff. After the detection is completed, the pressure measuring mechanism 2 resets. At this time, the staff removes the large concrete test block, and then starts the power part 54 of the cleaning assembly 5. The power part 54 drives the screw rod 51 to rotate forward or backward. At this time, the slider 52 screwed to the screw rod 51 moves along the axial direction of the screw rod 51, thereby driving the cleaning brush 53 to clean the workbench 1. Since the two through grooves 11 are respectively located at the two axial ends of the screw rod 51, the cleaning brush 53 will sweep the fragments into the through grooves 11 to facilitate the staff to uniformly collect and process the fragments.
[0034] The above description is only the preferred embodiment of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
