[0033] See also Figures 1 to 6 In an embodiment of the utility model, a cementitious material strength testing device includes a pressure testing machine 1 composed of a base 101, a column 102, a pressure platform 103, a top seat 104, a hydraulic cylinder 105, and a pressure platform 106.

[0034] The cleaning component 3 includes a cleaning unit and a linkage unit;

[0035] The cleaning unit is used to clean the broken pieces on the surface of the pressure platform 103;

[0036] The linkage unit transmits the moving power on the pressure table 106 to the cleaning unit, driving the cleaning unit to reciprocate;

[0039] The bottom level of the cleaning plate 302 is flush with the top level of the pressure platform 103. The reciprocating rotation of the rotating column 301 drives the cleaning plate 302 to scrape the top of the pressure platform 103, thereby cleaning the broken pieces on the top of the pressure platform 103.

[0040] The linkage unit includes a guide groove 303, a lifting ring 304, a connecting rod 305, and a telescopic guide column 306;

[0041] The guide groove 303 is provided on the outer side of the rotating column 301, the lifting ring 304 is sleeved on the outer side of the rotating column 301, the telescopic guide column 306 is horizontally slidably connected to the inner side of the lifting ring 304 and is slidably connected to the guide groove 303. When the lifting ring 304 moves up and down, the telescopic guide column 306 is driven to move along the track of the guide groove 303, and the rotation of the rotating column 301 is powered by the extrusion between the telescopic guide column 306 and the inner wall of the guide groove 303.

[0042] The connecting rod 305 is fixedly connected between the top of the pressure platform 106 and the lifting ring 304, and is used to achieve synchronous up and down movement of the pressure platform 106 and the lifting ring 304;

[0043] The guide groove 303 is composed of a first vertical groove 3031, a second vertical groove 3032, a first spiral groove 3033, and a second spiral groove 3034;

[0044] The second vertical groove 3032 is connected to the bottom of the first vertical groove 3031, the bottom of the first spiral groove 3033 is connected to the top of the second vertical groove 3032, the bottom of the second spiral groove 3034 is connected to the top of the first spiral groove 3033, and the top of the second spiral groove 3034 is connected to the top of the first vertical groove 3031;

[0045] The depth of the second vertical groove 3032 is greater than the depth of the first vertical groove 3031 , and the bottom depth of the first spiral groove 3033 is the same as the depth of the second vertical groove 3032 ;

[0046] The depths of the first spiral groove 3033 and the second spiral groove 3034 gradually decrease from bottom to top, and the top depth of the second spiral groove 3034 is less than the depth of the first vertical groove 3031;

[0047] The linkage unit also includes a spring 307. A telescopic slot for the telescopic guide column 306 to telescope horizontally is provided inside the lifting ring 304. The spring 307 is fixed between the telescopic guide column 306 and the inner wall of the telescopic slot. The lifting ring 304 is used to adapt to the notch depth of different parts of the guide slot 303 through telescopic movement.

[0048] A collecting trough 4 is formed on the top of the base 101 and located outside the pressure platform 103. The collecting trough 4 is used to collect the broken pieces for later centralized cleaning.

[0049] In this embodiment: when the compressive strength of the cementitious material is tested, the cementitious material specimen is placed on the pressure platform 103, and then the hydraulic cylinder 105 is started, and the hydraulic cylinder 105 moves downward to drive the pressure platform 106 to move downward, and the pressure platform 106 contacts the top of the cementitious material specimen and squeezes it. The pressure that the cementitious material specimen bears when it is squeezed and broken is the maximum pressure resistance of the cementitious material specimen;

[0050] During the downward movement of the pressure platform 106, the pressure platform 106 can drive the lifting ring 304 to move downward along the outer wall of the rotating column 301 through the connecting rod 305, and the telescopic guide column 306 moves along the first vertical groove 3031 to the inside of the second vertical groove 3032. At this time, the telescopic guide column 306 will further move into the second vertical groove 3032 under the elastic force of the spring 307. During the above process, since the first vertical groove 3031 and the second vertical groove 3032 are in a vertical straight line state as a whole, the rotating column 301 remains in a non-rotating state;

[0051] When the pressure test is completed, the hydraulic cylinder 105 runs in the reverse direction to drive the pressure platform 106 to move up and reset. At this time, the telescopic guide column 306 will first move up to the top of the second vertical groove 3032 along the trajectory of the second vertical groove 3032. At this time, since the depth of the telescopic guide column 306 protruding into the second vertical groove 3032 is greater than the depth of the first vertical groove 3031, the telescopic guide column 306 cannot enter the first vertical groove 3031 and can only move upward along the trajectory of the first spiral groove 3033. Since the lifting ring 304 itself cannot rotate, the rotating column 301 will rotate on its own, and the rotating column 301 will drive the cleaning plate 302 to rotate toward the pressure platform 103. The cleaning plate 302 will pass above the pressure platform 103 and scrape the upper surface of the pressure platform 103. In this way, the residual debris on the pressure platform 103 can be cleaned away and fall into the collecting tank 4.

[0052] When the telescopic guide column 306 moves from the first spiral groove 3033 to the inside of the second spiral groove 3034, the rotating column 301 will rotate in the reverse direction, so that the cleaning plate 302 can be reset, and finally the telescopic guide column 306 enters the top of the first vertical groove 3031;

[0053] The cooperation of the above multiple parts can realize the automatic cleaning operation of the broken pieces on the top of the pressure platform 103, so that continuous detection operation can be carried out, which effectively improves the batch detection efficiency.

[0054] Please refer to Figures 1 to 3 A protective plate 2 is provided between two adjacent columns 102 , and one protective plate 2 can be rotated and opened by a hinge, and the protective plate 2 that can be opened is away from the rotating column 301 .

[0055] In this embodiment: the protective plate 2 can shield the cementitious material fragments to prevent the fragments from splashing. One of the protective plates 2 is rotatably connected to a column 102 through a hinge and is detachably connected to another column 102 through a latch. This protective plate 2 can be rotated to open, so that the cementitious material specimen can be placed.

[0056] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
