[0002] Concrete with different properties can be obtained through different proportions. In the design stage of a building, concrete with a specific proportion is required to meet different structural or functional requirements. At this time, in order to detect the actual effect of the concrete, small concrete test blocks are usually made to test the strength.

[0003] Common strength tests all use the impact method. Under the action of free fall, the impact head hits the concrete test block, but after the impact, the impact head will bounce up and then fall again, forming a secondary fall.

[0028] In one case of the present embodiment, the deflection driving assembly 29 includes a slide groove 38 arranged in the middle of the support platform 1, and the slide groove 38 is arranged on the right side of the rotating seat 25. The middle part of the slide groove 38 is slidably connected with a sliding seat 36. The upper surface of the sliding seat 36 is rotatably connected to the lower end of the support plate 37 on the right side, and the upper end of the support plate 37 is rotatably connected to the lower surface of the deflection guide plate 26. In order to better push the deflection guide plate 26 to rotate through the support plate 37, the sliding seat 36 is raised in the middle. When the support plate 37 rotates to a vertical state, the deflection guide plate 26 is in a horizontal state, and the left side of the support plate 37 will be close to the right side of the middle protrusion. A support block 24 fixedly connected to the left side of the rotating seat 25 is arranged on the left side of the rotating seat 25. When the deflection guide plate 26 is horizontal, the deflection guide plate 26 The lower surface of the left side fits the upper surface of the support block 24, and a threaded sleeve 31 set in a left-right direction is rotatably connected in the middle of the rotating seat 25. The middle part of the threaded sleeve 31 is threadedly connected to the jacking screw 30 set in the left-right direction. The right end of the jacking screw 30 is rotatably connected to the left side of the sliding seat 36, and a bearing seat 34 is provided on the front side of the support platform 1. The middle part of the bearing seat 34 is rotatably connected to a rotating rod 35 set in a front-back direction.

Therefore, the rotating rod 35 can rotate the threaded sleeve 31 by gear transmission, and the cooperation of the threaded sleeve 31 and the jacking screw 30 can make the sliding seat 36 move left and right.

[0029] In one case of the present embodiment, a material guide groove 27 is provided on the upper surface of the deflection guide plate 26, and an impact block 44 can be placed inside the material discharge box 8. When the impact block 44 moves to the left, it will fall into the material guide groove 27. The impact block 44 can move to the left along the material guide groove 27, and the test block 45 is placed on the support plate 40. A rotating rod 41 arranged in a left-right direction is provided on the front and rear sides of the right side of the back plate 39. The middle part of the rotating rod 41 is rotatably connected to a limit plate 43 arranged in an up-and-down direction. The upper part of the limit plate 43 away from the center of the back plate 39 is provided on the counterweight rod 42. When there is no test block 45 placed on the support plate 40, the lower ends of the limit plates 43 move closer to each other under the action of the counterweight rod 42.

[0030] During the implementation of this embodiment, the rotating rod 35 is first rotated, and the rotating rod 35 drives the sliding seat 36 to move to the left. At this time, the deflection guide plate 26 rotates clockwise, and the right end of the deflection guide plate 26 falls on the support platform 1, pushing the top plate 13 upward. According to the test requirements, an impact block 44 of a suitable size is selected and placed in the discharge box 8, and the block to be tested 45 falls from top to bottom on the limit plate 43. During the falling process of the block to be tested 45, the two limit plates 43 are pushed to separate. When the block to be tested 45 falls on the support plate 40, the front and rear limit plates 43 rotate to a vertical state. At this time, the entire equipment completes the sample clamping process.

[0031] Start the drive motor 16, and the drive motor 16 makes the second spindle 20 rotate clockwise through gear transmission. The second spindle 20 makes the first spindle 6 rotate clockwise through the cooperation of the U-shaped drive frame 21 and the U-shaped driven frame 22. At this time, the discharge box 8 will drive the impact block 44 to rotate clockwise along the center of the first spindle 6. According to the required impulse size, adjust the output angular velocity of the drive motor 16. When the angular velocity of the impact block 44 meets the requirement, quickly rotate the rotating rod 35, and the support plate 37 pushes the deflection guide plate 26 to rotate to a horizontal state. Since the deflection guide plate 26 only needs to deflect a small angle, it will not interfere with the rotating discharge box 8, so the deflection guide plate 26 can be quickly rotated to a horizontal state, and a contact sensor is provided on the support block 24. At this time, the driving motor 16 stops rotating, the U-shaped driving frame 21 and the U-shaped driven frame 22 are disengaged, and the discharge box 8 will contact the deflection guide plate 26 after rotating to the bottom, and the trapezoidal top block 28 will push the ball head 11 to move upward, the baffle 14 moves upward, and the impact block 44 moves to the left side under the action of inertia and disengages from the discharge box 8. The impact block 44 will move to the left side along the guide groove 27, and the impact block 44 will collide with the block to be tested 45. After the collision is completed, the impact block 44 will move to the right and disengage from the block to be tested 45. At this time, the strength performance can be judged according to the damage of the block to be tested 45.

[0032] The present invention is applicable to a test block strength testing device for architectural design. The rotating discharge box 8 drives the impact block 44 to rotate so that the impact block 44 has an initial momentum, and after the impact block 44 is separated from the discharge box 8, it will be in a horizontal state to complete the impact processing of the block to be tested 45. After the impact is completed, there will be no secondary collision, so that the error of the final test result is smaller.

[0033] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
