Description

[0002] At present, before concrete test blocks are used, geometric deviation tests need to be performed on the test blocks. The existing test method uses manual measurement with a vernier caliper. During the measurement, each edge needs to be measured at least 3 times, and then the average value is calculated. This method is time-consuming and labor-intensive. The angle needs to be measured with a universal angle ruler, and the pressure-bearing surface needs to be measured with a feeler gauge, which makes the manual workload relatively large. In addition, the results of each measurement need to be recorded, the original records need to be saved, and then a test report needs to be issued. In addition to increasing the workload, the work efficiency is greatly reduced.

[0037] The horizontal column 50 is embedded in the strip groove 27. In the original state, the horizontal column 50 is just embedded in the strip groove 27 to block the strip groove 27. The horizontal column 50 is located below the guide rod 15, and the support column 51 is located on both sides of the guide rod 15.

[0038] A micro vibrator may be provided at one side end of the bottom of the support base plate 8, the inner diameter of the through hole 26 in the middle of the support base plate 8 is larger than the outer diameter of the bottom column 9, the outer diameter of the guide rod 15 is smaller than the inner diameter of the limit plate 18, and a rubber ring is provided at the contact end of the guide rod 24 and the support plate 16, so that after the support base plate 8 vibrates, the vibration force will not be directly applied to the test block 6. When the support base plate 8 generates vibration force, the dust and impurities that fall on it will be pushed to one side by the vibration force, and fall from the flow groove on one side of the baffle 28 into the receiving trough 29 on the lower side.

[0039] Detailed usage and function of this embodiment:

[0040] The test block 6 is placed in the positioning groove 5, and the bottom of the test block 6 contacts with the magnetic plate 11, pressing the magnetic plate 11 downward. After the magnetic plate 11 is subjected to pressure, it presses the pyramid branch end 10 below downward, and the pyramid branch end 10 will press the bottom column 9 through the through hole 26, and the side of the pyramid branch end 10 will press the side limiting ball 13 to be squeezed outward, and the limiting ball 13 pushes the guide rod 15 outward, prompting the guide rod 15 to push the limiting displacement plate 21 connected to the outer end to spread outward. At this time, a spacing will be formed between the limiting displacement plate 21 and the test block 6, so that the particles and powder dropped from the concrete test piece can fall from the spacing downward into the receiving drawer 7 below.

[0041] When the displacement limit plate 21 is pushed outward, the bottom tooth column 22 on one side of the outer side will drive the meshing gear 1 38 below to rotate. After the gear 1 38 rotates, it will drive the secondary pulley 37 connected on the side. The secondary pulley 37 drives the main pulley 34 to rotate through the belt 39. The main pulley 34 will drive the threaded rod 33 connected on the side to rotate. After the threaded rod 33 rotates, it will drive the meshing gear 2 40 below to rotate. The gear 2 40 drives the meshing lower filter plate 41 below to move left and right. The lower filter plate 41 drives the L-shaped plate 42 at one end of the top. The L-shaped plate 42 drives the side tooth plate 43 of the side groove to move left and right. When the side tooth plate 43 moves left and right, it will drive the meshing gears 45 and gear 3 44 on both sides above. After the gear 45 rotates, It will drive the internal fan blades 57 to rotate, and the wind force generated by the fan blades 57 will have a certain heat dissipation effect on the inside. After the gear three 44 rotates, it will drive the cam 47 set at the inner end of the shaft rod 46 to rotate. After the cam 47 rotates, the side edge will push the upper lifting column 48 to move up and down continuously. When the lifting column 48 goes up, it pushes the horizontal column 50 through the strip groove 27 upward, and the support columns 51 on both sides of the top will push up against the bottom of the test block 6, and the bottom of the test block 6 will increase the support contact points. When the lifting column 48 goes down, the bottom contact surface of the test block 6 will become less, and the bottom of the test block 6 will contact with the magnetic plate 11. The bottom is equivalent to a tumbler-shaped structure. At this time, the angle of the test block 6 can be conveniently adjusted, so that it is convenient to detect it after the angle is adjusted.

[0042] At the same time, the cylinder 53 and the gas rod 52 can be driven to produce telescopic movement, the gas rod 52 drives the L-shaped plate 42 to move left and right, the L-shaped plate 42 drives the side tooth plate 43 and the lower filter plate 41 to move left and right, when the lower filter plate 41 moves left and right, it will drive the meshing gear 2 40 above to rotate, the gear 2 40 drives the threaded rod 33, the threaded rod 33 will finally drive the bottom tooth column 22 to move through two connected pulleys, when the bottom tooth column 22 moves toward the middle at the same time, the limit displacement plate 21 connected at the inner end will move toward the middle at the same time, the bottom side plate 23 moves to the top side of the supporting bottom plate 8, the honeycomb abutment plate 25 on the upper inner side of the limit displacement plate 21 will abut against the test block 6 in the middle, and the test block 6 will be positioned and clamped.

[0043] When the lower filter plate 41 moves left and right, the brush 62 at the bottom will clean the bottom of the receiving trough 29 to prevent the dust or powder from accumulating and causing blockage, thus achieving a certain discharge effect. In addition, when the agglomerated powder or impurities fall onto the lower filter plate 41, the powder falling from the lower filter plate 41 will hit the adjacent side walls of the trapezoidal crushing plate 60 when the lower filter plate 41 moves left and right. After the powder is hit, it will be crushed, which is convenient for discharge. The bottom wall of the receiving trough 29 is set to be a slope inclined toward the drop opening 54, which is convenient for material discharge. The material discharged just enters the receiving drawer 7 below. The collected dust and dirt can be processed by pulling out the receiving drawer 7.

[0044] Through the above specific implementations, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
