Description

[0002] As an important building material, the strength index of precast concrete bricks is directly related to the quality and safety of buildings. Therefore, accurate detection of the strength of precast concrete bricks is crucial. The precast concrete brick strength detection device is an instrument specially used to evaluate the compressive strength properties of precast concrete bricks. By applying gradually increasing pressure to the precast brick sample and recording its mechanical parameters during the destruction process, its strength grade can be determined.

The support frame 21 is arranged on the rear side of the base plate 1, and the downward pressure cylinder 22 is arranged on the upper end of the support frame 21. It should be noted that in a preferred embodiment, a horizontally arranged horizontal slide 7 is arranged on the upper end of the support frame 21, and the downward pressure cylinder 22 is adjustably mounted on the horizontal slide 7 through a mounting plate, and the vertical slide 23 is fixedly arranged on the front side of the support frame 21. The slide 24 is slidably arranged on the vertical slide 23, and the slide 24 is connected to the piston rod of the downward pressure cylinder 22, and the pressure measuring head is fixedly arranged on the slide 24; wherein the pressure measuring head includes a pressure plate 25, a guide column 26, a vertical spring 27, an upper connecting plate 28, a lower connecting plate 29 and a detection gauge 30, one side of the pressure plate 25 is fixedly connected to the slide 24, and the guide column 26 is provided with Four, rectangular arrangement, the lower end of the guide column 26 is fixedly connected to the pressure plate 25, each guide column 26 is respectively sleeved with a vertical spring 27, the upper connecting plate 28 is fixedly connected to the piston rod of the downward pressure cylinder 22, the upper connecting plate 28 and the lower connecting plate 29 are stacked up and down, the upper connecting plate 28 and the lower connecting plate 29 are both rectangular plates, the lower connecting plate 29 is movably connected to the piston rod of the downward pressure cylinder 22, the detection gauge 30 is arranged on the upper side of the upper connecting plate 28, the upper connecting plate 28 is provided with a measuring hole 281 which runs through from top to bottom, the pressure sensor of the detection gauge 30 extends into the measuring hole 281 and contacts with the lower connecting plate 29, the upper connecting plate 28 and the lower connecting plate 29 are provided with four sliding holes 282 which are compatible with the guide column 26, the upper end of the vertical spring 27 is fixedly connected to the lower connecting plate 29, and the lower end of the vertical spring 27 is fixedly connected to the pressure plate 25.

[0027] The piston rod of the downward pressure cylinder 22 drives the upper connecting plate 28 and the lower connecting plate 29 to move synchronously, and drives the pressing plate 25 to move through the guide column 26 and the vertical spring 27. When the pressing plate 25 abuts against the concrete brick placed on the detection platform 3, the pressing plate 25 applies an upward force to the lower connecting plate 29 through the vertical spring 27, and causes the lower connecting plate 29 and the upper connecting plate 28 to produce a relative displacement. The pressure sensor measures the pressure and records and displays it through the detection meter 30. Optionally, the detection meter 30 can use a high-precision stainless steel earthquake-resistant intelligent digital display digital pressure gauge, product model: MD-S210-0.1 grade.

[0028] Specific reference Figure 4The inspection platform 3 includes a discharge plate 31, a left support 32, a right support 33 and a vertical top roller 34. The left support 32 and the right support 33 are respectively arranged at the two ends of the upper side of the bottom plate 1. A rotating shaft is arranged at the upper end of the left support 32. One end of the discharge plate 31 is connected to the rotating shaft. The right support 33 is in an inverted L shape. A telescopic block 4 is arranged on the upper end of the right support 33 for horizontal sliding. The end of the discharge plate 31 away from the rotating shaft is overlapped on the upper side of the telescopic block 4. When the discharge plate 31 is overlapped on the upper side of the telescopic block 4, the two ends of the discharge plate 31 are at the same height and are in a horizontal state. The telescopic block 4 is squeezed inward to separate the discharge plate 31 from the telescopic block 4. At this time, the discharge plate 31 can rotate along the rotating shaft due to its own weight. At this time, the discharge plate 31 is in an inclined state. The vertical top roller 34 is arranged on the lower side of the discharge plate 31, and the vertical top roller 34 is perpendicular to the discharge plate 31. For specific reference Figure 5 The telescopic block 4 includes an inclined slider 41, a transverse top roller 42 and a transverse spring 43. The inclined slider 41 is slidably connected to the right support 33. The transverse top roller 42 is fixedly arranged on the lower side of the inclined slider 41. The transverse spring 43 is sleeved on the transverse top roller 42. A force pointing in the direction of the right support 33 is applied to the transverse top roller 42, so that the inclined slider 41 can slide relative to the right support 33. At this time, the discharge plate 31 is out of contact with the inclined slider 41, and the transverse spring 43 is squeezed and stored.

[0029] Specific reference Figure 6 , wherein the collecting bin 5 comprises a bin body 51, a release rod 52, a trapezoidal block 53 and a driving cylinder 54, the bin body 51 is arranged directly below the discharge plate 31, a double-track slide is arranged on the bottom plate 1, a slider adapted to the slide is arranged at the bottom of the bin body 51, the trapezoidal block 53 is arranged on the side of the bin body 51 close to the left support 32, the long side of the trapezoidal block 53 faces downward, the short side faces upward, and the inclined surface is away from the bin body 51, it should be particularly noted that the vertical top roller 34 is located on the movement path of the trapezoidal block 53, the driving cylinder 54 is arranged on the bottom plate 1, and is used to drive the bin body 51 to slide horizontally along the bottom plate 1, and a bin door 511 is arranged on the side of the bin body 51 away from the trapezoidal block 53. In this embodiment, the piston rod of the driving cylinder 54 is fixedly connected to the trapezoidal block 53, the release rod 52 is arranged on both sides of the bin body 51, the front end of the release rod 52 is provided with an inclined surface, and the telescopic block 4 is located on the movement path of the release rod 52.

[0030] In a preferred embodiment, rollers are respectively provided at the ends of the vertical top roller 34 and the horizontal top roller 42 , and a protrusion 531 is provided on the inclined surface of the trapezoidal block 53 , and a protrusion 531 is also provided on the outer side of the roller at the lower end of the vertical top roller 34 .

[0031] Working principle: the driving cylinder 54 drives the bin body 51 to slide along the double-track slide groove on the bottom plate 1. When the bin body 51 moves toward one end of the right support 33, the release rod 52 first touches the roller on the horizontal top roller 42 and squeezes the horizontal top roller 42 to slide toward the right support 33. At this time, the inclined sliding block 41 supporting the discharge plate 31 moves synchronously and disengages from the discharge plate 31, and the bin body 51 continues to move. The roller of the vertical top roller 34 gradually turns from abutting against the short side of the trapezoidal block 53 to its inclined surface. The discharge plate 31 rotates along the rotating shaft by its own weight and the weight of the concrete bricks. When the discharge plate 31 tilts, the concrete bricks on the discharge plate 31 fall downward into the bin body 51. In addition, when the roller of the vertical top roller 34 touches the inclined surface of the trapezoidal block 53, the convex collision of the contact surfaces of the two produces vibration, thereby accelerating the sliding speed of the concrete bricks. In addition, a vibration motor 8 can be provided at the bottom of the discharge plate 31 to make the discharge plate 31 clean more thoroughly.

[0032] After the inclined surface of the release rod 52 passes over the roller on the horizontal top roller 42, the release rod 52 always keeps squeezing the horizontal top roller 42, and when the driving cylinder 54 drives the bin body 51 to move in the opposite direction, the inclined discharge plate 31 gradually returns to a horizontal state through the cooperation of the trapezoidal block 53 and the vertical top roller 34, and finally the inclined slide block 41 returns to its initial position under the elastic force of the horizontal spring 43. The bottom of the inclined slide block 41 is set to an inclined surface, which can ensure that the discharge plate 31 smoothly returns to its initial position without interference. This device can automatically unload materials while testing the strength of concrete bricks, clean up the broken concrete debris, thereby speeding up the detection efficiency and reducing the labor intensity of the staff.

It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
