Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated components of construction engineering, and more specifically, to a concrete prefabricated component flattening device. Background Art

[0002] During construction, in addition to the concrete structures built and poured on site, prefabricated concrete components are sometimes used to facilitate construction by workers and speed up construction. When prefabricated concrete components are produced, there will be certain unevenness on the surface, which needs to be smoothed. In order to improve the low efficiency of manual smoothing, smoothing equipment is generally used for smoothing.

[0003] The common flattening equipment has a simple structure. After the concrete precast component is fixed, the flattening material is driven to move repeatedly for flattening through the power structure. However, it is difficult to flatten the precast component completely in a single flattening, and it needs to be flattened repeatedly. The common power structure is composed of a motor, a screw and a moving block. When working, the servo motor needs to rotate repeatedly, so that the screw drives the flattening equipment to move repeatedly for flattening. There will be an obvious pause when changing direction, and it is impossible to move repeatedly smoothly and at high speed, and it is impossible to maintain high efficiency. Moreover, during the flattening process, the concrete powder rubbed off the concrete precast component will be scattered on the surface of the precast component, affecting the contact between the flattening equipment and the precast component, thereby affecting the flattening effect. In addition, in order to achieve an ideal flattening effect, flattening materials of different coarseness and fineness are often required. Therefore, during the flattening process, the flattening material needs to be replaced. In order to ensure the stability of the flattening material, the common flattening equipment will adopt fixing methods such as bolt fixing, which is troublesome to disassemble and affects the processing efficiency.

The driving motor 4 drives the rotating disk 5 to rotate, thereby driving the eccentric shaft 6 to make a circular motion. The eccentric shaft 6 cooperates with the rotating member 8 to drive the transmission rod 7 to move, and the transmission of the transmission rod 7 drives the mounting frame 2 to move, so that the mounting frame 2 moves repeatedly with the flattening block 3.

[0034] See also Figure 3 As an implementation method for installing the flattening block 3: the flattening block 3 is provided with a mounting column 13, the mounting frame 2 is provided with a mounting groove 14, the mounting column 13 cooperates with the mounting groove 14, the mounting frame 2 has mounting openings 15 at both ends, the mounting column 13 is provided with a support opening 16, the mounting opening 15 is provided with a support block 17, and the support block 17 cooperates with the support opening 16.

[0035] Specifically, when installing the flattening block 3, first pull out the support block 17 to empty the inside of the installation groove 14, and then insert the installation column 13 into the installation groove 14. At this time, the support opening 16 will be aligned with the installation opening 15, and the support block 17 is inserted from the installation opening 15, passes through the support opening 16 and then passes out from the installation opening 15 at the other end. At this time, the support block 17 passes through the installation opening 15 and penetrates the mounting frame 2.

After alignment, the positioning column 20 will be inserted into the positioning hole 18, and the positioning column 20 will be restricted by the positioning shell 19, thereby fixing the position of the support block 17.

[0039] Specifically, the pressure spring 21 applies a thrust to move the positioning column 20 out of the positioning shell 19, so that the positioning column 20 can be stably matched with the support block 17 to prevent the positioning column 20 from slipping out of the positioning port 18 by itself. When the positioning column 20 needs to be moved, the positioning column 20 is pulled up by the pull rod 22 to prevent the positioning column 20 from affecting the movement of the support block 17.

[0041] Specifically, the mounting frame 2 cooperates with the sliding frame 23 through a limit slider 24 and a rolling wheel 25. When the mounting frame 2 moves, the limit slider 24 cooperates with the sliding frame 23 to limit the moving direction of the mounting frame 2.

A positioning bolt 27 is provided on the eccentric shaft 6. A positioning groove 28 is opened in the adjusting groove 26. There are multiple positioning grooves 28, which are arranged and distributed along the adjusting groove 26 at equal intervals.

[0043] Specifically, the positioning bolt 27 is loosened to make the positioning bolt 27 leave the positioning groove 28, thereby releasing the restriction on the eccentric shaft 6, and adjusting the position of the eccentric shaft 6 in the adjusting groove 26, thereby adjusting the distance between the eccentric shaft 6 and the center of the rotating disk 5, so that the rotation amplitude of the eccentric shaft 6 meets the repeated movement range of the flattening process. After adjusting the eccentric shaft 6, tighten the positioning bolt 27 to insert the positioning bolt 27 into the positioning groove 28 to fix the position of the eccentric shaft 6.

[0044] Please refer to Figure 2 As a further implementation of the supporting mechanism: a supporting cylinder 29 is provided in the middle of the frame 1, and a supporting platform 30 is provided on the supporting cylinder 29.

[0045] Specifically, the precast concrete component is placed on the support platform 30 , and the support cylinder 29 provides a supporting force so that the support cylinder 29 supports the support platform 30 to work, and the support cylinder 29 can drive the support platform 30 to rise, so that the precast concrete component contacts the flattening block 3 .

[0046] Please refer to Figure 2 As a further implementation of the supporting mechanism: fixed cylinders 31 are provided at both ends of the supporting platform 30 , and a fixed plate 32 is provided at the output end of the fixed cylinder 31 .

[0047] Specifically, the fixing cylinder 31 provides power so that the fixing plate 32 cooperates to clamp and fix the prefabricated concrete components on the support platform 30 .

[0048] In summary, when the overall device is in use or running:

[0049] When the precast concrete component is flattened, the precast concrete component is placed on the support platform 30, and the support cylinder 29 provides supporting force, and the fixing cylinder 31 provides power, so that the fixing plate 32 cooperates to clamp and fix the precast concrete component on the support platform 30, so that the support cylinder 29 supports the support platform 30 to work, and the support cylinder 29 can drive the support platform 30 to rise, and the precast concrete component is adjusted to a suitable height by adjusting the working condition of the support rod, so that it contacts the flattening block 3, and under the support of the frame 1, each device works stably, and the positioning bolt 27 is loosened to make the positioning bolt 27 leave the positioning groove 28, and the restriction on the eccentric shaft 6 is released. According to the area of ​​the precast concrete component, the repeated movement distance of the flattening block 3 is determined, and the position of the eccentric shaft 6 in the adjusting groove 26 is adjusted, thereby adjusting the distance between the eccentric shaft 6 and the center of the rotating disk 5, so that the rotation amplitude of the eccentric shaft 6 meets the flattening processing The range of repeated movement, after adjusting the eccentric shaft 6, tighten the positioning bolt 27, so that the positioning bolt 27 is inserted into the positioning groove 28, fix the working position of the eccentric shaft 6, start the driving motor 4, and the driving motor 4 drives the rotating disk 5 to rotate, thereby driving the eccentric shaft 6 to make a circular motion, and the eccentric shaft 6 cooperates with the rotating member 8 through the eccentric shaft 6 to drive the transmission rod 7 to move, and the mounting frame 2 is driven to move through the transmission rod 7. The mounting frame 2 cooperates with the sliding frame 23 through the limiting slider 24 and the rolling wheel 25. When the mounting frame 2 moves, the limiting slider 24 will cooperate with the sliding frame 23 to limit the moving direction of the mounting frame 2, so that the mounting frame 2 drives the flattening block 3 to move repeatedly for flattening processing, and under the transmission of the limiting slider 24, the rolling wheel 25 cooperates with the sliding frame 23 to provide support and limiting capacity for the mounting frame 2, and the rolling wheel 25 will make the movement of the mounting frame 2 smoother, which is convenient for flattening processing.

[0050] During the flattening process, the collecting pump 11 is started to provide negative pressure through the collecting pump 11 to provide suction for the dust hood 9. The dust hood 9 will move with the flattening block 3. When moving along the path of the flattening block 3, it will absorb concrete debris on the path of the flattening block 3 and clean the processing surface of the prefabricated component to avoid the debris affecting the subsequent contact between the flattening block 3 and the prefabricated component, thereby ensuring the flattening effect. The sucked debris will enter the collection box 10 along the collection pipe 12. The collection box 10 is similar to the common dust collection box on the market, and has a built-in filtering structure inside, so that the debris remains in the collection box 10, and the concrete material is recovered through the collection box 10.

[0051] When performing the flattening process, according to different flattening requirements, flattening devices of different coarseness and fineness need to be used, or when the original flattening block 3 is damaged and the flattening block 3 needs to be replaced, the positioning column 20 is pulled up by pulling the pull rod 22 to make the positioning column 20 slide out of the positioning port 18, release the restriction on the support block 17, and then pull out the support block 17, release the restriction on the mounting column 13, and finally pull out the mounting column 13 from the mounting groove 14, remove the original flattening block 3, and then insert the mounting column 13 of the new flattening block 3 into the mounting groove 14, so that the support port 16 will be aligned with the mounting port 15, and then the support block 17 is installed from one end. The support block 17 is inserted into the mounting opening 15 so that the support block 17 passes through the support opening 16 and then passes out from the mounting opening 15 at the other end. The position of the support block 17 is adjusted so that the positioning opening 18 of the support block 17 is aligned with the positioning column 20. Then the pull rod 22 is released. Under the action of the pressure spring 21, power is provided to the positioning column 20 so that the positioning column 20 slides along the positioning shell 19 and is inserted into the positioning opening 18. At this time, the positioning column 20 is restricted by the positioning shell 19, thereby restricting the position of the support block 17, and the support block 17 passes through the mounting frame 2 through the mounting opening 15. Under the support of the mounting frame 2, it cooperates with the support opening 16 to support the mounting column 13.
