Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing devices, in particular to a concrete prefabricated part turning device. Background Art

[0002] Prefabricated concrete technology accelerates on-site construction, significantly reduces environmental impact and traffic disruption at the bridge site, ensures project quality, and reduces bridge lifecycle costs. Its technical and economic advantages are increasingly recognized by the bridge industry worldwide. With the advancement of my country's industrialization and rising labor costs, prefabrication technology is an inevitable trend in the future development of the construction industry.

[0003] Prefabrication and assembly technology relies on precast concrete parts. After curing, these parts must undergo demolding, which involves sequentially removing the pallet, flipping the mold, and removing it from the mold. Current flipping devices are prone to incomplete flipping, excessive flipping, and other unsafe conditions, resulting in a rollover. This results in a poor overall mechanization level.

[0026] Example 1

[0027] like Figure 1-4 As shown, this embodiment provides a concrete precast part flipping device, including a support frame 1, a driving mechanism 2 and a flipping frame, the driving mechanism 2 is installed on the support frame 1, and is used to drive the flipping frame to rotate; at least three guide rollers 3 are provided on opposite sides of the support frame 1, and the flipping frame is located in the support frame 1 and supported on the guide rollers 3; the flipping frame includes a first flipping disc 4, a second flipping disc 5, a third flipping disc 6 and a frame body 7, the first flipping disc 4, the second flipping disc 5 and the third flipping disc 6 are fixedly connected as a whole through the frame body 7, and the frame body 7 is provided with upper rollers 8 and lower rollers 9 parallel to each other, and a limited material channel 12 is formed between the upper rollers 8 and the lower rollers 9.

[0028] The flip frame is mounted on the support frame 1 via guide rollers 3. These guide rollers 3 guide the flip frame's tilting angle, preventing deviation and improving its accuracy. Furthermore, they support the flip frame, enhancing its stability on the support frame 1. A material limiting channel 12 is formed between the parallel upper and lower rollers 8 and 9. This channel limits the mold's position, and the drive mechanism 2 then drives the flip frame to rotate. During rotation, the upper and lower rollers 8 and 9, along with the frame 7, cooperate to prevent the mold from falling out of the frame, providing a protective limit and enhancing flip safety.

[0029] The first and third reversible discs 4 and 6 are supported on guide rollers 3 on either side of the support frame 1. One of the three guide rollers 3 is located at the top of the support frame 1, while the other two are located on either side of the bottom of the support frame 1. This three-point support enhances the stability of the reversible frame. The first, second, and third reversible discs 4, 5, and 6 are each equipped with flanges 19 at their end edges. A groove 20 is formed between the flanges 19 at each end, and the guide rollers 3 are positioned within the grooves 20, further enhancing the stability of the reversible frame during reversal.

[0030] The height of the material limiting channel 12 is consistent with the height of the mold, and the mold is just clamped in the material limiting channel 12 to prevent the mold from moving and improve the stability of the mold in the material limiting channel 12.

[0031] In this embodiment, the upper roller conveyor 8 and the lower roller conveyor 9 each include a plurality of rollers, each of which is connected to a power mechanism. The power mechanism may be a hydraulic motor. After the flip is completed, the hydraulic motor drives the rollers to rotate, allowing the mold between the upper roller conveyor 8 and the lower roller conveyor 9 to be transported to the outside of the support frame 1, so that the next mold can be flipped, thereby increasing the flipping speed.

[0032] In this embodiment, the driving mechanism 2 is in transmission connection with the second flip plate 5 via a transmission member, and is used to drive the second flip plate 5 to rotate.

[0033] In this embodiment, the transmission member is a chain 10, and a sprocket 11 is connected to the drive mechanism 2. One end of the chain 10 is wound around the sprocket 11, and the other end of the chain 10 is sleeved on the second flip plate 5. The drive mechanism 2 is a motor, and the sprocket 11 is installed at the output end of the motor. When the motor is started, the motor drives the sprocket 11 to rotate, and the sprocket 11 drives the chain 10 to rotate. The chain 10 drives the second flip plate 5 to rotate, realizing the rotation of the flip frame, so that the mold opening is downward.

[0034] In this embodiment, a feeding mechanism is provided on the feeding side of the limiting channel 12. The feeding mechanism comprises a feeding frame 13 and a push plate 14 mounted on the feeding frame 13. The working surface of the feeding frame 13 is at the same height as the top surface of the horizontal lower roller 9. The mold with its opening facing upward is transported to the feeding frame 13, where the push plate 14 pushes the mold toward the flipping frame until it is positioned between the upper and lower rollers 8, 9 of the flipping frame. This speeds up the feeding of the mold and improves flipping efficiency.

[0035] In this embodiment, a hydraulic cylinder 15 is provided on the feeding frame 13, and the driving end of the hydraulic cylinder 15 is connected to the push plate 14. The expansion and contraction of the hydraulic cylinder 15 can realize the reciprocating pushing of the mold without manual pushing, saving time and effort.

[0036] In this embodiment, a discharge mechanism is provided on the discharge side of the limiting channel 12. The discharge mechanism includes a discharge frame 16 and a plurality of discharge rollers 17 mounted on the discharge frame 16. The working surfaces of the discharge rollers 17 are at the same height as the top surface of the horizontal lower roller 9. Each discharge roller 17 is connected to a power station 18. After the mold between the upper roller 8 and the lower roller 9 is conveyed to the discharge frame 16, the power station 18 increases the power of the discharge rollers 17, causing the discharge rollers 17 to rotate and continue conveying the mold to the demolding station for demolding.

[0037] The working principle of a concrete precast part turning device is:

[0038] Initially, the upper and lower rollers 8 and 9 within the flip frame are horizontal. The mold, with its opening facing upward, is placed on the feed frame 13. Hydraulic cylinders 15 drive push plates 14 to move, allowing them to transport the mold into the material-limiting channel 12 formed by the upper and lower rollers 8 and 9. Drive mechanism 2 is activated, rotating sprocket 11, which in turn drives chain 10, which in turn drives second flip plate 5, ultimately rotating the flip frame until the mold opening within the flip frame faces downward.

[0039] The power mechanism provides power to the rolling rollers, causing them to rotate. The rotation of the rolling rollers causes the mold between the upper roller 8 and the lower roller 9 to move toward the discharge rack 16. At the same time, the power station 18 increases the power to the discharge roller 17, causing it to rotate. When the mold completely leaves the limiting channel 12, the power mechanism is turned off, and the discharge roller 17 continues to transport the mold to the demolding station for demolding.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
