Description

Technical Field

[0001] This utility model belongs to the technical field of flipping and demolding machines, specifically a flipping and demolding machine for precast concrete structures. Background Technology

[0002] The concrete precast component flipping and demolding machine is a specialized piece of equipment used in the production of precast concrete components. It achieves efficient separation of molds and components through a combination of mechanical flipping and demolding processes. Its applications are wide-ranging, covering the large-scale production of precast components for prefabricated buildings (such as precast wall panels and floor slabs), municipal engineering (such as pipe corridors and curbs), and water conservancy facilities. It can effectively improve production efficiency, reduce labor intensity, and at the same time ensure the stability of component quality and the safety of the production process. It is an important piece of equipment in modern precast component production lines. An existing patent (publication number: CN222096498U) discloses a precast component flipping and demolding machine. This machine incorporates an adjustable clamping structure, which, through a transmission mechanism, allows for adjustment based on the size of the precast component. This design makes the clamping position more convenient to use, as the machine utilizes a rotating motor within the adjustable clamping structure to adjust the clamping position according to the size of the precast component. However, this flipping and demolding machine, which uses a clamping method for positioning and flipping, is slow, adding an extra clamping step and thus reducing demolding efficiency and impacting the construction cycle. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a concrete precast component flipping and demolding machine, which effectively solves the problem that the existing flipping and demolding machine uses a clamping method for positioning and flipping, which is slow and adds a clamping process, thereby reducing demolding efficiency and affecting the construction cycle.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a precast concrete structure flipping and demolding machine, comprising a pad, a frame fixedly installed at one end of the top of the pad, a conveyor belt installed inside the frame, a placement platform fixedly installed at the other end of the top of the pad, a support frame fixedly installed on one side of the top of the pad, a servo motor fixedly installed at the upper end of one side of the support frame, a flipping component provided at the output end of the servo motor, three molds placed on the flipping component, precast concrete slabs cast inside the molds, and two through holes opened on one side of each of the three molds. When the servo motor operates, it drives the flipping and demolding component to flip the molds and precast concrete slabs through a transmission component. A support plate is fixedly installed on the upper part of one end of the frame through two support columns, and a demolding component is provided on the support plate. The demolding component can be inserted into the two through holes to push out the precast concrete slabs inside the molds.

[0005] Preferably, the demolding assembly includes an electric push rod fixedly installed on the top of the support plate, with the transmission end of the electric push rod extending downward to the lower part of the support plate and having a push head fixedly installed thereon.

[0006] Preferably, a slide rod is fixedly installed on one side of the push head via a connecting strip, and a sliding sleeve is fitted on the surface of the slide rod, with one side of the sliding sleeve fixedly connected to the support plate.

[0007] Preferably, the flipping assembly includes a drive gear fixedly installed at the output end of the servo motor, a driven gear meshing with the circumferential surface of the drive gear, one side of the driven gear being rotatably connected to the support frame via a rotating seat, a shaft being fixedly installed on the other side of the driven gear, a bushing being rotatably installed on the surface of the shaft, a positioning frame being fixedly installed on the surface of the bushing, the bottom of the positioning frame being fixedly connected to the pad, and one side of the drive gear being rotatably connected to the positioning frame via a rotating seat.

[0008] Preferably, a flipping frame is fixedly installed at one end of the shaft, and four placement slots are equidistantly opened on the surface of the flipping frame in a ring, with the three molds respectively inserted into the three placement slots.

[0009] Preferably, a bearing seat is rotatably mounted on one side of the flipping frame, a fixing frame is fixedly mounted on one end of the bearing seat, and the bottom of the fixing frame is fixedly connected to the pad.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator places the mold and precast concrete slab on the conveyor belt, and then the conveyor belt transports the mold and precast concrete slab to the placement slot on the tilting frame; then the servo motor is controlled to drive the drive gear to rotate, the drive gear drives the shaft to rotate through the driven gear, and the shaft rotates to drive the tilting frame to rotate, which in turn drives the mold and precast concrete slab to rotate to the bottom of the support plate; Then, the operator starts the electric push rod to drive the push head down. When the push head moves down, it drives the slide rod to slide along the inside of the slide sleeve through the connecting strip, which increases the stability of the push head when it moves. When the push head moves down, it will insert into the mold through the through hole, thereby pushing the precast concrete slab onto the placement table. Then the mold is pulled out, thus quickly completing the demolding. This makes it possible for this flipping demolding machine to directly place and flip the mold without clamping it, thereby reducing the number of processes and improving demolding efficiency.

[0015] In use, the operator places the mold 19 and the precast concrete slab 20 on the conveyor belt 3, and then the conveyor belt 3 transports the mold 19 and the precast concrete slab 20 to the tilting assembly. The operator controls the servo motor 6 to drive the tilting assembly to rotate, so that the tilting assembly drives the mold 19 and the precast concrete slab 20 to rotate under the support plate 9. Then, the operator controls the demolding assembly to push the precast concrete slab 20 onto the placement platform 4, and then pulls out the mold 19, thereby quickly completing the demolding. This means that the demolding machine does not need to clamp the mold 19, and can directly place and flip the mold 19, thereby reducing the number of steps and improving the demolding efficiency.

[0016] The flipping assembly includes a drive gear 10 fixedly mounted on the output end of the servo motor 6. A driven gear 11 is meshed with the circumferential surface of the drive gear 10.

A fixing frame 17 is fixedly installed at one end of the bearing seat 16. The bottom of the fixing frame 17 is fixedly connected to the pad 1.

[0019] When the shaft 12 rotates, it drives the tilting frame 15 to rotate, which in turn drives the mold 19 and the precast concrete slab 20 to tilt under the support plate 9.

[0020] The demolding assembly includes an electric push rod 22 fixedly installed on the top of the support plate 9. The transmission end of the electric push rod 22 extends downward to the lower part of the support plate 9 and is fixedly installed with a push head 23.
