[0002] The precast ribbed cavity floor system is a new type of floor form, suitable for large-span space structures. Since it uses cavity components, it is convenient for assembled installation, simple in construction and short in construction period. In the prior art, the movable core mold needs to be manually loaded and unloaded, lacking automatic core mold taking, which is rather inconvenient.

[0003] For example, a manufacturing equipment for precast ribbed cavity slabs disclosed in the utility model patent with the application number 201720938675.X includes a movable core mold, a traction device, a bottom mold, side molds and end molds. The precast ribbed cavity slab includes a ribbed cavity slab, two longitudinal side ribs, two transverse end ribs, at least one intermediate transverse rib and at least 2 closed cavities. The cavity is composed of a movable core mold and a sealing plate sheet. The movable core mold is a tubular shape with one end open, and multiple sealing plate sheets are placed inside and can be output. After formwork support, the movable core mold is placed into the mold. First, a sealing plate sheet is output, then concrete is placed and compacted, and then the movable core mold is withdrawn and a sealing plate sheet is output, thus completing the production of the cavity. The remaining rib beam part can be cast in situ with concrete. The production of the entire cavity slab can be completed in the factory and assembled and installed at the construction site.

[0004] However, the above prior art has the problem that the movable core mold needs to be manually loaded and unloaded, and automatic core mold taking cannot be achieved, resulting in inconvenient operation, time-consuming and laborious. Summary of the Utility Model

[0005] The purpose of the utility model is to solve at least one technical problem in the background art, and provide a manufacturing equipment for precast ribbed cavity slabs.

[0006] To achieve the above purpose, the utility model provides a manufacturing equipment for precast ribbed cavity slabs, including:

[0007] An operating table, on the top surface of which there is a mold groove;

[0008] A movable core mold, supported on the top surface of the operating table;

[0009] A driving mechanism, driving the movable core mold to move into the mold groove for grouting and forming to form a ribbed cavity slab;

[0010] The driving mechanism includes: a mounting plate, a threaded rod, a motor, a transmission member and a push plate;

[0011] Both ends of the top of the operation table are fixedly installed with mounting plates. Between the two mounting plates, two spaced threaded rods are rotatably installed. One end of each of the two threaded rods penetrates through one side of the mounting plate and is installed with a motor. The two ends of the push plate are respectively installed with the transmission members, and the two transmission members are respectively screwed to the two threaded rods. The push plate is screwed to the threaded rods through the transmission members and reciprocally moves along the threaded rods under the drive of the motor;

[0012] The movable die core is fixedly installed on the bottom surface of the push plate.

[0013] According to one aspect of the present invention, corner plates are provided on one side of the mold groove away from the movable die core and on the two sides adjacent to the one side. Two side ribbed bars are provided in the mold groove, and the two side ribbed bars are located on both sides of the movable die core that has moved into the mold groove.

[0014] According to one aspect of the present invention, the transmission member includes a movable sleeve, a limiting ring body and a guide rail bar. Two movable sleeves are respectively slidably installed at the two ends of the push plate. The top and bottom of the two movable sleeves are integrally processed with the guide rail bars. The surface of the guide rail bar is slidably connected to the hole wall of the corresponding through hole of the push plate, and the inner wall of the movable sleeve is screwed to the threaded rod.

[0015] According to one aspect of the present invention, two spaced grooves are opened at the bottom of the push plate, and pulleys are installed inside the two grooves. A strip-shaped groove for the pulley to slide is opened on the top surface of the operation table.

[0016] According to one aspect of the present invention, a fixed seat is fixedly installed on the top of the push plate, and the fixed seat is made of metal.

[0017] According to one aspect of the present invention, a controller for controlling the two motors is installed at the bottom of the operation table.

[0018] According to one aspect of the present invention, a storage box is fixedly installed at the bottom of the operation table, and four support columns are fixedly installed at the bottom of the operation table.

[0019] According to one aspect of the present invention, a sliding groove for the movable die core to slide is opened on the top surface of the operation table.

[0020] According to the solution of the present utility model, the present utility model uses a controller to start a motor to drive two threaded rods to rotate simultaneously. After the threaded rods drive the movable sleeves to slide a certain distance, the push plate is pushed to move by the abutment of the limit ring body and the push plate. The push plate can drive the bottom movable die core to move to the die groove at the top of the operating table. Place the corner plate in the die groove and inject the slurry. The slurry fills the die groove. After curing, a precast ribbed cavity slab is formed. When the ribbed cavity slab is demolded, first use a hammer to strike the push plate to separate the push plate and the movable die core from the formed ribbed cavity slab in the die groove. Since the push plate can move a certain distance on the movable sleeve, this distance is reserved for the movement of the push plate. This can ensure that the movable die core is first driven to move by moving the push plate. After confirming that the movable die core has been separated from the cast ribbed cavity slab, after confirmation of separation, the motor is used to drive the threaded rod to drive the transmission member and the push plate to move to remove the movable die core from the ribbed cavity slab. This can effectively avoid problems such as the motor being burned out caused by the difficulty of removing the movable die core that is in contact with the cast ribbed cavity slab when directly using the motor to drive the threaded rod to drive the push plate and the movable die core to move.

[0021] According to the solution of the present utility model, the present utility model can effectively solve the problem that the movable die core needs to be manually operated for loading and unloading, and the lack of automatic die core removal makes the operation inconvenient. It makes the manufacturing of precast ribbed cavity slabs more convenient and fast, effectively improves the efficiency of manufacturing precast ribbed cavity slabs, and is suitable for batch and rapid production.

The term "based on" is to be construed as "at least partially based on". The terms "an embodiment" and "one embodiment" are to be construed as "at least one embodiment".

[0026] Such as Figure 1 、 Figure 2 and Figure 3As shown, in this embodiment, the manufacturing equipment for precast ribbed cavity slabs includes:

[0027] An operating table 1, on the top surface of which there is a mold groove 2;

[0028] A plurality of corner plates 3 arranged at the top edge of the mold groove 2, and two side rib reinforcements 4 arranged in the mold groove 2;

[0029] A moving die core 5 arranged on the top surface of the operating table 1, and a driving mechanism 6 installed on the top of the operating table 1 for driving the moving die core 5 to move;

[0030] The driving mechanism 6 includes a mounting plate 61, a threaded rod 62, a motor 63, a transmission member 64 and a push plate 65. Mounting plates 61 are fixedly installed on both sides of the top of the operating table 1. Two threaded rods 62 are rotatably installed between the two mounting plates 61. One end of each of the two threaded rods 62 penetrates through one side of the mounting plate 61 and is installed with a motor 63. A push plate 65 is fixedly installed on the top of the moving die core 5. Transmission members 64 are respectively installed at both ends of the push plate 65. The inner parts of the two transmission members 64 are respectively threadedly connected to the surfaces of the two threaded rods 62.

[0031] The transmission member 64 includes a movable sleeve 641, a limiting ring body 642 and a guide rail bar 643. Two movable sleeves 641 are slidably installed inside the push plate 65.

The surface of the guide rail bar 643 is slidably connected to the hole wall of the corresponding through hole of the push plate 65. The inner wall of the movable sleeve 641 is threadedly connected to the surface of the threaded rod 62;

[0032] In this embodiment, the controller 8 is used to start the motor 63 to drive the two threaded rods 62 to rotate simultaneously. After the threaded rods 62 drive the movable sleeves 641 to slide a certain distance, the push plate 65 is pushed to move by the abutment of the limit ring body 642 and the push plate 65. Then, the push plate 65 can drive the bottom movable die core 5 to move to the mold groove 2 at the top of the operating table 1. The corner plate 3 is placed in the mold groove 2, and slurry is injected. After the slurry fills the mold groove 2 and cures, a precast ribbed cavity slab is formed. When the ribbed cavity slab is demolded, first, the push plate 65 is struck with a hammer to make the push plate 65 drive the movable die core 5 to separate from the formed ribbed cavity slab in the mold groove 2. Since the push plate 65 can move a certain distance on the movable sleeve 641, this distance is reserved for the movement of the push plate 65. In this way, it can be ensured that the movable die core 5 is first driven to move by moving the push plate 65.

[0036] Furthermore, in this embodiment, the controller 8 is used to control the two motors 63, and the two motors 63 are synchronous motors.

[0037] Furthermore, in this embodiment, two grooves 9 are opened at the bottom of the push plate 65, and pulleys 10 are installed inside both of the two grooves 9. A strip-shaped groove 11 for the pulley 10 to slide is opened at the top of the operating table 1;

[0038] It should be noted that the movement of the push plate 65 will drive the pulley 10 at the bottom groove 9 to move, and the strip-shaped groove 11 at the top of the operating table 1 is adapted to the pulley 10, which makes the movement of the push plate 65 more stable.

[0039] Furthermore, in this embodiment, a storage box 12 is fixedly installed at the bottom of the operating table 1, and four support columns 13 are fixedly installed at the bottom of the operating table 1; the storage box 12 is provided for storing the materials for manufacturing the ribbed cavity slab, which is convenient for taking.
