Description

Technical Field

[0001] The invention relates to the field of prefabricated concrete component production, and in particular to a double-sided superimposed prefabricated concrete component production system. Background Art

[0002] In the prior art, the production of double-sided laminated concrete precast components requires the use of a large-scale integrated lifting, clamping and flipping equipment. Before the laminating operation, the side mold of the concrete sheet (hereinafter referred to as the B-page concrete sheet) that has been poured with the first side of concrete and completed the initial curing and has a certain strength is removed, and the B-page concrete sheet is pressed tightly on the formwork (hereinafter referred to as the B mold) using a pressure strip. At the same time, the formwork is fixedly clamped on the lifting, clamping and flipping integrated equipment, and then the B-page concrete sheet is lifted and flipped 180 degrees together with the B mold, and transferred to another plain concrete sheet (hereinafter referred to as the A-page concrete sheet) that has just completed concrete pouring, so that the exposed connecting steel bars on the B-page concrete sheet enter the already poured A-page concrete sheet plain concrete, forming a double-sided laminated concrete component composed of an inner and outer two-page concrete thin-wall structure connected by steel bars. The concrete component carried on the formwork that has completed the secondary laminating operation is subjected to the second curing, so that the later poured A-page concrete sheet also reaches a strength that can be demolded to obtain the final double-sided laminated concrete component. This process requires the use of large-scale integrated lifting, clamping and flipping equipment. During the flipping process, a pressure plate needs to be installed to press the first concrete sheet against the mold table, and at the same time, the mold table is clamped to flip the mold table and the first concrete sheet. After flipping, the pressure plate needs to be removed. The overlapping operation process is complicated. The B mold must wait until the B page concrete sheet completes the overlapping operation, and then it can be flipped back with the lifting, clamping and flipping integrated equipment before entering the next cycle. The production efficiency of the overlapping mold is low, and the large-scale lifting, clamping and flipping integrated equipment must be flipped in sequence. Before turning, the clamping and insertion plates of the mold fix the B-page concrete sheet on the mold table, and the mold is lifted and turned over. The pulling and pressing plates release the fixation of the B-page concrete sheet on the mold table after overlapping. The mold is turned back after overlapping, and the mold is released from the clamp after turning back. Its operation mode is that one device is carried out serially, and the production efficiency is low. The large-scale integrated lifting, clamping and turning equipment has a complex structure, a large number of mechanical parts, a high equipment cost, a large amount of maintenance work, and complex equipment is prone to failure, resulting in production stoppages. The equipment is heavy and has high operating energy consumption. Summary of the invention

[0003] In order to solve the above problems, the present invention discloses a production system for double-sided laminated prefabricated concrete components.

[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:

[0005] A double-sided overlapping concrete prefabricated component production system, which includes a longitudinal mold conveying device, and also includes two or more mold transverse moving devices arranged between any two groups of parallel mold longitudinal moving devices for transversely moving the mold from one group of mold longitudinal conveying devices to another group of mold longitudinal conveying devices. It also includes a concrete pouring vibration table arranged in a channel for longitudinally conveying the mold along the mold longitudinal moving devices. It also includes a component lifting device, and it also includes a turning system arranged below the travel range of the component lifting device. It also includes a superimposed vibration table arranged below the travel range of the component lifting device, and it also includes a curing kiln.

[0006] When in use, the double-sided overlapping concrete precast component mold (hereinafter referred to as the A-page mold) arrives above the concrete pouring vibration table under the coordinated driving of the mold longitudinal conveying device and the mold transverse moving device. After the elevated concrete self-feeding hopper picks up concrete from the concrete mixing station, it runs to the top of the distribution boom at the pouring point and puts the carried concrete into the distribution boom. The distribution boom puts concrete into the A mold. At this time, there is only plain concrete but no steel cage in the A mold. The concrete in the A mold is hereinafter referred to as the A-page concrete slab. The A-page mold that has been poured with plain concrete arrives on the overlapping vibration table driven by the mold longitudinal conveying device to wait for secondary overlapping operations.

[0007] While the A mold is carrying out the above-mentioned operation procedure, another mold (hereinafter referred to as the B page mold) carries a concrete component with exposed steel bars (hereinafter referred to as the B page concrete slab) that has undergone curing and reached the demoulding strength and is ready to be connected to the A page concrete slab to complete the curing operation.

[0008] When a turnover system consisting of an online mold turnover device and a component turnover device is used, the B mold carrying the B-page concrete slab is driven in coordination with the mold longitudinal conveying device and the mold transverse moving device to reach the top of the online mold turnover device, the online mold turnover device is actuated to flip the B mold to an angle at which the B-page concrete slab in the B mold can be lifted and moved transversely in a vertical state after being lifted, the component lifting device vertically takes the B-page concrete slab out of the B mold and puts it onto the component turnover device, the component turnover device is actuated to flip the B-page concrete slab from a vertical state to a state with exposed steel bars facing downward, the component lifting device horizontally lifts the B-page concrete slab from the component turnover device and moves it to the top of the A mold on the stacking vibration table, the component lifting device puts the B-page concrete slab onto the A mold, and under the deadweight of the B-page concrete slab and the vibration of the stacking vibration table, the exposed steel bars of the B-page concrete slab penetrate into the plain concrete in the A mold to complete the secondary stacking.

[0009] When a flipping device that can flip the component 180 degrees at one time is used, the B mold carrying the concrete slab containing exposed steel bars that has undergone concrete pouring and curing and has a certain strength arrives under the component lifting device, the B-page concrete slab in the B mold is lifted horizontally and placed on the 180-degree flipping device that can flip the component 180 degrees at one time, the 180-degree flipping device is activated to flip the B-page concrete slab 180 degrees to a state with the exposed steel bars facing downward, the component lifting device lifts the B-page concrete slab from the 180-degree flipping device and runs it to the top of the A mold on the stacking vibration table, the component lifting device places the B-page concrete slab on the top of the A mold, and under the deadweight of the B-page concrete slab and the vibration of the stacking vibration table, the exposed steel bars of the B-page concrete slab penetrate into the plain concrete in the A mold to complete the secondary stacking.

[0010] The B mold of the B-page concrete slab is hoisted out and runs to the concrete pouring vibration table under the coordinated driving of the mold longitudinal conveying device and the mold transverse moving device. After completing the corresponding mold cleaning, side mold assembly, mold release agent coating and steel cage installation operations, it arrives at the concrete pouring vibration table for concrete pouring and vibration operations, and is then sent to the curing kiln for curing.

[0011] The A mold carrying the component that has completed the secondary overlap is sent to the curing kiln for curing by the mold longitudinal conveying device. When the concrete in the A mold reaches the demoulding strength, it leaves the curing kiln and reaches the demoulding position on the mold longitudinal conveying channel for demoulding and lifting operations under the coordinated driving of the mold longitudinal conveying device and the mold transverse moving device, thereby obtaining a double-sided overlapping concrete prefabricated component.

[0012] The above operations are repeated, and the double-sided laminated concrete precast component production system continuously produces double-sided laminated concrete precast components.

[0013] The beneficial effects of the present invention are as follows: the structural design of the present invention is reasonable and ingenious, avoiding the serial operation of using complex large-scale lifting, clamping and turning integrated equipment. The lifting and turning operations are respectively implemented by independently operating component lifting equipment and turning equipment. During the lifting and turning process, the B-page concrete sheet does not need to be fixed on the mold table. After the B-page concrete sheet is demolded, the B-page mold can be transferred to the next operation point. There is no need to wait for the superposition operation to be completed before entering the next cycle operation. The double-sided superimposed concrete precast components can be produced efficiently, and there is no need to insert and remove the pressure plate operation, which simplifies the operation. Its operation mode is that multiple independently operating equipment are carried out in parallel, with high production efficiency. The independently operating turning equipment and component lifting equipment have a small number of mechanical parts and a low manufacturing cost. The simple independently operating equipment has a low failure rate and a small amount of maintenance work. The independently operating turning equipment and component lifting equipment have a small dead weight and low operating energy consumption.

The concrete distribution device 12 feeds concrete into the A-page mold. At this time, there is only plain concrete in the A-page mold without a steel cage. The concrete in the A-page mold is hereinafter referred to as A-page thin plate concrete.

[0043] The A-page mold that has been poured with plain concrete is driven by the mold longitudinal conveying device located in the pouring operation area 4 and the secondary overlapping operation area 5 to reach the top of the overlapping vibration table 18 located in the secondary overlapping operation area 5, waiting for the secondary overlapping operation;

[0044] When a turnover system consisting of an online mold turnover device 16 and a component turnover device 17 is used, the mold longitudinal conveying devices in the first empty mold operation area and the secondary stacking operation area drive the B page mold that has completed the corresponding operations before demoulding and lifting to the top of the online mold turnover device 16 located in the secondary stacking operation area 5, and the mold fastening device 31 acts to fix the B page mold on the turnover table 34, and the turnover drive device 32 drives the turnover table 34 to rotate around the rotating shaft 33 with the mold and the B page concrete sheet in the mold to an angle that allows the B page concrete sheet to be vertically demoulded and lifted and to move horizontally in a vertical state after lifting, and then stops at the secondary stacking The component lifting device 15 of the overlapping operation area 5 takes the B-page concrete sheet out of the B-page mold and puts it on the component turning device 17 located in the secondary overlapping operation area 5. The turning drive device 32 of the online mold turning device 16 drives the turning table 34 to rotate and reset to wait for the next operation. When the B-page concrete sheet is put into the component turning device 17, the turning drive device 32 of the component turning device 17 drives the turning table 34 to rotate around the rotating shaft 33 with the B-page concrete sheet, turning the B-page concrete sheet from a nearly vertical state to a horizontal state with the exposed steel bars facing downward.

The concrete sheet rotates 90 degrees around the rotation axis 33, and the turning drive device 32 of the 90-180 degree L-shaped turning frame 38 drives the 90-180 degree L-shaped turning frame 38 to rotate the B-page concrete sheet around the rotation axis 33 by 90 degrees, so that the B-page concrete sheet is in a horizontal state with exposed steel bars facing downward, and the component lifting device lifts the B-page concrete sheet horizontally, ready to be placed on the A-page concrete sheet located on the superimposed vibration table 18, and then the turning drive device 32 of the 180 degree turning device 27 drives the 0-90 degree L-shaped turning frame 37 and the 90-180 degree L-shaped turning frame 38 to rotate and reset to wait for the next operation;

The superposition vibration table 18 vibrates, driving the A-page mold located on the superposition vibration table 18 to vibrate, so that the exposed steel bars of the B-page concrete slab penetrate into the plain concrete in the A-page mold to complete the secondary superposition. After the secondary superposition operation is completed, the component lifting device 15 is separated from the B-page concrete slab, and the mold longitudinal conveying device sends the A-page mold carrying the concrete component that has completed the secondary superposition to the curing kiln 14 located in the curing area 6 for curing;

[0046] While the A-page mold is performing the secondary overlapping operation, the B-page mold that has been demoulded leaves the secondary overlapping operation area 5 and enters the second empty mold operation area 2 under the drive of the mold longitudinal conveying device. Before entering the second empty mold operation area 2, the B-page mold performs corresponding empty mold operations before pouring, such as mold cleaning, applying mold release agent, installing steel cages and installing embedded parts;

[0047] The B-page mold that has completed the corresponding empty mold operation enters the first transverse movement area 3 under the drive of the mold longitudinal conveying device, and the mold transverse moving device 9 located in the first transverse movement area 3 moves the B-page mold to the starting position of the mold longitudinal conveying device corresponding to the pouring operation area 4, the secondary overlapping operation area 5, and the curing area 6;

[0048] The mold longitudinal conveying devices located in the pouring operation area 4, the secondary superposition operation area 5 and the curing area 6 drive the B-page mold to the top of the concrete pouring vibration table 13 in the pouring operation area 4, and the concrete placing device 12 puts concrete into the B-page mold, and the concrete pouring vibration table 13 located in the pouring operation area 4 works to make the concrete fully fill the mold cavity, and the concrete in the mold cavity is vibrated and exhausted to obtain a B-page concrete sheet containing exposed steel bars;

[0049] The B-sheet mold carrying the B-sheet concrete sheet containing exposed steel bars enters the curing area 6 under the drive of the mold longitudinal conveying device. When a planar curing kiln with a hollow insulation structure with doors at both ends straddling one group of the mold longitudinal moving channels is used, the insulation door at the kiln entrance end of the curing kiln 14 is opened, and the mold carrying concrete enters the curing kiln 14 under the action of the mold longitudinal moving device and continues to move longitudinally in the curing kiln 14. After the concrete reaches the demoulding strength, the insulation door at the kiln exit end of the curing kiln 14 is opened, and the mold is moved away from the curing kiln 14 by the mold longitudinal moving device. When a combined planar curing kiln with a side-opening door located on the outer side of one group of the mold longitudinal moving channels is used, the curing kiln 14 is opened. During kiln maintenance, the mold carrying concrete arrives outside a certain combined plane curing kiln unit door under the action of the mold longitudinal moving device, the heat-insulating door of the curing kiln unit is opened, and the mold transverse moving transport vehicle transports the mold carrying concrete into the curing kiln unit for placement. After the curing kiln unit is filled with molds, the heat-insulating door is closed for concrete curing. After the concrete in the mold reaches the demoulding strength, the heat-insulating door of the curing kiln unit is opened, and the mold transverse moving transport vehicle transports the mold carrying concrete out of the kiln and puts it onto the mold longitudinal moving device outside the curing kiln door. The mold is moved away from the curing kiln by the mold longitudinal moving device 14. When the in-situ entry and exit of the three-dimensional curing kiln is adopted, the The mold carrying concrete reaches below the stacker outside the three-dimensional curing kiln under the action of the mold longitudinal moving device, and the stacker lifts the mold and sends it into the kiln chamber of a certain three-dimensional curing kiln for curing. After the concrete in the mold reaches the demoulding strength, the stacker takes the mold out of the kiln chamber and puts it on the mold longitudinal moving device. The mold is moved away from the curing kiln 14 by the mold longitudinal moving device. When a three-dimensional curing kiln is used in which the mold straddling one group of the mold longitudinal moving channels is lifted and moved in the kiln, the mold carrying concrete reaches the lower part outside the three-dimensional curing kiln under the action of the mold longitudinal moving device, and the three-dimensional curing kiln lifting mechanism lifts the mold from the bottom of the three-dimensional curing kiln into the three-dimensional curing kiln, and the concrete in the mold is moved along the kiln. During the operation of the ascending channel, the transverse channel and the descending channel, the mold is cured to reach the demoulding strength. The three-dimensional curing kiln lifting mechanism puts the mold onto the mold longitudinal moving device, and the mold is moved away from the curing kiln 14 by the mold longitudinal moving device. The mold leaving the curing kiln 14 arrives at the first empty mold operation area 1 under the coordinated action of the mold longitudinal moving device and the mold transverse moving device 9. The mold carrying the double-layer laminated hollow component that has reached the demoulding strength is demoulded in the first empty mold operation area 1 to obtain a double-layer laminated hollow component finished product. The mold carrying the B-page concrete sheet continues to run to the secondary lamination operation area 5, waiting for the secondary lamination operation. After the concrete in the A-page mold that has completed the secondary lamination reaches the demoulding strength,The A-page mold and the concrete component carried by it leave the curing area 6 under the coordinated driving of the mold longitudinal conveying device and the mold transverse moving device 9, and arrive at the first empty mold operation work area 1, and perform the mold removal and lifting operation to obtain a double-sided overlapping concrete prefabricated component;

[0050] The above process is repeated, and the double-sided composite concrete precast component production system continuously produces double-sided composite concrete precast components.

[0051] The structural design of the present invention is reasonable and ingenious, avoiding the serial operation of using complex large-scale lifting, clamping and flipping integrated equipment. The lifting and flipping operations are respectively implemented by independently operating component lifting equipment and flipping equipment. During the lifting and flipping process, the B-page concrete sheet does not need to be fixed on the mold table. After the B-page concrete sheet is demolded, the B-page mold can be transferred to the next operation point, and the next cycle operation can be entered without waiting for the completion of the overlapping operation. The double-sided overlapping concrete precast components can be produced efficiently without the need to insert and remove the pressure plate operation, which simplifies the operation. Its operation mode is that multiple independently operating devices are carried out in parallel, with high production efficiency. The independently operating flipping equipment and component lifting equipment have a small number of mechanical parts and a low manufacturing cost. The simple independently operating equipment has a low failure rate and a small amount of maintenance work. The independently operating flipping equipment and component lifting equipment have a small dead weight and low operating energy consumption.
