[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0035] like Figure 1 As shown, a three-dimensional concrete prefabricated component production and maintenance cycle operation platform, the operation platform includes:

[0036] A pit, the pit comprising a first station 13, a second station 14, a third station 15 and a fourth station 16 for placing the fixed die table 11;

[0037] The first workstation 13 is arranged at the upper edge of one side of the pit and has a first roller group 4 that can be extended to the inner wall of the pit to place the fixed mold platform 11 when the first roller group 4 is extended;

[0038] The second workstation 14 is arranged at the upper edge of the pit on one side relative to the first workstation 13, and has a second roller group 5 that can be extended to the inner wall of the pit, so as to place the fixed mold platform 11 when the second roller group 5 is extended;

[0039] The third station 15 is arranged directly below the second station 14, and has a third roller group 6 for placing the fixed mold platform 11, and a first lifter 12 arranged at the bottom of the pit for lifting the fixed mold platform 11 to move between the second station 14 and the third station 15;

[0040] The fourth station 16 is arranged directly below the first station 13, and has a fourth roller group 7 for placing the fixed mold platform 11, and a second lifter 1 arranged at the bottom of the pit for lifting the fixed mold platform 11 to move between the first station 13 and the fourth station 16;

[0041] A retaining wall for isolating the third workstation 15 and the fourth workstation 16 is provided in the middle of the pit, and a sealing skirt 8 for isolating the first workstation 13 and the fourth workstation 16 is provided above the pit corresponding to the fourth workstation 16, so that the fourth workstation 16 forms a sealed curing room.

[0042] The pit area is adapted to the two fixed mold tables 11. At the same time, after the fixed mold tables 11 are placed on the first station 13 and the second station 14, the upper plane of the fixed mold tables 11 is flush with the ground or slightly higher than the ground, and the height is based on the convenience of workers to operate.

[0043] By constructing a semi-underground three-dimensional working space, four fixed mold tables 11 placement stations are set up at the positions of the original two fixed mold tables 11, and three fixed mold tables 11 are placed on the four stations, so as to increase the number of mold tables per unit area and increase the equipment production capacity.

[0044] In another optional embodiment of the present application, there are multiple sealing skirts 8, which are distributed in the circumferential direction of the fourth station 16 and contact the lower edge of the fixed die table 11 located at the first station 13 to form a seal for the fourth station 16. Since the bottom of the fixed die table 11 is in a sealed state, when the sealing end skirt and the fixed die table 11 located at the first station 13 are sealed with each other, the top of the fourth station 16 is sealed, and at the same time, the side wall of the pit and the retaining wall seal the circumference of the fourth station 16, so that the fourth station 16 is formed into an independent and closed curing room, which effectively reduces heat loss and saves maintenance costs.

[0045] In another optional embodiment of the present application, one side of the sealing skirt plate 8 is hinged to the inner wall of the pit, and the other side is driven by the gas rod 10 to abut against the lower edge of the fixed mold platform 11 located at the first station 13.

[0046] One end of the gas rod 10 is hinged to the inner wall of the pit, and the other end is connected to the non-hinged side of the sealing skirt plate 8. After the fixed mold platform 11 is placed on the first work station 13, the sealing skirt plate 8 is driven to rotate upward and abut against the lower edge of the fixed mold plate to achieve sealing.

[0047] In this embodiment, there are four sealing skirt plates 8, which respectively correspond to the inner walls of the pit around the fourth workstation 16 (one side of which is a retaining wall). A sealing strip can be set on the upper edge of the non-hinged end of the sealing skirt plate 8, and the fixed mold platform 11 is squeezed and maintained by the driving sealing difference of the gas rod 10, so as to improve the sealing effect by the sealing strip.

[0048] Correspondingly, when the fixed mold platform 11 located at the fourth station 16 moves upward to the first station 13, the first roller group 4 retracts, and the sealing skirt plate 8 is driven by the air rod 10 to fit the inner wall of the pit, providing a channel for the fixed mold platform 11 to move upward to the first station 13.

[0049] In another optional embodiment of the present application, the first roller set 4 and the second roller set 5 are in the same horizontal plane and are distributed in the same direction, so that the fixed die table 11 located at the first station 13 can be driven by an external force to move toward the second station 14. The fixed die table 11 located at the first station 13 can be moved to the second station 14 by human power, hydraulic cylinder drive, motor drive, etc.

[0050] In this embodiment, the first roller group 4 includes a plurality of horizontal cylinders respectively arranged at the two ends of the first station 13, the piston ends of the horizontal cylinders are horizontally extended to the inner wall of the pit, and the piston ends are provided with roller sleeves to form rollers;

[0051] Correspondingly, the second roller group 5 includes a plurality of horizontal cylinders respectively arranged at the two ends of the second station 14, the piston ends of the horizontal cylinders are horizontally extended and retracted on the inner wall of the pit, and roller sleeves are arranged at the piston ends to form rollers.

[0052] The horizontal oil cylinder is embedded in the inner wall of the pit and extends out when the fixed mold platform 11 needs to be supported. The piston end of the horizontal oil cylinder has a roller sleeve, which can move the fixed mold platform 11 through the roller sleeve to reduce friction. The horizontal cylinders of the first roller group 4 and the second roller group 5 are distributed in the same direction, which can enable the fixed mold platform 11 to move freely between the first station 13 and the second station 14.

[0053] In another optional embodiment of the present application, the third roller group 6 includes multiple fixed rollers; the fourth roller group 7 includes multiple fixed rollers, and the fourth roller group 7 and the third roller group 6 are in the same horizontal plane, so that the fixed mold table 11 located at the third workstation 15 can move to the fourth workstation 16 under external force.

[0054] The fixed rollers may be conventional fixed rollers arranged horizontally.

[0055] In this embodiment, the upper surface of the retaining wall is not higher than the upper surfaces of the first roller group 4 and the second roller group 5 , thereby ensuring that the fixed mold platform 11 can move between the first station 13 and the second station 14 .

[0056] A folding door 3 is provided in the middle of the retaining wall, and a driving motor is provided to drive the folding door 3 to open and close (the folding door 3 may also be a sliding door, a rolling door, etc.), so that the fixed mold platform 11 located at the third station 15 can move to the fourth station 16. The folding door 3 forms a moving channel for the fixed mold platform 11. After the fixed mold platform 11 moves from the third station 15 to the fourth station 16, the folding door 3 is closed to achieve sealing of the fourth station 16.

[0057] In another optional embodiment of the present application, the first lifter 12 is a plurality of longitudinal cylinders distributed circumferentially about the third station 15, and the piston end of the longitudinal cylinder can move longitudinally back and forth between the third station 15 and the second station 14; the stability of the fixed mold platform 11 during the movement is ensured by the plurality of longitudinal cylinders, wherein the longitudinal cylinders pass through the gaps between the rollers of the third roller group 6.

[0058] The second lifter 1 is a plurality of longitudinal cylinders distributed circumferentially about the fourth station 16, and the piston end of the longitudinal cylinder can longitudinally reciprocate between the fourth station 16 and the first station 13. The stability of the fixed die table 11 during the movement is ensured by the plurality of longitudinal cylinders, wherein the longitudinal cylinders pass through the gaps between the rollers of the fourth roller group 7.

[0059] In this embodiment, there are four longitudinal cylinders in the first lifter 12, and the four longitudinal cylinders correspond to the four corners of the fixed mold platform 11. There are four longitudinal cylinders in the second lifter 1, and the four longitudinal cylinders correspond to the four corners of the fixed mold platform 11.

[0060] In another optional embodiment of the present application, the side wall of the pit corresponding to the fourth station 16 is provided with an air hole 2, and the air hole 2 is connected to the steam supply device to supply steam to the fourth station 16. The pit is provided with an insulation layer corresponding to the fourth station 16. At the same time, since the insulation material is fixed in position and does not move, it can be made thicker and tightly sealed, which effectively reduces heat loss and saves maintenance costs during thermal maintenance.

[0061] In actual production operations, three fixed die tables 11 are arranged on the workbench for circulation, that is, in the initial state, the first station 13, the third station 15, and the fourth station 16 have fixed die tables 11. After the fixed die table 11 completes the operation at the first station 13, the sealing skirt plate 8 rotates downward and separates from the lower edge of the fixed die table 11, and the fixed die table 11 is pushed to the second station 14 by a driving device (which can be a horizontally arranged oil cylinder) or manpower, and the fixed die table 11 is transported to the second station 14 for temporary storage. At this time, the first station 13 is vacant, and the first roller group 4 is retracted to the inner wall of the pit by a hydraulic device to form the fourth station 1 6 is a transportation channel from the fourth station 13 to the first station 13, and the fixed mold platform 11 that has been thermally cured in the fourth station 16 is lifted to the top of the first station 13 by the second lifter 1, and then the first roller group 4 extends out of the inner wall of the pit to support the fixed mold platform 11, so that the fixed mold platform 11 of the fourth station 16 is transferred to the first station 13; the first lifter 12 is retracted to the bottom of the pit, and the sealing skirt plate 8 upwardly resists the lower edge of the fixed mold platform 11 transferred to the first station 13 to form a seal above the fourth station 16, ensuring that heat will not dissipate through the top of the fourth station 16. At this time, the first station 13 can start normal process operations.

[0062] Open the folding door 3 between the third station 15 and the fourth station 16, move the fixed mold platform 11 located at the third station 15 to the fourth station 16 by manpower or a driving device (which can be a horizontally arranged cylinder), close the folding door 3 between the third station 15 and the fourth station 16, and the movement of the fixed mold platform 11 to the fourth station 16 is completed, and steam can be supplied for thermal maintenance.

[0063] Raise the first lifter 12 to support the fixed mold platform 11 at the second station 14 upward, retract the horizontal cylinder of the second roller group 5 into the inner wall of the pit, move the fixed mold platform 11 temporarily stored on the second station 14 downward to the third roller group 6 at the third station 15, and retract the first lifter 12 into the bottom of the pit, and one operation flow is completed. Wait for the operation at the first station 13 to be completed before the next flow can be realized. The whole process is combined with thermal maintenance to achieve a full cycle of 3 mold platforms within 1 day, and achieve a production of 3 mold platforms with the finished products of 2 mold platforms per day.

[0064] In some embodiments, position sensors 9 corresponding to the fixed mold stage 11 are disposed on the first workstation 13 , the second workstation 14 , the third workstation 15 and the fourth workstation 16 to ensure the accuracy of the position movement of the fixed mold stage 11 .

[0066] In some embodiments, the drives of each gas rod 10, horizontal cylinder, longitudinal cylinder, and driving device in the present application are all controlled by a control cabinet to achieve electrical automation and reduce the labor intensity of workers.

[0067] In summary, the present application provides a three-dimensional concrete prefabricated production and maintenance cycle operation table, with four stations distributed in a three-dimensional manner, which can greatly reduce the space required for concrete operations and release the productivity of the workshop to the maximum extent. The four stations circulate the fixed mold platform 11, and the assembly line operation greatly improves the production efficiency. The independent maintenance room can improve the maintenance effect. The maintenance cost is reduced, which can not only save energy, but also can perform thermal maintenance on some components that were originally not thermally maintained, speed up production efficiency, and greatly improve the overall production capacity, increasing the profit of the enterprise.
