Description

Technical Field

[0001] This invention relates to the field of small prefabricated component production, and more specifically, to an automated production platform for small prefabricated components. Background Technology

[0002] Currently, small precast components (such as paving bricks and guardrails) are typically produced by casting using molds. Common small precast components include concrete small precast components. When producing concrete small precast components, the molds required for their production are first placed (usually on a workbench), and then concrete is poured into the molds sequentially. After the concrete in the molds is poured, the molds are moved sequentially to another workstation. Because the small precast component molds need to be neatly arranged during casting, and because they need to be moved after casting, the production efficiency of small precast components is relatively low. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0004] A small-scale automated production platform for precast components includes a mounting platform with legs on its lower end face and a hopper on its lower end face. A rotatable rotating frame is mounted on the mounting platform, and at least two material-holding racks are mounted on the rotating frame. The at least two material-holding racks are circumferentially distributed along the rotation axis of the rotating frame. The rotating frame is used to rotate the material-holding racks to a position below the hopper. The material-holding racks are also equipped with a unloading mechanism, which is used to lower the mold after the concrete in the mold has been poured.

[0005] By setting at least two material racks, the present invention can realize the production of small prefabricated components in a relatively continuous manner, thereby improving the production efficiency of small prefabricated components.

[0006] Preferably, the rotating frame includes an annular plate and a rotating shaft disposed at the center of the annular plate, and a connecting post for connecting the annular plate and the rotating shaft is provided between the annular plate and the rotating shaft.

[0007] In this invention, the rotating frame structure allows for relatively convenient driving of the rotating frame.

[0008] Preferably, the upper end of the rotating shaft extends out of the mounting platform, and the end of the rotating shaft extending out of the mounting platform is provided with a driven gear. The upper end face of the mounting platform is provided with a reduction gearbox, and the output shaft of the reduction gearbox is provided with a driving gear that meshes with the driven gear. The reduction gearbox is also provided with a reduction gearbox motor for connecting to the input shaft of the reduction gearbox.

[0009] In this invention, the arrangement of the driven gear, the driving gear, the reduction gearbox, and the reduction gearbox motor allows the operator to control the reduction gearbox motor to rotate the rotating frame, thus facilitating the operator's control of the rotating frame's rotation.

[0010] Preferably, the material holding rack includes four connecting plates connected end to end. Two of the four connecting plates have mounting plates on their inner sidewalls. The end face of the mounting plate away from the connecting plates has a slidable clamping plate along the height direction of the mounting plate. The clamping plate has multiple strip-shaped through holes, all arranged along the height direction of the clamping plate and evenly distributed along the length direction of the clamping plate. The unloading mechanism includes multiple mounting boxes located at the strip-shaped through holes on the clamping plates. Each mounting box contains a slidable support rod. The end of the support rod near the strip-shaped through hole has a first inclined surface. The mounting plate is used to push the end of the support rod out of the strip-shaped through hole. The bottom end of the mounting plate has a mounting plate through hole opposite to the strip-shaped through hole. The mounting box has an elastic mechanism for pushing the end of the support rod into the mounting plate through hole when the support rod moves downwards to the mounting plate through hole.

[0011] In this invention, the material holding rack structure provides an installation position for the mounting plate.

[0012] Preferably, the bottom end of the mounting plate is provided with a lower support bar located between the mounting plate and the clamping plate, and the upper end of the clamping plate is provided with an upper support bar located between the mounting plate and the clamping plate. The lower support bar is provided with a threaded rod, and a first spring for supporting the upper support bar is sleeved on the threaded rod. The upper support bar is provided with an upper support bar through hole that is clearance-fitted with the threaded rod. The end of the threaded rod extends out of the upper support bar through hole, and a nut is provided on the end of the threaded rod that extends out of the upper support bar through hole.

[0013] In this invention, the upper support bar, lower support bar, threaded rod and first spring are arranged to enable the small precast component mold to move downward stably, and at the same time the clamping plate can be reset.

[0014] Preferably, the mounting box includes a cover plate and a sealing cover connected to the cover plate. The cover plate and the sealing cover are respectively provided with through holes on the cover plate and through holes on the sealing cover that cooperate with the two ends of the support rod. The elastic mechanism includes a first guide post disposed on the cover plate. The end of the support rod located in the mounting box is provided with a support rod protrusion. The support rod protrusion is provided with a protrusion through hole that is clearance-fitted with the first guide post. The end of the first guide post extends out of the protrusion through hole. A second spring is also sleeved on the first guide post between the cover plate and the support rod protrusion.

[0015] In this invention, the elastic mechanism, in conjunction with the small precast component mold, allows the end of the support rod to retract into the strip-shaped through hole relatively quickly, thereby improving the stability of the automated production platform for small precast components during use.

[0016] Preferably, the lower end of the cover plate has a lower through hole, and the mounting box has a slidable reset rod with a second inclined surface at the end near the through hole. The cover plate also has a support block located at the lower end of the lower through hole, and the support block has two second guide posts perpendicular to the support block. The mounting box has a connecting block that can move along the height direction of the clamping plate, and the connecting block has a connecting block through hole that fits with the second guide posts. The lower end of the connecting block has a third inclined surface, which is used to press the end of the reset rod when the connecting block moves downward, so that the reset rod moves toward the end of the through hole. The lower end face of the support rod has a wedge, which is used to press the connecting block when the end of the support rod moves toward the mounting plate, so that the connecting block moves downward.

[0017] In this invention, the reset rod and connecting block can support the falling small precast component mold, thereby buffering the small precast component mold and automatically resetting the clamping plate, avoiding the need for workers to manually reset the clamping plate.

[0018] Preferably, the connecting block expands outward from the outer wall of the mounting box to form an expansion section.

[0019] In this invention, the expansion portion prevents the reset rod from sliding out of the mounting box, thereby improving the stability of the automated production platform for small prefabricated components during use.

[0020] Preferably, the end face of the clamp plate adjacent to the mounting plate is provided with toothed grooves at both ends of the strip-shaped through hole, and the end face of the cover plate adjacent to the clamp plate is provided with locking teeth that cooperate with the toothed grooves. The clamp plate is provided with a fixing mechanism for fixing the mounting box. The fixing mechanism includes L-shaped plates provided on the clamp plate and located at both ends of the strip. The L-shaped plates are provided with screw holes, and bolts for abutting the cover plate against the clamp plate are provided in the screw holes.

[0021] In this invention, the design of the toothed groove and the locking teeth not only prevents the mounting box from sliding on the clamping plate, but also allows the mounting box to be adjusted to accommodate small precast component molds with different load-bearing capacities, thereby significantly improving the applicability of the automated production platform for small precast components.

[0022] Preferably, a first connecting frame is provided on the end face of the connecting plate adjacent to the mounting plate, and a second connecting frame is provided on the end face of the mounting plate adjacent to the connecting plate. A connecting rod for connecting the mounting plate and the connecting plate is provided between the mounting plate and the connecting plate. The two ends of the connecting rod extend into the first connecting frame and the second connecting frame respectively, and the two ends of the connecting rod are bolted to the first connecting frame and the second connecting frame respectively.

[0023] In this invention, the arrangement of the first connecting frame, the second connecting frame, and the connecting rod allows workers to select a suitable length of connecting rod to connect with the mounting plate and the connecting plate according to the specifications of the small precast component mold, making the material rack more suitable for small precast component molds of different specifications.

The two ends of the connecting rod 460 are bolted to the first connecting frame 440 and the second connecting frame 450 respectively.

[0040] A clamping plate 430, which can slide along the height direction of the mounting plate 420, is provided on the end face of the mounting plate 420 away from the connecting plate 410. Figure 8As shown, in this embodiment, in order to enable the clamping plate 430 to slide on the mounting plate 420, a lower support bar 810 is provided at the bottom end of the mounting plate 420 between the mounting plate 420 and the clamping plate 430, and an upper support bar 820 is provided at the upper end of the clamping plate 430 between the mounting plate 420 and the clamping plate 430. A threaded rod 830 is provided on the lower support bar 810, and a first spring 840 for supporting the upper support bar 820 is sleeved on the threaded rod 830. An upper support bar through hole 860 is provided on the upper support bar 820 with clearance fit with the threaded rod 830, and the end of the threaded rod 830 extends out of the upper support bar through hole 860. A nut 850 is provided on the end of the threaded rod 830 extending out of the upper support bar through hole 860.

[0041] Combination Figure 5-7 As shown, the clamping plate 430 is provided with a plurality of strip-shaped through holes 610, which are all arranged along the height direction of the clamping plate 430 and are evenly distributed along the length direction of the clamping plate 430. The unloading mechanism includes a plurality of mounting boxes 620 provided at the strip-shaped through holes 610 on the clamping plate 430. The mounting box 620 is provided with a slidable support rod 710. The end of the support rod 710 near the strip-shaped through hole 610 is provided with a first inclined surface 720. The mounting plate 420 is used to push the end of the support rod 710 out of the strip-shaped through hole 610. The bottom end of the mounting plate 420 is provided with a mounting plate through hole 630 opposite to the strip-shaped through hole 610. The mounting box 620 is provided with an elastic mechanism for pushing the end of the support rod 710 into the mounting plate through hole 630 when the support rod 710 moves downward to the mounting plate through hole 630. The mounting box 620 includes a cover plate 730 and a sealing cover 740 connected to the cover plate 730. The cover plate 730 and the sealing cover 740 are respectively provided with through holes 750 on the cover plate and through holes 7190 on the sealing cover, which cooperate with the two ends of the support rod 710. The elastic mechanism includes a first guide post 760 provided on the cover plate 730. The end of the support rod 710 located in the mounting box 620 is provided with a support rod protrusion 770. The support rod protrusion 770 is provided with a protrusion through hole 780 that is clearance-fitted with the first guide post 760. The end of the first guide post 760 extends out of the protrusion through hole 780. A second spring 790 is also sleeved on the first guide post 760, located between the cover plate 730 and the support rod protrusion 770. The clamping plate 430 has a toothed groove 870 on the end face adjacent to the mounting plate 420, located at both ends of the strip-shaped through hole 610. The cover plate 730 has a locking tooth 7170 on the end face adjacent to the clamping plate 430, which cooperates with the toothed groove 870. The clamping plate 430 has a fixing mechanism for fixing the mounting box 620. The fixing mechanism includes an L-shaped plate 880 set on the clamping plate 430 and located at both ends of the strip. The L-shaped plate 880 has a screw hole 890, and the screw hole 890 has a bolt 7180 for abutting the cover plate 730 against the clamping plate 430.

[0042] Combination Figure 9 as well as Figure 10 As shown, the lower end of the cover plate 730 is provided with a lower through hole 7100, and the mounting box 620 is provided with a slidable reset rod 7110. The end of the reset rod 7110 near the strip-shaped through hole 610 is provided with a second inclined surface 7120. The cover plate 730 is also provided with a support block 7130 located at the lower end of the lower through hole 7100. The support block 7130 is provided with two second guide posts 7140 arranged perpendicular to the support block 7130. The mounting box 620 is provided with a connecting block 7150 that can move along the height direction of the clamping plate 430. The connecting block 7150 expands outward from the outer wall of the mounting box 620 to form an expansion part 7160. The connecting block 7150 is provided with a connecting block through hole 910 that is clearance-fitted with the second guide post 7140; the lower end of the connecting block 7150 is provided with a third inclined surface 920, which is used to press the end of the reset rod 7110 when the connecting block 7150 moves downward, so that the reset rod 7110 moves toward the end of the strip-shaped through hole 610; the lower end face of the support rod 710 is provided with a wedge 1010, which is used to press the connecting block 7150 when the end of the support rod 710 moves toward the end of the mounting plate 420, so that the connecting block 7150 moves downward.

[0043] In use, the small precast component mold required for making small precast components is first placed between the two clamping plates 430 on the material rack 150. The small precast component mold is supported by the first inclined surface 720 on the support rod 710 in the mounting box 620 on the clamping plate 430. Then, the gearbox motor 330 is started to rotate one of the material racks 150 of the rotating frame 140 to the bottom of the hopper 130. In this example, a baffle 470 for connecting the two mounting plates 420 on the material rack 150 is also provided. The baffle 470 can prevent the small precast component mold from falling between the two clamping plates 430, thereby improving the stability of the small precast component automated production platform during use. When the small precast component mold moves to the bottom of the hopper 130, the hopper 130's filling port is opened to add concrete material to the small precast component mold, increasing the mold's mass. As the mass of the small precast component mold increases, the clamping plate 430 moves downward with the mold and compresses the first spring 840. When the support rod 710 in the mounting box 620 on the clamping plate 430 moves to the mounting plate through hole 630 on the mounting plate 420, the small precast component mold compresses the first inclined surface 720 and the second spring 790, causing the end of the support rod 710 to retract into the strip through hole 610, thus causing the small precast component mold to fall automatically (at this time, the hopper 130's outlet is closed). In this embodiment, a conveyor belt is provided below the hopper 130. After the small precast component mold falls onto the conveyor belt, the worker can remove it from the conveyor belt.

[0044] The automated production platform for small precast components in this embodiment is equipped with at least two material racks 150. When the mold for a small precast component on one of the material racks 150 rotates to the bottom of the hopper 130, the operator can replenish the mold for a small precast component on the other material racks 150. This allows for more continuous production of small precast components and thus improves the production efficiency of small precast components.

[0045] In this embodiment, the rotating frame 140 structure allows the operator to drive the rotating shaft 220 to rotate during operation, thus facilitating the driving of the rotating frame 140. The driven gear 240, driving gear 320, reduction gearbox 310, and reduction gearbox motor 330 enable the operator to control the reduction gearbox motor 330 to rotate the rotating frame 140, thereby simplifying the operation of the rotating frame 140.

[0046] In this embodiment, the structure of the material holding rack 150 allows for the installation of mounting plates 420 on two connecting plates 410, and the installation of clamping plates 430 on the mounting plates 420 to support small precast component molds. The arrangement of the first connecting frame 440, the second connecting frame 450, and the connecting rod 460 allows operators to select a suitable length of connecting rod 460 to connect with the mounting plates 420 and connecting plates 410 according to the specifications of the small precast component mold. This adjusts the distance between the clamping plates 430 on the two mounting plates 420 of the material holding rack 150, making the material holding rack 150 more suitable for small precast component molds of different specifications, thus significantly improving its applicability. By configuring the upper support bar 820, lower support bar 810, threaded rod 830, and first spring 840, when no material is added to the small precast component mold, the first spring 840 can move the clamping plate 430 against the upper part of the mounting plate 420. When the mass of the small precast component mold increases due to the addition of material, the first spring 840 will move downward, thereby causing the small precast component mold and the clamping plate 430 to move downward. In this embodiment, the first spring 840 enables the small precast component mold to move downward stably and also enables the clamping plate 430 to be reset. It should be noted that during reset, the operator needs to push the end of the support rod 710 out of the through hole 630 of the mounting plate.

[0047] In this embodiment, the support rod 710 on the mounting box 620 in the unloading mechanism allows the end of the support rod 710 to retract into the slotted through-hole 610 when it is at the through-hole 630 of the movable mounting plate. This is achieved by the small precast component mold pressing against the first inclined surface 720 and the action of the second spring 790. This allows the small precast component mold to fall downwards and automatically detach from the material rack 150, thus achieving relatively quick detachment of the small precast component mold. Furthermore, the elastic mechanism allows it to work in conjunction with the small precast component mold when the end of the support rod 710 is at the through-hole 630 of the movable mounting plate, enabling the end of the support rod 710 to retract into the slotted through-hole 610 relatively quickly. This significantly improves the stability of the automated small precast component production platform during use.

[0048] In this embodiment, the L-shaped plate 880, screw holes 890 and bolts 7180 are provided so that when the mounting box 620 is installed on the clamping plate 430, the cover plate 730 on the mounting box 620 can be abutted against the clamping plate 430 by the bolts 7180 to fix the mounting box 620, thereby making it easier to install the cover plate. The design of the grooves 870 and the locking teeth 7170 not only improves the fixing effect of the mounting box 620 and prevents it from sliding on the clamping plate 430, but also allows the locking teeth 7170 on the cover plate 730 to engage with different grooves 870 during the installation of the mounting box 620. This adjusts the distance between the support rod 710 and the through hole 630 of the mounting plate, and also allows the mounting box 620 to be adjusted to accommodate different load-bearing small precast component molds when changing them. This significantly improves the applicability of the automated production platform for small precast components.

[0049] In this embodiment, by setting the reset rod 7110 and the connecting block 7150, the end of the support rod 710 can be retracted into the strip-shaped through hole 610. The wedge block 1010 on the support rod 710 presses the connecting block 7150 to make the connecting block 7150 move downward. The third inclined surface 920 on the connecting block 7150 presses the reset rod 7110 to make the end of the reset rod 7110 extend out of the strip-shaped through hole 610 to support the falling small precast component mold, thereby achieving buffering for the small precast component mold. At the same time, when the small precast component mold... When the component lands on the reset rod 7110, the pressure from the small precast component mold squeezes the reset rod 7110, causing the end of the reset rod 7110 to press against the connecting block 7150 and move upward. Through the cooperation between the connecting block 7150 and the wedge block 1010, the support rod 710 overcomes the elastic force of the second spring 790 and moves out of the through hole 630 of the mounting plate. At this time, the clamping plate 430 moves back to the upper end of the mounting plate 420 under the action of the first spring 840, thereby realizing the automatic reset of the clamping plate 430 and avoiding manual reset by the operator. The expansion part 7160 prevents the reset rod 7110 from sliding out of the mounting box 620, thus improving the stability of the small precast component automated production platform during use.

[0050] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
