[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0034] As Figures 1-13 shown, the prefabricated component yard for assembled construction includes a base plate 1 and a stacking platform 11 provided on the base plate 1 for stacking precast slab components; it also includes lifting frames provided on the base plate 1 and located on both sides of the stacking platform 11, and a positioning mechanism that can move up and down is provided on the lifting frames for positioning and straightening the four sides of the precast slab; a feedback mechanism is also provided on the positioning mechanism, so that when the precast slab is lowered, it can drive the positioning mechanism to perform the positioning and straightening action. During the stacking operation, the construction workers only need to cooperate to place the sleepers, and then the crane automatically hoists and transports the precast slab to the stacking platform 11. When it is about to land, it will first press on the feedback mechanism, and the feedback mechanism transmits the gravity of its lowering to the positioning mechanism, enabling it to assist in pushing against the four sides of the suspended precast slab, thereby straightening it. After it is completely straightened, the feedback mechanism withdraws from the bottom of the precast slab, and the lifting frame lifts the entire positioning mechanism up one level, thereby preparing for the stacking of the next precast slab. During the whole process, the construction workers only need to place the sleepers, thus avoiding the inaccuracy and potential risks brought by manual straightening.
[0035] In one embodiment, the lifting frame includes a drive control box base 2 provided on the base plate 1, a mounting frame 21 provided on the drive control box base 2, a threaded lead screw 22 rotatably arranged between the drive control box base 2 and the mounting frame 21 and driven by the power of the drive control box base 2, and a limit slide bar 23 fixedly arranged between the drive control box base 2 and the mounting frame 21. A gear set is arranged inside the drive control box base 2 to amplify the output torque of the threaded lead screw 22, and the internal structure can be self-locked, thereby ensuring the lifting stability of the threaded lead screw 22 for the positioning mechanism.
[0036] In one embodiment, the positioning mechanism includes a cross suspension 3 sleeved on the threaded lead screw 22 and the limit slide bar 23 and capable of performing reciprocating up and down movement driven by the threaded lead screw 22, a lateral guiding component that is limited and movable along the orthogonal direction of the cross suspension 3, and a longitudinal guiding component arranged on the lateral guiding component and perpendicular to its movement direction; the lateral guiding component includes limit side plates 4 arranged on both sides of the cross suspension 3 and transverse push clamping plates 41 arranged on the limit side plates 4, wherein sliding card slots 42 for limit clamping connection with the limit side plates 4 are provided on both sides of the transverse push clamping plates 41; movable grooves 5 are provided on both sides of the transverse push clamping plates 41, and the longitudinal guiding component includes longitudinal push clamping plates 51 that are limited and slide in the movable grooves 5 and first return springs 52 arranged between the longitudinal push clamping plates 51 and the inner walls of the movable grooves 5; first limit sliding grooves 53 are provided on the upper and lower side walls of the movable grooves 5, and first limit sliding blocks 54 that are limited and slide in the first limit sliding grooves 53 are arranged on both sides of the longitudinal push clamping plates 51. The cross suspension 3 serves as a horizontal stable structure for the lateral guiding component and the longitudinal guiding component, ensuring that the two can only perform guiding actions in the horizontal direction. When the transverse push clamping plates 41 slide along the limit side plates 4, they perform abutting and guiding from the left and right sides of the precast slab, and the longitudinal push clamping plates 51 at their upper ends move relatively from both sides of the transverse push clamping plates 41, thereby performing abutting and guiding on the edge positions on the front and rear sides of the precast slab, and further accurately limiting the landing point of the precast slab to be centered.
[0037] In one embodiment, the feedback mechanism includes a transmission component disposed between the lateral guiding component and the longitudinal guiding component, and a trigger component disposed on the transmission component for supporting the precast slab and feeding back the gravity of the precast slab to the transmission component. First wedge surfaces 6 are provided on both sides of the transverse suspension 3, and a second wedge surface 61 matching the first wedge surface 6 is provided at the rear side of the longitudinal pushing clamping plate 51. The transmission component includes a connecting rod 62 with one end hinged to the longitudinal pushing clamping plate 51, and a pivot 63 rotatably disposed at one end of the first wedge surface 6 away from the longitudinal pushing clamping plate 51 and forming a hinge between the two sets of first wedge surfaces 6. A second limiting sliding groove 64 is formed in the transverse pushing clamping plate 41. The feedback component includes a limiting frame 65 rotatably connected to the pivot 63 and clamped in the second limiting sliding groove 64 for vertical limiting sliding, a transverse cantilever 66 disposed on the limiting frame 65, and a first steel wheel 67 rotatably disposed at the end of the transverse cantilever 66. When the precast slab is lowered, its bottom surface will press on the transverse cantilever 66, thereby driving the limiting frame 65 to move downward. The limiting frame 65 drives the hinged ends of the connecting rods 62 to move downward through the pivot 63. Since the height position of the transverse pushing clamping plate 41 is limited by the transverse suspension 3, the mutually remote ends of the connecting rods 62 pull the longitudinal pushing clamping plate 51 to slide towards the opposite side, thereby realizing the relative clamping action in the front and rear directions. During the sliding process of the longitudinal pushing clamping plate 51, the second wedge surface 61 at its rear side will slide relatively and out of alignment with the first wedge surface 6. Since the position of the transverse suspension 3 is fixed, the longitudinal pushing clamping plate 51 drives the transverse pushing clamping plate 41 to slide under the reverse pushing action of the transverse suspension 3, thereby realizing the relative clamping action in the left and right directions. Thus, when the precast slab is lowered, it is positioned correctly by the pushing and clamping actions of the transverse pushing clamping plate 41 and the longitudinal pushing clamping plate 51 on its front, rear, left, and right sides simultaneously.
[0038] In one embodiment, the transverse cantilever 66 is vertically limited and slides within the limit frame 65, and a second return spring 68 is provided between the transverse cantilever 66 and the bottom side wall of the limit frame 65. The elastic force of the second return spring 68 is greater than the total elastic force of the first limit chutes 53 on the left and right sides. A third limit chute 7 is formed on the side wall of the limit frame 65. A limit sleeve 71 is arranged within the limit frame 65. Second limit sliders 72 that are clamped and move within the third limit chute 7 are provided on both sides of the limit sleeve 71. The transverse cantilever 66 is movably inserted through the limit sleeve 71. A rear limit plate 73 is further provided at one end of the transverse cantilever 66 away from the first steel wheel 67. A third return spring 74 is provided between the rear limit plate 73 and the limit sleeve 71. A wedge block 75 is arranged on the inner wall of the limit frame 65. A sliding sleeve ring 76 that is sleeved on the wedge block 75 and is adapted to it is provided on one side of the rear limit plate 73 away from the third return spring 74. A trigger switch 8 that is signal-connected to the drive control box seat 2 and is located below the limit sleeve 71 is further provided on the limit frame 65. The limit frames 65 are connected by a linkage arm 81. The linkage arm 81 enables the two limit frames 65 to move synchronously, ensuring high coordination of the feedback mechanisms on the left and right sides. When the precast slab is lowered and drives the horizontal push clamping plate 41 and the vertical push clamping plate 51 to perform centering on it from the front, back, left, and right by gravity, at this time it is in a clamped state. The precast slab continues to fall in the centered state. Since the horizontal push clamping plate 41 and the vertical push clamping plate 51 have clamped the side ends of the slab body, they cannot continue to move. At this time, the limit frame 65 cannot continue to move downward. Furthermore, the transverse cantilever 66 will drive the limit sleeve 71 to continue to slide downward within the limit frame 65. During the sliding process, the sliding sleeve ring 76 slides on the outer surface of the wedge block 75 and is thus pushed back by the wedge block 75, causing the transverse cantilever 66 to slide backward and contract until the first steel wheel 67 is separated from the precast slab. At this time, the lower surface of the wedge block 75 just presses on the trigger switch 8, thereby triggering the drive control box seat 2 to drive the threaded lead screw 22 to rotate, and then driving the transverse suspension 3 to move upward a certain distance. In this way, the transverse suspension 3 will move upward step by step according to the internal preset algorithm until it reaches the highest position limited for stacking. Pressing the trigger switch 8 again will trigger the threaded lead screw 22 to drive the transverse suspension 3 to reset to the lowest position. Thus, the positioning and stacking work of a single group of storage yards is completed.
[0039] In one embodiment, fixing plate frames 9 are further provided on the horizontal push clamping plate 41 and the vertical push clamping plate 51. A plurality of groups of second steel wheels 91 are rotatably arranged between the fixing plate frames 9. Through the arrangement of the second steel wheels 91, the friction force between the horizontal push clamping plate 41, the vertical push clamping plate 51 and the surface of the precast slab is further reduced, and the loss between structures is reduced.
[0040] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
