Description

Technical Field

[0001] This invention relates to the field of PC laminate storage technology, and more particularly to a storage rack for PC laminate production. Background Technology

[0002] As a crucial component in modern industrialized construction, precast concrete (PC) slabs typically require short-term turnover and centralized storage within the factory after prefabrication, pending transportation to the construction site. This process necessitates that storage supports possess sufficient load-bearing capacity and stability to ensure the slabs do not deform or become damaged during storage. Furthermore, they must be convenient for retrieval and adaptable to slabs of varying sizes and specifications, thereby improving production efficiency, reducing labor costs, and optimizing storage space utilization.

[0003] In existing technologies, common PC laminate storage racks mostly adopt a fixed structure, typically including a rectangular base frame and two pairs of fixed vertical support frames on both sides. Several layers of horizontally extending brackets are welded or bolted to the support frames to support the two side edges of the laminate. After the laminate is transported by hoisting equipment, it is placed on these brackets layer by layer from top to bottom.

[0004] However, existing storage racks have significant structural design flaws: First, they hinder the storage of laminated panels. Because the side supports are fixed, horizontally extending structures, the edges of the laminated panels are prone to lateral interference with the upper or same-layer supports when being lowered. To avoid collisions, operators often have to use a complex method: first, hoist the laminated panels to the side of the support frame, then horizontally slide them into the narrow space between the two layers of supports. This lateral insertion method requires extremely high precision from the hoisting equipment, is difficult to operate, inefficient, and carries the risk of damaging the laminated panels or the support frame. Second, the fixed width of the supports results in poor adaptability. A storage rack of a specific size has a fixed distance between its two support frames, allowing it to store only laminated panels of a single width that matches the distance between its support arms. For products of different widths produced in a factory, multiple sizes of supports are required. This not only increases equipment procurement and warehousing management costs but also makes the planning of storage areas on the production floor cumbersome and space utilization inflexible. Therefore, further improvements are needed. To this end, we propose a storage rack for PC laminate production. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a storage bracket for PC laminate production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a storage bracket for PC laminate production, comprising a base plate, two sets of side frames are provided on both sides of the upper surface of the base plate, each set of side frames includes two uprights and several support assemblies, each support assembly includes a tray, a connecting rod is fixed on the upper surface of the tray near the two uprights, the other end of the connecting rod is hinged to a connecting seat, the two connecting seats are respectively fixedly connected to the two uprights, a pressing assembly is slidably provided on the surface of the two uprights and above each support assembly, a plurality of insert plates for installing uprights are fixed on both sides of the upper surface of the base plate, a slot for inserting the insert plate is opened at the bottom of the upright, a side hole is opened on the side of the slot, and a snap-fit ​​assembly for fixing the insert plate is connected inside the side hole.

[0007] Furthermore, a locking hole is provided in the middle of the insert plate, and the locking assembly includes an insert rod that is slidably connected inside the side hole. One end of the insert rod is located inside the slot and is locked into the locking hole. The other end of the insert rod is fixed with an end plate, and the end plate and the outer wall of the upright are fixedly connected with a tension spring.

[0008] Furthermore, a pull ring is fixedly connected to the end of the end plate away from the insertion rod.

[0009] Furthermore, a crossbar is fixedly connected between the two uprights of each side frame.

[0010] Furthermore, the clamping assembly includes a sliding sleeve that is slidably fitted onto the surface of the upright. A pressure plate is fixed to the bottom end of the side wall of the sliding sleeve. A screw hole is opened on the side of the pressure plate away from the sliding sleeve, and a compression bolt is threaded inside the screw hole. A knob is fixed to the top of the compression bolt.

[0011] Furthermore, the side wall of the sliding sleeve is provided with a screw hole, and a locking bolt is threaded inside the screw hole. One end of the locking bolt is located inside the sliding sleeve and is in contact with the surface of the upright, while the other end of the locking bolt is fixed with a knob.

[0012] The beneficial effects of this invention are: 1. This invention solves the operational problem of traditional supports requiring lateral insertion of composite slabs by improving the structural design of the support components. During storage, the operator starts from the bottom of the support and rotates each layer of support components sequentially to a horizontal supporting state. After each layer is leveled, a composite slab can be vertically and smoothly lowered from directly above the support onto the surface of the leveled support component. Since the support components that are not yet leveled are still in a retracted state, their positions completely avoid the path of the vertical lowering of the composite slab, thus eliminating any lateral obstruction. This layer-by-layer leveling and vertical lifting operation eliminates the need for complex lateral translation and alignment of the composite slabs, significantly reducing the difficulty and operational risks of hoisting and greatly improving the safety and efficiency of storage operations.

[0013] 2. By selectively fixing the side frames on both sides to the insert plates at different positions on the base plate surface, the present invention can store composite plates of different widths. This structural improvement allows a single bracket to be quickly adjusted to adapt to products of various width specifications, effectively reducing the types and quantities of brackets required by the factory, optimizing the utilization of storage space, and reducing equipment purchase and management costs.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-4As shown, a storage rack for PC laminate production is disclosed, comprising a base plate 1. Two sets of side frames 2 are provided on both sides of the upper surface of the base plate 1. Each set of side frames 2 includes two uprights 3 and several support components 4. Each support component 4 includes a tray 41. A connecting rod 42 is fixed on the upper surface of the tray 41 near the two uprights 3. A connecting seat 43 is hinged to the other end of the connecting rod 42. The two connecting seats 43 are fixedly connected to the two uprights 3 respectively. A pressing component 5 is slidably provided on the surface of the two uprights 3 and above each support component 4. Multiple insert plates 7 for installing the uprights 3 are fixed on both sides of the upper surface of the base plate 1. A slot 31 for inserting the insert plate 7 is opened at the bottom of the upright 3. A side hole 32 is opened on the side of the slot 31. A snap-fit ​​component 8 for fixing the insert plate 7 is connected inside the side hole 32.

[0019] The insert plate 7 has a locking hole 71 in the middle. The locking assembly 8 includes an insert rod 81 that is slidably connected inside the side hole 32. One end of the insert rod 81 is located inside the slot 31 and is locked into the locking hole 71. The other end of the insert rod 81 is fixed with an end plate 82, and the end plate 82 and the outer wall of the upright 3 are fixedly connected with a tension spring 83.

[0020] When installing the side frame 2 on both sides of the base plate 1, first pull the end plate 82 at the bottom of the two uprights 3 so that the insertion rod 81 is removed from the slot 31. Then insert the bottom of the two uprights 3 into the surface of the corresponding insertion plate 7. Then release the end plate 82, and the tension spring 83 pulls the end plate 82 so that the insertion rod 81 is inserted into the locking hole 71, thereby realizing the fixed connection between the side frame 2 and the corresponding insertion plate 7.

[0021] A pull ring is fixedly connected to the end of the end plate 82 away from the insertion rod 81. When disassembling the side frame 2, it is more convenient to pull the end plate 82 via the pull ring. The end plate 82 causes the insertion rod 81 to separate from the locking hole 71, allowing the upright rod 3 to be removed from the surface of the insertion plate 7. Following this method, the side frames 2 can be fixed to the surfaces of the insertion plates 7 at different positions according to the required width of the stacked plate 9, thus adjusting the distance between the two side frames 2.

[0022] A crossbar 6 is fixedly connected between the two uprights 3 of each side frame 2. The crossbar 6 increases the stability between the two uprights 3.

[0023] The clamping assembly 5 includes a sliding sleeve 51 that is slidably sleeved on the surface of the upright 3. A pressure plate 52 is fixed at the bottom of the side wall of the sliding sleeve 51. A screw hole is opened on the side of the pressure plate 52 away from the sliding sleeve 51, and a pressing bolt 53 is threaded inside the screw hole. A knob is fixed on the top of the pressing bolt 53.

[0024] The sliding sleeve 51 has a screw hole on its side wall, and a locking bolt 54 is threaded inside the screw hole. One end of the locking bolt 54 is located inside the sliding sleeve 51 and is in contact with the surface of the upright 3. A knob is fixed to the other end of the locking bolt 54.

[0025] When placing the composite plate 9, first rotate the two support plates 41 at the same height on the two side frames 2 so that the support plates 41 are rotated to a horizontal position and the side of the support plate 41 abuts against the surface of the upright 3. Then, the composite plate 9 is hoisted from above and placed on the surface of the support plate 41 using hoisting equipment. Next, rotate the sliding sleeve 51 and move the sliding sleeve 51 downward so that the pressure plate 52 is above the composite plate 9. Then, tighten the locking bolt 54 to lock and fix the sliding sleeve 51. Finally, tighten the pressing bolt 53 to press and fix the composite plate 9. The composite plates 9 are stacked sequentially from bottom to top in this manner.

[0026] Working principle: When in use, first determine the installation position of the two side frames 2 on the base plate 1 according to the width of the stacked plate 9 to be stored. Pull the end plate 82 with the pull ring to make the insertion rod 81 exit from the slot 31. Align the slots 31 at the bottom of the two uprights 3 and place them on the corresponding insertion plates 7. After releasing the end plate 82, under the pulling force of the tension spring 83, the insertion rod 81 automatically snaps into the locking hole 71 of the insertion plate 7, thereby realizing a stable connection between the side frame 2 and the base plate 1 and completing the adjustment of the support width.

[0027] When storing the composite plate 9, starting from the bottom of the support, rotate the trays 41 on the two side frames 2 on the same layer so that they rotate around the hinge point of the connecting seat 43 to a horizontal state. At this time, the side of the tray 41 abuts against the upright 3 to form a stable supporting plane. Then, use hoisting equipment to vertically hoist the composite plate 9 from directly above the support and place it stably on the surface of the flattened tray 41.

[0028] Next, rotate and slide the sliding sleeve 51 above the layer downwards, causing the pressure plate 52 to move above the composite plate 9. Tighten the locking bolt 54 to fix the position of the sliding sleeve 51, and then tighten the pressing bolt 53 to press its bottom end against the upper surface of the composite plate 9, thereby achieving clamping and fixing of the composite plate 9.

[0029] Subsequently, following the steps of "rotating the pallet 41 to a horizontal position, hoisting the composite plate 9, sliding and locking the sliding sleeve 51, and tightening the clamping bolt 53" from bottom to top, all composite plates 9 can be stored layer by layer. The entire process only requires vertical hoisting and has no lateral obstruction. When it is necessary to disassemble or change the specifications, reverse the operation of the clamping bolt 53 and the locking bolt 54, and rotate the pallet 41 back to a non-horizontal position to release the fixation of the composite plate 9; by pulling the end plate 82 with the pull ring to separate the insertion rod 81 from the locking hole 71, the side frame 2 can be removed from the insertion plate 7 as a whole for width adjustment or removal of the bracket.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
