Description

Technical Field

[0001] This invention relates to the field of storage devices, and more particularly to a three-dimensional storage device using a composite PC component. Background Technology

[0002] Precast concrete components refer to concrete components that are prefabricated in a factory and then transported to the construction site for installation. Among them, composite slabs, as an important type of horizontal load-bearing PC component, are widely used in prefabricated buildings due to their advantages such as improved construction efficiency, savings in formwork, and shorter construction periods. During the production process of precast composite slabs, the concrete needs to undergo a certain period of curing after pouring to reach the design strength requirements. The storage method during the curing period has a significant impact on the quality of the component.

[0003] Currently, the mainstream and standardized storage methods in the industry mainly include three types: First, horizontal stacking storage, where composite slabs are stacked horizontally layer by layer, separated by spacers. This method is suitable for situations where the strength of the components gradually increases during the curing period and the site is flat and has sufficient load-bearing capacity. It is the most common storage form for composite slabs during the curing period, but it has high requirements for the site and the number of stacked layers is limited. The number of layers should not be too many during the curing period, otherwise cracks may occur due to localized stress concentration. It is also not suitable for high-precision, large-span, or irregularly shaped components, as the stacking pressure can easily affect the accuracy of the components. At the same time, the position and alignment of the spacers must be strictly controlled, as improper operation can easily lead to quality problems such as component detachment and misalignment. Second, single-layer flat storage, where composite slabs are stacked horizontally layer by layer, separated by spacers. The first method involves placing the composite slabs horizontally on the ground or on blocks. This method is suitable for composite slabs with extremely high requirements for flatness, large size (such as spans exceeding 6m), and complex embedded parts or reserved holes. It can minimize the deformation of components caused by stacking pressure. However, this method has extremely low space utilization, with each component occupying a large area. It is not suitable for batch storage, has high costs and low construction efficiency, and requires individual hoisting during batch transportation, making site management difficult. The second method involves storing the composite slabs on special brackets. These brackets are used to fix and support the composite slabs. This method is suitable for irregularly shaped composite slabs, those with short curing periods (within 7 days, when component strength is low), or those where the site is too small to be stacked horizontally. The special brackets can fix the components to prevent them from tipping over or deforming.

[0004] However, all three storage methods mentioned above are static planar storage methods, which share common problems such as low storage density, low site utilization, high manual intervention, and low transfer efficiency. With the continuous expansion of prefabricated building scale and the sustained increase in precast component production, traditional storage methods can no longer meet the demands of modern precast component production plants for efficient, intensive, and intelligent storage. Therefore, there is an urgent need to develop a new type of composite slab storage and curing device that can achieve three-dimensional, high-density storage while possessing automated transfer capabilities, in order to improve site utilization, reduce labor costs, increase production efficiency, and ensure the storage quality of composite slabs during the curing period. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a three-dimensional storage device for composite PC components, thus solving the above problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a three-dimensional storage device for composite PC components, comprising: a main frame structure, a horizontal transmission structure, and a vertical transmission structure; The main frame structure of the device includes horizontal supports and vertical supports. The horizontal supports and vertical supports are connected to each other to form a three-dimensional frame, which is used to support the overall structure of the device and ensure the overall rigidity of the device. The horizontal transmission structure is located at the bottom of the main frame structure of the device and includes a transmission roller, a motor, a support plate, a connecting gasket, a bearing, a transmission shaft, and a transmission belt. The transmission roller is mounted on the support plate through the bearing, and the transmission shaft is connected to the transmission roller through the connecting gasket. The motor drives the transmission shaft to rotate through the transmission belt, which is used to horizontally input the stacked plate into the main frame structure of the device. The vertical transmission structure includes a second motor, a transmission screw, a vertical conveying block, support feet, a limiting slide rail, a lower fixed frame, an upper fixed frame, and a threaded ring. The lower fixed frame and the upper fixed frame are respectively installed at the lower and upper parts of the vertical support. The transmission screw is rotatably connected between the lower fixed frame and the upper fixed frame. The second motor is installed on the upper fixed frame and connected to the transmission screw. The vertical conveying block is threadedly connected to the transmission screw through the threaded ring. The limiting slide rail is installed on the vertical support, and the vertical conveying block slides in cooperation with the limiting slide rail. The support feet are installed on the vertical conveying block and are used to support and vertically move the stacked plate.

[0007] Preferably, it also includes a stabilizing structure, which includes a stabilizing frame, a positioning ratchet, a linkage shaft, a stacked plate support, a fixing plate, a limiting spring, and a locking plate. The stabilizing frame is mounted on the vertical conveying block, the linkage shaft is mounted on the stabilizing frame via bearings, the positioning ratchet is fixedly mounted on the linkage shaft, the stacked plate support is fixedly connected to the linkage shaft, the fixing plate is mounted on the stabilizing frame, and the locking plate is connected to the fixing plate via a limiting spring. The locking plate engages with the tooth groove of the positioning ratchet to lock the tilt angle of the stacked plate support.

[0008] Preferably, the main frame structure of the device is provided with multiple horizontal storage spaces, and each storage space is provided with a set of vertical conveying blocks and support feet. The vertical transmission structure is driven by a motor to drive the transmission screw to rotate, thereby driving the vertical conveying blocks of each layer to rise and fall synchronously, realizing the vertical transfer of the stacked plate between the multiple storage spaces.

[0009] Preferably, the horizontal transmission structure has multiple sets of transmission rollers, which are arranged at equal intervals along the horizontal direction. Adjacent transmission rollers are linked by a transmission shaft and a transmission belt. The motor is located at one end of the horizontal transmission structure and drives all transmission rollers to rotate synchronously through the transmission belt.

[0010] Preferably, the composite plate support is located on the inner side of the outer end of the linkage shaft, the positioning ratchet is located between the two composite plate supports, and the linkage shaft is connected to the ratchet drive. The locking piece is kept engaged with the positioning ratchet under the action of the limiting spring. When the composite plate is placed on the composite plate support, the composite plate support rotates under force and triggers the automatic locking of the positioning ratchet and the locking piece.

[0011] Preferably, multiple vertical conveying blocks are provided, and the multiple vertical conveying blocks are arranged at equal intervals along the vertical direction on the same vertical support. Each vertical conveying block is threadedly connected to the transmission screw through an independent threaded ring, and the spacing between adjacent vertical conveying blocks matches the layer spacing of the main frame structure of the device.

[0012] Preferably, the limiting slide rail is located on the outside of the lower fixed frame and the upper fixed frame, and the vertical conveying block is provided with corresponding sliding grooves on both sides. The vertical conveying block slides with the limiting slide rail through the sliding grooves to limit the circumferential rotation of the vertical conveying block and guide it to move in the vertical direction.

[0013] Preferably, the upper surface of the support foot is provided with an anti-slip pad layer, which is made of rubber or polyurethane material to increase the friction with the bottom surface of the composite plate and prevent the composite plate from slipping during vertical movement.

[0014] Preferably, the end of the locking piece is provided with a wedge-shaped locking head that matches the tooth shape of the positioning ratchet. The inclination direction of the wedge-shaped locking head is opposite to the force rotation direction of the positioning ratchet, so that the composite plate support leg can only rotate in the supporting direction and cannot rotate in the opposite direction when under load.

[0015] Preferably, the horizontal and vertical supports of the main frame structure of the device are made of welded or bolted steel sections. The horizontal support is provided with reinforcing ribs, and the bottom of the vertical support is provided with anchor bolt connecting plates for fixing the device to a concrete foundation.

[0016] Beneficial effects This invention provides a three-dimensional storage device for composite PC components. Compared with the prior art, it has the following advantages: 1. In this invention, by setting up a vertical transmission structure, the composite slabs are stored independently layer by layer. Each layer of components is supported by a separate support leg, avoiding the stacking effect of upper layer components on lower layer components in the traditional stacking method. This fundamentally eliminates the quality hazard of cracks caused by localized stress concentration. At the same time, the horizontal transmission structure, together with the vertical conveying block, can accurately transport the composite slabs to the designated layer without relying on the alignment of pad blocks, significantly reducing the difficulty of operation and the risk of components falling off or misaligning. Moreover, the three-dimensional storage method greatly increases the storage capacity per unit area, and is suitable for storing composite slabs of various specifications, sizes and irregular shapes. It solves the limitation of component types on traditional horizontal stacking. In addition, during batch transfer, the composite slabs of the target layer can be directly lowered to the horizontal transmission structure for centralized transfer through the vertical conveying block, without the need for individual hoisting, which significantly improves construction efficiency. Under the same floor area conditions, it can achieve several times the storage capacity of single-layer flat storage, greatly saving site resources and reducing labor and material costs. It is also suitable for storing composite slabs of different strength stages and different specifications and sizes during the curing period, and has wide applicability and significant economic benefits. 2. In this invention, through the designed stable structure, when the laminated plate is placed on the laminated plate support, the support tends to rotate downwards under the action of gravity. This rotation is transmitted to the positioning ratchet via the linkage shaft. The tooth groove of the positioning ratchet and the locking plate are kept engaged under the action of the limiting spring, thereby achieving instant locking of the tilt angle of the laminated plate support. This effectively prevents the laminated plate from slipping or overturning due to the rotation of the support during placement or transportation. In addition, the wedge-shaped locking head at the end of the locking plate and the positioning... The ratchet teeth are matched, and the tilt direction of the wedge-shaped chuck is opposite to the force rotation direction of the positioning ratchet. This means that the composite plate support can only rotate in the supporting direction and not in the opposite direction when under load. As the weight of the composite plate increases, the composite plate support rotates tighter and tighter, and the engagement between the chuck and the positioning ratchet becomes more secure. This achieves a virtuous cycle where the heavier the composite plate, the tighter the clamping. This greatly enhances the device's adaptability to composite plates of different weights and specifications, and effectively solves the quality hazards of components easily falling out, misaligning, or tipping over in traditional storage methods.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

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.

[0020] Please see Figures 1-6 The present invention provides two technical solutions, specifically including the following embodiments: Example 1: A three-dimensional storage device for composite slab PC components includes: a main frame structure 1, a horizontal transmission structure 2, and a vertical transmission structure 3. The horizontal support 101 and the vertical support 102 of the main frame structure 1 are welded or bolted together from steel profiles. The horizontal support 101 is provided with a reinforcing rib plate, and the bottom of the vertical support 102 is provided with an anchor bolt connecting plate for fixing the device to a concrete foundation. The main frame structure 1 of the device includes a horizontal support 101 and a vertical support 102. The horizontal support 101 and the vertical support 102 are connected to each other to form a three-dimensional frame, which is used to support the overall structure of the device and ensure the overall rigidity of the device. The horizontal transmission structure 2 is located at the bottom of the main frame structure 1 of the device, and includes a transmission roller 201, a motor 202, a support plate 203, a connecting gasket 204, a bearing 205, a drive shaft 206, and a drive belt 207. The transmission roller 201 is mounted on the support plate 203 via the bearing 205. The drive shaft 206 is connected to the transmission roller 201 via the connecting gasket 204. The motor 202 drives the drive shaft 206 to rotate via the drive belt 207, which is used to horizontally input the stacked plate 4 into the main frame structure 1 of the device. The main frame structure 1 of the device has multiple layers of horizontal storage space, each layer of which... A set of vertical conveying blocks 303 and support feet 304 are set up accordingly. The vertical transmission structure 3 drives the transmission screw 302 to rotate through the motor 2 301, which drives the vertical conveying blocks 303 of each layer to rise and fall synchronously, realizing the vertical transfer of the stacked plate 4 between multiple storage spaces. The horizontal transmission structure 2 has multiple sets of transmission rollers 201, which are arranged at equal intervals in the horizontal direction. Adjacent transmission rollers 201 are linked by a transmission shaft 206 and a transmission belt 207. The motor 1 202 is set at one end of the horizontal transmission structure 2 and drives all transmission rollers 201 to rotate synchronously through the transmission belt 207. The vertical conveying structure 3 includes a second motor 301, a transmission screw 302, a vertical conveying block 303, a support foot 304, a limiting slide rail 305, a lower fixed frame 306, an upper fixed frame 307, and a threaded ring 308. The lower fixed frame 306 and the upper fixed frame 307 are respectively installed on the lower and upper parts of the vertical support 102. The transmission screw 302 is rotatably connected between the lower fixed frame 306 and the upper fixed frame 307. The second motor 301 is installed on the upper fixed frame 307 and connected to the transmission screw 302. The vertical conveying block 303 is threadedly connected to the transmission screw 302 through the threaded ring 308. The limiting slide rail 305 is installed on the vertical support 102, and the vertical conveying block 303 slides with the limiting slide rail 305. The support foot 304 is installed on the vertical conveying block 303 and is used to support and vertically move the stacked plate 4. The vertical conveying block 303 is configured with... Multiple vertical conveying blocks 303 are arranged at equal intervals along the vertical direction on the same vertical support 102. Each vertical conveying block 303 is threadedly connected to the transmission screw 302 through an independent threaded ring 308. The spacing between adjacent vertical conveying blocks 303 matches the layer spacing of the main frame structure 1 of the device. The limiting slide rail 305 is set on the outside of the lower fixed frame 306 and the upper fixed frame 307. The two sides of the vertical conveying block 303 are respectively provided with sliding grooves. The vertical conveying block 303 slides with the limiting slide rail 305 through the sliding grooves to limit the circumferential rotation of the vertical conveying block 303 and guide it to move in the vertical direction. The upper surface of the support foot 304 is provided with an anti-slip pad layer. The anti-slip pad layer is made of rubber or polyurethane material to increase the friction with the bottom surface of the stacked plate 4 and prevent the stacked plate 4 from slipping during vertical movement.

[0021] During operation, the vertical conveying structure 3 enables independent storage of each layer of the composite slab. Each layer of components is individually supported by support feet 304, avoiding the pressure of upper layers on lower layers in traditional stacking methods. This fundamentally eliminates the quality hazard of cracks caused by localized stress concentration. Simultaneously, the horizontal conveying structure 2, in conjunction with the vertical conveying block 303, can precisely transport the composite slab to designated layers without relying on shims for alignment. This significantly reduces operational difficulty and the risk of components becoming loose or misaligned. Furthermore, the three-dimensional storage method greatly increases the storage capacity per unit area, making it suitable for various specifications. The storage of composite slabs with different grid sizes and irregular shapes solves the limitations of traditional horizontal stacking on the types of components. In addition, during batch transfer, the composite slabs of the target layer can be directly lowered to the horizontal transfer structure 2 for centralized transfer through the vertical conveyor block 303, eliminating the need for individual hoisting and significantly improving construction efficiency. Under the same floor area conditions, it can achieve several times the storage capacity of single-layer flat storage, greatly saving site resources and reducing labor and material costs. It is also suitable for storing composite slabs of different strength stages and different specifications and sizes during the curing period, with wide applicability and significant economic benefits.

[0022] Example 2: Based on Embodiment 1, a stabilizing structure 5 is also included. The stabilizing structure 5 includes a stabilizing frame 501, a positioning ratchet 502, a linkage shaft 503, a stacked plate support 504, a fixing plate 505, a limiting spring 506, and a locking plate 507. The stabilizing frame 501 is mounted on the vertical conveying block 303. The linkage shaft 503 is mounted on the stabilizing frame 501 via a bearing 205. The positioning ratchet 502 is fixedly mounted on the linkage shaft 503. The stacked plate support 504 is fixedly connected to the linkage shaft 503. The fixing plate 505 is mounted on the stabilizing frame 501. The locking plate 507 is connected to the fixing plate 505 via the limiting spring 506. The locking plate 507 is connected to the positioning ratchet. The toothed engagement of 502 is used to lock the tilt angle of the composite plate support 504. The composite plate support 504 is located on the inner side of the outer end of the linkage shaft 503. The positioning ratchet 502 is located between the two composite plate supports 504, and the linkage shaft 503 is connected to the ratchet drive. The locking piece 507 is kept engaged with the positioning ratchet 502 under the action of the limiting spring 506. When the composite plate body 4 is placed on the composite plate support 504, the composite plate support 504 is rotated under force and triggers the automatic locking of the positioning ratchet 502 and the locking piece 507. The end of the locking piece 507 is provided with a wedge-shaped locking head that matches the tooth profile of the positioning ratchet 502. The tilting direction is opposite to the force rotation direction of the positioning ratchet 502, so that the composite plate support leg 504 can only rotate in the supporting direction and cannot rotate in the opposite direction under load. When the composite plate body 4 is placed on the composite plate support leg 504, the composite plate support leg 504 tends to rotate downward under the action of gravity. This rotation is transmitted to the positioning ratchet 502 through the linkage shaft 503. The tooth groove of the positioning ratchet 502 and the locking piece 507 are kept in a locked state under the action of the limiting spring 506, thereby realizing the instant locking of the tilt angle of the composite plate support leg 504, effectively preventing the composite plate body 4 from slipping or overturning due to the rotation of the support leg at the moment of placement or during transportation. Furthermore, the wedge-shaped locking head at the end of the locking piece 507 matches the tooth profile of the positioning ratchet 502, and the tilt direction of the wedge-shaped locking head is opposite to the force rotation direction of the positioning ratchet 502. This means that the composite plate support leg 504 can only rotate in the supporting direction and not in the reverse direction when under load. As the weight of the composite plate body 4 increases, the composite plate support leg 504 rotates tighter and tighter, and the locking piece 507 and the positioning ratchet 502 engage more firmly. This achieves a virtuous cycle where the heavier the composite plate body 4 is, the tighter it is clamped, which greatly enhances the adaptability of the device to composite plates of different weights and specifications and effectively solves the quality hazards of components easily falling out, misaligning, and tipping over in traditional storage methods.
