Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, and more specifically, relates to a rapid transfer device for prefabricated components of assembled buildings. Background Technology

[0002] Prefabricated construction is an industrialized construction method that assembles prefabricated components such as wall panels, beams, columns, stairs, and balconies into a whole on the construction site. Compared with cast-in-place construction, prefabricated construction can significantly shorten the on-site construction period, reduce environmental pollution, and improve quality control. However, prefabricated components are usually large in size, heavy in weight, and have significant differences in shape and size. The short-distance transportation between the factory workshop and the construction site becomes a critical link in the prefabricated construction process. If the on-site transportation efficiency is low, the flexibility is poor, or the safety is insufficient, it will not only prolong the assembly time, but may also cause component damage or safety accidents, thus negating the efficiency advantages of prefabricated construction itself.

[0003] Currently, the mainstream methods for handling precast components on-site mainly include the following categories: The first category is the use of bridge or gantry cranes in conjunction with flatbed trucks. The components are first lifted using a lifting device, placed on a flatbed truck, and then moved horizontally by a tractor. The second category is the forklift direct-pickup method, where forklifts, by modifying long forks or using specialized booms, directly lift the components off the ground for transport. The third category is the simple roller or railcart method, where the components are placed on rollers or railcars and then moved by pushing, pulling, or traction. Their common technical characteristics are reliance on a single lifting device for hoisting, with horizontal displacement mainly relying on vehicle movement or manual pushing; the clamping or support of components typically uses rigid wooden blocks or fixed lifting devices, limiting their adaptability.

[0004] The above solutions can achieve component transfer to a certain extent, but they still have the following limitations. First, lifting tools, forks, or trolleys are often designed for a single size. When the component size changes significantly, it is necessary to frequently change auxiliary tools or adjust the position of the device, resulting in long waiting times. Second, lifting, placing, and moving actions are completed sequentially, resulting in long operation times. Moreover, the travel route needs to avoid the blind spots of fixed lifting equipment, making smooth operation difficult. Finally, bridge cranes are limited by the coverage area of ​​the rails, and forklifts need to reserve a large travel channel. Once the rollers or rails are laid, it is difficult to adjust the work position, resulting in insufficient flexibility. Utility Model Content

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a rapid transfer device for prefabricated building components. It achieves equidistant linkage of clamping components through a sliding platform with a double-threaded screw synchronous adjustment mechanism. The device switches between flat storage and vertical clamping states via a flip-up frame structure and a limiting pivot of the lifting platform. A closed-loop lifting system formed by a conveyor belt and vertical slide rail drives the lifting platform, enabling rapid positioning, stable lifting, and safe transfer of prefabricated components of different sizes.

[0006] To achieve the above objectives, this utility model provides a rapid transfer device for prefabricated components of assembled buildings, comprising:

[0007] A sliding platform, comprising a base and a support plate disposed on the base;

[0008] A slide seat is provided on the base, the slide seat includes a support plate that matches the support plate, and a screw clamping mechanism;

[0009] The upright frame mounted on the slide includes a fixed seat fixedly connected to the support plate, a rotating seat rotatably connected to the fixed seat via a rotating shaft, a vertical slide rail mounted on the rotating seat, and a lifting platform slidably connected to the vertical slide rail.

[0010] Furthermore, the support frame includes a clamping device disposed between the vertical slide rail and the lifting platform.

[0011] Furthermore, the support frame includes side columns and a center column.

[0012] Furthermore, the support frame includes transmission rods respectively located at its top and bottom ends.

[0013] Furthermore, the support frame includes a conveyor belt that matches the drive rod.

[0014] Furthermore, the sliding platform includes slide rails disposed on both sides of the base.

[0015] Furthermore, the sliding platform includes a double-threaded lead screw disposed between the lead screw clamping mechanisms.

[0016] Furthermore, the slide includes a groove that matches the slide rail.

[0017] Furthermore, both the slide rail and the vertical slide rail are equipped with motors.

[0018] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0019] (1) The device of this utility model achieves integrated operation of "automatic equidistant clamping - horizontal lifting - flipping and storage" by cooperating with the horizontal clamping mechanism of "sliding platform - double threaded screw - symmetrical upright" and the vertical lifting mechanism of "limiting rotating shaft - conveyor belt - lifting platform". The left and right slides are driven to move synchronously by the double threaded screw, and the spacing of the upright can be quickly adjusted according to the width of the prefabricated component without the need for manual measurement and shim fine adjustment.

[0020] (2) The lifting platform of this utility model is composed of a closed-loop synchronous drive system consisting of a conveyor belt and a vertical slide rail to achieve the stability and reliability of the lifting process. The platform automatically maintains a horizontal posture during operation, effectively avoiding component off-center loading, slippage and collision, and improving the overall safety and operation quality of component transfer.

[0021] (3) The upright frame of this utility model can be flipped and the lifting platform can be matched with the limit rotating shaft structure. The lifting platform can be flipped upward around the limit rotating shaft and automatically positioned by the mechanical stop. When it is stored, it is close to the upright frame to compress the minimum passing height, so that the overall thickness and passing height of the device are compressed to the minimum when it is not in operation, which effectively improves the passability and adaptability of the equipment in vertical limited, narrow passages or temporary storage yards.

[0022] (4) The device of this utility model solves the pain points of existing on-site transfer equipment with small clamping stroke, large passing height, complicated manual operation and easy damage to the surface of components. All clamping, lifting and flipping actions of the whole machine can be completed by a single person through a button, without the need for multiple processes, effectively reducing the intensity of manual labor, improving the automation level of logistics in prefabricated buildings, significantly improving overall operating efficiency and excellent safety performance.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figures 1-4 As shown, this utility model embodiment provides a rapid transfer device for prefabricated building components. The device includes a sliding platform 5, two sets of uprights 4, and a lifting platform 48 located on opposite sides of the two uprights 4. The sliding platform 5 is set on the ground and achieves omnidirectional movement via casters 8. The uprights 4 are used to laterally clamp the prefabricated component 1. The lifting platform 48 is used to vertically lift the prefabricated component 1. Rotating the uprights 4 to a flat position pushes the sliding platform 5 into the channel between the prefabricated component 1 and the wooden support 2. Flipping the uprights 4 to a vertical working state, the motor 6 is started, causing the double-threaded screw 51 to move the slide block 3 towards the center until the inner side of the uprights 4 is against the prefabricated component 1. Continuing to drive the motor 6, the lifting platform 48 is raised along the vertical slide rail 43 via the sprocket pair and two conveyor belts 47, lifting the prefabricated component 1 off the wooden support 2. Unlocking the casters 8, the device is pushed to the target position, and the placement, clamping, and storage actions are performed in reverse order to complete the transfer. The device of this utility model achieves integrated operation of "automatic equidistant clamping - horizontal lifting - flipping and storage" through the coordinated cooperation of the horizontal clamping mechanism of "sliding platform - double threaded screw - symmetrical upright" and the vertical lifting mechanism of "limiting rotating shaft - conveyor belt - lifting platform". The double threaded screw synchronously drives the left and right sliding blocks to move, and the upright spacing can be quickly adjusted according to the width of the prefabricated components without the need for manual measurement and shim fine adjustment.

[0030] like Figure 2As shown, the sliding platform 5 includes a base 53, symmetrical support plates 54, and double-threaded screws 51. The base 53 is a rectangular steel frame structure with four casters 8 evenly distributed on its lower surface. Each caster 8 has a foot locking mechanism to ensure stability during clamping or lifting operations. The support plates 54 have a U-shaped cross-section and are symmetrically fixed above the base 53, with a slide rail 52 on each opposite side along its inner wall. The double-threaded screws 51 are longitudinally arranged in the lower grooves of the two support plates 54, with opposite thread directions on the left and right sides. Both ends are supported on the base 53 by bearing seats. The two ends of the screws mesh with a transmission rod 7 via gear pairs, and the transmission rod 7 is connected to a motor 6. The motor 6 can rotate the double-threaded screws 51 by rotating it in both directions, thereby synchronously adjusting the distance between the two sliding seats 3. Two slide blocks 3 are symmetrically slidably mounted on the slide rail 52. Each slide block 3 consists of a support plate 31, a slide groove 32, and a screw clamping mechanism 33. The screw clamping mechanism 33 of each slide block 3 cooperates with the double-threaded screw 51 to achieve equidistant linear motion with the screw 51. The upper end of the slide block 3 is rigidly connected to the fixed seat 45 of the upright frame 4 through the support plate 31.

[0031] like Figure 3 As shown, the support frame 4 includes side columns 41, a central column 42, a vertical slide rail 43, a rotating seat 44, a fixed seat 45, a rotating shaft 46, a conveyor belt 47, a lifting platform 48, and a clamping device 49. The rotating seat 44 and the fixed seat 45 are hinged together via the rotating shaft 46, allowing it to rotate between 0 and 90 degrees: 0 degrees for a flat, stowed state, and 90 degrees for a vertical working state. A vertical slide rail 43 is fixed between the side columns 41 and the central column 42, serving as a guide rail for the lifting platform 48. A transmission rod 7 is installed at the upper and lower ends inside the support frame 4, and the ends of the two transmission rods 7 are synchronously connected via two conveyor belts 47. The output shaft of the motor 6 is connected to the lower transmission rod 7 via a sprocket pair. When the motor 6 operates, it drives the upper and lower transmission rods 7 to rotate synchronously, thereby driving the conveyor belts 47 to rise and fall. The clamping device 49 is fixedly installed at the rear end of the lifting platform 48 and is fixedly connected to the two conveyor belts 47, serving a positioning and anti-sway function during lifting.

[0032] Furthermore, such as Figures 3-4As shown, the lifting platform 48 is horizontally positioned between the two uprights 4. Its bottom edge is fixedly connected to the conveyor belt 47 via a clamping device 49, and its front end is a lifting surface used to support the precast component 1. A limiting pivot is provided between the lifting platform 48 and the clamping device 49, allowing the lifting platform 48 to rotate upwards by 90 degrees, so that the lifting platform 48 is close to the upright 4. In the working state, the lifting platform 48 is limited to a horizontal lifting angle; the up-and-down movement of the conveyor belt 47 drives the lifting platform 48 to rise and fall smoothly within the vertical slide rail 43, realizing the lifting or placement of the precast component 1. When it is necessary to drive the transfer device into the narrow groove at the bottom of the precast component 1, the lifting platform 48 can be manually or electrically rotated upwards by 90 degrees around the limiting pivot until the lifting platform 48 is close to the inner side of the upright 4, significantly improving the device's passability in narrow passages.

[0033] like Figure 4 As shown, in use, the sliding platform 5 is first propelled between the two wooden blocks 2 using the casters 8; then, the flipping mechanism is activated, causing the two sets of uprights 4 to flip from a flat position to a vertical position and align with the side of the precast component 1. Next, the motor 6 drives the double threaded screw 51 to rotate via the transmission rod 7, and the left and right sliding blocks 3 move equidistantly towards the center within the slide rail 52, causing the uprights 4 to clamp and limit the precast component 1; after completing the lateral positioning, the motor 6 drives the conveyor belt system to raise the lifting platform 48 along the vertical slide rail 43, lifting the precast component 1 off the wooden blocks 2 as a whole. At this time, the sliding platform 5 can smoothly transfer the component to the hoisting position while maintaining the clamping state; after reaching the position, the lifting platform 48 is driven in the opposite direction to descend and release the uprights 4, thus completing the placement and detachment operation. Through the above coordinated actions, an integrated closed-loop process of "driving—clamping—lifting—transferring—placement" is realized, which has technical effects such as quickly adjusting the clamping distance, adapting to components of different specifications, reducing the risk of manual handling, and significantly improving the efficiency of on-site logistics.

[0034] Through the above structural design, this device can automatically adjust the clamping distance of the upright 4 and complete the lifting and transfer of prefabricated components 1 in a limited space, significantly improving the efficiency and safety of on-site logistics for prefabricated building components.

[0035] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
