Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and to a novel hoisting structure for side-mounted batch lifting of flat plate components. Background Technology

[0002] In the modern construction industry, prefabricated assembled buildings are widely used. The construction process involves the hoisting and transportation of a large number of prefabricated flat panel components, such as prefabricated wall panels and composite floor slabs. In order to improve construction efficiency, on-site operations require the batch hoisting of multiple flat panel components stacked together. Currently, a common method is to use slings or simple lifting tools to lift or hook the components from the bottom or top. However, when multiple panels are stacked vertically or at an angle, this method will put most of the weight on the bottom few components, and the hoisting force cannot be evenly distributed to each component.

[0003] This uneven stress state can easily cause the bottom plate component to crack, chip, or even break due to excessive compressive stress, resulting not only in the scrapping of the component and economic losses, but more seriously, it brings huge safety hazards.

[0004] Therefore, this utility model proposes a novel hoisting structure for side-mounted batch lifting of flat plate components to address the shortcomings of existing technologies. Summary of the Invention

[0005] In view of the problems existing in the prior art, such as uneven stress leading to easy damage to the bottom components, and cumbersome assembly and disassembly of the lifting equipment and components, resulting in low turnover efficiency, this utility model aims to provide a new type of side-mounted lifting structure for batch lifting of flat plate components that has been improved and can effectively solve the above problems.

[0006] This utility model provides a novel hoisting structure for side-mounted batch lifting of flat plate components, including lifting lugs, lifting rings, sliding strips, fixing plates, high-strength bolts, and threaded sleeves.

[0007] The hoisting structure uses lifting lugs as its main frame. The upper surface of the lifting lugs has circular holes for installing lifting rings, while the side walls of the lugs have hoisting holes for connecting components. The key innovation of the structure lies in the sliding groove on one side of the lifting lug. A sliding strip can slide freely within the groove, and one end of the sliding strip is fixedly connected to a fixing plate. This fixing plate is configured to engage with adjacent flat components during hoisting.

[0008] In terms of connection assembly, the high-strength bolts are designed to be detachably passed through the lifting holes on the lifting lugs and to be threadedly connected to the threaded sleeves with internal threads that are pre-installed on the flat plate component to be lifted. In this way, the lifting lugs and the flat plate component are tightly fixed together to form a stable and reliable overall lifting unit.

[0009] Preferably, to further enhance the reliability of the connection, the end of the high-strength bolt is also connected to a nut by thread, and a washer is provided between the nut and the side wall of the lifting lug. By tightening the nut, the washer can be pressed against the surface of the lifting lug to form a firm locking structure.

[0010] Preferably, in order to achieve batch hoisting of multiple components at one time, multiple hoisting holes can be opened at intervals along the length of the hoisting lug. Each hoisting hole is used to install a connecting assembly consisting of high-strength bolts, nuts and washers to fix multiple flat components at the same time.

[0011] Preferably, as a specific structural form, the slide can be set as a through groove that penetrates the thickness of the side wall of the lifting lug. This design not only simplifies the processing technology, but also facilitates the installation and maintenance of the sliding strip.

[0012] Preferably, to facilitate quick tightening or loosening using standard wrench tools, the head of the high-strength bolt can be designed with a square structure to facilitate the application of torque by the tool.

[0013] Preferably, the sliding strip can be designed as a long strip structure extending along the length of the groove to ensure sufficient sliding stroke and stable guidance within the groove; while the fixing plate can be designed as a flat plate structure perpendicular to the extension direction of the sliding strip. This structure allows it to be inserted between the flat plate components with the maximum contact area, providing a stable and effective isolation effect.

[0014] Preferably, to facilitate quick on-site connection, the threaded sleeve can be designed as a hollow cylindrical structure and pre-embedded or welded to a designated position on the flat component to form a standard connection interface, which greatly improves assembly efficiency.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art of excessive stress and easy damage to the bottom component due to force concentration when hoisting flat components in batches by setting up lifting lugs with multiple lifting holes and using high-strength bolts to connect to threaded sleeves pre-set on the flat component. It achieves the technical effect of making each flat component uniformly stressed and lifting safely and reliably.

[0016] This utility model solves the problem of flat components colliding with each other due to shaking during hoisting and causing damage to the edges of the components by opening a sliding groove on the lifting lug and setting a fixing plate connected to the sliding strip. It achieves the technical effect of effectively isolating and stabilizing each component and improving the safety of hoisting.

[0017] This utility model solves the problem of inconvenient connection and disassembly of existing lifting tools and components, which affects the efficiency of lifting tool turnover, by adopting a detachable threaded connection method of high-strength bolts and threaded sleeves. It achieves the technical effect of simple structure, convenient assembly and disassembly, and reusable lifting tool. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figures 1 to 4 This utility model provides a novel hoisting structure for side-mounted batch lifting of flat plate components, including a lifting lug 1 as the main frame, a circular hole 2 on the upper surface of the lifting lug 1, a lifting ring 3 passing through the circular hole 2 for overall hoisting, and a hoisting hole 4 on the side wall of the lifting lug 1; the hoisting structure is constructed in that a sliding groove 5 is also provided on one side of the lifting lug 1, a sliding strip 6 is slidably connected in the sliding groove 5, and a fixing plate 7 is fixedly connected to one end of the sliding strip 6. The fixing plate 7 is configured to be used to engage between adjacent flat plate components during hoisting to play a role in isolation and stability; the structure further includes a high-strength bolt 8 and a threaded sleeve 11, the high-strength bolt 8 is detachably passed through the hoisting hole 4 and cooperates with the threaded sleeve 11 which is pre-installed on the flat plate component to be hoisted and is threadedly connected to the high-strength bolt 8, thereby fixing the lifting lug 1 to the flat plate component.

[0022] Please refer to Figure 3 and Figure 4 The head of the high-strength bolt 8 is square to facilitate the application of torque by tools. When fixing the flat plate component, the high-strength bolt 8 passes through the lifting hole 4 opened on the side wall of the lifting lug 1 and is threaded to the threaded sleeve 11 that is pre-embedded or welded into the flat plate component. At the same time, a washer 10 and a nut 9 are sequentially fitted at the end of the high-strength bolt 8. By tightening the nut 9, the washer 10 is fixed to the side wall of the lifting lug 1 by compression. This connection method consisting of the high-strength bolt 8, nut 9, washer 10 and threaded sleeve 11 achieves a firm and repeatedly detachable fixation between the lifting lug 1 and the flat plate component.

[0023] Please refer to Figure 1 and Figure 2 The groove 5 on one side of the lifting lug 1 is a through groove that penetrates the thickness of the side wall; the sliding strip 6 is a long strip-shaped structure that extends along the length of the groove 5 and is slidably connected inside the groove 5; the fixing plate 7 is a flat plate-shaped structure that is perpendicular to the extension direction of the sliding strip 6 and is fixedly connected to one end of the sliding strip 6; when multiple flat plate components are fixed on the lifting lug 1, the fixing plate 7 is located between two adjacent flat plate components. Through the adaptive sliding of the sliding strip 6 in the groove 5, it plays a role in separating and buffering the flat plate components, preventing direct contact and collision of the components during the lifting process.

[0024] In a preferred embodiment, in order to achieve batch hoisting, multiple hoisting holes 4 are provided on the hoisting lug 1 along the length direction. Each hoisting hole 4 is used to install high-strength bolts 8, so that multiple flat components can be connected and fixed at the same time.

[0025] As another preferred embodiment, please refer to Figure 4 The head of the high-strength bolt 8 has a square structure to facilitate the application of torque by tools. The end is connected to a nut 9 by a thread. A washer 10 is also provided between the nut 9 and the side wall of the lifting lug 1. By tightening the nut 9, the washer 10 can be pressed onto the lifting lug 1, further enhancing the stability of the connection.

[0026] In one specific embodiment, in order to ensure the flexibility and stability of the movement of the fixed plate 7, the slide groove 5 is designed as a through groove that penetrates the thickness of the side wall of the lifting lug 1, and the sliding strip 6 is a long strip structure that extends along the length direction of the slide groove 5. The fixed plate 7 is a flat plate structure that is perpendicular to the extension direction of the sliding strip 6 and is fixedly connected to the sliding strip 6.

[0027] In one specific embodiment, the threaded sleeve 11 is a hollow cylindrical structure, which is pre-embedded or welded to a predetermined position on the flat plate component. The inner wall is machined with threads that match the high-strength bolt 8 to facilitate quick alignment and screw-in connection.

[0028] Working principle: When it is necessary to lift the flat plate component, the high-strength bolt 8 is passed through the lifting hole 4 on the lifting lug 1 and screwed into the threaded sleeve 11 that is pre-fixed on the flat plate component. Then, the high-strength bolt 8 is locked on the lifting lug 1 from the other side using the nut 9 and washer 10. By repeating this operation, multiple flat plate components can be firmly fixed on the lifting lug 1, realizing a reliable connection between the lifting tool and the component.

[0029] During the process of connecting and fixing the flat plate components, the fixing plate 7 connected to the sliding bar 6 will be placed between adjacent flat plate components due to its own weight or manual adjustment, by sliding the sliding bar 6 in the sliding groove 5. The fixing plate 7 plays a role in separating and limiting each flat plate component, preventing shaking and collision during lifting and transportation. After all components are fixed, the lifting ring 3 located on the upper surface of the lifting lug 1 can be hooked by the lifting equipment to realize the synchronous lifting of the entire batch of flat plate components.

[0030] The structure, through the ingenious spacing design of the lifting holes 4 on the lifting lug 1, allows each flat component to bear the lifting force independently and evenly, effectively avoiding the problem of excessive force on the bottom component in the traditional stacking lifting method; at the same time, the detachable connection between the high-strength bolt 8 and the threaded sleeve 11 allows the lifting tool to be easily disassembled and reused after the lifting task is completed, improving work efficiency.
