Description

Technical Field

[0001] This invention relates to the field of floor decking hoisting equipment technology, and in particular to a floor decking hoisting anti-detachment and anti-swaying safety device. Background Technology

[0002] Floor decking is a core component in steel structure floor construction, widely used in the pouring of floors in factories, office buildings, and high-rise buildings. Hoisting is a critical step in its construction. Existing floor decking is mostly hoisted by using hooks and hoisting straps to bind the steel truss, which has obvious defects: open hooks lack closed limiters, making them prone to detachment due to wind force and inertia at high altitudes, causing falls; lacking anti-sway and vibration reduction structures, the components are prone to swaying and shaking in the wind, which not only increases the difficulty of high-altitude alignment and reduces construction efficiency, but also causes truss deformation and damage to the decking, affecting the construction quality.

[0003] A search revealed Chinese patent CN210236856U, which discloses an adjustable steel truss floor deck hoisting tool. The tool includes lifting lugs, a crossbeam, connectors, a trapezoidal plate, a hook, connecting holes, bolts, stiffening plates, and hoisting holes. This adjustable steel truss floor deck hoisting tool has a simple structure, is easy to operate, highly practical, and has low processing costs. It can quickly hoist steel truss floor decks, greatly improving hoisting efficiency and ensuring quality and safety.

[0004] Based on the above search and existing technology, the following findings were made:

[0005] Existing technologies lack a hook anti-slip locking structure, making the hook prone to slippage during high-altitude operations; they also lack a shock absorption and sway suppression mechanism, resulting in significant swaying and shaking during hoisting due to wind and start-stop inertia, making high-altitude alignment difficult; furthermore, they lack a center of gravity adjustment and protection structure, which still makes it easy to damage floor deck components during hoisting, resulting in insufficient safety protection capabilities and thus certain limitations. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes a safety device for preventing detachment and swaying during floor decking hoisting. It employs a magnetically sealed hook to prevent detachment during hoisting, and is equipped with a bottom counterweight shock absorber to suppress swaying and shaking. The device features multi-point symmetrical force protection components, is easy to assemble and disassemble, has wide applicability, and effectively improves the safety and construction efficiency of floor decking hoisting operations.

[0007] The technical solution to achieve the purpose of this invention is as follows: a safety device for preventing detachment and swaying during the hoisting of floor decking, comprising a floor decking body and a steel truss, wherein the steel truss is fixedly installed on the surface of the floor decking body, and further comprising a hook assembly, a first steel wire rope, and a hoisting assembly.

[0008] The hook assembly includes lifting hooks that are attached to the outside of the steel truss, and a sealing hook is hinged to the top of the lifting hook;

[0009] The first steel wire rope is fixedly installed at one end of the sealing hook;

[0010] The lifting assembly includes a lifting plate fixedly installed on the top of the first wire rope, and safety hooks are attached to both sides of the steel truss.

[0011] Preferably, an adsorption magnet is fixedly installed on the end face of the lifting hook, a second steel wire rope is fixedly installed on one end of the safety hook, a counterweight shock-absorbing pendulum is provided at the bottom of the floor deck body, and a turnbuckle is fixedly installed between the second steel wire rope and the counterweight shock-absorbing pendulum.

[0012] Preferably, a lifting rod is fixedly installed on the top of the lifting platform, and a crane hanging ring is fixedly installed on the top of the lifting rod.

[0013] The significant advantages of this invention compared to existing technologies are:

[0014] Firstly, this invention adopts a magnetically closed hook anti-detachment structure. The sealing hook and the lifting hook work together, and the magnetic attraction magnets are used to achieve magnetic locking at the port, forming a closed hook cavity. This effectively avoids the risk of traditional open hooks slipping off due to wind force and shaking during the start and stop of the hoisting at high altitudes. It is suitable for steel truss hooking points, achieves anti-detachment throughout the hoisting process, and significantly improves the safety factor of high-altitude hoisting operations.

[0015] Secondly, this invention is equipped with a counterweight shock-absorbing and anti-sway structure. The counterweight shock-absorbing pendulum is suspended at the center of the bottom of the floor deck, which can lower the overall center of gravity of the hoisting. With the help of the inertial damping of the counterweight itself, it can counteract the disturbance of high-altitude wind force and the horizontal sway and vertical shaking caused by the start and stop of the hoisting equipment, reduce the swing amplitude of the floor deck hoisting, reduce the difficulty of high-altitude alignment and installation, and effectively improve the work efficiency of on-site construction and installation.

[0016] Thirdly, this invention has excellent comprehensive performance. The multi-point symmetrical lifting force form can protect the components and avoid deformation of the steel truss and bending damage to the floor deck. The device is easy to assemble and disassemble. The wire rope has a wear-resistant coating, which is highly durable and can be adapted to various specifications of steel truss floor decks. The manufacturing cost is low and the applicable scenarios are wide, which can well meet the actual hoisting operation needs of the construction site.

[0017] This invention addresses the problems of existing technologies lacking a hook anti-slip locking structure, which makes hooks prone to slippage during high-altitude operations; lacking a shock absorption and sway suppression mechanism, resulting in significant swaying and shaking during hoisting due to wind and start-stop inertia, making high-altitude alignment difficult; and lacking a center of gravity adjustment and protection structure, which still easily damages floor deck components during hoisting, resulting in insufficient safety protection capabilities.

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.

[0026] This invention provides an improved anti-detachment and anti-sway safety device for floor decking hoisting. The technical solution of this invention is as follows:

[0027] Example 1

[0028] like Figure 1 As shown, a floor decking hoisting anti-detachment and anti-sway safety device includes a floor decking body 1 and a steel truss 2. The steel truss 2 is fixedly installed on the surface of the floor decking body 1. It also includes a hook assembly 5, a first steel wire rope 4, and a hoisting assembly 3.

[0029] The hook assembly 5 includes a lifting hook 502 that is attached to the outside of the steel truss 2, and a sealing hook 501 is hinged to the top of the lifting hook 502;

[0030] The first steel wire rope 4 is fixedly installed at one end of the sealing hook 501;

[0031] The lifting assembly 3 includes a lifting plate 301 fixedly installed on the top of the first wire rope 4, and safety hooks 7 are attached to both sides of the steel truss 2, which are secure, easy to assemble and disassemble, and highly safe.

[0032] Example 2:

[0033] Based on the first embodiment of this application which provides a safety device for preventing detachment and swaying during floor decking hoisting, the second embodiment of this application proposes another safety device for preventing detachment and swaying during floor decking hoisting. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0034] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] like Figures 2-4 As shown, an adsorption magnet 503 is fixedly installed on the end face of the lifting hook 502. The adsorption magnet 503 attracts and limits the sealing hook 501 and the lifting hook 502 port to achieve magnetic sealing and anti-detachment. A second steel wire rope 6 is fixedly installed on one end of the safety hook 7. A counterweight shock-absorbing pendulum 8 is set at the bottom of the floor deck body 1. A turnbuckle 9 is fixedly installed between the second steel wire rope 6 and the counterweight shock-absorbing pendulum 8. The turnbuckle 9 can adjust the height of the pendulum off the ground to avoid collision with the ground or the installed structure.

[0036] As a further embodiment of the present invention, a lifting rod 302 is fixedly installed on the top of the lifting platform 301, and a crane hanging ring 303 is fixedly installed on the top of the lifting rod 302, which facilitates quick docking and installation with lifting equipment.

[0037] Specific working method: Before starting the operation, connect and fix the lifting equipment head to the lifting ring 303 of the lifting assembly 3; the operator opens the lifting hook 502 in the hook assembly 5, hooks the lifting hook 502 onto the steel truss 2 members around the surface of the floor deck slab body 1, resets the hinged sealing hook 501, and relies on the magnetic attraction magnet 503 on the end face of the lifting hook 502 to lock it, forming a closed hook cavity, completing multi-point anti-detachment hooking. Then, the safety hook 7 is snapped and fixed to both sides of the steel truss 2, and multiple second steel wire ropes 6 are connected to the safety hook 7 and the counterweight shock absorber 8 respectively. The tension of the second steel wire ropes 6 is adjusted by the turnbuckle 9 so that the counterweight shock absorber 8 is suspended at the bottom center position of the floor deck slab body 1. The second steel wire ropes 6 are made of manganese phosphate wear-resistant coated steel wire rope to improve wear resistance and corrosion resistance. After all components have been inspected and confirmed to be securely attached, the lifting equipment is started. The entire structure is lifted and transported via the lifting platform 301 and the first wire rope 4. The magnetic locking hook prevents the hook from coming off at high altitude, and the bottom counterweight shock absorber 8 uses its own inertia to counteract the swaying and shaking caused by wind and starting and stopping, achieving stable lifting and high-altitude positioning and installation. After the lifting and positioning work is completed, the safety hook 7 and the lifting hook 502 are locked in sequence, the entire set of safety devices is removed, and the lifting operation is completed.

[0038] The technical means disclosed in this invention are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this invention are common knowledge to those skilled in the art.
