Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to an adjustable steel bar truss floor deck hoisting device. Background Art

[0002] In modern building construction, steel truss floor decks are important structural components. The efficiency and safety of their handling and flipping operations directly affect the project progress and construction quality. Traditional handling and flipping methods often rely on manual or simple mechanical equipment, which can easily lead to inconvenient operation, low efficiency, and even safety hazards. Therefore, a more efficient and safe lifting equipment is urgently needed.

[0003] To this end, a lifting device specifically for handling and flipping steel truss floor decks has been developed in the prior art. The lifting device uses a U-shaped metal lifting frame as the main supporting structure, combined with an advanced motor drive system and flipping mechanism, to achieve fast and safe handling and flipping of steel truss floor decks. By driving the motor in the chassis to drive the lifting rotating wheel, the lifting flipping belt can be easily connected to both ends of the deck, achieving precise control and stable flipping of the deck. When this steel truss floor deck handling and flipping lifting device lifts, transports and flips the steel truss floor deck through multiple lifting and flipping belts, it is necessary to put the bottom end of the lifting and flipping belts on the outside of the steel truss floor deck. Then, when the lifting device rises, the entire steel truss floor deck will be lifted by the lifting and flipping belts. However, in the process of transporting or flipping the steel truss floor deck through the lifting and flipping belts, if the center of the steel truss floor deck is biased to the left or right, and the inertia generated after the transport process stops, the steel truss floor deck in the hoisting state will cause a large degree of shaking. This will not only easily cause the hoisted steel truss floor deck to fall and be damaged, but also easily cause a large degree of shaking, causing the steel truss floor deck to collide with the outside, all of which will easily damage the steel truss floor deck. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is that in the process of transporting or flipping the steel truss floor deck by the lifting and flipping belt, if the center of the steel truss floor deck is biased to the left or right, and the inertia generated after the transport process stops, it will cause the steel truss floor deck in the hoisting state to shake significantly, thereby providing an adjustable steel truss floor deck hoisting device.

[0038] The adjustable steel truss floor deck hoisting device can drive the steel truss floor deck on the flipping belt to flip when the steel truss floor deck is hoisted on the flipping belt by driving the flipping belt to rotate through the driving motor; after the steel truss floor deck is hoisted on the flipping belt, the depth of the flipping belt in the limit frame 13 is adjusted by adjusting the height position of the limit frame 13 on the suspension rod 15, and is adjusted to an appropriate position so that the flipping belt can be more tightly hoisted to the steel truss floor deck, thereby improving the stability during transportation and flipping, and preventing the steel truss floor deck from being loosely fixed during hoisting. No shaking occurs during transportation and flipping; a driving motor is used to drive the flipping belt to rotate to drive the steel truss floor deck to flip, so that stable operation can be maintained under high load conditions, ensuring efficient, reliable, precise and flexible transportation and flipping, and the motor-driven flipping is easy to control, and the speed and direction can be changed quickly, and the hoisted steel truss floor deck will not shake due to inertia during transportation and flipping; the setting of the stabilizing mechanism 3 enables the device to be flexibly adjusted according to the size of the transported steel truss floor deck, ensuring stability during transportation and flipping.

[0039] In this embodiment, the cross section of the hanging frame 6 is U-shaped, and sealing plates 12 are fixed to both ends of the hanging frame 6. Such an arrangement can enhance the structural strength and enable the hanging frame 6 to bear a greater weight.

[0040] In this embodiment, a plurality of inner support frames 7 are equidistantly arranged inside the hanging frame 6. Such arrangement can strengthen the structural strength of the hanging frame 6 and prevent the hanging frame 6 from being deformed due to overload.

Such a configuration can ensure stability during hanging. In an alternative embodiment, three hanging plates 8 can also be provided, and the three hanging plates 8 are evenly spaced and arranged on the top of the hanging frame 6. In an alternative embodiment, the number of hanging plates 8 can be adjusted according to demand, and the number is not less than two.

[0042] In this embodiment, the flip mechanism also includes a first drive chassis 11 and a second drive chassis 4 fixed to opposite ends of the bottom of the hanging frame 6 and symmetrically arranged, the two drive motors are respectively a first drive motor arranged in the first drive chassis 11 and a second drive motor arranged in the second drive chassis 4, the output shaft of the first drive motor is connected to a first rotating wheel 10, the output shaft of the second drive motor is connected to a second rotating wheel 5, and the two flip belts are respectively a first flip belt 1 connected to the first rotating wheel 10 and a second flip belt 2 connected to the second rotating wheel 5. The motor-driven mode allows the handling and flipping operations to be performed simultaneously, simplifies the construction process, saves time and manpower, and improves construction efficiency.

[0043] Specifically, anti-slip protrusions are provided on the inner sides of the first flip belt 1 and the second flip belt 2. Such a configuration can enhance the friction between the flip belt and the steel truss floor deck, ensure the stability of the steel truss floor deck during transportation and flipping, and prevent the steel truss floor deck from slipping off the flip belt during transportation and flipping.

[0044] In this embodiment, the limit frame 13 is connected to the suspension rod 15 through a support plate 14 , one end of the support plate 14 is fixedly connected to the limit frame 13 , and the other end of the support plate 14 is provided with a sleeve hole 17 , and the support plate 14 is sleeved on the outer periphery of the suspension rod 15 through the sleeve hole 17 .

[0045] Specifically, the limit frame 13 is a strip frame, and the width of the hole of the limit frame 13 is the same as the width of the flip belt. In this way, the limit frame 13 can be used to limit and guide the flip belt to avoid twisting of the flip belt, and the stability of the flip belt can be ensured when transporting and flipping the steel truss floor deck.

[0046] In this embodiment, a plurality of positioning holes 16 arranged along the vertical direction are evenly spaced on the suspension rod 15, and a screw hole corresponding to the positioning hole 16 is formed on the end surface of the support plate 14 away from the limit frame 13, and a hand screw 18 is threadedly connected to the screw hole.

This arrangement can effectively prevent the support plate 14 from slipping off the suspension rod 15.

[0048] To sum up, in this adjustable steel truss floor deck lifting device, when the steel truss floor deck is hoisted on the flipping belt, the steel truss floor deck on the flipping belt can be flipped by driving the flipping belt to rotate by the driving motor; after the steel truss floor deck is hoisted on the flipping belt, the depth of the flipping belt in the limit frame 13 is adjusted by adjusting the height position of the limit frame 13 on the hanging rod 15, and adjusted to an appropriate position so that the flipping belt can be more tightly hoisted to the steel truss floor deck, thereby improving the stability during transportation and flipping, and avoiding the steel truss floor deck from being too loose due to hoisting and fixing. However, shaking occurs during the transportation and turning process; the driving motor is used to drive the turning belt to rotate to drive the steel truss floor deck to turn over, so that stable operation can be maintained under high load conditions, ensuring efficient, reliable, precise and flexible transportation and turning, and the motor-driven turning is easy to control, and the speed and direction can be changed quickly, and the hoisted steel truss floor deck will not shake due to inertia during transportation and turning; the setting of the stabilizing mechanism 3 enables the device to be flexibly adjusted according to the size of the transported steel truss floor deck, ensuring stability during transportation and turning.
