[0001] This invention relates to the field of lifting equipment technology, specifically to an automatic lifting equipment for H-beams based on a swing guide rod and a gravity sliding mechanism. Background Technology

[0002] H-beams play a crucial role in many fields. During hoisting, they are typically lifted using a lifting beam in conjunction with chains and ram's horn hooks, lifting 1-4 bundles of goods at a time. The hooking and unhooking operations are performed by the signalman / slinger. However, with this type of lifting equipment, if the goods move while unhooking, the signalman / slinger is at risk of injury. Furthermore, if the goods collide or one end tilts during hoisting, there is a risk of them falling, potentially resulting in objects falling from a height. Summary of the Invention

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] Example

[0044] like Figures 1-4 As shown, this embodiment proposes...

[0045] An automatic lifting device for H-beams based on a swing guide rod and a gravity sliding mechanism includes:

[0046] The steel wire rope 1 is of several kinds, and one end of each steel wire rope 1 is used to be mounted on the hoisting device. It also includes:

[0047] Frame 2 has several mounting bases 3, and the other ends of several steel wire ropes 1 are respectively set on several mounting bases 3;

[0048] The hook assembly 4 has two hook assemblies, which are slidably disposed at both ends of the frame 2, and the two hook assemblies 4 form a clamping space.

[0049] Adjustment component 5, adjustment component 5 includes:

[0050] A rotating shaft 6 is rotatably mounted on a frame 2, and two hook assemblies 4 are respectively hinged on both sides of the rotating shaft 6;

[0051] Turntable 7 is mounted on rotating shaft 6. After the turntable 7 rotates, it is used to drive the two hook assemblies 4 to move closer or further apart through rotating shaft 6.

[0052] The center rope 8 has one end movable on the turntable 7 and the other end is used to be set on the lifting device. The center rope 8 is used to drive the turntable 7 to rotate.

[0053] In this embodiment, since H-beams are used more and more frequently, and existing methods require slingers to perform hook and unhook operations during the hoisting process, this poses a life-threatening risk to signalmen. Furthermore, if a collision occurs or one end of the goods is tilted during hoisting, there is a risk of the goods falling, resulting in objects falling from a height. Therefore, this solution uses a steel wire rope 1 suspended on the mounting base 3 of the frame 2. The frame 2 has a hook assembly 4, and the turntable 7 rotates under the weight of the frame 2 itself. The rotating shaft 6 drives the hook assembly 4 to clamp, thereby realizing the hoisting of H-beams by gravity, reducing the risk of objects falling from a height, and achieving unmanned clamping of H-beams during the hoisting process.

[0054] Furthermore, adjustment component 5 also includes:

[0055] There are two pull plates 9, both of which are set on the rotating shaft 6 and located at both ends of the rotating shaft 6 respectively. Both hook assemblies 4 are hinged on the rotating shaft 6 through the pull plates 9.

[0056] In this embodiment, in order to increase the sliding action of the rotating shaft 6 on the hook assembly 4 when the turntable 7 rotates, a pull plate 9 is provided. The pull plate 9 is located on both sides of the rotating shaft 6. The hook assembly 4 and the pull plate 9 are hinged together. When the turntable 7 rotates under the action of gravity, the rotating shaft 6 can maximize the sliding distance of the hook assembly 4 within a limited rotation stroke, making the hook assembly 4 more stable when clamping H-shaped steel.

[0057] Furthermore, frame 2 has a guide channel, and hook assembly 4 includes:

[0058] Gripper 10 is slidably mounted on frame 2.

[0059] There are two guide rods 12, which are slidably disposed in the guide channel, with one end respectively disposed at both ends of the gripper 10;

[0060] There are two adjusting rods 11. One end of each adjusting rod 11 is hinged to one end of each of the two pull plates 9, and the other end is hinged to the other end of each of the two guide rods 12.

[0061] In this embodiment, to make the clamp 21 more stable during clamping, the solution is provided with a guide rod 12 and an adjusting rod 11. Both the guide rod 12 and the adjusting rod 11 are located in the adjustment channel. The rotating shaft 6 adjusts the adjusting rod 11 by rotating it. The adjusting rod 11 and the guide rod 12 are hinged together, so that the adjusting rod 11 does not affect the level of the guide rod 12 during the adjustment process, so that the clamp 21 can slide smoothly with the guide rod 12.

[0062] Furthermore, Framework 2 includes:

[0063] The crossbeam 13 has two parts, and several mounting seats 3 are respectively disposed on the two crossbeams 13 and located at both ends of the two crossbeams 13. Two guide rods 12 are respectively slidably disposed on the two crossbeams 13.

[0064] The longitudinal beams 14 are arranged at intervals on the two transverse beams 13, and each of the longitudinal beams 14 has through holes 15 at both ends, forming a guide channel.

[0065] In this embodiment, in order to increase the stability of the frame 2, the frame 2 is formed by a crossbeam 13 and a longitudinal beam 14. The frame 2 is more stable and reliable under the action of the crossbeam 13 and the longitudinal beam 14. Several through holes 15 are provided on the longitudinal beam 14 to form a guide channel. The guide rod 12 and the adjusting rod 11 are both located in the guide channel. The guide rod 12 slides in the through hole 15, so that the guide rod 12 can only slide horizontally, which ensures the stability when clamping H-shaped steel.

[0066] Furthermore, the turntable 7 has a sliding hole 16, and both ends of the sliding hole 16 have slots 17. The adjustment assembly 5 also includes:

[0067] The center rope 8 is movably mounted on the turntable 7 via the snap-fit ​​component 18. The snap-fit ​​component 18 has a snap-fit ​​end, which is slidably mounted in the sliding hole 16. After the snap-fit ​​end slides, it is used to snap into the two slots 17. After the snap-fit ​​end slides, it is used to adjust the rotation of the turntable 7.

[0068] In this embodiment, in order to enable the turntable 7 to adjust the rotation of the shaft 6 under the action of gravity and to have a stable effect after adjustment, the turntable 7 is provided with a sliding hole 16 and a slot 17. The snap-fit ​​part 18 can slide in the sliding hole 16 and is located in the two slots 17 after sliding. After being snapped into the slot 17, the slot 17 will exert a force on the snap-fit ​​part 18 to prevent the snap-fit ​​part 18 from sliding in the sliding hole 16 during hoisting.

[0069] Furthermore, adjustment component 5 also includes:

[0070] Spring 19, the center rope 8 is set on the snap-fit ​​18 through spring 19.

[0071] In this embodiment, in order to achieve balance in hoisting at different hoisting heights, and to ensure that the central rope 8 can be stressed and the turntable 7 can be adjusted, a spring 19 is provided to compensate for changes in the length of the central rope 8 based on the elastic force of the spring 19.

[0072] Furthermore, the gripper 10 includes:

[0073] Sliding element 20 is slidably mounted on crossbeam 13;

[0074] The clamp 21 has several hooks spaced apart on the sliding member 20.

[0075] Furthermore, the clamp 21 has a clamping groove 22 and a guide slope 23 at the bottom end of the clamp 21.

[0076] In this embodiment, in order to enable the clamp 21 to smoothly penetrate into the interior of the H-shaped steel during the clamping process, the solution provides guide slopes 23 at the bottom end and the side of the clamp 21.

[0077] Furthermore, the crossbeam 13 is provided with several reinforcing ribs 24, which are located at the bottom end of the sliding member 20.

[0078] In this embodiment, in order to increase the strength of the lifting device, several reinforcing ribs 24 are provided at the bottom end of the sliding member 20 to enhance the strength of the lifting device.

[0079] Furthermore, it also includes:

[0080] There are two guide plates 25, which are respectively set at the bottom of both sides of the frame 2 and located at the lower end of the gripper 10. The two guide plates 25 face each other on one side and are inclined.

[0081] In this embodiment, in order to ensure that the lifting device can be accurately positioned during the lifting process, a guide plate 25 is provided. The guide plate 25 can play a positioning assistance role during the positioning of the lifting device.

[0082] Furthermore, the rotating shaft 6 has several disks 26.

[0083] In this embodiment, in order to observe whether the turntable 7 is properly engaged during the lifting process, a disc 26 is provided. For example, when the disc 26 is horizontal, the lifting device is not clamped, and when the disc 26 is vertical, the lifting device is clamped.

[0084] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
