Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel beam hooks, in particular to a special hook for steel beam hoisting. Background Art
[0002] The steel beam hook is a key equipment for lifting and transferring heavy objects. It is an important component hung on a crane or other lifting equipment. It is used to lift heavy objects and transfer them to the pointing position. It is widely used in factories, docks, logistics centers and other scenes, greatly facilitating the handling and transfer of heavy objects. The steel beam hook is mainly made of alloy steel to ensure that it has sufficient strength and durability. It usually consists of four parts: a hook handle, a hook back, a hook tip and an anti-slip groove locking steel plate. This design enables it to better fix and suspend heavy objects. In China, the specifications and models of steel beam hooks vary, but they must comply with the national standards for hook specifications issued by the state. Common hook specifications include G80, G70 and G43, etc., which are suitable for different lifting capacities and usage scenarios.
[0003] At present, steel beam hooks all adopt a single hook structure design. When hoisting an I-shaped steel plate, only the top edge of the steel plate can be hooked. At this time, it may slip on the hook, posing certain safety hazards in the hoisting construction.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] Example:
[0024] See also Figure 1-3 The present embodiment provides a special hook for steel beam lifting, including an upper hook mechanism 1, the upper hook mechanism 1 includes an upper hook 1 2 and an upper hook 2 3, the upper hook 1 2 and the upper hook 2 3 are rotatably connected, a lower hook mechanism 5 is installed at the bottom of the upper hook mechanism 1, the lower hook mechanism 5 includes a lower hook 1 51 and a lower hook 2 52, the top of the lower hook 1 51 is rotatably connected to the inner bottom of the upper hook 1 2, the top of the lower hook 2 52 is rotatably connected to the inner bottom of the upper hook 2 3, and the steel beam hook is in use. The upper hook 1 2 and the upper hook 2 3 on the upper hook mechanism 1 are used to hook the two sides of the top edge of the I-shaped steel plate, and at the same time, the lower hook 1 51 and the lower hook 2 52 on the lower hook mechanism 5 are used to hook the bottom edge of the I-shaped steel plate. At this time, the top and bottom edges of the I-shaped steel plate can be hooked at the same time. Therefore, during the lifting process, the sliding caused by the traditional hook only hooking the top edge of the I-shaped steel plate is effectively avoided, so that the hook can hook the I-shaped steel plate more stably during lifting, thereby improving the safety of the lifting construction operation.
[0025] In this embodiment, if Figure 1 , Figure 2 and Figure 3As shown, through holes 21 are symmetrically provided at both ends of the top inner side surfaces of the upper hook 1 2 and the upper hook 2 3, and a rotating rod is rotatably connected between the two through holes 21 on the top inner side surface of the upper hook 1 2, and both ends of the rotating rod simultaneously pass through the two through holes 21 on the upper hook 2 3, so the upper hook 1 2 and the upper hook 2 3 are rotatably connected via the rotating rod, and when the rotating rod is pulled upward, the angle between the upper hook 1 2 and the upper hook 2 3 will be reduced by rotation, thereby increasing the clamping force of the hook.
[0026] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, a connecting tube 22 is rotatably connected between the inner side surfaces of the upper hook 2 and the upper hook 2, and threaded holes 23 are opened between the two sides of the outer ring surface of the connecting tube 3. A screw rod 4 is connected between the two connecting tubes 22 on the upper hook 2 and the upper hook 2, and the screw rod 4 is threadedly connected between the threaded holes 31 on the two connecting tubes 22. A nut 5 is fixedly installed at one end of the screw rod 4. When the screw rod 4 rotates clockwise, the connecting tubes 22 on the upper hook 2 and the upper hook 23 approach each other, and when the screw rod 4 rotates counterclockwise, the connecting tubes 22 on the upper hook 2 and the upper hook 23 move away from each other. Therefore, by rotating the screw rod 4, the distance between the connecting tubes 22 on the upper hook 2 and the upper hook 23 can be adjusted, so that the angle between the upper hook 2 and the upper hook 23 can be fixed to prevent the hook from loosening.
[0027] In this embodiment, if Figure 1 As shown, the bottom of the inner side of the upper hook 1 2 and the upper hook 2 3 are both rotatably connected with a sleeve rod 24, and the inner top of the lower hook 1 51 and the lower hook 2 52 are both provided with sleeve holes, and the lower hook 1 51 and the lower hook 2 52 are respectively sleeved and installed on the sleeve rod 24 on the upper hook 1 2 and the upper hook 2 3 through the through holes, so that the lower hook 1 51 and the lower hook 2 52 can rotate on the upper hook 1 2 and the upper hook 2 3
[0028] In this embodiment, if Figure 1 As shown, a connecting tube 2 53 is rotatably connected between the two inner side surfaces of the bottom of the lower hook 1 51 and the lower hook 2 52, and a screw rod 2 54 is threadedly connected between the two connecting tubes 53 on the lower hook 1 51 and the lower hook 2 52. The screw rod 2 54 has the same function as the screw rod 1 4, and can adjust the angle between the lower hook 1 51 and the lower hook 2 52, so that the bottom edge of the steel plate can be hooked tightly.
[0029] Working principle: When the steel beam hook is in use, firstly, the upper hook 1 2 and the upper hook 2 3 on the upper hook mechanism 1 are hooked on both sides of the top edge of the I-shaped steel plate, then the rotation angle of the connecting tube 1 22 is adjusted, and the screw rod 1 4 is screwed on between the two connecting tubes 1 22 inside the upper hook 1 2 and the upper hook 2 3 through the threaded hole 23 to fix the upper hook 1 2 and the upper hook 2 3, and then the lower hook 1 51 and the lower hook 2 52 on the lower hook mechanism 5 are hooked on the bottom edge of the I-shaped steel plate, and the screw rod 2 54 is screwed on between the two connecting tubes 2 53 to fix the angle of the lower hook 1 51 and the lower hook 2 52, at this time, the top and bottom edges of the I-shaped steel plate can be hooked at the same time, so that the sliding caused by the traditional hook only hooking the top edge of the I-shaped steel plate is effectively avoided during the hoisting process, so that the hook can hook the I-shaped steel plate more stably during hoisting, thereby improving the safety of the hoisting construction operation.
