Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel hoisting device. Background Technology

[0002] In existing technologies, steel plates are widely used in industries such as building construction, shipbuilding, and bridge construction due to their advantages such as high hardness, good stability, wear resistance, and strong corrosion resistance. Currently, when steel plates need to be installed, cranes and lifting clamps are generally used to move the steel plates.

[0003] In actual use, the connection plate and the lifting clamp plate require six high-strength bolts to be fixed, and special tools are needed to tighten the bolts during fixing. This results in a slow assembly speed for the entire lifting clamp, which significantly reduces the lifting efficiency of steel. Moreover, during the lifting process, especially in the lifting of high-rise buildings, the long lifting time or collision with surrounding objects may cause the steel plate to fall, posing a significant safety hazard. Summary of the Invention

[0004] The purpose of this utility model is to provide a steel hoisting device that can stably clamp the steel to be hoisted and improve the safety of the hoisting process.

[0005] This utility model is implemented as follows: A steel hoisting device includes a connecting box. Vertical grooves are provided on opposite sides of the connecting box. A connecting shaft is provided inside the connecting box, with each end of the connecting shaft passing through one of the two grooves. The width of each end of the connecting shaft is greater than the width of the groove. A lifting ring is rotatably connected to the surface of the connecting shaft. A first connecting rod and a second connecting rod are rotatably connected to the bottom of each lifting ring. The top ends of the first and second connecting rods are both located inside the connecting box. A hoisting clamp is connected to the bottom end of both the first and second connecting rods. A square groove for placing steel is provided inside the hoisting clamp, and the square grooves on the two hoisting clamps are arranged opposite each other.

[0006] Optionally, the bottom end of the lifting clamp is connected to multiple bolts, the top of which passes through the lifting clamp and is inserted into the square groove.

[0007] Optionally, a pad is provided at the bottom of the inside of the square groove, and the surface of the pad is provided with a threaded through hole that matches the bolt. The bolt is screwed into the threaded through hole to fix the pad on the lifting clamp.

[0008] Optionally, the bottom surface of the square groove is provided with an anti-slip pad.

[0009] Optionally, a steel cable tie parallel to the bottom surface of the connecting box is connected to the side of the first connecting rod near the second connecting rod, and the outer end of the steel cable tie is inserted into and passes through the second connecting rod.

[0010] Optionally, a connecting plate located at the top of the steel cable tie is connected to the outer side of the second connecting rod. A threaded post is threadedly connected to the connecting plate, and a meshing tooth is connected to the bottom end of the threaded post. Steel teeth are provided on the surface of the steel cable tie, and the meshing tooth meshes with the steel teeth and restricts the unidirectional movement of the steel teeth.

[0011] This utility model discloses a steel lifting device that connects a first connecting rod and a second connecting rod via a lifting ring. During lifting, the lifting ring drives the connecting shaft to move upward along the slide groove, thereby moving the first and second connecting rods upward. The side wall of the connecting box restricts the first and second connecting rods, causing the two lifting clamps to approach and close together, thus fixing and lifting the steel material fixed in the groove above the lifting clamps. The thickness of the steel material held in the square groove of the lifting clamp is adjusted by the cooperation of bolts and washers to meet the clamping requirements of steel materials of different thicknesses. Furthermore, the cooperation of steel straps and interlocking teeth further improves the stability of the connection between the first and second connecting rods, making the lifting process safer.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Please see Figure 1 This utility model provides a steel hoisting device, including a connecting box 1. Vertical grooves 11 are provided on both opposite sides of the connecting box 1. A connecting shaft 12 is provided inside the connecting box 1, with both ends of the connecting shaft 12 passing through the two grooves 11 respectively. The width of both ends of the connecting shaft 12 is greater than the width of the grooves 11. A lifting ring 2 is rotatably connected to the surface of the connecting shaft 12. A first connecting rod 3 and a second connecting rod 5 are rotatably connected to the bottom of the lifting ring 2 respectively. The top ends of the first connecting rod 3 and the second connecting rod 5 are both located inside the connecting box 1. A hoisting clamp 4 is connected to the bottom end of the first connecting rod 3 and the bottom end of the second connecting box 5. A square groove 41 for placing steel is provided inside the hoisting clamp 4, and the square grooves 41 on the two hoisting clamps 4 are arranged opposite each other.

[0033] In this embodiment, when steel needs to be hoisted, the steel is placed in two opposing square slots 41 within two hoisting clamps 4. Then, the crane hook is attached to the lifting ring 2, and the hook pulls the lifting ring 2 upward. The lifting ring 2 drives the connecting shaft 12 to slide upward along the slide groove 11. Since the first connecting rod 3 and the second connecting rod 5 are rotatably connected to the connecting shaft 12, the first connecting rod 3 and the second connecting rod 5 move upward. The blocking effect on both sides of the connecting box 1 limits the first connecting rod 3 and the second connecting rod 5, so that the first connecting rod 3 and the second connecting rod 5 move closer to each other and close together, so that the steel can be fixed inside the two opposing square slots 41 by the two hoisting clamps 4, thereby completing the fixation of the steel and facilitating stable hoisting of the steel.

[0034] Furthermore, the bottom surface of the square groove 41 is provided with an anti-slip pad 42, which plays an anti-slip role for the steel and prevents the steel from slipping.

[0035] In some embodiments, the bottom end of the lifting clamp 4 is connected to a plurality of bolts 44, the top end of the bolts 44 penetrates the lifting clamp 4 and is inserted into the square groove 41, and a pad 45 is provided at the bottom end of the square groove 41. The surface of the pad 45 is provided with a threaded through hole 43 that matches the bolts 44. The bolts 44 are screwed into the threaded through hole 43 to fix the pad 45 on the lifting clamp 4.

[0036] In this embodiment, by setting bolt 44 and pad 45, the height of pad 45 can be adjusted by rotating bolt 44, thereby adjusting the depth of square groove 41, which makes it easy to fix steel of different thicknesses inside square groove 41.

[0037] In some other embodiments, a steel cable tie 32 parallel to the bottom surface of the connecting box 1 is connected to the side of the first connecting rod 3 near the second connecting rod 5. The outer end of the steel cable tie 32 is inserted into and passes through the second connecting rod 5. A connecting plate 31 located at the top of the steel cable tie 32 is connected to the outer side of the second connecting rod 5. A threaded post 33 is threadedly connected to the connecting plate 31. A meshing tooth 331 is connected to the bottom end of the threaded post 33. The surface of the steel cable tie 32 is provided with steel teeth 321. The meshing tooth 331 engages with the steel teeth 321 and restricts the unidirectional movement of the steel teeth 321. After the meshing tooth 331 engages with the steel teeth 321, the unidirectional movement direction of the steel teeth 321 is towards the direction away from the first connecting rod 3.

[0038] In this embodiment, by setting up steel cable ties 32 and threaded posts 33, the meshing teeth 331 at the bottom of the threaded posts 33 mesh with the steel teeth 321 on the surface of the steel cable ties 32, and the meshing teeth 331 can restrict the unidirectional movement of the steel teeth 321. This means that the steel cable ties 32 can only move in the direction away from the first connecting rod 3, so that the length of the steel cable ties 32 located between the first connecting rod 3 and the second connecting rod 5 can only shorten and cannot lengthen during the hoisting process. This ensures that the first connecting rod 3 and the second connecting rod 5 are always in a stable state during the hoisting process, thereby effectively improving the stability and safety of the entire hoisting process.

[0039] This utility model discloses a steel lifting device that connects a first connecting rod and a second connecting rod via a lifting ring. During lifting, the lifting ring drives the connecting shaft to move upward along the slide groove, thereby moving the first and second connecting rods upward. The side wall of the connecting box restricts the first and second connecting rods, causing the two lifting clamps to approach and close together, thus fixing and lifting the steel material fixed in the groove above the lifting clamps. The thickness of the steel material held in the square groove of the lifting clamp is adjusted by the cooperation of bolts and washers to meet the clamping requirements of steel materials of different thicknesses. Furthermore, the cooperation of steel straps and interlocking teeth further improves the stability of the connection between the first and second connecting rods, making the lifting process safer.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
