Description

Technical Field

[0001] This utility model relates to a safe and convenient lifting tool, belonging to the technical field of lifting accessories. Background Technology

[0002] When lifting bulk I-beams, a common method is to directly tie the I-beams with wire ropes. However, using wire ropes during the lifting process can easily cause the I-beams to become uneven, shifting their center of gravity and slipping, leading to accidents and safety issues. Another method is to drill holes in the upper flange of the I-beam to connect the lifting ropes, or to weld lifting lugs onto the upper flange of the steel pipe pile. However, this can damage the I-beams.

[0003] Although there are various special lifting tools for I-beams on the market, they are relatively complex in structure, have high cost, and poor versatility, and can only be used for lifting I-beams.

[0004] To address the aforementioned problems, this application proposes a safe and convenient lifting device. Utility Model Content

[0028] Example

[0029] like Figures 1-7 As shown, the device includes a workpiece 4 to be hoisted and a hoisting connector 2. The workpiece 4 to be hoisted comprises two vertically arranged vertical plates and a horizontal plate, with the horizontal plate fixedly disposed between the vertical plates. Specifically, the workpiece 4 to be hoisted can be an I-beam as described in the background art, or a C-shaped steel or a U-shaped steel. A hoisting clamp 3 is provided at the bottom of the hoisting connector 2. The hoisting clamp 3 is composed of a clamping connector 31, an upper clamping part 32, and a lower clamping part 33. The upper clamping part 32 and the lower clamping part 33 are arranged parallel to each other on the clamping connector 31. The distance between the upper clamping part 32 and the lower clamping part 33 is slightly greater than the thickness of the horizontal plate. During hoisting, the clamping clamp is positioned such that the workpiece 4 is a vertically arranged vertical plate and a horizontal plate is a horizontal plate. The upper clamping part 32 and the lower clamping part 33 form a clamping mechanism with the workpiece 4 to be lifted, thereby achieving safe and stable lifting. In use, the lifting clamp 3 clamps the workpiece 4 from both ends onto the horizontal plate, while the upper clamping part 32 and / or the lower clamping part 33 are located between the vertical plates. When the workpiece 4 to be lifted is lifted by a crane or other lifting machinery, the crane or other lifting machinery is connected from the top through the lifting connector 2, and the lifting clamp 3 is hooked to the bottom of the lifting connector 2. When the lifting clamp 3 moves upward, the upper clamping part 32 and the lower clamping part 33 form a clamping mechanism with the workpiece 4 to be lifted, thereby stably and safely lifting the workpiece 4 to be lifted.

[0030] In some alternative embodiments, the lifting connector 2 is provided as a lifting strap or chain.

[0031] In some alternative embodiments, the clamping connector 31 is configured as a ring or a plate.

[0032] Specifically, the upper clamping part 32 is configured as a first upper clamping plate 321, and the lower clamping part 33 is configured as a lower clamping plate 331. The first upper clamping plate 321 and the lower clamping plate 331 are fixedly connected in parallel to the clamping connector 31. When hoisting the I-beam, in the vertical direction, the first clamping plate 321 and the lower clamping plate 331 form a clamping structure with the horizontal plate of the I-beam. At the same time, the vertical plate blocks the first clamping plate 321 and the lower clamping plate 331 in the horizontal direction. Similarly, it can play the same role for other structural forms of the parts to be hoisted 4.

[0033] In some optional embodiments, the clamping connector 31 is configured as a plate structure, and the top of the clamping connector 31 is provided with a lifting hole 312 for connecting the lifting connector 2.

The adjusting base plate 322 and the lower clamping plate 331 are fixedly connected in parallel to the clamping connector 31. The second upper clamping plate 323 is arranged in parallel between the adjusting base plate 322 and the lower clamping plate 331 and is slidably connected to the clamping connector 31. The adjusting base plate 322 is threaded with an adjusting screw 35 for limiting the second upper clamping plate 323. Considering the different thicknesses of the parts to be lifted 4, the lifting fixture 3 is designed as an adjustable structure. In use, by rotating the adjusting screw 35, the adjusting base plate 322 is pressed against the horizontal plate of the part to be lifted 4, thereby adapting to different thicknesses of the parts to be lifted 4.

[0034] Furthermore, the adjustment base plate 322 is provided with a threaded hole 3221 that matches the adjustment screw 35. The adjustment screw 35 is set as a wing screw, which can be turned by hand, making the operation more convenient and quick.

[0035] In some alternative embodiments, the second upper clamping plate 323 is provided with a first slider 3231 near the clamping connector 31, and the clamping connector 31 is provided with a first groove 311 that matches the first slider 3231.

[0036] In some alternative embodiments, the second upper clamping plate 323 is provided with a second sliding groove 3232 at one end near the clamping connector 31, and the clamping connector 31 is provided with a second slider 313 that matches the second sliding groove 3232.

[0037] In addition, it includes a hook 1, one end of which is connected to a lifting connector 2, and the other end of which is connected to a crane or other lifting machinery via a lifting strap or chain. This allows for the selection of... Figure 1 The triangular structure shown can also be hoisted by setting two hooks 1 at both ends.
