DETAILED DESCRIPTION

[0025] The utility model will be further explained in combination with the drawings and examples, and the mode of the utility model includes but is not limited to the following examples. EMBODIMENT

[0026] As Figures 1-6 The utility model provides a round workpiece safety lifting appliance, including: support frame 1, two claws 2 are installed on support frame 1, and adjusting mechanism is equipped between the two claws 2, and the adjusting mechanism is used for adjusting the distance between the two claws 2, in this embodiment, the adjusting mechanism includes threaded tube 4, two screw rods 3 of opposite screw rotation are installed at the both ends of threaded tube 4, one end of screw rod 3 is rotatably connected with claw 2, and detachable lifting buckle 5 is installed on the top of support frame 1, inclined hole 11 is formed in support frame 1, guide rod 10 is slidably installed in inclined hole 11, and guide rod 10 is fixedly connected with claw 2. Figures 5-6 When using, as

[0027] By setting support frame 1 and two claws 2, and setting the adjusting mechanism capable of adjusting the distance between the two claws 2 between the two claws 2, and setting inclined hole 11 on support frame 1, when hoisting workpiece 17, the guide rod 10 is slid along inclined hole 11 by using the gravity of workpiece 17 itself, the claw 2 is rotated, the workpiece 17 is further clamped, the workpiece 17 is more safe when hoisting, and the use safety of the lifting appliance is improved. EMBODIMENT

[0028] As Figures 1-3As shown, a vertical hole 9 is provided on the support frame 1, and a connecting shaft 8 is slidably installed in the vertical hole 9. A support block 7 is movably installed in the support frame 1. The support block 7 is fixedly connected to the connecting shaft 8, and the support block 7 is connected to the lifting buckle 5 through a threaded pin 6. When in use, the threaded pin 6 can be unscrewed to easily disassemble the lifting buckle 5. The lifting buckle 5 can be connected to the lifting device through a wire rope. When the lifting buckle 5 is lifted, it rises, thereby pulling the support block 7 to rise. The rise of the support block 7 causes the connecting shaft 8 to slide and rise along the vertical hole 9.

[0029] By setting the threaded pin 6, the hanger 5 can be easily disassembled. By setting the support block 7, the connecting shaft 8 and the vertical hole 9, the hanger 5 can be easily connected to the support frame 1. Example

[0030] like Figures 1-3 As shown, a linkage plate 12 is installed between the support block 7 and the jaw 2. The two ends of the linkage plate 12 are hinged to the support block 7 and the jaw 2. When using the device, when lifting the workpiece 17, the support frame 1 is first lifted up, so that the guide rod 10 slides down along the inclined hole 11, so that the lower end of the jaw 2 moves closer and further clamps the workpiece 17. At the same time, the guide rod 10 slides down through the linkage plate 12, driving the support block 7 to rise. The lifting buckle 5 is then pulled up, so that the support block 7 continues to rise. When the support block 7 rises, a lateral force is applied to the guide rod 10 through the linkage plate 12, so that the guide rod 10 slides down along the inclined hole 11, thereby further increasing the clamping force of the jaw 2 on the workpiece 17, making the state of the workpiece 17 more stable and less likely to fall off the lifting device, thus improving the safety of the lifting device.

[0031] By installing a linkage plate 12 between the support block 7 and the jaw 2, the clamping force of the jaw 2 on the workpiece 17 can be increased by the linkage plate 12, which can further improve the safety of the lifting device. Example

[0032] like Figures 2-6 As shown, a limit frame 13 is installed on the inner side of the chuck 2. When in use, the limit frame 13 abuts against the top of the workpiece 17 to limit the top of the workpiece 17, making the state of the workpiece 17 more stable when clamped on the lifting device and less likely to fall off, thereby further improving the safety of the lifting device.

[0033] By installing a limiting bracket 13 on the inside of the chuck 2, the top position of the workpiece 17 can be limited, further improving the safety of the lifting device. Example

[0034] like Figure 4As shown, the limiting frame 14 is installed on the clamping jaw 2, a plurality of limiting holes 15 are uniformly arranged on the limiting frame 14, and the limiting pin 16 is detachably installed on the limiting frame 13. The limiting frame 13 is connected with the limiting frame 14 through the limiting pin 16. Specifically, the limiting pin 16 passes through the corresponding limiting hole 15 and the limiting frame 13, so that the limiting frame 13 is connected with the limiting frame 14. During use, according to the diameter of the workpiece 17, the limiting pin 16 is inserted into the corresponding limiting hole 15, and the height of the limiting frame 13 is adjusted to adapt to the hoisting of workpieces with different diameters.

[0035] By setting the limiting frame 14 and uniformly arranging a plurality of limiting holes 15 on the limiting frame 14, the limiting frame 13 is connected with the limiting frame 14 through the limiting pin 16, so that the relative height of the limiting frame 13 on the clamping jaw 2 can be conveniently adjusted to adapt to the hoisting of workpieces with different diameters.

[0036] Working principle: during use, the two clamping jaws 2 are erected on the circular workpiece 17, the threaded pipe 4 is rotated to make the two screw rods 3 close to each other, so that the clamping jaw 2 clamps the workpiece 17, the lifting tool is used to pull the lifting buckle 5, so that the support frame 1 is lifted, the support frame 1 is lifted, the guide rod 11 slides along the inclined hole 10, so that the distance between the top of the two clamping jaws 2 is increased, the two clamping jaws 2 rotate around the hinge shaft of the screw rod 3 and the clamping jaw 2, the lower ends of the two clamping jaws 2 are close to each other, so that the two clamping jaws 2 further clamp the workpiece 17, preventing the workpiece 17 from falling off, and the lifting tool is more safe during hoisting the workpiece.
