[0026] Please refer to Figures 1-5 As shown, the present utility model is a lifting sling for machining a transmission shaft, including a suspension seat 1. A suspension rod 2 is fixedly connected to the top of the suspension seat 1. A plurality of clamping rods 118 are arranged on the front and back surfaces of the suspension seat 1. A lifting assembly 11 is arranged on the top of the suspension seat 1. A fixing assembly 22 is arranged inside the suspension seat 1. The number of the lifting assemblies 11 is two, and the parts included in the two lifting assemblies 11 are the same. The lifting assembly 11 includes a first fixing block 111. The bottom of the first fixing block 111 is fixedly connected to the top of the suspension seat 1. An electric push rod 112 is rotatably connected to the inner wall of the first fixing block 111.

[0027] The front output end of the electric push rod 112 is fixedly connected to a telescopic rod 113. The telescopic rod 113 is rotatably connected to a second fixing block 114. The front of the second fixing block 114 is fixedly connected to a connecting plate 115. The front of the suspension seat 1 is fixedly connected to a connecting block 116.

[0028] The number of the connecting blocks 116 is two. A rotating frame 117 is rotatably connected to the inner walls of the two connecting blocks 116. The top of the rotating frame 117 is fixedly connected to the bottom of the connecting plate 115. The bottom of the rotating frame 117 is fixedly connected to the tops of a plurality of clamping rods 118. By setting the lifting assembly 11, specifically, when the two electric push rods 112 are opened to drive the telescopic rod 113 to contract backward, the clamping rods 118 on the front and back surfaces can be separated and opened. When the device is lowered by a crane to a position where it can be clamped, the telescopic rod 113 is driven to extend forward to clamp the transmission shaft, so that the staff does not need to carry the transmission shaft manually, reducing the workload of the staff, improving the efficiency of transporting the transmission shaft, and avoiding the situation that the appearance quality is reduced due to collision during manual handling of the transmission shaft.

[0029] The number of the fixing components 22 is two. The two fixing components 22 are symmetrically arranged with the hanging rod 2 as the center. The parts included inside the two fixing components 22 are the same. The fixing component 22 includes a threaded rod 221. A circular groove one is formed inside the hanging seat 1, and the inner wall of the circular groove one is rotatably connected to the outer surface of the threaded rod 221.

[0030] A rotating handle 222 is fixedly connected to the top of the threaded rod 221. A circular groove two is formed at the bottom of the hanging seat 1, and an outer box 223 is fixedly connected to the inner wall of the circular groove two. The inner wall of the outer box 223 is rotatably connected to the outer surface of the threaded rod 221. A moving block 224 is threadedly connected to the outer surface of the threaded rod 221.

[0031] A groove one is formed inside the outer box 223. The number of the groove one is two, and the inner walls of the two groove ones are both slidably connected to the outer surface of the moving block 224.

[0032] A connecting rod 225 is fixedly connected to the bottom of the moving block 224. The number of the connecting rods 225 is two, and a limiting plate 226 is fixedly connected to the bottoms of the two connecting rods 225. By setting the fixing component 22, specifically, after the transmission shaft is clamped, the rotating handle 222 is rotated clockwise to drive the threaded rod 221 to rotate, so that the bottom of the limiting plate 226 contacts the outer surface of the transmission shaft to increase the friction force received by the transmission shaft during clamping, so that the transmission shaft will not fall during the hoisting process, making the hoisting of the transmission shaft safer and improving the practicability of the device.

[0033] A specific application of this embodiment is as follows: When the staff needs to carry the transmission shaft, the device is moved above the transmission shaft to be carried by a crane. Then, the two electric push rods 112 are opened to drive the telescopic rods 113 to contract backward. While the telescopic rods 113 contract, they will drive the connecting plate 115 to rotate towards the side close to the electric push rods 112. When the connecting plate 115 rotates, it will drive the rotating frame 117 to rotate within the inner walls of the two connecting blocks 116. During the rotation of the rotating frame 117, several clamping rods 118 will be driven to rotate, enabling the clamping rods 118 on the front and back to separate and open. When the device is lowered by the crane to a position where it can clamp, the two electric push rods 112 are used to drive the telescopic rods 113 to extend forward, causing the clamping rods 118 on both sides to rotate towards each other and clamp the transmission shaft. This enables the staff to avoid manually carrying the transmission shaft, reducing the workload of the staff, improving the efficiency of carrying the transmission shaft, and preventing the situation where the appearance quality is reduced due to the transmission shaft being knocked and rotated during manual handling. After the transmission shaft is clamped, the knob 222 is rotated clockwise to drive the threaded rod 221 to rotate. While the threaded rod 221 rotates, the moving block 224 threaded on its surface moves downward within the inner wall of the chute opened in the outer box 223. While the moving block 224 moves downward, it drives the two connecting rods 225 to move downward. During the downward movement of the connecting rods 225, the limiting plate 226 is driven to move downward, causing the bottom of the limiting plate 226 to contact the outer surface of the transmission shaft, increasing the friction force on the transmission shaft during clamping, preventing the transmission shaft from falling during hoisting, making the hoisting of the transmission shaft safer, and improving the practicality of the device.
