A U-shaped frame 24 is fixed at the lower end of the steel chain 23. A fixing bolt 25 is threadedly connected to one side of the U-shaped frame 24.

[0025] Specifically, the hoisting assembly 2 also includes a fixing plate 212. The fixing plate 212 is fixed on the upper side inside the fixing cylinder 22. A second motor 213 is installed on the upper end of the fixing plate 212. A rotating plate 210 is provided at the output end of the second motor 213. A winch 211 is installed on the rotating plate 210. A protruding ring 214 is fixed on the side of the rotating plate 210. An annular groove 215 corresponding to the protruding ring 214 is opened inside the fixing cylinder 22.

[0026] By adopting the above technical solution, when performing shot blasting, motor 213 can be turned on to drive the rotating plate 210 to rotate. The rotation of the rotating plate 210 drives the winch 211 and the steel chain 23 to rotate, thereby driving the casting at the lower end of the steel chain 23 to rotate. This facilitates shot blasting and grinding of different positions of the casting, improving the efficiency of the shot blasting equipment. When the rotating plate 210 rotates, the convex ring 214 on the side of the rotating plate 210 rotates in the annular groove 215, making the rotation of the rotating plate 210 more stable.

[0027] Specifically, a protective cylinder 216 is fixed at the lower end of the fixed cylinder 22 at the position corresponding to the steel chain 23. The fixed cylinder 22 and the slider 28, as well as the protective cylinder 216 and the fixed cylinder 22, are all welded by spot welding.

[0028] By adopting the above technical solution, fixing the protective cylinder 216 at the lower end of the fixed cylinder 22 can protect the steel chain 23.

[0029] Specifically, the slider 28 has a threaded hole corresponding to the lead screw 27, and a bearing rotating seat is provided between the lead screw 27 and the strip box 21.

[0030] By adopting the above technical solution, the lead screw 27 can rotate in the strip box 21, and the rotation of the lead screw 27 can drive the slider 28 to move in the strip box 21.

[0031] In this embodiment, when using the hoisting shot blasting equipment for castings, the device is installed in a suitable position, the shot blasting nozzle 4 is connected to the shot blasting equipment, and the device is moved to the side of the heavy casting via rollers 5. The U-shaped frame 24 is then passed through the pre-drilled hole in the casting, and the fixing bolts 25 are screwed into the U-shaped frame 24 for limiting. The winch 211 rewinds the steel chain 23 to lift the casting. The motor 26 is turned on to drive the lead screw 27 to rotate. The rotation of the lead screw 27 causes the slider 28 to move in the groove 29 at the lower end of the strip box 21. The movement of the slider 28 causes the fixed cylinder 22 to move, thereby moving the casting into the shot blasting box 1. The box door 7 is closed, and the shot blasting equipment can then blast through the shot blasting nozzle 4. The hoisted castings are shot blasted. The hoisting assembly 2 facilitates shot blasting of heavy castings, improving the practicality of the device. During shot blasting, motor 213 can be turned on to rotate the rotating plate 210. The rotation of the rotating plate 210 drives the winch 211 and the steel chain 23 to rotate, thereby rotating the casting at the lower end of the steel chain 23. This facilitates shot blasting of different positions of the castings and improves the efficiency of the shot blasting equipment. When the rotating plate 210 rotates, the convex ring 214 on the side of the rotating plate 210 rotates in the annular groove 215, making the rotation of the rotating plate 210 more stable. The protective cylinder 216 fixed at the lower end of the fixed cylinder 22 can protect the steel chain 23.
