For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example:

[0025] like Figure 1 , Figure 2 and Figure 3 As shown: a half-axle shot blasting placement rack is provided with a shot blasting machine 1, a half-axle placement frame 2 and a suspended rotating hook body 3. The half-axle placement frame 2 includes a placement chassis 21, an intermediate stabilizing disc 22 and a central supporting suspension shaft 23. The placement chassis 21 and the intermediate stabilizing disc 22 are respectively arranged at the bottom and the middle of the central supporting suspension shaft 23, and a lifting ring 24 is also arranged on the top of the central supporting suspension shaft 23. The suspended rotating hook body 3 is provided with a hook structure 31 and a rotating drive disk structure 32. The top of the hook structure 31 is fixedly connected to the rotating center of the rotating drive disk structure 32. The lifting ring 24 cooperates with the hook structure 31, and the rotating drive disk structure 32 is separated from the half-axle placement frame 2, which can prevent the rotating drive disk structure 32 from blocking the placement position of the half-axle. A driving device 4 is installed on the top of the shot blasting machine 1 for driving the rotating drive disk structure 32 to rotate. A lifting slot is arranged on the top of the shot blasting machine 1, and the hook structure 31 passes through the lifting slot, and the driving device 4 is arranged on the side of the lifting slot.

[0026] A crane is also connected to the top of the rotating drive disk structure 32. The output end of the crane is fixedly connected to the top of the rotating drive disk structure 32 via a rotating shaft structure 7 or detachably connected via a hook. Fixed connection is preferred.

[0027] The above-mentioned driving device 4 is provided with a driving motor 41 and a gear driving member 42. The gear driving member 42 is connected to the output end of the driving motor 41. The suspended rotating hook body 3 is a gear disk, and the gear driving member 42 is meshed with the gear disk. The suspended rotating hook body 3 can also be a transmission disc, and the gear driving member 42 is also changed to a disc structure accordingly. The two realize transmission by frictional contact, which is easier to realize transmission coordination, but its transmission efficiency is not high and it is easy to slip.

[0028] Furthermore, a thrust bearing disc structure 5 is provided at the bottom of the suspended rotating hook body 3 , and the thrust bearing disc structure 5 is in contact with the top support of the shot blasting machine 1 .

[0029] Furthermore, a rotating placement plate 6 is also provided on the top of the shot blasting machine 1, and the suspended rotating hook body 3 is placed on the rotating placement plate 6; the rotating placement plate 6 has the same function as the thrust bearing plate structure 5, both of which are to avoid direct friction between the suspended rotating hook body 3 and the top of the shot blasting machine 1 during rotation, and then the resistance coefficient is large, so one of the settings can be selected, or both can be set.

[0030] Placement circular holes 25 are evenly arranged around the placement chassis 21 and the middle stabilizing disc 22, and can be arranged as square holes or spacer bars. Multiple placement circular holes 25 arranged in a ring are staggered. A support bar structure 26 is also welded at the bottom of the placement chassis 21, and the support bar structure 26 passes horizontally through the middle part below each corresponding placement circular hole 25. Among them, the support bar structure 26 is in a ring shape, which is convenient for overall welding. The side wall of the placement circular hole 25 is triangular prism-shaped, so that the contact surface is smaller.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention shall be defined by the appended claims.
