[0028] See also Figure 1 and Figure 3 A workpiece lifting mechanism for a suspended shot blasting machine includes a frame 1, two guide rails 2, two sets of lifting components 3, a limiting part 4 and a driving part 5.

[0029] The frame 1 is designed to be mounted on top of a hanging shot blasting machine, with part of it positioned directly above the machine and part extending outward from the machine's inlet. The portion of the frame 1 that corresponds to the machine's working area 1a is designated, while the portion extending outside the machine is designated as the loading and unloading area 1b.

[0030] The tracks of the two guide rails 2 are on a horizontal plane, that is, the two sets of hanging components 3 that subsequently slide on the guide rails 2 slide along the guide rails 2 in a horizontal plane.

[0031] Both guide rails 2 are fixedly connected to the frame 1. Each guide rail 2 comprises a straight segment 2a and an arc segment 2b. The straight segment 2a passes through the middle of the working area 1a, while the arc segment 2b reaches the loading and unloading area 1b. The closer the guide rails 2 are to the loading and unloading area 1b, the larger the distance between the two arc segments 2b. More specifically, the two guide rails 2 can be mirror-image symmetrical about a vertical plane.

[0032] The two sets of hoisting assemblies 3 are respectively arranged on the two guide rails 2, that is, the two sets of hoisting assemblies 3 slide along the two guide rails 2. During use, the two sets of hoisting assemblies 3, one of which is located in the straight section 2a, corresponding to the working area 1a, and operates within the hanging shot blasting machine, and the other set is located in the arc section 2b, corresponding to the loading and unloading area 1b, and loads materials within the hanging shot blasting machine. After the hanging shot blasting machine is completed, the hoisting assemblies 3 in the hanging shot blasting machine are first moved to the loading and unloading area 1b, and then the hoisting assemblies 3 in the loading and unloading area 1b are moved to the processing area and enter the hanging shot blasting machine, thus exchanging the positions of the two hoisting assemblies 3.

[0033] See also Figure 1 and Figure 2 A set of lifting components 3 includes a mounting portion 3a, a winch 3b, a lifting portion 3c, a hook 3d and a lifting frame 3e.

[0037] The winch 3b is installed on the mounting portion 3a. More specifically, the winch 3b can be installed on the horizontal portion of the mounting portion 3a.

[0038] The hoisting portion 3c is raised and lowered by the winch 3b. More specifically, the wire rope in the unwinding drum of the winch 3b can be a movable pulley passing through the hoisting portion 3c and then fixedly connected to the housing of the winch 3b or the mounting portion 3a.

[0039] The hook 3d is connected to the hanging portion 3c so as to rotate around a vertical axis.

[0040] The hanging frame 3e is used for placing workpieces and is connected to the hook 3d. That is, there is a hanging hole for the hook 3d to pass through on the top of the hanging frame 3e. The hanging frame 3e and the hook 3d rotate together relative to the hanging part 3c.

[0041] See also Figure 4 In some embodiments, the hanging frame 3e includes a connecting rod 3e1 for connecting the hook 3d and multiple layers of placement frames 3e2 fixedly connected to the connecting rod 3e1 from top to bottom.

More specifically, the mounting bracket body 3e2 can be provided with a hole for the connecting rod 3e1 to pass through, and the hole can be threaded with a bolt that can lock the mounting bracket body 3e2 to the connecting rod 3e1.

[0043] The number of the placement racks 3e2 on the connecting rod 3e1 and the distance between two adjacent placement racks 3e2 can be adjusted to better adapt to different workpieces for placement.

[0044] In some implementations, based on the above-mentioned embodiment of the hanging frame 3e, a plurality of hanging rods 3e2a are placed on the outer edge of the frame body 3e2.

[0045] Workpieces with holes can be hung on the hanging rod 3e2a.
