[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0028] Example 1

[0029] like Figures 1 to 4 As shown, a hanger for workpiece cleaning includes a hanging mechanism and a hanger frame, the hanger frame includes a mounting plate 1, and the hanging mechanism includes two sets of hanging components relatively arranged on the mounting plate 1;

[0030] The hoisting assembly includes a hook 5 and a driving member 4. The hook 5 is connected to the mounting plate 1 by sliding fit. The driving member 4 is arranged on the mounting plate 1 and is used to drive the hook 5 to slide horizontally on the mounting plate 1 along the length direction of the mounting plate 1.

[0031] The hook 5 is L-shaped and the active end of the hook 5 passes through the mounting plate 1 and extends to the bottom of the mounting plate 1. The distance between the upper end surface of the active end of the hook 5 and the lower end surface of the mounting plate 1 matches the size of the boom 101 of the hanging frame 10. During lifting, the upper end surface of the boom 101 abuts against the lower end surface of the mounting plate 1 and the upper end surface of the active end of the hook 5 abuts against the lower end surface of the boom 101.

[0032] The sling drives the hook 5 to slide on the mounting plate 1 through the driving member 4, so that the hook 5 and the boom 101 can cooperate more easily; the hook 5 is L-shaped and matches the size of the boom 101 of the hanging frame 10, so that the hook 5 and the boom 101 fit perfectly, and the hanging of the hanging frame 10 is more stable and not easy to fall off; the sling has better integrity by setting a sling frame and setting the hanging mechanism in the sling frame; the sling has a simple structure, is easy to manufacture, and is more stable in grasping the hanging frame 10.

[0033] Example 2

[0034] like Figure 1 As shown, an inclined guide surface 9 is provided on the upper end surface of the working end of the hook 5 at the end position of the working end, and the guide surface 9 can facilitate the upper end surface of the working end of the hook 5 to abut against the lower end surface of the boom 101.

[0035] like Figure 1 , Figure 3 As shown, a positioning mechanism is provided on the working end of the hook 5, and the positioning mechanism cooperates with the corresponding fixing bolt 103 on the boom 101. By providing the fixing bolt 103, it is convenient to position the hook 5 on the boom 101, and it can also limit the hook 5 when the hook 5 acts on the boom 101, preventing the hook 5 from sliding left and right, which is helpful for the stability of the lifting.

[0036] Furthermore, if Figure 1 As shown, the positioning mechanism is a clearance groove 8.

[0037] In some embodiments, the sling frame further includes a buffer mechanism 7, which includes two buffer members arranged on the sling frame, and the buffer members are respectively arranged on the outer sides of the hook 5, and are used to provide a buffering force when the driving member 4 drives the hook 5 to move toward the boom direction to the hoisting position, so as to prevent the hook 5 from colliding with the boom of the hanging frame, thereby causing damage to the boom or the hook, and also to buffer the movement of the guide assembly 3, thereby preventing the guide assembly 3 from being damaged due to excessive movement. The buffer member can be an elastic member or a hydraulic buffer, etc.

[0038] Example 3

[0039] A guide mechanism is provided between the hook 5 and the mounting plate 1 , and the guide mechanism includes two sets of guide components 3 , and the fixed ends of the hook 5 are respectively provided on the two sets of guide components 3 , so that the hook 5 can slide horizontally on the mounting plate 1 along the length direction of the mounting plate 1 .

[0040] like Figure 1 As shown, the guide assembly 3 includes a slide rail 31 and a slider 32. The slide rail 31 is horizontally arranged on the mounting plate 1. The slider 32 is slidably arranged on the slide rail 31. The fixed end of the hook 5 is installed on the slider 32. The driving member 4 is fixed to the hook 5 and is used to drive the hook 5 and the slider 32 to slide on the slide rail 31.

[0041] In some embodiments, the guide components 3 are respectively located at both ends of the mounting plate 1, and the hooks 5 are arranged in cooperation with each group of guide components 3. The hooks of the hooks 5 are arranged in opposite directions. At this time, there are also two driving components 4, which respectively drive the hooks 5 and the sliders 32 to slide on the slide rails 31; when the sling is coordinated with the hanging frame 10, the hooks 5 are lowered to the boom 101, and opposite forces are applied to the hooks 5 through the driving components 4, so that the hooks 5 move in opposite directions, so that the upper end surface of the hooks 5 abuts against the lower end surface of the boom 101.

[0042] like Figure 4 As shown, a positioning column 6 that cooperates with the positioning hole 102 on the boom 101 is provided on the bottom wall of the mounting plate 1. When the sling grabs the hanging frame 10, it is only necessary to align the positioning column 6 with the positioning hole 102 on the boom 101 to place the hook 5 in the correct position. At this time, the driving member 4 drives the hook 5 to move in the opposite or relative direction, so that the upper end surface of the hook 5 abuts against the lower end surface of the boom 101, and then the sling firmly grasps the hanging frame 10, which is convenient for subsequent cleaning operations.

[0043] The sling frame also includes a connecting plate 2, which is fixedly connected to the mounting plate 1 to form a frame structure, and the connecting plate 2 is used to connect to an external driving device.

[0044] Example 4

[0045] The hoisting system comprises an external driving device and a hoisting device, wherein the external driving device is fixedly connected to a hoisting device frame.

[0046] The external driving device can slide on the guide rail, and the external driving device can make the hanger move up and down in the vertical direction, and cooperate with the guide rail so that the external driving device can drive the hanger to move left and right, so as to grab the hanging frame and move it above the cleaning machine, and then lower the hanging frame into the cleaning machine for cleaning operation.

[0047] In some embodiments, the external driving device is a lifting cylinder, and multiple lifting cylinders are provided and connected to the connecting plate 2 of the sling. Through the provision of the multiple lifting cylinders, the connection between the lifting cylinder and the sling is more stable and reliable, preventing shaking during the lifting process.

[0048] The working process of the lifting system is:

[0049] The external driving device drives the hanger to move to the top of the hanging frame 10, aligns the positioning column 6 with the positioning hole 102 on the hanging arm 101, and the external driving device drives the hanger to move downward and cooperates with the driving member 4 to clamp the hook 5 and the hanging arm 101; then the external driving device drives the hanger to lift and move along the guide rail to the top of the cleaning machine, and then drives the hanger downward by the external driving device to put the hanging frame 10 into the cleaning machine, and the workpiece in the hanging frame 10 is cleaned.
