Description

Technical Field

[0001] The utility model relates to the technical field of spraying and hoisting frames for guard plates, and particularly relates to a spraying and hoisting frame for a lower guard plate. Background Technique

[0002] Through a reasonably designed structure and mechanism, the spraying and hoisting frame for the lower guard plate enables the lower guard plate to remain stable during the spraying process, reducing problems such as uneven spraying and poor coating quality caused by shaking or sliding. At the same time, the hoisting frame can conveniently adjust the position of the lower guard plate, making the spraying operation more flexible and efficient.

[0003] As described in a spraying and hoisting device for preventing deflection (authorized announcement number: CN 218048540U) disclosed on the patent network, "A spraying and hoisting device for preventing deflection includes a top column and a hanging component. The top column includes a hanging column, a hanging plate is fixed at the lower end of the hanging column, a hanging ring is provided on the bottom surface of the hanging plate, and the hanging ring has a semi-circular structure; the hanging component includes a hook, and the hook is formed by bending a rectangular plate-shaped metal plate into a flat-mouth hook, and is provided with a hook part and a connecting part."

[0004] Regarding the above description, the applicant believes there are the following problems:

[0005] During the use of this utility model, the workpiece can be placed between the hanging rods, and the workpiece is hung by the upper hanging rod, or the workpiece is hung by both the upper hanging rod and the lower hanging rod to ensure that the workpiece does not rotate. However, in actual use, due to the fixed distance between the hanging rods, and when facing workpieces of different sizes, shapes or weights, the fixed distance between the hanging rods may not be fully adaptable, resulting in the upper hanging rod and the lower hanging rod being unable to hang the workpiece simultaneously. This may lead to instability during the hoisting process and may even damage the lower guard plate or the hoisting frame itself. Additionally, since the length of the hanging rod is fixed and the spraying position of the workpiece on the hook cannot be adjusted according to requirements, the application range of the hoisting frame is limited. Therefore, a spraying and hoisting frame for a lower guard plate needs to be improved. Content of the Utility Model
