Description

Heavy-duty crane of phosphating surface treatment equipment

Technical Field

The utility model relates to the technical field of electroplating equipment, in particular to a heavy-duty crane of phosphating surface treatment equipment.

Background

The electroplating crane is a lifting device which is manufactured for improving the working efficiency, promoting the production automation and reducing the labor intensity. The electroplating travelling crane consists of a vertical arm, a travelling box, a transverse pull rod, a lifting arm and a water receiving disc. The lifting boom of the electroplating crane determines whether the load of the workpiece is stable or not. During operation, whether shaking exists or not.

If the center of gravity and the mass center of the product are not at the center point of the lifting arm, the workpiece can deviate from the right center of the V seat when falling down the V seat of the groove body. The secondary lifting is unstable and easily separated from the center point of the lifting hook. Therefore, the lifting of the suspension arm can be assisted by the design of the material frame, so that the phenomenon that the product workpiece is severely rocked due to direct contact between the suspension arm and the workpiece is avoided. However, the hook assembly on the existing material frame is usually formed by welding square tubes, so that the hook is in contact with a plane at the moment of contact of the hook assembly, and further the material frame is caused to shake.

Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-4, an embodiment of the present utility model is provided: the heavy-duty crane for phosphating surface treatment equipment comprises a portal frame 1 and a lifting hook 2 arranged on the portal frame 1, wherein the lifting hook 2 is hooked on a material frame 3 arranged on the crane to drive the material frame 3 to slide on the portal frame 1; the two sides of the material frame 3 are provided with hook assemblies 30, and the hook assemblies 30 comprise supporting shafts 34 connected with the lifting hooks 2; the supporting shaft 34 is cylindrical, and a hook body of the lifting hook 2 is provided with a hook groove matched with the supporting shaft 34; the supporting shaft 34 is connected with the material frame 3 through a column 31, and lifting lugs 33 are arranged on two sides of the column 31; one end of the lifting lug 33, which is far away from the upright post 31, is provided with a round hole 36 for installing the supporting shaft 34, and one end of the lifting lug 33, which faces the upright post 31, is movably installed on the upright post 31.

In summary, when the hook slot of the hook 2 is connected with the cylindrical supporting shaft 34, the cylindrical supporting shaft 34 can rotate in the round hole 36 of the lifting lug 33 and also can rotate in the hook slot of the hook 2, and the existing plane-to-plane contact is replaced by the arc surface to be contacted with the arc surface, so that the impact force of the moment of contact of the hook 2 with the material frame 3 can be buffered and the vibration phenomenon of the material frame 3 in moving can be relieved by utilizing the rotation of the supporting shaft 34.
