Description

Technical Field

[0001] This utility model relates to the field of iron outfitting loading and unloading technology, and in particular to an iron outfitting loading and unloading clamp. Background Technology

[0002] Iron outfitting components specifically refer to functional parts made of metal materials (such as steel, cast iron, aluminum alloys, etc.) used in outfitting, mainly for the navigation, operation, safety, and living needs of ships. Iron outfitting components are diverse, including anchors, anchor chains, doors and windows, handrails, masts, antenna supports, railings, pipe supports, etc.

[0003] In existing technologies, clamps are used to hold iron outfitting components during outfitting work. However, due to the wide variety of iron outfitting components, when loading and unloading long components such as masts, the clamps are generally placed at the center of gravity of the component. While this can hold and lift the component, its ends are difficult to restrain, have a high degree of freedom, and may rotate, affecting the stability of the clamping. Therefore, an improved iron outfitting component loading and unloading clamp is proposed. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a jig for loading and unloading iron outfitting parts, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a steel outfitting loading and unloading clamp, including a fixed frame, a drive box fixedly connected to the top of the fixed frame, a drive shaft rotatably connected inside the drive box, multiple push rods fixedly connected to both sides of the drive box, a driven shaft rotatably connected inside the drive box that can drive the multiple push rods to extend and retract, a transmission gear set provided between the drive shaft and the driven shaft, and a movable frame fixedly connected to the ends of the multiple push rods; a multi-stage telescopic rod provided between the movable frame and the fixed frame, two clamping plates provided in both the fixed frame and the movable frame, and a drive assembly provided in the movable frame that can drive the clamping plates to perform clamping actions.

[0007] Preferably, in any of the above solutions, both the fixed frame and the movable frame adopt a U-shaped structure, and both the fixed frame and the movable frame are provided with a lifting ring at the top.

[0008] The above technical solution provides installation space for both the fixed frame and the movable frame, with the fixed frame also serving as an installation platform for the drive box.

[0009] Preferably, in any of the above solutions, the drive box is located at the middle position on the top surface of the fixed frame, and a handwheel is provided at the outer end of the drive shaft.

[0010] The above technical solution employs a drive box that provides a mounting platform for the drive shaft and driven shaft. The drive box is positioned at the center of the top surface of the fixed frame, and, in conjunction with multi-stage push rods, provides stable support for the moving frame. The drive shaft drives the driven shaft to rotate, allowing adjustment of the length of the multi-stage push rods.
