Embodiment Construction

[0043] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0044] In an embodiment of the present disclosure, the shark jaw includes a link type shark jaw. Figure 1-Figure 3 It is a three-view diagram of the link type shark jaw provided by the embodiment of the present disclosure. see Figure 1-Figure 3 , The shark jaw includes a casing 81, a nipper assembly and a top pin 83. The nipper assembly includes two nippers 82 that can be flipped and stretched independently. During work, the anchor chain or steel cable is fixed between the two nippers 82; when not in use, the two nippers 82 fall back to the box 81 Inside and flush with the top of the casing 81. The jacking pin 83 is located between the two nippers 82 , and can lift the drooping anchor chain or steel cable between the two nippers...

Abstract

The invention provides a loading test device for shark pincers, and belongs to the technical field of ship engineering. The loading test device comprises a hydraulic cylinder assembly, a lever mechanism and a tension transmission mechanism. The lever mechanism comprises a base, a lever and a supporting pin. The lever is arranged on the base in the mode that the lever can rotate on the horizontal plane with the supporting pin as the fulcrum. The distance between the supporting pin and the first end of the lever is larger than the distance between the supporting pin and the second end of the lever. The hydraulic cylinder assembly and the tension transmission structure are arranged at the two ends of the lever respectively. The hydraulic cylinder assembly is connected with the first end of the lever, the tension transmission mechanism is arranged between the lever mechanism and the shark pincers to be tested, and the tension transmission mechanism is respectively connected with the secondend of the lever and the shark pincers to be tested.

Description

technical field [0001] The disclosure relates to the technical field of ship engineering, in particular to a loading test device for shark jaws. Background technique [0002] The main function of the shark clamp is to hold the anchor chain or wire rope tightly to prevent the anchor chain or wire rope from slipping. Whether the performance of the shark pliers meets the requirements of use needs to be verified by loading tests to ensure the safety of the actual ship. [0003] In the related art, the loading test method of the shark jaw adopts oil cylinder pulling or winch pulling. During the test, one end of the anchor chain or wire rope is connected to the winch or oil cylinder, and the other end is connected to the shark jaw. The load of the jaws is measured by tightening the wire rope or anchor chain by winches or cylinders to load the jaws. [0004] Using oil cylinders or winches to pull each other, for the load of large-tonnage shark jaws, the size of the oil cylinder ...
