Shark pincers with emergent release function

Abstract

The invention relates to shark pincers with an emergent release function, belonging to the field of towing equipment for a ship. The shark pincers provided by the invention comprise a shark pincers executing system, a hydraulic master control system, a dynamical system and an emergent release device, wherein an oil outlet pipe of the power system is provided with a master oil-way check valve; and the emergent release device is connected in parallel to the oil outlet pipe between the master oil-way check valve and the hydraulic master control system. When the shark pincers normally work, the power system supplies oil to an energy accumulator of the emergent release device, so that a sufficient amount of high-pressure oil is accumulated in the energy accumulator. When the power source of the shark pincers fails, the high-pressure oil in the energy accumulator flows back to the hydraulic master control system to supply a power source to the hydraulic master control system, thereby finishing the emergent release of the shark pincers. The shark pincers provided by the invention have the advantages of simple structure and obvious economic benefit and are convenient to operate and control.

Description

technical field [0001] The invention relates to a shark pliers, in particular to a shark pliers with an emergency release function, belonging to the field of marine equipment. Background technique [0002] Shark clamp is a kind of equipment widely used in various ships. It is composed of shark clamp actuator, hydraulic main control system and power system. Its function is to hold the anchor chain or cable tightly when the ship is docked to prevent the anchor chain or cable from slipping . Invention patent application "equipment for shark jaws" (application number: 200782230496.5, application date: 2007.8.16, publication date: 2009.8.12) discloses a device for shark jaws on ships, which is arranged in the form of a shark Measuring device of one or more load readers on one or more sides of the jaws to read the strains of said anchor cables, cables, chains, etc. time stress situation. However, this patent application does not mention how to solve the technical problem of the...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the lack of emergency release function of the existing shark jaw device. In the emergency situation of power source failure, the defect and deficiency that the anchor chain or cable cannot be loosened, and provide a shark jaw with emergency release function. In an emergency where the power source of the shark jaw fails, at least one power source for loosening the anchor chain or cable is provided to quickly and safely realize the emergency release of the shark jaw, thereby ensuring the safety and reliability of the ship's operation
