Abstract
An emergency release device for large-bore harbor loading arms comprises an upper valve body, a lower valve body and a splint assembly, wherein the splint assembly includes a fitting seat, a left splint, a right splint, a clamping ram and a nut; the upper and the lower valve bodies are an upper butterfly valve and a lower butterfly valve which are butted with each other; an upper flange connected with an oil loading arm is arranged on the upper side of the upper butterfly valve; a lower flange connected with a tank ship is arranged on the lower side of the lower butterfly valve; convex edges in fit with the left and the right splints are formed at the part where the two butterfly valves are butted; a hydraulic cylinder is fixedly mounted on the upper valve body; a push rod is connected with the lower end of a piston rod of the hydraulic cylinder; bosses are arranged on the inner side of the push rod to push tommy bars of the upper and the lower butterfly valves respectively; and an external boss is arranged on the outer side of the push rod to match with the clamping ram. When a loading arm detects an oil tanker out of a designed drifting range, the hydraulic cylinder is driven into motion and the left and the right splints are opened, so that the upper and the lower butterfly valves can be separated. The closed status of the upper and the lower butterfly valves before the separation avoids the overflow of mediums of the loading arm and the oil tanker, thereby guaranteeing the safety. The utility model has the advantages of small thickness and structural size as well as light weight.
Description
Technical field
The utility model relates to a kind of harbour handling tool, particularly a kind of heavy caliber harbour handling arm emergency separating device.
Background technology
Modern Shipbuilding is already for improving conveying efficiency, and to the development of mammoth tanker aspect, thereupon, the harbour handling ability also needs supporting raising, therefore, generally adopts heavy caliber harbour loading and unloading arm more than 12 inches.Along with implementing of national environmental protection policy and safety policy, heavy caliber loading and unloading arm also needs to install emergency separating device, to satisfy the needs of safety, environmental protection.At present, the emergency separating device scantling of structure on the market is big, and Heavy Weight makes the overall weight of loading and unloading arm increase a lot, comparatively is applicable to the loading and unloading arm below 8 inches that bore is little.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed little, the lightweight heavy caliber harbour handling of a kind of scantling of structure arm emergency separating device.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of heavy caliber harbour handling arm emergency separating device, comprise, following valve body and cleat assembly, cleat assembly comprises mount pad, left and right sides clamping plate, clamp connecting rod and nut, be characterized in: on, following valve body be mutually butt joint on, following two dish valves, be provided with the upper flange that links to each other with oil transfer arm above the last dish valve, establish below the following dish valve and groove ship bonded assembly lower flange, two dish valve joints are provided with the convex edge that cooperates with left and right sides clamping plate, be fixed with the hydraulic actuating cylinder bearing on the upper valve body, hydraulic actuating cylinder vertically is housed on the hydraulic actuating cylinder bearing, the piston-rod lower end of hydraulic actuating cylinder is connected with push rod, the inboard of push rod is respectively equipped with in the promotion, the boss of following dish valve tommy bar is provided with in the outside of push rod and clamps the outer lug boss that connecting rod cooperates.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, is provided with connecting through hole on described flange, and corresponding dish valve is provided with threaded connection hole, is connected by screw between dish valve and its flange.
The technical problems to be solved in the utility model can also be come by the following technical programs further to realize, be clamped on the connecting rod safety pin is housed.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, coorespondingly between upper and lower two dish valves is provided with the breaker bolt unthreaded hole, and is connected to a fixed by breaker bolt.
Principle of work: emergency separating device is installed in the end of loading and unloading arm, after loading and unloading arm and oil tanker being connected, the breaker bolt on the disconnecting gear is taken off, hydraulic efficiency pressure system is in excited state, when detecting oil tanker, the loading and unloading arm surpasses design-calculated drift scope, provide the hydraulic valve signal, open hydraulic valve, make the hydraulic actuating cylinder action, the hydraulic actuating cylinder push rod promotes the butterfly valve tommy bar and moves downward, close simultaneously, promote immediately after closing to clamp connecting rod, cut off safety pin, the clamping connecting rod is downward, break away from clamped condition, open left and right sides clamping plate, owing to be subjected to the push-and-pull of oil tanker, following butterfly valve skids off from clamping plate, following butterfly valve is taken away by oil tanker, and last butterfly valve breaks away from oil tanker with the lifting of loading and unloading arm.Because butterfly valve is all to cut out up and down before throwing off, medium, the oil tanker medium of guaranteeing to load and unload arm can be not excessive, guaranteed safety.After handling accident, will descend butterfly valve to take off again, be installed on the loading and unloading arm, it is in a safe condition, prepare for using next time from oil tanker.Emergency separating device two video discs on the loading and unloading arm are to be in opening.
The utility model compared with prior art owing to adopt purpose made to the folder butterfly valve structure, thin thickness, scantling of structure are little, therefore in light weight; Has fire-proof function:, during baked wheaten cake, still have closing function when because the scene is on fire; Can be according to API607, experiment overdoes; By the design of safety pin and breaker bolt, make this device that the safety guard of mode of operation and off working state arranged.
