Abstract
The utility model provides an oil transfer arm rotary type emergency separation device and mainly consists of a swivel connection, a bipyramid valve, a blocking organization and a manual hydraulic control system. The model is characterized in that the rotary-type emergency separating connection is fixed at the vertical section of the three-way swivel connection at the end of the outer arm of the oil transfer arm(instead of the original swivel connection). The emergency separating connection consists of the bipyramid valve, a duel group rolling steel ball and the blocking organization. In case of the occurring of unexpected case, the ships and vehicle in the process of petroleum product loading or unloading can be ensured to leave the site immediately to avoid serious consequences. The device is applicable to the manual oil transfer arm and also the hydraulically powered oil transfer arm if the manual pump in the hydraulic system is changed to a motor pump.
Description
Affiliated technical field
The utility model relates to a kind of dock ship and vehicle loading and unloading oil product and the requisite specialized equipment of other chemical products, particularly a kind of rotary loading arm formula emergency release device.
Rotatable urgent separating joint and hand-hydraulic control system can be installed on the manual oil transfer arm, can guarantee loading and unloading boats and ships in the oil product, vehicle etc. and flee the scene rapidly when meeting accident dangerous situation, produce to avoid serious consequence.
Background technology
Oil transfer arm is to be used for harbour, dock ship and vehicle loading and unloading oil product and the requisite specialized equipment of other chemical products.Oil transfer arm can both be in normal working in the clear working place, but some emergency case are arranged also, drift out or the storm that happens suddenly etc. makes oil transfer arm exceed range of safety operation at trestle as anchor line breakdown, boats and ships, even break, cause leakage, accident dangerous situations such as fire occur.In recent years, the water transport traffic accident takes place frequently, and its major cause is that manual oil transfer arm does not cause boats and ships or vehicle etc. can not in time flee from the deficiency of the scene of the accident because of there being emergency separating device, gives country and people life property loss serious.Therefore, be badly in need of a kind of double-valve structure device that can ejection escape of development.Can guarantee the ejection escape of boats and ships etc. and oil transfer arm like this, close the two ends oil pipeline simultaneously, prevent that oil product is excessive, boats and ships etc. also can in time be fled the scene, and prevent fire spreading, set off an explosion, and jeopardize boats and ships, harbour, and personnel's life.
Have only a few developed countries such as American and Britain, method that this product is arranged abroad, China has a few enterprise (as Dalian Port Office, Lianyungang Ocean Fluid Loading-Unloading Equipment Co., Ltd.) to start to develop this product in late 1990s, but does not all succeed.
Summary of the invention
The purpose of this utility model is not cause boats and ships or vehicle etc. can not in time flee from the deficiency of the scene of the accident in order to overcome existing manual oil transfer arm because of there being emergency separating device, a kind of rotary loading arm formula emergency release device is provided, and it is integrated that swivel coupling and emergency release device have been realized.
The purpose of this utility model is achieved in that the urgent separating joint of swinging is loaded on vertical section (swivel coupling that replaces original position) of the terminal three-dimensional swivel coupling of oil transfer arm outer arm by two end flanges.Urgent separating joint is made of bipyramid valve, two groups of rolling steel balls and clamping body etc.It is characterized in that, pipe nipple links to each other with pipeline with interior ring, outer shroud and interior interannular are equipped with two groups of rolling steel balls, the bipyramid valve links to each other with retracing spring, and be fixed on the support, outer shroud is by clamping body locking, when the oil transfer arm normal running, outer shroud can rotate relatively around interior ring under the effect of two row rolling steel balls, realizes the function of swivel coupling.When emergency situation takes place when, operating personal is pulled the two-position four way change valve in the hydraulic efficiency pressure system, control presssure oil is switched, main inlet valve is opened, main fuel-return valve is closed, and pressure oil enters the oil cylinder of pulling pin, and bearing pin is extracted, clamping body moment takes off and separates, and two cone valves cut out the two ends pipeline under action of reset spring.Realization oil transfer arm pipeline separates fast with the boats and ships menifold, guarantees dock ship and personnel's safety.
The beneficial effects of the utility model are, when meeting accident dangerous situation, can guarantee loading and unloading boats and ships in the oil product, vehicle etc. and flee the scene rapidly, produce to avoid serious consequence.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Figure one is the utility model constructional drawing.
Figure two is the utility model clamping body constructionals drawing.
Figure three is lateral plans of figure two
Figure four is the utility model hand-hydraulic control system schematic diagrams.
The specific embodiment
By figure one as can be known, pipe nipple 1 links to each other with pipeline with interior ring 11.11 on outer shroud 5 and interior ring are equipped with two groups of rolling steel balls 9, and its effect is to connect inner and outer rings and the attached effect that helps rotation.Bipyramid valve 3 sets back under retracing spring 2 effects and cuts out the two ends pipeline, and 6 pairs of bipyramid valves 3 of support play fixing and directional tagging.Outer shroud is made up of two parts, and by clamping body 7 lockings.
By figure two-three as can be known, clamping body is by formations such as " V " shape fixture block 13, connecting rod 14, bearing pin 16, one group of locking spring 15 and the oil cylinders 12 of pulling pin.By eight bearing pins four fixture blocks are become a chain form with four rod hinge connections, and by spring locking, when feeding pressure oil for the oil cylinder of pulling pin, this bearing pin is extracted, and makes chain untie, come off, realized that oil transfer arm separated with boats and ships moments.
By figure four as can be known, change-over valve 18 direct control master inlet valve 19 and main fuel-return valves 20, main inlet valve 19 links to each other with the oil cylinder 12 of pulling pin with main fuel-return valve 20, and energy storage 21 links to each other with pump.When emergency situation took place, operating personal was pulled two-position four way change valve 18, and control presssure oil is switched, and main inlet valve 19 is opened, and main fuel-return valve 20 is closed, and pressure oil enters the oil cylinder 12 of pulling pin, and bearing pin is extracted.
