Description
Technical field the utility model relates to a kind of indoor mobile liquid nitrogen container and topple over be contained in the liquid nitrogen in the liquid nitrogen container liquid nitrogen container in go-cart.
Background technology liquid nitrogen (196 ℃) is as a kind of cryogenic coolant, preserves to have obtained using widely aspect seminal fluid, bacterium kind and other active biomaterial in China's animal husbandry, medical treatment and scientific research field.Producing and make the liquid nitrogen container of splendid attire liquid nitrogen, also is a more special industry in China.At present, the liquid nitrogen container made of liquid nitrogen container manufacturer both at home and abroad, its geometric volume are mostly in 1～60 liter of scope, greater than the manufacturing of 60 liters liquid nitrogen containers with use more rare.The demestic user moves and when toppling over the liquid nitrogen container of geometric volume below 60 liters, mostly by manually finishing indoor.When the geometric volume of liquid nitrogen container during less than 30 liters, the weight of liquid nitrogen container own adds the liquid nitrogen weight (liquid nitrogen density is 0.808Kg/L) that fills with below 30 kilograms, and it is still relatively more suitable manually to move liquid nitrogen container this moment and topple over the liquid nitrogen of splendid attire wherein.When the geometric volume of liquid nitrogen container is in 30～60 liters of scopes, to move the liquid nitrogen container difficulty relatively that has filled with liquid nitrogen this moment, if will topple over the liquid nitrogen of splendid attire wherein and must lean on multi agent cooperation to finish.Certainly, also some user, has used hand push (drawing) car that is suitable in some other industrial circles, but has had the following disadvantages when moving the liquid nitrogen container of 30～60 liters of geometric volumes indoor:
1, do not have the function of toppling over the liquid nitrogen in the liquid nitrogen container, topple over liquid nitrogen and still must finish by multi agent cooperation;
There is potential safety hazard when 2, using liquid nitrogen container.These hand push (drawing) car is owing to be not and the supporting use of liquid nitrogen container on the one hand, it is not provided with the device that prevents the liquid nitrogen container overturning in the transportation, transportation exists the liquid nitrogen container overturning to produce damaged in collision, injure the possibility that operator and liquid nitrogen spray the frostbite operator in addition by a crashing object, when toppling over liquid nitrogen, also have frostbite operator's possibility on the other hand:
3, use cost height.These hand push (drawing) car moves indoor on the one hand, generally needs a people to promote dolly, and a people buttresses liquid nitrogen container and prevents to fall: when toppling over liquid nitrogen, also need multi agent cooperation on the other hand, caused the pourability of liquid nitrogen poor, evaporation loss is big.
The summary of the invention the purpose of this utility model be for provide a kind of indoorly make things convenient for mobile liquid nitrogen container, to topple over liquid nitrogen simply laborsaving, has liquid nitrogen container hand barrow safe to use, that cost is low.
The utility model mainly by the castor base, fall bottle rack and convertible anchor ear three parts and form.(referring to Fig. 1, Fig. 2, Fig. 3)
1, above-mentioned caster wheel base is made up of base and five castors, and wherein base and five castors pass through screw attachment.(referring to Fig. 1, Fig. 2, Fig. 6)
Above-mentioned base is welded to form by junction pipe and five spokes, and the upper port of junction pipe has been welded upper end cover, and lower port has been welded bottom end cover; The other end of spoke is welded with the double-screw bolt locating bush, and what wherein rearmounted spoke welded is locating bush.
Rearmounted castor has adopted Side-braking caster wheel in five above-mentioned castors, and all the other four castors are common castor.
2, the above-mentioned bottle rack that falls is connected in by setscrew nut on the locating bush of castor base by left and right support tube, and the port of left and right support tube is welded with locating dowel pin, and welded top has bearing.(referring to Fig. 1, Fig. 2)
3, above-mentioned convertible anchor ear is connected by pin hinge by left and right two semi-ring one ends, and the other end has been riveted left active card, right fixed card respectively, and left active card and right fixed card connect by eyelet bolt and dish shape nut.By selecting the convertible anchor ear of several different-diameters, can adapt to the needs of the liquid nitrogen container of geometric volume in 30～60 liters of scopes.(referring to Fig. 1, Fig. 2, Fig. 7)
Above-mentioned convertible anchor ear two edge welds are connected to trip shaft, so that cooperate with the bearing at the top of falling the bottle rack.
The left and right semi-ring inner cylinder face of above-mentioned convertible anchor ear sticks with glue and posts one deck proof rubber pad.
When needs use the liquid nitrogen container hand barrow,, make the castor base stable on ground level with the brake facing on the tight rearmounted castor of hand-screw.Allow the locating dowel pin of left and right support tube port and the locating bush pre-determined bit on the castor base, tighten the setscrew nut on the left and right support tube, finish down being connected of bottle rack and castor base.Unscrew dish shape nut, convertible anchor ear diameter is unclamped, be inserted in the position of liquid nitrogen container bottom-to-top-height 3/5, tighten dish shape nut again, convertible anchor ear is locked on the liquid nitrogen container external cylindrical surface.Mention liquid nitrogen container then, the trip shaft on the convertible anchor ear is embedded in the bearing at the top of falling the bottle rack.With the brake facing on the rearmounted castor of hand-screw pine, just can freely promote liquid nitrogen container and move flexibly indoor.When needs are toppled over liquid nitrogen in the liquid nitrogen container, brake facing with on the tight rearmounted castor of hand-screw is stabilized in ground level with dolly, catches the liquid nitrogen container bottom upwards to mention with hand, liquid nitrogen container is rotating on the bottle rack by the trip shaft on the convertible anchor ear, just can topple over easily liquid nitrogen.
Compare with hand push (drawing) car in being applicable to general logistics field, the utlity model has following characteristics:
1, has the function of toppling over liquid nitrogen.Convertible anchor ear is locked on the suitable height of liquid nitrogen container external cylindrical surface, by the support of bottle rack, catch the liquid nitrogen container bottom upwards to mention by an operator, liquid nitrogen container just rotating easily on the bottle rack, is poured out liquid nitrogen with convertible anchor ear.
2, safe to use.Liquid nitrogen container is held tightly by convertible anchor ear, is fixed on the bottle rack falling, and in the indoor moving process of hand barrow, idol has Uneven road, does not worry that also liquid nitrogen container topples over, and produces damaged in collision and liquid nitrogen and pours out and injure human body.
3, with low cost.Use the liquid nitrogen container hand barrow just can finish the indoor transportation of liquid nitrogen container and topple over the work of liquid nitrogen by an operator generally speaking, using hand push in other field (drawing) car to need several operators to cooperate finishes, reduce operator's physical labor intensity greatly, also reduced the evaporation loss of liquid nitrogen in toppling process simultaneously.
