Abstract

The utility model relates to a pneumatic train crane pipe. Both the inner arm and the outer arm of the pneumatic train crane pipe are composed of hoses, and are hung on a rigid overhang beam through a carriage. The carriage can be moved along the axis of the overhang beam, and the overhang beam which is driven by a cylinder to elevate freely can be rotated around a fixed shaft along a bracket simultaneously. The actions of the cylinder can be manipulated by a control valve which is arranged in a control box on an upright column. In order to conveniently manipulate on a tank car, the utility model can also be operated by a control valve which is arranged at the front end of the overhang beam, and an aligning operating handle is also arranged at the front end of the overhang beam; simultaneously, an emptying device and a sight glass viewing device are arranged on the crane pipe. The crane pipe has the advantages of flexible operation, convenient aligning and labour saving, and can be widely used for liquid filling work in petrochemical processing industry.

Description

Pneumatic train crane pipe

The utility model belongs to a kind of liquid loading and unloading implement, is mainly used in the defeated industry that transfers to of various liquid of petroleum chemical industry.

Existing train liquid tank car transfers in the industry defeated, adopts a kind of implement that is commonly called as the train oil filling riser to carry or extract out liquid usually in slot train.This kind equipment all adds that by solid drawn pipe (or aluminum pipe) swivel coupling and balancing device are formed.Existing implement all exists: operation is heavy, labour intensity is big, the big deficiency that waits of leak of liquid amount.But the relevant document in the detailed technology referenced patent of this class oil filling riser numbers 85201990.4.

It is zero oil filling riser that the purpose of this utility model is to provide a kind of labor intensity of operating personnel, leak of liquid amount of alleviating.

Support that this oil filling riser by a cylinder supports (beam) and a pair of hose set are formed, its hose set hangs on the rack beams, support can drive the hose set rotation, be used for the centering goods yard, the up-and-down movement of cylinder balancing and promotion beam, thus make that insertion and the extraction of flexible pipe from tank car is very light.

Contrast the main contents of this oil filling riser of description of drawings below.

Fig. 1 is the utility model structural representation.

Can find out that from accompanying drawing the utility model comprises that inner arm (1), outer arm (2), column (3), support (4), rigidity cantilever beam (5), lift cylinder (6) and control box major parts such as (7) form.Inner arm (1) and outer arm (2) are that a pair of flexible pipe constitutes, and are linked to be a passage by 90 ° of bend pipes (8).In order to prevent outer arm (2), support set in (9) is housed at the bend pipe (8) and outer arm (2) the bonded assembly mouth of pipe at bend pipe (8) junction slight crack.In the both sides, middle part of bend pipe (8) active pin shaft (10) is arranged respectively, kink is on dolly (11), and dolly (11) hangs over the front portion of rigidity cantilever beam (5), and can move forward and backward along the axis direction of beam (5), so that it is more convenient when outer arm (2) inserts, the switch (13) of one signaling handle (12) and control cylinder (6) motion is housed at the leading section of beam (5), and a restriction dolly (11) limiting stopper of range of movement (14) backward is housed at the middle part of beam (5), the rearward end of beam (5) links to each other with support (4) by active pin shaft (15), and can make horizontal rotation around axis (16) with support (4).The lower end, rear portion of beam (5) has an active pin shaft (17) to link to each other with cylinder (6).Beam (5) can swing up and down along with the flexible of cylinder (6).In the upper end of support (4) elastic hook (18) is housed, can works as oil filling riser when rising to vertex, automatically beam (5) is tangled.In order to guarantee the rotary stability of support (4), support (4) the untie-sell axle of together being indecisive and changeable (19,20) respectively is housed up and down, bearing pin (19,20) links to each other with column (3) kink.On this external column (3) control box (7) is housed, control cock (21) is housed in the case, control cock (21) upper plate can make hook (18) and beam (5) break away from, and lower plate control cock (21) just makes beam (5) be with inner arm (1) and outer arm (2) to fall then, thereby inserts the tank car mouth.Dolly in the process (11) Ke Yanliang (5) axial motion, the external arm tube group can be rotated around axis (16) in simultaneously beam (5) had been with, like this with regard to more convenient to bit manipulation.After operation finishes, glide because of beam (5) rises, on dolly (11), be provided with a centering type clamp handle (22) in order to prevent dolly (11).The rising or falling speed of cylinder (6) can be regulated by purpose made dihedral governor valve (23).Because of big wind rolling, between column (3) and support (4) lower bearing pin (20), be provided with a windproof pin (24) for fear of device.In beam (5) decline undue buckling phenomenon appears for fear of inner arm (1), be provided with an elastic bracket (25) at inner arm (1) lower flange interface, and the visor (27) of liquid flowing state in the observation tube and the entrucking unidirectional cock (28) that the back mends air that finishes is housed on oil filling riser pedestal connecting bend (26).Lower port at outer arm (2) is equipped with a usefulness reinforced rib with claw bonded assembly pin (29), and it is curved to avoid claw to bump.Handrail (12) and control cock (13) are provided with for handled easily on tank car, and the gas circuit control pipeline moving part of package unit all adopts corrugated stainless steel tubing (31), all the other fixed parts copper pipe (30).

The utility model is because the connection of its flow channel for liquids all is a static seal, thereby the phenomenon of having avoided gyrator in the past to leak, improved sealing reliability, and because of the minimizing of runner elbow, access height reduces, thereby the flow resistance loss of pressure of the pipeline that reduces is accelerated handling speed, shorten production time, what is more important has been improved operating environment.Because of the oil filling riser lifting promotes voluntarily by cylinder, avoided the phenomenon of artificial portable oil filling riser, so greatly decrescence light operator's labour intensity can be widely used in having good society and economic benefit in the train tank car liquid loading and unloading operation of oil and chemical industry operation.
