Abstract
The utility model relates to a pressure spring balance type crane tube for loading and unloading liquid on the top of a tank car, being composed of an end horizontal gyrator, a middle horizontal gyrator, a middle oscillating gyrator, an end oscillating gyrator, a horizontal short arm, a bend tube, an oscillating long arm, a vertical tube, a pressure spring type balancer, an air release valve, etc. The pressure spring type balancer does not occupy space for operation, and the utility model has the advantages of good balancing performance, safe structure, easy installation and adjustment, convenient operation and maintenance. The structures of the two horizontal gyrator and the oscillating gyrator can be improved, so that the working course of replacing a seal ring can be simplified, and the maintenance of the crane tube can be more convenient. The utility model can be used for loading and unloading liquid on the of tank cars on trains and automobiles.
Description
The utility model relates to a kind of FLUID TRANSPORTATION transfer device, further is meant a kind of stage clip bogie type oil filling riser that is used for train tank car and tank wagon top loading-unloading liquid.
In the past tank car loading and unloading oil filling riser, or to adopt counter weight type, its shortcoming be that to take working space big, inconvenient operation; Or adopt the rear portion to hang bucket formula spring balancing and steel wire tensioner mechanism, also will occupy bigger operational space, and steel rope is perishable and easy to wear under the operating mode, installs simultaneously and adjusts also inconvenience in the open; Adopting the torsion spring balance mode in addition, be CN2079183U " new liquid transfers apparatus for work " as notification number, and there is the problem of poor safety performance in the torsion spring balance mode when the spring wire fracture by fatigue, and balance quality and adjusting function are all relatively poor.In addition, the gyrator design of Sealing Structure of existing oil filling riser is very unreasonable, makes the operation of changing seal ring bother very much.
At the above-mentioned deficiency of prior art, the purpose of this utility model, be provide a kind of structural safety, sealing reliable, install adjust easily, the stage clip bogie type tank car top loading-unloading liquid oil filling riser of convenient operating maintenance.
Solution of the present utility model is as follows.It still comprises in the prior art being possessed can be in horizontal plane rotating end horizontal gyrator and by-level gyrator, swing gyrator and end swing gyrator in the middle of can in vertical plane surface, swinging, horizontal galianconism and the swing that can regulate operating radius are long-armed, can insert the vertical tube in the tank car, and bend pipe and balancing device, horizontal galianconism two ends are connected with an end of end horizontal gyrator and by-level gyrator respectively, the bend pipe two ends are connected with the other end of by-level gyrator and an end of middle swing gyrator respectively, swinging long-armed two ends is connected with the other end of centre swing gyrator and an end of end swing gyrator respectively, balancing device is connected on the long-armed and middle swing gyrator of swing, the other end of the top of vertical tube and end swing gyrator is connected, and swings aie escape valve to be housed on long-armed.Feature part of the present utility model is, the structure of balancing device is, on swing is long-armed, be fixed with the balancing device support, have two risers on the balancing device support, between two risers, has the equilibrator spring tube, two fulcrums on the spring strut cylindrical shell outside are enclosed within respectively in two slotted eyes on the riser, in equilibrator spring tube inside two stage clips are housed, separate with backing plate between two stage clips, also have one in spring strut inside and pass the inner and sliding simultaneously pull bar that passes backing plate of two stage clips, pull bar is in one of spring strut in-to-in the pressing plate that compresses stage clip is housed successively, thrust bearing and setting nut, back end of tie rod also are equipped with and prevent that setting nut from withdrawing from the retaining pin of pull bar; Have the balance adjustment hole on the spring strut bonnet at retaining pin rear, the other end of pull bar then cunning is passed the perforate of equilibrator spring tube end and is connected mutually with a joint, and is hinged with bearing pin between the auricle on joint and the middle swing gyrator cylindrical shell.
The utility model with said structure is taken over the end horizontal gyrator and to be connected in use with user's technology.When off working state, upwards push away vertical tube, drive the angle that the long-armed horizontal axis around centre swing gyrator of swing upwards is rocked to a certain setting, under the effect of contraction of balancing device, make long-armed this position that remains on of swing, oil filling riser is in rounding state.During the loading and unloading tank car, make of the vertical axis revolution of horizontal galianconism around the end horizontal gyrator, make the long-armed vertical axis revolution of swing around the by-level gyrator, thereby regulated the swinging radius of oil filling riser, made oil filling riser can carry out the operation of loading or unloading to the liquid in the tank car in the optional position in the design project radius.With vertical tube forward to can insertion groove roof hand-hole the position, pull down vertical tube again, drive the long-armed horizontal axis around centre swing gyrator of swing to lower swing, up to the bottom that the vertical tube bottom is inserted into tank car.When unloading groove, before the immersed in liquid level of vertical tube bottom, should open aie escape valve, close aie escape valve again after being inserted into the end.During tankage, after tankage finishes, open aie escape valve earlier, upwards dial vertical tube again.In the process of loading or unloading, liquid is all taken over to flow in the tank car or in tank car from technology by oil filling riser and is flowed to the technology adapter.After the loading or unloading operation is finished, oil filling riser is operated to aforementioned rounding state.Swing long-armedly in the process that the horizontal axis around centre swing gyrator swings up and down, swing long-armed gravity torque around this horizontal axis by the balancing device balance, only need just can be operated with very little power.
The equilibrium principle of this compressed spring type balancing device is, when long-armed the swinging up and down of swing, the balancing device support rotates by the bearing pin that the fulcrum on the equilibrator spring tube drives on the spring strut solderless wrapped connection head, the center that makes two fulcrums changes to the distance of bearing pin, under the effect of pull bar and pressing plate, two stage clips obtain respectively compressing or loosening, thus the variation of the long-armed gravity torque in swing process of compensation swing just.The balance adjustment process of compressed spring type balancing device is, puts in the setting nut that the pull bar rear portion is gone to turn in balance adjustment hole on the spring strut bonnet with adjustment means, and thrust bearing changes into the screw motion of setting nut the translation of pressing plate.When needing to strengthen balancing force, tighten setting nut, make the stage clip compression, when needing to reduce balancing force, then unscrew setting nut, stage clip is loosened, regulate till balance.
The utility model adopts the stage clip balance mode, the stage clip balancing device be installed in swing long-armed on, and be connected with rigid member with the non-swing part of oil filling riser, neither take the operational space, overcome employing steel rope bonded assembly defective again.Even the stage clip balancing device still has effect of contraction to oil filling riser under the situation of spring wire fracture by fatigue, thus the safety that has guaranteed to operate oil filling riser.The balance quality of balancing device is fabulous, and the stage clip oil filling riser can realize that in design-calculated pendulum angle scope arbitrary position can both balance.The balance adjustment process of this balancing device is also simple and easy to do.
