Description
Technical field
The utility model relates to a kind of large oil filling riser seal cover cap, belongs to oil storage and transportation technical field.
Background technology
The transport of China's clean cargo is mainly taking rail tank car as means of delivery, and the entrucking of truck tanker normally adopts the mode of top loading.Entrucking mode is mainly divided into little oil filling riser and two kinds of large oil filling risers, because the large crane tube load time is short, degree of automation is high, maintenance management is convenient, is large oil filling riser so at present normally used.
In prior art, the large oil filling riser conventionally adopting is the large oil filling riser of hydraulic pressure in immersion.Its simple working process is: large oil filling riser is in a high position, first truck tanker is under draw gear drives, and wagon spout carries out the thick contraposition in horizontal direction with large oil filling riser, then large oil filling riser and the contraposition of wagon spout essence, line of centers in large oil filling riser vertical direction is aimed at, sealing entrucking with wagon spout.
The weak point that above-mentioned prior art exists is: 1) smart contraposition is manually naked eyes judgement in monitoring, is difficult for aiming at, and large oil filling riser and wagon spout can not coincide, and cause large oil filling riser poorly sealed, causes oil product volatilization in entrucking process; 2) in the time filling second truck tanker, large oil filling riser is in a high position, and large oil filling riser bottom is uncovered, fills lower of the residual oil product of first car, causes oil product waste, foul air, and has potential safety hazard.
Summary of the invention
The utility model provides a kind of large oil filling riser seal cover cap, and it can realize dislocation sealing, easy and simple to handle, and sealing is reliable, has solved problems of the prior art.
The concrete technical scheme adopting of the utility model is:
A kind of large oil filling riser seal cover cap, comprises sealing member, and engine installation and gas vent are set on sealing member, under sealing member, along being provided with rubber gasket, it is characterized in that, also comprise mobile cylindrical shell, mobile cylindrical shell is provided with guide rail and coordinates with engine installation, on mobile cylindrical shell, be also provided with arc guide groove, in mobile cylindrical shell, be provided with latch segment, latch segment coordinates with guide groove, also comprise oil filling riser, oil filling riser is through sealing member and mobile cylindrical shell, and oil filling riser is provided with hydrodynamic reciprocating sealing piece, with mobile cylindrical shell fitted seal.
Wherein, the preferred cylinder of described engine installation, hydraulic actuating cylinder, air motor etc.
It is to allow latch segment produce outside compound motion upwards that the utility model adopts the object of arc guide groove, should think like this, adopts the guide piece of other shapes or form identical in essence with arc guide groove, all within the utility model protection domain.
Wherein, the preferred notch cuttype of described latch segment, can be suitable for the car mouth of different size like this.
When making the utility model exit wagon spout, blanketing gas outlet, the utility model arranges gas phase packing seal in gas vent, and gas phase packing seal is connected with engine installation.
Wherein, described hydrodynamic reciprocating sealing piece is preferably oval, square, circular, and the hydrodynamic reciprocating sealing piece of this form easily obtains, saves material.Should think like this, also can adopt the hydrodynamic reciprocating sealing piece of other shapes, as long as and moving cylinder physical efficiency fitted seal.
Preferably, the utility model is provided with and connects liquid device in the bottom of oil filling riser, described in connect liquid device and comprise housing, housing bottom is provided with sealing member and is connected with the springing being arranged in housing, is also provided with multiple locking bars on housing.
For realizing auto lock, the free end stretched dimensions of the preferred locking bar of the utility model is greater than wagon spout size, and in the time that oil filling riser exits wagon spout, due to barrier effect, locking bar moves downward automatically, and locking connects liquid device.
Compared with prior art, the utility model has the advantages that:
1) the utility model will sealing member and the accurate positioning instant of wagon spout can realize dislocation sealing, easy and simple to handle, sealing is reliable;
2) the utility model dress can be avoided lower of the residual oil product of large oil filling riser, causes oil product waste, foul air.
Brief description of the drawings
