Abstract
The invention discloses a loading arm with a compacting and sealing spring cylinder, belongs to the technical field of fluid loading and unloading equipment, and solves the problems of environmental pollution and damage to physical health of personnel caused by escape of toxic and easily volatile gas from a gap between a loading arm sealing cap and a tank car opening due to sinking of the tank car in loading operation during sealing of the loading arm without the help of an air cylinder. The loading arm is characterized in that one end of the cylinder body of the rotary compacting spring cylinder is hinged to a loading arm outer arm fixing bracket, and one end of a cylinder rod is hinged to a loading arm inner and outer arm connecting bend end-close-to-outer-arm fixing bracket. According to the loading arm, a loading arm outer arm and the loading arm sealing cap can move down under the action of elastic force of the spring of the rotary compacting spring cylinder, so that the loading arm sealing cap can move down along with the tank car opening at the same time, the gap cannot be formed, and the environmental pollution and the damage to the physical health of personnel due to escape of the toxic and easily volatile gas can be avoided.
Description
Technical field the invention belongs to fluid assembly and disassembly equipment technical field.
Technical background is current, all utilizes airtight oil filling riser to train, poisonous, the volatile fluent of tank-truck loading both at home and abroad.In actual car loading operation, along with liquid weight in tank car increases, tank car can sink, and like this, between sealing cap of oil filling riser and tank car tank mouth, can produce gap, and poisonous, volatile gas is overflowed, contaminated environment, infringement personnel health.In order to address this problem, normally a cylinder is attached on oil filling riser, with cylinder, oil filling riser outer arm or sealing cap of oil filling riser are exerted pressure downwards, make sealing cap of oil filling riser in car loading operation, envelope is pressed on tank car tank mouth all the time, does not produce gap.But the tank car handling places such as at present a lot of oil depots do not have source of the gas, can not utilize cylinder power-assisted oil filling riser sealing entrucking.
Summary of the invention the object of this invention is to provide a kind of spring cylinder and compresses closed charging oil filling riser, in the situation that there is no source of the gas, do not rely on cylinder power-assisted, in car loading operation, also can allow sealing cap of oil filling riser seal all the time and push down tank car tank mouth, do not produce gap, avoid poisonous, volatile gas effusion contaminated environment, infringement personnel health.
Spring cylinder of the present invention compresses closed charging oil filling riser, comprises closed charging oil filling riser and rotatably compresses spring cylinder.Embodiment is: rotatably compress spring cylinder one end by one and be hinged on airtight oil filling riser outer arm, the other end is hinged on the outer arm end of the inside and outside arm connecting bend of oil filling riser fixed support.Rotatably compress spring cylinder, spring force is acted on oil filling riser outer arm, the downward component of this application force, can make oil filling riser outer arm to bottom offset.When car loading operation, first, by oil filling riser and the contraposition of tank car tank mouth, make sealing cap of oil filling riser cover tank car tank mouth, then rotatably compress the spring in spring cylinder, make oil filling riser outer arm produce a downward pressure, sealing cap of oil filling riser can tightly be pressed on tank car tank mouth.In car loading operation, when tank car tank mouth is during to bottom offset, oil filling riser outer arm also can be thereupon to bottom offset, and sealing cap of oil filling riser can seal all the time and be pressed on tank car tank mouth, does not produce gap.Like this, without cylinder power-assisted, also can make oil filling riser sealing car loading operation, avoid poisonous, volatile gas effusion contaminated environment, infringement personnel health.
Brief description of the drawings Fig. 1 is structural representation of the present invention, and Fig. 2 is the birds-eye view of figure mono-.In figure: 1---oil filling riser inner arm, 2---the outer arm end of the inside and outside arm connecting bend of oil filling riser fixed support, 3---rotatably compress spring cylinder, 4---fixed support, 5---spring cylinder rotatably compresses wheel, and 6---oil filling riser outer arm, 7---sealing cap of oil filling riser, 8---oil filling riser vertical tube.
Detailed description of the invention as shown in Figure 1 and Figure 2, is hinged on the cylinder body one end that rotatably compresses spring cylinder 3 on airtight oil filling riser outer arm fixed support 4, and the cylinder bar one end that rotatably compresses spring cylinder 3 is hinged on the outer arm end of the inside and outside arm connecting bend of oil filling riser fixed support 2.Also the cylinder body one end that rotatably compresses spring cylinder 3 can be hinged on the outer arm end of the inside and outside arm connecting bend of oil filling riser fixed support 2, the cylinder bar one end that rotatably compresses spring cylinder 3 is hinged on airtight oil filling riser outer arm fixed support 4.When operation, in oil filling riser vertical tube 8 enters tank car tank mouth and sealing cap of oil filling riser 7 seal after tank mouth, torsional spring cylinder rotatably compresses wheel 5, make to rotatably compress spring cylinder 3 inner springs and produce elastic force, rotatably compress spring cylinder 3 and can produce an application force to oil filling riser outer arm 6, the downward component of this application force, can make the seal cap 7 on oil filling riser outer arm 6 below oil filling riser vertical tubes 8 tightly push down tank car tank mouth, when liquid weight in tank car increases, when tank car sinks, sealing cap of oil filling riser 7 can envelope be pushed down tank car tank mouth, sink with tank car tank mouth, make sealing cap of oil filling riser and tank car tank mouth not produce gap.Like this, without cylinder power-assisted, also can make oil filling riser sealing car loading operation, avoid poisonous, volatile gas effusion contaminated environment, infringement personnel health.
