Further, oil cylinder 12 offers connection air cavity 31 and extraneous oil cylinder venthole 5, specifically, oil cylinder venthole 5 is opened
On pedestal 19, when injecting hydraulic oil in oil cylinder hydraulic chamber 32, piston 9 is slided towards the direction of pedestal 8, hydraulic cavities 32
Volume increases, and the volume reducing of air cavity 31, and the external world can be discharged in the gas in air cavity 31 by oil cylinder venthole 5, so that air cavity
Stable air pressure is remained in 31, when pitch brace 11 is pulled out from oil cylinder 12, pitch brace of the piston 9 towards oil cylinder 12
Exit sliding, the volume reducing of hydraulic cavities 32, and the volume of air cavity 31 increases, air cavity 31 passes through oil cylinder venthole 5 from the external world
Make-up gas is sucked, so that remaining stable air pressure in air cavity 31.
In the present embodiment, in order to keep the stable gas pressure in fuel tank 1, fuel tank venthole 2 is offered at the top of fuel tank 1
So that the inner cavity of fuel tank 1 is connected with the external world.
In the present embodiment, it in order to enable force is more laborsaving and convenient manually, is connected on plunger 13 conventional
Lever mechanism (does not regard) in figure, and specifically, lever mechanism includes rocking bar, and the end of rocking bar is articulated with by the side of plunger 13,
And the shaft that the top of plunger 13 is articulated with rocking bar is connected, according to well known lever principle, rocking bar is longer, plunger 13 closer to
The hinged end of rocking bar, then it is more laborsaving that the head end for shaking rocking bar, which drives the movement of plunger 13,;Operator is by above mentioning rocking bar
Head end can drive plunger 13 to move up, and the head end by pushing rocking bar can drive plunger 13 to move down.
In the present embodiment, specific use process and principle are as follows, and in the initial state, pitch brace 11 stretches to oil
Cylinder 12 it is interior intracavitary, piston 9 acts against on the bottom wall of the inner cavity of oil cylinder 12;It is needed before use by manually first to pitch brace 11
Hanging ring 7 on end applies pulling force with the intracavitary pull-out out of oil cylinder 12 by pitch brace 11, needs to open in this process and unload
Emptying valve 25 on oil pipe line is drawn so that the hydraulic oil in the hydraulic cavities 32 of oil cylinder 12 is back to 1 inner cavity of fuel tank when by piston
(extreme position i.e. piston 9 abuts against limit in the pitch brace exit of oil cylinder 12) is piston when bar 11 is pulled out to extreme position
The maximum stretching state of pull rod 11 at this point, emptying valve 25 is closed, and the hanging ring on 11 head end of pitch brace is mounted on pre-
On the hook for the hanger being equipped with, and the pull ring 22 on pedestal 19 is then for weight (weight and the pedestal 19 of promotion needed for mounting
Pull ring 22 between the connector being preset with such as wirerope, iron hoop chain or connecting rod can be used be attached), install
Afterwards, if the head end that operator above mentioned and pushed repeatedly rocking bar drive plunger 13 back and forth pull-up and under push away, will be in fuel tank 1
Hydraulic oil is successively drawn by inlet line, cylinder barrel 14 and pipeline road into the hydraulic cavities 32 of oil cylinder 12 again, due to work
Plug pull rod 11 is fixed setting (i.e. piston 9 is fixed setting) in the present embodiment, and filling in hydraulic oil into hydraulic cavities 32 makes
During the volume of hydraulic cavities 32 increases, oil cylinder 12 and its 19 entirety of pedestal will receive lifting force upward and promoted upward, from
And drive weight to be promoted by the pull ring of pedestal 19 22, when piston 9 abuts against the bottom wall of 12 inner cavity of oil cylinder again, to mention
The maximum height risen;And since the diameter of plunger 13 is much smaller than the diameter of piston 9, according to well known " pascal's principle ", as long as
Apply lesser power on plunger 13, biggish power can be generated on piston 9, in conjunction with lever mechanism, reaches good laborsaving
Effect so that operator apply certain power can the biggish weight of lifting weight.
In the present embodiment, in order to improve the leakproofness that entire hand hoisting is hung to avoid the leakage of hydraulic oil, fuel tank 1
The junction of cabinet and pedestal 19 is equipped on the groove of the cabinet insertion of oil feeding reservoirs 1 on the second sealing ring 15(, that is, pedestal 19 and lays
Have the second sealing ring 15), it is provided between the pitch brace outlet 23 of oil cylinder 12 and pitch brace 11 for obstructing hydraulic oil
Third sealing ring 21.
In the actual manufacturing, the length of the length and pitch brace 11 that increase by 12 inner cavity of oil cylinder, which can be increased, to be mentioned
The effective travel risen, can be increased the altitude range of promotion.
Embodiment two:
Referring to shown in attached drawing 2, the difference between this embodiment and the first embodiment lies in: air cavity 31 is located at the top of hydraulic cavities 32, oil cylinder
12 pitch brace outlet 23 is opened in the bottom of oil cylinder 12, i.e. the pitch brace outlet 23 of oil cylinder 12 is opened on pedestal 19,
Hanging ring 7 is anchored on the top of oil cylinder 12 by the first fastening nut 6, and pull ring 22 takes shape in the head end of pitch brace 11;Secondly,
Pipeline road is the oil transportation canal road 18 being opened in pedestal 19, and unloading line is the emptying canal road being opened in pedestal 19
24, compared with embodiment one, unloading line and pipeline road are only opened on pedestal 19, and the difficulty for manufacturing production is lower;
In actual use, the hanging ring 7 at the top of oil cylinder 12 is mounted on the hook for the fixation hanger being preset with, and pitch brace
Pull ring 22 on 11 head end is for mounting weight, and in lifting process, oil cylinder 12 is fixed setting, and pitch brace 11 is upward
Fang Shangsheng drives weight to be promoted upward.
In some more preferably embodiments, the fixation of oil cylinder 12 does not use upper lift ring 7, but is directly consolidated by what is be preset with
Fixed rack is directly supported or fixes to the pedestal 19 of oil cylinder 12, and structure is more firm, and lifting process is more stable.
