Accompanying drawing explanation
Fig. 1 is the hydraulic lifting apparatus that the present invention has pipeline explosion-proof function.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of hydraulic lifting apparatus with pipeline explosion-proof function, comprises pipeline safety bursting prevention valve 1, hydraulic ram 2, Hydraulic Pump, handle valve 4, apportioning valve 5, safety valve 6, pressure gauge 7, two T-pipe joints 9 and hydraulic reservoir 10.Described hydraulic reservoir 10 is connected by hydralic hose 8 with Hydraulic Pump, and Hydraulic Pump is connected with safety valve 6, and safety valve 6 is provided with the pressure gauge 7 measuring prexxure of the hydraulic pump.The oil outlet of safety valve 6 is connected with apportioning valve 5 by hydralic hose 8, an oil outlet of handle valve 4 is connected with pipeline safety bursting prevention valve 1 oil inlet (ST mouth) by hydralic hose 8, and another oil outlet of handle valve 4 is connected with hydraulic ram 2 by hydralic hose 8.
First oil outlet of handle valve 4 is connected by hydralic hose 8 with the right oil inlet of apportioning valve 5, second oil outlet of handle valve 4 is connected with apportioning valve 5 left oil inleting port by T-pipe joint 9, and pipeline safety bursting prevention valve 1 hydraulic control mouth (VST mouth) is connected with the second oil outlet of handle valve 4 by T-pipe joint 9.
Safety valve 6 return opening is connected with the first joint of another T-pipe joint 9 by hydralic hose 8, the return opening (L mouth) of pipeline safety bursting prevention valve 1 is connected with the second joint of another T-pipe joint 9 by hydralic hose 8, and the 3rd joint of another T-pipe joint 9 described is connected with hydraulic reservoir 10 by hydralic hose 8.
When the hydraulic lifting apparatus of pipeline explosion-proof function works, bar handle valve 4 rotates the right oil inlet of control ratio valve 5 and opens oil-feed to a direction, at this moment pipeline safety bursting prevention valve 1 oil inlet (ST mouth) oil-feed, then straightwayly hydraulic ram 2 is entered, and hydraulic ram 2 is to the fuel-displaced formation oil circuit of apportioning valve 5, hydraulic ram 2 is made to have stretched out the operation of lifting weight.Then reverse operating handle valve 4, control ratio valve 5 left oil inleting port opens oil-feed, at this moment apportioning valve 5 fuel feeding is to hydraulic ram 2, and hydraulic ram 2 fuel feeding to pipeline safety bursting prevention valve 1, then forms oil circuit by the fuel-displaced apportioning valve 5 of giving of pipeline safety bursting prevention valve 1 oil inlet (ST mouth).When hydraulic ram 2 fuel feeding is to pipeline safety bursting prevention valve 1, pipeline safety bursting prevention valve 1 hydraulic control mouth (VST mouth) is subject to the hydraulic oil that handle valve 4 is provided by T-pipe joint 9, carry out the valve core opening degree of pilot piping safety bursting prevention valve 1 inside, make hydraulic ram 2 start pulsation-free descending motion.
When pipeline safety bursting prevention valve 1 internal pressure is larger, pipeline safety bursting prevention valve 1 will have hydraulic oil to be transported in hydraulic reservoir 10 by T-pipe joint 9 by return opening (L mouth), ensure the safe handling of pipeline safety bursting prevention valve 1.When simultaneously safety valve 6 internal pressure is larger, safety valve 6 with will have hydraulic oil to be transported in hydraulic reservoir 10 by another T-pipe joint 9 by return opening, the normal use of guarantee safety valve 6.
When hydraulic tubing bursts, actv. is controlled its highest descending speed by pipeline safety bursting prevention device, and stops it to decline simultaneously, finally makes it leak freely remain in current location.Substantially increase the safety in utilization of hydraulic ram like this, greatly reduce the losses such as the person because contingency brings, life, property and injury.
More than show and describe groundwork of the present invention, principal character and advantage.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
