Delay the installation process of drop valve 5 in the present invention, first by gentle 63 sets of spring of the drop of slow drop valve deck 62 on screw rod 61, so Screw rod 61 is passed through into slow drop spool 68 afterwards, delays drop spring 63 by the gear of blocking step 66 in slow drop spool 68 in slow drop spool 68 Interior, then on the head of screw rod 61, installation self-locking nut 64 is mounted on it on slow drop spool 68, then leads to slow drop spool 68 The internal screw thread 56 crossed in external screw thread 67 and slow drop valve body 6 is fitted in slow drop valve body 6, is then placed in the installation of strainer 53 In slow drop valve body 6, plug 52 is finally mounted on slow drop 6 end of valve body.Slow drop valve 5 is installed.
In use process of the invention, a high position is transported into top, operating position is pushed by foot stand 1, pass through adjusting screw rod 32 regulate required 31 angle of pallet, step on foot-operated 22 by foot after the completion and oil pump 8 is driven to work, and the oil in fuel tank 21 are passed through slow It drops valve 5 and enters oil circuit 7, oil is then being squeezed by oil cylinder 4 by oil pump 8, jack piston rod 41, to drive on pallet 31 It rises, works, after completing work, by trampling fuel outlet valve, so that the oil in oil cylinder 4 is returned to fuel tank 21 by oil circuit 7, returned in oil It flows to during fuel tank 21 oil through too slow drop valve 5, in oil circuit 7 and slow drop spool 68 is entered by the nozzle of slow drop valve 5, by propping up The weight of object is supportted to control the speed of oil reflux, the speed of reflux determines the speed that piston rod 41 declines, the gravity of supporter The speed for making oil flow back is accelerated, and the impact force of oil reflux forms thrust to the slow drop valve deck 62 in slow drop valve 5, makes it through compression Only there are gaps between slow drop spring 63 and slow drop spool 68, to reduce the path of oil reflux, make it that can only pass through gap The oil-through-hole 65 of slow drop spool 68 is flowed into, to flow back into fuel tank 21 by the oilhole 51 on slow drop 6 side wall of valve body, thus living Work is completed in the decline of stopper rod 41.It may be selected to support using foot stand 1 according to actual needs;It can also be by removing bolt for foot prop Component separation, is directly worked using the mode that pedestal 9 supports.
Beneficial effects of the present invention, structure is simple, easy to operate, bracket component 3 be arranged two adjusting screw rods 32 so as to It can be adjusted according to actual needs in 31 angle of head pallet;Universal wheel 15 is time saving and energy saving may be used also for setting on foot prop 11 360 ° of movements;Oil cylinder 4 is fixed with foot stand 1 using Stud connection, it is convenient for disassembly and assembly simple, can also according to circumstances it select at any time It selects the directly placement ground of pedestal 9 or is placed in foot stand 1 and use, therefore is applied widely.It is also provided on oil cylinder 4 A knob 25, convenient for push-and-pull;Piston rod 41 is jacked by the way of foot-operated 22, convenient for force, fuel outlet valve is set, tramples to drain the oil and step on Plate 24 carrys out descending jack, time saving and energy saving also convenient;Slow drop valve 5 is set at inlet port, delays drop valve 5 in oil-absorbing process, oil It postpones and drops the oilhole sucking of valve body 6 and avoid the impurity in oil by the strainer 53 being arranged between slow drop spool 68 and plug 52 Into slow drop valve 5 and oil circuit 7 to result in blockage, then oil enters oil circuit 7 by the oil-through-hole 65 of slow drop spool 68, is inhaling In the process of oil, oil is to move in slow drop valve 5 from top to bottom, so slow drop valve 5 is inoperative same in oil-absorbing process When do not have to also remove, in oil return, oil by fuel outlet valve flow back, while can because supporter weight accelerate oil flow back speed Degree, so that 41 decrease speed of piston rod be made to accelerate, 41 decrease speed of piston rod is too fast, will cause a rebound in moment on earth Power is easy to make the part on pallet 31 is counter shake, fall, damages, and is squeezed by the impact force that slow drop valve 5 is generated when oil flows back Slow drop valve deck 62 in the slow drop valve 5 of pressure delays drop valve deck 62 using the impact force of oil reflux and forms extruding force to slow drop spring 63, makes Only there are gap between slow drop valve deck 62 and slow drop spool 68, oil can only enter the oil-through-hole on slow drop spool 68 by gap 65, to flow back into fuel tank 21 by oilhole 51;By reduce oil reflux when asphalt channel come reduce oil reflux speed, from And reach the speed for reducing the decline of piston rod 41 to guarantee part smooth decreasing on pallet 31, safely;And originally control piston 41 decrease speed of bar is that foot-operated 22 decline of draining the oil once is stepped on by staff's foot, and operating technology is high, needs to operate warp Test foot just can, now by the setting of slow drop valve 5, decline foot-operated 22 need to will only be stepped on, it is not necessary to step on, the side of pine once Formula does not need technology, simple to operate and steady safety.
Above-described embodiment is the description of the invention, is not limitation of the invention, after any pair of simple transformation of the present invention Scheme all belong to the scope of protection of the present invention.
