Brief description of the drawings
Fig. 1 is a kind of side structure schematic view of novel hydraulic rail jack embodiment of the utility model.
Reference in figure, 1- bases, 2- track lifting oil cylinders, 3- oil return valve spanners, 4- fuel tanks, 5- plunger-type fuel pumps, 6- operations
Hand pressure handle, 7- oiling screws, 8- carrying handles.
Embodiment
Reference picture 1 is described further to a kind of novel hydraulic rail jack embodiment of the utility model.
A kind of novel hydraulic rail jack, including base 1, base 1 include front-end and back-end, and the front end of base 1 is provided with
Road oil cylinder 2, track lifting oil cylinder 2 includes the track lifting piston for raising track, and the rear end of base 1 is provided with fuel tank 3, fuel tank 3 and the oil that raises track
Hydraulic circuit is formed between cylinder 2, the rear end of base 1 is also provided with the promotion dress for promoting hydraulic pressure to make track lifting piston increase
Put, pushing meanss include being arranged in fuel tank and for driving the plunger-type fuel pump 5 of track lifting piston rising and for driving plunger
Manipulator's pressure handle 6 that oil pump 5 pumps, is flexibly connected, the rear end side of base 1 between base 1 and manipulator's pressure handle 6
Oil return valve is provided with, the opposite side of the rear end of base, which is provided with overflow valve, base 1, to be additionally provided with for opening or closing oil return valve
Oil return valve spanner 3, fuel tank be provided with oiling screw 7.
Pass through above-mentioned technical proposal so that the utility model carries out track lifting operation by the track lifting piston in track lifting oil cylinder 2,
Track lifting structure needed for substantially reducing, fills in the height of track, therefore only need to track lifting oil cylinder 2 being pushed into rail needed for reducing
Under, manipulator's pressure handle 6 is lifted, track lifting work has been reached, the oiling screw 7 being provided with also can conveniently change oil, it is not necessary to which complete machine is torn open
