Abstract
The utility model discloses a kind of support leg of pump truck oil cylinder, it is characterized in that, cylinder bottom is welded with in one end of cylinder barrel, oil return through-hole is provided with in the interior of described cylinder barrel, one end of oil return through-hole connects with the spill port on cylinder bottom and is connected, and the other end of oil return through-hole and one end inner chamber of cylinder barrel connect, and guide sleeve is located on the other end inwall of cylinder barrel, piston rod inserts in cylinder barrel through guide sleeve, and piston is located at by locking nut one end that piston rod stretches into cylinder barrel.By above setting, the utility model, without the need to the arranged outside return tube at cylinder barrel, reduces cylinder body volume, reduces cylinder body weight, and can not cause damage because of operating environment when operation, guarantees oil cylinder working life.
Description
Technical field
The utility model relates to a kind of oil cylinder, is a kind of support oil cylinder on pump truck specifically.
Background technique
Support oil cylinder at present on pump truck, its return tube mostly is design outside cylinder barrel, when oil cylinder operation, because operating environment is complicated, as easy as rolling off a log by return tube damage, causes unnecessary damage.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, the support leg of pump truck hydraulic jack of long service life.
To achieve these goals, the utility model is welded with cylinder bottom in one end of cylinder barrel, oil return through-hole is provided with in the interior of described cylinder barrel, one end of oil return through-hole connects with the spill port on cylinder bottom and is connected, the other end of oil return through-hole and one end inner chamber of cylinder barrel connect, guide sleeve is located on the other end inwall of cylinder barrel, and piston rod inserts in cylinder barrel through guide sleeve, and piston is located at by locking nut one end that piston rod stretches into cylinder barrel.
By above setting, the utility model, without the need to the arranged outside return tube at cylinder barrel, reduces cylinder body volume, reduces cylinder body weight, and can not cause damage because of operating environment when operation, guarantees oil cylinder working life.
Accompanying drawing explanation
Now by reference to the accompanying drawings the utility model is described further.
Fig. 1 is structural representation of the present utility model.
In figure: 1, cylinder barrel, 2, cylinder bottom, 3, oil return through-hole, 4, spill port, 5, guide sleeve, 6, piston rod, 7, piston, 8, locking nut, 9, oil inlet hole.
Embodiment
As shown in Figure 1, the utility model is welded with cylinder bottom 2 in one end of cylinder barrel 1, oil return through-hole 3 is provided with in the interior of described cylinder barrel 1, one end of oil return through-hole 3 connects with the spill port 4 on cylinder bottom 2 and is connected, the other end of oil return through-hole 3 and one end inner chamber of cylinder barrel 1 connect, guide sleeve 5 is located on the other end inwall of cylinder barrel 1, and piston rod 6 inserts in cylinder barrel 1 through guide sleeve 5, and piston 7 is located at by locking nut 8 one end that piston rod 6 stretches into cylinder barrel 1.By above setting, the utility model is arranged on the supporting leg of pump truck, during pump truck work material conveying, just the support oil cylinder of pump truck must be opened support car body, hydraulic oil enters the inside of cylinder barrel 1 by the oil inlet hole 9 on the utility model cylinder bottom 2, promotes piston 7 and moves downward, piston rod 6 stretches out, until the bearing of piston rod 6 one end and earth surface, support pump truck car body, make pump truck held stationary.When needs piston rod 6 resets, hydraulic oil enters into one end of cylinder barrel 1 by oil return through-hole 3, and hydraulic oil promotes piston 7 and moves upward, and piston rod 6 is retracted and resetted.
