Abstract
The utility model discloses a single-action hydraulic cylinder for turning a land leveler engine cover. The single-action hydraulic cylinder comprises a sealing piece, a fixing sleeve, a cylinder barrel, a piston rod, a retaining ring for a shaft, a cylinder base, a damp and filtering screens. The piston rod is arranged in the cylinder barrel through the fixing sleeve, a connector is arranged at the cylinder base position and communicated with the inside of the cylinder barrel, the retaining ring for the shaft is arranged at one end of the piston rod close to the cylinder base, the sealing piece is arranged between the piston rod and the fixing sleeve, the damp is arranged in the connector, the filtering screens are arranged at the oil inlet end and the oil outlet end of the connector respectively, and the connector and the cylinder barrel are sealed through a sealing ring. Compared with a hydraulic cylinder in the prior art, under the condition of inputting the same flow to the hydraulic cylinder, hydraulic cylinder piston rod moving is greatly quickened, the land leveler engine cover is fast in turning and opening, and labor intensity of workers is reduced. In addition, the hydraulic cylinder is free of a piston and the like and can avoid faults of inner leakage, cylinder score and the like. The hydraulic cylinder is integrated with the damp, and the engine cover falls stably.
Description
Technical field
The utility model relates to a kind of grader Engine Casing, specifically is a kind of grader Engine Casing upset single-action hydraulic cylinder.
Background technique
For making things convenient for regular maintenance and maintenance grader engine pack, torque-converters assembly, hydraulic system parts etc., Engine Casing fully need be overturn and open.At present, the upset of grader Engine Casing all realizes by hand pump and double-acting hydraulic cylinder, because the hand pump discharge capacity is little, and double-acting hydraulic cylinder pressure oil active area is big, so the oil hydraulic cylinder slow movement, the Engine Casing reversal rate is slow, and operator's labor intensity is big, after frequent the use, let out in oil hydraulic cylinder is prone to, fault such as scuffing of cylinder bore.
Summary of the invention
Problem at above-mentioned prior art existence, the utility model provides a kind of grader Engine Casing upset to use single-action hydraulic cylinder, and transferring power speed is fast, and the fault point is few, reduce operator's labor intensity greatly, and can not occur that oil hydraulic cylinder is prone in let out, fault such as scuffing of cylinder bore.
To achieve these goals, the utility model grader Engine Casing upset single-action hydraulic cylinder, comprise Sealing, fixed cover, cylinder barrel, piston rod, shaft block ring, cylinder bottom seat, damping and filter screen, piston rod is installed in the cylinder barrel by fixed cover, the cylinder base position is provided with joint and is communicated with cylinder barrel is interior, piston rod is provided with shaft block ring near cylinder bottom seat one end, be provided with Sealing between piston rod and the fixed cover, handicapping Buddhist nun in the joint, joint oil inlet end and oil outlet end are equipped with filter screen, and joint and cylinder barrel seal by seal ring.
As preferably, the damping pore size is 0.8mm, guarantees that Engine Casing falls steadily.
As preferably, filter screen filter precision size is 100 μ m, prevents that large granular impurity from entering in the oil hydraulic cylinder.
Compare with the prior art oil hydraulic cylinder, during to this oil hydraulic cylinder input same traffic, the hydraulic cylinder piston rod movement velocity obviously increases, and the upset of grader Engine Casing is opened fast, reduces labor intensity, secondly, this oil hydraulic cylinder does not have assemblies such as piston, do not let out in not relating to, fault such as scuffing of cylinder bore, moreover, the integrated damping of this oil hydraulic cylinder makes hood fall steadily.

Fig. 2 is mechanism's sectional view of single-action hydraulic cylinder among Fig. 1;
Fig. 3 is I part enlarged diagram among Fig. 2.
Among the figure: 1, Engine Casing, 2, Engine Casing oil hydraulic cylinder bearing, 3, single-action hydraulic cylinder, 4, grader rear bay oil hydraulic cylinder bearing, 5, the bar head, 6, Sealing, 7, fixed cover, 8, cylinder barrel, 9, piston rod, 10, shaft block ring, 11, cylinder bottom seat, 12, joint, 13, filter screen, 14, damping, 15, seal ring.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figures 2 and 3, the utility model grader Engine Casing upset single-action hydraulic cylinder, comprise Sealing 6, fixed cover 7, cylinder barrel 8, piston rod 9, shaft block ring 10, cylinder bottom seat 11, damping 14 and filter screen 13, piston rod 9 is installed in the cylinder barrel 8 by fixed cover 7, cylinder bottom seat 11 places are provided with joint 12 and 8 interior connections of cylinder barrel, piston rod 9 is provided with shaft block ring 10 near cylinder bottom seat 11 1 ends, be provided with Sealing 6 between piston rod 9 and the fixed cover 7, handicapping Buddhist nun 14 in the joint 12, joint 12 oil inlet ends and oil outlet end are equipped with filter screen 13, and joint 12 seals by seal ring 15 with cylinder barrel 8.
As preferably, damping 14 pore sizes are 0.8mm, guarantee that Engine Casing 1 falls steadily.
As preferably, filter screen 13 filter precision sizes are 100 μ m, prevent that large granular impurity from entering in the oil hydraulic cylinder.
As shown in Figure 1, bar head 5 and the cylinder bottom seat 11 with single-action hydraulic cylinder 3 is separately fixed on the grader Engine Casing oil hydraulic cylinder bearing 2 peaceful diji rear bay oil hydraulic cylinder bearings 4; As shown in Figures 2 and 3, when hydraulic oil is imported, flow through successively joint 12, filter screen 13, damping 14, filter screen 13 of hydraulic oil enters in the oil hydraulic cylinder cylinder barrel 8, and when the hydraulic fluid pressure in the cylinder barrel 8 was increased to certain value, pressure oil acted in piston rod 9 cylinder barrels 8 on the ends, promote piston rod 9 motions, Engine Casing 1 upset is opened, and when shaft block ring 10 contacted with fixed cover 7, single-action hydraulic cylinder 3 reached range, at this moment, Engine Casing 1 reaches maximum flip angle.
When no pressure Fuel Tanking Units such as hydraulic oil and fuel tank link in the single-action hydraulic cylinder 3, hydraulic oil flow through successively filter screen 13, damping 14, filter screen 13, joint 12 and flow back into no pressure Fuel Tanking Units such as fuel tank, hydraulic fluid pressure discharges fully, under the gravity effect of Engine Casing 1, piston rod 9 slowly is retracted in the cylinder barrel 8, when an end in piston rod 9 cylinder barrels is retracted to when contacting with cylinder bottom seat 11, piston rod 9 is all withdrawn, and Engine Casing 1 upset falls to horizontal position; Because the throttling action of damping 14, hydraulic oil slowly evenly flows out, and Engine Casing 1 whole dropping process is steady, and the sealing of single-action hydraulic cylinder 3 is finished by Sealing 6 and seal ring 15.
