Description
Technical field
The utility model is related to a kind of oil cylinder, specifically a kind of workover rig telescopic oil cylinder.
Background technology
Wheeled electrical workover rig is a kind of novel oilfield workover treatment equipment at present, is had safe and environment-friendly, energy saving, efficient
Advantage.And in operation process, due to equipment after Optimal improvements lifting force enhancing, remove that speed is fast, the work frequency adds
Greatly, stringenter to the load capacity for the telescopic oil cylinder for requiring to use, running stability, sealing durability.
For the integrated operation Stability and dependability of coordinating operation equipment, applicant proposed a kind of new technical sides
Case, and provide a kind of workover rig telescopic oil cylinder.
Invention content
The purpose of this utility model is a kind of lightweight of offer and load capacity is big, the speed of service is fast, service life is long
Workover rig two save telescopic hydraulic oil cylinder.
To achieve the above object, the technical solution of the utility model includes cylinder body, piston rod, is located at the cylinder of cylinder body upper end
Head is located at the piston of piston-rod lower end, and the piston rod is equipped with inner cavity, the upper end of piston rod be equipped with big chamber oil inlet and small chamber into
Hydraulic fluid port, the inner cavity are equipped with big chamber oil inlet pipe I, and the upper end of the big chamber oil inlet pipe I and big chamber oil inlet be welded to connect, lower end and work
The lower end of stopper rod is welded to connect and is connected to big chamber.
The piston rod side wall is equipped with multiple oil holes, and inner cavity is connected to by the oil hole with small chamber.
The side wall of the cylinder body is additionally provided with big chamber oil inlet pipe II and small chamber oil inlet pipe.
By above structure, piston rod is arranged to hollow structure, and two big chamber oil inlet pipe and two are respectively set
Small chamber oil inlet pipe, while oil inlet or oil return increase hydraulic oil oil inlet, recirculating oil quantity improves the speed of service, piston rod weight saving
So that load capacity that is more stable and strengthening oil cylinder when stretching out, bouncing back.
Further, the upside of the piston is equipped with the stop collar being socketed with piston rod, improves longer piston rod
Stability.
Further preferred, the inner wall lower end of the stop collar is equipped with flange, the upper end of the stop collar and the upper end of flange
It matches respectively with the outer wall of piston rod.
Due to the adoption of the above technical scheme, the beneficial effects of the utility model are：With the above arrangement, cylinder barrel intensity carries
Height, piston rod weight saving；Piston rod stretches out, retraction speed is speeded and guidance quality and stability improve, and ensure that implement
The Stability and dependability of total quality.
Description of the drawings
The utility model is described further in conjunction with attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1, cylinder body, 2, piston rod, 3, cylinder head, 4, piston, 5, inner cavity, 6, big chamber oil inlet, 7, small chamber oil inlet,

Specific implementation mode
As shown in Figure 1, the utility model includes cylinder body 1, piston rod 2, it is located at the cylinder head 3 of 1 upper end of cylinder body, is located at piston rod
The piston 4 of 2 lower ends, piston rod 2 are equipped with inner cavity 5, and the upper end of piston rod 2 is equipped with big chamber oil inlet 6 and small chamber oil inlet 7, inner cavity 5
Equipped with big chamber oil inlet pipe I 8, the upper end of the big chamber oil inlet pipe I 8 is welded to connect, with big chamber oil inlet 6 under lower end and piston rod 2
End is welded to connect and is connected to big chamber.2 side wall of piston rod is equipped with multiple oil holes 9, and inner cavity 5 passes through the oil hole 9 and small chamber
Connection.The side wall of cylinder body 1 is additionally provided with big chamber oil inlet pipe II 10 and small chamber oil inlet pipe 11.
The upside of piston 4 is equipped with the stop collar 12 being socketed with piston rod 2, and the inner wall lower end of the stop collar 12 is equipped with flange
13, the upper end of the stop collar 12 and the upper end of flange 13 match with the outer wall of piston rod 2 respectively, and will eventually by piston 4
Stop collar 12 is fitted close with piston rod 2.
With the above arrangement, the double hydraulic fluid ports of the utility model oil inlet simultaneously or oil return increases hydraulic oil oil inlet, recirculating oil quantity carries
The high speed of service, the increase of stop collar 12 improves the support distances of piston 4, while 2 weight saving of hollow piston rod makes
Load capacity that is more stable and strengthening oil cylinder when stretching out, bouncing back.
