Abstract
The utility model discloses a piling oil cylinder which comprises a cylinder barrel, a piston rod, a guide sleeve, a seal ring, a rod cavity oil opening and a rodless cavity oil opening. The piling oil cylinder is characterized in that a positioning screw ring is installed in the cylinder barrel at the outer side of the guide sleeve through a thread. The piling oil cylinder provided by the utility model has the advantages of high assembling efficiency and good reliability.
Description
Technical field
The utility model relates to a kind of piling oil cylinder that is used for Static pressure pile driver.
Background technique
Be used for the piling oil cylinder on the Static pressure pile driver at present; As shown in Figure 1; Comprise cylinder barrel 1, piston rod 2, guide sleeve 3, seal ring 7, rod chamber hydraulic fluid port 4 and rodless cavity hydraulic fluid port 5; In the cylinder barrel 1 in guide sleeve 3 outsides, be provided with annular groove, be provided with the card key 8 of segmented in the annular groove, also be provided with positioning ring 9 and back-up ring 10 in card key 8 outsides; This structure is through 8 pairs of guide sleeves of card key, 3 location, but its shortcoming is: 1) assembling difficulty of segmented card key 8 is bigger, and efficiency of assembling is low; When 2) assembling blocks key 8, push away guide sleeve 3 before needing, the seal ring 7 on the guide sleeve 3 may pass through hydraulic fluid port 4, very easily damages Sealing, can't guarantee the reliability of oil cylinder.
The model utility content
The purpose of the utility model is the above-mentioned deficiency to existing technology, and a kind of piling oil cylinder is provided, and it has the advantage of efficiency of assembling height, good reliability.
For achieving the above object, the piling oil cylinder of the utility model comprises cylinder barrel, piston rod, guide sleeve, seal ring, rod chamber hydraulic fluid port and rodless cavity hydraulic fluid port, it is characterized in that in the cylinder barrel in the guide sleeve outside, through screw thread the location wire ring being housed.
The utility model is located guide sleeve through wire ring, and wire ring is easy for installation, and pushes away before guide sleeve need not when wire ring is installed, and seal ring through hydraulic fluid port, can not damage seal ring, has the advantage of efficiency of assembling height, good reliability.
Description of drawings
Fig. 1 is the structure diagram of existing piling oil cylinder.
Fig. 2 is the utility model embodiment's a structure diagram.
Embodiment
are done further detailed explanation below in conjunction with accompanying drawing to the utility model.
By shown in Figure 2, this piling oil cylinder comprises cylinder barrel 1, piston rod 2, guide sleeve 3, seal ring 7, rod chamber hydraulic fluid port 4 and rodless cavity hydraulic fluid port 5, in the cylinder barrel 1 in guide sleeve 3 outsides, through screw thread location wire ring 6 is housed.
The utility model is through 6 pairs of guide sleeves of wire ring 3 location, and wire ring 6 is easy for installation, and pushes away before guide sleeve 3 need not when wire ring 6 is installed, and seal ring 7 through hydraulic fluid port 4, can not damage seal ring 7, has the advantage of efficiency of assembling height, good reliability.
