Abstract

The utility model discloses a hydraulic jacking equipment for cylinder body movement, comprising a cylinder body, a fixing plate arranged outside of the cylinder body and a guiding ring; a piston rod, a piston head, a guiding sleeve for cylinder end, a return chamber and a pressure chamber are arranged in the cylinder body; an oil inlet is arranged in the piston rod. With the structure of fixed piston rod and movable cylinder body, the utility model has the advantages that the piston rod can be protected effectively from pulling, and the oil leakage phenomena is reduced to the fullest extent, thus the service life for jacking equipment is prolonged.

Description

A kind of hydraulic jacking device of movement of cylinder block

Technical field

The utility model relates to a kind of hydraulic jacking device, and especially a kind of piston rod is fixed, the hydraulic jacking device of movement of cylinder block.

Background technique

Hydraulic jacking device is a kind of machinery commonly used, general jacking apparatus is that piston rod pumps, if the local environment that uses is more abominable, impurity will be adsorbed on the piston rod, piston rod surface is pulled, the effect of sealing is descended, phenomenons such as leakage of oil occur, and the filler opening of jacking apparatus generally is positioned on the cylinder body on the market, and the filler opening connecting means is not too convenient, reliable.

The model utility content

Be vulnerable to foreign material and pull in order to solve piston rod, cause sealing effect to descend, phenomenons such as leakage of oil occur, the utility model discloses a kind of hydraulic jacking device of movement of cylinder block, it comprises cylinder body, is positioned at cylinder body outer fixed plate, guide ring; Be positioned at piston rod, piston head, cylinder mouth guide pin bushing, the backhaul chamber of cylinder body, pressure chamber; Be positioned at the filler opening of piston rod.

Described filler opening is positioned at piston rod inside, and two filler openings are communicated with backhaul chamber and pressure chamber respectively; Described piston rod is fixed on the fixed plate, and piston head is fixed on the piston rod, and cylinder mouth guide pin bushing is fixed on the cylinder body.

Described piston head is fixed on the piston rod by the piston head locknut, and cylinder mouth guide pin bushing is fixed on the cylinder body by cylinder mouth locknut, and piston rod is fixed on the fixed plate by locknut.

Described guide ring is fixed on the support.

The employing piston rod is fixed, the structure of movement of cylinder block, can effectively protect piston rod not pulled, and reduces the phenomenon that the sealing leakage of oil occurs to greatest extent, thereby can prolong the working life of jacking apparatus.

Description of drawings

Below in conjunction with accompanying drawing mode of execution of the present utility model is described.

Figure is the utility model structural representation.

Embodiment

As shown in the figure, piston rod 4 is connected with fixed plate 9 by locknut 7, and the plate 9 that promptly is fixed is fixing, and fixed plate 9 is fixed on the support 10, and guide ring 15 also is fixed on the support 10, simultaneously cylinder body 3 is play the guiding role.

Piston head 2 is fixed on piston rod 4 bottoms by piston head locknut 1, piston head 2 and cylinder body 3, piston rod 4 are formed sealing by seal ring, cylinder mouth guide pin bushing 5 is fixed on the cylinder body 3 by cylinder mouth locknut 6, cylinder mouth guide pin bushing 5 and cylinder body 3, piston rod 4 are formed sealing by seal ring, and filler opening 8 and filler opening 11 are positioned at the top of piston rod.

During jacking, hydraulic oil enters into piston rod 4 bottoms by filler opening 8, piston head 2 and cylinder body 3 decomposition pressure chambeies 12 after hydraulic oil enters into pressure chamber 12, can produce pressure, because piston rod 4 is fixed on the fixed plate 9, piston head 2 is fixed on the piston rod 4, and forms sealing with cylinder body, so piston head 2 maintains static, pressure will make cylinder body 3 travel forward again, realizes cylinder body 3 jacking forward.

During backhaul, hydraulic oil is entered into the inside of piston rod 4 by filler opening 11, enter into backhaul chamber 14 from oil outlet 13, because piston head 2 is fixed on the piston rod 4, hydraulic oil can only promote cylinder mouth guide pin bushing 5 and travel forward, cylinder mouth guide pin bushing 5 is fixed on the cylinder body 3, and cylinder body 3 will move, and realizes the falling of cylinder body 3.
