Abstract
The utility model discloses a pulling tower oil cylinder which comprises a cylinder body and a piston. The piston is movably arranged in the cylinder body, one end of the cylinder body is sealed through a base, the piston is located at the position of one end of the cylinder body sealed by the base and is further fixedly connected with a piston rod, one end of the piston rod far away from the piston is matched with a top cover, one side of the top cover is matched with the cylinder body, the other side of the top cover is matched with the piston rod, the top cover is provided with an oil inlet, the oil inlet is communicated with an oil passage arranged in the top cover, the oil passage is communicated with a cavity positioned in the cylinder body and clamped between the top cover and the piston, the part of the piston rod located in the cavity is sleeved with a spring, one end of the spring is in contact with the top cover, and the other end of the spring is in contact with the piston. The pulling tower oil cylinder is simple in structure, structural setting among the piston, the piston rod, the cylinder body and the top cover is reasonable, the bearing capacity is effectively improved, the service life is effectively prolonged, and the spring can effectively reduce the influence caused by external impact.
Description
Technical field
The utility model relates to a kind of oil cylinder, relates in particular to one and draws tower oil cylinder.
Background technique
Hydraulic jack is as the executive component in Hydraulic Power Transmission System, and playing hydraulic energy transfer is that mechanical energy must act on, and its significance is self-evident, along with the development of industry is also more and more higher to the requirement of hydraulic jack, require high capacity, high-speed, maintenance rate is low, and reliability is high.And the existing tower oil cylinder hydraulic cylinder that draws is all not enough to some extent in sealing and bearing capacity.
Summary of the invention
The purpose of this utility model is in order to solve technical problem related in background technique, provides one to draw tower oil cylinder.
The technical solution of the utility model is: one is drawn tower oil cylinder, comprise cylinder body and piston, described piston is arranged in cylinder body actively, one end of described cylinder body is by base seal, described piston is positioned at one end place of the cylinder body that base seals, described piston is also fixed with piston rod, described piston rod matches with top cover away from one end of piston, one side of described top cover matches with cylinder body, the opposite side of described top cover matches with piston rod, described top cover is provided with filler opening, described filler opening communicates with the oil duct being arranged in top cover, described oil duct communicates with cavity in cylinder body and that be clipped between top cover and piston, described piston rod is positioned at cover in the part of cavity spring, one end of described spring contacts with top cover, the other end contacts with piston.
Preferred as one of the present utility model, on described piston, offer a through hole, described piston rod passes through hole and is connected with piston by nut.
Preferred as one of the present utility model, on described piston rod, be positioned in throughhole portions and offer one for placing the groove of O-ring seals.
Preferred as one of the present utility model, on the outer peripheral surface of described piston, offer three grooves, two grooves in described three grooves are used for placing O-ring seals, and remaining one for placing open type seal ring.
Preferred as one of the present utility model, in described filler opening, be provided with copper filter sheet.
Preferred as one of the present utility model, between described top cover and piston rod, be provided with two seal rings.
In sum, the utlity model has following advantage:
The utility model is simple in structure, fabricating cost is low, by different Sealings is set at different parts, strengthen sealing effect, between piston, piston rod, cylinder body and top cover all parts, structure arranges rationally simultaneously, effectively improved bearing capacity and working life, spring can reduce the impact that external impact is brought effectively simultaneously.
