Abstract
The utility model discloses a gantry oil cylinder which comprises a cylinder body and a piston. The piston is movably arranged inside the cylinder body. One end of the cylinder body is sealed through a base. The piston is located at the end, sealed through the base, of the cylinder body. The end, far away from the base, of the piston is fixedly connected with a piston rod. The end, far away from the piston, of the piston rod is matched with a top cover and an end socket. An oil seal is arranged between the end socket and the top cover. An oil inlet is formed in the end socket and communicated with an upper oil passage in the end socket. The upper oil passage is communicated with a cavity in the piston rod. The cavity is communicated with a lower oil passage formed in the piston. The lower oil passage is communicated with an oil return opening formed in the end of the piston. The gantry oil cylinder is simple in structure and low in manufacturing cost; different sealing elements are arranged on different portions, so that the sealing effect is enhanced; meanwhile, the structural arrangement of the piston, the piston rod, the cylinder body, the top cover and the end socket is reasonable, as a result, the load carrying capacity of the gantry oil cylinder is effectively improved, and the service life of the gantry oil cylinder is prolonged.
Description
Technical field
The utility model relates to a kind of oil cylinder, relates in particular to a kind of gantry 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 existing portal-type hydraulic cylinder 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, and a kind of gantry oil cylinder is provided.
The technical solution of the utility model is: a kind of gantry 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, between described piston and the inwall of cylinder body, be provided with elastic buffering pad, described piston is fixed with piston rod away from one end of base, described piston rod matches with top cover and end socket respectively 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 and end socket, between described end socket and top cover, be provided with oil sealing, described end socket is provided with filler opening, described filler opening communicates with the upper oil duct being arranged in end socket, described upper oil duct communicates with the cavity in piston rod, described cavity communicates with the lower oil duct being arranged in piston, described lower oil duct is communicated with the return opening that is arranged on pistons end.
Preferred as one of the present utility model, the both sides of described elastic buffering pad are provided with fixture block, and the two ends that are positioned at described fixture block are respectively provided with a jacking block; Described fixture block and jacking block are a side and match with piston, and opposite side matches with the inwall of cylinder body.
Preferred as one of the present utility model, described cylinder body outside weld is connected to flange circle.
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, has strengthened sealing effect, between piston, piston rod, cylinder body, top cover and end socket all parts, structure arranges rationally simultaneously, has effectively improved bearing capacity and working life.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a preferred embodiment of the utility model.
