Abstract
The utility model belongs to the technical field of mechanical equipment, relates to an oil cylinder and particularly relates to an improved oil cylinder for an excavator. The improved oil cylinder solves the technical problems of poor sealing properties, high cost, low material utilization rate, large oil way consumption and the like of existing oil cylinders. The improved oil cylinder for the excavator comprises a cylinder body, and a piston rod and a piston are arranged in the cylinder body. One end of the piston rod is connected with the piston, and the other end is sleeved in the cylinder body through a support sleeve which is arranged in the cylinder body and connected with the cylinder body. An oil tube is arranged on the cylinder body close to the support sleeve, one end of the oil tube is communicated with the cylinder body and the integral oil tube is parallel with the cylinder body, and the oil tube is fixed on the cylinder body through a fixing mechanism arranged on the cylinder body. The improved oil cylinder for the excavator has the advantages of being reasonable in design, simple in structure, good in sealing properties, high in material utilization rate and capable of reducing oil way consumption and prolonging the service life of the oil cylinder.
Description
Technical field
The utility model belongs to mechanical equipment technical field, relates to a kind of oil cylinder, especially relates to a kind of improved type excavator oil cylinder.
Background technique
Excavator is one of earth moving machinery the most frequently used in the engineering construction, and along with the development of engineering machinery, excavator is used more and more widely.Required various power mainly are by hydraulic oil cylinder driving during excavator work; The oil cylinder of existing technology mainly is single piston actuated, comprises cylinder body, piston, piston rod, guide sleeve and two hydraulic oil pipes, and its shortcoming is that stock utilization is low; Manufacture cost is high; The manufacturing difficulty is big, and sealing is poor, and the oil circuit loss is serious.
In order to solve the problem that existing technology exists, people have carried out long-term exploration, have proposed solution miscellaneous.For example; The Chinese patent document discloses a kind of excavator forearm oil cylinder [application number: 200920023946.4], comprises piston rod, cylinder barrel, piston and cylinder bottom, is provided with guide sleeve at an end of cylinder barrel; The other end is provided with cylinder bottom, and piston rod is linked in the cylinder barrel through guide sleeve; End at piston rod is provided with piston; Be linked in the long end of piston rod at a side place of being adjacent of piston one unsteady cushion collar is arranged; The cushion collar displacement inwall that floats is that cylindrical, outer wall has three oblique flat structures; At the unsteady buffer bar of piston rod afterbody, match with the hole in the cylinder bottom, the buffering modulating valve is inner at cylinder bottom.
Such scheme has improved existing technology to a certain extent, has increased the sealing of oil cylinder.But this scheme not only complex structure, cost is higher, and uses operation inconvenience, stock utilization low, has increased the oil circuit loss simultaneously.
Summary of the invention
The purpose of the utility model is to the problems referred to above, and a kind of reasonable in design, simple in structure, good airproof performance is provided, and stock utilization is high, can reduce the oil circuit loss, the improved type excavator oil cylinder that increases the service life.
For achieving the above object, the utility model has adopted following technical proposal: this improved type excavator oil cylinder comprises cylinder body; In cylinder body, be provided with piston rod and piston; One end of piston rod is connected with piston, and the other end is through being located in the cylinder body and the supporting sleeve that is connected with cylinder body is linked in the cylinder body, and the position near supporting sleeve on cylinder body is provided with oil pipe; Oil pipe one end is whole parallel with cylinder body with cylinder body connection and oil pipe, and described oil pipe is fixed on the cylinder body through the fixed mechanism that is located on the cylinder body.
In above-mentioned improved type excavator oil cylinder, described fixed mechanism comprises the pipe clamp that is located on the cylinder body, and described pipe clamp is connected with oil pipe with cylinder body.
In above-mentioned improved type excavator oil cylinder, described cylinder body is connected with first lining away from an end of supporting sleeve, and described piston rod is connected with second lining near an end of supporting sleeve.
Further, in above-mentioned improved type excavator oil cylinder, described first lining and second lining are processed by copper product.
Compared with prior art, the advantage of this improved type excavator oil cylinder is: reasonable in design, simple in structure, good airproof performance, stock utilization is high, can reduce the oil circuit loss, prolongs the working life of oil cylinder.
