Description
Technical field
The utility model relates to a kind of improvement of oil circuit, particularly the oil circuit of simple gate frame.
Background technology
The simple gate frame oil channel structures of existing fork truck is complicated, easy oil leakage.For this reason, we have developed the simple gate frame oil circuit that a kind of structure is simple and easy to assemble.
Utility model content
The utility model object provides a kind of structure to be simple and easy to the simple gate frame oil circuit assembled to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of simple gate frame oil circuit, comprises pumping plant, fuel tank, pumping plant oil pipe, pumping plant joint, straight coupling, middle cylinder; Described pumping plant is connected by screw with fuel tank; Be provided with valve block in the middle part of described pumping plant, valve block is provided with oil outlet; Described oil outlet is connected with one end of pumping plant oil pipe by pumping plant joint; Described middle cylinder lower end is provided with oil inlet, and oil inlet is connected by the other end of straight coupling with pumping plant oil pipe.
Preferably, described valve block is equipped with electromagnetic valve, when needs piston rod is retracted, open electromagnetic valve, hydraulic oil gets back to fuel tank through straight coupling, pumping plant oil pipe, pumping plant joint, electromagnetic valve successively.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Described the utility model is optimized improvement to traditional simple gate frame oil circuit, and whole oil channel structures is simple, easy to assembly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the assembling stereogram of simple gate frame oil circuit described in the utility model;
Wherein: 1, middle cylinder; 2, straight coupling; 3, pumping plant; 4, valve block; 5, pumping plant joint; 6, fuel tank; 7, electromagnetic valve; 8, pumping plant oil pipe.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is a kind of simple gate frame oil circuit described in the utility model, comprises pumping plant 3, fuel tank 6, pumping plant oil pipe 8, pumping plant joint 5, straight coupling 2, middle cylinder 1; Described pumping plant 3 is connected by screw with fuel tank 6; Be provided with valve block 4 in the middle part of described pumping plant 3, valve block 4 is provided with oil outlet; Described oil outlet is connected with one end of pumping plant oil pipe 8 by pumping plant joint 5; Described middle cylinder 1 lower end is provided with oil inlet, and oil inlet is connected with the other end of pumping plant oil pipe 8 by straight coupling 2; Described valve block 4 is equipped with electromagnetic valve 7.
