Abstract
The invention discloses a full-free double-door frame oil way used for a low space. The full-free double-door frame oil way used for the low space comprises a pump station, an oil tank, a pump station oil pipe, a first steel pipe, a second steel pipe, a first oil pipe, a front middle cylinder and a rear middle cylinder; a valve block is arranged at the middle of the pump station, and an oil outlet is formed in the valve block; the oil outlet is connected with a pump station joint, a pump station oil pipe and a first steel pipe in sequence; the second steel pipe is provided with a first joint, a second joint and a third joint; the other end of the first steel pipe is connected with the first joint; the front cylinder is connected with the second joint; the third joint is connected with the second oil pipe, a right-angle connector and a rear cylinder in sequence. The full-free double-door frame oil way used for the low space is specially used for the low space, and side cylinders at two sides of the traditional double-door frame are replaced by the front middle cylinder and rear middle cylinder; when a forklift carries goods, the height of the forklift is not changed; the full-free double-door frame oil way used for the low space is capable of meeting the needs of working in the low space with limited height, such as containers.
Description
Technical field
The present invention relates to a kind of improvement of two-door frame oil circuit, particularly the two-door frame oil circuit of a kind of full freedom be applied in short space.
Background technology
The two-door frame oil circuit of existing electric piling car makes vehicle when transporting goods, and car load height can increase along with the lifting of pallet fork, cannot work in the space of height-limited system.For this reason, we have developed the two-door frame oil circuit of a kind of full freedom be applied in short space.
Summary of the invention
The present invention seeks to provide a kind of full freedom be applied in short space two-door frame oil circuit to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution used in the present invention is: the two-door frame oil circuit of a kind of full freedom be applied in short space, comprises pumping plant, fuel tank, pumping plant oil pipe, the first steel pipe, the second steel pipe, the first oil pipe, front middle cylinder, rear middle cylinder; Be provided with valve block in the middle part of described pumping plant, valve block is provided with oil outlet; Described oil outlet connects pumping plant joint, pumping plant oil pipe, the first steel pipe successively; Described second steel pipe is provided with the first joint, the second joint, the 3rd joint; The other end of described first steel pipe is connected with the first joint; Described front cylinder is connected with the second joint; Described 3rd joint connects the second oil pipe, nipple bent piece, rear cylinder successively.
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 nipple bent piece, the first oil pipe, the second steel pipe, the first steel pipe, pumping plant oil pipe, pumping plant joint, electromagnetic valve successively.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Described the present invention, specially for the operating mode in short space, is optimized traditional double door frame oil circuit, arranges front middle cylinder, rear middle cylinder before and after being replaced to by the limit cylinder of former both sides.When fork truck is when transporting goods, car load height is constant, can meet the demand worked in the short space of height-limited system.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the assembling stereogram of the two-door frame oil circuit of the full freedom be applied in short space of the present invention;
Wherein: 1, the second oil pipe; 2, nipple bent piece; 3, rear middle cylinder; 4, front middle cylinder; 5, right second steel pipe; 6, the first steel pipe; 7, pumping plant oil pipe; 8, fuel tank; 9, pumping plant joint; 10, valve block; 11, pumping plant; 12, electromagnetic valve.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is the two-door frame oil circuit of the full freedom be applied in short space of the present invention, comprises pumping plant 11, fuel tank 8, pumping plant oil pipe 7, first steel pipe 6, second steel pipe 5, first oil pipe 1, front middle cylinder 4, rear middle cylinder 3; Be provided with valve block 10 in the middle part of described pumping plant 11, valve block 10 is provided with oil outlet; Described oil outlet connects pumping plant joint 9, pumping plant oil pipe 7, first steel pipe 6 successively; Described second steel pipe 5 is provided with the first joint, the second joint, the 3rd joint; The other end of described first steel pipe 6 is connected with the first joint; Described front cylinder 4 is connected with the second joint; Described 3rd joint connects the second oil pipe 1, nipple bent piece 2, rear cylinder 3 successively; Described valve block 10 is equipped with electromagnetic valve 12.
During use, pumping plant 11 by hydraulic oil from sucking-off fuel tank 8, hydraulic oil successively through pumping plant joint 9, pumping plant oil pipe 7, first steel pipe 6, second steel pipe 5, first oil pipe 1, nipple bent piece 2 enter front cylinder 4 and after cylinder 3, indirectly drive the piston rod of front cylinder 4 and rear cylinder 3 to stretch out; When needs piston rod is retracted, open electromagnetic valve 12, hydraulic oil returns fuel tank 8 by crude oil road.
Described the present invention, specially for the operating mode in short space, is optimized traditional double door frame oil circuit, arranges front middle cylinder, rear middle cylinder before and after being replaced to by the limit cylinder of former both sides.When fork truck is when transporting goods, car load height is constant, can meet the demand worked in the short space of height-limited system.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
