Abstract
A spring cushion chamber arranged at the end of a hinged pin of a hydraulic cylinder is composed of a cylinder barrel 1, a hydraulic cylinder head 2, the hinged pin 3, a piston 4, a spring 5 and a seal seat 6. The spring cushion chamber is characterized in that the hinged pin 3 is a stepped shaft, a stepped blind hole is formed in the center, the piston 4 is arranged in the blind hole, the spring 5 is arranged between the piston 4 and the seal seat 6, the pressure identical with the working pressure of the hydraulic cylinder can be produced when the preload spring force of the spring 5 acts on the piston 4, so that the hinged pin 3 serves as a spring type accumulator, and a left-end chamber of the piston 4 is communicated with a rodless cavity of the hydraulic cylinder through the hydraulic cylinder head 2 and a small hole in the hinged pin 3. According to the spring cushion and release chamber, in the starting process of the hydraulic cylinder, surplus flow can push the piston 4 to compress the spring 5 to enter the left-end chamber of the piston 4, so that the starting impact on the hydraulic cylinder is relieved; when the impact pressure is reduced, pressure oil flowing into the chamber originally flows back to the rodless cavity to do work again under the action of the compressed spring 5, and energy is saved.
Description
One, technical field:
The present invention relates to a kind of spring buffer cavity volume that is arranged on the hinged bearing pin of oil cylinder end.
Two, background technique:
Along with China's industrial expansion, hydraulic transmission has been widely used on all kinds of heavy machinery equipments with control.
Hydraulic jack is topmost executive component in the Hydraulic Power Transmission System.Its performance has played very big effect to the performance of main frame.
Along with hydraulics today towards the development of high-pressure trend and speed up, the startup impact of hydraulic jack and reversing impact have brought very big hydraulic shock to main frame, have caused vibrations and the noise of main frame, very easily cause the early stage damage of hydraulic-pressure pump.Hydraulic shock causes the unnecessary consumption of energy, makes the rapid intensification of host hydraulic system, and then has reduced the viscosity of hydraulic work system medium, and the volumetric efficiency of system descends.
Producing this impact has its reason of being with the starting of load high-acceleration and commutation, and the reason of each equipment cooperation of main frame is arranged, and also has the reason that each major control element rationally mates in its dynamic response transient process in the hydraulic system.At these reasons, people have carried out a large amount of research and discussion, yet these and host work character are inherent, make that people want to take effect very little by the effort that this impact and energy consumption are improved or alleviated to more rational coupling.
At present, on all kinds of high-end hydraulic equipments, the smooth starting of hydraulic jack and energy-conservation buffering are one of difficult problems of puzzlement industry.
Three, summary of the invention:
Purpose of the present invention will be developed a kind of excellent performance exactly, and technology is reliable, the smooth starting of the hydraulic jack of energy-saving and noise-reducing and the new structure of energy-conservation buffering.
The present invention is a kind of spring buffer cavity volume that is arranged on the hinged bearing pin of oil cylinder end, and its structure is combined by cylinder barrel 1, oil cylinder head 2, hinged bearing pin 3, piston 4, spring 5 and sealing seat 6; It is characterized in that: hinged bearing pin 3 is a multidiameter shaft, and there is a ladder blind hole in its center portion, and piston 4 is contained in the big-diameter blind hole that cooperates with it; Be provided with spring 5 between piston 4 and the sealing seat 6; The preloading spring masterpiece of spring 5 is used in and can produces on the piston 4 and hydraulic jack working pressure uniform pressure value, makes hinged bearing pin 3 suitable spring accumulators; The left end cavity volume of piston 4 is connected with the rodless cavity of oil cylinder by the aperture on oil cylinder head 2 and the hinged bearing pin 3.
In the start-up course of oil cylinder, because the speed of oil cylinder has produced hydraulic shock when being in speedup, the unnecessary flow that build-up of pressure impacts can promote further compression springs 5 of piston 4, enters the left end cavity volume of piston 4, and the starting of alleviating oil cylinder is impacted; And when the surge pressure in the oil cylinder rodless cavity reduced, the former fluid that enters piston 4 left end cavity volumes can flow back to rodless cavity under the effect of compressed spring 5, and forced the pressure oil that will be overflowed from relief valve originally to do work again, had saved energy.
This structure is very resultful because the dynamic load of the jib support hydraulic pressure oil cylinder that jib elasticity causes is protected and kept the former fixed position of jib especially for long-armed equipment of concrete mixer class at work.
Four, description of drawings:
Accompanying drawing 1 is structure principle chart of the present invention.
Five, embodiment:
The specific embodiment of the present invention is: in the start-up course of oil cylinder, because the speed of oil cylinder has produced hydraulic shock when being in speedup, the unnecessary flow that build-up of pressure impacts can promote further compression spring 5 of piston 4, enters the left end cavity volume of piston 4, and the starting of alleviating oil cylinder is impacted; And when the surge pressure in the oil cylinder rodless cavity reduced, the former fluid that enters piston 4 left end cavity volumes can flow back to rodless cavity under the effect of compressed spring 5, and forced the pressure oil that will be overflowed from relief valve originally to do work again, had saved energy.
