Description
Technical field
This utility model belongs to mechanical field, particularly relates to a kind of swing arm energy conserving system adopting reducing balance hydraulic cylinder.
Background technology
Hydraulic crawler excavator is in the course of the work, it is frequent that swing arm swings up and down comparison, hydraulic digger operating device Heavy Weight, inertia are big, produce to be emptied for preventing boom cylinder epicoele too fast because swing arm declines, speed governing is carried out typically via main valve throttling, but during retarding braking, the substantial amounts of potential energy overwhelming majority of equipment is converted into heat energy at main valve restriction, not only causes energy dissipation, also results in system temperature rising and the reduction in hydraulic component life-span.
Section hydraulic excavator arranges energy storage equipment to solve the problems referred to above, but the equilibrant that its energy-storage hydraulic cylinder provides all can change by a relatively large margin, and excavator swing arm to transfer the power of institute's feedback relative stable with the required power that rises, system capacity organic efficiency and system stationarity are all further improved: when swing arm declines, along with accumulator supercharging pressure is gradually increased, the equilibrant of energy-storage hydraulic cylinder is transitioned into greatly from little.When initial topping up, the pressure of accumulator is less, and considerable part potential energy is converted into heat energy by throttling；When swing arm rises, accumulator tapping pressure is gradually reduced, and the auxiliary force that energy-storage hydraulic cylinder provides reduces by a relatively large margin, and the power of former boom cylinder increases accordingly.
Utility model content
For solving the problems referred to above, this utility model provides a kind of swing arm energy conserving system adopting reducing balance hydraulic cylinder.The equilibrant that this utility model provides in swing arm decline process is basically unchanged, when swing arm declines, pressure in accumulation of energy chamber is with the stable rising of little increment, the area of reducing balance hydraulic cylinder is then descending, ensure that reducing balance hydraulic cylinder power output is basicly stable, fully absorb the energy of swing arm institute feedback, improve energy recovery efficiency and system stationarity；When swing arm rises, being gradually reduced at accumulation of energy chamber tapping pressure, the area of reducing balance hydraulic cylinder then ascending reducing balance hydraulic cylinder piston stretches out, and provides for swing arm and stablizes additional force, it is achieved the efficient recycling recovered energy.
For reaching above-mentioned technique effect, the technical solution of the utility model is:
A kind of swing arm energy conserving system adopting reducing balance hydraulic cylinder, including reducing balance hydraulic cylinder, the first former boom cylinder and the second former boom cylinder；The rodless cavity of the first former boom cylinder and the rodless cavity connection of the second former boom cylinder；The rod chamber of the first former boom cylinder and the rod chamber connection of the second former boom cylinder；Reducing balance hydraulic cylinder is connected to Pressure gauge；Reducing balance hydraulic cylinder includes housing, is provided with elastic diaphragm in housing, and elastic diaphragm is connected with the push rod with inclined plane, and push rod is connected to piston；Piston is connected to piston rod；Elastic diaphragm is arranged above accumulation of energy chamber；It it is the first adjustment chamber between elastic diaphragm and piston；It it is the second adjustment chamber below piston；First regulates chamber connects with the second adjustment chamber.
Further improving, described first regulates chamber all connects with low-pressure reservoir with the second adjustment chamber.
Further improving, described push rod connects piston by connecting rod.
Further improving, described push rod is hemispherical.
The equilibrant that this utility model provides in swing arm decline process is basically unchanged, now the pressure in accumulation of energy chamber is with the stable rising of little increment, the effective pressure area of reducing balance hydraulic cylinder is then descending, ensure that reducing balance hydraulic cylinder power output is basicly stable, fully absorb the energy of potential energy institute feedback, improve energy recovery efficiency and system stationarity；When swing arm rises, being gradually reduced at accumulation of energy chamber tapping pressure, and reducing balance hydraulic cylinder stretches out, area is then ascending, provides for swing arm and stablizes additional force, it is achieved the efficient recycling recovered energy.

Detailed description of the invention
Embodiment 1
A kind of swing arm energy conserving system adopting reducing balance hydraulic cylinder as depicted in figs. 1 and 2, including reducing balance hydraulic cylinder the 3, first former boom cylinder 1 and the second former boom cylinder 4；The rodless cavity of the first former boom cylinder 1 and the rodless cavity connection of the second former boom cylinder 4；The rod chamber of the first former boom cylinder 1 and the rod chamber connection of the second former boom cylinder 4；Reducing balance hydraulic cylinder 3 is connected to Pressure gauge 2；Reducing balance hydraulic cylinder 3 includes housing 31, is provided with elastic diaphragm 32 in housing 31, and elastic diaphragm 32 is connected with the push rod 34 with inclined plane, and push rod 34 is connected to piston 33；Piston 33 is connected to piston rod；Elastic diaphragm 32 is arranged above accumulation of energy chamber 38；It it is the first adjustment chamber 37 between elastic diaphragm 32 and piston 33；It it is the second adjustment chamber 36 below piston 33；First regulates chamber 37 connects with the second adjustment chamber 36.
One end (piston rod) of reducing balance hydraulic cylinder 3 is hinged on the bearing pin of excavator swing arm, and the other end is hinged on the bearing pin of excavator turntable.
First regulates chamber 37 all connects with low-pressure reservoir with the second adjustment chamber 36.Push rod 34 connects piston 33 by connecting rod 35.Push rod 34 is hemispherical, it is possible to for inverted cone or other bevelled shape of tool.
Principle of the present utility model is that piston 33 is under pressure, and drives and moves on push rod 34, elasticity of compression barrier film 32, makes the pressure in the accumulation of energy chamber 38 above elastic diaphragm 32 increase, carries out accumulation of energy.Being wrapped up gradually by elastic diaphragm 32 while push rod 34 elasticity of compression barrier film 32, the contact surface of elastic diaphragm 32 and push rod 34 sidewall gives push rod 34 power obliquely, to offset the partial elastic barrier film 32 pressure to push rod 34 upper surface.Along with push rod 34 progressively elasticity of compression barrier film 32, it is more deep to be absorbed in elastic diaphragm 32, gives push rod 34 power obliquely more big, and namely along with the increase of pressure, the effective pressure area of push rod 34 is tapered into by elastic diaphragm 32, it is achieved reducing.Thus maintaining the stability to piston 33 thrust.During the first adjustment chamber 37 pressurized, volume reduces, and makes past second adjustment chamber 36 or the low-pressure reservoir of hydraulic oil (or other liquid or gas etc.) circulation of inside so that elastic diaphragm 32 can carry out deformation.
It is as follows that this swing arm energy conserving system realizes energy-conservation specific works principle:
(1) transfer
When swing arm is transferred.The piston retraction of reducing balance hydraulic cylinder 3, is that pressure can be stored in accumulation of energy chamber 38 by transform gravitational energy, it is achieved the stationarity of the high efficiente callback of energy and guarantee system.
(2) rise
When swing arm rises, accumulation of energy chamber 38 discharges pressure energy, and auxiliary force is stablized in the rising offer for swing arm, it is achieved the efficient recycling recovered energy.
The explanation of above example is only intended to help to understand core concept of the present utility model；Simultaneously for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this specification content should not be construed as restriction of the present utility model.
