Description
Technical field
The present invention relates to a kind of hydraulic cylinders, and in particular to a kind of carrying that turns to of polysilicon solar cell chip is set
It is standby.
Background technique
Solar energy refers to the infrared radiant energy of the sun, is a kind of renewable resource, have measure it is big, harmless, generally etc. many excellent
Point.The history of human use's solar energy can trace back to ancient times people using sunshine article, production food etc..And now people
Demand to solar energy has no longer been the thermal energy for merely utilizing the sun.1615, French engineer's Cox invented the world
The engine of upper First Driven by Solar Energy opens the utilization history of modern age solar energy.
Solar panel, which refers to, turns solar radiant energy by the way that photoelectric effect or photochemical effect are direct or indirect
Change the device of electric energy into.Solar panel is primarily now applied to traffic, communication, oil drilling platform, street lamp, photovoltaic electric
The numerous areas such as stand, other than above-mentioned field, solar panel be also used in remote segment areas without electricity such as plateau,
The place such as pastoral area or frontier sentry is the household electricity that the army and the people provide.
When being applied to outlying areas without electricity, due to the impermanence of some areas Changes in weather, it is easy to appear hail, in order to avoid
Hail causes to damage to solar battery plate surface, the executive component that people pass through hydraulic system --- and hydraulic cylinder controls solar energy
The deflection direction of solar panel mitigates hail to solar battery to change the incidence angle that hail is fallen on solar panel
The collision dynamics of plate.But in the case where ambient air temperature is low, hydraulic oil viscosity increases, or even the solidification of section hydraulic oil occurs
The phenomenon that, cause hydraulic cylinder charge oil pressure to reduce, the power consumption of hydraulic oil pump, which has to be larger than nominal situation several times, could remain hydraulic
Normal direction of rotation of the cylinder to solar panel, this is very big to the loss of hydraulic oil pump.
Summary of the invention
The technical problem to be solved by the present invention is to the defects for conventional cylinder, and it is an object of the present invention to provide a kind of polysilicon
Solar battery chip turns to carrying equipment, solves conventional cylinder and maintains normal fuel injection in low temperature environment and make
At the big problem of power consumption.
The present invention is achieved through the following technical solutions: a kind of polysilicon solar cell chip turns to carrying equipment,
Cylinder barrel including one end open and with the bolted cylinder cap in open end, the cylinder barrel side is provided with the first oil pipe and
Two oil pipes, piston rod, piston and guide sleeve are provided in cylinder barrel, and the activity of described piston rod one end runs through guide sleeve, cylinder cap and spiral shell
It tethers and is connected to export head, the other end of piston rod is through piston and flexible connection has buffer unit, and the piston both ends are respectively provided with
Have an annular piston pad, the outer diameter of the annular piston pad is equal to the internal diameter of cylinder barrel, the internal diameter of the annular piston pad along piston extremely
The both ends of cylinder barrel are gradually increased.
In part cold district, low temperature causes the hydraulic oil viscosity in hydraulic oil pump to increase, and adding can in hydraulic oil
Can there can be water, so that even will form solid in hydraulic oil, above-mentioned two situations all reduce the mobility of hydraulic oil, so that
Hydraulic oil flow rate is slow.It is hydraulic when the pressure that hydraulic oil pump is exported under normal operating condition makes hydraulic oil to piston effect
Oily slug flow speed, weak force are not enough to push piston proper motion, so that the output end operation irregularity of hydraulic cylinder.
To solve the above-mentioned problems, the present invention provides one kind can increase hydraulic oil to the double acting list of piston effect power
Hydraulic piston rod cylinder.
The present apparatus has cylinder barrel, the first oil pipe, the second oil pipe, piston, piston rod, guide sleeve, cylinder cap and export head, these
Device is all that traditional two-action single-rod hydraulic cylinder has.Unlike traditional hydraulic cylinder, the present apparatus is in work
The both ends of plug are provided with annular piston pad.The shape of annular piston pad is the cylindrical body for offering through-hole, and piston rod is sliding
Dynamic by the through-hole, the outer diameter of cylindrical body is equal to the internal diameter of cylinder barrel, the internal diameter of cylindrical body, i.e. the diameter of through-hole is variation,
Along from the one end being fixed on piston, to one end far from piston, the diameter of through-hole is gradually increased.Preferably, through-hole position
Diameter in that end on piston is equal to the diameter of piston rod, and the diameter of one end far from piston is equal to the internal diameter of cylinder barrel.It is above-mentioned
Through-hole diameter be gradually increased including at least two kinds of situations, the first situation is that through-hole is cone, from being parallel in cylinder barrel
It is seen on the section of axis, through-hole is isosceles trapezoid；In second situation, from the section for being parallel to cylinder barrel central axes, through-hole
For hemisphere.
When hydraulic oil is close to piston, along piston to the direction at cylinder barrel both ends, hydraulic oil is divided into several segments.Wherein first
Section and piston contact push piston motion, and second segment is pushed first segment by the promotion of third section, and first segment is by piston
Reaction force while also to second segment transmit a reaction force.Traditional hydraulic cylinder, only with the piston of cylindrical body, circle
The piston both ends of cylinder and the contact surface of hydraulic oil are plane.When first segment hydraulic oil acts perpendicularly to piston, it is subject to
Reaction force is vertically second segment hydraulic oil, correspondingly, second segment hydraulic oil vertically reacts on third section hydraulic oil,
And so on.Allow in this way third section hydraulic oil need to provide bigger power can just overcome second segment hydraulic oil to reaction
Power.It it can be concluded that, is the piston of plane for contact surface by foregoing description, hydraulic oil pump is needed when providing output pressure
So that the reaction force that hydraulic oil overcomes piston vertical can push piston to move in cylinder barrel.Improved hydraulic cylinder is then in work
Annular piston pad is increased beyond the Great Wall, when first segment hydraulic oil acts perpendicularly on the side wall of the through-hole of annular piston pad, annular
Piston pad is no longer perpendicular to first segment hydraulic oil to the reaction force of first segment hydraulic oil, and is perpendicular to the method for side wall curved surface
Line, and this power is parallel to the axial component of cylinder barrel certainly less than resultant force, institute along the direction perpendicular to first segment hydraulic oil
The reaction force that piston sends first segment hydraulic oil to is significantly reduced with annular piston pad, so that hydraulic oil pump is same
When output pressure, the reaction force that piston is given is reduced, and piston is easier to move in cylinder barrel；Moreover, when annular piston pad
It acts on and is parallel to the component of cylinder barrel radial direction to longitudinal component of the reaction force of first segment hydraulic oil and makes first segment hydraulic oil
Squeezed to the central axes of through-hole, the effect generated in this way is, along annular piston pad through-hole wall surface to through-hole central axes direction,
The power that hydraulic oil acts on annular piston pad is gradually increased from edge to centre, since contact area is gradually reduced, central axes
The hydraulic oil at place also increases with it the pressure of annular piston pad, so that movement of the piston in cylinder barrel is more easier.
In conclusion changing piston to the reaction force direction of hydraulic oil, to reduce liquid by annular piston pad
Pressure oil pump output terminal needs the reaction force from piston overcome, so that movement of the piston in cylinder barrel is more smooth, effectively
Ground reduces the output power consumption of hydraulic oil pump.In low temperature environment, even if there is the phenomenon that flow velocity is slow, partially solidified and leads in hydraulic oil
It causes the active force for acting on piston small, hydraulic oil pump can also allow that not increase excessive power consumption, providing stronger output pressure
Under the premise of work normally the present apparatus.
In addition, finding in practical applications, the closed end of cylinder barrel is fixed on the pedestal of solar panel, cylinder barrel
Open end straight up, when piston rod down, i.e., when mobile to closed end, piston rod can be collided suddenly to the closed end of cylinder barrel
On.The damage of piston rod is not only resulted in this way, while also resulting in the vibration by lifting device that export head is connected, seriously
When can also damage the device.It generates there are two this phenomenon reasons, first in low temperature environment in hydraulic oil the reason is that because wrap
Containing solid, so that hydraulic oil is no longer successional fluid, flowing no longer has continuity, when hydraulic oil is from the second oil pipe
In when taking away, if the solid in hydraulic oil is pumped, due to poor continuity between solid and liquid, in hydraulic oil just
It will form one piece of gap for being equal to the solid volume, which flow the hydraulic oil of surrounding into this gap suddenly, loses
The support to piston rod has been gone, has slid one section down suddenly so as to cause piston rod；Second the reason is that piston rod supported
There is the object that export head is connected gravity to be born along with the gravity of piston rod positioned at the hydraulic oil of piston lower portion
Active force is very big, correspondingly, requiring just height to the mobility of hydraulic oil, answers since it is desired that being changed in it by the deformation of hydraulic oil
Power slows down the pressure that annular piston pad, piston, piston rod are transmitted to reaching, enable piston rod slowly, smoothly under
It moves, when the temperature is low, running of hydraulic power oil is poor, corresponding deformation can not be generated, so that the folding process of piston rod is easy to appear
Decline suddenly.To solve the above-mentioned problems, piston rod has buffer unit towards one end flexible connection of cylinder barrel closed end.Here it mentions
To flexible connection refer to and allow connecting portion that axial stretching occurs, along the axial connection type for generating certain displacement amount, here
The elastomeric joints such as bellows can be used in the mode of the connection used.By the buffer unit of flexible connection, when piston rod is hit suddenly
When hitting cylinder barrel bottom, the bottom of buffer unit is impinged upon first on the closed end of cylinder barrel, and cylinder barrel is passed to buffering by buffer unit
Piston rod is passed to after the reaction force attenuation of bottom of device, piston rod continues to move a distance to buffer unit, while soft
Property connection shrink, by this section of mobile distance, the impulse force that is not only subject to piston rod is reduced, but also it is direct to avoid piston rod
It is collided with cylinder barrel closed end, moreover, buffer unit replaces section hydraulic oil, plays certain undertaking to piston rod and makees
With moving down piston rod gently.
Further, buffer unit includes the shell of one end open, and spring, the bullet are provided on the closed termination of outer cover
Towards being connected with buffer stopper on one end of shell aperture, the buffer stopper and piston rod match spring.The buffer unit is
Cylinder, the cylinder one end open other end are closed, and spring is fixed on closed end, and the other end of spring connects buffer stopper.Buffer stopper
Match with piston rod and mean, size and the piston rod of buffer stopper match, after piston rod enters shell, with buffer stopper
Contact, the two is relatively fixed while moving inside the shell.
Further, the central axes of cylinder barrel, piston rod, piston, buffer unit and annular piston pad overlap.It sets in this way
It sets and enables to being more uniformly stressed for piston, while piston rod will not occur to make power due to bias and cause to be broken in output
The case where.
Further, pin hole is provided in export head.Pin hole can be set in export head, sold by being inserted into pin hole
Export head is fixed together by axis with the device gone up and down is needed.
Further, external screw thread is provided in export head.External screw thread can be set in export head, by export head with need to rise
