Description
Technical field
The present invention relates to a kind of hydraulic cylinder, the turned to lift-launch being specifically related to a kind of polysilicon solar cell chip sets
Standby.
Background technology
Solar energy refers to the infrared radiant energy of the sun, is a kind of Renewable resource, and the amount of having is big, harmless, generally etc. many excellent
Point.The history of human use's solar energy can trace back to people in ancient times and utilize sun article, makes food etc..Now people
Demand to solar energy is the most no longer merely to utilize the heat energy of the sun.1615, France's engineer's Cox invented the world
The electromotor of upper First Driven by Solar Energy, open solar energy in modern age utilizes history.
Solar panel refers to solar radiant energy by direct or indirect the turning of photoelectric effect or Photochemical effects
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, in addition to above-mentioned field, solar panel be also used in remote segment areas without electricity such as plateau,
The local household electricity provided for the army and the people such as pastoral area or frontier sentry.
When being applied to outlying areas without electricity, owing to some areas Changes in weather is variable, hail easily occurs, in order to avoid
Damage is caused in solar panel surface by hail, and people control solar energy by the executive component hydraulic cylinder of hydraulic system
The yawing moment of cell panel, thus change the angle of incidence that hail falls on solar panel, alleviate hail to solaode
The collision dynamics of plate.But, in the case of temperature is low around, hydraulic oil viscosity increases, and even occurs that section hydraulic oil solidifies
Phenomenon, cause hydraulic cylinder charge oil pressure to reduce, the power consumption of hydraulic oil pump have to be larger than nominal situation several times could maintain hydraulic pressure
The cylinder normal direction of rotation to solar panel, this is the biggest to the loss of hydraulic oil pump.
Summary of the invention
The technical problem to be solved is the defect for conventional cylinder, it is therefore intended that provide a kind of polysilicon
The turned to carrying equipment of solar battery chip, solves conventional cylinder and makes to maintain normal fuel injection in low temperature environment
The big problem of power consumption become.
The present invention is achieved through the following technical solutions: the turned to carrying equipment of a kind of polysilicon solar cell chip,
Including cylinder barrel and the cylinder cap bolted with open end of one end open, described cylinder barrel side is provided with the first oil pipe and
Two oil pipes, are provided with piston rod, piston and fairlead in cylinder barrel, described piston rod one end activity runs through fairlead, cylinder cap and spiral shell
Tethering and be connected to delivery, the other end of piston rod runs through piston and has flexibly connected buffer unit, and described piston two ends are respectively provided with
Having annular piston pad, the external diameter of described annular piston pad is equal to the internal diameter of cylinder barrel, and the internal diameter of described annular piston pad is along piston extremely
The two ends of cylinder barrel are gradually increased.
At part cold district, low temperature causes the hydraulic oil viscosity in hydraulic oil pump to increase, and adding can in hydraulic oil
Can there is water so that even can form solid in hydraulic oil, above-mentioned two situations all reduce the mobility of hydraulic oil so that
Hydraulic oil flow velocity is slow.When the pressure that hydraulic oil pump is exported under normal operating mode makes hydraulic oil to piston effect, hydraulic pressure
Oil slug flow speed, weak force are all not enough to promote piston proper motion, so that the outfan operation irregularity of hydraulic cylinder.
In order to solve the problems referred to above, the invention provides a kind of can increase the hydraulic oil double acting list to piston active force
Hydraulic piston rod cylinder.
This device has cylinder barrel, the first oil pipe, the second oil pipe, piston, piston rod, fairlead, cylinder cap and delivery, these
The two-action single-rod hydraulic cylinder that device is all traditional is possessed.Unlike traditional hydraulic cylinder, this device is being lived
The two ends of plug are provided with annular piston pad.Annular piston pad be shaped as a cylinder offering through hole, piston rod is sliding
Dynamic by described through hole, cylindrical external diameter is equal to the internal diameter of cylinder barrel, and the diameter of cylindrical internal diameter, i.e. through hole is change,
Along from the one end being fixed on piston to the one end away from piston, the diameter of through hole is gradually increased.Preferably, through hole position
The diameter of that end on piston is equal to the diameter of piston rod, away from the diameter of one end of piston equal to the internal diameter of cylinder barrel.Above-mentioned
Through-hole diameter be gradually increased and at least include two kinds of situations, the first situation be through hole be cone, from being parallel to cylinder barrel
Seeing on the cross section of axis, through hole is isosceles trapezoid；In the second situation, from the cross section being parallel to cylinder barrel axis, through hole
For hemisphere.
When hydraulic oil is near piston, along piston to the direction at cylinder barrel two ends, hydraulic oil is divided into some sections.Wherein first
Section and piston contact, promote piston movement, and second segment is by the promotion of the 3rd section thus promotes first paragraph, and first paragraph is by piston
Counteracting force while also to second segment transmit a counteracting force.Traditional hydraulic cylinder, only has cylindrical piston, circle
The piston two ends of cylinder and the contact surface of hydraulic oil are plane.When first paragraph hydraulic oil acts perpendicularly to piston, it is subject to
Counteracting force is vertically second segment hydraulic oil, and accordingly, second segment hydraulic oil vertically reacts on the 3rd section of hydraulic oil,
The like.Thus make the 3rd section of hydraulic oil need to provide bigger power just can overcome second segment hydraulic oil to retroaction
Power.Can be drawn by foregoing description, be the piston of plane for contact surface, hydraulic oil pump, when providing output pressure, needs
Hydraulic oil is overcome, and counteracting force that piston is vertical can promote piston to move in cylinder barrel.Hydraulic cylinder after improvement is then being lived
Add annular piston pad beyond the Great Wall, when on the sidewall of the through hole that first paragraph hydraulic oil acts perpendicularly to annular piston pad, annular
Piston pad is no longer perpendicular to first paragraph hydraulic oil to the counteracting force of first paragraph hydraulic oil, and is perpendicular to the method for sidewall curved surface
Line, and this power is along being perpendicular to the direction of first paragraph hydraulic oil, is i.e. parallel to the axial component of cylinder barrel certainly less than making a concerted effort, institute
Significantly reduce piston with annular piston pad and send the counteracting force of first paragraph hydraulic oil to so that hydraulic oil pump is same
During output pressure, the counteracting force that piston is given reduces, and piston is easier to move in cylinder barrel；Moreover, when annular piston pad
Act on to longitudinal component of the counteracting force of first paragraph hydraulic oil, be i.e. parallel to cylinder barrel component radially and make first paragraph hydraulic oil
Extruding to the axis of through hole, so effect of generation is that annularly the through hole wall of piston pad is to the direction of through hole axis,
The power that hydraulic oil acts on annular piston pad is gradually increased to centre by edge, owing to contact area is gradually reduced, and axis
The pressure of annular piston pad is increased by the hydraulic oil at place the most therewith so that piston movement in cylinder barrel is more prone to.
In sum, by annular piston pad, change the piston counteracting force direction to hydraulic oil, thus reduce liquid
Pressure oil pump outfan needs the counteracting force from piston overcome so that piston movement in cylinder barrel is more smooth and easy, effectively
Reduce the output power consumption of hydraulic oil pump.In low temperature environment, even if flow velocity occurs in hydraulic oil, slow, partially solidified phenomenon is led
Cause to act on the active force of piston little, can also allow that hydraulic oil pump is not increasing too much power consumption, providing higher output pressure
On the premise of make this device normally work.
It addition, find in actual applications, the blind 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 blind end moves, piston rod can collide suddenly the blind end to cylinder barrel
On.So not only result in the damage of piston rod, also result in that delivery connected simultaneously by the vibration of lowering or hoisting gear, seriously
Time also can damage this device.Producing this phenomenon reason and have two, first reason is because in low temperature environment, wraps in hydraulic oil
Containing solid so that hydraulic oil is no longer successional fluid, its flowing no longer possesses seriality, when hydraulic oil is from the second oil pipe
In when taking away, if the solid in hydraulic oil is pumped, then due to poor continuity between solid and liquid, in hydraulic oil just
Can form one piece of space equal to this solid volume, this space makes the hydraulic oil of surrounding suddenly flow in this space, loses
Go the support to piston rod, thus result in piston rod the most down landing one section；Second reason is that piston rod supports
The object that delivery is connected has gravity, adds the gravity of piston rod, and the hydraulic oil being positioned at piston lower portion is to be born
Active force is very big, accordingly, requires the highest, since it is desired that change its planted agent by the deformation of hydraulic oil to the mobility of hydraulic oil
The pressure that power thus reach slows down annular piston pad, piston, piston rod are transmitted so that piston rod can slowly, smoothly under
Moving, when the temperature is low, running of hydraulic power oil is poor, it is impossible to produce corresponding deformation so that the folding process of piston rod easily occurs
Suddenly decline.In order to solve the problems referred to above, piston rod has flexibly connected buffer unit towards one end of cylinder barrel blind end.Here carry
To flexibly connect refer to allow connecting portion generation axial stretching, vertically produce certain displacement amount connected mode, here
The mode of the connection used can use the elastomeric joints such as corrugated tube.By the buffer unit flexibly connected, when piston rod hits suddenly
When hitting bottom cylinder barrel, first the bottom of buffer unit impinges upon on the blind end of cylinder barrel, and cylinder barrel is passed to buffering by buffer unit
Passing to piston rod after the reaction force attenuation of bottom of device, piston rod continues to move a segment distance to buffer unit, the most soft
Property connect shrink, by the distance of this section of movement, the impulse force not only making piston rod be subject to reduces, and it is direct to avoid piston rod
Colliding with cylinder barrel blind end, moreover, buffer unit replaces section hydraulic oil, serves certain undertaking to piston rod and makees
With, make piston rod gently move down.
Further, buffer unit includes the shell of one end open, and described closed termination of outer cover is provided with spring, described bullet
Spring faces out to connect on one end of shell opener has buffer stopper, described buffer stopper to match with piston rod.Described buffer unit is
Cylinder, the closing of the cylinder one end open other end, blind end is fixed with spring, the other end of spring connects buffer stopper.Buffer stopper
The meaning matched with piston rod is, the size of buffer stopper matches with piston rod, after piston rod enters shell, with buffer stopper
Contact, both are relatively fixed and move in the enclosure simultaneously.
Further, the axis of cylinder barrel, piston rod, piston, buffer unit and annular piston pad overlaps.So set
Putting and enable to being more uniformly stressed of piston, piston rod will not occur when output owing to bias makes power cause fracture simultaneously
Situation.
Further, delivery is provided with pin-and-hole.Pin-and-hole can be provided with, by inserting pin in pin-and-hole on delivery
Axle, is fixed together delivery with the device needing lifting.
Further, delivery is provided with external screw thread.External screw thread can be set on delivery, delivery is risen with needs
The device of fall is threaded connection.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the present invention passes through annular piston pad, changes the piston counteracting force direction to hydraulic oil, thus reduces hydraulic oil
Pump output terminal needs the counteracting force from piston overcome so that piston movement in cylinder barrel is more smooth and easy, effectively drops
The low output power consumption of hydraulic oil pump；In low temperature environment, even if hydraulic oil occurs that slow, the partially solidified phenomenon of flow velocity causes making
Little for the active force of piston, can also allow that hydraulic oil pump is not before increasing too much power consumption, providing higher output pressure
Put and make this device normally work；
2, the piston rod of the present invention has flexibly connected buffer unit, when piston rod clashes into bottom cylinder barrel suddenly, buffer unit
First bottom impinges upon on the blind end of cylinder barrel, and spring passes to after cylinder barrel is transmitted the reaction force attenuation bottom buffer unit
