Description
(1) technical field
The present invention relates to a kind of Full automatic bus lift frame hydraulic systems, relate in particular to a kind of effectively reduction oil return
The busbar lift frame hydraulic system of back pressure.
(2) background technology
In busbar lift frame, the release of small box fastener and tighten be the key that aluminum electrolysis industry lift busbar operation when behaviour
Make, traditional lift busbar operation is needed people and completed the release of small box fastener using special spanner and tightened by manual operation.But
Manual operation can cause problems with：1. manually unclamp and tighten small box fastener, operator need to stand on the cell cover plate of high temperature
Operation, the personnel of easily causing damage or scald accident；2. small box fastener unclamps, not in place or screw-down torque is insufficient, and damage equipment is hindered
And the person；3. needing several personnel's cooperations when operation, efficiency is low, of high cost, the operating time is long；If 4. easily leading to explosion when maloperation
Etc. serious accidents.
For this purpose, now generally using the busbar lift frame with pneumatic system or hydraulic system, the pneumatic system
Or capsule will be unclamped and tightened to hydraulic system for full-automatic anode busbar jacking frame when aluminum electrolysis industry lifts busbar operation
The function of fixture is integrated on busbar lift frame.Passed through by hydraulic pump as power source using the lift frame of hydraulic system
The bidirectional rotation of reversal valve indirect control hydraulic motor.Hydraulic pump is driven to provide high pressure by shaft coupling by motor when system works
Oil realizes that it is small that the bidirectional rotation of hydraulic torque wrench is then realized by reversal valve to control the forward or reverse of hydraulic motor
Box fixture is tightened and is unclamped.But since the pressure fluctuation range of hydraulic pump pumping is larger, control is inaccurate, is easy to make
It is changed greatly at the torque of hydraulic torque wrench, it is inaccurate, exist and unclamp the insufficient problem of not in place or screw-down torque, makes
At safety accident.
Such as in CN203999849U, a kind of busbar lifting frame structure, including busbar lift frame ontology are disclosed,
The both sides of the busbar lift frame ontology have symmetrically been uniformly arranged a series of holding fixture, are set on the outside of the holding fixture
It is equipped with stubborn head device corresponding with the screw rod of small box fastener, the stubborn head device includes being fixed to hold fixture side tightly
Drive motor exports the transmission shaft of axis connection with drive motor and the stubborn head in end part of driving shaft is arranged, and the stubborn head turns
Axis outer sheath is equipped with guideway, and the guideway is arranged by support plate in the side for holding fixture tightly.Main is exactly to adopt
Hydraulic pressure or pneumatic actuation twist head, then it is inaccurate to be primarily present control, be easy to cause the torque of hydraulic torque wrench
It changes greatly, it is inaccurate, exist and unclamps the insufficient problem of not in place or screw-down torque.
For another example in CN204849060U, discloses a kind of full-automatic fastening device of busbar lift frame and busbar promotes dress
It sets, including frame, which is equipped with hydraulic power unit and several groups anode rod fixture；On each anode rod fixture
Small box clamp, a wrench device above small box clamp equipped with one for clamping anode rod；Wrench device includes solid
Lifting cylinder on anode rod fixture, the hydraulic motor being fixedly arranged on the piston rod of lifting cylinder, by an adapter
The spanner being fixedly connected with the drive shaft of hydraulic motor；Hydraulic power unit includes at least two hydraulic power unit and liquid
The oil pressure pipe of press pump station connection；Hydraulic power unit is connect by the oil pressure pipe with hydraulic motor, is carried for the driving of hydraulic motor
For power；The automation control of hydraulic power unit is operated by control device.
In such hydraulic system, it is primarily present problems with：(1) there is the torque for be easy to causeing hydraulic torque wrench
Size variation is larger, inaccurate problem, the torque for tightening or unclamping small box fastener cannot accurately be set or adjusted, sternly
Ghost image rings the safety in production process；(2) additionally there are motor start and stop moments injures failure to the recoil of hydraulic pump, usually deposits
In the too high knotty problem for causing hydraulic motor axle envelope to be rushed to open of return oil pressure；(3) in addition during startup, traditional is
System design is not energy-saving and environment-friendly, and does not meet energy-saving and emission-reduction theory so that the startup load of whole system is very big, waste of energy；
(4) and along with the use of equipment, the cleannes of fluid can gradually decline, and cause component to wear so that whole system is not
Stablize；(5) entire system is not integrated enough, intelligent.This programme can then promote product intelligent operability, visualize journey
Degree higher, and each element arrangement is more compact, pipeline arrangement is got up more succinct, beautiful, reasonable；Also in actual system, all
Be meet it is above-mentioned it is basic using function under the premise of, can not make that the design of hydraulic system is safer, more perfect, more human nature
Change.
