Description
(1) technical field
The present invention relates to a kind of full-automatic anode busbar jacking frame hydraulic systems, relate in particular to a kind of return pressure
The full-automatic anode busbar jacking frame hydraulic system that low achievable zero load starts.
(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

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：It is big in the presence of the torque for be easy to causeing hydraulic torque wrench
The torque for tightening or unclamping small box fastener cannot be accurately set or adjusted, seriously in small to change greatly, inaccurate problem
Influence the safety in production process；Additionally there are motor start and stop moments to injure failure to the recoil of hydraulic pump, usually exists back
The too high knotty problem for causing hydraulic motor axle envelope to be rushed to open of oily back pressure；In addition during startup, the design of traditional system
It is not energy-saving and environment-friendly, does not meet energy-saving and emission-reduction theory so that the startup load of whole system is very big, waste of energy；And companion
With the use of equipment, the cleannes of fluid can gradually decline, and cause component to wear so that whole system is unstable；Entirely
System it is not integrated enough, intelligent, this programme can then promote product intelligent operability, visualization higher, and each
Element arrangement is more compact, and pipeline arrangement is got up more succinct, beautiful, reasonable；Also in actual system, be all meet it is above-mentioned
Using under the premise of function, the design of hydraulic system can not be made safer, more perfect, more humane substantially.
