Described batteries is that 80 storage batterys are divided into two groups, is contacted mutually by 40 storage batterys for every group and forms, and parallel with one another between two groups, two group storage batteries are installed in the both sides of workover rig respectively.
The beneficial effects of the utility model: the control device that the utility model workover rig batteries discharges and recharges, the information that main control box is come current of electric and foreign current feedback information to charging-discharging controller is comprehensively judged, determine the target current size, again this information is sent to charging-discharging controller, carry out after receiving information by charging-discharging controller, realize discharging and recharging batteries.The utility model carries out management of charging and discharging to batteries, has prolonged the useful life of batteries, has improved the utilance of batteries, has ensured the cruising of workover rig or has played the lower tubular column operation.
Description of drawings
Fig. 1 is the control device structural representation that the utility model workover rig batteries discharges and recharges.
Among the figure, 1-operation control, 2-main control box, 3-battery charge and discharge device, 4-inverter, 5-motor, 6-silicon controlled rectifier, 7-power controling box, 8-external ac power source, 9-batteries.
Embodiment
Embodiment 1: the control device that discharges and recharges with a workover rig batteries is an example, and the utility model is described in further detail.
Consult Fig. 1.The control device that the utility model workover rig batteries discharges and recharges, mainly form, operation control 1 is arranged at the workover rig driver's cabin by operation control 1, main control box 2, battery charge and discharge device 3, inverter 4, motor 5, silicon controlled rectifier 6, power controling box 7, external ac power source 8 and batteries 9.Adopt holding wire to interconnect between operation control 1 and the main control box 2; Adopt holding wire to interconnect between main control box 2 and the battery charge and discharge device 3; Adopt holding wire to interconnect between motor 5 and the main control box 2; Adopt holding wire to interconnect between main control box 2 and the silicon controlled rectifier 6; Interconnect by cable between motor 5 and the inverter 4; Interconnect by cable between inverter 4 and the battery charge and discharge device 3; Interconnect by cable between battery charge and discharge device 3 and the silicon controlled rectifier 6; Interconnect by cable between silicon controlled rectifier 6 and the power controling box 7; Interconnect by cable between battery charge and discharge device 3 and the power controling box 7; Interconnect by cable between power controling box 7 and the batteries 9, power controling box 7 connects 380V external ac power source 8.Batteries 9 is that 80 storage batterys are divided into two groups, is contacted mutually by 40 storage batterys for every group and forms, and parallel with one another between two groups, two group storage batteries are installed in the both sides of workover rig respectively.
The principle of the control device that summary workover rig batteries discharges and recharges.Consult Fig. 1.When workover rig will be realized a certain operation, by operation control 1 this information (requirement of target motor 5 rotating speeds) is passed to main control box 2, main control box 2 sends to charging-discharging controller 3 with this information again, charging-discharging controller 3 is given main control box 2 with current of electric and foreign current feedback information, motor 5 also feeds back to rotary speed information main control box 2 simultaneously, main control box 2 is comprehensively judged the information that the two passes over, determine the target current size, again this information is sent to battery charge and discharge device 3, battery charge and discharge device 3 begins to carry out after receiving information, realizes discharging and recharging batteries.
