Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
A kind of capacity-increasing type electric drive workover rig, as depicted in figs. 1 and 2, comprises automobile chassis 7; Also comprise the cylinder 6 be arranged on respectively on automobile chassis 7, motor 5 that supporting leg 8, derrick unit, driver element, control unit, head roll 6 rotate and the energy-storage units 3 that is connected with motor 5; Described driver element connects motor 5 and energy-storage units simultaneously; Described control unit connects driver element, energy-storage units 3 and motor 5 simultaneously.
Wherein, described driver element comprises engine block and mains supply module.
Wherein, the described engine block power takeoff 2 that comprises automobile engine, generator 1 and be connected with engine output end; Described power takeoff 2 drives generator 1 to generate electricity by power transmission shaft 4; Described generator 1 is electrically connected with energy-storage units 3 and motor 5 respectively.When using the motor driven on automobile chassis 7, by power takeoff 2 power taking, simplifying and having fallen original power transmission shaft, a series of mechanical transmission unit such as gearbox, torque converter.Greatly reduce equipment purchasing expense, decrease rigging up and debugging time and fault rate.
Wherein, described mains supply module comprises three-phase alternating current electrical interface and governor circuit; Described governor circuit is connection control unit, energy-storage units 3 and motor simultaneously.
Wherein, described supporting leg 8 comprises the support oil cylinder being connected with hydraulic lock, improves stability and the safety of complete machine.Reliable and stable during the work of this workover rig, safety is high.
Wherein, described derrick unit comprises hydraulic cylinder 12, is vertically arranged on the upright pylon 9 on automobile chassis 7 and the derrick 10 be folded on automobile chassis 7 and the hook 11 be arranged on derrick; Described hydraulic cylinder 12 one end is articulated with automobile chassis 7, and the other end is articulated with the bottom of derrick 10.The extension bar of hydraulic control cylinder 12 stretches out, and hydraulic cylinder supports derrick 10 and erects, and can dock and fix, namely can carry out operation with upright pylon 9.
Wherein, described control unit comprises frequency converter, control module and the detection module for detecting motor real work power; Described frequency converter connects driver element, energy-storage units 3 and motor 5 simultaneously.
It should be noted that, under using three phase network electric power thus supplied, when detection module detection of grid power is greater than the real output of motor 5, be transferred to control module signal, control mains supply module by control module and power section more than needed is charged to energy-storage units 3.And when carrying on cylinder 6, detection module detects that motor full power exports, now control mains supply module and energy-storage units simultaneously for motor 5 provides power demand by control module, motor 5 is operated at full capacity, lifting heavy.
In addition, under not using three phase network electric power thus supplied, when on detection module detection automobile chassis 7, engine output is greater than motor 5 power output, then give control module signal, controlling generator by control module is energy-storage units 3 energy storage.And when carrying on cylinder 6, detection module detects that motor 5 full power exports, now control generator 1 and energy-storage units 3 simultaneously for motor provides power demand by control module, motor is operated at full capacity, lifting heavy.
Wherein, described motor 5 is provided with brake gear.Electric tools is for brake function, and the floating state of cooperating equipment hook, considerably increases the safety factor of equipment.It should be noted that, after cylinder 6 proposes OIH pipe, during brake halted state and dependence self gravitation cylinder transfer hook, generator also can be controlled be energy-storage units accumulation of energy by control module, prepares to promote next time.
The concrete course of work of this capacity-increasing type electric drive workover rig workover rig is:
When workspace can provide three phase network to power, powered by the external three phase network of three-phase alternating current electrical interface of mains supply module, drive motor is also energy-storage units 3 energy storage.The time that energy-storage units 3 is greater than output power of motor at grid power carries out energy storage, and the full power carried on cylinder 6 is when exporting, be supplied to motor 5 together with the power that the power provided by extraneous electrical network and energy-storage units 3 store, motor 5 operated at full capacity, lifting heavy.When using extraneous electrical network, automobile chassis 7 can stop working, and both saves energy consumption, and additionally reduces machine running times, and decreased maintaining time and oil pollution.
When the external world does not have three phase network, use the motor driven small power generator 1 of automobile chassis 7 to energy-storage units 3 energy storage (as long as the engine output of automobile chassis 7 is greater than output power of motor energy-storage units just carry out energy storage).Cylinder 6 is carried generator 1 and energy-storage units 3 in process and provides power simultaneously, motor 5 is operated at full capacity, lifting heavy.For power stage at full capacity, the engine output of automobile chassis can drop to 50% of existing equipment at most, greatly reduces the expense of equipment purchasing, also reduces oil consumption simultaneously.
The utility model profit (namely uses extraneous electrical network and energy-storage units in two ways; Or with automobile chassis power takeoff generator and energy-storage units) drive motor 5 drives cylinder 6 to rotate, and replace original simple chassis power taking mechanical conveyor and move cylinder and rotate.Power drive mode does not limit by field condition, low in energy consumption, and safety is high, convenient and reliable operation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
