Description
Technical field:
The present invention relates to a kind of plant equipment that is used for the oilfield oil well workover treatment.
Background technology:
In oil-water well well workover and underground work process, needs use the operation tractor hoist that the OIH pipe is promoted to ground or oil pipe are transferred in the well, finally reach the construction purpose by the oil pipe rountrip.At present, the on-the-spot tractor hoist that uses has two types, and a kind of tractor hoist adopts Diesel engine to drive, another kind of tractor hoist is that ac variable-frequency electric motor drives, and the former shortcoming is to need to consume a large amount of diesel oil, and energy utilization rate is low, the maintenance cost height, and can not frequent starting when being interrupted work; The latter's shortcoming then is the restriction that is subjected to the job site power supply capacity, and security performance is relatively poor.
Summary of the invention:
The object of the present invention is to provide a kind of can save energy and reduce the cost, improve energy utilization rate and can not frequent starting can overcome the work of Diesel engine formula tractor hoist interruption the time and high voltage source frequency conversion tractor hoist be subjected to the tractor hoist with speed adjusted by super capacitance set storage type generator of shortcoming and defect such as power supply capacity restriction.
Above-mentioned purpose of the present invention is to realize like this.This kind operation tractor hoist is made up of 380V three-phase alternating-current supply air switch, charge power supply module, capacitance set storage device, DC speed regulation module, control panel, main motor, shaft coupling, gearbox, power drive system, winch clutch, winch, auxiliary brake clutch, directional overrunning clutch, auxiliary brake direct current generator, charger, accumulator, end truck system, hydraulic system, derrick system, air switch input and oil pumper 380V three-phase alternating current external power supply join, and output links to each other with the charge power supply module; The other end of charge power supply module links to each other with the capacitance set storage device, and the capacitance set storage device links to each other with DC speed regulation module by current limiter, and the DC speed regulation module output links to each other with main motor with control panel respectively; Main motor links to each other with the winch clutch of winch one end by shaft coupling, gearbox, power drive system; The winch other end is provided with the auxiliary brake system that is made of auxiliary brake clutch, directional overrunning clutch, auxiliary brake direct current generator, charger, accumulator, wherein, auxiliary brake clutch, directional overrunning clutch link to each other with winch successively, directional overrunning clutch links to each other with the auxiliary brake direct current generator, and auxiliary brake direct current generator, charger, accumulator link to each other successively; Above-mentioned each parts are provided with respectively, are installed on the end truck system, and hydraulic system and derrick system also are installed on the end truck system.
The course of work of this kind electric machine speed regulation tractor hoist is as follows: when oil well plays the pipe construction operation, at first the 380V three-phase alternating-current supply is received the incoming end of power supply air switch, the clutch of throwing off auxiliary brake, the power load that can drive according to the power supply of oil pumper, set the maximum value of charge power supply module input current, determine the gear of gearbox according to the payload in the construction operation and hoisting velocity, charging was started working in 5-10 minute more earlier before work.When promoting oil pipe, the electric current of main motor is made up of two parts, a part is that the charge power supply module is that direct current is supplied with main motor with the source current rectification, another part be power module capacitance set storage device to the required electric current of main motor replenish (when main motor electricity consumption hour, required electric current is directly provided by the charge power supply module, and the capacitance set storage device does not provide).The charge power supply module becomes the three-phase alternating current electric rectification direct current and gives the charging of capacitance set storage device, the electric energy of capacitance set storage device flows to DC speed regulation module by current limiter, under the control of DC speed regulation module, give main motor power supply, main motor is under the supply of this two parts electric current, the gear unit and the winch clutch that constitute by shaft coupling, gearbox, power drive system drive the winch rotation, winch pulling wire rope is realized construction operation by derrick system improving oil pipes such as overhead traveling crane, tourist buses.When rising stops and down during drain line, winch clutch is thrown off, main motor does not rotate, and when the required electric current of main motor during less than the maximum value of charging current module input current, source current obtains feedback signal by the charge power supply module and charges automatically; When the accumulation of energy of capacitance set storage device electric energy during to maximum value the charge power supply module obtain feedback signal and stop charging automatically.When construction operation under the down-hole during drain line, lifting force is very little, transfers brake force and strengthens, and needs to use auxiliary brake, when using auxiliary brake, the auxiliary brake clutch is engaged; On when carrying oil pipe, main motor is rotated by the electric energy that charge power supply module and capacitance set storage device provide, main motor just changes by gearbox, transmission system, winch clutch drive winch, when winch is just changeing, directional overrunning clutch is thrown off automatically, the auxiliary brake direct current generator does not rotate, and carries oil pipe in the realization; When transferring, main motor does not rotate, winch clutch is thrown off, winch reverses under the effect of deadweights such as tourist bus, oil pipe, winch drives the auxiliary brake clutch, thereby directional overrunning clutch drives rotation of auxiliary brake motor and generating, charge to accumulator by charger, realize the accumulation of energy auxiliary braking, last main brake and auxiliary brake are braked simultaneously and are realized brake and stop dead.
The present invention is reasonable in design, and is easy to operate, and reliable operation utilizes it to save energy and reduce the cost, and improves energy utilization rate greatly, avoids because of being interrupted the infringement to electrical network of pulsating current that electricity consumption causes.This kind tractor hoist adopts main motor stepless speed regulation to combine with mechanical speed change, makes the output torque scope increase, and the range of speeds broadens, and can satisfy the needs of different operating mode construction operations.Because the winch position has increased an auxiliary brake system, thereby part kinetic energy can be converted into electric energy, reduce energy consumption, and can alleviate main brake brake force, prolong the working life of main brake.
