(3) summary of the invention:
The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and provide a kind of drill string that can reclaim to transfer the potential energy that discharges, the oil-well rig power reclaiming type brake system of minimizing system heating, mainly solve existing oil-well rig brake system and transfer the potential energy that discharges so that the drill string of recovery to be arranged, potential energy can only be become thermal energy consumption and fall, increase the problem of whole system heating simultaneously.
In order to achieve the above object, the utility model is achieved in that oil-well rig power reclaiming type brake system, it comprises cylinder 23, one end is connected with prime mover 18 by clutch 22, transmission mechanism 21, steel cable on the cylinder 23 is connected with hook 20 by assembly pulley 19, its special character is that the other end of cylinder 23 is connected with Power Recovery type auxiliary brake, and Power Recovery type auxiliary brake comprises clutch 17, reducer 16, variable pump-motor 9, choke valve 8, accumulator, two-position two-way solenoid valve 13, overflow valve 14; Establish service brake system on cylinder 23, service brake system comprises disk type brake 12, two-position three way magnetic valve 11, brake valve 10; Establish hydraulic pump 2 on pipeline, hydraulic pump 2 is connected with oil filter 1, and hydraulic pump 2 is connected with service brake system, Power Recovery type auxiliary brake and power tongs oil motor loop respectively by one way valve 3.
In order further to realize above-mentioned purpose, oil-well rig of the present utility model power reclaiming type brake system, its described power tongs oil motor loop is made up of 3-position 4-way electro-hydraulic reversing valve 4, choke valve 5 and two-way hydraulic motor 6, connect oil filter 24 9 times at described variable pump-motor, described service brake system can be a disk type brake, also can be band brake, described accumulator comprises energy storage piston rod 15, nitrogen bag 7.
Oil-well rig described in the utility model with power reclaiming type brake system compared with the prior art, have substantive distinguishing features and progress: owing in system, adopt Power Recovery type auxiliary brake, it is except providing moment of resistance control drill string lowering velocity, can also reclaim drill string and transfer potential energy and the utilization again that discharges, both save the energy, reduced energy waste, reduce the heating of whole system again, prolonged the life-span of component in the system.
(4) description of drawings:
Fig. 1---structural representation of the present utility model.
(5) specific embodiment:
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe the utility model oil-well rig power reclaiming type brake system in detail.
Oil-well rig described in the utility model is with power reclaiming type brake system, and when hoisting drill string, clutch 22 engages, and prime mover drives the cylinder rotation by transmission mechanism, thereby drives the hook drill string that hoists by assembly pulley.When transferring drill string, clutch 22 separates, drill string is under the effect of weight own, by putting into well under the rotation of assembly pulley drive cylinder, the moment that this moment, drill string weight acted on the cylinder is active moment, in order to control the speed that drill string is transferred, need to add the moment of resistance on cylinder, this moment of resistance is provided by variable pump-motor, and the characteristics of variable pump-motor are to be the pump operating mode, also can be the motor operating mode, this moment, variable pump-motor was the running of pump operating mode, and the moment of resistance is provided, and is simultaneously oil-filled to accumulator, the potential energy that is about to drill string is converted into hydraulic pressure and can be stored in the accumulator, thereby realizes that energy reclaims.Regulate choke valve and can regulate the speed that drill string is transferred.Because the drill string weight of transferring at the beginning is little, at this moment access power reclaiming type auxiliary brake not, two two electromagnetic valves can be placed left side position, clutch 17 is separated, this moment by hydraulic pump to main brake, power tongs oil motor loop and promote empty elevator required energy is provided.When the weight of transferring drill string is increased to a certain degree, but access power reclaiming type auxiliary brake, two two electromagnetic valves are placed right position, clutch 17 is engaged, this moment is when transferring drill string, oil-filled in accumulator, the energy in the accumulator can be used for main brake, power tongs oil motor loop and promotes empty elevator required energy is provided, and can quit work hydraulic pump this moment.In addition in transferring the drill string operation, after the length that drill string is transferred a thribble enters in the well, need check drill string and connect another root again, at this moment the outlet oil pressure of brake valve can be turned down, disk type brake is braked under the effect of spring force, connect drill string after, transfer the outlet oil pressure of brake valve big, oil in the accumulator enters the disk type brake oil cylinder, overcomes spring force and declutches, and drill string is transferred; After the length that drill string is transferred a thribble enters in the well, has needed the lift-off elevator to go to put forward to connect another thribble, the oily entering variable pump-motor in the accumulator at this moment, variable pump-motor are the motor operating mode and drive cylinder and rotate, thus a lift-off elevator; Harness cord links and connects between thribble and drill string, and the 3-position 4-way electro-hydraulic reversing valve places a when position left side, the oil in the accumulator to enter two-way oil motor and drives on the power tongs and buckle, but shackle when the 3-position 4-way electro-hydraulic reversing valve places right position.When emergency episode takes place when, two-position three way magnetic valve is placed position, a left side, carry out snub, during normal operation, two-position three way magnetic valve is placed right position.
Oil-well rig described in the utility model also is applicable to the brake system of petroleum well servicing rig and tractor hoist with power reclaiming type brake system.
