Abstract
The utility model provides a super low frequency controllable focus device in order to solve the defect that continuous work time of the controllable focus is short at present. The utility model is characterized in that two vibrators, a counterweight box and an electric machine are arranged on a vertical surface which is overlapped with the central shaft line of the long shaft of the bottom board and are connected with the complete machine into a whole. When the electric machine rotates, the eccentric wheels of the two vibrators rotate relatively to drive the complete machine to move upwards and downwards and back and forth, then hundreds of hours of continuous vibration can be realized. The magnitude of the vibrational frequency and the vibrational force can be regulated through a power distribution control system and weight magnitude of the counterweight material arranged in the counterweight box to adapt to the need of petroleum production with vibration method.
Description
The utility model is a kind of ultralow frequency controlled source technology, and it can be applicable to, and artificial earthquake is surveyed, seismic model experiment, is specially adapted to the vibratory drilling method oil exploitation in oil field.
The MERTZ M18HD/612 type controlled source that american wheat sesame company (MERTZ INC) makes is state-of-the-art in the world at present technology, and it is to promote slide block by hydraulic mechanism to pump, thereby drives the complete machine up-down vibration.Because the about 4 tons of weights of vibration weight of this machine, vibration frequency 5-250 hertz when long time continuous working, can make fluid temperature in the hydraulic mechanism raise and causes the frequency shakiness, clearly provides each sustained vibration time in its manual to be no more than 30 seconds.
But the purpose of this utility model is the ultralow frequency controllable focus device that provides hundreds of hours shaking force of a kind of continuous operation bigger to can be used for the vibratory drilling method oil exploitation in oil field, can significantly improve the output of oil.
The purpose of this utility model is achieved in that base plate and cement base is fixed as one with fang bolt, puts two oscillators on the axis of base plate long axis direction, and is connected with bolt and base plate.Motor, counterweight bar and uncovered ballast box are housed above framework, and the center of gravity of oscillator, motor and ballast box is on the vertical plane that the axis with the base plate major axis coincides.When motor rotates, the eccentric wheel of two oscillators is rotation relatively to the inside, thereby the drive complete machine pumps and realizes vibration, regulate the size of vibration frequency simultaneously by power distribution control system (prior art), the size of its vibration force can be regulated and control within the specific limits by the size of the weight material of putting in the metal weights case (metal, cement products or other) weight, to adapt to different needs.
Below with reference to accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the elevation of power transmission shaft and oscillator.
Fig. 3 is the oscillator sectional side view of Fig. 2 along A-A '.
Power transmission shaft shown in Figure 2 and oscillator are by driven pulley (15), the support of bearing (8), universal joint (17), and change-speed gearing (18) and oscillator (5) are formed.
Oscillator shown in Figure 3 is made up of eccentric wheel (16), change-speed gearing (18), oscillator case (19) and bearing (20).
With reference to Fig. 1-3, base plate (13) and cement base (12) are fixed as one with fang bolt.On the axis of the long axis direction of base plate (13), adorn two oscillators (5) at a distance of 1.5-3.0 rice, and with bolt and base plate (13) binding.The support of bearing (8) is fixing with bolt and base plate (13), and power transmission shaft (11) is connected with oscillator (5) by the gearbox (6) at the support of bearing (8) and two ends.Motor (14) is installed in the middle of on the crossbeam (3) of framework, the both sides of motor (14) are two ballast boxes (1), the front and back of motor (14) are two set of weights bars (2), and motor (14), ballast box (1) and oscillator (5) are on the vertical plane that the axis with base plate (13) major axis coincides.Framework is made of column (4), cant beam (7) and crossbeam (3), and weld mutually with base plate (13) and crossbeam (3) respectively at the two ends of its column (4) and cant beam (7).Belt (10) is looped around on driving wheel (9) and the driven pulley (15), and when motor (14) rotated, the eccentric wheel (16) that drives in the oscillator (5) by transmission mechanism rotated to the inside relatively, complete machine is pumped realize vibration.Regulate the size of vibration frequency by the power distribution control system that is connected with motor (14).
Claims (3)
1, a kind of ultralow frequency controllable focus device of being made up of base, base plate, framework, oscillator, counterweight bar, ballast box, power transmission shaft, gearbox and the motor that is connected with power distribution control system is characterized in that the oscillator that is connected with base plate and the center of gravity of the ballast box that is connected with framework and motor is on the vertical plane that the axis with the base plate major axis coincides.
2, ultralow frequency controllable focus device according to claim 1 is characterized in that the power transmission shaft two ends are connected with two oscillators respectively by gearbox.
