Description
Technical Field
The invention belongs to the technical field of oilfield lifting processes, and relates to a speed reducer box body driving type oil pumping device for lifting crude oil in an oilfield development process.
Background
At present, in domestic oil pumping equipment, a plurality of lifting equipment for crude oil exploitation are adopted in a direct balance mode, and power transmission modes of the lifting equipment are different due to different structures, but the oil pumping equipment has a common characteristic: the power drive is connected with a speed reducing mechanism fixed on the bracket through a coupler or directly, the high-speed motion of the power is reduced to the low-speed motion through speed reduction, and then the power is transmitted to the driving roller to drive a flexible driving part connected with the roller to move, so that the pumping action is realized.
Disclosure of Invention
The invention aims to provide a speed reducer box body driving type oil pumping device which can simplify the structure of ground equipment, improve the stress condition of the equipment and provide power by means of rotation of a speed reducer box body.
The invention is composed of a motor, a coupling, a bearing support, a speed reducer, a driving turntable, a main shaft, a guide rail, a bracket, a flexible polished rod, a fastening pressing plate, a balancing flexible rope, a fixed pulley and a balancing box component;
the motor is connected with the coupler, the coupler is connected with the main shaft, the main shaft is connected with the speed reducer, the driving rotary table is installed at the central position outside the shell of the speed reducer, the main shaft is installed on the bearing support, the bearing support is connected with the support, the support is installed on the guide rail, the fixed pulley is installed at the rear end position of the support, the middle of the flexible polished rod is wound in a groove on the outer edge of the driving rotary table, one end of the flexible polished rod is fixed on the driving rotary table through the fastening pressing plate, one end of the balance flexible rope is connected with the driving rotary table, the balance flexible rope is installed on the fixed pulley in a hanging mode after bypassing.
The grooves on two sides of the driving turntable can be in a single-groove structure or a double-groove structure.
The diameter of the groove of the driving turntable can be larger than the diameter of the groove outside the speed reducer case body, and can also be the same as the diameter of the groove outside the speed reducer case body, and when the diameter of the groove of the driving turntable is equal to the diameter of the groove outside the speed reducer case body, the groove can be directly formed in the speed reducer case body.
Compared with the prior art, the invention has the following advantages:
the rotation of the speed reducer box body is utilized to directly provide power, so that a conventional driving roller is omitted, and equipment is simplified; the speed reducer can be integrally arranged on the central line of the support, so that the side turning force caused by the offset of the speed reducer is eliminated, the stress condition of the whole machine is improved, and the running is more stable.
Description of the drawings: FIG. 1 is a schematic diagram of the present invention; fig. 2 is a top view of fig. 1.
The specific implementation mode is as follows: the invention will be further described with reference to the accompanying drawings in which: the invention is composed of a motor 1, a coupling 2, a bearing support 3, a speed reducer 4, a driving turntable 5, a main shaft 6, a guide rail 7, a support 8, a flexible polished rod 9, a fastening pressing plate 10, a balancing flexible rope 11, a fixed pulley 12 and a balancing box 13; wherein motor 1 links to each other with shaft coupling 2, shaft coupling 2 links to each other with main shaft 6 again, main shaft 6 links to each other with speed reducer 4, drive carousel 5 is installed at 4 casing outside central points in the speed reducer and is put, main shaft 6 is installed on bearing support 3, bearing support 3 is connected with support 8, support 8 is installed on guide rail 7, fixed pulley 12 is installed in the rear end position of support 8, around in 5 outer edge ditch inslot of drive carousel in the middle of flexible polished rod 9, flexible polished rod 9 one end is fixed to drive carousel 5 through clamp plate 10, balanced flexible rope 11 one end is connected with drive carousel 5, hang after walking around the outer slot of 4 casings of speed reducer in the middle of balanced flexible rope 11 and install on fixed pulley 12, balanced flexible rope 11 other end is connected with balance box 13.
The grooves on both sides of the driving turntable 5 can be in a single-groove structure or a double-groove structure.
The diameter of the groove of the driving turntable 5 can be larger than that of the groove outside the box body of the speed reducer 4, and can also be the same as that of the groove outside the box body of the speed reducer 4, and when the diameter of the groove of the driving turntable 5 is equal to that of the groove outside the box body of the speed reducer 4, the groove can be directly formed in the box body of the speed reducer 4.
When the field oil pumping equipment works, the motor 1 alternately rotates in the forward direction and the reverse direction, power is transmitted to the speed reducer 2 through the coupler 2, and the speed reducer 2 is driven to rotate by the box body after speed reduction, so that the driving turntable 5 arranged on the box body is driven to rotate; since the drive turntable 5 is mounted on the casing of the reduction gear 4, the casing of the reduction gear 4 and the drive turntable 5 operate synchronously. The flexible polished rod 9 is wound on a wheel groove of the driving turntable 5, the balancing flexible rope 11 is wound on a groove on the outer side of the box body of the speed reducer 4, and the other end of the balancing flexible rope is connected with the balancing box 13 by bypassing the fixed pulley 12; thus, when the driving turntable 5 and the speed reducer 4 synchronously rotate in the positive and negative directions, the underground rod column and the balance box 13 are driven to move up and down through the flexible polished rod 9 and the balance flexible rope 11, and the pumping action is realized. When the diameter of the groove of the driving turntable 5 and the diameter of the outer groove of the box body of the speed reducer 4 adopt two different diameters, the stroke of the balance box 13 is smaller than that of the rod column, the height of the support 8 can be reduced, and the range is extended.
