Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described:
As shown in Figure 1 and Figure 2, a kind of double rack tower-type pumping unit of the utility model, primarily of compositions such as base 1, frame 2, cushion cap guide rail 3, cushion cap 4, reducer 5, motor 6, reducer output shaft gear 7, driving wheel 8, driving wheel slide block 9, guide rail link 10, slide block guide rail 11, annular rack 12, balance slide block 13, balance slide block tie-beam 14, cylinder 15, wire rope 16, directive wheel 17, polished rod eyes 18.Described frame 2 is installed symmetrically two balance slide block 13; Balance slide block 13 is respectively installed with an identical annular rack 12, defines the structure of double rack, connected by balance slide block tie-beam 14 between two balance slide block 13; Frame is also installed with slide block guide rail 11 and cushion cap guide rail 3, connects with guide rail link 10 between cushion cap guide rail 3 and driving wheel slide block 9; Slide block guide rail 11 is provided with driving wheel slide block 9, driving wheel 8 can be driven to realize the commutation of oil pumper up-down stroke along slide block guide rail 11 horizontal slip; Cushion cap guide rail 3 is provided with cushion cap 4, cushion cap 4 can along cushion cap guide rail 3 horizontal slip together with motor 6 fixed thereon, reducer 5.
Described motor 6 is fixed on cushion cap 4 with reducer 5, cushion cap 4 is arranged in cushion cap guide rail 3 and also can slides along the track cross level of cushion cap guide rail 3, and cushion cap guide rail 3 is fixed in frame 2, therefore motor 6, reducer 5 and cushion cap 4 can only move horizontally in the direction of cushion cap guide rail 3; The output shaft of motor 6 is directly connected with the power shaft of reducer 5, without belt transmission; Driving wheel 8 is connected with driving wheel slide block 9, and driving wheel slide block 9 is arranged in slide block guide rail 11, and such driving wheel 8 can move horizontally along slide block guide rail 11 with driving wheel slide block 9 while rich axle rotates, to realize the commutation of oil pumper; Be connected by guide rail link 10 between driving wheel slide block 9 with cushion cap 4, to realize the synchronized movement of driving wheel 8 and motor 6, reducer 5, constant to guarantee the relative position of three; When this transmission scheme can solve in existing patent and use belt transmission, the problem that the belt pulley degree of tightness caused with the change of position between reducer due to motor changes greatly; Driving wheel 8 and annular rack 12 engage, annular rack 12 is fixed in balance slide block 13, the both sides of balance slide block 13 are provided with directive wheel 17, connected by balance slide block tie-beam 14 between two balance slide block, the both sides being arranged on frame of two balance slide block symmetries, make the stressed more balanced of frame, add the stability of oil pumper; One end of wire rope 16 is connected on balance slide block tie-beam 14, and the other end is connected with polished rod eye 18 by the cylinder 15 at frame 2 top, therefore, dynamic balance slide block 13 will be with when driving wheel 8 rotates to pump.
As shown in Figure 1, when driving wheel 8 engages with the minimum point of annular rack 12, driving wheel 8 rotates counterclockwise, annular rack 12 and balance slide block 13 is driven to move downward, simultaneously driving wheel 8 can slide into the right the low order end of annular rack 12 together along with driving wheel slide block 9 along slide block guide rail 11, now driving wheel 8 engages with the straightway of annular rack 12, and band dynamic balance slide block 13 does linear uniform motion downwards; When the top arc section of annular rack 12 and driving wheel 8 engage, driving wheel 8 level can be moved to the left while band dynamic balance slide block 13 moves downward, when balance slide block moves to lower dead center (i.e. the peak engagement of driving wheel and annular rack), driving wheel 8 moves to the mid point of slide block guide rail 11 with driving wheel slide block 9, completes down stroke motion; At lower a moment, driving wheel 8 is rotated further and slides left, and now driving wheel 8 is with carry-over bar 12 and balance slide block 13 to move upward, and completes the commutation from down stroke to upstroke; Owing to being connected by guide rail link 10 between driving wheel slide block 11 and cushion cap 4, so driving wheel slide block 9 is while driving wheel 8 moves horizontally along slide block guide rail 9 in drive, also can drive cushion cap 4 and on motor 6 level of synchronization together with reducer 5 move.This oil pumper employs new transmission scheme, improves the transmission efficiency of oil pumper; The design of double rack and balance slide block also makes the stressed more balanced of oil pumper, substantially increases the stability of oil pumper.
