Description

Low dwarf forms all balance long stroke oil pump
Technical field: the utility model belongs to oil recovery machiner equipment technical field in the oil development, is a kind of low dwarf forms all balance long stroke energy-conserving oil pumping equipment that is used for ground, oil field pumping crude oil.
Background technique: kind surplus the domestic production long-stroke pumping unit without walking beam has ten at present, these pumping unit common features are: drive power and be installed on the top platform of pylon, the forward and reverse rotation of head sheave above power driving part is driving, twining the flexible dynamic transmission part on the head sheave, flexible dynamic transmission part one end is connected with the well head sucker rod, and the other end connects balancer weight.Though these pumping units have improved equilibrium condition, realized long stroke, but their shortcoming is the top that power driving part all is in pylon, in order to realize long stroke, the pylon height is much larger than the stroke of sucker rod, make complete machine very huge, not only increased equipment investment, and installation and regular maintenance are extremely inconvenient.
Summary of the invention: the purpose of this utility model provides a kind of equilibrium condition that can effectively improve pumping unit, reduces the oil extraction cost, improves the low dwarf forms all balance long stroke oil pump of system efficiency of pumping well.
The utility model is by motor, braking device, speed reducer, coupling, drive main spindle, frame, regulate leading screw, guide rail and balance crane box part are formed, wherein motor connects with speed reducer, connect braking device between motor and the speed reducer, speed reducer links to each other with drive main spindle by coupling, frame is installed on the guide rail, regulating leading screw one end is connected with guide rail, the other end is connected with frame, it is also by the motivational drive rotating disk, bearings, static pulley, the balance steel cable, flexible polished rod, support and box drive disk part and form, wherein drive main spindle is installed on the bearings, box drives rotating disk and is installed on the motivational drive rotating disk, the motivational drive rotating disk is fixed on the drive main spindle, bearings is fixed on the frame, one end of flexible polished rod is connected with down-hole roofbolt parts, the other end is walked around the race of motivational drive rotating disk and is fixed on the perforate position of race, one end of balance steel cable twines and is fixed on the race perforate position that box drives rotating disk, and the other end is walked around rack-mount static pulley and is connected with the balance box.
Motivational drive rotating disk and box drive the cone pulley structure that rotating disk can also be integral type processing; Motivational drive rotating disk and box drive rotating disk can also adopt same diameter.
Compared with the prior art the utility model has following advantage: power-transmitting part places on the basis, ground, makes things convenient for I﹠M; When reducing support height, realize long stroke, and make complete machine shorter and smaller.
Description of drawings: accompanying drawing 1 is a structure diagram of the present utility model;
Accompanying drawing 2 is left views of Fig. 1;
Accompanying drawing 3 is partial schematic diagrams that motivational drive rotating disk 6 and box drive rotating disk 16.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing: the utility model is by motor 1, braking device 2, speed reducer 3, coupling 4, drive main spindle 5, frame 8, regulate leading screw 9, guide rail 10 and balance box 14 parts are formed, wherein motor 1 connects with speed reducer 3, connect braking device 2 between motor 1 and the speed reducer 3, speed reducer 3 links to each other with drive main spindle 5 by coupling 4, frame 8 is installed on the guide rail 10, regulating leading screw 9 one ends is connected with guide rail 10, the other end is connected with frame 8, it is also by motivational drive rotating disk 6, bearings 7, static pulley 11, balance steel cable 12, flexible polished rod 13, support 15 and box drive rotating disk 16 parts and form, wherein drive main spindle 5 is installed on the bearings 7, box drives rotating disk 16 and is installed on the motivational drive rotating disk 6, motivational drive rotating disk 6 is fixed on the drive main spindle 5, bearings 7 is fixed on the frame 8, one end of flexible polished rod 13 is connected with down-hole roofbolt parts, the other end is walked around the race of motivational drive rotating disk 6 and is fixed on the perforate position of race, one end of balance steel cable 12 twines and is fixed on the race perforate position that box drives rotating disk 16, and the other end is walked around the static pulley 11 that is installed on the support 15 and is connected with balance box 14.
Motivational drive rotating disk 6 and box drive the cone pulley structure that rotating disk 16 can also be integral type processing; Motivational drive rotating disk 6 and box drive rotating disk 16 can also adopt same diameter, makes well head roofbolt stroke identical with balance box 14 strokes.
During pumping unit work, motor 1 clockwise and anticlockwise running becomes the slow-speed of revolution with high rotating speed by speed reducer 3, gives main shaft 5 by coupling 4 with transmission of power, drives superincumbent motivational drive rotating disk 6 rotations are installed; Because box drives rotating disk 16 and is installed on the motivational drive rotating disk 6, therefore, two rotating disk run-in synchronisms.Flexible polished rod 13 is wrapped on the race of motivational drive rotating disk 6, and balance steel cable 12 is wrapped in box and drives on the race of rotating disk 16, and the other end is walked around static pulley 11 and is connected with balance box 14; Like this when motivational drive rotating disk 6 and box drive rotating disk 16 positive and negative direction and rotate synchronously,, realize that pumping moves just by flexible polished rod 13 with balance steel cable 12 has driven the down-hole roofbolt and balance box 14 moves up and down.Because motivational drive rotating disk 6 drives rotating disk 16 with box and adopts two kinds of different diameters, the stroke that makes balance box 14 has reduced support 15 height less than the roofbolt stroke, has realized long stroke simultaneously.
