Description
Technical field
The utility model relates to the oil exploitation oil pumper, and particularly a kind of chain type oil pump chain transmission system is used for chain type oil pump, realizes the transmission of power and the counterweight balance of chain type oil pump.
Background technology
The chain type oil pump chain transmission system is the important component part of chain type oil pump, is undertaking transmission of power, counterweight balance and the lubricated task of chain type oil pump.Chain transmission system commonly used at present roughly has following several: two patents of CN86102978A and ZL200620085856.4 disclose two kinds of chain type oil pumps respectively, the commutation programme of CN86102978A patent is, the slide block that horizontal installation can move horizontally on vertically moving round frame, be connected with commutation chain link upper pin by bearing, the relative slide block of bearing pin can rotation, stirred when centre of sprocket is rotated by sprocket wheel when the commutation chain link, bearing pin drives slide block and laterally moves, and realizes commutation.Because the application life of slide block structure is short, the ZL200620085856.4 patent is transformed into coaster with slide block, has improved application life.The CN86102978A patent adopts the gas bascule aspect counterweight balance, poor reliability, the ZL200620085856.4 patent is transformed into the pouring weight balance with the gas bascule, and reliability is improved, but this kind drive system structure complexity, efficient is low, manufacturing cost is high, insufficient lubrication fault rate height.
Summary of the invention
The purpose of this utility model provides a kind of chain type oil pump chain transmission system, overcome the above-mentioned defective that existing chain type oil pump chain bascule and reversing arrangement exist, make the safe and reliable of chain transmission system, reduce the manufacturing cost of chain drive pumping unit.
The present technique solution can reach above-mentioned purpose: a kind of chain type oil pump chain transmission system comprises reversing arrangement and bascule, and bascule is provided with tandem-driving bogie, and reversing arrangement is provided with commutation chain link and commutation connecting rod, bearing support is fixed on the top of tandem-driving bogie.The upper end connecting axle bearing of commutation connecting rod, its lower end connect the commutation chain link.Couple together by commutation connecting rod and bearing support bascule and reversing arrangement, realize transmission of power and counterweight balance chain drive pumping unit.
The utlity model has following useful effect: this chain transmission system couples together bascule and reversing arrangement by commutation connecting rod and bearing support, and its simple in structure, reliable operation has reduced the manufacturing cost of chain type oil pump.On chain, set up and carry oil box, make the lubricating condition of chain obtain effective improvement, improved the application life of chain, reduced the maintenance cost of chain drive pumping unit.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing, a kind of chain type oil pump chain transmission system comprises reversing arrangement and bascule.Bascule comprises tandem-driving bogie 1, roller 3 and belt 2, one end stable equilibrium case 1 of belt 2, walking around roller 3 links to each other with wellhead polish rod, the weight of tandem-driving bogie 1 and well head payload segment are offset the effect that reduces driving force that reaches, tandem-driving bogie 1 inner equilibrium piece is adjustable, so that accurate balance well head load, tandem-driving bogie is installed guiding wheels 12 for 1 four jiaos.Reversing arrangement is provided with commutation connecting rod 6 and commutation chain link 8, and commutation chain link 8 is connected with chain 9.Bearing support 5 is fixed on the top of tandem-driving bogie 1, and commutation connecting rod 6 upper ends are connected with bearing support 5, and the lower end is connected with the chain link 8 that commutates.Bearing support 5 is fixed on the top of tandem-driving bogie 1 and the position of chain 9 one side central lines, and block 7 is equipped with in tandem-driving bogie 1 bottom of the opposite side relative with bearing support 5 permanent positions.When commutation chain link 8 moves to opposite side chain 9 position of center line relative with bearing support 5, block 7 inboard with commutation connecting rod 6 lower ends in side contacts.The rotation direction of chain 9 is defined as the chain that is positioned at bearing support 5 one sides and moves downward.When commutation chain link 8 was on the chain center line of the same side with bearing support 5, chain 9 and commutation connecting rod 6 were subjected to force direction on same straight line, and stressed size equals the poor of polished rod load and equilibrant force.Chain 9 drives tandem-driving bogie 1 and moves downward, and tandem-driving bogie 1 drives the oil well polished rod and up moves.When commutation chain link 8 moved to lower sprocket 10 central horizontal positions, commutation connecting rod 6 connect the opposite side position that circle turns to lower sprocket 10 centers with commutation chain link 8 along sprocket wheel, realizes commutation.This moment, tandem-driving bogie 1 up moved, and drove the oil well polished rod and moved down.The lower end of commutation connecting rod 6 moves to the central lines of the opposite side and the opposite side chain of chain 9 with commutation chain link 8.In the moving process commutation connecting rod 6 lower ends inboard with block 7 in side contacts, the connecting rod 6 side stay chains 9 that prevent to commutate cause chain 9 stressed deteriorations, make that chain 9 is stressed still to equal the poor of polished rod load and equilibrant force, have improved the stress condition of chain 9.When commutation chain link 8 moved to upper sprocket wheel 4 central horizontal positions, tandem-driving bogie 1 quilt commutation connecting rod 6 was shifted the upper position of upper sprocket wheel 4 onto, and commutation connecting rod 6 moves to the opposite side position at upper sprocket wheel 4 centers along pitch circle position, upper sprocket wheel 4 top with commutation chain link 8.Tandem-driving bogie 1 begins descending again, drives the oil well polished rod and moves down, and sucker rod is realized once moving back and forth, and oil pumper has been finished a stroke procedure.Fixedly carry oil box 11 on chain 9, the box body of carrying oil box 11 is provided with oil-in, when carrying oil box 11 and move to the below of lower sprocket 10, the lubrication oil in the lower sprocket 10 below oil sumps can be poured into wherein, forms the lubrication mode of Waterwheel-type.Along with moving of chain 9, to carry oil box 11 and the oil of bottom oil sump can be mentioned top, the bearing of lubricated upper sprocket wheel 4 and other bearings guarantee lubricant effect.
