Description

Transmission mechanism of closed box oil pumping machine

Technical field: the present invention relates to a kind of oil field equipment.

Background technique: at present, oil field equipment of the prior art, mostly its transmission device is to adopt belt transmission, its stroke is little, and the bel-drivenn shortcoming is that power consumption is high, inefficiency, particularly crank rotates reciprocating oil pumping unit, carry out balance with balancing weight, in oil pumping process, have the shortcoming of a large amount of electric energy of waste.Transmission mechanism of closed box oil pumping machine, be the utility model patent of the inventor, on the basis of the patent No. 200820010389.8 (this utility model patent is authorized), further improve technology in application on January 23rd, 2008, carry out operation experiment over a long time simultaneously in the Liaohe Oil Field, experimental results show that; It is 37KW/h that crank rotates to-and-fro motion pumping unit employing motor.The motor that this device adopted is 7.5W/h, under the situation of equal tar productivity, this device can be saved 29.5W/h, and present technique identifies for No. 366 by distant section mirror word (2008) and the Liao Dynasty passes through through No. 087095 evaluation of skill mirror word, reaches leading domestic and advanced international standard.

Summary of the invention: the purpose of this invention is to provide a kind of power consumption that reduces, stroke is long, oil-proof and the energy-conservation transmission mechanism of closed box oil pumping machine of magnetic control, in device, with electromagnetic inductor wire rope is monitored, when wire rope is broken, pumping unit stops oil pumping, meanwhile, motor is cut off the electricity supply automatically, stops operating.

The technical solution adopted in the present invention: in transmission mechanism of closed box oil pumping machine, be with support roller, wire rope, mounting plate, supporting-roller shaft, slideway, body, driven sprocket, ballast box, circulation link chain, scroll wheel, roller shaft, case ear, circulation axis, inverting slideway, circulation wheel, drive sprocket, drive sprocket, upper support axle, shackle shaft, hanger, electromagnetic inductor, lower support axle and supporting sleeve are formed.Support roller is a circular wheel, and there is a through hole at its center.Supporting-roller shaft is the cylindrical steel body, and the centre of supporting-roller shaft is enclosed in the center hole of support roller, and support roller can rotate, and the supporting-roller shaft two ends are cemented on the support that pushes up on the body.Body is a fully enclosed stereoscopic shape housing structure, fixed shut around it, and shut is that sheet metal is made.Ballast box is the closed box of solid figure, the upper end of ballast box fixed hanger, be provided with through hole above the hanger, shackle shaft is enclosed in the through hole of hanger, wire rope one end is cemented on the shackle shaft; Wire rope is walked around the support roller top, and the other end and well bar upper end is fixed with mounting plate.The top and bottom of the intermediate portion of ballast box both sides fixed the case ear, the case ear is provided with through hole, the roller shaft string crosses that case earhole and scroll wheel hole and case ear are fixed, a through hole is established at the center of scroll wheel, scroll wheel can rotate on roller shaft.Inverting slideway be cemented in ballast box the bottom below, the substantially horizontal of inverting slideway is provided with upper and lower chute board, upper and lower chute board two ends fixed connecting plate, the upper end of connecting plate is cemented in the bottom of ballast box, the circulation wheel rolls in upper and lower chute board, the center of circulation axis is enclosed in the center hole of circulation wheel, and the circulation wheel can rotate.The scroll wheel top contacts with slideway, the slideway correspondence be arranged on two sides in the body.Monosymmetric fixed the upper support axle in middle and upper part in body, the end string of upper support axle is overlapping driven sprocket, and driven sprocket can rotate on supporting axle.Vicinity, lower end bilateral symmetry in the body fixed supporting sleeve, the lower support axle is enclosed in the center hole of supporting sleeve, the lower support axle was gone here and there the center hole of the center hole of drive sprocket and drive sprocket and was carried out fixedly, drive sprocket and driven sprocket are the bilateral symmetry device.Circulation link chain is suspended on the teeth of drive sprocket and driven sprocket and is connected, and when drive sprocket rotated, drive sprocket also rotated, and the rotation of drive sprocket makes the straight line shuttling movement of endless chain row culture vertical.So driven sprocket also rotates.Packing in the pitch circle hole of the circulation link chain termination of circulation axis, circulation axis is that substantially horizontal is enclosed in the pitch circle hole of circulation link chain; Circulation link chain is the side that is symmetricly set on two correspondences in the body.The circulation wheel rotates on circulation axis, and the circulation wheel rolls in inverting slideway simultaneously.Because the diameter of drive sprocket is greater than the diameter of driven sprocket, when circulation axis moves in the process of drive sprocket bottom commutation semi-circle, the well bar moves upward and slows down, meanwhile, the speed of oil pumping slows down, because the oil in the oil well is subjected to the spring of check valve to head on the effect of power, the compression of generation petroleum liquid, when the pumping well bar is desired to move to top dead center, the well bar moves upward and slows down, make the discharging of energy even of petroleum liquid compression, promptly petroleum liquid is arranged in the oil transport pipeline slowly, reaches the purpose that increases oil pumping yield.Upper end in body fixed electromagnetic inductor, electromagnetic inductor is monitoring the motion of wire rope, when wire rope disconnects, wire rope has broken away from the supervision and the control of electromagnetic inductor, when electromagnetic inductor is warned, the powered-down switch stops motor and rotates, and is oilfield enterprise and saves electric energy.The motor shaft of this device is connected with joiner, and joiner is connected with the driving shaft of speed reducer, the driven shaft of speed reducer fixed sprocket wheel, with chain drive sprocket and sprocket wheel are connected together.

Owing to adopt such scheme, utilize transmission mechanism of closed box oil pumping machine, it is installed in carries out operation on the oil recovery well, the advantage of comparing with other technology is: 1, energy-saving efficiency height: domestic like product electric motor power is 37KW/h, the electric motor power of this product is 7.5KW/h, can save energy 29.5KW/h.2, prolong life cycle: this device mechanical stability against short circuit is good, adopts counterweight formula balance, and the degree of balance reaches 98%.3, applied widely: this device is suitable for viscous crude, super heavy oil recovery, improves load ratio, realizes energy-efficient purpose, and this device is totally-enclosed casing, can prevent dust, and sand control, rainproof, anti-simultaneously casing produces leakage of oil.4, ballast box is provided with scroll wheel and contacts with slideway because the friction of scroll wheel and slideway is rolling friction, rolling friction and sliding friction, on year-on-year basis under, can save and consume energy more than 20%.5, carry out transmission with motor and speed reducer with shaft coupling, replace belt transmissioning mode, can save energy loss more than 25%.And, easy to maintenance.
