Abstract
The utility model relates to a motor belt tightness adjustment device which comprises a base, a rack, a gear, a spanner, a lower ratchet wheel and an upper ratchet wheel. The rack penetrates through a through hole of the middle of the base, the gear is arranged above the gear, the gear matches with the rack to work, the lower ratchet wheel and the upper ratchet wheel match with the gear to work, the lower ratchet wheel is arranged in front of the rear, and the lower portion of the ratchet wheel is hinged with the base. Two ends of a spring are respectively connected with the base and the lower ratchet wheel. The rear is arranged inside a groove on the lower portion of the spanner, and the upper ratchet wheel is connected with the spanner through a torsion spring. The motor belt tightness adjustment device is simple in structure, low in cost, simple to operate, large in moving speeds of the motor, and capable of shortening time of replacing a belt of an oil well. Work efficiency is obviously improved, and oil-well-exploring efficiency is correspondingly improved, and crude oil yields of the oil well are indirectly increased.
Description
Technical field
The utility model relates to a kind of electric motor belt slack adjuster.
Background technique
Present oil field pumping unit and water injection pump used, all to use motor as power source, and be connected with the input shaft of speed reducer by belt transmission, the tightness of adjusting belt is to come the position of regulating electric machine by regulating electric machine jackscrew, tradition utilizes jackscrew to regulate following deficiency, 1, the jackscrew stroke is longer, and when directly contacting with motor, surface of contact between the side of motor and the arc surface of motor jackscrew is little, when being subjected to external force excessive, jackscrew screw rod perk bending easily occuring or damage, even causes jackscrew to scrap; 2, due to the jackscrew baffle plate inside the motor slide rail and the restriction of motor jackscrew self length, sometimes jackscrew can't immediate roof on motor, normally add a square iron block between strike base and motor jackscrew and move, its steadiness is relatively poor like this, pushes up the easy slippage ejection of getting on and hurts sb.'s feelings.
Summary of the invention
It is a kind of simple in structure, easy for installation that the purpose of this utility model is to provide, and uses safe, convenient, fast, practical electric motor belt slack adjuster.
The technical solution of the utility model is:
the electric motor belt slack adjuster, comprise base, tooth bar, gear, spanner, bottom ratchet wheel, upper ratchet, tooth bar passes the through hole at base middle part, tooth bar can move forward and backward, gear is positioned at above tooth bar, the wheel and rack cooperating, bottom ratchet wheel and upper ratchet and gear cooperating, bottom ratchet wheel is positioned at gear the place ahead, the effect of bottom ratchet wheel is to prevent the gear backward rotation, bottom ratchet wheel bottom and base are hinged, the two ends of spring connect respectively base and bottom ratchet wheel, gear is positioned at the groove of spanner bottom, upper ratchet is connected with spanner by torsion spring, upper ratchet can order about the gear forward rotation by the swing of spanner.
Described tooth bar end is hinged with push pedal.
Described base bottom arranges dovetail groove.
Working principle of the present utility model is: base is fixed on motor slideway, spanner moves forward by upper ratchet handsetting gear band carry-over bar, thereby make motor move forward tightening belt, after motor fixes, then handle is rotated forward, spanner lifts lower ratchet and upper ratchet simultaneously, and gear can backward rotation, move backward by manual promotion tooth bar, then the utility model is unloaded from motor slideway.
The beneficial effects of the utility model are: simple in structure, cost is low, and is simple to operate, motor removing speed is fast, shortened the time that oil well is changed belt, and working efficiency obviously improves, and correspondingly improved rate when driving a well, and indirectly increased the crude output of oil well.
