Description
Technical field
The present invention relates to a kind of device of regulating the drivign belt degree of tightness, especially a kind of convenient device of regulating pumping-unit motor drivign belt degree of tightness.
Background technique
At present, the oil production in China's oil industry every year is reducing gradually, and the demand of oil is but day by day strengthened, and this just requires the petroleum industry produced quantity of will trying every possible means to strengthen, and comes the assurance demand.Rate when wanting to strengthen produced quantity and will aspect mechanical oil recovery, improve well, guarantee stable production of crude oil, pumping unit is out of order less or the back maintenance of being out of order to stop the well time short more good more, the fault that pumping unit has easily is the lax and fracture of drivign belt, and this failure ratio is more frequent, relatively wastes time and energy when changing and regulate the belt degree of tightness, must be with motor ditch, jackscrew top, prize motor with crowbar, impact the way in motor ditch, reach mobile motor with sledgehammer.This old-fashioned method is very inconvenient, and promptly time-consuming effort was again once stopped the well time more than 30 minutes.In particular cases stopping the well time can be longer, as: under the situation of overexerting during mobile motor with its damage, and the belt of adjusting in this way or changing does not also reach quality requirement, go up inclined to one side belt easily, easily cause belt wearing and tearing aggravation during operation, new belt fault takes place, also waste belt, rate when these all directly reduce well has reduced produced quantity.
Summary of the invention
The object of the invention is to provide a kind of belt tension device of pumping unit, can solve the pumping unit drivign belt and adjust and change inconvenient problem.
The technical solution adopted for the present invention to solve the technical problems is: belt tension device of pumping unit includes base plate, slide plate, leading screw, feed screw nut, crotch and limited cover, crotch is fixedlyed connected with base plate, feed screw nut is fixedlyed connected with slide plate, slide plate is assemblied between the preceding slideway and rear slide of base plate, the axle of leading screw is assemblied in the axis hole of crotch, limited cover is in the left side of crotch and threads of lead screw assembling, and the shaft shoulder of leading screw is on the right side of crotch, the long filament of leading screw and feed screw nut screw fit.
The invention has the beneficial effects as follows, belt tension device of pumping unit is under the situation of not dismantling the motor stone bolt, just can drive slide plate by rotating threaded shaft and move forward and backward, change the wheelbase between motor pulley and the belt follower in base plate upper edge slideway direction, thus lax or swelling belt.So just can accomplish that tight belt need not stop well, change conveniently purpose of belt, change belt and stop the well time and be no more than two minutes at most, rate when improving well greatly increases the produced quantity of crude oil, and saves the man power and material.
