Abstract
The utility model relates to a looseness-preventive regulating device of a driving belt, which is used in the belt-driving mechanism of an oil well extractor in an oil field to regulate the tightness degree of the driving belt. The utility model is characterized in that the sliding block on the upright pole of the supporting piece is formed by welding two metallic cylinders together. The sliding block takes the shape of a cross and slides on the upright pole up and down, causing a tension-regulating wheel to conduct regulations left and right. The regulator composed of a meshed gear and rack and arranged on the sliding block is connected with the tension-regulating wheel. The pressure spring on the sliding block of the upright pole conducts regulations through a regulating nut and a nut arranged on the pressure spring. The utility model can bring the driving ability of the driving belt into full play, facilitate the oil extractor to operate normally and improve the productivity by regulating the tightness degree of the driving belt. When the driving belt operates after a period of time and the original pulling power is reduced due to the looseness of the driving belt, the tightness degree of the driving belt can be regulated automatically, thereby facilitating the oil extractor to operate normally and prolonging the service life of the driving belt.
Description
Technical field the utility model relates to a kind of oilfield belt of oil pumping machine driving mechanism that is used for, and adjusts the locking regulating device of driving belt of driving belt tightness.
Background technique is present, and the traditional pumping unit of domestic oilfield is the machine of kowtowing, and is in service in oil recovery, its driving belt is after operation a period of time, and owing to driving belt follows the string or other reason, it is lax to produce driving belt, initial tension is reduced, and shortened the working life of driving belt.
The summary of the invention the purpose of this utility model is to provide a kind of locking regulating device of driving belt of adjusting the driving belt tightness for oilfield belt of oil pumping machine driving mechanism.
The locking regulating device content Description of the utility model driving belt:
The locking regulating device of the utility model driving belt, it is characterized in that: form by nut, adjustment nut, pressure spring, tension adjustment wheel, slide block, regulator, vertical rod, vertical rod is a supporting member, slide block in vertical rod is to be welded together by two metallic cylinder, be " ten " word shape, in vertical rod, can slide up and down, make about the tension adjustment wheel and adjust; Regulator on slide block is connected with the tension adjustment wheel, is made up of wheel and rack engagement, and the tension adjustment wheel is connected with the drive pulley of pumping unit again; Pressure spring above the slide block in the vertical rod is adjusted by adjustment nut and nut above it.
The locking regulating device of the utility model driving belt can be by adjusting the driving belt tightness, reach and adjust the driving belt initial tension, make it to reach reference value, and then the effective circle force that makes driving belt reaches the purpose of reference value, the transmission capacity of driving belt is not fully exerted, pumping unit is run well, boost productivity.After driving belt is moving a period of time, because driving belt relaxes when initial tension is reduced, the locking regulating device of driving belt can be regulated the driving belt tightness automatically, and the initial tension of driving belt is kept in the reasonable scope, pumping unit is normally moved, prolonged the working life of driving belt.
Description of drawings Fig. 1 is the locking regulating device structural representation of driving belt
Among Fig. 1: 1 be nut, 2 for adjust nut, 3 for pressure spring, 4 for the tension adjustment wheel, 5 for slide block, 6 for regulator, 7 be vertical rod.
The locking regulating device of embodiment the utility model driving belt is to realize like this, see Fig. 1, vertical rod 7 is supporting members of this device, be processed into by round steel, one base, the slide block 5 in vertical rod 7 are arranged at its bottom is to be welded together by two metallic cylinder, is " ten " word shape, in vertical rod 7, can slide up and down, and tension adjustment wheel about 4 is adjusted; Regulator 6 on slide block 5 is connected with tension adjustment wheel 4, is made up of wheel and rack engagement, and control slide block 5 slides up and down, and drive tension adjustment wheel 4 moves up and down; Tension adjustment wheel 4 is connected with the drive pulley of pumping unit, along in the driving belt along under the effect of regulator 6, moving up and down with slide block 5, reach the purpose of adjustment driving belt tightness; The pressure spring 3 that is installed in the vertical rod 7 is connected with slide block 5, be to adjust nut 2 and nut 1 on pressure spring 3, after turning adjustment nut 2, pressure spring 3 has certain pretightening force, pressed slider 5, and drive tension adjustment wheel 4 and compress driving belt, reach the purpose of automatic adjustment driving belt tightness.
