Detailed description of the invention
As shown in Fig. 1 ~ 2, the utility model provides a kind of belt of oil pumping machine and adjusts more changing device, comprise bottom girder 1 and motor base 2, turning end and the described bottom girder 1 of described motor base 2 are hinged, motor base 2 is connected on bottom girder 1 by axle and axle sleeve, when motor base 2 sways, the relative bottom girder 1 of height of the other end (namely lift side) changes.Motor can be fixed on motor base 2 and (motor base of Fig. 1 be fixed with motor, not shown motor in Fig. 2).The lift side of described motor base 2 is fixedly connected with elevating mechanism 3, and described elevating mechanism 3 and described bottom girder 1 are rotationally connected.
As shown in Figure 3, described elevating mechanism 3 comprises feed screw nut 31 and leading screw screw rod 32, and described bottom girder 1 is also provided with screw foot 11, and described leading screw screw rod 32 is rotationally connected by spherical pair with described screw foot 11.The lateral wall of described feed screw nut 31 is fixed with linking arm 33, and described feed screw nut 31 is connected with described motor base 2 by described linking arm 33.Described motor base 2 is also provided with linking arm cover 21, described linking arm 33 is arranged in described linking arm cover 21.The top of described elevating mechanism 3 is provided with handwheel, and namely the top of screw mandrel screw rod 32 connects handwheel (not shown).
By regulating elevating mechanism 3, and then regulate motor base 2, the motor height on motor base 2 is changed thereupon: when changing belt, regulate elevating mechanism 3 that motor base 2 is raised, cause belt to be relaxed, then take off belt and change; When sleet sky belt creep, regulate elevating mechanism 3 that motor base 2 is reduced, tighten belt to increase frictional force.When rotating threaded shaft screw rod 32, feed screw nut 31, by linking arm 33 drive motor base 2, realizes the lifting of motor base 2, simple to operate, improves operating efficiency, reduces the field accident because too much manual operation may cause.On the pumpingh well of " sand is large " or " wax is large " during operation, the adjustment replacing construction of belt is long, the impurity in crude oil (sand) can be made to be deposited in oil well pump and easily to occur holddown phenomenon, cause " secondary operation ", bring unnecessary loss to the production in oil field.The utility model can shorten belt replacing regulation time greatly, avoids " secondary operation " situation.
Elevating mechanism 2 is connected with bottom girder 1, the effective length shortening screw mandrel screw rod 32, thus reduces the probability of screw mandrel screw rod 32 bending in use procedure.
Leading screw screw rod 32 and described screw foot 11 adopt spherical pair to be rotationally connected, and namely leading screw screw rod 32 bottom is bulb, and screw foot is bulb base.Elevating mechanism 3 is in lifting process, and inclination to a certain degree can occur lifting screw 32, and that is it is not in vertical state, by the cooperation of bulb and bulb base, the angle of lifting screw 32 can within the specific limits from Row sum-equal matrix, without the need to human intervention, this improves operating efficiency.In addition, it is not fixing that linking arm 33 and linking arm overlaps 21, and therefore, one set of lifting mechanism 3 can Reusability, and can according to the size of motor base 2, and adjustment linking arm 33 penetrates linking arm and overlaps length in 21, thus is suitable for the motor base 2 of different size.
