Abstract
The utility model discloses a belt tightness adjuster for a motor of an oil pumping unit. The belt tightness adjuster comprises a motor, a motor rail, an oil pumping unit base, a transmission screw and a supporting device, wherein the motor is arranged on the motor rail; the motor rail is arranged on the oil pumping unit base; the supporting device is arranged on the oil pumping unit base; an internal screw thread is formed on the supporting device and screwed with an external screw thread of the transmission screw; the front end of the transmission screw is pressed against the motor; the external screw thread on the transmission screw and the internal screw thread on the supporting device are rectangular; and when the belt tightness is adjusted, the motor of the oil pumping unit can be moved to a required position only by rotating the transmission screw, so that the belt tightness is proper and meets a requirement of four points on a line. According to the utility model, the time is shortened, the labor is saved, and the belt tightness adjuster is convenient and quick; the belt tightness adjuster is not required to be hit by a large hammer and is not required to jacked by a pry bar, so that the oil pumping unit body cannot be damaged; the labor intensity of an operator is low, and the automation degree is high; and the belt tightness adjuster has outstanding economic and social benefits.
Description
Technical field:
The utility model belongs to the motor erection unit on the oil-field oil pumper, is a kind of pumping-unit motor belt tensioner.
Background technology:
In the oil pumping of oil field; By oil pumper drive sucker rod, oil well pump oil is evacuated to ground in well; The essential motor of installing on the oil pumper is earlier motor to be put in the appropriate location when motor is installed, and driving belt is installed on motor and the belt of oil pumping machine wheel again; Adjust motor then and make the driving belt tensioning, by the bolt group motor base is fixed on the motor track at last.After oil pumper work a period of time, belt is loose, does not reach the requirement of four one lines, needs the adjustment motor position, makes its belt reach the suitable elasticity and the requirement of four one lines.The method of adjustment motor position is to prize motor with crowbar after unclamping hold-down nut at present, or knocks motor with the sledgehammer transfer, makes the position that motor moves to be needed.This method falls behind, and labour intensity is big, and efficient is low, and the off-time is long, and the operator is dangerous.
Summary of the invention:
The purpose of the utility model provides a kind of pumping-unit motor belt tensioner, and the adjustment motor saves time, laborsaving, and convenient, fast.
The purpose of the utility model is achieved in that and comprises motor, motor track, oil pumping unit base, drive screw, bracing or strutting arrangement; Motor is installed on the motor track; The motor track is installed on the oil pumping unit base, and bracing or strutting arrangement is installed on the oil pumping unit base, and internal thread is arranged on the bracing or strutting arrangement; The internal thread on the bracing or strutting arrangement and the external screw thread of drive screw screw, and the front end of drive screw withstands motor.
External screw thread on the drive screw, the internal thread on the bracing or strutting arrangement are rectangular thread.
The beneficial effect of the utility model is: when regulating the belt degree of tightness, only need the rotation drive screw just can pumping-unit motor be moved to needed position, make the degree of tightness of its belt suitable; Reach the requirement of four one lines, because the rotation drive screw can produce very big push-pull effort, therefore; The utility model saves time, laborsaving, and convenient, fast, need not break with sledgehammer; Need not push up with crowbar, can not damage oil pumper portion body, operator's labour intensity is low; Automaticity is high, has remarkable economic efficiency and social benefit.
Description of drawings:
Fig. 1 is the installation diagram of the utility model embodiment.
Embodiment:
Below in conjunction with accompanying drawing the utility model embodiment is described.
Can know by Fig. 1; The embodiment of the utility model comprises motor 1, motor track 2, oil pumping unit base 3, drive screw 4, bracing or strutting arrangement 5, and motor 1 is installed on the motor track 2, and motor track 2 is installed on the oil pumping unit base 3; Bracing or strutting arrangement 5 is installed on the oil pumping unit base 3; On the bracing or strutting arrangement 5 internal thread is arranged, the external screw thread of internal thread on the bracing or strutting arrangement 5 and drive screw 4 screws, and the front end of drive screw 4 withstands motor 1.Internal thread on external screw thread on the drive screw 2, the bracing or strutting arrangement 5 is a rectangular thread.
Bracing or strutting arrangement 5 is fixed into one with oil pumping unit base 3, during use, rotates drive screw 4; Motionless because of bracing or strutting arrangement 5, drive screw 2 will be walked, under threaded function; Turning moment produces thrust; Make displacement motor, it is adjusted to the position that needs, thereby realize that the belt degree of tightness is regulated and the accent of four one lines.
