Description
Technical Field
The invention relates to an adjusting device of a motor of a pumping unit in the petroleum industry, in particular to an automatic adjusting device of the tightness of a motor belt of the pumping unit, which can automatically move and adjust the tightness between the motor and the belt of various pumping units and can also be used for automatically moving and adjusting various large motor belts in other use places.
Background
The pumping unit belt is a transmission device for connecting the motor and the reduction gearbox. When the pumping unit works, the belt is tired due to the up-and-down reciprocating motion and the load balance change, so the belt becomes a consumable product and needs to be replaced frequently. This brings much effort to the daily maintenance of the oil extractor. The service life of each component of the pumping unit and the operation time rate of the pumping unit are directly influenced by the replacement work of the motor belt of the pumping unit. The motor belt is not beneficial to safe production when the motor belt is stopped and replaced, so that the oil well yield is seriously influenced, and economic loss is caused.
At present, the belt of the pumping unit needs to be replaced after being stopped, a motor is detached from a sliding rail jackscrew and a sliding rail fixing bolt of the motor, the motor is moved forwards by a crow bar, the belt can be taken out from a wheel groove after being loosened, a new belt is replaced, the motor is moved backwards and fixed by the crow bar, and meanwhile, the belt pulley needs to be adjusted to keep four-point one-line, so that the operation generally needs to be carried out by two persons. At present, the well group management personnel are few, and the well group management personnel are often operated by a single person, so that the whole operation process becomes extremely difficult due to the dead weight of the motor. Too loose or too tight of the belt can affect the utilization of the motor power of the pumping unit, even the balance rate of the pumping unit, and the loss of the belt is increased. Particularly, the temperature is low in winter, the tension of the belt in a low-temperature environment is extremely poor, the damage to the belt caused by the operation is extremely serious, and the service life of the belt is greatly shortened. Readjustment is required to keep the pulley "four-point-one" whenever the motor is moved. If the four-point line is not adjusted, the belt does not work in one plane, and the service life of the belt is shortened. After the belt is loosened, the belt is seriously worn due to untimely adjustment, and the service life of the belt is influenced. At present, no device for monitoring the belt running in real time exists on site, and the belt loosening is found to be manually adjusted, so that the requirement of oil field four-purpose construction is not met.

The technical scheme of the invention is as follows: the automatic tightness adjusting device for the motor belt of the oil pumping unit comprises a support, a guide rail sliding sleeve, a motor fixing seat and an adjusting screw rod, wherein the guide rail is sleeved outside the guide rail in a sliding manner, the support is fixed at two ends of the guide rail, the motor fixing seat is fixed on the guide rail sliding sleeve, and a nut is fixed on the lower end face of the motor fixing seat and is in threaded connection with an external thread of the adjusting screw rod arranged in the support. The adjusting motor and the infrared proximity switch are connected with the data transmission control cabinet through cables, and an output shaft of the adjusting motor is meshed with the adjusting screw; the cable of the data transmission control cabinet is connected with the ground electric control cabinet, and the data cable or the wireless transmission equipment is connected with the regional network center.
Compared with the prior art, the invention has the remarkable use effects that: the support in the device is fixed on the base of the pumping unit, the adjusting motor rotates to drive the adjusting screw rod to rotate so as to enable the motor fixing seat to move backwards or forwards, and the motor is fixed on the motor fixing seat and moves backwards or forwards along with the motor. An infrared proximity switch is arranged on the guide rail sliding sleeve, when the motor belt is loosened in the running process, the belt contacts the radiation range of the infrared proximity switch, and the infrared proximity switch transmits a command to the data transmission control cabinet, so that the adjusting motor rotates, and the purposes of automatically adjusting and tensioning the motor belt are achieved. The device has the function of monitoring the running condition of the belt in real time, and monitoring data is transmitted to a monitoring room in real time by relying on the regional network center of the oil field. The automatic motor belt adjusting device has the advantages of short operation time, high efficiency, automatic adjustment at any time, no need of a crow bar, no need of loosening a motor fixing bolt, automatic adjustment of a motor belt, no need of personnel operation and completion in 1 minute. The position of the motor can be adjusted left and right through the jackscrews, so that the 'four-point one-line' adjustment of the motor belt pulley can be realized rapidly and accurately. The device realizes the manual and automatic switching, can be manually adjusted under the condition that the automatic adjustment cannot be realized, and does not delay the production. The dust cover is designed outside the threads of the adjusting screw, so that the threads are effectively prevented from being rusted. The adjusting screw positioning bolt and the guide rail sliding sleeve positioning bolt are respectively provided with a yellow oil hole, and have the dual functions of adjustment and lubrication. The device not only reduces labor intensity, but also saves manpower, material resources and time, can safely and effectively solve the operation risk brought by replacing the motor belt, reduces the labor intensity of workers, eliminates illegal operation, and can provide accurate positioning for four points and one line of two belt pulleys. The service life of the motor belt is prolonged, effective protection is provided for the pumping unit, the well stopping time is obviously reduced, the oil well yield is improved, and the motor belt has good use effect and application value.
