Fixing device for motor on pumping unit

Abstract

The invention relates to a fixing device for a motor on a pumping unit. The fixing device is structurally characterized in that two rail grooves with opposite openings are formed in a pumping unit base support, a motor base is embedded into the rail grooves, the two ends of the rail grooves are provided with rail groove sealing blocks, screw thread holes are formed in the sealing blocks, motor displacement adjusting shafts are connected into the screw thread holes through screw threads, the middles on the upper walls of the rail grooves are provided with motor fixing grooves parallel to the rail grooves, fastening bolts are arranged in the fixing grooves, the diameter of the bolt heads is larger than the width of the motor fixing grooves, the motor displacement adjusting shafts are provided with outer screw threads, and positioning holes are formed in the adjusting heads of the motor displacement adjusting shafts. The motor base is sealed into the two opposite rail grooves, the two ends of the motor base are sealed so that it can be ensured that a motor cannot be stolen, the displacement of the motor is adjusted through the screw threads of the displacement adjusting shafts, motor displacement adjustment is more convenient and accurate, the rail openings are formed in the upper walls of the rail grooves and can fix the position of the motor through the bolts, and position offset, caused by vibration, of the motor in the working process is prevented.

Description

technical field [0001] The invention relates to the technical field of oil pumping machines, in particular to a fixing device for an electric motor on an oil pumping machine. Background technique [0002] In the daily production of the oil field, the belt between the driving wheel of the motor and the auxiliary driving wheel of the balance weight is affected by the high temperature generated by friction or the high temperature of the external environment after a long period of continuous operation, and the phenomenon of belt relaxation is more likely to occur. The loose belt seriously affects the motor. The transmission effect between the driving wheel and the auxiliary driving wheel of the balance weight may even cause belt stripping, which brings certain safety hazards to the surrounding staff. Therefore, it is necessary to timely adjust the distance between the motor and the balance weight to tighten the belt, but because the motor is relatively heavy, and the motors on t...

Problems solved by technology

[0002] In the daily production of the oil field, the belt between the driving wheel of the motor and the auxiliary driving wheel of the balance weight is affected by the high temperature generated by friction or the high temperature of the external environment after a long period of continuous operation, and the phenomenon of belt relaxation is more likely to occur. The loose belt seriously affects the motor. The transmission effect between the driving wheel and the auxiliary driving wheel of the balance weight may even cause belt stripping, which brings certain safety hazards to the surrounding staff

Therefore, it is necessary to timely adjust the distance between the motor and the balance weight to tighten the belt, but because the motor is relatively heavy, and the motors on the oil field are usually directly fastened to the base bracket of the pumping unit with bolts to adjust the displacement. directly loosen the fastening bolts at the time, and rely on the staff's visual inspection to move the motor, which is time-consuming, laborious, and not accurate enough

In addition, the base of the motor is exposed outside the base bracket of the pumping unit, which is not safe enough. Illegal elements can directly remove the fastening bolts to complete theft and other damage. Theft of the motor occurs from time to time, which seriously affects the normal production of the oil field.
