Abstract
The utility model discloses a device for vertically adjusting the balance of a crank of a beam-pumping unit, which relates to the balancing technology of beam-pumping units and solves the problems existed in other technologies. The structural relation of the device is as follows: a balance weight is fixed on the crank and provided with a balance weight lifting hole; the crank is fixed on an output shaft through a crank set screw; a reduction box is fixed on a reduction box output shaft; a motor is connected with the reduction box through a transmission band; a support arm is fixed at the tail end above the crank; a wire rope sleeve is positioned in the channel steel of the support arm and penetrated into the crank gap of the reduction box output shaft; a chain block is hung on the wire rope sleeve; and another wire rope sleeve is penetrated into the balance weight lifting hole to be connected with the lifting hook of the chain block. The device has the advantages of simple structure, convenient operation, easy carrying and high adjusting efficiency.
Description
One, technical field: the utility model relates to a kind of balance of well pumping unit technology, especially vertically adjusts the beam type oil pumping machine crank bascule
Two, background technology: the employed oil pumper major part in each oil recovery factory, oil field is the above big machines of 12 types at present, and the oil pumper both sides do not have fitting operation platform and guardrail.The method of operating of traditional adjustment oil pumping machine crank balance is that crank is parked near horizontal level, personnel stand in and adjust operation on the reduction box, stand in above the crank when having some employees to operate, violated the safety operation regulation, the residing height of operating personnel more than 2 meters, belongs to work high above the ground some side, and this work can't be fastened the safety belt again, inconsistent with safety requirements, and waste time and energy.In these years, many security incidents in the balancing operating process, occur, and afterwards for the sake of security, when balancing, utilized crane to cooperate, and oil pumping machine crank was parked in vertical position operates, increased the crane cost of use.
Three, summary of the invention: the purpose of this utility model provides a kind of easy and simple to handle, safe and reliable vertical adjustment beam type oil pumping machine crank bascule, it has solved the problem that other technology exists, the purpose of this utility model is to realize like this, it is to be formed by connecting by balance weight, crank, balance weight lifting hole(eyelet), reduction box, jack, steel wire loop, support arm, support arm fixed screw, crank fixed screw, reduction gearbox output shaft and motor, balance weight is fixed on the crank, and the balance weight lifting hole(eyelet) is arranged on the balance weight; Crank is fixed on the output shaft by the crank fixed screw, and reduction box is fixed on the reduction gearbox output shaft; Motor is connected with reduction box by transport tape; Support arm is fixed on the crank upper extremity, and steel wire loop is positioned at the channel-section steel of support arm, and penetrates in the crank gap of reduction gearbox output shaft end; Jack hangs on the steel wire loop, penetrates in the balance weight lifting hole(eyelet) with another root steel wire loop to be connected with the jack suspension hook.
During work, unload loose balance weight fixed screw, adjust jack, on put forward or transfer the purpose that balance weight can be realized balancing.
The meaning of this device: the one, simple in structure, easy to operate, be easy to carrying, adjust the efficient height.The 2nd, need not unload anti-skidding lock dog during operation, only need unload loose balance weight fixed screw, making balance weight leave crank can adjust.The 3rd, utilize this device to carry out the balancing operation, time saving and energy saving, safe and reliable, eliminated the risk of work high above the ground, also avoided balance weight to drop, the hidden danger of the accident that causes casualties.The 4th, saved cost of use.The 5th, shorten the operating time, rate and crude output when having improved the driving a well of oil well.
Four, description of drawings: Fig. 1 is the vertical structural representation of adjusting the beam type oil pumping machine crank bascule, among the figure 1, balance weight 2, crank 3, balance weight lifting hole(eyelet) 4, reduction box 5, jack 6, steel wire loop 7, support arm 8, support arm fixed screw 9, crank fixed screw 10, reduction gearbox output shaft 11, motor
Five, the specific embodiment: in Fig. 1, balance weight 1 is fixed on the crank 2, and balance weight lifting hole(eyelet) 3 is arranged on the balance weight 1; Crank 2 is fixed on the output shaft by crank fixed screw 9, and reduction box 4 is fixed on the reduction gearbox output shaft 10; Motor 11 is connected with reduction box 4 by transport tape; Support arm 7 is fixed on crank 2 upper extremity by support arm fixed screw 8, and steel wire loop 6 is positioned at the channel-section steel of support arm 7, and penetrates in crank 2 gaps of reduction gearbox output shaft 10 ends; Jack 5 hangs on the steel wire loop 6, penetrates in the balance weight lifting hole(eyelet) 3 with another root steel wire loop to be connected with jack 5 suspension hooks.
