Reducing wheel group, elevator wheel, big belt wheel, motor and Combined balance weight block；The left and right two ends of the top platform of described pylon are cut with scissors respectively
It is connected to the first leading arm and the second leading arm, the outside of the first leading arm and the second leading arm is separately installed with the first guide wheel and
Two guide wheels, described first reducing wheel group and the second reducing wheel group are separately fixed at the first leading arm and the inner side of the second leading arm,
Described elevator wheel and big belt wheel rotate coaxially setting, and are fixed on the central authorities of tower top platform, and described motor is fixed on greatly
Between belt wheel and the second reducing wheel group, and motor is connected by belt with big belt wheel, and the bull wheel of described elevator wheel passes through first
Deceleration pull rope is connected with the bull wheel of the first reducing wheel group, and the steamboat of described elevator wheel passes through the second deceleration pull rope and second
The bull wheel of reducing wheel group is connected, and the steamboat of the first reducing wheel group is connected with one end of the first pull rope, the first pull rope another
One end is bypassed the first guide wheel and is connected with the first polished rod eye, and the steamboat of the second reducing wheel group is connected with one end of the second pull rope,
The other end of the second pull rope is bypassed the second guide wheel and is connected with the second polished rod eye, and the top platform of described pylon is further fixed on
Control chamber, the lower end central authorities of the top platform of described pylon are further fixed on the first counterweight directive wheel and the second counterweight directive wheel, institute
State the bottom that Combined balance weight block is located at pylon central authorities.
Preferably：The upper end of the top platform of described pylon is additionally provided with protective cover.The protective cover one being adopted
Formula designs, and had both protected upper mounting plate part to prevent sunlight direct irradiation, and can prevent rainwater again.
Preferably：The width of described pylon two end portions is the half of the width of pylon mid portion.Due to two
While being provided with leading arm, load can be preferably born in the reduction of pylon width, and intermediate width increases and internally can place configuration, and this
Structural soundness is good, can bear the oil pumping draw-bar pull compared with big load and Cross Wind Force load.
The present invention having the beneficial effects that compared with prior art：1st, due to using special reducing wheel group, not slowing down
Case etc., therefore whole machine transmission efficiency is compared existing product and is improved more than 5%, really realizes high performance-price ratio；
2nd, 180 ° of whole equipment need not be rotated, only standby balancing weight Fast Installation need to be can achieve that any individual well continues
Operation；
3rd, in addition leading arm vernier device and well head can be passed through according to the arbitrarily devised tower length of twin-well actual range
Distance；
4th, balancing weight is combination type, be respectively suitable for twin-well load differ greatly, the operating mode such as individual well operation, carry out the essence of pulling force
Really balance is it is ensured that motor operation is in optimum state, simultaneously also energy-conservation to a greater extent；
5th, due to not having gearbox structure to compare existing twin-well oil-pumping machine cost savings more than 25%, because the present invention is automatically controlled
And the double-well sharing such as steel construction is a set of, therefore compares 2 equipment assembly instincts of individual well oil pumper and save more than 50%.
