[0033] In this embodiment: By providing the mounting shaft 18, it is convenient to install the mounting seat 1 on the oil extraction equipment bracket and the like.

[0034] Working principle: When it is necessary to install the counterweight, the staff uses the cooperation of the peripheral hoisting equipment and the second lifting block 17 to hoist the mounting seat 1 above the oil extraction equipment bracket. At the same time, through the cooperation of the mounting shaft 18 at the bottom of the mounting seat 1 and the peripheral shaft pin, the mounting seat 1 is installed with equipment such as the bracket and the connecting rod;

[0035] Next, the staff uses the peripheral hoisting equipment in cooperation with the first hoisting block 16 to hoist the walking beam 2 and the pony head 3 above the mounting seat 1. At the same time, the positioning boxes 5 on both sides of the bottom of the walking beam 2 are inserted into the inner cavity of the positioning ports 4, so as to realize the positioning of the walking beam 2 and the mounting seat 1. Then, the staff drives the rotation of the rotating shaft 9 by using the peripheral electric wrench and the driving nut 12 in cooperation. The rotating shaft 9 drives the main bevel gear 10 to rotate, the main bevel gear 10 drives the driven bevel gear 11 to rotate, and the driven bevel gear 11 drives the screw rod 7 to rotate threadedly on the inner surface of the pin block 8, so that the pin block 8 moves and inserts into the inner cavity of the pin slot 6. At the same time, the pin block 8 drives the stud 13 to move. When the connection between the pin block 8 and the pin slot 6 is closely fitted, the staff rotates the movable limit nut 14 in turn, so that the limit nut 14 rotates and moves threadedly on the outer surface of the stud 13, so that the limit nut 14 drives the gasket 15 to move and closely fit with the connection of the positioning box 5, realizing the limit of the pin block 8 and completing the installation of the walking beam 2 and the mounting seat 1;

[0036] When the balance weight needs to be disassembled, the staff performs the above operations in reverse, and the disassembly of the balance weight can be realized.
