The traction bracket 300 is connected to the first lifting bracket 510, and the propulsion bracket 400 is connected to the second lifting bracket 520. The traction bracket 300 and the propulsion bracket 400 drive the lifting mechanism to slide along the direction of the crank 200. The lifting mechanisms on both sides fix the balance block 100 and drive the balance block 100 to rise and fall.
[0031] When the position of the balancing block 100 needs to be adjusted, the lifting mechanisms on both sides clamp the balancing block 100 and lift it up and away from the crank 200. At this time, the connection between the traction bracket 300 and the propulsion bracket 400 and the lifting mechanism is adjusted, and the lifting mechanism is driven to drag the balancing block 100 along the direction of the crank 200 structure and place it in the appropriate position. After the lifting mechanisms on both sides drop the balancing block 100 to the appropriate position, the connection between the lifting mechanism and the balancing block 100 is released.
[0032] By means of the lifting mechanism arranged in front and behind the balancing block 100, the balancing block 100 and the crank 200 can be separated into a gap by lifting, which not only eliminates the adhesion between the balancing block 100 and the crank 200 that may be caused by rust, but also reduces the movement resistance of the balancing block 100 during the movement process; by means of the traction bracket 300 and the propulsion bracket 400, the pushing and pulling force can be increased, making it more convenient to move the balancing block 100 to the appropriate position.
[0033] In this embodiment, the first lifting bracket 510 and the second lifting bracket 520 are both provided with lifting claws 530 at one end close to the balancing weight 100 . The lifting claws 530 can move along the lifting direction of the balancing weight 100 .
