[0014] When the first-level vertical beam descends to the extreme position, the buffer abuts against the top of the sleeve unit, thereby avoiding collision between the first-level vertical beam and the sleeve unit.
[0015] The beneficial effects of the utility model are as follows: the utility model is a vertical beam pulley structure with a weighing sensor, and the electric cylinder moves to drive the first-level vertical beam sleeve unit to rise and fall relative to the sleeve unit. At the same time, the movable pulley follows the first-level vertical beam to rise and fall; the total length of the sprocket remains unchanged, one end is connected to the weighing sensor, and the other end is wound around the fixed pulley and connected to the second-level vertical beam, so that the movable pulley moves upward, and the second-level vertical beam follows the upward movement under the drive of the sprocket; the weighing sensor detects the state of the second-level vertical beam in real time, realizes real-time detection of the force on the second-level vertical beam, and ensures the safety of the second-level vertical beam.
