Description

Traction walking board assembly and control method Technical Field The invention relates to the technical field of traction construction equipment, in particular to a traction walking board assembly and a control method. Background In the power line erection engineering, especially in the tension paying-off operation process of a high-voltage transmission line, a walking board is used as a key intermediate part between a connecting wire and traction equipment and plays important roles of wire traction, tension transmission, wire protection and the like. The walking board is usually welded by adopting a steel structure, has certain strength and rigidity, and can adapt to the traction requirements of wires of different types. However, in actual operation, the running board is often in a complex dynamic environment. On one hand, the external disturbance such as traction tension fluctuation, pulley impact, rope vibration and the like can cause periodic or transient vibration of the walking board, on the other hand, the low-frequency resonance is likely to occur in the traction process due to longer length and larger suspension of the lead, the walking board is likely to be in an unstable state such as yaw and torsional pendulum, and the like, and the structural vibration not only affects the traction construction operation efficiency, but also can cause safety risks such as lead deflection, rope sloughing, abnormal equipment damage and the like. In the prior art, part of deck boards are used for improving stability by adding a structural vibration damper, for example, a tuned mass damper (Tuned MASS DAMPER, TMD) is adopted, and TMD is used as a classical structural vibration damper and is widely applied to the fields of construction, bridges, aviation and the like. The TMD achieves a vibration damping effect by coupling a set of additional masses to the main structure through elastic and damping elements that produce a reverse phase response with the main structure at a particular frequency, thereby absorbing the vibrational energy of the main structure. However, the traditional TMD can only realize vibration reduction in a certain direction, so that the suspended walking board is difficult to perform multidirectional vibration reduction, and the TMD is mostly a fixed parameter type, the natural frequency of the TMD is not adjustable once designed, and the TMD is difficult to adapt to dynamic working conditions of the walking board under different vibration frequencies.
