Vibration damping device and method for a chain freight ropeway

Abstract

The invention discloses a chain-type freight ropeway vibration attenuation device and method. The chain-type freight ropeway vibration attenuation device comprises a horizontal adjusting mechanism, a horizontal drive mechanism, a vertical adjusting mechanism, a vertical drive mechanism, a vibration signal acquisition module and a vibration controller; the vibration signal acquisition module is arranged on a chain-type freight ropeway rope carrying mechanism, and the vibration signal acquisition module is connected with the vibration controller; the vibration controller is respectively connected with the horizontal drive mechanism and vertical drive mechanism, the power output end of the horizontal drive mechanism is connected with the horizontal adjusting mechanism, and the power output end of the vertical drive mechanism is connected with the vertical adjusting mechanism; the rope carrying mechanism is arranged on the vertical adjusting mechanism, and the vertical adjusting mechanism is arranged on the horizontal adjusting mechanism. By adopting the chain-type freight ropeway vibration attenuation device, the lateral vibration energy of a rope carrying mechanism transmission chain can be greatly reduced, the excessively-large lateral vibration of the rope carrying mechanism transmission chain can be inhibited, the service life of the freight ropeway is effectively prolonged, the operation safety and reliability of the entire freight ropeway system can be improved, and the disastrous consequence can be maximally avoided.

Description

technical field [0001] The invention relates to the technical field of mountain transportation of goods, in particular to a vibration damping device and method for a chain freight cableway. Background technique [0002] Freight cableway plays an important role in material transportation, and it is one of the most efficient and economical transportation methods in mountainous areas with complex terrains, especially when cargo transportation needs to cross natural obstacles such as canyons and rivers, other transportation methods are difficult or even impossible to meet Its effect is more pronounced when requested. [0003] The freight cableway has strong adaptability to natural terrain, and has the advantages of large climbing ability, small land occupation and less damage to vegetation. Among the common engineering freight cableway types, the single-track circular freight cableway has outstanding advantages such as low construction technical requirements, low engineering co...

AI Technical Summary

Problems solved by technology

The single-line circular freight cableway for mountainous agricultural materials transportation usually uses an endless chain as the load-bearing traction cable. The cargo is hung on the load-bearing traction cable with a hook. Traction to do climbing, downhill, turning or oblique movement, the running line is complex

The ring chain has the vibration characteristics of a catenary line. During the axial movement, the chain will inevitably produce lateral vibrations in both vertical and horizontal directions. If this lateral vibration is not suppressed, it will not only lead to unstable movement service life, but also adversely affect the operational safety and reliability of the entire chain cable system, and may even cause catastrophic consequences
