A vertical adjustment vibration damping device and method for a chain freight ropeway

Abstract

The invention discloses a vertical-adjustment vibration-reduction device and method of a chain freight cableway. The device comprises a vertical adjustment mechanism, a vertical driving mechanism, a cable supporting mechanism, a vibration signal acquisition module and a vibration controller. The vertical adjustment mechanism comprises an adjustment gear and an adjustment toothed bar which is in meshed connection with the adjustment gear, the vertical driving mechanism is installed at one end of a gear shaft of the adjustment gear, and the adjustment toothed bar is vertically installed on the cable supporting mechanism. The bottom of the adjustment toothed bar is fixedly connected with the cable supporting mechanism, the vibration signal acquisition module is installed on the cable supporting mechanism, the vibration controller is installed on the vertical driving mechanism, and the vibration signal acquisition module is in signal connection with the vibration controller. According to the method, after the controller receives and processes vibration signals of the load end of the cable supporting mechanism, the vertical adjustment mechanism is driven to move, vertical adjustment is carried out on the cable supporting mechanism, and vertical adjustment of vibration of the chain freight cableway is achieved. According to the chain freight cableway vertical-adjustment vibration-reduction device and method, service life of the chain freight cableway can be prolonged effectively, and safety and reliability of operation of a whole chain freight cableway system are improved.

Description

technical field [0001] The invention relates to the cargo transportation technology for mountain transportation, in particular to a vertically adjusting and damping device and method for a chain cargo cableway. Background technique [0002] Aerial freight ropeways are one of the best means of transporting goods under complex terrain conditions. Freight ropeways can be divided into two types: single-line circulation and double-line circulation. Among them, the single-line circulation has more advantages than the double-line circulation in terms of construction technical requirements, project cost and damage to the surrounding environment. It has become the current mountain transportation Equipment research hotspots. The single-line circular freight ropeway usually uses a steel wire rope or an endless chain as a load-bearing traction cable. The cargo is hung on the circular traction cable with a hook. .

AI Technical Summary

Problems solved by technology

[0003] The single-line circular freight cableway for mountain transportation is built on the mountain, and the operation route is complicated. When climbing, descending, turning or oblique movement, the cable chain will be damaged due to the influence of self-excited vibration and forced vibration during axial operation. The cableway itself has lateral vibration. If this lateral vibration is not suppressed, it will not only reduce the service life, but also have an adverse effect on the operation safety and reliability of the entire cableway system, and may even cause catastrophic consequences.
