Problems solved by technology

However, the natural wind is a kind of random excitation, and even under a certain fixed wind level, its wind speed also changes randomly within a certain range, so the approximate calculation using the mechanical model cannot reflect the real characteristics of the hanging tank swing

Abstract

The invention discloses a wind tunnel test research device and method for swinging of a cable crane cage under influence of gale. The device comprises a wind simulating device for simulating a gale environment, wherein the wind simulating device is arranged on the side face of a swinging device, the swinging device is used for simulating the cable crane cage and being matched with the wind simulating device to simulate the swinging conditions of the cable crane cage in different wind speed grades; and the swinging device is matched with a test recording instrument for recording the simulatingtest result, and the test recording apparatus records a test result. The device can simulate the swinging condition of the cable crane cage in the gale condition, so as to provide data support for follow-up researches.

Description

technical field [0001] The invention belongs to the research field of cable crane construction, and in particular relates to a wind tunnel test device and method for studying the swing of a cable crane tank under the influence of strong wind. Background technique [0002] As the main concrete transportation and pouring machinery in the construction of arch dams in alpine and canyon areas, the cable crane has the characteristics of once erected and benefited during the entire construction period. From the analysis of its own structure, the flexible cable of the cable crane is the main part in the transportation process of the hanging tank. At the same time, considering the pouring height of the cable crane, the length of the cable can reach hundreds of meters; moreover, considering the construction environment of the cable crane, the cable The machine-hanging tanks go back and forth between the feeding platform and the dam body, which easily conflicts with the construction ma...
