Design and Experimental Research of Metal Mesh Pneumatic Tying Device with High Tension
摘要
Abstract
In order to achieve the high pre-tensioned stress and pre-tensioned stress diffusion required by the high pre-tensioned stress bolting system, the high tensioning metal mesh pneumatic tying device was independently researched and developed and the device was mainly composed with the main cylinder assembly, the twisted wire cylinder assembly, the staple mechanism, the push wire mechanism and the twisted wire mechanism. The optimal design parameters of the network U-pin length of 35 mm, wire feed thrust of 2 kN and rotation torque of 6 N·m are analyzed and determined. Experimental results show that high tension pneumatic networking device can provide tension force of about 0.13 kN. The strength of the network is 61.5 % higher than that of artificial network, and it can reach 91.3 % of the strength of the entire network.关键词
