On-line detection device for shaft-sinking suspension steel wire rope

Abstract

The invention discloses an on-line detection device for a shaft-sinking suspension steel wire rope, belonging to on-line detection and monitoring equipment. The on-line detection device of a shaft-sinking suspension steel wire rope comprises a plurality of force transducers, an A / D conversion circuit, an upper singlechip, a transmission circuit, a receiving circuit, a lower singlechip, a digital display circuit, a printing circuit, an alarming circuit and an executive circuit, wherein the force transducers are installed on a hanging scaffold or a suspension template platform; the A / D conversion circuit converts a tension value analog signal into a digital signal; the upper singlechip is connected with the A / D conversion circuit; the transmission circuit is connected with the upper singlechip; the receiving circuit is installed on the ground; the lower singlechip is connected with the receiving circuit via an RS232 interface; and the digital display circuit, the printing circuit, the alarming circuit and the executive circuit are connected with the lower singlechip. After the tension value of each steel wire rope is processed by the upper singlechip and sent into the transmission circuit via each force transducer, the transmission circuit sends the signal to the ground; the signal is sent to the lower singlechip via the receiving circuit to be correspondingly processed; and then, the signal is output by the digital display circuit, the printing circuit, the alarming circuit and the executive circuit. Thus, the system has the advantages of high antijamming capability, high accuracy and complete protective functions, is easy to operate, and can ensure that the stress of the suspension wire rope is detected in real time.

Description

technical field [0001] The invention relates to an on-line detection device, in particular to an on-line detection device for sinking and suspending steel wire ropes. It is mainly suitable for on-line detection of steel wire ropes for suspension construction equipment during shaft excavation. Background technique [0002] In mine construction, especially in the excavation of shaft shafts, all construction equipment is suspended by wire ropes. The safety factor of the wire rope is directly related to the construction safety of the mine, especially when the suspension equipment is subjected to impact force or being stuck, its instantaneous value will increase exponentially, so it is very necessary to detect the force status of the wire rope. But so far there is no special testing equipment. Contents of the invention [0003] The invention provides an on-line detection device for the suspension wire rope of a shaft, which can realize the on-line detection and monitoring of ...
