The multifunctional modularized flexible cable guiding device comprises a case, a flexible cable device, a pulley device, a single chip microcomputer, a wireless communication module and an LED display screen are arranged on the case, the flexible cable device and the pulley device are provided with sensors and strain force sensors, a flexible cable reaches the flexible cable device through the pulley device, tension of the flexible cable is measured through the all kinds of sensors, and in combination with a space geometry relation, the tension and posture of the flexible cable are tested. The single chip microcomputer is used for collecting, analyzing and processing all kinds of information so as to accurately position the posture of the flexible cable, a display module is used for displaying result data on the LED displays screen in time, an alarm module is further arranged inside the single chip microcomputer, and an alarm prompt can be given in time when the tension of the flexible cable exceeds rated tension. The wireless communication module facilitates remote observation analysis and control. The modularized design is used, and in this way, installing, detaching and transporting are facilitated. The detection method is good in measuring effect, and has high practicability in the aspects of stress and angle measuring of the flexible cable.

Description

technical field [0001] The invention relates to a multi-functional flexible cable guiding device and detection method, which is especially suitable for the guidance of the flexible cable or the detection of the posture and tension of the flexible cable during the continuous direction change process of mine hoisting, flexible cable parallel mechanism, flexible rehabilitation robot and other equipment. The invention belongs to the technical field of equipment safety. Background technique [0002] As a key component of traction and load-carrying, flexible cables are light in weight, simple in structure, easy to change direction, and large in carrying capacity. Plays a vital role in the field of construction. Traditional flexible cable guides generally use fixed pulleys for guidance, which will lead to an extremely reduced working space for the flexible cable, and cannot bring out the characteristics and advantages of the flexible cable. During the on-site operation, it is affe...

Problems solved by technology

Traditional flexible cable guides generally use fixed pulleys for guidance, which will lead to an extremely reduced working space for the flexible cable, and cannot bring out the characteristics and advantages of the flexible cable. During the on-site operation, it is affected by multiple external factors, such as Due to factors such as load fluctuations and emergency changes of direction, excessive wear, jamming, and derailment will occur, resulting in mechanical fatigue of flexible steel wire ropes due to frequent force changes, and even fractures, resulting in irreparable casualties

Regarding the flexible cable guide device, the invention patent publication No. CN102627234A "A Flexible Cable Traction Device with Force Measuring Function" provides a device that can detect the dynamic tension of the flexible cable. In the working space, the tension is detected by the tension sensor. The disadvantage is that the device cannot detect the pose and shape of the flexible cable.

"A Longitudinal Capacitive Steel Wire Rope Tension Detection Method and Device" disclosed by the invention patent with the publication number CN102494828A provides a capacitive steel wire rope tension detection method and device. The distance between the upper and lower plates of the capacitor changes, so the tension of the cable can be measured by the capacitance value. The disadvantage is that the tension of the cable after it is damaged cannot be detected.
