Embodiment Construction

[0015] Such as figure 1 As shown, the airborne winch 1 is used as the power source on the aircraft, and the control system retracts and unwinds the steel wire rope 2 to drive the load 5 to perform retracting and unwinding motions. In order to measure the tension of the winch wire rope, a force measuring device 3 is installed on its transmission route to measure the tension of the wire rope As the control and display parameters of the control system, the fixed pulley 4 can be set according to the needs of the cable transmission line.

[0016] The structure diagram of the wire rope tension measuring device is as follows: figure 2 , comprising bracket, front guide wheel 6, force measuring wheel 7, rear guide wheel 8, force sensor one 9 and force sensor two 10; front guide wheel 6 and rear guide wheel 8 are installed on the body structure by bracket, force measuring wheel 7 There is a movable bracket, and the front guide wheel 6, the force measuring wheel 7 and the rear guide wh...

Abstract

The invention belongs to an airborne winch control technology, and specifically relates to an airborne steel wire rope tension measuring device. Ordinary steel wire rope tension measurement is usually carried out using a servo type measuring device fixed on a steel wire rope, which can hardly meet the requirement of winch control system signal measurement and feedback. In test machine modification, in order to make the load of an airborne winch constant, there is a need to accurately measure the tension of a steel wire rope. The airborne steel wire rope tension measuring device, which is composed of a fixed pulley group and a force sensor, is used to detect the tension of an airborne winch steel wire rope in real time. The device can be easily modified on an aircraft or helicopter, and can be integrated inside a winch. Double-redundancy design of the force measuring function can be easily achieved. Optimal match between the range of the sensor and the tension of the steel wire rope is achieved. Thus, the accuracy of force measurement is improved.

Description

technical field [0001] The invention belongs to the airborne winch control technology, in particular to an airborne wire rope tension measuring device. Background technique [0002] Ordinary wire rope tension measurement generally uses a follow-up measuring device fixed on the wire rope, which is difficult to meet the signal measurement and feedback requirements of the winch control system. In the modification of the testing machine, in order to control the load of the winch to be constant, it is necessary to accurately measure the tension of the wire rope. The follow-up measuring device is difficult to meet the requirements of on-board use. A force-measuring device consisting of a fixed pulley block and a force sensor is specially designed to solve the problem of wire rope tension measurement of the on-board winch. Contents of the invention [0003] The invention provides an airborne steel wire rope tension measuring device composed of a fixed pulley block and a force se...
