A variable-diameter force-measuring cable-discharging mechanism

Abstract

A reducing force measurement cable arrangement structure comprises a left cable reel support, a right cable reel support, a cable arrangement unit, a winch cable reel rotationally connected between the left cable reel support and the right cable reel support, a cable winding speed reduction motor installed on the left cable reel support and used for driving the winch cable reel to rotate, and a reducing force measurement unit driven by the cable arrangement unit to conduct reciprocating motion. The reducing force measurement unit comprises a force measurement assembly, a clamping assembly and a cable limiting assembly, wherein the cable limiting assembly is connected with the cable arrangement unit; the force measurement assembly and the cable limiting assembly are connected rotationally; and the clamping assembly is connected with the force measurement assembly. The influence on the force measurement effect from swinging of a cable under external force is reduced; stress concentration or damage of structure members at the position where the cable enters or exits from a force measurement mechanism is avoided; it is ensured that the force measurement wrap angle does not change as the rolling diameter of the cable reel and the diameter of the cable change, so that the measurement precision is improved; and the cable can have a space large enough, so that the bending radius of the cable is ensured, the service life is prolonged, and the requirement for cable arrangement is met when the diameter of the cable is changed.

Description

Technical field: [0001] The invention relates to the technical field of winches, in particular to a variable-diameter force measurement cable arranging mechanism. Background technique: [0002] Optical fiber hydrophone line array (hereinafter referred to as: hydrophone line array) is mainly used for the detection of sound propagation, noise, reverberation, underwater acoustic characteristics, target acoustic characteristics, etc. in the marine acoustic environment. It is a modern naval anti-submarine warfare, underwater Advanced detection methods for weapon testing, offshore oil exploration and marine geological survey. In engineering use, the hydrophone array is connected to the probe ship through the photoelectric composite towing cable (hereinafter referred to as the towing cable), and the towing cable is used to realize the energy supply and signal transmission; the towing cable and the hydrophone cable are connected by the winch Array for rewinding storage and deployment co...

AI Technical Summary

Problems solved by technology

If the force measuring mechanism is fixed, there will be the following three problems: First, when the roll diameter changes and the cable swings, it will cause additional force to the force measuring mechanism, which will affect the measurement results, and at the same time the cable enters and exits the structure at the force measuring mechanism ( Such as the guide wheel, the guide wheel shaft, etc.) stress concentration, or even damage; secondly, when the diameter of the retracted cable changes, the relative position between the three guide wheels does not change accordingly, resulting in a change in the sensor force measurement envelope angle, then The tension value of the cable calculated according to the force measurement wrap angle will also change, resulting in a large measurement error; finally, because the cable needs to provide sufficient tensile strength, its diameter is large, and the required bending radius is also large. The bending radius required by the hydrophone line array is 15 to 20 times its diameter. If the relative position of the force measuring mechanism and the winch cable drum is fixed, a larger space is required to ensure the bending radius of the cable, otherwise the bending radius of the cable will be reduced. smaller, reducing its service life

Since the transmission ratio of the sprocket or gear and the screw rod is fixed during the transmission process, when the diameter of the cable changes, the cable discharge pitch of the cable discharge mechanism cannot change accordingly, so it cannot adapt to the cable discharge under the condition of variable diameter.
