Travelling type field-operation optical cable extension and retraction frame

Abstract

The invention discloses a travelling type field-operation optical cable extension and retraction frame, and relates to the technical field of field operation equipment. The travelling type field-operation optical cable extension and retraction frame comprises a travelling framework, wherein the bottom of the travelling framework is equipped with travelling wheels, and the top of the travelling framework is equipped with a pull rod for grip; a left cable tray supporting shaft and a right cable tray supporting shaft for mounting an optical cable disc roll are arranged on the travelling framework; the left cable tray supporting shaft and the optical cable disc roll can synchronously rotate; the travelling wheels are in transmission connection to a gear commutator through a clutch; the gear commutator is in transmission connection to the left cable disc supporting shaft, and the rotation direction of the left cable tray supporting shaft can be changed by reversing, so that the optical cable disc roll can realize positive rotation or negative rotation; and a clutch handle which is connected to the clutch and is used for controlling the clutch to achieve separation and reunion is arranged on the pull rod. The travelling type field-operation optical cable extension and retraction frame disclosed by the invention can be dragged to move forwards, and power is provided by rotation of thetravelling wheels, so that extension and retraction action of the optical cable disc roll is realized, and therefore, paving and recycling operation of the optical cables can achieve the effects of not using electric energy and greatly relieving body burden of operation staff.

Description

technical field [0001] The invention relates to the technical field of field operation equipment, in particular to a walking type field optical cable retractable rack. Background technique [0002] The operation of field optical cable retraction is an important task in field operations. Combatants usually carry optical cables on their backs or move them quickly by hand to achieve rapid laying or recovery of optical cables. The volume has considerable weight, so for the combat personnel, its body has to bear a greater burden. [0003] Chinese patent CN208008170U discloses a cable winch with a cable arrangement device, which is used for cable output during field emergency operations. It can be installed on a mobile power supply vehicle to automatically and evenly wind the cable on the cable winch. When unwinding the cable, it is necessary to rely on electric energy to provide power for rewinding. In some extreme situations where the vehicle is out of control or the power syst...

[0003] Chinese patent CN208008170U discloses a cable winch with a cable arrangement device, which is used for cable output during field emergency operations. It can be installed on a mobile power supply vehicle to automatically and evenly wind the cable on the cable winch. When unwinding the cable, it is necessary to rely on electric energy to provide power for rewinding. In some extreme situations where the vehicle is out of control or the power system is damaged, the unwinding equipment will fail, which will cause the cable laying operation to be unable to proceed normally. It is a fatal hidden danger for field operations or emergency operations. In addition, even if the operation is carried out under normal conditions, the use of this device not only requires additional installation and positioning structures on the vehicle, which increases the cost and occupies the space of the vehicle, but also When some optical cables are laid irregularly or blocked, it will hinder the recovery of the cables and affect the efficiency of the take-up
