Spring energy storage type ejection traction device

Abstract

The invention provides a spring energy storage type ejection traction device which comprises a bottom rack, an ejection structure, an energy storage structure and a traction structure, and the energystorage structure comprises a spring box, a spring and a spring pressing rod; the traction structure comprises a traction device, a traction rope and a guide wheel. The bottom of the fixed pulley boxis mounted on the rack; the bottom of the movable pulley box is connected with the tops of the two supporting bases, the two supporting bases are installed on the two linear guide rails respectively,and the bottoms of the two linear guide rails are installed on the rack. The compression spring and the spring pressing rod are respectively arranged in the large spring box hole; the left traction rope and the right traction rope extend out of the left traction device and the right traction device respectively, bypass the fixed end left guide wheel and the fixed end right guide wheel, are guidedby the fixed pulley and the movable pulley and bypass the movable end right guide wheel and the movable end left guide wheel to be connected with an arresting device of an arresting object. Pulley blocks are adopted for traction, double-layer compression springs are used for storing energy, rapid ejection and unfolding in the horizontal direction are achieved, normal work of the dragged arrestingdevice is guaranteed, and the device is simple in structure and convenient to maintain.

Description

technical field [0001] The invention relates to a spring energy storage type ejection traction device, which is mainly used for providing arresting net expansion and recovery in the arresting device for arresting falling objects on the water surface, and belongs to the field of marine engineering equipment. Background technique [0002] At present, with the continuous development of water surface operation technology, the tasks of high, medium and low altitude operations are constantly increasing, accompanied by underwater and surface test tasks. When hoisting objects, aerial test vehicles, and underwater launch test objects fall or are recovered on the water surface, if they fall directly into the water, they will cause damage to the equipment, and there will be difficulties in salvage, resulting in increased test costs and failure to collect test data. [0003] The existing water arresting net devices are mostly used for interception and recovery of UAVs, dredging and sepa...

AI Technical Summary

Problems solved by technology

At present, most of the arresting net devices used on the water surface to arrest falling objects in the air use compressed gas energy storage to realize the deployment of the arresting net. The deployment distance of the arresting net is short and it is difficult to recover the arresting net.
