The invention belongs to the technical field of emergency rescue, and particularly relates to a line throwing gun for ship lifesaving and fire fighting, which comprises a fixed seat and a gun body, a support frame is rotatably connected to the fixed seat, the gun body is rotatably connected to the upper end of the support frame through a rotating seat, and a high-pressure gas cylinder is mounted on the gun body. The output end of the high-pressure gas cylinder is communicated with the interior of the gun body, a piston is slidably connected to the interior of the gun body in a sealed mode, a claw hook is fixedly connected to the piston, a rescue rope is connected to the claw hook, and a take-up mechanism used for storing the rescue rope is fixedly connected to the gun body. The sliding resistance of the sealing sliding block in the arc-shaped barrel can be increased through damping liquid, then the resistance of the gun body rotating on the supporting frame is increased, when a rescue rope is thrown out, the shaking of the gun body caused by the counter-acting force of high-pressure gas is greatly reduced, the rescue rope can be evenly and orderly wound around a take-up roller through the take-up mechanism, and the rescue rope can be conveniently taken up. And the problems of winding and knotting are avoided.
本发明属于紧急救援技术领域,尤其是涉及一种船舶救生消防用抛绳枪,包括固定座和枪体,所述固定座上转动连接有支撑架,所述枪体通过转动座转动连接于支撑架的上端,所述枪体上安装有高压气瓶,所述高压气瓶的输出端与枪体内部连通,所述枪体内密封滑动连接有活塞,所述活塞上固定连接有抓钩,所述抓钩上连接有救援绳,所述枪体上固定连接有用于对救援绳收纳的收线机构。本发明可通过阻尼液体可增大密封滑块在弧形筒内的滑动阻力,进而增大了枪体在支撑架上转动时的阻力,在救援绳在抛出时,大大减小了因高压气体反作用力造成枪体的抖动,通过设置收线机构,便于救援绳均匀、有序的卷绕在收线辊上,避免发生缠绕打结的问题。
