Problems solved by technology

[0003] At present, the existing fire extinguishing equipment is equipped with a plurality of launching tubes. The piston in the launching tube is generally in a normal state. When launching, the piston will recoil. Finally, the piston of the launch tube on the market is relatively fast during recoil and re-entry, which affects the overall service life

Abstract

The invention discloses a recoil and counter-recoil two-in-one buffer damping device. During use, a piston recoils, the resistance of a second elastic device is increased, the recoil energy is absorbed, a valve limits the liquid flow speed through a reserved gap between the valve and the piston at the same time, the recoil speed of the piston is decreased, the piston conducts counter recoiling under the effect of the second elastic device after the piston recoils to the limiting position, the valve is forced to move backwards through liquid flow at the moment, the reserved gap is reduced to minimum, the liquid backflow speed is limited, the counter-recoil speed of the piston is decreased, and finally, the piston returns and resets through a first elastic device; and by means of the comprehensive effect of composite springs of the second elastic device and liquid hydraulic oil, the recoil speed of the piston is decreased, the counter-recoil speed of the piston is decreased, and therefore the movement speed of the piston is decreased.

Description

technical field [0001] The invention relates to the technical field of launching devices, in particular to a two-in-one buffering and damping device for parking, retreating and advancing. Background technique [0002] At present, the number and scale of fires are increasing year by year, which puts forward higher requirements for the performance indicators of fire fighting equipment. [0003] At present, the existing fire extinguishing equipment is equipped with a plurality of launching tubes. The piston in the launching tube is generally in a normal state. When launching, the piston will recoil. Ultimately, the pistons of launch tubes currently on the market are relatively fast during recoil and re-entry, which affects the overall service life. [0004] Therefore, how to provide a two-in-one buffering and damping device for parking, retreating and returning, so as to reduce the moving speed of the piston, is currently a technical problem to be solved urgently by those skil...
