Airbag launching poppet

Abstract

The invention discloses an airbag launching poppet. The airbag launching poppet comprises a bag body, buffering extension plates and toggle plates, wherein a bag head is arranged at one end of the bagbody and an inflation head is mounted at one end of the airbag; a sliding groove is formed in the middle of the top of the bag body; a sliding plate is movably connected with the upper side of the sliding groove; an arc-shaped baffle plate is fixed at one end of the sliding plate; a first rubber blanket is stuck to the tops of the arc-shaped baffle plate and the sliding plate; the first rubber blanket is connected with the bottom end of a ship body; the buffering extension plates are symmetrically arranged at two ends of the ship body; the tops of the buffering extension plates are connectedwith the toggle plates; a mounting head is arranged at ends of the toggle plates; the top of the ship body is fixedly connected with a mounting groove corresponding to the mounting head; a first clamping groove is formed in the inner side of each buffering extension plate and a second clamping groove is formed below each first clamping groove. According to the airbag launching poppet disclosed bythe invention, the buffering extension plates and the toggle plates are arranged; the buffering extension plates are symmetrically arranged at two sides of the ship body, so that the whole width of alaunching end of the ship is increased, the block coefficient of the large-size ship is increased and the safety of launching is improved.

Description

technical field [0001] The invention relates to the technical field of ship launching equipment, in particular to an airbag launching bracket. Background technique [0002] Airbag launching refers to the method of launching ships or other heavy objects on special marine airbags and moving them from land to water. Airbag launching has low requirements for launching ramps and a large tolerance for launching water levels. Compared with traditional slide-type launching, track-type launching, dock launching and other launching methods, it has the advantages of economy and convenience. At present, small and medium-sized shipbuilding enterprises in my country and some shipyards in Southeast Asian countries generally use airbag launching ships. The process is convenient to use, strong in versatility, wide in application and relatively low in cost. It is mainly used for ships with a square coefficient greater than 0.8, and it is more risky to use for large ships with a small square...
