A hatch system for opening and closing the heat preservation cabin of a transport vehicle

Abstract

The invention relates to a hatchcover lifting and locking system for a transportation vehicle insulated cabin. A hatchcover comprises a left side cover, a left top cover, a right side cover and a right top cover; the hatchcover lifting and locking system comprises a left hatchcover lifting and locking unit and a right hatchcover lifting and locking unit. The left hatchcover lifting and locking unit comprises a first supporting pillar, first connection rods, a first supporting lug, first turning-over arms and a first electric cylinder; the right hatchcover lifting and locking unit comprises a second supporting pillar, second connection rods, a second supporting lug, second turning-over arms and a second electric cylinder. The hatchcover lifting and locking system has the advantages of being simple in structure, easy to control, high in reliability and low in hatchcover-lifting height; the hatchcover can be turned over and folded synchronously; rapid hoisting and transshipment of cargoes are facilitated, the hatchcover lifting and locking system has good concealment, and hiding and camouflage of the hatchcover are facilitated.

Description

technical field [0001] The invention relates to a linkage mechanism, in particular to an opening and closing hatch cover system for the heat preservation compartment of a transport vehicle. Background technique [0002] In the military and aerospace fields, transport vehicles usually need to be equipped with thermal insulation cabins to provide a good temperature, humidity and mechanical environment for special cargo such as bullets / arrows. As an important part of the thermal insulation cabin, the hatch cover should have the function of opening and closing, so that when it is opened, it can provide an entrance and exit for hoisting goods such as bullets / arrows, and when it is closed, it can provide a closed space for storage and transportation of goods. The existing insulation hatch covers mainly have the following two structures: single-piece hatch cover, which realizes the opening and closing function mainly through the flipping of the hatch cover. Since the hatch cover ca...

AI Technical Summary

Problems solved by technology

The existing insulation hatch covers mainly have the following two structures: single-piece hatch cover, which realizes the opening and closing function mainly through the flipping of the hatch cover. Since the hatch cover cannot be folded, the opening height is too high, which cannot meet the requirements of fast lifting and reloading of goods. Requirements; Flip first and then fold the hatch cover, which requires two sets of driving mechanisms to flip and fold the cover respectively, resulting in more drives and more difficult control, which affects the reliability of the entire insulation cabin system

And the driving mechanism of the existing hatch cover usually arranges the connecting rod on the outside of the hatch cover, which is not conducive to stealth camouflage
