A cabin synchronous retractable device

Abstract

The invention discloses a cabin body synchronous retractable device, which comprises two retractable mechanisms, the two retractable mechanisms are respectively arranged on both sides of the cabin body, the retractable mechanism includes a fixed seat, a first connecting rod, a second connecting rod Rod, the third connecting rod and the drive cylinder, one end of the first connecting rod and the second connecting rod are all hinged on the fixed seat, the other ends of the first connecting rod and the second connecting rod are all hinged on the cabin body, the first connecting rod The length of the rod and the second connecting rod are equal and arranged in parallel, one end of the driving cylinder is hinged on the fixed seat, the other end of the driving cylinder is hinged to one end of the third connecting rod, and the other end of the third connecting rod is hinged to the first connecting rod or on the second link. The purpose is to provide a synchronous retracting and retracting device for the cabin to realize the rapid lowering and recovery function of the cargo cabin, facilitate the rapid loading and unloading of cargo in the cargo cabin, save costs, improve efficiency, and avoid some safety risks at the same time.

Description

technical field [0001] The invention belongs to the technical field of space launch, and provides a special mechanism for retracting and retracting a spare parts compartment, and in particular relates to a synchronous retracting and retracting device for a compartment. Background technique [0002] At present, the commonly used large-scale transportation support vehicles have mostly fixed cargo compartments or one-way erected cargo compartments. This type of cargo compartment has the following disadvantages: (1) the cargo compartment is generally higher than the ground, and the staff needs to consume manpower or labor when loading. The handling equipment lifts the goods to a certain height and then moves them into the cargo hold, which increases the labor cost of loading and also affects work efficiency; (2) When unloading, the staff also need to climb into the cargo hold or complete the unloading process through the lifting device. Time-consuming and labor-intensive; the ca...

Problems solved by technology

[0002] At present, the commonly used large-scale transportation support vehicles have mostly fixed cargo compartments or one-way erected cargo compartments. This type of cargo compartment has the following disadvantages: (1) the cargo compartment is generally higher than the ground, and the staff needs to consume manpower or labor when loading. The handling equipment lifts the goods to a certain height and then moves them into the cargo hold, which increases the labor cost of loading and also affects work efficiency; (2) When unloading, the staff also need to climb into the cargo hold or complete the unloading process through the lifting device. Time-consuming and labor-intensive; the cargo compartment is a single cargo compartment, and it is inconvenient to access the items in the middle of the cargo compartment, and the items on the outside need to be moved away to get them; (3) In the field of space launch technology, in order to meet the requirements of actual combat, it is necessary to ensure that the combat unit is accompanied by support equipment. quick maneuver

These problems have increased the labor cost of the transport support vehicle during use, and also affected work efficiency

[0003] In addition, for docks, warehouses and other cargo holds and container centralized storage places, there are often stacked cargo holds, which makes it inconvenient to take goods at higher positions, affects work efficiency, and there are safety hazards in the process of picking up goods, which may cause personnel accidents. Safety accidents such as falling and cargo falling
