Lifting type expansion square cabin

Abstract

The invention belongs to the technical field of square cabins, and particularly relates to a lifting type expansion square cabin. The lifting type expansion square cabin comprises a fixed cabin, a lifting cabin, a lifting guide rail and a jacking mechanism, the fixed cabin and the lifting cabin are each of a rectangular hollow structure, the small lifting cabin is embedded in the large fixed cabin, the lifting cabin is movably connected with the fixed cabin, and the lifting guide rail which is vertically arranged is arranged between the fixed cabin and the lifting cabin. Under the action of the jacking mechanism, the lifting cabin can vertically lift relative to the fixed cabin along the lifting guide rail to adjust the space in the square cabin, the lifting cabin is small in size and less in weight, the requirement for the jacking capacity of a jacking device is not high, jacking energy consumption is low, stability is high, the anti-explosion capacity is high, structural connection is reliable, the strength is high, and meanwhile the bearing capacity under the complex marine transportation condition is achieved.

Description

technical field [0001] The invention belongs to the technical field of shelters, in particular to a lift-type extended shelter. Background technique [0002] The extended shelter is based on the ordinary shelter, through the structural design and the design of the expansion mechanism, it has the same transportation performance as the ordinary shelter when it is recycled, and can provide a larger working space when it is unfolded to meet different functional requirements. There are many types of extended shelters, the common ones are left and right extended flap-type extended shelters, pull-out extended shelters and vertically extended extended shelters. The existing vertical lifting extended shelters are installed outside the fixed cabin. For large elevator cabins, the elevator cabin can be vertically lifted and expanded through the transmission mechanism, push rod mechanism, control structure and other lifting devices. When this kind of shelter is expanded, the elevator cab...

Problems solved by technology

There are many types of extended shelters, the common ones are left and right extended flap-type extended shelters, pull-out extended shelters and vertically extended extended shelters. The existing vertical lifting extended shelters are installed outside the fixed cabin. For large elevator cabins, the elevator cabin can be vertically lifted and expanded through the transmission mechanism, push rod mechanism, control structure and other lifting devices. When this kind of shelter is expanded, the elevator cabin covered by the fixed cabin needs to be lifted entirely. Due to the large volume of the elevator cabin, The weight is heavy, the lifting capacity of the jacking device is high, and the energy consumption of the jacking is also high. At the same time, due to the use of a large lifting shelter and a small fixed shelter, the stability is poor, and it does not have the explosion-proof ability to resist impact loads. The existing vertical lifting extended shelters are mainly vehicle-mounted, relying on the vehicle chassis as its supporting platform, generally transported by road or rail, and do not consider the carrying capacity of the shelter in the complicated case of sea transportation
