Description

Quick-unfolding double-cabin-body expansion shelter for emergency rescue Technical Field The invention relates to the technical field of emergency rescue equipment, in particular to a rapid expansion type double-cabin expansion shelter for emergency rescue. Background In emergency rescue sites of earthquakes, flood disasters or sudden public health events, shelter vehicles capable of rapidly deploying and providing large-capacity working space are one of core equipment. In order to meet the trafficability of road transportation and the space requirement of parking operation, a shelter adopting a two-side stretching and expanding structure becomes a mainstream technical scheme. The shelter is folded during transportation to meet the width limit of road regulations, and is unfolded to two sides after reaching the site to obtain additional medical or command space. However, existing extended shelter technology has a difficult reconciliation between structural layout and actual use experience. Because the bottom of the shelter must retain the travelling mechanism (axle, tyre) and chassis girder, in order to ensure that the expansion shelter does not interfere with the chassis structure during retraction and extension, the existing designs generally have to design the floor position of the expansion shelter to be significantly higher than the floor position of the main shelter, or adopt a sliding rail overhead scheme. This structural compromise, which is used to avoid the chassis, directly results in an inherent step height difference between the main and expansion tanks after deployment of the shelter. In the first-aid scene of the requisite minute, the step seriously hinders the rapid barrier-free passing of the medical stretcher, the wheeled medical equipment and the emergency personnel, and often a heavy transition slope plate is additionally paved, so that the workload of unfolding and withdrawing is increased, and the potential safety hazard of tripping of the personnel is also caused. In addition, the traditional expansion shelter also has the problem of insufficient adaptability when facing the field severe environment. On one hand, if the large-span cantilever expansion structure lacks an effective bottom rigid support, the large-span cantilever expansion structure is easy to generate downwarping deformation, so that the floor is difficult to align or recover clamping stagnation after long-term use, on the other hand, the existing sealing design is focused on static water stop, and lacks a dynamic protection mechanism for the expansion process, so that rainwater, sediment or ice and snow attached to the outer surface of an expansion cabin body are extremely easy to be brought into the main cabin along with the recovery action of the cabin body, and the cleanliness or sterile environment in the cabin is damaged. Meanwhile, the power supply mode of the vehicle-mounted generator or the commercial power is simply relied on, and the energy source supply requirement of long-time off-grid operation under extreme conditions is difficult to meet. In view of the above, the invention aims to provide a rapid expansion type double-cabin expansion shelter for emergency rescue, which solves the defects in the prior art. Disclosure of Invention Aiming at the defects of the prior art, the invention provides the rapid expansion type double-cabin expansion shelter for emergency rescue, which solves the problem that the existing expansion shelter has steps (height difference) between an expansion floor and a main cabin floor due to avoiding a chassis travelling mechanism, thereby preventing emergency stretcher and wheeled equipment from realizing barrier-free rapid passing. The rapid expansion double-cabin expansion shelter for emergency rescue comprises a main cabin body, wherein a main cabin floor is arranged at the bottom of the main cabin body, hydraulic supporting mechanisms are arranged below the bottom of the main cabin body, expansion cabin bodies are symmetrically arranged on two sides of the main cabin body, expansion floors are arranged at the bottoms of the two expansion cabin bodies, guide mechanisms are arranged on two sides of the bottom of the main cabin body and used for carrying and guiding the expansion cabin body to do linear reciprocating motion relative to the main cabin body, a driving mechanism is connected between the main cabin body and the expansion cabin body and used for driving the expansion cabin body to switch between a furled state and an expanded state, the expansion cabin body is contained in the main cabin body in the furled state, and the expansion cabin body extends outwards along the guide mechanisms in the expanded state. Preferably, the guide mechanism comprises electric sliding rails which are transversely arranged on two sides of the main cabin body, and one sides of the movable seats of the two electric sliding rails are respectively and fixedly connected with two sides of the ex
