Description

Technical Field

[0001] The utility model relates to the technical field of emergency equipment, in particular to a multifunctional and portable emergency rescue equipment. Background Art

[0002] In natural disasters such as earthquakes, windstorms, floods, and wars, bridges and roads are washed away and destroyed, and mountain communities become "isolated islands", making emergency relief difficult, and it is also difficult to transport personnel and relief supplies into the disaster area. The roads in mountain communities are rugged and large rescue equipment cannot reach them. During emergency rescue, personnel and small rescue vehicles need to overcome obstacles such as mountain streams, ditches, steep slopes, and ground fissures, and sometimes they have to overcome special obstacles such as high power grid walls and muddy swamps. Such difficulties and obstacles require a variety of traditional support equipment, which is difficult to equip in time and inconvenient to carry. The efficiency of use is low and does not fully meet the needs of emergency rescue and military operations.

[0003] At present, bridges have a single function and do not take into account the needs of personnel and light vehicles passing through and other diverse functions. Steel temporary bridge components are heavy and cannot be quickly transported and installed by humans. The cement culvert creek bottom temporary road built in the existing bridge breaking incident takes 3 to 7 days to complete, and the steel temporary bridge takes 1 to 3 weeks to open. The timeliness is often too slow and requires mechanical equipment to assist in the erection. The existing carbon fiber composite lightweight bridge technology solution has a light structure, a single function, a small span, weak environmental adaptability, a complex joint structure, unstable quality, low reliability, and poor economy, and has not yet formed a mass product application. Utility Model Content

[0004] In view of this, the utility model provides a multifunctional and portable emergency rescue equipment, which can be manually carried and erected, has various functions, and can be combined into various forms.

[0006] A multifunctional light emergency rescue equipment, including a ladder structure beam unit, a fixing pin, a bridge deck module, a plug pipe, a stay, a horizontal cable, a diagonal cable, a worm gear articulated joint, a platform vehicle and a waterproof cloth;

[0007] More than one ladder structure beam unit is plugged in and fixed by fixing pins to form ladder structure beams of different lengths as bridge deck bearing beams or straight ladders or slide rails; the platform vehicle is used in conjunction with the slide rails;

[0008] The ladder structure beam is combined with one or more of the bridge deck modules, the intubation pipes, the struts, the flat cables, and the inclined cables to form a pedestrian beam bridge, a vehicle beam bridge, a pre-stressed arch structure pedestrian bridge, a pre-stressed arch structure vehicle bridge, a string structure pedestrian bridge, and a string structure vehicle bridge;

[0009] The ladder structure beam is combined with the worm gear hinge joint to form a herringbone ladder or a rescue derrick, as well as a special ladder for climbing over obstacles;

[0010] The ladder structure beam is laterally erected on the dam and fixed vertically in conjunction with the insert pipe, and a waterproof cloth is laid on the surface to form a flood-prevention water retaining wall.

[0011] Beneficial effects:

[0012] 1. The utility model has a simple structure and light weight. The ladder structure beam units can be easily assembled into ladder structure beams of different lengths to be used as bridge deck bearing beams or straight ladder slide rails. It can also be combined with other components to form different types of bridges, equal and unequal height herringbone ladders or derricks, and special ladders for climbing over obstacles. It can also be used to lay temporary access roads in swamps and to build flood control retaining walls. It has diverse functions, strong environmental adaptability, and wide applications.

[0013] Secondly, the ladder structure beam can adapt to the coordinated work of multiple inlays, and can be economically combined according to the span length of the bridge, whether it is for people or light vehicles, etc., so that both people and small vehicles can pass through. By erecting bridges of different lengths and widths and combining them in the optimal structural form, the versatility and matching of the multifunctional modular structure can be achieved, meeting the requirements of economic applicability.

[0014] 2. The utility model is simple to assemble and set up, and only a few people can complete the setting up task. It can be deployed in advance to disaster-prone areas or delivered to disaster victims by helicopter for self-rescue. The two-way action of rescue forces inside the disaster area and outside greatly improves the rescue efficiency, effectively grasps the golden rescue moment, and helps the people in the disaster area to evacuate urgently or go out for medical treatment to get through the most difficult moments.

[0015] 3. The utility model adopts a lightweight structural design, and the foam aluminum plate is wear-resistant and drop-resistant, has good weather resistance, is reusable, and has good economy.

[0016] 4. The equipment of the utility model can be carried and erected manually. The time of manual assembly and erection of the bridge is about 10-15 minutes, and the installation is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
