Description

Technical Field

[0001] The invention belongs to the technical field of emergency rescue, and in particular relates to a modular hydraulic comprehensive rescue equipment for collapse and limited space. Background Art

[0002] During disasters such as earthquakes, mudslides, and building collapses, people are often buried. Such accident sites are often accompanied by road traffic interruptions, piles of ruins at the disaster site, and poor rescue conditions. It is difficult for large-scale demolition machinery to enter the disaster site to carry out rescue. When rescuers find buried people with the help of life detection equipment on site, they can only rescue them manually or with the help of simple handheld mechanical equipment, which is inefficient and easily causes further collapse of the building ruins on site, resulting in damage to buried people and even rescuers. Currently, most of the existing collapse rescue equipment is to build building passages through separate support columns and rods, such as a combined tunnel collapse rescue device disclosed in Chinese patent CN113356919A. An air bag is set in the accommodating cavity between the upper and lower cover plates. Under the action of the air pressure in the inflated air bag, the upper cover plate and the lower cover plate are separated from each other to prop up the collapsed objects to form a rescue cavity. According to the rescue needs, multiple rescue devices can be connected in sequence, so that multiple rescue cavities are connected end to end to form a rescue channel for rescue. The above collapse rescue devices generally have the disadvantages of low rescue efficiency, limited application space scenarios, poor flexibility, etc., especially they are not suitable for rescue in complex and narrow spaces. Therefore, in order to improve the efficiency and ability of comprehensive rescue in collapse and confined spaces, it is necessary to develop modular comprehensive rescue equipment that can build safe rescue channels, and improve the intelligence and integration level of technical equipment for collapse rescue on-site by fire rescue personnel. Summary of the invention

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] A modular hydraulic comprehensive rescue equipment for collapse and confined space, such as Figures 1 to 10 As shown, it includes a support unit 1 and a track unit 2 inside the support unit; the support unit includes a plurality of groups of channel frames 3 arranged side by side, each group of channel frames is connected in series through a connecting shaft 4, and each group of channel frames includes two crocodile-type toppers 5, which are fixed by a top connecting plate 6; the crocodile-type toppers include a base 7 and a support body 8 hinged to each other through a connecting shaft, and the angle between the base and the support body is adjusted by a jack 9; usually, the jack is arranged close to the connecting shaft, laying a structural foundation for building a wider rescue channel.

[0031] A fixing seat 10 is provided at one end of the support body away from the connecting shaft, and the top connecting plate and the fixing seat are detachably connected by a fixing member 11, which can be a screw. The ends of the two bases away from the connecting shaft are against each other, and the upper surfaces of the two bases together constitute a rescue channel; the track unit includes two track bodies 12 laid in the rescue channel, the track body includes a flexible shell 13 and a spring 14 inserted in the flexible shell, and a functional cable 15 is inserted inside the spring. Since the base and the support body of the crocodile-type top are hinged, and the track body adopts a flexible shell, and a spring with deformation ability is arranged in the shell for support, the support unit (base) and the track unit (track body) can adapt to the terrain shape and have good adaptability. In an optional embodiment, the two track bodies can be connected by a connecting rod to keep the spacing between the two track bodies stable. A fixing hole 17 is provided on the upper surface of the fixing seat. A slide groove 18 that cooperates with the extension rod of the jack is provided on the lower surface of the support body. Usually, the functional cable includes a communication cable.

[0032] In an optional embodiment, the top connecting plate includes a horizontal portion 20 and connecting portions 21 at both ends of the horizontal portion, the connecting portions are arranged obliquely downward, and are provided with connecting holes 22. Each set of channel frames constitutes a trapezoidal structural frame, and the connecting portions on both sides of the top connecting plate can better adapt to the structure of the crocodile-type headers on both sides. After being connected and fixed with the help of the top connecting plate, the overall structural stability of the channel frame is good.

[0033] A docking seat 16 is provided at one end of the base away from the connecting shaft. The cross-sectional area of ​​the docking seat is larger than the cross-sectional area of ​​the main structure of the base, and the cross-sectional area of ​​the fixed seat is larger than the cross-sectional area of ​​the main structure of the support body. In an optional embodiment, the upper end surface of the docking seat is higher than the upper surface of the base, and the lower surface of the fixed seat is lower than the lower surface of the support body. Therefore, when the support body and the base are folded, the jack can be stored in the groove between the support body and the base.

[0034] In an optional embodiment, the track unit includes a traction trolley 19, and the two track bodies are respectively connected to the two sides of the traction trolley. After the support unit is built, the two track bodies can be arranged on the inner side of the support unit with the help of the traction trolley. The traction trolley can be pulled by a traction rope, or it can be a self-powered trolley, which will not be repeated here. In a further improved solution, a functional module 20 can be installed on the traction trolley, and a crawler walking system 21 can be installed at the bottom of the trolley, which is driven by the common hydraulic system of each jack. As an example, the functional module includes an obstacle removal and demolition module and a detection module. The detection module can use an infrared visible light detection module. The infrared visible light detection module is used to detect the position of the buried personnel and the surrounding environment in real time under dark and weak light conditions, and has the function of real-time communication for survey and detection. The obstacle removal and demolition module includes a universal hydraulic shear and a demolition hammer. A hydraulic valve group 22 of a universal hydraulic shear and a demolition hammer is provided on the traction trolley. The universal hydraulic shear is used to remove the steel bars in the channel. The demolition hammer can be remotely controlled to remove and clear obstacles on the rescue channel by hammering. When working, the hydraulic system provides power to the actuator in the obstacle removal module. The hydraulic system (hydraulic station) is carried by a special fire emergency vehicle. The detection module detects the actual working conditions. The obstacle removal module can be used to remotely control the removal and clearing of obstacles on the rescue channel to ensure the smooth progress of the rescue work. The flexible track is used to remove obstacles with the front-end functional module to establish a rescue channel. The flexible track body can be installed with a transfer platform to facilitate the transfer of trapped personnel and materials.

[0035] The jack in the crocodile-type top device (by the hydraulic station of the fire rescue vehicle) transmits power through the hydraulic pipe, and with the cooperation of the micro hydraulic expander, it can be extended into the collapse search and rescue site to rescue the buried people. When laying this emergency rescue equipment, the traction trolley can be used to pull the track unit deep into the collapsed area, and then push multiple groups of channel frames in sequence, and finally use the hydraulic system to drive the jack to lift the support body, so that the crocodile-type top device supports the collapsed area to form a trapezoidal space structure. The invention creates the advantages of integrated detection communication, demolition and obstacle removal, support protection, and safe and fast transportation of personnel and materials. The remote hydraulic station is used to provide power, which can realize efficient rescue in small and confined spaces. In addition, the flexible slide rail unit is used as a transfer platform, and combined with the detection and demolition module, it can realize the integration of multiple functions such as narrow space passage and personnel search and rescue, transfer, etc., and improve the efficiency and environmental adaptability of collapse and limited space rescue. In addition, a follow-up protective plate can be installed on the track unit, that is, a protective plate 24 is installed on the track body, which can cooperate with the top device to play the role of supporting the collapsed objects.

[0036] The invention has a reasonable design, and utilizes the hydraulic station on the fire rescue vehicle to provide hydraulic power for the device traction, to push the traction trolley forward and to break and clear obstacles, and to provide hydraulic support for the rescue channel, which can reduce the size and weight of the equipment. Specifically, a support unit is formed by a plurality of groups of channel frames, which can effectively form a rescue channel with a ladder-shaped space structure, and a track body is arranged in the rescue channel to provide a necessary path for the detection equipment or the rescue equipment. The flexible track is broken and cleared with the front-end functional module to establish a rescue channel. The transfer platform 23 can be installed on the flexible track body to facilitate the transfer of trapped personnel and materials, which can improve the rescue efficiency, and has a wide range of application space scenes, good flexibility, and small limitations. It can be applied to the rescue of complex and narrow spaces. As an example, the conveying trolley and the flexible track body are attracted by the slot-type magnetic wheel and the spring steel built into the flexible track to form a compression constraint, always maintaining a pure rolling motion relationship, and having a certain anti-flipping ability. The functional cable is connected to the power and communication modules on the traction trolley to form wired communication and power supply, and the use performance is stable and reliable. In addition, in order to maintain the stability of the distance between the two track bodies, the support body can be expanded step by step through the remote hydraulic system to support large obstacles to build a safe barrier for people to escape, forming a protective channel that can prevent further collapse.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
