With the increase of high-rise buildings, high-rise building fire accidents also tend to be normalization. High-rise building fire, particularly ultra-high-rise building fire, has become an unsolvable problem in life and workplace. The design of new embedded scalable fire rescue equipment will effectively improve the ability of high-rise firefighting and rescue, and also make some special design of the structure according to the special environment. Modeling the embedded fire rescue equipment through PTC Creo3.0 and studying the process of assembling and simulation to test whether motor function meets the design requirements and actual operational requirements or not. Introduction Since urbanization and economic development require more space, constructing high-rise building has become an effective means of saving space. Ultra-high-rise buildings in large urban agglomerations address the shortage of land, but bring the problem of fire prevention and control into a high level [1]. High-rise building firefighting faces big difficulties in water supply, gas flow which is influenced by the height, dangerous, climbing challenge, difficult to use vehicle, the radio communication signal attenuation serious, communicate blind spots and other issues [2]. High water tank to serve water, elevator evacuation are often used for high-rise building fire rescue [3]. Fire rescue mode is divided into self help and help from others. In high-rise buildings, self-help firefighting equipment mainly include: indoor and outdoor fire hydrant system, automatic alarm system, automatic sprinkler system; helping from others mainly includes the equipment of fire helicopter, firefighting robots, fire vehicles, fire guns [4]. In recent year water bomber helicopter, fire robot, fire guns also get some breakthrough [5]. In June 2002, by the Ministry of Public Security Shanghai Fire Research Institute, Shanghai Jiao tong University and Shanghai Fire Bureau shared three units of 863 project "crawler, wheeled firefighting robot" successfully developed and passed the national acceptance. Firefighting robot, also known as self-propelled water foam gun, is a combination of a variety of firefighting methods [6]. Analysis the applications of high-rise building fixed fire protection since 2000, the summary should be drawn as fixed fire fighting facilities within the high-rise building should be preferred firefighting equipment [7]. Embedded retractable fire rescue equipment is based on high-rise building fire, integrated with mechanical design and optimization, electrical system design and architecture, will achieve convenience, safety, reliability, intelligent of high-building fire rescue, then meeting the requirements of real-time monitoring and fire extinguishing. Overall Structure Design Embedded scalable high-rise building fire rescue device (Fig.2) consists of three parts: telescopic rails, fire extinguishing systems, ground remote central control system. Telescopic rails mounted horizontally in a high-rise building refuge floors, installed with extinguishing medium and scalable transport pipeline (Figure 1). Fire extinguishing system consists of control room, fire guns, fire 6th International Conference on Information Engineering for Mechanics and Materials (ICIMM 2016) © 2016. The authors Published by Atlantis Press 604 monitoring devices, gun control system, fire monitoring transmission system, the inherent power. Remote central control system consists of ground fire live image display system, the gun remote control system, extinguishing medium transport control system. When fire occurs, it can manually or automatically extend outside the building, fire extinguishing system is fixed at the end of the telescopic rails. Fire monitoring device adjust to achieve three-dimensional direction, collecting real fire screen, the information is sent wirelessly to the control room, control room send instructions to the gun control system based on radio transmission, adjusted by the gun control system to achieve precisely firefighting. Single gun perpendicular and adjacent to at least cover the scope of work for more than half the distance of two layers of refuge, horizontal single gun could cover same range with the perpendicular single gun, the working scope depends on the size and level of fire extinguishing system and the number and length of guns. Figure 1: Telescopic program diagram Figure 2: Overall Equipment Installation Diagram Telescopic cylinder design The largest travel requirement of retractable cylinder in design is 50m, initially using six telescopic cylinders, stroke of each stage 5m. During their work, it needs to extend and retract the cylinders, all levels cylinder stretch sufficient stroke in order, choose multi-stage double-acting telescopic cylinders. In the process of working, there is a large amount of compressed gas in the cylinder, after the cylinder fully extending, the cylinder will be under great bending stress, and the wall thickness of the cylinder must be reached certain requirements to ensure their normal working condition. The basic parameters of the multi-stage telescopic cylinders are in the table below: Table 1: The main dimensions of the cylinder at all levels
