Safe-typed combined climbing pole

Technical field

The present invention relates to the combination pole-climbing that a kind of fire-fighting is used.

Background technology

What first enforcement high-altitude rescue will solve is exactly the personnel's of speedily carrying out rescue work the problem of ascending a height, can climb up fast the danger in high-altitude and send out position, directly determining the success or not of rescue, therefore how to realize that to ascend a height be fast important research topic of rescue operation for a long time always, and the ascending tool most important thing of research beyond doubt.

The research of the current equipment of ascending a height of speedily carrying out rescue work is to motorization, high-endization development.With motor ladder, the equipment of ascending a height of the various modern times that platform lift truck is representative, mobility strong, easy to operate not only, and also accessible height is also more and more higher, and its advantage is approved by vast firefighters height.But the high price that its moving rut is up to a million, still underdeveloped concerning economy is a white elephant most local, and the equipment that has limited fire brigade uses, especially this class equipment bodily form huge, conduct oneself with dignity huge, very harsh to using area requirement, greatly restricted its combat performance.The current domestic small-sized fire-fighting ascending platform car (22 meters) of take is example, requires 10 meters of operation field radiuses, spacious smooth, ground is solid, space does not have obstruction, horizontal direction is not more than 6 meters apart from rescue target, this equipment of no person can only be an ornament.

To traditional manpower, the ascend a height research of equipment but stays cool for many years, traditional ascending tool that various attic ladders, short extension ladder are representative, its form of structure and material recent decades are almost without any improvement, these instruments all exist fatal deficiency, carry easy to operate climbing highly too low (5 meters following); Climb highly slightly high (9 meters are drawn ladder can arrive 7.5 meters) structure heavy, carry operation inconvenience; After Luoyang 12.25 fire in 2000,15 metals draw ladder equipment fire brigade, although can climb, highly extend to 12 meters, but it is more outstanding that the weight of nearly 200 kilograms and huge volume make to carry unhandy problem, and usage space has been proposed to very high request, need to by 8 people, operate and could use at the spacious smooth location that is not less than 8*12 square metre, and the complete operation time is grown (uncart in the situation of normal operating to holding up completely and approximately need 10 minutes to 20 minutes), the effect that promotes fighting capacity is very undesirable.In addition rope ladder has also been equipped by fire brigade, although solved problem easy to carry, can only be from eminence to downward-extension, and climbing effort very.

In the last few years along with the continuous quickening of socioeconomic fast development and urbanization process, there is huge variation in urban architecture, in small and medium-sized cities (town) although take local-style dwelling houses that rancher or two-story house room be primary structure form by the multi-storey building of 5-7 layer replace, in metropolis, the highrise building of tens meters, up to a hundred meters is in continuous increase, the multi-storey building of 5-7 layer remains the primary structure form of industry and civilian construction.Because the requirement that China's fire prevention standard builds to this class the face of suing and labouring of ascending a height is not strict, in addition the unreasonable and execution of urban planning is ineffective, the novel ascending tool of ladder truck and so in the suing and labouring of this class Building disaster often because place restriction cannot be used, even 15 meters of metals draw ladder, also lack scope for their abilities in many narrow and small places, because ascend a height, vehicle is expensive, the basic outfit in Small Urban of financial strain does not rise, when the above breaking out of fire in Dang Si building or plate indicates nature of danger, fire fighter also feels simply helpless.During situation particularly urgent, have to sue and labour by the free-hand climbing of building structure, physical demands is huge, dangerous high, ten meters feasible highly reluctantly below, be higherly not only full of peril, and rescue personnel's muscle power can not propped up yet, even if climbing puts in place, also flabbiness has completed the task of suing and labouring again.

Implement the responsibility that the new fire control law > > of the < < People's Republic of China (PRC) revising gives again public security fire-fighting army rescue in May, 2009, speedily carry out rescue work in high-altitude or the actual combat number of times of high-altitude relief increases greatly, high-altitude rescue more and more becomes the day-to-day work task of public security fire-fighting army, in the situation that do not ascend a height vehicle or the vehicle of ascending a height cannot use, how could ascend a height fast and simultaneously can maintain again enough rescue muscle power and become an extremely important and very urgent research topic, make especially the extremely urgent significant problem that needs solution of fire-fighting iron army.
