Description
Technical field
The utility model relates to mechanical equipment technical field more particularly to a kind of mechanical type anti-fall devices.
Background technique
With global evolution, location difference, also there is various requirement to high-altitude operation vehicle, meets each of client from every side
Kind demand.
1. hugeization
With the continuous improvement of Chinese Urbanization level, China's urban high-rise building quantity is sharply increased, and the height of building is not yet
Increasing disconnectedly, this just produces demand to big height high-altitude operation vehicle, thus, the needs of in order to meet domestic market and the common people,
The design that will necessarily go into overdrive production big height high-altitude operation vehicle.
2. lightweight
The self weight of high-altitude operation vehicle product boom system directly affects high-altitude operation vehicle operation amplitude and stability etc., with
Further investigation of the people to high-altitude operation vehicle boom system, people have certain understanding to the optimization of jib structure,
This makes people when design produces cantilever crane, and structure and section can more rationally, so that cantilever crane own wt can drop
It is low.
Carbon fiber arm support structure, so that cantilever crane weight saving 40%, not only greatly reduces cantilever crane weight, but also make
The cantilever crane service life is improved, and illustrates the appearance of new material, and the lightweight of high-altitude operation vehicle boom system will necessarily be brought to change
Leather.
3. multifunction
Currently, high-altitude operation vehicle other than equipped with some aerial lift devices, is generally further equipped with fire pump, fire-fighting
Fire-fighting equipments such as water pot, while some overhead escape devices can also be configured, such as high altitude escape bag, to realize height rescue, always
It, following high-altitude operation vehicle will be the multi-functional high-performance Operation Van in one.
4. seriation
Seriation is undoubtedly the important trend of high-altitude operation vehicle development.This is for enterprise's ability to ward off risks, from generation
From the point of view of boundary's range, its product system is all done step-by-step such as the U.S. spy's Rex (Terex) company in many famous engineering machinery companies
Columnization form the product of various different sizes.Because of the limited life cycle of single product, its ability to ward off risks is very low.
And the seriation of product, the R&D cycle of product can be effectively reduced, thus, domestic high-altitude operation vehicle is inevitable towards seriation
Direction is developed.
5. intelligent
With the continuous development of control technology, high-altitude operation vehicle has gradually appeared automatic leveling, visualized operation, intelligence peace
The intelligent functions such as full operation, wireless remote control and long-range monitoring.
China's aerial work platform industry development has a high potential, at least 5-10 times of growing space.China's high altitude operation
Platform product is not widely used, and a large amount of high altitude operation substitute still to use based on scaffold, or with fork truck, under a few cases
Even achieve the purpose that high altitude operation with one platform frame of installation at the top of crane.Its reason is domestic aerial work platform
Develop later, domestic market is not high to industry understanding degree, and relevant laws and regulations are also unsound, objectively hinders the development of industry
Grow.According to incompletely statistics, the aerial work platform in China market in 2016 is about 4-5 ten thousand, and leased equipment city of the U.S.
Field ownership has had more than 560,000 aerial work platforms, is 11-14 times of China.U.S.'s aerial work platform ownership per capita
Ten thousand people every more than 18, European about 8.2 every ten thousand people of ownership per capita are higher than China ownership 0.3 every ten thousand people about 20- per capita
60 times.About 3.2 every hundred million dollars of U.S.'s aerial work platform product permeability (the ratio between equipment number and GDP), European products seep
Saturating 1.98 every hundred million dollars of rate, is higher than 0.34 every hundred million dollars about 5-10 times of Chinese products permeability.It is American-European to mark, no matter from total
From the point of view of ownership, per capita ownership or product permeability, at least there is Chinese high-altitude in Chinese aerial work platform market future
At least there is 5-10 times of growing space in job platform market future.
The demand of China's aerial work platform will be presented and be grown at top speed.With the development of economic construction of China, high-altitude is made
The expansion of industry platform application range and popularity rate will be continuously improved, and the demand of aerial work platform just gradually expands.China is
Primary destination as developed country's industry profession in globalization process, currently, the America and Europe such as Terex, JLG enterprise is in China
It sets up production base and goes into operation, and plan covers China with this and Asian market, China are expected to become side by side with US and European
The big sales region of aerial work platform manufacturing industry most important three.
This simultaneously, the manufacturing enterprise in China native country has also been obtained considerable by the digestion to advanced foreign technology and absorbing
Development.Zhejiang your kind effort, capital heavy industry, Hunan Xing Bangdeng interior-capital-enterprise are emerged, product has competing on the same stage with Zoomlion
The level striven, Xu Gong, Zhong Lianchong section, Liu work and casual labourer are also gradually laid out.It is shown according to finding, Chinese high altitude operation machine
Tool market 2006-16 annual average compound growth rate about 27%, 2011-16 annual average compound growth rate about 33%, 2013-16 is compound every year
Growth rate about 44%, it is contemplated that for 2017 end of the year China's aerial work platform sales volumes at 1.7 ten thousand or so, year-on-year speedup is high up to 50%
Working platform ownership will be more than 50,000.
Speed difference catching device can lock dropped object apart from interior fast braking limiting, and be suitable for cargo hoisting, protect ground
The life security of operator and the damage for being hung workpiece object.When suitable for preventing from being hung workpiece accidental falling when overhead traveling crane lifting
Security protection, the life security of ground handling operator can be effectively protected and hung the damage of workpiece object, be applied to metallurgy
Automobile manufacture, petrochemical industry, engineering construction, electric power, ship, communication, pharmacy, bridge equal-height position Work places.This product is
A part of the system, the system of fall arrest are as follows: vertical life system and horizontal life system.The comparison of horizontal life system
Extensively.
