Description
Technical field
The utility model relates to a kind of anti-falling safe pick-up unit, is specifically related to a kind of pick-up unit of the performance of the anti-falling safe for detection of transmission line of electricity.
Background technology
In recent years, being accompanied by the China Power developing steps constantly accelerates, China Power Grids is also developed rapidly, network system working voltage grade improves constantly, network size also constantly enlarges, the whole nation has formed Northeast China Power Grid, North China Power Telecommunication Network, Central China Power Grid, East China Power Grid, Northwest Grid and 6 large area electrical networks transprovincially of south electric network, and has basically formed complete long distance powedr transmission Net Frame of Electric Network.Power grid construction has become the main direction of China's power construction, and during " 12 ", China's electric grid investment scale continuous expansion will be built up unified strong intelligent grid to the year two thousand twenty comprehensively, the preliminary target that realizes building world-class electrical network.Development construction along with China's electrical network; maintenance and the testing of electric power pylon become more and more important; in the process of current domestic transmission line pole tower operation maintenance high-altitude mobile operational process; the staff needs necessary anti-falling from high altitude safeguard measure; existing salvo and scheme can meet in the mobile operational process process of high-altitude the requirement for safeguard protection basically, thereby have realized the safe closed loop protection of work high above the ground.
The transmission line high-altitude mobile operational process, mainly refer in iron tower of power transmission line and the enterprising pedestrian's displacement body of cement pole, upstream or downstream activity.For steel tower; general dependence arranges the pin nail or cat ladder carries out displacement; for cement pole; the general ascending tool that relies on carries out displacement, and in moving process, requires falling proof device to realize real-time, omnidistance protective effect, and no matter the operating personnel carries out the high-altitude mobile operational process on steel tower or cement pole simultaneously; all must accomplish spiritual high concentration; foot-operated real, hand is grabbed surely, climbs coordination and prevents the burst hidden danger that may occur.
In China; except power industry also has a lot of other industries; industries such as building, mine, municipal administration, railway, oil, chemical industry, metallurgy, post and telecommunications and high-altitude service sector all exists work high above the ground; but these industries also have a lot of not enough to the research of anti-falling overhead; basically be mainly emphasize correctly to use of seat belts, safety net; safety barrier is set and avoids high-rise working etc., do not emphasize the protection in moving process.
On current domestic transmission line of electricity, falling proof device substantially all has been installed, falling proof device is as the accessory of iron tower of power transmission line, can effectively prevent line maintenance, the construction operation personnel are upper, personnel's falling accident occurs in lower shaft tower process, reliable and practical security protection equipment is provided in climbing the shaft tower process for the circuit homework personnel, the falling proof device standard has been installed operation behaviour, promoted operation field safety construction level, although increased the line construction cost, but very big safety guarantee has been arranged in personal safety, also fully demonstrated the spiritual civilization construction theory that people-oriented, iron tower of power transmission line is installed falling proof device and is had far-reaching social effect.
By capital construction section of State Grid Corporation of China, exchange Ministry of Construction's results that the personal investigation's of relevant unit part economizes 11 fortune inspection companies of taking the lead for twice and show, falling proof device all has been installed on the extra high voltage line steel tower.Wherein, the southeast-Nanyang, 1000kV Shanxi-Jingmen exchanges engineering 1284 cover falling proof devices is installed altogether, economizes fortune inspection company by Shanxi, Henan, 3, Hubei and is responsible for working service; ± 800kV installs 3149 cover falling proof devices altogether to family dam-Shanghai DC engineering, economizes fortune inspection company by Hubei, Sichuan, Chongqing, Hunan, Anhui, Zhejiang, Jiaxing, Jiangsu, 9, Shanghai and is responsible for working service.According to 11 investigation statisticses of economizing fortune inspection company and Shandong District, draw, in actual moving process, falling proof device is used 1～3 time every year on average, generally step in tower inspection, monitoring and maintenance process and all need to use falling proof device, this just requires the equal claimed condition of these falling proof devices good.
But some problems have in use also appearred in these falling proof devices of installing and using.For example, self-locking device slides not smooth; Guide rails assembling or the operation a period of time after, distortion, distortion, not straight easily appear, cause self-locking device not pass through smoothly; Some steering gear turns to dumb, and the self locking on partial circle device is heavier, increases the workman and bears a heavy burden and labor capacity; On some tower, exist the K point to be difficult for passing through, the potential danger of falling is arranged; Steel strand wires type self-locking device, through each support interval, tearing open and move, install, is used inconvenience, has reduced operating efficiency; In the sleety weather situation, the rail mounted falling proof device is usually because track icing and easy-clear not, in the serious situation of icing, and the situations such as cisco unity malfunction.
Although the domestic research at falling proof device and use are also in the starting stage, due to actual needs, number of times and frequency that falling proof device is used are more and more frequent, and the safety problem of falling proof device highlights important.In order effectively to detect the performance of falling proof device, the inventor is according to normal shaft tower falling proof device performance test index, through long-term observation, research, find, designed a kind of test unit that detects iron tower falling-proof dropping control device performance, for the performance of dissimilar falling proof device is tested, can meet the requirement of in " falling-preventing device for pole tower operation " Q/GDW162-2007 standard, dead load, impact load etc. being tested simultaneously; Thereby guarantee falling proof device not failure and yield deformation in 15kN dead load, 100kg load impulse test situation.
