Description
Technical field
The utility model relates to electrical-controlled lifting machine field, especially a kind of bont that is applied in the electrical-controlled lifting machine in aerogenerator maintenance, maintenance.
Background technology
Wind energy is as a kind of clean regenerative resource, more and more be subject to the attention of countries in the world, and the amount of accumulateing and huge, wind-power electricity generation is as one of current novel energy industry, because its environmental protection and energy saving development scale is advanced by leaps and bounds, it is ten hundreds of that current China nationwide has had wind power generating set, and still have the fast-developing impetus.And in such cases, how to ensure the wind-powered electricity generation unit normal operation of enormous amount, become very important problem.The mode of operation of wind-power electricity generation group and installation general layout have determined that maintenance, maintenance workload in its life-cycle are very large.In order to ensure the normal operation of wind-powered electricity generation unit, need to drop into a large amount of process special trainings, young stalwartness and veteran technical personnel and carry out normal care and maintenance.
In the process of care and maintenance, often carrying out a conventional maintenance often needs up and down several times, if wind-powered electricity generation unit maintenance round number of times can be more, because the height of tower barrel of wind generating set is all more than 50 meters, and in service work, service personnel is not only wanted oneself to climb up high tower, also need instrument and the parts back high tower of maintenance use, its labour intensity big ordinary person absolutely not can bear, to staff in muscle power with caused mentally great pressure directly to cause the decline of the rising of risk and work efficiency, repair quality.
Moreover, the technology content of wind power generating set is quite high, need to pass through special training, the technical skill personnel that service experience is abundant just can carry out maintenance, if within every ten days, safeguarded once by a unit, each technical personnel every workday can be safeguarded two units, in order to safeguard this typhoon group of motors normal operations up to ten thousand, so just need ten thousand above technical personnels, but wind-powered electricity generation enterprise is difficult to turn out at short notice so many young and healthy, the talent that technical merit is high comes, from generating one-tenth originally, more its costs of employment will be higher, therefore alleviate maintainer's labour intensity, make each technical personnel when wind-powered electricity generation unit is safeguarded, automatically rise tower, save their muscle power, could increase work efficiency by actv., reduce the cost of wind-powered electricity generation.
Except alleviating manpower consumption's needs, on the other hand, when wind-powered electricity generation unit need to be changed the larger parts of weight, dependence personnel are unpractical by parts back tower top, at this moment just need to upwards carry with the suspension hook that is located at blower fan body afterbody, and now the personnel on top will open the window of body afterbody, standing in window carries out operation, the danger coefficient of this work is very large, and personal safety accident very easily occurs.And because blower fan is installed in rapidly area of wind speed, instantaneous wind speed reaches 25m/s sometimes, be easy to lifting parts to blow out and horizon into about miter angle, cannot upwards transport smoothly testing tool and parts.In sum, develop a kind of ectocine that is not subject to, the manned loading automatic lifting of Elevator elevator has just become a very urgent problem.
In order to solve this problem, many companies and scientific research personnel have also carried out many explorations, develop some products, and what wherein Occupation coefficient was the highest is " climb-aiding device ".As its name suggests, " climb-aiding device " is exactly a kind of machine that helps people to climb, and in actual use, " climb-aiding device " maximum shortcoming is not make people be separated from climbing, and has following shortcoming: the one, and man-machine needs coordinates, and coordinates the bad personnel will be in passive; The 2nd, the slow efficiency of speed is low, and the climbing speed of " climb-aiding device " is constant, and control operation system is relatively single, cannot promote to greatest extent work efficiency; The 3rd, safety factor is low, in climbing, is provided with good cooperation once man-machine, and personnel just have dangerous possibility; The 4th, when mental fatigue appears in operating personnel, in climbing process, easily bump, cause personal safety accident, cause safety factor to reduce; The 5th, when blower fan need to be changed parts, need personnel's climbing of bearing a heavy burden; The 6th, cost is high, and with respect to simple function and the structure of " climb-aiding device ", the input-output ratio of the cost that it is relatively high is relatively low.
The patent of application number 201220246106.6 discloses in a kind of wind power generating set air duct with elevator, the fixed sturcture of guide rail bracket, driving system and guide rail bracket, consists of.Guide rail bracket is to be bolted and to be formed by a plurality of cuboid standard knots.Driving system is comprised of driver plate, retarder, electrical motor and car.The fixed sturcture of guide rail bracket is comprised of attached wall system and air duct wall.Guide rail bracket, along the air duct wall slant setting of air duct, is fixed by attached wall.One end connection guide rail frame of attached wall, the other end connects air duct wall.By motor driving reducer, rotate, by driver plate, drive car to move up and down along guide rail.Solve like this maintenance personnel, initial installation personnel utilization vertically walks the labour intensity that ladder climbs up and down, can also be for maintenance personnel and air duct installation personnel carrying implement and a small amount of material, and bont has the structures such as motor reducer to be assembled into, complex structure, installation footprint is large.
Given this utility model is proposed.
