Intelligent safety overhaul ladder stand for wind driven generator

Technical Field

The utility model belongs to the technical field of aerogenerator overhauls utensil technique and specifically relates to an aerogenerator intelligent security overhauls cat ladder.

Background

With the continuous consumption of non-renewable energy and the continuous popularization of the sustainable development of the environment, besides conventional coal thermal power generation, wind power generation using green energy is also continuously developed, and a wind power generator is power equipment which converts wind energy into mechanical power, the mechanical power drives a rotor to rotate, and finally outputs alternating current, and generally comprises components such as a wind wheel, a generator, a direction regulator, a tower, a speed-limiting safety mechanism, an energy storage device and the like. In order to obtain sufficient wind energy, the impeller is arranged at a higher position, the height of the tower is very high, the stability of the whole wind driven generator is guaranteed, the tower is generally a small-end large round platform type structure, the internal overhauling crawling ladder is mostly fixed on the inner wall in an inclined state, once an overhauling person takes off his hands in the climbing process, the overhauling person can hang at the position of the center shaft of the tower under the protection of a safety rope and only can wait for rescue, the self-rescue is difficult to implement, and the crawling ladder is difficult to return to, so that unnecessary trouble is brought to the overhauling of the wind driven generator.

Disclosure of Invention

In order to solve the problem, the utility model aims to provide a aerogenerator intelligent security overhauls cat ladder can be when the maintainer falls from the cat ladder carelessly, and the implementation is saved oneself and is got back to and continue to overhaul on the cat ladder.

The utility model provides a technical scheme that its technical problem adopted is: an aerogenerator intelligent security overhauls cat ladder, including first ladder frame and second ladder frame, first ladder frame and second ladder frame are all fixed on the aerogenerator tower inner wall of slope fixed mounting has the stull that is used for the climbing between first ladder frame and the second ladder frame, is equipped with the spout along its length direction on the lateral surface of first ladder frame, and the slider is installed to the spout fit in set up rectangular hole on the lateral surface of spout, the soft rope of fixed connection on the slider, the spout is worn out via rectangular hole to the soft rope, the one end fixed connection slider of soft rope, the other end of soft rope is equipped with elastic glove. Further, all install pressure sensor on the three stull of cat ladder bottom, corresponding to every pressure sensor's position, be equipped with three proximity switch in proper order on first ladder frame, the controller is installed to the bottom position department of second ladder frame, in above-mentioned pressure sensor and proximity switch all had wire access controller still be equipped with the warning light on the controller, when pressure sensor is in operating condition and proximity switch can not detect the slider and remove, the warning light circular telegram sends the police dispatch newspaper. Furthermore, the slide block is a T-shaped slide block matched with the sliding groove and the long hole.

The utility model has the advantages of: an aerogenerator intelligent security overhauls cat ladder, be equipped with in one side of first ladder frame and follow the connecting device that the maintainer removed together, drive the slider through the maintainer hand strap elasticity gloves via the soft rope and reciprocate, even the maintainer falls the cat ladder, lie in pylon central axis position under the protection of safe rope, also can implement to save oneself through the pulling soft rope and get back to on the cat ladder. The proximity switches near pressure sensor on the bottom stull and stull work of mutually supporting can remind the maintainer to wear the operation of overhauing again after elastic gloves under the suggestion of warning light, also can avoid falling from the cat ladder and take place the unable condition of saving oneself, fully guarantees maintainer's safety work.

In the figure, 1, a first ladder frame 2, a second ladder frame 3, a cross brace 4, a sliding chute 5, a sliding block 6, a long hole 7, a soft rope 8, an elastic glove 9, a pressure sensor 10, a proximity switch 11 and a controller 12 are arranged on the alarm lamp.

Detailed Description

A aerogenerator intelligent security overhauls cat ladder, as shown in figure 1 and figure 2, including first ladder frame 1 and second ladder frame 2, first ladder frame 1 and second ladder frame are all fixed on the wind power generation tower inner wall of slope fixed mounting has the stull 3 that is used for the climbing between first ladder frame 1 and the second ladder frame 2, is equipped with spout 4 along its length direction on first ladder frame 1's the lateral surface, as shown in figure 3, slider 5 is installed to spout 4 fit in set up rectangular hole 6 on spout 4's the lateral surface, fixed connection soft rope 7 on the slider 5, spout 4 is worn out via rectangular hole 6 to soft rope 7, the one end fixed connection slider 5 of soft rope 7, the other end of soft rope 7 is equipped with elastic glove 8.

When the maintainer gets into the pylon, before climbing the cat ladder and overhauing, at first tie the safety rope, the safety rope is fixed in the central point department at pylon top, later need take elastic glove 8, climb the cat ladder again and overhaul aerogenerator inside, along with the up-and-down movement of maintainer on the cat ladder, elastic glove 8 can drive slider 5 via soft rope 7 and remove in spout 4, even the maintainer falls from the cat ladder, hang the center pin position department at the pylon by the safety rope, no matter how big the inside distance of aerogenerator pylon has, still there is soft rope 7 to link to each other between maintainer and the cat ladder, pulling soft rope 7 just can realize saving oneself and get back to on the cat ladder, need not the original place and wait for the rescue, the maintenance efficiency to whole aerogenerator has been accelerated.

Further, in order to make the maintainer take elastic gloves 8 before climbing the cat ladder, guarantee that the maintainer is in connected state with cat ladder upper slide 5, avoid can't realizing saving oneself because of falling the cat ladder, as shown in fig. 2, all install pressure sensor 9 on the three stull 3 of cat ladder bottom, corresponding to the position of every pressure sensor 9, be equipped with three proximity switch 10 on first ladder frame 1 in proper order, controller 11 is installed to the bottom position department of second ladder frame 2, is equipped with control circuit board and power in the controller 11, above-mentioned pressure sensor 9 and proximity switch 10 all have wire access controller 11 in still be equipped with warning light 12 on the controller 11, when pressure sensor 9 is in operating condition and proximity switch can't detect the slider 5 removal, warning light 12 circular telegram sends the police dispatch newspaper. If the maintainer does not wear elastic gloves 8 before climbing the cat ladder, then slider 5 can not follow the maintainer and remove, and when the maintainer began to climb up the stull 3 of bottom, pressure sensor 9 was in operating condition, but slider 5 did not produce the removal and did not trigger proximity switch 10, at this moment at controller 11 control warning light 12 circular telegram and send out the police dispatch newspaper, reminds the maintainer to wear again to climb the ladder after elastic gloves 8 and overhauls.

Further, in order to enable the sliding block 5 to be installed in the sliding groove 4 in a more stable and matched manner, as shown in fig. 4, the sliding block 5 is a T-shaped sliding block matched with the sliding groove 4 and the strip hole 6, so that the soft rope 7 is fixed on the sliding block 5 protruding out of the sliding groove 4, friction between the soft rope and the strip hole 6 is avoided, and the service life of the soft rope is prolonged to a certain extent.

Technical scheme of the utility model not be restricted to the utility model the within range of embodiment. The technical contents not described in detail in the present invention are all known techniques.
