Description
Technical field
The utility model relates to Portable wind electric brake technical field, particularly relates to the portable sealed property pick-up unit of a kind of wind power brake.
Background technology
After aerogenerator long-play, wind power brake just there will be leakage of oil in various degree, the mainly outside connected pipes of wind power brake, joint and inner sealing problem thereof can cause wind power brake leakage of oil, especially the bad leakage of oil caused of its inner sealing (particularly off-course brake), because oil inlet pipe and oil discharge pipe are connected in series, and detent and brake flange relatively rotate, as long as wherein a set of detent leakage of oil is on brake flange, in During yaw, fluid on brake flange can be taken to the position of other detent, cause often overlapping brake surfaces and have oil droplet, so be difficult to accurately judge to be which cover detent leakage of oil.At present, generally adopt Hydraulic Station (hydraulic pressure) or air lift pump or gas cylinder to detect the sealing of wind power brake, but there is certain viscosity due to hydraulic oil, cause the reflection leakage of oil time long, and judge inaccurate.If with air lift pump or gas cylinder, because volume is large, Heavy Weight, is not easy to carry.
Utility model content
The utility model mainly solves technical matters existing in prior art, thus provides a kind of sealing property that can detect product rapidly and accurately, and the portable sealed property pick-up unit of the simple and convenient wind power brake carried of structure.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
The portable sealed property pick-up unit of the wind power brake that the utility model provides, it comprises the aerator, retaining valve, the pressure-detecting device that are connected successively by flexible pipe, described pressure-detecting device is also connected with wind power brake, wherein, described aerator is used for providing pressure gas source, and described pressure-detecting device is for detecting the force value of wind power brake.
Further, also comprise a plug and a reversing arrangement, described plug is connected with one end of described pressure-detecting device is detachable, and for shutoff sealing pick-up unit, described reversing arrangement is arranged between described retaining valve and pressure-detecting device, and for the pressure release of wind power brake.
Further, described flexible pipe is threaded with aerator, retaining valve, pressure-detecting device, plug and reversing arrangement respectively, and its screw thread also scribbles fluid sealant.
Further, described flexible pipe and aerator, retaining valve, pressure-detecting device, also O-ring seal respectively between plug and reversing arrangement.
Further, described flexible pipe is high-pressure hose, and it is withstand voltage is greater than 5MPa.
Further, described aerator is manual or foot-operated inflating pump.
The beneficial effects of the utility model are: provide pressure gas source by aerator, pressure gas source enters in wind power brake through pressure-detecting device, pressurize a period of time, after voltage stabilizing, whether the force value detected by observing pressure-detecting device declines, the sealing property that judge the sealing of wind power brake, its structure is simple, easy to operate, product can be detected rapidly and accurately, and effectively improve work efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of wind power brake of the present utility model with portable sealed property pick-up unit.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1, the portable sealed property pick-up unit of wind power brake of the present utility model, it comprises the aerator 2, retaining valve 3, the pressure-detecting device 4 that are connected successively by flexible pipe 1, pressure-detecting device 4 is also connected with wind power brake, wherein, aerator 2 is for providing pressure gas source, and for the ease of carrying, aerator 2 is manual or foot-operated inflating pump.And pressure-detecting device 4 is for detecting the force value of wind power brake, in order to not damage the security of tensimeter and raising operating personnel, pressure-detecting device 4 is preferably the tensimeter of (1-1.6) MPa range.This device also comprises plug 5 and a reversing arrangement 6, plug 5 is connected with one end of pressure-detecting device 4 is detachable, and for shutoff sealing pick-up unit, the sealing of plug 5 mainly for detection of portable sealed property pick-up unit self is set, reduce the error measured, when measuring wind power brake product, need to pull down plug 5.Reversing arrangement 6 is arranged between retaining valve 3 and pressure-detecting device 4, and for the pressure release of wind power brake, wherein, reversing arrangement 6 is preferably the reversal valve of two-bit triplet.The safety of reversing arrangement 6 mainly for operating personnel is set, at the end of detection wind power brake product hermeticity, carries out first release and dismantle again.
Concrete, flexible pipe 1 is threaded with aerator 2, retaining valve 3, pressure-detecting device 4, plug 5 and reversing arrangement 6 respectively, and its screw thread also scribbles fluid sealant, is convenient to enhanced leaktightness performance.Further, in order to strengthen sealing property further, flexible pipe 1 and aerator 2, retaining valve 3, pressure-detecting device 4, also O-ring seal respectively between plug 5 and reversing arrangement 6.Preferably, in order to consider the life safety of maintainer, flexible pipe 1 is high-pressure hose, and it is withstand voltage is greater than 5MPa.
