Abstract
The invention discloses a kind of novel pneumatic wiper, it is made up of power transmission shaft 3, support set 4, support 5, swing arm 6, slide block 7, cylinder 9, fairlead 8, piston rod 1, machine control valve 2 etc., piston rod 1 and slide block 7 are hinged, swing arm 6 is fixed on the input of power transmission shaft 3, the output of power transmission shaft 3 is connected with scraping brush assemblies, swing arm 6 promotes power transmission shaft 3 to move, it is achieved power exports, and makes wiper work.Compared with prior art, it provides the benefit that the present invention: frame for movement is simple, and property stable and reliable for performance is high, and the life-span convenient for installation and maintenance is long.
Description
Technical field
The present invention relates to a kind of vehicular traffic pneumatic wiper of particularly bullet train.
Background technology
At present, the wiper that each vehicular traffic uses, the gentle driving of electric drive two kinds can be divided into by its driving principle, electricity
Drive with its compact conformation, on the cheap wiper being widely used in various vehicular traffic, but, owing to motor is frequent
Rotating and the change of wiper resistance, make wiper motor Frequent Troubles, affects using effect and driving safety, particularly at height
Applying on speed locomotive, poor stability, reliability is low, and noise is big, it is impossible to meet express locomotive service requirement well, along with
Haulage vehicle speed improves, and this contradiction is more prominent, and then, people have developed a kind of pneumatic wiper, the most abroad
It is applied on express locomotive, and perfect by updating, shape, and along with express locomotive technology is introduced into together,
The air motor of this pneumatic wiper is mainly made up of two serial cylinders and one group of pinion and rack, and two pistons are consolidated
Being scheduled on piston rod two ends, the middle part of piston rod is provided with pinion and rack, one end of gear shaft and tooth bar engagement, the other end and scraping
Brush assemblies connects, and its operation principle is: piston promotes rack-and-pinion to move by piston rod, and gear shaft drives wiper swing and lead to
Cross corresponding air-path control system and realize wiper work, for increasing rigidity, tooth bar (or in the middle part of piston rod) back side, be provided with straight line
Bearing.The pinion and rack of this pneumatic wiper primary drive part is arranged in the middle of two cylinders, narrow space, its processing,
Installation requirement is tight, and manufacturing cost is high；Gear shaft supported at three point, belongs to redundant structure, and objective due to manufacturing and fixing error is deposited
, this structure easily causes two ends to support unbalance loading, causes eccentric wear between axle sleeve and gear shaft, thus causes gap between the gear teeth
Increasing, noise increases, and transmission efficiency declines；Meanwhile, piston eccentric wear, gear teeth unbalance loading are brought.So, gear teeth flow, fracture
And blow-by of piston is the principal mode that this wiper lost efficacy.And, this inefficacy is not easily repaired, working service cost
The highest, it is difficult to ensure that normally work in its life cycle management, impact is promoted the use of.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, dependable performance, easy for installation, environmental protection and energy saving, non-maintaining, low one-tenth
This pneumatic wiper.
The present invention solves its technical problem, and the technical scheme used is: existing product is analyzed research, takes long benefit
Short, and be operated with single air cylinder driven one swing arm replacement twin-tub pinion and rack, its design feature is: one with guiding
The variation cylinder of set is fixed on support, and the external part of piston bar is provided with a fairlead fixing with support, piston rod
The other end and slide block hinged, slide block can move freely along swing arm, and swing arm and rotary shaft connect, and power transmission shaft drives and scrapes brush assemblies
Being operated, whole device for mechanical simple in construction, property stable and reliable for performance is high, and the life-span convenient for installation and maintenance is long.
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the general structure schematic diagram of the embodiment of the present invention.
Detailed description of the invention
Embodiment one
Fig. 1 illustrates, a kind of detailed description of the invention of the present invention is: a kind of novel pneumatic wiper, containing cylinder 9, piston rod 1,
Fairlead 8, swing arm 6, support 5, slide block 7, support set 4, power transmission shaft 3, machine control valve 2 etc. form, and its design feature is:
Support set 4 is fixed on support 5 with cylinder 9 and is mutually perpendicular to, and power transmission shaft 3 is fixed on support set 4, and can be around propping up
Support set 4 rotates, and the output of power transmission shaft 3 is connected with scraping arm component by spline, and input and the swing arm 6 of power transmission shaft 3 are fixed,
Kink one slide block 7 in swing arm 6, slide block 7 promotes swing arm 6 to slide up and down and rotates around power transmission shaft 3 with swing arm 6, piston rod 1
Being hinged on slide block 7 through fairlead 8, compressed air promotes piston to pass to slide block 7, and warp through 1 power of piston rod
Power transmission shaft 3 drives scraping arm to work, and the commutation of scraping arm both can be completed by the air-path control system of machine control valve 2, it is possible to passes through cylinder
Internal reversing shaft of putting completes.
Embodiment two
In Fig. 1 illustrates wiper into, swing arm 6 is changed gear, and fix a toothed rack at the external part of piston rod 1, remaining structure
Constant, the function of wiper equally can realize.
