Abstract

The utility model discloses a novel rain brush on a pneumatic water-scraping device of a diesel locomotive, comprising a brush piece (1), a brush arm (2) and three master parts of a brush rack joint (3). The rain brush adopts the bridge-type brush piece, and the brush piece and the brush arm are connected together through the brush rack joint which is provided with top threads; when moving up and down along the brush arm, the brush piece is regulated; in addition, the rain brush and a shaft of the water-scraping device adopt clamping-type joint connection so that the rain brush is properly positioned along the circumferential direction with the shaft of the water-scraping device as a circle center.

Description

The novel rain brush of diesel locomotive new type pneumatic wiper

The utility model relates to a kind of rain brush part of diesel locomotive new type pneumatic wiper.

Existing locomotive Windshield Wiper rain brush, to scrape cleanliness not high, tangible scratch arranged, to scrape net area narrow.Development along with the internal combustion express locomotive, the locomotive head forms blast air and impacts, and the adhesive tape on the existing rain brush is thin, holds to can't stand the brush arm pressing force of the spring that is increased for the impact of opposing blast air, in the middle of work, cause adhesive tape moving, cisco unity malfunction in the rollback that comes up of glass face.In addition, existing rain brush, wiper position can not be adjusted, and inconvenient sometimes driver watches from a height or a distance.

The purpose of this utility model will provide a kind of can adapt to the development of modern ic locomotive, guarantees the windshield outwash device that trainman's sight line is clear, the visual field is spacious, clear, comfortable.

The purpose of this utility model is achieved in that the novel rain brush of this diesel locomotive new type pneumatic wiper comprises brush sheet, brush wall and three main parts of brush holder joint, brush sheet and brush arm are to link together by a brush holder joint of being furnished with jackscrew, the brush sheet can prolong brush arm and go here and there adjustment up and down, fix with jackscrew then, make it to adjust to suitable scraping position like this; And the brush sheet is made up of main bridge, secondary bridge, adhesive tape, and adhesive tape and two secondary bridgings connect, and the section of adhesive tape is a kind of ladder-type structure, and two secondary bridges connect by rivet and main bridging respectively; Brush arm is made up of extension arm, extension spring, spring hook and joint, one end of extension spring is fixed on the extension arm, the other end is connected on the clamped-in style joint by the spring hook, its clamped-in style joint left end is processed a groove, be used for being connected with the spring hook, right-hand member is processed a hole, in order to be connected with wiper shaft, have hex screw and half-round head screw on the clamped-in style joint, hex screw is used for captiveing joint of joint and wiper shaft.Because adopted bridge-type brush sheet, it can be evenly distributed in some thrusts on the brush arm on the whole adhesive tape, and adhesive tape and glass face can evenly be fitted closely, can improve outwash efficient, increases to scrape net area, and can adapt to convex concave glass face.In order to improve the impact resistance of rain brush, main bridge, secondary bridge, all corresponding intensity that increased of adhesive tape, rain brush adopts the clamped-in style joint to be connected with wiper shaft in addition, makes rain brush appropriate location on the circumferencial direction that with the wiper shaft is the center of circle.

The utility model has been owing to adopted bridge-type brush sheet, brush holder joint and clamped-in style joint etc. to realize scraping the cleanliness height, scraped big, the adjustable wiper of net area position, and the appearance design exquisiteness, flexibly, advantages such as dependable performance, long service life.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1, be the novel rain brush of diesel locomotive new type pneumatic wiper brush chip architecture scheme drawing;

Fig. 2, be the novel rain brush brush arm of diesel locomotive new type pneumatic wiper structural representation.

Describe concrete structure of the present utility model and service condition in detail below in conjunction with accompanying drawing: the novel rain brush of this diesel locomotive new type pneumatic wiper comprises brush sheet 1, brush arm 2 and 3 three main parts of brush holder joint, brush sheet 1 and brush arm 2 are to link together by a brush holder joint 3 of being furnished with jackscrew 5, brush sheet 1 can prolong brush arm 2 and go here and there moving adjustment up and down, fixing with jackscrew 5 then, and brush sheet 1 is made up of main bridge 6, secondary bridge 7, adhesive tape 8, adhesive tape 8 is connected with two secondary bridges 7, and two secondary bridges 7 are connected with main bridge 6 by rivet 4 respectively; Brush arm 2 is made up of extension arm 9, extension spring 10, spring hook 11 and clamped-in style joint 12, one end of extension spring 10 is fixed on the wall extension 9, the other end is connected on the clamped-in style joint 12 by the spring hook, its clamped-in style joint 12 left ends are processed a groove, be used for being connected with spring hook 11, right-hand member is processed a hole 15, in order to be connected with wiper shaft, has hexagonal-head screw 16 and half-round head screw 14 on clamped-in style joint 12.During use the clamped-in style joint 12 on the rain brush is fixed on the wiper shaft, and is adjusted to suitable position, will adjust the stationkeeping of brushing sheet 1 by jackscrew 5 simultaneously and get final product well.
