Abstract

The utility model discloses a double rotary single arm cleaning machine, comprising a brush roll, a brush arm, an upright post, and two electric machines. The brush roll is hung on the front end of the brush arm via a shaft coupling, and the shaft coupling is positioned inside a belt pulley. The brush arm is connected with the upright post via a rotating shaft assembly, and the brush arm is provided with the motor, a weight punch, a weight punch positioning system, and the retracting mechanism of the brush arm. The weight punch system uses flexible ropes to connect with the brush arm and be hung inside the upright post. The retracting mechanism of the brush arm is engaged with the toothed disk of the upright post and is driven by a rotary electric machine. A main electric machine drives the brush roll to rotate via a belt drive system. The cleaning machine adopts the flexible connection mode and has the advantages of good effect, strong adaptive ability, etc.

Description

Double rotary single arm cleaning machine

The utility model relates to vehicle cleaning machinery, especially the automobile-use scrubbing unit.

Existing automobile-use scrubbing unit mainly contains two classes: a class is the framed structure that is fit to certain specific vehicle, the scrubbing unit complex structure of this class formation, bad adaptability; Another kind of is that up and down two pivoted arms support the structure of brush rolls, and it is to be solved that the scrubbing unit of this class formation exists following shortcoming to have:

1, because the brush roll two ends for being rigidly connected, do not have adaptivity to body contour, and washing effect is poor, and the brush line is easy to collude trailer body annex (as rain brush, side mirror etc.).

2, brush arm adopts the rigidity locating part, is easy to cause clashing and breaking vehicle body phenomenon.

3, do not set up brush arm to regain system, can't directly regain brush roll for the vehicle that on washing track, is not suitable for vehicle body is scrubbed and let pass.

The purpose of this utility model provides a kind of bispin single armed scrubbing unit, the scrubbing of the different body contours of this function self adaptation, and washing effect is good, and can not damage vehicle body and collude trailer body annex.Simultaneously, brush arm is recoverable.

The purpose of this utility model is achieved in that it is made of brush roll, brush arm, column and motor, and brush roll is suspended on the front end of brush arm by coupler, and brush arm links to each other with column by rotating shaft assembly, and motor is contained on the brush arm.Coupler is positioned at the inside of belt pulley, and the transmission center of its mounting center and belt pulley has certain altitude poor, also is provided with weight position fixing system and brush arm retraction mechanism on the brush arm.The weight position fixing system links to each other with brush arm with flexible strand, overhangs in the column.Fluted disc engagement on retraction mechanism and the column.

Accompanying drawing is structural representation of the present utility model.

Below in conjunction with accompanying drawing, structure of the present utility model and principle of work are described in detail.

As shown in the figure, brush arm 3 connects with column 8 by rotating shaft assembly 4, and by the weight position fixing system brush arm 3 is positioned at reference position, and when brush roll 1 that the vehicle promotion is being rotated, brush arm 3 can be around rotating shaft assembly 4 rotations, to adapt to different overall width.

Main motor 7, turning motor 6, brush arm retraction mechanism 5, reductor 11, drive pulley 10 and coupler 2 are housed on the brush arm 3.Main motor 7 drives brush roll 1 rotation by drive pulley 10 by belt drive system after reductor 11 slows down.Coupler 2 is contained in drive pulley 10 inside and links to each other with brush arm 3, and brush roll 1 hangs on the brush arm, because the effect of coupler 2, brush roll 1 can freely tilt in certain angular range, to adapt to different contour of the vehicles.There is a diff-H at the transmission center of the mounting center of coupler 2 and drive pulley 10, and this difference has guaranteed brush roll 1 stall (slipping of the belt) automatically when overload, thereby plays the effect of protection vehicle.

The weight position fixing system is made up of weight 9, pulley 12, connecting lever 14, guard rail 13 and flexible strand 15.Flexible strand one end is fixed on the brush arm 3, the other end links to each other with weight 9 by guard rail 13, pulley 12, weight 9 hangs in the column, the reference position of brush arm 3 has been determined in the position of connecting lever 14, and when rotate the stressed back of brush arm, weight will rise, brush arm is subjected to the rotating trend power of initial bit, after external force is removed, brush arm will automatically rotate back into initial position, and flexible strand selects for use steel rope or nylon rope all can.Turning motor 6 can be received brush arm to off-position when needed by the engagement of the fluted disc on belt drive brush arm retraction mechanism 5 and the column 8.

The utility model compared with prior art has following outstanding advantages:

1, the balanced type brush arm can be around the revolution of column central shaft, and brush roll adapts to different model vehicle overall width automatically; The weight Chong Li Heng that dangles in the column is fixed, so that brush roll is fixed to the Ya Jin Li Heng of vehicle body, and brush arm two ends equalising torque, the vehicle motive force is little.

2, single-arm suspension brush roll, brush roll is connected with coupler with brush arm, and by belt direct drive brush roll, formation flexibly connects system, brush roll can be brushed line and be difficult for being stuck in the bodywork gap according to vehicle needs wing drop one angle in the process of scrubbing, do not twine body accessory.

3, coupler is installed in drive pulley inside, and makes its center of turn and belt center keep a segment distance, reaches the brush roll auto-centering, the automatic protection functions of stability of rotation and overload automatic stop (slipping of the belt).

4, brush arm adopts weight lowest potential energy location, does not have the rigidity locating part, has eliminated because the problem of the clashing and breaking vehicle body of machinery.

5, independently brush arm retraction mechanism is arranged, can directly regain brush roll and let pass on washing track, being not suitable for carrying out vehicle that vehicle body scrubs.
