Specific embodiment
With reference to figure 1- Fig. 4, the problem of for security risk existing for hand sweeping glass curtain wall and long period, the present invention carries
For a kind of cleaning equipment of glass curtain wall, including frame 1, clearing apparatus 2 and telecontrol equipment 3, clearing apparatus 2 includes principal axis A 4
With the hairbrush 5 being arranged in principal axis A 4, principal axis A 4 is arranged on frame 1, and motor A6, the output of motor A6 are provided on frame 1
Belt wheel A7 is provided on axis, belt wheel B8 is provided in principal axis A 4, synchronous belt A9 is provided between belt wheel A7 and belt wheel B8；
Frame 1 is square structure, is provided with main shaft B10 on frame 1,1 corner location of frame is provided with telecontrol equipment 3, sportswear
It puts 3 and includes eccentric wheel 11, toggle 12 and supporting leg 13, eccentric wheel 11 is connect with toggle 12, supporting leg 13
It is connect with toggle 12.
Supporting leg 13 includes supporting rod 14 and sucker 15, and 14 one end of supporting rod is connect with toggle 12, and the other end is set
It is equipped with sucker 15.
Toggle 12 is arranged on 1 outside of frame by support shaft 16, and support shaft 16 is arranged on the horizontal stroke of 1 both sides of frame
17 outside of beam.
Band plummer block housing bearing A18, main shaft B10 are provided on 1 both sides crossbeam 17 of frame and is arranged on band plummer block housing bearing A18
On.
Eccentric wheel 11 is arranged on the both ends of the main shaft B10 in 1 outside of frame.
Band plummer block housing bearing B19 is provided on 1 both sides crossbeam 17 of frame, principal axis A 4 is arranged in band plummer block housing bearing B19.
Hairbrush 5 includes axle sleeve 20, and 20 outside of axle sleeve is provided with soft continuous body nylon cotton silk thread 21, and axle sleeve 20 is socketed in principal axis A 4
On.
Principal axis A 4 is at least two, and synchronous belt B22 is provided between principal axis A 4.
Main shaft B10 is at least two, and synchronous belt C23 is provided between main shaft B10.
Motor B24 is provided on frame 1, the output shaft of the motor B24 is connected with the main shaft B10 by synchronous belt D25
It connects.
Telecontrol equipment and clearing apparatus are arranged in two different drive systems by the present invention, and the purpose designed in this way has
Two, first, telecontrol equipment is at " across foot " or adsorbs when on metope, cleaning equipment is all had been in motion state；
Second is when there is set of system to be damaged, and can individually be repaired with regard to this system, easily disassembled.
Soft continuous body nylon cotton silk thread is fixedly connected in clearing apparatus on the outside of sleeve, software nylon cotton thread is not easy to scratch
Sleeve is fixed on main shaft by glass surface, realizes the linkage form that turnover hairbrush turns, and the purpose of two hairbrush of design is,
One hairbrush carries out coarse scan, such as fallen leaves, birds droppings etc. to the dietary fibres on glass curtain wall surface, another hairbrush is to glass curtain wall
Surface wash sweeping, and coarse scan and washes to sweep and is carried out at the same time, and can improve working efficiency, be that motor driving spindle has been used to transport in this scheme
