Along with the development of present social science and technology, the necessity that surface of high building is installed window cleaning equipment has obtained generally approval, and window cleaning equipment is that work high above the ground is the most safe, practical, efficient special equipment.Because height, outward appearance, facade structures form, the roof bulk of building are not identical, must be by the people on platform (as hanging ship) with the window cleaning equipment arm near different facades, and directly to the curtain wall facade clean, the operation such as maintenance.Hang a lot of occasions of stage apparatus and all can use the dovetail arm, window cleaning equipment is in when knocking off state, needs to consider disguise, requires the dovetail arm to be upturned 44.4 °, then is down to 4.4 °, and wherein the most basic requirement is namely that two suspension centres distances will keep 2 meters all the time.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of formula dovetail arm of bowing of facing upward is provided, and can realize the pitching action of dovetail arm, and remains that the distance between two suspension centres of dovetail arm end is certain.
The technical scheme that provides according to the utility model, the described formula dovetail arm of bowing of facing upward comprises mount pad, it is characterized in that: described mount pad top is connected with dovetail arm supporting base by pivoting support, the inner ring of mount pad and pivoting support is fixed, and the outer ring of dovetail arm supporting base and pivoting support is fixed; Connect the first dovetail arm and the second dovetail arm by bearing pin respectively on described dovetail arm supporting base, the first dovetail arm and the second dovetail arm are done respectively elevating movement centered by bearing pin; The first cylinder mounting bracket and the second cylinder mounting bracket are set on described dovetail arm supporting base, the first cylinder mounting bracket and the second cylinder mounting bracket are rotationally connected with the cylinder body of the first cylinder and the second cylinder respectively, the piston rod of the first cylinder and the first dovetail arm are rotationally connected, and the piston rod of the second cylinder and the second dovetail arm are rotationally connected.
The first gear is set on the outer ring of described pivoting support, on described mount pad, reducing motor is installed, the clutch end of reducing motor arranges the second gear, the second gear and the engagement of the first gear.
Be the acute angle setting between described the first dovetail arm and the second dovetail arm.
Be provided for respectively installing the first roller mount and second roller mount of roller in the end of described the first dovetail arm and the second dovetail arm.
The formula dovetail arm of bowing of facing upward described in the utility model can be in the state of steeving in when work, and the two suspension centres ship of slinging has been crossed parapet and carried out cleaning, the maintenance work of wall face; When knocking off, will hang ship and intrude in parapet, window cleaning equipment is moved to the rest area by walking mechanism, the dovetail arm draws in, reaches hidden effect.

Fig. 2 is the top view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As Fig. 1～shown in Figure 3: as described in face upward the formula dovetail arm of bowing and comprise mount pad 1, the first dovetail arm 2-1, the second dovetail arm 2-2, pivoting support 3, reducing motor 4, the first cylinder 5-1, the second cylinder 5-2, the first roller mount 6-1, the second roller mount 6-2, dovetail arm supporting base 7, the first gear 8, the second gear 9, the first cylinder mounting bracket 10-1, the second cylinder mounting bracket 10-2 etc.
As Fig. 1, shown in Figure 3, the utility model comprises mount pad 1, and mount pad 1 top is connected with dovetail arm supporting base 7 by pivoting support 3, and the inner ring of mount pad 1 and pivoting support 3 is fixed, dovetail arm supporting base 7 is fixed with the outer ring of pivoting support 3, and the first gear 8 is set on the outer ring of pivoting support 3; Reducing motor 4 is installed on described mount pad 1, and the clutch end of reducing motor 4 arranges the second gear 9, the second gears 9 and the first gear 8 engagements;
As shown in Figure 1 and Figure 2, be rotationally connected the first dovetail arm 2-1 and the second dovetail arm 2-2 by bearing pin respectively on described dovetail arm supporting base 7, the first dovetail arm 2-1 and the second dovetail arm 2-2 are the angle setting of 44.4 °, the first dovetail arm 2-1 and the second dovetail arm 2-2 do respectively elevating movement centered by bearing pin, be provided for respectively installing the first roller mount 6-1 and the second roller mount 6-2 of roller in the end of the first dovetail arm 2-1 and the second dovetail arm 2-2;
