Abstract

The utility model relates to a lifting type straight line-shaped arm. The lifting type straight line-shaped arm comprises a fixed joint mounted on a cross arm, wherein a telescopic joint capable of lifting along the fixed joint is arranged on the fixed joint; the lifting type straight line-shaped arm is characterized in that a hydraulic cylinder is mounted on one side of the fixed joint; a piston rod of the hydraulic cylinder is connected with the telescopic joint and can drive the telescopic joint to lift along the fixed joint; the upper end of the telescopic joint is connected with a straight line-shaped arm through a rotating bearing; the telescopic joint is connected with the outer ring of the rotating bearing; and the straight line-shaped arm is connected with the inner ring of the rotating bearing. A first gear is arranged on the outer ring of the rotating bearing; a rotating motor is mounted on the straight line-shaped arm; a second gear is arranged on a power output shaft of the rotating motor; and the second gear is engaged with the first gear. A first pulley and a second pulley are respectively arranged at the two ends of the straight line-shaped arm. The lifting type straight line-shaped arm provided by the utility model has the advantage as follows: as the straight line-shaped arm is freely lifted through adoption of single cylinder, concealed property is furthest achieved.

Description

The lift in-line arm

Technical field

The utility model relates to a kind of skyscraper implement, especially a kind of lift in-line arm.

Background technology

Along with the increasing high level of China and high-rise building stand from the city, attractive in appearance for the light transmission that increases interior of building and exterior wall, modern high-rise outer wall top-grade building is often selected glass curtain wall structure, keep the neat and artistic for a long time of external wall outward appearance, just need the External Wall building regularly clean and safeguard.This just has been doomed high-rise service equipment---window cleaning equipment popularization and application at home.

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, and a lot of occasions of device of hanging platform are all used in-line arm.Window cleaning equipment is in when knocking off state, needs to consider disguise, requires in-line arm to descend lowlyer as far as possible.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of lift in-line arm is provided, and can realize that in-line arm moves freely in effective range up and down, at utmost realizes disguised.

The technical scheme that provides according to the utility model, described lift in-line arm, comprise the fixed knot that is arranged on transverse arm, arranging on fixed knot can be along the telescopic joint of fixed knot lifting, it is characterized in that: at the one-sided installation hydraulic cylinder of described fixed knot, the piston rod of hydraulic cylinder is connected with telescopic joint, can drive telescopic joint along the fixed knot lifting; The upper end of described telescopic joint is connected with in-line arm by floating bearing, and telescopic joint is connected with the outer ring of floating bearing, and in-line arm is connected with the inner ring of floating bearing.

In the outer ring of described floating bearing, the first gear is set, installs back rotating motor on described in-line arm, the second gear is set on the power output shaft of turning motor, the second gear and the engagement of the first gear.

At the two ends of described in-line arm, the first pulley and the second pulley are set respectively.

Lift in-line arm described in the utility model adopts single cylinder to realize the in-line arm lifting freely, has farthest realized disguise.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the right view of Fig. 1.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete accompanying drawing.

As Fig. 1～shown in Figure 2: as described in the lift in-line arm comprise in-line arm 1, transverse arm 2, hydraulic cylinder 3, telescopic joint 4, fixed knot 5, floating bearing 6, the first gear 7, turning motor 8, the second gear 9, the first pulley 10, the second pulley 11 etc.

As shown in Figure 1 and Figure 2, the utility model comprises the fixed knot 5 that is arranged on transverse arm 2, and arranging on fixed knot 5 can be along the telescopic joint 4 of fixed knot 5 liftings, at the one-sided installation hydraulic cylinder 3 of fixed knot 5, the piston rod of hydraulic cylinder 3 is connected with telescopic joint 4, can drive telescopic joint 4 along fixed knot 5 liftings; The upper end of described telescopic joint 4 is connected with in-line arm 1 by floating bearing 6, and telescopic joint 4 is connected with the outer ring of floating bearing 6, and in-line arm 1 is connected with the inner ring of floating bearing 6, and the first gear 7 is set in the outer ring of floating bearing 6; Install back rotating motor 8 on described in-line arm 1, the second gear 9, the second gears 9 and the first gear 7 engagements are set on the power output shaft of turning motor 8;

As shown in Figure 1, at the two ends of described in-line arm 1, winding steel wire rope on the first pulley 10 and the second pulley 11, the first pulleys 10 and the second pulley 11 is set respectively, is used for hanging to establish hanging ship.

Operation principle of the present utility model: in-line arm 1 described in the utility model is in the drawing process of hydraulic cylinder 3, lift high by telescopic joint 4 and fixed knot 5, in-line arm 1 is in when lifting high state, first pulley 10 at two ends and the second pulley 11 have been crossed parapet and have been carried out cleaning, the maintenance work of wall face as the suspension centre ship of slinging; Hydraulic cylinder 3 shrinks conversely, and in-line arm 1 shrinks by telescopic joint 4 and fixed knot 5 in-line arm 1 is descended, and plays sequestration.
