Abstract
The invention relates to a lift type straight arm. The lift type straight arm comprises a fixed section mounted on a cross arm, and a telescopic section capable of going up and down along the fixed section is arranged on the fixed section. The lift type straight arm is characterized in that the single side of the fixed section is provided with a hydraulic cylinder, the piston rod of the hydraulic cylinder is connected with the telescopic section and can drive the telescopic section to go up and down along the fixed section; the upper end of the telescopic section is connected with the straight arm through a pivotal bearing, the telescopic section is connected with the outer ring of the pivotal bearing, and the straight arm is connected with the inner ring of the pivotal bearing. The outer ring of the pivotal bearing is provided with a first wheel gear, a rotation motor is mounted on the straight arm, the power output shaft of the rotation motor is provided with a second wheel gear, and the second wheel gear and the first wheel gear are engaged. Two ends of the straight arm are respectively provided with a first pulley wheel and a second pulley wheel. The lift type straight arm provided by the invention realizes free lifting by a single cylinder, and is hidden to the greatest extent.
Description
Technical field
The present invention 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 to 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 the most safe, practical, the efficient special equipment of work high above the ground.Because height, outward appearance, facade structures form, the roof bulk of building are not identical, must 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 objective of the invention is to overcome the deficiencies in the prior art, a kind of lift in-line arm is provided, can realize that in-line arm moves freely up and down in effective range, at utmost realize disguised.
According to technical scheme provided by the invention, described lift in-line arm, comprise the fixed knot that is installed on the transverse arm, arranging at 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 at 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 of the present invention 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 invention.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with concrete accompanying drawing.
Such 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 present invention includes the fixed knot 5 that is installed on the transverse arm 2, arranging at 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 at described in-line arm 1, the second gear 9, the second gears 9 and 7 engagements of the first gear 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 invention: in-line arm 1 of the present invention is in the drawing process of hydraulic cylinder 3, lift height 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.
