Abstract
The invention relates to a high-altitude-vehicle ultralong telescopic arm system, which comprises a first telescopic section, a second telescopic section and a third telescopic section. The second telescopic section is mounted in the first telescopic section and in sliding fit with the first telescopic section, and the third telescopic section is mounted in the second telescopic section and in sliding fit with the second telescopic section. The system is characterized by arranging a telescopic driving oil cylinder between the first and the second telescopic section, and arranging a wire rope driving mechanism between the second and the third telescopic section. The wire rope driving mechanism drives the third telescopic section to stretch out or retract, and can tightly attach to the second telescopic section, without affecting the arrangement of the telescopic driving oil cylinder between the first and the second telescopic section, to enable the telescopic arm to fully retract. The inventive system is simple in structure.
Description
Technical field
The present invention relates to a kind of high empty wagons, design a kind of high empty wagons overlength telescopic boom system especially.
Background technology
High empty wagons is meant more than 3 meters, by hydraulic pressure or many hydraulic rams of power driven system domination, and lifting a kind of vehicle of carrying out operation up and down.It is widely used in aloft work fields such as electric power, street lamp, municipal administration, gardens, communication, airport, shipbuilding, traffic, advertisement, photography.
The high-altitude car owner will comprise the chassis, is located at the rotation platform on the chassis, and telescopic boom is installed on the rotation platform, the end erection work platform of telescopic boom.During work, telescopic boom can change extension elongation, thereby the position that changes workplatform adapts to different demands.At present traditional high empty wagons telescopic boom adopts two sections stretching structures, and it comprises telescopic section I, telescopic section II, and the telescopic section I is a canned paragraph; Be installed on the rotation platform; The telescopic section II is an active segment, and it is installed in the telescopic section I, the form that it is stretched out or withdraw through the stroke oil cylinder again.Three sections stretching structures are identical with two sections, increase the telescopic section III that embeds in the telescopic section II, and corresponding stroke oil cylinder.The syllogic telescopic boom has bigger operating radius, but structure is complicated, productive costs is higher, and owing to all adopt the relation of oil cylinder, does not have enough spaces to hold telescopic boom and withdraw fully, uses to receive certain limitation.
Summary of the invention
The technical matters that the present invention will solve provides a kind of simple in structure, applied widely high empty wagons overlength telescopic boom system.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of high empty wagons overlength telescopic boom system; Comprise telescopic section I, telescopic section II and telescopic section III, the telescopic section II with its bearing fit is housed in the said telescopic section I, the telescopic section III with its bearing fit is housed in the said telescopic section II; Its innovative point is: between said telescopic section I and the telescopic section II telescopic drive oil cylinder is set, between said telescopic section II and the telescopic section III steel rope driver train is set.
Further, said steel rope driver train comprises steel rope, front wheel, back pulley, and said forward and backward pulley is installed in the front and back ends madial wall of telescopic section II respectively; One end of said steel rope and telescopic section I be terminal to be connected fixingly, and the other end passes successively behind front wheel and the back pulley to be connected with telescopic section I front end and fixes, and front wheel is connected with the telescopic section III with length of cable between the back pulley and fixes.
The invention has the advantages that: between telescopic section II and the telescopic section III steel rope driver train is set, stretching out and shrinking by steel rope drive mechanism telescopic section III; The steel rope driver train can be close to the telescopic section II, does not influence the setting of telescopic drive oil cylinder between telescopic section I and the telescopic section II, guarantees that telescopic boom can withdraw fully, and use and receive certain limitation, and simple in structure.
Description of drawings
Fig. 1 is the high empty wagons overlength of a present invention telescopic boom system front view.
Fig. 2 is the high empty wagons overlength of a present invention telescopic boom system birds-eye view.
Fig. 3 is a partial enlarged drawing I among Fig. 2.
The specific embodiment
Like Fig. 1,2, shown in 3; Telescopic boom is a three stage structure; Comprise telescopic section I 1, telescopic section II 2 and telescopic section III 3, telescopic section I 1 is the rectangular sleeve tubular construction, and telescopic section II 2 is housed in it; Telescopic section II 2 and telescopic section I 1 bearing fit make telescopic section II 2 to move along the bearing of trend of telescopic section I 1 and realize stretching out or withdrawing.Telescopic section III 3 is housed in telescopic section II 2, and telescopic section III 3 and telescopic section II 2 bearing fits make telescopic section III 3 to move along the bearing of trend of telescopic section II 2 and realize stretching out or withdrawing.
Between telescopic section I 1 and the telescopic section II 2 the telescopic drive oil cylinder is set, the rear end of telescopic drive oil cylinder is fixed on telescopic section I 1 back segment, and the front end of telescopic drive oil cylinder is fixed on telescopic section II 2 back segments.
Between telescopic section II 2 and the telescopic section III 3 the steel rope driver train is set.Have a pair ofly in the present embodiment, this steel rope driver train comprises steel rope 4, front wheel 5, back pulley 6, and front wheel 5, back pulley 6 are installed in the front and back ends madial wall of telescopic section II 2 respectively.
One end of steel rope 4 and telescopic section I 1 be terminal to be connected fixingly, and the other end passes front wheel 5 successively and is connected with telescopic section I 1 front end with back pulley 6 backs and fixes, and front wheel 5 is connected with telescopic section III 3 with length of cable between the back pulley 6 and fixes.
Principle of work: stretch out and when regaining by telescopic drive hydraulic oil cylinder driving telescopic section II 2, and stretching out and shrinking by steel rope drive mechanism telescopic section III 3; The steel rope driver train can be close to telescopic section II 2, does not influence the setting of telescopic drive oil cylinder between telescopic section I 1 and the telescopic section II 2, guarantees that telescopic boom can withdraw fully.
Claims (2)
1. one kind high empty wagons overlength telescopic boom system; Comprise telescopic section I, telescopic section II and telescopic section III; Telescopic section II with its bearing fit is housed in the said telescopic section I; Telescopic section III with its bearing fit is housed in the said telescopic section II, it is characterized in that: between said telescopic section I and the telescopic section II telescopic drive oil cylinder is set, between said telescopic section II and the telescopic section III steel rope driver train is set.
2. high empty wagons overlength telescopic boom according to claim 1 system, it is characterized in that: said steel rope driver train comprises steel rope, front wheel, back pulley, said forward and backward pulley is installed in the front and back ends madial wall of telescopic section II respectively; One end of said steel rope and telescopic section I be terminal to be connected fixingly, and the other end passes successively behind front wheel and the back pulley to be connected with telescopic section I front end and fixes, and front wheel is connected with the telescopic section III with length of cable between the back pulley and fixes.
