Abstract
The utility model relates to an automatic flat-adjusting mechanism for the working terrace of the high-altitude work vehicle, comprising a telescopic arm frame composed of a fundamental arm and a telescopic arm, a fixing wheel, a guiding wheel, a flat-adjusting wheel fixed to the working terrace. The utility model is characterized in that a support arm, a movable wheel group, a flexible element, a fixing guiding wheel are arranged in the arm frame; when the telescopic arm extends forward, the movable wheel group moves forward following the telescopic arm; under the function of the flexible element, the moving speed of the movable wheel group is coordinated with the telescopic arm; when the telescopic arm telescopes, the guiding wheel and the flat-adjusting wheel fixed to the working terrace keep resting and do not rotate, and the working terrace is in horizontal state; the utility model can be used for telescopic arm type and combined type high-altitude work vehicles.
Description
The utility model is a kind of being used for to make job platform keep the mechanism of horizontality automatically on telescopic boom and the hybrid aerial platform.
The job platform of aerial platform such as suspension bucket, hanging basket, platform, cage etc. are to be hinged on the upper end that the lifting jib is gone up a joint most, and different along with the structure of jib and array configuration keep the method for job platform horizontality also different automatically.The simplest method is the suspension bucket formula, by the sagging maintenance balance of deadweight, secondly is parallel four link type.These two kinds of methods are simple in structure, reliable operation, and its shortcoming is: the former job platform is swung with the variation of load position; Latter's pull bar is stressed to be increased with the jib lift angle, and can not be used to the aerial platform with telescopic jib.--conical gear torsion bar type and electromagnetism ()--liquid formula that the auto-leveling mechanism of the aerial platform of band telescopic boom has parallel draw bar, the former compares difficulty, less employing because pull bar is long, rigidity is poor, manufacturing is installed; The latter is to electric very high with reliability requirements Hydraulic Elements.
The purpose of this utility model provides a kind of aerial platform job platform auto-leveling mechanism, it is used to the aerial platform with telescopic jib, the stretching of jib, hoist, when landing, job platform keeps horizontality, and the suffered pulling force of pull bar does not keep constant with the lift angle increase of jib.
Aerial platform job platform auto-leveling mechanism of the present utility model, comprise the telescopic jib, fixed wheel, track adjusting wheel and the fixed operation flat-bed leveling wheel that constitute by basic arm, telescopic boom, fixed wheel is fixed on the jib lower bearing pin, track adjusting wheel is installed on the last hinge of jib, the leveling wheel is installed in job platform and telescopic jib is gone up on the hinge of a joint arm upper end most, and fixes with job platform.It is characterized in that: in jib, be provided with hold-down arm, driving wheel group, flexible member, stator wheel; Hold-down arm is the square-section, and an end is fixed on the basic arm with pivot pin, and the other end is provided with a stator wheel, and the termination is bearing on the telescopic boom through anchor plate; Be welded with one group of guide rail plate on the biside plate in the hold-down arm, the driving wheel group by two driving wheels, be configured to, be arranged on the guide rail plate;
Flexible member is two groups of steel ropes, and one group of one end is fixed on the hold-down arm, walks around a driving wheel of driving wheel group, and the other end is fixed on the telescopic boom; Another is organized an end and walks around and be fixed on the fixed wheel on the telescopic jib lower shaft pin, the other end is walked around the stator wheel that is arranged on the bearing pin of hold-down arm termination, another driving wheel of driving wheel group, walk around again and be installed in the track adjusting wheel on the hinge on the jib, be fixed on the leveling wheel of job platform.
Wherein, the cross section of described hold-down arm is empty stomach box-shaped or vierendeel truss structure.
Described flexible member can adopt chain, or adopts rod member at straight line portion, and flexible member is adopted at other positions.
Driving wheel in the described driving wheel group adopts sprocket wheel or pulley.
Be hinged on the aerial platform of telescopic boom upper end for job platform, be installed in that the track adjusting wheel on the hinge is the leveling wheel that is fixed on the job platform on the telescopic boom.
The utility model has the advantages that: it has kept steel rope (chain) fully--whole advantages of pulley (sprocket wheel) formula levelling gear, can be used for the automatic leveling of telescopic boom and hybrid aerial platform job platform again, solve operation height greater than adopting the automatic leveling problem of failure-free mechanical type job platform on 25 meters the aerial platform.
Working process of the present utility model is: when telescopic boom stretches out forward, the driving wheel group moves forward thereupon, under the effect of flexible member, the moving velocity of driving wheel group is coordinated mutually with telescopic boom, when telescopic boom is flexible, keep static and do not rotate thereby make track adjusting wheel and be fixed on leveling wheel on the job platform, guaranteed that job platform is in horizontality.
Below in conjunction with drawings and Examples, this practicality is further described.
