Description
Technical field
The utility model relates to aerial platform, is a kind of crawler lifting mechanism for the caterpillar belt self-walking type high-altitude operation platform specifically.
Background technology
Continuous change and progress along with life and production, the application of aerial platform is more and more extensive, arrange and install at building, house ornamentation, electric operating, megastore, large-scale cultural and sports activity site facility, light rail and bridge construction, main equipment is being brought into play more and more important effect such as many aspects such as the daily attention of aircraft etc. and cleanings.
In order to adapt to the demand of productive life, just require the structure of aerial platform constantly to develop and innovate.With regard to the various forms of present aerial platform, caterpillar belt self-walking type is relatively commonly used, and compares such as wheeled self-propelled, in-vehicle etc. of other forms of Operation Van, and obvious advantage is also arranged.The traveling gear of caterpillar belt self-walking type Operation Van adopts crawler belt, and is large with contact area of ground, little to surface pressure, can be used for office operation, and other form Operation Vans nearly all land with tire, can't be used for the road conditions such as indoor floor; And wheeled self-propelled and in-vehicle can only be at ground situation pavement usages preferably, can not satisfy the power industry of major part operation in the open air uses, and the rubber belt track self-propelled aloft working platform has been filled up Operation Van's blank in this regard, can adapt to the open-air road conditions of various complexity.
In use also there are a lot of problems in existing rubber belt track self-propelled aloft working platform, and as when running into the less passage of size, because its width is larger, width at will the adjustment period passes in and out just cumbersome again; Also have when running into the special road conditions such as climbing, because that crawler belt and chassis are separated by is too near, neither be very convenient.Along with the various variations in the life, also more and more higher to the operating needs of rubber belt track self-propelled aloft working platform, relatively be badly in need of for a kind of rubber belt track self-propelled aloft working platform that can adapt to various road conditions.
Summary of the invention
The purpose of this utility model provides a kind of crawler lifting mechanism for the caterpillar belt self-walking type high-altitude operation platform, can regulate collection height and the width of crawler belt Operation Van by this mechanism, flexibly mobile, can pass through very easily the less door of size of some building, enter office work, also have good hill climbing ability, can be competent at the work requirements of the open-air road conditions of various complexity.
Described a kind of crawler lifting mechanism for the caterpillar belt self-walking type high-altitude operation platform comprises crawler belt oil cylinder and the lifting mechanism that is connected with crawler belt, it is characterized in that: described lifting mechanism is comprised of upper and lower connecting plate, left and right interior plate, left and right outer panel, the upper end of left and right interior plate and left and right outer panel is hinged with the interior outside at upper plate two ends respectively, the lower end is hinged with the interior outside at lower plate two ends respectively, and left and right interior plate and left and right outer panel form left and right two parallelogram brackets with upper and lower connecting plate dual-side respectively; Lifting mechanism is inboard by left and right interior plate and aerial platform welding of underframe, and the outside is by left and right outer panel and crawler belt welding; Upper plate and the aloft work under-carriage of crawler belt oil cylinder two ends difference lifting mechanism are hinged.
Described left and right interior plate be connected outer panel and form left and right two parallelogram brackets with upper and lower connecting plate dual-side respectively and connect by four parallel connecting rods, the two ends of four connecting rods are separately fixed on four hinge-points of left and right two parallelogram brackets, and form the cylinder support that one or six faces are parallelogram with left and right two parallelogram brackets.
The rod end of described crawler belt oil cylinder is hinged by the cylinder support of the central part of the upper plate of rod end bearing pin and lifting mechanism, and the cylinder barrel end of crawler belt oil cylinder is hinged by cylinder barrel end bearing pin and aloft work under-carriage upper cylinder bearing.
The utility model is flexible by control crawler belt oil cylinder, promotes two parallelogram four-bar mechanisms, and then the drive crawler belt carries out lifting.Because the characteristic of parallelogram four-bar mechanism has guaranteed crawler belt in lifting process, steady kiss the earth can not tilt all the time.At a distance of certain horizontal throw, even if so that walk in the road conditions of complexity, the car load center of gravity also can be positioned at the zone in the middle of two mechanisms all the time, thereby makes smooth running between the two parallelogram four-bar mechanisms of connecting rod left and right sides.When the crawler belt oil cylinder was retracted to minimum stroke, this mechanism drew crawler belt in, made car load have minimum collection width and collection height, can arrive indoor target area work by size less door and corridor flexibly; When the crawler belt oil cylinder was elongated to range, this mechanism stretched crawler belt downwards, made underframe away from ground, thereby made car load have maximum hill climbing ability, can adapt to the open-air road conditions of various complexity, and the stair that also can climb up certain slope arrive designated area work.
The utility model has greatly promoted alerting ability, hill climbing ability and the range of use of rubber belt track self-propelled aloft working platform, can fully satisfy the user demand of various indoor and field works in the real life.
