Abstract
The utility model discloses a take novel cantilever crane structure of high altitude construction car of manual arm, including basic arm, the flexible arm of a plurality of, minimum flexible arm, manual arm, fixed pin axle, flexible hydro-cylinder, the mechanism that draws to contract, leveling support, leveling hydro-cylinder and work platform. The method is characterized in that: the telescopic arms are a plurality of, the telescopic mechanisms are arranged on the telescopic arms and the minimum telescopic arm, the basic arm, the telescopic arms and the minimum telescopic arm are connected with the telescopic mechanisms through telescopic oil cylinders, the manual arm is arranged in the minimum telescopic arm and fixed with the minimum telescopic arm through a pin shaft, the leveling support is fixed at the front end of the manual arm through a leveling oil cylinder, and the operation platform is installed on the upper side of the leveling support. The advantages are that: the manual arm does not need to be additionally designed and processed, and only a plurality of telescopic arms are provided with the stretching and contracting mechanisms. On the premise of increasing the working height and the working range, the cost and the weight of the whole machine are reduced to the maximum extent, and material resources, financial resources and manpower are saved.
Description
Technical Field
The utility model relates to a structural style of high altitude construction car cantilever crane, concretely relates to take novel cantilever crane structure of high altitude construction car of manual arm.
Background
The high-altitude operation vehicle is a special vehicle for transporting workers, using equipment and performing high-altitude operation, and the length of the arm support determines the final working height and range. The existing high-altitude operation vehicle generally adopts a working platform arranged at the front end of an arm support, and the working platform is automatically leveled in the working process through a leveling system. The adjacent arm supports are in flexible connection with each other through the transmission mechanism, the more the arm supports are, the more the arrangement of the connection mechanism is complex, the larger the size of the arm support needs to be designed, the installation and debugging are difficult to control, the dead weight of the whole machine can be increased continuously, and the design and use cost is increased, so that the novel arm support structure of the high-altitude operation vehicle with the manual arm is designed.
Disclosure of Invention
The utility model aims at overcoming the shortcomings of the prior art and providing a novel arm support structure of an overhead working truck with a manual arm.
The technical scheme of the utility model is through following realization: a novel arm support structure of an overhead working truck with a manual arm comprises a basic arm, a telescopic arm, a minimum telescopic arm, the manual arm, a fixed pin shaft, a telescopic oil cylinder, a telescopic mechanism, a leveling support, a leveling oil cylinder and a working platform. The method is characterized in that: the telescopic boom is a plurality of, be equipped with the mechanism that draws in on a plurality of telescopic boom and the minimum telescopic boom, at basic arm and a plurality of telescopic boom, minimum telescopic boom is equipped with flexible hydro-cylinder inside, basic arm and a plurality of telescopic boom, minimum telescopic boom pass through telescopic hydro-cylinder and draw the mechanism connection that contracts, the inside of minimum telescopic boom is arranged in to manual arm, it is fixed with minimum telescopic boom through the fixed pin axle, the leveling support passes through the leveling hydro-cylinder to be fixed at the front end of manual arm, operation platform installs the upside at the leveling support.
The drawing and shrinking mechanism is the prior art.
The front and rear parts of the manual arm are provided with the pin shaft positioning holes, the manual arm can be pulled out to the limiting block manually before the arm support works, and the manual arm and the minimum telescopic arm are fixed together by the pin shaft, so that the working height and the working range of the arm support are increased.
The utility model has the advantages that: by adopting the technical scheme, the manual arm does not need to be additionally designed and processed, only the stretching and contracting mechanisms are needed to be installed on the plurality of telescopic arms, the cost and the weight of the whole machine are reduced to the maximum extent on the premise of increasing the working height and the working range, and the material resources, the financial resources and the manpower are saved.
Drawings
The present invention will be further explained with reference to the drawings and the embodiments.
Fig. 1 is a schematic view of a fully-retracted state of an aerial work vehicle boom with a manual boom.
Fig. 2 is a schematic view of the high-altitude operation vehicle with the hand arm in a state after the hand arm is pulled out.
In the figure: the device comprises a basic arm 1, a telescopic arm 2, a minimum telescopic arm 2-1, a telescopic oil cylinder 3, a telescopic mechanism 4, a manual arm 5, a pin shaft 6, an operation platform 7, a leveling bracket 8 and a leveling oil cylinder 9.
Detailed Description
Referring to fig. 1 and 2, the utility model discloses a basic arm 1, a plurality of flexible arm 2, minimum flexible arm 2-1, manual arm 5, round pin axle 6, flexible hydro-cylinder 3, draw mechanism 4 that contracts, leveling support 8, leveling hydro-cylinder 9 and work platform 7. The telescopic boom type three-dimensional robot is characterized in that a plurality of telescopic booms 2 and a minimum telescopic boom 2-1 are provided with a telescopic mechanism 4, a telescopic oil cylinder 3 is arranged inside a basic boom 1, the plurality of telescopic booms 2 and the minimum telescopic boom 2-1, the basic boom 1, the plurality of telescopic booms 2 and the minimum telescopic boom 2-1 are connected with the telescopic oil cylinder 3 and the telescopic mechanism 4 through the telescopic oil cylinder 3, a manual boom 5 is arranged inside the minimum telescopic boom 2-1 and fixed with the minimum telescopic boom through a pin shaft 6, a leveling support 8 is fixed at the front end of the manual boom 5 through a leveling oil cylinder 9, and an operation platform 7 is arranged on the upper side of the leveling support 8.
The front and rear parts of the manual arm 5 are provided with pin shaft positioning holes, the manual arm 5 can be pulled out to a limiting block manually before the arm support works, and the manual arm and the minimum telescopic arm are fixed together by a pin shaft 6, so that the working height and the working range of the arm support are increased.
