Abstract
The invention discloses a reinforced boom frame structure of a jib crane. A tripod is arranged at the bottom of a bottom knuckle boom, middle booms are arranged at the top of the bottom knuckle boom through connecting sheets, a plurality of middle booms are connected together by the connecting sheet, a top knuckle boom is arranged at the tail end of the last middle arm through the connecting sheet, and a support is formed at the front end of the top knuckle boom, and thus a frame body of the bottom knuckle boom, the middle booms and the top knuckle boom is formed; a square frame formed by outer rods is positioned at the outermost side, the about one-fourth position of the adjacent outer rod is connected and fixed by a reinforcing rod I, and one end of each reinforcing rod I is connected and fixed together with the farther end of the adjacent reinforcing rod I by a reinforcing rod II. According to the reinforced boom frame structure of the jib crane, when a heavy object is hoisted, the boom frame can be reinforced by the reinforcing rods I and the reinforcing rods II, so that breaking damage of the boom frame is avoided; and the reinforced boom frame structure of the jib crane is simple and novel in design, and is novel.
Description
Technical field
The present invention relates to a kind of arm derrick crane heavier-duty jib structure.
Background technology
The feature of arm derrick crane is substantially identical with crane in bridge type.Can circle and on idle job, be used for the work such as outdoor handling and installation, have span winch, floating crane, mast crane, wall sleeving crane and deck crane etc.
Arm derrick crane comprises: lifting mechanism, luffing mechanism, rotating mechanism.Rely on the interoperation of these mechanisms, weight lifting and carrying in certain cylindrical space can be made.Arm derrick crane is installed on vehicle more or on other forms of transport (movement) instrument, constitutes and run boom type rotary crane.As automobile crane, rubber tired crane, tower crane, high pedestal jib crane, floating crane, locomotive crane etc.
The jib of existing arm derrick crane, in the process used, if the overweight damage that often easily fractures of hanging piece, particularly when just opening and hanging, horizontal jib structure is easy to fracture, affect the normal use of people, can not meet the use needs of people, how designing a kind of heavier-duty jib structure becomes people's problem anxious to be resolved.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of arm derrick crane heavier-duty of research and design jib structure, in order to solve the jib of existing arm derrick crane, in the process used, if the overweight damage that often easily fractures of hanging piece, affect the normal use of people, the shortcoming that the use that can not meet people needs.The technological means that the present invention adopts is as follows:
A kind of arm derrick crane heavier-duty jib structure, comprising: spider, coxopodite arm, intermediate arm, epimerite arm, connecting strap, support, outer bar, reinforcing rod one and reinforcing rod two; Described coxopodite arm bottom is provided with spider, top is provided with intermediate arm by connecting strap, multiple described intermediate arm is linked together by connecting strap, the end of last intermediate arm is provided with epimerite arm by connecting strap, described epimerite arm front end is provided with support, the support body of composition coxopodite arm, intermediate arm and epimerite arm, outermost is the square frame of outer bar composition, long 1/4th places of close bar of adjacent outer bar are connected and fixed by reinforcing rod one, and one end of each described reinforcing rod one and one end far away of reinforcing rod one adjacent with it are connected and fixed by reinforcing rod two.
Be provided with turning cylinder as preferred described spider lowermost end, described support is triangular reinforced structure, and cantilever tip is provided with rotor wheel.
The vertical bar preventing connecting strap place from rotating is fixed with as preferred described connecting strap two ends.
Compared with the prior art, a kind of arm derrick crane heavier-duty jib structure of the present invention, composition coxopodite arm, the support body of intermediate arm and epimerite arm, outermost is the square frame of outer bar composition, long 1/4th places of close bar of adjacent outer bar are connected and fixed by reinforcing rod one, one end of each reinforcing rod one and one end far away of reinforcing rod one adjacent with it are connected and fixed by reinforcing rod two, form the jib structure of heavier-duty, allow people when the object slinging heavier, reinforcing rod one and reinforcing rod two can be reinforced jib, avoid the damage that fractures of jib, structure is simple, novel in design, it is a kind of Novel arm posture Crane Jib Structure.
