The invention relates to a cantilever beam rotary telescopic crane, which is characterized in that the upper end of an upright post is provided with a rotatable cantilever beam and a swiveling mechanism of the rotatable cantilever beam; the lower side edge of the cantilever is provided with a guide rail; the upright post is formed by butting an upper upright post and a lower upright post; the butted joint of the upper upright post and the lower upright post is provided with a circular rail; the swiveling mechanism is a box body; the upper end of the box body is provided with a swivel mount welded with the cantilever beam; two roller wheels rolling along the circular rail are arranged in the box body; bull gears with the same tooth number are arranged on the same side of each roller wheel; the box body is provided with a speed reducer; and an output shaft of the speed reducer is provided with an output pinion simultaneously meshed with the two bull gears. The guide rail of the cantilever beam is provided with a telescopic beam; an electric block is fixed arranged at the front end of the telescopic beam; and the rear end of the telescopic beam is provided with two roller wheels rolling along the upper surface of the guide rail of the cantilever beam and a speed reducer of a driving roller wheel. Thus, the lift stroke of a lifting hook is prolonged, and the problem that a general cantilever beam crane has a short stroke is solved; besides, the cantilever beam rotary telescopic crane has the advantages of compact structure, legerity, small occupation of space and low cost.
Description
Technical field
The present invention relates to a kind of cantilever beam rotary telescopic crane.
Background technology
The cantilever beam rotary crane generally is used to lift less weight at present.Common cantilever beam rotary crane structure is: surface-based column, in the column upper end rotatable cantilever beam and swing type mechanism thereof are installed, and at the cantilever beam lower side guide rail is installed, the electric block that moves along guide rail is installed on guide rail.The electric block dolly of the hoisting crane of this structure only along the operation of spiral arm beam, is limited by cantilever beam length, thereby the lifting stroke is short; Therefore in order to strengthen stroke, often with the cantilever beam lengthening, the column overstriking, though solved the increase route problem like this, but have that increase in volume, cost increase, heaviness, occupy the bigger shortcoming in space.
Summary of the invention
The present invention provides a kind of cantilever beam rotary telescopic crane that prolongs suspension hook lifting stroke for solving the technical matters that exists in the known technology.
The technical scheme that the present invention takes for the technical matters that exists in the solution known technology is:
A kind of cantilever beam rotary telescopic crane, comprise column, be installed in the rotatable cantilever beam and the swing type mechanism thereof of column upper end, be installed in the guide rail of cantilever beam lower side, and the electric block that moves along guide rail, described column is formed by upper pillar stand and lower pillar stand butt joint, upper pillar stand and lower pillar stand joint are equipped with circular orbit, described swing type mechanism has a casing, the casing upper end is equipped with the swivel mount with the cantilever beam welding, two bearing pins that parallel are installed in the casing, the roller that rolls along circular orbit all is installed on two bearing pins, each roller the same side all is equipped with the big gear wheel of the identical number of teeth, reductor is installed on the casing, is equipped with on the speed reducer output shaft and two big gear wheels while ingear output pinion.
The present invention can also adopt following technical scheme:
Between described electric block and the cantilever beam guide rail telescopic girder is installed, electric block is fixed on the front end of telescopic girder, the rear end of telescopic girder is equipped with two reductors that rotate along the roller and the driving rolls thereof of the rolling of cantilever beam guide rail upper surface, and the telescopic girder rear end also is equipped with the bottom roller that rolls along cantilever beam guide rail lower surface.
Advantage and good effect that the present invention has are:
Owing between electric block and cantilever beam guide rail, telescopic girder is installed, prolonged suspension hook lifting stroke by telescopic girder, and can be along the hand of rotation avoiding barrier, having solved common cantilever beam hoisting crane increases the problem of stroke, and the present invention also has compact conformation, light and handy, occupation of land is little, cost is low advantage in addition.
