Abstract

The utility model relates to a crane part, in particular to a suspension arm of a crane, and mainly solves the technical problems of complex structure, high production cost, difficulty in assembly, erection and maintenance and the like of the suspension arm of the crane existing in the prior art. The suspension arm comprises a column body (1), and is characterized in that the top end of the column body (1) is movably connected with a rotatable suspension arm (2); a supporting mechanism is arranged between the suspension arm and the column body; and a guide rail (3) is arranged on the suspension arm (2) and is slidably connected with an electric hoist (5) through a pulley (4).

Description

The hoisting crane suspension arm
Technical field
The utility model relates to a kind of hoisting crane parts, especially relates to a kind of hoisting crane suspension arm.
Background technology
Weight-lifting equipment is divided into transfer crane, crane in bridge type, beam crane and boom crane by device structure; Wherein transfer crane mainly representative equipment be gauntry crane; Crane in bridge type mainly representative equipment is the bridge formation machine, and boom crane mainly representative equipment is a tower crane.Transfer crane is mainly used in work operations such as the up-down, parallel motion of building ground, factory floor and shipyard harbour weight.Transfer crane mainly is made up of lifting overhead traveling crane, girder, supporting leg, traveling gear and electric hydraulic system.Its principle of work is: utilize the lifting overhead traveling crane that is installed on the girder that weight is raised up; The supporting leg upper end connects girder; The lower end connects with traveling gear, through being installed in the driving of motor on the traveling gear, realizes the effect that hoisting crane moves on rail; The overhead traveling crane of lifting simultaneously also can be walked on girder, realizes at last weight is hung the effect that moves on to another place from a place.But the suspension arm structure of these hoisting cranes is comparatively complicated, and productive costs is higher, and assembling is built, keeps in repair also comparatively difficult.
The utility model content
The utility model provides a kind of hoisting crane suspension arm, and it mainly is that to solve the suspension arm structure of existing in prior technology hoisting crane comparatively complicated, and productive costs is higher, and the technical matters that also comparatively is difficult for etc. is built, keeped in repair in assembling.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:
The hoisting crane suspension arm of the utility model comprises shaft, and the top of described shaft is connected with rotatable cantilever, is provided with supporting mechanism between cantilever and the shaft, and cantilever is provided with guide rail, and guide rail slidely connects electric block through pulley.
As preferably, described supporting mechanism includes bonded assembly swing type mechanism on the shaft, supports before swing type mechanism connects, and preceding support top end withstands on one's body the arm of cantilever.
Therefore, the utility model is relatively simple for structure, the assembling, the maintenance all more or less freely, productive costs is lower.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: the hoisting crane suspension arm that this is routine, like Fig. 1, comprise shaft 1, the top of shaft is connected with rotatable cantilever 2, is provided with supporting mechanism between cantilever and the shaft, and cantilever is provided with guide rail 3, and guide rail slidely connects electric block 5 through pulley 4.Support 7 before bonded assembly swing type mechanism 6 on the shaft, swing type mechanism connect, preceding support top end withstands on one's body the arm of cantilever.
The above is merely the specific embodiment of the utility model; But the architectural feature of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.

Claims (2)
