Abstract
The utility model discloses a tower crane coupling mechanism that walks on stage, including welding a pair hangers (1) in hoist upper bracket main structure (4), and weld in installation axle (2) of the stand of walking on stage (3) both sides, walk on stage stand (3) fix through installation axle (2) in hangers (1) on upper bracket main structure (4). This tower crane coupling mechanism that walks on stage adopts at upper bracket main structure welding otic placode, and the coupling mechanism of dress in the otic placode draw -in groove is hung to the stand of will walking on stage for the structure of connectiong mechanism who walks on stage is simple, low cost, and it is convenient to install, firm stable, has avoided the use of round pin axle, need not to guarantee the coaxial precision of round pin axle, has reduced the installation degree of difficulty, has improved the installation effectiveness.
Description
Technical field
The utility model relates to a kind of tower crane and walks on stage, and specifically a kind of tower crane is walked on stage bindiny mechanism.
Background technology
Along with increasing of flat-top tower tower machine type, the scantling of structure of each parts of tower machine also increases thereupon, causes each parts of tower machine difficulty in the process of dismounting to increase.In existing structure, the upper bracket of tower crane adopts double-pin shaft type mostly with walking on stage to be connected, and this version is widely used in the swing type mechanism of tower machine, in, application in large tower machine is also more common.But for superhuge tower machine, this structure can bring very large difficulty to installation: 1, because ultra-large type tower machine block construction size is comparatively large, need squeeze into bearing pin at upper bracket and junction of walking on stage during installation, assembly difficulty is large, efficiency is low, higher to the requirement on machining accuracy of bearing pin; 2, in the actual course of processing, the right alignment of pin shaft hole is often difficult to ensure, because bearing pin and pin-and-hole exist Mismachining tolerance during installation, causes bearing pin to be installed very difficult, affects efficiency of installing software to a great extent.
Utility model content
For above-mentioned prior art Problems existing, the utility model provides a kind of tower crane to walk on stage bindiny mechanism, and structure is simple, with low cost, it is convenient to install, and firm stable avoids the use of bearing pin, without the need to ensureing the coaxial precision of bearing pin, reducing installation difficulty, improving installation effectiveness.
To achieve these goals, this tower crane bindiny mechanism that walks on stage comprises the secondary hangers be welded in hoisting crane upper bracket main structure;
And be welded in the installation shaft of column both sides of walking on stage;
Described column of walking on stage is fixed in the hangers in described upper bracket main structure by installation shaft.
Further, column of walking on stage described in is mounted by installation shaft in the draw-in groove being fixed on and described hangers is offered.
Further, column lower end of walking on stage described in is fixedly connected with by jacking block one is corresponding with the jacking block two of described upper bracket main structure lower end.
Further, the installation shaft be linked in described draw-in groove is fixed by latch.
Compared with prior art, this tower crane walks on stage bindiny mechanism's employing at upper bracket main structure welding otic placode, column of walking on stage is mounted on the bindiny mechanism in otic placode draw-in groove, makes bindiny mechanism's structure of walking on stage simple, with low cost, it is convenient to install, firm stable, avoids the use of bearing pin, without the need to ensureing the coaxial precision of bearing pin, reduce installation difficulty, improve installation effectiveness.

Fig. 3 is hanger structure schematic diagram of the present utility model;
In figure: 1, hangers, 2, installation shaft, 3, column of walking on stage, 4, upper bracket main structure, 5, jacking block one, 6, latch, 7, jacking block two, 8, draw-in groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, this tower crane bindiny mechanism that walks on stage comprises the secondary hangers 1 be welded in hoisting crane upper bracket main structure 4;
And be welded in the installation shaft 2 of column 3 both sides of walking on stage;
Described column 3 of walking on stage is fixed in the hangers 1 in described upper bracket main structure 4 by installation shaft 2.
Further, column 3 of walking on stage described in is mounted by installation shaft 2 in the draw-in groove 8 being fixed on and described hangers 1 is offered.By the effect of draw-in groove 8, when mounted, due to Action of Gravity Field, it is interior and automatically sagging that installation shaft 2 can slip into draw-in groove 8 automatically, make use of the effect of gravity dexterously, and save manpower, cost of installation is low.
Further, column 3 lower end of walking on stage described in is fixedly connected with by jacking block 1 is corresponding with the jacking block 27 of described upper bracket main structure 4 lower end.The column 3 that makes to walk on stage well fits together with upper bracket main structure 4, avoiding walks on stage install after there is the phenomenon of inclination.
Further, the installation shaft 2 be linked in described draw-in groove 8 is fixed by latch 6.Effectively can prevent due to the work strenuous vibration platform that causes the up phenomenon that comes off of play.
This tower crane walks on stage bindiny mechanism when mounted, the installation shaft 2 of column 3 of walking on stage is put into the draw-in groove 8 of otic placode 1, due to Action of Gravity Field, it is interior and automatically sagging that installation shaft 2 can slip into draw-in groove 8 automatically, the tilt phenomenon occurred after installing in order to avoid walking on stage, be bolted on jacking block 27 corresponding to upper bracket main structure 4 lower end by the jacking block 1 of column 3 lower end of walking on stage, the column 3 that makes to walk on stage well fits together with upper bracket main structure 4, avoiding walks on stage install after there is the phenomenon of inclination.
After installation, the installation shaft 2 be linked in draw-in groove 8 loads latch 6, realizes fixation by latch 6, prevent because work strenuous vibration causes the platform up phenomenon that comes off of play.
When tearing machine open, upper end latch 6 and lower bolt are taken down, will walk on stage up to lift with car hosit and pull down.Not at use bearing pin in this structure installment process, installation aspect, make use of the effect of gravity dexterously, and install and save manpower, cost of installation is low.
In sum, this tower crane walks on stage bindiny mechanism's employing at upper bracket main structure welding otic placode, column of walking on stage is mounted on the bindiny mechanism in otic placode draw-in groove, makes bindiny mechanism's structure of walking on stage simple, with low cost, it is convenient to install, firm stable, avoids the use of bearing pin, without the need to ensureing the coaxial precision of bearing pin, reduce installation difficulty, improve installation effectiveness.
