Abstract
The invention relates to a simple machine tool for welding overall standard sections of a tower-type crane and a welding method. Various kinds of existing tower-type cranes are shortened as tower canes, and each tower crane has at least one dozen of standard sections of which the weight is almost close to half of the total weight of the tower crane, and although manufacturers have different machining methods, the problem of relatively large butting size deviation is common. The simple machine tool for welding the overall standard sections of the tower-type crane structurally comprises an underframe (5), wherein a driving mechanism (3) is mounted on the underframe (5); a brake motor (4) is mounted on the outer side where a driving motor (3) is mounted on the underframe (5); an operating table (2) is mounted on the upper part of the underframe (5); a fixing framework (1) is mounted on the underframe (5); a hydraulic system (6) is mounted at the lower end of the underframe (5); and a clamping oil cylinder (7) is mounted at the bottom end of the fixing framework (1). The simple machine tool is used for welding the overall standard sections of the tower-type crane.
Description
technical field:
the present invention relates to facility machine tool and the assembly welding method of the whole standard knot assembly welding of a kind of derrick crane.
background technology:
existing all kinds derrick crane, be called for short the tower machine, standard knot quantity at least tens joints of every, and weight almost approaches half of tower machine gross weight, though each producer's processing method is different, all has the problem that the connection dimension deviation is larger.In most of production, in the technique of docking standard knot, be all that manpower drives the standard knot frock, labour intensity is large, and speed is slow.In the process of part producing, after standard knot docking moulding, lower frock is welded, and welding deformation is larger, and later tower machine installation and use are had to certain influence.The standard knot machining center of the production process special use customized also had, although effectively guaranteed the connection dimension of standard knot, price is very expensive
summary of the invention:
the object of the present invention is to provide a kind of whole standard knot assembly welding of derrick crane facility machine tool of debase the standard joint connection dimension deviation, the time that shortens standard knot processing, reduction labour intensity, can reduce welding deformation, improve the quality of products simultaneously; Use straightforward procedure, less expense, reach the effect of machining center.
the object of the present invention is achieved like this:
the whole standard knot assembly welding of a kind of derrick crane facility machine tool, its composition comprises: underframe, on described underframe, driving mechanism is installed, the outside that described underframe is installed drive motors is equipped with braking motor, described underframe top is equipped with console, on described underframe, fixed frame is installed, described underframe lower end is equipped with hydraulic system, and described fixed frame bottom is equipped with clamping cylinder.
the whole standard knot assembly welding of described derrick crane facility machine tool, described fixed frame can rotate on underframe, is useful on the through hole of fixed standard joint on the annulus of described fixed frame, and the annulus of described fixed frame is connected together by steel bar welding.
a kind of assembly welding method that utilizes the whole standard knot assembly welding of described derrick crane facility machine tool to carry out, welding step is: will need the steel of welding to put in described fixed frame, with clamping cylinder, step up simultaneously, complete after steel skeleton fixing standard knot supplemental support steel and frame welding, in the process of welding, handle drive motors by console and rotate fixed mount, in the time of need to stopping, by console brake activation motor, fixed mount is stopped operating, locate fixed frame with braking motor simultaneously, prevent from occurring the phenomenon of sliding in the process of welding.
beneficial effect:
1. the present invention greatly reduces labour intensity by revolving structure, saves the time of carrying handling.
2. the present invention can raise the efficiency 30% ~ 40% by rotary structure.Labor hour reduces by 20% ~ 30%.
3. the present invention has improved product quality by fixed frame, has reduced the impact of welding deformation.
4. the present invention clamps end face flatness and hole location is improved greatly by fixed frame and hydraulic jack.
5. the present invention can arbitrarily angledly weld by revolving fixed frame, has improved weld appearance and has reduced weld defect simultaneously.
the accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present invention.In figure, 1 is fixed frame, and 2 is console, and 3 is driving mechanism, and 4 is braking motor, and 5 is underframe, and 6 is hydraulic system, and 7 is clamping cylinder.
accompanying drawing 2 is docking operation figure of the present invention.Wherein, 1 is the simple and easy assembly welding lathe of standard knot, and 2 is standard knot.
the specific embodiment:
