The European patent EP 1781839 of applicant proposes a kind of service module, it includes a framework that can be fixed to vehicle frame and an installation on said frame thus the rotating turret (turrelle) pivoted around a vertical axis, and described rotating turret is configured with multiple process and services component.This service module includes the one group of instrument being arranged on telescopic arm, each telescopic arm is fixed to described rotating turret by a pivoting support (supportarticul é), and this articulated support allows the described telescopic arm pendular movement relative to a pin joint determined.In this service module, telescopic arm maintains the relative angle difference between the pendular movement of described telescopic arm by a mechanical connection devices interconnect with (in the marginal range determined).Such service module makes to be got together more tightly by instrument, thus under the framework of described module restricted volume, particularly width.This service module also provides limited sports independence for instrument, and any the rocking simultaneously preventing them from colliding with each other and preventing one of instrument from experiencing directly impinges on other instruments.
A technical problem relevant to the service module of prior art is in that, minimizes the volume under the framework of module further, the spatial volume that the height under the framework of service module, and whole service module in particular covers during its parts rotate.
Summary of the invention
One theme of the present invention relates to a kind of service module, for being produced in the factory of aluminum by pyrogenic process electrolysis, described module includes: framework and rotating part, described framework can be fixed to vehicle frame, described rotating part is installed on said frame thus pivoting around a generally vertical axis, described rotating part is provided with at least one instrument on the telescopic arm being arranged on described rotating part, described service module farther includes the first supporting structure, this first supporting structure is installed on said frame and is designed to one hopper of supporting, described service module is characterised by: described first supporting structure and described hopper are included in described rotating part, described first supporting structure is designed to support whole described rotating part and install on said frame thus pivoting around described generally vertical axis；And described rotating part includes the second supporting structure, the fixing component of described telescopic arm is arranged on described second supporting structure complementary with described rotating part by the adjustment of attachment arrangement, described attachment arrangement allows the pendular movement of described telescopic arm, described attachment arrangement is fixed to an attachment part of described fixing component, and this attachment part is arranged in a distance of the end from described fixing component.
Most commonly, service module is arranged on the vehicle frame of service-delivery machine, and as described vehicle frame itself, then it is arranged on the moving bridge crane of the serviced component that can move at electrolyzer.Therefore, the rotating part of service module is usually located at or is suspended on below vehicle frame, i.e. remain under the framework of described service module.More specifically, this rotating part is generally installed in rotation on framework it is thus possible to rotate (most commonly around own rotation) around generally vertical axis.Hereinafter, this rotating part is also similarly called rotating turret.
Owing to the first supporting structure is designed to support whole described rotating part and install on said frame thus pivoting around described generally vertical axis, therefore this first supporting structure is usually the top of described rotating part.
Described rotating part is usually provided with one group of fixed instrument, and each instrument of described assembly is mounted on the telescopic arm being fixed to described second supporting structure.It is provided with the telescopic arm of described instrument, described second supporting structure and the attachment arrangement that is placed between described second supporting structure and described telescopic arm is all included in described rotating part.The fixed instrument of this group includes at least one instrument being selected from shell shovel, anodising fixture and crust breaker.
