Technical Field:

The utility model belongs to the technical field of electronic converters, in particular to a multi-functional central collector device for supplying power to large-scale mobile electric equipment such as stacking and pick machine.

Background Art:

With the rapid development of the mechanical device industry in China, large-scale mobile power supply equipment is more and more widely used. Moreover, the intelligent means of equipment are becoming higher and higher, and the accuracy of equipment control is also becoming higher and higher, including all kinds of high-precision and high-sensitivity detection signals, video, network, audio and other signals. Therefore, the requirements for transmission become stricter. Optical fiber is needed on many occasions, but it is well known that optical fiber can not be folded, which makes the rotating transmission of signals need specific equipment. At this stage, the rotating power supply equipment supporting such equipment mainly relies on imports, which is not only expensive, but also can not fully meet the performance and working condition requirements of domestic equipment.

How to integrate the power supply signal, common control signal and optical fiber communication signal together to provide stable and reliable transmission of signals for rotating equipment. Providing a stable multi-functional central collector device has become an urgent problem to be solved.

Contents of Utility Model:

The utility model aims to solve the above shortcomings and provide a multi-functional central collector with stable performance.

This technical solutions for achieving the objectives mentioned above are:

The utility model provides a multi-functional central collector device, which is mainly composed of an infinite rotating optical fiber coupler, which is connected with a slip ring hollow shaft and an integrated slip ring through a bearing, then connected with a power ring bar, a copper slip ring and a power ring carbon brush through a transmission seat, and then connected with a lower bearing seat and a lower hollow shaft through a bearing.

The utility model adopts the structure of under drive. The rotary support of the main engine drives the lower bearing seat of the central collector to rotate. Since the lower bearing seat is connected with the copper ring, the power slip ring, collector slip ring and infinite rotating optical fiber coupler also rotate with the rotary support, realizing the relative rotation of the slip ring and the housing. The rotary support of the main engine drives the lower bearing seat of the central collector to rotate. Since the lower bearing seat is connected with the copper ring, the power slip ring, collector slip ring and infinite rotating optical fiber coupler also rotate with the rotary support, realizing the 360° free rotation of the collector. High-current conductive copper slip ring and power ring carbon brush are adopted. Outside the utility model of multi-functional central collector device, a plastic spraying electrical element cabinet with high protection grade is adopted, so that the internal live parts are completely electrically isolated from the outside.

The power and control signals come from the transformer box, pass through the cable drum, enter the incoming protective cover of the central collector, and then connect to the collector slip ring contact or the wiring terminal. Then, they are transmitted to the wiring terminal of the outgoing line by the friction contact between the conductive slip ring and the carbon brush, and then transmitted to the main control room by cable, completing the whole set of balanced transmission of current signals and control signals.

Beneficial effects: Through the system, the device can integrate the power supply signal, common control signal and optical fiber communication signal together to provide stable and reliable transmission of signals for rotating equipment. The device effectively solves the problem of cable knotting and entangling after the rotating equipment transmits signals through the hard-wired cables. It has excellent conduction characteristics and good electrical isolation performance. Modular components are adopted, so that it is easy to maintain and can be widely manufactured and used.
