Abstract
The utility model provides a center collector which comprises a base and a cover casing. A collector rotating base and a rotating shaft are arranged in the cover casing. A small copper ring carbon brush group, a medium copper ring carbon brush group and a large copper ring carbon brush group are respectively arranged at the upper part of the cover casing from bottom to top. Wiring plates are arranged between the small copper ring carbon brush group and the medium copper ring carbon brush group and between the medium copper ring carbon brush group and the large copper ring carbon brush group. The center collector is characterized in that one end of the rotating shaft is fixedly connected with a mercury slip ring; the upper end of a Profibus bus passes through the copper ring, and is connected with a wiring end at the upper part of the mercury slip ring; and the lower end of the Profibus bus is connected with a wiring end at the lower part of the mercury slip ring. The center collector has excellent conductivity in occasions of high rotating speed, low impedance, low interference and the like, and delivers a weak signal.
Description
Technical field
The utility model relates to a kind of plant equipment for the above rotation of needs 360 degree provides the centre collector ring of electric power.
Background technology
Tradition centre collector ring is exactly that a rotating parts on fixed axis is to transmit the current collecting equipment of electric power, electric current is sent on copper alloy ring by compound brush, according to the different model of current collecting equipment, for guaranteeing maximum Surface Contact and stable electric current, we to ensure the constant contact between carbon brush and slip ring, are the ideal equipment of the mobile transmission of electricity of revolution by variable unique spring design.
Along with the extensive use of frequency converter, the communication issue of frequency converter can more and more come into one's own, particularly realize the control system of PLC and inverter communication based on PROFIBUS bus, reliability, the maintainability of whole system will be strengthened, realize distributed control, reduce the work risk of system and improved response speed and the control precision of system, thereby effectively realized the communication issue of frequency converter and PLC.But for the plant equipment of the above rotation of needs 360 degree, this PROFIBUS bus requirements is realized signal conduction by centre collector ring reliably, and traditional carbon brush copper ring conducted signal mode can not meet the technical requirement of Profibus bus communication.
Summary of the invention
The purpose of this utility model is to provide a kind of at high rotating speed, Low ESR, and the occasions such as low interference have good electric conductivity and are used for realizing the centre collector ring that small-signal is transmitted.
The technical scheme that the utility model is realized above-mentioned purpose is, a kind of centre collector ring, comprise base and case, in case, there is current-collector rotating base and rotating shaft, the top of case is separately installed with small copper ring carbon brush group, middle copper ring carbon brush group and large copper ring carbon brush group from the bottom to top, between small copper ring carbon brush group and middle copper ring carbon brush group and between middle copper ring carbon brush group and large copper ring carbon brush group, all there is patchboard, its innovative point is: one end of rotating shaft is fixedly connected with mercury slip ring, and the upper end of Profibus bus is connected with mercury slip ring top terminals through copper ring; The lower end of Profibus bus is connected with mercury slip ring bottom terminals.Mercury slip ring described in the utility model is again rotary connector, swivel joint, mercury contact, conductive contact, conducting ring, collector ring, collecting ring etc.
The upper end of Profibus bus is enclosed with at least double layer of metal flexible pipe.
The utility model adopts mercury slip ring, it is different from traditional carbon brush slip-ring, adopting liquid mercury is conducting medium, stiff end and round end are integrated, no longer need carbon brush, therefore most suitable at slip ring the inside transmission of signal and control electric current, be more suitable for the inefficient field of traditional slip ring.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of centre collector ring, comprise base 1 and case 2, in case 2, there is current-collector rotating base 3 and rotating shaft 4, the top of case 2 is separately installed with small copper ring carbon brush group 5, middle copper ring carbon brush group 7 and large copper ring carbon brush group 8 from the bottom to top, between small copper ring carbon brush group 5 and middle copper ring carbon brush group 7 and between middle copper ring carbon brush group 7 and large copper ring carbon brush group 8, all there is patchboard 9, its innovative point is: one end of rotating shaft 4 is fixedly connected with mercury slip ring 10, and the upper end 11-1 of Profibus bus 11 is connected with mercury slip ring 10 top terminals through copper ring; The lower end 11-2 of Profibus bus 11 is connected with mercury slip ring 10 bottom terminals.Patchboard 9 of the present utility model passes through to connect the cable on copper ring, thereby connects control cables line and the power electric cable of rotating parts needs above to user.
As shown in Figure 1, the upper end of Profibus bus 11 is enclosed with at least double layer of metal flexible pipe 12.In the utility model, Profibus bus 11 is enclosed with three layers of metal hose 12 that needs heat-shrinkable T bush insulation through copper ring part.
The utility model, installing when mercury slip ring, is first fixed on mercury slip ring one end of rotating shaft 4, ensures the axiality of its installation, can affect useful life of slip ring with the axiality of rotating shaft 4.UP mark on its less important attention mercury slip ring 10, guarantees that upwards installation direction is consistent.And the binding post providing with mercury slip ring 10 must be provided, and can ensure like this useful life, definitely can not directly wire be soldered on mercury slip ring 10 binding posts.In order to avoid to greatest extent electromagnetic interference, the Profibus bus 11 of large electric current copper ring inside is placed in metal hose 12 simultaneously, and metal hose 12 can be made of the metal hose with two-layer thermoplastic sleeve pipe (12).To directly be connected with mercury slip ring terminal through the Profibus private cable in copper ring, reserved 25 meters long direct and input/output terminal equipment connections in two ends.
