Description

The utility model relates to the field of instrument engineering and can be used to transmit electrical, including informational, signals to equipment from a fixed part of an object to its rotating part with the possibility of changing the technical characteristics of the contact system by replacing modules from the rotating contact device with those belonging to a certain functional range autonomous rotating dimensional modules.

Known rotating collector device for electrical connection of the rotating and stationary parts of the object [1], providing a circular rotation of the rotating part of the rotating collector device, consisting of several parts, which are monoblocks.

The rotating collector device has one significant disadvantage. To change the technical characteristics, if necessary, it is required to develop new monoblocks for replacement as part of a rotating current collector, which significantly lengthens the time for upgrading the device.

Known rotating contact device [2], execution - monoblock, which is a rotating contact system with continuous contact, consisting of a fixed and rotating parts, designed to transmit electrical signals from the stationary part of the object to its rotating part.

A rotating contact device has one significant drawback - if it is necessary to transmit electrical signals of a different type, a change in the design of the monoblock according to the newly developed working design documentation is required, which requires additional time.

Known multifunctional rotating device [3], used as a prototype, containing series-connected waveguide rotating connection, a rotating contact device, a coaxial rotating joint having a common axis of rotation. The waveguide rotating connection and the rotating contact device have internal channels, the axes of which coincide with the common axis of rotation.

The disadvantage of a multifunctional rotating device is that if it is necessary to change the technical characteristics, its composition changes, and it requires the development of working design documentation for the manufacture of new devices associated with a change in technical characteristics.

The technical result of the proposed utility model is a constructive improvement of the rotating contact device, which allows expanding its functionality by replacing modules to obtain new technical characteristics.

The technical result is achieved by the fact that a rotating contact device of block-modular design, consisting of autonomous rotating modules, structurally belonging to a certain size range, having a fixed and rotating parts with various combinations of contact pairs, other characteristics that determine this size range, while autonomous rotating modules of this size range allow you to create a multi-module design of a rotating contact device of block-modular design by hermetically connecting the modules to each other in such a way that the axes of rotation of each module coincide with the axis of rotation of the entire structure, and the outer surfaces of the modules form the outer shell of the housing of the rotating contact device.

The claimed utility model of a block-modular rotating contact device is novel in comparison with the prototype, differing from it in such essential features as the presence in its design of dimensional modules with various combinations of contact systems that form technological rows of functional design purpose.

The claimed utility model can be widely used in special-purpose objects, robotic technical means, tower cranes, hoisting manipulators, and therefore meets the criterion of "industrial applicability".

The presence of technological series of "dimensional" modules of functional design purpose allows you to get an additional advantage of block-modular execution of a rotating contact device in comparison with its monoblock version, which consists in the possibility of creating a database of "dimensional" modules for use when forming an "online order" on the Internet for the development of a rotating contact device with known technical characteristics.

The essence of the proposed rotary contact device block-modular design is illustrated by the drawing of Fig. 1.

A rotating contact device of block-modular design, which includes separate autonomous dimensional modules (three-dimensional layout space, the height and diameter of which are multiples of the base pitch, for example, 2.5 mm), having a fixed and rotating parts of the contact system with various combinations of contact pairs, belonging to a certain size range, as well as the following functional design purpose:

basic module of the size range (pos. 1), which includes rotating (pos. 2) and fixed (pos. 3) parts, with increased requirements for rigidity, strength and electromagnetic compatibility, bearings of the rotation unit (pos. 4), cuff (pos. 5) to ensure the tightness of the rotation unit, docking elements (pos. 6) with other dimensional modules;

modules of the size range (pos. 7) docked with the fixed part of the base module (pos. 1), having in its composition the fixed and rotating parts of the contact system with various combinations of contact pairs, packages of contact pairs (pos. 8), mating parts of electrical connectors of contact pair of the fixed part (pos. 9), rubber ring for hermetic docking (pos. 10), docking elements with other dimensional modules (pos. 11);

module of the size range of the rotating part (pos. 12), which includes mating parts of electrical connectors (pos. 13), a rubber ring for tight docking (pos. 14) with the rotating part of the base module (pos. 1), elements of docking with other dimensional modules (pos. 15);

size range module, which is a protective cover (pos. 16), which includes a rubber ring for hermetic docking with a size module (pos. 17) using docking elements (pos. 18);

axis of rotation of the rotating contact assembly (pos. 19). Rotating contact device block-modular design

works as follows. The base module of the size range (pos. 1) is fixed on the fixed part of the object, the bearings of the rotation assembly (pos. 4) allow the rotating part (pos. 2) to rotate (without limiting the rotation angle) relative to the axis of rotation of the base module, then with the fixed part of the base modules are docked, with the help of docking elements (pos. 6) modules of the size range (pos. 7), which include packages of contact pairs (pos. 8), which, during rotation, perform an inextricable contact connection of electrical circuits that determine this technological series. Thus, electrical signals from the equipment located in the rotating part of the object come through the mating parts of the electrical connectors (pos. 13) of the rotating parts of the dimensional modules to the modules of the size range (pos. 7) and through the mating parts of the electrical connectors of the contact pairs of the fixed part (pos. 9) of a rotating contact device of block-modular design are supplied to the equipment located in the stationary part of the object.

Thus, the block-modular design of the rotating contact device is implemented by joining dimensional modules to each other, while the rotation axes of the contact system of each module coincide with the rotation axis of the entire structure, and the outer surfaces of the modules form the outer surface of the device body.
