Problems solved by technology

When the number of cables and pipelines reaches a certain level, the existing rotary drag chains will be helpless and unable to meet the requirements of use because there is not enough internal space to build these cables and pipelines in the required working space.

Embodiment Construction

[0027] With reference to the accompanying drawings, these figures show a schematic diagram of a large-capacity cable drag chain designed by the present invention. The schematic diagram here shows the series connection of the three-stage planetary gear train. In practical applications, the series stage of the planetary gear train can be selected as required. number.

[0028] The large-capacity cable drag chain of the present invention mainly includes: a plurality of planetary gear mechanisms connected in series to form a differential transmission gear mechanism, each of the planetary gear mechanisms includes a ring gear, a planetary gear, a planet carrier and a sun gear; There are many cables or pipelines; among them, when the first stage ring gear rotates, the rotation angle of the subsequent stages of ring gear gradually decreases, driving the cables and pipelines installed on this towline to rotate regularly to avoid entanglement .

[0029] Specifically, see Figure 1-Figu...

Abstract

The invention proposes a high-capacity rotating drag chain, and the drag chain comprises a differential transmission gear mechanism formed by connecting a plurality of planetary gear mechanisms in series, wherein each planetary gear mechanism comprises a gear ring, a planet wheel, a planet carrier and a sun wheel; the plurality of stages of planetary gear mechanisms are connected in series to form a differential transmission gear mechanism, a plurality of through holes are formed in the output flange and used for containing and fixing cables and pipelines, the cables and the pipelines are installed in the through holes, fixedly connected with the first gear ring, of the output flange, and an annular structure flange with an opening in the outer contour is adopted in the rear stage and used for facilitating installation of the cables and the pipelines; the effective rotation angle of the first-stage gear ring is controlled within + / -180 degrees, and cables and pipelines are prevented from being twisted off. When the first-stage gear ring rotates, the rotation angles of the subsequent stages of gear rings are gradually reduced, cables and pipelines installed on the drag chain are driven to rotate regularly, and the winding phenomenon is avoided.

Description

technical field [0001] The invention relates to a large-capacity cable drag chain, especially suitable for the situation where there are a large number of cables, oil pipes, air pipes, water pipes, etc., and the auxiliary cables and pipelines of the drag chain need to be rotated with the device within a certain rotation angle. Background technique [0002] Since its birth in 1953, drag chains have been widely used in various reciprocating motion occasions, which can effectively protect and pull built-in cables, oil pipes, air pipes, water pipes, etc. In the case of rotary reciprocating motion, the current cable capacity of the rotary drag chain is extremely limited, and it can only solve the application conditions with a small number of cables and pipelines. When the number of cables and pipelines reaches a certain level, the existing rotary drag chains will be helpless and unable to meet the requirements of use because there is not enough internal space to build these cable...
