Cable protection and guide device

Abstract

A cable protection and guide device comprising a number of pairs of right and left spaced side plates articulately connected to each other in a longitudinal direction wherein the plates are identical and interchangeable. Each of the link plates includes an arc shaped concavity, a convex portion and, the convex portion of the next adjacent link plate interengages the arc shaped concavity of the link plate. The arc shaped concavity includes a warp limiting lock groove and the convex portion includes an arc-shaped warp limiting lock piece The arc-shaped warp limiting lock piece of the convex portion interengages the arc-shaped warp-up limiting groove of the arc shaped concavity of link plate so that the warping of the link plates is substantially eliminated. The manufacturing cost for a single link plate used in a cable protection and guide device is reduced by half.

Description

technical field [0001] The invention relates to a cable protection and guiding device, which can safely and reliably protect and guide cables and flexible cables such as hydraulic hoses, pneumatic hoses, optical fibers, etc. These cables are used in working machines, electronic equipment, and industrial robots , Conveying machinery and other industrial machinery, power supply, signal transmission, etc. to these moving machinery or the movable parts of the machinery. Background technique [0002] In the past, as such a cable protection and guiding device, there is a device in which a plurality of link frames are connected in the cable length direction. The connecting plates on the curved outer peripheral side and the curved inner peripheral side of the link plate are configured (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2007-10087 (page 1, figure 2 ) [0004] However, there is a problem in the cable pro...

AI Technical Summary

Problems solved by technology

[0004] However, there is a problem in the cable protection and guiding device of the above-mentioned Patent Document 1, that is, since it is necessary to form a pair of left and right link plates using separate molds on the left and right, the manufacturing cost of the link plate mold cannot be reduced, and it can be used in the desired production. When the shape of the link plate has a variety of functions, there is a problem in mold production that often doubles the production cost of the link plate mold. In addition, there is a problem in the handling of the following parts: when connecting and assembling, it is necessary to align the left and right A pair of link plates is used to properly manage the supply of parts, and the left and right pair of link plates must be selected and identified for assembly, so the connection and assembly work is complicated, and the manufacturing error between the left and right link plates may also affect the bending after completion. movement brings obstacles
