Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

In order that the present disclosure may be more fully described and fully understood, the following description is provided by way of illustration of embodiments and specific examples of the present invention; this is not the only form of practicing or implementing the invention as embodied. The description covers the features of the embodiments and the method steps and sequences for constructing and operating the embodiments. However, other embodiments may be utilized to achieve the same or equivalent functions and sequences of steps.

Fig. 1 schematically shows an application schematic of an energy chain. The protection sleeve in the energy chain is used for sealing and wrapping the pipeline, one end or two ends of the energy chain in the longitudinal direction are fixed on the device, and the two ends can be static, one end is static, the other end moves, or both ends move. In the case of movement, the energy chain flexes with a curvature not less than a defined curvature in one of the directions, while the other direction cannot flex. As in the schematic diagram, one end of the energy chain is fixed at point O and the other end is fixed at point a. The point O is stationary and the point a moves with the device, as indicated by the dashed line, with the energy chain at one end of the point a, flexing to the point B over a defined range of curvature.

Referring to fig. 2 and 3, an energy chain according to an embodiment of the present invention includes a protective sleeve 10, a keel 20, an upper cover rail 30 and a lower cover rail 40. Wherein the protective sleeve 10 includes an upper cover 101 and a lower cover 102 which can wrap a pipeline in a dust-proof manner, the upper cover 101 and the lower cover 102 are flexible tubes each having flexibility, and the protective sleeve 10 is provided to face the bending of the upper cover 101 side with no less than a defined curvature. The pipeline is wrapped in the protective sleeve 10, and the protective sleeve 10 and the keel 20 are synchronously bent.

The upper cover cross bar 30 is fixed on the surface of the upper cover 101, at least one is arranged along the transverse direction perpendicular to the longitudinal direction of the upper cover 101, the lower cover cross bar 40 is fixed on the surface of the lower cover 102, and at least one is arranged along the transverse direction perpendicular to the longitudinal direction of the lower cover 102. The keels 20 are symmetrically arranged on two sides of the protection sleeve 10 along the longitudinal direction of the protection sleeve, and are arranged between the upper cover cross rod 101 and the lower cover cross rod 102, one side of the keels 20 along the longitudinal direction is movably connected with the upper cover cross rod 30, and the opposite side is movably connected with the lower cover cross rod 40. There is a gap between the keel 20 and the protective sleeve 10, and the keel 20 limits the bending of the protective sleeve 10 within a fixed radius of curvature and limits the bending of the protective sleeve 10 facing the lower cover 102 side when the protective sleeve 10 is bent to the upper cover 101 side.

Referring to fig. 4 and 6, the keel 20 includes a flexible centerline axis of rotation 201, upper stop tabs 202 disposed at equal intervals along the longitudinal direction of the centerline axis of rotation 201 on a surface thereof, and lower stop tabs 203 disposed opposite the centerline axis of rotation 201 and aligned with the upper stop tabs 202. Along the longitudinal direction, two opposite sides of the central line rotating shaft 201 are vertically connected with support rods arranged in an aligned manner, and the upper stop piece 202 and the lower stop piece 203 are respectively vertically connected with the support rods positioned on the same side. Opposite ends of the upper stop piece 202 and the lower stop piece 203, which are connected with the support rod, are provided with clamping grooves. The clamping groove on the upper stop piece 202 is matched with the clamping piece on the upper cover cross bar 30, so that the movable linkage of the upper stop piece 202 and the upper cover cross bar 30 is realized; the clamping groove on the lower stop piece 203 is matched with the clamping piece on the lower cover cross bar 40, so that the lower stop piece 203 is movably connected with the lower cover cross bar 40.

When the protective sleeve 10 is bent, the centerline axis of rotation 201 is deformed flexibly therewith, so that when the protective sleeve 10 is bent toward the upper cover 101 side, the adjacent upper stopper pieces 202 gradually approach to abut against each other to define the protective sleeve 10 to be bent within a fixed radius of curvature, and when the protective sleeve 10 tends to be bent toward the lower cover 102 side, the adjacent lower stopper pieces 203 abut directly or indirectly to limit the bending of the protective sleeve 10 toward the lower cover 102 side.

In the embodiment of the present invention, the middle line rotating shaft 201 is provided with the adjusting stop piece 204 between the adjacent lower stop pieces 203, and the interval between the lower stop pieces 203 and the adjusting stop piece 204 is smaller than the interval between the adjacent upper stop pieces 201. When the protective sleeve 10 tends to bend toward the lower cover 102 side, the adjacent lower stopper pieces 203 interfere with the regulating stopper pieces 204, respectively, to thereby restrict the bending of the protective sleeve 10 toward the lower cover 102 side. In the embodiment of the invention, the adjusting stop piece 204 is movably buckled on the central line rotating shaft 201, and the adjusting stop piece 204 is in buckling connection with a supporting rod vertically connected on the central line rotating shaft 201, wherein the supporting rod connected with the adjusting stop piece 204 is in an inverted T shape, one end of the adjusting stop piece 204 is provided with an open rectangular groove, and the adjusting stop piece 204 is movably connected on the central line rotating shaft 201 through the buckling of the rectangular groove and the inverted T-shaped supporting rod. The adjusting stop piece 204 is movably connected with the middle line rotating shaft strip 201, so that the adjusting stop piece 204 is convenient to replace. By replacing the adjusting stop pieces 204 with different sizes, the distance between the lower stop piece 203 and the adjusting stop piece 204 is adjusted, so that the keel 20 has an adjustable stop function, the flexural strength of the energy chain can be adjusted, and finally the adjustment of the overhead length of the energy chain is realized.

The central line rotating shaft strip 201, the upper stop piece 202 and the lower stop piece 203 contained in the keel 20 are integrally injection molded, and the central line rotating shaft strip 201 can extend infinitely, so that the performance is more stable compared with the traditional spliced and stop buckling type keels. In the keel 20, the rest of the components are rigid plastic materials except for the centerline axis 201 which is flexible plastic materials.

In other alternative embodiments, there is no adjustment stop tab 204 between adjacent lower stop tabs 203. The spacing between the lower stop tabs 203 is pre-designed according to overhead length requirements, and when the protective sleeve 10 tends to bend toward the side of the lower cover 102, direct contact between adjacent lower stop tabs 203 limits bending of the protective sleeve 10 toward the side of the lower cover 102.

The keels 20 symmetrically disposed at both sides of the longitudinal direction of the protective sleeve 10 are movably connected with the upper cover rail 30 and the lower cover rail 40, respectively, which are fixed on the contour surface of the protective sleeve 10.

The width of the wave crest surface of the wave crest contour of the upper cover 101 of the upper cover cross bar 30 is smaller than that of the wave crest surface of the wave crest contour of the lower cover 102 of the lower cover cross bar 40, so that when the protecting sleeve 10 is bent towards the side of the upper cover 101, more wave crest folding space can be reserved when the waves of the upper cover 101 are folded together, thereby prolonging the service life of the waves and being not easy to crack.

The upper cover rail 30 includes an upper cover long plate 301, and an upper cover fastening section 302 formed by symmetrically extending outward from the surface of the upper cover long plate 301; the lower cover rail 40 includes a lower cover long plate 401, and a lower cover fastening section 402 formed by symmetrically extending outward at the surface of the lower cover long plate 401, and the width of the upper cover long plate 301 is smaller than the width of the lower cover long plate 402.
