Description

Technical Field

[0001] The utility model relates to the technical field of cable clamps, in particular to a Chinese-shaped 110kv cable clamp. Background Art

[0002] Cable is a device for transmitting electric energy or signals. It is usually a rope-like cable made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering layer. Cables have the characteristics of being energized inside and insulated outside. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, etc. They are all composed of single-strand or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. After the cable is laid, a cable clamp is needed to fix the cable on the bracket. For high-voltage cables, due to the single-core structure, two types of fixing clamps are usually used. One is to fix the single-core cable with a single clamp, and the other is to fix the three-core cable with a clamp.

[0003] At present, for the fixation of three cables, a herringbone clamp is mostly used to stably fix them. The herringbone clamp generally includes a lower hoop body, an upper hoop body and a buffer pad arranged inside the lower hoop body and the upper hoop body. The setting of the buffer pad serves to relieve the pressure on the outer wall of the cable and the herringbone clamp in a fixed state. However, when the herringbone structure of the herringbone clamp is clamping the three cables, the outer edge surfaces of the three cables are in a state of mutual extrusion, and the contact points are in a state of compression and deformation for a long time. Under the long-term laying of outdoor cables, it is easy to cause the stress at the contact position of the cables to be too concentrated and cracks to occur due to the influence of external environmental factors, which in turn affects the normal use of the cables. In view of this, we propose a herringbone 110kv cable clamp. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a herringbone 110kv cable clamp to solve the technical problem that the outer edge surfaces of the three cables are in a state of mutual extrusion when the current herringbone clamp is in use, which easily causes excessive stress concentration and cracking.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: design a 110kv cable clamp in the shape of a triangle, including a lower clamp assembly with an upper clamp assembly detachably mounted on the top, and a cable body detachably wrapped and arranged between the upper clamp assembly and the lower clamp assembly;

[0006] The lower hoop assembly comprises a base with a lower hoop body symmetrically constructed on the top, the opposite ends of the lower hoop body are connected and a protrusion 1 is formed on the bottom;

[0007] The upper hoop assembly comprises an upper hoop body with arc-shaped hoop bodies connected at both ends, the connection between the two ends of the upper hoop body and the arc-shaped hoop body is bent inward to form a second protrusion, and the surfaces of the second protrusion and the first protrusion are detachably provided with a partition assembly;

[0008] The partition component includes a gull-wing partition with a concave outer surface that fits with protrusion one and protrusion two and a convex inner surface. The surface of the gull-wing partition is detachably provided with a gull-wing flexible pad. The gull-wing partition forms a gull-wing structure that fits tightly to the surface of the adapter cable body with the concave outer surface and the convex inner surface as the center. The gull-wing partition and the gull-wing flexible pad are used to separate the cable bodies.

[0009] Preferably, spherical protrusions are symmetrically and equidistantly arranged on both sides of the inner surface of the gull-wing partition, and the outer surface of the gull-wing flexible pad is concave to form a groove structure that is embedded with the protrusions on the inner surface of the gull-wing partition, and the gull-wing flexible pad also forms a gull-wing structure.

[0010] Preferably, spherical holes matching the positions of the spherical protrusions are formed at equal distances on both sides of the outer surface of the gull-wing-shaped flexible pad. The spherical protrusions are abutted in the spherical holes and are used to squeeze the gull-wing-shaped flexible pad when the cable body is wrapped and fixed, so as to form an anti-slip structure with increased local pressure at both ends of the contact position between the cable body and the lower hoop assembly and the upper hoop assembly.

[0011] Preferably, both sides of the outer surface of the upper hoop body are symmetrically constructed with protrusion one and protrusion two, and the protrusion one and protrusion two are integrally connected to form a semicircular arc surface on the surface, and the side of the protrusion one and protrusion two away from the upper hoop body can be detachably installed with a cover hoop component, and a flexible pad one is bonded and fixed on the semicircular arc surface formed by the protrusion one and protrusion two.

[0012] Preferably, the cover hoop component includes an arc-shaped cover hoop detachably connected to protrusion one and protrusion two, both ends of the arc-shaped cover hoop are constructed with connecting plates that fit into protrusion one and protrusion two, and a flexible pad two is bonded and fixed to the inner edge surface of the arc-shaped cover hoop, and connecting holes are equidistantly provided in the connecting plate, and bolts are provided in the connecting holes that can be screwed into protrusion one and protrusion two to fix the cover hoop component to protrusion one and protrusion two.

[0013] Preferably, the opposite ends of the lower hoop body are constructed with a fixing plate 1, and threaded holes 1 are equidistantly provided in the fixing plate 1; the end of the arc-shaped hoop body away from the upper hoop body is constructed with a fixing plate 2, and threaded holes 2 are equidistantly provided in the fixing plate 2; the threaded holes 2 and 1 are internally threadedly provided with screws, and both ends of the screws are threadedly provided with nuts that abut against the fixing plates 2 and 1 to fix the lower hoop assembly and the upper hoop assembly.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By setting a separation component, when the cable body is coated, the outer surface of the cable body is attached to the gull-wing flexible pad. Since a gull-wing partition is set on one side of the gull-wing flexible pad, the cable bodies are separated from each other after being attached to the gull-wing flexible pad, thereby avoiding the phenomenon that the stress at the contact position of the cable bodies is too concentrated and cracks occur due to the cable bodies being attached to each other and continuously compressed and deformed in the coated state, which is beneficial to maintaining the long-term normal use of the cable body. By designing the gull-wing partition as a gull-wing structure, its wing-shaped structure is beneficial to achieve a close fit with the outer surface of the cable body, thereby increasing the contact area between the gull-wing flexible pad and the cable body, and avoiding excessive stress concentration on the contact surface due to the arrangement of the separation component when the cable body is clamped.

[0016] 2. By symmetrically and equidistantly arranging spherical protrusions on both sides of the inner surface of the gull-wing partition, and equidistantly opening spherical holes matching the positions of the spherical protrusions on both sides of the outer surface of the gull-wing flexible pad, when the cable body is clamped, the gull-wing flexible pad is compressed and the spherical protrusions are squeezed toward the gull-wing flexible pad, thereby causing deformation of the corresponding position of the gull-wing flexible pad through the spherical protrusions. By setting the spherical protrusions, the gull-wing flexible pad is squeezed when the cable body is wrapped and fixed, so as to form an anti-slip structure with increased local pressure at both ends of the contact position between the cable body and the lower hoop assembly and the upper hoop assembly, thereby improving the stability of the clamping and fixing of the cable body.
