Description

Technical Field

[0001] The utility model relates to the technical field of cross arms, in particular to a wire fixing device for a distribution network insulating cross arm. Background Technique

[0002] The cross arm is an important component in the pole tower. Its function is to install insulators and fittings to support the conductors and lightning conductors and keep a certain safe distance according to regulations. It can be divided into: iron cross arm, porcelain cross arm, and composite insulating cross arm according to materials.

[0003] The current insulating cross arms on the market are composed of a cross arm main body, connecting fittings, and hanging wire fittings. The hanging wire fittings are mainly used for placing and fixing the conductors. The fixing between the conductors and the hanging wire fittings is mostly carried out by bundling with metal wires. The contact surface between the metal wires and the conductors is small. After bundling and fixing, the metal wires will cause greater extrusion on the conductors. During the later use process, when the conductors are blown by the wind, the friction between the conductors and the metal wires is aggravated, which is extremely likely to cause the conductors to be damaged. In addition, some insulating cross arms use installation clips and bolts to fix the conductors. In high-altitude operations, the installation of bolts is inconvenient, and the contact surface between the installation clips and the conductors is also small, which is also likely to cause damage to the edge where the conductors are fixed. Based on this, a wire fixing device for a distribution network insulating cross arm is provided. Content of the Utility Model

The fixing components are used for quickly fixing between the conductor and the wire limiting seat;

[0006] The fixing components include connecting cylinder columns and bundling plates;

[0007] The connecting cylinder columns are symmetrically fixed on both sides of the outer wall of the wire limiting seat. There are two bundling plates, and the two bundling plates are respectively fixed on one side of the two connecting cylinder columns;

[0010] The anti-slip film is adhesively fixed to one end face of the bundling plate that is wound and attached to the outer wall of the wire. A plurality of anti-slip films are horizontally distributed on a single bundling plate, and the anti-slip films are used to increase the frictional resistance between the bundling plate and the wire.

[0011] As a further solution of the present utility model: The wire suspension fitting further includes a support seat, a wire releasing pulley hanging hole, and a wire fixing groove;

[0012] The support seat is fixed to one end of the cross arm main body away from the connecting fitting, and the wire releasing pulley hanging hole is opened on one side of the support seat and penetrates to the other side of the support seat;

[0013] The wire limiting seat is fixed to the top of the support seat, and the wire fixing groove is integrally formed on the top of the wire limiting seat and penetrates through both sides of the wire limiting seat.

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a distribution network insulated cross arm conductor fixing device includes an insulated cross arm 1 composed of a cross arm main body 101, a connecting fitting 102, and a suspension fitting 103. The connecting fitting 102 is fixed to one end of the cross arm main body 101. The suspension fitting 103 includes a support base 1031, a wire pulley hanging hole 1032, a suspension fitting 103, and a conductor fixing groove 1034;

[0024] The support base 1031 is fixed to the end of the cross arm main body 101 away from the connecting fitting 102. The wire pulley hanging hole 1032 is opened on one side of the support base 1031 and penetrates to the other side of the support base 1031;

[0025] The conductor limiting seat 1033 is fixed to the top of the support base 1031. The conductor fixing groove 1034 is integrally formed on the top of the conductor limiting seat 1033 and penetrates both sides of the conductor limiting seat 1033;

[0026] On both sides of the outer wall of the conductor limiting seat 1033, there is a fixing component 2, and the fixing component 2 is used for quickly fixing between the conductor 3 and the conductor limiting seat 1033;

[0027] The fixing component 2 includes a connecting cylinder column 201, a binding plate 202, and an anti-slip rubber sheet 203;

[0028] The connecting cylinder columns 201 are symmetrically fixed on both sides of the outer wall of the conductor limiting seat 1033. There are two binding plates 202, and the two binding plates 202 are respectively fixed to one side of the two connecting cylinder columns 201;

[0029] The binding plate 202 is flat, and the conductor 3 is spirally wound outside the conductor 3 through the two flat binding plates 202 to realize the connection and fixation between the conductor 3 and the conductor limiting seat 1033;

[0030] The anti-slip film 203 is adhesively fixed to one end face of the bundling plate 202 that is wound and attached to the outer wall of the wire 3. A plurality of anti-slip films 203 are horizontally distributed on a single bundling plate 202, and the anti-slip films 203 are used to increase the frictional resistance between the bundling plate 202 and the wire 3.

[0031] In this embodiment: It should be noted that: An insulating sheath is provided on the outer side of the cross-arm main body 101, and the connecting fitting 102 and the external clamp cooperate to install and fix the insulating cross-arm 1 to the utility pole.

[0032] The bundling plate 202 is made of aluminum alloy material, and the initial state of the bundling plate 202 is in a state tending to be straight, and both ends of the two bundling plates 202 far from the connecting cylinder 201 are far from the wire limiting seat 1033, so as not to affect the placement of the wire 3 inside the wire limiting groove 1034.

[0033] When the wire 3 is placed inside the wire limiting groove 1034, the two bundling plates 202 can be bent and wound respectively, so that the bundling plate 202 is spirally wound around the outer side of the wire 3. In this way, the connection between the bundling plate 202 and the wire 3 is realized. At the same time, through the fitting of the protective film 203 of the bundling plate 202 and the wire 3, the wire 3 can be subjected to a large frictional force, so as to realize the horizontal limit of the wire 3, and then realize the connection and fixation of the wire 3 and the guiding limiting seat 1033.

[0034] Through the cooperation of the above-mentioned multiple parts, the quick installation and fixation of the wire 3 can be realized. Compared with the traditional metal wire bundling operation, the flat bundling plate 202 can effectively increase the contact area with the wire 3, and while providing sufficient limiting frictional force, it can effectively avoid excessive extrusion damage to the surface of the wire 3, improve the subsequent use safety of the wire 3, and the overall operation is simple and convenient for construction and installation.

[0035] Please refer specifically to Figures 1 to 3 , the two connecting cylinders 201 are distributed below both sides of the wire fixing groove 1034, and the center line of the connecting cylinder 201 and the center line of the wire fixing groove 1034 are located on the same horizontal plane;

[0036] The two bundling plates 202 are distributed in a 180-degree ring centered on the wire limiting seat 1033, and the spiral directions of the two bundling plates 202 wound around the wire 3 are in opposite states.

[0037] In this embodiment: Since the center line of the connecting cylinder 201 and the center line of the wire fixing groove 1034 are located on the same horizontal plane, after the two bundling plates 202 bundle and fix the wire 3, the center line of the wire 3 is aligned with the center line of the wire fixing groove 1034;

[0038] It should be noted that when the bundling plate 202 is spirally wound around the outer side of the wire 3, there is a gap in the middle of the spiral track of the bundling plate 202. Moreover, with the structure that the spiral directions of the two bundling plates 202 wound around the wire 3 are opposite, when an external force acts on the wire 3 and horizontally pulls the two bundling plates 202, the forces on the two bundling plates 202 are opposite. One bundling plate 202 extends and the other bundling plate 202 contracts. While fixing the wire 3, a certain buffer space is provided for the wire 3.

[0039] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
