Description

Technical Field

[0001] The utility model relates to the technical field of urban rail transit power supply equipment, in particular to a fixing device for a single-sided fixed sectional insulator. Background Technique

[0002] The sectional insulator is an extremely important component at the electrical section of the catenary. It can achieve electrical insulation while maintaining mechanical connection. However, it is not convenient to install the sectional insulator in some special usage scenarios. For example, at the electrical section before entering the upper cover type vehicle depot in the throat area of the curved track section, the traditional double-sided fixed sectional insulator has the drawback of being inconvenient for installation and leveling. If there is a problem with the leveling of the sectional insulator, it will cause problems such as abnormal wear of the pantograph, and in severe cases, it may even cause the catenary to break.

[0003] The publication number CN219947947U discloses a new type of sectional insulator. However, these patents only optimize the structure of the sectional insulator itself to improve safety and the passing performance of the pantograph, and do not optimize the installation of parts, which is not convenient for use under some specific working conditions.

[0004] However, the sectional insulator needs to be installed on both the left and right sides by using the catenary or the herringbone suspension cable. When the installation conditions are not available, it needs to be installed by using the down-anchor guy wire on the civil engineering structure, which increases the complexity of the project and affects the reliability of the project. Therefore, the utility model provides a fixing device for a single-sided fixed sectional insulator. Content of the Utility Model

[0005] In view of the above technical problems, the utility model discloses a fixing device for a single-sided fixed sectional insulator, which includes a flat wrist arm pipe, a sleeve double ear, a guy wire, a connecting plate and an insulating pipe. A group of sleeve double ears are fixedly connected to the tail of the flat wrist arm pipe, and two groups of sleeve double ears are fixedly connected to the head. Two guy wires are respectively connected to the sides of the two groups of sleeve double ears through bolts and split pins. The flat wrist arm pipe is provided with two groups of sleeve double ears. Two connecting plates are respectively connected to both ends of the insulating pipe through bolts. One ends of the two connecting plates are respectively connected to the two groups of sleeve double ears on the middle part of the flat wrist arm pipe through bolts.

[0006] Furthermore, it further includes leveling pull rings. There are two groups of leveling pull rings. Two slideways are respectively suspended by the two groups of leveling pull rings. The two slideways are arranged front and back. The slideways are connected to the leveling pull rings through bolts. The leveling pull rings are respectively provided with suspension holes. Hooks are installed on the suspension holes at both ends of the leveling pull rings. A suspension cable is installed on the hook. The two suspension cables are commonly connected to a sliding clamp. The sliding clamp is slidably installed on the insulating pipe.

[0007] Further, it further includes a contact wire, the contact wire is connected to two slideways, and two insulating rods are fixedly connected between the two slideways through bolts and nuts;

[0008] Further, arc extinguishing rods are respectively arranged on both sides of the slideway;

[0009] Further, the slideway is made of copper alloy material, the insulating rod is made of high-strength polymer material, and the arc extinguishing rod is made of austenitic stainless steel or copper material with good arc extinguishing performance.

[0010] The beneficial effects of the present utility model compared with the prior art are as follows: (1) The present utility model can quickly install the sectional insulator in some special engineering scenarios without relying on the catenary suspension carrier cable, the simple suspension herringbone sling or the special down-anchor guy wire, without damaging the civil engineering structure; (2) When the sectional insulator is set on the line with a super-elevated curve section, it is convenient for construction workers to level, ensuring the safety of train operation; (3) The present utility model makes full use of the existing catenary components, and has good engineering interchangeability and applicability.
