Description

Technical Field

[0001] The utility model belongs to the technical field of rigid contact networks for rail transportation, and in particular relates to an integrally insulated rigid contact network suspension device. Background Art

[0002] The rigid contact network suspension device is mainly used in the contact network power supply system of urban rail transit. It is generally installed at 1′ on the top of the tunnel and adopts two types of embedded bolts or embedded grooves, such as Figure 7-9 As shown, an insulating cross brace 3' is installed under the embedded bolts or embedded grooves 2', a suspension device (insulator) 4' is installed under the insulating cross brace 3', a positioning clamp 5' is installed under the suspension device (insulator) 4', and a busbar 6' is fixed in the positioning clamp 5'. When the train passes, the pantograph draws power from the busbar to pull the train forward. However, with the improvement of line insulation performance, the creepage distance of this type of busbar hoisting support using a steel beam structure is too small, affecting the insulation performance of the system. Secondly, due to errors in the tunnel construction process, there is insufficient space at the top of the tunnel, which hinders the installation of the insulating cross brace.

[0003] Based on the above-mentioned defects of the existing contact network suspension device, it is necessary to propose improvements. Utility Model Content

[0004] The technical problem solved by the utility model is to provide an integrally insulated rigid contact network suspension device. The utility model aims to increase the insulation performance of the contact network suspension system and solve the problem that the steel insulating cross brace is inconvenient to install.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by this utility model is:

[0007] As a further limitation of the above solution, the integral insulating suspension bracket is made of a glass fiber unsaturated polyester composite material to form an integral bracket structure.

[0008] As a further limitation of the above solution, the integral insulating suspension bracket is manufactured into different models according to the installation height requirements of the busbar and the original error of the tunnel.

[0009] To further limit the above scheme, the embedded connecting part adopts an embedded bolt type, and the embedded bolt type includes an embedded bolt, the upper end of the embedded bolt is embedded in the top of the tunnel, and the top of the integral insulating suspension bracket is provided with a mounting hole for cooperating with the embedded bolt, and the mounting hole of the integral insulating suspension bracket is put on the embedded bolt and locked by a nut.

[0010] To further limit the above scheme, the embedded connecting part adopts an embedded groove type, and the embedded groove type includes an embedded groove and a T-bolt. The embedded groove is embedded in the top of the tunnel, and the T-head of the T-bolt is adapted in the embedded groove. The top of the integral insulating suspension bracket is provided with a mounting hole for cooperating with the T-bolt, and the mounting hole of the integral insulating suspension bracket is put on the T-bolt and locked by a nut.

[0011] As a further limitation of the above solution, ribs are provided on the side surfaces of the integral insulating suspension bracket.

[0012] A further limitation of the above scheme is that the upper part of the bus positioning wire clamp is fixedly connected to the mounting hole of the lower part of the integral insulating suspension bracket through a fixed connection hole and a fixing bolt, and the lower part of the bus positioning wire clamp is provided with a bus mounting groove for matching the shape of the bus.

[0013] The advantages of this utility model compared with the prior art are:

[0014] 1. This solution uses an integral insulating suspension bracket in the contact network suspension device, which has better insulation performance than the steel insulating cross brace used in the prior art and increases the electrical performance requirements of the system;

[0016] 3. The overall insulation suspension bracket structure in this solution is simpler, with high construction efficiency, convenient adjustment, and simple operation and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0028] See also Figure 1-9 , describe in detail the embodiments of the present utility model.

[0029] Example 1: An integrally insulated rigid contact network suspension device, see Figure 1As shown, it includes a pre-embedded connector 1, an integral insulating suspension bracket 2, a busbar positioning wire clamp 3 and a busbar 4. The pre-embedded connector 1 is pre-embedded in the tunnel top 5. The upper part of the integral insulating suspension bracket 2 is fixedly connected to the tunnel top 5 through the pre-embedded connector 1. The lower part of the integral insulating suspension bracket 2 is fixedly connected to the busbar positioning wire clamp 3. The busbar 4 is connected below the busbar positioning wire clamp 3.

[0030] This embodiment uses an integral insulating suspension bracket instead of the conventional steel insulating cross brace. This provides greater adaptability, addresses the high tolerance requirements of the insulating cross brace on the tunnel structure, and enhances installability. The integral insulating bracket structure is simpler, resulting in efficient construction, easy adjustment, and simplified operation and maintenance.

[0031] Example 2: This example is a further limitation made on the basis of Example 1. Specifically, the integral insulating suspension bracket 2 is an integral bracket structure made of glass fiber unsaturated polyester composite material.

[0032] In this embodiment, the integral insulating suspension bracket is made of glass fiber unsaturated polyester composite material, which has strong electrical insulation performance and high mechanical properties, and can withstand and transmit loads in all directions on the bus.

[0033] This embodiment uses an integral insulating suspension bracket made of composite materials, which has better insulation performance than the previous steel insulating cross brace and increases the electrical performance requirements of the system.

[0034] Preferably, the integral insulating suspension bracket 2 is manufactured into different models according to the installation height requirements of the busbar and the original error of the tunnel. When in use, the appropriate model can be selected for installation according to the installation height requirements of the busbar and the original error of the tunnel.

[0035] Preferably, the side surface of the integral insulating suspension bracket 2 is provided with ribs 2-1 for ensuring the mechanical properties of the bracket and increasing the strength of the bracket.

[0036] Example 3: This example is a further limitation made on the basis of Example 1. Figure 1-3 As shown, the embedded connector 1 adopts an embedded bolt type, and the embedded bolt type includes an embedded bolt 1-1. The upper end of the embedded bolt 1-1 is embedded in the tunnel top 5, and the top of the integral insulating suspension bracket 2 is provided with a mounting hole for cooperating with the embedded bolt 1-1. The mounting hole of the integral insulating suspension bracket 2 is sleeved on the embedded bolt 1-1 and then locked by a nut.

[0037] In this embodiment, the embedded connector is in the form of embedded bolts, and the integral insulating suspension bracket is directly fixed by the embedded bolts, which has a simple structure and is easy to operate.

[0038] Example 4: This example is a further limitation based on Example 1. The embedded connector 1 can not only adopt the embedded bolt structure in Example 3, but also adopt the embedded channel type 1-2. Figure 4-6 As shown, the embedded groove type 1-2 includes an embedded groove 1-2-1 and a T-bolt 1-2-2. The embedded groove 1-2-1 is embedded in the tunnel top 5. The T-head of the T-bolt 1-2-2 is adapted to the embedded groove 1-2-1. The top of the integral insulating suspension bracket 2 is provided with a mounting hole for cooperating with the T-bolt 1-2-2. The mounting hole of the integral insulating suspension bracket 2 is put on the T-bolt 1-2-2 and locked by a nut.

[0039] In this embodiment, the integral insulating suspension bracket is fixed using a pre-buried groove. Since the T-bolts in the pre-buried groove are easy to move, the position of the integral insulating suspension bracket can be adjusted easily, and the fixed connection has better flexibility.

[0040] Example 5: This example further defines Example 1. The upper portion of the busbar positioning clamp 3 is fixedly connected to the mounting hole at the lower portion of the integral insulating suspension bracket 2 via a fixing connection hole 3-2 and a fixing bolt 3-3. The lower portion of the busbar positioning clamp 3 is provided with a busbar mounting groove 3-1 that conforms to the shape of the busbar 4 to ensure the busbar is hoisted.
