Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railway tunnel equipment, and more specifically to a rigid contact network busbar joint supporting device. Background Art
[0002] One of the core components of the rigid contact network in the subway tunnel section is the busbar, which is responsible for transmitting electrical energy from the power supply equipment to the contact wire, thereby providing power for the subway trains. The design and performance of the busbar are directly related to the stability and reliability of the contact network, and are of vital importance to ensuring the safety and efficiency of subway train operation.
[0003] At present, most of the buses used on subway lines are ordinary types. Although some of them are designed with reinforcement ribs to improve their stability and conductivity, their overall use scope is still small. With the external force of long-term irregular vibration of trains, the tightening bolts of the middle joints of the busbars may become loose, causing the conductor to fall, and then forming hard points on the contact network, affecting the smooth passage of the pantograph.
[0004] The problem of conductor height drop not only affects the safe operation of subway trains, but also increases the difficulty and cost of maintenance. Due to the lack of a reliable and economical method to effectively maintain the conductor height, once a problem occurs, frequent inspections and adjustments are required, which not only increases operating costs but also may cause waste of resources. At present, there is no mature technical solution for the treatment of conductor height drop of busbar intermediate joints.
[0005] Since the ordinary busbars on the current lines have not yet reached the replacement cycle, and the busbars with reinforced ribs are expensive and cannot be replaced on a large scale, this situation requires subway operators to make a trade-off between cost control and operational efficiency when facing busbar problems, and seek economical and effective solutions.

DETAILED DESCRIPTION
[0035] In order to make the purpose, technical scheme and advantages of the implementation of this application clearer, the technical scheme in the embodiment of this application will be described in more detail below in conjunction with the drawings in the embodiment of this application. In the drawings, the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions. The described embodiments are part of the embodiments of this application, not all of them. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain this application, and should not be construed as limitations on this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0036] Figure 1 This is a structural schematic diagram of a rigid contact network busbar joint support device according to an embodiment of the utility model. Figure 2The following is a schematic diagram of an application of a rigid contact network busbar joint support device according to an embodiment of the utility model. The rigid contact network busbar joint support device comprises a left busbar section 110 and a right busbar section 120. The rigid contact network busbar joint support device further comprises:
[0037] A busbar support assembly 200, wherein the busbar support assembly 200 is disposed above the left busbar section 110 and the right busbar section 120;
[0038] A fixing assembly 300, which is disposed at both ends of the busbar support assembly 200 and is fixedly connected to the busbar;
[0039] The height-maintaining and adjusting component 400 is connected to the fixing component 300 and the bus bar.
[0040] In one embodiment, the busbar support assembly 200 includes a crossbeam 210 and a support assembly 220;
[0041] The crossbeam 210 spans across the middle joint of the busbar;
[0042] The supporting assembly 220 is disposed in the middle of the beam 210 .
[0043] Specifically, the main function of the crossbeam 210 is to balance the height of the front and rear busbars. In practical applications, there may be a slight height difference between the front and rear busbars due to installation, manufacturing or other factors. Although these differences seem insignificant, they may have an adverse effect on the stability and conductivity of the intermediate joint in a high voltage and high current environment. The introduction of the crossbeam 210 ensures the height consistency of the two sides of the intermediate joint through its spanning structure, thereby stabilizing the conductive height of the intermediate joint. In addition, the crossbeam 210 also helps to improve the mechanical stability of the entire system. It can connect the front and rear busbars together to form a more stable structure. This not only prevents the busbar from shifting due to vibration or other external factors, but also reduces the risk of deformation or damage to the intermediate joint due to uneven force. And from the perspective of safety, the design of the crossbeam 210 also has its unique significance. In extreme cases, such as short circuit or overload, the crossbeam 210 can provide additional support and protection to reduce the possibility of damage to the intermediate joint and busbar. This helps to maintain the stability and reliability of the entire power system and reduce the risk of failure.
[0044] Furthermore, the supporting assembly 220 is used to fix the beam 210 .
[0045] In one embodiment, the fixing assembly 300 includes a wire clamp, which is disposed at both ends of the crossbeam 210 and fixedly connected to the left bus section 110 and the right bus section 120 .
[0046] Specifically, wire clamps are usually designed to be easy to install and remove, without the need for complex tools or techniques. In addition, wire clamps allow wires or cables to be flexibly adjusted in different positions and directions to meet various application requirements. Secondly, wire clamps can provide good electrical connections, reduce resistance and voltage drop between wires or cables, and thus improve the efficiency and reliability of electrical systems. In addition, many wire clamps also have protective functions, such as waterproof and dustproof, which can protect wires or cables from damage by the external environment. And wire clamps can compactly fix and arrange wires or cables, reducing the space occupied. In addition, wire clamps usually have lower costs because they do not require additional materials or labor. Finally, since wire clamps are easy to install and remove, they can be more conveniently added, removed or replaced when performing maintenance and upgrades on electrical systems.
[0047] The conductor height maintaining and adjusting assembly 400 includes a first bolt, and the first bolt passes through the wire clamp and is fixedly connected to the bus bar;
[0048] The first bolt is configured with a first flat washer and a first anti-loosening nut.
[0049] Specifically, the bolt connection has extremely high strength and stability, can effectively resist external stress and vibration, and ensure that the connection between the wire clamp and the bus is stable and reliable, and is not easy to loosen or fall off. Moreover, the bolt connection can adjust the positional relationship between the wire clamp and the bus by tightening or loosening the bolts, which is convenient for installation, commissioning and maintenance. At the same time, it is also very convenient to replace damaged parts, and you only need to loosen the bolts to replace them. Finally, the bolt connection has good electrical conductivity, which can effectively prevent the current from generating sparks or short circuits through the connection, ensuring the safe operation of the equipment.
[0050] Furthermore, do not over-tighten or over-loosen the bolts at one time, but adjust them gradually to ensure the pressure is appropriate.
[0051] In one embodiment, the first bolt has a diameter of 10 mm and a length of 120 mm;
[0052] The first flat pad has a diameter of 10 mm and a length of 2 mm;
[0053] The first nut has a diameter of 10 mm.
[0054] In one embodiment, the support assembly 220 includes a second bolt, and the second bolt passes through the support assembly 220 and is fixedly connected to the busbar.
[0055] In one embodiment, the second bolt is configured with a second flat washer and a second nut.
[0056] In one embodiment, the second bolt has a diameter of 12 mm and a length of 60 mm;
[0057] The second flat pad has a diameter of 12 mm and a length of 2 mm;
[0058] The second nut has a diameter of 12 mm.
[0059] In one embodiment, the middle portion of the beam 210 is higher than the busbar.
[0060] In one embodiment, a busbar support assembly 200 includes two cross beams 210 , and a support assembly 220 is fixedly connected to the two cross beams 210 .
[0061] Specifically, two crossbeams 210 are used to cross the middle joint to balance the height of the front and rear busbars, so as to stabilize the height of the middle joint. The wire clamps on both sides of the crossbeam 210 fix the front and rear busbars. By adjusting the bolts in the middle of the wire clamps, pressure is provided to maintain the height of the middle joint.
[0062] The utility model has the following beneficial effects:
[0063] 1. Mechanical brake: This device significantly reduces the collision between wear testers and effectively avoids damage by optimizing the station configuration. At the same time, this design can firmly clamp the contact line and significantly improve the safety factor during use.
