Description

Technical Field

[0001] This utility model relates to the field of urban rail transit catenary technology, specifically a special suspended double-line busbar for the current-taking section of a rigid catenary. Background Technology

[0002] The main functions of overhead contact line busbars include efficient and stable power transmission, safe and reliable electrical transmission, load balancing, and scalability. Overhead contact line busbar technology can achieve continuous power supply and avoid power outages. Due to its simple structure and high reliability, it can be widely used in high-speed trains, subways, urban rail transit, and highways, providing stable power supply for the transportation industry.

[0003] However, it still has some drawbacks. For example, the traditional rigid contact network design of underground railway lines uses a busbar + contact wire design for the entire line (using busbar elastic clamps in high current sections). The traction current flows to the pantograph carbon contact plate only through a single contact wire. There is generally a large amount of wear in the acceleration area when the train leaves the station. Whether it is optimizing the automatic driving mode or setting track speed limits to reduce peak traffic, the goal is to reduce the traction current of the electric train to improve the increasingly serious pantograph-catenary electrical wear problem during automatic driving. At the same time, since the busbar itself is made of rigid material, it will expand and contract with temperature changes, causing the contact wire clamped on the busbar to loosen, which will also cause wear of the pantograph-catenary electrical system.

[0004] To address the aforementioned issues, this application proposes a special suspended double-line busbar for the current-taking section of a rigid contact network. Summary of the Invention

[0005] The purpose of this utility model is to provide a special suspended double-line busbar for the current-taking section of the rigid contact network, so as to solve the problem that the existing technology mentioned in the background art generally has large wear in the train departure acceleration area. Whether it is optimizing the automatic driving mode or setting track speed limit peak driving, the problem is to improve the increasingly serious pantograph-catenary electrical wear during the automatic driving process by reducing the traction current of the electric train.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a special suspended double-line busbar for the current-taking section of a rigid contact network, comprising a busbar, a connecting plate fixedly connected to the inner surface of the upper center of the busbar, an aluminum plate disposed between the busbar and the connecting plate, a toothed boss one fixedly connected to the outer surface of one upper end of the busbar, a toothed boss two fixedly connected to the outer surface of one upper end of the connecting plate, a reinforcing component disposed on the outer surface of the upper center of the toothed boss two, a bolt passing through one side of the outer surface of the busbar, and a nut threadedly connected to the outer wall of one end of the bolt.

[0007] Preferably, the reinforcement assembly includes a positioning side plate, a sleeve, a connecting slide rod, a return spring, and a connecting circular block. The number of the sleeve, the connecting slide rod, the return spring, and the connecting circular block are all four sets. The positioning side plate is fixedly connected to the outer surface of the upper center of the tooth-shaped boss two.

[0008] Preferably, sleeves are fixedly connected to the outer surfaces of the left and right sides of the positioning side plate.

[0009] Preferably, a connecting slide rod is movably connected to one outer surface of the sleeve, and a connecting circular block is fixedly connected to the other outer surface of the connecting slide rod, and the connecting circular block is fixedly connected to the other outer surface of the tooth-shaped boss.

[0010] Preferably, a return spring is sleeved on the outer wall of the connecting slide rod, and the return spring is located between the sleeve and the connecting circular block.

[0011] Preferably, the first tooth-shaped protrusion and the second tooth-shaped protrusion are opposite each other to form a tooth-shaped clamp, and the outer surface of the center of the tooth-shaped clamp holds a contact line, and there are two sets of the first tooth-shaped protrusion, the second tooth-shaped protrusion and the contact line.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model, through the two sets of tooth-shaped protrusions, forms two sets of tooth-shaped clamps, which can facilitate the clamping of double contact wires on the busbar. By diverting the pantograph traction current, it can reduce electrical wear and solve the problem of electrical wear caused by excessive pantograph traction current. The effect is obvious, and it does not require special expertise in vehicle operation organization and automatic driving system, and the impact range is small.

[0014] This utility model, through its reinforced components, helps to reduce the possibility of loosening of the contact wires clamped on tooth-shaped boss one and tooth-shaped boss two due to environmental influences when clamping two sets of contact wires. The reset spring and connecting slide rod are designed so that the tooth-shaped clamp formed by the rigid tooth-shaped boss one and rigid tooth-shaped boss two will change with the environment (when thermal expansion and contraction occurs), preventing the contact wires clamped on the tooth-shaped clamp from loosening and causing wear of the pantograph-catenary electrical system.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-3 This utility model provides a technical solution: a special suspended double-line busbar for the current-taking section of a rigid contact network, comprising a busbar 1, a connecting plate 2 fixedly connected to the inner surface of the upper center of the busbar 1, an aluminum plate 3 disposed between the busbar 1 and the connecting plate 2, a toothed boss 4 fixedly connected to the outer surface of one upper end of the busbar 1, a toothed boss 5 fixedly connected to the outer surface of one upper end of the connecting plate 2, a reinforcing component 6 disposed on the outer surface of the upper center of the toothed boss 5, a bolt 7 passing through one side of the outer surface of the busbar 1, and a nut 8 threadedly connected to the outer wall of one end of the bolt 7, the aluminum plate 3 thereon can provide a reinforcing effect on the connecting plate 2 fixed in the middle of the busbar 1.

[0021] In this embodiment, as Figures 2-3As shown, the reinforcing component 6 includes a positioning side plate 10, a sleeve 11, a connecting slide rod 12, a return spring 13, and a connecting circular block 14. There are four sets of each of the sleeve 11, connecting slide rod 12, return spring 13, and connecting circular block 14. The positioning side plate 10 is fixedly connected to the outer surface of the upper center of the tooth-shaped boss 5. The positioning side plate 10 facilitates the installation of the tooth-shaped connecting sleeve 11 and connecting slide rod 12 on one side of the tooth-shaped boss 5. Sleeves 11 are fixedly connected to the outer surfaces of both sides of the positioning side plate 10. A connecting slide rod 12 is movably connected to one outer surface of the sleeve 11. A connecting circular block 14 is fixedly connected to the outer surface of the other end of the connecting slide rod 12, and the connecting circular block 14 is fixedly connected to the other outer surface of the tooth-shaped boss 5. A return spring 13 is sleeved on the outer wall of the slide rod 12, and the return spring 13 is located between the sleeve 11 and the connecting circular block 14. With the return spring 13, the toothed clamp formed by the rigid toothed boss 1 4 and the rigid toothed boss 2 5 will change with the environment (when thermal expansion and contraction occurs), so that the contact line 9 clamped on the toothed clamp will not loosen, causing wear of the pantograph and catenary electrical system. The toothed boss 1 4 and the toothed boss 2 5 form a toothed clamp, and the contact line 9 is clamped on the outer surface of the center of the toothed clamp. The number of toothed boss 1 4, toothed boss 2 5 and contact line 9 are two sets. With the two sets of contact lines 9, it is convenient to clamp double contact lines 9 on the busbar 1, and reduce electrical wear by diverting the pantograph and catenary traction current.

[0022] Working Principle: A special suspended double-line busbar for use in the current-taking section of a rigid contact network. In operation, the two sets of toothed protrusions 4 and 5 form two sets of toothed clamps, facilitating the clamping of the double contact wires 9 onto the busbar 1. By diverting the pantograph-catenary traction current, electrical wear is reduced, thus solving the problem of excessive current taking by the pantograph and significantly improving electrical wear. Furthermore, it requires no expertise in vehicle operation organization or automatic driving systems, and its impact range is relatively small. The reinforcement component 6 helps to reduce the possibility of loosening of the contact wires 9 clamped on the tooth-shaped boss 1 4 and tooth-shaped boss 2 5 due to environmental influences when clamping the two sets of contact wires 9. The reset spring 13 and connecting slide rod 12 can change the tooth-shaped clamp formed by the rigid tooth-shaped boss 1 4 and rigid tooth-shaped boss 2 5 with the environmental changes (when thermal expansion and contraction occur), so that the contact wires 9 clamped on the tooth-shaped clamp will not loosen and cause wear of the pantograph-catenary electrical system.

[0023] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
