Technical Field

[0001] This invention belongs to the field of electrified railway power supply systems, and particularly relates to an electrified railway suspension system. Background Technology

[0002] The function of the electrified railway suspension system is to provide power to electric locomotives. Currently, it can be divided into flexible suspension systems and rigid suspension systems. Flexible suspension systems are usually used for lines with large outdoor clearance, while rigid suspension systems are usually used for lines with small clearance, such as subways and tunnels. Rigid suspension systems have a compact structure and are suitable for use in tunnels.

[0003] The main problems in the application of suspension systems in electrified railways include: compared with electric locomotives using flexible suspension systems, electric locomotives using rigid suspension systems have a narrow speed adaptability, large errors in conductor height and pull-out value, substandard overall busbar smoothness, and are prone to excessive hard points; sagging at intermediate joints, contact wire detachment, severe contact wire wear, stuck or inflexible positioning clamps with no adjustment margin, sagging at busbar joints forming hard points, significant contact wire wear, prominent issues such as rigid-flexible transition, expansion joints, arcing of segmented insulators, and severe ablation.

[0004] To avoid the aforementioned technical problems, it is indeed necessary to provide an electrified railway suspension system to overcome the deficiencies in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide an electrified railway suspension system that addresses the problems of rigid suspension systems in electric locomotives, such as narrow speed adaptability, large errors in guide height and pull-out values, substandard overall busbar smoothness, and excessive hard points.

[0006] This invention is implemented as follows: an electrified railway suspension system includes a busbar, said busbar being made of aluminum alloy, and further includes:

[0007] A guide rod is provided, and an elastic mechanism is provided between the guide rod and the busbar, the elastic mechanism being used to provide elastic support for the guide rod;

[0008] The guide rod is connected to a contact wire clamp rod, and an adjusting component is provided between the guide rod and the contact wire clamp rod. The adjusting component can adjust the distance between the guide rod and the contact wire clamp rod.

[0009] The contact wire clamp is connected to a fixing mechanism, and the fixing mechanism is fixedly connected to the contact wire.

[0010] A guide line connects the busbar to the fixed mechanism.

[0011] In a further technical solution, the elastic mechanism includes a lower spring seat, a lower spring, and an anti-collision component;

[0012] The inner wall of the busbar is provided with a step, the lower spring seat is placed on the step of the inner wall of the busbar, the lower spring seat is provided with a through hole, the guide rod passes through the through hole of the lower spring seat, the anti-collision component is fixedly connected to the guide rod, the anti-collision component is used to prevent the guide rod from colliding with the inner top surface of the busbar, the lower spring is sleeved on the outside of the guide rod, and the lower spring is disposed between the lower spring seat and the anti-collision component.

[0013] In a further technical solution, the anti-collision component includes an upper spring and a spring seat, wherein the spring seat is fixedly connected to the guide rod, and the upper spring is fixedly connected to the spring seat.

[0014] In a further technical solution, the fixing mechanism includes an anti-loosening nut, a contact clamp, and a bolt;

[0015] The contact clamp is connected to the contact clamp rod, the bolt passes through the contact clamp, and the bolt is threaded with an anti-loosening nut. The contact clamp holds and fixes the contact wire, and the guide wire is connected between the busbar and the contact clamp.

[0016] In a further technical solution, the adjusting component is an adjusting sleeve, which has two threads in opposite directions inside, and the two threads are respectively threaded to the guide rod and the contact line clamp rod.

[0017] In a further technical solution, the contact clamp is U-shaped.

[0018] In a further technical solution, both the upper and lower spring seats are provided with bosses, and the bosses are provided with parallel sides facing each other, with the parallel sides on both sides of the bosses connected by arc-shaped edges.

[0019] A further technical solution is that one end of the guide line is connected to the busbar, and the other end of the guide line is connected to the contact clamp via a positioning bolt.

[0020] In a further technical solution, a wear-resistant sleeve is provided between the guide rod and the lower spring seat, and the wear-resistant sleeve and the guide rod are installed with a clearance fit.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The present invention provides an electrified railway suspension system in which, when the pantograph is not in contact with the contact wire, the entire system, except for the busbar and the lower spring seat, is borne by the lower spring and is in a balanced state; when the pantograph makes contact, the upward force of the pantograph causes the contact wire and the entire system (except for the busbar) to rise, thus achieving system flexibility; the function of the upper spring is to provide a downward pressure to the system when it is raised too high, so as not to collide hard with the top of the busbar.

[0023] This invention provides an electrified railway suspension system in which the contact wire is clamped by a U-shaped contact wire clamp. The contact wire clamp is the same length as the contact wire and is bolted together to provide clamping force, maintain the smoothness of the contact wire, and provide current conduction. The contact wire clamp rod is fixed to the contact wire clamp, and the guide rod is connected to the upper spring seat to transmit the weight of the lower suspension part to the lower spring, which bears the weight and achieves balance. The function of the lower spring seat is to bear the force of the lower spring. The lower spring seat is placed on a platform inside the busbar so that the force of the suspension part is transmitted to the busbar. The rectangular structure at the bottom of the lower spring seat plays a guiding role. The upper spring is not normally under force. Only when the contact wire is raised too much, the upper spring contacts the top of the busbar and provides a downward pressure to prevent the upper spring seat from colliding hard with the top of the busbar.
