Description

Technical Field

[0001] The utility model belongs to the field of electrified overhead contact lines, and more specifically, relates to a support device for an electrified overhead contact line. Background Art

[0002] When the existing overhead contact line comes into contact with the top surface slide plate of the pantograph, due to the fixed connection of the overhead contact line itself and the lack of elasticity, when the top surface slide plate of the pantograph slides and draws current in friction with the overhead contact line, there will be an interruption in current collection, and the overhead contact line cannot fully fit the top surface slide plate of the pantograph; there is a lack of further locking for the wire clamp structure of the overhead contact line. Especially when the top surface of the pantograph frictional contacts the overhead contact line, the overhead contact line shakes, greatly increasing the risk of falling off.

[0003] Chinese Patent with Publication No. CN220535469U discloses a support device for an electrified railway overhead contact line, including a support column, a flat cross arm, and an inclined cross arm. The flat cross arm and the inclined cross arm are fixed to the side of the support column through an installation component. The installation component includes a clamping plate A and a clamping plate B, and the clamping plate A and the clamping plate B are arranged on both sides of the support column. A mounting groove is opened in the middle of the top of the clamping plate A, and a vertical groove adapted to the mounting groove is opened on one side of the clamping plate A. Positioning plates integrally formed with the flat cross arm and the inclined cross arm are fixed at the ends of the flat cross arm and the inclined cross arm. In this support device for the electrified railway overhead contact line, the force-bearing members at the connection between the flat cross arm and the inclined cross arm and the support column are not only bolts, but also the inner wall of the mounting groove limits and supports the positioning plate integrated with the flat cross arm and the inclined cross arm, thereby improving the support effect and avoiding the situation that the fasteners of the flat cross arm, the inclined cross arm and the fixed support column are prone to looseness due to the long-term bearing of the angular force, affecting the stability and firmness of the support.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0029] An application of one aspect of this embodiment is: according to the different force conditions caused by the distribution density of each buffer assembly 6, turn the screw rod 652, so that the adjusting plate 653 threadedly connected to its surface moves and squeezes the spring 66, changing the elastic force and stroke of the spring 66.

[0031] As Figure 4 shown, a support diagonal rod 8 is fixedly connected to the bottom surface of the horizontal tie rod 3 of this embodiment, the bottom end of the support diagonal rod 8 is fixedly connected to the boom 4, and a number of openings for weight reduction are successively opened on the side of the support frame 1 from top to bottom; the support diagonal rod 8 can increase the firmness between the horizontal tie rod 3 and the boom 4 and prevent shaking caused by the influence of air flow, resulting in the catenary shaking accordingly and affecting the current collection effect of the pantograph.

[0032] Embodiment 1:

[0033] In this embodiment, the buffer assembly 6 includes a top plate 61 fixedly connected to the bottom surface of the connection block 5. The bottom surface of the top plate 61 is symmetrically provided with an upper arc plate 62. The side of the upper arc plate 62 is slidably connected with a lower arc plate 63.

[0034] After the catenary is installed inside the wire clamp assembly 7, the self-weight of the catenary drives the bottom plate 64 to move downward. While the bottom plate 64 moves downward, the spring 66 is pulled. When the sliding plate of the pantograph on the top surface of the train contacts the catenary, the spring 66 rebounds and stretches to keep the catenary below always in contact with the sliding plate of the pantograph on the top surface of the train. At the same time, according to the different force conditions caused by the distribution density of each buffer assembly 6, the screw rod 652 is rotated, so that the adjusting plate 653 threadedly connected to its surface moves and presses the spring 66, changing the elastic force and stroke of the spring 66, thereby achieving the effect of keeping the catenary always fully in contact with the sliding plate on the top surface of the pantograph and avoiding intermittent situations during current collection.

[0037] After the catenary is clamped inside the wire clamp 71, the screwing rod 72 is rotated to move it inside the threaded hole on the side surface of the wire clamp 71, driving the small bearing 73 sleeved at one end to move accordingly. The clamping plate 74 fixed to the side surface of the small bearing 73 protrudes from the groove on the side surface of the wire clamp 71 to further squeeze and fix the catenary clamped inside the wire clamp 71, improving the installation firmness of the catenary, thereby achieving the effect of preventing the sliding plate on the top surface of the pantograph from sliding and rubbing against the catenary and the catenary from shaking and loosening and falling off.
