Description

Description: TECHNICAL FIELD The present invention relates to a pantograph support device for a railway vehicle with a vehicle body tilting device, and when the vehicle body is tilted in a curve inward, the pantograph is displaced relative to the overhead line. As a result, it is possible to optimally set the height of the center of rotation of the vehicle body tilt and the vehicle body tilt angle of the vehicle equipped with the vehicle body tilt device, It is possible to provide a railway vehicle equipped with a vehicle body tilting device having good comfort and less movement of the vehicle body weight center.

(Prior Art) An example of a conventional vehicle pantograph support device will be described with reference to FIG. FIG. 4 is a front view of a conventional pantograph moving device. In the figure, the pantograph 1 is supported by a link 18, and an air cylinder 20 that operates according to the output of a control device 19 that outputs curve information operates the link.
The pantograph was forcibly moved in the direction opposite to the direction in which the vehicle body 2 was inclined during curve running. In this method, the link cannot be made too large due to the limitations of the vehicle, so the required amount of relative movement between the vehicle and the overhead line in the left-right direction cannot be sufficiently secured, or if the control fails, the pantograph However, there is a problem that there is a risk of breaking the overhead line.

(Problems to be Solved by the Invention) As a method for solving the above-mentioned problems of the pantograph supporting device for a vehicle, the pantograph is supported by a pantograph rotating support that can be turned on a roof of a vehicle body, and the pantograph rotating support is provided. Mechanically restrained from the bogie frame that is not related to the vehicle body inclination, always rotate the pantograph current collector boat in the opposite direction to the body inclination direction, and the relative movement amount of the pantograph and the overhead line during the curve running in the left and right direction And at the same time, a mechanically reliable system that does not rely on a control system that could fail.

(Means for Solving the Problems) A single-armed pantograph formed in a "-" shape with a link is supported by a pantograph rotation support base that turns on the roof of the vehicle body, and the turning direction is opposite to the inclination of the vehicle body. The current collection boat is always positioned on a vertical line to the center of the track, and as a means of maintaining the neutral position, a pair of left and right sides of the right and left sides of the bogie that are not related to the body tilting operation are always equal in length. The mechanism is restrained by a steel rope. Further, a guide pulley for passing the steel rope from the left and right side beams of the bogie frame to the pantograph support base on the body roof through the vehicle body side, or gears, pulleys and the like and up and down of the air spring. Steel rope, or chain, due to left and right deflection of the vehicle body, or chain, in order to prevent excessive tension or deflection in the belt, etc., the steel rope, or chain,
A tension applying device that applies a constant tension to a belt or the like that does not impair the vibration isolation performance of the air spring is provided.

(Embodiment) The first embodiment of the pantograph supporting device according to the present invention will be described.
This will be described with reference to FIG. 2, FIG. 2 and FIG. FIG. 1 is a block diagram of the entire pantograph support device of the present invention, and FIG.
The figure is a plan view of the pantograph rotary support base, the support base, and the tension applying mechanism on the vehicle body roof as viewed from above, and FIG. 3 is a side view thereof. In FIG. 1, the same reference numerals as those of the conventional example denote the same members. In the embodiment shown in FIG. 1, on the roof of the vehicle body 2, there is provided a pantograph rotation support base 4 which supports and turns a single-arm pantograph formed in a "-" shape with links. The swivel positioning of the pantograph rotary support is performed by a non-extendable steel rope 9 that passes through the vehicle body from the slide receiver of the pantograph rotary support and the left and right side beams of the bogie frame 8 to the roof, or a chain. The link 5 connects the drums 3 that take up a belt or the like. That is, the drum 3 is formed by winding a steel rope or the like drawn from the right and left side beams to the roof so that the lengths are equal in the same direction, so that the drum 3 is always on the center line 17 which is perpendicular to the track center. It is located on the same straight line as the overhead wire 15 and, based on this point, the pantograph rotation support base, which moves in the left-right direction in FIG. By rotating the single-arm pantograph supported by the table in the direction opposite to the vehicle body inclination, the relative displacement between the current collector boat and the overhead wire 15 can be reduced. Also, steel rope, or
The drum 3 that holds a point on the vehicle body center line 16 before the vehicle body leans, that is, a neutral position on a vertical line 17 erected at the track center by winding the chain and belt in the same direction.
Are supported from the support base 6 via a bearing 10.

Further, a tension applying spring 13 is attached to the lower surface of the support base, and the other end of the tension applying spring is connected to a steel rope 9 or a steel rope or a chain or a drum 3 for winding a belt.
Wrap in the opposite direction to the chain and belt winding direction,
It is a mechanism that applies a certain tension to a steel rope, chain, or belt. The constant tension applying device prevents the steel rope, the chain, the belt, and the like from being excessively tensioned or bent due to the vertical and horizontal movements of the vehicle body supported by the air spring. Incidentally, the support frame 6 of the drum can be smoothly moved in the left-right direction in FIG. 1 with respect to the vehicle body roof by the guide 7 mounted on the roof frame and the slider 12 mounted on the support frame. Therefore, the drum 3 can always maintain the neutral position. In addition, a pulley 11, a gear, or a pulley is provided to guide the steel rope 9, a chain, a belt, or the like from the vehicle body 2 on a penetrating portion of the vehicle body or on a roof.

The pantograph supporting device turns the pantograph in a direction opposite to the tilt direction of the vehicle body to reduce the relative movement amount between the current collector boat and the overhead wire. By appropriately selecting the sliding receiver, the drum 3 and the horizontal distances L1, L2 between the drum 3 and the current collector 14, the relative displacement between the pantograph current collector and the overhead wire can be further reduced.

(Effect of the Invention) Since the pantograph and the pantograph supporting device of the present invention can reduce the relative movement between the pantograph and the overhead wire, current can be safely collected from the overhead wire when traveling on a curve. Further, by adopting a mechanical structure using such a rope, the risk of fail-out in the electric control system can be eliminated, and the device can be further reduced in weight and cost.
