Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a support device for a current collector that slides in contact with the inner peripheral surface of a duct type trolley wire.

[Conventional technology]

A duct-guided current collector device collects current by sliding the current collector on the inner circumferential surface of a duct-type trolley wire. It is configured to slide in contact with the inner peripheral surface of the trolley wire to collect current.

[Problem that the invention seeks to solve]

In the conventional duct-guided current collector as described above, there is a gap between the running current collector and the duct-type trolley wire in the vertical and horizontal directions, depending on the manufacturing accuracy of the ducted trolley wire and the quality of the installation work and the installation work of the vehicle running track. If misalignment occurs, the current collector will not be able to make complete contact with the trolley wire, causing noise and radio interference. To prevent this, a coil spring is used to move the current collector freely relative to the trolley wire. However, this requires a large number of coil springs of various sizes and strengths to respond to vertical and horizontal rocking, making the support device complex and large, making it easy to break and prevent high-speed running. The problem was that it was not suitable for a current collector.

Therefore, the present invention can stably hold the support mechanism of the collector, does not make the support device complicated and large, and allows the collector to stably and smoothly follow the trolley wire in the vertical and horizontal directions. The object of the present invention is to provide a current collector support device for a duct type trolley wire that can prevent twisting of the trolley wire.

[Means for solving problems]

In order to solve the above-mentioned problems, the current collector support device for a duct type trolley wire of the present invention includes a current collector 2 that slides in contact with the inner peripheral surface of a duct type trolley wire 1 having an arcuate cross section and an inverted gutter shape. The current collector support rod 3 is supported at the upper end of the current collector support rod 3, and the current collector support rod 3 is erected at the tips of two parallel movable arms 4, 4 extending at right angles to the trolley wire direction. Both ends of a common shaft 6 are installed between the rear parts of the movable arms 4, two square blocks 5, 5 are loosely fitted onto the common shaft 6, and the fixed guides 7, 7 extending parallel to the movable arms 4, 4 are covered with a protective case. The top surface of the bottom plate 8a and the top cover 8
b Mounted on the lower surface, the two square blocks are sandwiched from above and below by the upper and lower fixed guides 7, 7, and the square blocks are fitted and held in the grooves 7a of the fixed guides, and one end is fixed to the protective case 8. The movable arms 4, 4 are elastically held in the vertical direction by a spring 9, and the springs 10, 11, one end of which is fixed to the protective case 8, elastically hold the movable arms 4, 4 in the horizontal direction. The protective case 8 is attached to a traveling vehicle 14 with an insulator 13.

[Effect]

The collector 2 moves the movable arms 4 in the vertical direction when the vehicle 14 moves and slides in contact with the reverse gutter-shaped inner peripheral surface of the duct type trolley wire 1 having an arcuate cross section. The trolley wire runs while elastically contacting the inner circumferential surface due to the elasticity of the spring 9 that is elastically held therein.

Common shaft 6 to which the movable arm 4 is attached
The movable arm 4 is stably held because the rectangular block 5 into which it is loosely fitted is fitted into the grooves 7a of the fixed guides 7, 7 and held between the upper and lower sides.

When the collector 2 travels along the trolley wire 1, if the collector 2 moves up and down in accordance with the vertical change in the installation state of the trolley wire 1, it loosely fits into the rectangular blocks 5, 5. The movable arms 4, 4 supported by the common shaft 6 swing vertically with the common shaft 6 as a fulcrum, so that the collector 2 responds to the vertical movement of the installation position of the trolley wire 1. Runs while freely following movement.

In addition, when the current collector 2 moves in the left-right direction according to changes in the installation state of the trolley wire 1, the square blocks 5, 5, into which the common shaft 6 supporting the movable arms 4, 4 is loosely fitted, By sliding in the left-right direction in the groove 7a between the upper and lower fixed guides 7, 7, the collector 2 freely follows the movement of the trolley wire installation position in the left-right direction.

Furthermore, when the current collector 2 is torsionally displaced in the direction of the trolley wire, since the rectangular block 5 is fitted into the groove 7a of the fixed guide 7, the torsion of the rectangular block 5 is regulated by the groove 7a. This restricts the twisting of the current collector 2.

Furthermore, when the sliding surface of the rectangular block 5 that slides in contact with the groove 7a of the fixed guide 7 is worn out,
By turning the rectangular block 5 90 degrees and refitting it into the groove 7a, it can be used for a long period of time.

〔Effect of the invention〕

In the current collector support device for a ducted trolley wire of the present invention configured as described above, the current collector 2 runs in contact with and slides on the inner circumferential surface of the ducted trolley wire 1 which is in the form of a reverse gutter and has an arcuate cross section. A common shaft 6 with a movable arm 4 that supports the current collector 2 is loosely fitted into the rectangular block 5. Since the movable arm 4 is sandwiched between the fixed guides 7, 7 from both the upper and lower sides, the movable arm 4 can be stably held.

When the collector 2 moves up and down in accordance with the vertical change in the installation state of the trolley wire 1, the movable arm 4 follows and swings up and down using the common shaft 6 as a fulcrum, and when the collector 2 moves in the horizontal direction, Since the rectangular block 5 can slide left and right between the upper and lower fixed guides 7, the current collector 2 can be moved either up or down or left or right depending on the change in the installation state of the trolley wire 1. Since the current collector 2 can be freely tracked and the current collector 2 can be prevented from twisting, not only can good electrical contact between the current collector and the trolley wire be always obtained, but also forced contact between the trolley wire and the current collector can be avoided. Since this does not occur, it is possible to reduce wear.

Further, even if the square block 5 is worn out, it can be used for a long period of time.

In addition, the number of component parts is small and the entire device is small and robust, making it ideal as a support device for current collectors of duct type trolley wires running at high speed.
