JPH0524515A - Direction changing device of stopped vehicle - Google Patents

Abstract

PURPOSE:To enable insertion of a frame for direction changing and travelling on the rails by lifting a vehicle in order to realize a mode change from road- travelling to rail-travelling of the vehicle capable of both modes on a crossing. CONSTITUTION:A frame 2 which is formed by crossing a main member and two branched parallel members at right angles, is inserted to a shaft center 1a of a base plate in a rotatable manner, and a roller 3 which is rollable on the base plate is provided to the ends of the respective branched members. A lifting device (H) is erected on the respective ends of the main member, and a lifting arm 6 of inverse V letter shape which is elevated/lowered by the lifting device is fixed to a top bearing metal piece 5. An inner edge part 6a is provided to the lower end of the lifting arm, enabling coupling with the side of a vehicle.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for lifting a vehicle on a road having a limited width and changing the direction of the vehicle.

[0002]

2. Description of the Related Art There has been invented a device which is mounted on a vehicle in which both front and rear wheels have a distance between left and right tires which is close to a rail distance of a railroad to enable self-propelled operation on the rail. It consists of four frames that can be fitted into each tire.
As shown in, a raceway A for guiding the frame body along the rail,
A passive wheel B that advances the frame in response to the progress of the tire,
The auxiliary wheel C controls the direction of the tire along the rail. This road and rail vehicle is extremely useful for urgently reaching the scene in the event of a railway accident,
When traveling on the road and reaching the railroad crossing, the vehicle direction must be changed to the rail direction and the vehicle must be lifted to mount the frame. If there is no equipment that makes this possible, regardless of the distance from the accident site, first of all there is the inconvenience of having to aim for a vehicle factory equipped with a hoist and a turntable, and then change to a rail and restart.

[0003]

A device for lifting both sides of a vehicle is provided so as to face a frame that can turn on a substrate. The frame can be as long as the width of the car. The substrate only needs to support the load applied to the frame and does not require a large area. Unlike a stationary rolling stand, the entire unit is significantly smaller. It is composed of members that can be easily assembled, and is loaded on a vehicle to run on a road. Assemble at the railroad crossing near the accident site and use it to move the vehicle onto the rail.

[0004]

The target vehicle is such that the distance between the left and right tires of both the front and rear wheels is close to the distance between the rails, and the drive system may be front wheels, rear wheels or all wheels.

The drawings will be described below. The substrate 1 has a shaft core 1a protruding in the center. The frame 2 is formed by connecting a main member 2a and two branch members 2b in a square shape and is rotatably inserted into the shaft core 1a through a central hole of the main member. A roller 3 is provided which can roll over.
Lifting devices H are erected on both ends of the main material 2a. Although the lifting device is shown in FIG. 3 assuming a cylinder device using a nitrogen gas cylinder and having the receiving metal 5 on the upper end of the piston rod 4, it may be a mechanical mechanism such as a pantograph type or a pin rack type. The lifting arm 6 has an inverted V-shape and is fixed to the receiving metal fitting 5 at the central portion.
And an inward edge 6a engageable with.

[0006]

Function: The position of the board is determined so that the center hole of the board is on the center line of the left and right rails, and the board is placed on the railroad crossing. The vehicle is advanced over this so that the center of gravity of the vehicle is above the center hole of the substrate. Lifting devices are installed upright on the left and right sides of the vehicle, and lifting arms 6 are fixed to the receiving brackets 5 at the top. The lifting device lifts the vehicle and rotates the frame so that the vehicle direction matches the rail direction. Then, when lowering the vehicle, the tires are fitted into the frame (FIG. 4) described in "Prior Art". When the vehicle is moved forward as it is, the guide wheels of the frame body ride on the rails, and the vehicle is guided by the rails so that the vehicle can travel on the rails.

[0007]

[Effect] A vehicle traveling on a road and approaching a railroad crossing can be sent to a rail that intersects with the road without the need of human power by this device by assembling a carrying member.
