Abstract

(57) [Summary] [Purpose] To prevent the derailment and fall of construction vehicles and transport equipment when laying a single rail. [Structure] Projecting arm 3 at the tip of the trolley for construction vehicles and transporters
A guide roller 6 that travels on the rail is provided at the tip of the protruding arm 3, and a limit switch 5 provided below the protruding arm 3 when the guide roller 6 derails and falls.
Is operated to shut off the drive system engine or generator circuit to emergency stop the drive wheels. [Effect] The projecting arm 3 projecting from the tip of the bogie can detect the abnormality on the rail or the end of the rail quickly, stop the construction vehicle or the transporter in an emergency, and prevent derailment from the rail. By the way, it is possible to transport the personnel safely.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present application relates to a single-rail carrier, and more particularly to a configuration designed to prevent the rollover of a bogie from the rail end when the rail is laid or when a natural disaster such as landslide occurs.

[0002]

[Prior art and problems]

 The conventional method of laying rails for a single rail carrier is to run a truck for material transportation on the finished rail, transport rails, stanchions, etc., and move forward. In such a construction method, a dolly loaded with materials is unmanned from a material storage area on the road, and stopped at the construction site to unload the materials. Although it is possible to recognize the approach of the trolley by the engine sound, it is desirable to stop the trolley at the rail end where the construction is completed in order to shorten the transportation distance for heavy objects as much as possible, and stop operation until the last minute. It was not there. As a result, there were cases where the wheels fell from the rail ends and the entire trolley fell. Derailment and capsizing of a truck full of rails not only endangers people under construction, but if the drive truck and the truck were disconnected, the truck could run away and crash into the material storage area. . In addition, when a railroad is cut due to landslides, flash floods, etc., a dangerous state occurs as well, and a particularly effective safety device for a transport machine for transporting personnel has been desired.

[Means for solving problems]

 In order to prevent the single rail carrier from being stripped from the rail end, it is the logical reason to sense the end of the rail and stop the driving force and apply the braking force. If the guide roller moving on the rail at the tip of the arm falls below the rail end, the limit switch will work to shut off the drive system circuit.

【Example】

 To describe the embodiment of the present application, the base 2 is attached to the tip of the earliest carriage 1, the base end of the protruding arm 3 is attached to the top end of the base so as to be vertically and horizontally rotatable, and the bottom end is also attached. The limit switch 5 is provided so as to project to keep a predetermined distance from the projecting arm 3. At the tip of the protruding arm 3, a guide roller 6 mounted on a rail 8 is provided, and a holding plate 7 is provided at a position corresponding to the limit switch 5. The limit switch 5 is linked to the electric circuit of the engine, and is configured to shut off the circuit when pushed down by an external force. When the guide roller 6 of the protruding arm 3 is placed on the rail 8 for traveling and the stopping operation is not performed despite the rail end, the protruding arm 3 falls off from the end of the rail 8 and the holding plate 7 reaches the limit. The switch 5 is pushed down, the electric system of the engine is cut off, and the transporter is stopped. When the engine is stopped, the attached electromagnetic brake operates and maintains the stopped state even on sloping ground.

[Effect of device]

 As described above, by using the present invention, it is possible to prevent the rolling overturning of the bogie from the rail end during the construction of a single rail or when a natural disaster occurs regardless of the driving operation.
