Abstract

(57) [Abstract] [Purpose] To provide a safe driving by providing an abnormality detection sensor to avoid danger during running, such as a fallen tree on the rail or damage to the vehicle or the rail itself. [Constitution] Bumper mounting shafts 2 are provided so as to project from both ends of the base 1, and the bumper mounting shafts 2 are slidably mounted on the bumper 3
The spring 4 is fitted into the bumper mounting shaft 2, and the bumper 3 is held so as to always be pushed out.The limit switch 5 and the stopper shaft 6 are provided inside the bumper mounting shaft 2.
By pressing the limit switch 5 on the inner surface of the bumper 3, an electric circuit is activated to stop the drive of the transporter and apply a brake. [Effect] By providing the abnormality detection sensor, it is possible to detect a fallen tree on the rail, damage to the vehicle or the rail itself, and stop the transporter, thereby avoiding danger and enabling safe driving.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This plan relates to a transporter for personnel transport, which has been developed from the single-rail transporter for agriculture used to transport fruits, fertilizers, chemicals, etc., installed on steep slopes such as orchards, and particularly transporters. It is related to the anomaly detection sensor installed in the bumper before and after.

[0002]

[Prior art]

 Conventionally, a dangerous state during running, such as a fallen tree on the rail or damage to the vehicle or the rail itself, depends on the driver's visual inspection, and the driver who has judged an abnormality performs a stop operation. .

[0003]

[Problems to be solved by the device]

 Therefore, it was difficult to make a visual judgment at dusk or when fog occurred, and a dangerous situation was seen. Moreover, even if a fallen tree on the rail or a preceding vehicle could be found, damage to the rail itself was difficult to find. Therefore, the purpose of this plan is to detect the abnormality on the rail and the abnormality of the rail itself by a machine without relying on the visual observation of the driver, and avoid the danger even at dusk or when fog occurs to drive safely. It is a thing.

[0004]

[Means for Solving the Problems]

 In this plan, a bumper 3 is installed at the front of the vehicle of the carrier, and the limit switch 5 is activated by the movement of this bumper 3 to detect foreign matter on the rail, and the rail is running abnormally due to twisting of the rail. It detects the inertial force of the motor, stops the drive, and operates the brake.

[0005]

【Example】

 An example of this plan will be described in detail.In the construction of a transmission line, in a single-rail transport machine laid from the village side to the mountain side for commuting, a base 1 is installed in front of and behind the carrier, and both ends of this base 1 are installed. A protruding bumper mounting shaft 2 with a screw at the tip, a bumper 3 is slidably mounted on the bumper mounting shaft 2, and a spring 4 is inserted into the bumper mounting shaft 2 and the spring 4 The bumper 3 is pushed out at all times by being urged and held by a nut.The limit switch 5 is attached to the inside of the bumper mounting shaft 2 that protrudes from the base 1, and the limit switch 5 is attached to the hole provided in the base 1. Attach the shaft 6 and press the limit switch 5 on the inner surface of the bumper 3 to activate the electric circuit, operate the electromagnetic valve in the hydraulic circuit of the drive system of the transporter, stop the hydraulic pressure and stop the rotation of the hydraulic motor. What to do The brake built into the hydraulic motor works, and the pinion of the drive wheel meshes with the rail rack, so an abnormality detection sensor that can be stopped without slip of the transport machine is provided in front of and behind the transport machine.

The operation of the abnormality detection sensor of the embodiment of the present invention is such that if the bumper 3 comes into contact with a fallen tree on the rail or the transporting vehicle traveling ahead is stopped at a curve, the bumper 3 is pushed and the limit is reached. You can press switch 5 to activate the electric circuit, stop the drive of the transporter, and apply the brakes. The other operation is that when the transporter is running at a constant speed, the resistance increases due to rail damage (twisting) and the speed of the transporter drops, causing the bumper to recoil due to the reaction of inertial force. 3 moves against the spring 4 and pushes the limit switch 5, which also activates the electric circuit, which can stop the drive of the transport machine and apply the brakes.

[0007]

[Effect of device]

 Even when the visibility is poor at dusk or when fog occurs, the plan can detect a fallen tree on the rail or damage (twist) on the vehicle or the rail itself to stop the transport machine and avoid the danger. Also, unlike the conventional method that relies on the driver's visual observation, the driver's fatigue can be reduced. In addition, rail maintenance can be performed by detecting damage (twist) on the rail itself and checking or replacing the rail where the transporter stopped. If only the rails at the same location are damaged, it may be possible to change the laying route, and it is possible to select a safer route and drive safely.
