[Problems to be Solved by the Invention]

However, although a tunnel for laying cables for telephone / telephony is sometimes installed in the city, it is sufficient for the maintenance management to be large enough for people to pass through, so it is not possible to excavate a large tunnel. Absent. Therefore, in the conventional 2t class storage battery locomotive, it is not possible to make it larger than the current size, total length 2620mm, and keep the current size (without changing the size) and take safety measures. There must be. However, in the conventional 2t class storage battery locomotive,
The storage battery box is large compared to the size of the chassis, and it is not possible to secure a space for mounting a device for implementing safety measures on the chassis in addition to mounting a storage battery, and actually implementing safety measures. However, there is a problem in that a device for this purpose cannot be mounted. Therefore, in the conventional 2t storage battery locomotive, the locomotive will malfunction due to malfunction even if a person does not operate the vehicle while the locomotive is stopped while the power is on. There is a problem in that it may start moving and it is dangerous. Furthermore, in the conventional 2t storage battery locomotive, if the speed is gradually increased by driving operation, the speed will increase to the limit of the motor driving force and the safe speed will be exceeded without increasing the speed command value to the maximum. However, in this case, the speed suddenly rises to an unexpected speed, and it takes time to deal with the problem, resulting in a lack of work safety. Further, in the conventional 2t storage battery locomotive, since the manual brake is used, there is a problem that the stop operation cannot be performed in time in an emergency and it is difficult to stop at a fixed position. Therefore, a power brake may be used, and in the case of a power brake, it is advantageous to use an air cylinder to form an air brake in order to reduce power consumption. However, when using a power brake using this air cylinder, in order to stop in a short time, it is necessary to press the air cylinder to increase the frictional force between the wheel and the brake,
The air supplied to the air cylinder must be of high pressure. Moreover, if the air is supplied directly from the compressor to the air cylinder, the air pressure will be insufficient and the air will be driven by the compressor every time the compressor is driven. Pulsation occurs and the air brake cannot work smoothly. Therefore, it is necessary to install a receiver tank to remove this pulsation. However, as mentioned above,
In the conventional 2t storage battery locomotive, there is no space to mount a device for safety measures, and it is impossible to install devices such as compressor motor, compressor, receiver tank used for these power brakes. Have An object of the present invention is to miniaturize a storage battery box without changing the power capacity without changing the size of a standardized 2t storage battery locomotive, and to mount a power brake to ensure 2t in an emergency.
The storage battery locomotive is stopped so that the locomotive does not move due to a malfunction when a person is not on board, and even if the driver increases the speed, it prevents the speed from further increasing when it reaches a safe speed. However, it is to try to ensure the safety of locomotive driving.

[Means for solving problems]

In order to achieve the above object, in a 2t storage battery locomotive according to the present invention, a 160mm that supplies electric power to a motor having a traction force to pull a 630kg Zuritro to a chassis with a total length of about 2.6m.

In a 2t storage battery locomotive with a standardized full length and width that runs by pulling Zuritro on a rail laid in a tunnel with a diameter of around 2.5m by wheels that are fixed to the supported axle, The battery cells constituting the battery are arranged horizontally without changing the number of stages and are configured without changing the power capacity, and an outlet provided on the side wall of the housing of the storage battery box, a headlight switch, and a headlight switch. And removing the connectors arranged in the vicinity of the inner wall surface of the housing to reduce the outer size and miniaturize it, and to provide a device stand on the opposite side of the cab adjacent to the storage battery box. An equipment box is placed on the equipment stand, an air cylinder for operating a brake is provided under the carriage, and a receiver tank for supplying compressed air to the air cylinder by turning on an electric brake switch is vertically placed in the equipment box. In this state, the device stand is pierced through, a compressor for supplying air into the receiver tank to increase the pressure to a predetermined air pressure and a compressor motor for driving the compressor are provided in the device box, and 2t is provided at an appropriate position on the chassis. A vehicle speed detector for detecting the speed of the storage battery locomotive is provided, and the current supplied to the motor for driving the locomotive when the vehicle speed detected by the vehicle speed detector exceeds a predetermined upper limit and a predetermined speed. The 2t storage battery locomotive is stopped at a predetermined speed range by supplying current to the motor for driving the locomotive when it stops and drops below the predetermined lower limit speed. A speed control device is provided to control the vehicle so that it travels in the surrounding area. Then, the electric brake switch is provided with an oscillator at a predetermined position on the rail side, the electric wave of a predetermined frequency emitted from the oscillator is caught, and the power brake is operated to automatically move to the predetermined position. By making the fixed position automatic stop device that is stopped to operate in conjunction therewith, the fixed position automatic stop device can be automatically and surely stopped. Furthermore, if the speed control device is provided with an alarm device that gives an alarm when the speed of the 2t storage battery locomotive reaches a predetermined upper limit predetermined speed, the driver is notified that the upper limit predetermined speed is reached. It is the one.

[Action]

When a Zlitro is towed by a 2t storage battery locomotive on a rail laid in a tunnel with a diameter of about 2.5m, and a person is not seated in the chair of the cab, the travel switch does not operate, 2t storage battery locomotive does not run unattended due to malfunction. When a 2t storage battery locomotive is running and the electric brake switch is turned on to apply braking, the receiver tank opens and the compressed air in the receiver tank is supplied to the air cylinder to operate. The brakes are applied to the wheels by the operation of the air cylinder, and the 2t storage battery locomotive is reliably braked by the pressure of the air cylinder. Air is supplied to the air cylinder to send air to the receiver tank whose pressure has dropped to raise the pressure.Therefore, the compressor motor turns on and the compressor operates, and the receiver tank has a specified amount of air.
Operates until pneumatic pressure is reached. Also, while the 2t storage battery locomotive is running, the speed of the 2t storage battery locomotive is detected by the vehicle speed detector attached to the chassis, and the speed of the 2t storage battery locomotive is determined based on the detected value, which is a predetermined upper limit. When the speed is exceeded, the supply of electric current to the motor for driving the locomotive is stopped to prevent the speed from further increasing. Also, when the speed of the 2t storage battery locomotive based on the detection value of the vehicle speed detector falls below a predetermined lower limit, the 2t storage battery engine is supplied again to the motor for driving the locomotive. Increase the speed of the car. In this way, the speed of the 2t storage battery locomotive is controlled within the predetermined speed range. Furthermore, when the 2t storage battery locomotive runs and reaches a predetermined position, it captures radio waves of a predetermined frequency emitted from an oscillator installed at a predetermined position on the rail side, and the electric brake is automatically activated by the operation of the fixed position automatic stop device. Switch on and operate the power brake to automatically and reliably stop the 2t storage battery locomotive at a fixed position. Also, when the speed of the traveling 2t storage battery locomotive reaches a predetermined upper limit, a warning is issued.
