て保線作業を行う。Demand for higher track maintenance work is increasing with the speeding up of railway wheels and the increasing operation density. Most of such track maintenance work is performed by using a work cart equipped with work equipment at night when the operation of the vehicle is stopped. FIG. 3 is a diagram for explaining the operation of the automatic alarm. When the vehicle (1) approaches the railroad crossing (5), the tracks (4) and (4) near the railroad crossing (5) are formed by a pair of vehicles (2) and (2) and an axle (3). The alarm device (51) continues to operate in response to a short circuit, the alarm lamp blinks, and the alarm sound continues to sound. FIG. 4 is a view showing a work carriage, that is, a main part of the work carriage. FIG. 4A is a front view thereof, and FIG. 4B is a side view thereof. That is, the wheel (2) is composed of an outer ring (21) and an inner ring (22), and an outer ring (21) and an inner ring (2).
It is electrically insulated from 2) by an insulator (23) such as rubber or plastic, and the outer ring (21) and the inner ring (22) can be electrically short-circuited or cut off by a manual switch (6). Constructed with insulated wheels. When the work carriage performs track maintenance work near the railroad crossing (5), the manual switch (6) is closed until it reaches the railroad crossing (5), and after reaching the work site near the railroad crossing (5). Open the manual switch (6) to open the outer ring (21) and inner ring (22).
Insulate and prevent lines (4) and (4) from being short-circuited. By doing so, the alarm line (51) is not operated and the sleep maintenance of the residents near the railroad crossing (5) is not disturbed.

It is difficult to open and close the manual switch (6). In such a case, move the work carriage forward or backward slightly so that the manual switch (6) does not face the lower structure (11) and then the manual switch. There was a problem that (6) had to be opened. This was even more difficult with more knitting. Further, there is a problem that the manual switch (6) or an automatic switch instead of the manual switch (6) cannot be provided between the lower structures (11) where the space for mounting the switch in a place different from the above is narrow. The present invention aims to solve such a problem.

不要である。In order to carry out track maintenance work with the work trolley of the present invention, the open / close switch (83) of the power supply (86) is opened while the vehicle departs from the base and runs toward the railroad crossing (5) which is the work site. Disconnect the circuit. In such a state, the coil of the relay (77) that opens the b-contact (9) is not excited, and therefore the outer wheel (21) and the inner wheel (22) are short-circuited, so an alarm that passes during traveling Go to the work site while operating (51). Immediately after reaching the work site and stopping, the opening / closing switch (83) of the power supply (86) provided on the chassis side is closed to close the primary circuit and the current from the power supply (86) to the primary coil (82). Sink and excite this. Then, in the yoke (81) of the primary coil, the axle (3) portion facing this, and the yokes (73) (73) of the axle, a magnetic circuit as shown by an arrow in Fig. 1 (c) is provided. It is formed. The secondary coil (75) wound around the position where the primary coil of the axle (3) faces the primary coil (82).
Since it is shared with the secondary coil (75), the primary coil (8
An electromotive force is induced by the mutual induction effect with the change of the current in 2). The current induced in the secondary coil (75) on the secondary circuit side in this manner is rectified into a direct current through the rectifier (76) and flows into the coil of the electromagnetic relay (77). This excites the coil of the electromagnetic relay (77),
This electromagnetic force causes the b contact (9) of the relay (77) to open. Thus, the outer ring (21) and the inner ring (22) are electrically disconnected, and therefore the pair of rails (4) and (4) are not short-circuited. Therefore, park the work site without operating the alarm device (51). You can The blue lamp (84) and the red lamp (85) provided in the primary circuit light up blue when the primary circuit is in a disconnection state and light up red when the primary circuit is in a disconnection state, and are not essential elements. The light emitting diode (78) in the secondary circuit emits light when the secondary circuit is closed,
The Zener diode (79) stabilizes the voltage, and these are not essential elements. In addition, the rectifier (76) is unnecessary when using the relay (77) that operates by alternating current.

Alternatively, it is possible to extend the hand from the side of the wheel to the back side of the wheel to eliminate the dangerous work of opening and closing the manual switch, and improve the work efficiency. Further, since the secondary coil is wound around the axle to form the axle as a part of the magnetic circuit, it is possible to install the necessary device in the narrow space of the lower structure of the work carriage.
