Description

[Detailed Description of the Invention] << Industrial field of application >> This invention is, for example, in a tunnel under excavation by the shield method, in which a wheel of a work vehicle such as a truck that runs on a pair of rails laid on sleepers is temporarily used. The present invention relates to a wheel stopper device on a rail used for stopping.

<Prior art> For example, in a pressure shield construction method, when a rail type vehicle in which a locomotive, a shear steel car, or a shuttle car is connected to a battery locomotive is passed through the air lock chamber provided as pressure air equipment, It is necessary to stop the vehicle at a predetermined position when opening and closing. Then, in order to surely stop the vehicle on the rails, conventionally, independent wheel stopper members are respectively placed on the rails, and holes provided at predetermined positions of the rails and holes provided in the wheel stopper members are provided. It was made to match, the pin was penetrated there, and the wheel stopper was being fixed on the rail. When the vehicle is traveling, the pin is pulled out from the hole and the wheel stopper member is removed from the rail.

<Problems to be solved by the invention> However, when the cross-sectional area in the tunnel is small, in particular, since the passage for the worker can be provided only on one side of the rail, two wheel stopper members are provided on the two rails. As described above, the work of attaching and detaching each is very troublesome. Also, although the work of attaching and detaching the wheel stoppers to the rails on the aisle side is relatively easy, the work of attaching and detaching the wheel stoppers is very troublesome for the rail on the side opposite the aisle because the space between the vehicle and the tunnel wall is narrow. There was a risk that my limbs would get caught.

The present invention has been made in view of the above-mentioned problems of the related art, and an object thereof is to provide a wheel stopper device on a rail for easily attaching and detaching the wheel stopper even in a narrow tunnel or the like. It is in.

<Means for Solving the Problems> The present invention was made in order to achieve the above object, and its gist is to temporarily stop the wheels of a vehicle traveling on a pair of rails laid on a sleeper. A wheel stopper device on a rail, which is located diagonally below and on the same side of each rail, and which extends and protrudes from the sleeper along each rail, and is synchronized in the same direction about each of these rotation axes. It has a pair of L-shaped arms that rotate, and this L-shaped arm positions the inside of one side of the wheel stopper on the upper surface of the rail in the operating state of the wheel stopper, and attaches the wheel stopper member to the front side of the one side. A connection for vertically erected on the upper surface of each rail and for synchronously rotating the pair of L-shaped arms at the end of the other side of the L-shaped arm opposite to the one side sandwiching the rotary shaft. Take the rod Further, one end of an operation lever that extends to the side of the rail and then extends upward while avoiding an area occupied by the cross section of the vehicle at the end of at least one of the L-shaped arms on which the connecting rod is attached. And a pair of L-shaped arms are synchronously rotated about the rotation shaft via the operation lever, whereby the wheel stopper member is detachably operated from the upper surface of each rail. It is in the wheel stopper device.

<Operation> According to the wheel stopper device on the rail of the present invention, the pair of L-shaped arms, one end of which is connected by the connecting rod, are operated by operating the operation lever at a position avoiding the sectional area occupied by the vehicle. The rails are synchronously rotated in the same direction about a rotation shaft located diagonally downward on the same side surface side of each rail, and by this rotation operation, a wheel stopper member attached to the front side of one side of the L-shaped arm is attached to the upper surface of each rail. It can be easily attached and detached.

<< Embodiment >> FIGS. 1 to 3 show the construction of an embodiment of the present invention. In the figure, 1 is a cylindrical segment that constitutes a tunnel wall, and 2 is a sleeper that is installed so as to be hung across the floor portion in the tunnel in the width direction, and between the cylindrical segment 1 and the sleeper 2. An underfloor space 3 is formed in the room.

Then, two rails 4 are laid so as to be orthogonal to the sleepers 2, and the arm 6 bent in an L shape is positioned diagonally below the same side surface of the pair of rails 4,
Sleeper 2 via bracket 5 attached to the side of sleeper 2
Installed on. Here, the arm 6 has a rail-type cross-section stopper member 10 fixed to the front side of one side thereof, and extends from the bracket 5 or sleeper 2 along each rail 4 at the central portion of the other side. A fulcrum shaft 7 as a rotary shaft is penetrated through, and each arm 6 can rotate about the fulcrum shaft 7 in a direction orthogonal to the rail 4.

Further, the base ends of the pair of arms 6 are connected by an interlocking link 8 serving as a connecting rod, whereby both arms 6 are synchronously rotated in the same direction with respect to the rail 4 in the same phase. ing.

Further, the base end of the operating lever 9 is connected to the base end of the one arm 6 to which the interlocking link 8 is connected. That is, the base end sides of the interlocking link 8 and the operating lever 9 are the sleepers 2
Is disposed in the underfloor space 3 below, and the operation lever 9 is extended to the side of the rail 4 and then to the upper side while avoiding the sectional occupation area of the vehicle traveling on the rail 4. ,
The tip side thereof extends to the side of the rail 4 on the side of the passage.

Further, according to the wheel stopper device of this embodiment, when the operating lever 9 is brought to the position indicated by the solid line in FIG. 2 when the wheels are stopped, both arms 6 rotate synchronously and stand up substantially vertically. One side is located on the upper surface of the rail 4, and the wheel stopper member 10 attached to the front side thereof is located just above the rail 4. In this state, as shown in FIG. 3, the wheels 11 of the vehicle on the rail come into contact with the wheel stopper member 10 and stop.

On the other hand, when the operation lever 9 extending to the passage side is displaced from the solid line position to the dotted line position by the dotted line position, the interlocking link 8 causes both arms 6 to rotate in the same phase in the direction of the arrow A and to lie down substantially. Then, the wheel stopper member 10 is arranged at a position largely separated laterally of the rail 4. In this state, the vehicle on the rail can travel without any obstacle.

<< Effects of the Invention >> As described in detail above, according to the wheel stopper device on the rail according to the present invention, the rail cross-section occupying area of the vehicle is avoided while avoiding the cross-sectional occupied area of the vehicle, although the device has a simple structure. The wheel stopper member can be attached to and detached from the upper surface of each rail by a simple operation of operating the operation lever that extends to the side and then extends upward to rotate the pair of L-shaped arms in synchronization. The vehicle traveling above can be easily stopped by a manual operation, and the stopped state can be easily released.
