Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a point device for a double-track monorail track.

The secondary monorail rolling device will be explained with reference to FIGS. 1, 2, 3, and 4.

As shown in the conventional figure 1, there are four point machines 5, each of which is installed horizontally rotatably on fixed girders 1, 2, 3, and 4.
In the case of a plurality of monorail switch devices in which the switches 6, 7, and 8 are connected together, when the switch is carried out in an intersecting manner, that is, when the switch is carried out in the state shown by the dotted line and the chain line in the figure, the switch 6 and A gap 12 is created between the points 7 or between the switches 5 and 8. For this reason, as shown in Fig. 2, there is a method of providing an auxiliary girder 9 to compensate for the gap 2 and extending it in the connection direction.
Alternatively, as shown in FIGS. 3 and 4, the point device 5,
A connecting plate 10 is fixed to the tip of the switch 6, a finger plate 12 is fixed to the tip of the switch 7, 8, a cylinder 17, a lever 13 that swings around a fulcrum 15, and the lever 13 and the cylinder 17 are connected to each other. A method is used in which the gap 12 is compensated for by sliding the finger plate 11 fixed to the receiver 14 in the longitudinal direction by means of a connecting lever 15. In a switch device as shown in Fig. 1, in which four switch devices that are not structured to expand and contract in the longitudinal direction are aligned, the gap 12 that occurs when moving from a straight line to a curved line is The auxiliary girder 9, the connecting plate 10, and the finger plates 11 and 12 as described above are attached to reduce the temperature. However, in this method, it is necessary to provide an auxiliary girder 9 separately from the point device and rotate it according to the direction of the point, and it is not related to the point mechanism in which the finger plate 11 is slid in the direction of the point. In order to provide a device without a structure, the control mechanism has become complicated.In view of the above points, the present invention combines a point device that expands and contracts in the longitudinal direction when making a point, and uses an auxiliary girder or connecting plate, etc. The purpose of this invention is to obtain a switching device that does not require any additional equipment and has a simple structure.

The present invention employs an articulated point device consisting of a plurality of point girders in a double track point device in which four point devices are tied together, and connects the point girders. An elongated hole is provided in the bearing part of the shaped pin, and a guide book with a trolley attached to the pet plate has a structure that allows it to expand and contract in the longitudinal direction, so that it can be extended in the longitudinal direction at the same time as the point using the point driving force. It is characterized by what it did.

Next, the present invention will be explained with reference to an embodiment shown in FIGS. 5, 6, 7, 8, 9, and 10.

One point device is shown in FIGS. 5 and 6. 20, 21,
Reference numerals 22 and 23 are point girders for point equipment, which are connected in an articulated manner by a T-shaped pin 24 shown in FIG.

Reference numerals 25, 26, 27, 28, and 29 are carts that support the point girders 20 to 23. 26, 27 and carts 28, 29 are even-numbered point girders 21 and 2.
It is attached to the convex lower surface of both ends of 3. In addition, each trolley 25
, 26, 27, 28, 29 have pet plates 3 at the bottom.
Guide grooves 36 and 37 are provided in a pet plate 35 provided at the lower part of the carts 26 and 28, and the carts 26 and 28 have guide arms 38 and rollers 39 that are fitted in the guide grooves 36 and 37. is installed. Note that a rack, pinion, etc. may be used in place of the guide grooves 36, 37 and rollers 39. As shown in FIG. 7, the vertical portion A of the T-shaped pin 24 is rotatably connected to the convex portions 40' of the point girders 21 and 23 to which the carriage 26 is attached.

Further, the horizontal portion B of the T-shaped pin 24 is connected to the point girders 20 and 2.
The bearing 33 provided on the lower surface of the fishing groove recess 41 of No. 2 is filled with iron. The bearing 33 has the T-shaped pin 2 with a length of 12/6.
An elongated hole 34 whose number 4 corresponds to the horizontal portion B is provided. In FIG. 6, an electric motor 30 and a drive shaft 38 are provided at the center of the lower surface of the point girders 21 and 23, and carts 26 and 27 and carts 28 and 28 are fixed to both ends of the point girders 21 and 23, respectively. 29 is driven.
Note that the carts 26, 27, 28, and 29 perform the transfer by meshing gears of a drive mechanism driven by a drive shaft 31 with a rack 32 provided on a pet plate 35 and driving the gears. Figure 6 shows the state of the point equipment on a straight line, and the point girders 20, 21, 22 at this time
, 23 are maintained at a dimension a by guide arms 38, rollers 39, and guide registers 36 and 37 provided on the carriages 26, 28. FIG. 9 shows the relationship between the carriage 28 and the guide groove 37. Figure 10 shows the point on the curve, i.e.
The figure shows the state where it has fallen to the position indicated by the chain line. At this time, the gap between the point girders 20, 21, 22, and 23 is moved by 12/6 in the longitudinal direction at the same time as the point girders 20, 21, 22, and 23 are guided by the guide grooves 36 and 37, and becomes a112/6. If four of the above-mentioned point devices according to the present invention are combined to form a double track point device shown in FIG. The structure is simple because the point device itself expands and contracts by 12/2 of its length simultaneously with the point and by using the point driving force without providing any special devices such as the plate 10 or the finger plates 11 and 12. As it becomes more reliable, its operation becomes more reliable.

As explained above, according to the present invention, by configuring a double track point device by combining four point devices that can be expanded and contracted in the longitudinal direction, there is no need to provide auxiliary girders, connection plates, etc., and the structure is simple. You can get a point device.

In addition, since the rolling girder is expanded and contracted by the rolling force at the same time as the rolling stock, operation is reliable.
