Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a track running device for trucks for transporting ballast and the like.

As the passenger transport capacity increases year by year, the number of trains passing through the tracks is also increasing, and one way to prevent the safe lifespan of the tracks from decreasing is to replace the ballast. Ballast is located on the roadbed and is an important part of supporting the track. However, if the durability of the roadbed is significantly impaired due to the repeated loads of passing trains and mud being sprayed from the roadbed, the track will go awry and safety will be compromised. It is necessary to replace the ballast at an appropriate time, because not only will it be lost, but it will soon go out of order even after maintenance and repair. For this reason, trolleys have been used to transport ballast, but trolleys are inefficient because ballast replacement is carried out during a limited time at night when trains are not running. In other words, there is a limit to the number of trolleys owned by the railway, loss of travel time from the station to the work site, trolley schedules and related command vehicles,
The disadvantage was that work efficiency was poor due to the loss of scheduled personnel such as drivers.

In view of this drawback, the present inventor proposed that the front wheels 2, 2 of a truck for ballast transportation, that is, a dump truck that can tilt the ballast loading platform to the left and right and rearward when traveling on ordinary roads, be used for track running. A device was devised for transporting ballast by fixing it on a trolley 10 and running on rails 19 with insulated tires 5, 5 attached to the rear wheels 4, 4 of the truck. 2019 Utility Model Registration Application No.

The present invention is a further improvement of the invention.

In other words, there are mainly narrow gauge, wide gauge (international standard gauge), and intermediate gauge tracks on which this device is used, and it is preferable from a cost standpoint to manufacture separate devices for each type. Therefore, the present invention was devised to solve this problem.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the figure, reference numeral 10 indicates front wheels 2, 2 of a truck for running the truck on the track for transporting ballast, etc.
The trolley 10 carries track running wheels 3, 3, . . . on its shaft. Reference numeral 8 denotes a truck front wheel holder for mounting the truck front wheels 2, 2. 20 is a truck for transporting ballast, etc., and an insulated tire 5 to ride on a rail 19 is attached to the rim 14 (outer peripheral wall of the brake drum) of the rear wheels 4, 4 of the truck 20 for transporting ballast, etc. . As the gauge of the track on which the truck 20 for transporting ballast, etc. is to run is broad gauge or intermediate gauge rather than narrow gauge, the left and right tires 5 and 5 are adjusted accordingly.
The rim 14
An attachment disc body 30 of a required thickness that can be attached and detached by tightening bolts is attached to the attachment disc body 30, and a tire 5' having the same shape and dimensions as the tire 5 is attached to the attachment disc body 30, and a wheel having the same shape and dimensions as the tire wheel 14 is attached to the attachment disc body 30. The outer diameter of the attachment disc 30 is such that it can be inserted into the wheel body 14'.

The bogie 10 is composed of two left and right platform plates 21, 21 each having track running wheels 3, 3, and the bogie disks 21, 21 are configured to have left and right platform plates 21, 21 equipped with track running wheels 3, 3. In order to adjust the distance between the wheels 3 and 3, the left and right base plates 21, 21 have one part 23 slidably inserted into the other part 24, and are inserted at required positions, respectively. Bolt insertion hole 2
2, 22... (see Figures 2 and 3). Alternatively, the bogie 10 may move the left and right wheels 3 according to the size of the gauge of the track on which it is to run.
and 3 so that the distance between the wheels 3 and 3 can be adjusted.
The wheel position converting means 1 is provided on the axle support portion 25 of . . . (see FIGS. 4 to 6).

As shown in FIG. 1, FIG. 2, and FIG. , 2 is provided with a receiving part (a concave notch in the drawings of the embodiment) 8, and the receiving part 8 is provided at a predetermined position for locking the front wheels of the truck to prevent the front wheels 2, 2 from moving in the left and right direction. The fasteners 7, 7 are detachably attached by tightening bolts.

In the insulated tire 5' shown in FIG. 9, an annular rim 12 fixed to the outer circumference of the wheel body 14' and the tire 1
A connecting bolt 15 for connecting 1 is shown. When using the connecting bolt 15,
Cone rings 13, 13 are interposed before and after this to firmly connect the two by utilizing a wedge effect. 16 is Natsu. An insulating material 17 is interposed between the cone ring 13 and the annular rim 12 so that the track running wheels 3, 3, 3, 3 are insulated tires.

A wheel position converting means 1 is shown on a truck 10 shown in FIGS. 4 to 6. FIG. Axle support part 25 of wheel 3
The upper part is formed into an inverted trapezoidal part 26, which is fitted into a groove 28 bored in the left-right direction in the bottom wall of the base plate 27, and is bolted at a required position. In the figure, 29 indicates a bolt/nut.

The present invention has the above-mentioned configuration, and the distance between the left and right tires 5 is adjusted in accordance with the fact that the gauge of the track on which the truck 20 for transporting ballast, etc. runs is wider or intermediate gauge than narrow gauge. In order to increase the size of the vehicle, the bogie 10 is composed of two left and right base plates 21 and 21 equipped with wheels 3, 3 for running on tracks, and the base plates 21 and 21 are equipped with the gauge gauge of the track on which it is to be run. The left and right base plates 21 and 2 are arranged so that the distance between the left and right wheels 3 can be adjusted depending on the size of the wheels.
1 is one in which a part of the other is slidably inserted into a part of the other, and bolt insertion holes 22, 22, .
By bolting the two together, one truck for ballast transportation, etc. can be used for wide gauge, narrow gauge, or intermediate gauge, and can also be used as a heavy vehicle called a truck. This provides a truly rational track running device for trucks for ballast transportation, etc., which can sufficiently support the front half of the vehicle.
