Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a track running device for a truck carrying ballast or 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 that supports the rails, etc. 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. Not only will the ballast be lost, but it will soon become distorted even after maintenance and repair, so it is necessary to replace the ballast at an appropriate time. 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, work efficiency is affected by the limited number of trolleys owned by the railway, the loss of travel time from the station to the work site, and the loss of the trolley schedule and related personnel schedules such as conductors and drivers. There was a drawback that it was bad.

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. It is a track running device for a truck which is fixed on a bogie 1 and has insulated tires 5, 5 on the rear wheels 4, 4 of the truck, the recess of the receiving part 8 of the bogie 1 being a fixed recess, A pair of front truck wheel slippage prevention bodies 6 and 6 are provided at required positions on the left and right sides of the receiving portion 8, corresponding to the outer sides of the left wheel 2 and the right wheel 2, respectively, of the front truck wheels.
Moreover, the base plate 10 is free from the truck body, and the insulated tire 5 is provided in the tire hole 14.
An insulating material 17 is attached to the outer periphery of the annular rim 12 on the outer periphery, and a metal tire 11 to be placed on a rail 19 is attached to the outer periphery, and between the metal tire 11 and the insulating material 17, , a pair of cone rings 1 whose taper directions are opposite to each other
Connection bolts 15, 15, 15 passing through 3, 13
He devised a device for transporting ballast, etc., with a structure that was tightened by There are the following advantages when using this device:

(i) It can set its own schedule without relying on railroad-owned trolleys.

(b) The time required for the trolley to arrive at the site and return can be utilized without wasting time. (This is because the trolley can be hooked onto and removed from the track using the nearest railroad crossing at the site.) (c) Efficiency in unloading work is significantly increased compared to conventional trolleys.

(d) With conventional trolleys, movement from point A to point B must always be on the track;
Although it may be necessary to spend the night just for transportation, using the present invention is efficient because it can be moved by itself on the road during the day even if the work location changes.

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

In the figure, reference numeral 1 denotes a truck 1 on which front truck wheels 2, 2 for running a truck transporting ballast, etc. on a track are mounted. A receiving portion (recessed portion shown in the figure) 8 for mounting the front truck wheels 2, 2 is provided in the central portion 9 of a base plate 10 on which the front wheels 2, 3, and 3 are mounted.
A truck front wheel tightening band 7 for tightening the truck front wheels 2, 2 (actually tightening the front wheels) is detachably attached to the front and rear positions of the truck. As shown in FIG. 1, the receiving portion 8 is provided at a position as low as possible, that is, at a low position to the extent that there is no possibility that the lower surface of the bogie will come into contact with the rail while the bogie 1 is traveling on the track. This is a fixed recess, which lowers the center of gravity of the entire traveling body and improves the safety of the vehicle as a whole. Truck front wheel slip-stopping bodies 6, 6 for preventing the front truck wheels 2, 2 from moving in the left-right direction are protrudingly provided at required positions on the left and right sides of the recess. The tire wheels 14 of the rear wheels 4, 4 of the ballast transport truck 20 have an annular rim 12 around the side of the drum.
An insulating material 17 is glued to the outer periphery of the rail 1.
An insulated tire 5 consisting of a tire 11 to be mounted on top of the tire 9 is attached. Numeral 15 is a connecting bolt for connecting the annular rim 12 and the tire 11. When the connecting bolt 15 is used, a pair of mutually connected bolts are provided on the outer periphery of the connecting bolt 15, as shown in FIG. Cone rings 13, 13 with opposite taper directions are interposed to firmly connect the two by utilizing a wedge effect. 16 is Natsu. The track running wheels 3, 3, 3, 3 are made of insulated tires. 18, 18 are handles, and the trolley 10
There are two pairs protruding from the front and rear of the .

The present invention has the above-mentioned structure and has achieved a device that is excellent in transporting ballast and the like.

In the past, in order to run a car on rails,
Various ideas have been proposed, such as the invention in Utility Model Publication No. 36-32324 and the invention in Japanese Patent Laid-Open No. 52-131309, but all of them were aimed at lightweight automobiles and could not be applied to heavy trucks such as those used to transport ballast.

As described above, the present invention has a receiving part 8 for mounting the front wheels 2, 2 of the truck for running on a track for transporting ballast, etc. The truck has a platform 10 on which wheels 3, 3, 3, 3 are mounted, and the receiving portion 8 is a fixed concave portion, and the front wheels 2 and 2 of the truck are connected to each other at required positions on the left and right of the receiving portion 8. A pair of front truck wheel slip prevention bodies 6 and 6 are provided protrudingly at the contact positions, and
By configuring the base plate 10 to be free from the truck body,
It can withstand the heavy burden of a truck transporting heavy ballast, etc., and the truck body can operate in a stable state, and it can also run stably even when the rail curves during operation, ensuring safety. This is a sufficient and truly excellent device for transporting ballast, etc.

Furthermore, the present invention provides track 2 as described above.
The insulated tire 5 provided on the rear wheels 4, 4 of 0 is an annular rim 12 on the outer circumference of the tire wheel 14 of the rear wheel 4.
An insulating material 17 is glued to the outer periphery of the rail 1.
9 Connect the metal tire 11 that should be mounted on the bolt 1
5, 15, 15, and a pair of cone rings 13, 13 with opposite tapered directions are interposed on the outer periphery of the connecting bolt 15, and a wedge action is used to tighten the cone rings 13, 13 on the tire wheel 14 side. Since the annular rim 12 and the metal tire 11 that should be in contact with the rail are extremely firmly connected, it is robust and safe and can withstand large loads, making it suitable as a track running device for trucks such as ballast transportation. It is excellent.
