JP2002127907A - Emergency transfer bogie for road/rail work vehicle - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a compact and lightweight emergency transfer bogie for a road/rail work vehicle allowing simple assembly and disassembly and capable of facilitating handling such as transportation and being stored in a small space. SOLUTION: This bogie 1 has a pair of axles 2 for loading wheels W of the road/rail work vehicle over between rails R and R of a railroad track. A guide wheel 3 rolling on the rails is rotatably supported on the axles 2. A detachable wire belt 4 is attached between both end parts of the axle 2. Wheel plates 8 are arranged on an inner side of the wire belt 4 and are bundled and fixed by a retaining ring 9, and a wheellike locking part 4a is formed in an end part thereof. A pin 6 protrudes from outer periphery of the axle 2 when inserted into an insertion block 5 to lock the wire belt 4. When the wheels W of the work vehicle are put on the axles 2 and are pushed forward, it moves on the rails R so that it can retreat from a main line when a failure such as derailment of the work vehicle occurs.

業車の応急移送台車を提供することを課題としている。In the above-mentioned conventional emergency transfer cart, the axles are connected by side frames. However, since the side frames are made of steel, the weight is large. Also, since the bogie is assembled by connecting the axle with the side frame, it is difficult to handle because it is connected with steel materials and it takes time to assemble,
It is troublesome to position the mounting of the receiving plate of the wheel and the mounting base of the wheel axle housing. Further, there is a problem that when the cart is stored in an assembled state, a bulky and unnecessary storage space is taken. Therefore, an object of the present invention is to provide a lightweight and compact emergency transfer vehicle for a track-and-ground work vehicle that is easy to assemble and disassemble, easy to handle for transportation and the like, and does not take up unnecessary space for storage.

が極めて簡単である。In the emergency transfer cart 1, a stop ring 9 is fitted to a belt 4 having an inter-axle plate 8 disposed inside to form locking portions 4a at both ends, and the axle 2 into which the insertion block 5 is fitted. , The hook 4a is hung, and the pin 6
Into the insertion block 5 to assemble. Then, the vehicle C is lifted by necessary means such as a turntable mounted on the vehicle C to lift the wheels W, and the emergency transfer cart 1 is placed under the front and rear wheels W on the rail R, respectively. Then, the wheels W are mounted between the front and rear axles 2 and 2, respectively. When the wheel W is mounted on the axle 2, the distance between the wheels is increased, but the axle 2 is connected by the wire belt 4, so that the expansion is prevented and the wheel W is held without falling off. Therefore, if the vehicle C is pushed forward, the guide wheel 3 of the bogie 1 rolls on the rail R and the rail R
The rail can be moved upward, thereby avoiding a closed state of the track at the time of an accident such as derailment of the track and land vehicle C. Note that the bogie 1 is used for both front and rear wheels, and the front and rear directions of the bogie 1 may be arranged in any direction. If the wire 4 is detached from the axle 2, it can be easily handled during storage and transportation, thereby preventing loss and the like. When not in use, the pin 6 is connected to the insertion block 6 by the locking wire 7, so that the pin 6 can be prevented from being lost without separating from the axle 2. The operation of the truck 1 is extremely simple because it is not necessary to mount the truck 1 on a portion other than the wheels W such as the wheel shaft of the vehicle C when the wheels W are mounted.
