Abstract

PROBLEM TO BE SOLVED: To improve stability of suspending work by arranging a plurality of rope suspending straight line horizontal pin holes parallel to a track rail on the upper crane side of a tip metal fitting and horizontal pin holes which are parallel to the track rail on the lower rolling stock suspending side and incline with a suspending bar axial center point as the symmetry. SOLUTION: A connecting surface to connect a suspending bar parallel to a track rail by a bolt, is provided in a horizontal position of upper crane suspending rope connecting straight line horizontal pins 10 and 11 of a suspender tip metal fitting 3, and two sets of suspenders can be combined with each other by the suspending bar. According to this two-suspender constitution, wheel suspending belts 12 and 13 are inserted inside front and rear wheels 9 of a bogie 8, and the suspending belt 12 is connected to the horizontal pin 10, and the suspending belt 13 is connected to the horizontal pin 11, and since the bogie 8 is suspended by the two suspending belts, the center of gravity of the bogie 8 is positioned between the suspending belts, and the bogie 8 can be suspended in a stable condition. Therefore, stability of suspending work is increased, and safe suspending work can be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspending device for a railway vehicle, and more particularly to a suspending device which is effective for returning a derailed vehicle.

[0002]

2. Description of the Related Art A conventional technique will be described with reference to FIGS. A suspending rod 2 of a balance is provided in the direction of a sleeper of a railway vehicle, and a hanging rope 1 is attached to both end fittings 3 of the suspending rod 2.
Pin 4 for connecting vehicle suspension belt 6 to lateral pin 4 for connecting vehicle
Are provided in parallel with each other. The suspension rope 1 is connected to the horizontal pins 4, the vehicle suspension band 6 is connected to the horizontal pins 5, the vehicle 8 is held, and the vehicle is lifted by one of the suspension bands 6.

[0003]

In the prior art, since one suspension band for a vehicle is lifted by holding it on a truck portion, it is necessary to fix the truck and the vehicle body separately. In addition, during the lifting, it is difficult to hang the center portion of the trolley, and the hanging becomes unstable, and the lifting work is complicated.

[0004] In addition, at a certain point of the train line, there is a problem that it is necessary to remove the train line in order to prevent the hanging rope from contacting the train line.

[0005] The present invention is a hanging tool which solves these problems.

[0006]

Means for Solving the Problems An unstable single suspension is connected to two
The stability has been improved assuming that the center of gravity of the suspended product comes between the suspension belts in the main suspension.

[0007] A gondola-type hanging structure in which two sets of hanging rods can be connected by connecting rods is used, and two sets of hanging tools are connected in the line of a train so that hanging work can be performed on both sides of the line.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In FIGS. 1 to 4, a hanging rod 2 of a balance provided in a sleeper direction, a tip metal fitting 3 connected to both ends of the hanging rod 2 with bolts Ba or the like, and a hanging part for lifting with a crane truck above the tip metal fitting 3. A straight horizontal pin 4 parallel to the track rail connecting the rope 1 for use, and a lower part of the tip fitting 3 is parallel to the track rail connecting the suspension bands 12 and 13 for lifting the vehicle, and the axis center point of the hanging rod 2 is symmetrical. The horizontal straps 10 and 11 are provided at right angles to the suspension band, and the horizontal pins 10 and 11 are attached to the lower surfaces of the lower horizontal pins 10 and 11 of the tip fitting 3. It is composed of a track rail for connecting a suspension band 6 for lifting a vehicle by one, and an orthogonal horizontal pin 5.

Next, a description will be given with reference to FIGS. 5, 6, 7 and 8. FIG. 5 is a connection surface view of the hanging tool, FIG. 6 is a view in which two sets of hanging tools are combined, and FIGS. 7 and 8 show examples of hanging.

In FIG. 5 and FIG. 6, a suspension rod 15 parallel to the track rail is bolted to the horizontal position of the upper crane suspension rope connecting linear connecting pins 10 and 11 of the suspension tool tip fitting 3 with bolts Bb.
And the like, and a connecting surface 14 is provided for connecting the two hanging members, as shown in FIG.

According to this two-row suspension structure, the vehicle suspension bands 12, 13 are passed through the inside of the front and rear wheels 9 of the bogie 8, and the suspension bands 12
Is connected to the horizontal pin 10 and the suspension band 13 is connected to the horizontal pin 11, and the carriage 8 is lifted by the two suspension bands. Therefore, the center of gravity of the carriage 8 is located between the suspension bands, and the carriage 8 is lifted in a stable state. Can be done. Therefore, since the carriage can be stably suspended, there is no need to secure the vehicle body 7 and the carriage 8 and the workability is improved. In addition, a gondola-type suspension method as shown in FIGS. 7 and 8 can be performed, and two and four vehicle suspension bands can cope with heavy operations such as a locomotive lifting operation.
In such a case, a hanging operation suitable for a hanging place can be performed, such as hanging two cranes with two cranes avoiding the trolley line 16 where the trolley line 16 is located. The horizontal pin 5 at the lower part of the tip fitting 3 is provided so that the lifting operation can be carried out even with a single hanging band as in the past. In the case of a gondola style hanging, one hanging can be used properly, and versatility can be achieved. Metal fittings.

[0012]

As described above, according to the present invention, since the vehicle is hung by two suspension bands, the stability of the suspension operation can be increased, and a safe suspension operation can be performed. In addition, the weight can be increased by combining two suspenders. There is an effect that a large car can be lifted and a vehicle can be lifted at a train line point.
