Conventional wheels with wheels used for railway vehicles are transported on a rail without raising the wheels, and then the rails are raised by hydraulic pressure, etc., and the wheels are moved down the rails in the raised position .

 When the shaft is moved in this manner, the transporting operation is repeated several times because it moves to a desired place. Therefore, a lot of time and manpower are required, and a person may be injured if there is a person during the transporting process. The moved shaft has been performing necessary work such as maintenance or repair by equipment such as a shaft press or the like at the moved position.

Since the wheel axle is a very heavy vehicle with the wheels and axles of the railway vehicle, it is very difficult to move such a wheel shaft, and a separate device for the movement is also used. In this case, separate equipment such as a crane or other heavy lifting device is required and the operation is very troublesome.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 shows a rudder transfer device (bogie) for explaining the present invention.

As shown in the drawings, the present invention is characterized in that a frame 100 is installed on a wheel 110, and parts such as a support plate 200 and a rotation shaft 330 are disposed on the frame 100, And to be able to descend.

A rotating wheel 310 including a bearing is installed on the outer circumference of the bottom of the rotating plate 300 so that rotation of the rotating plate 300 is smoothly performed. The rotation of the rotary plate 300 will be described below.

Reference numeral 210 denotes a shaft which is supported by a support plate 200 connected to an upper portion of the shaft 210 in accordance with the lifting and lowering of the shaft 210. The support plate 200 is mounted on the support plate 200 Up and down.

In the present invention, the counter weight (10) is provided below one side of the rotating plate (300). The reason why the count weight 10 is provided is to correspond to the weight of the opposite side of the drawing, that is, the weight of the lifting device 20 provided on the right side. Without such count weights 10, if the wheels are raised on the lifting device 20, the weight may cause operational hazards such as moving or tilting of the bogie.

The structure of the lifting device 20 is as follows.

A support base 22 is provided below the rotary plate 300 and a saddle 23 capable of receiving the axle 30 is connected to the support base 22. For reference, the wheel shaft 30 is generally referred to as an assembly including the shaft 31 and the wheels 33, as shown in Fig. The saddle (23) is formed with a receiving groove (24) capable of receiving the shaft (31) of the yaw shaft (30).

In addition, in the present invention, the support platform 11 is provided on the front and rear sides of the apparatus, and the detection sensor 12 is provided thereon. The sensing sensor 12 senses a person or object obstructing the forward movement of the wheel transporting device during the movement, so that the wheel transporting device is stopped or an alarm is sounded, and when the obstruction is removed, You may.

Fig. 3 is another embodiment of Fig.

In this embodiment, a wheel shaft support 301 is further provided on the rotary plate 300. That is, the wheel shaft 30 can also be mounted on the wheel shaft support 301. With this configuration, if necessary, the wheel shaft 30 can be moved and carried out after it is placed on the wheel shaft support 301 on the rotary plate 300 by using another lifting mechanism. With such a configuration, it is possible to move a large number of the wheel shafts 30 at a time, so that it is possible to remarkably reduce the labor and time required to perform the work of moving the wheel shafts one by one.

 When the rotation motor 302 installed on the lower side of the rotary plate of the rotation plate 300 rotates, the motor side spur gear 303 formed at the upper end of the motor rotates. When the spur gear 304 connected to the rotation side rotates, The rotary plate 300 connected to the gear 304 rotates.

Fig. 4 is a right side view of Fig. 3. Fig.

In this figure, the driving of the wheel 110 is illustrated. As shown in the figure, when the drive motor 230 is operated, the drive motor spur gear 231 rotates and the second spur gear 232 connected thereto is rotated, and the second spur gear 232 rotates the driven shaft 233 And the wheel 110 connected to the driven shaft 233 is eventually rotated.

Fig. 5 shows the arrangement of the power transmission device on the frame 100 for operating the up and down movement of the support plate 200 shown in Fig.

The elevation motor 241 is installed on the upper surface of the frame 100 and the power of the elevation motor 241 is transmitted to the shaft 210 in the cylinder 212 via the speed reducer 240 and the second speed reducer 242, . That is, the shaft 210 in the cylinder 212 has a helical type ascending and descending structure that is raised and lowered with a thread. Since this structure is widely used in the field of mechanical technology, a detailed description thereof is not necessary.

The operation according to the above configuration will be described below.

First, when the wheel shaft 30 placed on the rails is lifted, the lifting motor 241 of FIG. 5 is operated to lower the shaft 210. Then, the support plate 200 and the rotary plate 300 connected to the shaft 210 are lowered. The lifting device 20 having the support 22 formed on one side of the rotary plate 300 also descends. The lifting device (20) is integrally connected via a support (22). When the lifting device 20 is lowered, the height of the saddle 23 is sufficiently lowered to be placed below the position of the shaft 31 of the shaft 30.

6, the lifting device 20 is lowered and moved up and down to the position of the shaft 31 of the shaft 30 to move the shaft 31 of the shaft 30, which is placed on the floor or the rail, It can be made to come into the receiving groove 24 of the body 23. When the elevating motor 241 is operated to raise the rotating plate 300, the wheel shaft 30 is lifted to a predetermined height. When the driving motor 230 is operated, the wheel 110 rotates and travels on the rail.

After the wheel shaft 30 has been moved as described above, it is possible to smoothly perform necessary operations such as repair or replacement of the wheel shaft 30 by a desired operation such as raising or rotating the wheel shaft 30 together with the rotary plate 300 have.

According to the present invention as described above, it is not necessary to use a device for lifting separate weight such as various crane or other lifting device in order to raise the wheel shaft, and the wheel shaft 30 is lifted at a low height Since it moves up and down, the transfer of the axle shaft is convenient and the safety is guaranteed.

Further, when the wheel shaft 30 is lifted up to the lifting device 20, the count weight 10 is provided at the rear so as to cancel its weight, thereby preventing safety accidents due to inclination or movement due to the weight of the wheel shaft 30 can do.

In addition, a detection sensor (12) is installed at the front and rear sides of the wheel shaft conveying device so that when there is an obstacle or a person behind the wheel, a warning is sounded or automatically stopped, and if the obstacle is removed, Prevent industrial accidents and ensure more safety.

INDUSTRIAL APPLICABILITY As described above, the present invention greatly improves the safety and workability of a wheel-raising operation, thereby enhancing productivity.
