Next, a description will be given of an example of use of the wheelset hanging bracket of the present embodiment. First, as shown in FIG. 4, a case will be described in which a wheel set AX1 having a center of gravity near the center right is lifted. The wheel axle AX1 is a shaft member having wheels 3 on the left and right and a gear box 5 on the right side of the center. First,
The wheelset hanging bracket 10 is prepared, and the left and right ends of the wheelset AX1 are hooked by the left belt sling 32 supported by the left support portion 12 and the right belt sling 33 supported by the right support portion 13, respectively. Specifically, FIG.

Is in a state where it can be supported by the metal fitting body 11.

On the other hand, a plurality of engaging grooves 16a of the multi-engaging portion
Select the engaging groove 16c from 16h. That is, since the center of gravity of the wheel set AX1 in FIG. 4 is slightly to the right of the center, the locking groove 16 is positioned slightly to the right from the approximate center of the fitting body 11.
c is selected. The locking groove 16c is positioned in advance in consideration of the position of the center of gravity of the wheel shaft AX1. At this time, the wheel set AX1 is displayed on the display unit 21c (see FIG. 1) provided at a position corresponding to the engaging groove 16c.
Is written. Therefore, if the operator reads the display on the display unit 21c, it does not take much time to select the engaging groove 16c, and there is no possibility that the operator may erroneously select anything other than the engaging groove 16a.

Then, one end of the mastering 20 is hooked on the hook groove 16c, and the other end is hooked on the hook F of the crane. If the crane is raised in this state, the wheel set AX
1 is lifted in a state where the right and left sides are balanced. In this state of lifting, even if vibration or the like is applied to the wheel set AX1 or the wheel set hanging bracket 10, the mastering 20 cannot insert the partition plate 19 into the central hole 20a, and thus comes off the hook groove 16a. That is, the wheel set AX1 is maintained in a state of being balanced.

Next, a description will be given of a case where a wheel set AX2 having a center of gravity as shown in FIG. 5 is lifted. The wheel axle AX2 is a shaft member having wheels 3 and 3 on the left and right, and further separate parts 7 and 7 are attached so as to be symmetrical.

Hook the left and right ends of 2 respectively. The wheel set A
Since X2 does not have a gear box, the gear box support 14
The belt sling 34 for the gear box supported by the
b is hooked on the gear box support portion 14 (that is, the gear box belt sling 34 is not used). As a result,
The wheel set AX2 is in a state where it can be supported by the bracket main body 11.

On the other hand, a plurality of engaging grooves 16a of the multi-engaging portion
Select the latching groove 16a from ~ 16h. In other words, since the position of the center of gravity of the wheel set AX2 in FIG. 5 is at the center, the engaging groove 16a located substantially at the center of the bracket main body 11 is selected. The locking groove 16a is positioned in advance in consideration of the position of the center of gravity of the wheel shaft AX2. At this time, this hook groove 1
The name of the wheel set AX2 is written on the display unit 21a provided at a position corresponding to 6a. Therefore, the operator reads the display on the display unit 21c,
It does not take much time to select c.
There is no danger of selecting anything other than.

Here, the mastering 20 is engaged with the retaining groove 16c.
First, when the mastering 20 is replaced with the retaining groove 16a, the mastering 20 is moved so that the major axis thereof is oriented substantially in the horizontal direction.
Is changed (see the two-dot chain line in FIG. 3), and in this position, the mastering 20 is moved to the engaging groove 16a such that the partition plate 19 is inserted through the central hole 20a. Then, one end of the mastering 20 is hooked on the hook groove 16a, and the other end is hooked on the hook F of the crane. If the crane is raised in this state, the wheel set AX2 is lifted in a state where the left and right balance is maintained. In this suspended state, even if vibration or the like is applied to the axle AX2 or the axle suspension fitting 10, the mastering 20 cannot insert the partition plate 19 into the center hole 20a, and thus comes off from the engaging groove 16a. That is, the wheel set AX2 is maintained in a balanced state.

In FIGS. 1 to 3, for convenience, the mastering 20 is shown in a posture in which the major axis faces in the vertical direction. However, the mastering 20 is not actually hooked on the hook F of the crane (from the mastering 20 to the hand). 6), the main body is left in a posture in which the major axis faces obliquely as shown in FIG. Also in this case, since the partition plate 19 cannot be inserted through the center hole 20a, the mastering 20 does not come off from the selected engaging groove.

According to the embodiment described above, the following effects can be obtained. A state in which various wheel sets are balanced by a simple operation of selecting one corresponding to the position of the center of gravity of the wheel set to be lifted from among the plurality of locking grooves 16a to 16h and hooking one end of the mastering 20 there. Can be lifted.

The operator has a plurality of locking grooves 16a to 16h.
Of the wheelset to be lifted and the display unit 21
Since it is only necessary to select a locking groove that matches the type indicated by a to 21h, it does not take much time to select the locking groove, and there is no risk of selecting an incorrect locking groove.

The gear box 5 is connected to a gear box belt sling 34.
The gear box 5 can be prevented from rotating during lifting by supporting the gear box 5 on the gear box support portion 14 through the support. When the mastering 20 is moved to another engaging groove, the major diameter of the mastering 20 must be oriented in a substantially horizontal direction, so that the mastering 20 is not easily detached from the once selected engaging groove. For example, in FIG. 4, even if vibration or the like is applied to the wheel set AX1 or the wheel set hanging bracket 10 while the wheel set AX1 is being lifted, the mastering 20 does not come off from the selected engaging groove 16a. Are kept in a balanced state.

The embodiments of the present invention are not limited to the above-described embodiments, and it goes without saying that various forms can be adopted as long as they fall within the technical scope of the present invention. For example, in the above embodiment, the oval-shaped mastering 20 is employed as the relay member. However, the relay member is not particularly limited to this shape. For example, a hook formed in a substantially S shape may be employed.

In the above embodiment, the wheel sets AX1 and A
Although a shaft member having wheels on the left and right has been exemplified as X2, a shaft member having no wheels on the left and right may be lifted. Further, in the above embodiment, the display units 21a to 21a
Although a tape in which the type of the wheel set is described is adopted as 21h, the display unit is not particularly limited thereto. For example, the type of the wheel set may be displayed in different colors.
