DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.
This will be described with reference to FIG.

FIG. 1 is a front view showing a state in which an electronic device rack is being moved by a trolley showing one embodiment of the present invention, FIG. 2 is a front view of a trolley showing one embodiment of the present invention, and FIG. FIG. 4 is a perspective view of a transport frame showing one embodiment of the present invention, FIG. 5 is a perspective view of an example of an electronic device rack to be moved, and FIG. It is a perspective view in the state where the transportation frame which shows one embodiment of the present invention was attached to the electronic equipment stand.

A transport frame 1 according to one embodiment of the present invention.
As shown in FIG. 4, an elongated opening 1a is formed in the vertical portion of the carrying frame 1 in the horizontal direction at a plurality of intervals. As shown in FIG. 3, the carriage 2 has a support frame 3 which comes into contact with the transport frame 1, a jack base 4 which engages with the support frame 3 and supports the support frame 3 so as to be vertically movable, and a support frame 3 and a jack base. A jack 5 attached to the jack 4 by a stud screw or the like to move the support frame 3 up and down; a pillar 6 attached to the jack base 4 by a stud screw; a base 7 attached to the pillar 6 by a stud screw; And the like, and a plurality of free casters 8 attached thereto.

[0010] Then, two transport frames 1 and a carriage 2
2 are used, and the cart 2 is connected to one side of each base 7 by a jumper 9 as shown in FIG. 2 and functions as a transport device for an elevator electronic device rack.

Next, the procedure for moving the electronic device rack shown in FIG. 5 will be described.

First, the electronic equipment rack 10 to be moved is
Elevator control panel, relay, contactor, printed board, etc., housed in a box shape, with at least both side walls protruding from the upper plate, and having a plurality of lifting openings 10a at the protruding portion. It is. When the transport frame 1 is attached, as shown in FIG. 6, the vertical portion of the transport frame 1 is brought into contact with the side wall of the electronic device rack 10 placed on the floor surface to form the opening 1a and the lifting opening 10a. Then, a bolt (not shown) is inserted into the aligned opening 1a and the lifting opening 10a, and the carrier frame 1 is fixed to a protruding portion of the side wall of the electronic device rack 10 by fastening with a nut (not shown). The transport frame 1 is also fixed to the opposite side (the protruding portion of the side wall on the opposite side) by the same procedure.

Next, the bogie 2 is held in a position where the support frame 3 of the bogie 2 is positioned parallel to and below the transport frame 1 with the jack 5 in the most contracted state, the jack 5 is extended, and the support frame 3 is lifted up. And brought into contact with the transport frame 1. The same operation is performed on the other side, and one side of each of the bases 7 of the two carts 2 is connected to each other by a jumper 9.

Next, the jack 5 is extended and the support frame 3 is extended.
Is lifted upward, thereby lifting the transport frame 1 fixed to one side wall upward. The same operation is performed on the other side, and the transport frame 1 fixed to the other side wall is lifted upward.

If necessary, the operation of the jack 5 is alternately repeated on one side and the other side of the side wall of the electronic device rack 10 so that the electronic device frame 10 is lifted up to the state shown in FIG. It is assumed that the lower surface of 10 is apart from the floor surface.

Thereafter, the electronic device rack 10 is pushed and moved to a desired position, the jack 5 is contracted, and the electronic device 10 is lowered on the floor.

At this time, if the electronic device 10 does not become horizontal, the jack 5 located at a low point is extended and slightly lifted, and after the liner is sandwiched between the electronic device frame 10 and the floor, the jack 5 is removed. The electronic device rack 10 is lowered. Placed horizontally (installed) in place
Then, the jack 5 is contracted, the two trucks are moved from the vicinity of the control panel with the jumper 9 attached, the bolts and nuts (not shown) are loosened, and the transport frame 1 is removed.

According to the above embodiment, the opening 1a of the carrying frame 1 is elongated in the horizontal direction, so that the carrying frame 1 can be attached irrespective of the interval between the lifting openings 10a of the electronic device frame 10. Becomes Further, the transport frame 1 only comes into contact with the support frame 3, and the transport frame 1
The electronic device rack 10 is lifted regardless of the width of the electronic device rack by making the horizontal portion without the opening 1a sufficiently large.
Can be transported.

Therefore, if this moving trolley is used, no screw hole is required on the side wall of the electronic device frame 10, and the electronic device frame 10 is kept horizontal from the floor while keeping the horizontal state, taking care of the tightness of the screwed portion. No need to lift, easily electronic equipment rack 1
0 can be lifted from the floor and transported.

In addition, since the two jacks 5 are used to lift the electronic device rack from the floor, the electronic device rack can be efficiently lifted from the floor with less labor.

[0021]

Since the present invention is constructed as described above, a screw hole is not required on the side wall of the electronic device rack, and the electronic device rack is kept horizontal from the floor while keeping the electronic device rack horizontal without worrying about the tightness of the screwed portion. There is no need to lift the electronic equipment rack, and the electronic equipment rack can be easily lifted from the floor and transported.
