TECHNICAL FIELD [0001] The present invention relates to a direction switching device for a rotor disassembly of a vertical motor,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotor direction switching device, and more particularly, to a rotor direction changing device for rotatably and horizontally reversing a rotor mounted on a vertical motor will be.

Vertical motors are commonly used to support the weight of industrial motors such as submersible motor pumps, and the weight and light thrust of dual excitation generators for wind and algae power generation.

Such a vertical motor is provided with a bearing for rotating the rotary rotor at a fixed position and for rotating the rotary rotor while supporting the weight of the rotary rotor and the load applied to the rotary rotor.

As a conventional example of such a vertical motor, Patent Application No. 2013-88501 has proposed a technique related to a vertical motor having a rotating rotor therein.

Meanwhile, in the vertical motor, it is necessary to disassemble the rotating rotor mounted in the vertical direction during the disassembly and maintenance, and in the disassembling process, the rotor drawn in the vertical direction connected to the crane should be turned in the horizontal direction. A crane is needed.

Therefore, in the prior art, it is impossible to disassemble and repair the motor at the work site where one crane is installed, so that it is necessary to move the motor to the place where the two crane is installed.

In addition, since it is necessary to cooperate with the two crane operators in order to change the rotor drawn from the motor to the two crane, it takes a long time for maintenance and there is a risk of occurrence of safety accident.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above-mentioned problems in the prior art, and it is an object of the present invention to provide a direction switching device capable of switching the direction of a rotor drawn out from a motor with only one crane, .

In order to achieve the above object, a redirection device of the present invention comprises a lower support, an upper support connected rotatably by a rotary shaft, Wherein the lower support is coupled to the body portion; A shaft-shaft coupling portion is coupled to the upper portion of the upper support; An insertion groove is formed in the shaft shaft coupling portion so that a shaft axis of the rotor drawn out from the vertical motor can be inserted and coupled in a vertical direction; And a moving bogie for seating the rotor when the rotor coupled to the shaft bogie is in a horizontal state.

In the present invention, after the rotor is taken out from the crane, the direction of the rotor is changed to a horizontal shape by using the direction changing device of the present invention, and movement for the maintenance work is possible, so that maintenance work can be performed with only one crane And thus the working efficiency is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 7, a lower support 11 for converting a rotor 1 drawn out from a vertical motor into a horizontal direction is installed in the vertical direction of the rotor 1, And a movable carriage 20 for placing and moving the rotor 1 whose direction has been switched in the horizontal direction.

The lower support 11 and the upper support 12 coupled to the main body 10 are rotatably connected to each other by a rotary shaft 11a. And an insertion groove 13a is formed in the shaft shaft coupling portion 13 so that the shaft shaft 1a of the rotor 1 drawn out from the vertical motor can be inserted and coupled in the vertical direction.

Particularly, the shaft shaft engaging portion 13 is formed with an insertion groove 13a through which the shaft shaft 1a of the rotor 1 can be inserted, and a plurality of A fixing bolt 14 is radially fastened and a pressing plate 14a for pressing and fixing the shaft shaft 1a is formed at the tip of the fixing bolt 14.

A guide groove 10a having a predetermined depth is formed in the body 10 so that the height of the lower support 11 can be adjusted and the lower support 11 is prevented from being separated from the upper part of the body 10. [ And a latching jaw 15 is formed so that the upper support 12 can be hooked in the rotation process.

A rotation support base 16 is formed at one side of the main body 10 so as to support the upper support base 12 rotated 90 degrees with respect to the rotation axis 11a.

On the other hand, in the moving carriage 20, a seat portion 21 for seating the rotor 1 is formed in a curved shape, and a protective layer made of an elastic material for protecting the rotor 1 23 are formed on the lower surface of the base plate 21, and a moving wheel 22 is formed on the lower side.

Reference numeral 12a denotes a key groove in which a fixed key (not shown) can be fastened to prevent rotation of the upper support 12.

Hereinafter, a process of changing the direction of the rotor 1 using the vertical rotor direction changing device of the present invention will be described.

If a vertical motor (not shown) needs to be disassembled and serviced according to the occurrence of a planned preventive maintenance worker or an unexpected situation, after the rotor 1 is taken out of the motor by using a crane, And the lower end of the rotor 1 is engaged with the shaft coupling portion 11.

That is, at this time, the rotor 1 drawn out through the operation of one crane is gradually lowered while being positioned on the upper portion of the direction changing device of the present invention, so that the shaft shaft 1a is seated on the shaft shaft engaging portion 13 Respectively.

The pressing plate 14a presses the shaft shaft 1a using the fixing bolt 14 so that the lower end of the rotor 1 is stably coupled to the shaft shaft engaging part 13. [

Then, when the crane is gradually moved in the horizontal direction, the upper support 12 is supported by the pivot support 16 at the 90 degree position while being rotated around the pivot shaft 11a so that the rotor 1 rotates in the horizontal direction At this time, the body of the rotor 1 is seated on the seat 21 of the moving carriage 20.

The lower support 11 is raised along the guide groove 10a and the upper height of the lower support 11 is lower than the height of the lower portion of the rotor 1, Depending on the size of the diameter.

5 and 6 show a state in which the direction of the rotor is switched. When the direction of the rotor 1 is changed as described above, when the coupling force to the shaft shaft 1a coupled to the shaft shaft coupling portion 13 is released Thereafter, as shown in FIG. 7, the moving carriage 20 is moved to the maintenance place.

Therefore, when the direction changing device of the present invention is used, it is possible to disassemble and move the rotor by only one crane, so that the maintenance work can be performed more easily and safely.

On the other hand, when the rotor 1 having completed maintenance is to be mounted on the motor again, it is coupled to the shaft shaft engaging portion 13 in a state of being horizontally mounted on the moving truck 20 in the reverse order of the above, So that the upper support 12 is maintained in a stable vertical state by inserting the fixing key into the key groove 12a in a state of being turned in the vertical direction.

FIG. 8 shows a cross-sectional structure of a shaft shaft coupling part according to another embodiment of the present invention. It can be seen that a magnet 19 is formed in the insertion groove 13a.

The shaft shaft 1a is inserted into the insertion groove 13a more easily by the magnetic action of the magnet 19 in the process of seating the rotor 1 on the shaft shaft engaging portion 13 So that the rotor can be easily seated.

9 shows a sectional structure of a rotating support according to another embodiment of the present invention. A buffer plate 17 is formed on the rotation support 16, and the buffer plate 17 is fixed to the elastic spring 18 So that it is elastically supported.

In this way, when the direction of the rotor 1 is changed, the shock absorbing plate 17 absorbs the shock of rotation of the shaft shaft engaging portion 11, so that the shaft shaft engaging portion 11 is damaged and noises Can be prevented, thereby showing an advantage that the occurrence of a safety accident can be prevented.
