DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the accompanying drawings.

1 to 4 are views for explaining a wheel heating apparatus according to the present invention. More specifically, FIG. 1 is a view showing a wheel heating apparatus of the present invention, and FIG. 2 is a view showing a wheel and a wheel shaft portion. Fig. 3 is a view showing the support of the wheel heating apparatus of the present invention, and Fig. 4 is a view showing the first 4th link portion and the second 4th link portion of the wheel heating apparatus of the present invention.

1 to 4, the wheel heating apparatus according to the present invention includes a support portion 30, a connection portion 40, and a heating portion 50.

The supporting portion 30 serves to put the wheel and rotate it. The support portion 30 includes a support base 31 and a rotation portion 32.

As shown in FIG. 3, the support base 31 is formed in a hollow cylindrical shape having a side surface, and a protruding portion is provided upwardly, so that the wheel 20 can be placed on the upper end of the protruding portion. The support base 31 is provided with an opening 35 upwardly and the wheel shaft portion 21 of the wheel 20 is inserted when the wheel 20 is mounted on the support base 31.

As shown in Fig. 1, the rotation part 32 is provided at the lower end of the support 31. The rotation unit 32 includes a support plate 33 and a rotation unit shaft 34 that are mounted to mount the support unit 31 thereon. The rotation part 32 is rotated by the following connection part 40. The rotation unit 32 and the support base 31 are coupled by screws and the rotation unit 32 is rotated by the connection unit 40 and the support base 31 rotates in conjunction with the rotation.

The connection unit 40 connects the support unit 30 and the motor unit 10 and transmits the rotational force of the motor unit 10 to the support unit 30. [ The connecting portion 40 includes a first sprocket 41, a second sprocket 42, and a chain 43.

The first sprocket 41 is provided at the upper end of the motor unit 10 and is rotated by the motor unit 10.

The second sprocket (42) is installed in the rotation part (32). The second sprocket 42 is connected to the first sprocket 41 by a chain 43 and rotates together with the first sprocket 41 to rotate the rotation unit 32.

The first rotating plate 60 and the second rotating plate 61 are formed in a disk shape and are horizontally installed to be spaced apart from the motor unit 10. The first rotating plate (60) and the second rotating plate (61) are rotated by the motor unit (10).

The four-bar link portion 70 and the four-bar link portion 71 are formed by combining four bars. The first four-row link portion 70 and the second four-row link portion 71 are installed on the first rotary plate 60 and the second rotary plate 61. The first 4-link section 70 and the second 4-section link section 71 switch the rotational force of the first rotary plate 60 and the second rotary plate 61 to reciprocating motion.

As shown in FIG. 4, the four-bar link used as the first 4-link section 70 and the second 4-section link section 71 includes a fixing section 72, a coupling section 73, 74). The engaging portion 73 is engaged with the first rotating plate 60 and the second rotating plate 61. The fixing portion 72 is fixed and does not move. The fixing portion 72 may be fixed by a separate device. The reciprocating portion 74 is a portion reciprocating by the operation of the four-bar link. When the engaging portion 73 is rotated, the reciprocating portion 74 can reciprocate because the fixing portion 72 is fixed.

Because of the operation of the four-bar link described above, the first 4-link portion 70 and the second 4-row link portion 71 can reciprocate the rotational force of the first rotary plate 60 and the second rotary plate 61 Move to exercise.

The heating unit 50 is installed at one end of the first 4-link unit 70 and the second 4-unit link unit 71 in the direction toward the wheel 20. The heating unit 50 heats the inside and outside of the wheel 20 while reciprocating by the first 4-link unit 70 and the second 4-row link unit 71.

The wheel 20 is heated by the heating unit 50 which reciprocates the upper and lower surfaces of the rotating wheel 20 so that the wheel 20 is removed from the wheel 20, .

Hereinafter, the operation of the wheel heating apparatus according to the present invention having the above-described configuration will be described in detail.

The wheel shaft portion 21 must be separated from the wheel 20 in order to replace a bearing installed inside the wheel 20 of the wheel that rotates on the rail on which the crane is installed. The upper and lower surfaces of the wheel 20 are heated by the heating portion 50 to separate the wheel shaft portion 21 from the wheel 20 in order to separate the wheel 20 and the wheel shaft portion 21, .

First, when the motor unit 10 is operated, the rotating force of the motor unit 10 rotates the rotating unit 32 by the connecting unit 40. When the rotation unit 32 rotates, the support base 31 on the upper end of the rotation unit 32 rotates and the wheel 20 mounted on the upper end of the support base 31 rotates.

When the motor unit 10 is operated, the first rotating plate 60 and the second rotating plate 61 spaced upward from the motor unit 10 are rotated, and the first rotating plate 60 and the second rotating plate 60 The rotational force of the motor unit 10 is converted into a reciprocating motion by the actions of the first 4-link unit 70 and the second 4-unit link unit 71 provided on the rotary plate 61. A heating section 50 installed at one end of the first 4-link section 70 and the second 4-section link section 71 in the direction toward the wheel 20 reciprocates the rotating wheel 20, can do.

When the wheel 20 is heated, the wheel 20 expands, and the wheel 20 and the wheel shaft 21, which are tightly coupled, can be easily separated from each other.

As described above, it is to be understood that the technical structure of the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, All changes or modifications that come within the scope of the equivalent concept are to be construed as being included within the scope of the present invention.
