[0009] Hereinafter, the embodiments will be described with reference to the drawings. In each drawing, the same reference numerals are used to denote common or corresponding elements, and the description is simplified or omitted. The configurations shown in the embodiments below are examples of the technical ideas related to the present disclosure, and may be combined with other known technologies, or multiple technical ideas described in the present disclosure may be combined. In addition, it is also possible to omit or modify a part of the configuration without departing from the gist of the present disclosure.

[0010] Embodiment 1 1 and 2 are perspective views of a lifting tool 1 for draining compressor oil according to embodiment 1. As shown in Fig. 1 and 2, the lifting tool 1 for draining compressor oil in this embodiment includes a compressor upper lifting part 2 for lifting an upper part of a compressor 10, a compressor lower lifting part 3 for lifting a lower part of the compressor 10, and a tower 4 for supporting the compressor upper lifting part 2 and the compressor lower lifting part 3.

[0011] The compressor upper lifting part 2 has a lifting part connection part 5 that is connected to the lifting part 11 on the upper part of the compressor 10. The compressor lower lifting part 3 has a base connection part 6 that is connected to the base 12 of the compressor 10. In this embodiment, by providing the compressor upper lifting part 2 and the compressor lower lifting part 3, it is possible to tilt the compressor 10 and lift it. In the illustrated example, the lifting part connection part 5 and the base connection part 6 are each a hook-shaped member.

[0012] The tower 4 comprises four pillars 7, four cross members 8, and three beam members 9. The four pillars 7 are arranged at the four corners of a rectangle in plan view. Each of the four cross members 8 connects the upper parts of two adjacent pillars 7 out of the four pillars 7. The four cross members 8 are arranged in the shape of a rectangular frame.

[0013] Each of the three beam members 9 leaves one side of the rectangle as an opening 13, and connects the lower parts of two adjacent columns 7 of the four columns 7 to the other three sides. In the illustrated example, the beam members 9 connect the lowermost parts of the columns 7 and are grounded. This allows workers to enter the inside of the tower 4, facilitating the work of connecting the lifting part connection part 5 and the base connection part 6 to the lifting part 11 and base 12 of the compressor 10. The three beam members 9 are arranged in a U-shape.

[0014] Each of the pillars 7, the cross members 8, and the beam members 9 is made of a member having an L-shaped cross section. A large number of long holes are formed in each of the pillars 7, the cross members 8, and the beam members 9, which contributes to weight reduction.

[0015] The compressor upper lifting weight section 2 is supported by a cross member 8 above the opening 13. The compressor lower lifting weight section 3 is supported by a cross member 8 on the opposite side of the cross member 8 above the opening 13.

[0016] 3 is a perspective view showing a state in which the dolly 90 is carried into the tower 4. In this embodiment, by providing the opening 13 without the beam member 9, the dolly 90 can be carried into the tower 4, and therefore the compressor 10 can be placed on the dolly 90 and carried into the tower 4.

[0017] Fig. 4 is a perspective view showing the compressor 10 placed on a cart 90 and carried into the tower 4. Fig. 4 shows the state in which the lifting part connection part 5 of the compressor upper lifting part 2 is connected to the lifting part 11 at the top of the compressor 10. The compressor 10 has a cylindrical main body with a central axis parallel to a vertical line.

[0018] Fig. 5 is a perspective view showing a state in which the compressor 10 is placed on a dolly 90 and carried into the tower 4. Fig. 5 shows a state in which the pedestal connection part 6 of the compressor lower lifting part 3 is connected to the pedestal 12 at the lower part of the compressor 10.

[0019] Each of the compressor upper lifting unit 2 and the compressor lower lifting unit 3 has an operating unit. In the illustrated example, the compressor upper lifting unit 2 and the compressor lower lifting unit 3 are chain blocks, and the operating units are composed of chains. The operating units of the compressor upper lifting unit 2 and the compressor lower lifting unit 3 are located above half the height of the support 7. This allows an operator to easily operate the operating units of the compressor upper lifting unit 2 and the compressor lower lifting unit 3 while standing.

[0020] 6, 7, and 8 are perspective views showing a state in which the compressor 10 is lifted by the compressor upper lifting part 2 and the compressor lower lifting part 3 so that the compressor 10 is tilted with the port of the compressor 10 facing downward. As shown in these figures, the compressor oil draining lifting tool 1 is provided with an oil receiving part 14 that receives oil flowing out from the port of the compressor 10, and a splash prevention part 15. The oil receiving part 14 is disposed inside the space formed by the four pillars 7 of the tower 4. The splash prevention part 15 is disposed between the floor surface and the oil receiving part 14. The splash prevention part 15 prevents the floor from being stained with oil. The splash prevention part 15 may be, for example, cardboard. The oil receiving part 14 in the illustrated example is an oil pan. The oil receiving part 14 is not limited to the illustrated example, and may be a funnel-shaped member connected to a pipe.

[0021] The method for draining compressor oil in this embodiment includes the steps of loading the compressor 10 onto a cart 90 and transporting it in, attaching the lifting part connection part 5 of the compressor upper lifting part 2 to the lifting part 11 at the top of the compressor 10, attaching the base connection part 6 of the compressor lower lifting part 3 to the base 12 at the bottom of the compressor 10, lifting the compressor 10 using the compressor upper lifting part 2 and the compressor lower lifting part 3 so that the compressor 10 is tilted with the port of the compressor 10 facing down, and receiving the oil flowing out from the port of the compressor 10 in the oil receiving part 14.

[0022] According to this embodiment, the refrigeration oil can be easily and safely drained from inside the compressor 10. Furthermore, the work can be performed by one person.

[0023] As shown in Fig. 8, it is desirable that the distance L1 between the support pillar 7 connected to the cross member 8 supporting the compressor upper lifting unit 2 and the support pillar 7 connected to the cross member 8 supporting the compressor lower lifting unit 3 be greater than the height of the compressor 10. This allows the compressor 10 to be lifted more stably.

[0024] It is desirable that the distance L2 (see FIG. 1) between the columns 7 in the direction perpendicular to the distance L1 is greater than the distance L1, which makes it possible to more reliably secure a space for the carriage 90 to enter.

[0025] As shown in Fig. 1, the tower 4 in this embodiment has outrigger parts 16 that protrude from both ends of the side opposite the opening 13 toward the opposite side of the opening 13. This improves stability when the compressor 10 is lifted.

[0026] Moreover, the tower 4 in this embodiment is provided with a brace section 17 provided between the cross member 8 above the opening 13 and the support column 7 connected to the cross member 8. This makes it possible to more reliably maintain the distance between the support columns 7 located at both ends of the opening 13 where there are no beam members 9.

[0027] The base connection part 6 connected to the base 12 of the compressor 10 may support the base 12 at two points. With the base connection part 6 supporting the base 12 at two points, the port of the compressor 10 faces more directly downward, which is more advantageous in discharging the refrigeration oil without leaving any residue.

[0028] Fig. 9 is a perspective view showing the state when the lifting tool for draining compressor oil 1 is not in use. As shown in Fig. 9, when the lifting tool for draining compressor oil 1 is not in use, objects can be placed inside the tower 4, which has the advantage that the lifting tool for draining compressor oil 1 does not take up space.

[0029] Although the embodiment has been described above, the lifting tool for draining compressor oil of the present disclosure is not limited to the illustrated example. For example, in the illustrated example, the four support columns 7 are arranged at the four corners of a rectangle in a plan view, but the present disclosure is not limited to this, and the four support columns 7 may be arranged at the four corners of a trapezoid in a plan view.

[0030] Furthermore, the lifting tool for removing compressor oil according to the present disclosure may be equipped with a heating device for warming the compressor 10. By warming the compressor 10, the viscosity of the refrigeration oil decreases, allowing the refrigeration oil to be removed in a short period of time.

[0031] In addition, the lifting tool for draining compressor oil of the present disclosure may be equipped with an automatic lifting device that automatically lifts the compressor 10 so that the inclination angle and lifting height of the compressor 10 are appropriate angles and heights.
