Description

TECHNICAL FIELD

[0001] The present application relates to the field of mechanical equipment transportation, and in particular to a transportation support for a gear compressor. BACKGROUND

[0002] A gear compressor is a device capable of compressing air, comprising a base and a volute. After being manufactured, the gear compressor first needs to be tested in the factory before being transported by road to the user. A transportation support is usually provided, the base of the gear compressor is installed on the transportation support, and the gear compressor is projected on the ground to fall within the projection range of the transportation support on the ground to prevent the gear compressor from falling over during transportation.

[0003] In the related art, the lower edge of the volute is lower than the base. Therefore, during transportation of the gear compressor, a higher support is usually used to lift the base so that there is a gap between the volute and the table, thereby ensuring that the gear compressor can be placed stably.

[0004] When the gear compressor is transported to the test workshop by the in-plant transportation equipment, the transportation height does not need to be considered, so a higher support can be provided to lift the entire gear compressor, so that each volute has a gap with the table. However, during road transportation after leaving the factory, in order to meet the height requirements of road transportation, the volute with a lower edge lower than the base is usually removed in its entirety, and a lower support is provided to support the base. This easily leads to the support used during in-plant transportation being idle and wasted, and easily leads to the need to reinstall the multiple volutes when installed outside the factory, which is laborious and time-consuming, and increases the transportation cost or installation cost of the gear compressor.

[0026] The transport bracket for a geared compressor provided herein can have a first state and a second state.

In the second state, the main bracket is missing, and the upper side of the base and the lower side of the secondary bracket are directly connected. Therefore, when using the transport bracket provided herein, different states can be selected based on different usage scenarios. For example, when transporting a geared compressor within a factory, the first state can be used, in which the secondary bracket, main bracket, and base are arranged in a vertically arranged sequence and connected in a sequential manner. Because the main bracket is height-adjustable, the transport bracket can be of sufficient height to bridge the first vertical gap between the lower edge of the first volute and the lower surface of the base. Therefore, the first state transport bracket can stably support the entire geared compressor without removing the volute. When the geared compressor needs to be transported outside the factory, the first or second state transport bracket can be selected as needed to support the geared compressor, minimizing the number of volutes that need to be removed, for example, removing only one volute. As can be seen from the above, by providing a detachable main bracket, the transport bracket can be transformed between the first state and the second state. Therefore, when the gear compressor is transported within the factory, the volute does not need to be removed. When transported outside the factory, the number of volutes to be removed can be selected according to demand, thereby reducing the production cost caused by removing the volute. Moreover, the disassembled main bracket can be used on other transport brackets for transportation within the factory, achieving reuse, which is conducive to reducing the production cost of the gear compressor.

Figures 6 to 8 A schematic view of the transport support in the first state when the gear compressor is installed thereon. Figures 9 to 11 A schematic view of the transport support in the second state when the gear compressor is installed thereon.

[0047] With reference to Figures 6 to 8 , the gear compressor can include a base 91, a main body 92 and a volute, the main body 92 and the base 91 are distributed along the up-down direction, the lower end of the base 91 and the main body 92 are connected, and the volute and the main body 92 are connected. The volute can include a first volute 931, a second volute 932 and a third volute 933. Obviously, the lower end edge of the first volute 931 and the lower end edge of the second volute 932 are located below the base 91, and the third volute 933 is located above the base 91. The first volute 931 and the second volute 932 are respectively located on both sides of the main body 92, and the first volute 931 and the third volute 933 are located on the same side of the main body 92. The first spacing between the lower end edge of the first volute 931 and the base in the up-down direction is greater than the second spacing between the lower end edge of the second volute 932 and the base in the up-down direction. The upper end edge of the third volute 933 is located above the lower surface of the base.

[0048] With reference to Figure 1 and Figure 4 , the present application provides a transport support for a gear compressor, when the transport support carries the gear compressor, the transport support and the gear compressor are distributed along the up-down direction, and the transport support is located below the gear compressor.

[0049] The transport support provided by the present application includes a sub-support 30, a main support 20 and a base 10, the sub-support 30 and the main support 20 are detachably connected, the main support 20 and the base 10 are detachably connected, and the sub-support 30 and the base 10 can be directly detachably connected when the main support 20 is missing; the sub-support 30 is used for installing the base of the gear compressor.

[0050] From the above technical solution, the transport support can have a first state and a second state, in the first state, with reference to Figure 1 , the sub-support 30, the main support 20 and the base 10 are sequentially distributed along the up-down direction, and the main support 20 is connected between the base 10 and the sub-support 30. In the second state, with reference to Figure 2, the upper side of the base 10 and the lower side of the auxiliary support 30 can be directly connected. Therefore, when the transport support provided by the present application is used, different states of the transport support can be selected according to different use scenarios. For example, when the transport support is used to transport the gear compressor in the factory, referring to Figures 6 to 8 , the first state of the transport support can be used, that is, the auxiliary support 30, the main support 20 and the base 10 are distributed along the up-down direction and are sequentially connected. Since the height of the main support 20 is adjustable, the transport support can have sufficient height to compensate for the first spacing in the up-down direction between the lower end edge of the first volute 931 and the lower surface of the base 91, so that the first state of the transport support can stably support the entire gear compressor without the need to disassemble the volute. When the gear compressor needs to be transported outside the factory, the first state or the second state of the transport support can be selected for use to support the gear compressor according to the needs, so as to minimize the number of volutes to be disassembled, for example, only one volute is disassembled.

[0051] As can be seen from the above, by providing the detachable main support 20, the transport support can be changed between the first state and the second state, so that when the gear compressor is transported in the factory, the volute does not need to be disassembled, and when the gear compressor is transported outside the factory, the number of volutes to be disassembled can be selected according to the needs, thereby reducing the production cost caused by disassembling the volute. Moreover, the disassembled main support 20 can also be applied to other transport supports for transporting in the factory, so as to realize recycling and reduce the production cost of the gear compressor.

[0052] In a possible embodiment, when the auxiliary support 30 and the base 10 are directly detachably connected, the sum of the heights of the auxiliary support 30 and the base 10 in the up-down direction is greater than the second spacing and less than the first spacing. In other words, the height of the second state of the transport support can be designed to compensate for the second spacing in the up-down direction between the lower end edge of the second volute 932 and the lower surface of the base 91, so that referring to Figures 9 to 11 , only the first volute 931 needs to be disassembled, and the second state of the transport support can be used to stably support the gear compressor, further reducing the volutes to be disassembled when transported outside the factory, so that after the gear compressor is installed, the number of volutes to be installed can be reduced, which is conducive to reducing the cost of disassembling and assembling the volute.

[0053] When the transport support carries the gear compressor, the orthographic projection of the gear compressor on a virtual plane perpendicular to the up-down direction falls within the orthographic projection range of the base 10 on the virtual plane. In this way, the base 10 of the transport support has a large size and can stably support the gear compressor to prevent the gear compressor from falling over.

[0054] In a specific implementation, the transport bracket further comprises a first connecting structure 41, a second connecting structure 42, and a third connecting structure 43, the first connecting structure 41 and the second connecting structure 42 are adapted, the third connecting structure 43 is adapted to the base of the gear compressor, the third connecting structure 43 is arranged on the upper side of the auxiliary bracket 30 for mounting the base of the gear compressor; the second connecting structure 42 is arranged on the lower side of the auxiliary bracket 30, and the first connecting structure 41 is arranged on the upper side of the main bracket 20, so that the auxiliary bracket 30 and the main bracket 20 are detachably connected; the second connecting structure 42 is arranged on the lower side of the main bracket 20, and the first connecting structure 41 is arranged on the upper side of the base 10, so that the main bracket 20 and the base 10 are detachably connected, and so that the lower side of the auxiliary bracket 30 and the upper side of the base 10 can be directly detachably connected when the main bracket 20 is missing; the height of the main bracket 20 in the up-down direction is adjustable. In other words, the detachable connection between the lower side of the auxiliary bracket 30 and the upper side of the main bracket 20 can be achieved by the first connecting structure 41 and the second connecting structure 42, the detachable connection between the lower side of the main bracket 20 and the upper side of the base 10 can be achieved, and the lower side of the auxiliary bracket 30 and the upper side of the base 10 can be directly detachably connected.

[0055] In a possible implementation, referring to Figure 1 , the main bracket 20 comprises a bracket unit 21, the upper and lower sides of the bracket unit 21 are respectively provided with a first connecting structure 41 and a second connecting structure 42, the number of the bracket unit 21 is one or more, when the number of the bracket unit 21 is more, the plurality of bracket units 21 are stacked in the up-down direction, and the adjacent two bracket units 21 are detachably connected through the first connecting structure 41 and the second connecting structure 42. In this way, the height of the main bracket 20 in the up-down direction can be determined by the number of the bracket units 21 included in the main bracket 20. That is, in actual use, different numbers of bracket units 21 can be stacked in the up-down direction to achieve different heights, thereby achieving the height adjustment of the main bracket 20.

[0056] In a specific implementation, referring to Figure 1 , the bracket unit 21 can comprise two carriers 211, the two carriers 211 are parallel and spaced apart, and the upper and lower sides of the carrier 211 are respectively provided with a first connecting structure 41 and a second connecting structure 42; the upper side of the base 10 is provided with two first connecting structures 41 to connect with the lower sides of the two carriers 211 of the bracket unit 21. In this way, the support unit can stably support the auxiliary bracket 30 through the two carriers 211, and further stably support the gear compressor.

[0057] In an example, referring to Figure 4The carrier 211 comprises an upper horizontal plate 2111, a support plate 2113 and a lower horizontal plate 2112, the upper horizontal plate 2111 and the lower horizontal plate 2112 are parallel, and the support plate 2113 is connected between the upper horizontal plate 2111 and the lower horizontal plate 2112; the first connecting structure 41 is arranged on the upper horizontal plate, and the second connecting structure 42 is arranged on the lower horizontal plate.

[0058] In an example, with reference to Figure 5 The carrier 211 further comprises a reinforcing rib 212, the reinforcing rib 212 is connected between the upper horizontal plate 2111 and the lower horizontal plate 2112, and the reinforcing rib 212 is symmetrically distributed about the support plate 2113. In an embodiment, the reinforcing rib 212 can be a plate structure and is perpendicular to the support plate 2113.

[0059] In a possible embodiment, with reference to Figure 3 The auxiliary support 30 comprises a first connecting rod 31 and a second connecting rod 32, the number of the first connecting rod 31 is two, and the first connecting rods 31 are parallel and spaced apart, and the second connecting rod 32 is connected between the two first connecting rods 31; the upper side and the lower side of the first connecting rod 31 are respectively provided with the third connecting structure 43 and the second connecting structure 42; the upper sides of the two first connecting rods 31 are connected with the base of the gear compressor, and the two first connecting rods 31 and the two carriers 211 of the support unit 21 are connected one by one. That is, the upper side of the first connecting rod 31 is provided with the third connecting structure 43 to be connected with the base of the gear compressor, and the lower side of the first connecting rod 31 is provided with the second connecting structure 42 to be connected with the first connecting structure 41 on the upper side of the carrier 211. In this way, the transportation support structure is stable and can stably carry the gear compressor.

[0060] In a possible embodiment, with reference to Figure 2 The base 10 comprises a horizontal rod 12, a vertical rod 13 and a frame 11, the vertical rod 13 is provided with the first connecting structure 41, the horizontal rod 12 and the vertical rod 13 are surrounded by the frame 11 and connected with the frame 11, and the horizontal rod 12 and the vertical rod 13 are connected with each other. In this way, the frame 11 is arranged to strengthen the structural strength and facilitate transportation.
