Description

Technical Field

[0001] This utility model relates to the field of compressor testing technology, and in particular to a universal compressor test bench. Background Technology

[0002] Large, heavy-duty compressors are tested on test stands erected at high positions. These stands are typically constructed using square boxes and long beams. Due to the large size and weight of the compressors, a large number of square boxes and long beams are required. During construction, the compressor's center height and position must be constantly adjusted, resulting in significant time and labor demands for each test stand setup. After the unit's testing is complete, the square boxes and long beams of the test stand need to be dismantled, an effort equivalent to the construction work. After dismantling, the square boxes and long beams create a cluttered site. When other compressors need testing, the square boxes and long beams must be re-laid and re-erected, adding to the workload. This repeated laying and dismantling of the test stand increases worker workload and consumes valuable testing time. Utility Model Content

[0037] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of a universal compressor stand proposed according to this utility model.

[0038] like Figure 1-3 As shown, this utility model embodiment provides a universal compressor stand for supporting a compressor. The compressor (10) includes a housing, and a connecting claw (20) is connected to the housing. The universal compressor stand includes:

[0039] Front crossbeam (100), rear crossbeam (200), outriggers (300) and raised platform (400);

[0040] The front crossbeam (100) and the rear crossbeam (200) are arranged in the first direction. Two support legs (300) are connected to the front crossbeam (100) and the rear crossbeam (200) respectively. A raised box (400) is connected above the support leg (300). The raised box (400) is used to connect with the connecting claw (20).

[0041] The structure of the compressor (10) is as follows Figure 1-3 The image is shown in the dashed line. The compressor (10) includes a housing and a rotor assembly passing through the housing. The rotor assembly includes a shaft and blades, with the axial direction of the shaft as the first direction. Two connecting claws (20) are respectively provided on the housing at the front and rear ends near the axial direction. The bottom of the connecting claws (20) includes a connecting plate, which has a flat surface facing the bottom. The housing includes an air inlet and a volute, etc. Figure 1 As shown, the air inlet is located at the bottom and requires a certain amount of space. At the point of use, the compressor universal stand is installed on existing floor rails. There are usually two floor rails, laid parallel to each other at intervals, used to secure the compressor universal stand.

[0042] The front crossbeam (100) and rear crossbeam (200) are the bottom support components of the compressor universal frame. The front crossbeam (100) and rear crossbeam (200) can be fixed to the ground rail with bolts or the like. The ground rail is provided with multiple fixing holes extending in the first direction. The fixing holes can be slotted holes, so that the front crossbeam (100) and rear crossbeam (200) can be fixed in various positions in the first direction as needed, and the spacing between the front crossbeam (100) and rear crossbeam (200) is adjustable. This allows for the adaptation to the position of the connecting claw (20) of various compressors, as well as the required space occupied by the air inlet and volute of the connecting claw (20).

[0043] The outriggers (300) primarily serve to elevate and adjust the position of the support box (400). The relative positions of the outriggers (300) when connected to the front crossbeam (100) and when connected to the rear crossbeam (200) are adjustable. In other words, the positions of the outriggers (300) relative to the front crossbeam (100) and relative to the rear crossbeam (200) in the first direction and perpendicular to the first direction are adjustable. This allows for flexible adjustment based on the position of the connecting claws (20), achieving the universality of the compressor universal stand. The position adjustment method will be further described in detail in the following embodiments.

[0044] The elevation box (400) serves to adjust the height. Multiple elevation boxes (400) can be used, and they can be a series of sets. Elevation boxes (400) of different heights can accommodate different compressor mounting heights. For example, if the air inlet channel is long and the compressor needs to be mounted higher, a higher elevation box (400) can be used. Furthermore, the relative position of the elevation box (400) and the support leg (300) is adjustable, allowing for further adjustments based on the needs of the connected compressor, thus achieving the versatility of the platform.

[0045] When in use, adjust the position of the outrigger (300) and the shim box (400), and hoist the compressor so that the connecting claw (20) is opposite to the shim box (400). During this process, the position of the outrigger (300) and the shim box (400) can be adjusted until the connecting claw (20) and the shim box (400) can be accurately aligned. Then fix the connecting plate of the connecting claw (20) and the shim box (400).

[0046] The universal compressor test bench proposed in this embodiment mainly utilizes the configuration of a front crossbeam, a rear crossbeam, support legs, and a raised platform. The position of the support legs on the front and rear crossbeams can be adjusted as needed, and the specifications of the raised platform can be selected accordingly. This allows it to be applicable to various compressors and can be adjusted according to the different compressors being tested, eliminating the need for disassembly and reconstruction each time. This significantly shortens the time required for setting up the test bench, reduces the labor intensity of workers, and greatly improves the efficiency and quality of the test bench installation for high-position compressors. It also improves the aesthetics and tidiness of the workshop. Furthermore, the spacing between the front and rear crossbeams allows for space to be provided for the air outlet flanges and volute flanges of large, heavy-duty compressors.

[0047] In one implementation, such as Figure 4-6 As shown, the front crossbeam (100) includes a first intermediate region (101) and two first outer regions (102), the two first outer regions (102) being located on both sides of the first intermediate region (101) perpendicular to the first direction, and the extension width of the first intermediate region (101) in the first direction being smaller than the extension width of the first outer regions (102) in the first direction.

[0048] like Figure 7-9 As shown, the rear crossbeam (200) includes a second intermediate region (201) and two second outer regions (202), the two second outer regions (202) being located on both sides of the second intermediate region (201) perpendicular to the first direction, and the extension width of the second intermediate region (201) in the first direction being smaller than the extension width of the second outer regions (202) in the first direction.

[0049] Both the front crossbeam (100) and the rear crossbeam (200) have a structure that is narrower in the middle in the first direction and wider at both ends. This design accommodates the compressor's air vents, volute, etc., while also providing sufficient support strength and connection area with the support legs (300) to ensure the stability of the connection with the support legs (300). The two first outer regions (102) can be symmetrically arranged relative to the first middle region (101), and the two second outer regions (202) can be symmetrically arranged relative to the second middle region (201).

[0050] In one implementation, such as Figure 4-6 As shown, the front crossbeam (100) includes a front top plate (110), a front intermediate beam (120), and a front bottom plate (130). The front top plate (110) and the front bottom plate (130) are arranged parallel to each other in the vertical direction. The front intermediate beam (120) is located between the front top plate (110) and the front bottom plate (130) and extends in a direction perpendicular to the first direction. The front top plate (110) is connected to the support leg (300). The front intermediate beam (120) is a single beam.

[0051] The connection method of the front top plate (110), the front intermediate beam (120), and the front bottom plate (130) can ensure structural strength while reducing the weight of the front crossbeam (100). The front top plate (110) and the front bottom plate (130) are both laid horizontally and have a structure that is narrower in the middle and wider at both ends in the first direction. The front top plate (110) and the front bottom plate (130) can have the same shape, or the front bottom plate (130) can be wider in the first direction than the front top plate (110) in the first outer area (102), so that it can be easily connected to the ground rail. The front intermediate beam (120) is a strip beam set vertically to the horizontal plane. By using a single front intermediate beam (120), the width of the first intermediate area (101) can be made very small, so as to effectively make way for the compressor air outlet, etc., especially for compressors with a small distance between the volute and the air outlet. In addition, the front crossbeam (100) may also include multiple front reinforcing ribs (140), which are located in the two first outer regions (102) and can be arranged in a crisscross pattern. They can also be arranged close to the front top plate (110) at the edge of the first outer region (102) to better reinforce the strength between the front top plate (110) and the front bottom plate (130) and increase the support strength of the compressor.

[0052] like Figure 7-9As shown, the rear crossbeam (200) includes a rear top plate (210), at least two rear intermediate beams (220), and a rear bottom plate (330). The rear top plate (210) and the rear bottom plate (230) are arranged parallel to each other in the vertical direction. The rear intermediate beams (220) are located between the rear top plate (210) and the rear bottom plate (230) and extend in a direction perpendicular to the first direction. The rear top plate (210) is connected to the support leg (300). At least two rear intermediate beams (220) are arranged parallel to each other.

[0053] By employing a connection method consisting of a rear top plate (210), at least two rear intermediate beams (220), and a rear bottom plate (330), structural strength can be ensured while reducing the weight of the rear crossbeam (200). Both the rear top plate (210) and the rear bottom plate (330) are laid horizontally and have a structure that is narrower in the middle and wider at both ends in the first direction. The rear top plate (210) and the rear bottom plate (330) can have the same shape, or the rear bottom plate (330) can be located in the second outer region (202) with a width greater than that of the rear top plate (210) in the first direction, thus facilitating connection to the ground rail. The rear intermediate beams (220) are strip beams set vertically to the horizontal plane. Because the rear crossbeam (200) houses the compressor and gearbox in the test foundation layout, it bears a heavy load. To improve its strength, multiple rear intermediate beams (220) are installed, such as two rear intermediate beams (220), to ensure sufficient strength for the rear crossbeam (200). In addition, the rear crossbeam (200) may also include multiple rear reinforcing ribs (240). The rear reinforcing ribs (240) are located in the two second outer regions (202) and can be arranged in a crisscross pattern. They can also be placed close to the rear top plate (210) at the edge of the second outer region (202) to better reinforce the strength between the rear top plate (210) and the rear bottom plate (330), thereby increasing the support strength of the compressor.

[0054] In one implementation, such as Figure 4-12 As shown, both the front crossbeam (100) and the rear crossbeam (200) are provided with a plurality of first T-slots (103), which extend perpendicular to a first direction. The support leg (300) is provided with at least one first oblong hole (301), which extends in the first direction. The compressor universal frame also includes first T-bolts for fixing the support leg (300) through the first T-slots (103) and the first oblong holes (301).

[0055] Multiple first T-slots (103) are provided on the front crossbeam (100) and the rear crossbeam (200), and each leg (300) corresponds to multiple first T-slots (103). For example, on the front crossbeam (100), multiple parallel and spaced first T-slots (103) are provided in the two first outer regions (102), and on the rear crossbeam (200), multiple parallel and spaced first T-slots (103) are provided in the two second outer regions (202). The first T-slot (103) is a strip-shaped groove with a smaller opening width at the top and a larger width near the bottom, and one end of the first T-slot (103) is open. The nut of the first T-bolt is adapted to the contour of the first T-slot (103). The nut of the first T-bolt is inserted into the first T-slot (103) through one end opening. The screw passes through the top opening of the first T-slot (103) and through the first waist-shaped hole (301), and is then tightened by the nut. By adjusting the position of the first T-bolt in different positions within the first T-slot (103), connecting to different first T-slots (103), and adjusting the position of the first T-bolt within the first waist-shaped hole (301), the position of the support leg (300) can be flexibly adjusted, thereby adapting to different compressors.

[0056] In some implementations, such as Figure 10-12 As shown, the outrigger (300) includes an outrigger base plate, a support frame and an outrigger top plate. The outrigger base plate and the outrigger top plate are horizontally spaced apart. The support frame is located in front of the outrigger base plate and the outrigger top plate and serves to support the outrigger top plate. The aforementioned first waist-shaped hole (301) is opened on the outrigger base plate.

[0057] In one implementation, such as Figure 10-14 As shown, the support leg (300) is provided with a plurality of second T-slots (302). The second T-slots (302) extend perpendicular to the first direction, and the raised platform (400) is provided with at least one second oblong hole (401), which extends in the first direction. The compressor universal platform also includes second T-bolts for fixing the raised platform (400) through the second T-slots (302) and the second oblong hole (401).

[0058] like Figure 13-14 As shown, the raised platform (400) can be a four-sided frame structure. The structure and interaction of the second T-slot (302), the second oblong hole (401), and the second T-bolt can be found in the description of the first T-slot (103), the first oblong hole (301), and the first T-bolt, and will not be repeated here. The second T-slot (302) is located on the top plate of the support leg. This configuration allows for flexible adjustment of the raised platform (400) to accommodate different compressors.

[0059] In one embodiment, there are multiple raised boxes (400), which are divided into multiple groups, each group including four raised boxes (400). The raised boxes (400) in the same group have the same structure, and the raised boxes (400) in different groups have at least different heights.

[0060] That is, there are at least four raised boxes (400) of the same specification, which in turn provide equal support for the four connecting claws (20). By providing raised boxes (400) of different specifications, different support height requirements can be met. Raised boxes (400) of different specifications can be raised boxes (400) of different heights, or raised boxes (400) of different heights, lengths, and widths.

[0061] In one embodiment, both the front crossbeam (100) and the rear crossbeam (200) are provided with a third waist-shaped hole (104), which is used to connect the ground rail.

[0062] The connecting bolts can be threaded through the third oblong hole (104) and the fixing hole on the ground rail, and then fixed with nuts. The third oblong hole (104) allows for more flexible adjustment of the spacing between the front crossbeam (100) and the rear crossbeam (200).

[0063] In one embodiment, the front crossbeam (100), rear crossbeam (200), outriggers (300), and raised platform (400) are all formed by welding sheet metal.

[0064] In the aforementioned embodiments, the front top plate (110), front middle beam (120), front bottom plate (130) and front reinforcing rib (140) included in the front crossbeam (100) are all plate structures, which can be formed by direct CNC blanking. After blanking, welding can be carried out directly without processing, which is quick, saves processing time, and improves the efficiency of bench processing.

[0065] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
