It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0037] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0038] Please refer to Figure 1This embodiment provides a compressor bracket 10 for mounting a compressor 20 , including a base plate 100 and a plurality of pillars 200 .

[0039] The pillars 200 are all disposed on the base plate 100 and extend along a preset direction;

[0040] The support column 200 is used for detachably connecting with the compressor 20. Each support column 200 is provided with a matching portion for connecting with the compressor 20.

[0041] The compressor 20 is an important part of the air conditioning system. The compressor 20 of the hydraulic excavator is fixed to the engine through a bracket. Although it is a small component, it plays an important role. When designing the compressor bracket 10, the simplicity and rationality of the structure should be fully considered. Reasonable design can improve the convenience of the process and the efficiency of assembly.

[0042] However, the existing brackets are inconvenient to operate, specifically:

[0043] 1. The threaded hole on the bracket bottom plate 100 for mounting the compressor 20 shrinks after the sleeve is welded, and needs to be re-tapped, which increases the process.

[0044] 2. The bolts for installing the compressor 20 are relatively long, and it is inconvenient to connect the bolts with the holes during assembly.

[0045] 3. The tensioning device is complicated.

[0046] Accordingly, the compressor bracket 10 of the present solution includes a base plate 100 and a support column 200. By arranging the support column 200 on the base plate 100, the connection method between the compressor 20 and the support column 200 avoids the deformation of the threaded hole on the base plate 100 in the prior art, and the extended support column 200 can shorten the length of the bolt, which is convenient for docking installation. Such a compressor bracket 10 has a simple structure and is easy to operate, and can significantly improve the installation efficiency.

[0047] As can be seen from the figure, a plurality of through holes are provided on the bottom plate 100 .

[0048] Please continue to refer to Figures 1 to 5 , for more structural details.

[0049] In this embodiment of the present invention, the compressor 20 is bolted to the mating part. Bolt connection has the advantages of simple structure, convenient operation, and bolts are universal parts, convenient accessories, and controllable costs. It is also relatively convenient to transform based on existing technologies. It should be noted that in other embodiments of the present invention, the compressor 20 and the bracket can also be connected by snap-on, sleeve-on, etc., as long as the compressor 20 and the support 200 are detachably connected. This is just an example and is not limited.

[0050] Further, from Figure 2 and4 It can be seen that in this embodiment, the matching portion is a mounting hole 201 extending along the height direction of the pillar 200, and the bottom of the mounting hole 201 has a preset distance from the base plate 100; the inner wall of the mounting hole 201 is provided with an internal thread, and the compressor 20 is connected to the pillar 200 through the internal thread.

[0051] Optionally, the depth of the mounting hole 201 is greater than the distance between the bottom of the mounting hole 201 and the bottom plate 100, so as to ensure the stable connection between the compressor 20 and the support 200 and prevent them from being separated. The internal thread here extends along the depth of the mounting hole 201 to form a fully threaded inner wall, thereby ensuring the stability of the connection.

[0052] It can also be seen from the figure that in this embodiment of the present invention, the pillars 200 all extend in the radial direction of the compressor 20. When the compressor 20 is connected to multiple pillars 200, the radial direction of the compressor 20 is the same as the extension direction of the pillars 200. That is, the pillars 200 are installed with compression along the radial direction of the cylinder of the compressor 20. Further, the pillars 200 are vertically arranged on the base plate 100, the extension direction of the cylinder of the compressor 20 is parallel to the base plate 100, and the cylinder is horizontally connected to the pillars 200. Such a connection method can make the compressor 20, the tension wheel 30 and the engine work conveniently.

[0053] It should be noted that, in other embodiments of the present invention, the support 200 and the compressor 20 may be connected in other ways, such as being connected along the compression height direction. This is only an example and is not limiting.

[0054] In this embodiment, a plurality of pillars 200 are arranged in a rectangular shape on the bottom plate 100. Optionally, the compressor bracket 10 includes four pillars 200, the heights of the four pillars 200 are the same, and the four pillars 200 are divided into two groups along the height direction of the bottom plate 100. The distance between the two pillars 200 in each group is the same, and the two groups of pillars 200 are aligned in a rectangular arrangement along the height direction (that is, the distance between the two adjacent groups is greater than the distance between the two pillars 200 in each group). In this way, the compressor 20 can be stably supported and more closely connected to the bottom plate 100.

[0055] It should be noted that the rectangular arrangement of the pillars 200 here is only an example. In other embodiments of the present invention, the pillars 200 may also be arranged in other forms, such as square, diamond, etc., which is not limited here.

[0056] In this embodiment of the present invention, the compressor bracket 10 further includes a mounting plate 300, which is disposed on the other side of the bottom plate 100 away from the pillar 200; the mounting plate 300 is provided with a long strip-shaped adjustment slot 301, which is used to cooperate with the rotating shaft 31 of the tension wheel 30. The adjustment slot 301 is used to cooperate with the tension wheel 30, thereby facilitating the installation of the tension wheel 30 and improving the function of the compressor bracket 10.

[0057] Furthermore, the extending direction of the adjusting slot 301 forms a preset angle with the plane of the bottom plate 100. In this embodiment, the extending direction of the adjusting slot 301 forms an acute angle with the plane of the bottom plate 100. That is, from the top to the bottom of the bottom plate 100, the extending direction of the adjusting slot 301 gradually increases in distance from the bottom plate 100.

[0058] The rotating shaft 31 of the tension wheel 30 is inserted into the adjusting slot 301 , and the extending direction of the rotating shaft 31 and the adjusting slot 301 remain perpendicular.

[0059] Furthermore, the compressor bracket 10 also includes a transition plate 400, and a bending portion 420 is formed at the top of the transition plate 400. The mounting plate 300 is arranged on the bottom plate 100 through the transition plate 400. As can be seen from the figure, a notch 101 is provided at one end of the top of the bottom plate 100; the transition plate 400 is a rectangular plate member, which includes a plate body 410 and a bending portion 420 formed by bending at one end of the plate body 410. The plate body 410 is arranged on the back side of the bottom plate 100 away from the pillar 200 along the height direction of the bottom plate 100, and the bending portion 420 and the bending portion of the plate body 410 are located at the edge of the notch 101, and the bending portion 420 extends from the notch 101 to the side of the bottom plate 100 having the pillar 200.

[0060] The mounting plate 300 is disposed on the transition plate 400 along the extension of the plate body 410 and the bending portion 420 , and the extension direction of the adjustment slot 301 is consistent with the extension direction of the bending portion 420 .

[0061] Such a configuration makes full use of the space of the base plate 100 , thereby ensuring the smooth installation of the compressor 20 and providing support for adjusting the tilt setting of the through slot 301 .

[0062] It can also be seen from the figure that in this embodiment of the present invention, an adjusting member 32 is also included, the mounting plate 300 includes a flat plate 310 with a preset angle and a mounting portion 320, the adjusting slot 301 is located on the flat plate 310, and a matching through hole 321 is provided on the mounting portion 320; the adjusting member 32 passes through the matching through hole 321 and is threadedly connected to the matching through hole 321, and the end of the adjusting member 32 is connected to the rotating shaft 31 of the tensioning wheel 30.

[0063] Specifically, the mounting plate 300 includes a flat plate 310 and a mounting portion 320. The flat plate 310 is vertically arranged on the plate body 410 and the bent portion 420 of the transition plate 400, that is, the flat plate 310 is perpendicular to the base plate 100; and the top height of the flat plate 310 is less than the height of the bent portion 420. The mounting portion 320 is vertically arranged at the top of the flat plate 310 and remains perpendicular to the top of the complete portion.

[0064] At the same time, the top ends of the mounting plate 300 and the transition plate 400 are higher than the top end of the base plate 100 , thus providing a wider adjustment range for the tensioning wheel 30 .

[0065] In this embodiment, a through-going mating through hole 321 is provided on the mounting portion 320, and an internal thread is provided on the inner wall of the mating through hole 321. The adjusting member 32 is a rod member (or a bolt) with an external thread, one end of the adjusting member 32 is threadedly mated with the mating through hole 321, and the other end of the adjusting member 32 passes through the mating through hole 321 and is fixedly connected with the rotating shaft 31 of the tensioning wheel 30. By rotating the adjusting member 32, the tensioning wheel 30 can be moved along the extending direction of the adjusting slot 301, thereby adjusting the tension of the belt.

[0066] Specifically, from Figure 5 It can be seen that the pulley 21 of the compressor 20 and the tensioning wheel 30 are located on the same side of the bottom plate 100, and the tensioning wheel 30 and the pulley 21 are located in the same plane. The connecting belt 40 passes through the compressor 20 pulley 21 in sequence, and the tensioning wheel 30 is connected to the matching wheel on the engine, so as to form a belt transmission connection. When the engine rotates, the matching wheel drives the compressor 20 pulley 21 to rotate through the connecting belt 40, thereby driving the compressor 20 to work. By adjusting the tensioning wheel 30 to move along the direction of the adjusting slot 301, the tension or relaxation of the connecting belt 40 can be adjusted.

[0067] from Figure 3 It can also be seen that the compressor bracket 10 also includes a partition 510 and a connecting column 520. The partition 510 is vertically arranged on the back of the bottom plate 100 away from the pillar 200, and the partition 510 extends from the top of the bottom plate 100 to the bottom. Further, the partition 510 is located in the middle of the width direction of the bottom, and the notch 101 that cooperates with the mounting plate 300 is located on one side of the partition 510. The partition 510 is provided with a plurality of matching holes 530, and the connecting column 520 is vertically arranged on the back of the bottom plate 100, located on the same surface as the partition 510, and the connecting column 520 is located on the side of the partition 510 away from the mounting plate 300. The connecting column 520 is also provided with a matching hole 530 extending along its height direction.

[0068] The compressor bracket 10 in this embodiment further includes a partition 510 and two connecting columns 520, the two connecting columns 520 are arranged along the height direction of the bottom plate 100 and are kept parallel to the partition 510. The partition 510 is provided with two matching holes 530 extending along the height direction, and the two matching holes 530 vertically penetrate the surface of the partition 510. The matching holes 530 here fix the compressor bracket 10 on the engine.

[0069] It can also be seen from the figure that the compressor bracket 10 also includes a support plate 600 arranged at the bottom of the base plate 100, and the support plate 600 includes a first plate 610 and a second plate 620 that are perpendicular to each other. The first plate 610 and the second plate 620 are connected by a smooth bending transition. The first plate 610 is arranged at the bottom of the base plate 100 along the extension direction of the pillar 200, and the first plate 610 is located between the two pillars 200 below the base plate 100. The second plate 620 extends along the height direction of the base plate 100.

[0070] Both ends of the length of the support plate 600, namely the end of the first plate 610 away from the second plate 620, and the end of the second plate 620 away from the first plate 610, are provided with matching nuts 630, which are used to provide fixed support for the clamps fixing the pipelines on the engine.

[0071] When in use, four cylindrical pillars 200 are installed on the base plate 100 (taking welding as an example), and the compressor 20 is fixed on the pillars 200 by four bolts. The pillars 200 play a dual role of supporting and fixing the compressor bracket 10; a tensioning wheel 30 is placed on a mounting plate 300 welded with an oblong adjustment slot 301 on the back of the base plate 100, and the tensioning wheel 30 can slide along the adjustment slot 301 on the mounting plate 300 through an adjusting piece 32 (taking bolts as an example), thereby achieving the purpose of tensioning the belt.

[0072] In a second aspect, an embodiment provides an air conditioning system, the air conditioning system comprising a compressor 20 and a compressor bracket 10 according to any one of the aforementioned embodiments; the compressor 20 is detachably disposed on the compressor bracket 10 .

[0073] The support 200 disposed on the bottom plate 100 is connected to the compressor 20. The support 200 integrates the functions of supporting and fixing the compressor 20 and has a simple structure. The bent mounting plate 300 with a long groove and the tensioning wheel 30 can well realize the tensioning of the belt.

[0074] In a third aspect, an embodiment provides an excavator, the excavator comprising the air conditioning system of the aforementioned embodiment. Such an excavator has good economic benefits.

[0075] The compressor bracket 10 provided in this embodiment has at least the following advantages:

[0076] The compressor bracket 10 includes a base plate 100 and a plurality of pillars 200; the compressor 20 is detachably arranged on the base plate 100 through the pillars 200, thereby avoiding the problems of inconvenience in processing and installation on the base plate 100 and low installation efficiency. Such a compressor bracket 10 can improve the installation efficiency of the compressor 20 and has significant economic benefits. Specifically:

[0077] a) The structure is simple, the length of the fixing bolts of the compressor 20 is reduced, and the installation is convenient.

[0078] b) It avoids the deformation of the threaded hole of the base plate 100 caused by welding the cylindrical sleeve in the existing design and the problem of re-tapping, thereby reducing the number of working steps.

[0079] c) A mounting plate 300 with a long slot can conveniently solve the belt tensioning problem.

[0080] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto.
