[0002] Currently, when transporting heat pump units, the various components of the unit often need to be screwed to wooden supports, and additional shock-absorbing features are used to prevent damage to the components due to the bumps of the transport vehicle during transportation. Furthermore, when installing the heat pump unit, users need to pre-install brackets on the ground, remove the unit from the wooden supports, attach shock-absorbing feet to the unit, and then mount the unit on the brackets. Finally, a professional level is used to level the components. The entire transportation and installation process is extremely inconvenient and cumbersome. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings and deficiencies in the prior art and to provide a chassis to solve the problems of inconvenient transportation and complicated installation of a heat pump unit.

[0004] The utility model is realized through the following technical solution: a chassis includes a first supporting structure, the first supporting structure includes a first supporting plate for supporting objects and a plurality of first supporting columns, the plurality of first supporting columns are fixed on one side of the first supporting plate to support the first supporting plate, a plurality of first folding plates are provided at the edge of the first supporting plate, and the first supporting plate and the first supporting columns are fixedly connected through the first folding plates.

[0005] Compared with the prior art, the chassis described in the present invention can prevent the tearing problem caused by the integrated connection between the first supporting plate and the first supporting column during transportation through the first supporting structure, thereby improving the stability of the object during transportation, facilitating the installation of the chassis, and improving installation efficiency.

[0006] Furthermore, the side of the first supporting column is provided with a plurality of protruding supporting members, which abut against the first folding plate to support the first supporting plate. By supporting the first folding plate with a plurality of supporting members, the first supporting plate can be stably supported.

[0007] Furthermore, the first support plate is provided with a plurality of second folding plates at its edge, the second folding plates being bent in a direction opposite to that of the first folding plates, and the second folding plates being fixedly connected to the first support column. This snap-fit ​​connection further strengthens the connection between the first support plate and the first support column, and is very convenient for installation.

[0008] Furthermore, the first supporting column includes a supporting foot and a connecting plate, and two adjacent supporting feet are fixedly connected via the connecting plate, which can make the connection between the two adjacent first supporting columns more stable, thereby improving the overall supporting force of the two adjacent first supporting columns.

[0009] Furthermore, the first supporting plate is provided with a plurality of third folding plates at the edge of the first folding edge, wherein the bending direction of the third folding plates is opposite to that of the first folding plates, and the third folding plates are fixedly connected to the side surfaces of the supporting legs. This can make the connection between the first supporting column and the first supporting plate more stable.

[0010] Furthermore, a portion of two adjacent supporting legs located above the connecting plate near the middle of the first supporting plate is arranged at an obtuse angle to the connecting plate, which can increase the force bearing area at the contact point between the first supporting column and the first supporting plate, thereby better supporting the first supporting plate.

[0011] Furthermore, a second supporting structure is provided at an end of the first supporting column away from the first supporting plate. The second supporting structure can enhance the supporting force of the first supporting structure and can also provide a buffering effect, eliminating the need for additional shock-absorbing devices during transportation, thereby facilitating transportation.

[0012] Furthermore, a third supporting structure is provided below the first supporting plate to support the first supporting plate. This structure provides support for the first supporting plate to prevent deformation of the first supporting plate caused by the greater gravity of the heat pump unit and the impact of bumps. Furthermore, the third supporting structure, when placed at the bottom of the first supporting plate, protects the first and second supporting structures from being scratched by forklifts during transportation.

[0013] Furthermore, the third supporting structure is fixed in the space formed by the first supporting structure and the second supporting structure. Fixing the third supporting structure can prevent displacement due to vehicle bumps during transportation.

[0014] Furthermore, the third supporting structure includes a third supporting plate, a third supporting column and a limiting block, wherein the third supporting column is fixed to one side of the third supporting plate, the limiting block is fixed to the side of the third supporting plate away from the third supporting column, the end of the third supporting plate is against the first supporting column, a plurality of reinforcing plates are spaced apart at the lower end of the first supporting plate, and the limiting block is fixed in the gap between the reinforcing plates. Through the screwless fixing method of the third supporting structure and the first supporting structure and the second supporting structure, after the heat pump unit and its chassis structure are installed on the base, the third supporting structure is suspended below and will naturally fall off and can be directly taken out, thereby improving the installation efficiency of the heat pump unit; the reinforcing plate can enhance the rigidity of the first supporting plate to better support the heat pump unit installed on the first supporting plate.

[0015] The utility model also provides a heat pump unit, comprising any one of the above-mentioned chassis.

DETAILED DESCRIPTION

[0023] During the transportation of the heat pump unit body, in order to prevent the heat pump unit body from being damaged, a protective device needs to be installed at the bottom of the heat pump unit body. When the heat pump unit body is transported to the installation point, the engineering personnel need to first install the chassis structure on the base, and then remove the heat pump unit body from the protective device and fix it on the chassis structure. The whole process is quite cumbersome. The inventor thought of fixing the chassis structure installed on the base to the bottom of the heat pump unit body before leaving the factory. There is no need to set up an additional protective device during transportation. When arriving at the installation point, the heat pump unit body and the chassis structure at the bottom can be directly transported to the base for fixed installation. At the same time, the inventor designed the chassis structure to prevent the chassis structure from being unstable or even breaking or deforming due to bumps during transportation, thereby ensuring that the heat pump unit body is not damaged and making the installation of the entire heat pump unit more convenient and simple. Based on this, the present invention proposes a chassis. The specific implementation method of this application will be described in detail through specific examples below:

[0024] Please also see Figures 1 to 4 The chassis described in this application includes a first supporting structure 10, a second supporting structure 20 and a third supporting structure 30.

[0025] Specifically, the first supporting structure 10 includes a first supporting plate 11 and a first supporting column 12 for supporting an object. During use, the object to be supported is fixedly mounted on one side of the first supporting plate 11, and the first supporting column 12 is fixed to the side of the first supporting plate 11 away from the object, thereby supporting the first supporting plate 11 and the object mounted on the first supporting plate 11. In this embodiment, the object is a heat pump unit body, and the first supporting plate 11 is provided with a plurality of mounting holes for mounting the heat pump unit body and drainage holes for drainage.

[0026] The edge of the first supporting plate 11 is provided with a plurality of first folding plates 111, and the bending direction of the first folding plates 111 is toward the first supporting column 12. The edge of the first supporting plate 11 is also provided with a plurality of second folding plates 112, and the bending direction of the second folding plates 112 is opposite to the bending direction of the first folding plates 111.

[0027] In this embodiment, the first folding plates 111 are two pieces, each of which is vertically connected to a set of parallel and opposite sides of the first supporting plate 11. The first folding plates 111 are bent toward the first supporting column 12. The second folding plates 112 are two pieces, each of which is vertically connected to another set of parallel and opposite sides of the first supporting plate 11. The second folding plates 112 are bent in the opposite direction to the first folding plates 111. The second folding plates 112 can protect and limit the bottom of the heat pump unit body.

[0028] The first support plate 11 is provided with a third folded plate 113 on each edge of the first folded plate 111. The straight portion of the third folded plate 113 bends in the opposite direction of the first folded plate 111. The third folded plate 113 can be integrally connected to the first support plate 11 vertically or separately. In this embodiment, the separate connection is used to prevent tearing due to bumps during transportation when the integral connection is used and to provide a more flexible fixed connection to the first support column 12. The third folded plate 113 also serves as a position limiter for the heat pump unit body mounted on the first support plate 11. Specifically, one end of the third folded plate 113 is provided with multiple protrusions, and the first support plate 11 is provided with locking holes that match the multiple protrusions. The protrusions snap into the corresponding locking holes. Preferably, the first support plate 11 is a rectangular plate, with two first folded plates 111 provided on either side of the width, and two second folded plates 112 provided on either side of the length.

[0029] There are multiple first support columns 12, each of which is evenly fixed to the side of the first support plate 11 facing away from the heat pump unit body to support the first support plate 11 and the heat pump unit body mounted on the first support plate 11. Preferably, there are two first support columns 12, each fixed to either end of the side of the first support plate 11 facing away from the heat pump unit body. Each first support column 12 includes a support leg 121 and a connecting plate 122. Two adjacent support legs 121 at the same end of the first support plate 11 are positioned opposite each other, and the two adjacent support legs 121 are fixedly connected by the connecting plate 122 to form a hollow support structure. Two adjacent support legs 121 and the connecting plate 122 may be integrally welded. Preferably, the connecting plate 122 is parallel to the first support plate 11. More preferably, the connecting plate 122 is positioned on the end of the support leg 121 facing away from the first support plate 11. The connection between the connecting plate 122 and the supporting leg 121 is chamfered for a more aesthetically pleasing appearance. A portion of the connecting plate 122, located between two adjacent supporting legs 121 and located above the connecting plate 122, near the center of the first supporting plate 11, forms an angle α with the connecting plate 122, preferably an obtuse angle, to increase the force-bearing area at the contact point between the supporting leg 121 and the first supporting plate 11, thereby better supporting the first supporting plate 11.

[0030] A plurality of protruding supporting members 123 are provided on the first supporting column 12. The supporting members 123 are arranged on the side of the first supporting column 12 facing the middle of the first supporting plate 11 and match the first folding plate 111. The plurality of supporting members 123 provided on each first supporting column 12 can be a plate having a certain thickness as a whole, or can be composed of a plurality of plates having a certain thickness arranged in an array. In this embodiment, the supporting member 123 on each first supporting column 12 is a plate having a certain thickness as a whole, which is fixed to the inner side surface of the supporting leg 121 located on the outside by screws. The lower end of the first folding plate 111 abuts against the upper end of the supporting member 123 so that the first supporting plate 11 is supported, fixed and positioned by the supporting member 123 through the first folding plate 111. At the same time, the second folding plate 112 is fixed to the first supporting column 12, which can further strengthen the fixation between the first supporting plate 11 and the first supporting column 12. In this embodiment, the second folding plate 112 has buckle protrusions 112a at both ends, and the first supporting column 12 has buckle grooves 12a matching the buckle protrusions 112a. The buckle protrusions 112a on the second folding plate 112 are buckled into the corresponding buckle grooves 12a.

[0031] The third folding plate 113 is fixedly connected to the side of the first supporting column 12 facing the middle of the first supporting plate 11, so that the connection between the first supporting column 12 and the first supporting plate 11 is more stable. In this embodiment, the upper end of the supporting leg 121 located on the outside is flush with the upper end of the third folding plate 113 to ensure the flatness of the first supporting column 12 when connected to the first supporting plate 11, while limiting the position and bottom protection of the heat pump unit body installed on the first supporting plate 11. Preferably, the third folding plate 113 is fixedly connected to the side of the first supporting column 12 facing the middle of the first supporting plate 11 by screws.

[0032] More preferably, after the first supporting column 12 is connected to the first supporting plate 11, a buffer is further provided in the space formed by the fixed connection between the two adjacent supporting legs 121 and the connecting plate 122. The buffer can further enhance the supporting effect of the first supporting column 12 and has a good buffering effect, which facilitates the transportation and installation of the first supporting structure 10 and the main body of the heat pump unit thereon without the need for additional buffer components.

[0033] See also Figure 5 In order to enhance the rigidity of the first supporting plate 11 so as to better support the heat pump unit body mounted on the first supporting plate 11, a plurality of reinforcing plates 13 are provided on the side of the first supporting plate 11 away from the heat pump unit body. The plurality of reinforcing plates 13 are arranged in parallel at intervals and the two ends of each reinforcing plate 13 are respectively fixed to the first supporting columns 12 at both ends.

[0034] The use of this snap-fit ​​and supporting connection and fixation method between the split first supporting plate 11 and the first supporting column 12 can prevent the first supporting plate 11 and the first supporting column 12 from tearing due to integral welding during transportation, and will not affect the flatness of the appearance.

[0035] The second supporting structure 20 includes a second supporting column 21, which is arranged at an end of the first supporting column 12 away from the first supporting plate 11 to further support the first supporting structure 10 and the heat pump unit body arranged on the first supporting structure 10. The second supporting column 21 can be made of a rigid material, or made of a shock-absorbing material, preferably made of a shock-absorbing material so that the second supporting structure 20 has both supporting and shock-absorbing effects. The installation and fixation of the second supporting column 21 and the first supporting column 12 can be completed directly in the factory, so that there is no need to add additional shock-absorbing settings during transportation, and when the user installs the heat pump unit body, there is no need to install additional shock-absorbing feet, and the heat pump unit body and its chassis can be directly fixed on the base.

[0036] In addition, each second supporting column 21 is provided with a plurality of spirit levels 22, preferably four, which are respectively arranged on the four sides. The spirit levels 22 on the second supporting column 21 can assist the user in performing horizontal adjustments after installing the heat pump unit body, without the need to prepare additional horizontal debugging instruments for horizontal debugging, which simplifies the installation process of the heat pump unit body and greatly improves the installation and debugging efficiency of the heat pump unit body. The cross-section of the second supporting column 21 can be set to different shapes, preferably trapezoidal, so that the force-bearing area at the bottom of the second supporting column 21 is larger, making the entire chassis installation more stable, and at the same time, it is convenient to drill holes on the trapezoidal inclined surface and then fix the second supporting column 21 to the base with bolts. At the same time, the bottom of the second supporting column 21 is provided with multiple openings for installation and fixing on the mounting column of the base.

[0037] The third support structure 30 is disposed on the side of the first support plate 11 away from the heat pump unit body. The overall height of the third support structure 30 is equal to the distance between the side of the first support plate 11 away from the heat pump unit body and the ground, so that the third support structure 30 supports the first support plate 11. The third support structure 30 is fixed in the space formed by the first support column 12, the first support plate 11, and the reinforcing plate 13. During transportation, the third support structure 30 prevents the first support plate 11 from being deformed by the greater weight of the heat pump unit body and the impact force caused by bumps.

[0038] Specifically, the third supporting structure 30 includes a third supporting plate 31, a third supporting column 32, and a limiting block 33. The third supporting columns 32 are multiple and fixed to one side of the third supporting plate 31. The limiting block 33 is fixed to the side of the third supporting plate 31 away from the third supporting column 32. The end of the third supporting plate 31 abuts against the first supporting column 12, and the limiting block 33 is fixed in the gap between the reinforcing plates 13. Preferably, there are three third supporting columns 32, two of which are vertically fixed to the two ends of the side of the third supporting plate 31 away from the first supporting plate 11 and abut against the first supporting column 12 to limit the third supporting structure 30 along the two second folding plates 112. The other is arranged in the middle of the third supporting plate 31 to strengthen the supporting force of the third supporting structure 30 and make the force on the three third supporting columns 32 more balanced. In addition, the height of the third support column 32 needs to ensure that after the entire third support structure 30 is fixed to the side of the first support plate 11 away from the installation of the heat pump unit body, the end of the third support column 32 away from the third support plate 31 is flush with the end of the second support column 21 away from the first support column 12, so that the third support structure 30 can support the first support plate 11 and the heat pump unit body installed on the first support plate 11, thereby preventing the first support plate 11 from being deformed due to bumps during transportation. There are multiple limit blocks 33 and they are arranged on the side of the third support plate 31 away from the third support column 32. The positions of the multiple limit blocks 33 match the gap positions between the multiple reinforcing plates 13. The limit blocks 33 are fixed in the gaps between the reinforcing plates 13 to limit the third support structure 30 along the direction of the first folding plate 111. During the transportation of the chassis and the heat pump unit body above it, the third supporting structure 30 has the same overall height as the height of the side of the first supporting plate 11 away from the heat pump unit body from the ground, and is limited in both directions of the first folding plate 111 and the second folding plate 112 of the first supporting plate 11, and is fixed under the first supporting plate 11 and will not move.

[0039] Because the third supporting structure 30 is secured between the first supporting structure 10 and the second supporting structure 20 by means of a position-limiting mechanism, after the heat pump unit body and its chassis are mounted on the base, the third supporting structure 30 is suspended below and will naturally fall out, allowing for direct removal, thereby improving the installation efficiency of the entire heat pump unit. Furthermore, when the third supporting structure 30 is placed on the side of the first supporting plate 11 away from the heat pump unit body, it protects the first supporting structure 10 and the second supporting structure 20 from being scratched by a forklift.

[0040] Furthermore, the first supporting plate 11, first folding plate 111, second folding plate 112, third folding plate 113, supporting legs 121, connecting plate 122, and reinforcing plate 13 are all made of steel plates, which have strong rigidity and thus a strong load-bearing capacity. The third supporting structure 30 can be made of steel plates or wooden plates, preferably wooden plates. Wooden plates offer a strong load-bearing capacity while also being lightweight and cost-effective. Furthermore, because wooden plates are less hard than steel plates, the wooden third supporting structure 30 is more easily secured between the various chassis components and is less likely to damage them.

[0041] Furthermore, any of the above-mentioned chassis can be used for the transportation and installation of any object, such as a refrigeration unit, a generator set, etc.

[0042] The utility model also provides a heat pump unit, comprising any one of the above-mentioned chassis, wherein the chassis is arranged at the bottom of the heat pump unit body.

[0043] Compared with the prior art, the chassis described in the present application connects the split first supporting plate 11 and the first supporting column 12 by means of snap-fit ​​fixing and supporting fixing, which ensures a smooth appearance while preventing the first supporting plate 11 and the first supporting column 12 from being torn due to integral welding during transportation, thereby improving the stability of the heat pump unit during transportation, facilitating the installation of the heat pump unit, and improving the installation efficiency; at the same time, by providing a second supporting structure 20, while supporting the first supporting structure 10 and the heat pump unit, it can also play a shock-absorbing role, further improving the stability and convenience of the heat pump unit during transportation; in addition, by providing a third supporting structure 30 that is not fixed to the first supporting structure 10 and the second supporting structure 20 with screws, it is only necessary to place the second supporting structure 20 under the first supporting column 12 during installation. After installation, the third supporting structure 30 can be dropped directly from below, facilitating the installation of the heat pump unit; in addition, by providing a level 22 on the second supporting column 21, the user's installation and debugging efficiency of the heat pump unit is greatly improved.

[0044] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
