[0036] A rotary work machine such as a shovel generally includes a traveling device such as a track or a wheel, a rotary platform connected to the traveling device, and a working device such as a boom, a stick, and a bucket connected to the rotary platform. Various cabins or equipment (for example, a cab, an engine, a fuel tank, a hydraulic oil tank, a pump room, etc.) equipped for the traveling and / or working of the work machine are installed on the rotary platform, thereby constituting a rotary platform assembly. The rotary platform assembly is further installed on the traveling device and can be rotated with respect thereto.

[0037] Figure 1 and 2 A rotary platform assembly of a work machine according to one embodiment of the present application is schematically shown, which can include a rotary platform and a plurality of integrated modules 1. The rotary platform can include a center frame 2 extending in the advancing direction of the work machine. Exemplarily, in this embodiment, the rotary platform can further include a side skirt frame, i.e., a left skirt frame, connected to the first side of the center frame 2. The side skirt frame can be integrally connected with the center frame 2 for mounting, for example, a cab, etc. The plurality of integrated modules 1 can be various cabins or equipment including, but not limited to, a pump room, a hydraulic oil tank, a fuel tank, a storage tank, a cooling equipment, etc. The plurality of integrated modules 1 are installed to the center frame 2 at the second side of the center frame 2 opposite to the first side, and the plurality of integrated modules 1 are sequentially and adjacently installed in the advancing direction (X direction), and two adjacent integrated modules 1 are connected with each other, for example, at the outer side away from the center frame 2 of the bottom thereof (for example, by the first fixing bracket 5 and the second fixing bracket 6 to be described below).

[0038] The plurality of integrated modules 1 mainly include some devices or parts of the working machine, such as a storage tank, a fuel tank, a hydraulic oil tank, a pump chamber, etc. As described above, in the prior art, these devices or parts are sequentially and directly installed on the left or right skirt frame of the slewing platform assembly, and the slewing platform assembly has the disadvantages of large size, complex structure, large weight, high cost, complex assembly, high consumption of manpower and time, etc. In the present application, the plurality of integrated modules 1 can pre-assemble at least one device or part to form an integrated module 1, and then directly install it to the right side of the center frame 2. By sequentially installing each integrated module 1 to the center frame 2 and connecting adjacent two integrated modules, the connection stiffness and strength of each integrated module 1 can meet the use requirements, thereby omitting the right skirt frame in the prior art, increasing material utilization, reducing cost, reducing the number of parts and management cost, and improving assembly speed.

[0039] In the above embodiment, as shown in Figure 3 The center frame 2 can include a bottom plate 21 and two vertical plates 22 perpendicular to the bottom plate 21, and the two vertical plates 22 are respectively arranged on the left and right sides of the center frame 2. At least one of the vertical plate 22 and the bottom plate 21 on the second side of the center frame 2 is provided with a mounting structure 23 for connecting a plurality of integrated modules 1. That is, the mounting structure 23 can be welded to the vertical plate 22, or welded to the bottom plate 21, or welded to both the vertical plate 22 and the bottom plate 21 to improve the connection strength with the center frame 2. Figure 3 It is also shown that three integrated modules 1, and the front two integrated modules 1 can be detachably connected by the first fixed support 5, and the rear two integrated modules 2 can be detachably connected by the second fixed support 6. In this way, one of the integrated modules can be individually disassembled for later repair or maintenance.

[0040] Referring to Figure 2 According to the present embodiment, the plurality of integrated modules 1 can be a first module 11, a second module 12 and a third module 13 arranged from front to back in the longitudinal direction X. The slewing platform assembly of the present embodiment can also include a side beam assembly 4 arranged at the bottom of the side away from the center frame 2 of the first module 11, the second module 12 and the third module 13. The side beam assembly 4 can include a front side beam 41 and a rear side beam 42 arranged in sequence from front to back. The front side beam 41 is connected to the first module 11, and the rear side beam 42 is connected to the second module 12 and the third module 13, thereby reducing the maintenance cost of the side beam assembly 4. For example, when the front part of the side beam assembly 4 is damaged by impact, only the front side beam 41 needs to be replaced.

[0041] Preferably, the first module 11 can include a storage tank 111 and a fuel tank 112 integrated as one. The second module 12 can include a hydraulic oil tank 121. The third module 13 can include a pump chamber 131. The storage tank 111, the fuel tank 112, the hydraulic oil tank 121 and the pump chamber 131 are arranged in sequence from front to back along the X direction, as shown in Figure 3 and Figure 4 . Among them, the bottom of the storage tank 111 is lower than the bottom of the fuel tank 112, and a first side beam support 43 is arranged at the bottom of the fuel tank 112. In this way, the front part of the front side beam 41 is directly connected to the lower part of the storage tank 111, and the rear part of the front side beam 42 is connected to the first side beam support 43 and to the bottom of the fuel tank 112 via the first side beam support 43. In this way, the front side beam 41 can cover the lower part of the storage tank 111 and the position from the bottom of the fuel tank 112 to the bottom of the first side beam support 43. Similarly, the bottom of the pump chamber 131 of the third module 13 is lower than the bottom of the hydraulic oil tank 121 of the second module 12. A second side beam support 44 is arranged at the bottom of the second module 12. In this way, the front part of the rear side beam 42 is connected to the second side beam support 44 and to the bottom of the hydraulic oil tank 121 via the second side beam support 44. The rear part of the rear side beam 42 is directly connected to the bottom of the pump chamber 131. In this way, the rear side beam 42 can cover the lower part of the pump chamber 131 and the position from the bottom of the hydraulic oil tank 121 to the bottom of the second side beam support 44. Moreover, the front side beam 41 and the rear side beam 42 can be arranged at the same height, which is conducive to optimizing the force transmission path when encountering a collision.

[0042] Figure 5 and Figure 6 The specific structure of the connection of the first module 11 to the center frame 2 according to the present embodiment is shown. As shown in Figure 5 and Figure 6 , the first module 11 is provided with a first connecting portion 114 at the front end of the storage tank 111. The bottom wall of the storage tank 111 overlaps with the bottom plate 21 of the center frame 2, and a partial portion of the storage tank 111 corresponding to this overlapping portion can be used as the first connecting portion 114. The first module 11 can be connected to the center frame 2 at the position of the first connecting portion 114. For example, the first connecting portion 114 is provided with a plurality of holes, and the first module 11 is connected to the center frame 2 at this position via fasteners passing through the bottom wall of the storage tank 111 and the bottom plate 21 of the center frame 2. Mainly, the first module 11 is provided with a first bracket 113 at the bottom of the fuel tank 112 and is connected to the mounting structure 23 of the center frame 2 via the first bracket 113. In this way, the first module 11 is connected to the center frame 2 only at the positions of the first connecting portion 114 and the first bracket 113, which can simplify the assembly process during installation and the disassembly process during later maintenance of the first module 11.

[0043] Specifically, the first bracket 113 may include two L-shaped supports 115 and a mounting plate 116 connecting the two L-shaped supports 115 to each other. The mounting plate 116 can be attached to the upright plate 22 of the central frame 2 and fixed to the upright plate 22 in a first direction (Y direction) via a plurality of first fasteners 31. The mounting structure 23 may include a plurality of support members 231 that engage with each L-shaped support 115. For example, a groove is provided on the upper end of the support member 231 on the side of the upright plate 22 near the central frame 2, into which the vertical branch of the corresponding L-shaped support 115 can be engaged. The top of the support member 231 can abut against the horizontal branch of the L-shaped support 115. A second fastener 32 can pass through the support member 231 in a second direction (Z direction) and enter into the horizontal branch of the L-shaped support 115, thus fixing the L-shaped support 115 to the support member 231 in the second direction. Thus, the first bracket 113 is configured to be fixed to the central frame 2 in both the first and second directions. Understandably, the number of L-shaped brackets 115 in each first bracket 113 can be one or more, depending on the extension length of the first module 11, especially the fuel tank 112, in the X direction. Furthermore, the first fixing bracket 5 can be welded to the rear side of the fuel tank 112 in the X direction and extend towards the second module 12, thereby facilitating connection with the second module 12 in a third direction, i.e., the X direction (i.e., fasteners pass through the first fixing bracket 5 along the X direction). Thus, the first module 1 can be connected and fixed in the first, second, and third directions, avoiding failure caused by loosening of fasteners such as bolts in one direction, and improving the reliability of the first module 1's fixation.

[0044] Figure 7 The specific connection structure of the second module 12 to the central frame 2 according to this embodiment is shown. For example... Figure 7 As shown, the second module 12 has a second bracket 122 at the bottom of the hydraulic oil tank 121, and is connected to the mounting structure 23 of the center frame 2 via the second bracket 122. In this way, the second module 12 is connected to the center frame 2 only at the position of the second bracket 122, which simplifies the assembly process during the installation of the second module 12 and the disassembly process during subsequent maintenance.

[0045] Specifically, the second bracket 122 can include two L-shaped supports 123 and a mounting plate 124 connecting the two L-shaped supports 123 to each other. The mounting structure 23 can include two supporting members 232 fitting with each L-shaped support 123. When each L-shaped support 123 is fitted into the corresponding supporting member 232, the mounting plate 124 can be attached to the upright plate 22 of the center frame 2 and fixed in the first direction (Y direction) via a plurality of third fasteners 33. The top of the supporting member 232 can be engaged with the horizontal branch of the L-shaped support 123 and fixed by the fourth fastener 34 in the second direction (Z direction). The hydraulic oil tank 121 of the second module 12 is detachably connected to the first fixed support 5 via fasteners in the third direction (X direction), thereby fixing the second module 12 with the first module 11. One of the L-shaped supports 123 of the second module 12 shown in the figure is arranged at the edge of the hydraulic oil tank 121 close to the first module 11 (e.g. connected to the bottom of the hydraulic oil tank 121 in the form of welding), so that it can be directly detachably fixed by the fastener directly penetrating through the L-shaped support and the first fixed support 5. Of course, the first fixed support 5 can also be arranged on the front side of the bottom of the hydraulic oil tank 121 in the form of welding, and the first module 11 is detachably connected to the first fixed support 5. In addition, the second fixed support 6 is connected to the rear side of the hydraulic oil tank 121 in the X direction and extends towards the third module 13 in the form of welding.

[0046] Figure 8 The specific connection structure of the third module 13 connected to the center frame 2 according to the present embodiment is shown. As shown in the figure, the pump chamber 131 of the third module 13 can include a frame, and a second connection part 132 is integrated on the side of the frame close to the center frame 2. The mounting structure 23 can include a mounting member 233 engaged with the second connection part 132. The mounting member 233 extends right from the upright plate 22 of the center frame 2 and has an overlapping part with the second connection part 132, so that the mounting member 233 and the second connection part can be fixed via the fifth fastener 35. In addition, the front side of the frame in the X direction is also detachably connected to the second fixed support 6 via fasteners in the X direction. In other embodiments, the second fixed support 6 can also be connected to the frame of the third module 13 in the form of welding, and the hydraulic oil tank 121 of the second module 12 and / or the second bracket 122 can be detachably connected to the second fixed support 6 via fasteners. Figure 8 The utility model discloses still provide a kind of working machine comprising above-mentioned rotary platform assembly.

[0050] When assembling the rotary platform assembly as shown in Figure 1 , the first module 11, the second module 12 and the third module 13 as shown in Figure 2 can be pre-assembled. Then the three modules 11, 12 and 13 are installed on the rotary platform. Finally, the front edge beam 41 of the edge beam assembly 4 is installed on the first module 11, and the rear edge beam 42 is installed on the second module 12 and the third module 13.

[0051] When assembling the first module 11, the second module 12 and the third module 13, the integrated module of the storage tank 111 and the fuel tank 112 can be provided first, and two L-shaped supports 115 are welded at the bottom of the module and the mounting plate 116 is welded between the two L-shaped supports 115. The first fixed support 5 and the first edge beam support 43 are respectively welded to the corresponding positions at the bottom of the module, thereby forming the first module 11 integrated with the first fixed support 5 and the first bracket 112. In a similar manner, the second bracket 122, the second fixed support 6 and the second edge beam support 44 are integrated into the bottom of the hydraulic oil tank 121 to form the second module 12.

[0052] Meanwhile, the supporting members 231, 232 and the mounting member 233 of the mounting structure 23 are welded to the bottom plate 21 and / or the vertical plate 22 of the center frame 2, for example. Then the modules are specifically mounted on the center frame 2.

[0053] The vertical branch of the L-shaped support 115 of the first module 11 is embedded in the corresponding supporting member 231. The first module 11 and the center frame 2 are directly fixed in the first direction (Y direction) by the first fastener 31 passing through the mounting plate 116 and the vertical plate 22 of the center frame 2. The first module 11 is fixed with the center frame 2 in the second direction (Z direction) via the supporting member 231 by the second fastener 32 fixed to the horizontal branch of the L-shaped support 115. At this time, the connecting hole of the first connecting part 114 is aligned with the hole position on the bottom plate 21, and the corresponding fastener passes through the first connecting part 114 and the bottom plate 21 to detachably fix the front end of the first module 11 with the center frame 2.

[0054] The vertical branch of the L-shaped bracket 123 of the second module 12 is embedded with the corresponding supporting member 232. The second module 12 and the center frame 2 are directly fixed in the first direction (Y direction) by the third fastener 33 passing through the mounting plate 124 and the vertical plate 22 of the center frame 2. The second module 12 is fixed to the center frame 2 in the second direction (Z direction) via the supporting member 232 by the fourth fastener 34 passing through the horizontal branch of the L-shaped bracket 123 and the supporting member 232. The front end of the second module 12 can be fixed to the first module 11 by the fastener passing through the L-shaped bracket 123 of the front side of the second bracket 122 and the first fixed bracket 5 in the third direction (X direction).

[0055] The second connecting part 132 of the third module 13 is fixed to the center frame 2 after being aligned with the mounting member 233 via the fifth fastener 35. The front end of the third module 13 can be fixed to the second module 12 by the fastener passing through the connecting part arranged at the front end of the frame of the third module 13 and the second fixed bracket 6. In this way, the first module 11, the second module 12 and the third module 13 are sequentially installed to the right side of the center frame 2 of the slewing platform, and then the installation of the side beam assembly 4 is performed.

[0056] The front part and the rear part of the front side beam 41 can be detachably connected to the bottom of the storage box 111 and the first side beam bracket 43 via the fastener. The front part and the rear part of the rear side beam 42 are detachably fixed to the second side beam bracket 44 and the bottom of the frame of the third module 13, respectively, via the fastener. Therefore, the front side beam 41 and the rear side beam 42 can be conveniently assembled.
