[0043] According to a first aspect of the present invention, a rotatable auxiliary water tank mounting structure is provided, which includes a first support member 11, a second support member 12, a rotating component 20, and a fastener 30.

[0044] The specific structure of the above-mentioned components of the rotatable auxiliary water tank mounting structure according to this embodiment will be described below.

[0045] In this embodiment, as Figures 1 to 4 As shown, both the first support member 11 and the second support member 12 are plate-shaped structures, such as sheet metal parts. The first support member 11 is mounted on the structural bracket 70. The structural bracket 70 can be a frame structure used to support or carry the engine. The first support member 11 can be mounted on the structural bracket 70 by screws or bolts, so that the mounting position of the first support member 11 is fixed.

[0046] Furthermore, such as Figures 2 to 4 As shown, the auxiliary water tank 50 is installed on the second support member 12; the rotating assembly 20 is disposed between the first support member 11 and the second support member 12, so that the first support member 11 and the second support member 12 are rotatably connected. In this way, when the engine needs maintenance or repair, the second support member 12 can be driven to rotate relative to the first support member 11, thereby driving the auxiliary water tank 50 to rotate and realize the position of the auxiliary water tank 50. This allows for more space for engine maintenance or repair without disassembling the auxiliary water tank 50, saving time and effort and making operation easier.

[0047] Furthermore, one of the first support member 11 and the second support member 12 is provided with a connecting part 101; the other of the first support member 11 and the second support member 12 is provided with a connecting hole 102. The fastener 30 passes through the connecting hole 102 and is detachably connected to the connecting part 101. After maintenance or repair work is completed, the auxiliary water tank 50 is rotated to its original position and locked by the fastener 30, thereby fixing the installation position of the auxiliary water tank 50 and meeting the usage requirements.

[0048] In this embodiment, as Figure 2 and Figure 3 As shown, fastener 30 is preferably a wing nut for easy tightening by the operator. For example... Figure 3 As shown, the connecting hole 102 is provided on the second support member 12, and the connecting hole 102 is a through hole. Figure 3 and Figure 4 As shown, the connecting part 101 is disposed on the first support member 11. The connecting part 101 can be a block support with a threaded hole or a threaded hole directly formed on the first support member 11.

[0049] It should be noted that, in other alternative embodiments, the connecting hole 102 may also be provided on the first support member 11, and the connecting part 101 may be provided on the second support member 12.

[0050] like Figure 1As shown, the engine assembly is housed within the structural support 70. The engine assembly includes an engine generator 81 and an engine oil filter 82. The auxiliary water tank 50 is located on the side of the engine assembly facing the outside of the structural support 70. Specifically, relative to the entire machine, the auxiliary water tank 50 is located on the rear side of the engine assembly. Therefore, by opening the rear hood of the entire machine housing, it can be observed that the installation position of the auxiliary water tank 50 obstructs at least some components of the engine assembly. In this embodiment, the first support member 11 is fixedly connected to the column 71 on the structural support 70. The column 71 can be a rod-like structure or a column-like structure extending in a vertical direction. The second support member 12 can drive the auxiliary water tank 50 to rotate around the column 71. Thus, when maintenance or repair is required, the fasteners 30 can be loosened, and the second support member 12 can be rotated so that the auxiliary water tank 50 no longer obstructs the view, thereby providing more space for maintenance or repair work.

[0051] like Figure 2 As shown, the auxiliary water tank 50 is equipped with a conveying interface. The radiator overflow hose and / or the auxiliary water tank overflow hose can be installed on the conveying interface through clamps 60, which has the advantages of convenient installation and good sealing.

[0052] In the first implementation, such as Figures 2 to 4 As shown, the rotating assembly 20 includes a rotating shaft 21 and a rotating sleeve 22. The rotating shaft 21 is formed as a shaft structure and is fixedly connected to the first support member 11. The rotating shaft 21 and the first support member 11 can be welded together. The rotating sleeve 22 is formed as a sleeve structure fitted onto the rotating shaft 21 and is fixedly connected to the second support member 12. The second support member 12 can be welded to the outer wall of the rotating sleeve 22. Thus, when the rotating sleeve 22 rotates relative to the rotating shaft 21, the second support member 12 rotates around the rotating shaft 21, thereby driving the auxiliary water tank 50 to rotate around the first support member 11.

[0053] In the second embodiment, the rotating assembly 20 includes a rotating shaft 21 and a rotating sleeve 22. The rotating shaft 21 is formed as a shaft structure and is fixedly connected to the second support member 12. The rotating shaft 21 and the second support member 12 can be welded together. The rotating sleeve 22 is formed as a sleeve structure fitted onto the rotating shaft 21 and is fixedly connected to the first support member 11. The first support member 11 can be welded to the outer wall of the rotating sleeve 22. Thus, when the rotating sleeve 22 rotates relative to the rotating shaft 21, the second support member 12 rotates relative to the rotating sleeve 22, thereby enabling the second support member 12 to drive the auxiliary water tank 50 to rotate around the first support member 11.

[0054] Preferably, the rotating shaft 21 extends vertically, and the axis of the rotating sleeve 22 is collinear with the axis of the rotating shaft 21, so that the second support member 12 can translate when rotating, so as to smoothly drive the auxiliary water tank 50 to rotate.

[0055] In this embodiment, as Figure 3 and Figure 4 As shown, a protruding limiting part 211 is formed on the circumferential sidewall of the rotating shaft 21. One end of the rotating sleeve 22 in the axial direction abuts against the limiting part 211, thereby positioning the rotating sleeve 22 in the axial direction. The limiting part 211 can be a protrusion structure or an annular limiting boss, or the rotating shaft 21 can be formed as a stepped shaft, with the shoulder on the stepped shaft forming the limiting part 211.

[0056] Furthermore, in this embodiment, as Figure 4 and Figure 5 As shown, the circumferential sidewall of the portion of the rotating shaft 21 that extends beyond the outer side of the rotating sleeve 22 has an annular groove 212. That is, after the rotating sleeve 22 is fitted onto the rotating shaft 21, the portion of the rotating shaft 21 that extends out of the rotating sleeve 22 has an annular groove 212. The rotating assembly 20 also includes a limiting member 23 disposed in the annular groove 212 and a locking member 24 mounted on the rotating shaft 21. The limiting member 23 can be an annular gasket. A portion of the limiting member 23 extends out of the annular groove 212 and protrudes from the sidewall of the rotating shaft 21, so that the limiting member 23 forms a protruding structure on the rotating shaft 21. The limiting member 23 abuts against the other end of the rotating sleeve 22 in the axial direction.

[0057] The locking element 24 can be a spring locking washer or a retaining ring. The locking element 24 is located on the side of the limiting element 23 away from the rotating sleeve 22. The limiting element 23 and the locking element 24 cooperate to axially limit the other end of the rotating sleeve 22, preventing the rotating sleeve 22 from moving up and down along the extension direction of the rotating shaft 21, thereby ensuring stable support for the auxiliary water tank 50.

[0058] Furthermore, in this embodiment, such as Figures 1 to 4 As shown, a support portion 121 extending horizontally is formed on the second support member 12. The auxiliary water tank 50 is installed on the support portion 121. Specifically, the support portion 121 includes a bottom support plate 1211 and a side limiting plate 1212. The bottom support plate 1211 is formed as a horizontally arranged plate structure and is located below the auxiliary water tank 50 to ensure that the auxiliary water tank 50 is placed stably. The side limiting plate 1212 is formed as a vertically arranged plate structure and is located above the bottom support plate 1211. The side limiting plate 1212 surrounds at least part of the circumferential sidewall of the auxiliary water tank 50, thereby limiting the horizontal displacement of the auxiliary water tank 50, improving the load-bearing stability of the support portion 121 on the auxiliary water tank 50, and preventing the auxiliary water tank 50 from falling off the bottom support plate 1211 due to vibration or impact.

[0059] Furthermore, in this embodiment, as Figure 3 and Figure 4As shown, the rotatable auxiliary water tank mounting structure also includes a first buffer 41, which can be a vibration-damping sponge. The first buffer 41 is disposed on the side of the bottom support plate 1211 and / or the side limiting plate 1212 facing the auxiliary water tank 50, thereby protecting the auxiliary water tank 50 under vibration or impact and preventing damage to the auxiliary water tank 50 that could affect engine performance. Preferably, the bottom support plate 1211 and the side limiting plate 1212 are both provided with the first buffer 41 on the side facing the auxiliary water tank 50 to improve the reliability and effectiveness of the protection.

[0060] In this embodiment, as Figure 2 and Figure 3 As shown, the outer wall of the auxiliary water tank 50 has a recessed snap-fit ​​groove 51; the second support member 12 has a snap-fit ​​part 122 that can extend into the snap-fit ​​groove 51. The snap-fit ​​part 122 is formed as a bent plate-like structure. The snap-fit ​​part 122 extends into the snap-fit ​​groove 51 so that the second support member 12 and the auxiliary water tank 50 are snapped and fixed, thereby improving the stability of the second support member 12 in supporting the auxiliary water tank 50.

[0061] Furthermore, such as Figure 2 and Figure 3 As shown, a second buffer 42 is provided on the surface of the snap-fit ​​part 122. The second buffer 42 can also be made of shock-absorbing sponge, so as to avoid damage to the auxiliary water tank 50 by the snap-fit ​​part 122 under vibration or impact.

[0062] It should be noted that both the first buffer 41 and the second buffer 42 can be fixed to the second support 12 by adhesive.

[0063] The rotatable auxiliary water tank mounting structure of this utility model includes a first support member, a second support member, a rotating component, and fasteners. The first support member is mounted on a structural bracket, and the auxiliary water tank is mounted on the second support member. The rotating component is disposed between the first and second support members, allowing the first and second support members to be rotatably connected. Thus, when the engine needs maintenance or repair, the auxiliary water tank can be rotated, providing more space for engine maintenance or repair without disassembling the auxiliary water tank, saving time and effort, and facilitating operation. One of the first and second support members has a connecting portion; the other of the first and second support members has a connecting hole, through which the fasteners pass and are detachably connected to the connecting portion. After maintenance or repair work is completed, the auxiliary water tank is rotated to its original position and locked by the fasteners, thereby fixing the installation position of the auxiliary water tank and meeting usage requirements.

[0064] The second aspect of this utility model provides an engineering machine that includes the rotatable auxiliary water tank mounting structure as described above, and thus has all the beneficial effects of the rotatable auxiliary water tank mounting structure, which will not be repeated here.
