Description

Technical Field

[0001] This application belongs to the field of operating machinery technology, specifically relating to a fuel tank mounting structure for operating machinery and the operating machinery itself. Background Technology

[0002] Currently, the fuel tank of a loader is usually bolted directly to the rear frame. The fuel tank and the rear frame are only connected by bolts. The weight of the entire fuel tank and the forces it experiences during operation are almost entirely concentrated on these bolts. For example, when the loader is traveling on uneven roads, the fuel tank will be subjected to impact forces, vibrations, and inertial forces from all directions. The dynamic load on the fuel tank will increase significantly. These loads will cause the bolts to bear large shear forces and tensile forces. Long-term use may cause the bolts to loosen, fatigue, or even break, thereby affecting the fixed stability of the fuel tank. Utility Model Content

[0003] In view of at least one of the above-mentioned defects or deficiencies in the prior art, this application provides a fuel tank mounting structure for operating machinery and operating machinery, which can reduce the installation difficulty of fuel tank and improve the stability of fuel tank.

[0004] To achieve the above objectives, the first aspect of this application provides a fuel tank mounting structure for operating machinery, the fuel tank mounting structure comprising:

[0005] The frame includes multiple side plates and multiple support plates, the multiple side plates being connected in sequence to enclose a fuel tank mounting area, and the multiple support plates being arranged at intervals along the circumference of the fuel tank mounting area on the inner sidewalls of the multiple side plates.

[0006] A fuel tank, disposed in the fuel tank mounting area and comprising a fuel tank body and a plurality of tank support plates, wherein the plurality of tank support plates are spaced apart on the outer peripheral wall of the fuel tank body, and the fuel tank body is placed on a plurality of support plates via the plurality of tank support plates; and

[0007] Fastening components are used to lock the housing support plate and the corresponding support plate.

[0008] In some embodiments, the inner end faces of the plurality of support plates abut against the outer peripheral wall of the tank body.

[0009] In some embodiments, the plurality of side panels include left and right side panels that are spaced apart from each other, and the plurality of support plates include left and right support plates respectively disposed on the left and right side panels. The fuel tank includes a left tank support plate group and a right tank support plate group respectively disposed on the left and right outer side walls of the fuel tank body. The left tank support plate group includes a plurality of left tank support plates arranged in sequence at intervals, and the right tank support plate group includes a plurality of right tank support plates arranged in sequence at intervals. The plurality of left tank support plates are pressed against the left support plate, and the plurality of right tank support plates are pressed against the right support plate.

[0010] In some embodiments, the fuel tank includes a plurality of tank pads disposed on the outer peripheral wall of the fuel tank body, and a plurality of tank support plates are respectively fixedly connected to the plurality of tank pads.

[0011] In some embodiments, the tank pad is welded to the outer peripheral wall of the tank body, and the tank support plate is welded to the corresponding tank pad.

[0012] In some embodiments, the fuel tank includes a plurality of stiffening plates, which are respectively connected between the corresponding plurality of tank support plates and the outer peripheral wall of the fuel tank body.

During the process, there is no need to manually lift the fuel tank, which effectively reduces the installation difficulty.

[0023] Detailed Implementation

[0024] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0025] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0026] like Figure 1 and Figure 2 As shown, a first exemplary embodiment of this application provides a fuel tank mounting structure for operating machinery. The fuel tank mounting structure includes a frame, a fuel tank, and fastening components. The frame includes multiple side plates 1 and multiple support plates 2. The side plates 1 are connected end-to-end to enclose a fuel tank mounting area, i.e., the frame is hollow to form the fuel tank mounting area. The multiple support plates 2 are arranged at intervals along the circumference of the fuel tank mounting area on the inner side walls of the side plates 1, and all support plates 2 can be arranged horizontally. The fuel tank is located in the fuel tank mounting area and includes a fuel tank body 3 and multiple tank support plates 4. The multiple tank support plates 4 are arranged at intervals on the outer peripheral wall of the fuel tank body 3. Correspondingly, the support plates 4 can also be arranged horizontally. The fuel tank body 3 is placed on the multiple support plates 2 by the multiple tank support plates 4. The fastening components are used to lock the tank support plates 4 to the corresponding support plates 2.

[0027] This application does not limit the specific structural shape of the fuel tank body 3, for example it can be as follows: Figure 1 The cuboid shown can also be a cylinder or an irregular shape, as long as it can be installed in the frame and placed stably on the multiple support plates 2 by multiple box support plates 4.

[0028] Therefore, during installation, the fuel tank can be lowered as a whole onto multiple support plates 2 of the vehicle frame using hoisting equipment. Multiple tank support plates 4 are then naturally aligned with the support plates 2, and a rigid connection between the fuel tank and the vehicle frame is achieved by fastening components. The ring-shaped distribution of the support plates 2 evenly distributes the weight of the fuel tank to multiple side plates 1 of the vehicle frame, avoiding localized stress concentration and achieving distributed load transfer, significantly improving impact resistance. Furthermore, the mating surface contact positioning method used during hoisting simplifies the installation process, reduces manual labor intensity, and enhances safety, preventing the fuel tank from detaching and causing injury.

[0029] In one alternative embodiment, such as Figure 2 As shown, the inner end faces of multiple support plates 2 abut against the outer peripheral wall of the fuel tank body 3. In other words, the multiple support plates 2 extend from the side plate 1 into the frame, and the area enclosed by the multiple support plates 2 is limited to the fuel tank body 3. In this way, the inner end faces of the support plates 2 can provide lateral restraint to the fuel tank body 3, suppressing the shaking of the fuel tank body 3 and improving the stability of the fuel tank body 3. Furthermore, the inner end faces of the multiple support plates 2 can be processed into contact surfaces that match the curvature of the outer wall of the fuel tank body 3. The contact area uses an elastic buffer material layer, and the curved surface fit design can enhance the restraint on the fuel tank body 3. The buffer layer can absorb vibration energy and reduce impact wear between metal parts.

[0030] like Figure 1 As shown, when the fuel tank body 3 is a rectangular box, the fuel tank mounting structure can adopt a symmetrical support layout. Specifically, multiple side plates 1 include left and right side plates that are spaced apart from each other, multiple support plates 2 include left and right support plates respectively disposed on the left and right side plates, and the fuel tank includes a left tank support plate group and a right tank support plate group respectively disposed on the left and right outer side walls of the fuel tank body 3. The left tank support plate group includes multiple left tank support plates arranged at intervals in sequence, and the right tank support plate group includes multiple right tank support plates arranged at intervals in sequence. The multiple left tank support plates are pressed against the left support plate, and the multiple right tank support plates are pressed against the right support plate. It can be seen that the symmetrical layout of the fuel tank mounting structure balances the lateral load and can improve the structural stability.

[0031] In one alternative embodiment, such as Figure 1 As shown, the fuel tank includes multiple tank pads 5 disposed on the outer peripheral wall of the fuel tank body 3, and multiple tank support plates 4 are respectively fixedly connected to the multiple tank pads 5. By providing tank pads 5 for transition connection on the outer wall of the fuel tank body 3, the tank support plates 4 can be connected to the fuel tank body 3 through the tank pads 5. The tank pads 5 can prevent stress concentration on the tank support plates 4 from damaging the outer wall of the fuel tank body 3, protect the structural integrity of the fuel tank body 3, improve the local load-bearing capacity of the fuel tank body 3, and the stress distribution design can delay the propagation of fatigue cracks.

[0032] Furthermore, the tank pad 5 is welded to the outer peripheral wall of the tank body 3, and the tank support plate 4 is welded to the corresponding tank pad 5. Thus, the tank pad 5 and the tank body 3, as well as the tank support plate 4 and the corresponding tank pad 5, are connected by welding, making the connection between them more stable. In addition, the tank pad 5 can disperse the welding stress and effectively protect the tank body 3.

[0033] In one alternative embodiment, such as Figure 2 As shown, the fuel tank includes multiple stiffening plates 6, which are respectively connected between the corresponding multiple tank support plates 4 and the outer peripheral wall of the fuel tank body 3. By setting the inclined stiffening plates 6 between the tank support plates 4 and the fuel tank body 3, a triangular support structure is formed. The stiffening plates 6 can change the stress transmission path, reduce the stress peak at the root of the tank support plates 4, improve the bending stiffness of the tank support plates 4, suppress the deformation of the tank support plates 4, and improve the overall structural strength and load-bearing capacity.

[0034] Furthermore, two stiffening plates 6 are provided on the top of each tank support plate 4. The stiffening plates 6 are welded to the outer peripheral wall of the tank support plate 4 and the tank body 3 using CO2 gas shielded welding to improve the stability of the stiffening plates 6.

[0035] In one alternative embodiment, such as Figure 1 As shown, the fastening assembly uses a bolt and nut assembly, which includes bolt 7 and nut 8. Bolt 7 passes through and fixes the tank support plate 4, support plate 2, and nut 8. By cooperating with bolt 7 and nut 8, the stacked tank support plate 4 and support plate 2 are fixed, which can effectively avoid the risk of the fuel tank body 3 falling off and ensure the safety of the fuel tank during installation and use.

[0036] Furthermore, such as Figure 1 As shown, the fastening assembly also includes a sleeve 9, and bolts 7 are sequentially connected to the sleeve 9, the support plate 2, the housing support plate 4, and the nut 8. The diameter of the sleeve 9 can be the same as the diameter of the mounting holes in the support plate 2 and the housing support plate 4. The outer diameter of the sleeve 9 can be set to be larger than the outer diameter of the nut of the bolt 7, so that when the end face of the sleeve 9 is pressed against the support plate 2, the effective contact area can be increased and the stress distribution can be improved.

[0037] A second exemplary embodiment of this application provides a working machine that includes the aforementioned fuel tank mounting structure for working machines. Clearly, the working machine of this exemplary embodiment possesses all the technical effects brought about by the aforementioned fuel tank mounting structure, and therefore will not be described in detail here.

[0038] In practical applications, the fuel tank mounting structure can be used on loaders, the frame can be the rear frame of the loader, and the fuel tank can be the rear fuel tank of the loader.
