Description

Technical Field

[0001] The present application relates to the technical field of mining machinery, and in particular to an oil tank protection structure and an underground electric scraper. Background Art

[0002] Compared to underground internal combustion LHDs, underground electric LHDs have a higher level of safety protection, improving safety during underground operations. Underground electric LHDs typically have a hydraulic oil tank mounted on their frame, while lithium batteries are installed inside. A leak in the hydraulic oil tank could cause the hydraulic oil to flow into the lithium battery, potentially causing a safety accident. Therefore, a tank protection structure is required to protect the tank and prevent potential risks such as hydraulic oil leaks.

[0003] The fuel tank is typically located at the front end of the scraper's rear frame. Since scrapers typically feature a centrally articulated structure, the fuel tank is susceptible to scraping against the front frame, roadway sidewalls, and other components during steering. Therefore, a chamfered surface is typically provided to prevent this. However, the chamfered surface of the fuel tank increases the complexity of its design, manufacturing, and assembly. The challenge lies in ensuring that the chamfered surface of the fuel tank shroud is aligned with the tank's, eliminating any misalignment, seams, or uneven heights to maintain an aesthetically pleasing appearance and minimize production and assembly difficulties.

DETAILED DESCRIPTION

[0025] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0029] One aspect of the present application provides a fuel tank protection structure, such as Figure 1 and Figure 2 As shown, one of the preferred embodiments includes a frame 1, on which a first mounting plate 11 and a second mounting plate 12 are provided; one end of the frame 1 is connected to the vehicle frame 3 through the first mounting plate 11, and the other end is connected to the fixing rod 2 through the second mounting plate 12; at the same time, in order to make the frame 1 fit more closely to the fuel tank 4, a corner 13 is provided on the frame so that the frame 1 can be arranged along the outer contour of the fuel tank 4, and the position of the corner 13 corresponds to the position of the chamfer 41 on the fuel tank 4, so that the installation of the frame 1 and the fuel tank 4 is more closely fitted.

[0030] Specifically, such as Figure 2 As shown, the frame 1 is in an “L” shape, the first mounting plate 11 is arranged on the short side of the frame 1 , and the second mounting plate 12 is arranged on the long side of the frame 1 .

[0031] It should be noted that when the shape of the oil tank 4 changes, the shape of the frame 1 will also change. The above-mentioned long side and short side are not absolute concepts. In some other embodiments, the first mounting plate 11 can be set on the long side of the frame 1, and the second mounting plate 12 can also be set on the short side of the frame 1.

[0032] Further, such as Figure 3 and Figure 4 As shown, the first mounting plate 11 is provided with a first mounting hole 110, and the second mounting plate 12 is provided with a second mounting hole 120. The first mounting plate 11 is connected to the fixing rod 2 through the first mounting hole 110, and the second mounting plate 12 is connected to the vehicle frame 3 through the second mounting hole 120. Installing the frame 1 through the mounting holes can facilitate the subsequent replacement of the frame 11.

[0033] It should be noted that the number of the first mounting holes 110 and the second mounting holes 120 is not fixed and can be set according to the weight of the fuel tank 4 and actual needs.

[0034] Specifically, such as Figure 3 and Figure 4As shown, the first mounting hole 110 and the second mounting hole 120 are both oblong holes, so that when the bolt is inserted into the hole, it can move along the long axis direction of the first mounting hole 110 and the second mounting hole 120. In addition, the long axis of the first mounting hole 110 is perpendicular to the long axis of the second mounting hole 120.

[0035] It is understandable that the fuel tank 4 is installed below the frame 1. In the prior art, the mounting hole is circular, and the frame 1 cannot be adjusted in position after installation, which may leave a gap between the fuel tank 4 and the frame 1. On bumpy roads, the fuel tank 4 may hit the frame 1 under the action of inertia and be damaged.

[0036] To avoid the above situation, in some embodiments, Figure 3 As shown, the long axis of the first mounting hole 110 is perpendicular to the horizontal plane of the frame 1, so that the frame 1 can move up and down. The specific implementation method is as follows: the frame 1 is first movably connected to the frame 3 via bolts, and then the frame 1 is moved downward to allow the bolts and the first mounting hole 110 to slide relative to each other. When the frame 1 is in contact with the fuel tank 4, the bolts are tightened again to eliminate the gap between the frame 1 and the fuel tank 4. The frame 1 can be removed by reversing the above steps.

[0037] In this embodiment, if Figure 1 and Figure 4 As shown, the plane where the fixing rod 2 is located is parallel to the plane where the frame 1 is located, and the long axis of the second mounting hole 120 is set to be parallel to the plane where the frame 1 is located, so that the fixing rod 2 can move left and right within the plane where the frame 1 is located, thereby eliminating the misalignment or misalignment between the frame 1 and the oil tank 4.

[0038] Further, such as Figure 1 and Figure 2 As shown, the frame 1 is provided with two stoppers 14. The upper end surface of the frame 1 is partially folded downward to form an inclined surface. One end of the stopper 14 is located at the intersection of the upper end surface and the inclined surface of the frame 1, and the other end is located at the opening below the frame 1. The frame 1 can be bent along the stopper 14. After the frame 1 is bent, welding is performed on the stopper 14, which not only enhances the structural strength of the frame 1 but also reduces the manufacturing difficulty of the frame 1. In addition, the provision of the stopper 14 ensures that the frame 1 has no seams after bending, further enhancing the aesthetics of the product.

[0039] It should be noted that the number of the stop line 14 is at least one, which can be specifically set according to the number of times the frame 1 needs to be folded or the number of chamfers 41 on the fuel tank 4 .

[0040] In this embodiment, if Figure 1 and Figure 2As shown, a support plate 15 is mounted on the frame 1. A cover plate 100 is mounted on both the support plate 15 and the fixing rod 2. One side of the cover plate 100 is hinged to the fixing rod 2 or the support plate 15. The cover plate 100 is movably mounted on the upper end surface of the frame 1. The cover plate 100 is opened and closed via a hinged structure. Opening the cover plate 100 allows access to the fuel tank 4. Closing the cover plate 100 covers the fuel tank 4, preventing debris from passing through the frame 1 and improving the safety of the fuel tank 4.

[0041] It should be noted that the number of cover plates 100 can be one or more, and the specific number of cover plates 100 can be set according to actual needs.

[0042] Further, such as Figure 1 As shown, there are multiple cover plates 100. A pair of cover plates 100 is connected by a connector 200, while a single cover plate 100 is connected to the frame 1 by bolts. The opening and closing of the cover plates 100 are controlled by the connector 200 or the bolts. A handle 300 is installed on the cover plates 100 to reduce the difficulty of opening the cover plates 100.

[0043] It should be noted that the connecting member 200 can be a latch or a buckle, and it only needs to ensure that the two cover plates 100 that cooperate with each other can form an integrated structure through the connecting member 200.

[0044] In this embodiment, if Figure 5 As shown, a plurality of ribs 16 are provided inside the frame 1 to improve the rigidity of the frame 11 and ensure that the impact force when the cover 100 is closed will not cause the frame 1 to deform.

[0045] Another aspect of the present application provides an underground electric scraper, a preferred embodiment of which includes an underground electric scraper body and the above-mentioned fuel tank protection structure, the fuel tank protection structure is installed on the underground electric scraper through the frame 3, and the fuel tank protection structure is used to improve the safety of the underground electric scraper.

[0046] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
