Description

Technical Field

[0001] This utility model belongs to the technical field of mining dump trucks, specifically relating to a battery box sealing plate fixing bracket and battery box for mining dump trucks. Background Technology

[0002] Mining dump trucks are off-highway dump trucks used for transporting materials such as coal and sand in off-highway field environments. Currently, electric-driven mining dump trucks are becoming more common, using batteries as power sources, which solves pollution problems and meets green energy-saving requirements. The battery box bracket plays a crucial role in the mining industry.

[0003] The battery box bracket is used to secure the battery pack, ensuring its stable and secure installation on the mining dump truck and protecting it from damage in harsh mining environments. The battery box cover plate is fixed around the battery box bracket, serving multiple functions including battery protection, sealing and dust prevention, heat insulation, and improved safety.

[0004] Currently, most mining dump trucks have welding nuts inside the battery box bracket, and the sealing plate is fixed to the battery box bracket with bolts. This method is convenient for installation.

[0005] However, during maintenance of mining dump trucks, repeated disassembly and reassembly of the battery box cover can lead to stripping of the threads, causing the cover to become unsecured or only secured with a few bolts, exposing the battery pack to the harsh mining environment. This makes the battery box susceptible to water or dust ingress, resulting in decreased battery pack performance. Furthermore, this method is also susceptible to welding defects; misalignment between the welded nuts and the holes on the battery box bracket can cause stripping during assembly. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a battery box sealing plate fixing bracket and battery box for mining dump trucks, which solves the problem of easy stripping of threads after repeated disassembly of the battery box sealing plate. The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A fixing bracket for the battery box sealing plate of a mining dump truck, comprising: The two first support beams have their inner and outer sides folded outwards to form the first end edge and the second end edge, respectively. Two second support beams are connected at both ends to the two ends of the first support beams to form a frame structure. The inner and outer sides of the second support beams are folded outward to form a third end edge and a fourth end edge, respectively. The outer surfaces of the first end edge and the third end edge are located on the same plane of the first mounting surface, which is used to connect and fix to the front side of the battery box. The outer surfaces of the second and fourth end edges are located on the same plane of the second mounting surface, which is used to connect and fix them to the sealing plate.

[0007] Compared with existing technologies, the above technical solutions have the following beneficial effects: A frame structure formed by two first support beams and two second support beams is fitted to the front of the battery box. The inner side of the frame structure connects to the battery box via a first and third end edge forming a first mounting surface, while the outer side connects to the sealing plate via a second and fourth end edge forming a second mounting surface. This allows the sealing plate to be connected to the battery box via a fixing bracket, eliminating the need for welding nuts inside the battery box frame and avoiding the impact of misalignment caused by the welding process. During maintenance, only the side connected to the sealing plate needs to be disassembled, making installation convenient. While bolts and nuts connect the sealing plate to the fixing bracket, stripping of the threads may occur after repeated disassembly and reassembly. If stripping occurs, the bolts and nuts should be replaced promptly, ensuring proper installation of the sealing plate and preventing the battery pack from being exposed to the harsh mining environment.

[0008] Based on the above technical solution, the embodiments of this application can be further improved as follows: In one embodiment, a plurality of first reinforcing plates are provided at intervals between the first end edge and the second end edge, and a plurality of second reinforcing plates are provided at intervals between the third end edge and the fourth end edge.

[0009] In one embodiment, the inner side of the first support beam is provided with an avoidance slot for matching with the vertical beam in the middle of the front side of the battery box.

[0010] In one embodiment, the system further includes two third support beams, which are respectively disposed on both sides of the clearance slot. The inner and outer sides of the third support beams are folded up to be flush with the first mounting surface and the second mounting surface.

[0011] In one embodiment, the first support beam has mounting portions at both ends that fold towards the second support beam. The mounting portions have elongated holes and are engaged between the third and fourth end edges of the second support beam, thus connecting and fixing them to the second support beam.

[0012] This utility model also discloses a battery box for a mining dump truck, which includes: A box-shaped support frame, wherein a recessed stepped frame is provided on the front side of the box-shaped support frame; As described above, the first mounting surface of the fixed bracket is connected and fixed to the stepped frame of the box bracket by fasteners. A sealing plate, wherein the sealing plate is connected and fixed to the second mounting surface of the fixed bracket by fasteners around its perimeter; Several protective plates are installed on other surfaces of the housing support that are different from the sealing plate.

[0013] In one embodiment, the box support is provided with a plurality of support frames, which are arranged vertically at intervals to divide the interior of the box support into a plurality of layers. A short diagonal brace is provided between the side of the support frame and the rear side of the box support, and a reinforcing rib is provided at the corner between the side of the support frame and the front side of the box support.

[0014] In one embodiment, a BMS support frame is provided on the support frame, and a U-shaped fixing frame is provided on the support frame near the BMS support frame. Limiting plates are provided on the support frame on both sides of the U-shaped fixing frame.

[0031] Example 1 like Figure 1-4 As shown, the present invention provides a fixing bracket for a battery box sealing plate 15 of a mining dump truck, which includes two first support beams 1 and two second support beams 2.

[0032] Two first support beams 1 are arranged vertically and horizontally as crossbeams. The inner and outer sides of the first support beams 1 are folded outward to form the first end edge 3 and the second end edge 4, respectively. Two second support beams 2 are arranged horizontally and horizontally as vertical beams 26. The two ends of the two second support beams 2 are connected to the two ends of the two first support beams 1 to form a frame structure. The inner and outer sides of the second support beams are folded outward to form the third end edge 5 and the fourth end edge 6, respectively.

[0033] Specifically, the first support beam 1 and the second support beam 2 can be implemented using channel steel, with the inner and outer sides of the channel steel used as end edges.

[0034] Wherein, the outer surfaces of the first end edge 3 and the third end edge 5 are located on the same plane of the first mounting surface, that is, the inner surfaces of the first support beam 1 and the second support beam 2 serve as the first mounting surface for connection and fixation with the front side of the battery box. The outer surfaces of the second end edge 4 and the fourth end edge 6 are located on the same plane as the second mounting surface, that is, the outer surfaces of the second support beam 2 and the first support beam 1 serve as the second mounting surface for connection and fixation with the sealing plate 15.

[0035] A frame structure formed by two first support beams 1 and two second support beams 2 is fitted to the front of the battery box. The inner side of the frame structure is connected to the battery box via a first mounting surface formed by a first end edge 3 and a third end edge 5. The outer side is connected and fixed to the sealing plate 15 via a second mounting surface formed by a second end edge 4 and a fourth end edge 6. This allows the sealing plate 15 to be connected to the battery box via the fixing bracket, eliminating the need for the welding nuts inside the battery box frame and avoiding the impact of misalignment caused by the welding process. During maintenance, only the side connected to the sealing plate 15 needs to be disassembled, making installation convenient. While bolts and nuts connect the sealing plate 15 to the fixing bracket, stripping of the threads may occur after repeated disassembly and reassembly. If stripping occurs, the bolts and nuts should be replaced promptly. The sealing plate 15 can be installed normally, preventing the battery pack from being exposed to the harsh mining environment.

[0036] During installation, mounting holes are made at intervals on the first end edge 3, the second end edge 4, the third end edge 5, and the fourth end edge 6, and connected to the battery box and the cover plate 15 by fasteners such as bolts.

[0037] Specifically, in order to strengthen the inner and outer edge strength of the first support beam 1 and the second support beam 2, a plurality of first reinforcing plates 7 are provided at intervals between the first edge 3 and the second edge 4, and a plurality of second reinforcing plates 8 are provided at intervals between the third edge 5 and the fourth edge 6.

[0038] Specifically, the first reinforcing plate 7 and the second reinforcing plate 8 are both positioned to avoid the mounting hole position on the opening edge. In particular, the reinforcing plates and the mounting holes are staggered.

[0039] To ensure proper installation, the inner side of the first support beam 1 is provided with an avoidance slot 9 for matching with the vertical beam 26 in the middle of the front side of the battery box. The avoidance slot 9 partially cuts off the first end edge 3 of the inner side of the first support beam 1.

[0040] To ensure the robustness of the frame structure and the secure installation with the battery box, two third support beams 10 are also included. The two third support beams 10 are respectively set on both sides of the clearance slot 9, which serves to strengthen the structural strength at the clearance notch on the first support beam 1. The inner and outer sides of the third support beam 10 are folded up to be flush with the first mounting surface and the second mounting surface. Here, the inner and outer sides of the third support beam 10 are connected and fixed to the battery box and the sealing plate 15 respectively. The connection method is the same as that of the first support beam 1 and the second support beam 2, and will not be described again here.

[0041] To ensure the connection redundancy of the frame structure, the first support beam 1 is provided with mounting parts 11 at both ends that fold towards the second support beam 2. The mounting parts 11 are provided with elongated holes 12. The mounting parts 11 are inserted into the second support beam 2 between the third end edge 5 and the fourth end edge 6 at both ends, and are connected and fixed to the second support beam 2. The second support beam 2 is provided with mounting holes at both ends that correspond to the elongated holes 12. Bolts are fitted in the mounting holes. The mounting parts 11 are connected and fixed to the elongated holes 12 and the ends of the second support beam 2 by bolts. The setting of the elongated holes 12 allows the length of each side of the frame structure to be slightly adjusted to fit the battery box, and at the same time, it is easy to maintain good concentricity with the holes on the battery box, which facilitates disassembly and assembly.

[0042] Example 2 like Figure 5-8 As shown, this embodiment also discloses a battery box for a mining dump truck, which includes: a box support 13, a fixed support as in Embodiment 1, a sealing plate 15, and a protective plate 16. The box support 13 is a three-dimensional rectangular frame. The sealing plate 15 is used to correspond to the front side of the box support 13, which is convenient for frequent disassembly and assembly. The protective plate 16 corresponds to other sides and does not need to be frequently disassembled and assembled.

[0043] The front side of the box bracket 13 is provided with a recessed step frame 14, which is used to match the fixed bracket.

[0044] The first mounting surface of the fixed bracket is connected and fixed to the step frame 14 of the box bracket 13 by fasteners such as bolts. The step frame 14 forms a step with the box bracket 13 in the circumferential direction. When the inner side of the fixed bracket is connected to the step surface, it is partially embedded in the box bracket 13.

[0045] The sealing plate 15 is connected and fixed to the second mounting surface of the fixed bracket, i.e. the outer side of the fixed bracket, by fasteners. When disassembling, only the sealing plate 15 needs to be removed.

[0046] Several protective plates 16 are installed on other surfaces of the box bracket 13 that are different from the sealing plate 15, such as the top surface, bottom surface, left and right sides and the back.

[0047] Furthermore, the enclosure support 13 is provided with several support frames 17, which are spaced vertically to divide the interior of the enclosure support 13 into several layers. Each support frame 17 is formed by interlacing and welding several horizontal beams and vertical beams. The support frames 17 are connected and fixed to the vertical beams 26 of the enclosure support 13 around their perimeter, dividing the interior of the enclosure support 13 into multiple layers, which facilitates the placement and fixing of multiple batteries.

[0048] To enhance the structural strength of the support frame 17 and the box support 13, a short diagonal brace 18 is provided between the side of the support frame 17 and the rear side of the box support 13, and a reinforcing rib plate 19 is provided at the corner between the side of the support frame 17 and the front side of the box support 13.

[0049] In one embodiment, a long diagonal brace 23 is also provided on the outside of the box body. The long diagonal brace 23 is provided on both sides of the box body, and the two ends of the long diagonal brace 23 are fixedly connected to the box body. The long diagonal brace 23 is pressed against the outside of the protective plate 16.

[0050] To facilitate the installation and fixation of the BMS connected to the battery, a BMS support frame 20 is provided on the support frame 17. The BMS support frame 20 is higher than the support frame 17. A U-shaped fixing frame 21 is provided on the support frame 17 near the BMS support frame 20. Limiting plates 22 are provided on the support frame 17 on both sides of the U-shaped fixing frame 21. The U-shaped fixing frame 21 and the limiting plates 22 can facilitate the fixing of the battery on the support frame 17.

[0051] To improve the structural strength of the sealing plate 15, several protective beams 24 are arranged in a crisscross pattern on the outer side of the sealing plate 15, and a handle 25 is provided on the outer side of the sealing plate 15. The handle 25 facilitates the removal and assembling of the sealing plate 15.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
