[0028] Please refer to Figures 1 to 3 , which shows a platform support assembly for a mining dump truck provided in an embodiment of the present utility model, for installation on a vehicle frame 1, including:

[0029] A fixing component 2, the fixing component 2 includes a first support pipe 21, a first fixing pipe 22, a second fixing pipe 23 and a second support pipe 24. The first support pipe 21 and the second support pipe 24 are arranged at intervals. The first fixing pipe 22 and the second fixing pipe 23 are respectively connected to both ends of the first support pipe 21 and the second support pipe 24, and the first fixing pipe 22 and the second fixing pipe 23 are arranged at intervals;

[0030] A connecting component 3, the connecting component 3 is arranged on the fixing component 2, and the connecting component 3 is used to install the platform support assembly of the mining dump truck on the outer side of the vehicle frame 1 along the width direction of the vehicle frame 1; and

[0031] Install component 4. Install component 4 is arranged on the fixed component 2. Install component 4 includes a first mounting bracket 41 for installing the cab and a second mounting bracket 42 for installing the deck.

[0032] Please refer to Figure 3 , the first support pipe 21 is preferably a circular pipe. In this embodiment, the connecting component 3 is the first support pipe 21, which is connected through the connecting hole between the first support pipe 21 and the vehicle frame 1. At the same time, the outer diameter of the first support pipe 21 corresponds to the diameter of the connecting hole, so that after the first support pipe 21 is inserted into the connecting hole, the first support pipe 21 can be coaxial with the connecting hole. Along the axis of the first support pipe 21, a first fixing pipe 22 and a second fixing pipe 23 are provided on the first support pipe 21. Preferably, the second support pipe 24 is arranged parallel to the first support pipe 21, and both ends of the second support pipe 24 are connected to the first fixing pipe 22 and the second fixing pipe 23 respectively, which can strengthen the stability of the connection between the first fixing pipe 22 and the second fixing pipe 23.

[0033] As Figure 1 shown, on the side of the first fixing pipe 22 away from the first support pipe 21, a first mounting bracket 41 is installed, and on the side of the second fixing pipe 23 away from the first support pipe 21, a first mounting bracket 41 is also installed. Preferably, both first mounting brackets 41 are flat plates, forming a flat mounting surface. Both first mounting brackets 41 are used to install the cab. Preferably, the connection method used for installing the cab is threaded connection. At the same time, a plurality of second mounting brackets 42 are also installed at the end of the first fixing pipe 22 away from the first support pipe 21 and at the end of the second fixing pipe 23 away from the first support pipe 21. In this embodiment, taking four second mounting brackets 42 as an example, two second mounting brackets 42 are installed on each of the first fixing pipe 22 and the second fixing pipe 23, and the deck is installed through the second mounting brackets 42.

[0034] In this embodiment, by installing the fixed component 2 on the side connection hole of the vehicle frame 1 along the width direction of the vehicle frame 1 through the connecting component 3, the limitation caused by the width of the longitudinal beam can be avoided; the fixed component 2 can extend along the direction away from the vehicle frame 1, increasing the installation space.

[0035] In one embodiment, the connecting component 3 includes a guide pipe 32 connected to the first support pipe 21. The guide pipe 32 is inserted into the first support pipe 21 from one end of the first support pipe 21, and at least part of the guide pipe 32 extends out of one side of the first support pipe 21. The first support pipe 21 is connected to the vehicle frame 1 by inserting the guide pipe 32 into the connecting hole of the vehicle frame 1.

[0036] As Figure 1As shown, a guide tube 32 is connected to the right end of the first support tube 21, and the guide tube 32 is also a circular tube. The outer diameter of the guide tube 32 corresponds to the inner diameter of the first support tube 21, so the guide tube 32 can be inserted into the first support tube 21 and fixedly connected to the first support tube 21. At the same time, the guide tube 32 extends outward along the axis of the first support tube 21, and the outward extending end of the guide tube 32 is used to be inserted into the connection hole of the vehicle frame 1, and the outer diameter of the guide tube 32 corresponds to the diameter of the connection hole.

[0037] Because the outer diameter of the guide tube 32 corresponds to the inner diameter of the first support tube 21 and the guide tube 32 is inserted into the first support tube 21, the guide tube 32 is coaxial with the first support tube 21. Also, because the outer diameter of the guide tube 32 corresponds to the diameter of the connection hole and the guide tube 32 is inserted into the connection hole of the vehicle frame 1, the guide tube 32 is coaxial with the connection hole. Therefore, the coaxiality of the first support tube 21 and the connection hole is ensured through the guide tube 32, making the positioning of the first support tube 21 accurate.

[0038] If the first support tube 21 is used for positioning connection with the connection hole, then when the first support tube 21 needs to increase its volume and installation area, the first support tube 21 will be restricted by the connection hole, and the increased volume is limited. In this embodiment, the first support tube 21 is positioned and connected through the guide tube 32, and it is only necessary to keep the size of the guide tube 32 corresponding to that of the connection hole. Then the first support tube 21 is not restricted by the connection hole and can continue to increase.

[0039] Therefore, in this embodiment, through the connection by the guide tube 32, the first support tube 21 can be increased in volume without being restricted by the connection hole.

[0040] It can be understood that in other embodiments, the first support tube 21 can also be connected to the vehicle frame 1 in other ways, such as directly connecting the first support tube 21 to the vehicle frame 1 through bolts.

[0041] In one embodiment, the connection assembly 3 further includes a convex block 31. The convex block 31 is provided at one end of the fixing assembly 2 facing the vehicle frame 1, and the convex block 31 is aligned and connected with the connection block 11 of the vehicle frame 1 to fixedly connect the fixing assembly 2 to the vehicle frame 1.

[0042] Please refer to Figure 1 and Figure 2 , in this embodiment, the convex block 31 is installed on the first support tube 21, and the convex block 31 is installed on the surface of the first support tube 21 where the first fixing tube 22 and the second fixing tube 23 are installed, that is, the convex block 31, the first fixing tube 22 and the second fixing tube 23 are all installed above the first support tube 21. At the same time, the connection block 11 is also arranged above the connection hole.

[0043] When the first support tube 21 is inserted into the connection hole, the first support tube 21 drives the convex block 31 to move towards the vehicle frame 1 together until the convex block 31 abuts against the vehicle frame 1. Then rotate the first support tube 21 to drive the convex block 31 to align with the connection block 11 through the first support tube 21. Both the convex block 31 and the connection block 11 are provided with screw holes. After alignment, the convex block 31 and the connection block 11 are fixedly connected by bolts.

[0044] In this embodiment, by aligning and connecting the convex block 31 with the connection block 11, it is ensured that after the fixing assembly 2 is connected to the vehicle frame 1, both the first fixing tube 22 and the second fixing tube 23 are vertically upward, ensuring the accuracy of the positioning of the first fixing tube 22 and the second fixing tube 23. In this embodiment, the cab is installed through the first fixing tube 22 and the second fixing tube 23, so it is necessary to make the first fixing tube 22 and the second fixing tube 23 vertically upward. In other embodiments, the position of the connection block 11 can be adjusted according to actual installation requirements, that is, the orientations of the first fixing tube 22 and the second fixing tube 23 after the convex block 31 and the connection block 11 are connected can be adjusted.

[0045] In one embodiment, the second fixing tube 23 includes opposite first end 231 and second end 232. The first end 231 is connected to one end of the first support tube 21 away from the connection assembly 3, and the second end 232 is inclined towards the side away from the first fixing tube 22.

[0046] As Figure 1 shown, along the axial direction of the first support tube 21, the part away from the vehicle frame 1 is the second fixing tube 23. The lower end of the second fixing tube 23 is the first end 231, and the upper end is the second end 232. Among them, the first end 231 is fixedly connected to the first support tube 21, and the second end 232 is fixedly connected to the first mounting bracket 41. The entire second fixing tube 23 is arranged obliquely and is inclined towards the side away from the first fixing tube 22, that is, inclined towards the direction away from the vehicle frame 1. Therefore, the second end 232 is farther away from the vehicle frame 1 than the first end 231.

[0047] When the position of the upper end of the first fixing tube 22 remains unchanged, if the second fixing tube 23 is inclined towards the direction away from the vehicle frame 1, the distance between the second end 232 and the upper end of the first fixing tube 22 can be increased, thereby increasing the installation space. When facing the requirements of different installation positions, the inclination degree of the second fixing tube 23 can be adjusted. In this embodiment, the included angle between the long side of the second fixing tube 23 and the axis of the first support tube 21 is designed to be 72° to make the overall structure stable.

[0048] In one embodiment, the cross-section of at least one of the first fixing tube 22, the second fixing tube 23, and the second support tube 24 is rectangular, and the second fixing tube 23 is formed by welding two U-shaped plates in alignment with each other.

[0049] As shown Figure 4 As shown, the upper and lower U-shaped plates are aligned with each other and symmetrically arranged. Welding is performed at the position where the two U-shaped plates abut, so as to fixedly connect the two U-shaped plates. And the bending angles of the two U-shaped plates are both right angles. After the two U-shaped plates are aligned and connected, they enclose a rectangle. However, it is not limited to this. The second fixing pipe 23 can also directly select square steel. Since the second fixing pipe 23 is composed of U-shaped plates, it has a flat outer surface, so that more installation space can be provided.

[0050] In this embodiment, the second fixing pipe 23 is formed by aligning and welding two U-shaped plates, which can avoid the problem that square steel is difficult to purchase. At the same time, the standard sizes of square steel have been designed at the time of factory. When facing installation requirements of different sizes, it is difficult to adjust. In this embodiment, however, the U-shaped plate has strong plasticity and its size is not limited, and it can be changed and adjusted according to actual needs. And the procurement of U-shaped plates is more convenient, and they can also be selected according to actual needs when purchasing. Therefore, in this embodiment, the second fixing pipe 23 is formed by aligning and welding two U-shaped plates, which not only improves the applicability but also saves costs. Not only the second fixing pipe 23, but also the first fixing pipe 22, the second support pipe 24 and the rest of the components can be made in this way.

[0051] In one embodiment, the mining dump truck platform support assembly further includes a protective layer 5 connected to the fixing assembly 2, and the protective layer 5 shields the fixing assembly 2; alternatively, the installation assembly 4 further includes a third installation bracket 43 for installing an air filter, a fourth installation bracket 44 for installing a lubricating pipe assembly, a fifth installation bracket 45 for installing an intake pipe, a sixth installation bracket 46 for installing a heat dissipation pipe, a seventh installation bracket 47 for installing a platform, and an eighth installation bracket 48 for installing a connecting rod. The third installation bracket 43 and the fourth installation bracket 44 are connected to the side of the protective layer 5 facing away from the first fixing pipe 22, the fifth installation bracket 45 is connected to the second support pipe 24, the sixth installation bracket 46 is connected to the side of the protective layer 5 close to the first fixing pipe 22, the seventh installation bracket 47 is connected to the end of the protective layer 5 close to the first support pipe 21, and the eighth installation bracket 48 is connected to one end of the second support pipe 24 close to the first fixing pipe 22.

[0052] As shown Figure 2 As shown, a protective layer 5 is provided on the back of the first fixing pipe 22 and the second fixing pipe 23, and the protective layer 5 covers the back of the fixing assembly 2. The bottom of the protective layer 5 is connected to the first support pipe 21, then extends upward, and covers the first fixing pipe 22 and the second fixing pipe 23. The protective layer 5 is connected between the first fixing pipe 22 and the second fixing pipe 23, which can provide support and protection for the first fixing pipe 22 and the second fixing pipe 23, and can prevent dust, sand and gravel from passing through between the first fixing pipe 22 and the second fixing pipe 23.

[0053] As Figure 2 shown, since the protective layer 5 covers the fixing component 2, the protective layer 5 can provide a relatively large mounting plane. On the back surface of the protective layer 5, there are provided two third mounting brackets 43 for mounting the air filter and a fourth mounting bracket 44 for mounting the lubricating pipe assembly. The two third mounting brackets 43 are arranged in parallel for mounting the air filter. The fourth mounting bracket 44 is disposed below the third mounting bracket 43, and the fourth mounting bracket 44 is used for mounting the lubricating pipe.

[0054] On the back surface of the protective layer 5, there are also provided two sixth mounting brackets 46 for mounting the heat dissipation pipe. The two sixth mounting brackets 46 are spaced apart on one side of the protective layer 5 close to the first fixing pipe 22, and the heat dissipation pipe is mounted through the two sixth mounting brackets 46. At the same time, at the position where the protective layer 5 is connected to the first support pipe 21, there are also provided two seventh mounting brackets 47 for mounting the platform. The two seventh mounting brackets 47 are spaced apart along the axial direction of the first support pipe 21, and the two seventh mounting brackets 47 are used for mounting the small platform.

[0055] On the front surface of the protective layer 5, the eighth mounting bracket 48 is mounted at the position where the second support pipe 24 is connected to the first fixing pipe 22. After mounting the connecting rod through the eighth mounting bracket 48, it can be connected to the vehicle frame 1 through the connecting rod. On one side of the second support pipe 24 close to the third mounting bracket 43, a fifth mounting bracket 45 is also mounted, so that the intake pipe is mounted through the fifth mounting bracket 45.

[0056] In this embodiment, by integrating a plurality of brackets for mounting different components on the fixing component 2, the mounting space can be saved.

[0057] In one embodiment, the protective layer 5 is provided with a through hole 51. The through hole 51 is located between the two third mounting brackets 43, and the through hole 51 is used for mounting the intake pipe.

[0058] As Figure 2 shown, in order to prevent the passage of dust and grinding wheels, the protective layer 5 covers the entire back surface of the fixing component 2. However, after the air filter is mounted through the two third mounting brackets 43, gas exchange is required. Therefore, a through hole 51 is provided between the two third mounting brackets 43, and the intake pipe passes through the through hole 51 and is connected to the air filter. Preferably, the diameter of the through hole 51 corresponds to the outer diameter of the intake pipe, so that the through hole 51 is tightly connected to the intake pipe, avoiding the generation of gaps and improving the sealing performance. As Figure 1 shown, on the front surface of the platform support assembly of the mining dump truck, a fifth mounting bracket 45 is also provided at a position close to the through hole 51. The fifth mounting bracket 45 is fixedly mounted on the second support pipe 24, and the intake pipe is mounted through the fifth mounting bracket 45.

[0059] In one embodiment, there are two first mounting brackets 41. The two first mounting brackets 41 are respectively connected to the end face of the first fixed pipe 22 away from the first support pipe 21 and the end face of the second fixed pipe 23 away from the first support pipe 21, and the two first mounting brackets 41 are in the same plane, which is used to form a mounting surface. The second mounting bracket 42 includes four. The four second mounting brackets 42 are respectively connected to the end of the first fixed pipe 22 away from the first support pipe 21 and the end of the second fixed pipe 23 away from the first support pipe 21.

[0060] As Figure 1 shown, in this embodiment, the end face of the first fixed pipe 22 away from the first support pipe 21 and the end face of the second fixed pipe 23 away from the first support pipe 21 are both in the same plane, so that the mounting plane formed by the first fixed pipe 22 and the second fixed pipe 23 together is a flat plane, which is convenient for installation. Then the two first mounting brackets 41 respectively mounted on the first fixed pipe 22 and the second fixed pipe 23 can also be in the same plane, and can better fit with the cab. However, it is not limited to this, and the relative position between the top surface of the first fixed pipe 22 and the top surface of the second fixed pipe 23 can be adjusted according to the actual installation requirements.

[0061] In one embodiment, the platform support assembly of the mining dump truck further includes a strengthening component 7. The strengthening component 7 includes a first reinforcing rib 71 and a second reinforcing rib 72. The first reinforcing rib 71 is connected between the first fixed pipe 22 and the second fixed pipe 23, and the second reinforcing rib 72 is connected to the protective layer 5 for supporting the protective layer 5. In one embodiment, the width of the first reinforcing rib 71 is greater than the width of the second reinforcing rib 72.

[0062] As Figure 1 shown, the first reinforcing rib 71 is connected between the first fixed pipe 22 and the second fixed pipe 23, and the first reinforcing rib 71 is arranged in parallel with the first support pipe 21 to provide support for the first fixed pipe 22 and the second fixed pipe 23. The first reinforcing rib 71, the first fixed pipe 22, the second fixed pipe 23 and the first support pipe 21 together enclose the main frame of the platform support assembly of the mining dump truck and become the main load-bearing components.

[0063] And the number of the first reinforcing ribs 71 can be appropriately increased or decreased according to the lengths of the first fixed pipe 22 and the second fixed pipe 23. In this embodiment, two first reinforcing ribs 71 are taken as an example to provide sufficient strength for the entire platform support assembly of the mining dump truck.

[0064] At the same time, a second reinforcing rib 72 is also provided between the first fixed pipe 22 and the second fixed pipe 23. The second reinforcing rib 72 is mainly connected to the protective layer 5. Because the gap between the first fixed pipe 22 and the second fixed pipe 23 is relatively large, only two ends of the protective layer 5 are connected to the first fixed pipe 22 and the second fixed pipe 23, and the middle part of the protective layer 5 has no support.

[0065] Therefore, in this embodiment, the second reinforcing rib 72 is connected to the middle of the protective layer 5 to provide support for the protective layer 5. Preferably, there are also multiple second reinforcing ribs 72. The specific number of the second reinforcing ribs 72 can be adjusted according to the actual situation. The larger the gap between the first fixing pipe 22 and the second fixing pipe 23, the more the number of the second reinforcing ribs 72 can be increased, so as to enhance the support for the protective layer 5. In this embodiment, a total of three second reinforcing ribs 72 are provided.

[0066] Since the first reinforcing rib 71 is a component of the main frame of the platform support assembly of the mining dump truck and is the main load-bearing component, while the second reinforcing rib 72 only needs to provide support for the protective layer 5, in this embodiment, the width of the first reinforcing rib 71 is greater than the width of the second reinforcing rib 72. That is, the strength of the first reinforcing rib 71 is greater than the strength of the second reinforcing rib 72, so that the second reinforcing rib 72 can save materials.

[0067] Another embodiment of the present utility model further provides a frame assembly, including a frame 1 and the above-mentioned platform support assembly of the mining dump truck, and the platform support assembly of the mining dump truck is detachably connected to the frame 1 through a connecting component 3.

[0068] After the platform support assembly of the mining dump truck is completed, it is also necessary to perform inspections to test the assembly of the platform support assembly of the mining dump truck and the frame 1. Then, during the assembly test of the platform support assembly of the mining dump truck and the frame 1, the platform support assembly of the mining dump truck does not need to support the rest of the components, and the connection between the platform support assembly of the mining dump truck and the frame 1 does not need to bear too much pressure. Therefore, the platform support assembly of the mining dump truck and the frame 1 can be detachably connected through the connecting component 3.

[0069] At the same time, since the width of the frame 1 will be increased after the platform support assembly of the mining dump truck and the frame 1 are assembled, it is not convenient for transportation.

In this embodiment, after the above-mentioned detachable connection with the frame 1 is realized through the connecting component 3 for preliminary positioning, the connecting component 3 and the frame 1 are fixedly connected by welding to improve the connection stability and the supporting force of the platform support assembly of the mining dump truck.

[0071] Another embodiment of the present utility model further provides a mining dump truck, which includes a vehicle frame 1 and the mining dump truck platform support assembly as described above. The mining dump truck platform support assembly is installed on the outer side of the vehicle frame 1 along the width direction of the vehicle frame 1. The mining dump truck platform support assembly is installed on the side of the vehicle frame 1 through a first support pipe 21 and can extend in a direction away from the vehicle frame 1, so as to provide an increased installation space for installing more components.

[0072] In one embodiment, the mining dump truck includes two mining dump truck platform support assemblies. The two mining dump truck platform support assemblies are arranged on both sides of the vehicle frame 1 along the width direction of the vehicle frame 1, and the mining dump truck platform support assembly is arranged at the front end of the vehicle frame 1.

[0073] In this embodiment, the width direction of the vehicle frame 1 is the width direction of the entire mining dump truck. Installing a mining dump truck platform support assembly on each side of the mining dump truck can meet the basic installation requirements of the mining dump truck. At the same time, since the cab is installed through the mining dump truck platform support assembly, the mining dump truck platform support assembly is arranged at the front end of the vehicle frame 1.

[0074] As described above, the above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
