Description

Technical Field

[0001] This utility model relates to the field of mining transportation equipment technology, and in particular to the field of mining vehicles for transporting ore and earthwork. Specifically, it relates to an intermediate bracket for assembling a wide-body mining dump truck. Background Technology

[0002] Currently, mining wide-body dump trucks, especially large-tonnage vehicles, have a large number of parts on the market. Due to the compact frame structure of mining wide-body dump trucks, the installation of parts is difficult and time-consuming. Moreover, many parts require the cooperation of multiple people to install properly.

[0003] Currently, to address the difficulty of assembling components in large-tonnage wide-body mining dump trucks, most manufacturers weld mounting brackets for various components directly onto the chassis. They also increase the number of assembly workers to improve production efficiency. However, this approach has the following significant drawbacks:

[0004] 1. The frame itself is already a complex part, and the manufacturing process is very complicated. Adding many mounting brackets to the frame further increases the difficulty of frame production.

[0005] 2. The mounting brackets for various components are directly welded to the vehicle frame, making it difficult to remove them during later maintenance and wasting more manpower.

[0006] 3. When assembling parts, assemblers need to crawl under the frame to install them, which is not only time-consuming and labor-intensive, but also greatly reduces safety. In addition, it often requires multiple people to cooperate in the installation, which wastes labor costs. Utility Model Content

[0007] Therefore, the purpose of this utility model is to design an intermediate bracket for assembling wide-body mining dump trucks. The bracket for placing electrical components, wiring harnesses, and hydraulic pipes is fixedly mounted on this intermediate bracket, allowing for assembly of these components and pipes at the edge of the main assembly line. This avoids affecting the production efficiency of the main assembly line, provides ample space at the line edge, eliminates the need to crawl inside the vehicle frame for work, and improves safety. The intermediate bracket, after installing the electrical equipment, is then installed entirely on the vehicle frame. This solves the problems of numerous and complex parts in existing large-tonnage wide-body mining dump trucks, improving assembly efficiency and reducing the need for multiple assembly personnel. Furthermore, through structural design, this intermediate bracket boasts high structural strength, ease of processing, light weight, low cost, simple assembly, and good applicability, facilitating its widespread application.

[0008] This utility model provides an intermediate bracket for assembling a wide-body mining dump truck, comprising: a bracket body, on which an electrical equipment bracket is fixedly mounted, and on which electrical components and wiring harnesses required for production and assembly are installed; during the production and assembly of the wide-body mining dump truck, the intermediate bracket is fixedly mounted on the frame of the wide-body mining dump truck.

[0009] During vehicle production and assembly, electrical components can be installed onto intermediate brackets at the edge of the main production line, and then the intermediate brackets with the electrical components installed can be assembled onto the vehicle frame as a whole.

[0010] Preferably, the intermediate bracket is fixed to the frame with bolts, which facilitates disassembly during later maintenance.

[0011] Since electrical components are assembled separately on the side of the main production line, it does not affect the efficiency of the main production line. At the same time, the space on the side of the main production line is spacious, so assemblers do not need to crawl into the frame to work, which greatly improves safety. One person can complete the assembly.

[0012] Furthermore, the electrical equipment bracket includes: a hybrid motor bracket, a superstructure motor bracket, a high-pressure filter bracket, a gear pump bracket, and a wiring harness fixing bracket; the hybrid motor, superstructure motor, high-pressure filter, gear pump bracket, and wiring harness fixing bracket are respectively mounted on the hybrid motor bracket, superstructure motor, high-pressure filter, gear pump, vehicle wiring harness (such as high-voltage line) and hydraulic oil pipe.

[0013] During vehicle production, the hybrid motor, superstructure motor, high-pressure filter, and gear pump can be pre-installed onto intermediate brackets on the main production line. Then, the intermediate brackets with these electrical components installed are assembled as a whole onto the vehicle frame. Because the hybrid motor, superstructure motor, high-pressure filter, and gear pump are assembled separately on the main production line, the efficiency of the main production line is not affected. The electrical equipment brackets also include wiring harness mounting brackets. Wiring harnesses (such as high-voltage lines) and hydraulic lines on the vehicle can be fixedly mounted on these brackets, thus avoiding the need to directly weld the wiring harness mounting brackets onto the vehicle frame and reducing the difficulty of frame manufacturing.

[0014] Furthermore, the hybrid motor bracket, the superstructure motor bracket, the high-pressure filter bracket, the gear pump bracket, and the wiring harness fixing bracket are respectively welded to the bracket body.

[0015] The hybrid motor bracket, superstructure motor bracket, high-pressure filter bracket, gear pump bracket, and wiring harness fixing bracket are all welded to the bracket body to form an intermediate bracket. The process is simple and fast. Welding not only forms a strong connection, but also improves the sealing of the connection.

[0016] The hybrid motor, superstructure motor, high-pressure filter, and gear pump are pre-assembled onto the intermediate bracket at the edge of the main production line. This avoids assembling these parts in the narrow space of the vehicle frame, improving safety, greatly increasing assembly efficiency, and eliminating the need for multiple people to cooperate in assembly, thus saving on the number of assembly personnel. At the same time, it avoids affecting the production efficiency of the main production line.

[0017] Furthermore, the intermediate bracket is threadedly fixed to the vehicle frame.

[0018] Specifically, the intermediate bracket is connected to the frame by bolts, which makes assembly simple and disassembly convenient for later maintenance.

[0019] Furthermore, the hybrid motor bracket, the superstructure motor bracket, the high-pressure filter bracket, and the wiring harness fixing bracket are located on the upper surface of the bracket body, and the gear pump bracket is located on the lower surface of the bracket body.

[0020] The hybrid motor, superstructure motor, high-pressure filter, vehicle wiring harness, and hydraulic oil pipes are installed on the upper part of the intermediate bracket, which facilitates real-time monitoring and inspection of these electrical devices by assembly workers; the gear pump is installed on the lower part of the intermediate bracket, which saves the overall area of ​​the intermediate bracket and reduces manufacturing costs.

[0021] Furthermore, the hybrid motor bracket and the upper motor bracket are located on the same side of the upper surface of the bracket body, while the high-pressure filter bracket and the wiring harness fixing bracket are located on the other two sides of the upper surface of the bracket body, respectively.

[0022] The intermediate bracket places the high-voltage filter and wiring harness (high-voltage line) away from the hybrid motor and the superstructure motor, avoiding interference and ripple between the voltage in the motor and the high voltage in the wiring harness and the filter, thus improving the anti-interference performance between electrical equipment.

[0023] Furthermore, the gear pump bracket is located directly below the wire harness fixing bracket.

[0024] Because the wiring harness fixing bracket can fix the hydraulic oil pipe while fixing the wiring harness, the installation position of the gear pump and the fixing position of the hydraulic oil pipe are set at close range, which facilitates the assembly of hydraulic equipment.

[0025] Furthermore, the bracket body, hybrid motor bracket, upper motor bracket, high-pressure filter bracket, gear pump bracket, and wiring harness fixing bracket are all formed from sheet metal parts.

[0026] Sheet metal processing saves metal materials, has a simple processing technology, reduces production costs, saves production costs, has low environmental pollution, and has high structural strength, light weight, and is easy to handle and install, thus reducing production and assembly costs.

[0027] Furthermore, the bracket body, hybrid motor bracket, superstructure motor bracket, high-pressure filter bracket, gear pump bracket, and wiring harness fixing bracket are all made of Q235 carbon steel plate.

[0028] The carbon content of Q235 carbon steel is generally between 0.12% and 0.2%. Q235 carbon steel has good weldability. First, the low carbon content gives Q235 carbon steel good plasticity and toughness, making it less prone to brittle fracture after welding. Second, Q235 carbon steel has strong resistance to the heat-affected zone of the weld, which can effectively avoid welding deformation and weld defects. In addition, Q235 carbon steel can also be joined by conventional welding methods such as manual arc welding, gas shielded welding, and CO2 gas shielded welding. The welding process is relatively simple and convenient.

[0029] Furthermore, the thickness of the bracket body is ≥4mm, and the thickness of the hybrid motor bracket, the upper motor bracket, the high-pressure filter bracket, the gear pump bracket, and the wiring harness fixing bracket are all ≥3mm.

[0030] Because the main bracket body bears a large load, its design thickness is relatively large. However, each electrical equipment bracket on the main bracket body bears a relatively small load on its own electrical components, wiring harnesses, and hydraulic pipes, so its design thickness is relatively small to ensure welding quality and structural connection strength.

[0031] Compared with the prior art, the beneficial effects of this utility model are:

[0032] The intermediate bracket provided by this utility model for assembling wide-body mining dump trucks has a simple and reasonable structure with strong overall integrity. The bracket for placing electrical components, wiring harnesses, and hydraulic pipes is fixedly mounted on this intermediate bracket, allowing for assembly of these components and pipes at the edge of the main assembly line. This avoids affecting the production efficiency of the main assembly line. The spacious edge space eliminates the need to crawl inside the vehicle frame, improving safety. The intermediate bracket, after installing the electrical equipment, is then installed as a whole onto the vehicle frame. This effectively solves the problems of numerous and complex parts in existing large-tonnage wide-body mining dump trucks, improving assembly efficiency. Assembly can be completed by one person, saving on assembly personnel. Furthermore, through structural design, this intermediate bracket boasts high structural strength, ease of processing, light weight, low cost, simple assembly, and good applicability, making it promising for widespread application.

[0044] Example

[0045] This utility model embodiment provides an intermediate bracket for assembling a wide-body dump truck for mining, see [link to relevant documentation]. Figure 1 As shown, an electrical equipment bracket is fixedly installed on the bracket body 1. The electrical equipment bracket includes: a hybrid motor bracket 2, an upper motor bracket 3, a high-pressure filter bracket 4, a gear pump bracket 5, and a wire harness fixing bracket 6.

[0046] In this embodiment, the hybrid motor bracket 2, the superstructure motor bracket 3, the high-pressure filter bracket 4, the gear pump bracket 5, and the wiring harness fixing bracket 6 are respectively welded to the bracket body 1. Welding all of the hybrid motor bracket 2, superstructure motor bracket 3, high-pressure filter bracket 4, gear pump bracket 5, and wiring harness fixing bracket 6 to the bracket body 1 to form an intermediate bracket is a simple and quick process that not only forms a strong connection but also improves the sealing performance of the connection.

[0047] The hybrid motor bracket 2, the upper motor bracket 3, the high-pressure filter bracket 4, and the wiring harness fixing bracket 6 are all located on the upper surface of the bracket body 1, while the gear pump bracket 5 is located on the lower surface of the bracket body 1. Figure 1 , Figure 2 As shown, the hybrid motor, superstructure motor, high-pressure filter, vehicle wiring harness, and hydraulic oil pipes are installed on the upper part of the intermediate bracket, which facilitates real-time monitoring and inspection of these electrical devices by the assembler; the gear pump is installed on the lower part of the intermediate bracket, which saves the overall area of ​​the intermediate bracket and reduces manufacturing costs.

[0048] The hybrid motor bracket 2 and the upper motor bracket 3 are located on the same side of the upper surface of the bracket body 1, while the high-voltage filter bracket 4 and the wiring harness fixing bracket 6 are located on the other two sides of the upper surface of the bracket body 1, respectively. This intermediate bracket places the high-voltage filter and the wiring harness (high-voltage line) away from the hybrid motor and the upper motor, avoiding interference and ripple between the voltage in the motor and the high voltage in the wiring harness and between the filter, thus improving the anti-interference performance between electrical equipment.

[0049] The gear pump bracket 5 is located directly below the wiring harness fixing bracket 6. Because the wiring harness fixing bracket fixes both the wiring harness and the hydraulic oil pipe, the close proximity of the gear pump installation position and the hydraulic oil pipe fixing position facilitates the assembly of hydraulic equipment.

[0050] The bracket body 1, hybrid motor bracket 2, upper motor bracket 3, high-pressure filter bracket 4, gear pump bracket 5, and wiring harness fixing bracket 6 are all made of sheet metal. Sheet metal processing saves metal materials, simplifies the processing technology, reduces production costs, saves on production costs, and has low environmental pollution. Sheet metal parts have high structural strength, are lightweight, and are easy to handle and install, reducing production and assembly costs. The bracket body 1, hybrid motor bracket 2, upper motor bracket 3, high-pressure filter bracket 4, gear pump bracket 5, and wiring harness fixing bracket 6 are all made of Q235 carbon steel plate. Q235 carbon steel has good plasticity and toughness, and is not prone to brittle fracture after welding. The thickness of bracket body 1 is 4mm, and the thickness of hybrid motor bracket 2, upper motor bracket 3, high-pressure filter bracket 4, gear pump bracket 5, and wiring harness fixing bracket 6 is 3mm. Due to the large load-bearing capacity of bracket body 1, its design thickness is relatively large. The electrical equipment brackets on the bracket body 1 each bear relatively small loads on their respective electrical components, wiring harnesses, and hydraulic oil pipes, so the design thickness is relatively small to ensure welding quality and structural connection strength.

[0051] The hybrid motor, superstructure motor, high-pressure filter, gear pump, vehicle wiring harness, and hydraulic oil pipes are respectively installed on the hybrid motor bracket 2, superstructure motor bracket 3, high-pressure filter bracket 4, gear pump bracket 5, and wiring harness fixing bracket 6. During the production and assembly of the mining wide-body dump truck, the intermediate bracket with these electrical components installed is assembled onto the chassis as a whole. In this embodiment, the intermediate bracket is installed on the chassis using a threaded bolt connection, simplifying the assembly process and facilitating disassembly for later maintenance.

[0052] Because the hybrid motor, superstructure motor, high-pressure filter, and gear pump can be pre-installed on the intermediate bracket at the edge of the main production line (see...). Figure 3 , Figure 4 As shown in the diagram, this avoids assembling the above parts in the narrow space of the vehicle frame, thus improving safety. Since the hybrid motor, superstructure motor, high-pressure filter, and gear pump are assembled separately on the side of the main production line, it does not affect the efficiency of the main production line, greatly improving assembly efficiency and saving the number of assembly workers by eliminating the need for multiple people to work together.

[0053] Because the electrical equipment bracket also includes a wiring harness fixing bracket 6, which can be used to fix and install the electrical components and wiring harnesses required for production and assembly, including wiring harnesses (such as high-voltage lines) and hydraulic oil pipes on the vehicle, this avoids directly welding the wiring harness fixing bracket to the chassis, reducing the difficulty of chassis manufacturing. Since the electrical components are assembled separately on the side of the main production line, the space on the side of the main production line is spacious, and the assembler does not need to crawl into the chassis to work, greatly improving safety. One person can complete the assembly work.

[0054] The intermediate bracket for assembling wide-body mining dump trucks in this embodiment has a simple and reasonable structure with strong overall integrity. The bracket for placing electrical components, wiring harnesses, and hydraulic pipes is fixedly mounted on this intermediate bracket, allowing for assembly of these components and pipes at the edge of the main assembly line. This avoids affecting the production efficiency of the main assembly line. The spacious edge space eliminates the need to crawl inside the vehicle frame, improving safety. The intermediate bracket, after installing the electrical equipment, is then installed as a whole onto the vehicle frame. This effectively solves the problems of numerous and complex parts in existing large-tonnage wide-body mining dump trucks, improving assembly efficiency. Assembly can be completed by one person, saving on assembly personnel. Furthermore, the structural design makes this intermediate bracket strong, easy to process, lightweight, low-cost, simple to assemble, and highly adaptable.

[0055] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
