Description

Technical Field

[0001] This utility model relates to the technical field of mining dump trucks, and in particular to a hydraulic cylinder crossbeam and a mining dump truck. Background Technology

[0002] With key technologies for pure electric vehicles not yet fully mature, hybrid mining trucks, which combine the range advantages of fuel-powered vehicles with the environmentally friendly characteristics of electric drive, are becoming an effective solution for the industry's energy transformation.

[0003] Current hybrid mining trucks, by innovatively integrating an internal combustion engine and an electric motor as dual power sources, demonstrate significant advantages in complex mining conditions. Their powertrain system can intelligently switch drive modes according to load changes, using fuel power to ensure output during heavy-load uphill climbing and charging the battery through an energy recovery system during downhill braking. This optimizes energy consumption and significantly reduces pollutant emissions.

[0004] However, the integration and layout of the power battery pack and key components of the control system are facing severe challenges. Due to the specific operating scenarios of mining trucks, the overall vehicle layout needs to coordinate the placement of large-capacity battery modules, intelligent control units, and traditional transmission devices within a limited space. This places higher demands on the structural design, heat dissipation management, and maintenance convenience of the power compartment. Current hybrid mining trucks, due to the large number of batteries and controllers and the limited space in the vehicle, face relatively difficult equipment layout. Utility Model Content

[0029] Example 1

[0030] like Figure 1-3 As shown, a hydraulic cylinder crossbeam includes: a support 1, a pad 2, a limiting block 3, a mounting plate 4, and a lower support assembly 5. The support 1 is used to connect to the vehicle frame and has a mounting position for placing the hydraulic cylinder. The pad 2 is connected to the support 1 and is located directly below the lower support 6 of the hydraulic cylinder. The limiting block 3 is connected to the support 1 and is used to limit the lower support 6 to the hydraulic cylinder mounting position. The mounting plate 4 is connected to the support 1 and is used to install a controller. The lower support assembly 5 is connected to the lower end of the support 1 and is also used to connect to the vehicle frame.

[0031] Specifically, such as Figure 1 As shown, the support 1 includes: a base plate 101, a side plate 102, and a first reinforcing plate 103. The base plate 101 is used to connect with the vehicle frame, the side plates 102 are connected to the upper two sides of the base plate 101, and the first reinforcing plate 103 is connected between the side plates 102. The structural strength of the support 1 is improved by the first reinforcing plate 103.

[0032] Specifically, such as Figure 1 As shown, there are two side plates 102, which are respectively connected to the front and rear sides of the base plate 101 (front in the direction of the vehicle head and rear in the direction of the vehicle tail). The mounting position is located in the middle of the base plate 101. There are two first reinforcing plates 103, which are respectively located on the left and right sides of the mounting position. There are four limiting blocks 3, with two blocks connected to each side plate 102. The pad block 2 is made of channel steel and is connected to the base plate 101. The purpose of setting the pad block 2 is to prevent the connecting bolts of the lower cylinder bracket 6 from loosening, which would cause the pressure to act directly on the upper edge of the lower bracket 6.

[0033] Specifically, such as Figure 1 As shown, the base plate 101 forms a downward-opening U-shaped connection area for connecting to the vehicle frame. The side plate 102 has an inverted U-shaped notch at its lower end, and the side plate 102 is connected to the base plate 101 through the notch. The inverted U-shaped structure of the base plate 101 facilitates the connection between the support 1 and the vehicle frame and improves the connection strength. The side plate 102, with its matching structure, surrounds the base plate 101, thereby improving the overall structural strength.

[0034] Specifically, such as Figure 1 As shown, the side plate 102 extends outward with a support arm, which is used to connect the mounting plate 4. The width of the mounting plate 4 is greater than the spacing between the side plates 102. By positioning the mounting plate 4 on the outside of the support 1, interference between the structure of the mounting plate 4 and the structure of the support 1 is avoided, making it easier for the structure of the support 1 to adapt to the cylinder structure, and making the structure of the mounting plate 4 more compatible with the controller.

[0035] Specifically, such as Figure 3 As shown, the mounting plate 4 includes a first folded edge 401 and a second folded edge 402. The first folded edge 401 is bent upward and connected to the side plate 102; the second folded edge 402 is bent downward and connected to the side plate 102. The first folded edge 401 and the second folded edge 402 are located on the left and right sides of the mounting plate 4, respectively. The first folded edge 401 is located on the side closer to the oil cylinder, and the second folded edge 402 is located on the side farther away from the oil cylinder. The folded edges improve the structural strength and connection stability of the mounting plate 4.

[0036] Specifically, such as Figure 3 As shown, the cylinder crossbeam also includes a second reinforcing plate 7 and a third reinforcing plate 8. The second reinforcing plate 7 is disposed between the side plates 102 and is connected to the side plates 102 and the mounting plate 4 respectively. The third reinforcing plate 8 is located on the other side of the side plates 102 relative to the second reinforcing plate 7 and is connected to the side plates 102 and the mounting plate 4 respectively, thereby improving the structural strength of the mounting plate 4.

[0037] Specifically, such as Figure 3 As shown, the lower support assembly 5 includes a first beam 501 and a second beam 502. The first beam 501 is connected between the longitudinal beams of the frame, and the second beam 502 is connected between the longitudinal beams. Both the first beam 501 and the second beam 502 are made of U-shaped channel steel. The opening of the first beam 501 faces downwards, and the opening of the second beam 502 faces the first beam 501. The second beam 502 has a through hole for hydraulic lines to pass through. The first beam 501 and the second beam 502 form a support structure at the lower end of the bracket, improving the overall structural strength. Simultaneously, the first beam 501 provides protection on the side of the second beam 502, improving the protection of the pipelines within the second beam 502.

[0038] Specifically, such as Figure 1 As shown, the cylinder crossbeam also includes a protective cover 9, which is connected to the mounting plate 4. The protective cover 9 is used to protect the controller and improve the safety of the controller.

[0039] When in use, this type of hydraulic cylinder crossbeam can accommodate the installation of the controller and radiator by additionally configuring the mounting plate 4, thereby saving space on the vehicle and facilitating the installation of other equipment. At the same time, the structural design of the support 1 and the mounting plate 4 gives this type of crossbeam a good strength structure. After being installed on the frame, the structure is stable and has strong resistance to deformation. The setting of the limit block 3 facilitates the positioning and installation of the lower support 6 of the hydraulic cylinder, and the setting of the pad block 2 can protect the lower support 6, thereby improving the ease of use of this type of crossbeam.
