[0002] In open-pit mining operations, high-capacity mobile equipment is required to transport the extracted mineral resources, such as bridge transfer conveyors, mobile transfer conveyors, and concrete placing booms. Currently, tracked gearboxes, as the core drive components of mobile barge transport equipment in open-pit mining and bulk material conveying, are mostly driven by hydraulic motors. However, these tracked gearboxes often suffer from low efficiency, poor control precision, and poor responsiveness, failing to adequately meet the needs of modern mining and thus increasing mining costs. Utility Model Content

[0003] The purpose of this utility model is to provide a tracked gearbox transmission assembly and a tracked walking device.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] The tracked gearbox transmission assembly includes:

[0006] The first transmission unit includes a housing, an input shaft, and an output shaft.

The output shaft is arranged perpendicular to the input shaft, and one end of the output shaft extends into the housing and is connected to the input shaft in a transmission manner. Rotation of the input shaft can drive the output shaft to rotate.

[0007] The second transmission unit includes a connecting shaft, a planetary mechanism, and a drive unit. One end of the connecting shaft is connected to the end of the output shaft that extends out of the housing, and the other end of the connecting shaft is connected to the planetary mechanism. The drive unit is connected to the planetary mechanism, and the rotation of the connecting shaft is transmitted to the drive unit through the planetary mechanism.

[0026] like Figures 1 to 2 As shown, this utility model provides a tracked gearbox transmission assembly, which includes a first transmission unit 1 and a second transmission unit 2. The first transmission unit 1 includes a housing 11, an input shaft 12, and an output shaft 13. One end of the input shaft 12 is connected to a drive motor, and the other end of the input shaft 12 extends into the housing 11. The output shaft 13 is arranged perpendicular to the input shaft 12, and one end of the output shaft 13 extends into the housing 11 and is drivenly connected to the input shaft 12. Rotation of the input shaft 12 can drive the output shaft 13 to rotate. The second transmission unit 2 includes a connecting shaft 22, a planetary mechanism, and a drive unit 23. One end of the connecting shaft 22 is drivenly connected to the end of the output shaft 13 that extends out of the housing 11, and the other end of the connecting shaft 22 is drivenly connected to the planetary mechanism. The drive unit 23 is drivenly connected to the planetary mechanism, and rotation of the connecting shaft 22 is transmitted to the drive unit 23 through the planetary mechanism.

[0027] In this embodiment, since one end of the input shaft 12 and one end of the output shaft 13 are connected in transmission within the housing 11, and the input shaft 12 is used to connect to the drive motor, the drive motor can drive the output shaft 13 to rotate through the input shaft 12. Furthermore, since the output shaft 13 and the input shaft 12 are arranged perpendicularly, the first transmission unit 1 can change the direction of power transmission while transmitting power, thereby improving the installation flexibility of the tracked walking gearbox transmission assembly. Since the connecting shaft 22 of the second transmission unit 2 is connected in transmission with the output shaft 13 of the first transmission unit 1, and the connecting shaft 22 is also connected to the drive unit 23 through a planetary mechanism, the rotation of the connecting shaft 22 can be transmitted to the drive unit 23 through the planetary mechanism, enabling the second transmission unit 2 to achieve normal power output, thereby driving the tracked walking device to operate. This tracked gearbox transmission assembly has a simple structure and high transmission efficiency. It realizes the power transmission and connection between the first transmission unit 1 and the second transmission unit 2 through the connecting shaft 22. It can output the power from the drive motor to the tracked device through the drive part 23 of the second transmission unit 2, thereby optimizing and redistributing the speed and torque. Furthermore, since the input shaft 12 and the output shaft 13 of the first transmission unit 1 are perpendicular, the tracked transmission device can also change the direction of power transmission, thereby improving the installation flexibility and practicality of the tracked gearbox transmission assembly.

[0028] In this embodiment, the second transmission unit 2 further includes a fixed base 21, which provides a fixed platform for the entire second transmission unit 2. The fixed base 21 is fixedly connected to the tracked walking device, and the planetary mechanism is rotatably connected to the fixed base 21. The planetary mechanism is a three-stage planetary transmission structure, with adjacent planetary transmission structures rotating and engaging. The specific composition and operating principle of each stage of the planetary transmission structure are common knowledge in the art and will not be described in detail here. The drive unit 23 includes a fixedly connected drive gear ring 231 and a bearing seat 232, wherein the drive gear ring 231 is wound around the most... On the planetary gears of the outermost planetary transmission mechanism, the bearing housing 232 is rotatably sleeved on the fixed seat 21 and fixedly connected to the drive gear ring 231 by bolts. A connecting ring plate is wound around the bearing housing 232, and a screw hole is opened on the connecting ring plate for fixed connection with the drive sprocket of the track walking device. When the connecting shaft 22 rotates under the drive of the output shaft 13, the planetary transmission structure of each stage of the second transmission unit 2 also rotates, and drives the outermost drive gear ring 231 to rotate. The drive gear 231 then drives the bearing housing 232 to rotate, thereby realizing power output.

[0029] The transmission connection between the input shaft 12 and the output shaft 13 can be configured according to actual conditions, as long as perpendicular transmission between the input shaft 12 and the output shaft 13 can be achieved. For example, such as... Figure 1 As shown, an input bevel gear 121 is provided on the input shaft 12, and an output bevel gear 131 is provided on the output shaft 13. The input bevel gear 121 and the output bevel gear 131 mesh with each other. The input bevel gear 121 and the output bevel gear 131 can change the transmission direction of the input shaft 12, so that the first transmission unit 1 does not need to be connected to the output shaft 13 along the axial direction of the input shaft 12. Therefore, the axial dimension of the tracked gearbox transmission assembly is reduced while meeting the normal torque output requirements, making the structure of the tracked gearbox transmission assembly more compact and flexible.

[0030] like Figure 1 and Figure 2 As shown, a heat dissipation rib plate 111 is provided on the outer surface of the housing 11. The heat dissipation rib plate 111 protrudes from the outer surface of the housing 11, and multiple heat dissipation rib plates 111 are provided. The heat dissipation rib plate 111 can increase the heat dissipation area of ​​the housing 11, thereby facilitating heat dissipation of the tracked gearbox transmission assembly. Specifically, the specific structure of the heat dissipation rib plate 111 can be set according to the actual situation, for example, a rectangular or triangular structure. In this embodiment, the heat dissipation rib plate 111 protrudes from the outer surface of the housing 11 and is integrally formed with the housing 11. The heat dissipation rib plate 111 has a cuboid structure, and multiple heat dissipation rib plates 111 are arranged in parallel.

[0031] The transmission connection between the output shaft 13 and the connecting shaft 22 can be set according to the actual situation, as long as the connecting shaft 22 can rotate synchronously with the output shaft 13. In this embodiment, the output shaft 13 is provided with a spline, the connecting shaft 22 is provided with a spline sleeve, and the spline is limited to the spline sleeve, that is, the output shaft 13 and the connecting shaft 22 are keyed together.

[0032] like Figure 1 As shown, a first bearing is fixedly installed inside the housing 11, and the input shaft 12 is rotatably engaged with the housing 11 through the first bearing; there are two first bearings, which are spaced apart along the length of the input shaft 12.

[0033] Similarly, a second bearing is fixedly installed inside the housing 11, and the output shaft 13 is rotatably engaged with the housing 11 through the second bearing; there are two second bearings, which are spaced apart along the length of the output shaft 13.

[0034] This embodiment also provides a tracked walking device, which includes a drive motor, a drive sprocket, a track, and the aforementioned tracked walking gearbox transmission assembly. The output end of the drive motor is driven and connected to the input shaft 12, and the drive sprocket is fixedly connected to the drive unit 23. The drive sprocket is driven and connected to the track. In this embodiment, the drive sprocket is sleeved on the drive gear ring 231 of the second transmission unit 2 and is fixedly connected to the bearing seat 232 by bolts. The drive sprocket also meshes with the track. Therefore, when the drive unit 23 rotates, it will drive the track to rotate through the drive sprocket, thereby driving the mobile device to move.

[0035] In this embodiment, the power output by the drive motor can be transmitted to the drive sprocket through the first transmission unit 1 and the second transmission unit 2, thereby driving the track to rotate. This tracked walking device is used for high-capacity mobile equipment in open-pit mining operations, such as bridge transfer conveyors, mobile transfer conveyors, and fan-shaped concrete placing booms; this tracked walking device can be driven by a drive motor, has a compact structure, high transmission efficiency, and strong practicality.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
