Description

Technical Field

[0001] This application relates to the field of underground scraper technology, specifically to a connecting seat and a steering device for underground scrapers. Background Technology

[0002] The underground loader includes a front frame and a rear frame. The front frame and the rear frame are connected by a steering device. The steering wheel is connected to the steering pump through the steering device, thereby realizing the steering control of the vehicle so that the front and rear frames can rotate relative to each other within a certain angle range.

[0003] In the steering device of the existing underground loader, there is a connecting seat and a rotating shaft. The connecting seat contains two bearings, and the rotating shaft is located between the two bearings. One end of the rotating shaft that extends out of the connecting seat is connected to the steering pump, and the other end is connected to the steering wheel. The end face of the connecting seat near the steering pump is a flange end face, and there is a transition component between the connecting seat and the steering pump. The flange end face of the connecting seat, the transition component, and the steering pump are connected by bolts, thereby connecting the connecting seat, the steering pump, and the transition component into one unit.

[0004] However, in this type of steering device, when the bearing inside the connecting seat is damaged, the bolts connecting the connecting seat and the transition component need to be removed to separate the connecting seat from the steering pump and the transition component before the bearing can be removed from the connecting seat for maintenance. Therefore, the disassembly and assembly procedure is quite complicated and the maintenance efficiency is extremely low when maintaining the bearing inside the connecting seat.

[0005] Therefore, the connecting seat in the steering device of the existing underground loader has room for further improvement. Utility Model Content

Therefore, the above terms should not be construed as limitations on this application.

[0049] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 3 illustrate.

[0050] First aspect

[0051] This application provides a connecting seat 1, which is used in the steering device of an underground loader for mounting a rotating shaft 5 and connecting to a steering pump 3, so that the steering device can be connected to the steering wheel 2 and the steering pump 3.

[0052] like Figures 1 to 2 As shown, the connecting seat 1 includes a first connecting component 11, a second connecting component 12, and a connecting vertical plate 13. The first connecting component 11 and the second connecting component 12 are arranged parallel to each other along the axial direction. The connecting vertical plate 13 is located on the same side of the first connecting component 11 and the second connecting component 12. The upper end of the connecting vertical plate 13 is connected to the first connecting component 11, and the lower end of the connecting vertical plate 13 is connected to the second connecting component 12. The first connecting component 11 is used to install the bearing assembly 4, and the second connecting component 12 is used to install the steering pump 3. The first connecting component 11 is provided with a first mounting port 114, and the second connecting component 12 is provided with a second mounting port 126. The first mounting port 114 and the second mounting port 126 are coaxially arranged to allow the rotating shaft 5 to pass through. The inner diameter of the first mounting port 114 and the inner diameter of the second mounting port 126 are both larger than the outer diameter of the rotating shaft 5.

[0053] In this embodiment, the first connecting component 11 and the second connecting component 12 are separately arranged. The first connecting component 11 is directly connected to the bearing assembly 4, and the second connecting component 12 is directly connected to the steering pump 3. This means that there is no direct connection or direct limiting relationship between the bearing assembly 4 and the steering pump 3. When maintaining the bearing assembly 4, it is not necessary to disconnect the connection between the connecting seat 1 and the steering pump 3. The bearing assembly 4 can be directly removed from the first connecting component 11, which can realize the maintenance of the bearing assembly 4. This greatly simplifies the maintenance procedure and makes it convenient for staff to repair.

[0054] Furthermore, the first connecting component 11 will be described in more detail; such as Figure 1 , Figure 2 As shown, the first connecting assembly 11 includes a first connecting plate 111 and a mounting plate 112. The first connecting plate 111 has a circular structure and a connection port. The mounting plate 112 has a disc-shaped structure and is installed inside the connection port. The outer wall of the mounting plate 112 fits against the inner wall of the connection port. The mounting plate 112 and the first connecting plate 111 are welded or press-fitted to achieve the connection between the first connecting part and the mounting plate 112.

[0055] Among them, such as Figure 1 , Figure 2 As shown, the mounting plate 112 is provided with limiting holes 113, which are axially continuous. Multiple limiting holes 113 are provided, and they are equidistantly distributed along the same circumference. Figure 3 As shown, the limiting hole 113 is threaded and is used to install bolts or screws and other connecting parts so that the bearing assembly 4 can be connected to the mounting plate 112, making it convenient for workers to disassemble and assemble.

[0056] In this embodiment, as Figure 2 As shown, the axial thickness of the mounting plate 112 is greater than the axial thickness of the first connecting plate 111. The upper end face of the mounting plate 112 protrudes from the upper end face of the first connecting plate 111, and the lower end face of the mounting plate 112 protrudes from the lower end face of the first connecting plate 111. The mounting plate 112 is made thicker, thereby increasing the structural strength of the mounting plate 112. In addition, as shown... Figure 3 As shown, this allows the mounting plate 112 to be connected independently to the bearing assembly 4, reducing interference between the bearing assembly 4 and the first connecting plate 111. The first mounting is mounted on the mounting plate 112.

[0057] like Figure 1 , Figure 2As shown, the connecting vertical plate 13 is a plate-shaped structure. The horizontal width of the connecting vertical plate 13 is smaller than the horizontal width of the first connecting plate 111, and the horizontal width of the connecting vertical plate 13 is larger than the inner diameter of the first mounting opening 114 of the mounting plate 112. The connecting vertical plate 13 is arranged axially and is perpendicularly connected to the first connecting plate 111. The connecting vertical plate 13 is connected to the first connecting plate 111 of the first connecting assembly 11. A bending part is provided at the connection between the first connecting plate 111 and the connecting vertical plate 13, that is, the angle at the connection between the first connecting plate 111 and the connecting vertical plate 13 is bent. This can reduce the stress concentration between the first connecting plate 111 and the connecting vertical plate 13, so that the stress can be evenly distributed, thereby increasing the structural strength of the first connecting plate 111 and the connecting vertical plate 13.

[0058] In one optional embodiment of this application, the connecting vertical plate 13 and the first connecting plate 111 are separate structures, and the connecting vertical plate 13 and the first connecting plate 111 are welded together to ensure the connection stability between the first connecting plate 111 and the connecting vertical plate 13.

[0059] In another optional embodiment of this application, the connecting vertical plate 13 is integrally formed with the first connecting plate 111 to enhance the structural strength of the connecting seat 1.

[0060] Based on any of the above embodiments, the second connecting component 12 will be further described; such as Figure 1 , Figure 2 As shown, the second connecting assembly 12 includes a second connecting plate 121 and a reinforcing plate 122. The second connecting plate 121 is a plate-shaped structure and is arranged parallel to the first connecting plate 111. The reinforcing plate 122 is a plate-shaped structure and is arranged parallel to the connecting vertical plate 13. The reinforcing plate 122 is vertically connected to the upper end of the second connecting plate 121 and is located at the end of the second connecting plate 121 near the connecting vertical plate 13. The reinforcing plate 122 extends in the axial direction and at least partially overlaps with the connecting vertical plate 13. The reinforcing plate 122 is in contact with the connecting vertical plate 13. The reinforcing plate 122 is welded to the connecting vertical plate 13 to ensure the connection strength between the connecting vertical plate 13 and the reinforcing plate 122.

[0061] In this embodiment, as Figure 1 , Figure 2 As shown, a bending part is provided at the connection between the reinforcing plate 122 and the second connecting plate 121, that is, the angle at the connection between the second connecting plate 121 and the reinforcing plate 122 is bent. This can reduce the stress concentration between the second connecting plate 121 and the reinforcing plate 122, so that the stress can be evenly distributed, thereby increasing the structural strength of the second connecting plate 121 and the reinforcing plate 122.

[0062] In an optional embodiment of this application, the reinforcing plate 122 and the second connecting plate 121 are separate structures, and the reinforcing plate 122 and the second connecting plate 121 are welded together to ensure the connection stability between the second connecting plate 121 and the reinforcing plate 122.

[0063] In another optional embodiment of this application, the reinforcing plate 122 is integrally formed with the second connecting plate 121 to enhance the structural strength of the connecting seat 1.

[0064] Furthermore, such as Figure 1 , Figure 2 As shown, the second mounting port 126 is provided on the second connecting plate 121; the second connecting plate 121 is provided with mounting holes 125, which penetrate the second connecting plate 121 axially, and multiple mounting holes 125 are distributed at equal intervals along the same circumference on the outside of the second mounting port 126; threads can be provided in the mounting holes 125, such as... Figure 3 As shown, the mounting hole 125 provides mounting space for bolts or screws, so that the steering pump 3 can be connected to the second connecting plate 121, making it convenient for workers to disassemble and assemble.

[0065] Furthermore, such as Figures 1 to 3 As shown, the second connecting plate 121 has a limiting groove 124 on the side facing the steering pump 3. The limiting groove 124 is located at the bottom of the second connecting plate 121 and is recessed towards the first connecting plate 111. The limiting groove 124 has a circular structure and its diameter is larger than the inner diameter of the second mounting port 126. The top of the steering pump 3 is tightly fitted to the bottom of the second connecting plate 121 so that the steering pump 3 is at least partially located in the limiting groove 124. The limiting groove 124 is used to limit the steering pump 3 so that the steering pump 3 will not easily deviate, ensuring the connection stability between the steering pump 3 and the second connecting plate 121, so that the steering pump 3 can be vertically installed on the connecting seat 1, ensuring the transmission stability of the steering pump 3 to the rotating shaft 5, thereby ensuring the stable operation of the steering device.

[0066] The limiting groove 124 is made by milling.

[0067] Furthermore, such as Figures 1 to 3As shown, the second connecting assembly 12 also includes a frame connecting plate 123. The frame connecting plate 123 is arranged axially and has a plate-like structure. The width direction of the frame connecting plate 123 is perpendicular to the width direction of the connecting vertical plate 13. The frame connecting plate 123 is vertically connected to the side of the second connecting plate 121 away from the first connecting plate 111. That is, the frame connecting plate 123 is located at the bottom of the second connecting plate 121 and at the end away from the connecting vertical plate 13. In this embodiment, the frame connecting plate 123 is provided with a plurality of connecting holes. The connecting holes penetrate the frame connecting plate 123 horizontally to facilitate the connection between the frame connecting plate 123 and the driving area of ​​the underground shovel loader. This can increase the connection strength between the connecting seat 1 and the driving area of ​​the underground shovel loader and ensure the connection stability of the steering device.

[0068] Second aspect

[0069] This application provides a steering device for an underground loader, including a connecting seat 1 in any embodiment provided in the first aspect.

[0070] Specifically, such as Figure 3 As shown, the steering device also includes a bearing assembly 4 and a rotating shaft 5. The rotating shaft 5 passes through the connecting seat 1, and its two ends are connected to the steering pump 3 and the steering wheel 2, respectively. The bearing assembly 4 is sleeved on the rotating shaft 5 and is connected to the first connecting component 11 of the connecting seat 1, while the second connecting component 12 is connected to the steering pump 3. This design eliminates the direct connection between the bearing assembly 4 and the steering pump 3. When maintaining the bearing assembly 4, it is not necessary to disconnect the connecting seat 1 from the steering pump 3; the bearing assembly 4 can be directly removed from the first connecting component 11 for maintenance. This greatly simplifies the maintenance procedure of the steering device and makes it easier for staff to repair it.
