Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a slewing support assembly and a grader. Background Technology

[0002] In northern winters, rain, snow, freezing rain, or fog can easily lead to snow accumulation or icing. Frozen snow, uneven ruts, melted snow, or other road water can form hard ice layers in the cold season. Icy roads greatly reduce the friction between vehicle wheels, pedestrian shoes, and the road surface, making it easy to slip and causing vehicle collisions, pedestrian slips, and other safety accidents.

[0003] Current road snow and ice removal equipment combines with graders. Existing snow and ice removal equipment primarily uses blades to remove ice and snow from the road surface for rapid clearing. However, for roads already covered with hard ice, blades alone are insufficient. Therefore, for these surfaces, an ice-breaking mechanism is needed to break the ice first, followed by blade removal. However, most existing graders lack attachment changing capabilities and are generally only equipped with blades, not ice-breaking mechanisms, which limits the clearing operations on special icy and snowy roads. Utility Model Content

[0042] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0043] This utility model provides a slewing support assembly. (Refer to...) Figures 1 to 5 As shown, the slewing support assembly includes a traction frame 1, a slewing support base 2, and a transition assembly. The slewing support base 2 includes a slewing base body 21 and a connecting frame 22. The slewing base body 21 is rotatably connected to the traction frame 1, and the connecting frame 22 is located on opposite sides of the slewing base body 21. The transition assembly includes a first transition block 31 and a second transition block 32. The first transition block 31 is used to install the ice-breaking mechanism 6, and the second transition block 32 is used to install the shovel blade 7. Either the first transition block 31 or the second transition block 32 can be selectively fixedly connected to the connecting frame 22.

[0044] In this embodiment, the slewing support assembly is provided with a first adapter block 31 and a second adapter block 32. Either the first adapter block 31 or the second adapter block 32 can be selectively connected to the connecting frame 22 of the slewing support base 2. When the connecting frame 22 is connected to the first adapter block 31, the ice-breaking mechanism 6 can be connected via the first adapter block 31; when the connecting frame 22 is connected to the second adapter block 32, the blade 7 can be connected via the second adapter block 32. The blade 7 is suitable for clearing roads with a lot of snow but relatively little ice, while the ice-breaking mechanism 6 is used to break and clear hard ice surfaces on the road. This structure allows for the replacement of ice and snow clearing attachments according to actual working needs, ensuring reliability and applicability under different ice and snow clearing conditions.

[0045] In this embodiment, the connecting frame 22 has a mounting hole 221, the first adapter block 31 has a first connecting hole 3101, and the second adapter block 32 has a second connecting hole 321. A first fixing member 33 passes through the first connecting hole 3101 and the mounting hole 221 for fixed connection, thereby fixing the connecting frame 22 and the first adapter block 31. A second fixing member 34 passes through the second connecting hole 321 and the mounting hole 221 for fixed connection, thereby fixing the connecting frame 22 and the second adapter block 32. In this embodiment, the first fixing member 33 enables a detachable connection between the first adapter block 31 and the connecting frame 22, and the second fixing member 34 enables a detachable connection between the second adapter block 32 and the connecting frame 22.

[0046] For example, the first fixing member 33 includes a first bolt, the second fixing member 34 includes a second bolt, and the mounting hole 221 is a threaded hole. The first bolt passes through the first connecting hole 3101 and the mounting hole 221 for threaded connection; the second bolt passes through the second connecting hole 321 and is threadedly connected to the mounting hole 221. The first adapter block 31 and the connecting frame 22 are reliably fastened together by the first bolt, which facilitates disassembly and ensures a reliable and stable structure; the second adapter block 32 and the connecting frame 22 are reliably fastened together by the second bolt, which also facilitates disassembly and ensures a reliable and stable structure.

[0047] For example, the number of the first transition block 31 and the second transition block 32 can be set to one or more, without further limitation here.

[0048] In this embodiment, the first adapter block 31 includes a first adapter portion 311 and a first mounting portion 312 connected to each other. The first adapter portion 311 is attached to the connecting frame 22, and a first connecting hole 3101 is formed in the first adapter portion 311. The first mounting portion 312 is used to attach to and connect to the ice-breaking mechanism 6. Specifically, the first adapter portion 311 is attached to the connecting frame 22, and the first mounting portion 312 is attached to the ice-breaking structure to realize the installation and positioning between the rotary support 2, the first adapter block 31, and the ice-breaking mechanism 6.

[0049] For example, the first adapter portion 311 and the first mounting portion 312 are arranged in an L-shape, and a first reinforcing rib 313 connects the first adapter portion 311 and the first mounting portion 312. The provision of the first reinforcing rib 313 can improve the connection strength between the first adapter portion 311 and the first mounting portion 312, and prevent deformation or breakage between the first adapter portion 311 and the first mounting portion 312.

[0050] In this embodiment, the first adapter 311, the first mounting part 312, and the first reinforcing rib 313 are integrally formed. This arrangement facilitates manufacturing and avoids the process of separate assembly of the first adapter 311, the first mounting part 312, and the first reinforcing rib 313.

[0051] In this embodiment, the first adapter 311 has a first pin hole 3102, and the connecting frame 22 has a second pin hole 222. A first anti-rotation pin 35 passes through the first pin hole 3102 and the second pin hole 222 to prevent rotation between the first adapter 311 and the connecting frame 22. Specifically, when the connecting frame 22 and the first adapter 311 are fixed together by only one first screw, the first anti-rotation pin 35 passes through the first pin hole 3102 and the second pin hole 222. With the fixing effect of the first bolt, it can reliably prevent rotation of the first adapter block 31 and avoid deflection between the rotary support 2 and the first adapter block 31.

[0052] In this embodiment, the rotary support 21 has a third pin hole 211, and the traction frame 1 has a fourth pin hole 11. The third pin hole 211 and the fourth pin hole 11 can accommodate a second anti-rotation pin to prevent rotation between the rotary support 21 and the traction frame 1. Optionally, when the ice-breaking mechanism 6 is installed on the rotary support 2, the second anti-rotation pin needs to be installed, specifically by passing through the third pin hole 211 and the fourth pin hole 11. This prevents rotation between the rotary support 2 and the traction frame 1, ensuring reliable and stable operation of the ice-breaking mechanism 6. When the blade 7 is installed on the rotary support 2, the second anti-rotation pin needs to be removed, specifically by disengaging it from the third pin hole 211 and the fourth pin hole 11. This releases the anti-rotation mechanism between the rotary support 2 and the traction frame 1, allowing the rotary support 2 to rotate again.

[0053] In this embodiment, a second reinforcing rib 23 is provided between the rotary support body 21 and the connecting frame 22. The provision of the second reinforcing rib 23 can further improve the connection strength between the rotary support body 21 and the connecting frame 22, prevent deformation or breakage between the rotary support body 21 and the connecting frame 22, and ensure the overall strength reliability of the rotary support 2.

[0054] This embodiment also provides a grader. The grader includes the aforementioned slewing support assembly, and further includes a main boom 4, a movable mechanism 5, an ice-breaking mechanism 6, and a blade 7. The first end of the traction frame 1 is hinged to the main boom 4. The movable mechanism 5 is mounted on the main boom 4 and connected to the second end of the traction frame 1. The movable mechanism 5 drives the traction frame 1 to swing around a first direction and a second direction. The slewing support 2 can rotate relative to the traction frame 1 around a third direction. The ice-breaking mechanism 6 is connected to the connecting frame 22 via a first adapter block 31, and the blade 7 is connected to the connecting frame 22 via a second adapter block 32.

[0055] In this embodiment, the first direction, the second direction, and the third direction are orthogonally arranged in pairs.

[0056] In this embodiment, the moving mechanism 5 includes a first drive cylinder 51 and a second drive cylinder 52. The first drive cylinders 51 are arranged in pairs on opposite sides of the main arm 4. The cylinder body of the first drive cylinder 51 is hinged to the main arm 4, and the cylinder rod is hinged to the traction frame 1. The extension and retraction of the cylinder rod of the first drive cylinder 51 relative to the cylinder body can drive the traction frame 1 to swing around a first direction. The second drive cylinder 52 is inclined between the main arm 4 and the traction frame 1. The cylinder body of the second drive cylinder 52 is hinged to the main arm 4, and the cylinder rod is hinged to the traction frame 1. The extension and retraction of the cylinder rod of the second drive cylinder 52 relative to the cylinder body can drive the traction frame 1 to swing around a second direction. Specifically, the cylinder rods of the first drive cylinders 51 on both sides of the main boom 4 extend outward relative to the cylinder body, causing the second end of the traction frame 1 to swing away from the main boom 4, i.e., the second end of the traction frame 1 approaches the ground (ice surface); simultaneously, the cylinder rods of the first drive cylinders 51 on both sides of the main boom 4 retract outward relative to the cylinder body, causing the second end of the traction frame 1 to swing towards the main boom 4, i.e., the second end of the traction frame 1 moves away from the ground (ice surface). Specifically, the cylinder rod of the second drive cylinder 52 extends outward relative to the cylinder body, causing the traction frame 1 to tilt up on the first side and drop on the second side along the first direction; retracting the cylinder rod of the second drive cylinder 52 relative to the cylinder body, causing the traction frame 1 to drop on the first side and tilt up on the second side along the first direction.

[0057] Specifically, in this embodiment, the cylinder rod of the first drive cylinder 51 is provided with a first ball joint, and the traction frame 1 is provided with a first ball socket, with the first ball joint movably disposed within the first ball socket. Specifically, the cooperation between the first ball joint and the first ball socket enables multi-directional hinged connection between the first drive cylinder 51 and the traction frame 1. The cylinder rod of the second drive cylinder 52 is provided with a second ball joint, and the traction frame 1 is provided with a second ball socket, with the second ball joint movably disposed within the second ball socket. Specifically, the cooperation between the second ball joint and the second ball socket enables multi-directional hinged connection between the second drive cylinder 52 and the traction frame 1. The first end of the traction frame 1 is provided with a third ball joint, and the main arm 4 is provided with a third ball socket, with the third ball joint movably disposed within the third ball socket. Specifically, the cooperation between the third ball joint and the third ball socket enables multi-directional hinged connection between the main arm 4 and the traction frame 1, ensuring flexible movement without jamming.

[0058] For example, the first hinge portion includes a fourth ball socket, and the cylinder body of the first drive cylinder 51 is correspondingly provided with a fourth ball head, which is movably disposed within the fourth ball socket. The second hinge portion includes a fifth ball socket, and the cylinder body of the second drive cylinder 52 is correspondingly provided with a fifth ball head, which is movably disposed within the fifth ball socket.

[0059] In this embodiment, the ice-breaking mechanism 6 includes a frame 61, a milling roller 62 mounted on the frame 61, and a driving component. During use, the traction frame 1 is controlled by the movable mechanism 5 to swing relative to the main arm 4 around a first direction and a second direction, thereby adjusting the position of the milling ice-breaking mechanism 6 so that the milling roller 62 contacts the ice surface on the ground. The driving component operates, driving the milling roller 62 to rotate around the frame 61, thereby breaking the ice on the contacted ice surface.

[0060] Specifically, the milling roller 62 includes a roller body 621 and multiple ice-breaking blades 622. The roller body 621 is rotatably connected to the frame 61. A drive unit drives the roller body 621 to rotate. The multiple ice-breaking blades 622 are distributed circumferentially along the roller body 621, and each ice-breaking blade 622 extends axially along the roller body 621. Specifically, during ice-breaking operations, the milling roller body 621, compared to an ice-breaking shovel structure, effectively reduces the contact area between itself and the ice surface, thus reducing friction. Furthermore, during the rolling of the milling roller 62, the multiple ice-breaking blades 622 can penetrate into the ice surface, and together with the roller body 621, the rolling pressure on the ice surface accelerates the breaking of the ice, quickly breaking a whole block of ice into multiple small pieces that separate from each other.

[0061] Specifically, the ice-breaking blade 622 has multiple serrated structures at its tip, which improves the effectiveness and reliability of the ice-breaking blade 622 in penetrating the ice surface.

[0062] Furthermore, the driving component includes a hydraulic motor 63 mounted on the frame 61, which is connected to the milling roller 62 via a transmission assembly. Specifically, the transmission assembly can be configured as a gear transmission assembly to achieve the transmission connection between the hydraulic motor 63 and the milling roller 62.

[0063] Specifically, a hydraulic mechanism 64 is also provided on the frame 61. The hydraulic mechanism 64 supplies hydraulic oil to the hydraulic motor 63, which drives the hydraulic motor 63 to work and output power to drive the milling roller 62 to rotate.

[0064] In addition to being configured as a hydraulic motor 63, the driving component can also be configured as a drive motor, etc.

[0065] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
