Description

Technical Field

[0001] This utility model relates to a rotary tilting connector, belonging to the field of engineering machinery technology. Background Technology

[0002] Currently, excavators are widely used. Attachments such as buckets, grabs, and breakers can be installed on excavators via quick-change connectors according to production and operation needs. This not only expands the scope of excavator use, but also makes it quick and convenient to install and disassemble various attachments, thus improving work efficiency.

[0003] The connector is used to attach attachments to the excavator's boom. It is limited to a quick-change function, enabling the attachment to be installed and positioned on the excavator's boom. It cannot change the excavator's single working direction. The working direction of the attachment is adjusted entirely by adjusting the excavator's boom. This operation is fine in places with large working spaces, but when the working range is limited, adjusting the working direction and position of the attachment by adjusting the excavator is no longer applicable. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a rotary tilt connector.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A rotary tilt connector includes a connecting part connected to an excavator and a quick-change part connected to an attachment, and also includes a rotary mechanism and a swing mechanism. The rotary mechanism and the swing mechanism are disposed between the connecting part and the quick-change part. The rotary mechanism is used to drive the quick-change part to perform a rotary action, and the swing mechanism is used to drive the quick-change part to perform a swing action.

[0006] The swing mechanism includes a first swing component and a second swing component. The rotary mechanism is located between the first swing component and the second swing component. The connecting component includes a connecting frame. The quick-change component includes a quick-change frame. The housings of the first swing component and the second swing component are connected to the connecting frame. The driving ends of the first swing component and the second swing component are respectively connected to the rotary housing of the rotary mechanism. The driving end of the rotary mechanism is connected to the quick-change component.

[0007] The beneficial effects of this utility model are as follows: The swing mechanism and the rotary mechanism of the connector are located between the connecting part and the quick-change part, and the rotary mechanism is located between the first swing part and the second swing part. Compared with the connector with swing cylinders on both sides, the swing cylinders have a long driving stroke, which makes the connector very high. Also, because they are on both sides of the connector, the thickness of the connector is also very thick. With this connector, not only is the height greatly reduced, but the thickness is also thinned. The structure of the connector is more compact and the volume is smaller, so that the attachment can not only rotate, but also swing to both sides and lock at a certain angle. The working direction and working position of the attachment can be adjusted using this connector, and it can be used to work in narrow and limited spaces.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the connecting component also includes a first connecting shaft and a second connecting shaft for connecting with the excavator, and the connecting frame includes a first connecting support plate and a second connecting support plate, with the first connecting shaft and the second connecting shaft respectively disposed between the first connecting support plate and the second connecting support plate.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the first connecting shaft and the second connecting shaft can be stably connected to the excavator, ensuring stability and safety during operation. The first connecting support plate and the second connecting support plate play the role of supporting and fixing the connecting shaft, thereby enhancing the overall strength of the connecting components.

[0011] Furthermore, the quick-change frame includes a connecting plate connected to the drive end of the rotary mechanism, and the quick-change component also includes a fixed latching part, a movable latching part, and a hydraulic cylinder for adjusting the movable latching part. The fixed latching part is fixedly mounted on the quick-change frame, and the movable latching part is connected to the quick-change frame via a hinge pin. One end of the hydraulic cylinder is hinged to the quick-change frame, and the other end is connected to the movable latching part.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the rotary mechanism realizes the rotary drive of the quick-change component through the connecting plate. The movable locking part moves relative to the fixed locking part under the drive of the hydraulic cylinder, thereby realizing the function of quick change of attachment. The movable locking part is installed on the quick-change frame through the hinge pin. The hydraulic cylinder serves as a power source, and its extension and retraction movement drives the movable locking part to rotate around the hinge pin as the fulcrum, thereby adjusting the distance between the movable locking part and the fixed locking part, and thus realizing the quick locking and release of the attachment.

[0013] Furthermore, the rotary mechanism employs a worm gear reducer.

[0014] The advantages of adopting the above-mentioned further solutions are that the worm gear reducer has a high transmission ratio and a large torque output, which can meet the requirements for stable and reliable rotary drive of quick-change components. The worm gear reducer has a compact structure and relatively small size, making it suitable for installation inside rotary tilting connectors without occupying too much space, thus making the connector more compact and lightweight.

[0015] Furthermore, the first swing component and the second swing component are respectively equipped with swing hydraulic motors.

[0016] The beneficial effects of adopting the above-mentioned further solution are that the swing hydraulic motor has a compact structure, large output torque, and smooth rotation. The drive end of the swing hydraulic motor is connected to the rotary housing of the rotary mechanism, which can realize the control of the connector in the tilting swing direction and meet the requirements of the connector to work stably under various working conditions.

[0017] Furthermore, the rotation center line of the rotary mechanism is perpendicular to the swing axis of the swing mechanism.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the connector can maintain good stability and balance when tilted and rotated, the rotary mechanism can rotate stably on the rotary plane, and the swing mechanism can swing smoothly on the swing axis. The two work together to meet the needs of the connector for angle adjustment and position positioning under complex working conditions.

[0019] Furthermore, the rotation center line of the rotary mechanism intersects with the swing axis of the swing mechanism.

[0020] The advantages of adopting the above-mentioned further solution are that the perpendicular intersection between the rotation center line and the swing axis allows the connector to maintain better synchronization and coordination when rotating and tilting. The swing mechanism and the swing tilt of the quick-change component can be driven by a small swing driving force. In addition, it also helps to reduce the overall size of the connector, making it more compact and applicable to a wider range of applications.

[0021] Furthermore, the connecting frame is provided with a first lifting plate and a second lifting plate, the first swing component is disposed on the first lifting plate, and the second swing component is disposed on the second lifting plate.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the first and second lifting plates enable the first and second swing components to be stably installed on the connecting frame, which not only makes the structure compact and easy to install and maintain, but also meets the requirements of stability and reliability of the swing mechanism during operation.

[0023] Furthermore, the first swing component is provided with a first flange for connecting to the first lifting plate, and the second swing component is provided with a second flange for connecting to the second lifting plate.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the first flange and the second flange, as connecting parts, are connected to the first lifting plate and the second lifting plate respectively. The connection is stable and reliable, and can withstand a large load, ensuring that the connector will not loosen or fall off during tilting and swinging.

[0025] Furthermore, both the first and second lifting plates are provided with swing mounting holes through which the first and second swing components pass.

[0026] The beneficial effect of adopting the above-mentioned further solution is that the swing component can be inserted into the swing mounting hole and then connected to the lifting plate through its flange, thereby achieving a stable connection between the swing mechanism and the connecting frame. This improves the overall stability and reliability of the connector.

[0027] Furthermore, the housing of the rotary mechanism is provided with a first connecting seat and a second connecting seat on both sides, the driving end of the first swing component is connected to the first connecting seat, and the driving end of the second swing component is connected to the second connecting seat.

[0028] The beneficial effect of adopting the above-mentioned further solution is that the driving end of the swing component is connected to the rotary mechanism through the connecting seat, which ensures that the connection between the driving end of the swing component and the housing of the rotary mechanism is stable, improves the assembly efficiency of the swing component and the rotary mechanism, ensures that the swing component can stably transmit power during the driving process, and makes the connector have higher stability and reliability during tilting and rotation.

Detailed Implementation

[0034] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0035] like Figures 1-4 As shown, a rotary tilt connector includes a connecting part 1 connected to an excavator and a quick-change part 5 connected to an attachment. It also includes a slewing mechanism 2 and a swinging mechanism. The slewing mechanism 2 and the swinging mechanism are disposed between the connecting part 1 and the quick-change part 5. The slewing mechanism 2 is used to drive the quick-change part 5 to rotate, and the swinging mechanism is used to drive the quick-change part 5 to swing.

[0036] The swing mechanism includes a first swing component 3 and a second swing component 4. The rotary mechanism 2 is located between the first swing component 3 and the second swing component 4. The connecting component 1 includes a connecting frame. The quick-change component 5 includes a quick-change frame 501. The housings of the first swing component 3 and the second swing component 4 are connected to the connecting frame. The driving ends of the first swing component 3 and the second swing component 4 are respectively connected to the two sides of the rotary housing of the rotary mechanism 2. The driving end of the rotary mechanism 2 is connected to the quick-change component 5.

[0037] The connecting component 1 further includes a first connecting shaft 101 and a second connecting shaft 102 for connection with an excavator. The connecting frame includes a first connecting support plate 103 and a second connecting support plate 104, with the first connecting shaft 101 and the second connecting shaft 102 respectively disposed between the first connecting support plate 103 and the second connecting support plate 104. The first connecting shaft 101 and the second connecting shaft 102 can be stably connected to the excavator, ensuring stability and safety during operation. The first connecting support plate 103 and the second connecting support plate 104 serve to support and fix the connecting shafts, enhancing the overall strength of the connecting component 1.

[0038] The quick-change frame 501 includes a connecting plate 502 connected to the drive end of the rotary mechanism 2. The quick-change component 5 also includes a fixed latching part 503, a movable latching part 504, and a hydraulic cylinder for adjusting the movable latching part 504. The fixed latching part 503 is fixedly mounted on the quick-change frame 501. The movable latching part 504 is connected to the quick-change frame 501 via a hinge pin 506. One end of the hydraulic cylinder is hinged to the quick-change frame 501, and the other end is connected to the movable latching part 504. The rotary mechanism 2 drives the quick-change component 5 to rotate via the connecting plate 502. The movable latching part 504 moves relative to the fixed latching part 503 under the drive of the hydraulic cylinder, thereby realizing the function of quick tool changing. The movable latching part 504 is mounted on the quick-change frame 501 via the hinge pin 506. The hydraulic cylinder serves as the power source, and its extension and retraction motion drives the movable latching part 504 to rotate around the hinge pin 506 as the fulcrum. This allows adjustment of the distance between the movable latching part 504 and the fixed latching part 503, thereby realizing quick locking and releasing of the tool.

[0039] The rotary mechanism 2 employs a worm gear reducer. The worm gear reducer has a high transmission ratio and large torque output, enabling stable and reliable rotary drive of the quick-change component 5. The worm gear reducer has a compact structure and relatively small size, making it suitable for installation inside the rotary tilting connector without occupying excessive space, thus making the connector more compact and lightweight.

[0040] The worm gear reducer includes a rotary housing, a rotary disk, a rotary hydraulic motor, a worm, and a worm wheel meshing with the worm. The first connecting seat 8 and the second connecting seat are respectively located on both sides of the rotary housing. The quick-change component 5 is connected to the rotary disk via the connecting plate 502. The rotary hydraulic motor drives the worm to rotate, and the worm is rotatably mounted on the rotary housing. The worm wheel is connected to the rotary disk, and the rotary disk is rotatably mounted on the rotary housing. When the rotary hydraulic motor rotates, it drives the worm to rotate, causing the worm wheel meshing with the worm to rotate, thereby rotating the rotary disk. The quick-change component 5 rotates with the rotary disk, thus enabling the attachment to rotate.

[0041] The first swing component 3 and the second swing component 4 are respectively equipped with swing hydraulic motors. The swing hydraulic motor has a compact structure, large output torque, and smooth rotation. The drive end of the swing hydraulic motor is connected to the rotary housing of the rotary mechanism 2, which can realize the control of the connector in the tilting swing direction and meet the requirements of stable operation of the connector under various working conditions.

[0042] The rotation center line of the rotary mechanism 2 is perpendicular to the swing axis of the swing mechanism. The connector can maintain good stability and balance when tilted and rotated. The rotary mechanism can rotate stably on the rotation plane, while the swing mechanism swings smoothly on the swing axis. The two work together to meet the requirements of angle adjustment and position positioning of the connector under complex working conditions.

[0043] The rotation center line of the rotary mechanism 2 intersects the swing axis of the swing mechanism. The perpendicular intersection between the rotation center line and the swing axis allows the connector to maintain better synchronization and coordination when rotating and tilting. It can drive the rotation mechanism and the swing tilt of the quick-change component with a small swing driving force. In addition, it also helps to reduce the overall size of the connector, making it more compact and applicable to a wider range of situations.

[0044] The connecting frame is provided with a first lifting plate 6 and a second lifting plate 7. The first swing component 3 is disposed on the first lifting plate 6, and the second swing component 4 is disposed on the second lifting plate 7. The first lifting plate 6 and the second lifting plate 7 enable the first swing component 3 and the second swing component 4 to be stably installed on the connecting frame. This not only results in a compact structure that is easy to install and maintain, but also meets the requirements of stability and reliability of the swing mechanism during operation.

[0045] The first swing component 3 is provided with a first flange for connecting to the first lifting plate 6, and the second swing component 4 is provided with a second flange for connecting to the second lifting plate 7. The first flange and the second flange serve as connecting parts, connecting to the first lifting plate 6 and the second lifting plate 7 respectively. The connection is stable and reliable, capable of withstanding large loads, and ensuring that the connector will not loosen or fall off during tilting and swinging.

[0046] Both the first lifting plate 6 and the second lifting plate 7 are provided with swing mounting holes through which the first swing component 3 and the second swing component 4 pass. The swing components can be inserted into the swing mounting holes and then connected to the lifting plate through their flanges, achieving a stable connection between the swing mechanism and the connecting frame. This improves the overall stability and reliability of the connector.

[0047] The housing of the rotary mechanism 2 is provided with a first connecting seat 8 and a second connecting seat 9 on both sides. The driving end of the first swing component 3 is connected to the first connecting seat 8, and the driving end of the second swing component 4 is connected to the second connecting seat 9. The driving end of the swing component is connected to the rotary mechanism 2 through the connecting seat, ensuring a stable connection between the driving end of the swing component and the housing of the rotary mechanism 2, improving the assembly efficiency of the swing component and the rotary mechanism 2, and ensuring that the swing component can stably transmit power during the driving process, so that the connector has higher stability and reliability during tilting and rotation.

[0048] The hydraulic cylinder 505 functions to allow the movable locking part 504 to rotate around the hinge pin 506. The movable locking part 504 and the fixed locking part 503 can connect to the shaft on the attachment. The rotary mechanism 2 and the swing mechanism enable the connector to drive the attachment connected to the quick-change component 5 to rotate 360 ​​degrees around itself and drive the attachment to tilt and swing left and right, enabling the attachment to work in all directions and at multiple angles. The swing mechanism and rotary mechanism 2 of the connector are located between the connecting component 1 and the quick-change component 5, and the rotary mechanism 2 is located between the first swing component 3 and the second swing component 4. This makes the connector not only significantly reduced in height but also thinner in thickness, resulting in a more compact structure and smaller size. It enables the adjustment of the working direction and position of the attachment, allowing it to work in narrow and limited spaces.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
