Abstract
Description
Technical Field
[0001] The utility model relates to a luffing mechanism, in particular to a luffing mechanism for ultra-low space. Background Art
[0002] With the rapid development of technology, intelligent devices are increasingly widely used in all walks of life, and the complexity and diversity of their working environments have also increased accordingly. Especially in some extreme or special working conditions, such as working in ultra-low and ultra-narrow spaces, traditional equipment often struggles to cope, which not only limits work efficiency but also increases operation difficulty and safety risks. Therefore, it is particularly important to develop a new luffing mechanism that can adapt to and optimize such complex working conditions.
[0003] In the prior art, as a key component to improve the flexibility and adaptability of equipment, the luffing mechanism is widely used in various construction machinery and special vehicles. However, when faced with the need to pass through ultra-low and ultra-narrow spaces, traditional luffing mechanisms often face problems such as being too large in size and difficult to retract small enough to pass through the height-limiting layer. In addition, when it is necessary to extend to an extremely high size during the working state to meet the working condition requirements, how to ensure the structural stability and extension efficiency of the mechanism is also a technical challenge.
[0004] To solve the above problems, the traditional approach usually uses a common oil cylinder mechanism to achieve luffing motion. However, in some extreme working conditions, these mechanisms often struggle to balance a compact retracted state and efficient extension ability. At the same time, in the slewing function state, the common oil cylinder mechanism may also interfere with the mounting surface of the luffing oil cylinder, further restricting its application range. Summary of the Utility Model
[0005] To solve the above technical problems, the utility model provides a luffing mechanism for ultra-low space. The luffing mechanism combines a slewing mechanism and is optimized for the dimensions of spatial luffing, enabling luffing and slewing actions with maximum extension and minimum retraction to meet the passing requirements of ultra-low and ultra-narrow spaces.
[0006] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0007] A luffing mechanism for ultra-low space, including a slewing mechanism. A first oil cylinder is arranged inside the slewing mechanism. Both the slewing mechanism and the first oil cylinder are installed on a workbench. A first fixed seat is installed on the slewing mechanism. The first fixed seat is rotatably connected to a second fixed seat. A telescopic arm is fixedly connected inside the second fixed seat. The other end of the telescopic arm is connected to a hanging basket. The output end of the first oil cylinder is connected to a first connecting shaft, and the first connecting shaft is rotatably connected to the second fixed seat.
[0008] In an embodiment of the present utility model, the first fixing seat has a triangular structure, and an accommodation space for accommodating part of the second fixing seat and the telescopic arm is provided inside it.
[0009] In an embodiment of the present utility model, a second connecting shaft is provided at the upper end of the first fixing seat with a triangular structure. The second connecting shaft passes through the second fixing seat and the first fixing seat, and the first fixing seat is rotatably connected to the second fixing seat through the second connecting shaft.
[0010] In an embodiment of the present utility model, a third fixing seat is fixedly connected to one end of the telescopic arm away from the second fixing seat.
[0011] In an embodiment of the present utility model, a second oil cylinder is installed inside the third fixing seat. The output end of the second oil cylinder is connected to a third connecting shaft. The third connecting shaft is installed in the connecting seat, and the third connecting shaft is rotatably connected to the connecting seat.
[0012] In an embodiment of the present utility model, the connecting seat is fixedly connected to a fourth connecting shaft. The fourth connecting shaft is installed in the third fixing seat, and the fourth connecting shaft is rotatably connected to the third fixing seat.
[0013] In an embodiment of the present utility model, the fourth connecting shaft is fixedly connected to a fourth fixing seat.
[0014] In an embodiment of the present utility model, the fourth fixing seat is connected to a rotary oil cylinder. The rotary oil cylinder is connected to a fifth fixing seat, and the rotary oil cylinder is used to drive the fifth fixing seat to rotate.
[0015] In an embodiment of the present utility model, the fifth fixing seat is fixedly connected to the hanging basket.
[0016] In an embodiment of the present utility model, the slewing mechanism is a hydraulic slewing bearing.
[0017] The present utility model has the following beneficial effects:
[0018] The luffing mechanism for ultra-low space provided by the present utility model drives the first fixed seat and various structures above it to rotate through a slewing mechanism to achieve the slewing function of the equipment. When the first oil cylinder is in the retracted state, the telescopic arm rotates to the horizontal state, which can greatly shorten the distance between the telescopic arm and the slewing mechanism, thereby reducing the height of the luffing mechanism, so that the luffing mechanism can be suitable for ultra-low space and enable the luffing mechanism to pass through the height-limiting layer in the ultra-low retracted state. When the first oil cylinder is in the extended state, the telescopic arm can extend to a super-high dimension for working conditions, maximizing the use of space. Thus, the luffing mechanism combines with the slewing mechanism and cooperates with the size optimization of the space luffing to achieve luffing and slewing actions with maximum extension and minimum retraction to meet the passing requirements of ultra-low and ultra-narrow spaces. Moreover, the luffing mechanism not only improves the flexibility and adaptability of the equipment but also ensures the efficient coordination of the luffing and slewing actions without sacrificing the structural strength and stability. In addition, through the reasonable layout among the above structures, the luffing mechanism is compact in internal installation and more beautiful and generous in external form, meeting both the functional requirements and enhancing the user experience. In summary, the luffing mechanism can take into account the passing performance in ultra-low and ultra-narrow spaces and the efficient working ability under working conditions, which is of great significance for improving the equipment performance, reducing the operation difficulty, and enhancing the safety.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0029] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above the top of", and "on the top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the first feature is at a higher horizontal height than the second feature. The first feature being "below", "below the bottom of", and "under the bottom of" the second feature includes that the first feature is directly below and obliquely below the second feature, or only means that the first feature is at a lower horizontal height than the second feature.
[0030] Please refer to Figure 1-7 As shown, a luffing mechanism for ultra-low space, in some embodiments, includes a slewing mechanism 1, a first oil cylinder 6 is arranged inside the slewing mechanism 1, both the slewing mechanism 1 and the first oil cylinder 6 are installed on a workbench (not shown in the figure), a first fixed seat 2 is installed on the slewing mechanism 1, the first fixed seat 2 is rotatably connected to a second fixed seat 3, a telescopic arm 4 is fixedly connected inside the second fixed seat 3, the other end of the telescopic arm 4 is connected to a hanging basket 5; the output end of the first oil cylinder 6 is connected to a first connecting shaft 7, and the first connecting shaft 7 is rotatably connected to the second fixed seat 3.
[0031] The luffing mechanism provided by the utility model drives the first fixed seat 2 and various structures above it to rotate through the slewing mechanism 1 to achieve the slewing function of the equipment. Since the first oil cylinder 6 is located inside the slewing mechanism 1, the installation and operation of the first oil cylinder 6 are not affected when the slewing mechanism 1 performs slewing operations. The first oil cylinder 6 is used to drive the first connecting shaft 7 to move up and down. Since the first connecting shaft 7 is rotatably connected to the second fixed seat 3, when the first connecting shaft 7 moves up and down, the second fixed seat 3 and the telescopic arm 4 rotate relative to the first fixed seat 2, so that the telescopic arm 4 can achieve an ultra-high luffing angle.
[0032] In some embodiments, the first fixed seat 2 is of a triangular structure, and an accommodation space 17 for accommodating part of the second fixed seat 3 and the telescopic arm 4 is provided inside it.
[0033] Further, a second connecting shaft 8 is provided at the upper end of the triangular first fixed seat 2. The second connecting shaft 8 passes through the second fixed seat 3 and the first fixed seat 2, and the first fixed seat 2 is rotatably connected to the second fixed seat 3 through the second connecting shaft 8.
[0034] In this embodiment, since the accommodation space 17 of the triangular first fixed seat 2 can accommodate part of the second fixed seat 3 and the telescopic arm 4, and the second fixed seat 3 rotates around the second connecting shaft 8 inside the upper end of the triangular first fixed seat 2, when the first oil cylinder 6 is in the retracted state, the telescopic arm 4 rotates to the horizontal state, which can greatly shorten the distance between the telescopic arm 4 and the slewing mechanism 1, thereby reducing the height of the luffing mechanism, so that the luffing mechanism can be suitable for ultra-low spaces and can pass through the height-limiting layer in the ultra-low retracted state. When the first oil cylinder 6 is in the extended state, the telescopic arm 4 can extend to an ultra-high size for working conditions. Thus, combined with the slewing mechanism 1 and with the size optimization of the space luffing, the luffing mechanism can achieve the luffing and slewing actions with maximum extension and minimum retraction.
[0035] In some embodiments, a third fixed seat 9 is fixedly connected to one end of the telescopic arm 4 away from the second fixed seat 3.
[0036] Further, a second oil cylinder 10 is installed in the third fixed seat 9. The output end of the second oil cylinder 10 is connected to a third connecting shaft 11. The third connecting shaft 11 is installed in a connecting seat 12, and the third connecting shaft 11 is rotatably connected to the connecting seat 12.
[0037] Further, the connecting seat 12 is fixedly connected to a fourth connecting shaft 13. The fourth connecting shaft 13 is installed in the third fixed seat 9, and the fourth connecting shaft 13 is rotatably connected to the third fixed seat 9.
[0038] Further, a fourth fixed seat 14 is fixedly connected to the fourth connecting shaft 13.
[0039] In this embodiment, the third connecting shaft 11 is rotatably connected to the connecting seat 12. The connecting seat 12 is fixedly connected to the fourth connecting shaft 13, and the fourth connecting shaft 13 is rotatably connected to the third fixed seat 9. When the second oil cylinder 10 drives the third connecting shaft 11 to move, the third connecting shaft 11 drives the fourth connecting shaft 13 to rotate through the connecting seat 12, causing the fourth connecting shaft 13 to rotate in the third fixed seat 9. Since the fourth connecting shaft 13 is fixedly connected to the fourth fixed seat 14, the fourth connecting shaft 13 drives the fourth fixed seat 14 to rotate.
[0040] In some embodiments, a rotary oil cylinder 16 is connected to the fourth fixed seat 14. The rotary oil cylinder 16 is connected to a fifth fixed seat 15, and the rotary oil cylinder 16 is used to drive the fifth fixed seat 15 to rotate.
[0041] Further, the fifth fixed seat 15 is fixedly connected to the hanging basket 5.
[0042] In this embodiment, the second oil cylinder 10 drives the fourth fixed seat 14, the fifth fixed seat 15, the rotary oil cylinder 16, and the hanging basket 5 to rotate around the fourth connecting shaft 13 to realize the up-and-down swinging operation of the hanging basket 5. The rotary oil cylinder 16 drives the fifth fixed seat 15 and the hanging basket 5 to rotate to realize the left-and-right swinging operation of the hanging basket 5. Thus, through the above design, the flexibility and adaptability of the equipment are improved.
[0043] Optionally, the slewing mechanism 1 is a hydraulic slewing bearing.
[0044] A luffing mechanism for ultra-low space provided by the present utility model drives the first fixed seat and each structure above it to rotate through the slewing mechanism to realize the slewing function of the equipment. When the first oil cylinder is in the retracted state, the telescopic arm rotates to the horizontal state, which can greatly shorten the distance between the telescopic arm and the slewing mechanism, thereby reducing the height of the luffing mechanism, so that the luffing mechanism can be suitable for ultra-low space and can pass through the height-limiting layer in the ultra-low retracted state. When the first oil cylinder is in the extended state, the telescopic arm can extend to a super-high size for working conditions, making the most of the space. Thus, the luffing mechanism combines with the slewing mechanism, and with the size optimization of the space luffing, it can realize the luffing and slewing actions with maximum extension and minimum retraction to meet the passing requirements of ultra-low and ultra-narrow spaces. Moreover, the luffing mechanism not only improves the flexibility and adaptability of the equipment, but also ensures the efficient coordination of the luffing and slewing actions without sacrificing the structural strength and stability. In addition, through the reasonable layout of the above structures, the luffing mechanism is compact in internal installation and more beautiful and generous in external form, meeting both the functional requirements and improving the user experience.
[0045] In summary, the luffing mechanism can take into account the passing ability in ultra-low and ultra-narrow spaces and the operation ability under efficient working conditions, which is of great significance for improving the equipment performance, reducing the operation difficulty and enhancing the safety.
