Description

Technical Field

[0001] This utility model patent relates to an assembled anti-tipping lotus grab transfer tool, belonging to the field of excavator attachment shipping technology. Background Technology

[0002] Medium and large excavators often require the removal of the lotus grab handle for shipment due to transportation restrictions. Current long-distance transport methods for lotus grab handles primarily involve placing the handle open and upright or closed and then flattened on a wooden pallet. With the handle upright, forklifts cannot be used, requiring hoisting. This method is unsuitable when transporting by roll-on / roll-off ships or in environments lacking hoisting capabilities. Furthermore, wooden pallets are easily damaged during transport, causing the lotus grab handle to shift and tip over, damaging it. Additionally, placing the handle in its closed state is extremely difficult, leading to prolonged operation and impacting shipping efficiency. Summary of the Invention

[0003] This utility model provides a prefabricated anti-tipping lotus grab transfer fixture, which is suitable for vertical lotus grab transfer and can be adapted to both forklift and hoisting methods, so as to solve the technical problems existing in the current lotus grab transfer.

[0004] This utility model is achieved according to the following technical solution: A prefabricated anti-tipping lotus gripper transfer fixture includes: A load-bearing chassis for holding lotus grippers to be transferred, and a forklift slot is reserved in the load-bearing chassis; Two connecting columns are symmetrically arranged on both sides of the load-bearing chassis. The longitudinal cross-section of the two connecting columns and the load-bearing chassis forms a U-shape. Each of the two connecting columns has a coaxially arranged connecting hole I at its top. The lotus-shaped grab has a connecting hole II at its top. The connecting shaft passes through the aligned connecting hole II and the two connecting holes I, serving two purposes: firstly, to connect the lotus gripper to the transfer fixture, and secondly, to act as a lifting point. Multiple limit clamping plate assemblies are fixed on the load-bearing chassis and surround the lotus grab in the upright position, limiting the middle part of the lotus grab in multiple directions; Multiple anti-tipping limit supports are fixed to the load-bearing chassis and surround the lotus grab in the upright position, limiting the bottom part of the lotus grab in multiple directions.

[0005] In some embodiments, the connecting column is an adjustable structure, and its height can be adjusted according to the different sizes of lotus-shaped catches so that connecting hole I is aligned with connecting hole II.

[0006] In some embodiments, the connecting column includes column I, column II, and a locking component; column I is fixed on the load-bearing chassis, column II is inserted into column I, and column II can move up and down in column I; the upper part of column I is provided with at least one insertion hole I, and the lower middle part of column II is provided with multiple insertion holes II arranged vertically at intervals; the locking component consists of bolts and bolts or pins and cotter pins. By moving column I up and down to adjust column I to a height that matches the lotus clamp to be shipped, bolts or pins are inserted into the aligned insertion holes I and insertion holes II, and the bolts or cotter pins are axially limited by bolts or cotter pins.

[0007] In some embodiments, the limiting clamping plate assembly includes: Support column, which is fixed to the load-bearing chassis; The clamping plate is placed in the groove on the upper part of the clamping arm in the lotus gripper; An adjusting component is connected between the clamping plate and the support column, and the clamping plate is pressed tightly against the inner wall of the groove by the adjusting component.

[0008] In some embodiments, the adjusting component includes: A threaded block is fixed to the clamping plate on the side facing the support column; The bolt is inserted into the through hole at the top of the support column, and the front end of the bolt is screwed into the threaded block. The two form a helical pair. By rotating the bolt, the clamping plate can be moved outward or inward along the axial direction of the bolt. A lock nut, installed on the bolt, is used to secure the bolt to the support column.

[0009] In some embodiments, the clamping plate has a polyurethane board attached to the portion that contacts the lotus-shaped clamp.

[0010] In some embodiments, the anti-tipping limiting support is a П-shaped support, and the top plate of the П-shaped support is set as an inclined plate. After the lotus grab to be transferred is placed on the load-bearing chassis, the inclined plate of the anti-tipping limiting support is pressed against the clamp arm in the lotus grab, and the two upright plates of the П-shaped support are welded to the load-bearing chassis.

[0011] In some embodiments, a polyurethane board is attached to the inclined plate of the anti-tipping limiting support.

[0012] In some embodiments, the load-bearing chassis consists of an upper frame, a lower frame, and an intermediate support rod connecting the upper and lower frames; the connecting column, the limiting clamping plate assembly, and the anti-tipping limiting support are all fixed on the upper frame, and the gap between the upper and lower frames is used as the forklift slot.

[0013] In some embodiments, each end of the connecting shaft is provided with a radial through hole at the part extending from the connecting hole I at the top of the connecting column. A bolt or pin is inserted into the radial through hole, and the bolt or pin is axially limited by the bolt or cotter pin.

[0014] The beneficial effects of this utility model are: 1. Multi-model compatibility and high versatility: Adopting a modular assembly design, the height can be flexibly adjusted through the adjustable connecting column. Combined with the detachable limit clamping plate assembly and anti-tipping support, it can achieve precise matching of tooling with different specifications of lotus grippers, breaking the traditional tooling single-model limitation and reducing costs.

[0015] 2. Dual-mode transfer overcomes scenario limitations: The chassis has a forklift slot to support ground forklift transport; the connecting shaft serves as both a structural connection and a lifting point, supporting lifting operations. This design completely solves the pain point of traditional upright placement relying on lifting, and is especially suitable for complex working conditions such as roll-on / roll-off ship transportation and ports without lifting equipment, improving shipping flexibility.

[0016] 3. Comprehensive protection ensures safety: 1) Triple stabilization mechanism: The iron frame load-bearing chassis has strong impact resistance, the three-point limit clamping inhibits displacement, and the anti-tipping support is reinforced by welding, which greatly reduces the risk of overturning during transportation. 2) Paint protection design: A polyurethane buffer layer is pasted on the contact surface of the clamping plate and the support to avoid paint damage caused by the wear and tear of traditional wooden supports, and reduce rework costs.

[0017] 4. Significantly improved work efficiency: 1) The upright position is fixed directly, eliminating the time-consuming operation of repeatedly opening and closing the lotus claw and adjusting the flat position; 2) Prefabricated components support quick assembly and disassembly, simplifying storage and turnover processes and shortening the shipping cycle by more than 30%.

[0018] In summary, this shipping tooling, with its core features of "universal adaptability, multi-mode transfer, enhanced protection, and efficient operation," systematically solves the problems of tipping risk, scenario limitations, and low efficiency inherent in traditional solutions, providing reliable technical support for the cross-border transportation of large attachments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an assembled anti-tipping lotus grab transfer fixture includes a load-bearing chassis 1, two connecting columns 2, a connecting shaft 5, multiple limit clamping plate assemblies 3, and multiple anti-tipping limit supports 4. The load-bearing chassis 1 is used to hold the lotus grab to be transferred, and a forklift slot is reserved in the load-bearing chassis 1. The two connecting columns 2 are symmetrically arranged on both sides of the load-bearing chassis 1, and the longitudinal section of the two connecting columns 2 and the load-bearing chassis 1 is U-shaped. Each of the two connecting columns 2 has a coaxially arranged connecting hole I at its top. The top is provided with a connecting hole II; the connecting shaft 5 passes through the aligned connecting hole II and two connecting holes I, which serves to connect the lotus gripper to the transfer tool and to act as a lifting point; multiple limit clamping plate assemblies 3 are fixed on the load-bearing chassis 1 and surround the lotus gripper in the upright position, limiting the middle part of the lotus gripper in multiple directions; multiple anti-tipping limit supports 4 are fixed on the load-bearing chassis 1 and surround the lotus gripper in the upright position, limiting the bottom part of the lotus gripper in multiple directions.

[0027] As can be seen from the above, the prefabricated design, through the flexible combination of different components, can be adapted to transport and ship various models of lotus grabs; the tooling is connected to the lotus grab by inserting a prefabricated iron connecting shaft through the pin hole of the lotus grab; the lotus grab is fixed at three points by the prefabricated limit clamping plate assembly. The tooling is highly flexible, the limit is reliable, and the operation is simple. It is also compatible with both forklift and hoist transport methods. Moreover, the iron tooling frame is strong and not easily damaged during the transport process, and the lotus grab is not easy to tip over, which can protect the lotus grab to the greatest extent.

[0028] The following provides a further explanation of the specific structure of the aforementioned connecting columns.

[0029] The connecting column 2 is an adjustable structure. Its height can be adjusted according to the different sizes of the lotus gripper to align the connecting hole I with the connecting hole II, so as to meet the connection requirements between the lotus gripper and the transfer tool.

[0030] A further embodiment includes a connecting column 2 comprising a column I, a column II, and a locking component; column I is fixed to a load-bearing chassis, column II is inserted into column I, and column II can move up and down within column I; column I has at least one insertion hole I at its upper part, and column II has multiple insertion holes II arranged vertically at intervals at its lower middle part; the locking component consists of bolts and bolts or pins and cotter pins. By moving column I up and down to adjust column I to a height matching the pre-shipment lotus clamp, bolts or pins are inserted into the aligned insertion holes I and II, and the bolts or cotter pins are axially limited.

[0031] It should be noted that in practical applications, when adjusting column I to match the height of the lotus grabber to be shipped, if there is no insertion hole II that is aligned with insertion hole I, an electric drill can be used to drill an insertion hole II that is coaxial with insertion hole I on column II.

[0032] Further options, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a diagonal support is fixed between the connecting column and the chassis.

[0033] The following provides a further explanation of the specific structure of the aforementioned limit clamping plate assembly.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the limiting clamping plate assembly 3 includes a support column 31, a clamping plate 32, and an adjusting component; the support column 31 is fixed on the load-bearing chassis 1; the clamping plate 32 is placed in the groove on the upper part of the clamping arm in the lotus gripper; the adjusting component is connected between the clamping plate 32 and the support column 31, and the clamping plate 32 is pressed tightly against the inner wall of the groove by the adjusting component.

[0035] Further options, such as Figure 5As shown, the adjusting components include a threaded block 33, a bolt 34, and a locking nut 35; the threaded block 33 is fixed to the clamping plate 32 on the side facing the support column 31; the bolt 34 is inserted into the through hole at the top of the support column 31, and the front end of the bolt 34 is screwed into the threaded block 33, forming a helical pair between the two. By rotating the bolt 34, the clamping plate 32 is moved outward or inward along the axial direction of the bolt 34; the locking nut 35 is installed on the bolt 34 to fix the bolt 34 to the support column 31.

[0036] Further options, such as Figure 5 As shown, a polyurethane plate 36 is attached to the part of the clamping plate 32 that contacts the lotus-shaped clamp.

[0037] As can be seen from the above, the limiting clamping plate assembly limits the lotus grabber through the adjustable screw, forming a three-point limiting to ensure the stability of the lotus grabber during transportation. The clamping plate is attached with a polyurethane board to ensure that the paint surface of the lotus grabber is not damaged.

[0038] The following provides a further explanation of the specific structure of the aforementioned anti-tipping limit support.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, the anti-tipping limit support 4 is a П-shaped support, and the top plate of the П-shaped support is set as an inclined plate. After the lotus grab to be transferred is placed on the load-bearing chassis 1, the inclined plate of the anti-tipping limit support 4 is pressed against the clamp arm in the lotus grab, and the two upright plates of the П-shaped support are welded to the load-bearing chassis 1.

[0040] A further solution is to attach a polyurethane board to the inclined plate of the anti-tipping limit support 4.

[0041] As can be seen from the above, the anti-tipping limit support is used to prevent the lotus grab from tipping over. Its material and structure can keep the lotus grab stable during transportation. The welding design selects the appropriate position according to the state of the lotus grab after placement, increasing flexibility. The polyurethane board pasted on the support ensures that the paint surface of the lotus grab is not damaged.

[0042] The following provides a further explanation of the specific structure of the aforementioned connecting shaft.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown, each end of the connecting shaft 5 has a radial through hole at the part extending from the connecting hole I at the top of the connecting column 2. Bolts or pins are inserted into the radial through holes, and the bolts or cotter pins are used to axially limit the bolts or pins.

[0044] As can be seen from the above, the connecting shaft is used to connect the lotus claw and the tooling during overall lifting. At the same time, the high-strength material can be used as a lifting point and is fixed to the connecting column by bolts.

[0045] The following provides a further explanation of the specific structure of the aforementioned load-bearing chassis.

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the load-bearing chassis 1 consists of an upper frame 11, a lower frame 12, and an intermediate support rod 13 connecting the upper and lower frames 11 and 12; the connecting column 2, the limiting clamping plate assembly 3, and the anti-tipping limiting support 4 are all fixed on the upper frame 11, and the gap between the upper and lower frames 11 and 12 is used as a forklift slot.

[0047] As can be seen from the above, the load-bearing base is used to support the weight of the Lotus gripper during transportation. Its material and structural form can keep the overall tooling stable during the shipping process, and a forklift slot is reserved for forklift transfer.

[0048] In summary, this utility model provides a prefabricated anti-tipping lotus gripper transfer fixture, which achieves the following functions and effects: 1. Multi-model compatibility and high versatility: Adopting a modular assembly design, the height can be flexibly adjusted through the adjustable connecting column. Combined with the detachable limit clamping plate assembly and anti-tipping support, it can achieve precise matching of tooling with different specifications of lotus grippers, breaking the traditional tooling single-model limitation and reducing costs.

[0049] 2. Dual-mode transfer overcomes scenario limitations: The chassis has a forklift slot to support ground forklift transport; the connecting shaft serves as both a structural connection and a lifting point, supporting lifting operations. This design completely solves the pain point of traditional upright placement relying on lifting, and is especially suitable for complex working conditions such as roll-on / roll-off ship transportation and ports without lifting equipment, improving shipping flexibility.

[0050] 3. Comprehensive protection ensures safety: 1) Triple stabilization mechanism: The iron frame load-bearing chassis has strong impact resistance, the three-point limit clamping inhibits displacement, and the anti-tipping support is reinforced by welding, which greatly reduces the risk of overturning during transportation. 2) Paint protection design: A polyurethane buffer layer is pasted on the contact surface of the clamping plate and the support to avoid paint damage caused by the wear and tear of traditional wooden supports, and reduce rework costs.

[0051] 4. Significantly improved work efficiency: 1) The upright position is fixed directly, eliminating the time-consuming operation of repeatedly opening and closing the lotus claw and adjusting the flat position; 2) Prefabricated components support quick assembly and disassembly, simplifying storage and turnover processes and shortening the shipping cycle by more than 30%.
