[0034] In the production process of high-purity aluminum, the traditional way of crucible ingot transfer is to manually operate the outer-circle clamping forklift to achieve the transfer of crucible ingots between multiple devices and intermediate warehouses. However, in the traditional technology, firstly, the number of crucible ingots is large and the transfer frequency is high, resulting in a relatively high labor intensity for workers, which is prone to work fatigue and safety problems. Secondly, during the transfer of crucible ingots by manually operating the outer-circle clamping forklift, multiple production areas are involved, which increases the safety hazards during the transfer process of crucible ingots. Moreover, since the production beats of the purification equipment are usually inconsistent, there is a waiting phenomenon when manually operating the outer-circle clamping forklift to transfer crucible ingots, which in turn leads to low transfer efficiency of crucible ingots and affects the purification production efficiency. An overhead crane automatic lifting clamping spreader provided in this application can be applied to the overhead crane automatic lifting equipment to achieve the automatic transfer of crucible ingots, reduce the operation intensity, and ensure the safety of the crucible ingot transfer process. At the same time, the overhead crane automatic lifting clamping spreader can achieve the automatic clamping of crucible ingots, and the overhead crane automatic lifting equipment can set the transfer time of crucible ingots according to the production beat of the purification equipment. Therefore, when the crucible ingots are transferred, the time redundancy can be reduced and the transfer efficiency of crucible ingots can be improved.

[0035] In an exemplary embodiment, an overhead crane automatic lifting clamping spreader is provided, as Figure 1 shown, which is a schematic structural diagram of the overhead crane automatic lifting clamping spreader 10, including: a base plate 100, a lifting mechanism 200, a clamping mechanism 300, and a centering mechanism 400; the base plate 100 is used to be connected to the lifting mechanism 200 and the overhead crane automatic lifting equipment (not shown in the figure); the lifting mechanism 200 is used to drive the clamping mechanism 300 to move; the clamping mechanism 300 is connected to the lifting mechanism 200, and the clamping mechanism 300 is used to generate a clamping force; the centering mechanism 400 is fixedly connected to the clamping mechanism 300, and the centering mechanism 400 is used to receive the clamping force generated by the clamping mechanism 300 and clamp the target device 20 under the action of the clamping force.

[0036] Optionally, the first surface of the substrate 100 is connected to the overhead crane automatic lifting equipment. The connection position of the substrate 100 on the overhead crane automatic lifting equipment is set according to actual needs and is not limited herein. The first surface of the substrate 100 can be fixedly connected to the spreader mounting plate of the overhead crane automatic lifting equipment. When the overhead crane automatic lifting equipment moves, it can drive the substrate 100 to move accordingly, and then drive the overhead crane automatic lifting clamp spreader 10 to move. The connection method between the first surface of the substrate 100 and the spreader mounting plate of the overhead crane automatic lifting equipment can be bolt connection, snap connection, welding, etc. The shape and manufacturing material of the substrate 100 are not limited herein, as long as it can bear the weight of the overhead crane automatic lifting clamp spreader 10 and be fixedly connected to the overhead crane automatic lifting equipment. Exemplarily, the shape of the substrate 100 can be square, circular, etc., and the manufacturing material of the substrate 100 can be steel plate, aluminum alloy, etc.

[0037] The second surface of the substrate 100 is connected to the lifting mechanism 200. The second surface of the substrate 100 and the lifting mechanism 200 can be connected by means of slot connection, locking device, fixture connection, etc. The lifting mechanism 200 is used to drive the clamping mechanism 300 to move. The lifting mechanism 200 can be a chain lifting device, a hydraulic lifting device or a screw lifting device. The lifting mechanism 200 is used to drive the clamping mechanism 300 to move longitudinally. Exemplarily, the lifting mechanism 200 can be connected to a controller, and the controller is used to send control instructions to the lifting mechanism 200 to make the lifting mechanism 200 move longitudinally according to the control instructions, and then drive the clamping mechanism 300 to move. A through hole or slot can be provided at the lower end of the lifting mechanism 200, and the clamping mechanism 300 can be fixedly connected to the through hole or slot of the lifting mechanism 200 by pins, screws or bolts.

[0038] The clamping mechanism 300 can be fixedly connected to the through hole or slot of the lifting mechanism 200 by pins, screws or bolts. When the lifting mechanism 200 moves longitudinally, it can drive the clamping mechanism 300 to move. When the lifting mechanism 200 moves upward, the clamping mechanism 300 can generate a clamping force. The clamping mechanism 300 can conduct the clamping force to the centering mechanism 400, and the centering mechanism 400 realizes the clamping of the target device through the clamping force. The target device can be a crucible ingot.

[0039] In this embodiment, the overhead crane automatic lifting clamping sling is connected to the overhead crane automatic lifting equipment through the substrate. When the overhead crane automatic lifting equipment moves, it can drive the overhead crane automatic lifting clamping sling to move. The substrate is also connected to the lifting mechanism, and the lifting mechanism is connected to the clamping mechanism, which is used to drive the clamping mechanism to move and generate a clamping force on the target equipment (such as a crucible ingot), so as to clamp the target equipment. Therefore, the overhead crane automatic lifting clamping sling can be applied to the overhead crane automatic lifting equipment to realize the automatic transfer of the target equipment (such as a crucible ingot), reduce the manual operation intensity, and improve the safety of the transfer process of the target equipment (such as a crucible ingot).

[0040] In an exemplary embodiment, as Figure 2 shown in the structural detail diagram of the overhead crane automatic lifting clamping sling 10, the substrate 100 includes mounting holes 102 and a plurality of connecting ear rings.

[0041] Optionally, two connecting ear rings 104 and 106 are provided on the substrate 100. The connecting ear rings 104 and 106 can be fixedly connected to the second surface of the substrate 100 by means of screw connection, welding, etc. The mounting holes 102 and the connecting ear rings 104 and 106 can be arranged symmetrically along a straight line, so that the mounting holes 102 are located at the center point of the connection line of the connecting ear rings 104 and 106, which can ensure the uniform distribution of the load on the substrate 100. The shapes of the connecting ear rings 104 and 106 can be annular or square, and through holes are provided at the bottoms thereof for connecting with other mechanisms. The manufacturing materials of the connecting ear rings 104 and 106 can be stainless steel, aluminum alloy, etc. The connecting ear rings 104 and 106 can also be hinge ear rings.

[0042] In the previous exemplary embodiment, a plurality of connecting ear rings and the mounting holes 102 are provided on the lower surface of the substrate 100, and the substrate 100 is connected to the lifting mechanism 200 through the mounting holes 102.

[0043] A plurality of connecting ear rings (104 and 106) and the mounting holes 102 are provided on the lower surface of the substrate 100 (i.e., the second surface of the substrate 100). The first end of the lifting mechanism 200 is connected to the mounting holes 102. Optionally, the first end of the lifting mechanism 200 can be provided with threads, and the mounting holes 102 can be corresponding threaded holes. Screwing the first end of the lifting mechanism 200 into the mounting holes 102 can ensure the stable connection between the lifting mechanism 200 and the substrate 100. The first end of the lifting mechanism 200 and the mounting holes 102 can also be fixedly connected by means of clamping, fixture fixing, etc.

[0044] In this embodiment, multiple connecting earrings and mounting holes are provided on the lower surface of the substrate for connecting with the lifting mechanism and other mechanisms, and can drive the lifting mechanism and other mechanisms to move while the substrate is moving. The substrate is connected to the lifting mechanism through the mounting holes, which can ensure the stable connection between the lifting mechanism and the substrate.

[0045] In an exemplary embodiment, please refer again to Figure 1 and Figure 2 , the overhead crane automatic lifting clamp lifting tool 10 further includes a connecting mechanism 500. The connecting mechanism 500 includes multiple groups of connecting rods. The first ends of the multiple groups of connecting rods are correspondingly connected to multiple connecting earrings (104 and 106), and the second ends of each group of connecting rods 502 are connected to the clamping mechanism 300.

[0046] Optionally, the connecting mechanism 500 may include two groups of connecting rods 502 and 504, and the connecting rods 502 and 504 are symmetrically distributed with the lifting mechanism 200 as the central axis. Through holes are provided at both ends of the connecting rods 502 and 504. Exemplarily, through holes are provided at the bottoms of the connecting earrings 104 and 106. The first end of the connecting rod 502 and the connecting earring 104 are connected through the through hole at the first end of the connecting rod 502 and the through hole at the bottom of the connecting earring 104. The first end of the connecting rod 502 may also be provided as a reamed hole, and the connecting earring 104 may also be a hinge shaft earring. The reamed hole at the first end of the connecting rod 502 and the hinge shaft earring of the connecting earring 104 are connected through a hinge shaft 30. The second end of the connecting rod 502 can establish a connection with the clamping mechanism 300 through the through hole at the second end of the connecting rod 502. The connection manner between the connecting rod 504 and the connecting earring 106 is similar to the connection manner between the connecting rod 502 and the connecting earring 104, and will not be elaborated here. The shapes of the connecting rods 502 and 504 can be set as oblong, rectangular, etc. The connecting rods 502 and 504 can be made of materials such as aluminum alloy and steel, which can ensure the strength and wear resistance of the connecting rods 502 and 504.

[0047] The upper part of the connecting mechanism 500 is used to connect the substrate 100, the lower part of the connecting mechanism 500 is used to connect the clamping mechanism 300, and the connecting mechanism 500 is also used to provide clamping movement and clamping force for the clamping mechanism 300.

[0048] In this embodiment, the connecting mechanism includes multiple groups of connecting rods, and the two ends of each group of connecting rods are respectively connected to the connecting earring and the clamping mechanism, which can generate a clamping force between the clamping mechanism and the substrate.

[0049] In an exemplary embodiment, the clamping mechanism 300 includes multiple groups of clamping plates, and each group of clamping plates is cross-connected.

[0050] Optionally, the clamping mechanism 300 may include two sets of clamping plates, namely clamping plate 302 and clamping plate 304. A connection is maintained between the middles of clamping plate 302 and clamping plate 304, such that clamping plate 302 and clamping plate 304 form a scissor cross-shaped structure. Clamping plate 302 and clamping plate 304 are symmetrically distributed with the lifting mechanism 200 as the central axis. The first ends of clamping plate 302 and clamping plate 304 may be set to be oblong or rectangular, and the second ends of clamping plate 302 and clamping plate 304 may be set to be hook-tailed, so as to form an opening at the second ends of clamping plate 302 and clamping plate 304, and the target device can be clamped using this opening. For example, when the overhead crane automatically hoists and clamps the target device with the clamping sling 10, the second ends of clamping plate 302 and clamping plate 304 can clamp and fix the target device. Clamping plate 302 and clamping plate 304 can be made of materials such as aluminum alloy and steel, which can ensure the strength and wear resistance of clamping plate 302 and clamping plate 304.

[0051] In an exemplary embodiment, connection holes 306 are correspondingly provided in the middles of each group of clamping plates, and each group of clamping plates are cross-connected through the connection holes 306; the clamping mechanism is connected to the lifting mechanism 200 through the connection holes 306.

[0052] Exemplarily, each group of clamping plates are clamping plate 302 and clamping plate 304, and connection holes 306 are provided at preset positions in the middles of clamping plate 302 and clamping plate 304, and the preset positions are set according to actual situations. After accurately aligning the connection holes 306 of clamping plate 302 and clamping plate 304, connecting members such as bolts, hinge shafts or hinges are passed through the connection holes 306 to connect clamping plate 302 and clamping plate 304, forming a scissor cross-shaped structure, which can ensure the flexibility of clamping plate 302 and clamping plate 304 while stably connecting clamping plate 302 and clamping plate 304. At the same time, a through hole may be provided at the lower end of the lifting mechanism 200. Before passing connecting members such as bolts, hinge shafts or hinges through the connection holes 306, the through hole at the lower end of the lifting mechanism 200 is accurately aligned with the connection holes 306, and connecting members such as bolts, hinge shafts or hinges are passed through the connection holes 306 and the through hole at the lower end of the lifting mechanism 200, so that clamping plate 302 and clamping plate 304 form a scissor cross-shaped structure and at the same time connect the clamping mechanism to the lifting mechanism 200.

[0053] In this embodiment, the clamping mechanism includes multiple groups of clamping plates, each group of clamping plates are cross-connected through connection holes, and the clamping mechanism is connected to the lifting mechanism through the connection holes, which can ensure the flexibility between each group of clamping plates, and further realize the clamping of the target device. At the same time, the clamping mechanism is connected to both the lifting mechanism and the connection mechanism, which can enhance the stability of the overhead crane's automatic hoisting and clamping sling.

[0054] In the previous exemplary embodiment, the first ends of multiple groups of clamping plates are correspondingly connected to the second ends of multiple groups of connecting rods.

[0055] The multiple sets of clamping plates include clamping plate 302 and clamping plate 304, and the multiple sets of connecting rods include connecting rod 502 and connecting rod 504. Through holes are provided at the second ends of connecting rod 502 and connecting rod 504, and corresponding through holes are provided at the first ends of clamping plate 302 and clamping plate 304. The through holes can be hinge holes. Exemplarily, after precisely aligning the through hole at the first end of clamping plate 302 with the through hole at the second end of connecting rod 504, a connecting member such as a bolt, hinge shaft or hinge is passed through the through holes of both, so that the first end of clamping plate 302 is connected to the second end of connecting rod 504, which can ensure the flexibility of clamping plate 302 and connecting rod 504 while stably connecting the first end of clamping plate 302 and the second end of connecting rod 504. The connection method between the first end of clamping plate 304 and the second end of connecting rod 502 is similar to the connection method between the first end of clamping plate 302 and the second end of connecting rod 504, and will not be elaborated here.

[0056] In the previous exemplary embodiment, hinge holes are correspondingly provided at the first ends of each group of clamping plates and the second ends of each group of connecting rods, and the first ends of the multiple sets of clamping plates are correspondingly connected to the second ends of the multiple sets of connecting rods through the hinge holes.

[0057] The through holes at the second ends of connecting rod 502 and connecting rod 504 and the through holes at the first ends of clamping plate 302 and clamping plate 304 are set as hinge holes. Exemplarily, the hinge hole at the first end of clamping plate 302 is connected to the hinge hole at the second end of connecting rod 504 through hinge shaft 8.

[0058] In this embodiment, the first ends of the multiple sets of clamping plates and the second ends of the multiple sets of connecting rods are connected through a hinge shaft, so that the vertical pulling force of the connecting mechanism can be transmitted to the clamping mechanism, and further the vertical pulling force of the connecting mechanism can be converted into the clamping force of the clamping mechanism to achieve effective clamping of the clamping mechanism.

[0059] In an exemplary embodiment, the centering mechanism 400 includes multiple sets of jaw members, and a nail plate 406 is fixedly provided on each set of jaw members; under the action of the clamping force, each nail plate 406 is fixedly connected to the target device 20.

[0060] The centering mechanism 400 is in a dovetail shape. The centering mechanism 400 includes two sets of jaw members 402 and 404. The jaw member 402 is arranged at the bottom of the second end of the clamping plate 302, and the jaw member 402 is fixedly connected to the clamping plate 302. The jaw member 404 is arranged at the bottom of the second end of the clamping plate 304, and the jaw member 404 is fixedly connected to the clamping plate 304. The jaw member 402 and the jaw member 404 are symmetrically distributed with respect to the central axis of the lifting mechanism 200. A nail plate 406 is fixedly provided on the surface of the jaw member 402 and the jaw member 404 facing the target device 20, and the nail plate 406 is a nail plate clamping panel.

[0061] The centering mechanism 400 is used to receive the clamping force generated by the clamping mechanism 300 and conduct the clamping force onto the jaw members 402 and 404. Under the action of this clamping force, the nail plates 406 on the jaw members 402 and 404 can be embedded into the target device (such as a crucible ingot), and then the target device (such as a crucible ingot) can be firmly clamped. Moreover, the centering mechanism 400 is in the shape of a dovetail, and can correct the deviation of the jaw members 402 and 404 when the clamping mechanism 300 performs a clamping action, so that the jaw members 402 and 404 can accurately clamp the center of the target device (such as a crucible ingot), thereby avoiding the hanging deviation and hanging skew of the target device (such as a crucible ingot).

[0062] In the previous exemplary embodiment, each group of jaw members and the clamping mechanism are connected through a hinge shaft or a hinge.

[0063] The jaw member 402 is arranged at the bottom of the second end of the clamping plate 302. The jaw member 402 and the clamping plate 302 can be fixedly connected through a hinge shaft or a hinge. The jaw member 404 is arranged at the bottom of the second end of the clamping plate 304. The jaw member 404 and the clamping plate 304 can be fixedly connected through a hinge shaft or a hinge.

[0064] In this embodiment, the centering mechanism is connected to the clamping mechanism, and is used to receive the clamping force generated by the clamping mechanism and conduct it to each group of jaw members. Under the action of this clamping force, each group of jaw members can firmly clamp the target device (such as a crucible ingot); at the same time, through the dovetail-shaped centering mechanism, the deviation of each group of jaw members can be corrected, and then the center of the target device (such as a crucible ingot) can be accurately clamped, ensuring the safety of transporting the target device (such as a crucible ingot).

[0065] In an exemplary embodiment, an overhead crane automatic lifting device is proposed, which includes the above-mentioned overhead crane automatic lifting clamping sling. Exemplarily, the overhead crane automatic lifting device includes a controller, which is used to control the overhead crane automatic lifting device to automatically transfer the target device (such as a crucible ingot). At the same time, the controller can also be connected to the lifting mechanism, and is used to transmit control instructions to the lifting mechanism to control the lifting mechanism to move longitudinally, so as to realize the clamping of the target device (such as a crucible ingot).

[0066] In another embodiment, an overhead crane automatic lifting clamping sling is provided, and the sling includes:

[0067] A substrate, which is used to be connected to the lifting mechanism and the overhead crane automatic lifting device; the substrate includes mounting holes and a plurality of connecting ear rings.

[0072] In this embodiment, multiple connecting ear rings and mounting holes are arranged on the lower surface of the substrate, used for connecting with the lifting mechanism and other mechanisms, and can drive the lifting mechanism and other mechanisms to move while the substrate is moving. The clamping mechanism includes multiple groups of clamping plates, and each group of clamping plates are cross-connected through connection holes, and the clamping mechanism is connected to the lifting mechanism through the connection holes, which can ensure the flexibility between each group of clamping plates, and then realize the clamping of the target device. The first ends of multiple groups of clamping plates and the second ends of multiple groups of connecting rods are connected through a hinge shaft, so that the vertical pulling force of the connecting mechanism can be transmitted to the clamping mechanism, and then the vertical pulling force of the connecting mechanism can be converted into the clamping force of the clamping mechanism, realizing the effective clamping of the clamping mechanism. The centering mechanism is connected to the clamping mechanism, used to receive the clamping force generated by the clamping mechanism and conduct it to each group of jaw parts, and under the action of this clamping force, each group of jaw parts can firmly clamp the target device (such as a crucible ingot), and then realize the automatic transfer of the target device (such as a crucible ingot), reduce the manual operation intensity, and then improve the safety of the transfer process of the target device (such as a crucible ingot).
