Description

Technical Field

[0001] This utility model relates to the field of hoisting operation technology, specifically an adjustable hoisting device structure for hoisting silicon cladding. Background Technology

[0002] In current silicon bundle lifting operations, existing lifting tools are significantly inadequate due to the substantial dimensional differences between silicon bundles of various specifications. Traditional lifting tools typically have fixed hook spacing, or their adjustment methods are extremely complex, time-consuming, and labor-intensive, making them unsuitable for the urgent needs of rapid and precise adjustments in actual production processes. This not only leads to low lifting efficiency but also increases the risk of damage to both the silicon bundle and the lifting tools during lifting due to size mismatch between the lifting tools and the silicon bundle, potentially resulting in serious safety accidents.

[0003] Various adjustable lifting device structures have been proposed in the existing technology. However, during the lifting process, the lifting device may sway due to changes in the center of gravity. At the same time, due to the adjustable position of the hook, it must be set on the lifting device in a movable connection manner. However, it is precisely because of the movable connection that the swaying of the lifting device and the change in the center of gravity during the lifting process will lead to the instability of the hook position, and in severe cases, the silicon cladding will slip off. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an adjustable lifting device structure for silicon ballast lifting, which can solve the problem that existing lifting devices cannot flexibly adapt to the lifting needs of silicon ballasts of different specifications, and at the same time ensure the stability of the lifting device during the silicon ballast lifting process and ensure the safety of the lifting operation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an adjustable lifting device structure for lifting silicon cladding, including a lifting device beam, two symmetrical slots on the bottom surface of the lifting device beam, a hook fixing seat installed in the slots, a hook at the bottom of the hook fixing seat, a horizontal rope drum in the middle of the lifting device beam, a vertical plate inside the lifting device beam on the top surface of the hook fixing seat, a traction rope on the vertical plate, one end of two traction ropes respectively connected and fixed to the two vertical plates, and the other end wound to both ends of the rope drum.

[0006] In a preferred embodiment, the top surface of the hook fixing seat is provided with a limiting plate, the width of which is greater than the width of the slot, and the limiting plate rests on the upper part of the slot.

[0007] In a preferred embodiment, the rope drum is driven by a motor mounted on the outside of one side of the lifting beam to achieve the winding and unwinding actions.

[0008] In a preferred embodiment, the two traction ropes are wound around the two ends of the rope drum in the same winding direction.

[0009] In a preferred embodiment, a counterweight is fixedly mounted on the outer side of the lifting beam opposite the location of the motor.

[0010] In a preferred embodiment, a guide rod is provided in the slot along the end of the lifting beam, the guide rod passes through the hook fixing seat part in the slot, and a spring is also sleeved on the guide rod;

[0011] The spring is sleeved on the guide rod section between the hook fixing seat and the center of the lifting beam.

[0012] In a preferred embodiment, a rack is provided on the bottom surface of the lifting beam, the rack is located on the side of the slot, and an electromagnetic lock is provided on the hook fixing seat located below the slot, with the electromagnetic lock tongue extending or retracting in the direction of the rack.

[0013] In a preferred embodiment, a rack is provided on each side of a single slot, and the electromagnetic lock is a double-headed electromagnetic lock structure. The two electromagnetic latches at both ends of the electromagnetic lock engage with the racks on the same side by extending outward.

[0014] The adjustable lifting device structure for transporting silicon cladding provided by this utility model has the following beneficial effects:

[0015] (1) The heat insulation board can effectively block the high-temperature fumes and splashes generated by the high-temperature liquid metal, thus providing effective protection for the upper hoisting equipment;

[0016] (2) The crossbeam of the lifting device is provided with slots, which, together with the rope drum, traction rope and hook fixing seat, can drive the rope drum by motor and adjust the position of the hook fixing seat on the crossbeam of the lifting device simultaneously, so as to adjust the distance between the two hooks and ensure that the center of gravity is centered. On the one hand, this lifting device can be adapted to the lifting of silicon clams of different specifications and sizes, without the need to frequently change the lifting device, which greatly improves the versatility and work efficiency of the lifting operation. On the other hand, it also ensures the stability of the center of gravity of the lifting device during the lifting process and avoids tilting.

[0017] (3) The guide rod and spring structure ensure that the position of the hook fixing seat is fixed after adjustment, and avoid the position displacement of the hook fixing seat caused by the shaking of the lifting device;

[0018] (4) By locking the electromagnetic lock and rack together, the position of the hook fixing seat is fixed after adjustment, reducing the tension of the motor caused by the spring force on the traction rope and extending the service life of the motor. Attached Figure Description

[0024] like Figure 1-3 In this invention, an adjustable lifting device structure for lifting silicon cladding includes a lifting device beam 1. Two slots 5 are symmetrically arranged on the bottom surface of the lifting device beam 1. A hook fixing seat 2 is installed in the slots 5. A hook 3 is arranged at the bottom of the hook fixing seat 2. A horizontal rope drum 9 is provided in the middle of the lifting device beam 1. A vertical plate 4 located inside the lifting device beam 1 is provided on the top surface of the hook fixing seat 2. A traction rope 8 is provided on the vertical plate 4. One end of the two traction ropes 8 is connected and fixed to the two vertical plates 4 respectively, and the other end is wound to both ends of the rope drum 9.

[0025] In a preferred embodiment, the top surface of the hook fixing seat 2 is provided with a limiting plate 201, the width of the limiting plate 201 is greater than the width of the slot 5, and the limiting plate 201 is placed on the upper part of the slot 5.

[0026] In a preferred embodiment, the rope drum 9 is driven by a motor 10 mounted on the outside of one side of the lifting beam 1 to perform the winding and unwinding actions.

[0027] In a preferred embodiment, the two traction ropes 8 are wound around the two ends of the rope drum 9 in the same winding direction.

[0028] In a preferred embodiment, a counterweight 11 is fixedly provided on the outer side of the other side of the lifting beam 1 opposite to the position of the motor 10.

[0029] In a preferred embodiment, a guide rod 6 is provided in the slot 5 along the end of the lifting beam 1. The guide rod 6 passes through the hook fixing seat 2 in the slot 5, and a spring 7 is also sleeved on the guide rod 6.

[0030] The spring 7 is sleeved on the guide rod 6 between the center of the hook fixing seat 2 and the center of the lifting beam 1.

[0031] In a preferred embodiment, a rack 12 is provided on the bottom surface of the lifting beam 1, the rack 12 is located on the side of the slot 5, and an electromagnetic lock 13 is provided on the hook fixing seat 2 located below the slot 5, the electromagnetic lock tongue 131 of the electromagnetic lock 13 is oriented toward the rack 12 in the extension and retraction direction.

[0032] In a preferred embodiment, a rack 12 is provided on each side of a single slot 5, and the electromagnetic lock 13 is a double-headed electromagnetic lock structure. The two electromagnetic lock tongues 131 at both ends of the electromagnetic lock 13 engage with the rack 12 on the same side by extending out.

[0033] The workflow and principle of silicon cladding hoisting using the adjustable hoisting structure provided by this utility model are as follows:

[0034] When hoisting standard-sized silicon casks, first move the lifting device to a suitable position above the silicon cask. At this time, start the motor 10 located outside one side of the lifting device's crossbeam. The motor 10 drives the rope drum 9 to rotate. Since the two traction ropes 8 are wound in the same direction on both ends of the rope drum 9, when the rope drum 9 rotates, the two traction ropes 8 synchronously pull the hook fixing seat 2 connected to the vertical plate 4 to move within the slot 5.

[0035] During the movement of the hook fixing seat 2, the guide rod 6 in the slot 5 plays a guiding role, ensuring that the hook fixing seat 2 moves smoothly along a straight line. At the same time, the spring 7 sleeved on the guide rod 6 provides buffering and forms elastic force, avoiding large impacts during the movement and ensuring that the positions of the two hook fixing seats 2 are symmetrical.

[0036] After the hook spacing is adjusted to the size of the appropriate silicon package, the electromagnetic lock 13 located on the hook fixing seat 2 is controlled to extend the electromagnetic lock tongue 131 at both ends of the double-headed electromagnetic lock structure and engage with the rack 12 on both sides of the slot 5 to firmly lock the hook fixing seat 2.

[0037] Subsequently, the operator uses hook 3 to hook the lifting point of the silicon package and starts the lifting equipment to carry out the lifting operation. During the lifting process, the limiting plate 201 on the top surface of the hook fixing seat 2 rests on the upper part of the slot 5 to prevent the hook fixing seat 2 from falling out of the slot 5; the counterweight block 11 on the opposite side of the motor 10 balances the weight of the motor, ensuring the stability of the lifting beam 1, and successfully completing the lifting of the standard specification silicon package.

[0038] When it is necessary to lift silicon balers of different sizes, for example, silicon balers that are wider than those lifted last time, first stop the lifting equipment, control the electromagnetic lock tongue 131 of the electromagnetic lock 13 to retract, and release the lock on the hook fixing seat 2. Then restart the motor 10, which drives the rope drum 9 to rotate in the opposite direction. The two traction ropes 8 are released, and with the assistance of the restoring force of the spring 7, the hook fixing seat 2 moves to both sides along the guide rod 6, increasing the hook spacing.

[0039] Based on the actual width of the silicon package, observe the adjustment of the hook spacing. Once a suitable spacing is achieved, control the electromagnetic lock 13 again, causing the electromagnetic lock tongue 131 to extend and engage with the rack 12, thus fixing the hook fixing seat 2. Next, use the hook 3 to hook the silicon package for lifting. This process, driven by a motor and locked by an electromagnetic lock, enables rapid adjustment and lifting of silicon packages of different sizes, greatly improving lifting efficiency.
