Description

Technical Field

[0001] The utility model relates to the technical field of nonferrous metal smelting, in particular to a zinc ingot stack transfer sling. Background Art

[0002] During the zinc ingot production process, individual zinc ingots are stacked and bundled into zinc ingot stacks on the stacking production line. When the zinc ingot stacks come off the stacking production line, in order to save time, chains are usually used to lift the two stacks of zinc ingots from the stacking production line to the zinc ingot storage area. During the chain lifting process, due to the uneven force on the bottom of the two zinc ingot stacks, the two zinc ingot stacks will be squeezed against each other and become skewed, which will not only affect the product quality, but also cause the zinc ingot stacks lifted to the storage area to be unevenly placed, thereby reducing the space utilization of the zinc ingot storage area and reducing the number of zinc ingots stored in the storage area.

[0003] Therefore, there is an urgent need for a zinc ingot stack transfer hoist that has high transfer efficiency, does not squeeze the zinc ingots during the process of lifting the zinc ingot stack, and keeps the zinc ingot stack neat as a whole. Summary of the Invention

[0004] In order to solve the problem in the prior art that zinc ingot stacks are squeezed against each other and become skewed during the transfer process, the utility model provides a zinc ingot stack transfer sling, which ensures that the zinc ingot stacks are always kept neat and not squeezed against each other during the process of being lifted from the production line to the storage area. While improving the transfer efficiency, the space utilization efficiency of the zinc ingot storage area is also improved.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] A zinc ingot stack transfer sling comprises a crossbeam with multiple sets of slings arranged parallel to each other along its length. The sling comprises fixed arms connected to the crossbeam, each fixed arm having a clamping arm rotatably connected at both ends. The clamping arm has an inclined upper portion and an L-shaped lower portion. The two clamping arms connected to each fixed arm intersect and are symmetrically arranged along the centerline of the crossbeam. The multiple clamping arms arranged parallel to each other along the length of the crossbeam are fixedly connected by a connector. The clamping arms are used to clamp the zinc ingot stack.

[0007] Furthermore, a lifting lug is fixedly provided on the top of the crossbeam, the lifting lug is matched with a lifting hook, and the lifting hook is connected to a lifting device. The lifting device is used to transfer the sling.

[0008] Furthermore, the fixing arm is in a broken line shape and is symmetrical along the center line of the crossbeam, so that the two ends of the fixing arm are evenly stressed.

[0009] Furthermore, the plurality of fixed arms are fixedly connected via a pin shaft, and the clamping arm is rotatably sleeved on the pin shaft. One end of the clamping arm can rotate relative to the fixed arm.

[0010] Furthermore, a set of slings is provided at each end of the crossbeam, and the distance between the two sets of slings is less than the length of the zinc ingot stack, so as to make the clamping more stable.

[0011] Furthermore, when the upper portions of the two clamping arms connected to the same fixed arm are crossed and the lower portions are parallel, the distance between the lower portions of the two clamping arms is equal to twice the width of the zinc ingot stack. In this case, two zinc ingot stacks can be transferred at a time.

[0012] Furthermore, the connecting member is in the shape of an elongated strip and is arranged parallel to the crossbeam. The connecting member can limit the maximum and minimum opening angles of the clamping arm.

[0013] Through the above technical solution, the beneficial effects of the utility model are:

[0014] The fixed arm of the utility model is hinged to the clamping arm through a pin shaft, and multiple groups of clamping arms are connected together by connecting parts. The lifting equipment lifts the fixed arm through the hook, and the clamping arm automatically clamps the zinc ingot stack under the action of gravity. In the process of transferring the zinc ingot stacks, the two zinc ingot stacks remain stable and will not squeeze each other, so that the zinc ingot stacks are kept neat during the process of lifting them from the production line to the storage area, and the overall beauty of the zinc ingot stacks is improved.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 3 As shown, this embodiment provides a zinc ingot stack transfer sling, comprising a crossbeam 1, on which a plurality of groups of slings are arranged in parallel along the length direction thereof. In this embodiment, a group of slings is arranged at each end of the crossbeam 1, and a total of two groups of slings are arranged in this embodiment. A lifting lug 4 is fixedly provided on the top of the crossbeam 1, and the lifting lug 4 matches a hook, and the hook is connected to a lifting device. During the zinc ingot production process, individual zinc ingots are stacked and bundled into zinc ingot stacks 5 on the stacking production line. The zinc ingot stack transfer sling described in this embodiment transfers the zinc ingot stack 5 from the stacking production line to the zinc ingot storage area.

[0021] The sling includes a fixed arm 2 connected to the beam 1. The fixed arm 2 is symmetrical along the centerline of the beam 1. The top of the fixed arm 2 is fixedly connected to the beam 1, and the two ends of the fixed arm 2 are pivotally connected to the clamping arms 3. Specifically, the fixed arm 2 is symmetrically provided with circular through-holes at both ends, into which pins 22 are inserted.

[0022] Each of the two ends of the fixed arm 2 is rotatably connected to a clamping arm 3. As an embodiment, the multiple fixed arms 2 are fixedly connected by a pin 22, and the clamping arm 3 is rotatably sleeved on the pin 22. Buckles are provided on both sides of the clamping arm 3 to prevent the clamping arm 3 from axial displacement.

[0023] The upper part of the clamping arm 3 is inclined and the lower part is L-shaped. The two clamping arms 3 connected to each fixed arm 2 cross each other and are symmetrically arranged along the center line of the beam 1. The clamping arm 3 is used to clamp the zinc ingot stack 5. When the lifting equipment drives the sling to move downward, the two clamping arms 3 are manually opened and placed on both sides of the zinc ingot stack 5. When the lifting equipment drives the sling to move upward, the L-shaped bracket at the bottom of the clamping arm 3 automatically supports the zinc ingot stack 5. In the process of the zinc ingot stack 5 rising, the lower part of the clamping arm 3 is subjected to the downward pressure of the zinc ingot stack 5, driving the two clamping arms 3 to rotate in opposite directions, so that the two clamping arms 3 are automatically clamped.

[0024] Multiple clamping arms 3 arranged in parallel along the length of the crossbeam 1 and on the same side are fixedly connected by a connector 21. On the one hand, multiple groups of clamping arms 3 along the length of the zinc ingot stack 5 work together to provide more stable clamping. On the other hand, the maximum and minimum opening positions of the clamping arms 3 are limited to prevent the two clamping arms 3 connected to the same fixed arm 2 from completely separating. Specifically, the connector 21 is long and parallel to the crossbeam 1. The connector 21 is arranged at the intersection of the upper and lower portions of the clamping arms 3, that is, the end face of the connector 21 is fixedly connected to the top of the L-shaped lower portion of the clamping arm 3.

[0025] To prevent the two zinc ingot stacks 5 from being squeezed during transport, the distance between the two sets of slings is less than the length of the zinc ingot stack 5. Specifically, the distance between two adjacent clamping arms 3 on the same side is less than the length of the zinc ingot stack 5. When the two clamping arms 3 connected to the same fixed arm 2 have their upper portions intersecting and their lower portions parallel, the distance between the lower portions of the two clamping arms 3 is equal to twice the width of the zinc ingot stack 5. This allows two zinc ingot stacks 5 to be transferred at once, with even force applied between the two stacks, preventing them from squeezing each other. When transferred to the zinc ingot storage area, the two stacks 5 remain neatly aligned.

[0026] The working principle of this utility model:

[0027] During operation, the hook of the lifting equipment is connected to the lifting ear 4, and the lifting equipment is used to move the zinc ingot stack transfer sling to the upper part of the zinc ingot stack 5 to be transferred. The clamping arms 3 on both sides of the fixed arm 2 are manually opened, and the sling moves downward. When the zinc ingot stack 5 is located between the clamping arms 3, the clamping arms 3 are released to allow the clamping arms 3 to fall freely, and the lifting equipment is used to lift the sling. During the lifting process of the sling, the two clamping arms 3 rotate in opposite directions, thereby automatically clamping the zinc ingot stack 5. During the lifting process, the zinc ingot stack 5 is stably placed between the two clamping arms 3. When the utility model transfers two zinc ingot stacks 5 at a time, the two zinc ingot stacks 5 will not squeeze each other. When transferred to the zinc ingot storage area, the two zinc ingot stacks 5 remain neat.

[0028] When lowering the zinc ingot stack 5, the lifting equipment is controlled to move the sling downward. When the bottom of the clamping arm 3 touches the bottom, the two clamping arms 3 automatically open, thereby releasing the zinc ingot stack 5. During this process, the two zinc ingot stacks 5 are always kept neat.

[0029] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
