Description

Technical Field

[0001] This utility model relates to the field of lifting slings technology, and more specifically, to a rotatable lifting sling. Background Technology

[0002] Lifting slings are tools used in lifting operations to connect cranes to the loads being lifted. They include wire rope slings, chain slings, and straps, as well as connecting components such as hooks and shackles. They transmit traction force, enabling the lifting and movement of heavy objects. Widely used in construction, logistics, and other fields, they must meet safety standards and undergo regular inspection and maintenance to ensure operational safety.

[0003] Publication No. (CN222475879U) discloses a rotatable lifting sling, including a rotating disc, a mounting shaft located in the middle of the rotating disc, and a seat hook located below the bottom of the rotating disc. The mounting shaft includes: a support plate at the bottom end of the mounting shaft, and a positioning plate located above the rotating disc on the outside of the mounting shaft; through holes on both sides inside the positioning plate; fixing plates on both sides of the top of the positioning plate, with fixing rods at the four corners of the bottom of the two fixing plates; and a hydraulic cylinder on the top of the fixing plates. This utility model uses rolling grooves and ball bearings to make the rotating disc rotate with the support plate and positioning plate, making the rotation of the rotating disc more stable. The four sets of hooks allow for stable lifting of goods, and the hydraulic cylinder, clamping block, and brake pads can stop the rotating disc from rotating, thus stopping the rotation of the rotating disc and allowing for stable lifting of goods, improving the performance of the sling.

[0004] However, this type of rotatable lifting sling has the following drawbacks: Although it can achieve a rotation effect and stop the rotating disc by braking, the cargo is always suspended in the air. During the rotation and stopping process, because the cargo is suspended, it will rotate on its own due to inertia. At the same time, the chain will also rotate, causing the chain to become entangled, which greatly increases the safety hazard, reduces the service life of the chain, and increases the cost. It cannot reduce the inertia caused by rotation on the cargo and thus prevent the chain from becoming entangled, and it cannot lock the chain according to its length. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rotatable lifting sling to solve the problem that the prior art cannot reduce the inertia caused by rotation on the cargo, which leads to chain entanglement, while satisfying the rotation requirement.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rotatable lifting sling, comprising...

[0007] A connecting plate is rotatably connected to its exterior. A fixing sleeve is fixedly connected to the end of the rotating plate away from the connecting plate. A connecting post is slidably connected to the inner wall of the fixing sleeve. A locking plate is fixedly connected to the end of the connecting post away from the fixing sleeve. An elastic element three is fixedly connected to the inner wall of the fixing sleeve. A clamping plate is slidably connected to the inner wall of the connecting post. An S-shaped elastic element is fixedly connected to the outside of the clamping plate. Multiple pressure rings are slidably connected to the inner wall of the locking plate. An elastic element one is fixedly connected to the outside of each of the multiple pressure rings.

[0008] The pressure ring is fixedly connected to the outside of the connecting ring, the inner wall of the locking plate has multiple through holes, the inner wall of the locking plate has a groove, and the inner wall of the connecting post is slidably connected to a button.

One end of the transmission bar is in contact with the outside of the button. An inclined groove is formed on the inner wall of the card plate, and multiple card slots are formed on the inner wall of the fixing sleeve.

[0010] The end of the elastic element away from the fixed sleeve is fixedly connected to the outside of the connecting column, and the end of the clamping plate away from the S-shaped elastic element is clamped to the inner wall of the fixed sleeve.

[0011] The end of the S-shaped elastic element away from the card plate is fixedly connected to the inner wall of the connecting post, and the outer side of the elastic element is in contact with the inner wall of the locking plate.

Detailed Implementation

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a rotatable lifting sling, including a connecting plate 1, a rotating plate 2 rotatably connected to the outside of the connecting plate 1, a fixed sleeve 3 fixedly connected to the end of the rotating plate 2 away from the connecting plate 1, a connecting column 4 slidably connected to the inner wall of the fixed sleeve 3, a locking plate 5 fixedly connected to the end of the connecting column 4 away from the fixed sleeve 3, an elastic element 18 fixedly connected to the inner wall of the fixed sleeve 3, a clamping plate 11 slidably connected to the inner wall of the connecting column 4, an S-shaped elastic element 12 fixedly connected to the outside of the clamping plate 11, a plurality of pressure rings 6 slidably connected to the inner wall of the locking plate 5, and an elastic element 8 fixedly connected to the outside of each of the plurality of pressure rings 6, an elastic element 18 fixedly connected to the outside of the connecting column 4 at the end of the elastic element 18 away from the fixed sleeve 3, a clamping plate 11 clamping to the inner wall of the fixed sleeve 3 at the end of the clamping plate 11 away from the clamping plate 11, a fixed connection to the inner wall of the connecting column 4 at the end of the S-shaped elastic element 12, and the outside of the elastic element 18 contacting the inner wall of the locking plate 5.

[0027] After the rotating plate 2 rotates the goods, the goods will not stop due to inertia and will drive the chain to rotate, which greatly increases the safety hazard. Before this, the chain can be fixed by the pressure ring 6 and the elastic element 8 in the locking plate 5 to prevent the chain from getting tangled. At the same time, the locking plate 11 and the elastic element 18 in the connecting column 4 can adjust the locking plate 5 according to the length of the chain to meet the needs of different users.

[0028] Example 2: Based on Example 1, in order to facilitate the movement of the pressure ring 6, a connecting ring 7 is fixedly connected to the outside of the pressure ring 6, multiple through holes 9 are opened on the inner wall of the locking plate 5, a groove 10 is opened on the inner wall of the locking plate 5, a button 15 is slidably connected to the inner wall of the connecting post 4, the outside of the connecting ring 7 is slidably connected to the outside of the locking plate 5, and the outside of the pressure ring 6 is slidably connected to the inner wall of the groove 10.

[0029] When preparing to lift the goods, the sliding connecting ring 7 causes the pressure ring 6 to squeeze the elastic element 8, and the elastic element 8 releases space to satisfy the movement space of the pressure ring 6. This causes the pressure ring 6 to be misaligned with the through hole 9, so that the chain can be placed inside the through hole 9. This prevents the goods from causing the chain to rotate due to inertia during subsequent rotation, and also avoids chain entanglement, extending the chain's service life.

[0030] Example 3: Based on Example 2, in order to facilitate the movement of the card plate 11, a transmission bar 13 is slidably connected to the inner wall of the connecting column 4, a top plate 16 is connected to the outside of the transmission bar 13, and an elastic element 2 14 is fixedly connected to the outside of the top plate 16. One end of the transmission bar 13 is in contact with the outside of the button 15. A sloping groove 17 is provided on the inner wall of the card plate 11, and multiple card slots 19 are provided on the inner wall of the fixing sleeve 3. The end of the elastic element 2 14 away from the top plate 16 is fixedly connected to the inner wall of the connecting column 4. The end of the transmission bar 13 away from the button 15 is slidably connected to the inner wall of the sloping groove 17. The outside of the top plate 16 is slidably connected to the inner wall of the connecting column 4. The end of the card plate 11 away from the connecting column 4 is engaged with the inner wall of the card slot 19.

[0031] Pressing button 15 causes the transmission bar 13 to be compressed. Since the contact surfaces of button 15, transmission bar 13, and the inclined groove 17 in the locking plate 11 are all inclined, pressing button 15 causes the transmission bar 13 to move the locking plate 11. Under the influence of the inclined groove 17, the locking plate 11 moves away from the inside of the locking groove 19 in the fixed sleeve 3 and is no longer locked. The elastic element 14 provides space for the movement of the transmission bar 13, and the S-shaped elastic element 12 provides the movement space for the locking plate 11 and can reset the locking plate 11. Therefore, when the locking plate 11 moves away from the inside of the locking groove 19, the connecting post 4 can be adjusted inside the fixed sleeve 3, which in turn moves the locking plate 5 up and down. This allows the user to adjust the locking plate 5 according to the length of the chain, satisfying the locking of chains of different lengths.

[0032] The working process of this utility model is as follows:

[0033] First, after the goods are lifted, the rotating plate 2 allows the goods to rotate. When rotation stops, the goods are suspended in the air, and due to inertia, the chain will rotate, causing it to become tangled. This greatly increases safety hazards and reduces the chain's lifespan. Therefore, when preparing to lift the goods, the sliding connecting ring 7 allows the pressure ring 6 to press against the elastic element 8. The elastic element 8 releases its space, allowing the pressure ring 6 to move freely. This causes a misalignment between the pressure ring 6 and the through hole 9, allowing the chain to be placed inside the through hole 9. This prevents the goods from rotating the chain due to inertia during subsequent rotation, avoids chain tangling, and extends the chain's lifespan. When the chain is too long, pressing the button 15 will compress the transmission bar 13. When the button 15 is pressed, the contact surfaces of the button 15, the transmission bar 13, and the inclined groove 17 in the locking plate 11 are all inclined slopes. Therefore, when the button 15 is pressed, the transmission bar 13 will move the locking plate 11 in a certain direction. Under the influence of the inclined groove 17, the locking plate 11 will leave the inside of the locking groove 19 in the fixed sleeve 3 and will no longer be locked. The elastic element 14 provides space for the movement of the transmission bar 13, and the S-shaped elastic element 12 satisfies the activity space of the locking plate 11 and can reset the locking plate 11. So when the locking plate 11 leaves the inside of the locking groove 19, the connecting post 4 can be adjusted inside the fixed sleeve 3, which acts on the locking plate 5 to move up and down. This realizes the adjustment of the locking plate 5, allowing the user to adjust the locking plate 5 according to the length of the chain, thus satisfying the locking of chains of different lengths.
