Specific embodiments

[0019] In order to make the objectives, contents and advantages of the present invention clearer, the following further describes in detail the specific embodiments of the present invention with reference to the drawings and embodiments.

[0020] This embodiment provides a sling, and its overall structure is as Figure 1 shown, mainly including a mounting block 1, an H-shaped slide rail 2, a limiting block 3, a sliding block 4, a telescopic assembly 5, a steering assembly 6, a sling assembly 7 and a connection assembly 8. Among them, both ends of the mounting block 1 are fixedly connected with an H-shaped slide rail 2, the outer ends of the two H-shaped slide rails 2 are respectively fixedly connected with a limiting block 3, and the two H-shaped slide rails 2 are respectively slidably connected with a sliding block 4. Two telescopic assemblies 5 are respectively connected between the two sliding blocks 4 and the corresponding ends of the mounting block 1. The telescopic assembly 5 is used to drive the sliding block 4 to reciprocate on the surface of the H-shaped slide rail 2 to adjust the distance between the two sliding blocks 4. A steering assembly 6 is connected to the bottom of each sliding block 4, a sling assembly 7 is connected to the bottom of each steering assembly 6, and a connection assembly 8 is installed at the bottom of each sling assembly 7. The connection assembly 8 is used to connect the sling assembly 7 and the item to be lifted. The steering assembly 6 can drive the sling assembly 7 and the connection assembly 8 to turn.

[0021] As Figure 2 shown, the sling assembly 7 mainly includes a first connection block 701, a first sling 702, a second sling 703 and a second connection block 704. Among them, the first sling 702 and the second sling 703 are wound around each other, and the upper and lower ends are respectively connected to the first connection block 701 and the second connection block 704. By providing the mutually wound first sling 702 and second sling 703, the sling strength can be increased. Even if one of the slings breaks during work, the item to be lifted can still be safely placed on the ground by the other sling, improving the safety of the sling during work.

[0022] The steering assembly 6 mainly includes a rectangular groove 601, a limiting groove 602, a limiting piece 603 and a special-shaped block 604. Among them, the rectangular groove 601 is opened on the side wall of the sliding block 4, the limiting groove 602 is opened at the inner bottom of the rectangular groove 601, and the limiting piece 603 is movably clamped inside the limiting groove 602. The top of the special-shaped block 604 is inserted into the limiting groove 602 from the bottom of the sliding block 4 and is connected to the bottom of the limiting piece 603. The bottom of the special-shaped block 604 is connected to the top of the first connecting block 701. Through the arrangement of the limiting piece 603 and the limiting groove 602, the special-shaped block 604 can be rotated, so that the sling assembly 7 and the connecting assembly 8 can be driven to steer when needed, improving the applicability of the sling.

[0023] As Figure 3 shown, the connecting assembly 8 mainly includes a hook 801, a threaded block 802 and two threaded pins 803. Among them, the hook 801 is connected to the bottom of the threaded block 802, and the threaded block 802 is threadedly connected to the bottom of the second connecting block 704. The two threaded pins 803 are both threadedly connected inside the second connecting block 704, and the bottom ends of the two threaded pins 803 both extend to the bottom of the second connecting block 704. Through the arrangement of the hook 801 and the threaded pins 803, it is convenient for the user to select a suitable tool to connect with the item to be lifted according to actual use needs.

[0024] As Figure 4 shown, the telescopic assembly 5 mainly includes an installation groove 501 and a hydraulic cylinder 502. Among them, the two installation grooves 501 are respectively opened at both ends of the installation block 1, the fixed ends of the two hydraulic cylinders 502 are respectively arranged inside the two installation grooves 501, and the output end of each hydraulic cylinder 502 extends outside the installation groove 501 and is connected to the corresponding sliding block 4. Through the operation of the hydraulic cylinder 502, the sliding block 4 can be driven to slide reciprocally on the surface of the H-shaped slide rail 2, so as to adjust the distance between the two sliding blocks 4, enabling the sling to lift items of different lengths.

[0025] When using the sling of the present invention, first start two hydraulic cylinders 502 according to the length of the item to be lifted. The two hydraulic cylinders 502 push two sliding blocks 4, so that the two sliding blocks 4 can reciprocally slide on the surfaces of the two H-shaped slide rails 2 respectively, thereby adjusting the distance between the two sliding blocks 4 according to the length of the item to be lifted. After the adjustment is completed, according to the actual situation of the item to be lifted, drive the limiting piece 603 to rotate inside the limiting groove 602 through the special-shaped block 604, drive the second connecting block 704 to rotate with the first connecting block 701, so that the hook 801 can be steered according to the actual situation of the item to be lifted. According to the actual situation of the item to be lifted, the staff can choose to use the hook 801 or the threaded pin 803 to connect the item to be lifted by themselves. When the threaded pin 803 needs to be used, only need to rotate the hook 801 to drive the threaded block 802 to rotate and withdraw from the bottom of the second connecting block 704, and thread the threaded pin 803 into the interior of the item to be lifted to fix the second connecting block 704 and the item to be lifted.

[0026] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
