DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 - Figure 2, an embodiment provided by the present utility model: a convenient and lightweight hoisting protection device, including a suspension plate 1 that plays a role in fixing and supporting. There are two groups of suspension plates 1, which are symmetrically arranged left and right. A support rod 2 that plays a role in connecting and fixing is fixedly connected to the inner side of the suspension plate 1. A telescopic component for conveniently adjusting the distance between the suspension plates 1 is fixedly connected to the inner side of the support rod 2. Rotating rings 3 are rotatably connected to the upper and lower sides inside the suspension plate 1. There are two groups of rotating rings 3, which are symmetrically arranged on the upper and lower sides of the suspension plate 1. A suspension hole 4 for conveniently passing through the suspension steel rope is formed inside the rotating ring 3. Sliding sleeves 5 are respectively hinged to the left and right sides of the rotating ring 3. There are three sliding sleeves 5 on each side of the rotating ring 3, which are evenly distributed in a ring on the outer wall of the side of the rotating ring 3. A clamping component for conveniently fixing the suspension steel rope is slidably connected inside the sliding sleeve 5. The clamping component includes a clamping rod 6. The outer circumference of the clamping rod 6 is slidably connected inside the sliding sleeve 5. The sliding sleeve 5 restricts the clamping rod 6 to only slide along the inner wall of the sliding sleeve 5. The outer end of the clamping rod 6 is hinged to the outer wall of the side of the suspension plate 1. The clamping rod 6 can rotate around the hinge point between the clamping rod 6 and the suspension plate 1. A clamping wheel 7 for conveniently clamping the steel rope is hinged to the inner end of the clamping rod 6. A convex block 8 is fixedly connected to the top of the rotating ring 3. The convex block 8 is only arranged on the outer wall of the inner side of the rotating ring 3. A threaded block 9 is hinged to the inner side of the convex block 8. A threaded rod 10 is threadedly connected inside the threaded block 9. The outer circumference of the threaded rod 10 is rotatably connected to a fixed bracket 11. The outer side of the fixed bracket 11 is hinged to the outer wall of the side of the suspension plate 1. When the threaded rod 10 rotates, it drives the threaded block 9 to slide along the outer wall of the threaded rod 10. At this time, the fixed bracket 11 and the threaded block 9 will rotate simultaneously to ensure that the fixed bracket 11 and the threaded block 9 always remain relative, thereby avoiding movement interference.

[0031] Refer to Figure 1 and Figure 3, the telescopic component includes a rotating circular block 12, the outer side of the rotating circular block 12 is fixedly connected to the inner side of the support rod 2, multiple transverse grooves are arranged on the outer circumference of the rotating circular block 12 to increase the friction force and facilitate rotation. A bidirectional threaded column 13 is threadedly connected inside the rotating circular block 12. The bidirectional threaded column 13 is provided with two sets of symmetric threads with opposite spiral directions. Two rotating circular blocks 12 are respectively arranged on the two threads with opposite spiral directions and are guaranteed to be symmetric in position. The outer circumference of the bidirectional threaded column 13 is slidably connected inside the left and right support rods 2. Both ends of the bidirectional threaded column 13 are fixedly connected with retaining rings 14. A sliding column 15 is slidably connected inside the bidirectional threaded column 13. The sliding column 15 can rotate freely with the bidirectional threaded column 13. One set of prism blocks 16 are respectively fixedly connected to both ends of the sliding column 15. Circular sliding grooves 17 are opened inside the support rod 2. Prismatic grooves 18 are opened on the side inner wall of the circular sliding groove 17. There are six sets of prismatic grooves 18, and the six prismatic grooves 18 are adapted to the six edges of the prism blocks 16. The outer circumference of the retaining ring 14 is slidably connected inside the circular sliding groove 17 to limit the maximum telescopic amount of the bidirectional threaded column 13 and prevent the bidirectional threaded column 13 from detaching from the support rod 2. The outer circumference of the prism blocks 16 is slidably connected inside the prismatic grooves 18 to synchronize the rotation of the two support rods 2. When one support rod 2 rotates, the other support rod 2 rotates in the same direction. At this time, the two support rods 2 will move in opposite or relative directions along the bidirectional threaded column 13.

[0032] Working principle: When it is desired to quickly fix with the lifting rope, the lifting rope connected to the crane is inserted into the upper two sets of lifting holes 4, and the lifting rope connected to the object to be lifted is inserted into the lower two sets of lifting holes 4. Then rotate the threaded rod 10. The threaded rod 10 drives the threaded block 9 to move backward along the outer wall of the threaded rod 10. The threaded block 9 drives the convex block 8 to move backward. The convex block 8 drives the rotating ring 3 to rotate backward. The rotating ring 3 drives the two sliding sleeves 5 to rotate backward at the same time. The sliding sleeves 5 approach the hinge points between the clamping rods 6 and the lifting plate 1, causing the clamping rods 6 to slide inside the sliding sleeves 5. At the same time, the clamping rods 6 deflect inward, driving the clamping wheels 7 to deflect inward, so as to conveniently clamp the lifting rope and quickly fix it between the crane and the object to be lifted, and make the steel rope not easy to slide and relatively stable. When it is desired to conveniently adjust the distance between the lifting plates 1, hold the middle bidirectional threaded column 13 and then rotate one of the rotating circular blocks 12. The rotating circular block 12 drives the support rod 2 to rotate. The support rod 2 drives the prism block 16 to rotate through the prismatic groove 18. The prism block 16 drives the sliding column 15 to rotate. The sliding column 15 drives the prism block 16 on the other side to rotate. Thus, rotating one rotating circular block 12 can drive the other rotating circular block 12 to rotate together, and at the same time move in opposite or opposite directions along the bidirectional threaded column 13, so that the displacement amounts of the two support rods 2 on the bidirectional threaded column 13 are the same, always ensuring that the contact areas of both sides with the bidirectional threaded column 13 are consistent. Therefore, during hoisting, the bearing structures on both sides are ensured to be the same, so that the hoisting protection structure will not be damaged due to excessive force on one side, improving the durability.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
