Description

Technical Field

[0001] The utility model belongs to the technical field of lifting belts, in particular to a non-slip and wear-resistant heavy-duty lifting belt. Background Art

[0002] Conventional lifting belts are generally made of high-strength polyester filaments, which have multiple advantages such as high strength, wear resistance, oxidation resistance, and UV resistance. At the same time, they are soft, non-conductive, and non-corrosive, and are widely used in various fields. There are many types of lifting belts, and conventional lifting belts are divided into four categories: annular core-through, annular flat, double-eye core-through, and double-eye flat.

[0003] At present, most lifting belts are of fixed length, which makes it difficult to adjust their length according to actual needs during use. When lifting smaller objects, the objects will shake severely during the lifting process due to the longer length of the lifting belt. When lifting larger objects, it is difficult to cover the entire object, which makes it inconvenient during use.

[0004] In summary, the utility model provides a non-slip and wear-resistant heavy-duty lifting belt to solve the above problems. Utility Model Content

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1-4 As shown, the utility model provides a non-slip and wear-resistant heavy-duty lifting belt, comprising two connecting boxes 1 and a lifting belt 2, and the two ends of the lifting belt 2 are respectively fixedly connected to the opposite sides of the two connecting boxes 1, and the opposite sides of the two connecting boxes 1 are also provided with mounting grooves 3, and a winding mechanism is installed inside the mounting groove 3, and an adjusting belt 4 is installed inside the mounting groove 3 through the winding mechanism, and the lifting belt 2 is wound by the winding mechanism, so as to control the length of the lifting belt 2 passing through the mounting groove 3, and the other end of the adjusting belt 4 is wound from the mounting groove 3. The lifting belt 2 passes through the installation groove 3, and a connecting frame 5 is provided at one end of the adjusting belt 4 passing through the installation groove 3. A roller 6 is installed on the inner side of the connecting frame 5 away from the end of the installation groove 3. The roller 6 is used for facilitating the lifting belt 2 to move on the inner side of the connecting frame 5 when the length of the lifting belt 2 is adjusted, and the middle part of the lifting belt 2 is S-shaped and passes through the inner sides of the two connecting frames 5. The length of the adjusting belt 4 is adjusted to control the length of the overlapping part in the middle of the lifting belt 2, thereby achieving the effect of adjusting the length of the lifting belt 2.

[0023] Among them, the winding mechanism includes two connecting sleeves 7 rotatably installed on the inner walls on both sides of the installation groove 3, the ends of the two connecting sleeves 7 that are far away from each other respectively pass through the two sides of the connecting box 1, and the ends that pass through are connected to a first knob 8, and the first knob 8 can drive the connecting sleeve 7 to rotate, and a winding shaft 9 is also rotatably installed on the inner side of the installation groove 3, and the end of the adjusting belt 4 located in the installation groove 3 is fixedly connected to the winding shaft 9. During the rotation of the winding shaft 9, the winding shaft 9 can wind the adjusting belt 4 around its surface, thereby realizing the winding of the adjusting belt 4 and achieving the effect of controlling the length of the adjusting belt 4. The two ends of the winding shaft 9 are respectively passed through the two sides of the connecting box 1 by the inner sides of the two connecting sleeves 7, and the two ends that pass through are respectively connected to a second knob 10, and the second knob 10 can drive the winding shaft 9 to rotate, thereby realizing the winding of the adjusting belt 4.

[0024] Among them, the surfaces of the two ends of the winding shaft 9 located in the installation groove 3 are fixedly provided with connecting blocks 11, and the two sides of the connecting blocks 11 that are away from each other are provided with fixing grooves 12. One end of the connecting sleeve 7 located in the installation groove 3 is located on the inner side of the fixing groove 12, and the inner wall of the fixing groove 12 is evenly provided with inner ratchets 13. The inner walls of both sides of the installation groove 3 are respectively provided with rotating shafts 14 in an array inside the two fixing grooves 12, and the surfaces of the rotating shafts 14 are rotatably installed with pawls 15. Through the arrangement of the inner ratchet 13 and the pawl 15, the winding shaft 9 can only rotate in one direction, so that the adjustment belt 4 wound on the surface of the winding shaft 9 will not loosen.

[0025] Among them, the surface of the rotating shaft 14 is also equipped with a torsion spring, and the two ends of the torsion spring are respectively connected to the pawl 15 and the inner wall of the mounting groove 3. Under the action of the torsion spring, the pawl 15 is against the surface of the inner ratchet 13, thereby limiting the rotation direction of the inner ratchet 13.

[0026] Among them, a plurality of pull ropes 16 are fixedly connected to the surface of one end of the connecting sleeve 7 located in the installation groove 3, and the other ends of the pull ropes 16 are respectively connected to the ends of each ratchet 15 located in the same fixed groove 12 away from the rotating shaft 14. As the connecting sleeve 7 rotates, the connecting sleeve 7 will reel in each pull rope 16, thereby pulling the ratchet 15 away from the inner ratchet 13 through the pull rope 16, so that the reel-up shaft 9 can release the adjustment belt 4 rolled up on its surface.

[0027] A connecting belt 17 is fixedly connected to one side of the connecting box 1 away from the lifting belt 2 , and a connecting hook 18 is connected to the other end of the connecting belt 17 . The connecting hook 18 is used to facilitate the lifting operation.

[0028] The connecting belt 17, the lifting belt 2 and the adjusting belt 4 are all woven from anti-skid and wear-resistant materials. Specifically, the anti-skid material is synthetic fiber.

[0029] Specific working principle:

[0030] During the use of the utility model, the two second knobs 10 in the utility model are rotated respectively, and the reel 9 is driven to rotate by the second knobs 10, so that the adjustment belt 4 is reeled, and the distance between the two connecting frames 5 is changed. When the distance between the two connecting frames 5 changes, since the lifting belt 2 passes through the inner sides of the two connecting frames 5 in an S shape, the length of the overlapping part in the middle of the lifting belt 2 will also change, thereby achieving the effect of adjusting the length of the lifting belt 2. By setting the inner ratchet 13 and the pawl 15 When the pawl 15 abuts against the inner ratchet 13, since the winding shaft 9 can only rotate in one direction, the winding belt wound onto the surface of the winding shaft 9 can be prevented from loosening. At the same time, when the length of the lifting belt 2 needs to be increased again, it is only necessary to rotate the first knob 8 in the utility model, and the first knob 8 drives the connecting sleeve 7 to rotate, and the connecting sleeve 7 winds up the pull rope 16. The pawl 15 is pulled apart from the inner ratchet 13 by the pull rope 16, so that the winding shaft 9 can release the adjusting belt 4 wound on its surface, thereby restoring the length of the lifting belt 2.
