[0030] Referring to Figures 1-7 , the utility model provides a kind of hoisting device for tower crane technical solutions:

[0031] A hoisting device for tower crane, including top ring 1, top ring 1 is connected with several connecting ropes 2, the connecting rope 2 at the two ends of several connecting ropes 2 is connected with net bag 3 by anti-skid rope 4, and the connecting rope 2 between two net bags 3 is connected with anti-skid rope 4.

[0032] Wherein, referring to Figure 3 And Figure 4 , anti-skid rope 4 includes steel wire rope 41, and several rubber bumps 42 are arranged on steel wire rope 41, and end ring 44 is detachably fixedly connected at the two ends of steel wire rope 41.

[0033] Referring to Figure 1 And Figure 2 , the anti-skid rope 4 on the two net bags 3 is arranged at the opening end of net bag 3.

[0034] Referring to Figure 1As shown in one optional embodiment, four connecting ropes 2 are provided, and four anti-skid ropes 4 are provided.

[0035] Referring to Figure 1 As shown, the anti-skid ropes 4 between the two nets 3 are used to bundle the materials 5.

[0036] Referring to Figure 4 As shown, the end of the end ring 44 is fixedly connected with a connecting sleeve 43, one end of the connecting sleeve 43 is provided with an inner groove 48, the connecting sleeve 43 is vertically provided with an outer through hole 47, and the steel wire rope 41 is provided with an inner through hole 46 at both ends. The steel wire rope 41 and the connecting sleeve 43 are fixedly connected through the bolt 45.

[0037] It should be noted that the bolt 45 includes a nut matched therewith, during the installation of the end ring 44, referring to Figure 5 As shown, the bolt 45 is threadedly connected with the nut through the outer through hole 47 and the inner through hole 46, for fastening the connection of the steel wire rope 41 and the connecting sleeve 43.

[0038] It should be noted that the steel wire rope 41 is adhesively connected with the rubber block 42.

[0039] It should be noted that the woven material of the net 3 is a steel wire rope, the anti-skid rope 4 is fixedly connected with the net 3 through the mesh of the net 3, and the maximum outer diameter of the end ring 44 is greater than the diameter of the mesh of the net 3.

[0040] Referring to Figures 1-2 As shown, the net 3 is provided as a hollow sphere with a cut, and the diameter of the cut is less than the inner diameter of the hollow sphere.

[0041] Referring to Figure 6 As shown, both ends of the material 5 extend into the net 3, and the anti-skid rope 4 on the net 3 is in contact with the material 5, wherein it should be noted that the material 5 includes steel pipes, steel plates and other building materials.

[0042] The working principle of the device is explained by the use process of the device: when using the device, the two nets 3 are respectively sleeved at both ends of the material 5, and the material 5 is then bundled by the anti-skid rope 4, and the specific bundling process is as follows: by rotating the nut on the bolt 45, the bolt 45 is removed from the steel wire rope 41 and the connecting sleeve 43, so that the connecting sleeve 43 located below the anti-skid rope 4 is removed, the steel wire rope 41 is wound around the material 5, and finally passes through the end ring 44 located above the anti-skid rope 4 and winds several turns, and then the connecting sleeve 43 is installed, the bolt 45 passes through the outer through hole 47 and the inner through hole 46, and the nut is screwed into the bolt 45, thereby fixing the connecting sleeve 43 on the steel wire rope 41, and it needs to be pointed out that since the steel wire rope 41 is wound several turns on the end ring 44 located above the anti-skid rope 4, the inner diameter of the end ring 44 is reduced, thereby the connecting sleeve 43 reinstalled at the end of the steel wire rope 41 cannot pass through the end ring 44 again, and the fixing of the steel wire rope 41 after winding the material 5 is successfully achieved.

[0043] After the above operation is completed, the tower crane in the prior art is used to hook the top ring 1 with the hook on the tower crane, so that the material 5 is lifted to the required position.

[0044] The device successfully realizes the fixation of the material 5 by the setting of the nets 3 and the anti-skid rope 4, which uses the nets 3 to cover both ends of the material 5 and the anti-skid rope 4 located between the two nets 3 to bundle the material 5, and avoids the overflow of the material 5 at the end, greatly improving the stability of the material 5 during hoisting.

[0045] The device uses the anti-skid property of the rubber bump 42 to improve the friction between the material 5 and the steel wire rope 41 when the steel wire rope 41 winds the material 5, further improves the stability of the material 5 during hoisting, and uses the flexible disassembly of the connecting sleeve 43 and the end ring 44, so that when the steel wire rope 41 passes through the end ring 44 located above the anti-skid rope 4 and winds several turns, the connecting sleeve 43 and the end ring 44 reinstalled at the end of the steel wire rope 41 cannot pass through again, quickly and reliably realizing the bundling of the material 5 by the anti-skid rope 4, which is convenient, efficient and suitable for popularization and use.
