[0027] Reference below Figure 1-Figure 3 A spreader 100 according to an embodiment of the present invention is described.

[0028] The sling 100 of the present application is specifically used in the scene of lowering steel cages in pile foundation construction in the field of bridge construction technology. Of course, the application of the sling 100 of the present application is not limited to this, and it can also be applied to other fields and other scenarios. The sling 100 of the present application is provided with a sliding member 20, which can slide on the connecting member 12 to adjust the position of the lifting assembly 30, thereby forming slings 100 of different diameters to lift steel cages of different diameters, thereby achieving the purpose of processing a sling 100 to lift steel cages of any diameter.

[0029] like Figure 1 As shown, according to the embodiment of the utility model, the lifting device 100 is used for lifting a steel cage, and the lifting device 100 comprises: a connecting frame 10, a sliding member 20, a lifting assembly 30 and a friction iron sheet 40. The connecting frame 10 comprises a ring body 11 and a connecting member 12 arranged inside the ring body 11 and arranged crosswise; the sliding member 20 is arranged on the connecting member 12, and the sliding member 20 can selectively slide along the connecting member 12; the lifting assembly 30 is connected to the sliding member 20, and the sliding member 20 slides along the connecting member 12 to adjust the position of the lifting assembly 30; the friction iron sheet 40 is detachably mounted on the connecting member 12, and the friction iron sheet 40 is suitable for locking the position of the sliding member 20.

[0030] Specifically, if Figure 1 and Figure 2As shown, the connecting frame 10 of the sling 100 is provided with a sliding member 20 that can adjust the diameter of the sling 100 and a hoisting assembly 30 for hoisting a steel cage. The connecting frame 10 has a hollow ring body 11, and a plurality of connecting members 12 are arranged in the center of the ring body 11. The plurality of connecting members 12 are arranged crosswise, and the ends of the plurality of connecting members 12 are connected to the inner ring of the ring body 11, wherein the ring body 11 can be a circular ring, or a rectangular ring, or a ring of other shapes; illustratively, there can be two connecting members 12, and the two connecting members 12 are arranged crosswise, or there can be more connecting members 12, and the centers of the plurality of connecting members 12 intersect. The connecting frame 10 has a first face 13 and a second face that are arranged opposite to each other, the first face 13 is opposite to the steel cage, and the second face is opposite to the hoisting equipment, and the hoisting assemblies 30 are respectively installed on the first face 13 and the second face of the connecting frame 10, so that the hoisting equipment can hoist the sling 100, and the hoist 100 can hoist the steel cage.

[0031] It should be noted that a slide rail is formed on the connecting member 12, and the sliding member 20 can slide along the connecting member 12. The hanging assembly 30 disposed on the first surface 13 is connected to the sliding member 20. By sliding the sliding member 20, the hanging assembly 30 can slide freely on the connecting frame 10, thereby adjusting the diameter of the hanging device 100. Figure 1 As shown, the friction iron sheet 40 is detachably connected to the connecting member 12, and there is a certain gap between the left and right sides of the slide rail formed on the connecting member 12 and the sliding member 20. When the sliding member 20 slides to the final position, the friction iron sheet 40 is inserted into the gap on the left and right sides of the connecting member 12. The surface of the friction iron sheet 40 is provided with friction material, so that the static friction force of the friction iron sheet 40 can be used to limit the sliding of the sliding member 20, so as to limit the position of the sliding member 20 and prevent the sliding member 20 from moving with it during the movement of the sling 100.

[0032] According to the sling 100 of the embodiment of the utility model, its structure is simpler, and its use is more convenient and the operation is simpler and more convenient. By arranging a sliding member 20 that can slide along the connecting frame 10, it is convenient to adjust the position of the lifting assembly 30, thereby forming slings 100 of different diameters to lift steel cages of different diameters, thereby achieving the purpose of processing one sling 100 to lift steel cages of any diameter, thereby improving the versatility of the sling 100, eliminating the need for frequent replacement of the sling 100, saving time, and improving construction efficiency. By arranging the friction iron sheet 40, the position of the sliding member 20 can be locked by utilizing its static friction force, and the limiting effect is better.

[0033] like Figure 1 and Figure 2As shown, in some embodiments, the connecting member 12 has a bottom plate 121 and a rotating plate 122, the bottom plate 121 is arranged to extend radially along the ring body 11, and the two ends of the bottom plate 121 are connected to the inner ring of the ring body 11. The rotating plate 122 is arranged on the left and right sides of the bottom plate 121, and the rotating plate 122 is hinged to the side of the bottom plate 121, and can be flipped relative to the bottom plate 121. When the rotating plate 122 is rotated to be perpendicular to the bottom plate 121 and facing the free side toward the first surface 13, the rotating plate 122 and the side plate define a slide rail, and the other side of the rotating plate 122 is slightly higher than the first surface 13 of the ring body 11, that is, the height of the rotating plate 122 is greater than the thickness of the ring body 11. This arrangement has a simple structure and is convenient for flipping the rotating plate 122, so that the connecting member 12 forms a slide rail for the sliding member 20 to move.

[0034] like Figure 1 and Figure 2 As shown, the other side of the rotating plate 122, i.e., the side of the rotating plate 122 away from the bottom plate 121, is provided with a first fastener 60, and the first side 13 of the ring body 11 is provided with a second fastener, the second fastener corresponds to the first fastener 60, and when the rotating plate 122 is rotated to a position perpendicular to the bottom plate 121, the first fastener 60 and the second fastener are engaged. After adjusting the position of the sliding member 20, the first fastener 60 and the second fastener are unfastened, the rotating plate 122 is turned over, and the friction iron sheet 40 is respectively inserted into the left and right sides of the plurality of connecting members 12, and then the rotating plate 122 is turned over to a position perpendicular to the bottom plate 121, and the first fastener 60 and the second fastener are engaged to fix the position of the module iron sheet and lock the position of the sliding member 20 to prevent the sliding member 20 from sliding when the sling 100 moves. If it is necessary to readjust the position of the sliding member 20, unfasten the first fastener 60 and the second fastener to open the rotating plates 122 on the left and right sides of the base plate 121, and then take out the friction iron sheet 40, and then rotate the rotating plate 122 again to a position perpendicular to the base plate 121, and re-fasten the first fastener 60 and the second fastener to fix the position of the rotating plate 122 so that it remains perpendicular to the base plate 121 to form a slide rail, so that the position of the sliding member 20 can be moved to adjust the diameter of the sling 100.

[0035] In this way, by setting the first fastener 60 and the second fastener, the position of the rotating plate 122 can be fixed when the rotating plate 122 is rotated to a position perpendicular to the base plate 121, so that the rotating plate 122 and the base plate 121 form a slide rail. When it is necessary to disassemble the friction iron sheet 40, the state of the rotating plate 122 can be changed by controlling the first fastener 60 and the second fastener, thereby improving convenience.

[0036] In some embodiments, Figure 1-Figure 3As shown, the hoisting assembly 30 has a first lifting lug 31 and a second lifting lug 32, the first lifting lug 31 is connected to the sliding member 20, and the second lifting lug 32 is connected to the second surface of the ring body 11. Exemplarily, the sling 100 has two connecting members 12, the two connecting members 12 are cross-arranged, and four slide rails are formed from the cross position to the end of the connecting member 12, and a sliding member 20 is installed on each slide rail. There are four first lifting lugs 31, which are respectively connected to the four sliding members 20. Four second lifting lugs 32 are arranged on the second surface of the ring body 11, and the adjacent second lifting lugs 32 are spaced 90° apart. The first lifting lug 31 is respectively connected to the sliding member 20 and the steel cage, and the second lifting lug 32 is respectively connected to the ring body 11 and the hoisting equipment. In this way, the hoisting equipment can lift the steel cage through the sling 100, and the lifting is more convenient.

[0037] In some embodiments, the sling 100 further includes: a drive system 50, which is suitable for driving the sliding member 20 to reciprocate along the connecting member 12. The drive system 50 is arranged at the intersection of multiple connecting members 12, and the drive system 50 includes: a drive motor, a transmission gear set, a take-up roller and a traction rope. The drive motor is connected to the transmission gear set by power, and the transmission gear set is used to drive the take-up roller to move. One end of the traction rope is hinged to the connecting member 12, and the other end of the traction rope is fixed to the sliding member 20. In this embodiment, the transmission gear set is composed of a plurality of transmission gears meshing with each other, the drive motor is connected to the transmission gear installed at the power input end of the transmission gear set, and the take-up roller is connected to the transmission gear installed at the power output end of the traditional gear set. When working, the drive motor drives the take-up roller to rotate, and then drives the sliding member 20 to slide along the slide rail through the traction rope. In this way, the position of the sliding member 20 can be adjusted by starting the drive system 50, which saves manpower and facilitates the binding position of the first lifting ear 31 corresponding to the steel cage.
