Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a detachable and replaceable sling structure. Background Art

[0002] With the improvement of production technology in the steel plant section, the utilization rate of equipment is continuously enhanced and the production output value is increased. The cranes used in the factory adjust the mechanical structure according to the on-site production process to meet the fast-paced production needs and reduce the unnecessary working steps of the crane. At present, many steel plants carry out high-frequency cross-operations of lifting tundishes and slag trays in the same span. Two cranes working in the same span cannot meet the on-site use conditions. When adding a hook to the gantry spreader beam for use, it is necessary to dismantle the part below the four-point lifting fork of the gantry spreader, which takes a long time to dismantle and requires a lot of manpower. At present, the time for disassembly and replacement of crane spreaders has become the focus of production efficiency.

[0003] Chinese patent publication number CN211338506U discloses a sling structure for hoisting bucket elevator chain plates, comprising a self-locking sling and a shackle, wherein the self-locking sling and the shackle are detachably connected. The self-locking sling comprises a fixedly connected chain link baffle and a self-locking hook plate, and the self-locking hook plate is provided with a limit hook. The utility model utilizes the self-locking sling and shackle to hoist the chain plates. The self-locking sling can limit the position of the chain plates and connecting sleeves, preventing the chain plates from sliding during the hoisting process, ensuring a stable and safe hoisting process. The shackle is easily connected to the self-locking sling and the steel rope, enabling rapid assembly with the chain plates or steel rope, which helps improve the efficiency of chain plate replacement.

[0004] However, the above disclosed solution has the following shortcomings: when in use, the above device connects the lifting equipment via the hook and the self-locking structure. In actual use, the above device cannot stably connect to equipment that does not have a top lifting ring. Utility Model Content

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-4 The utility model is described in further detail.

[0030] Example 1, as Figures 1-4 As shown, in order to solve the existing problems, in this embodiment, the utility model discloses a detachable and replaceable sling structure, including a base 1 and a rotating bracket 2 connected to the top thereof, the rotating bracket 2 is rotatably connected to a connecting plate 3, a roller bracket is provided on the top of the connecting plate 3, and the roller bracket is rotatably connected to a plurality of movable pulleys 4, the bottom of the base 1 is connected to a graphite lubricated sleeve 5, the graphite lubricated sleeve 5 is rotatably connected to a hook 6, the bottom of the base 1 is connected to a rotating plate 7, and the rotating plate 7 is connected to a lifting component 8.

[0031] The lifting component 8 includes a rotating connector 801 rotatably connected to the rotating plate 7 , the end of the rotating connector 801 away from the rotating plate 7 is rotatably connected to a rotating connecting rod 803 , and the end of the rotating connecting rod 803 away from the rotating connector 801 is rotatably connected to a rotating connecting plate 804 .

[0032] The top of the rotating connecting plate 804 is connected to a telescopic rod 802, and the top of the telescopic rod 802 is connected to the bottom of the rotating plate 7. The end of the rotating connecting rod 803 away from the rotating connecting member 801 is fixedly connected to a rotating transmission rod 805, and the other end of the rotating transmission rod 805 is rotatably connected to a supporting bracket 806, and a supporting member 807 is connected to the side of the supporting bracket 806, and an anti-slip layer is provided on the side of the supporting member 807.

[0033] The side of the rotating plate 7 is provided with a plurality of rotating grooves, the inner walls of which are rotatably connected to the rotating connector 801 , and the plurality of rotating connectors 801 are circumferentially distributed on the sides of the rotating plate 7 and the rotating connector plate 804 .

[0034] The specific working principle is: this device can achieve the effect of stable lifting connection of different types of equipment. Compared with traditional devices, this device adopts a combination of a hook 6 and a lifting component 8 to achieve a variety of lifting connection methods.

[0035] When this device is in use, by combining and connecting the equipment with the top lifting ring with the hook 6 of this device, the device can be easily docked and lifted. The rotating bracket 2 structure on the top of the base 1 can enable the base 1 to tilt and rotate within a certain rotation angle range during actual use.

[0036] When the tubular device needs to be hoisted and connected, the hoisting component 8 is extended into the tubular device to perform abutment connection.

[0037] When the hoisting component 8 is in a relaxed state, the supporting member 807 can freely extend and retract. By manually shrinking the supporting member 807 toward the center, the hoisting component 8 can enter the interior of the tubular equipment. During the upward hoisting process, the upward pulling force causes the rotating connecting member 801 to rotate downward, thereby causing the lever structure formed by the rotating connecting rod 803 and the rotating transmission rod 805 to rotate. Under the condition of upward pulling force, the supporting member 807 expands outward under the combination of the rotating connecting rod 803 and the rotating transmission rod 805, and then clings to the inner wall of the tubular equipment, thereby ensuring the hoisting stability of the device. When the hoisting is completed, moving the base 1 downward can cause the supporting member 807 to relax inward.

[0038] Example 2, as Figures 1-4 As shown, in order to solve the existing problems, in this embodiment, based on the same concept as the above-mentioned embodiment 1, the detachable and replaceable sling structure also includes: a rotating shaft is provided in the graphite lubricating sleeve 5, and there is a gap between the outer arc surface of the rotating shaft and the inner arc surface of the graphite lubricating sleeve 5, and the gap is filled with graphite powder.

[0039] Rotation blocking members are provided on both sides of the rotating bracket 2 , and the rotation blocking members are symmetrically distributed on both sides of the rotating bracket 2 . The rotating bracket contacts both sides of the bottom of the connecting plate 3 , and the outer end surface of the hook 6 is provided with a wear-resistant layer.

[0040] The specific working principle is: the graphite lubricating sleeve 5 of the device can reduce the rotational wear between the hook 6 and the bottom of the base 1 when the structure of the hook 6 rotates.

[0041] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
