[0006] Preferably, the clamping mechanism includes: a bidirectional screw rotatably mounted on the inner walls on both sides of the shell, both ends of the bidirectional screw extending to the outside of the shell; two sliders threadedly mounted on the bidirectional screw, both sliders being slidably connected to the inner walls of the shell; and two clamping blocks respectively welded to the two sliders.

[0007] Preferably, a plurality of steel wire ropes are disposed outside the two telescopic tubes, spring buckles are fixedly installed at both ends of the plurality of steel wire ropes, a fixing ring is disposed on the plurality of spring buckles, and the plurality of fixing rings are fixedly connected to the two limit rings and the two round tubes respectively.

[0008] Preferably, arc-shaped grooves are provided on the sides of the two clamping blocks that are close to each other, and anti-slip pads are fixedly installed on the inner walls of the two arc-shaped grooves.

[0009] Preferably, rotating rods are fixedly mounted on both ends of the bidirectional screw, and two protective sleeves are fixedly mounted on the two rotating rods.

[0010] Preferably, a plurality of anti-slip sheets are fixedly mounted on the two cover bodies, and the plurality of anti-slip sheets are all arranged in a rectangular shape.

[0011] Preferably, the two brackets are both configured as I-shaped, and the two brackets are both made of stainless steel.

[0012] Compared with the related art, the anti-falling steel bar hoisting device provided by the utility model has the following beneficial effects:

[0013] Compared with the prior art, the anti-falling steel bar lifting device provided by the present invention can support the steel bars to be lifted through two limit rings, and can clamp and fix the steel bars through the clamping mechanism, so that the steel bars can maintain good stability during the lifting process.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model provides a steel bar hoisting device to prevent falling, such as Figure 1-4 As shown, the anti-falling steel bar lifting device includes: a lifting ring 1 connected to a crane, on which a plurality of lifting ropes 2 are fixedly installed, and on which a same support plate 3 is fixedly installed; a shell 4 fixedly installed at the bottom of the support plate 3; two brackets 5 welded at the bottom of the support plate 3, and limit rings 6 are welded on both of the brackets 5; two telescopic tubes 7 fixedly installed on the two limit rings 6, and a round tube 8 is fixedly installed at one end of the two telescopic tubes 7 away from each other, and a cover body 9 for blocking the steel bars is threadedly installed on the two round tubes 8; and a clamping mechanism assembled on the shell 4 for fixing the steel bars.

[0022] After the two ends of the steel bar are lifted, the two ends of the steel bar can be fixed by the two telescopic tubes 7 and the two circular tubes 8.

[0023] In a further preferred embodiment of the utility model, the clamping mechanism includes: a bidirectional screw 10 rotatably mounted on the inner walls on both sides of the shell 4, both ends of the bidirectional screw 10 extending to the outside of the shell 4; two sliders 11 threadedly mounted on the bidirectional screw 10, both sliders 11 are slidably connected to the inner wall of the shell 4; and two clamping blocks 12 respectively welded on the two sliders 11.

[0024] In this embodiment, the clamping mechanism is used to fix the steel bars. When in use, the bidirectional screw 10 is rotated, and the bidirectional screw 10 will drive the two sliders 11 to approach each other, and the two sliders 11 will drive the two clamping blocks 12 to approach each other, so that the steel bars that need to be hoisted can be clamped and fixed, so that the steel bars can maintain good stability during the hoisting process.

[0025] In a further preferred embodiment of the utility model, a plurality of steel wire ropes 15 are provided on the outside of the two telescopic tubes 7, spring buckles 14 are fixedly installed at both ends of the plurality of steel wire ropes 15, and a fixing ring 13 is provided on the plurality of spring buckles 14, and the plurality of fixing rings 13 are fixedly connected to the two limiting rings 6 and the two circular tubes 8 respectively.

[0026] In this embodiment, by using a plurality of steel wire ropes 15, a plurality of spring buckles 14 and a plurality of fixing rings 13 in coordination, it is possible to shorten the distance between the limiting ring 6 and the round tube 8 when the device is hoisting some shorter steel bars, thereby preventing the telescopic tube 7 from automatically expanding. When it is necessary to replace a longer or shorter steel wire rope 15, it is sufficient to remove the spring buckle 14 from the fixing ring 13.

[0027] In a further preferred embodiment of the present invention, arc-shaped grooves are formed on the sides of the two clamping blocks 12 that are close to each other, and anti-slip pads 16 are fixedly installed on the inner walls of the two arc-shaped grooves.

[0028] In this embodiment, the use of two anti-slip pads 16 can effectively increase the friction between the two clamping blocks 12 and the steel bars, so that the two clamping blocks 12 can clamp and fix the steel bars more effectively.

[0029] In a further preferred embodiment of the present invention, rotating rods are fixedly installed at both ends of the bidirectional screw rod 10, and two protective sleeves are fixedly mounted on the two rotating rods.

[0030] In this embodiment, two rotating rods can facilitate workers to rotate the bidirectional screw 10, and the use of two protective sleeves can reduce the hardness of the surfaces of the two rotating rods, thereby improving the comfort of operation.

[0031] In a further preferred embodiment of the utility model, a plurality of anti-slip sheets are fixedly mounted on the two cover bodies 9, and the plurality of anti-slip sheets are all arranged in a rectangular shape.

[0032] In this embodiment, by using a plurality of anti-slip sheets, the friction between the cover body 9 and the worker's hand can be increased, thereby preventing the worker from slipping when rotating the cover body 9.

[0033] In a further preferred embodiment of the present invention, the two brackets 5 are both configured as I-shaped, and the two brackets 5 are both made of stainless steel.

[0034] In this embodiment, the bracket 5 made of stainless steel can effectively resist corrosion factors (such as moisture, salt, acid and alkali, etc.) in the external environment, extending the service life of the bracket 5. The stainless steel material also has good anti-oxidation performance, which can keep the bracket 5 beautiful and neat.

[0035] In summary, compared with the relevant technology, the present solution can support the steel bars that need to be hoisted through two limit rings 6, and can clamp and fix the steel bars through the clamping mechanism, so that the steel bars can maintain good stability during the hoisting process. Through the coordinated use of two telescopic tubes 7, two round tubes 8 and two covers 9, it is convenient for workers to use the device to fix and shield the two ends of the steel bars. In this way, when the crane uses the lifting device to hoist the steel bars, no matter how the steel bars shake and tilt, the steel bars will not have the risk of slipping, which can effectively improve the safety of the steel bars during the hoisting process and have a good use effect. Since the two telescopic tubes 7 can be telescoped, the length of the two telescopic tubes 7 can be shortened to reduce the space occupied by the device when not in use. Through the coordinated use of multiple steel wire ropes 15, multiple spring buckles 14 and multiple fixing rings 13, when hoisting some shorter steel bars, it can be used to shorten the distance between the limit rings 6 and the round tubes 8 to prevent the telescopic tubes 7 from automatically unfolding.
