Specific implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figure 1-6 , the present utility model provides a technical solution: a temporary fixing device for hoisting steel bars, including a fixed sleeve 1. One end outer surface of the fixed sleeve 1 is fixedly welded with a supporting flat steel plate 2, and the supporting flat steel plate 2 is square, and the four corners of the supporting flat steel plate 2 are chamfered. The two outer surfaces of the fixed sleeve 1 are fixedly installed with connecting hanging ears 3, and the connecting hanging ears 3 are symmetrically designed. A butt joint type rotating mechanism is arranged between the fixed sleeve 1 and the connecting hanging ears 3, and through the butt joint type rotating mechanism, the steel bars can be hoisted and transported to the construction use site.

[0031] Through the chamfer design of the supporting flat steel plate 2, the damage caused by impact can be effectively prevented. At the same time, due to the symmetrical design of the connecting hanging ears 3, the overturning caused by the balance problem when the steel bars are placed into the fixed sleeve 1 can be effectively prevented.

[0032] The butt joint type rotating mechanism includes: a fixing bolt 5. The outer surface of the fixing bolt 5 penetrates through the outer surface of the connecting hanging ear 3, and a hanging ring 6 is arranged on the outer surface of the connecting hanging ear 3. The outer surface of the hanging ring 6 is attached to the outer surface of the connecting hanging ear 3, and the outer surface of the connecting hanging ear 3 is attached to the outer surface of the fixing bolt 5. One end outer surface of the hanging ring 6 is penetrated by the fixing bolt 5, and the outer surface of the fixing bolt 5 is attached to the outer surface of the hanging ring 6. And the hanging ring 6 and one end of the fixing bolt 5 are threadedly connected. A steel cable 7 is arranged between the hanging ring 6 and the fixing bolt 5.

[0033] When it is necessary to lift the steel bars, the steel bars can be inserted into the inside of the fixed sleeve 1. Subsequently, the steel cable 7 is threaded through the hanging ring 6, and the hanging ring 6 is placed into the connecting hanging ear 3. Then, the fixing bolt 5 is inserted through the hanging ring 6 and the connecting hanging ear 3, and the fixing bolt 5 is screwed into the inside of the hanging ring 6 to fix the upper end of the steel bars. Then, the steel cable 7 can be hung on the hook and the steel bars can be lifted and transported to the construction site. This reduces the useless work of repeatedly bundling the steel bars, improves the transportation efficiency of the steel bars, and eliminates the risk of the steel bars falling due to loose bundling.

[0034] There is a threaded connecting steel bar 4 between the fixed sleeve 1 and the supporting flat steel plate 2, and the threaded connecting steel bar 4 and the supporting flat steel plate 2 are inclined. The threaded connecting steel bars 4 are respectively arranged at the four corners of the supporting flat steel plate 2.

[0035] Through the inclined design of the threaded connecting steel bar 4, the connection strength between the fixed sleeve 1 and the supporting flat steel plate 2 can be effectively improved, and the risk of the fixed sleeve 1 and the supporting flat steel plate 2 breaking and separating after lifting the steel bars can be reduced. Moreover, the gripping device can be facilitated through the threaded connecting steel bar 4. Through the mutual welding and fixing between the fixed sleeve 1, the supporting flat steel plate 2, the connecting hanging ear 3 and the threaded connecting steel bar 4, the fixing device can be quickly built by welding, with simple production and low cost.

[0036] The outer surface of the end of the supporting flat steel plate 2 away from the fixed sleeve 1 is threadedly installed with a pointed needle insertion foot 14, and a force - borrowing plane 15 is provided on the outer surfaces of both sides of the pointed needle insertion foot 14.

[0037] When the device is hoisted and erected on a soft ground, the pointed needle insertion foot 14 enables the device with the steel bars to be inserted into the ground, making the device more stable when erected. And after the pointed needle insertion foot 14 is worn, the pointed needle insertion foot 14 can be unscrewed and replaced through the force - borrowing plane 15.

[0038] The outer surface of the steel cable 7 is provided with a threading and tightening mechanism. Through the threading and tightening mechanism, the steel cables 7 can be fixed. The threading and tightening mechanism includes: a front buckling plate 8, the outer surface of the front buckling plate 8 is fitted with the steel cable 7, and the outer surface of the steel cable 7 is fitted with a rear buckling plate 9. The outer surface of the rear buckling plate 9 is penetrated and installed with an annular bolt 10, and the annular bolt 10 is fitted with the outer surface of the rear buckling plate 9. The annular bolt 10 penetrates the outer surface of the front buckling plate 8, and the front buckling plate 8 is fitted with the outer surface of the annular bolt 10. One end of the annular bolt 10 is threadedly installed with a fixing nut 11, and the outer surface of the fixing nut 11 is fitted with the outer surface of the front buckling plate 8.

[0039] When hoisting steel bars, it is necessary to adjust the heights of the front fastening plate 8 and the rear fastening plate 9 on the steel cable 7 according to the length of the steel bar. Pass the ring bolt 10 through the front fastening plate 8 and the rear fastening plate 9, and screw the fixing nut 11 into the ring bolt 10, then the front fastening plate 8 and the rear fastening plate 9 can clamp the steel cable 7 to fix the position of the ring bolt 10. When the steel bar is too long, the front fastening plate 8, the rear fastening plate 9, the ring bolt 10 and the fixing nut 11 can be added again to prevent the steel bar from deforming and bending due to excessive length and causing it to fall.

[0040] A connecting fastening handle frame 12 is inserted between the rear fastening plate 9 and the ring bolt 10, and the connecting fastening handle frame 12 is engaged with the ring bolt 10. One end of the connecting fastening handle frame 12 is fixedly installed with a bundling cable 13, and the length of the bundling cable 13 can be folded in half and engaged with one end of the connecting fastening handle frame 12.

[0041] After inserting the steel bar into the fixed sleeve 1, the bundling cable 13 can be straightened and wound around the steel bar once, then the bundling cable 13 is wound around the other steel cable 7 and wound around the steel cable again. Then, the bundling cable 13 is put into the connecting fastening handle frame 12, and the steel cable 7 can be pulled. By the hoisting device and the steel bar, the steel cable 7 is straightened and drives the bundling cable 13 to tighten and fix the steel cable.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
