[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0026] like Figures 1-5 As shown, the steel cage hoist of this embodiment includes a suspension assembly 1, a hoist 2 and a sling assembly 3, wherein the hoist 2 includes parallel longitudinal beams 4, and multiple cross beams 5 welded and fixed across the longitudinal beams 4. The longitudinal beams 4 are arranged in pairs, and multiple pairs of lifting ears 7 are arranged and fixed along the length direction of the longitudinal beams 4. The lifting ears 7 are connected to the gantry crane 400 through the suspension assembly 1. Multiple gantry cranes 400 can be set up to translate the hoist 2 and the steel cage 100 it lifts to the trough body position.

[0027] Furthermore, each crossbeam 5 forms a lifting section along the vertical section of the trough body. From the cross section of the longitudinal beam 4, two lifting points 6 are set at the bottom of each crossbeam 5. The lifting points 6 are connected to the bottom of the steel cage 100 through the sling assembly 3. The crossbeam 5 is a retractable structure. When the sling 2 is lowered into the steel cage 100, the crossbeam 5 is in a horizontal state. The crossbeam 5 is extended to the left and right sides to pass through the holes on both sides of the steel bars, thereby forming a total of 4 lifting points at the two lifting points 6 and the two ends of the crossbeam 5. This prevents the steel cage 100 from being deformed due to uneven force during the lifting process. The crossbeam 5 is set as a retractable structure that can adapt to steel cages 100 of different spans. Furthermore, a folding sunshade 8 is set on the top of the crossbeam 5. When the sling 2 is located above the trough body or the upper part of the external formwork, the folding sunshade 8 is unfolded to provide shade and rain protection for the lower construction. When the steel cage 100 needs to be lifted, the folding sunshade 8 is folded up.

[0028] Preferably, the lifting point 6 is an M16 nut, which is welded and fixed to the bottom of the beam 5; and the lifting lug 7 is welded with section steel.

[0029] like Figure 1In the embodiment shown, a single sling 1 weighs about 1.2 tons, and the sling 2 consists of two longitudinal beams 4 and nine cross beams. The nine cross beams 5 correspond to nine lifting sections respectively. Each lifting section is provided with two upper lifting points 200 symmetrically arranged at both ends of the cross beam 5. A lifting point 6 and a sling assembly 3 are designed at the lower part of the cross beam 5 to connect the steel cage 100 to form two auxiliary lifting points.

[0030] Furthermore, the suspension assembly 1 includes a lifting rope 12 and a shackle 13. The shackle 13 is fixed to the longitudinal beam 4. The lower end of the lifting rope 12 is connected to the longitudinal beam 4 through the shackle 13. Two lifting ropes 12 are provided and are hung together on the same hook below the door crane 400. Preferably, the lifting rope 12 is a φ16 steel wire rope.

[0031] Furthermore, the retractable crossbeam 5 includes a first rectangular square tube 9 and two second rectangular square tubes 10 slidably connected to the two ends of the first rectangular square tube 9. The first rectangular square tube 9 and the second rectangular square tube 10 are provided with pin holes arranged at the same intervals. The pin holes and the matching pins 11 form locking parts. The position is fixed by inserting the pins 11 into the pin holes in the center of the two. The first rectangular square tube 9 and the second rectangular square tube 10 can be freely extended and retracted to adapt to steel cages 100 of different sizes. The ends of the second rectangular square tubes 10 pass through the holes of the steel cage 100 to form upper hanging points 200.

[0032] Furthermore, the foldable sun visor 8 is laid on the upper surface of the beam 5, which includes a plurality of hinged sun visor modules 81. The sun visor modules 81 are folded upward to form a cover. By setting a plurality of hinge points, the sun visor modules 81 can be curled and folded toward the center line position, and vice versa, they can be unfolded to provide sunshade and rain protection for construction.

[0033] Furthermore, the sling assembly 3 includes a sling 14, a rope clamp 15, and a turnbuckle 16. The bottom end of the sling assembly 3 forms the lower hanging point 300 of the steel cage. The ends of the sling 14 are respectively fixed to the hanging point 6 and the rope clamp 15. The rope clamp 15 is fixedly connected to the turnbuckle 16. The bottom of the turnbuckle 16 is hooked and fixed to the bottom steel bars of the steel cage 100, serving as two lower hanging points 300. Preferably, the turnbuckle 16 uses an M10 specification.

[0034] The use process of this steel cage hoist is as follows:

[0035] The worker installs the suspension assembly 1, hoists the lifting tool 2 from the outer mold support on the trough body, folds the folding sun visor 8, removes the bolt 11 to release the locking, shrinks the second rectangular square tube 10 into the first rectangular square tube 9 and installs the bolt 11 to fix and prevent sliding, lowers the suspension assembly 1 and the lifting tool 2 into the steel reinforcement cage 100 through the portal crane 400, then removes the bolt 11, extends the small square tube 10 into the hole of the steel reinforcement cage 100, installs the sling 14, the rope clamp 15 and the basket bolt 16, connects the lifting tool 2 and the steel reinforcement cage 100, then hoists and translates the steel reinforcement cage 100 to the position of the trough body, lowers it into the inner part of the outer mold of the trough body, removes the sling 14, the rope clamp 15 and the basket bolt 16, releases the two lower hoisting points 300, removes the bolt 11, shrinks the second rectangular square tube 10 into the first rectangular square tube 9, releases the two upper hoisting points 200, installs the bolt 11 to lock the first rectangular square tube 9 and the second rectangular square tube 10, uses the portal crane 400 to lift and translate the suspension assembly 1 and the lifting tool 2 to the outer mold support of the trough body, so as to complete a cycle of steel reinforcement cage 100 hoisting construction, and sequentially completes the steel reinforcement hoisting construction of the whole aqueduct.
