Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, specifically to a steel reinforcement hoisting device for steel tower columns used in the construction of steel-concrete composite main towers of bridges. Background Technology

[0002] The steel-concrete composite structure of the main tower of a bridge fully utilizes the tensile strength of steel and the compressive strength of concrete, significantly improving the mechanical properties of the steel structure and enhancing its economic efficiency. Steel-concrete composite bridges hold an important position in bridge construction due to their economical overall stress distribution, rational utilization of the advantages of both steel and concrete, and ease of construction. However, steel-concrete composites present construction challenges. Positioning the bolts for anchoring the steel tower at the composite section is difficult, especially since the bridge tower uses 50mm diameter steel bars as main reinforcement. The weight and diameter of these bars cause positioning difficulties, leading to complex PBL (Positioning Bar Circular Reinforcement) installation procedures and high precision requirements for tower column installation. Currently, the installation and positioning of the reinforcement bars within the tower column are achieved by installing flanges inside the tower column, inserting the reinforcement bars into through-holes in the flanges, and then using shear studs and circumferential reinforcement bars to position and fix the bars within the tower column. Existing construction methods suffer from complex construction processes and low construction efficiency. Therefore, this application provides a steel bar hoisting device for steel tower columns used in the construction of steel-concrete composite main towers of bridges. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention proposes a steel reinforcement hoisting device for steel tower columns used in the construction of steel-concrete composite main towers of bridges, which has the advantages of convenient operation, reduced construction difficulty, and improved construction efficiency.

[0004] The technical solution of this invention is implemented as follows: A steel reinforcement hoisting device for steel tower columns used in the construction of steel-concrete composite bridge main towers, comprising: The positioning ring has a clamp on its outer side, and the positioning ring is fixed to the top of the steel tower column by the clamp. The positioning ring has multiple steel bar positioning holes. A guide ring is provided, which has guide holes that correspond one-to-one with the positioning holes of the reinforcing bars. A rope through hole is provided on the inner side of each guide hole. A first lifting rope is passed through the rope through hole. A lifting ring is connected to the top of the first lifting rope. A second lifting rope is provided between the lifting ring and the guide ring. A rotating arm, with its two ends rotatably connected to the sides of the positioning ring and the guide ring respectively, allows the rotating arm to switch between a state where the guide ring is directly above the positioning ring and a state where the guide ring is outside the steel tower column by rotating. A rebar clamp is provided corresponding to each of the aforementioned guide holes. The first lifting rope is fixed to one side of the rebar clamp. The rebar clamp includes a rebar sleeve and strip-shaped clamps symmetrically distributed on the rebar sleeve. The bottom end of each strip-shaped clamp is rotatably connected to the rebar sleeve and is provided with a torsion spring. When the strip-shaped clamping block is in the unfolded state, its top end is outside the circumference of the guide hole. When the strip-shaped clamping block is in the retracted state and clamps the reinforcing bar, the entire reinforcing bar clamp can pass through the guide hole. When the second lifting rope is in the taut state, the bottom end of the reinforcing bar clamped by the reinforcing bar clamp is located below the guide hole. When the guide ring is located directly above the positioning ring, the minimum distance between the two is greater than the length of the reinforcing bar clamp.

[0009] Furthermore, the reinforcing bar sleeve has a hollow columnar structure, and a first strip-shaped through groove is provided on the reinforcing bar sleeve corresponding to each of the strip-shaped clamps. The bottom end of the strip-shaped clamp is rotatably connected to the inner walls of both sides of the first strip-shaped through groove through an installation shaft, and the torsion spring is disposed between the installation shaft and the side wall of the first strip-shaped through groove. The rebar clamp also includes an outer sleeve fitted over the outside of the rebar sleeve. The outer sleeve includes a translational sleeve and a threaded sleeve arranged vertically. The bottom end of the translational sleeve is rotatably connected to the top end of the threaded sleeve. The translational sleeve has a second strip-shaped groove corresponding to each of the first strip-shaped grooves. When the strip-shaped clamp is in the unfolded state, its top end extends from the second strip-shaped groove to the outside of the translational sleeve. The inner side of the strip-shaped clamp is set as an arc-shaped surface adapted to the surface of the suspended rebar. The top width of the strip-shaped clamp is greater than its bottom width, so that when the inner side of the strip-shaped clamp is in a vertical state, its outer side is an inclined surface with the top end tilting outward. The upper part of the outer side of the strip-shaped clamp is located in the second strip-shaped groove. The upper part of the outer surface of the rebar sleeve is set as a smooth plane, and the lower part of the outer surface of the rebar sleeve is set as threadedly connected to the threaded sleeve. The conical structure at the top of the rebar sleeve is the top end of the translational sleeve.

[0010] Furthermore, the top wall of the second strip-shaped channel is an inclined surface with the inner end sloping downwards, and the inner side of the top of the strip-shaped clamping block is also an inclined surface with the inner end sloping downwards. When the inner side of the strip-shaped clamping block is held vertically on the surface of the reinforcing bar, the outer end of the inclined surface at the top of the strip-shaped clamping block is located outside the inner end of the inclined surface of the top wall of the second strip-shaped channel.

[0011] Furthermore, the outer sleeve also includes a rotating sleeve that is axially slidably connected to the bottom end of the threaded sleeve. The rotating sleeve is rotatably sleeved on the outside of the rebar sleeve, and both the rotating sleeve and the bottom end of the rebar sleeve are provided with a tapered structure. The inner diameter of the rebar sleeve is larger than the outer diameter of the rebar being suspended.

An upper top ring is fixedly provided on the top of the positioning ring, and when the guide ring is located directly above the positioning ring, the upper top ring is located directly below the lifting rod.

[0012] Furthermore, the diameter of the rope hole is larger than the outer diameter of the first suspension rope, and both the upper and lower ends of the rope hole are provided with chamfers. The inner wall of the rope hole is provided with a second side groove that communicates with the first side groove. A second side clamping block that slides in the second side groove is fixedly provided on the inner side of the first side clamping block. A second side clamping groove with an inner diameter similar to the outer diameter of the first suspension rope is provided on the side of the second side clamping block facing the center of the rope hole. Both the upper and lower ends of the groove of the second side clamping groove are provided with chamfers that are adapted to the rope hole. An upper connecting sleeve with both ends being tapered is fixedly provided at the end of the connecting plate away from the translation sleeve. The upper connecting sleeve is fixedly sleeved on the bottom end of the suspension rope. A lower connecting sleeve with both ends being tapered is fixedly provided at the end of the support plate away from the steel bar sleeve.

[0013] Furthermore, the bottom height of the tapered portion of the upper connecting sleeve is greater than the top height of the translation sleeve, and the top height of the tapered portion of the lower connecting sleeve is less than the bottom height of the reinforcing bar sleeve. A slot is provided on the inner side of the second side clamping block, into which a rod is inserted. A hole is provided on the guide ring for the rod to pass through. A rod spring is provided between the hole and the rod to provide elastic force for the rod to be inserted into the hole. The outer ends of the two rods corresponding to the same rope through-hole extend... An arc-shaped plate is connected to the inner cavity of the guide ring. An outer top plate is fixedly installed on both the upper and lower sides of the inner surface of the arc-shaped plate. Displacement grooves for the inward and outward displacement of the outer top plate are opened on both the upper and lower surfaces of the guide ring. The inner end of the displacement groove is connected to the rope hole. The top of the outer top plate extends into the rope hole. The top and bottom of the inner end of the outer top plate are chamfered. When the first suspension rope is located in the rope hole, the outer top plate is pushed outward by the first suspension rope, so that the insertion rod is located outside the slot.

[0014] The present invention has the following beneficial effects: In the process of constructing steel-concrete bridge towers, this invention greatly improves the construction efficiency of the steel towers. Compared with the existing technology that inserts steel bars one by one into the flange of the steel tower, this invention allows construction workers to directly clamp and fix the top of the steel bars on the ground using steel bar clamps, and then directly use a crane to insert the steel bars into the steel tower in one go and position them, which greatly improves construction efficiency and reduces construction difficulty.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1 to 3 As shown, the steel reinforcement hoisting equipment for steel tower columns used in the construction of steel-concrete composite bridge main towers provided by this invention includes a positioning ring 1, a guide ring 4, a guide hole 5, a rope threading hole 6, a first hoisting rope 7, a second hoisting rope 9, a swivel arm 10, and a steel reinforcement clamp 11. Please refer to [link / reference]. Figure 4 and Figure 5 As shown, a clamp 2 is fixedly connected to the outer side of the positioning ring 1. The positioning ring 1 is fixed to the top of the steel tower column by the clamp 2. Multiple rebar positioning holes 3 are provided on the positioning ring 1. Specifically, the clamp 2 includes a base plate, a sliding groove on the base plate, clamping plates slidably disposed within the sliding groove, and a bidirectional screw rod rotatably mounted on the upper surface of the base plate. The top ends of the two clamping plates are threadedly connected to the two bidirectional screw rods respectively. During operation, by placing the base plate on the top of the steel tower column and then rotating the bidirectional screw rod, the two clamping blocks on the clamp 2 clamp the top of the steel tower column from both the inside and outside, thereby fixing the positioning ring 1 to the top of the steel tower column. The rebar positioning holes 3 are used for the rebar to pass through and enter the interior of the steel tower column, simultaneously positioning the rebar.

[0018] Please see Figure 1 and Figure 2 As shown, guide holes 5 are formed on guide rings 4, and each guide hole 5 corresponds to a rebar positioning hole 3. Rope holes 6 are formed on the inner side of each guide hole 5, and each rope hole 6 corresponds to a guide hole 5. A first lifting rope 7 is threaded through the rope hole 6, and a lifting ring 8 is connected to the top of the first lifting rope 7. A second lifting rope 9 is provided between the lifting ring 8 and the guide ring 4. Specifically, both ends of the second lifting rope 9 are fixedly connected to the lifting ring 8 and the guide ring 4, respectively.

[0019] Please see Figure 1As shown, the two ends of the rotating arm 10 are rotatably connected to the sides of the positioning ring 1 and the guide ring 4, respectively. Specifically, a rotating arm 10 is connected between each side of the positioning ring 1 and the guide ring 4. The rotating arm 10 rotates around its connection point with the positioning ring 1, switching between a state where the guide ring 4 is directly above the positioning ring 1 and a state where the guide ring 4 is outside the steel tower column. More specifically, when the guide ring 4 is outside the steel tower column, the rotating arm 10 is supported on the top of the steel tower column. At this time, the guide ring 4 is stably supported on one side of the steel tower column by the positioning ring 1 through the rotating arm 10. When the guide ring 4 is directly above the positioning ring 1, the guide hole 5 is directly above the rebar positioning hole 3.

[0020] Each reinforcing bar clamp 11 is provided corresponding to each guide hole 5, and the bottom end of the first lifting rope 7 is fixed to one side of the reinforcing bar clamp 11. Specifically, the reinforcing bar clamp 11 is used to clamp one end of the reinforcing bar to be lifted. The first lifting rope 7 lifts the reinforcing bar clamp 11, and the reinforcing bar clamp 11 can lift the reinforcing bar. At the same time, after the reinforcing bar clamp 11 passes through the guide hole 5 from bottom to top, the reinforcing bar to be lifted also passes through the guide hole 5 and is limited by the guide hole 5, so that the reinforcing bar is limited by the guide hole 5.

[0021] Please see Figure 3 , Figures 10 to 13 As shown, the rebar sleeve 11 includes a rebar sleeve 11-1 and strip-shaped clamping blocks 11-2. The strip-shaped clamping blocks 11-2 are centrally symmetrically distributed on the rebar sleeve 11-1. The bottom end of the strip-shaped clamping blocks 11-2 is rotatably connected to the rebar sleeve 11-1 and is provided with a torsion spring. The torsion spring provides elastic force for the strip-shaped clamping blocks 11-2 to unfold. Wherein: When the strip clamp 11-2 is in the unfolded state, its top end is outside the circumference of the guide hole 5. In this state, as the first lifting rope 7 lifts the rebar sleeve 11 upwards, and the rebar sleeve 11 passes through the guide hole 5 from bottom to top, the top end of the strip clamp 11-2 will abut against the lower surface of the guide ring 4. At this time, the first lifting rope 7 can lift the guide ring 4 as a whole, thus having the function of raising the guide ring 4. When the strip clamp 11-2 is in the retracted state and clamps the rebar, the rebar sleeve 11 can pass through the guide hole 5 as a whole. In this state, as the first lifting rope 7 lifts the rebar sleeve 11 upwards, and the rebar sleeve 11 passes through the guide hole 5 from bottom to top, the rebar sleeve 11 will clamp the top end of the lifted rebar through the guide hole 5, so that the lifted rebar is limited by the guide hole 5.

[0022] When the second lifting rope 9 is taut, the bottom end of the rebar held by the rebar clamp 11 is below the guide hole 5. In this state, the lifting ring 8, through the first lifting rope 7 and the second lifting rope 9, has the function of lifting the guide ring 4 together with the rebar as a whole. When the guide ring 4 is directly above the positioning ring 1, the minimum distance between the guide ring 4 and the positioning ring 1 is greater than the length of the rebar clamp 11. In this state, after the rebar is positioned by passing through the rebar positioning hole 3 on the positioning ring 1, the rebar clamp 11 is located below the guide ring 4 when the rebar is released. Thus, after the rebar is released, the rebar clamp 11 unfolds using the strip clamp 11-2, and during the process of the rebar clamp 11 being lifted again by the first lifting rope 7, the strip clamp 11-2 supports the bottom of the guide ring 4, lifting the guide ring 4 and causing it to move away from the area directly above the positioning ring 1.

[0023] The rotating arm 10 includes a first arm 10-1 and a second arm 10-2. The included angle between the first arm 10-1 and the second arm 10-2 is an obtuse angle. The end of the first arm 10-1 away from the second arm 10-2 is rotatably connected to the middle of the side of the guide ring 4. The end of the second arm 10-2 away from the first arm 10-1 is rotatably connected to the side of the positioning ring 1. The position where the second arm 10-2 is rotatably connected to the positioning ring 1 is located on one side of the middle part of the side of the positioning ring 1. A support plate 12 is fixedly provided on the side of the positioning ring 1. When the rotating arm 10 rotates to the first arm 10-1 in a vertical state, the guide ring 4 is located directly above the positioning ring 1, so that each guide hole 5 is located directly above the corresponding rebar positioning hole 3. The outer side of the second arm 10-2 is supported on the support plate 12.

[0024] At this time, by setting the included angle between the first arm 10-1 and the second arm 10-2 to be an obtuse angle, when the guide ring 4 is located directly above the positioning ring 1, the rotating arm 10 is in an eccentric state and is supported by the support plate 12, thereby enabling the rotating arm 10 to stably support the guide ring 4 directly above the positioning ring 1.

[0025] By making the above settings, when using the steel reinforcement hoisting equipment for the steel tower column of the bridge main tower steel-concrete composite construction provided by this invention, the operation can be carried out according to the following steps: Step 1: Using a crane, lift the lifting ring 8. Under the action of the extended strip clamp 11-2, the guide ring 4 is lifted as a whole. The rotating arm 10 will rotate upward with its connection point with the positioning ring 1 as the axis. During the lifting process, the guide ring 4 moves to directly above the positioning ring 1. Then, as the crane continues to lift the lifting ring 8 upward, the guide ring 4 and the positioning ring 1 will be lifted as a whole. In this way, the positioning ring 1 and the guide ring 4 are lifted to the top of the steel tower column. Then, the clamp 2 is used to fix the positioning ring 1 to the top of the steel tower column.

[0026] Step 2: Use the crane to lower the guide ring 4, moving it outward from the steel tower column during the lowering process. At this time, the boom 10 rotates outward around its connection point with the positioning ring 1, and the guide ring 4 follows the boom 10 to move outward from the steel tower column. When the boom 10 rotates to a lateral position, the guide ring 4 is completely outside the steel tower column and supported on the column by the positioning ring 1 through the boom 10. Then, continue lowering the lifting ring 8, and the first lifting rope 7 continues to descend through the guide hole 5, thereby lowering the rebar clamp 11 to the ground.

[0027] Step 3: Use the rebar clamp 11 to clamp and fix the top of the rebar to be installed.

[0028] Step 4: Use the crane again to lift the lifting ring 8 upwards. Before the second lifting rope 9 is tightened, the rebar clamp 11 passes through the guide hole 5 from bottom to top and moves above the guide ring 4. When the second lifting rope 9 is tightened, the bottom end of the rebar is still below the guide hole 5. At this time, the second lifting rope 9 has the function of lifting the guide ring 4 upwards, while the lifting ring 8 has the function of stabilizing the rebar through the first lifting rope 7 and the rebar clamp 11. Afterwards, continue to lift the lifting ring 8 upwards and move the crane boom to the side of the steel tower column. The rebar has a lateral force that stabilizes the guide ring 4 through the guide hole 5, and the second lifting rope 9 has an upward lifting force on the guide ring 4, causing the boom 10 to rotate upwards and finally move the guide ring 4 to a position directly above the positioning ring 1.

[0029] Step 5: Lowering the lifting ring 8. During this process, the rotating arm 10 is stably supported by the support plate 12, so that the guide ring 4 is stably supported in a position directly above the positioning ring 1. As the lifting ring 8 continues to be lowered, the reinforcing bar descends and passes through the reinforcing bar positioning hole 3. Until the reinforcing bar is lowered to the ground, the reinforcing bar sleeve 11 passes through the guide hole 5 from top to bottom and is located between the guide ring 4 and the positioning ring 1.

[0030] Step Six: Operate the rebar clamp 11 to release the rebar. At this point, the top of the strip clamp 11-2 is outside the circumference of the guide hole 5. After the rebar is fixed to the inner wall of the steel tower column, operate the clamp 2 to loosen the top of the steel tower column. At this point, the positioning ring 1 and guide ring 4 are stably supported at the top of the steel tower column by the base plate. Then, lift the lifting ring 8 upwards again. With the strip clamp 11-2 supporting the guide ring 4, the positioning ring 1 and guide ring 4 can be lifted away from the steel tower column.

[0031] Please see Figure 4 and Figure 5As shown, a connecting shaft 13 is fixedly installed on the side of the guide ring 4. A locking block 14 is fixedly sleeved on the outer side of the connecting shaft 13. The end of the locking block 14 away from the connecting shaft 13 has a wedge-shaped structure. The end of the first arm 10-1 away from the second arm 10-2 has two vertically arranged locking grooves 15. The two locking grooves 15 are connected to each other, and the bottom shape of the locking groove 15 is set to match the size of the end of the locking block 14 away from the connecting shaft 13. The bottom of one of the locking grooves 15 faces the first arm 10-1 in a direction parallel to the second arm 10-2.

[0032] By making the above settings, it has the following states: In State 1, when the guide ring 4 is positioned directly above the positioning ring 1, and the lifting ring 8 is lowered using a crane, the tip of the locking block 14, facing downwards, moves into the locking groove 15 of the first arm 10-1 with the bottom facing downwards, and inserts into the locking groove 15. After the locking block 14 is inserted into the locking groove 15, the locking block 14, together with the locking groove 15 and the connecting shaft 13, can lock the guide ring 4, preventing the guide ring 4 from rotating. This ensures that the guide hole 5 and the rebar positioning hole 3 remain aligned, and guides the direction of the rebar downwards, allowing the rebar to be accurately inserted into the rebar positioning hole 3 after being lowered.

[0033] In state two, when the guide ring 4 is located to the side of the positioning ring 1 and the boom 10 is in a horizontal position, the lifting ring 8 is lowered by the crane. The tip of the locking block 14 is inserted into another locking groove 15 with its tip pointing downward. After the locking block 14 is inserted into the locking groove 15, the locking block 14, together with the locking groove 15 and the connecting shaft 13, can lock the guide ring 4 and prevent the guide ring 4 from rotating. This ensures that the guide hole 5 remains vertically downward during the process of lifting the steel bar upward and during the process of the steel bar sleeve 11 passing through the guide hole 5.

[0034] Please see Figures 6 to 9 As shown, the diameter of the guide hole 5 is larger than the outer diameter of the suspended steel bar, and both the upper and lower ends of the guide hole 5 are provided with chamfered angles. The inner sidewall of the guide hole 5 is provided with a first side groove 16. A first side clamping block 17 is slidably arranged in the first side groove 16. A side clamping spring 18 is provided between the first side clamping block 17 and the inner wall of the first side groove 16. A first side clamping groove 19 with an inner diameter that matches the outer diameter of the suspended steel bar is provided on the side of the first side clamping block 17 facing the center of the guide hole 5. Both the upper and lower ends of the groove of the first side clamping groove 19 are provided with chamfered angles that match the guide hole 5. The top of the steel bar clamp 11 is provided with a conical structure, and the top dimension of the conical structure is smaller than the diameter of the first side clamping groove 19.

[0035] With this configuration, when the rebar sleeve 11 passes through the guide hole 5 from bottom to top, the tapered structure at its top end can be corrected in direction by the chamfered angle of the guide hole 5 and the first side clamping block 17, and is inserted into the first side clamping groove 19 along the chamfered angle, thus pushing open the first side clamping block 17 and compressing the side clamping spring 18, providing a channel for the rebar sleeve 11 to pass through the guide hole 5 as a whole. After the rebar sleeve 11 has completely passed through the guide hole 5, the first side clamping block 17, under the elastic action of the side clamping spring 18, can make the rebar and the guide hole 5 aligned, so that when the guide ring 4 is directly above the positioning ring 1, the rebar and the rebar positioning hole 3 are aligned.

[0036] The rope hole 6 and its corresponding guide hole 5 are connected by a strip-shaped through hole 20. A connecting plate 21 that can pass through the strip-shaped through hole 20 is fixedly provided on the side of the surface of the rebar sleeve 11-1 opposite to the rope hole 6. The bottom end of the first lifting rope 7 is fixedly connected to the end of the connecting plate 21 away from the rebar sleeve 11-1, and the first lifting rope 7 is in a vertical state.

[0037] Please see Figures 10 to 13 As shown, the rebar sleeve 11-1 has a hollow columnar structure. Each strip-shaped clamp 11-2 has a first strip-shaped through groove 22. The bottom end of each strip-shaped clamp 11-2 is rotatably connected to the inner walls of both sides of the first strip-shaped through groove 22 via an installation shaft. A torsion spring is disposed between the installation shaft and the side walls of the first strip-shaped through groove 22. The rebar sleeve 11 also includes an outer sleeve 11-3 fitted outside the rebar sleeve 11-1. The outer sleeve 11-3 includes a vertically arranged translational sleeve 11-3-1 and a threaded sleeve 11-3-2. The bottom end of the translational sleeve 11-3-1 is rotatably connected to the top end of the threaded sleeve 11-3-2. Each first strip-shaped through groove 22 on the translational sleeve 11-3-1 has a second strip-shaped through groove 2. 3. When the strip clamp 11-2 is in the unfolded state, its top end extends from the second strip groove 23 to the outside of the translation sleeve 11-3-1. The inner side of the strip clamp 11-2 is set as an arc surface that matches the surface of the suspended steel bar. The top width of the strip clamp 11-2 is greater than its bottom width, so that when the inner side of the strip clamp 11-2 is in a vertical state, its outer side is a slope with the top end tilting outward. The upper part of the outer side of the strip clamp 11-2 is located in the second strip groove 23. The upper part of the outer surface of the steel bar sleeve 11-1 is set as a smooth plane, and the lower part of the outer surface of the steel bar sleeve 11-1 is set as a threaded connection with the threaded sleeve 11-3-2. The conical structure at the top of the steel bar sleeve 11-1 is the top of the translation sleeve 11-3-1.

[0038] The inner top wall of the second strip-shaped through groove 23 is an inclined surface with the inner end sloping downwards. The inner side of the top of the strip-shaped clamping block 11-2 is also an inclined surface with the inner end sloping downwards. When the inner side of the strip-shaped clamping block 11-2 is held vertically on the surface of the reinforcing bar, the outer end of the inclined surface at the top of the strip-shaped clamping block 11-2 is located outside the inner end of the inclined surface of the inner top wall of the second strip-shaped through groove 23.

[0039] By making the above settings, when using the rebar clamp 11 to hold the rebar, the top end of the rebar is first inserted into the inner cavity of the rebar sleeve 11-1 from the bottom end. Then, by rotating the threaded sleeve 11-3-2, the translational sleeve 11-3-1 is moved upward. During the upward movement of the translational sleeve 11-3-1, the inner end of the inner bottom wall of the second strip-shaped through groove 23 causes the strip-shaped clamp 11-2 to rotate inward and clamp onto the surface of the rebar through the outer side of the upper strip-shaped clamp 11-2. During this process, the strip-shaped clamp 11-2, located within the second strip-shaped through groove 23, limits the translational sleeve 11-3-1, preventing the translational sleeve 11-3-1 from rotating when the threaded sleeve 11-3-2 rotates. Furthermore, when releasing the reinforcing bar, the rebar clamp 11 rotates the threaded sleeve 11-3-2 in the opposite direction, causing the translational sleeve 11-3-1 to move downwards. The strip-shaped clamp 11-2 rotates outwards under the action of the torsion spring and resets, releasing the reinforcing bar. Additionally, by continuing to rotate the threaded sleeve 11-3-2 in the opposite direction, the inner top wall of the second strip-shaped through groove 23 is pressed downwards against the inner side of the top of the strip-shaped clamp 11-2, fixing the strip-shaped clamp 11-2 in the unfolded state to ensure its stability when supported on the lower surface of the guide ring 4 in the unfolded state.

[0040] The outer sleeve 11-3 also includes a rotating sleeve 11-3-3 axially slidably connected to the bottom end of the threaded sleeve 11-3-2. The rotating sleeve 11-3-3 is rotatably sleeved on the outside of the rebar sleeve 11-1, and the bottom ends of both the rotating sleeve 11-3-3 and the rebar sleeve 11-1 are set with a conical structure. The inner diameter of the rebar sleeve 11-1 is larger than the outer diameter of the rebar being suspended. A spiral groove 24 is opened on the outer side of the rotating sleeve 11-3-3, and a sliding ball 25 is set in the spiral groove 24. The outer side of the sliding ball 25 is fixedly set. There is a lifting rod 26, and the width of the lifting rod 26 is smaller than the width of the strip-shaped through hole 20. The connecting plate 21 is rotatably sleeved on the top of the translation sleeve 11-3-1. A support plate 27 adapted to its thickness is provided directly below the connecting plate 21. The support plate 27 is fixedly connected to the surface of the steel sleeve 11-1, and the lifting rod 26 slides through the support plate 27 in the height direction. An upper top ring 41 is fixedly provided on the top of the positioning ring 1, and when the guide ring 4 is located directly above the positioning ring 1, the upper top ring 41 is located directly below the lifting rod 26.

[0041] By making the above settings, during the process of rotating the threaded sleeve 11-3-2 and causing the translational sleeve 11-3-1 to move upward, the threaded sleeve 11-3-2 moves upward relative to the rotating sleeve 11-3-3. At the same time, the threaded sleeve 11-3-2 drives the rotating sleeve 11-3-3 to rotate synchronously. During this time, the rotating sleeve 11-3-3 drives the lifting rod 26 to move downward on the support plate 27 through the helical groove 24 and the sliding ball 25. That is, after the steel bar is clamped and fixed by the steel bar clamp 11, the lifting rod 26 is at its lowest position along the length of the steel bar sleeve 11-1. During the process of lowering the reinforcing bar, under the action of gravity, the bottom end of the lifting rod 26 will press against the top end of the upper ring 41, thereby causing the lifting rod 26 to move upward on the support plate 27. During the displacement of the lifting rod 26, the sliding ball 25 drives the rotating sleeve 11-3-3 to rotate in the opposite direction through the spiral groove 24. The rotating sleeve 11-3-3 in the opposite direction will drive the threaded sleeve 11-3-2 to rotate in the opposite direction. At this time, the threaded sleeve 11-3-2 will drive the translational sleeve 11-3-1 to move downward, thereby causing the strip clamp 11-2 to unfold and automatically release the reinforcing bar.

[0042] The diameter of the rope hole 6 is larger than the outer diameter of the first suspension rope 7, and both the upper and lower ends of the rope hole 6 are provided with chamfered angles. The inner wall of the rope hole 6 is provided with a second side groove 28 that communicates with the first side groove 16. The inner side of the first side clamping block 17 is fixedly provided with a second side clamping block 29 that slides in the second side groove 28. The side of the second side clamping block 29 facing the center of the rope hole 6 is provided with a second side clamping groove 30 whose inner diameter is similar to the outer diameter of the first suspension rope 7. Both the upper and lower ends of the groove of the second side clamping groove 30 are provided with chamfered angles that are adapted to the rope hole 6. The end of the connecting plate 21 away from the translation sleeve 11-3-1 is fixedly provided with an upper connecting sleeve 31 with both ends being conical. The upper connecting sleeve 31 is fixedly sleeved on the bottom end of the suspension rope. The end of the support plate 27 away from the steel sleeve 11-1 is fixedly provided with a lower connecting sleeve 32 with both ends being conical. The bottom end of the upper connecting sleeve 31 is fixedly provided with a connecting rod 33 that slides into the top end of the lower connecting sleeve 32.

[0043] Furthermore, the bottom height of the tapered portion of the upper connecting sleeve 31 is greater than the top height of the translation sleeve 11-3-1, and the top height of the tapered portion of the lower connecting sleeve 32 is less than the bottom height of the reinforcing bar sleeve 11-1. A slot 34 is provided on the inner side of the second side clamping block 29, and a rod 35 is inserted into the slot 34. A hole 36 is provided on the guide ring 4 for the rod 35 to pass through. A rod spring 37 is provided between the hole 36 and the rod 35 to provide elastic force for the rod 35 to be inserted into the hole 36. Two rods 35 corresponding to the same rope through hole 6 are also provided. The outer end of 5 extends into the inner cavity of the guide ring 4 and is connected to the arc plate 38. The inner surface of the arc plate 38 is fixed with an outer top plate 39 on both the upper and lower sides. The upper and lower surfaces of the guide ring 4 are provided with displacement grooves 40 for the inner and outer displacement of the outer top plate 39. The inner end of the displacement groove 40 is connected to the rope hole 6. The top of the outer top plate 39 extends into the rope hole 6. The top and bottom of the inner end of the outer top plate 39 are chamfered. When the first suspension rope 7 is in the rope hole 6, the outer top plate 39 is pushed outward by the first suspension rope 7, so that the insertion rod 35 is outside the slot 34.

[0044] By making the above settings, when the first side clamp 17 is held on the surface of the reinforcing bar, the insert rod 35 is inserted into the slot 34. At this time, the cooperation between the insert rod 35 and the slot 34 can prevent the first side clamp 17 from detaching from the surface of the reinforcing bar, improve the limiting and positioning effect on the reinforcing bar, and ensure that the reinforcing bar and the reinforcing bar positioning hole 3 are aligned when the guide ring 4 is located directly above the positioning ring 1.

[0045] Furthermore, before the rebar sleeve 11 passes through the guide hole 5 from bottom to top, the top end of the upper connecting sleeve 31 is first inserted into the second side clamping groove 30 to open the two second side clamping blocks 29. At this time, the first side clamping block 17 moves synchronously with the second side clamping block 29, so that the first side clamping groove 19 between the two first side clamping blocks 17 moves away from each other, thereby making it easier for the top end of the translation sleeve 11-3-1 to be inserted into the first side clamping groove 19 to open the two first side clamping blocks 17, so that the rebar sleeve 11 can pass through the guide hole 5.

[0046] Before the rebar sleeve 11 passes through the guide hole 5 from bottom to top, the first lifting rope 7 causes the insertion rod 35 to be disengaged from the insertion hole 36, thereby allowing the first side clamp 17 and the second side clamp 29 to be outwardly expanded. After the rebar sleeve 11 passes through the guide hole 5 from bottom to top, under the action of the side clamp spring 18, the first side clamp 17 and the second side clamp 29 return to their initial state. At this time, under the action of the rod spring 37, the insertion rod 35 is reinserted into the slot 34, thereby fixing the first side clamp 17 and the second side clamp 29. This allows the first side clamp 17 to be tightly attached to the surface of the rebar, keeping the rebar in a vertical state so that when the guide ring 4 is directly above the positioning ring 1, the rebar and the rebar positioning hole 3 are aligned.

[0047] The guide ring 4 has a rope retainer 42 fixedly installed on its inner side. The bottom end of the second lifting rope 9 extends outward from the inner side of the rope retainer 42 and is connected to the inner surface of the guide ring 4. The inner ring 43 is provided in the inner cavity of the lifting ring 8, and the top end of the second lifting rope 9 is fixedly connected to the inner ring 43. By setting the rope retainer 42 and the inner ring 43, when the reinforcing bar and the reinforcing bar sleeve 11 are lowered, the falling part of the second lifting rope 9 is located within the inner circle of the rope retainer 42, which can prevent the second lifting rope 9 from getting tangled with the reinforcing bar.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
