Description

Technical Field

[0001] This utility model relates to the field of bridge steel bar hoisting and installation technology, and in particular, to a tower column steel bar transfer system. Background Technology

[0002] Cable-stayed bridges, as one of the most popular bridge types, play an irreplaceable role in bridge construction. Common cable-stayed bridge pylon structures include: single-column, double-column, portal, inclined-leg portal, inverted V-shaped, inverted Y-shaped, H-shaped, and A-shaped.

[0003] The cable-stayed bridge tower on the Guangdong Delta Plain is an A-shaped reinforced concrete structure with a total height of 124.7m. The tower column has a D-shaped single-box single-cell cross-section and includes a base, lower tower column, middle tower column, upper tower column, upper crossbeam, and tower crown. The lower tower column has an inward tilt of 1 / 6.57 and an outward tilt of 1 / 4.53; the middle tower column has an inward and outward tilt of 1 / 6.57; and the upper middle tower column has an outward tilt of 1 / 6.57. The tower column was constructed in 33 segments, with a standard vertical pouring height of 3.9m. Each segment's main reinforcement consists of 634 HRB500E 40mm diameter steel bars in the outer layer and 159 HRB400E 32mm diameter steel bars in the middle layer, resulting in a dense arrangement of main reinforcement. Mechanical connections are used for the long butt joints between the main reinforcement bars in each segment. The tower column formwork adopts hydraulic climbing formwork. The outer climbing formwork frame is equipped with a total of 5 operating platforms according to the platform height requirements for on-site concrete construction and rebar tying. The top rebar tying platform surrounds the outer perimeter of the tower column, forming a "D"-shaped operating platform with a width of 2.0m. It is inevitable that rebar hoisting and rebar splicing and installation will be carried out simultaneously on the same vertical plane, which is prone to safety risks such as falls from height and falling objects.

[0004] In the complex working environment of confined construction space and steeply inclined cable towers, the traditional method for hoisting the main reinforcing bars of cable tower columns is as follows: first, the reinforcing bars are hoisted to the operating platform using a horizontal two-point hoisting method, and then manually transported, erected, and connected to the tower column. For example, patent application number CN202111365241.2 discloses a sling anti-slip device for vertically hoisting tunnel segments, which includes a fixing mechanism for clamping and fixing both ends of the tunnel segment and a connecting mechanism for fixing the top of the fixing mechanism. The fixing mechanism includes a vertically arranged extension and docking mounting plate and an upper clamping component and a lower clamping component arranged on the extension and docking mounting plate. The upper and lower clamping components are arranged opposite to each other, with the upper clamping component abutting against the upper surface of the tunnel segment and the lower clamping component abutting against the lower surface of the tunnel segment. As disclosed in patent application number CN202311612128.9, a lifting device and method for assisting in the installation of reinforcing bars in bridge piers are provided. This lifting device includes a U-shaped steel plate and lifting rings. The lifting rings are U-shaped, and both ends are fixed to the sides of the U-shaped steel plate. Multiple fixing holes are provided on the bottom plate of the U-shaped steel plate. Positioning pins are provided at the fixing holes. The positioning pins are hollow rods with ring stops at their upper ends, and multiple openings are provided from bottom to top on the rod body. The process includes: S1. Placing the lifting device horizontally on the ground, with the openings of the U-shaped steel plate facing parallel to the ground; S2. Extending and installing the positioning pins in the positioning holes; S3. Passing the reinforcing bars through the positioning pins sequentially from front to back, adjusting the insertion length, and then tightening; S4. Fixing the slings to the lifting rings using a crane or hoist; S5. Lifting the lifting device to place the reinforcing bars in batches at the binding positions, and dismantling the lifting device after the reinforcing bars are bound. As disclosed in patent application number CN202420421079.4, an installation and positioning clamp for pier reinforcement includes a main frame with multiple sleeves on the main frame. Each sleeve includes a movable arc-shaped clamping piece. Limiting wire ropes are provided on both sides of the main frame, and the limiting wire ropes abut against the bottom of the multiple sleeves. The sleeves are used to clamp the reinforcement. As disclosed in patent application number CN202120839838.5, a reinforcement hoisting and clamping device includes a hoisting plate and two clamping plates. The hoisting plate has multiple through holes for reinforcement to pass through, and the through holes are spaced apart along the center line of the hoisting plate. The clamping plates can be slidably set on the hoisting plate in a direction perpendicular to the center line of the hoisting plate. The two clamping plates are arranged opposite each other and parallel to the center line of the hoisting plate. Each clamping plate has a semi-circular clamping groove at the position corresponding to each through hole. The radius of the semi-circular clamping groove is smaller than that of the through hole. The hoisting plate is provided with a pushing mechanism for pushing the two clamping plates to move towards each other.A rebar anti-fall hoisting device, as disclosed in patent application CN202120152645.2, includes a hoisting structure, a suspension structure, and a hoisting power equipment. The hoisting structure includes a bearing container respectively disposed at both ends of the rebar to be hoisted. The bearing container includes a container body, with a receiving cavity inside the container body. A closed structure is provided at one end of the receiving cavity, and an opening is provided at the other end of the receiving cavity. The bearing container is sleeved onto the rebar to be hoisted through the opening. The suspension structure includes a first rope structure, with both ends of the first rope structure connected to the openings of the bearing containers disposed at both ends of the rebar to be hoisted. The hoisting power equipment is connected to the middle of the first rope structure through a connecting structure. A device for hoisting rebar, as disclosed in patent application CN201620403357.9, includes a rebar and a hook of a hoisting machine for hoisting the rebar. The rebar is bound at two points by a wire rope. A sleeve is fitted onto one end of the rebar. One end of the wire rope is connected to the hook, and the other end is connected to the sleeve through a connecting rope. A steel bar hoisting assembly, as disclosed in patent application CN202323631986.6, includes a hoisting component and an auxiliary locking component. The hoisting component is fixed to a hoisting rope, and the auxiliary locking component is slidably adjustable on the hoisting rope. One end of a steel bar can be inserted into the hoisting component, and the steel bar can be vertically inserted into the hoisting component. The auxiliary locking component can lock the other end of the steel bar.

[0005] The defects of the above-mentioned steel bar hoisting method are as follows: The first method of hoisting steel bars requires stacking the steel bars on the operating platform. If the stacked steel bars exceed the maximum load-bearing capacity of the formwork frame, it may lead to the risk of the formwork frame falling and operator injury or death. Alternatively, because the steel bars are 4m long, it is not convenient to manually handle and erect the steel bars in the narrow "D"-shaped operating platform space, which reduces the efficiency of steel bar splicing and installation.

[0006] The second method of lifting steel bars is only applicable to lifting segments with a ring width of 1.2m to 1.5m. However, it cannot be completely replicated for lifting steel bars with a length of 4m, making it difficult to lift steel bars. For example, if the steel bar is too long, the anti-slip device of the sling may not be able to hold the steel bar, causing the steel bar to fall from a height and injure people.

[0007] The third to fifth methods of steel bar hoisting involve the hoisting of large quantities of horizontal steel bars. During the hoisting process, the weight of the steel bars causes the hoisting device and the hoisted steel bars to be in a vertical position in the air, intersecting with the axial direction of the main steel bars of the inclined tower column at a certain angle. This makes the aerial splicing and connection of the main steel bars of the tower column difficult to construct, and the quality of the splicing and connection does not meet the design requirements of Class I joints.

[0008] The sixth method of steel bar hoisting is the horizontal two-point hoisting method. Although it has the advantages of preventing steel bars from slipping, reducing safety risks, and protecting the quality of steel bar threads, the steel bars are 4m long. In the narrow “D”-shaped operating platform space, it is not convenient to manually handle and erect the steel bars, which reduces the efficiency of steel bar splicing and installation.

[0009] The seventh method of rebar hoisting is the single-point vertical hoisting method. While it has advantages such as safety, reliability, high efficiency, and good protection of rebar threads, the flat-bottomed circular end of the hoisting device sleeve presents several drawbacks when unloading rebar inside the column. For example, if the rebar and hoisting device are placed vertically, the rebar's length and high center of gravity often cause it to tip over, injuring people or property, requiring manual repositioning and wasting manpower. Conversely, if the rebar and hoisting device are placed at an angle, the circular bottom of the sleeve can cause it to roll sideways, leading to rebar falling and injuring people or property. This method is not fully replicable for hoisting and splicing the main rebar of highly inclined cable-stayed tower columns. It is difficult to achieve the splicing and splicing of main rebar in highly inclined tower columns, requiring manual extraction and rotation of the rebar, which is not only time-consuming and labor-intensive but also carries the potential safety risks of rebar tipping over and the hoisting device rolling, causing injury or property damage.

[0010] The eighth method of steel bar hoisting is the single-point vertical hoisting method. While it has advantages such as preventing steel bars from falling during high-altitude hoisting operations, avoiding accidents caused by falling objects, and ensuring good protection of the steel bar threads, it also has drawbacks. Because the bottom of the steel bar hoisting assembly is square, when unloading the steel bars on the operating platform, if the steel bars and hoisting device are placed vertically, the steel bars are often too long and have a high center of gravity, causing them to tip over and injure people or property. This requires manual repositioning of the steel bars, wasting manpower. This hoisting method cannot be completely replicated for hoisting and splicing the main steel bars of large-inclined cable towers. It is difficult to achieve the splicing and splicing of main steel bars for large-inclined cable towers, requiring manual extraction and rotation of the steel bars, which is not only time-consuming and labor-intensive but also poses potential safety risks of steel bars tipping over and the hoisting device rolling, causing injury or property damage.

[0022] This utility model has the following beneficial effects: In the rebar transfer system for cable tower columns of this utility model, the end support cylinder of the rebar hoisting device has an end mounting cavity for securing the end of the rebar bundle.

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0028] Reference Figure 1-2 , Figure 6 A preferred embodiment of this utility model provides a tower column rebar transfer system, comprising: a rebar hoisting device 5 for hoisting rebar, and a rebar support device 6 that works in conjunction with the rebar hoisting device 5 to provide vertical and inclined stable support for the rebar. The rebar hoisting device 5 includes an end support cylinder and a hoisting rope assembly. One end of the end support cylinder is recessed along the axial direction to form an end mounting cavity, which is used to hold the bottom end of a rebar bundle 4 composed of multiple rebars to be hoisted. One end of the hoisting rope assembly is connected to the end support cylinder, and the other end of the hoisting rope assembly is used to wrap around and bind the upper end of the rebar bundle 4 and then connect to the hoisting equipment 8. The outer surface of the end support cylinder also has a circumferentially arranged polyhedral support structure, so that the hoisted body formed by the rebar bundle 4 hoisted by the rebar hoisting device 5 can be stably horizontally or inclinedly supported. The rebar support device 6 is used for detachable fixing to the main rebar 2 of the tower column or the climbing formwork frame, and has a latch for holding the upper end of the hoisted body. The latch cooperates with the end support cylinder to provide vertical and inclined stable support for the hoisted body.

[0029] In the tower column steel bar transfer system of this utility model, the end support cylinder of the steel bar hoisting device 5 has an end mounting cavity for clamping the end of the steel bar bundle 4. During hoisting, the bottom end of the steel bar bundle 4 to be hoisted is inserted into the end mounting cavity, which not only ensures that the steel bar bundle 4 to be hoisted is not easy to fall during hoisting, but also protects the threads (threads) at the end of the steel bar bundle 4 to be hoisted from being swayed and damaged during hoisting, effectively protecting the quality of the threads (threads) at the end of the steel bar bundle 4 to be hoisted. On the other hand, the outer surface of the end support cylinder also has a circumferentially arranged polyhedral support structure. This polyhedral support structure not only contacts the ground, allowing the hoisting body assembled from the rebar hoisting device 5 and the rebar bundle 4 to be in an inclined state on the tower top or the operating platform 3 of the climbing formwork, facilitating quick and convenient manual removal and splicing of the rebars to be installed; but also, through the stable contact with the ground, the polyhedral support structure ensures the hoisting body is in a vertical state in the air. This facilitates both the safety confirmation of the rebar hoisting device 5 and the rebar bundle 4 before formal hoisting and the safe operation of the rebar hoisting device 5 and the rebar bundle 4. The steel bar hoisting device 5 is temporarily placed on the operating platform 3 to prevent tipping over and injuring people or property, or rolling sideways and causing injury. Furthermore, the multi-faceted support structure at the bottom of the device ensures stable contact with the ground, preventing sideways and rolling injuries. This allows the hoisting device 5 and the steel bar bundle 4 to be in an inclined position in the air. Combined with the steel bar support device 6, the hoisting body is tilted and supported, facilitating quick and easy manual removal and splicing of the steel bars to be installed. This eliminates the need for manual pulling and erection of the steel bars, reducing labor intensity, shortening the splicing and splicing time, and improving installation efficiency.

[0030] In the tower column rebar transfer system of this utility model, through the coordinated use of the rebar hoisting device 5 and the rebar support device 6, not only can it prevent the rebar bundle 4 to be hoisted from slipping and falling during high-altitude hoisting in confined construction spaces, thus avoiding injury to people and property, but it can also solve the safety hazards of the rebar bundle 4 to be hoisted falling and injuring people and property in confined "D"-shaped operating platform spaces due to the conventional circular bottom end of the rebar hoisting device 5, or due to the conventional square bottom end of the rebar hoisting device 5 and the rebar bundle 4 being too long and having a high center of gravity. This achieves safe high-altitude hoisting of the main rebar 2 of the tower column and improves the safety and reliability of hoisting the main rebar 2 of the tower column.

[0031] Optionally, such as Figure 3 As shown, the end support cylinder includes a hollow straight cylinder 501 with both ends connected and hollow cylindrical in shape, and a multi-faceted hollow frustum 502 fixedly connected to the end of the hollow straight cylinder 501. The multi-faceted hollow frustum 502 closes the end of the hollow straight cylinder 501, so that the inner cavity of the hollow straight cylinder 501 forms an end mounting cavity, and the outer peripheral surface of the multi-faceted hollow frustum 502 forms a multi-faceted support structure. During the hoisting operation, the bottom end of the steel bar bundle 4 to be hoisted is inserted into the hollow straight cylinder 501 and abuts against the end face of the multi-faceted hollow frustum 502, ensuring that the steel bar bundle 4 to be hoisted does not fall during hoisting. At the same time, it protects the threads (threads) at the end of the steel bar bundle 4 from being swayed and damaged during hoisting, effectively protecting the quality of the threads (threads) at the end of the steel bar bundle 4 to be hoisted.

[0032] In this optional solution, such as Figure 4As shown, the multifaceted hollow frustum 502 includes a circular steel plate 5021 fixed to the end face of a hollow straight cylinder 501 to close the end of the hollow straight cylinder 501, a circular steel rod 5022 vertically fixed along the axial direction to the center of the circular steel plate 5021, and multiple polygonal steel plates 5023 arranged at intervals along the circumference of the circular steel rod 5022. The inner sides of each polygonal steel plate 5023 are respectively fixedly connected to the circular steel plate 5021 and the circular steel rod 5022, and the multiple polygonal steel plates 5023 form a multifaceted support structure. In this optional scheme, the main functions of setting up the multi-faceted hollowed-out cone 502 in the steel bar hoisting device 5 are: (1) First, to strengthen the connection between the circular steel plate 5021 and the circular steel bar 5022, and increase the overall stability of the steel bar hoisting device 5; second, through the contact between the side slope of the multi-faceted hollowed-out cone 502 and the ground, the hoisting body can be in an inclined state on the operating platform 3, so that it is convenient for manual labor to quickly and easily take out and extend the steel bar to be installed. (2) Through the stable contact between the side slope of the multi-faceted hollowed-out cone 502 at the bottom of the steel bar hoisting device 5 and the ground without causing lateral rolling and injury, the steel bar hoisting device 5 and the steel bar to be installed can be in an inclined state in the air. Combined with the function of the steel bar support device 6, the hoisting body is tilted and supported, so that it is convenient for manual labor to quickly and easily take out and extend the steel bar to be installed, saving the amount of manual labor for pulling out and erecting the steel bar to be installed, reducing the intensity of manual labor, shortening the extension and connection installation time of the steel bar to be installed, and improving the extension and connection installation efficiency.

[0033] In specific embodiments of this optional solution, such as Figure 4 As shown, the polygonal steel plate 5023 is a pentagonal steel plate, including long and short edges spaced parallel to each other axially, long and short straight edges spaced parallel to each other radially and perpendicularly connected to the long and short edges at both ends, and a long inclined side connecting the short straight edge and the short edge. The long edges are fixed to the circular steel plate 5021 and extend radially along the circular steel plate 5021, while the short edges are flush with the top of the circular steel rod 5022 and extend radially along the circular steel rod 5022. The long straight edge is fixed axially to the outer wall surface of the circular steel rod 5022. During hoisting, the small end face of the hollowed-out polygonal structure of the multi-faceted hollowed-out cone-shaped body 502 at the bottom of the steel bar hoisting device 5 is in stable contact with the ground, which can keep the hoisting body in a vertical state in the air. This is convenient for the safety confirmation of the steel bar hoisting device 5 and the steel bar bundle 4 to be hoisted before the formal hoisting, and also convenient for the steel bar hoisting device 5 and the steel bar bundle 4 to be hoisted to be temporarily placed on the operating platform 3, so as to prevent tipping over and causing injury or damage to objects, or rolling to the side and side and causing injury.

[0034] The function of setting the pentagonal steel plate in the multifaceted hollow frustum 502: ① When the polygonal steel plate 5023 is pentagonal, it is welded to the circular steel plate 5021 and the circular steel bar 5022 to form a multi-faceted hollowed-out frustum 502 with one end being a hollowed-out hexagonal (or hollowed-out circular) small end face, the middle part being a hollowed-out hexagonal frustum, and the other end being a hollowed-out cylinder. This not only increases the bearing area at the hollowed-out hexagonal (or hollowed-out circular) end of the circular steel bar 5022, enabling it to withstand the weight of the steel bar hoisting device 5 and the steel bar bundle 4 to be hoisted, but also ensures that when the side slope of the hollowed-out hexagonal frustum contacts the ground, the long inclined steel plates on both sides of the side slope of the hollowed-out hexagonal frustum serve as supporting force-bearing sides, making the support of the steel bar hoisting device 5 and the steel bar bundle 4 more stable, preventing them from swaying or rolling and causing injury or damage.

[0035] ② A short straight edge is set on the hypotenuse of the polygonal steel plate 5023. After being welded with the circular steel plate 5021 and the circular steel bar 5022, a hollow cylinder is formed. A hollow hexagon (or hollow circle) is formed at the intersection of the short straight edge and the long hypotenuse. This mainly serves to transition from the solid cylinder at the end of the circular steel plate to the hollow hexagonal truncated cone, preventing the solid cylinder from rolling easily. When the side slope of the hollow hexagonal truncated cone contacts the ground, the long hypotenuse steel plates on both sides of the side slope of the hollow hexagonal truncated cone act as supporting force sides, making the support of the steel bar hoisting device 5 and the steel bar bundle 4 to be hoisted more stable, preventing them from swaying or rolling and causing injury to people or property.

[0036] ③ When the polygonal steel plate 5023 is quadrilateral, it is welded to the circular steel plate 5021 and the circular steel bar 5022 to form a multi-faceted hollowed-out frustum 502 with one end being a hollowed-out hexagonal (or hollowed-out circular) small end face, the middle part being a hollowed-out hexagonal frustum, and the other end being a circular steel plate solid cylinder with a circular end face. At the hollowed-out hexagonal (or hollowed-out circular) end of the circular steel bar, although the bearing area is increased to withstand the weight of the steel bar hoisting device 5 and the steel bar bundle 4 to be hoisted, when the side slope of the hollowed-out hexagonal frustum contacts the ground, the hollowed-out hexagonal (or hollowed-out circular) end of the circular steel bar serves as the support point, while the solid circular end of the circular steel plate is prone to rolling, causing the steel bar hoisting device 5 and the steel bar bundle 4 to be hoisted to sway sideways, resulting in injury to people and property.

[0037] ④ When the polygonal steel plate 5023 is triangular, it is welded to the circular steel plate 5021 and the circular steel bar 5022 to form a multi-faceted hollowed-out truncated cone 502, with one end being the round end face of a circular steel bar, the middle being a hollowed-out six-sided truncated cone, and the other end being the round end face of a solid cylindrical circular steel plate. When the inclined side of the hollowed-out six-sided truncated cone contacts the ground, the circular steel bar end and the solid cylindrical end of the circular steel plate, being solid circles at both ends, are prone to rolling, which can easily cause the rebar hoisting device 5 and the rebar bundle 4 to be hoisted to roll sideways, causing injury or damage to people and property. When the circular end face of the circular steel bar contacts the ground, the small bearing area of ​​the circular end face cannot withstand the weight of the heavier rebar hoisting device 5 and the rebar bundle 4 to be hoisted, thus damaging the rebar hoisting device 5.

[0038] Optionally, such as Figure 3 As shown, the end support cylinder also includes two lifting rings 503 symmetrically connected to the two opposite outer walls of the hollow straight cylinder 501. The center of the lifting hole of the lifting ring 503 is 30mm to 50mm away from the outer wall of the hollow straight cylinder 501.

[0039] Furthermore, such as Figure 2 and Figure 5 As shown, the lifting rope assembly includes a connecting rope 505 and a lifting wire rope 506. Both ends of the connecting rope 505 are detachably connected to two lifting rings 503 via first shackles 504. One end of the lifting wire rope 506 is connected to the middle of the connecting rope 505 via the first shackle 504, and the other end of the lifting wire rope 506 is used to connect to the lifting equipment 8 after being wrapped around the upper end of the reinforcing bar bundle 4. In this optional solution, such as... Figure 5 As shown, the first shackle 504 consists of a shackle body 5041, a shackle hook 5042, and a movable pin 5043. The shackle body 5041 is made of high-strength alloy steel, stainless steel, or aluminum alloy, the shackle hook 5042 is a D-shaped shackle, and the movable pin 5043 is a spiral pin.

[0040] In this optional scheme, the lifting rings 503 on both sides of the hollow cylinder 501 form a symmetrical cantilevered lifting point force-bearing structure fixed on both sides of the steel bar lifting device 5. Its functions are: firstly, to facilitate the installation and removal of the first shackle 504 connecting the connecting rope 505 and the steel bar lifting device 5 during the lifting of the steel bar bundle 4, preventing damage to the steel bar bundle 4; secondly, compared with the two-point lifting method fixed close to the outer wall of the hollow cylinder 501, in a horizontal two-point lifting system, increasing the distance between the two lifting points reduces the horizontal angle between the connecting rope 505 and the steel bar lifting device 5, ensuring that the horizontal angle meets the requirements of the "Safety Technical Specification for Lifting and Hoisting Engineering in Building Construction" (JGJ276): within the range of 45° to 60°; it can distribute the load, reduce single-point stress, thereby improving overall stability; and it can make the stress on the lifting points more uniform, avoiding excessive stress on some lifting points that could damage the steel bar lifting device 5, leading to the steel bar bundle 4 falling from a height and causing injury.

[0041] Optionally, such as Figure 6 As shown, the reinforcing bar support device 6 includes a telescopic support rod 603 extending axially, and a support frame 601 and a fixing frame 602 connected to both ends of the support rod 6031 along its length. The telescopic support rod 603 is telescopically extendable along its length and adjustable along its radial direction. The fixing frame 602 is used for detachable fixing to the main reinforcing bar 2 of the tower column or the climbing formwork. The support frame 601 is provided with a locking slot.

[0042] In this optional solution, such as Figure 6 and Figure 8 As shown, the telescopic support rod 603 includes two axially spaced support rods 6031, an adjusting rod 6032 connected between the two support rods 6031, and two sets of first connecting assemblies 604. The outer ends of the two support rods 6031 are respectively connected to the support frame 601 and the fixing frame 602. The adjusting rod 6032 is a hollow cylindrical shape with both ends connected, and its inner diameter is larger than the outer diameter of the support rod 6031. Several first adjusting holes 60321 are machined on the outer circle of the adjusting rod 6032, and several second adjusting holes 60311 are provided on the inner ends of the two support rods 6031. The inner ends of the two support rods 6031 extend into the adjusting rod 6032 from both ends, and are adjustablely fixed to the adjusting rod 6032 through a set of first connecting assemblies 604 with the first adjusting holes 60321 and the second adjusting holes 60311.

[0043] In use, the axial position between the second adjustment hole 60311 of the support rod 6031 and the first adjustment hole 60321 of the adjustment rod 6032 in the telescopic support rod 603 is adjusted to lengthen the telescopic support rod 603, thereby adjusting the distance between the support frame 601 and the fixed frame 602. This, in turn, adjusts the tilt angle of the temporarily placed steel bar hoisting device 5 and the steel bar to be installed on the operating platform 3 to be close to the tilt angle of the main steel bar 2 of the tower column. On the other hand, by adjusting the radial position between the second adjustment hole 60311 of the support rod 6031 and the first adjustment hole 60321 of the adjustment rod 6032 in the telescopic support rod 603, different radial angles of the support frame 601 or the fixed frame 602 are adjusted, thereby achieving horizontal or vertical fixed installation of the adjustable steel bar support device 6. In this optional scheme, the cooperation between the steel bar support device 6 and the steel bar hoisting device 5 makes the inclination angle of the steel bar hoisting device 5 and the steel bar to be installed close to the inclination angle of the main steel bar 2 of the tower column. This makes it easier for manual labor to quickly and conveniently remove and connect the steel bar to be installed, eliminating the workload of manually pulling out and erecting the steel bar to be installed, reducing the intensity of manual labor, shortening the time for connecting the steel bar to be installed, and improving the efficiency of connecting the steel bar to be installed.

[0044] Optionally, such as Figure 6-8As shown, the support frame 601 includes a semi-ring-shaped semi-ring frame 6011 and a first connecting rod 6012 connected to the outer wall of the semi-ring frame 6011. The opening of the semi-ring frame 6011 forms a bayonet, and the first connecting rod 6012 is connected to the support rod 6031 on the corresponding side. The fixing frame 602 includes a second shackle 6021 and a second connecting rod 6022 connected to the outer wall of the second shackle 6021. The second connecting rod 6022 is connected to the support rod 6031 on the corresponding side.

[0045] Furthermore, the reinforcing bar support device 6 also includes two sets of second connecting assemblies 605 for connecting the support frame 601 and the fixing frame 602 to the two ends of the telescopic support rod 603, respectively. The second connecting rod 6022 has the same structure as the first connecting rod 6012. The first connecting rod 6012 includes a fixing part that is fixed to the semi-ring frame 6011, and a connecting part that is rod-shaped and connects to the fixing part. The outer end of the telescopic support rod 603 is recessed to form a notch. The connecting part of the first connecting rod 6012 extends into the notch. After the second connecting assembly 605 passes through the notch and the connecting part, it adjustably connects the support frame 601 and the telescopic support rod 603. In this optional embodiment, the first connecting assembly 604 and the second connecting assembly 605 have the same structure, both including connecting bolts, lock nuts, and washers. In use, by loosening the locking nut of the second connecting component 605 between the telescopic support rod 603 and the support frame 601, the support frame 601 is adjusted up and down to the required angle, and then the locking nut is tightened to adjust the pitch angle of the support frame 601; by loosening the locking nut between the telescopic support rod 603 and the fixed frame 602, the fixed frame 602 is adjusted up and down to the required angle, and then the locking nut is tightened to adjust the pitch angle of the fixed frame 602, thereby adjusting the supported tilt angle of the hoisting body temporarily placed on the operating platform 3 to be close to the tilt angle of the main steel bar 2 of the tower column.
