Description

Technical Field

[0001] This application relates to the field of hoisting equipment technology, and in particular to a hoisting device for the entire precast beam steel cage. Background Technology

[0002] In the existing precast beam steel cage production process, the operation mode of separating the steel cage binding prefabrication area and the concrete pouring and curing area is generally adopted, which can optimize production efficiency and reduce the number of molds required.

[0003] However, this operating mode requires transferring the completed steel cages from the prefabrication area to the pouring area. The steel cages that have not been poured with concrete are large in volume and lack structural strength, posing a serious challenge to the transfer process.

[0004] Currently, multi-point hoisting equipment is often used to directly transport steel cages. However, because steel cages are flexible mesh structures, they are prone to irreversible deformation, twisting, or even breakage during hoisting due to uneven stress or localized stress concentration. This seriously affects the subsequent pouring quality and structural safety. In addition, this method of using multi-point hoisting equipment requires a large number of hoisting points, resulting in low hoisting efficiency. Utility Model Content

[0005] To address or partially address the problems existing in related technologies, this application provides a hoisting device for the entire precast beam reinforcement cage, which can adapt to the shape of the reinforcement cage and distribute the load, reduce the number of required hoisting points, and reduce the risk of local stress concentration.

[0006] This application provides a hoisting device for the entire precast beam steel cage, including: a hanger and a plurality of lifting straps installed on the hanger; The lifting device includes: a lifting pipe fixing ring, a lifting strap, and a steel bar fixing ring; The pipe fixing ring consists of two arc-shaped retaining rings. The first fixing through holes are provided on the upper and lower sides of the arc-shaped retaining rings, and the first lifting strap hole is provided below the retaining rings. The rebar fixing ring is a notched retaining ring. Second fixing through holes are provided on the two side walls of the rebar fixing ring, and a second lifting strap hole is provided at the top of one long side wall of the rebar fixing ring. The lifting sling is equipped with lifting rings at both ends. The two lifting rings are installed in the first lifting sling hole and the second lifting sling hole, respectively. The lifting sling connects the pipe fixing ring and the steel bar fixing ring. The width of the first lifting sling hole and the second lifting sling hole is the same as the width of the lifting sling.

[0007] Optionally, in some implementations of the first aspect: Both the pipe fixing ring and the rebar fixing ring are equipped with rubber anti-slip pads.

[0010] Optionally, in some implementations of the first aspect: The hoisting equipment also includes: two gantry cranes; The top of the gantry has two sets of lifting rings.

[0011] The technical solution provided in this application may include the following beneficial effects: This application combines a lifting pipe fixing ring, a lifting strap, and a rebar fixing ring. Compared to commonly used fixing rings, the lifting pipe fixing ring can adapt to the shape of the rebar cage and distribute the load evenly, thereby reducing the number of lifting points required, lowering the risk of local stress concentration, and effectively preventing deformation or damage to the lifting structure. At the same time, by working with the lifting strap, a flexible connection system can be formed to adapt to the irregular shape of the rebar cage and evenly distribute the lifting load, effectively preventing the rebar cage from twisting or breaking during lifting, thus improving the stability and safety of the lifting.

[0020] In the existing precast beam steel cage production process, the operation mode of separating the steel cage binding prefabrication area and the concrete pouring and curing area is generally adopted, which can optimize production efficiency and reduce the number of molds required.

[0021] However, this operating mode requires transferring the completed steel cages from the prefabrication area to the pouring area. The steel cages that have not been poured with concrete are large in volume and lack structural strength, posing a serious challenge to the transfer process.

[0022] Currently, multi-point hoisting equipment is often used to directly transport steel cages. However, because steel cages are flexible mesh structures, they are prone to irreversible deformation, twisting, or even breakage during hoisting due to uneven stress or localized stress concentration. This seriously affects the subsequent pouring quality and structural safety. In addition, this method of using multi-point hoisting equipment requires a large number of hoisting points, resulting in low hoisting efficiency.

[0023] To address the aforementioned issues, this application provides a hoisting device for the entire precast beam reinforcement cage, which can adapt to the shape of the reinforcement cage and distribute the load, reducing the number of required lifting points and lowering the risk of local stress concentration.

[0024] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] Figure 1 This is a schematic diagram of an overall structure of the hoisting device in an embodiment of this application; Figure 2 This is a schematic diagram of the sling device in one embodiment of this application; Figure 3 This is a schematic diagram of a structure of the pipe fixing ring in an embodiment of this application; Figure 4 This is a structural schematic diagram of a steel bar fixing ring in an embodiment of this application.

[0026] See Figure 1-4 A hoisting device for the whole precast beam steel cage includes: a hanger 1 and a plurality of sling devices 2 installed on the hanger 1.

[0027] The lifting device 2 includes: a lifting pipe fixing ring 201, a lifting belt 202, and a steel bar fixing ring 203.

[0028] The pipe fixing ring 201 consists of two arc-shaped retaining rings. The first fixing through holes 2011 are provided on the upper and lower sides of the arc-shaped retaining rings, and the first lifting strap hole 2012 is provided below the retaining rings.

[0029] In this embodiment, the pipe fixing ring 201 is designed with two arc-shaped retaining rings, which can be firmly fixed to the pipe of the hanger 1. The connection is ensured by bolts and the first fixing through hole 2011, thus ensuring the reliability of the overall hoisting.

[0030] The reinforcing bar fixing ring 203 is a notched retaining ring. Second fixing through holes 2031 are provided on the two side walls of the reinforcing bar fixing ring 203, and a second lifting strap hole 2032 is provided on the top of one long side wall of the reinforcing bar fixing ring 203.

[0031] In this embodiment, the rebar fixing ring 203 can be easily and quickly installed and removed from the rebar through the notched snap ring, and can be tightly fixed to the rebar by bolts in conjunction with the second fixing through hole 2031, reducing the risk of slippage and displacement.

[0032] The lifting sling 202 is equipped with lifting rings at both ends. The two lifting rings of the lifting sling 202 are respectively installed in the first lifting sling hole 2012 and the second lifting sling hole 2032. The lifting sling 202 connects the lifting pipe fixing ring 201 and the reinforcing bar fixing ring 203. The width of the first lifting sling hole 2012 and the second lifting sling hole 2032 is the same as the width of the lifting sling 202.

[0033] In this embodiment, the lifting sling 202 serves as a flexible connector, with lifting rings at both ends installed in the first lifting sling hole 2012 and the second lifting sling hole 2032. This makes the lifting process more stable and protects the integrity of the reinforcing cage structure. At the same time, the width of the first lifting sling hole 2012 and the second lifting sling hole 2032 is the same as the width of the lifting sling 202, which ensures the matching and tightness of the installation and prevents the lifting sling 202 from sliding or shifting in the hole, further improving the stability of the lifting operation.

[0034] In this embodiment, by combining the lifting pipe fixing ring 201, the lifting strap 202, and the rebar fixing ring 203, the lifting pipe fixing ring 201, compared to commonly used fixing rings, can adapt to the shape of the rebar cage and distribute the load, achieving a uniform load distribution. This reduces the number of required lifting points, lowers the risk of local stress concentration, and effectively prevents deformation or damage to the structure of the lifting frame 1. At the same time, by cooperating with the lifting strap 202, a flexible connection system can be formed, adapting to the irregular shape of the rebar cage and evenly distributing the lifting load, effectively preventing the rebar cage from twisting or breaking during lifting, and improving the stability and safety of the lifting.

[0035] Specifically, rubber anti-slip pads are provided on both the hanging pipe fixing ring 201 and the reinforcing bar fixing ring 203.

[0036] In this embodiment, the rubber anti-slip pads provided on the pipe fixing ring 201 and the rebar fixing ring 203 can increase the friction with the surface of the pipe and the rebar, preventing slippage or detachment due to vibration or movement during hoisting, thereby improving the stability and safety of the fixation.

[0037] Specifically, the right angles of the side walls of the pipe fixing ring 201 and the steel bar fixing ring 203 are rounded.

[0038] In this embodiment, the rounded corners at the right angles of the side walls of the pipe fixing ring 201 and the rebar fixing ring 203 can eliminate sharp edges, reduce the risk of operators being scratched during installation and disassembly, and improve safety.

[0039] Specifically: the lifting rod of the gantry 1 is equipped with lifting marking points.

[0040] In this embodiment, the lifting mark points set on the lifting rod of the hanger 1 can provide operators with clear visual references, help to quickly and accurately locate the corresponding positions of the lifting device and the steel cage, reduce adjustment time and human error, thereby improving lifting efficiency and ensuring uniform force distribution.

[0041] Specifically, the hoisting device also includes two gantry cranes; and the top of the gantry 1 is provided with two sets of hoisting rings.

[0042] In this embodiment, the two sets of lifting rings at the top of the hanger 1, in conjunction with the two gantry cranes, can simplify the lifting operation process and improve the overall transfer efficiency.

[0043] The technical solution provided in this application may include the following beneficial effects: This application combines a lifting pipe fixing ring 201, a lifting strap 202, and a rebar fixing ring 203. Compared with commonly used fixing rings, the lifting pipe fixing ring 201 can adapt to the shape of the rebar cage and distribute the load evenly, thereby reducing the number of lifting points required, reducing the risk of local stress concentration, and effectively preventing deformation or damage to the structure of the lifting frame 1. At the same time, by working with the lifting strap 202, a flexible connection system can be formed to adapt to the irregular shape of the rebar cage and evenly distribute the lifting load, effectively preventing the rebar cage from twisting or breaking during lifting, and improving the stability and safety of the lifting.
