Description

Technical Field

[0001] This invention relates to the field of steel structure lifting equipment technology, and in particular to a hoisting structure for the integral casting construction of multi-story industrial plants. Background Technology

[0002] In actual construction of multi-story industrial plants, with the maturity of automated steel structure formwork technology, plants typically use liftable formwork for support and adjustment, facilitating the erection of steel I-beams. Subsequently, the main structure of the plant is poured as a whole. The installation quality of the steel I-beams directly affects the subsequent pouring quality and the safety of the steel structure joints. Currently, the operational standards for hoisting structures used in the overall pouring construction of multi-story industrial plants are not ideal. Workers often encounter cumbersome formwork adjustments during I-beam installation, especially for large-span I-beams, requiring multiple repositioning adjustments. Fine-tuning is necessary to align the connection node holes with the columns. However, directly using a crane to lift the I-beam to adjust the connection node with the column, without effective support from the lower formwork, leads to problems. After dismantling the lifting equipment, the I-beam, lacking effective support, is prone to deformation due to its own weight or the release of its original elastic deformation. This causes the node to bear a large additional bending moment or shear force, and the weld seam is easily weakened by stress changes during subsequent welding. Furthermore, it makes it difficult to restrict workers from removing the lifting traction to keep the I-beam in a static load state during node installation, affecting the quality of the I-beam connection. Summary of the Invention

This structure is simple to operate and does not hinder multiple lifting and repositioning adjustments of the I-beam.

[0016] In addition, using elastic ropes in conjunction with indicator rings can easily indicate the deformation of the lifting frame, preventing the difficulty in timely detection when the lifting frame bends in the middle due to its own weight after long-term use. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described 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.

[0032] Example 1: Please refer to Figures 1 to 9 :

[0033] This invention proposes a hoisting structure for the integral casting construction of a multi-story industrial plant, including a hoisting installation component 1. Two shielding auxiliary components 2 are installed on both sides of the hoisting installation component 1. The two shielding auxiliary components 2 are installed symmetrically. The shielding auxiliary components 2 are used to shield the installation holes of the I-beam. Two lifting drive components 3 are installed on the hoisting installation component 1. Roller guide components 4 are installed on both sides of the hoisting installation component 1. Deformation indicator components 5 are installed on the hoisting installation component 1. The hoisting installation component 1 includes a lifting frame 101 and a sliding groove 1011. Two sliding grooves 1011 are opened on both sides of the lifting frame 101. The lifting frame 101 is used to lift the I-beam. Three threaded holes are provided on both sides of the lifting frame 101.

[0034] In this embodiment, the hoisting installation component 1 further includes: limiting bolts 102 and stop rods 103. Limiting bolts 102 are threaded into the threaded holes on both sides of the hoisting frame 101. The ends of the six limiting bolts 102 are tapered structures. Stop rods 103 are fixedly installed at both ends of the hoisting frame 101 by bolts, and the two stop rods 103 are L-shaped structures. The bottom ends of the two stop rods 103 are chamfered. The shielding auxiliary component 2 includes: a rotating shaft 201 and a baffle 202. The rotating shaft 201 is rotatably mounted on the hoisting frame 101. A baffle 202 is fixedly installed at the end of the rotating shaft 201, and the baffle 202 is used to shield the mounting holes of the I-beam. The shielding auxiliary component 2 also includes: a gear 203, on which a gear is fixedly installed. Gear 203; Gear 203 is aligned with the slide groove 1011 on the same side; Lifting drive component 3 includes: lifting drive frame 301 and meshing teeth 3011, the lifting drive frame 301 has a U-shaped structure; the two sides of the lifting drive frame 301 are slidably inserted into the slide groove 1011 respectively; a row of meshing teeth 3011 is fixedly installed on both sides of the lifting drive frame 301; the two rows of meshing teeth 3011 are respectively meshed with gear 203 on the same side; when the lifting drive frame 301 moves upward, the meshing teeth 3011 drive the baffle 202 to rotate and approach the I-beam; the lifting drive component 3 also includes: connecting bolt 302, connecting cable 303 and tension spring 304, the connecting bolt 302 is threadedly connected to the lifting drive frame 301; the connecting cable 303 is fixedly installed on the connecting bolt 302, and The connecting cable 303 is used to attach to the hook; one end of the tension spring 304 is fixedly connected to the inside of the lifting drive frame 301, and the other end of the tension spring 304 is fixedly connected to the inside of the lifting frame 101; the structural design of the lifting drive component 3 in conjunction with the shielding auxiliary component 2 can standardize the operation process of the workers in connecting the I-beam nodes, ensuring that the I-beam is in a static load state when connecting the I-beam nodes, and avoiding the situation where the I-beam is being lifted by the installation component 1. After the node connection is completed and the lifting traction on the I-beam is released, the I-beam will have additional internal stress at the node due to its own weight and possible elastic deformation, which will affect the quality of the bolt connection. At the same time, after subsequent welding, the large internal stress will also easily cause weld cracking. The problem is that it does not affect the multiple repositioning and adjustment of the I-beam during hoisting; the I-beam is hoisted to the top of the steel structure building and aligned with the two columns that need to be connected, and then the I-beam is lowered. The two stop rods 103 can keep the gap between the two ends of the I-beam and the two columns consistent. As the I-beam is lowered onto the formwork, it continues to be lowered. At this time, under the pull of the tension spring 304, the lifting drive frame 301 can move down, driving the meshing gear 3011 to mesh with the drive gear 203 to rotate. At this time, the gear 203 can drive the baffle 202 to flip outward, no longer blocking the installation hole of the I-beam. At this time, the I-beam is in a static load state; the installation hole of the I-beam is automatically blocked when the hoisting is under force, and the hole is automatically exposed after the static load is lowered, thus forcibly standardizing the installation operation process from a structural point of view.

[0035] In this embodiment, the roller guide 4 includes: a roller mounting frame 401 and guide wheels 402. The roller mounting frame 401 is fixedly mounted on the lifting frame 101 by bolts; a connecting cable 303 passes through the roller mounting frame 401; two guide wheels 402 are rotatably mounted on the roller mounting frame 401; the roller guide 4 also includes: a limiting groove 4021, with limiting grooves 4021 respectively opened on the two guide wheels 402, and the limiting grooves 4021 are annular grooves; the connecting cable 303 rolls against the two guide wheels 402, and the connecting cable 303 is located between the two limiting grooves 4021; in the actual H-beam hoisting operation, if the distance between the two columns exceeds the allowable deviation of the specification, even if the deviation is small... According to construction specifications, the columns also need to be recalibrated. However, in order to facilitate the connection of nodes, many workers directly connect one end of the I-beam to the column and then use a crane to pull the I-beam to connect to another column. This further causes changes in the internal stress of the building structure and affects safety. Construction supervisors have difficulty monitoring such non-standard operation sequences and construction methods in real time. Even if the guide wheel 402 reduces the drag of the connecting cable 303, if it is pulled laterally, it will still cause the baffle 202 to flip and block the installation hole of the I-beam. The roller guide 4 and the lifting drive 3 work together to control the blocking of the installation hole of the I-beam when it is pulled laterally, preventing illegal forced alignment from causing the internal stress of the structure to exceed the standard.

[0036] In Example 2, based on Example 1, the deformation indicator 5 includes: an indicator ring 501 and an elastic rope 502. The indicator ring 501 is fixedly installed in the middle of the lifting frame 101; both ends of the elastic rope 502 are fixedly installed on the lifting frame 101; there is a gap between the elastic rope 502 and the lifting frame 101; the elastic rope 502 passes through the indicator ring 501, and the elastic rope 502 and the indicator ring 501 are concentric; the deformation indicator 5 also includes: a protective cover 503. Two protective covers 503 are fixedly installed on the lifting frame 101, and the two protective covers 503 are located on both sides of the indicator ring 501; the protective covers 503 are located outside the elastic rope 502; the use of the elastic rope 502 in conjunction with the indicator ring 501 can facilitate the indication of the deformation of the lifting frame 101, avoiding the problem that it is difficult to know in time when the middle of the lifting frame 101 bends under its own weight due to long-term use. This structure can provide intuitive indication without the need for cumbersome inspection using tools such as rulers.

[0037] The working principle of this embodiment is as follows: When hoisting the I-beam, the lifting frame 101 is first inserted into the I-beam, and the two stop rods 103 are also inserted into both ends of the I-beam for limiting. Then, the limit bolts 102 are rotated forward and inserted into the I-beam. The ends of the limit bolts 102 stop the I-beam, ensuring stability during the hoisting process. Subsequently, the connecting cable 303 is attached to the hook, and the I-beam is hoisted by two cranes. The I-beam is then hoisted onto the steel structure building and aligned with the two columns to be connected. The I-beam is then lowered. The two stop rods 103 maintain a consistent gap between the two ends of the I-beam and the two columns. When lowering the I-beam onto the formwork, continue lowering it. At this point, the tension spring 304 pulls the lifting drive frame 301 downwards, causing the meshing gear 3011 to engage with the drive gear 203 and rotate. The gear 203 then causes the baffle 202 to flip outwards, no longer obstructing the mounting holes of the I-beam. The I-beam is now under static load. Workers can fine-tune the formwork support system or use a crane to lift the I-beam again to adjust its position before lowering it down. After lowering, the baffle 202 will not obstruct the mounting holes. The position can be adjusted by moving the I-beam or by adding shims to the brackets to level it. This allows for flexible lifting and adjustment work. Until the connecting holes of the I-beam are aligned with the connecting holes of the column, bolts can be inserted normally for node connection. However, when the I-beam is in a lifting state, the connecting cable 303 is pulled upward and taut, which will lift the lifting drive frame 301 upward, causing the meshing gear 3011 to mesh with the drive gear 203 and rotate. At this time, the gear 203 can drive the baffle 202 to flip inward, blocking the installation holes of the I-beam, ensuring that node connection work cannot be performed when the I-beam is in a non-static load state. When fine-tuning the I-beam, it is necessary to adjust it through the formwork to ensure that the stress at the node of the I-beam is stable and meets the installation specifications when the concrete is poured later. If the connecting cable 303 is pulled towards the end of the I-beam, the guide wheel 402 can roll to reduce resistance and pull the lifting drive frame 301 upward. This will also drive the meshing gear 3011 to mesh with the drive gear 203 and rotate. At this time, the gear 203 can drive the baffle 202 to flip inward, blocking the installation holes of the I-beam and preventing the I-beam from being pulled. After the I-beam nodes are connected, the limit bolts 102 can be rotated and removed. After the I-beam is released, the lifting frame 101 can be lifted by the crane and separated from the I-beam to complete the dismantling of this hoisting structure. Then, the formwork can be laid on the installed I-beam for pouring construction.

[0038] When the lifting frame 101 is in use and bends in the middle, the elastic rope 502 remains straight under its own elastic force. At this time, the two ends of the elastic rope 502 are connected to the two ends of the lifting frame 101. The bending of the middle of the lifting frame will cause the indicator ring 501 to deform and shift with the lifting frame. At this time, the middle of the elastic rope 502 will be close to the indicator ring 501, indicating to the staff that the lifting frame 101 is bent and needs to be straightened in time. The integrated deformation indicator can visually monitor the bending deformation of the lifting frame 101 without tools, solving the problem of easy deformation of the lifting frame 101 after long-term use and the cumbersome inspection.
