Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and in particular to an intelligent hanger suitable for special-shaped componentized steel and steel bars and a use method thereof. Background Art

[0002] Special-shaped modular steel and steel bars refer to steel with specific shapes and sizes produced by prefabrication factories. Since they are prefabricated parts, they have been processed into the required shapes during production and can be used directly on the construction site without a lot of processing. Special-shaped modular steel and steel bars are usually large pieces, so when they are transported to the construction site for construction, they often need to be hoisted using a hanger to achieve hoisting.

[0003] Although special-shaped steel and steel bars can enhance the flexibility and functionality of the structure, they also put forward higher requirements for lifting equipment. Traditional hangers are often designed for components with standardized and simple shapes, which makes them lack adaptability and flexibility when facing complex and changing shapes, resulting in low lifting efficiency and increased safety hazards.

[0004] In addition, the hanger will be affected by wind when lifting special-shaped modular steel and steel bars. Unlike traditional standard steel, special-shaped modular steel and steel bars may produce uneven airflow when affected by wind, causing some areas to bear greater wind pressure. This uneven wind force will make the special-shaped modular steel and steel bars more prone to tilting. Existing hangers usually do not consider the dynamic behavior of special-shaped modular steel and steel bars under wind, making it difficult to adapt quickly, increasing the risk of accidents during the lifting process, and making it difficult to install special-shaped modular steel and steel bars under wind.

[0029] The following will be combined with the attached Figure 1 -Attached Figure 7 The present invention is further illustrated by the following embodiments.

[0030] This embodiment discloses an intelligent hanger suitable for special-shaped componentized steel and steel bars and a method of use.

[0031] The intelligent hanger applicable to special-shaped component steel and steel bars includes a hanger overall frame composed of several longitudinal beams 2 and several cross beams 1. The longitudinal beams 2 are parallel to each other, the cross beams 1 are parallel to each other, the longitudinal beams 2 and the cross beams 1 are vertically fixedly connected to each other, and the length of the longitudinal beams 2 is greater than the length of the cross beams 1. In this embodiment, the number of longitudinal beams 2 is two, the number of cross beams 1 is three, and the three cross beams 1 are vertically connected between two longitudinal beams 2 that are parallel to each other, and the longitudinal beams 2 and the cross beams 1 are located at the same height. In addition, the three cross beams 1 are evenly spaced, the spacing between the first and third cross beams 1 is less than the length of the longitudinal beams 2, and the two ends of the second cross beam 1 are respectively connected to the midpoints of the two longitudinal beams 2. Finally, a square-shaped hanger overall frame is formed between the longitudinal beams 2 and the cross beams 1. In the use state, the hanger overall frame is square-shaped when viewed from above.

[0032] The overall frame of the hanger needs to be connected to the hook of the lifting equipment during use. For this purpose, the four corners of the top of the overall frame of the hanger are provided with first lifting ears 10. Specifically, four first lifting ears 10 are respectively provided in groups of two on the top of the two longitudinal beams 2, and the first lifting ears 10 are located at the top of the intersection of the longitudinal beams 2 and the cross beams 1. Furthermore, each first lifting ear 10 is connected to a first bow shackle 18, and the first bow shackle 18 is connected to a first steel wire rope 11. The first lifting ear 10 is connected to the hook of the lifting equipment through the first bow shackle 18 and the first steel wire rope 11, so that the lifting equipment can finally lift the overall frame of the hanger smoothly.

[0033] Several suspension beams 3 are also arranged between the two longitudinal beams 2. The several suspension beams 3 are parallel to each other and are vertically connected to the longitudinal beams 2. The heights of the several suspension beams 3 are higher than the heights of the longitudinal beams 2, so that the several suspension beams 3 are located above the longitudinal beams 2 and are connected to the tops of the longitudinal beams 2. Furthermore, the length of each suspension beam 3 is greater than the spacing between the two longitudinal beams 2, so that after each suspension beam 3 is connected to the two longitudinal beams 2, both ends of the suspension beam 3 can extend to the outside of the longitudinal beams 2. A plurality of second lifting ears 8 are arranged at the bottom of the suspension beam 3 along the length direction. The second suspension ears 8 are connected with U-shaped basket bolts 20, second steel wire ropes 15 and second bow-shaped shackles 19 in sequence. The second bow-shaped shackles 19 are connected to the special-shaped component steel and the steel bar 14, so that the hoisting frame can simultaneously hoist the special-shaped component steel and the steel bar 14 after hoisting, so as to carry out hoisting.

[0034] In this embodiment, the three hanging beams 3 are divided into a first hanging beam, a second hanging beam and a third hanging beam with increasing lengths in the arrangement direction, wherein the first hanging beam and the second hanging beam are movable hanging beams, both of which are movably connected to the two longitudinal beams 2, and the third hanging beam is a fixed hanging beam, which is fixedly connected to the two longitudinal beams 2, and the spacing between the first hanging beam and the second hanging beam is smaller than the spacing between the second hanging beam and the third hanging beam. Furthermore, a three-way jack 12 is connected between the movable hanging beam and the longitudinal beam 2, the base of the three-way jack 12 is fixedly connected to the top of the longitudinal beam 2, and the movable end of the three-way jack 12 is fixedly connected to the bottom of the movable hanging beam, so that the movable hanging beam can be adjusted in three directions under the control of the three-way jack 12, solving the problem that the hanger lacks adaptability and flexibility when facing the complex and changeable shapes of different special-shaped component steel and steel bars 14, resulting in low hoisting efficiency and increased safety hazards.

[0035] The hanger is also provided with a roll adjustment system, which includes a data acquisition module, a data processing module and an execution module. The data acquisition module includes four inclination sensors 16 and multiple cable force sensors 17. The four inclination sensors 16 are arranged at the four corners of the bottom of the special-shaped component steel and the steel bar 14. The multiple cable force sensors 17 are arranged one by one on multiple second steel wire ropes 15. The data acquisition module collects the inclination values ​​of the special-shaped component steel and the steel bar 14 through the inclination sensors 16, and collects the cable force values ​​of the second steel wire ropes 15 through the cable force sensors 17. The data processing module is the control element 9, and the execution module is the three-way jack 12. The control element 9 is arranged at the top of the overall frame of the hanger. The control element 9 includes a data cache unit and a data processing unit. The control element 9 stores the inclination value transmitted by the inclination sensor 16 and the cable force value transmitted by the cable force sensor 17 through the data cache unit. The control element 9 calculates the actions that the three-way jack 12 as the execution module needs to perform through the data processing unit. These actions need to keep the special-shaped component steel and the steel bar 14 horizontal and make the cable forces of the multiple second steel wire ropes 15 relatively balanced. Finally, by setting up a roll adjustment system, the hanger of the present invention can monitor the dynamic behavior of the special-shaped component steel and the steel bar 14 under the action of wind, achieve rapid adaptation, reduce the risk of accidents during the hoisting process, and make the special-shaped component steel and the steel bar 14 easy to install under the action of wind.

[0036] The connection between the base of the three-way jack 12 and the longitudinal beam 2, the connection between the movable end of the three-way jack 12 and the movable hanging beam, and the connection between the fixed hanging beam and the longitudinal beam 2 are all realized by the precision-rolled threaded steel bar 6 and the nut 5 threadedly connected to the precision-rolled threaded steel bar 6. In addition, in order to improve the lateral limiting effect of the hanging beam 3 on the two longitudinal beams 2, the bottom of the base of the three-way jack 12 and the bottom of the third hanging beam are both provided with a stopper 4, and the stopper 4 abuts against both sides of the longitudinal beam 2 in the width direction.

[0037] The method for using the intelligent hanger for special-shaped componentized steel and steel bars includes the following steps:

[0038] The lifting equipment will lift the hanger to the top of the special-shaped component steel and steel bar 14, then adjust the position of the movable hanging beam on the hanger according to the size and shape of the special-shaped component steel and steel bar 14, and then connect the hanging beam 3 with the special-shaped component steel and steel bar 14 for lifting, and then monitor the tilt of the special-shaped component steel and steel bar 14 and the tension of the second steel wire rope 15 during the lifting process, and then adjust the position of the movable hanging beam according to the monitoring data. It should be noted that the three-way jack 12 needs to be lifted to a certain height in advance before lifting, so that the movable hanging beam has space for lowering and adjustment.

[0039] To sum up, the specific process of roll adjustment is as follows:

[0040] Step 1: Lift the intelligent hanger with a lifting device and place it in a position suitable for workers to operate just above the tower column component steel and steel bar segment. Adjust the coordination of the hanging beam 3, the three-way jack 12, and the second lifting lug 8. Connect the hanger with the special-shaped component steel and steel bar 14 through the second bow-shaped shackle 19 and the U-shaped basket bolt 20. During the lifting, the three-way jack 12 is lifted to a certain height, and then the special-shaped component steel and steel bar 14 are lifted and moved in the air.

[0041] Step 2: The center of gravity of the segment and the hanger is offset, and the control element 9 controls the hydraulic oil inside the three-way jack 12 to work;

[0042] The working steps of control element 9 are as follows:

[0043] S1, obtaining the value of the tilt sensor 16, including a data buffer unit and a data processing unit;

[0044] S11, receiving the signal of the inclination sensor 16 through the digital input module, obtaining the inclination value transmitted by each inclination sensor 16, and storing it in the data cache unit;

[0045] S12, the data processing unit obtains the data set of the inclination angle in the data cache unit, and further determines to obtain the inclination angle value of the outermost jack side of the segment and the corresponding inclination sensor 16 number;

[0046] S2, obtaining the force value, obtaining the signal of the cable force sensor 17, performing signal translation, and obtaining the cable force magnitude;

[0047] S3, respectively obtain the values ​​of S1 offset angle and S2 cable force, calculate the value at which the bottom of the segment reaches horizontal level and the value at which the cable forces of the steel wire ropes 15 of each hanging beam reach a relatively balanced value when the bottom of the segment is ensured to be horizontal:

[0048] Step three, the control element 9 controls the hydraulic cylinder of the three-way jack 12 to perform a contraction action, which drives the hanging beam to move in three directions, and simultaneously drives the second steel wire rope 15 to contract, until the inductive offset sensor in the control element 9 senses that the center of gravity of the special-shaped component steel and steel bar 14 and the hanger are in the same vertical direction, the bottom of the segment is horizontal, and the tension of the hanging beam steel wire rope reaches a relative balance.

[0049] The above are all preferred embodiments of the present invention, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
