[0002] With the extensive use of steel structures in the field of construction, multiple steel beams are often strung together for hoisting in construction installation projects. However, strung together multiple steel beams can easily cause interference, collision, and knotting between the wire ropes. Moreover, when the steel beams are in place, construction workers need to manually arrange them, which takes a long time and is more dangerous to work at height.

[0003] The existing parallel steel beam string hanging device, during use, has a large wind-exposed area due to the parallel movement of multiple steel beams in the air. When the wind is strong, the swing amplitude is too large, making the force environment of the entire suspension device complex, which can easily cause safety accidents and affect the service life of the equipment. It is not conducive to the operation of construction personnel and is very inconvenient. Therefore, in view of the above situation, it is urgent to develop a parallel steel beam string hanging device to overcome the shortcomings in current practical applications.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] A hoisting mechanism, which is connected to the support plate 1 and the adjustment frame 8 respectively, and is installed in coordination with the hoisting plate 10;

[0026] Among them, the lifting mechanism includes an adjusting component and a driving component, the adjusting component includes a rotating shaft 4, a control box 5, a guide vane 6 and a control unit, the control box 5 is located on the support plate 1, and a control unit is arranged in the control box 5, the control unit is connected to the driving component, the driving component is located on the adjusting frame 8, and is connected to the lifting plate 10, the rotating shaft 4 is rotatably installed on the support plate 1, and one end of the rotating shaft 4 is connected to the control box 5, and a guide vane 6 is fixedly installed on the other end of the rotating shaft 4.

[0027] During the steel beam hoisting process, first, a support plate 1 is set up, wherein the support plate 1 can adopt a steel frame structure, and is connected to the hoisting equipment through a lifting ring 2 and a steel wire rope, wherein two nylon ropes can be wound around the steel wire rope, and the rotation directions of the two nylon ropes are opposite, and the ends are connected to the support plate 1 to prevent the support plate 1 from rotating during the hoisting process, which will not be described in detail here. Then, through the set hoisting plate 10 and the hoisting rope 13, several steel beam bodies 14 that need to be hoisted can be connected to the hoisting rope 13, thereby realizing the hoisting of the steel beam body 14, which can improve the efficiency of the hoisting work. During the aerial hoisting of the steel beam body 14, when encountering a large wind speed, through the set guide vane 6, wherein the guide vane 6 can adopt a combination of a rod-shaped structure and a plate-shaped structure, and is in a parallel state with the hoisting plate 10 and the steel beam body 14, under the action of wind force, the guide vane 6 can be blown to rotate, and the rotating shaft 4 can be driven to rotate in the support plate 1 and the control box 5 Rotate, at this time, the control unit can be driven to work, when the control unit is in working state, the driving component can be put into work, so as to drive the hanging plate 10 to rotate a certain angle on the adjusting frame 8 through the connecting seat 12 until it is parallel to the guide blade 6 again. At this time, the hanging plate 10 and the steel beam body 14 are parallel to the wind direction, so that the wind-receiving area of ​​the hanging plate 10 and the steel beam body 14 can be reduced, wherein the guide blade 6 can also be connected to an external electronic device for manually controlling the steering of the guide blade 6, so that when the steel beam body 14 on the hanging plate 10 is removed, the steel beam body 14 can be quickly and accurately put into place, saving time, and no more details are given here, and a number of through holes can be provided on the adjusting frame 8, which can also reduce the wind-receiving area of ​​the overall device, so as to avoid excessive swinging of the steel beam body 14 in the case of strong wind, affecting the hanging work, which is conducive to reducing the probability of safety accidents, and can extend the service life of the equipment, providing convenience for construction personnel, and worthy of promotion.

[0028] In one embodiment of the present invention, see Figure 1 and Figure 5 , the control unit comprises:

[0029] A speed limiting member 3, the speed limiting member 3 is located on the support plate 1 and is installed in cooperation with the rotating shaft 4;

[0030] An encoder 32, wherein the encoder 32 is located in the control box 5 and is also connected to the rotating shaft 4; and

[0031] The controller 7 is located on the support plate 1 and is electrically connected to the encoder 32 and the driving assembly respectively.

[0032] By setting a speed limiting component 3, wherein the speed limiting component 3 can be in the form of a combination of a flow sensor and a wear-resistant disk, the contact friction between the speed limiting component 3 and the rotating shaft 4 can be changed as the wind speed changes, thereby achieving the purpose of limiting the speed of the rotating shaft 4 and realizing smooth rotation. In addition, the rotating shaft 4 can be controlled to rotate only under a certain wind force to avoid rotating too frequently and affecting the operation of the equipment. No further details will be given here. When the rotating shaft 4 rotates, the encoder 32 can be driven to work, and through the control and signal transmission of the controller 7, the drive component can be moved a distance in the specified direction until the lifting plate 10 and the steel beam body 14 are driven to rotate until they are parallel to the guide blade 6 again.

[0033] In one embodiment of the present invention, see Figure 1-3 , the driving assembly comprises:

[0034] A stepper motor 16, wherein the stepper motor 16 is located on the adjustment frame 8 and is electrically connected to the controller 7;

[0035] A threaded rod 15, one end of which is connected to the output end of the stepping motor 16, and the other end of which is rotatably connected to the adjustment frame 8;

[0036] A driving member 17, wherein the driving member 17 is threadedly connected to the threaded rod 15 through a threaded hole 22, the threaded hole 22 is formed on the driving member 17, and the driving member 17 is also slidably connected to the adjustment frame 8 through a guide plate 18;

[0037] a rack 19, the rack 19 being located on the driving member 17; and

[0038] A rotating shaft 20 , one end of which is rotatably connected to the adjusting frame 8 and connected to the connecting seat 12 , the other end of which is installed through the control box 5 , and the rotating shaft 20 is also meshedly connected to the rack 19 via a gear 21 .

[0039] When the encoder 32 is put into operation, the stepper motor 16 can be controlled by the controller 7 to start working, and can drive the two sets of threaded rods 15 to rotate synchronously, and the rotation speed is equal and the rotation direction is the same. When the threaded rod 15 rotates, the driving member 17 can be driven to move through the action of the threaded transmission, and the two sets of driving members 17 can be made to move horizontally in opposite directions through the limiting guiding action of the guide plate 18. Among them, the driving member 17 can be in the form of a square body. When the driving member 17 moves, it can drive the rack 19 to move synchronously, and through the action of the tooth meshing transmission, it can drive the rotating shaft 20 and the gear 21 to rotate on the adjusting frame 8. By controlling the movement square and movement distance of the driving member 17, the rotation angle of the rotating shaft 20 can be controlled. When the rotating shaft 20 rotates, it can drive the hanging plate 10 and the steel beam body 14 to rotate synchronously, thereby achieving the purpose of adjusting the steel beam body 14 to reduce the area of ​​several steel beam bodies 14 in contact with wind force.

[0040] In one embodiment of the present invention, see Figure 5 , further comprising: a first blade 33, wherein the first blade 33 is located in the control box 5 and connected to the rotating shaft 4;

[0041] a second blade 35 connected to the rotating shaft 20; and

[0042] The sensor 34 is located on the first blade 33 and the second blade 35 respectively, and is electrically connected to the stepping motor 16 .

[0043] When the rotating shaft 4 is rotated by the wind force, and the encoder 32 controls the driving assembly to drive the hanging plate 10 and the steel beam body 14 to rotate, the first blade 33 can be driven to rotate, and when the rotating shaft 4 stops, the first blade 33 also stops. At this time, the driving assembly slowly drives the hanging plate 10 and the steel beam body 14 to rotate, and can drive the second blade 35 to rotate synchronously. Under the program control of the encoder 32, the hanging plate 10 and the steel beam body 14 stop after rotating a specific angle. Through the set sensor 34, where the sensor 34 can be in the form of a photoelectric sensor, when the first blade 33 and the second blade 35 are in the vertically facing position, the sensor 34 starts working, thereby controlling the stepping motor 16 to stop, so as to further improve the safety and stability of the equipment operation under the program control of the encoder 32, play a role of double protection, avoid the equipment from failing to achieve the purpose of adjustment, and under the action of the structure of meshing between the teeth, the rotating hanging plate 10 and the steel beam body 14 can be stably stopped at the specified position.

[0044] In one embodiment of the present invention, see Figure 2-4 , further comprising: an active cavity 31, wherein the active cavity 31 is opened on the driving member 17;

[0045] A limiting post 24, wherein the limiting post 24 is located in the active cavity 31 and is slidably connected to the active cavity 31 by clamping;

[0046] A card plate 25, one end of which is connected to the limiting column 24, and the other end of which passes through a card slot 26 and is connected to the rack 19, wherein the card slot 26 is provided on the driving member 17 and communicates with the active cavity 31; and

[0047] A protection unit is located in the active cavity 31 and connected to the limiting column 24 .

[0048] When the driving member 17 drives the rack 19 to move, the hanging plate 10 and the steel beam body 14 can be driven to rotate. When the adjustment component is adjusted, the hanging plate 10 and the steel beam body 14 are still not completely parallel to the wind direction, which will cause the hanging plate 10 and the steel beam body 14 to be affected by the wind force. There is still a situation where the hanging plate 10 and the steel beam body 14 swing greatly in the air. Therefore, the commonly set protection unit works, wherein the protection unit can be started by manual control or automatic control according to the size of the wind. After the protection unit is put into operation, the limit column 24 can move a certain distance in the active cavity 31, and By cooperating with the provided clamping plate 25 and the clamping slot 26, the limiting column 24 can be limited and guided to ensure the stability of the limiting column 24 when moving, and buffer blocks are provided at both ends of the clamping slot 26 to avoid large collisions. When the hanging plate 10 and the steel beam body 14 are still not completely parallel to the wind direction after adjustment, the hanging plate 10 can drive the gear 21 and the rotating shaft 20 to rotate a certain angle, and the rack 19 can drive the limiting column 24 to move a certain distance in the active cavity 31, so that the hanging plate 10 and the steel beam body 14 can achieve the purpose of adaptive wind direction, ensure stability during hanging, and avoid excessive force.

[0049] In one embodiment of the present invention, the protection unit comprises:

[0050] A telescopic sleeve 30, wherein the telescopic sleeve 30 is located in the active cavity 31;

[0051] An electromagnet 27, wherein the electromagnet 27 is connected to the inner wall of the telescopic sleeve 30, and a limit rod 28 is fixedly mounted on the electromagnet 27;

[0052] A magnetic plate 29, wherein the magnetic plate 29 is slidably connected to the inner wall of the telescopic sleeve 30, and the magnetic plate 29 is installed through the limiting rod 28 and is slidably connected to the limiting rod 28; and

[0053] The spring 23 has two ends connected to the magnetic plate 29 and the limiting column 24 respectively.

[0054] By means of the telescopic sleeve 30, the magnetic plate 29 can slide freely in the telescopic sleeve 30, and by means of the limit rod 28, the magnetic plate 29 can be limited to prevent it from slipping out of the telescopic sleeve 30. Under normal working conditions, the current passed into the electromagnet 27 can be increased, thereby enhancing the magnetic repulsion between the electromagnet 27 and the magnetic plate 29. Under the thrust of the magnetic plate 29, the spring 23 can be compressed. Under the elastic action of the spring 23, the movement of the limit column 24 under normal working conditions can be prevented. The magnitude of the current passed into the electromagnet 27 can be gradually reduced through manual control or automatic control according to wind force. Under the action of the reduced magnetic repulsion, the elastic force of the spring 23 is also gradually reduced, thereby allowing the limit column 24 to move a short distance in the active cavity 31.

[0055] In one embodiment of the present invention, see Figure 1 and Figure 6 , further comprising: a telescopic cylinder 37, wherein the telescopic cylinder 37 is located on the hoisting plate 10;

[0056] A sliding rod 36, which is slidably mounted on the hanging plate 10 and connected to the output end of the telescopic cylinder 37;

[0057] a fixed pulley 9, the fixed pulley 9 being rotatably connected to the hanging plate 10; and

[0058] A limiting rope 11 , one end of which is connected to the sliding rod 36 , and the other end of which is connected to the adjusting frame 8 via a fixed pulley 9 .

[0059] By starting the operation through the telescopic cylinder 37, the sliding rod 36 can be pulled or pushed to move on the hanging plate 10, so that the length of the limiting rope 11 can be changed. When the hanging plate 10 rotates, the rotation angle of the hanging plate 10 can be limited by the tension of the limiting rope 11 to improve the practicality and flexibility of the equipment. At the same time, by setting two sets of limiting ropes 11 and cooperating with the telescopic cylinder 37, the stability of the hanging plate 10 and the steel beam body 14 after adjustment can be ensured under the tension of the limiting rope 11.

[0060] In summary, during the steel beam hoisting process, the plurality of steel beam bodies 14 to be hoisted can be connected to the hoisting rope 13 through the provided hoisting plate 10 and the hoisting rope 13, thereby realizing the hoisting work of the steel beam body 14, and improving the efficiency of the hoisting work. During the aerial hoisting of the steel beam body 14, when encountering a large wind speed, the guide blades 6 are provided, wherein the guide blades 6 can be in the form of a combination of a rod-shaped structure and a plate-shaped structure, and are in a parallel state with the hoisting plate 10 and the steel beam body 14. Under the action of wind force, the guide blades 6 can be blown to rotate, and the rotating shaft 4 can be driven to rotate in the support plate 1 and the control box 5. At this time, the control unit can be driven to work. When the control unit is in the working state, the driving component can be put into operation, thereby driving the hoisting plate 10 through the connecting seat 1 2 is rotated on the adjustment frame 8 by a certain angle until it is parallel to the guide blade 6 again. At this time, the hoisting plate 10 and the steel beam body 14 are parallel to the wind direction, so that the wind-receiving area of ​​the hoisting plate 10 and the steel beam body 14 can be reduced. The guide blade 6 can also be connected to an external electronic device for manually controlling the steering of the guide blade 6, so that when the steel beam body 14 on the hoisting plate 10 is removed, the steel beam body 14 can be quickly and accurately put into place, saving time. No more details are given here. The adjustment frame 8 can be provided with a plurality of through holes, which can also reduce the wind-receiving area of ​​the overall device, so as to avoid the steel beam body 14 from swinging too much in the case of strong wind, which affects the hoisting work, is conducive to reducing the probability of safety accidents, and can extend the service life of the equipment, providing convenience for construction personnel.
