[0014] The present invention also discloses a hoisting method based on steel structure profiles, which uses the above-mentioned hoisting equipment based on steel structure profiles and includes the following steps:

[0015] S1: First, move the connection lock to the top of the steel profile through the operation of the movable support arm;

[0016] S2: Then, the connecting lock is aligned with the two ends of the steel profile by rotating the reversing member, and then the connecting lock is connected to the steel profile;

[0017] S3: The sling is used to lift the steel profile through the operation of the control box. During this process, the side of the control box away from the first side arm is counterweighted through the adaptive configuration component to reduce the weight difference on both sides of the movable support arm;

[0018] S4: The steel profile is then moved to a designated position through the operation of the movable support arm. When the connecting lock is separated from the steel profile, the end of the connecting lock away from the positioning plate is limited by the pulling unit to prevent entanglement between the connecting locks on both sides of the positioning plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting the adaptive configuration parts, the sling pulls the traction frame upward. At this time, the gravity of the steel profile acts on the weight measuring spring, and the aqueous solution inside the water storage bin will enter the casing through the connecting hose, so that the counterweight block is away from the control box. When the weight measuring spring shrinks to a certain length, the traction frame continues to move upward to drive the transition bin to move upward. The heavier the steel profile, the greater the extrusion force on the weight measuring spring, the greater the deformation, and the more aqueous solution discharged from the water storage bin. In this way, the counterweight block can be farther away from the control box, so that the position of the counterweight block can be adjusted according to the weight of the steel profile, so that the weight difference on both sides of the movable support arm is small, thereby ensuring the stability of the equipment in lifting and transporting the steel profile;

[0021] 2. By setting a rotating reversing member and rotating the positioning disk, the position of the connecting lock buckle is changed so that the connecting lock buckle is aligned with the two ends of the steel profile, thereby preventing the sling from twisting when the position of the connecting lock buckle is adjusted. When the sleeve disk moves upward relative to the guide rod, the top of the pressure rod will lose its limit. At this time, the pressure rod will drive the first contact piece to move upward under the action of the elastic restoring force of the first return spring, thereby separating the first contact piece from the second contact piece, thereby closing the solenoid valve, thereby limiting the third piston rod, thereby improving the stability of the rotating shaft relative to the transition bin, preventing the steel profile from rotating relative to the sling during movement, so that steel profiles in different directions can be lifted without affecting the sling, thereby improving the stability of the steel profile during movement;

[0022] 3. By setting a pulling unit, when connecting the connecting lock to the steel profile, pull the connecting lock. At this time, the connecting lock drives the clockwork spring to reel in through the second hanging ring, the first hanging ring, and the pulling rope. After the steel profile is separated from the connecting lock, the clockwork spring will pull the pulling rope into the first connecting compartment. At this time, the connecting lock will swing away from the positioning disk to prevent entanglement between the connecting locks. At the same time, it also prevents the connecting lock of the movable support arm that is not connected to the steel profile from swinging significantly relative to the positioning disk during operation, thereby improving the safety of equipment use.

The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0034] See also Figures 1 to 8 In an embodiment of the present invention, a lifting device based on a steel structure profile includes a movable support arm 1, a control box 3 is installed at the top of the movable support arm 1, a first side arm 2 and a second side arm 501 are installed on both sides of the control box 3, a sling 4 extending to the outside of the control box 3 and located above the first side arm 2 is arranged inside the control box 3, a traction frame 505 is installed at the bottom end of the sling 4, an adaptive configuration member is arranged on the upper part of the movable support arm 1, the sling 4 is connected to a transition bin 528 through the adaptive configuration member, a rotating coupling 526 extending to the bottom of the transition bin 528 is rotatably connected inside the transition bin 528 through a bearing, a positioning disk 506 located below the transition bin 528 is installed at the bottom end of the rotating coupling 526, a rotating reversing member is arranged on the outside of the transition bin 528, connecting blocks 507 are installed on both sides of the positioning disk 506, a connecting lock 509 is installed on the connecting block 507, and a pulling unit connected to the connecting lock 509 is arranged on the side of the connecting block 507 away from the positioning disk 506.

[0035] In this embodiment: when the steel profile is hoisted and transported, the connecting lock 509 is first moved above the steel profile through the operation of the movable support arm 1, and then the connecting lock 509 is aligned with the two ends of the steel profile by rotating the reversing member, and then the connecting lock 509 is connected to the steel profile, and then the sling 4 is used to lift the steel profile through the operation of the control box 3. In this process, the side of the control box 3 away from the first side arm 2 is counterweighted by the adaptive configuration part to reduce the weight difference on both sides of the movable support arm 1, and then the steel profile is moved to the specified position through the operation of the movable support arm 1. When the connecting lock 509 is separated from the steel profile, the end of the connecting lock 509 away from the positioning plate 506 is limited by the pulling unit to prevent the connecting locks 509 on both sides of the positioning plate 506 from being entangled. At the same time, it also prevents the connecting lock 509 that is not connected to the steel profile from swinging significantly relative to the positioning plate 506 during the operation of the movable support arm 1, thereby improving the safety of equipment use.

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The adaptive configuration includes guide grooves 502 opened on both sides of the second side arm 501, and a rotating roller 514 is slidably connected inside the guide groove 502. A connecting plate 515 is installed on the side of the rotating roller 514 away from the second side arm 501. A counterweight 503 is arranged on the outer side of the connecting plate 515. A first piston rod 511 is installed on the connecting plate 515. A sleeve 513 connected to the first side arm 2 is sleeved on the first piston rod 511. A positioning block 518 is installed at the bottom of the traction frame 505. Guide rods 521 are installed on both sides of the transition bin 528. A top plate 525 is installed on the top of the guide rod 521, and a sleeve 516 slidably connected to the outside of the guide rod 521 is provided at the bottom of the positioning block 518. A water storage tank 512 is installed on the top of the top plate 525. A second piston rod 520 extending to the bottom of the top plate 525 and connected to the positioning block 518 is inserted into the water storage tank 512. A weight measuring spring 519 connected to the bottom of the top plate 525 and located on the outside of the second piston rod 520 is installed on the top of the positioning block 518. A connecting hose 504 connected to the sleeve 513 is installed on the top of the water storage tank 512.

[0037] In this embodiment, when the sling 4 pulls the traction frame 505 upward, the traction frame 505 drives the positioning block 518 and the sleeve 516 to move upward. At this time, the transition bin 528 is subjected to the gravity of the steel profile, so that the sleeve 516 moves upward relative to the guide rod 521, so that the second piston rod 520 squeezes the aqueous solution inside the water storage bin 512. At this time, the gravity of the steel profile acts on the weight measuring spring 519, and the aqueous solution inside the water storage bin 512 will enter the sleeve 513 through the connecting hose 504, so as to push the first piston rod 511 to move toward the second side arm 501 away from one end of the control box 3, thereby The counterweight 503 is moved away from the control box 3. When the weighing spring 519 shrinks to a certain length, the traction frame 505 continues to move upward to drive the transition bin 528 to move upward, so as to lift the steel profile fixed by the connecting lock 509. The heavier the steel profile, the greater the extrusion force on the weighing spring 519, the greater the deformation generated, and the more aqueous solution discharged from the water storage tank 512. In this way, the counterweight 503 can be moved farther away from the control box 3, and the position of the counterweight 503 can be adjusted according to the weight of the steel profile, so that the weight difference on both sides of the movable support arm 1 is smaller, thereby ensuring the stability of the equipment in lifting and transporting the steel profile.

[0038] Please refer to Figure 4 The sleeve 516 is provided with a through hole that matches the guide rod 521 , and the width of the inner side of the traction frame 505 is greater than the width of the water storage bin 512 .

[0039] In this embodiment: this structure is provided to prevent friction between the water storage bin 512 and the traction frame 505 when the sling 4 drives the traction frame 505 to move upward, thereby improving the smoothness of the movement of the sleeve 516 relative to the guide rod 521.

[0040] Please refer to Figure 3 , Figure 5 , Figure 6 The rotary reversing member includes a rotating disk 532 mounted on the top of the rotating shaft 526 and located inside the transition chamber 528, an eccentric connecting pin 534 is mounted on the top of the rotating disk 532, and a straight groove block 533 is sleeved on the outer side of the eccentric connecting pin 534. A piston sleeve block 530 staggered with the guide rod 521 is mounted on the outer wall of the transition chamber 528, and a third piston rod 536 extending to the inside of the piston sleeve block 530 is mounted on the outer wall of the straight groove block 533. An electromagnetic valve 535 is mounted on the end of the piston sleeve block 530 away from the transition chamber 528, and a bellows 531 is mounted on the end of the solenoid valve 535 away from the piston sleeve block 530. The end of the bellows 531 away from the electromagnetic valve 535 Limiting rods 538 slidingly connected to the piston sleeve block 530 are installed on both sides, and a second return spring 537 connected to the piston sleeve block 530 and located on the outside of the limiting rod 538 is arranged on the bellows expansion tube 531, and a second connecting chamber 517 located on the outside of the rotating shaft 526 is installed at the bottom of the limiting rod 538, and a pressure rod 529 is inserted at the top of the second connecting chamber 517, and a first return spring 527 connected to the second connecting chamber 517 is arranged on the pressure rod 529, and a first contact piece 539 located inside the second connecting chamber 517 is installed at the bottom of the pressure rod 529, and a second contact piece 540 located below the first contact piece 539 is installed inside the second connecting chamber 517.

[0041] In this embodiment, when the positioning plate 506 is moved to the top of the steel profile, the positioning plate 506 is rotated to change the position of the connecting lock 509 so that the connecting lock 509 is aligned with the two ends of the steel profile, thereby preventing the sling 4 from twisting when the position of the connecting lock 509 is adjusted. In this process, the turntable 532 drives the straight groove block 533 to move the third piston rod 536 through the eccentric connecting pin 534, so that the aqueous solution inside the piston sleeve block 530 is injected into the corrugated telescopic tube 531 through the electromagnetic valve 535, and then the connecting lock 509 can be connected to the steel profile. When the sleeve 516 is relative to the guide rod 52 When the first contact piece 539 is moved upward, the top of the pressure rod 529 will lose the limit position. At this time, the pressure rod 529 will drive the first contact piece 539 to move upward under the action of the elastic restoring force of the first return spring 527, so as to separate the first contact piece 539 from the second contact piece 540, so that the electromagnetic valve 535 is closed, so as to limit the third piston rod 536, thereby improving the stability of the rotating shaft 526 relative to the transition chamber 528, preventing the steel profile from rotating relative to the sling 4 during the movement, so that the steel profile in different directions can be lifted without affecting the sling 4, so as to improve the stability of the steel profile during the movement.

[0042] Please refer to Figure 6 The first contact piece 539 is electrically connected to the external power supply through a wire, and the second contact piece 540 is electrically connected to the solenoid valve 535 through a wire.

[0043] In this embodiment, by providing this structure, the electromagnetic valve 535 is in an open state when the first contact piece 539 contacts the second contact piece 540 , so as to accurately control the opening and closing of the electromagnetic valve 535 .

[0044] Please refer to Figure 6 The center of the cross section of the eccentric connecting pin 534 is misaligned with the center of the rotating disk 532 , and a through hole matching the third piston rod 536 is provided on the transition chamber 528 .

[0045] In this embodiment, by providing this structure, when the rotating disk 532 rotates, the eccentric connecting pin 534 and the straight groove block 533 drive the third piston rod 536 to move horizontally.

[0046] Please refer to Figure 6 , the inner wall diameter of the second connecting chamber 517 is larger than the diameter of the rotating shaft 526.

[0047] In this embodiment: this structure is provided to prevent friction between the rotating shaft 526 and the second connecting compartment 517, thereby improving the smoothness of the rotation of the rotating shaft 526.

[0048] Please refer to Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 8 The pulling unit includes an extension rod 508 installed on the connecting block 507, and the end of the extension rod 508 away from the connecting block 507 is connected to the first connecting warehouse 510, and a clockwork spring 541 is installed inside the first connecting warehouse 510. One end of the clockwork spring 541 is connected to a pulling rope 522 extending to the outside of the first connecting warehouse 510, and one end of the pulling rope 522 is installed with a first hanging ring 523, and a second hanging ring 524 connected to the first hanging ring 523 is installed on the connecting lock buckle 509.

[0049] In this embodiment: when connecting the connecting lock 509 to the steel profile, the connecting lock 509 is pulled. At this time, the connecting lock 509 drives the clockwork spring 541 to be retracted through the second hanging ring 524, the first hanging ring 523, and the pulling rope 522. After the steel profile is separated from the connecting lock 509, the clockwork spring 541 will pull the pulling rope 522 to retract into the first connecting compartment 510. At this time, the connecting lock 509 will swing in the direction away from the positioning disk 506, so as to prevent the connecting locks 509 from being entangled. At the same time, it also prevents the connecting lock 509 that is not connected to the steel profile from swinging significantly relative to the positioning disk 506 when the movable support arm 1 is in operation, thereby improving the safety of equipment use.

[0050] Please refer to Figure 7 , Figure 8 The two sides of the first connecting compartment 510 are rotatably connected to the extension rod 508 through bearings.

[0051] In this embodiment: by providing this structure, the swing range of the pull rope 522 is increased, so that the pull rope 522 can move along with the connection buckle 509.

[0052] In combination with the above-mentioned steel structure profile-based hoisting equipment, a steel structure profile-based hoisting method is provided below, which specifically includes the following steps:

[0053] S1: First, the connection lock 509 is moved above the steel profile by operating the movable support arm 1;

[0054] S2: Rotate the positioning plate 506 to change the position of the connection lock 509 so that the connection lock 509 is aligned with the two ends of the steel profile, so as to prevent the sling 4 from twisting when the position of the connection lock 509 is adjusted. In this process, the turntable 532 drives the straight groove block 533 to move the third piston rod 536 through the eccentric connecting pin 534, so that the aqueous solution inside the piston sleeve block 530 is injected into the bellows 531 through the solenoid valve 535, and then the connection lock 509 can be connected to the steel profile;

[0055] S3: When the sling 4 pulls the traction frame 505 upward, the traction frame 505 drives the positioning block 518 and the sleeve 516 to move upward. At this time, the transition chamber 528 is subjected to the gravity of the steel profile, so that the sleeve 516 moves upward relative to the guide rod 521, so that the second piston rod 520 squeezes the aqueous solution inside the water storage tank 512. At this time, the gravity of the steel profile acts on the weight measuring spring 519, and the aqueous solution inside the water storage tank 512 will enter the sleeve 513 through the connecting hose 504, so as to push the first piston rod 511 to move toward the second side arm 501 away from one end of the control box 3, thereby The counterweight block 503 is moved away from the control box 3. When the weight measuring spring 519 shrinks to a certain length, the traction frame 505 continues to move upward to drive the transition bin 528 to move upward, so as to lift the steel profile fixed by the connecting lock 509. The heavier the steel profile, the greater the extrusion force on the weight measuring spring 519, the greater the deformation amount generated, and the more aqueous solution discharged from the water storage bin 512. In this way, the counterweight block 503 can be moved farther away from the control box 3, so that the position of the counterweight block 503 can be adjusted according to the weight of the steel profile, so that the weight difference on both sides of the movable support arm 1 is small, thereby ensuring the stability of the equipment in lifting and transporting the steel profile.

[0056] S4: When the sleeve 516 moves upward relative to the guide rod 521, the top of the pressure rod 529 will lose its limit position. At this time, the pressure rod 529 will drive the first contact piece 539 to move upward under the action of the elastic restoring force of the first return spring 527, so as to separate the first contact piece 539 from the second contact piece 540, so that the solenoid valve 535 is closed, so as to limit the third piston rod 536, thereby improving the stability of the rotating shaft 526 relative to the transition chamber 528, preventing the steel profile from rotating relative to the sling 4 during the movement, so that the steel profiles in different directions can be lifted without affecting the sling 4, so as to improve the stability of the steel profiles during the movement;

[0057] S5: Then, the steel profile is moved to a designated position through the operation of the movable support arm 1;

[0058] S6: After the steel profile is separated from the connecting lock 509, the clockwork spring 541 will pull the pull rope 522 to retract into the first connecting compartment 510. At this time, the connecting lock 509 will swing in the direction away from the positioning plate 506, so as to prevent the connecting locks 509 from being entangled. At the same time, it also prevents the connecting lock 509 of the movable support arm 1 that is not connected to the steel profile from swinging significantly relative to the positioning plate 506 during operation, thereby improving the safety of the equipment.

[0059] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
