Description

Technical Field

[0001] This utility model relates to the field of steel beam hoisting technology, and more specifically, to a tool for hoisting building steel beams. Background Technology

[0002] Steel beam hoisting refers to the process in steel structure construction, such as factories, office buildings, bridges, stadiums, etc., where cranes (tower cranes, truck cranes, crawler cranes, etc.), lifting tools (lifting ropes, balance beams, special lifting tools, etc.) and auxiliary equipment are used to lift prefabricated or on-site processed steel beams (H-beams, box beams, I-beams, etc.) from the storage site, adjust their posture, transport them at high altitude, and precisely connect them to the steel columns or nodes of already installed steel beams, and then fix them with bolts and welds to form an integral structure.

[0003] Currently, the lifting equipment used for hoisting steel beams is the lifting rope. When the steel beam is lifted, the lifting rope and the steel beam form a triangle. When the angle between the lifting rope and the steel beam is between 60° and 90°, the hoisting state is relatively stable. However, the existing lifting ropes cannot be adjusted according to the length of the steel beam. When the steel beam is long, the angle between the lifting rope and the steel beam is small, which can easily cause instability in the hoisting of the steel beam. The lifting rope needs to be replaced, and the adaptability is poor. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a building steel beam hoisting tool to solve the problems that the existing hoisting rope cannot be adjusted according to the length of the steel beam, and when the steel beam is long, the included angle between the hoisting rope and the steel beam is small, which easily causes instability in the hoisting of the steel beam, requiring the replacement of the hoisting rope and having poor adaptability.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a steel beam hoisting tool, including a steel beam hanger; a hoisting rope adjustment assembly, on which two symmetrical suspension slides are provided, the hoisting rope adjustment assembly being used to adjust the distance between the two suspension slides; two first lifting lugs, the two first lifting lugs being respectively fixedly connected to the bottom surface of the two suspension slides; and two steel beam hoisting ropes, the two first lifting lugs being respectively installed at one end of the two steel beam hoisting ropes; The steel beam hanger is also equipped with a suspension rope support assembly, which includes two limiting sleeves and a support rod. The two limiting sleeves are respectively fixedly installed on the front side of the two suspension slides. The two support rods are vertically slidably inserted into the two limiting sleeves. The bottom end of the support rod is fixedly connected to a rope sleeve, which is sleeved on the outside of the steel beam suspension rope. An adjusting tooth is fixedly installed on the support rod. A round shaft is rotatably installed inside the steel beam hanger. Symmetrical toothed rollers are fixedly fitted on the round shaft. The adjusting tooth meshes with the toothed rollers. A driving component for driving the round shaft to rotate is provided inside the steel beam hanger.

[0006] Preferably, the suspension rope adjustment assembly includes a first servo motor, which is fixedly installed on one side of the steel beam hanger. A bidirectional lead screw is rotatably installed inside the steel beam hanger. One end of the bidirectional lead screw is fixedly connected to the output end of the first servo motor. An adjustment slide rail parallel to the bidirectional lead screw is also fixedly installed inside the steel beam hanger. Two suspension slides are slidably installed on the adjustment slide rail, and the two suspension slides are respectively connected to opposite threaded drives on the bidirectional lead screw.

[0007] Preferably, the steel beam hanger is arranged in a bridge-like structure, and there are two adjusting slide rails, which are located on the front and rear sides of the bidirectional lead screw, respectively.

[0008] Preferably, a second lifting lug is fixedly installed on the top of the steel beam hanger, and both the first and second lifting lugs have lifting holes.

[0009] Preferably, the driving component includes a second servo motor, which is fixedly installed inside the steel beam hanger. A worm gear is fixedly connected to the output end of the second servo motor, and a worm wheel is fixedly fitted in the middle of the round shaft. The worm gear meshes with the worm wheel.

[0010] Preferably, the support rod is arranged in an L-shape, and the rope loop is located directly below the first lifting lug.

[0011] Preferably, symmetrical pulleys are rotatably installed inside the rope loop, and the steel beam suspension rope is located between the two pulleys.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a first servo motor to drive a bidirectional lead screw to rotate, which in turn drives two suspension slides to move closer or further apart along an adjustable slide rail. This allows the distance between the top ends of the two steel beam hoisting ropes to be adjusted according to the length of the steel beam, ensuring that the steel beam hoisting ropes and the steel beam are in an optimal hoisting angle range, thus guaranteeing the stability and safety of the steel beam hoisting.

[0013] This invention drives a circular shaft to rotate via a drive component. The toothed roller engages with the adjusting teeth, causing the rope loop at the bottom of the support rod to descend. This restrains the steel beam hoisting rope, preventing it from swaying or shifting excessively during hoisting, and further improving the stability and safety of the hoisting process.

[0016] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0017] As attached Figure 1 To be continued Figure 5 This utility model provides a steel beam hoisting tool, including a steel beam hanger 1; a hoisting rope adjustment assembly 2, on which two symmetrical suspension slides 3 are provided, the hoisting rope adjustment assembly 2 being used to adjust the distance between the two suspension slides 3; two first lifting lugs 4, the two first lifting lugs 4 being fixedly connected to the bottom surface of the two suspension slides 3 respectively; two steel beam hoisting ropes 7, the two first lifting lugs 4 being respectively installed together with one end of the two steel beam hoisting ropes 7; the hoisting rope adjustment assembly 2 includes a first servo motor 201, the first servo motor 201 being fixedly installed on one side of the steel beam hanger 1; a bidirectional lead screw 202 being rotatably installed inside the steel beam hanger 1, one end of the bidirectional lead screw 202 being fixedly connected to the output end of the first servo motor 201; an adjustment slide rail 203 parallel to the bidirectional lead screw 202 being fixedly installed inside the steel beam hanger 1; both suspension slides 3 being slidably installed on the adjustment slide rail 203, and the two suspension slides 3 being respectively connected to opposite threaded drives on the bidirectional lead screw 202.

[0018] In this process, the bottom ends of the two steel beam lifting ropes 7 are respectively fitted onto both ends of the steel beam. The lifting equipment is started, so that the steel beam lifting ropes 7 slightly lift the steel beam. At this time, the first servo motor 201 drives the bidirectional lead screw 202 to rotate, which can drive the two suspension slides 3 to move closer or further apart along the adjusting slide rail 203. This adjusts the distance between the top ends of the two steel beam lifting ropes 7 according to the length of the steel beam, so that the steel beam lifting ropes 7 and the steel beam are in a better lifting angle range, ensuring the stability and safety of the steel beam lifting.

[0019] Preferably, the steel beam hanger 1 is arranged in a bridge-shaped structure, and there are two adjusting slide rails 203, which are located on the front and rear sides of the bidirectional screw 202 respectively.

[0020] Preferably, a second lifting lug 6 is fixedly installed on the top of the steel beam hanger 1. Both the first lifting lug 4 and the second lifting lug 6 are provided with lifting holes. During use, lifting tools can be installed on the lifting equipment through the second lifting lug 6.

[0021] Furthermore, the steel beam hanger 1 is also equipped with a suspension rope support assembly 5, which includes two limiting sleeves 501 and a support rod 502. The two limiting sleeves 501 are respectively fixedly installed on the front side of the two suspension slides 3. The two support rods 502 are vertically slidably inserted into the two limiting sleeves 501. The bottom end of the support rod 502 is fixedly connected to a rope sleeve 503, which is sleeved on the outside of the steel beam suspension rope 7. An adjusting tooth 504 is fixedly installed on the support rod 502. A round shaft 505 is rotatably installed inside the steel beam hanger 1. Symmetrical toothed rollers 506 are fixedly fitted on the round shaft 505. The adjusting tooth 504 meshes with the toothed rollers 506. The steel beam hanger 1 is also equipped with a driving component 507 for driving the round shaft 505 to rotate.

[0022] When the steel beam is slightly lifted, the drive component 507 can drive the round shaft 505 to rotate, and the toothed roller 506 engages with the adjusting tooth 504, causing the rope loop 503 at the bottom of the support rod 502 to descend, which plays a restraining role on the steel beam lifting rope 7, preventing the steel beam lifting rope 7 from excessive shaking or deviation during the lifting process, further improving the stability and safety of the lifting, and can be combined with the lifting rope adjustment component 2 for diversified adjustments.

[0023] Preferably, the drive component 507 includes a second servo motor 5071, which is fixedly installed inside the steel beam hanger 1. A worm gear 5072 is fixedly connected to the output end of the second servo motor 5071, and a worm wheel 5073 is fixedly fitted in the middle of the round shaft 505. The worm gear 5072 and the worm wheel 5073 mesh with each other.

[0024] The second servo motor 5071 drives the worm gear 5072 to rotate, which in turn meshes with the worm wheel 5073 to drive the round shaft 505 to rotate. At the same time, the action of the worm gear 5072 and the worm wheel 5073 can lock the round shaft 505.

[0025] Preferably, the support rod 502 is arranged in an L-shape, and the rope loop 503 is located directly below the first lifting lug 4.

[0026] Preferably, symmetrical pulleys 508 are rotatably installed inside the rope loop 503, and the steel beam suspension rope 7 is located in the middle of the two pulleys 508. The arrangement of the pulleys 508 reduces the wear between the rope loop 503 and the steel beam suspension rope 7.

[0027] The first servo motor 201 and the second servo motor 5071 mentioned above can be started and stopped using existing switch control technology or remote control technology, which will not be elaborated on here.
