Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to prefabricated building hoisting steel beams. Background Technology

[0002] The steel beam hoisting equipment for prefabricated buildings is a core auxiliary equipment for prefabricated building construction. Its core function is to provide temporary fixing and hoisting connection points for the steel beams, ensuring that the steel beams remain stable during hoisting, positioning, and splicing, and preventing displacement or falling.

[0003] Traditional hoisting equipment is mostly of fixed size and can only be adapted to a single specification of steel beam, resulting in poor versatility; the connection structure is rudimentary and lacks anti-detachment protection, making it easy for the connecting bolts to loosen and fall off during hoisting; the adjustment structure is poorly designed and cannot quickly adapt to the width and height of the steel beam, thus prolonging the construction time. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a prefabricated building hoisting steel beam, including a fixed plate 1 and a steel beam 8. Four sets of sliding grooves 2 are symmetrically opened on both sides of the upper and lower fixed plates 1. A transverse sliding plate 3 is slidably connected inside the sliding groove 2 through a clearance fit, which can move laterally along the sliding groove 2. A connecting block 4 is fixedly connected to one end of the two sets of transverse sliding plates 3 on the same side by welding. A longitudinal sliding plate 5 is fixedly connected to the lower part of both sides of the upper and lower connecting blocks 4 by welding. A connecting plate 6 is slidably connected to the outer side of the longitudinal sliding plate 5 through a clearance fit. A first connecting hole 7 is opened inside the connecting plate 6 for docking with the installation hole of the steel beam 8 itself. The steel beam 8 is sleeved between the upper and lower fixed plates 1 and the left and right sets of connecting plates 6 to form an enclosed positioning. Hooks 9 are fixedly connected to the upper two sides of the upper fixed plate 1 by welding for connecting hoisting equipment to realize the hoisting of the steel beam 8. Two sets of lifting rods 10 are slidably connected inside the upper fixed plate 1 through clearance fit. The lower part of the lifting rod 10 is fixedly connected to the pressure plate 11 by welding. The upper part of the lifting rod 10 is fixedly connected to the lifting plate 12 by welding. The lifting plate 12 is connected to the first threaded rod 13 by thread. The first threaded rod 13 is rotatably connected to the upper part of the upper fixed plate 1 through a deep groove ball bearing. When rotating, it drives the lifting plate 12 to move up and down, thereby driving the pressure plate 11 to press or release the steel beam 8. The upper part of the upper fixing plate 1 is fixedly connected to the upper connecting box 14 by welding. The upper connecting box 14 is sleeved on the outside of the lifting plate 12 to protect and position the lifting structure and prevent displacement. The first threaded rod 13 is rotatably connected to the upper inside of the upper connecting box 14 by a deep groove ball bearing to ensure smooth rotation. A rubber pad 15 is bonded to the lower part of the pressure plate 11 and the upper part of the lower fixing plate 1. The rubber pad 15 dampens the vibration during the hoisting process, prevents the pressure plate 11 and the fixing plate 1 from directly squeezing and damaging the surface of the steel beam 8, and increases the friction force to improve the fixing stability. The lower part of the lower fixed plate 1 is fixedly connected to the lower connecting box 20 by welding. The lower connecting box 20 and the lower fixed plate 1 are connected by a communicating groove 16 that communicates with the sliding groove 2. The lower part of the four sets of transverse sliding plates 3 are fixedly connected to the lower part by welding with lugs 17. The lugs 17 are slidably connected to the inside of the communicating groove 16 by clearance fit. The two sets of lugs 17 on the front side are slidably connected to the inside of the lower connecting box 20 by clearance fit. The two ends of the guide rods 18 are fixedly connected to the inside of the lower connecting box 20 by welding to provide width adjustment guidance. The two sets of lugs 17 on the rear side are connected to the inside of the second threaded rods 19 by threads. The second threaded rods 19 are rotatably connected to the inside of the lower connecting box 20 by deep groove ball bearings. When rotated, they drive the transverse sliding plates 3 to move closer or further away synchronously to adjust the width. Connecting plate 6 is fixedly connected to connecting frame 21 by welding on both sides. Inside connecting frame 21, baffle 22 is slidably connected by clearance fit. One end of baffle 22 and one side of connecting frame 21 have mutually cooperating second connecting holes 23. Bolts are passed through the second connecting holes 23 to fix the position of baffle 22, cover the connecting screw in the first connecting hole 7, and prevent it from falling off. The end of the baffle 22 away from the second connecting hole 23 is fixedly connected to the limiting plate 24 by welding. The limiting plate 24 prevents the baffle 22 from sliding excessively and detaching from the connecting frame 21, thus ensuring the reliability of the protection.

[0017] Working Principle: In use, this utility model, based on the width of the steel beam 8 to be hoisted, rotates the second threaded rod 19, which, through the deep groove ball bearing, drives the rear lug 17 to slide the transverse sliding plate 3 along the sliding groove 2 and guide rod 18, adjusting the distance between the left and right sets of connecting plates 6 to match the width of the steel beam 8. The connecting plate 6 is moved up and down along the longitudinal sliding plate 5, aligning the first connecting hole 7 of the connecting plate 6 with the pre-set connecting hole of the steel beam 8, thus achieving height matching. The frame composed of the upper and lower sets of fixing plates 1 and connecting plates 6 is fitted onto the outside of the steel beam 8, ensuring precise alignment of the first connecting hole 7 with the mounting hole of the steel beam 8. A connecting screw is inserted, passing through the first connecting hole 7 and the mounting hole of the steel beam 8, initially fixing the equipment to the steel beam 8. Rotating the first threaded rod 13 drives the lifting plate 12 and lifting rod 10 downwards, causing the rubber pad 15 at the bottom of the pressure plate 11 to press tightly against the upper surface of the steel beam 8. The first threaded rod 13 is continuously tightened until the pressure plate 11 presses firmly against the steel beam 8, eliminating the gap between the equipment and the steel beam 8, thus achieving stable fixing.

[0018] The sliding baffle 22 moves along the connecting frame 21 until the baffle 22 completely covers the exposed part of the connecting screw; the inserted bolt passes through the second connecting hole 23 between the baffle 22 and the connecting frame 21, and is tightened to fix the position of the baffle 22; the limiting plate 24 fits against the outside of the connecting frame 21 to prevent the baffle 22 from shifting. Connect the hook of the hoisting equipment to the hook 9 of the upper fixed plate 1, and check all connection points and fixed structures to ensure that there is no looseness.
