Description

Technical Field

[0001] This utility model relates to the hoisting of I-beams, specifically to a simple auxiliary device for hoisting I-beams. Background Technology

[0002] I-beams are high-efficiency steel sections with an "I" shape. They consist of two relatively wide flanges at the top and bottom and a web that is vertically connected in the middle. This unique structure allows the material to be preferentially distributed on the flanges away from the neutral axis when subjected to vertical loads, thus giving it extremely high bending strength and stability.

[0003] Currently, during the hoisting of I-beams, steel wire ropes are commonly used to bind and hoist them. However, due to the special cross-section of the I-beam, this method results in less contact between the steel wire rope and the I-beam, leading to insufficient friction and a risk of the I-beam falling off during hoisting, which poses a safety hazard. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model proposes a simple auxiliary device for hoisting I-beams, including a fixing plate. The lower part of the side wall of the fixing plate is provided with an inclined groove, and the upper part of the fixing plate has a through hole. The fixing plate is provided with four holes. It also includes an I-beam, with four fixing plates located at the four corners of the I-beam, and the fixing plates are inserted into the upper flange of the I-beam through the grooves; The four fixing plates are arranged in pairs, with the center lines of the through holes of each pair of fixing plates coinciding. Each pair of fixing plates is equipped with a crossbar that passes through the through hole, and the crossbar is fixedly connected to the fixing plate. The crossbar is nested with a limiting plate that is rotatably connected to the crossbar. The bottom end of the limiting plate abuts against the upper surface of the I-beam. The top end of the limiting plate is rotatably connected to an arched shackle, which is connected to a lifting rope.

[0005] To achieve the above objectives, four fixing plates clamp the four corners of the upper flange of the I-beam, forming a stable clamping structure. This reduces the swaying and twisting of the I-beam during hoisting, ensuring smooth hoisting and improving the safety of the hoisting. During hoisting, under the action of gravity and the suspended weight, the bottom of the limiting plate is tightly attached to the upper surface of the I-beam, forming a self-locking structure. Together with the fixing plates, this further improves the clamping force and stability of the device on the I-beam.

[0006] Furthermore, a limiting component is provided outside the limiting plate to limit the rotation angle of the limiting plate.

[0007] Furthermore, the limiting component includes a limiting strip disposed outside the limiting plate. The limiting strip is U-shaped, and both ends of the limiting strip extend to the crossbar and are tied and fixed to the crossbar.

[0008] Furthermore, an anti-slip pad is fixed to the inner surface of the groove, and an anti-slip sleeve is fixed to the outside of the limiting plate.

[0009] Furthermore, the fixing plate is made of steel plate, and the thickness of the steel plate is 25-30mm.

[0010] Furthermore, a wear-resistant bushing is fixed to the inner wall of the through hole, and a fixing plate extends from both ends of the wear-resistant bushing. The part of the wear-resistant bushing extending from the fixing plate is connected to the fixing plate by a reinforcing rib. The crossbar passes through the two wear-resistant bushings, and the crossbar, the wear-resistant bushings, and the fixing plate are fixedly connected.

[0011] In summary, this simple auxiliary device for hoisting I-beams has the following beneficial effects: the four fixing plates clamp the four corners of the upper flange of the I-beam, forming a stable clamping structure, reducing the swaying and twisting of the I-beam during hoisting, achieving smooth hoisting of the I-beam, and improving the safety of hoisting. During hoisting, under the action of gravity and the suspended weight, the bottom end of the limiting plate is tightly attached to the upper surface of the I-beam, forming a self-locking structure. Together with the fixing plates, this further improves the clamping force and clamping stability of the device on the I-beam. Attached Figure Description

[0015] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0016] like Figure 1-3As shown, the preferred embodiment of this utility model provides a simple auxiliary device for hoisting I-beams, including a fixing plate 1. The lower part of the side wall of the fixing plate 1 has an inclined groove 2, and the upper part of the fixing plate 1 has a through hole 3. Four fixing plates 1 are provided. It also includes an I-beam 4, with the four fixing plates 1 located at the four corners of the I-beam 4. The fixing plates 1 are inserted into the upper flange of the I-beam 4 through the groove 2. The four fixing plates 1 are arranged in pairs, with the center lines of the through holes 3 of each pair coinciding. Each pair of fixing plates 1 is equipped with a horizontal bar 5 penetrating the through hole 3, and the horizontal bar 5 is fixedly connected to the fixing plate 1. A limiting plate 6, rotatably connected to the horizontal bar 5, is nested outside the horizontal bar 5. The bottom end of the limiting plate 6 abuts against the upper surface of the I-beam 4, and the top end of the limiting plate 6 is rotatably connected to an arched shackle 7. The arched shackle 7 is connected to a hoisting rope, which is connected to a crane.

[0017] Four fixing plates 1 clamp the four corners of the upper flange of the I-beam 4, forming a stable clamping structure. This reduces the swaying and twisting of the I-beam 4 during hoisting, ensuring smooth hoisting and improving the safety of the hoisting. During hoisting, the bottom of the limiting plate 6 is pressed tightly against the upper surface of the I-beam 4 under the action of gravity and the hoisting weight, forming a self-locking structure. Together with the fixing plates 1, this further improves the clamping force and stability of the device on the I-beam 4. The device has a simple structure, low cost, and is convenient for workers to use on the construction site.

[0018] A limiting component is provided outside the limiting plate 6 to limit the rotation angle of the limiting plate 6.

[0019] like Figure 2 and Figure 3 As shown, the limiting component includes a limiting strip 8 disposed outside the limiting plate 6. The limiting strip 8 is U-shaped, and both ends of the limiting strip 8 extend to the crossbar 5 and are tied and fixed to the crossbar 5. The two ends of the U-shaped limiting strip 8 are detachably fixed to the crossbar 5. The limiting strip 8 is located beside the limiting plate 6 and limits the rotation angle of the limiting plate 6, further improving the safety and stability of the device.

[0020] like Figure 2 and Figure 3 As shown, an anti-slip pad is fixed to the inner surface of the groove 2, and an anti-slip sleeve is fixed to the outside of the limiting plate 6. By setting an anti-slip pad inside the groove 2 and an anti-slip sleeve outside the limiting plate 6, the stability of the connection between the fixing plate 1 and the limiting plate 6 and the I-beam 4 is improved, while the possibility of the fixing plate 1 and the limiting plate 6 scratching the I-beam 4 is also reduced.

[0021] like Figure 2 and Figure 3 As shown, the fixing plate 1 is made of steel plate, and the thickness of the steel plate is 25-30mm.

[0022] Wear-resistant bushings are fixed to the inner wall of the through hole 3. Fixing plates 1 extend from both ends of the wear-resistant bushings, and the portions of the wear-resistant bushings extending from the fixing plates 1 are connected to the fixing plates 1 via reinforcing ribs. A crossbar 5 passes through both wear-resistant bushings, and the crossbar 5, wear-resistant bushings, and fixing plates 1 are fixedly connected. By setting wear-resistant bushings to bear the friction and compression of the crossbar 5, the contact area between the crossbar 5 and the wear-resistant bushings is increased, reducing the possibility of wear deformation and breakage of the through hole 3 during hoisting. The wear-resistant bushings are made of high-hardness, high-strength bearing steel.

[0023] In use, the staff will place four fixing plates 1 at the four corners of the upper flange of the I-beam 4, and make the fixing plates 1 nested in the grooves 2 outside the upper flange of the I-beam 4. Then the crossbar 5 passes through two adjacent through holes 3 and wear-resistant bushings, and the crossbar 5, wear-resistant bushings and fixing plates 1 are fixedly connected. The limiting plate 6 is rotatably nested outside the crossbar 5 and located between two adjacent fixed plates 1. The arched shackle 7 is rotatably connected to the limiting plate 6. The arched shackle 7 is connected to the lifting rope, which is connected to the crane. During hoisting, under the action of gravity and the load, the bottom end of the limiting plate 6 is tightly attached to the upper surface of the I-beam 4, and the fixed plate 1 is clamped to the I-beam 4 to facilitate stable hoisting.

Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention.
