[0030] Please refer to Figure 1 This utility model provides a hoisting corner protection device 100, including a corner protection mechanism 10. The corner protection mechanism 10 includes a first load-bearing corner block 12 and a first anti-slip buffer pad 14. A first recessed bending portion 122 is provided on one side of the first load-bearing corner block 12, and the first anti-slip buffer pad 14 is attached to the first recessed bending portion 122. A limiting groove 124 is provided on the opposite side of the first load-bearing corner block 12.
[0031] When hoisting the precast T-beam, the first anti-slip buffer pad 14 is placed over the corner of the precast T-beam, and the wire rope is secured in the limiting groove 124. Then, a crane is used to hoist the precast T-beam. It is understood that the hoisting corner protector 100 of this embodiment can also be applied to other heavy hoisting workpieces. In the hoisting corner protector 100 of this embodiment, the first anti-slip buffer pad 14 is in direct contact with the corner of the precast T-beam. The first anti-slip buffer pad 14 has anti-slip and buffering functions. The first load-bearing corner block 12 can bear the weight. The first concave bending portion 122 of the first load-bearing corner block 12 is used to accommodate the first anti-slip buffer pad 14. The first load-bearing corner block 12 contacts the precast T-beam through the first anti-slip buffer pad 14, increasing the contact area with the precast T-beam and thus reducing the phenomenon of force concentration. The limiting groove 124 serves to limit the movement of the wire rope. Simultaneously, when the wire rope is engaged within the limiting groove 124, the contact area for stress distribution increases, further reducing stress concentration. This prevents damage to the precast T-beam and avoids affecting the quality and appearance of the hoisted workpiece.
[0032] Please refer to Figure 2 and Figure 3 In one embodiment, the first load-bearing corner block 12 includes a first load-bearing plate 126 and a second load-bearing plate 128. The first load-bearing plate 126 and the second load-bearing plate 128 are connected to form a first preset angle to form a first recessed bending portion 122. The first load-bearing plate 126 is provided with a first groove 1242 on the side away from the first recessed bending portion 122, and the first groove 1242 extends along the length direction of the first load-bearing plate 126. The second load-bearing plate 128 is provided with a second groove 1244 on the side away from the first recessed bending portion 122, and the second groove 1244 extends along the length direction of the second load-bearing plate 128. The second groove 1244 and the first groove 1242 are connected at the connection between the first load-bearing plate 126 and the second load-bearing plate 128 to form a limiting groove 124. The first preset included angle is 90°. It can be understood that, depending on the situation of hoisting the workpiece, the first preset included angle can also be other angles, such as 85°, 120°, etc. That is, the first recessed bending part 122 is located on the inner side of the first load-bearing corner block 12, and the limiting groove 124 is located on the outer side of the first load-bearing corner block 12. With this arrangement, the wire rope is better stressed, the covering effect of the precast T-beam is better, and the stress area of the precast T-beam is further increased.
[0033] In one embodiment, the lifting corner protection device 100 includes a connecting mechanism 20 and at least two corner protection mechanisms 10. The connecting mechanism 20 includes a second load-bearing corner block 22 and a second anti-slip buffer pad 24. One side of the second load-bearing corner block 22 is provided with a second recessed bending portion, and the second anti-slip buffer pad 24 is attached to the second recessed bending portion. A second load-bearing corner block 22 is connected between any two adjacent first load-bearing corner blocks 12, and a second anti-slip buffer pad 24 is connected between any two adjacent first anti-slip buffer pads 14. The second anti-slip buffer pad 24 is in direct contact with the corner of the precast T-beam. The second anti-slip buffer pad 24 has the functions of anti-slip and buffering. The second load-bearing corner block 22 can bear the weight. The second recessed bending portion of the second load-bearing corner block 22 is used to accommodate the second anti-slip buffer pad 24. The second load-bearing corner block 22 contacts the precast T-beam through the second anti-slip buffer pad 24, further increasing the contact area with the precast T-beam, thereby reducing the phenomenon of force concentration. In one embodiment, the number of corner protection mechanisms 10 is three and the number of connecting mechanisms 20 is two. This arrangement further increases the stress-bearing area of the precast T-beam and reduces the phenomenon of stress concentration.
[0034] In one embodiment, the second load-bearing corner block 22 includes a third load-bearing plate 226 and a fourth load-bearing plate 228. The third load-bearing plate 226 and the fourth load-bearing plate 228 are connected to form a second preset angle to form a second recessed bending portion. A third load-bearing plate 226 is connected between any two adjacent first load-bearing plates 126, and a fourth load-bearing plate 228 is connected between any two adjacent second load-bearing plates 128. The first preset angle and the second preset angle are equal. The second preset angle is 90°. It is understood that, depending on the lifting situation of the workpiece, the second preset angle can also be other angles, such as 85°, 120°, etc. That is, the second recessed bending portion is located inside the second load-bearing corner block 22. This arrangement provides better coverage for the precast T-beam and further increases the load-bearing area of the precast T-beam.
[0035] In one embodiment, the first load-bearing plate 126, the second load-bearing plate 128, the third load-bearing plate 226, and the fourth load-bearing plate 228 are integrally formed, as are the first anti-slip buffer pad 14 and the second anti-slip buffer pad 24. This arrangement improves the strength of the first load-bearing corner block 12 and the second load-bearing corner block 22, as well as the strength of the first anti-slip buffer pad 14 and the second anti-slip buffer pad 24, thereby enhancing the safety of hoisting operations.
[0036] In one embodiment, the first load-bearing plate 126, the second load-bearing plate 128, the third load-bearing plate 226, and the fourth load-bearing plate 228 are angle steel blocks, and the first anti-slip buffer pad 14 and the second anti-slip buffer pad 24 are rubber pads. This arrangement can further improve the strength of the first load-bearing corner block 12 and the second load-bearing corner block 22, and give the first anti-slip buffer pad 14 and the second anti-slip buffer pad 24 a better anti-slip buffering effect.
[0037] In one embodiment, the corner of the limiting groove 124 is provided with a chamfered arc surface. By setting it in this way, the contact area and fit between the limiting groove 124 and the wire rope can be further improved, thereby further reducing the phenomenon of force concentration.
[0038] Please refer to Figures 4 to 6 In one embodiment, the lifting corner protector 100 further includes a locking mechanism 30, which is disposed on the first load-bearing corner block 12 and located at the limiting groove 124 to lock and limit the wire rope. By setting the locking mechanism 30, the wire rope is prevented from coming out of the limiting groove 124 during lifting operations, ensuring the safety of the lifting operation. It is understood that, according to user needs, the locking mechanism 30 can be set on the first load-bearing plate 126 and / or the second load-bearing plate 128 to ensure the safety of the lifting operation.
[0039] In one embodiment, the locking mechanism 30 includes a hook 32 and a locking post 34. The hook 32 includes a hinge end 322 and a hook end 324. The hinge end 322 is hinged to the first load-bearing corner block 12, and the locking post 34 is disposed on the first load-bearing corner block 12. The hinge end 322 and the locking post 34 are respectively located on opposite sides of the limiting groove 124, and the hook end 324 and the locking post 34 are detachably connected. The hinge end 322 is connected to the first load-bearing plate 126 and / or the second load-bearing plate 128 through a pin or other structure, so that the hook end 324 can rotate relative to the hinge end 322. When the wire rope is placed in the limiting groove 124, the hook end 324 and the locking post 34 are engaged, thus preventing the wire rope from coming out of the limiting groove 124.
[0040] In one embodiment, the locking mechanism 30 further includes a ball head 36, and the locking post 34 is cylindrical. The ball head 36 is located on the hook end 324, and the ball head 36 and the cylinder cooperate to limit the hook end 324. When the hook end 324 and the cylinder are detachably connected, since the surfaces of the ball head 36 and the cylinder are curved, the ball head 36 can pass through the cylinder in a pressing manner, so that the hook end 324 is on the cylinder. Furthermore, the cooperation between the ball head 36 and the cylinder can limit the hook end 324, preventing the hook end 324 from falling off the cylinder, thereby ensuring that the wire rope is released from the limiting groove 124 and ensuring the safety of the hoisting operation.
[0041] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
