Technical Field

[0001] The utility model relates to the technical field of H-beam hoisting, in particular to an H-beam hoisting device. Background Art

[0002] H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, it has the advantages of strong bending resistance in all directions, simple construction, cost savings and light structural weight, and has been widely used.

[0003] At present, H-beams are mostly hoisted by wire rope tying, cutting holes, welding lifting noses or slot hoisting methods, all of which have certain disadvantages: wire rope tying: it is not easy to tie the stacked I-beams, which is inefficient and it is not easy to find the angle of the steel during installation; cutting holes or welding lifting noses: certain changes need to be made to the steel, which is inefficient or affects secondary use; slot hoisting method, the clamps need to be installed at both ends, and the length of the hoisted I-beam is limited by the length of the wire rope.

[0004] To this end, this solution proposes an H-beam lifting device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3, an H-shaped steel hoisting device, comprising two shackle assemblies respectively arranged at both ends of a steel wire rope 1, both shackle assemblies are provided with a hoisting assembly, the hoisting assembly comprises a vertical plate 2, the vertical plate 2 is provided with a hoisting hole 3, the shackle assembly comprises a U-shaped frame 11 arranged at one end of the steel wire rope 1, a connecting bolt 12 is penetrated through the U-shaped frame 11, one end of the connecting bolt 12 is threadedly connected with a connecting nut 13, and the connecting bolt 12 penetrates the hoisting hole 3, so that the connection work can be completed conveniently, and at the same time, the shackle assembly can be rotated relative to the hoisting assembly, and the steel wire ropes 1 of different lengths are matched to perform hoisting work at different positions of the H-shaped steel, which greatly satisfies the hoisting of the staff. According to the requirements, the vertical plate 2 is also provided with a pin hole 4, in which a pin shaft 5 is slidably connected, one end of the pin shaft 5 is provided with a threaded portion 6, and an end nut 7 is threadedly connected to the threaded portion 6. The pin shaft 5 is rotatably connected in the pin hole 4, and both ends of the pin shaft 5 are provided with hanging plates 8. A slot 16 is provided on the side wall of the two hanging plates 8 close to each other. The two slots 16 are slidably connected with a plug column 17. Different plug columns 17 can cooperate with the two hanging plates 8 to complete the hoisting of H-shaped steels of different specifications. With the help of the plug column 17, the two hanging plates 8 can be kept synchronized more stably, and relative rotation will not occur, which will cause the threaded portion 6 and the end nut 7 to rotate and fall off.

[0021] The two hanging plates 8 are each provided with a connecting hole 9, and the pin shaft 5 and the threaded portion 6 are respectively rotatably connected in the two connecting holes 9. A hanging plate 10 is provided on the side wall where the two hanging plates 8 are close to each other. In this way, with the help of the bending cooperation between the hanging plate 8 and the hanging plate 10, the hanging work can be smoothly completed from the bending part of the H-shaped steel. The hanging plate 8 and the hanging plate 10 are connected by welding. Such a connection is more firm and stable, and the hanging work can be better completed. A baffle plate 14 is fixedly connected to the side wall of the vertical plate 2 close to the two hanging plates 10. The baffle plate 14 can resist the clamped H-shaped steel, making the lifting work more stable. Two reinforcing plates 15 are fixedly connected to the upper end surface of the baffle plate 14, and the two reinforcing plates 15 are respectively fixedly connected to the side walls at both ends of the vertical plate 2, so that the baffle plate 14 is more firm, and then the auxiliary work is better completed.

[0022] During the use of the utility model, firstly, the two ends of the steel wire rope 1 are connected to the two U-shaped frames 11 respectively, and then the hanging plates 10 on the two hanging plates 8 are inserted into the bending parts of the H-shaped steel from both sides. When assembling the two hanging plates 8, the two ends of the plug column 17 are respectively inserted into the two slots 16, so that the two hanging plates 8 and the two hanging plates 10 will not be misaligned and rotated by means of the restriction of the slots 16 on the plug column 17. Then, the vertical plate 2 can be placed between the two hanging plates 8, and then the pin shaft 5 and the threaded portion 6 are passed through the pin hole 4 and the connecting hole 9, and then the end nut 7 is threadedly connected to the threaded portion 6 to complete the connection work, so that the connection between the two hanging plates 8 is successfully completed. The connection work allows the two lifting plates 10 to smoothly complete the clamping work of the H-shaped steel, and then the U-shaped frame 11 can be aligned with the lifting hole 3, and then the connecting bolt 12 is passed through the U-shaped frame 11 and the lifting hole 3, and the connecting nut 13 is threadedly connected to the connecting bolt 12 to complete the connection work, and then the H-shaped steel can be lifted with the help of the wire rope 1. Such lifting force transmission is not concentric, which effectively prevents the connection point from slipping toward the center, so that the two lifting components can smoothly complete the stable lifting work of the H-shaped steel without sliding, so that the device can smoothly complete the lifting work of H-shaped steel of different lengths, and can complete the lifting work of H-shaped steel of different specifications through adjustment, which greatly meets the use needs of the staff.
