Description

Technical Field

[0001] The utility model belongs to the technical field of I-shaped steel hoisting, and particularly relates to an I-shaped steel hoisting device. Background Technique

[0002] I-shaped steel, also known as H-shaped steel, is an economic section high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the Chinese character "工". Since all parts of the I-shaped steel are arranged at right angles, the I-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving, and light structural weight, and has been widely used. When large I-shaped steels are applied, hoisting equipment is usually used to hoist and move them because of their heavy weight.

[0003] The patent document with the publication number of CN206156566U discloses an H-shaped steel column hoisting tool, including a hoisting belt. The hoisting belt is a synthetic fiber hoisting belt, and chucks are provided at both ends of the hoisting belt. The chucks are made of metal materials. The chuck includes a round rod, and chuck plates are provided at both ends of the round rod. Slots are provided on the chuck plates, and the slots are used to partially hold the steel section to be hoisted, so as to achieve the hoisting effect.

[0004] When the above-mentioned comparative document is used, since it only relies on the connection between the chuck and the I-shaped steel, it can be used for hoisting slightly shorter I-shaped steels. However, for I-shaped steels with larger weights or lengths, the chuck fixation is not secure enough and is prone to falling off due to strong winds or vibrations. Moreover, the above-mentioned comparative document relies on the hoisting belt for hoisting, and its structural strength is not sufficient to hoist I-shaped steels with larger weights.

[0010] Furthermore, in order to make the slide on the slide rod have a locking capability, the slide is provided with a threaded through hole, in which a fastening bolt is threadedly engaged, and the slide and the slide rod can be clamped by rotating the fastening bolt.

[0013] Furthermore, in order to make the grab bar detachable, the top end of the vertical portion of the grab bar is configured as a threaded rod, and the threaded rod penetrates the suspension beam and is fixed with a detachable nut.

[0014] Furthermore, in order to make the pressure plate have buffering and anti-slip capabilities, the main body of the pressure plate is a shell structure with an inverted U-shaped longitudinal section.
