Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel structure hoisting device used indoors. Background Art

[0002] During the construction process, since scattered steel structures cannot be constructed synchronously with the main structure, construction often starts after the main structure is closed, which makes it impossible to use large machinery for lifting, affecting the construction of the steel structure. Therefore, a small and movable steel structure lifting device is needed to lift some scattered steel structures indoors.

[0003] Existing steel structure lifting devices generally use wire ropes and hooks to lift objects. Specifically, the wire ropes are looped around the center or both ends of the steel structure and then connected to the hooks. When lifting some longer steel parts, the two ends are generally looped to ensure balance. However, the existing lifting devices lack an effective limiting structure. During lifting, the bottom end of the wire rope will gradually move toward the center under the pull of the hook, so that most of the two ends of the steel structure have no wire rope loops, resulting in an unbalanced center of gravity, causing the steel structure to slip, seriously threatening the personal safety of ground personnel. Utility Model Content

[0004] In response to the technical problems in the prior art, the utility model provides a steel structure lifting device for indoor use, comprising an H-shaped steel beam, two columns, a rail-mounted electric hoist and a connecting assembly, wherein the two ends of the H-shaped steel beam are respectively fixedly connected to the two columns, and the end of the column away from the H-shaped steel beam is provided with a driving assembly, the rail-mounted electric hoist is slidably installed on the H-shaped steel beam and is located between the two columns, and the hook of the rail-mounted electric hoist is detachably connected to the steel structure through the connecting assembly, and the connecting assembly comprises two wire rope rings, a sleeve, a sleeve rod and two clips, one end of the sleeve is slidably connected to one end of the sleeve rod and is locked by a bolt, and the other end is fixedly connected to the two wire rope rings through two clips, and the ends of the two wire rope rings away from the sleeve and the sleeve rod are both sleeved on the hook.

[0005] Furthermore, the sleeve rod is provided with size scale lines, and the size scale lines are arranged along the axial direction of the sleeve rod.

[0006] Furthermore, the zero mark of the size scale line is located at the end connected to the buckle.

[0007] Furthermore, multiple telescopic rods are provided between the two wire rope rings, and the multiple telescopic rods are symmetrically arranged on both sides of the sleeve and the sleeve rod. The two ends of the telescopic rods are overlapped with the two wire rope rings, and are fixedly connected to the sleeve and the sleeve rod at one end away from each other through a connecting rod.

[0008] Furthermore, a steel structure lifting device for indoor use also includes a locking assembly, which is installed in two steel wire rope rings and fixedly connected to the two steel wire rope rings through a buckle. The locking assembly is located above the sleeve and the sleeve rod, and a clamping space for clamping the steel structure is enclosed between the locking assembly and the sleeve and the sleeve rod.

[0009] Furthermore, the locking assembly includes a fixed plate, an elastic mechanism and a pressure plate. The top of the fixed plate is fixedly connected to the two steel wire rope rings through a buckle, and the pressure plate is connected to the bottom of the fixed plate through the elastic mechanism. The end of the pressure plate away from the elastic mechanism abuts against the steel structure under the action of the elastic mechanism.

Combined with the arrangement of the sliding connection between the sleeve and the sleeve rod, the distance between the bottom ends of the two wire rope rings can be adjusted to meet the lifting requirements of steel structures of different lengths.

[0012] 2. In the present invention, the distance between the bottom ends of the two wire rope thimbles can be accurately adjusted by setting the size scale line, thereby improving the connection efficiency between the wire rope thimbles and the steel structure, and further ensuring the balance of the center of gravity of the steel structure and improving safety performance; combined with the setting that the zero scale of the size scale line is located at the end connected to the buckle, it is convenient to read the number, and specifically the distance between the bottom ends of the two wire rope thimbles is equal to the sum of the length of the sleeve and the reading of the size scale line.

[0013] 3. In the present invention, by providing multiple telescopic rods, the supporting area of ​​the steel structure can be further increased, thereby improving safety performance.
