Description

Technical Field

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

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of constructing various buildings. It can also be described as the process of transforming the various lines on the design drawings into physical objects at designated locations. It includes foundation construction, main structure construction, roofing construction, and decorative engineering. The location where construction takes place is called a "construction site," also known as a "worksite."

[0003] At a construction site, steel pipes often need to be transported to the construction floor by a crane. However, when fixing them, the steel pipes are generally tied to the hooks using ropes. Since the surface of the steel pipes is relatively smooth, the fixation with a single rope is not very firm, and there is a risk of the steel pipes falling from a height. Based on the deficiencies of the existing technology, the utility model designs a steel structure lifting clamp. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a steel structure hoisting clamp, which has the advantage of preventing steel pipes from falling from high altitudes.

[0005] The utility model provides the following technical solutions: a steel structure lifting fixture, comprising a first support rod and a second support rod, wherein a clamping structure is installed on the top of the first support rod and the second support rod; the two clamping structures include support plates, threaded rods are rotatably installed inside the two support plates, a turning handle is fixedly installed at one end of the two threaded rods, and a vertical plate is rotatably installed at the other end of the two threaded rods, a limiting rod is fixedly installed on one side of the two vertical plates, the two limiting rods are movably connected to the support plates, an adapter plate is installed on the bottom of the two vertical plates, and an arc panel is fixedly installed on one side of the two adapter plates by bolts.

[0006] As a preferred technical solution of the present invention, the first support rod is slidably connected to the second support rod, four support rods are fixedly installed on one side of the second support rod, and the four support rods are movably connected to the first support rod.

[0007] As a preferred technical solution of the present invention, side grooves are provided on both sides of the outer surface of the first support rod, and a hook is installed on the top of the first support rod.

[0008] As a preferred technical solution of the present invention, fixing structures are installed on both sides of the outer surface of the second support rod, and the two fixing structures include a connecting long rod.

[0009] As a preferred technical solution of the present invention, the two connecting long rods are slidably connected to the second support rod, and a plurality of positioning holes are opened inside the two connecting long rods.

[0010] As a preferred technical solution of the present invention, locking bolts are threadedly installed in the two positioning holes.

[0011] As a preferred technical solution of the present invention, the two locking bolts are threadedly connected to the first support rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This steel structure lifting fixture uses a clamping structure to place the steel pipe under the first support rod when lifting and clamping the steel pipe. The steel pipe is clamped and fixed by adjusting the clamping structures on the left and right sides. The threaded rod is driven to rotate by turning the handles on both sides. Due to the limitation of the two limiting rods on the side, the threaded rod drives the vertical plate to move horizontally, thereby allowing the lower arc plate to extend into both sides of the steel pipe. The arc surfaces of the two arc plates are tightly attached to the upper inner wall of the steel pipe, thereby achieving clamping and fixing from both sides, thereby achieving the purpose of avoiding the risk of high-altitude falling in the traditional rope fixing method of steel pipe.

[0014] 2. This kind of steel structure lifting clamp uses a first support rod, a second support rod, and a fixed structure. When lifting and clamping a steel pipe, the fixed structure is adjusted according to the length of the steel pipe. The locking bolts on both sides are loosened and pulled out, and then the second support rod is pulled out from the first support rod to a certain length. After confirming that it meets the length of the steel pipe, the locking bolt is inserted into the corresponding positioning hole and fixed again. In this way, the length of the device can be flexibly adjusted to adapt to steel pipes of different lengths. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 1-2 The first support rod 1 is slidably connected to the second support rod 2. Four support rods 7 are fixedly installed on one side of the second support rod 2. The four support rods 7 are movably connected to the first support rod 1. Side grooves 4 are opened on both sides of the outer surface of the first support rod 1, and a hook 5 is installed on the top of the first support rod 1.

[0023] By the arrangement of four support rods 7, the second support rod 2 can be supported when it extends from the inside of the first support rod 1. The device can be connected to the crane by a hook 5.

[0024] See also Figure 1-3 The second support rod 2 is provided with fixing structures 6 mounted on both sides of its outer surface. The fixing structures 6 include connecting rods 61. The connecting rods 61 are slidably connected to the second support rod 2 and have multiple positioning holes 62 defined therein. Locking bolts 63 are threadedly mounted in the positioning holes 62. The locking bolts 63 are threadedly connected to the first support rod 1.

[0025] When hoisting and clamping the steel pipe, the fixing structure 6 is adjusted according to the length of the steel pipe. The locking bolts 63 on both sides are loosened and pulled out, and then the second support rod 2 is pulled out from the first support rod 1 to a certain length. After confirming that it meets the length of the steel pipe, the locking bolt 63 is inserted into the corresponding positioning hole 62 and fixed again. In this way, the length of the device can be flexibly adjusted to adapt to steel pipes of different lengths.

[0026] Working principle: when a steel structure lifting clamp is used, first adjust the fixing structure 6 according to the length of the steel pipe, loosen and pull out the locking bolts 63 on both sides, then pull out the second support rod 2 from the first support rod 1 to a certain length, and after determining that it meets the steel pipe length, insert the locking bolts 63 according to the corresponding positioning holes 62 and fix it again, so that the length of the device can be flexibly adjusted. Subsequently, when lifting and clamping the steel pipe, the steel pipe is placed under the first support rod 1, and the steel pipe is clamped and fixed by adjusting the clamping structures 3 on the left and right sides. By respectively twisting the handles 33 on both sides, it drives the threaded rod 32 to rotate. Due to the limitation of the two limit rods 35 on the side, the threaded rod 32 can drive the vertical plate 34 to move horizontally, so that the lower arc plate 37 can extend into both sides of the steel pipe, and the arc surfaces of the two arc plates 37 are tightly attached to the upper inner wall of the steel pipe, clamping and fixing are achieved from both sides, and finally the hook 5 is connected to the crane to achieve the lifting function.
