Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and specifically to a rotating platform for coiled steel bars. Background Art

[0002] Coiled steel bars are a common name in building construction, referring to steel bars with a diameter of less than 10 mm. Since steel bars with a diameter of less than 10 mm are easy to bend, in order to reduce the length before transportation, the manufacturer coils long steel bars into circular rings. Such steel bars are simply referred to as coiled steel bars on construction sites.

[0003] In the prior art, when straightening coiled steel bars at the construction site, the coiled steel bars are placed on the ground, and then a straightening machine is used to pull them. When the coiled steel bars do not move, the straightened steel bars will be distorted. Sometimes, due to excessive pulling force, "thinned steel bars" will appear, and the physical properties of the steel bars will also change (become brittle), resulting in the straightened steel bars not meeting the seismic requirements; even sometimes they are pulled off, causing injury incidents. Summary of the Invention

[0004] The purpose of the present invention is to provide a rotating platform for coiled steel bars to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A rotating platform for coiled steel bars, including a base. A turntable bearing is installed on the top surface of the base. An elastic support assembly is rotatably connected above the turntable bearing. A protection mechanism is provided above the base for protecting the bottom end of the elastic support assembly. A clamping connection member is provided between the protection mechanism and the base for limiting the protection mechanism.

[0006] Preferably, mounting blocks are integrally formed on the surface of the base. There are multiple mounting blocks, and the multiple mounting blocks are arranged and distributed along the arc side wall of the base. Bolt holes are opened on the surface of the mounting blocks.

The introduction piece has a circular arc plate-like structure. Multiple spring support pieces enclose a cylindrical structure, and multiple introduction pieces enclose a frustum structure.

[0010] Preferably, the protection mechanism includes a protective cover, which has a "convex"-shaped annular frame. The top plate of the protective cover overlaps on the fixed panel, and the bottom plate of the protective cover overlaps on the base.

[0011] Preferably, the clamping and connecting part includes a clamping groove, a clamping strip, an elastic traction piece and a first pull ring. There are four groups of clamping grooves, which are respectively distributed at the four ports of the diversion groove. Each group of clamping grooves has two, and the two clamping grooves are respectively opened on the two parallel side walls of the diversion groove.

One end of the traction rope is bolted to the surface of the first pull ring, and the other end of the traction rope passes through the perforation and is bolted to the surface of the second pull ring. The perforation is opened on the bottom plate of the protective cover. The second pull ring is fixed on the outer ring surface of the sleeve ring, and the sleeve ring is movably sleeved on the outside of the protective cover.
