Description

Technical Field

[0001] The utility model relates to the technical field of aerial work platforms, in particular to an inclined column operating platform for steel structure installation. Background Art

[0002] During the installation and welding of steel columns, an operating platform needs to be set up to provide operating space for the entire operation process. The operating platform is usually directly located on the steel beam bracket reserved for the operating steel column. For steel columns without steel beam brackets, the current conventional method to set up an operating platform is to weld a temporary tripod-shaped bracket on the column body, and then place the platform on top of the temporary bracket. The main problems and defects of this method are as follows:

[0003] 1. The bottom of the operating platform must have enough components to support the operating platform before it can be placed directly on top;

[0004] 2. Since the temporary tripod must be welded to the column before the steel column is hoisted, the work before the steel column is hoisted increases the working time;

[0005] 3. After the operating platform is removed, the temporary tripod at the bottom must be cut using additional measures, increasing the investment in measures;

[0006] 4. Welding and cutting of temporary tripods will damage the paint on the steel column, increasing the on-site paint repainting process and costs. Utility Model Content

[0007] The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a tilting column operating platform for steel structure installation which can reduce the preparation work before lifting, reduce manpower, reduce the scope of paint touch-up, improve work efficiency and has high applicability.

[0008] The utility model is realized by the following technical scheme: an inclined column operating platform for steel structure installation, comprising:

[0009] The bottom surface of the platform is parallel to the horizontal plane, and the bottom surface of the platform is provided with mounting holes adapted to the steel column;

[0010] Guardrails, the guardrails are arranged around the bottom surface of the platform;

[0011] Hanging lug plates, the four corners of the bottom surface of the platform are respectively provided with the hanging lug plates;

[0012] A hanging hole, wherein the hanging hole is arranged on a hanging ear plate, and the hanging ear plate is arranged on a steel column;

[0013] A steel wire rope is connected between the hanging ear plate and the hanging hole.

[0014] Furthermore, two ends of the steel wire rope are respectively fixed to the hanging ear plate and the hanging hole through rope clamps.

[0015] Furthermore, the platform bottom surface and the guardrail are grid structures respectively.

[0016] Furthermore, the diameter of the steel wire rope is 14 mm.

[0017] Furthermore, the hanging ear plate has an L-shaped structure, the vertical section of the hanging ear plate is provided with a rope threading hole, the horizontal section of the hanging ear plate and the bottom surface of the platform are welded to each other, and the welding surface between the hanging ear plate and the bottom surface of the platform is a right-angle surface formed by two adjacent surfaces.

[0018] Furthermore, a level is provided on the top side of the bottom surface of the platform.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The utility model arranges hanging ear plates at the four corners of the bottom surface of the platform, opens hanging holes on the hanging ear plates of the steel column, connects steel wires between the hanging holes and the hanging ear plates, and thus the operating platform is installed on the steel column in a hanging manner through the steel wires. There is no need to weld temporary brackets, which can reduce the work preparation work before the steel column is hoisted, and eliminates the investment in manpower and measures for the brackets during the later cutting due to the welding of temporary brackets, and eliminates the damage to the paint on the steel column 13 due to the welding of temporary brackets, thereby reducing the scope of paint touch-up.

[0021] 2. Since the operating platform is suspended on the steel column by a steel wire rope, the length of the steel wire rope can be adjusted. Therefore, the utility model can suspend the operating platform on a vertical steel column or on an inclined steel column, and has high applicability.

[0022] 3. By setting a level on the top side of the bottom surface of the platform and observing the bubble position of the level, the stability of the bottom surface of the platform can be dynamically monitored to determine whether the bottom surface of the platform is parallel to the horizontal plane.
