[0031] In order to solve the problems existing in the prior art, therefore, the embodiment solves the problems by the following technical scheme. A cantilever scaffold side anchor steel beam dismantling operation platform is provided with a steel beam fixing main clamp 11 and a U-shaped anti-extraction pin 12. The steel beam fixing main clamp 11 is arranged at the lower end of a platform unit one 1, a platform middle unit 2 and a platform unit two 3 respectively, and is composed of a clamp support column 1101, a bottom sliding lifting platform 1102, a stable lifting connecting piece 1103, a connecting bolt 1104, a clamp adjusting bolt 1105 and a clamp adjusting nut 1106. The clamp support column 1101 is provided with an opposite sliding groove in the length direction of the platform. The bottom sliding lifting platform 1102 is fixed on the clamp support column 1101 by penetrating the sliding groove through the connecting bolt 1104. The rear side of the bottom sliding lifting platform 1102 is provided with a lifting hole. The top surfaces of the two sides of the front end of the bottom sliding lifting platform 1102 are provided with anti-extraction pin insertion openings. The anti-extraction pin insertion openings are inserted with the U-shaped anti-extraction pin 12. The stable lifting connecting piece 1103 is arranged between the tail of the connecting bolt 1104 and the clamp support column 1101. The bottom of the clamp adjusting bolt 1105 is located in the lifting hole. The clamp adjusting nut 1106 is vertically perpendicular to the platform surface layer. As shown in Figs. Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , the clamp support column 1101 is provided with a sliding groove on one side. The bottom sliding lifting platform can be fixed on the clamp support column 1101 by penetrating the sliding groove through the connecting bolt 1104. The stable lifting connecting piece 1103 is arranged between the tail of the connecting bolt 1104 and the clamp support column 1101. The stable lifting connecting piece 1103 reduces the friction with the clamp support column 1101 and enables the two bolts to be stably lifted horizontally. The lifting operation is more smooth. The rear side of the bottom sliding lifting platform 1102 is provided with a lifting hole. The bottom of the clamp adjusting bolt 1105 is located in the lifting hole. The clamp adjusting nut 1106 is vertically perpendicular to the platform surface layer. The rotation of the clamp adjusting bolt 1105 in the clamp adjusting nut 1106 can control the lifting of the platform, clamp the side anchor cantilever steel beam, and is safe and efficient. In addition, the top surfaces of the two sides of the front end of the bottom sliding platform 1102 are provided with anti-extraction pin insertion openings. When the clamp pulls up the short-leg cantilever steel beam 8, the U-shaped anti-extraction pin 12 is inserted into the anti-extraction pin insertion openings through the platform surface layer, so as to prevent the platform module from sliding out of the steel beam and causing hidden dangers.

[0032] The platform unit is provided with two groups of steel beam fixing main clamps 11 according to the spacing of the steel beams. The front end clamps and the main clamps bear the limitation of horizontal displacement and left and right displacement operation. The component design and use steps are consistent with those of the steel beam fixing main clamp 11. The platform middle unit is the same as other module components in terms of platform enclosure guardrails 5, so that it can be more conveniently used as an intermediate expansion module and assembled with other modules.

[0033] The operation platform structure is stable, safe and efficient, not only improves the operation environment of the operation personnel when the side anchor cantilever steel beam is demolished, but also reduces the engineering operation safety hidden danger, improves the operation efficiency, protects the occupation health of the front-line operation personnel, and all the operation platforms are decomposed and recycled to the indoor or hoisted and transported to the lower floor after the side anchor cantilever steel beam is demolished, the operation platform is arranged to be decomposed and cleaned by the special person after the operation platform is demolished, and is registered and stored for circulation, which meets the industry demand of assembly type and high circulation.

[0034] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
