Description

Technical Field

[0001] The utility model specifically relates to a self-expanding top platform. Background Art

[0002] The top platform is a commonly used load-bearing device in the current elevator installation process. In the prior art, the left beam and the right beam of the platform are an integral body, and the beam is driven to expand and contract by a lead screw exposed in the middle. The lead screw exposed in the middle is often contaminated by cement due to cross-operation at the construction site; the expansion and contraction dimensions are affected by different resistances of the left and right beams, resulting in unequal expansion and contraction dimensions of the left and right beams; moreover, during the handling process, due to its large weight and external dimensions, it is easily restricted by the site and inconvenient to handle. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a self-expanding top platform aiming at the deficiencies of the prior art, which can well solve the above problems.

[0004] To meet the above requirements, the technical solution adopted by the utility model is: to provide a self-expanding top platform, which includes two horizontally arranged telescopic beams; two vertical columns are respectively arranged on both sides of the front end of the telescopic beam, one end of the platform tie rod is respectively connected to the top of the column, the other end of the platform tie rod is connected to the rear end of the telescopic beam, a rear springboard is covered above the front ends of the two telescopic beams, at least five small springboards are covered above the rear ends of the two telescopic beams, and the inner end faces of the two telescopic beams are connected by a connecting pipe; two vertical lower brackets are connected to the tops of the two telescopic beams, a vertical upper bracket is connected to the top of each lower bracket, and a heightening bracket is connected to the top of each upper bracket; it also includes two bracket diagonal bracing parts, the tops of the two bracket diagonal bracing parts are connected to the side end faces of the upper bracket, and the bottoms of the two bracket diagonal bracing parts are connected to the side end faces of the lower bracket; it also includes two heightening bracket diagonal bracing parts, the tops of the two heightening bracket diagonal bracing parts are connected to the top side end faces of the heightening bracket, and the bottoms of the two heightening bracket diagonal bracing parts are connected to the bottom side end faces of the heightening bracket; a horizontally arranged upper springboard is fixed to the top of the heightening bracket, and a handrail is arranged at the edge above the upper springboard.

[0005] The advantages of the self-expanding top platform are as follows:

[0006] The self-expanding top platform decomposes the left beam and the right beam in the prior art into two independent units connected by connecting pipes. The left beam and the right beam are driven by their respective lead screws to solve the situation where the telescopic dimensions of the left and right beams are not equal. Moreover, the lead screws of the new platform are hidden in the middle of the beams to avoid contamination by foreign objects. The left and right beams of the independent units are smaller in size and weight, making them more convenient for transportation and handling. The columns of the self-expanding top platform are composed of two different square pipes instead of a single integral channel steel in the original platform. The small square pipe is usually hidden inside the large square pipe and extended when in use, which also facilitates transportation and handling. Brief Description of the Drawings
