One end of the double-row load-bearing slanting rods is placed on the wall of the elevator shaft, and the other end is placed on the floor panel, and is fixed with a jacking bracket, and can climb up with the floors. The inclination angle between the double-row load-bearing slanting bars and the ground plane is 30°-40°. Safety nets are arranged on the double-row load-bearing diagonal bars. The anti-slip vertical rods of the load-bearing system can effectively prevent the frame from slipping inwards and enhance the overall stability of the derrick.

The protective system consists of a safety net, a top protective plate and an artificial cover plate fixed on the top protective plate by hinges. The setting of the protection system provides safety protection for the construction personnel when climbing and working inside and outside the frame, and the construction personnel can also reach the construction level through the artificial cover with hinges.

The support system is composed of a support bar composed of upright bars and cross bars arranged in a criss-cross arrangement, and a jacking bracket 2 for fixing the cross bars on the elevator shaft wall and floor deck. The poles are arranged at the four corners of the elevator shaft and are 150-250 mm away from each side wall. The horizontal bar of the support system is fixed with the wall and the floor plate by jacking brackets, which is convenient for removing the fixed points when climbing.

The climbing system consists of steel ladders and hoisting rings. The steel ladder setting of the climbing system enables people to reach the construction surface from the inside of the derrick; the derrick can climb the whole frame by lifting the hoisting ring for repeated turnover.

Compared with the prior art, the utility model adopts the technology of a dual-purpose operation and protection platform in the elevator shaft. Through the technical scheme of the utility model, it not only solves the problem of safety protection for construction in the elevator shaft, but also provides operators with Temporary construction platform and safety guarantee, and can provide construction personnel with a temporary construction platform that can be climbed, and can also be used repeatedly. In addition, it has the characteristics of convenient erection and low cost, and it also has the characteristics of continuous use and easy disassembly. These features will enable it to be widely used in actual construction and have high promotional value.
