An extension control component 2 is installed on the side of the main body 1 of the inclined support operation steel platform, and a blocking and protecting component 3 is connected to the top of the main body 1 of the inclined support operation steel platform. And a hoisting control component 4 is arranged on the side of the blocking and protecting component 3; The extension control component 2 includes an extension platform 201. The extension control component 2 is convenient for filling the gap between the steel platform and the elevator shaft. The extension platform 201 forms a detachable structure with the main body 1 of the inclined support operation steel platform through a control groove 202 and an insertion rod 207. And the insertion rod 207 forms an elastic structure with a fixed seat 205 through a first spring 206. Mounting holes 204 are equidistantly arranged inside a mounting plate 203. The extension platform 201 forms a sliding structure with the main body 1 of the inclined support operation steel platform, and two extension platforms 201 are symmetrically arranged about the vertical central axis of the main body 1 of the inclined support operation steel platform; By placing the main body 1 of the inclined support operation steel platform in the elevator shaft, it can be used to replace the scaffolding for installation. At the same time, after the construction of this floor is completed, the main body 1 of the inclined support operation steel platform can be directly hoisted to the next floor by a crane. At the same time, when the main body 1 of the inclined support operation steel platform does not match the elevator shaft, the extension platform 201 can be pulled to block the gap of the elevator shaft, and the device can be fixed through the mounting plate 203 and mounting holes 204 on the side of the extension platform 201, increasing the practicability of the device.

[0028] Please refer to Figure 1 And Figure 4As shown in the figure, there is a lift shaft lifting type diagonal bracing operation steel platform, and the blocking and protecting component 3 includes a support rod 301. The blocking and protecting component 3 can prevent sundries from falling from the upper layer and causing casualties. The protecting plate 303 forms a detachable structure with the support rod 301 through a rotating rod 306 and a support block 304, and the protecting plate 303 forms a rotating structure with the support rod 301 through a first rotating shaft 302, and the rotating rod 306 forms a rotating structure with the protecting plate 303 through a rotating seat 305. When personnel are constructing inside the lift shaft on the diagonal bracing operation steel platform main body 1, the protecting plate 303 can prevent objects from falling from the upper part of the lift shaft and causing casualties. At the same time, the protecting plate 303 can be disassembled and rotated to use a crane to hoist the diagonal bracing operation steel platform main body 1, which is simple to operate and convenient to use.

[0029] Please refer to Figure 1 and Figure 5 As shown in the figure, there is a lift shaft lifting type diagonal bracing operation steel platform, and the hoisting control component 4 includes a fixed block 401. The hoisting control component 4 is convenient for using a crane to hoist the steel platform and adjusting its height to construct different floors. The movable hook 404 forms an elastic structure with the fixed hook 402 through a second spring 405, and the movable hook 404 forms a rotating structure with the fixed hook 402 through a second rotating shaft 403. The diagonal bracing operation steel platform main body 1 can be hoisted by using a crane and clamping the connecting ring between the fixed hook 402 and the movable hook 404. At the same time, under the action of the self-elastic force of the second spring 405, the movable hook 404 can be prevented from disengaging from the fixed hook 402, so as to ensure the stability of the crane hoisting the diagonal bracing operation steel platform main body 1.

[0030] Working principle: First, install the diagonal bracing operation steel platform main body 1 in the lift shaft to be constructed. According to the sizes of the diagonal bracing operation steel platform main body 1 and the lift shaft, the insertion rod 207 can be pulled. At this time, the insertion rod 207 will squeeze the first spring 206 and retract into the fixed seat 205. At this time, the extension platform 201 can be pulled, and the extension platform 201 will extend from the diagonal bracing operation steel platform main body 1, so as to fill the gap between the diagonal bracing operation steel platform main body 1 and the lift shaft. And the device can be installed by using the installation holes 204 inside the installation plate 203. Release the insertion rod 207, and under the action of the self-elastic force of the first spring 206, the insertion rod 207 can be pushed out of the fixed seat 205 and inserted into the control groove 202 at the top of the extension platform 201, so as to fix the extension platform 201 and the diagonal bracing operation steel platform main body 1. Then, the protecting plate 303 can be rotated, and at the same time, the rotating rod 306 can be rotated, and the rotating rod 306 can be inserted into the support block 304. At this time, the protecting plate 303 can be kept in a horizontal position to protect the diagonal bracing operation steel platform main body 1, that is, the personnel.

[0031] Next, after the construction of this floor is completed, the protective plate 303 can be rotated again. At the same time, rotate the rotating rod 306 to disengage it from the support block 304. At this time, the protective plate 303 can be rotated to the vertically downward position. Then, disassemble the installation points of the device. At this time, press the movable catch 404, engage the fixing ring connected to the crane on the fixed catch 402, and at the same time release the movable catch 404. Under the action of the self-elastic force of the second spring 405, the movable catch 404 can be pushed to rotate and make it abut against the fixed catch 402. At this time, the device can be lifted to the next floor by using the crane.
