There are various types of cages to adapt to different application scenarios and needs. Cages are widely used in the construction of high-rise buildings, including concrete pouring, brick and tile laying, steel structure installation, etc. When using a cage, safety regulations and operating guidelines must be strictly followed to ensure safe construction. Before use, the cage should be fully inspected to ensure that its structure is complete, the connection is firm, and the safety device is effective. The operator should be professionally trained and familiar with the performance and operation methods of the cage.

[0043] In the present technical solution, when the construction personnel walk from the walking assembly 300 to the top of the lifting assembly 200, the traction machine 204 works to move the lifting chamber 207 to the top of the lifting frame 201. At this time, the first hatch 304 is opened, and the construction personnel enter the lifting chamber 207 from the first hatch 304. The traction machine 204 works to drive the traction wheel 205 to work, so that the traction rope 206 on the traction wheel 205 moves to move the lifting chamber 207 downward, thereby driving the construction personnel to move to the bottom of the lifting frame 201. The bottom of the lifting frame 201 is provided with a support seat 208 and a damper 20 9, can play the buffering function of the lifting chamber 207, and play the buffering protection function in case of sudden falling.

[0045] In the present technical solution, a reinforcing plate 202 is provided at the bottom of the lifting frame 201 to realize the installation of the frame 401, and support plates 402 and support ribs 403 are provided on both sides of the frame 401 to realize further stable installation of the frame 401, thereby ensuring the structural performance of the frame 401. When the construction personnel stand on the platform 414, the driving motor 405 is started to drive the driving shaft 406 to rotate at the bottom of the frame 401. When the driving shaft 406 rotates, the gear 407 and the winding wheel 408 are driven to rotate synchronously. The transmission of the gear 407 causes the two driving shafts 406 to rotate synchronously inside the frame 401. Through the setting of the guide wheel 410, when the pull rope 409 is pulled on the surface of the guide wheel 410, the winding wheel 408 winds up and pulls the pull rope 409 to move, thereby driving the platform 414 to rise, so that the platform 414 drives the construction personnel to be lifted and lowered, and the construction personnel on the platform 414 are lifted to a suitable position, so as to facilitate the construction processing of the bottom of the steel box girder 105.

The platform 414 is provided with gaps for the movement of the pull rope 409 around, and the platform 414 is slidably connected to the inside of the frame 401; the bottom of the frame 401 is fixedly connected to a support platform 413 The support platform 413 is symmetrically arranged on both sides of the driving motor 405, and the controller of the driving motor 405 is electrically connected to the pressure sensor 419. The support platform 413 is correspondingly arranged below the platform 414, and the top surface of the support platform 413 and the top surface of the support seat 208 are located at the same horizontal position. Side panels 415 are fixedly installed on both sides of the top surface of the platform 414, and the side panels 415 are respectively fixedly connected to the two ends of the crossbeam 421 and several guardrails 422, and the crossbeam 421 and the guardrail 422 are both located on one side of the construction area 404.

[0047] In the present technical solution, a support platform 413 is provided at the bottom of the frame 401 for supporting the platform 414, which can reduce the vibration of the platform 414 when it descends and improve the safety protection performance. When the platform 414 moves, it slides on the surface of the guide plate 411. The auxiliary guidance is achieved by the setting of the guide plate 411 to improve the stability during the movement. After the platform 414 moves to the appropriate position, the electromagnetic coil 412 under the platform 414 is charged so that the armature inside it is extended under the influence of the magnet. At this time, the bottom of the platform 414 is limited. When the platform 414 suddenly falls, it can play a limiting role to avoid the abnormal landing of the platform 414 and improve the safety performance. A crossbeam 421 is provided on one side of the platform 414 for the installation of a safety buckle, and a guardrail 422 is provided for auxiliary protection.

[0049] In the present technical solution, after the lifting and lowering adjustment of the platform 414 is completed, the electric push rod 418 is started at the same time, and the electric push rod 418 is extended to drive the support rod 417 to rotate around its middle, and one end of the support rod 417 is clamped between the two mutually meshing gears 407, thereby realizing the locking of the gear 407, further ensuring the safety performance of the platform 414. When the construction workers stand on the construction platform 420, the pressure sensor 419 detects the gravity signal and transmits the gravity signal to the controller of the drive motor 405. At this time, when the drive motor 405 is started, the platform 414 cannot be driven to rise and fall, so that the construction workers are prevented from lifting and lowering the platform 414 during the construction process, which is used to protect the safety of the construction workers located in the construction area 404, so that all the construction workers can be evacuated to a safe area before the platform 414 is lifted and lowered, which can improve the safety performance and avoid the problem of construction workers being squeezed by the construction area 404 during lifting and lowering. The lifting of the platform 414 drives the construction workers to move to the side wall of the steel box girder 105, which is convenient for construction operations.
