When the climbing frame 21 is limited at the structural layer corresponding to the main structure 10, the operation platform 23 provides a construction operation platform for constructors, that is, the constructors can stand on the operation platform 23 to construct the elevator shaft, and the operation platform 23 can be adjusted to a required operation height through lifting adjustment, so that any height range in the elevator shaft can be completely covered.
In one embodiment, as shown in fig. 2, a fall arrest beam 212 for supporting the work platform 23 is provided on the climbing frame 21 below the bottom of the work platform 23. The anti-falling beam 212 is arranged below the working platform 23 at a certain distance, so that the falling platform can be caught when the working platform falls accidentally, and the construction safety is ensured.
Preferably, the working platform 23 protrudes outward from the side of the anti-falling beam 212, so that the anti-falling beam 212 can catch the working platform 23.
In one embodiment, as shown in fig. 1 and 3, a lifting mechanism 22 is disposed on the climbing frame 21 above the top of the working platform 23, the lifting mechanism 22 is connected to the working platform 23 through a suspension cable 221, and the lifting mechanism 22 controls the lifting of the working platform 23.
Preferably, the lifting mechanism 22 further comprises a lifting block 222, a part of the suspension cable 221 is wound on the lifting block 222, and an end of the suspension cable 221 is fixedly connected to the lifting block 222, so that the suspension cable 221 is wound on the lifting block 222 or the wound suspension cable 221 is partially paid out by the lifting block 222, thereby achieving the effect of lifting or lowering the work platform 23.

Due to the position of the position-limiting member 232, the second end 2312 of the rotary bearing 231 can only rotate upwards from the position-limiting member 232 and cannot rotate downwards. Thus, when the work platform 23 is adjusted to be lifted, the overhanging end 2311 of the rotary support 231 is abutted to the corresponding portion of the main structure, so as to drive the overhanging end 2311 of the rotary support 231 to rotate downwards, the second end 2312 rotates upwards, and the work platform 23 can be further lifted upwards to pass through the corresponding portion of the main structure, and when the work platform 23 is stopped at the corresponding position of the main structure, the rotary end 2311 of the rotary support 231 can be rotated upwards to be horizontal and then placed at the corresponding portion of the main structure.

When the climbing frame 21 is limited at the structural layer corresponding to the main structure 10, the operation platform 23 provides a construction operation platform for constructors, that is, the constructors can stand on the operation platform 23 to construct the elevator shaft, and the operation platform 23 can be adjusted to a required operation height through lifting adjustment, so that any height range in the elevator shaft can be completely covered.
In a specific embodiment, the method further comprises the following steps: as shown in fig. 1 and 2, a falling prevention beam 212 corresponding to the lower part of the bottom of the work platform 23 is mounted on the climbing frame 21 to support the falling work platform 23 by the falling prevention beam 212. The anti-falling beam 212 is arranged below the working platform 23 at a certain distance, so that the falling platform can be caught when the working platform falls accidentally, and the construction safety is ensured. Preferably, the working platform 23 protrudes outward from the side of the anti-falling beam 212, so that the anti-falling beam 212 can catch the working platform 23.
In a specific embodiment, the method further comprises the following steps: as shown in fig. 1 and 3, a lifting mechanism 22 is provided, the lifting mechanism 22 is mounted on the climbing frame 21, the lifting mechanism 22 is connected to the work platform 23 through a suspension cable 221, and the lifting of the work platform is controlled by the lifting mechanism 22.
In a specific embodiment, the method further comprises the following steps: as shown in fig. 3 and 4, a rotary support 231 is provided, the rotary support 231 is rotatably mounted on the side of the work platform 23, a first end of the rotary support 231 protrudes out of the work platform to form an overhanging support end 2311, and a second end 2312 of the rotary support 231 is located on the side of the work platform 23;
providing a limiting member 232, installing the limiting member 232 at a side portion of the working platform 23 and corresponding to the second end 2312 of the rotating support 231, and limiting the second end 2312 of the rotating support 231 to rotate downward through the limiting member 232;
when the work platform 23 is lifted to the corresponding structural beam of the main structure 10, the rotary bearing 231 is rotated to be supported on the structural beam, and the second end 2312 of the rotary bearing 231 is placed on the stopper 232.
The rotary support 231 is supported at the corresponding position of the main structure, so that stable support can be provided for the working platform 23, and the working platform 23 is ensured to be kept stable. Due to the position of the position-limiting member 232, the second end 2312 of the rotary bearing 231 can only rotate upwards from the position-limiting member 232 and cannot rotate downwards. Thus, when the work platform 23 is adjusted to be lifted, the overhanging end 2311 of the rotary support 231 is abutted to the corresponding portion of the main structure, so as to drive the overhanging end 2311 of the rotary support 231 to rotate downwards, the second end 2312 rotates upwards, and the work platform 23 can be further lifted upwards to pass through the corresponding portion of the main structure, and when the work platform 23 is stopped at the corresponding position of the main structure, the rotary end 2311 of the rotary support 231 can be rotated upwards to be horizontal and then placed at the corresponding portion of the main structure.
In a specific embodiment, the method further comprises the following steps: installing a jump elevator below the climbing frame 21; a driving mechanism 216 is provided, the driving mechanism 216 is installed at the bottom of the climbing frame 21, the driving mechanism 216 is connected with the jump elevator, and the jump elevator is driven to ascend and descend by the driving mechanism 216.
While the present invention has been described in detail and with reference to the embodiments thereof as illustrated in the accompanying drawings, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Therefore, certain details of the embodiments are not to be interpreted as limiting, and the scope of the invention is to be determined by the appended claims.
