[0040] The column guide frame 2 is fixedly mounted on the platform base 1, and the climbing device is mounted on the column guide frame 2. To improve the stability of the lifting platform, the column guide frame 2 is also connected to the outer wall of the building through a wall support 3;

[0041] The working platform is fixedly connected to the climbing device, and the working platform includes a plurality of telescopic platform components, and the telescopic platform components include a scaffolding board 4 and at least one telescopic beam structure, and the installation space of the scaffolding board 4 can be expanded through the telescopic beam structure;

[0042] The multiple telescopic platform components are divided into two groups, which are respectively located on both sides of the climbing device. The number of telescopic platform components can be adaptively selected according to actual conditions;

[0043] Specifically, the telescopic crossbeam structure includes a main body 5 and an expansion part 6 located in the main body 5, that is, the expansion part 6 is inserted into the main body 5, and the main body 5 is fixedly connected with a scaffolding board 4. In the expanded state, the expansion part 6 is fixedly connected with an expansion board 7. If it is not in the expanded state, the expansion part 6 is located in the main body 5, and the expansion board 7 is not needed at this time;

[0044] In order to fix the extended extension part 6, a fastener is also installed on the main body 5. The fastener can be a screw. The screw is threadedly connected to the extension part 6, and its end abuts against the extension part 6 to complete the fixation.

[0045] In addition, the telescopic platform assembly of the present embodiment further comprises a longitudinal beam frame 8, which is fixedly connected to the lower side of the main body 5, and the longitudinal beam frame 8 is used to connect with the longitudinal beam frame 8 of the climbing device or the adjacent telescopic platform assembly;

Both ends of any longitudinal beam are provided with mounting holes to facilitate fixed connection with the longitudinal beams of the adjacent longitudinal beam frame 8 by bolts;

[0047] The number of telescopic beam structures on the lower side of any scaffolding board 4 is multiple, and two are taken as an example in this embodiment. In order to limit the expansion board 7, at least two limit blocks 9 are fixedly connected to the bottom side of the expansion board 7. In this embodiment, two limit blocks 9 are taken as an example.

The specific installation method can be adapted and installed by those skilled in the art according to common knowledge. The total weight of the working platform is applied to the rack 17 of the column guide frame 2. Therefore, by directly measuring the weight of the overall structure of the column guide frame 2 and subtracting the known weight of the column guide frame 2 from the result, the total weight of the lifting platform and the climbing device can be obtained, so that the total weight of the operating personnel, operating tools and building materials on the working platform can be more accurately monitored, and the load of the working platform can be effectively monitored, which helps construction personnel better understand the working status of the working platform and avoids work safety problems.

[0065] Embodiment 4

[0066] Based on the second embodiment, the weight monitoring scheme of the attached work platform of this embodiment is as follows:

[0067] The difference from the third embodiment is that the weighing sensor 18 of this embodiment is installed in the through hole 21 on the power plate 13, directly in contact with the upper side of the connecting shaft 19, so that the force applied by the connecting shaft 19 on the sensitive unit of the sensor 18 can be directly obtained, and the corresponding weight data can be obtained by calculation, which can also effectively realize the monitoring of the platform load.

[0068] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit and essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0069] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
