[0002] With the rapid development of science and technology in my country and the continuous improvement of the level of architecture, novel and unique buildings have become places where people like to check in and try, such as suspended glass bridges and suspended balconies. In particular, the suspended balcony, whose design protrudes from the entire floor, allows people standing on it to better feel the suspension and unobstructedness, and is therefore loved by people.

[0003] At present, there are two main installation methods for cantilever steel structure balconies. One is to use the traditional steel pipe fastener structure system for construction. This method meets the needs of ground-floor buildings. For high-rise buildings, it not only has a long construction period, but also poses a safety hazard. The other is that workers use a hanging basket to drill holes and install brackets, and then use a tower crane to hoist the pre-welded cantilever steel structure platform to the corresponding position before installing it. This method can fully meet the installation needs of cantilever steel structures in high-rise buildings.

[0004] However, the construction and installation period of the hanging basket is long and is greatly affected by the weather. Construction cannot be carried out when the wind speed is above level 5. The restrictions are high, which in turn affects the construction period and construction efficiency. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1 to Figure 5 As shown, the present embodiment aims to provide another installation platform for installing a cantilever steel structure platform, so as to reduce the problem that the existing hanging basket installation is greatly affected by wind force. To this end, the cantilever steel structure installation platform provided in the present embodiment includes a first main beam 1 and a second main beam 2 whose ends are used to be fixed on the building floor. In the art, the end used to be fixed on the building floor is also called the head end, which is fixed to the building floor by anchor bolts. This structure is applied to the existing cantilever unloading platform. For this reason, it is not described in detail in the present embodiment.

[0024] The first main beam 1 and the second main beam 2 are arranged at intervals, and a walking passage 5 is arranged below the first main beam 1 and the second main beam 2. Since the anchor bolts and the brackets need to be installed below the building floor, the walking passage 5 is arranged below the main beam. In this embodiment, the passage refers to a base frame and a base plate arranged on the base frame, and guardrails are arranged on both sides of the base plate to form a rectangular passage.

[0025] An installation channel 6 is provided at one end of the walking channel 5 away from the building, the installation channel 6 is provided at a vertical angle to the walking channel 5, and the installation channel 6 is provided horizontally with the walking channel 5. At the same time, a steel cable connecting ring 4 is provided at one end of the first main beam 1 and the second main beam 2 away from the building and at both ends of the installation channel 6. The steel cable connecting ring 4 is used to connect the steel cable to form a safety protection for the entire platform.

[0026] In this way, through the above-mentioned settings, the installation of wall rivets can be realized. The length of the walking channel 5 is based on the positions of the first main beam 1 and the second main beam 2. For example, the first main beam 1 and the second main beam 2 are installed at the positions of the side windows, and the cantilevered steel structure platform needs to be installed at the position of the main window, which is set at an angle. At this time, the walking channel 5 needs to be longer.

[0027] Considering the height of an adult, if the height of the walking channel 5 is set too high, the volume of the entire platform will be too large. For this reason, in this embodiment, a lifting cylinder 51 is provided on the walking channel 5. The lifting cylinder 51 is provided on both sides of the end of the walking channel 5, that is, four lifting cylinders 51 are provided. At the same time, a connecting plate 3 is provided between the first main beam 1 and the second main beam 2. The connecting plate 3 is arranged between the first main beam 1 and the second main beam 2 at intervals, and the piston end of the lifting cylinder 51 is fixedly connected to the connecting plate 3. In this way, since the first main beam 1 and the second main beam 2 are in a fixed state, the lifting cylinder 51 acts, so that the walking channel 5 will move downward, thereby adjusting the distance between the walking channel 5 and the first main beam 1 and the second main beam 2, thereby reducing the volume of the entire platform.

[0028] In order to facilitate the tower crane lifting, in this embodiment, the installation channel 6 can be flipped and set at the end of the walking channel 5. The purpose is to flip the installation channel 6 to the bottom of the walking channel 5 so that the horizontal vertical adjustment is vertical, so that the area in the horizontal direction becomes smaller, thereby facilitating lifting. To this end, in this embodiment, the installation channel 6 can be flipped and set at the end of the walking channel 5 through a flip mechanism 7. Specifically, the flip mechanism 7 includes a flip plate 71 set at the end of the walking channel 5 and a flip cylinder 72 set on the flip plate 71. One end of the installation channel 6 close to the walking channel 5 is hinged to the flip plate 71, and the output end of the flip cylinder 72 is hinged to the bottom of the installation channel 6. In this way, under the action of the flip cylinder 72, the installation channel 6 is flipped 90°, thereby facilitating lifting.

[0029] Taking into account that the cantilever steel structure platform may be installed on the left side or the right side of the main beam, a steering mechanism 8 for installing the steering of the channel 6 is also provided at the bottom of the walking channel 5 for the convenience of installation. The steering mechanism 8 includes a steering plate 81 provided at the bottom of the walking channel 5 and a connecting universal joint 82 provided on the steering plate 81. The universal joint is also called a shaft coupling. A steering cylinder 83 is provided at the end of the connecting universal joint 82 away from the steering plate 81. The output end of the steering cylinder 83 is connected to a steering universal joint 84. The end of the steering universal joint 84 away from the steering cylinder 83 is fixed on the flip plate 71. At the same time, bogies 85 are provided on both sides of the steering cylinder 83. A placement groove 851 is provided at the end of the bogie 85 close to the flip plate 71. A steering shaft 86 matching the steering groove is provided on the flip plate 71. A limiting plate 87 for limiting the steering shaft 86 is provided on the bogie 85. The limiting plate 87 is telescopically arranged above the placement groove 851. Specifically, a pushing cylinder 88 is provided on the bogie 85, and the power end of the pushing cylinder 88 is connected to the limit plate 87. Of course, it is also possible not to rely on the limit plate 87, and the power end of the pushing cylinder 88 only needs to be above the steering shaft 86. In this way, when the pushing cylinder 88 on one side of the steering cylinder 83 works, when the steering cylinder 83 works, the flip plate 71 will rotate around the steering shaft 86 on this side, so that left and right switching can be achieved.

[0030] In order to further ensure safety, an electromagnet is provided on the side of the walking channel 5, and a magnetic attraction part matching the electromagnet is provided at the end of the installation channel 6. In this way, the entire installation channel 6 is triple-fixed by the steel cable, the steering cylinder 83 and the electromagnet, thereby ensuring safety in use.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
