Description

Retractable platform for self-climbing tower cranes Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a telescopic platform for a self-climbing tower crane. Background Technology

[0002] Traditional self-climbing tower cranes are attached to building structures via support frames. Each support frame is connected to the building structure through two main supports, two horizontal supports, and two lower supports. To allow crane operators and workers to access the crane, simple access paths are often provided on the main supports. In existing technology, when cutting, welding, installing, or dismantling the main support supports, workers often need to suspend temporary hanging baskets on both sides of the main support and stand on them to perform the operations, which is inconvenient and requires constant disassembly and reassembly of the hanging baskets to reposition them, making the process cumbersome. Therefore, we propose a retractable platform for self-climbing tower cranes to solve the above problems. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a retractable platform for self-climbing tower cranes, which solves the problem of cumbersome and inconvenient operation caused by repeated disassembly and assembly.

[0004] This invention is achieved through the following scheme: a retractable platform for a self-climbing tower crane, connected to one end of a support frame near the building structure, providing a foothold for workers to perform construction on two main supports. The retractable platform includes: a suspended platform, fixedly connected to the end of the support frame near the building structure; a first platform, fixedly connected to the lower end of the suspended platform and located below the two main supports, extending in a direction toward the building structure; a retractable and adjustable connector, one end connected to the first platform and the other end facing the building structure; and a second platform, fixedly connected to the other end of the connector, wherein the extension or retraction of the connector can control the second platform to move away from or closer to the first platform. Both the first and second platforms are horizontally positioned for workers to stand on.

[0005] A further improvement of the telescopic platform for the self-climbing tower crane of the present invention is that the connecting member includes a sleeve and a connecting rod, the sleeve is fixed to one of the first platform and the second platform, one end of the connecting rod is slidably inserted into the sleeve, and the other end is fixedly connected to the other of the first platform and the second platform; the connecting member also includes a locking member for fixing the sleeve and the connecting rod.

[0006] A further improvement of the retractable platform for the self-climbing tower crane of the present invention is that the number of the connecting parts is multiple, and the multiple connecting parts are arranged at intervals along the width direction of the first platform.

[0007] A further improvement of the retractable platform for the self-climbing tower crane of the present invention is that a third platform is connected to both ends of the second platform in the width direction, and the third platform has at least a first flip position and a second flip position compared to the second platform. When the third platform is flipped to the first flip position, the third platform is extended to the outside of the main support. When the third platform is flipped to the second flip position, the third platform is retracted to the inside of the main support.

[0008] A further improvement of the telescopic platform for the self-climbing tower crane of the present invention is that the third platform is in a horizontal state when flipped to the first flipping position, and in a vertical state when flipped to the second flipping position.

[0009] A further improvement of the telescopic platform for the self-climbing tower crane of the present invention is that the hanging plate is connected and fixed to the support frame by bolts.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting up a first platform and a second platform for workers to stand on, it is convenient for workers to move back and forth to carry out construction on the main support. Moreover, by setting up a telescopic and adjustable connector, the second platform can be controlled to move away from or closer to the first platform, thereby adjusting the usable area of ​​the entire platform and expanding the construction range. It can be flexibly adjusted according to the working conditions. Attached Figure Description

[0017] To address the problem of cumbersome and inconvenient operation caused by repeated disassembly and assembly, this invention provides a telescopic platform for self-climbing tower cranes. The following detailed description, in conjunction with the accompanying drawings, provides further insights into this telescopic platform for self-climbing tower cranes.

[0018] Referring to Figures 1-5, a telescopic platform for a self-climbing tower crane is connected to the end of a support frame 1 near the building structure, providing a foothold for workers to perform construction on two main supports 2. The telescopic platform includes: a hanging plate 6, fixedly connected to the end of the support frame 1 near the building structure; a first platform 3, fixedly connected to the lower end of the hanging plate 6 and located below the two main supports 2, extending in the direction toward the building structure; a telescopically adjustable connector 7, one end connected to the first platform 3 and the other end facing the building structure; and a second platform 4, fixedly connected to the other end of the connector 7, and the extension or retraction of the connector 7 can control the second platform 4 to move away from or closer to the first platform 3. Both the first platform 3 and the second platform 4 are horizontally arranged for workers to stand on.

[0019] By setting up a first platform 3 and a second platform 4 for workers to stand on, it is convenient for workers to move back and forth to carry out construction on the main support 2. Furthermore, by setting up a telescopic and adjustable connector 7, the second platform 4 can be moved away from or closer to the first platform 3, thereby adjusting the usable area of ​​the entire platform and expanding the construction range. It can be flexibly adjusted according to the working conditions, and the entire platform can also be used as a passageway.

[0020] Referring to Figures 4-5, the connector 7 includes a sleeve 701 and a connecting rod 702. The sleeve 701 is fixed to one of the first platform 3 and the second platform 4. One end of the connecting rod 702 is slidably inserted into the sleeve 701, and the other end is fixedly connected to the other of the first platform 3 and the second platform 4. The connector 7 also includes a locking member for fixing the sleeve 701 and the connecting rod 702.

[0021] Furthermore, the locking component includes a fixing bolt, a through hole, and multiple screw holes. The through hole is opened on the sleeve 701 and communicates with the inside of the sleeve 701. The multiple screw holes are all opened on the connecting rod 702 and are spaced apart along the length of the connecting rod 702. The connecting component 7 can be adjusted by passing the fixing bolt through the through hole and selectively inserting it into the multiple screw holes.

[0022] By adopting the above design, it is convenient to adjust the distance between the second platform 4 and the first platform 3, thereby expanding or shrinking the usable area of ​​the entire platform. It can be flexibly adjusted. When the distance between the second platform 4 and the first platform 3 reaches the maximum adjustable distance, the gap between the second platform 4 and the first platform 3 is still smaller than the width of the worker's foot, preventing the worker from stepping into a hole.

[0023] As shown in Figures 4-5, there are multiple connectors 7, and the multiple connectors 7 are arranged at intervals along the width direction of the first platform 3.

[0024] By adopting the above design and setting multiple connectors 7, the stability of the second platform 4 can be greatly improved, and its load-bearing performance can be enhanced.

[0025] The second platform 4 is connected to a third platform 5 at both ends of its width direction. The third platform 5 has at least a first flip position and a second flip position compared to the second platform 4. When the third platform 5 flips to the first flip position, it extends to the outside of the main support 2. When the third platform 5 flips to the second flip position, it retracts to the inside of the main support 2.

[0026] When the third platform 5 is flipped to the first flipping position, it is in a horizontal state; when the third platform 5 is flipped to the second flipping position, it is in a vertical state.

[0027] By adopting the above design, the third platform 5 can be flipped to the outside of the main support 2, which can serve as a foothold for workers. This facilitates workers to carry out relevant construction operations on the outside of the main support 2. When not in use, the third platform 5 can be flipped to the inside of the main support 2 to achieve folding, thus avoiding interference with other components of the tower crane and affecting the climbing operation of the support frame 1.

[0028] The hanging plate 6 is connected and fixed to the support frame 1 by bolts.

[0029] By adopting the above design, the entire platform can be easily disassembled and reassembled, and can be reused.
