Description

Technical Field

[0001] The utility model relates to a tower crane flippable platform which adopts a connecting beam and belongs to the technical field of tower crane platform design. Background Art

[0002] Tower crane (hereinafter referred to as "tower crane") is a kind of lifting equipment commonly used in the construction industry. Due to the high operating height of tower crane, operators are required to go up and down and work during use. At the same time, personnel are also required to perform daily maintenance on various parts. Therefore, it is necessary to build a platform for operators to stay and work.

[0003] The existing platform structure located outside the tower crane housing mostly relies on the main chord or main structure of the main structure of the tower crane housing. When designing the platform for a long span of the main structure, the platform structure is generally thickened to improve the strength of the platform structure to meet the needs. This structure increases the amount of material used. Figure 1-Figure 3 The platform structure, Figure 1 The middle platform mounting seat 2 is welded on the main chord 1 of the main structure, the cantilever beam 4 is welded on the platform 3, the cantilever beam 4 penetrates into the platform mounting seat 2, and the connecting piece 5 fixes the platform 3 and the main structure of the part through the connecting holes arranged on the platform mounting seat 2 and the cantilever beam 4. When the platform span is large, channel steel needs to be added at the bottom of the platform to improve the stress condition of the platform. Figure 2 The middle platform mounting seat 2 is welded on the main chord 1 of the main structure, the cantilever beam 4 is welded on the platform 3, the cantilever beam front baffle 6 and the cantilever beam rear baffle 7 are welded on the cantilever beam 4, the cantilever beam 4 passes through the platform mounting seat 2, and the cantilever beam front baffle 6 and the cantilever beam rear baffle 7 limit the front and rear displacement of the cantilever beam 4 through the platform mounting seat 2. The connecting piece 5 is arranged on the platform mounting seat 2 and connected with the cantilever beam rear baffle 7 to fix the platform 3 to the main structure of the part. When the platform span is large, channel steel needs to be added at the bottom of the platform to improve the stress condition of the platform. Figure 3 The middle platform mounting seat 2 is welded to the main chord 1 of the main structure, the cantilever beam 4 is welded to the platform 3, the pad 8 is welded to the cantilever beam 4, the cantilever beam 4 passes through the platform mounting seat 2, the pad 8 presses on the platform mounting seat 2 to limit the rotation of the cantilever beam 4, and the connecting piece 5 is arranged on the platform mounting seat 2 and connected to the cantilever beam 4 to fix the platform 3 to the main structure of the part sleeve.

[0004] At the same time, for platforms that need to work in areas below the height of the main structure, a hanging basket is usually used. This structure cannot be assembled on the ground when the parts are assembled. It is usually assembled at high altitude, which increases the difficulty of tower crane assembly and makes the tower crane installation process cumbersome. Figure 4The hanging basket structure is suspended to the lower side of the main structure, and the hanging basket mounting seat 10 is welded on the main structure 9. After the main structure 9 is hoisted to high altitude for assembly, the hanging basket 11 is installed on the hanging basket mounting seat 10, and the connecting piece 5 is used to connect the hanging basket 11 through the connecting hole arranged on the hanging basket mounting seat 10, so as to fix the hanging basket 11 to the main structure of the part. Since the bottom surface of the hanging basket 11 is lower than the bottom surface of the main structure, the hanging basket cannot be installed on the ground.

[0005] Therefore, it is necessary to design a new tower crane platform, which does not need to thicken the platform structural parts with long main structure spans. At the same time, the structure of the hanging basket can also realize the assembly of the platform on the ground without having to be completed in the air. Utility Model Content

[0013] As a preferred solution of the utility model, one end of the cantilever beam is connected to the other end of the connecting beam by means of a latch, a pin or welding.

[0014] As a preferred solution of the utility model, a pad corresponding to the connecting beam is welded below the main structure of the tower crane section, and the connecting beam is pressed on the pad to ensure that the tower crane flip platform does not deflect under pressure.

[0015] As a preferred solution of the utility model, when the tower crane flip platform is in use, the connecting beam is perpendicular to the ground; when the tower crane flip platform is assembled, the connecting beam is flipped so that the connecting beam is inclined to the ground.

The connecting beam designed in the utility model can rotate around the connecting ear plate, so that the platform suspended under the main structure can be flipped to above the lower surface of the main structure, so that the platform can be installed on the ground, improving the assembly efficiency of the tower crane.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0028] like Figure 5 As shown, the utility model proposes a tower crane reversible platform using a connecting beam, involving: a main structure 9, an ear plate 13, a connecting beam 12, a tower crane operator work platform 17, a cantilever beam 4, a latch 15, a pin shaft 14 and a cushion block 16. The installation process of this platform installation method is as follows:

[0029] The ear plate 13 and the pad 16 are welded to the main structure 9, the cantilever beam 4 is welded to the lower surface of the tower crane operator's work platform 17, the cantilever beam 4 passes through one end of the connecting beam 12, the connecting beam 12 is connected to the cantilever beam 4 by a latch 15, and the other end of the connecting beam 12 is connected to the ear plate 13 by a pin 14. The connecting beam 12 is pressed on the pad 16 to ensure that the tower crane operator's work platform 17 does not deflect under pressure. The connecting beam 12 and the cantilever beam 4 form an L-shaped beam structure. In the utility model, the connecting beam 12 and the cantilever beam 4 are connected by a latch 15. The L-shaped beam structure formed by the connecting beam 12 and the cantilever beam 4 can also be formed by pin connection, welding, etc. This structure makes it easy to complete the segmentation of the platform in the case of a long span. When this structure is suspended, it is in a state such as Figure 6 At the same time, this structure can be turned over to the state shown in the figure when installed on the ground.

The main structure 9 at the position where the platform needs to be segmented only needs to weld the corresponding connecting ear plate 13, so as to realize the segmentation of the platform, improve the stress condition, and reduce material loss. The connecting beam 12 can rotate around the connecting ear plate 13, so that the platform suspended under the main structure can be flipped and higher than the lower bottom surface of the main structure, so that the platform can be installed on the ground to improve the assembly efficiency of the tower crane.
