Abstract
The utility model relates to a rapidly mounted tower crane revolving platform device which is arranged at the side part of a platform connecting structural piece in a leaning manner and comprises a platform connector structure and a platform frame, wherein the platform connector structure is fixed on one side of the platform frame; the platform connector structure is linked with the platform connecting structural piece in a hinge pin structure mode; the side wall of the revolving platform device leans against the side wall of the platform connecting structural piece. Based on the self weight of the revolving platform and the support counterforce provided at the contact part of the side walls of the revolving platform and the platform connecting structural piece, the stability of the revolving platform is improved, the height of the revolving platform relative to the platform structural piece is also reduced, the mounting is convenient and rapid, and moreover, the manufacturing cost is effectively lowered.
Description
Technical field
The utility model belongs to the field engineering field of tower crane rotation platform, particularly a kind of tower crane Fast Installation turn table device.
Background technology
Along with economic fast development, the construction period is more and more urgent to the equipment installation requirement of marching into the arena.Not only to guarantee the safety of operation for the installation of tower crane all parts, also require efficient work.As shown in Figure 1, the version that traditional turn table great majority adopt cantilever beam 1 to add strut 2 is fixed on platform connection member 3.The two ends of strut 2 connect with cantilever beam 1 and platform connection member 3 respectively by bearing pin 4, and strut 2 is mainly used in improving the loading strength of cantilever beam 1.This kind of frame mode not only increased the manufacturing cost of enterprise, and setting accuracy is difficult to assurance, the poor stability of platform.On the other hand, installation difficulty is large, not easy.
Utility model content
Technical problem to be solved in the utility model is, a kind of tower crane Fast Installation turn table device is provided, and reasonably reduces enterprise's manufacturing cost, effectively shortens the set-up time, increases work efficiency.
The utility model is to realize like this, a kind of tower crane Fast Installation turn table device is provided, it is mounted on the sidepiece of platform connection member, turn table device comprises platform joint design and platform framework, platform joint design is fixed on platform framework one side, platform joint design connects with platform connection member by pin shaft structure mode, and the sidewall of turn table device abuts on the sidewall of platform connection member.
Further, turn table device connects with platform connection member by two pin shaft structure modes.
Further, pin shaft structure comprises stay bearing plate, the platform joint design being fixed on platform connection member sidewall and connects bearing pin, is respectively equipped with and the pin-and-hole that is connected bearing pin cooperation on stay bearing plate and platform joint design.
Further, each pin shaft structure comprises two stay bearing plates, and platform joint design is arranged between two stay bearing plates.
Further, the pin-and-hole position of platform joint design is higher than platform framework upper surface.
Further, platform joint design is square column.
Compared with prior art, tower crane Fast Installation turn table device of the present utility model connects with platform connection member by pin shaft structure mode, and the sidewall of turn table device abuts on the sidewall of platform connection member.The deadweight of turn table and the reaction of bearing providing with platform connection member sidewall contact place are provided, improve the stability of turn table, also reduce the height of turn table with respect to platform structure part simultaneously.And be convenient to manufacture, install fast, effectively reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is traditional turn table scheme of installation;
Fig. 2 is the schematic perspective view of the utility model one preferred embodiment;
Fig. 3 is the schematic diagram of the utility model one preferred embodiment real use state;
Fig. 4 is the side-looking plan sketch of Fig. 3.
The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to shown in Fig. 2 to Fig. 4 preferred embodiment and the actual installation schematic diagram of the utility model tower crane Fast Installation turn table device.Turn table device 5 is mounted on the sidepiece of platform connection member 6.Turn table device 5 comprises platform joint design 8 and platform framework 7, and platform joint design 8 is fixed on platform framework 7 one sides by welding manner.
Platform joint design 8 connects with platform connection member 6 by pin shaft structure mode, and the sidewall of turn table device 5 abuts on the sidewall of platform connection member 6.In the present embodiment, turn table device 5 connects with platform connection member 6 by two pin shaft structure modes.
Pin shaft structure comprises the stay bearing plate 9 that is fixed on platform connection member 6 sidewalls, platform joint design 8 and connects bearing pin 10, is respectively equipped with and the pin-and-hole 11 that is connected bearing pin 10 and coordinates on stay bearing plate 9 and platform joint design 8.In the present embodiment, each pin shaft structure comprises two stay bearing plates 9, and platform joint design 8 is arranged between two stay bearing plates 9.Pin-and-hole 11 positions of platform joint design 8 are higher than the upper surface of platform framework 7.Platform joint design 8 is square column.
Turn table device 5 of the present utility model is to connect by bearing pin connection mode with platform connection member 6, lightweight, easy for installation, is beneficial to assembling and manufactures.Be turn table device 5 Gravitative Loads due to what rely on, the lower end of turn table erecting device 5 and platform connection member 6 sidewalls are close together, forming surface contact, distribution of force is even, and stability improves.Meanwhile, the utility model can reduce the height of turn table effectively, improves the stability of turn table.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
