The tower body is a frame composed of a plurality of cross-braced members, including: a platform, a first fixed beam, a second fixed beam, and an oblique lock. The first fixed beam is fixedly arranged at the bottom of the front end of the platform through a pin shaft and is fixed to the tower body through a beam buckle; the second fixed beam is connected to the platform through two oblique locks and is fixed to the tower body through a beam buckle, one end of the two oblique locks is arranged on the second fixed beam, and the other end is connected to the side of the bottom end of the platform; wherein the platform is fixed to the tower body through the first fixed beam and the second fixed beam.

[0005] Furthermore, long bolts are arranged on both sides of the bottom end of the platform, and the long bolts are connected to the first fixed beam through an oblique lock.

[0006] Furthermore, two ear plates are arranged on the first fixed cross beam, and the two ear plates are fixedly spaced substantially apart from the ear plate on the right side of the platform and are fixedly connected via a pin shaft.

[0007] Furthermore, two diagonal locks are fixed at the center position of the second fixed beam by bolts.

[0008] Furthermore, both ends of the first fixed cross beam and the second fixed cross beam are designed with end surfaces parallel to the diagonal web bars and are fixedly connected to the diagonal web bars through cross beam buckles.

[0009] Furthermore, the diagonal lock is hung on the second fixed beam through a hook.

[0010] The utility model discloses a detachable large flat-top tower crane platform, which is installed on a tower body. The tower body is a frame formed by a plurality of cross-braced diagonal beams, including a platform, a first fixed beam, a second fixed beam, and an inclined lock. The first fixed beam is fixedly arranged at the bottom of the front end of the platform by a pin shaft and is fixed to the tower body by a beam buckle. The second fixed beam is connected to the platform by two inclined locks and is fixed to the tower body by a beam buckle. One end of the two inclined locks is arranged on the second fixed beam, and the other end is connected to the side surface of the bottom end of the platform. The platform is fixed to the tower body by the first fixed beam and the second fixed beam, which solves the problems in the prior art that the flat-top crane platform causes an excessive burden on the main body of the large flat-top tower crane and the platform crane platform is inconvenient to transport.

[0011] The beneficial effects of the utility model are:

[0012] The new connection method of the detachable large flat-top tower crane platform optimizes the platform installation, processing and transportation methods, and further reduces the manufacturing and transportation costs of the platform. BRIEF DESCRIPTION OF THE DRAWINGS
