In some embodiments, as shown in fig. 2 and 3, the platform assembly 200 may include: a pair of main beams 210, a pair of side beams 220, and a pair of support beams 230.

Wherein a pair of girders 210 are disposed parallel to each other and one of the girders 210 is used to connect the columns 110 of the quay crane 100.

The pair of side beams 220 are disposed parallel to each other and are respectively connected to the corresponding two ends of the pair of main beams 210, so that a platform frame is formed by the pair of side beams 220 and the pair of main beams 210.

A pair of support beams 230 are attached inside the platform frame.

Specifically, the platform assembly 200 is provided with a pair of parallel main beams 210 and a pair of parallel side beams 220, wherein the pair of parallel side beams 220 are connected between two ends of the pair of main beams 210 to form a rectangular platform frame, the inside of the platform frame is connected with a pair of support beams 230, and the pair of support beams 230 are used for supporting the cargo compartment cover 500, so that the structure is light and easy to replace and maintain.

In some embodiments, the support beams 230 may have various connection forms within the platform frame, for example, a pair of support beams 230 may be connected in parallel between a pair of main beams 210 or side beams 220, and a pair of support beams 230 may be disposed along the diagonal of the platform frame, respectively.

In some embodiments, as shown in fig. 3, a backing plate 240 is provided on the support beam 230, and the backing plate 240 is a rubber member.

That is, a pad of rubber is laid on the support beam 230 to protect the surface of the support beam 230 while preventing the cargo compartment ceiling 500 placed on the support beam 230 from being worn out in contact with the support beam 230.

In some embodiments, as shown in fig. 4, 5 and 6, a plurality of connection holes 241 are formed in the pad 240, and the pad 240 is connected to the support beam 230 by inserting fasteners 242 through the connection holes 241.

Specifically, a plurality of connection holes 241 are uniformly formed on the surface of the pad 240, and the pad 240 is detachably connected with the support beam 230 by penetrating fasteners 242 in the connection holes 241, thereby realizing replacement and maintenance after the pad 240 is worn.

In some embodiments, as shown in fig. 5 and 6, the connection hole 241 is formed as a countersink.

That is, the connection holes 241 of the pad 240 are designed in the form of countersunk holes to facilitate the installation of the fasteners 242 (which may be bolts, for example).

In some embodiments, as shown in fig. 3, 7, 8, and 9, the platform assembly 200 may further include: a pair of anti-shear supports 250.

Wherein one girder 210 is connected to a pair of shear supports 250 to connect the columns 110 of the quay crane 100 through the pair of shear supports 250.

Specifically, the shear mount 250 may include a mount body 251, a top plate 252, a spacer 253, a pair of support plates 254, and a shear plate 255. The support body 251 is used for connecting the upright post 110 of the quay crane 100, the top plate 252 is connected to one side of the support body 251, a gasket 253 is arranged between the top plate 252 and the support body 251, a shear plate 255 is connected to the plane of the vertical top plate 252, the support plates 254 are vertically connected to the surface of the top plate 252, a pair of support plates 254 are respectively fixed to two sides of the shear plate 255, the shear plate 255 is connected to the main beams 210 close to the upright post 110 of the quay crane 100, and therefore, one main beam of the platform assembly 200 is respectively connected with the upright post 110 of the quay crane 100 through the shear supports 250 on two sides, and the platform assembly can be effectively prevented from being deflected by shear force.

Shear supports 250 may be provided on both sides of the connection 400 of the platform assembly 200 to the column 110 of the quay crane 100 to further enhance the reliability of the installation of the platform assembly 200.

One end of the support bar is connected to the lower edge of one side rail 220 (i.e., away from the main rail 220 for connecting the columns 110) of the platform assembly 200.

The other end of the support bar is connected to a connection socket to connect the column 110 of the quay crane 100 through the connection socket.

That is, one end of the support bar through the fixing assembly 300 is connected to the column 110 of the quay crane 100 through the connection base, and the other end is connected to the lower edge of the side beam 220, which is far away from the connection column 110, thereby forming a stable delta support, having a simple structure and being firmly supported. In addition, since the fixing assembly 300 is positioned below the platform assembly 200, there is no interference with the movement of the deck lid placed above the platform assembly 200, and the use is more convenient.

Further, it can also be designed to: the middle part of the supporting rod is provided with a foldable structure, and the lower end of the supporting rod is rotatably connected with the connecting seat. At the same time, the main beam is allowed to rotate along the connection 400. Thus, without the need to place a cargo hold cover over the platform assembly 200, the middle portion of the support bar can be folded, and the platform can rotate under gravity toward the column when it loses support and ultimately rest against the column. The design provides a freely changeable operating and use space for the crane.

A quay crane 100 according to an embodiment of the second aspect of the invention, as shown in fig. 1, comprises: a plurality of posts 110 and a platform.
