Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a tower crane wall-attached cross-type inner support rod structure. Background Art

[0002] Tower cranes have a certain independent height. When the construction environment requires the tower crane to exceed its calibrated independent height, it needs to be attached to the wall to continue climbing within the allowable range to meet the construction requirements. At the same time, as the design of tower cranes becomes more conservative and users have higher and higher requirements for tower crane performance, manufacturers generally design a set of standard internal support systems for wall-mounted frames to improve the force safety of the nodes and the overall stability of the tower crane. There are currently two main types of internal support structures for wall-mounted frames on the market:

[0003] The first type is that two independent support beams are cross-shaped and supported on the inner side of the standard angle steel of the tower body. They are arranged on the upper and lower sides of the wall frame. Adjusting bolts are used to tighten the tower body, and clamps are provided to clamp the tower body to prevent it from falling. Since the clamping device is connected by bolts, the actual bolt assembly process is more complicated, and the working conditions of the tower crane are more complicated during operation. Therefore, there are a series of safety hazards caused by the loosening of bolts and nuts of the tower body under certain working conditions.

[0004] The second type is that the four support claws are fixed to the wall frame with pins. After the tower body is tightened by adjusting screws, the force can be transmitted to the wall frame. The support claws are large in size and the overall weight of the structure can reach 400 kilograms, which makes installation and disassembly difficult. Summary of the invention
