Tower crane attachment deviceTechnical Field
The invention relates to the technical field of tower cranes, in particular to a tower crane attachment device.
Background
The tower crane is required to be arranged on a building to keep stable after exceeding a certain height, and an object with a supporting function is attached. One end of the attachment is fixed on a standard section of the tower crane, and the other end of the attachment is fixed on a girder of a building. The two ends must be arranged on the same level, otherwise the connecting pin shaft cannot be inserted into the pin hole, and great installation and disassembly are difficult. The reason why the two ends cannot be arranged on the same horizontal plane is as follows: firstly, the manual installation of an operator can not well ensure that two ends are positioned on the same plane, and secondly, the standard joints are connected through connecting sleeves, and the climbing claws are arranged on the surfaces of the standard joints, so that the positions needing to be avoided are attached. Therefore, many existing solutions adopt electric welding to connect parts in the attachment device, but the strength of the electric welding is not as good as that of the pin shaft connection, so that once welding is problematic, a series of serious safety accidents such as attachment fracture, tower crane overturning and the like can occur.
In addition, in the existing tower crane adhesion, the frame and the standard section of the tower crane are in direct contact, the stress surface of the tower crane is extremely small, the impact force of the stress surface is extremely large, the friction force is also extremely large, the impact force and the shearing force born by four upright posts of the standard section are also uneven, and the adhesion device cannot play the roles of stabilizing the tower crane and buffering and releasing the acting force. Therefore, the standard section of the tower crane is easy to deform, bend and break, so that serious safety accidents caused by overturning the tower crane occur.
Secondly, the frame of current tower crane attachment device is fixed knot structure, only can be applicable to the standard festival of corresponding specification, and the commonality is not strong, needs two people to cooperate when installing the frame simultaneously and carries out the operation, and is inefficiency.
In view of the foregoing, there is a need for a tower crane attachment apparatus that solves the problems of the prior art.
