Description

Technical Field

[0001] The utility model relates to the technical field of attachment ear seats, in particular to an attachment ear seat for a tower crane used for a concrete frame surrounding beam. Background Art

[0002] Tower crane, short for tower crane, is a kind of lifting equipment used in construction. During the construction process, as the building continues to grow taller, the tower crane also needs to use its own climbing device to continue to climb and increase height. When the tower crane is raised to a height exceeding the independent height, in order to continue the jacking and to ensure the overall stability of the tower crane, the tower crane must be connected to the building using an attachment structure composed of an attachment frame, a connecting pin shaft, a tie rod, etc., so that the tower crane is attached to the building.

[0003] After the existing tower crane attachment ear seat is installed on the concrete frame embracing beam, the orientation angle of the attachment ear seat is fixed. During the actual building overlap process, when the pull rod cannot be docked with the attachment ear seat due to angle problems, it is inconvenient for the staff to adjust the orientation angle of the attachment ear seat, which reduces the applicability of the attachment ear seat. Therefore, we propose a tower crane attachment ear seat for a concrete frame embracing beam to solve the above problem. Utility Model Content

The first fastener mechanism comprises a first fixing bolt 4 and a first nut 5. One end of the first fixing bolt 4 passes through the first embracing beam half frame 1 and the second embracing beam half frame 2 and is threadedly installed with the first nut 5. The first embracing beam half frame 1 and the second embracing beam half frame 2 are sleeved and fixedly installed on the concrete wall 3 through the plurality of first fastener mechanisms. A rotation groove 6 is provided on one side of the first embracing beam half frame 1. A swivel 7 is rotatably installed in the swivel groove 6, and an attached ear plate body 8 is fixedly installed on one side of the swivel 7. A plurality of circular holes 10 are respectively opened on the first embracing beam half frame 1, and a plurality of side plates 11 are respectively fixedly installed on the swivel 7. A plurality of side plates 11 are each provided with a plate hole 12. A second fastener mechanism for the plate hole 12 and the corresponding circular hole 10 is provided on the corresponding side plate 11. The second fastener mechanism includes a second fastening bolt 13 and a second nut 14. One end of the second fastening bolt 13 passes through the corresponding plate hole 12 and the outside of the circular hole 10 and is threadedly installed with the second nut 14. Through multiple sets of second fastener mechanisms, the position of the attached ear plate body 8 after the angle adjustment is fixed to prevent the attached ear plate body 8 from rotating.

[0019] Furthermore, the cross section of the rotating groove 6 is arranged in an L-shaped structure, and the rotating ring 7 is adapted to the rotating groove 6, so that the rotating ring 7 can rotate in the rotating groove 6 to adjust the orientation angle of the attached ear plate body 8.
