The invention relates to the technical field of chord member joints, and provides a novel tower crane tower body chord member joint which comprises a bottom plate, a connecting rod is fixedly connected to the outer surface of the bottom plate, a fixed U-shaped block is fixedly connected to one end of the connecting rod, a first chord member is fixedly connected to the outer surface of the fixed U-shaped block, and a second chord member is fixedly connected to the outer surface of the first chord member. A second chord member is movably embedded in the first chord member, a plurality of square grooves are formed in the outer surface of the second chord member, a second L-shaped fixing rod is fixedly connected to the outer surface of the first chord member, and a second threaded rod is movably embedded in the second L-shaped fixing rod. A second threaded rod is rotated to drive a small square block to move towards one side under the limitation of a third limiting telescopic rod, when the small square block slides into a square groove, the second chord member can be limited, the length between the first chord member and the second chord member is increased at the moment, and the device can be suitable for being used in different scenes.
本发明涉及弦杆接头技术领域,提供了一种新型塔式起重机塔身弦杆接头,包括:底板,所述底板的外表面固定连接有连接杆,所述连接杆的一端固定连接有固定U型块,所述固定U型块的外表面固定连接有弦杆一,所述弦杆一的内部活动嵌设有弦杆二,所述弦杆二的外表面开设有多个方槽,所述弦杆一的外表面固定连接有L型固定杆二,所述L型固定杆二的内部活动嵌设有第二螺纹杆,本发明实施例中,拉动弦杆二在弦杆一的内部滑动,转动第二螺纹杆从而带动小方块在限位伸缩杆三的限位向一侧移动,当小方块滑动至方槽的内部时,可对弦杆二进行限位,此时弦杆一与弦杆二之间的长度变长,可适应不同场景的使用。
