Sectional type arm support
The invention belongs to the field of elevating arm supports of engineering machinery, and discloses a sectional arm support which comprises a first box-type arm section, a second box-type arm section, a first connector, a second connector and a reinforcing locking structure, and the first box-type arm section and the second box-type arm section are adjacently arranged in the length direction of the arm support; the first connector comprises a first plate body fixed to an end opening of the first box type arm section, a first plate hole formed in the first plate body in a penetrating mode and a sleeve which is aligned to the first plate hole and extends perpendicular to the plate face of the first plate body. The second connector comprises a second plate body fixed to an end opening of the second box type arm section and a plug pin which is perpendicular to the plate face of the second plate body in an extending mode, the plug pin penetrates through the first plate hole and is detachably inserted and fixed into the sleeve, and the first plate body and the second plate body form plate face butt joint; and the reinforced locking structure is used for locking the bolt and the sleeve. The sectional type arm support is excellent in stress performance, high in connection reliability between the arm sections and low in damage risk and disassembly and assembly difficulty.
本发明属于工程机械举高类臂架领域，公开了一种分段式臂架，包括：第一箱型臂节、第二箱型臂节、第一接头、第二接头以及加强锁定结构，其中，第一箱型臂节和第二箱型臂节沿臂架长度方向相邻设置；第一接头包括固定在第一箱型臂节的端部开口的第一板体、在第一板体上贯穿形成的第一板孔以及与第一板孔对位且垂直于第一板体的板面延伸设置的套筒；第二接头包括固定在第二箱型臂节的端部开口的第二板体以及垂直于第二板体的板面延伸设置的插销，插销穿过第一板孔且可拆卸地插接固定在套筒内，第一板体与第二板体形成板面对接；以及加强锁定结构，用于锁定插销和套筒。本发明的分段式臂架受力性能优异，臂节间连接可靠性高，损坏风险和拆装难度低。
