The invention belongs to the technical field of crane booms, and particularly relates to a high-strength steel welded pipe for a crane boom, which comprises a boom seat, a fixed groove is formed in one side of the top of the boom seat, a high-strength steel support arm is fixedly mounted on the inner wall of the fixed groove, and a movable groove is formed in the outer wall of the bottom of the high-strength steel support arm. Sliding grooves are formed in the inner walls of the opposite sides of the movable grooves correspondingly, sliding strips are slidably connected to the inner walls of the two sliding grooves correspondingly, and the opposite sides of the two sliding strips are fixedly connected with the same high-strength steel extension arm. According to the invention, through the arrangement of a stable supporting rod, a high-strength steel main welding pipe, a high-strength steel extension welding pipe and a mounting plate, the connection between a high-strength steel supporting arm and a high-strength steel extension arm can be further stabilized, and through the cooperation of two supporting plates, a top plate, a fixing screw rod and a fixing hole, the firmness of the high-strength steel main welding pipe can be enhanced; therefore, the connection between the high-strength steel support arm and the high-strength steel extension arm can achieve a firmer effect.

    本发明属于起重机臂架技术领域,尤其是起重机臂架用高强钢焊管,包括臂座,所述臂座顶部一侧开设有固定槽,所述固定槽内壁固定安装有高强钢支撑臂,所述高强钢支撑臂底部外壁开设有活动槽,所述活动槽相对一侧内壁均开设有滑动槽,两个所述滑动槽内壁均滑动连接有滑动条,两个所述滑动条相对一侧固定连接有同一个高强钢延伸臂。本发明通过设置的稳固支杆、高强钢主焊管、高强钢延伸焊管和安装板,可以对高强钢支撑臂和高强钢延伸臂之间的连接起到进一步稳固的作用,再配合设置的两个支撑板、顶板、固定螺杆和固定孔,可以加强高强钢主焊管的牢固性,因此高强钢支撑臂和高强钢延伸臂之间的连接可以达到更加牢固的效果。
