The invention discloses a steel truss connecting rod length adjusting device. The device comprises a first connecting rod and a second connecting rod. An installation box is welded to the outer side of the first connecting rod. The front wall of the installation box is rotationally provided with a first rotating shaft. A first gear is connected to the first rotating shaft. A second gear is engagedwith the first gear. A second gear key is connected to a second rotating shaft. A first bevel gear is connected to a second rotating shaft key. A second bevel gear is engaged with the first bevel gear. A second bevel gear key is connected to a third rotating shaft. The third rotating shaft is rotationally connected with a first installation block through a bearing. The first installation block isfixed at the upper end of the first connecting rod. A screw rod is welded to the upper end of the third rotating shaft. A driving nut is arranged on the screw rod in a threaded drive mode. A second installation block is embedded in the outer side of the driving nut. A second installation block is fixed to the lower end of the second connecting rod. A locking mechanism is arranged between the installation box and the second gear. The length of truss connecting rods can be adjusted, and the connecting rod tension stability and firmness are improved.
本发明公开了一种钢构网架连接用杆件长度调节装置，包括第一连接杆和第二连接杆，第一连接杆外侧焊接有安装箱，安装箱的前壁转动有第一转轴，第一转轴上连接有第一齿轮，第一齿轮啮合有第二齿轮，第二齿轮键连接在第二转轴上，第二转轴键连接有第一锥齿轮，第一锥齿轮啮合有第二锥齿轮，第二锥齿轮键连接在第三转轴上，第三转轴通过轴承转动连接有第一安装块，第一安装块固定在第一连接杆的上端，第三转轴的上端焊接有丝杆，丝杆上螺纹传动有传动螺母，传动螺母的外侧镶嵌有第二安装块，第二安装块固定在第二连接杆的下端，安装箱与第二齿轮之间设有锁止机构。实现对网架连接杆的长度调节，提高连接杆拉紧的稳定性和牢固性。
