Auxiliary supporting mechanism of portable overhaul ladder for hydraulic engineering

OUYANG YUZHEN

The invention discloses an auxiliary supporting mechanism of a portable overhaul ladder for hydraulic engineering. The auxiliary supporting mechanism comprises a ladder body and anti-skid blocks. According to the auxiliary supporting mechanism, sliding connection mechanisms are arranged on the tops of auxiliary supporting rods, fixed blocks are put into slide blocks through connecting rods by rotating rotary knobs, then the slide blocks slide to drive the auxiliary supporting rods to be unfolded to achieve supporting or to draw close, then the rotary knobs are released, and first springs provide elastic forces to eject the fixed blocks, so that reverse latches lock front latches to fix the positions of the slide blocks, and therefore, the effect of fixing the positions of the auxiliary supporting rods is achieved conveniently. By arranging auxiliary fixing devices at the bottoms of the auxiliary supporting rods, shells are rotated to drive connecting parts to rotate along grooves, andthen anti-skid pads are attached to the ground. By rotating a ladder body, the auxiliary supporting rods are driven to swing to adjust the inclined planes, so that the connecting parts rotate along the shells. In the adjusting process, the anti-skid pads are attached to the ground all the time, so that the effect of enlarging the contact area with the ground to improve the safety is achieved.

本发明公开了一种水利工程便携式检修用扶梯的辅助支撑机构，包括扶梯本体和防滑块，本发明通过在辅助支撑杆的顶部设置了滑动连接机构，通过旋转旋钮，使转动件通过连接杆将固定块收入滑块内，然后滑动滑块带动辅助支撑杆展开进行支撑或者进行靠拢，再松开旋钮，由第一弹簧提供弹力，将固定块顶出，使逆卡齿卡住正卡齿，固定滑块位置，达到方便进行固定辅助支撑杆位置的效果，通过在辅助支撑杆底部设置了辅助固定装置，通过旋转壳体，带动连接件沿着凹槽旋转，然后将防滑垫贴合地面，通过转动扶梯本体，带动辅助支撑杆摆动调节倾斜面，使连接件沿着壳体旋转，调节的过程中防滑垫始终贴合地面，达到加大与地面的接触面积，提高安全性的效果。
