Special telescopic ladder for inspection well
The invention relates to a ladder, in particular to a special telescopic ladder for an inspection well. Two concave corners (6) arranged at intervals are arranged on one side of an inner opening of awellhead ring (23), a protruding ring (5) is arranged on the outer edge of an upper opening of the wellhead ring, rotating shafts (9) at two ends of H-shaped sections (12) at the upper end of the telescopic ladder are inserted into rotating shaft holes (4) which are formed opposite to the two concave corners respectively, and a safety net (2) is fastened on the upper end surface of the wellhead ring; and the telescopic ladder comprises a plurality of H-shaped sections arranged at intervals from top to bottom, concave grooves, close to the lower portions of middle plates (10) at the two ends, of every two adjacent H-shaped sections are connected with the upper ends of upper connecting rods (14) respectively, the lower ends of the upper connecting rods are connected with the upper ends of lower connecting rods (16), and the lower ends of the lower connecting rods are connected into the concave grooves in the upper portions of the middle plates of the lower adjacent H-shaped sections. Fixing points of the telescopic ladder are formed through the concave corners of the wellhead rings, so that the telescopic ladder can conveniently enter the well for operation, and the safety net can protect a worker from being injured by foreign matters during operation.
一种窨井专用伸缩梯子，涉及一种梯子，在井口环（23）的内口一侧设有两间隔设置的凹陷角（6），井口环的上口外缘设有凸出环（5），伸缩梯子上端的“H”字型材（12）两端的旋转轴（9）分别插接两凹陷角相对面设置的旋转轴孔（4）中，安全网（2）扣在井口环的上端面上；伸缩梯子包括多根由上至下间隔设置的“H”字型材，两两相邻的“H”字型材靠近两端中部板（10）下部的凹陷槽分别与上连接杆（14）上端连接，上连接杆下端与下连接杆（16）上端连接，下连接杆下端连接在下部相邻“H”字型材中部板上部的凹陷槽中；本发明通过井口环的凹陷角形成伸缩梯子的固定点方便进入井内作业，安全网可保护作业时不被异物砸伤。
