Application of telescopic ladder for inspection well operation
The invention provides application of a telescopic ladder for inspection well operation, and relates to an inspection well ladder. The telescopic ladder comprises a U-shaped sliding body formed by a plurality of layers of double-inward-bent groove rods (10) and a pedal (8), wherein the pedal is arranged between two lower extending plates (15) arranged at the lower ends of the two double-inward-bent groove rods; screw rods A (17) of two sets of screws penetrate through the outer sides of two unthreaded holes (20) of the lower extending plates and then are connected with two screw holes (57) ofthe pedal; protruding blocks (9) are arranged on the inner sides of the upper ends of the two double-inward-bent groove rods correspondingly; inner protruding strips (12) are arranged on the inner sides of openings of grooves (11) correspondingly to form the U-shaped sliding body; a plurality of layers of U-shaped sliding body are formed by connecting the two double-inward-bent groove rods; and the upper ends of the two double-inward-bent groove rods on the uppermost portion are fixedly connected with the middle of a supporting pipe (2). According to the application, the plurality of layers ofU-shaped sliding body are formed by connecting the two double-inward-bent groove rods to form the telescopic ladder, the telescopic ladder is hidden through the supporting pipe connected to a front frame, and conveying and using of maintenance and repair personnel are facilitated.
一种窨井作业伸缩爬梯的应用,涉及一种窨井爬梯,伸缩爬梯包括多层双内折弯槽杆(10)和脚踏板(8)形成的U形滑动体,两双内折弯槽杆下端设置的两下延伸板(15)之间设有脚踏板,两组螺丝的螺杆A(17)分别由下延伸板的两光孔(20)外侧穿入后连接脚踏板的两螺孔(57),两双内折弯槽杆的上端内侧分别设有凸起块(9),凹槽(11)口的内侧分别设有内凸起条(12)形成一层U形滑动体;多层U形滑动体两双内折弯槽杆相互连接;最上部的两双内折弯槽杆上端固定连接支撑管(2)的中部;本发明利用多层U形滑动体两双内折弯槽杆相互连接形成伸缩爬梯,由连接在前框架的支撑管获取伸缩爬梯的隐藏,方便了维护检修人员的运送和使用。
