The invention discloses a protection device for pipeline inspection. The protection device for pipeline inspection comprises a rod part, an abutting part and two pulleys, wherein the abutting part comprises a first plate and a second plate, the first plate is arranged at one end of the rod part, the second plate is arranged on the opposite side of the rod part relative to the first plate, and an included angle of 30-90 degrees is formed between the first plate and the rod part; and the two pulleys are arranged on the second plate, and the connecting line of the axes of the two pulleys has an angle of 10-80 degrees relative to the rod part. The abutting part of the protection device for pipeline inspection can abut against the side wall of a pipeline, then a steel wire rope is wound aroundthe pulleys, and thus abrasion caused to the side wall of the pipeline by the steel wire rope is avoided.
本发明公开了一种用于管道检查的保护装置,其包括:杆部;抵接部,所述抵接部包括第一板和第二板,所述第一板设于所述杆部的一端,所述第二板相对于所述第一板设于所述杆部的相反侧,所述第一板与所述杆部呈30°‑90°角;两个滑轮,两个所述滑轮设于所述第二板上,两个所述滑轮的轴心的连线相对于所杆部的角度为10°‑80°。该用于管道检查的保护装置的抵接部可以抵接于管道的侧壁,从而钢丝绳绕于滑轮,从而避免钢丝绳对管道的侧壁的磨损。
