Engineering acceptance inspection device

The invention relates to the technical field of measuring instruments. The engineering acceptance inspection device comprises a base, a fixing plate and a rope, the fixing plate is provided with a take-up and pay-off mechanism used for taking up and paying off the rope, the rope is provided with a plumb bob, and the movement direction of the plumb bob is perpendicular to the fixing plate, and the engineering acceptance inspection device is characterized in that the base is provided with a fixing table, and the fixing plate is perpendicularly and fixedly connected to the fixing table; the rope penetrates through the cylinder, the adjusting mechanism is used for driving the cylinder to move vertically, the outer diameter of the cylinder is smaller than the width of the plumb bob, and a clamping mechanism used for clamping the rope is arranged on the cylinder. According to the scheme, the problem that a rope and a plumb bob slide when an existing perpendicularity detection device for constructional engineering i
