Abstract
The invention discloses a device for detecting the tightness distance of external threads of a large-caliber casing pipe. The detecting device comprises a gauge bracket. A thread gauge is in transmission connection with the gauge bracket. The gauge bracket is connected with a suspension type balancer. The suspension type balancer is connected with a moving mechanism. The moving mechanism comprises a transverse beam and a stand column. A trolley moving along the length direction can be arranged on the transverse beam. The transverse beam is connected with the stand column through a pin shaft. The suspension type balancer is connected with the trolley. The detecting device disclosed by the invention has the beneficial effects as follows: the thread gauge is overlapped with the center line of the casing pipe to be detected by rotating the transverse beam and pulling the balancer up and down, and is tightly screwed on the outer threads of the casing pipe to be detected, so that the pull force of the balancer cancels a part of the gravity of the thread gauge to reduce the labor intensity of the detectors. Furthermore, the device can be used for avoiding the damage to the threads of the casing pipe, which is caused by the overlarge friction of the own gravity of the thread gauge in the process of tightly screwing the thread gauge with the threads of the casing pipe to be detected.
