Description

A wellhead line-passing mechanism

technical field

The utility model belongs to the field of detection of sewage, rainwater, oil, gas and other pipelines, and in particular relates to a wellhead line passing mechanism.

Background technique

In the field of drainage pipeline detection, the detection equipment usually has a long cable connected to the detection unit to provide power and communicate with the controller. When the detection unit advances inside the pipeline, the cable will inevitably rub against the inspection wellhead and the edge of the pipeline. These irregular edges that come into contact with the cable can scratch the cable sheath when pulled quickly with high force. In the long-term friction process, it will cause the cable core to be pulled, resulting in reduced cable life and even damage.

Utility model content

The technical problem to be solved by the utility model is: to provide a wellhead line passing mechanism, which can avoid friction between the cable and the detection well.

The technical solution adopted by the utility model to solve the above technical problems is: a wellhead line passing mechanism, characterized in that it includes a support frame, a pulley and a limit rod; the support frame is horizontal, and the support frame is provided with There is a pulley fixing rod in the horizontal direction, and the pulley is sleeved on the pulley fixing rod; there are at least 3 limit rods, which are connected with the support frame and extend downward for a certain distance. The position of the support frame is such that the position of the limit rod is in the position of the support frame so that the limit rod 1 can just be stuck on the detection well.

According to the above solution, the limit rod is in a vertical direction, the limit rod is slidably connected with the support frame, and the limit rod is provided with a fastener for fixing the limit rod.

According to the above scheme, the support frame includes two first support rods parallel to each other, and a second support rod perpendicular to the first support rods, the second support rod is parallel to the pulley fixed rod, and the second support rod is connected to the pulley The distance between the fixed rods is smaller than the diameter of the detection well; the limit rods are all arranged on the first support rod, and are located outside the second support rod and the pulley fixed rod.

According to the above scheme, the limit rod is provided with a horizontal through hole for the support frame to pass through, and the top of the limit rod is provided with a threaded hole communicating with the through hole, and the fastener is The fastening bolt is connected to the threaded hole, and the length of the fastening bolt is greater than the length of the threaded hole.

The beneficial effects of the utility model are: by winding the cable on the pulley, direct friction between the cable and the irregular edge of the detection well is avoided, the cable is protected, and the service life of the cable is prolonged; The mechanism is stuck at the wellhead to ensure that the whole will not move.
