Description

Technical Field

[0001] The utility model belongs to the technical field of safe climbing equipment at oilfield production and well repair sites, and particularly relates to a portable fixed-pole climbing operating platform. Background Art

[0002] The removal and installation of the rope hanger for the oil wellhead pumping unit are the first and last steps in oil and water well operations, respectively, making safety crucial. During the rope hanger removal and installation process, workers need to hammer the polished rod slips and tighten the polished rod square clip bolts with a wrench. This is especially true during workover and completion operations, where workers often need to remove and reattach the polished rod elevator.

[0003] The dynamic height between the pumping unit's suspension rope and the ground greatly increases the difficulty of the above operations. The rope hanger height usually has the following three states: 1. Optimal operating position: When the pumping unit's donkey head is at the bottom dead center, the rope hanger is about 2 meters above the ground. At this time, the operator can complete the above operations while standing on the wellhead tee. 2. The rope hanger is at the midpoint of the pumping unit's stroke: During well repair operations, in order to prevent the pumping unit's donkey head from hitting the downhole swimming system and affecting normal well repair operations, the pumping unit's crossbeam is usually stationary in a position parallel to the ground, and then the rope hanger is removed and the donkey head is hit. At this time, the rope hanger is about 3.2 meters above the ground, and auxiliary tools are required to complete the installation and removal of the rope hanger. 3. The position of the rope hanger between the midpoint and top dead center of the pumping unit's stroke: When the pumping unit is in the no-load state, the donkey head is affected by the tail balance block and is at the top dead center. When the pumping unit belt is loose, it is difficult to hit the donkey head to the balance point after starting the pumping unit. At this time, the rope hanger is about 4 meters above the ground, and auxiliary tools are also required to complete the installation and removal of the rope hanger.

[0004] When adjusting the anti-impact distance at the oil wellhead and hanging the bare rod, when the height of the rope hanger exceeds 2 meters from the ground, there is a lack of safe and reliable auxiliary tools at the oil production and well repair sites. The installation and removal of the pumping unit rope hanger is time-consuming and labor-intensive, and there are great safety hazards. Utility Model Content
