Description

Technical Field

[0001] This utility model relates to an automatic lubrication device for steel wire, belonging to the category of oil and gas extraction machinery. Background Technology

[0002] Wireline work is an essential measure in current gas well dynamic monitoring, choke deployment, plunger locking, and production line retrieval processes. Gas wellhead pressures are generally high, requiring dynamic sealing at the wellhead. A packing box is needed at the top of the blowout preventer (BOP). Due to the relatively small weight of the tool string, the friction of the packing box is relatively high, making wireline descent difficult. Therefore, lubricating oil needs to be applied to the wireline during descent to minimize friction while maintaining dynamic sealing performance. One common practice is to immerse the wireline in an oil bath for natural lubrication. However, this method results in excessive lubricating oil dripping onto the well site, BOP, and production tree, causing environmental pollution and wasting a large amount of lubricating oil. It also increases the intensity and difficulty of post-operation cleanup. Another common practice is to manually lubricate the wireline during descent. This method is effective, but it is physically demanding, and the operator must stand next to the wireline, posing safety risks. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic lubrication device for steel wire.

[0004] This utility model is implemented as follows: it consists of a lubricating oil container (1), lead screws (2), nuts (3), flat washers (4), spring washers (5), side switches (6), bottom switches (7), and a soft cloth (8). There are 4 lead screws (2), and 8 sets of nuts (3), flat washers (4), and spring washers (5) that match the lead screws (2). The lubricating oil container (1) has fixing ears on the upper and lower sides, an outlet on the bottom side connected to the side switch (6), and an outlet at the bottom bottom connected to the bottom switch (7). The soft cloth (8) is connected below the bottom switch (7). The lubricating oil container (1) can be moved up and down to adjust its height among the 4 lead screws (2). The 8 sets of nuts (3), flat washers (4), and spring washers (5) that match the lead screws (2) fix the lubricating oil container (1).

[0005] The beneficial effects of this utility model are that the device can be fixed at the outlet of the wire or wire rope of the winch rope guide, with the soft cloth (8) facing the wire or wire rope. When the winch is running, the bottom switch (7) is turned on appropriately, and the lubricating oil in the lubricating oil container (1) slowly seeps into the soft cloth (8). The soft cloth (8) comes into contact with the winch wire or wire rope, so the wire or wire rope is automatically and continuously lubricated by the lubricating oil. The structure is simple, the cost is low, and it is highly practical on site. Attached Figure Description
