Problems solved by technology

[0002] The ram blowout preventer and the drilling spool need to be turned over from 0 to 90 degrees during maintenance or cleaning. The current method used is to use lifting machinery combined with manual turning. Small and light ram blowout preventers and drilling spools It is easier to turn over the spool, but the large ram blowout preventer and drilling spool weigh a lot, some can reach 10 to 20 tons, and it is time-consuming and laborious to turn over. The cost of equipment such as blowout preventer and drilling spool It is very high, and some are castings. A slight bump caused by carelessness will cause the entire equipment to be scrapped. It is difficult to guarantee safety and reliability. At present, there is no special tool for flipping the ram blowout preventer and drilling spool during maintenance or cleaning. equipment, the safety of construction cannot be guaranteed

Embodiment Construction

[0011] Such as figure 1 , figure 2 As shown, it includes a base 1, a load-bearing overturn frame 2, a hydraulic overturn cylinder 3, a hydraulic station assembly 4 and an electric control device 5, the load-bearing overturn frame 2 is horizontally hinged on the base 1, and the cylinder body 31 of the hydraulic overturn cylinder 3 is hinged on the On the base 1, the end of its piston rod 32 is hinged with the load-bearing overturn frame 2. The push-pull load-bearing overturn frame 2 turns over, and the hydraulic overturn cylinder 3 is connected with the hydraulic station assembly 4 through the high-pressure oil pipeline. The hydraulic station assembly 4 and the electric control Device 5 is connected.

[0012] The load-bearing overturn frame 2 is a cross-sectional L-shaped body formed by connecting the first load-bearing plate 21 and the second load-bearing plate 22 perpendicular to each other on one side. Ribs 23 are connected between the first bearing plate 21 and the seco...

Abstract

The invention relates to a petroleum machinery maintenance device, in particular to a blowout preventer turning system for turning a blowout preventer during maintenance and cleaning. The blowout preventer turning system comprises a base (1), a bearing turning frame (2), a hydraulic tuning oil cylinder (3), a hydraulic station assembly (4) and an electric control device (5); the bearing turning frame (2) is transversely hinged on the base (1); the cylinder body (31) of the hydraulic tuning oil cylinder (3) is hinged on the base (1), and the end part of the piston rod (32) of the hydraulic tuning oil cylinder (3) is articulated with the bearing turning frame (2) to push and pull the bearing turning frame (2) to turn; the hydraulic tuning oil cylinder (3) is connected with the hydraulic station assembly (4) through a high-pressure oil pipeline; and the hydraulic station assembly (4) is connected with the electric control device (5). The blowout preventer turning system is time-saving and labor-saving to use, safely and reliably turns a ram preventer, a drill spool and other heavy devices in maintenance or cleaning, improves the production efficiency, ensures safe production and fills a blank in the blowout preventer maintenance field at home and abroad.
