Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.
[0029] like Figure 1-Figure 5 As shown, the secondary locking mechanism provided by the present invention includes a rotating mechanism and a locking mechanism; the rotating mechanism includes a tool rack 2, a tool gear 10, a bevel gear a15 and a bevel gear b9 (not marked in the figure); wherein, the tool One end of the rack 2 is fixed on the drive plate 17 of the installation tool by the rack holder 1, as Figure 7 and Figure 8 shown. The tool gear 10 is connected coaxially with the bevel gear a15, the bevel gear a15 is vertically connected with the bevel gear b, and the bevel gear a15 and the bevel gear b are arranged in a tool box 7, and the tool box 7 is fixed on a fixed On the plate 6, the fixed plate 6 is fixed on the installation tool by bolts 9. When the drive plate 17 drives the tool ...

The invention discloses a secondary locking mechanism of an underwater horizontal connector mounting tool. The secondary locking mechanism comprises rotary mechanisms and locking mechanisms, and each rotary mechanism comprises a tool rack, a tool gear, a bevel gear a and a bevel gear b, wherein the tool gear is coaxially connected with the bevel gear a which is perpendicularly connected with the bevel gear b. When each tool rack and the corresponding tool gear are in meshed movement, the corresponding bevel gear a rotates in a plane parallel to the tool gear, and the corresponding bevel gear b rotates in a plane perpendicular to the tool gear. Each locking mechanism comprises a locking head and a cylinder, a fixed end of each locking head is fixed on the corresponding cylinder through a locking pin, each cylinder is provided with a strip-shaped slot, each locking pin can move along the corresponding strip-shaped slot, a tool spring is arranged in each cylinder and can push each locking head to move, and the cylinders are connected with fixing shafts of the bevel gears b. The secondary locking mechanism changes secondary locking non-beneficial to ROV (remote operated vehicle) operation into secondary locking depending on mechanical transmission by means of stop plate displacement transmission, spring force transmission and gear and rack transmission.
Description
technical field [0001] The invention relates to a secondary locking mechanism of an underwater horizontal connector installation tool. Background technique [0002] At present, the development of deep-water gas fields is a new field of energy industry with high investment, high risk and high-tech intensive. Among them, the locking of the subsea manifold connector is a key technology in the development of deep water gas fields. In particular, the secondary locking, which is inconvenient to operate, is a technical challenge to ensure the firm connection of the manifold. Whether this technical problem can be successfully broken through will directly affect the development and utilization of deep-water gas fields. Contents of the invention [0003] The purpose of the present invention is to provide a secondary locking mechanism of an underwater horizontal connector installation tool, which does not require ROV operation, is easy to operate, and has a high degree of automation...
