Abstract
The utility model discloses a secondary locking mechanism of an underwater horizontal connector installation tool. The secondary locking mechanism comprises a rack, a gear, a gear fixing shaft and a locking head. The gear is fixed on the gear fixing shaft. When the rack and the gear move in a meshed mode, the gear fixing shaft rotates under the effect of the gear. A compression spring is arranged in a cavity in the gear fixing shaft. The locking head is arranged at one end portion of the gear fixing shaft and extends out of the gear fixing shaft. The locking head can move in the axial direction of the gear fixing shaft under the elastic force effect of the compression spring. According to the secondary locking mechanism of the underwater horizontal connector installation tool, the ROV assistance is not required, and automatic locking can be achieved in the installation process. Due to the fact that the locking head is of a special cylindrical structure, the firmness degree after the locking is ensured, and the reliability degree of a whole connector is improved.
Description
Technical field
The utility model relates to a kind of secondary locking mechanism of submerged level connector erecting tools.
Background technology
The at present exploitation in deep water gas field be investment high, have a big risk and energy industry frontier that new and high technology is intensive.Wherein the locking of subsea manifold connector is a kind of key technology in deep water gas field development process.Especially guarantee especially as the secondary locking that is not easy to operation the technological challenge that manifold firmly connects, can this technical barrier break through the direct exploitation that affect the deep water gas field smoothly.
The utility model content
The purpose of this utility model is to provide a kind of secondary locking mechanism of submerged level connector erecting tools, and described secondary locking mechanism is without the ROV operation, and easy to operate, automaticity is high.
The secondary locking mechanism of submerged level connector erecting tools provided by the utility model, it comprises tooth bar, gear, gear fixed axis and locking head;
Described gear is fixed on described gear fixed axis; When described tooth bar and described gear gear motion, described gear fixed axis is rotated under the effect of described gear;
Be provided with Compress Spring in the cavity of described gear fixed axis;
Described locking head is located at an end of described gear fixed axis, and extends to outside described gear fixed axis; Described locking head can move by the axial direction along described gear fixed axis under the elastic force effect of described Compress Spring.
In above-mentioned secondary locking mechanism, described secondary locking mechanism also comprises at least 1 frizzen, and an end of described frizzen is fixed with baffle plate; Described trigger head can be located on described baffle plate, in position fixing process, by described frizzen by described baffle plate move to fastening bolt on connector directly over, and then mobile described baffle plate, described locking head returns vertically and falls in fastening bolt.
The utlity model has following beneficial effect:
1, auxiliary without ROV, automatic locking in installation process.
2, automaticity is high.Displacement transmission, spring force transmission, rack-and-pinion transmission by baffle plate will be unfavorable for that the secondary locking of ROV operation is transformed into the mechanically operated secondary locking of dependence.
3, lock firm.Locking head adopts special column construction, has guaranteed the firm degree after locking, has improved the degree of reliability of whole connector.
The accompanying drawing explanation
Fig. 1 is the stereogram of the utility model secondary locking mechanism.
Fig. 2 is the sectional view of the utility model secondary locking mechanism.
Fig. 3 is the structural representation of flush deck socket in the utility model embodiment.
Fig. 4 is the structural representation of erecting tools in the utility model embodiment.
Fig. 5 is the schematic diagram of the utility model secondary locking mechanism while coordinating with connector.
In figure, each mark is as follows:
1 frizzen, 2 tooth bars, 3 gears, 4 baffle plates, 5 locking posts, 6 locking cone pieces, 7 fastening bolts, 8 gear fixed axis, 9 Compress Springs, 10 location-plates, 11 drive plates, 12 centering plates, 13 driving rings, 14 locking heads.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further, but the utility model is not limited to following examples.
As depicted in figs. 1 and 2, the secondary locking mechanism that the utility model provides comprises tooth bar 2, gear 3, gear fixed axis 8 and locking head 14; Its middle gear 3 is fixed on gear fixed axis 8, while moving under the driving effect of the drive plate 11 when tooth bar 2 on erecting tools, can mesh with gear 3, and under this gear motion, gear fixed axis 8 can be along with gear 3 is rotated.
As shown in Figure 2, be provided with Compress Spring 9 in the cavity of this gear fixed axis 8, locking head 14 is located at an end of gear fixed axis 8, and extends to outside gear fixed axis 8; Locking head 14 can move by the axial direction along gear fixed axis 8 under the elastic force effect of Compress Spring 9, so that locking head 14 contacts with the fastening bolt 7 on connector all the time.
The secondary locking mechanism that the utility model provides comprises 2 frizzens 1 and the baffle plate 4 be connected with an end of frizzen 1, the effect that these parts are set is location: before carrying out secondary locking, by locking head 14 grades partly be located at baffle plate 4 above, after once locking finishes, by mobile frizzen 1 make baffle plate be positioned at fastening bolt 7 directly over, then withdraw baffle plate 4, locking head 14 can fall in fastening bolt 7.
While using secondary locking of the present utility model mechanism to carry out secondary locking to flush deck socket, can carry out according to following step:
As shown in Fig. 3, Fig. 4 and Fig. 5, when connector, in smart centering process, frizzen 1 can promote baffle plate 4, and locking head 14, under the effect of Compress Spring 9, sticks in the cone tank of bolt of connector fixed 7, and the groove of locking head 14 inside is stuck in fastening bolt 7 tops.After connector completes once locking, drive plate 11 is withdrawn to the direction of centering plate 12, while reaching ad-hoc location, is fixed on drive plate 11 tooth bar 2 and gear 3 engagements, and then promotes gear 3 rotations.Locking head 14 rotates under the drive of gear 3, and the while, under the effect of the elastic force of Compress Spring 9, moves down, thereby turns fastening bolt 7.The fastening bolt 7 that is rotated down motion drives locking cone piece 6 and moves downward, and through locking cone piece 6 and the taper fit of locking on post 5, has completed the secondary locking process of connector.
The various embodiments described above are only for illustrating the utility model; wherein the structure of each parts, connected mode etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
