Description
Technical field
The utility model relates to the matched derrick of oil drilling and extracting equipment swing up substructure and A-frame structure more particularly to wells
The connection locking device of frame and A-frame.
Background technique
Transporting to related drilling-production equipment behind oil field before oil-gas mining needs in-site installation that could use, for revolving lift-type bottom
For seat and the derrick to match, A-frame, need for A-frame to be first fixed on pedestal, subsequent derrick telescoping works as well
Erect and be close on A-frame after rising vertical position, worker climbs to high level, stand derrick on interim mounting platform with U-shape lock and
A-frame locking, prevents tipping after derrick from falling, last raising pedestal.In the process, worker needs to install in 8~12 meters of high-altitudes
Than heavier U-shape lock, installment work platform is then dismantled, after the completion of oil-gas mining, is still needed to when dismantling a whole set of drilling-production equipment
Repeat the above work, not only risk is high for the work of this part, and working efficiency is low, brings not to on-site installation work
Just.
Utility model content
In order to solve deficiency in the prior art, one kind is provided and does not need operation of manually climbing, can be realized and risen in derrick
Derrick is connected to the locking device of locking with A-frame automatically after rising, the technical scheme adopted by the utility model is
A kind of derrick and A-frame forced locking device, including derrick and A-frame are equipped with lock on the A-frame
Tight column, on the derrick be equipped with lock column, be movably set on the lock column can fasten it is L-shaped in locking post
Locking bar, being equipped on the derrick makes the locating part of locking bar Yu derrick keeping parallelism, and suction is equipped on the locating part
The firmly magnet of locking bar, the locating part are placed in side of the locking bar far from A-frame, and Contact plate is equipped on the locking bar,
The A-frame is equipped with and can contact Contact plate and make the movable mandril of locking bar.
Bearing is equipped on the lock column, the locking bar is fixed on bearing outer ring.
It is recessed in the locking bar and locking post contact site equipped with cambered surface.
The locking post is symmetrical arranged a pair in A-frame two sides, the lock column, locking bar, locating part, Contact plate,
Mandril and bearing are symmetrical arranged a pair of in derrick two sides.
It is raised to behind vertical position locking bar using the derrick of the structure and just can be toppled over towards A-frame side by being self-possessed rising,
To which fastening makes A-frame connect locking with derrick in the locking post of A-frame, in order to avoid locking bar cannot be by being self-possessed to people
Realization locking is toppled in cabinet frame side, mandril is arranged on A-frame, when the vertical position pushing rod of derrick lifting touches the touching of locking bar
Plate driving locking bar, which is toppled over, completes locking action；The risk of worker's high altitude operation is avoided with this configuration, and improves installation
Efficiency.
Detailed description of the invention
Fig. 1 is that the utility model derrick draws high preceding status diagram；
Fig. 2 is that derrick draws high plumbness schematic diagram；
Fig. 3 locks institute's status diagram for derrick and A-frame；
Fig. 4 is partial enlarged view at A in Fig. 2.
Specific embodiment
Present solution provides a kind of derrick and A-frame forced locking device are as shown in Figure 1 to Figure 3, including derrick 1 and people
Cabinet frame 2 is equipped with locking post 3 on A-frame 2, and lock column 4 is equipped on derrick 1, is movably set with locking bar 5 on lock column 4,
Locking bar 5 is L-shaped, and locking bar 5 can be rotated around lock column 4, and locking bar 5 is protected when derrick is not drawn high also as shown in Figure 1
Hold it is parallel with derrick 1, in order to avoid derrick 1 hangs down in hour locking lever 5 of droping to the ground in gravity, on derrick 1 be equipped with locating part 6,
The locating part 6 is located at locking bar 5 far from 2 side of A-frame, so that derrick 1 is able to maintain locking bar 5 and derrick 1 droping to the ground
In parallel, it is equipped with the magnet that locking bar 5 is sucked on locating part 6, magnet is set in order to avoid the setting of locking bar center of gravity is unreasonable, in derrick
1 just topples over towards A-frame and cannot achieve self-locking when drawing high in place not yet.When derrick 1 draws high vertical locking bar 5 later
It can be toppled over by the gravity of itself towards 2 side of A-frame, but in order to avoid locking bar 5 can not by the magnetic force attraction of magnet
Topple over, a Contact plate 7 is equipped on locking bar 5, which is arranged far from 5 free end side of locking bar, sets on A-frame 2
There is mandril 8, just can be contacted on Contact plate 7 when derrick 1 is erected with pushing rod 8, just can be driven so as shown in Figure 2
Locking bar 5, which is detached from magnet suction, topples over to realize that lock is acted towards A-frame side, is finally reached A-frame as shown in Figure 3
2 and derrick 1 lock effect.
As shown in Figure 4 in order to which the rotation of locking bar 5 can be made more smooth, it is provided with bearing 9 on lock column 4, and locking bar 5 is then
It is fixed on 9 outer ring of bearing, while to avoid locking bar 5 from being buckled in locking post the play of skidding later, being connect on locking bar 5 with locking post 3
Cambered surface recess 10 is arranged in contact portion position, and cambered surface recess 10 is matched with 3 outer profile of locking post.
Locking device above is symmetrical arranged a pair in A-frame 2 and 1 two sides of derrick, can guarantee to be connected firmly and make by
Power is balanced.
