Description
Technical field
The utility model relates to oil-well rig boring tower locking device, particularly a kind of derrick locking device active block stop.
Background technology
Drilling derrick locking device block is the safety device of the locked U-shaped ring of oil-well rig boring tower.The protector come off is gone here and there after being specifically designed to protection derrick locked U-shaped ring.Traditional drilling derrick locking device block is directly welded on lock and man-like shelf support body by block, and this structure, is easily caused danger at derrick lifting or when falling due to work high above the ground dismounting locking device (U-shaped ring) operation inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of structure derrick locking device active block stop simple, easy to use, safe.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of derrick locking device active block stop, combined by fixing otic placode, axis of rotation, block, location otic placode, alignment pin, described block is L-type, the minor face of block is connected in the middle of two fixing otic placodes by axis of rotation, axis of rotation is by bolton, the long limit of block is connected on the otic placode of location by alignment pin, fixes otic placode and fixes at derrick man-like shelf, and location otic placode is fixed on the locked ear post of derrick.
Described alignment pin is loose pin, can freely extract and insert.
Compared with prior art, the beneficial effects of the utility model are:
The utility model in use easy to operate, safety is high, structure is simple, effectively raises operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is upward view of the present utility model.
In figure: 1-axis of rotation 2-fixes otic placode 3-block 4-and locates otic placode 5-alignment pin 6-derrick locked ear post 7-U type ring 8-bolt
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further illustrated:
As shown in Figure 1 and Figure 2, a kind of derrick locking device active block stop, combined by fixing otic placode 2, axis of rotation 1, block 3, location otic placode 4, alignment pin 5, block 3 is in L-type, the minor face of block 3 is connected in the middle of two fixing otic placodes 2 by axis of rotation 1, axis of rotation 1 is fastening by bolt 8, the long limit of block 3 is connected on the otic placode 4 of location by alignment pin 5, alignment pin is loose pin, can freely extract and insert, fix otic placode 2 and fix at derrick man-like shelf, location otic placode 4 is fixed on the locked ear post 6 of derrick.
When derrick lifting terminates rear installation derrick locking device, alignment pin is extracted rotary block and derrick locking device is installed, after installation, block is rotated back to fixing otic placode place and the locked block of alignment pin is installed.
Be only general principle of the present utility model above, not impose any restrictions the utility model, every foundation the utility model carries out equivalent variations and modification to it, all within the category of the art of this patent protection scheme.
