Embodiment
1-5 further carries out clear, complete description to technical scheme below in conjunction with the accompanying drawings.
Embodiment one
Mechanical spring reset mode
Referring to accompanying drawing 1-5, four carrier blocks 1 are one group, and multigroup carrier block 1 retains the master for being welded in derrick upper body 6 of spacing
Column side, locking pin seat 3 are welded on the derrick panel 7 of derrick lower body 14, resetting-mechanism 2 connecting bolt 5 and the phase of locking pin seat 3
Connect, the lock pin block 4 in locking pin seat 3 is connected with the piston rod 9 in resetting-mechanism 2.When the 8 normal work of telescopic oil cylinder on derrick
When making, the hydraulic oil entered from oil connection 12 makes to be filled with hydraulic oil in reset cylinder body 10, and piston rod 9 is in poised state,
The back-moving spring 11 of the end of jacking block 13 is in compressive state.When the telescopic oil cylinder 8 of raising fails, what telescopic oil cylinder 8 connected
The fluid pressure line while decompression that hydraulic oil pipeline and resetting-mechanism 2 connect, now, because the oil pressure resetted in cylinder body 10 disappears,

The carrier block 1 connect is supported on above lock pin block 4, and realizing prevents falling downwards for derrick upper body 6.Now jacking block 13 is act as
According to the telescopic piston of pressure change in reset chamber 15.
When telescopic oil cylinder 8 is resumed work, reset cylinder body 10 in oil pressure returned to the oil pressure in reset chamber 15 it is identical,
Now piston rod 9 is completed with the return of pendulum lock pin block 4, the raising work of derrick upper body 6 by telescopic oil cylinder 8.
Embodiment three
It is pneumatic to promote reset mode
Referring to accompanying drawing 1-4 and Fig. 6, when 8 normal work of telescopic oil cylinder on derrick, pass through compressed air in reset chamber 15
Import 16 is full of compressed air, connects hydraulic oil pipeline that the pressure in reset chamber 15 is connected with telescopic oil cylinder 8 and resetting-mechanism 2
The pressure in fluid pressure line connect is identical, and piston rod 9 is in poised state, and when the telescopic oil cylinder 8 of raising fails, stretch oil
The fluid pressure line while decompression that the hydraulic oil pipeline and resetting-mechanism 2 that cylinder 8 connects connect, now, due to resetting in cylinder body 10
Oil pressure disappears, and now, because the oil pressure resetted in cylinder body 10 disappears, jacking block 13 moves in reset chamber 15 in the presence of pressure,
Jacking block 13 will promote piston rod 9 to move, and piston rod 9 releases the lock pin block 4 in locking pin seat 3, allows the head tree of derrick upper body 6
The carrier block 1 of upper welding is supported on above lock pin block 4, and realizing prevents falling downwards for derrick upper body 6.The now work of jacking block 13
With in the reset chamber 15 according to the telescopic piston of pressure change.
When telescopic oil cylinder 8 is resumed work, reset cylinder body 10 in oil pressure returned to the air pressure in reset chamber 15 it is identical,
Now piston rod 9 is completed with the return of pendulum lock pin block 4, the raising work of derrick upper body 6 by telescopic oil cylinder 8.
Described above is only the non-limiting embodiment of invention, substantial amounts of embodiment can also be derived, for this area
