Detailed description of the invention
1-5 carries out clear, complete description to technical scheme further below in conjunction with the accompanying drawings.
Embodiment one
Mechanical spring reset mode
See accompanying drawing 1-5, four carrier blocks 1 are one group, many group carrier blocks 1 retain the head tree side being welded in derrick upper body 6 of spacing, locking pin seat 3 is welded on the derrick panel 7 of derrick lower body 14, resetting-mechanism 2 connecting bolt 5 is connected with locking pin seat 3, and the lock pin block 4 in locking pin seat 3 is connected with the piston rod 9 in resetting-mechanism 2.When the telescopic oil cylinder 8 on derrick normally works, being filled with hydraulic oil in the hydraulic oil of oil connection 12 entrance makes reset cylinder body 10, piston rod 9 is in poised state, and the back-moving spring 11 of jacking block 13 end is in compressive state.When the telescopic oil cylinder 8 hoisted lost efficacy, the fluid pressure line that the hydraulic oil pipeline of telescopic oil cylinder 8 connection and resetting-mechanism 2 connect decompression simultaneously, now, owing to the oil pressure in reset cylinder body 10 disappears, back-moving spring 11, under the effect of elastic force, promotes jacking block 13 to be released by piston rod 9, and the lock pin block 4 being contained in locking pin seat 3 is released by piston rod 9, the carrier block 1 of welding on the head tree of derrick upper body 6 is allowed to be supported on above lock pin block 4, it is achieved that to prevent falling downwards of derrick upper body 6.
When telescopic oil cylinder 8 is resumed work, the oil pressure in reset cylinder body 10 promotes back-moving spring compression return, simultaneously piston rod 9 band pendulum lock pin block 4 return, and the work that hoists of derrick upper body 6 is completed by telescopic oil cylinder 8.
