Detailed description of the invention
1-5 carries out clear, complete description to the technical solution of the utility model further below in conjunction with the accompanying drawings.
Embodiment one
Mechanical spring reset mode
Seeing accompanying drawing 1-5, four carrier blocks 1 are one group, and many group carrier blocks 1 retain the master being welded in derrick upper body 6 of spacing
Column side, locking pin seat 3 is welded on the derrick panel 7 of derrick lower body 14, resetting-mechanism 2 connecting bolt 5 and locking pin seat 3 phase
Connecting, the lock pin block 4 in locking pin seat 3 is connected with the piston rod 9 in resetting-mechanism 2.When the normal work of telescopic oil cylinder 8 on derrick
When making, 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,
The back-moving spring 11 of jacking block 13 end is in compressive state.When the telescopic oil cylinder 8 hoisted lost efficacy, telescopic oil cylinder 8 connects
The fluid pressure line that hydraulic oil pipeline 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, the lock pin that piston rod 9 will be contained in locking pin seat 3
Block 4 is released, and allows the carrier block 1 of welding on the head tree of derrick upper body 6 be supported on above lock pin block 4, it is achieved that to prevent derrick upper body 6
Fall downwards.
When telescopic oil cylinder 8 is resumed work, the oil pressure in reset cylinder body 10 promotes back-moving spring compression return, simultaneously piston
Bar 9 band pendulum lock pin block 4 return, the work that hoists of derrick upper body 6 is completed by telescopic oil cylinder 8.

Mouthfuls 16 fill hydraulic oil, make hydraulic oil pipeline that the pressure in reset chamber 15 is connected and resetting-mechanism 2 connection with telescopic oil cylinder 8
Pressure in fluid pressure line is identical, and piston rod 9 is in poised state, when the telescopic oil cylinder 8 hoisted lost efficacy, and telescopic oil cylinder 8
The fluid pressure line that the hydraulic oil pipeline connected and resetting-mechanism 2 connect decompression simultaneously, now, due to the oil pressure in reset cylinder body 10
Disappearing, now, owing to the oil pressure in reset cylinder body 10 disappears, jacking block 13 moves under the effect of pressure in reset chamber 15, jacking block
Promotion piston rod 9 is moved by 13, and the lock pin block 4 being contained in locking pin seat 3 is released by piston rod 9, allows and welds on the head tree of derrick upper body 6
The carrier block 1 connect is supported on above lock pin block 4, it is achieved that prevent falling downwards of derrick upper body 6.Now the acting as of jacking block 13
Telescopic piston is changed according to pressure in reset chamber 15.
When telescopic oil cylinder 8 is resumed work, the oil pressure in reset cylinder body 10 returns to identical with the oil pressure in reset chamber 15,
Now piston rod 9 band pendulum lock pin block 4 return, the work that hoists of derrick upper body 6 is completed by telescopic oil cylinder 8.
Embodiment three
Pneumatic promotion reset mode
See accompanying drawing 1-4 and Fig. 6, when the telescopic oil cylinder 8 on derrick normally works, in reset chamber 15, pass through compressed air
Import 16 is full of compressed air, makes hydraulic oil pipeline that the pressure in reset chamber 15 is connected and resetting-mechanism 2 with telescopic oil cylinder 8 even
Pressure in the fluid pressure line connect is identical, and piston rod 9 is in poised state, when the telescopic oil cylinder 8 hoisted lost efficacy, and flexible oil
The fluid pressure line that the hydraulic oil pipeline of cylinder 8 connection and resetting-mechanism 2 connect decompression simultaneously, now, due in reset cylinder body 10
Oil pressure disappears, and now, owing to the oil pressure in reset cylinder body 10 disappears, jacking block 13 moves under the effect of pressure in reset chamber 15,
Promotion piston rod 9 is moved by jacking block 13, and the lock pin block 4 being contained in locking pin seat 3 is released by piston rod 9, allows derrick upper body 6 head tree
The carrier block 1 of upper welding is supported on above lock pin block 4, it is achieved that prevent falling downwards of derrick upper body 6.The now work of jacking block 13
With for changing telescopic piston according to pressure in reset chamber 15.
When telescopic oil cylinder 8 is resumed work, the oil pressure in reset cylinder body 10 returns to identical with the air pressure in reset chamber 15,
Now piston rod 9 band pendulum lock pin block 4 return, the work that hoists of derrick upper body 6 is completed by telescopic oil cylinder 8.
The above is only the non-limiting embodiment of invention, it is also possible to derive substantial amounts of embodiment, for this area
Those of ordinary skill for, without departing from the invention design with on the premise of not making creative work, it is also possible to do
Going out the embodiment of some deformation and improvement, these broadly fall into protection domain of the present utility model.
