Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to Fig. 1, shown in Fig. 3, a kind of air filling type gripping tongs buoyancy body lifting gear, comprise four floating cylinder assemblies 4, described floating cylinder assembly 4 is distributed in buoyancy body both sides symmetrically, two described floating cylinder assemblies 4 of every side are by nylon tube 7, two-way snap joint 5 is connected with threeway snap joint 6 and uses clip 8 to be fixed in described buoyancy body, with described nylon tube 7 between described threeway snap joint 6, one way valve 3 is connected with two-way snap joint 5 and is fixed in described buoyancy body by clip 8, described threeway snap joint 6 connects two-way snap joint 5 on described one way valve 3 and two-way air cock 2 by nylon tube 7 two ends, described two-way air cock 2 other end connects source of the gas 1 by nylon tube 7.
With reference to shown in Fig. 2, state floating cylinder assembly 4 and comprise floating cylinder sleeve 25, described floating cylinder sleeve 25 is fixed in buoyancy body by six the first bolts 14, described floating cylinder sleeve 25 fixes floating cylinder cap 21 by six the second bolts 20, the two ends of described floating cylinder cap 21 are provided with the 3rd O RunddichtringO 24, the center of described floating cylinder cap 21 is provided with plug screw 22, the bottom of described plug screw 22 is provided with combination sealing pad 23, described floating cylinder sleeve 25 inside is provided with floating piston bar 26, described floating cylinder sleeve 25 and the contact wall of described floating piston bar 26 are provided with Yx sealing ring 16 from top to bottom successively, guide ring 13 and dust ring 12.
Floating piston seal cover 27, spring backing pin 11 and buoyancy body spring 10 is provided with from top to bottom successively in described floating piston bar 26, described buoyancy body spring 10 outer race has spring spool 9, fixed by the 3rd bolt 18 between described floating piston seal cover 27 and described spring backing pin 11, the edge of the contact surface of described floating piston seal cover 27 and described spring backing pin 11 is provided with card 15, the both sides of described floating piston seal cover 27 are provided with an O RunddichtringO 17, and the top of described spring backing pin 11 is provided with the 2nd O RunddichtringO 19.
The operating principle of the present embodiment is as follows:
Open two-way air cock 2, compressed air enters floating cylinder sleeve 25 inner chamber through one way valve 3 from the air inlet port of floating cylinder assembly 4, act on floating cylinder cap 21 with on floating piston bar 26 and floating piston seal cover 27, four floating cylinder sleeves 25 are upwards balanced with buoyancy body and rises to extreme position.Then to dismantle the nylon tube 7 of the inlet end be connected with one way valve 3 and threeway snap joint 6, due to the effect of one way valve 3, the gas of floating cylinder sleeve 25 inner chamber can not flow out, now buoyancy body can not decline, the active force being compressed gas due to floating cylinder sleeve 25 inner chamber much larger than active force suffered during buoyancy body spring 10 compression downwards in floating installation, so gripping tongs as casing tong be used in transfer sleeve pipe downward spinner time buoyancy body only compression buoyancy body spring 10 and floating cylinder sleeve 25 is unaffected downwards.When floating cylinder sleeve 25 breaks down and can not inflate, the plug screw 22 on floating cylinder cap 21 can be turned on, then with the screw that bolt precession for subsequent use is floated on cylinder cap 21, with one of bolt for subsequent use directly floating piston seal cover 27 together with floating piston bar 26 jack-up, reach the object of rising buoyancy body.When will use as rotary tong, as long as back down the spool of both sides one way valve 3 with a pin (special tool) of enroute repair kit, the cylinder assembly 4 that now floats is exitted, and buoyancy body declines resets gently, shackle operation on the drilling rod that can carry out routine.
