Please inferior consult Figure 12 again, cylinder body described in the utility model 1 is that the detachable structure of main body 11 and cylinder cap 12 can conveniently be overhauled the utility model hydraulic actuating cylinder 100.Owing to needing sealing between cylinder cap 12 and main body 11, therefore, between described cylinder cap 12 and described main body 11, be also provided with the 3rd seal ring 1a and back-up ring 1b, described cylinder cap 12 is provided with the 3rd seal groove 12a, described the 3rd seal ring 1a and back-up ring 1b are arranged in described the 3rd seal groove 12a, and the internal face of described the 3rd seal ring 1a and described main body 11 is conflicted.Described the 3rd seal ring 1a and back-up ring 1b can be to sealing between described cylinder cap 12 and described main body 11, thereby guarantee the leak tightness of described hydraulic actuating cylinder 100.
Comprehensive foregoing in conjunction with Figure 14, level(l)ing device described in the utility model comprises three described level(l)ing mechanisms 1000, and three described level(l)ing mechanisms 1000 are 120 degree compartment of terrains around the periphery that is arranged at equipment 2000.Three hoist cables on described suspender are connected with the described suspension hook 202a in three described level(l)ing mechanisms 1000 respectively, and described level(l)ing device is as the transition piece 300 of suspender and equipment 2000, the together lifting of participation device 2000.The equipment 2000 being lifted can be the whole bolt stretching machine of reactor or other equipment in nuclear station.
Before starting lifting, described equipment 2000 is positioned on storage facility, and described level(l)ing mechanism 1000 is connected between described equipment 2000 and suspender but equipment 2000 is not sling, therefore described turnbuckle 200 under tension not also now.Operating personal reverses to adjust three described turnbuckles 200 in described level(l)ing mechanism 1000 by craft respectively, to change the relative position of upper screw rod 202 described in described turnbuckle 200 and lower screw rod 203, change the height and position of the relatively described hydraulic actuating cylinder 100 of described suspension hook 202a, thereby carry out levelness coarse adjustment, until levelness meets the demands.
Then connect the power supply of described level(l)ing mechanism 1000, with described suspender, described equipment 2000 is sling, when described equipment 2000 is in nuclear station during the whole bolt stretching machine of reactor, described level(l)ing mechanism 1000 is used in conjunction with containment internal head cover suspender.Before lifting, described upper oil cavitie 13 is full of hydraulic oil, described lower oil cavitie 14 has the hydraulic oil of less hydraulic oil and lower oil duct 32 among certain pressure, therefore, the hydraulic oil of described lower oil duct 32 backs down described sealing plug 52 by described repairing oil duct 33, thereby make described elastic element 51 compressions and open, and hydraulic oil is filled with in described repairing oil duct 33.After lifting, described suspender produces pulling force upwards to described piston rod 2,2000 pairs of described cylinder bodies 1 of described equipment produce downward pulling force, at this moment, hydraulic oil in described upper oil cavitie 13 produces larger hydraulic pressure under the effect of the shaft shoulder 21 of described piston rod 2, thereby stops relatively described piston rod 2 relative slidings of described cylinder body 1.Meanwhile, described lower oil cavitie 14 produces negative pressure, at this moment, 14 pairs of described lower oil cavitie 14 repairings of lower oil cavitie described in hydraulic oil automatic stream in described lower oil duct 32 and repairing oil duct 33, simultaneously, described sealing plug 52 is moved to the junction of described large footpath 33a and path 33b at the application force of described elastic element 51, by described large footpath 33a sealing.At this moment, can support described equipment 2000.Above described equipment 2000 is thus lifted to object height and when levelness does not meet the demands, according to the indication of levelness on the control capsule of described level(l)ing device, press corresponding level-off button, described electromagnetic valve 4 in the described level(l)ing mechanism 1000 of appointment sends instruction, start described electromagnetic valve 4, described electromagnetic valve 4 is opened, at this moment, described upper oil cavitie 13 is communicated with by described upper oil duct 31 and lower oil duct 32 with lower oil cavitie 14, because the pressure in described upper oil cavitie 13 is larger, therefore, hydraulic oil in described upper oil cavitie 13 flows to described lower oil cavitie 14 through described upper oil duct 31 and lower oil duct 32, now, the relatively described piston rod 2 of described cylinder body 1 moves down slowly, thereby make this level(l)ing mechanism 1000 slowly mobile with the junction of described equipment 2000 downwards, according to actual conditions, respectively the described electromagnetic valve 4 of three described level(l)ing mechanisms 1000 is sent to several times instruction, can reach the object of the levelness of equipment 2000 described in accurate adjustment, make described equipment 2000 accurately corresponding with installation site.
When horizontal gradient error has exceeded the setting range of described level(l)ing device, level-off again again after need making described piston rod in described level(l)ing mechanism 1,000 2 adjust to reset.And described piston rod 2 in described level(l)ing mechanism 1000 cannot automatically decline to realizing and resets in tension carrying situation, therefore before resetting, need described equipment 2000 to be reapposed on storage facility, then by the reset button on described control capsule, make described electromagnetic valve 4 keep powered open state always, the upper oil cavitie 13 of hydraulic actuating cylinder 100 is communicated with lower oil cavitie 14, the elastic force that described piston rod 2 relies on Compress Spring 16 described in its deadweights and described upper oil cavitie 13 is the described upper oil cavitie 13 extremely of the hydraulic oil pressure in described lower oil cavitie 14, thereby described piston rod 2 is moved down, realize the reset of making zero of described level(l)ing device.
Compared with prior art, because the utility model is evenly arranged on three described level(l)ing mechanisms 1000 periphery of described equipment 2000, and in described level(l)ing mechanism 1000, be provided with described turnbuckle 200 and described hydraulic actuating cylinder 100, therefore before the described equipment 2000 of slinging, by regulating upper screw rod 202 and the relative position of lower screw rod 203 on described nut 201 described in described turnbuckle 200, can change the height and position of the relatively described hydraulic actuating cylinder 100 of described suspension hook 202a, thereby the height and position of the junction that changes described equipment 2000 and level(l)ing mechanism 1000 by described attaching parts 300 and bearing pin 301 after slinging, when adjusting the described turnbuckle 200 in three described level(l)ing mechanisms 1000 separately respectively, the effect of the levelness after the equipment 2000 described in coarse adjustment of just can playing is sling.After coarse adjustment completes, the described equipment 2000 of slinging, and the switching of the electromagnetic valve 4 by hydraulic actuating cylinder 100 described in a plurality of described level(l)ing mechanisms 1000 of independent adjustment changes the height and position of the relatively described cylinder body 1 of described piston rod, realize the meticulous adjusting to the levelness of described equipment 2000.By above coarse adjustment and meticulous adjusting, can make the accurate corresponding installation site of described equipment 2000, once mounting puts in place, improves lifting, installation effectiveness, avoids installing unsettled situation and occurs.
Above disclosed is only preferred embodiments of the present utility model, its effect is facilitate those skilled in the art to understand and implement according to this, certainly can not limit with this interest field of the utility model, therefore the equivalent variations of doing according to the utility model claim, still belongs to the scope that the utility model is contained.
