The non-destructive disassembly hydraulic nut comprises a positioning ring (1), an adjustment ring (2), a locking nut (4), a pressure piston (5), a pressure body (7), a piston rod (10) and an oil pump high-pressure connector (12), wherein the oil pump high-pressure connector (12) is connected with the pressure body (7); the pressure body (7) is connected with the pressure piston (5); the pressure piston (5) is connected with the piston rod (10); the positioning ring (1) is arranged on the pressure piston (5); the adjustment ring (2) is connected with the positioning ring (1); the locking nut (4) is connected with the pressure piston (5). Compared with the prior art, the non-destructive disassembly hydraulic nut has the advantages of non-destructive disassembly and the like.
Description
Technical field
The utility model relates to a kind of hydraulic nut, especially relates to a kind of nondestructive demounting hydraulic nut.
Background technique
At present the piston rod of a lot of large reciprocating compressors is connected with crosshead and all adopts hydraulic nut connection.This Placement can provide very large pretightening force and structure small and exquisite, convenient disassembly under normal circumstances, and linkage structure is more complicated, with high content of technology, also higher for installation requirement.But this hydraulic nut also exists a drawback, if exactly in unloading process the aging a variety of causes that waits of the Sealing of oil hydraulic cylinder the inside cause hydraulic fluid leak pressure to stamp, this hydraulic nut just cannot be dismantled.Final method is destroyed hydraulic nut protection piston rod exactly.
Model utility content
The purpose of this utility model is exactly to provide a kind of nondestructive demounting hydraulic nut in order to overcome the defect of above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of nondestructive demounting hydraulic nut, it is characterized in that, comprise positioning ring, adjustment ring, locking nut, pressure piston, pressure body, piston rod and oil pump high pressure joint, described oil pump high pressure joint is connected with pressure body, described pressure body is connected with pressure piston, and described pressure piston is connected with piston rod, and described positioning ring is located on pressure piston, described adjustment ring is connected with positioning ring, and described locking nut is connected with pressure piston.
Described adjustment ring is connected with positioning ring by screw.
Between described pressure piston and pressure body, be provided with seal ring.
Described pressure piston is provided with thrust ring, and this thrust ring is provided with linking springs.
Described pressure body is provided with the pin being connected with pressure piston.
Compared with prior art, at hydraulic nut Sealing, damage leakage of oil, in situation about cannot lay with high pressure oil pump, the utlity model has the advantage of not damaged dismounting.
Accompanying drawing explanation
The structural representation that Fig. 1 hydraulic nut connects;
The structural representation of Fig. 2 the utility model unloading process;
Wherein: 1, positioning ring; 2, adjustment ring; 3, screw; 4, locking nut; 5, pressure piston; 6 seal rings; 7, pressure body; 8, linking springs; 9, thrust ring (two halves); 10 piston rods; 11 pins; 12 oil pump high pressure joints; 13, flywheel; 14, second piston; 15, steel plate parallels; 16, first stage piston.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.The present embodiment be take technical solutions of the utility model and is implemented as prerequisite, provided detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment
As shown in Figure 1, a kind of nondestructive demounting hydraulic nut, comprise positioning ring 1, adjustment ring 2, locking nut 4, pressure piston 5, pressure body 7, piston rod 10 and oil pump high pressure joint 12, described oil pump high pressure joint 12 is connected with pressure body 7, described pressure body 7 is connected with pressure piston 5, and described pressure piston 5 is connected with piston rod 10, and described positioning ring 1 is located on pressure piston 5, described adjustment ring 2 is connected with positioning ring 1, and described locking nut 4 is connected with pressure piston 5.
Described adjustment ring 2 is connected with positioning ring 1 by screw 3.
Between described pressure piston 5 and pressure body 7, be provided with seal ring 6.
Described pressure piston 5 is provided with thrust ring 9, and this thrust ring 9 is provided with linking springs 8.
Described pressure body 7 is provided with the pin 11 being connected with pressure piston 5.
The method for dismounting of the utility model nondestructive demounting hydraulic nut, the method comprises the following steps:
1) dismantle by two air valves of crosshead;
2) in cylinder interior, put into the steel plate parallels 15 that 15-20mm is thick (thickness is greater than rear stop gap more than 5 times);
3) hand turning makes steel plate parallels 15 be fixed by first stage piston 16 and casing wall;
4) (the maximum strength of piston of 6M40 type is 40 tons above flywheel 13, to hang a guide chain, as long as so the guide chain that is no more than 40 tons can be used) by guide chain, draw flywheel to carry out jiggering to force piston rod 10 afterbodys to produce elastic stretchings distortion, until hydraulic nut is loosening, its effect as bought oil, press make hydraulic nut loosening.
5) while installing, suppressing body pressure 150Mpa < piston force is 40 tons, as long as surpass 150Mpa nut, just can become flexible
6) the piston rod 10 joint diameters of this compressor of 6M40-320/0.4-30-BX are minimum, so once the place of piston rod 10 stressed elongations is attaching nut certainly locates.
