Embodiment
Embodiment 1:
To Figure 12, the situation that is designed to four joints with integral mechanical structure is an example, describes embodiment of the present utility model in detail in conjunction with Fig. 1, and basic segment joint 3 has only one section, and latter end joint 4 is the 4th section joint.1, second section joint 2 of first section joint, basic segment joint 3, latter end joint 4 adopt the thick walled steel tube manufacturing; The initial end installation shaft bearing apparatus 5 of first section joint 1, turn-screw 7 can freely rotate among being fixed to bearing means 5.Second section joint 2, basic segment joint 3, latter end save 4 initial end interior welds nuts 6, and nut 6 ends are concordant with this section joint end.Each nut 6 can rotate on turn-screw 7 and screw in or screw out.In the same position of 1, second section joint 2 of first section joint, basic segment joint 3 close reinforcement flange 12, open ball by hole 11; Save 4 surface Machining ball orbits 9 at second section joint 2, basic segment joint 3, latter end, the quantity of ball orbit 9 and the ball quantity by hole 11 is identical and arrangement position is corresponding.The ball that ball 8-7 is installed to each Duan Jie is limited in ball between slip limit casing 8-1 and next section joint ball orbit 9 by in the hole 11.First section joint 1 is fixing device, generally is fixed on the bearing table; Second section joint 2 can stretch out in first section joint 1 tube chamber and withdraw; Basic segment joint 3 can stretch out in second section joint 2 tube chamber and withdraw, and latter end saves 4 and can save in basic segment and stretch out in 3 and withdraw.
The situation of Fig. 1 can be considered latter end joint 4 processes of stretching out: the nut 6 of latter end joint 4 constitutes transmission with turn-screw 7; Turn-screw 7 rotates, and promotes latter end joint 4 and stretches out from basic segment joint 3.This moment, basic segment joint 3 nut 6 was in the no silk part 7-1 of turn-screw 7, so basic segment joint 3 can not be driven and stretch out, and 1, second section joint 2 of first section joint also is like this.The slip limit casing 8-1 of basic segment joint 3 is in the position near reinforcement flange 12 at this moment, spring 8-6 is compressed, the trend of the oriented left movement of thrust promotion activity slip limit casing 8-1 of spring 8-6, ball 8-7 is entered before the spacing nest between track 8-2, the pressure slope track 8-4 by be limited in ball orbit 9 and ball tightly, thereby guaranteed that latter end joint 4 saves 3 inner smooth runnings in basic segment, and can not relatively rotate.
Fig. 2 has shown that 4 stretching, extensions of latter end joint put the situation that the limit stoper 8 of basic segment joint 3 comes into force and begins to stretch in place.Latter end joint 4 operation that goes ahead, when the ball 8-7 of basic segment joint 3 runs into the spacing nest 10 of ball on the latter end joint 4, because the pressure effect of slip limit casing 8-1, ball 8-7 can be pressed into the spacing nest 10 of ball, slip limit casing 8-1 ejects under spring 8-6 effect, and ball 8-7 the be pressed in spacing nest 10 of ball and ball tightly entered behind the spacing nest between the track 8-3, this is limit stoper 8 state that comes into force.This moment, latter end joint 4 and basic segment joint 3 were joined together, and became one.When latter end joint 4 moves forward, will drive basic segment joint 3 operation forward together, and the nut 6 of basic segment joint 3 be brought into a part 7-2 that has of turn-screw 7.The nut 6 of the nut 6 of basic segment joint 3 and latter end joint 4 travels forward on turn-screw 7 simultaneously.State as shown in figure 11 during limit stoper 8 spacing coming into force.
Fig. 3 has shown basic segment joint 3 processes of stretching out.The nut 6 of the nut 6 of basic segment joint 3 and latter end joint 4 travels forward on turn-screw 7 simultaneously, and after the segment distance that moves, the nut 6 of latter end joint 4 breaks away from turn-screw 7.The nut 6 of basic segment joint 3 still meshes with turn-screw 7 at this moment, promotes basic segment joint 3 and latter end and saves 4 operations forward together.Basic segment joint 3 stretches out in the process, and the slip limit casing 8-1 of second section joint 2 is limited in the ball orbit 9 of basic segment joint 3 and ball with its ball 8-7 and enters before the spacing nest between the track 8-2, guarantees the smooth running of basic segment joint 3.
Fig. 4 has shown the stretching process of second section joint 2.As above-mentioned situation, during the spacing nest 10 of the ball that runs to basic segment joint 3 as second section joint ball 8-7 of 2, ball 8-7 enters in the spacing nest 10 of ball, slip limit casing 8-1 ejects under spring 8-6 effect, and ball 8-7 the be pressed in spacing nest 10 of ball and ball tightly entered behind the spacing nest between the track 8-3, thereby 3 and second sections joints 2 of basic segment joint are connected as a single entity.Basic segment joint 3 continues to move ahead, and drives the operation forward together of second section joint 2, and the nut 6 of second section joint 2 is brought into a part 7-2 that has of turn-screw 7.
The nut 6 of the nut 6 of second section joint 2 and basic segment joint 3 travels forward on turn-screw 7 simultaneously, and after the segment distance that moves, the nut 6 of basic segment joint 3 breaks away from turn-screw 7.This moment, the nut 6 of second section joint 2 still meshed with turn-screw 7, promoted the operation forward together of second section joint 2 and basic segment joint 3, latter end joint 4.
Fig. 5 has shown that mechanical structure is stretched over the situation of extreme length.The ball orbit 9 of second section joint 2 does not have the spacing nest of ball, and the ball that the ball 8-7 of first section joint 1 is limited in ball orbit 9 and slip limit casing 8-1 all the time enters between the preceding track 8-2 of spacing nest; When second section joint 2 operation that go ahead, when running to ball orbit 9 ends of second section joint 2, second section is saved 2 and can't continue to move forward, and at this time mechanical structure has been stretched over extreme length, has finished the process of stretching out of mechanical structure.
When mechanical structure will be withdrawn, the nut 6 of basic segment joint 3, latter end joint 4 all was in the thick stick state that takes off because the nut 6 of second section joint 2 is with turn-screw 7 engagements, and therefore when turn-screw 7 backward rotation, second section joint 2 will at first be withdrawn first section and be saved 1 inside.
Turn-screw 7 drives second section joint 2 to backhauling row, when running to certain distance, the nut 6 of basic segment joint 3 also meshes with turn-screw 7, two nut motions on turn-screw 7 together, because second section joint 2 do not withdrawn as yet and put in place this moment, the limit stoper of 3 and second sections joints 2 of basic segment joint is not removed as yet, so basic segment joint 3 not withdrawal in second section joint 2 as yet.
As shown in Figure 6, when second section joint 2 continues withdrawal, when its nut 6 advanced to the no silk part 7-1 of turn-screw 7, turn-screw 7 was rotated further, and second section joint 2 no longer continues withdrawal.Turn-screw 7 drives basic segment joint 3 to swivel motion, in this process, first section joint 1 reinforcement flange 12 progressively compressed the spring 8-6 of the limit stoper 8 of second section joint 2, slip limit casing 8-1 leaves the origin-location, progressively close to its reinforcement flange 12, pressure to ball 8-7 is progressively removed, ball 8-7 leaves from the spacing nest 10 of ball, and be limited to ball and enter between the ball orbit 9 of track 8-2 and basic segment joint 3 before the spacing nest, the limit stoper 8 of 3 and second sections joints 2 of basic segment joint is in relieving state, and after this basic segment joint 3 is always to backhauling row.Basic segment saves 3 withdrawal processes as shown in Figure 7.State during limit stoper 8 spacing releasings as shown in figure 12.
The withdrawal of latter end joint 4 is identical with the situation of basic segment joint 3: basic segment joint 3 drives latter end joint 4 to backhauling row, when running to certain distance, the nut 6 of latter end joint 4 screws in turn-screw 7, two nut motions on turn-screw 7 together, arrive the no silk part 7-1 of turn-screws 7 up to the nut 6 of basic segment joint 3, basic segment joint 3 can't continue withdrawal.Turn-screw 7 drives latter end joint 4 to swivel motion, in this process, the ball 8-7 of basic segment joint 3 leaves from the spacing nest 10 of ball of latter end joint 4, and the ball that is compressed to movable slip limit casing 8-1 enters between the ball orbit 9 of track 8-2 and latter end joint 4 before the spacing nest, and latter end joint 4 is automatically terminated with the limit stoper 8 of basic segment joint 3.Latter end joint 4 to backhauling row, runs to short status always under turn-screw 7 drives afterwards.
As shown in Figure 8, when mechanical structure was withdrawn into short status, latter end joint 4 withdrawal basic segments saved 3 inside, second section joint of basic segment joint 3 withdrawals, 2 inside, first section joint of second section joint 2 withdrawal, 1 inside.The nut 6 of second section joint 2, basic segment joint 3 arrives the no silk part 7-1 of turn-screws 7, the nut 6 of latter end joint 4 still with the part 7-2 engagement that has of turn-screw 7.
When mechanical structure needs longer length, can realize by increasing to more multistage joint and limit stoper thereof.During concrete enforcement, first section joint 1 structure is identical in first section joint and the present embodiment, the structure of second section joint 2 is identical in second section joint and the present embodiment, the structure of latter end joint 4 is identical in latter end joint and the present embodiment, the structure of basic segment joint 3 is identical in middle plurality of sections joint and the present embodiment, middle each section joint relative set limit stoper 8.Design segments joint thickness and ball diameter change, and each Duan Jie just in time is coupled; The design turn-screw has silk part and does not have the length of silk part, the status requirement when making it to satisfy nut and screwing in and screw out.
