The snap ring 66 passes through the groove on 65 head of positioning screw.
Grading ring is made of semi-ring A and semi-ring B, is bolted before two semi-rings.
The fixation of semi-ring A is carried out first, and specific step is:
1. postposition base body is installed on insulating bar, also have on insulating bar similar to 32 sample of postposition base body upper junction plate 31 and elongated slot Structure, the connecting plate 31 on postposition base body is inserted on insulating bar;
2. the head of two bolts is placed individually into Hexagon hole 24, then semi-ring A is put on tablet 11, and adjusts it With the relative position of backboard 12, two mounting holes that two bolts is made to be each passed through on semi-ring A adjust itself and backboard 12 again Relative position, the middle part that Positioning arc plate 13 is made to be located at semi-ring A;
3. pulling location hook 42 simultaneously and lower location hook 46 rotating, semi-ring A is made to be bonded with Positioning arc plate 13, unclamp lower location hook 46, lower adjustment spring 47 drives cross bar 45 to rotate, and lower location hook 46 is rotated with cross bar 45, and semi-ring A is caught on;It then will be upper fixed Position hook 42 unclamps, and upper adjustment spring 44 promotes adjusting screw rod 43, rotates location hook 42, semi-ring A is caught on;
4. loose nut 34, and plate 31 is rotatablely connected, bumper bar 35 is made to be attached on a side of semi-ring A, then counter-tightened Nut 34;Pretightning force between adjusting nut 34 and circle set 14 simultaneously makes applying one to after to big thrust therebetween It can relatively rotate, avoid because resistance is excessive postposition base body being caused with grading ring latter half can not to divide during separated From.
Then the fixation of semi-ring B is carried out, specific step is:
1. preposition base body is installed on another insulating bar, the step is identical with the installation steps of postposition base body, herein not It is repeating;
2. semi-ring B is placed between prelocalization arc plate 58 and auxiliary positioning arc plate 59, and before promoting pressure pin 52 along preceding base body 51 axis directions move backward, and when moving, locating ring 53 drives front hook 57 to rotate, and semi-ring B is pressed in auxiliary positioning arc plate On 59.
The insulating bar of two installation nuts is then ready for, specific step is:
1. nut is placed into Hexagon hole A63, body 61 is installed on insulating bar, the step is identical with above-mentioned steps, Details are not described herein again;
2. rotational positioning screw 65 makes the screw rod of positioning screw 65 be contacted with the outer wall of nut, prevent nut from Hexagon hole A63 It comes off;
It 3. snap ring 66 is strutted, and is placed into the groove on 65 head of positioning screw, the effect of snap ring 66 is prevented in body 61 The loosening of positioning screw 65 causes nut to be slid from Hexagon hole A63 during rotation.
Preparation is completed, and proceeds by installment work, specific step is:
1. first job personnel hold the insulating bar for being equipped with postposition base body, postposition base body is moved to grading ring mounting rod Rear;
2. second staff holds the insulating bar for being equipped with preposition base body, preposition base body is moved to grading ring mounting rod Front;
, to preceding promotion, 3. screw rod will be made to pass through the installation of semi-ring B after the screw rod on the location hole alignment postposition base body on semi-ring B Hole;
4. the insulating bar in hand is sent in the hand of second staff by first staff, picks up one and be fixed with tightly Admittedly the nut being placed in Hexagon hole A63 is screwed to the screw rod for being aligned and being placed on postposition base body by the insulating bar of nut apparatus It goes up and tightens;
5. replacing another insulating bar for being equipped with tight nut apparatus, the operation in step 4 is repeated, nut is screwed to another On screw rod and tighten;
6. reversely dropping the insulating bar for being equipped with preposition base body, pressure pin 52 is pressed along preceding 51 axis direction case of base body is separate before making The direction movement of ring, the locating ring 53 on preceding pressure pin 52 move, stir front hook 57 and rotate simultaneously, away from semi-ring B, then Insulating bar is moved down, semi-ring B is made to leave prelocalization arc plate 58 and auxiliary positioning arc plate 59, thereby realizes preposition base body Separation;Connecting plate 54 slides in link slot 55, the relative rotation of base body 51 and preceding pressure pin 52 before can avoiding;
7. firmly promoting postposition base body backward by insulating bar, upper location hook 42 and lower location hook 46 leave semi-ring A, thus real The separation of postposition base body is showed.
After preposition base body and postposition base body are separated with grading ring, whole installment works is completed.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations, although The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that, still may be used To modify to the technical solution recorded in previous embodiment or carry out equivalent substitution to which part technical characteristic, and These modifications are replaced, and the essence of appropriate technical solution is not made to depart from the spirit and model of technical solution of the embodiment of the present invention It encloses.
