The polish rod strand oscillator direction reverser
Technical field:
The utility model relates to a kind of cable winding device, especially the polish rod strand oscillator reversing arrangement.
Background technology:
Existing polish rod strand oscillator all can only one of them process in take-up or two processes of unwrapping wire play the winding displacement effect, if a reel will successively be finished unwrapping wire and take-up work, existing polish rod strand oscillator is not then realized this function.
Why polish rod strand oscillator can not be used for take-up and two processes of unwrapping wire is simultaneously used, reason is its direction reverser, suppose that the beginning reverse lever is in the left side, this moment, strand oscillator was to left movement, when reverse lever is run into the left limit fixture block, limitation of movement, and this moment strand oscillator still as right motion, reverse lever is by three bearing rotation directions in the reversing shaft drive strand oscillator, strand oscillator continues as right motion until three bearings of strand oscillator the inside forward opposite sense to, thereby make strand oscillator oppositely begin to move right, this moment, reverse lever was put the right side by the left side, and the rest may be inferred when strand oscillator moves right, when reverse lever is run into the spacing fixture block in the right, the strand oscillator commutation, reciprocal back and forth.If but reel becomes the unwrapping wire process by the take-up process suddenly, reel is to counter-rotation, then strand oscillator also begins to the opposite direction motion of original direction, i.e. to the right motion, and this moment reverse lever still in the left side, when strand oscillator moves to the right side and runs into the right limit fixture block, then can not realize like this commutating.
Summary of the invention:
The purpose of this utility model just is for above-mentioned the deficiencies in the prior art, and a kind of polish rod strand oscillator direction reverser is provided.
The purpose of this utility model is achieved through the following technical solutions:

The specific embodiment:
Be described in further detail below in conjunction with drawings and Examples:
The direction reverser of polish rod strand oscillator is that the left end by thread rod 9 is equipped with left limit fixture block 1, and right-hand member is equipped with right limit fixture block 12, and upper reverse lever finishing bevel gear cuter 4 is welded on the reverse lever 10,
Lower reverse lever finishing bevel gear cuter 17 is welded on the lower reverse lever 13, transition gear 5 is installed on the excessive gear stand 6, be equipped with transition gear 5 to fixing rocking handle at excessive gear stand 6, on upper reverse lever 10 and lower reverse lever 13, a roller 11 is housed respectively, roller rotates around S. A. 2, and commutation piece 8 is mounted on the S. A. 2, and spacing card article 7, S. A. 2 and excessive gear stand 6 are installed on the strand oscillator housing, limiting stopper 16 is installed on the lower reverse lever 13, carries out spacing to spring 14.
Left limit fixture block 1, and right limit fixture block 12 is semicircle.Upper reverse lever finishing bevel gear cuter 4 and lower reverse lever finishing bevel gear cuter 17 are connected with transition gear 5.
Increase a reverse lever on original direction reverser, and make up and down two reverse levers realize interlock by three finishing bevel gear cuters, when a reverse lever during on the right side, another reverse lever then is partial to the left side, and two reverse levers are remained in the opposite direction.
Original spacing fixture block is become semicircle, when it rotates to the top, then upper reverse lever is worked, when it rotates to the below, just lower reverse lever is worked.
When the reel take-up, about two spacing fixture blocks to rotate to semicircle downward, by the commutation of lower reverse lever collision fixture block; When the reel unwrapping wire, about two spacing fixture blocks rotate to semicircle upwards, by the commutation of upper reverse lever collision fixture block.
Upper reverse lever 10 and upper reverse lever finishing bevel gear cuter 4 weld togethers, lower reverse lever 13 and lower reverse lever finishing bevel gear cuter 17 also are weld togethers.When upper reverse lever 10 rotates, drive transition gear 5 rotations by upper reverse lever finishing bevel gear cuter 4 like this, transition gear 5 drives again lower reverse lever finishing bevel gear cuter 17 and rotates, thereby lower reverse lever 13 is swung round about.See Fig. 2.
Upper reverse lever 10 and lower reverse lever 13 are realized interlock by upper reverse lever finishing bevel gear cuter 4, transition gear 5, lower reverse lever finishing bevel gear cuter 17, when reverse lever is run into left limit fixture block 1 or right limit fixture block 12, promote swivel block 8 by catch bar 15 and rotate, realize commutation thereby S. A. 2 is rotated.
Why the spacing fixture block in the left and right sides is designed to semi-circular shape, if be because if the spacing fixture block in the left and right sides is designed to circle, then in the process of up and down reverse lever interlock commutation, stuck phenomenon can occur.When reverse lever is run into spacing fixture block and is swung left instantly, the swing of can thereupon turning right of lower reverse lever, a certain both meetings of the moment overlap at straight line in the fixture block position, and then separate round about, if fixture block is circular, then reverse lever can withstand on together on the fixture block and can't rotate up and down, thereby makes commutation failure.And if semicircle, when then going up reverse lever and working, lower reverse lever can be smoothly by semicircle fixture block position.Therefore spacing fixture block must be designed to semicircle.See Fig. 3.
Direction reverser of the present utility model has two kinds of mode of operations: when the reel take-up, about two spacing fixture blocks to rotate to semicircle downward, by the commutation of lower reverse lever collision fixture block; When the reel unwrapping wire, about two spacing fixture blocks rotate to semicircle upwards, by the commutation of upper reverse lever collision fixture block.
One, reel take-up:
During the reel take-up, strand oscillator is along thread rod 9 beginnings to left movement, when reverse lever 13 is run into left limit fixture block 1 instantly, transverse translation is limited, this moment, strand oscillator continued to left movement under reel drives, lower reverse lever 13 relative strand oscillator turning clockwises, turn left by lower reverse lever gear 17 and excessive gear 5 and the upper reverse lever 10 of upper reverse lever gear 4 drives simultaneously, when upper reverse lever 10 forwards the left side to by the right, drive simultaneously the strand oscillator neck bearing reverse, thereby make strand oscillator begin to move right, realize commutation.Strand oscillator continues to move right until run into right limit fixture block 12, commutation, and so forth.
Two reel unwrapping wire:
When reel becomes unwrapping wire by take-up, the reel direction of rotation, strand oscillator moves right along thread rod 9, rotate to semicircle upwards with the spacing fixture block 1 in the left and right sides and 12 this moment, and principle is the same during with the reel take-up, when strand oscillator moves right upper reverse lever 10 and touches right limit fixture block 11, upper reverse lever 10 rotation directions, drive the bearing commutation of strand oscillator the inside, thereby make the strand oscillator commutation, reciprocal successively.
