Abstract
The utility model relates to a micro-adjuster for an eye bolt. The micro-adjuster for an eye bolt is characterized in that the micro-adjuster comprises an eye bolt and an adjusting nut penetrating into a bolt hole of the eye bolt, wherein a circle of grooves are formed at the corresponding parts of the inner wall of the bolt hole of the eye bolt and the outer wall of the adjusting nut, rollers capable of allowing the eye bolt and the adjusting nut to radially and relatively rotate and to be axially positioned backwards and forwards are mounted in the grooves, fabrication holes used for loading the rollers in are formed on the eye bolt, and end plugs are installed on the fabrication holes through screws. The micro-adjuster has the advantages that when micro-adjustment to the axial displacement is performed to the GL-shaped connecting rod during the installation of the railway switch setting system, the normal actions of the structural members for the detection system can be ensured after the back and forth movement of the railway switch setting system, and the rationality and the safety in clearances on both sides of the structural members can be kept by using the micro-adjuster; and both the adjustment accuracy and the operability are high, the accuracy of the indicating circuit for the railway switch setting system is enhanced, the position is kept unchanged after adjustment, and the micro-adjuster plays an important role in eliminating the railway signalling fault.
Description
Technical field
The utility model fastener particularly relates to a kind of slip-knot bolt micro-adjuster of in the railway switch conversion equipment erecting device GL type pipe link being implemented longitudinal travel that is widely used in.
Background technology
At present, in railway switch conversion equipment erecting device, GL type pipe link is implemented the micro-adjustment of longitudinal travel, check system framing member regular event, and keep reasonable, the safety of two side clearances between the framing member, then need the position of running check and adjustment indication notch.And traditional method of adjustment is to unclamp jam nut 17 earlier, as shown in Figure 4, backs off and does not have button axle sleeve 16, and rotation has button axle sleeve 15 to adjust again, screws jam nut 17 after reaching requirement.Above-mentioned method of adjustment is more loaded down with trivial details when operating at the scene, especially after adjust the clearance is good, frictional influence when being subjected to jam nut locking, the adjust the clearance amount is changed, often want repeated multiple times to adjust to the right place, so not only increased labor intensity of operating personnel, and, can't adapt to railway high speed development and heavily stressed reality needs day by day because maintenance time is long.
Summary of the invention
The utility model provides a kind of simple in structure, slip-knot bolt micro-adjuster that adjusting accuracy is high, quick and workable for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: slip-knot bolt micro-adjuster, it is characterized in that: comprise the slip-knot bolt and be installed on the interior setting nut of slip-knot bolt screw, on slip-knot bolt screw inwall and setting nut outer wall corresponding position, have a circle groove, be equipped with in the groove be used for the slip-knot bolt and setting nut radially relatively rotates and axially before and after the roller of location, also be provided with the auxiliary hole of the roller that is used to pack on the described slip-knot bolt, on this hole, plug be housed by screw.
The utility model can also adopt following technical scheme:
Described slip-knot bolt is a ring bodies, and ring bodies top is cast with and its all-in-one-piece tightening latch, and packing ring and hexagon slotted nut are installed on tightening latch.
On the described hexagon slotted nut spring cotter is housed.
One end face of described plug is the arc surface structure.
The shoulder position of described setting nut is equipped with and is used for slip-knot bolt and other parts bonded assembly spring cotter.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, when the installation of railway switch conversion equipment is implemented the micro-adjustment of longitudinal travel to GL type pipe link, after using this slip-knot bolt micro-adjuster can guarantee that the railway switch conversion equipment comes and goes action, its check system framing member regular event, and keep reasonable, the safety of two side clearances between the framing member.This slip-knot bolt micro-adjuster adjusting accuracy height, workable, improved the accuracy of railway switch converting system indication circuit, adjust the position, back and keep inconvenience, therefore offset except that the railway signal fault and have vital function.In addition, the utility model is simple in structure, simple and efficient to handle, and can reduce labor intensity of operating personnel significantly.

The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-Fig. 3, slip-knot bolt micro-adjuster, comprise slip-knot bolt 1 and be installed on the interior setting nut 2 of slip-knot bolt screw, described slip-knot bolt is a ring bodies, be cast with and its all-in-one-piece tightening latch 1-1 on ring bodies top, packing ring 6 and hexagon slotted nut 7 are installed on tightening latch 1-1, on the described hexagon slotted nut 7 spring cotter 10 are housed.On slip-knot bolt screw inwall and setting nut outer wall corresponding position, have a circle groove, several rollers 5 are housed in the groove, by roller 5 slip-knot bolt 1 and setting nut 2 can radially be relatively rotated, and can't move forward and backward and locate on the axial direction.Also be provided with the auxiliary hole of the roller that is used to pack on the described slip-knot bolt, by screw 4 and lock washer with double ears 9 plug 3 be installed on this hole, an end face of plug 3 is an arc surface, and this plug is used to prevent that roller 5 from coming off in the groove drops out.The shoulder position of described setting nut is equipped with and is used for slip-knot bolt and other parts bonded assembly spring cotter 8.
Principle of work of the present utility model is: see also Fig. 5, when the GL type pipe link of track switch conversion equipment is implemented the longitudinal travel micro-adjustment, the track switch conversion equipment links to each other with slip-knot bolt micro-adjuster 12 by H connecting iron 11, and the left and right sides straight line of slip-knot bolt micro-adjuster 12 and the moving tongue of the drag link most advanced and sophisticated sheet iron strip of 14 pullings moves.When switch point housing deviation or indication notch occur when inaccurate, can unclamp jam nut 13, left-right rotation slip-knot bolt micro-adjuster 12 then, and indication notch is accurately finely tuned, and reach to screw jam nut 13 after regulation requires.Installing and using when adjusting with daily attention, adopt this slip-knot bolt micro-adjuster to reduce labor intensity of operating personnel significantly, enhance productivity, and guarantee that original device is intact, ensure railway operation safety.
