Below operation principle of the present utility model is described in detail:
Again referring to Fig. 1 to Fig. 6:
The utility model is to reequip on existing walking vehicle body, installs one in car body the place ahead and stretches out fixed mount, and an electronic mobile platform is installed on the fixed mount, can be along moving perpendicular to the ground wire direction.The removing nut instrument is installed on the slide block of mobile platform,, unclamps nut by the rotation of a driven by motor one sleeve.Sleeve can be locked on nut automatically.The car body front end is equipped with an automatic clamping mechanism, opens at ordinary times, and when car body was run into stockbridge damper, clamp system clamped stockbridge damper automatically.After nut unclamped, car body can drive stockbridge damper and get back to the bar place.Unclamp clamp system this moment, takes off stockbridge damper.
The scheme of specific embodiment comprises:
1, loose nut body:
Requirement can be aimed at the hex nut on the stockbridge damper automatically, under the effect of mobile platform nut is entangled, and photoelectric sensor is installed on the sleeve, when nut is packaged the rotation of rear motor drive sleeve, unclamps nut under its effect.Mechanism should be taken into account that the nut on the stockbridge damper is in the ground wire left side or on the right side, and therefore whole loose nut body can be changed the direction placement.The motor fixed station is installed on the mobile platform, and after stockbridge damper was clamped, this moment, Hexagonal jacket was in (hole of Hexagonal jacket is bigger than nut slightly, therefore can allow the error in the certain limit) on the same axis with nut basically.Motor is installed on the fixed station, and its output shaft inserts rotation axis inside, and cooperation between the two is bigger matched in clearance, does not therefore need shaft coupling is installed again, and both directly link, and when motor shaft was motionless, rotation axis can rotate among a small circle.On fixed station, because of concentricity requirement is not high, axial force is also little by Bearing Installation for rotation axis, only holds fixing (primary election internal diameter 18, external diameter 40, thick 9 deep groove ball bearing) with a larger axis.The rotation axis front end is a square output, becomes matched in clearance with the square opening of Hexagonal jacket.Therefore, Hexagonal jacket can move along the electrical axis direction.The square take-off lever front end of rotation axis has one to stop screw, prevents that Hexagonal jacket from skidding off.Square take-off lever is equipped with a compression spring outward, withstands Hexagonal jacket.
The photoelectric sensor of one correlation is installed in the both sides of Hexagonal jacket, and under initial situation, both connect by the through hole between the rotation axis.When whole motor fixed station the nut on stockbridge damper under the effect of straight line mobile platform near the time, this moment exist two kinds of situations, the firstth, sleeve has just in time been aimed at nut, thereby directly advances and entangle nut.Another kind of situation is that both stagger, thereby barrel forward end withstood nut, and it can't be advanced.At this moment, under the promotion of thrust, the spring between sleeve and the rotation axis is compressed, and sleeve moves to holder along square pole.Therefore be blocked between emission source and the reception sources, the expression sleeve can't entangle nut.At this moment, electric rotating machine rotates among a small circle, tries to adjust the direction between sleeve and the nut, when both when good, sleeve is pressed forward in the effect of spring force, entangles nut, again conducting between the photoelectric sensor, nut has been entangled in expression, can become flexible task to it.
The distance that mobile platform moves at every turn is the good definite value of a calculating, and when aforesaid first kind of situation occurred, photoelectric sensor was in conducting state always, and loose nut motor directly begins loosening task after mobile platform puts in place.When second kind of situation occurs, be blocked between the photoelectric sensor, the loose nut motor of fine setting makes its conducting again earlier, then begins loose nut.The rotation number of turns of the motor of this moment should be given in advance.
2, clamp system:
After the hold-down nut of stockbridge damper was released, car body was towed back to the bar place with it.Therefore car body need be clamped stockbridge damper, clamps automatically this clamp system should be run into stockbridge damper under spring action after, and should conveniently unclamp after towing back to take out stockbridge damper.
Conventional clamp system all has the special driving device, herein for simple structure and control method, adopts spring as power, and therefore the thrust that is provided is not too large.And should calculate before clamping Hexagonal jacket whether with nut almost coaxial.
Designed the clamp system of dual mode, first kind of scheme be, two clamping plate can rotate around fixed mount, and the place is equipped with torsionspring in center of rotation, makes mechanism have the effect of clamping.Two self-lock rods that link are arranged between two clamping plate, and self-lock rod one side is equipped with a carriage release lever, and carriage release lever can slide along fixed mount.Initial condition is shown in the left figure of Fig. 5, and two self-lock rods are in critical condition, supports two clamping plate it is opened.When whole clamp system travels forward along ground wire, run into stockbridge damper.Self-lock rod is motion backward under the promotion of stockbridge damper, and holding state is destroyed, and as shown at right, this moment, clamping plate were clamped stockbridge damper under spring action, finished the clamping task.After stockbridge damper was pulled, manually carriage release lever opened two flat boards forward, took out stockbridge damper, made mechanism be in self-locking state again.
Second kind of clamp system and first kind are similar, and two clamping plate can rotate around fixed mount, and the place is equipped with torsionspring in center of rotation, makes mechanism have the effect of clamping.Between two clamping plate, be equipped with one and move a piece, can slide along fixed mount.Initial condition moves a piece and is stuck in and makes it can't be closed between two clamping plate shown in the left figure of Fig. 4.When car body travelled forward, whole clamp system travelled forward along ground wire, runs into stockbridge damper.Move piece motion backward under the promotion of stockbridge damper, skid off between two flat boards, this moment, clamping plate were clamped stockbridge damper under spring action, finished the clamping task.After stockbridge damper is pulled, manually open two flat boards, take out stockbridge damper, will move a piece and snap in.
The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection range of the present utility model.
