Embodiment
This railway contact line plough sour jujube pad snap close locking device is made up of kingbolt 1, mother nut 2, locking nut 3 and plough ratchet pad 4, kingbolt 1 is manufactured with main thread 5 and checknut 6, the external diameter of checknut 6 is slightly less than the internal diameter of main thread 5, the locking section be convenient to when mother nut is installed easily from kingbolt is passed through, after mother nut is in place, put into plough ratchet pad 4; Main thread 5 is equipped with mother nut 2, checknut 6 is equipped with locking nut 3, plough ratchet pad 4 is housed between mother nut 2 and locking nut 3.(see accompanying drawing 1).
Main thread 5 on described kingbolt 1 is coarse thread right-hand thread with mother nut 2, and checknut 6 and locking nut 3 are closely-pitched left hand thread.
It is the plough ratchet 7 that man type is separated to both sides that the two sides of described plough ratchet pad 4 is all manufactured with land, plough ratchet 7 is circumferentially being uniformly distributed, the summit of plough ratchet 7 is in plough ratchet pad 4 on circle, on the inner circle that the herringbone sword on both sides ends at plough ratchet pad 4 respectively and cylindrical, the line of the terminating point of herringbone sword in inner circle and cylindrical overlaps with the diameter at the ratchet summit place of adjacent plough ratchet 7.(see accompanying drawing 2 ~ 4).
The height difference L of the terminating point on the summit of the plough ratchet 7 of described plough ratchet pad 4 and herringbone sword and inner circle and cylindrical is 0.5 ~ 2 millimeter.(see accompanying drawing 5).
Working principle and the using process of this railway contact line plough sour jujube pad snap close locking device are:
The plough ratchet pad 4 of this railway contact line plough sour jujube pad snap close locking device has special structure, and it is made by the steel that can harden, and the ratchet size, direction, shape, layout etc. of two EDS maps are identical.The relief angle of plough ratchet 7 is mild, slips over gently when being convenient to locking nut counter-tightened; Anterior angle is vertically precipitous, forms sour jujube point and land, is just meeting and unclamp direction facing to nut after installation, stop nut loosening.The office of this portion of plough ratchet 7, similar plough point and both sides sword, its objective is to be cut into greatest extent in the end face of mother nut 2 and locking nut 3 when plough ratchet 7 works.Simultaneously this kind of structure also improves the strength and stiffness of plough ratchet pad 4, and makes each plough ratchet 7 stressed even as far as possible.Plough ratchet pad 4 can machining or drawing, but punch die precision wants high, to ensure that crown and man type both sides sword keep sharp.Must harden after shaping HRc >=45, hard crown and both sides sword are pressed into soft nut end face certain depth after screwed tight, increase the soundness be connected with nut, to guarantee device operationally never becoming loose.(see accompanying drawing 3 ~ 5).
The mother nut 2 of this railway contact line plough sour jujube pad snap close locking device and the spiral shell footpath of locking nut 3, pitch are different, and rotation direction is contrary.The locking section of kingbolt 1 is manufactured with reverse closely-pitched left hand thread, because fine thread can bear larger torsion than the coarse thread in same footpath, there is larger axial tension, also not easily loosen, be used in locking section very favourable.When mother nut 2, plough ratchet pad 4, locking nut 3 three elements combinations are installed together synergy formation snap close relation, can ensure that this railway contact line plough sour jujube pad snap close locking device can never loosen completely.
When this railway contact line uses with plough sour jujube pad snap close locking device, mother nut 2 and locking nut 3 form " locking " relation jointly by plough ratchet pad 4 after tightening separately, namely the retrogressing rotation direction of mother nut 2 is just the advance rotation direction of locking nut 3, and after two nuts tighten respectively, the crown on plough ratchet pad 4 two sides and land are all met and are unclamped direction facing to two nuts.Oppositely loosening, even if no exception when judder when locking nut 3 definitely prevents mother nut 2 to work.When disassembly is desired, because spanner rotates forward force by force to locking nut 3, when this power reaches certain large, plough ratchet pad 4 has had small elastic deformation, and locking nut starts to retreat, so the power of supporting of plough ratchet 7 reduces, spanner continues force, locking nut 3 retreats more, then continues, and locking nut 3 has just unclamped; This release process is for artificially to turn with spanner brute force, but in no way this situation generation in its natural state during work, namely this railway contact line plough sour jujube pad snap close locking device can not unlock naturally, is therefore in use to be perfectly safe reliably.
In addition, mother nut 2 and locking nut 3 tighten up the rear axial tension all producing equidirectional on kingbolt 1, therefore the actual pulling force acted on kingbolt 1 is the compound of two kinds of nut effects, mother nut 2 so just can be made to design thinner, and locking nut 3 has been locking braking action, that can design is thinner, and thus, what this railway contact line plough sour jujube pad snap close locking device can be made to make is as far as possible light and handy.
