Detailed description of the invention
For ease of understanding technology contents of the present invention, just by reference to the accompanying drawings its technical scheme is described in further detail below.
A kind of torpedo tank car car coupler knuckle lock locking device as shown in Figures 1 to 8, comprises car coupler knuckle lock 1, matrix 2, jam plate 3 and adjust bar 4.Described car coupler knuckle lock 1 is provided with through hole.Matrix 2 is rigidly attached on torpedo tank car hitch, forms with it one.
As shown in Fig. 3, Fig. 4, Fig. 5, the left part of described matrix 2 is L-type bar, and right part is cuboid, wherein one end of L-type bar and cuboid left side be connected and the recess of L-type bar towards cuboid left side, and making the other end down, L-type bar middle-end upside down part place cylinder forms lock 23.At the parallelepiped body portion of described matrix 2, in lower surface arrange Vertical dimension extend dovetail groove 22 and dovetail groove 22 for large end under, the tapped through hole 21 that Vertical dimension extends is set in upper surface.For ease of assembling, processing, at described tapped through hole 21 two ends, counterbore is set respectively and the aperture of top counterbore is greater than the aperture of bottom counterbore.
The external diameter of described lock 23 is made to coordinate consistent with the through-hole aperture be located on car coupler knuckle lock 1.
As shown in Fig. 3, Fig. 7, Fig. 8, the upper end of described adjust bar 4 is hexagonal prism, it is threaded shank 1 under hexagonal prism, the below of threaded shank 1 is polished rod portion 42, the below in polished rod portion 42 is threaded shank 2 43, described threaded shank 1 is contrary with the thread rotary orientation of described threaded shank 2 43, and described threaded shank 1 external diameter is greater than the external diameter in described polished rod portion 42, and described polished rod portion 42 external diameter is greater than or equal to the external diameter of described threaded shank 2 43.Described adjust bar 4 lower end through the tapped through hole 21 on described matrix 2 and described threaded shank 1 coordinate with the tapped through hole 21 of matrix 2.
As shown in Fig. 3, Fig. 6, the right-hand member of described jam plate 3 be the bucking ladder 32 that extends of Vertical dimension and the small end face of bucking ladder 32 upward, described bucking ladder 32 is coordinated with the dovetail groove 22 on described matrix 2.Vertically extending column type through hole 31 is set in bucking ladder 32 upper surface of described jam plate 3, makes the aperture of described column type through hole 31 be more than or equal to the external diameter in described Guang Defend portion 42.Arrange the through hole of Vertical dimension at the right-hand member of described jam plate 3, this through hole coordinates with described lock 23, and this through hole is preferably set to conical through-hole 33 and holds upper greatly, makes the lower end bore of described conical through-hole 33 consistent with the external diameter of described lock 23.So that use and ensure fiting effect.
As shown in Figure 3, after assembling, on described adjust bar 4, polished rod portion 42 coordinates with column type through hole 31 on jam plate 3, and in described threaded shank 2 43, arranges nut and the upper surface of nut is contacted with the lower surface of jam plate 3.In order to increase the level pressure area of nut to jam plate 3, easily make the upper end described threaded shank 2 43 being arranged nut be provided with annular lip, and the upper surface of annular lip contact with the lower surface of jam plate.
For protecting the L-type bar of matrix 2 can not be subject to outside blastic deformation, benefit is provided with guar plate 5 in the upper end of the L-type bar of described matrix 2.
After assembling, transition axis shoulder grafting between the threaded shank 1 of described adjust bar 4 and polished rod portion 42 touches the upper surface of jam plate 3, be located at nut contact jam plate 3 lower surface in threaded shank 2 43, thus jam plate 3 is just clamped in centre by the transition shaft shoulder and nut, because column type through hole 31 aperture on jam plate 3 is not less than the external diameter in polished rod portion 42, so jam plate 3 can rotate in horizontal surface.It should be noted that, when column type through hole 31 aperture equals the external diameter in polished rod portion 42, then will ensure the processing smoothness requirements of cooperation place inner hole surface and outer cylinder.In use procedure, it is made to move up and down by rotation adjusting lever 4, because the thread rotary orientation of its lower end attaching nut is contrary with the thread rotary orientation of threaded shank 1, so when rotation adjusting lever 4 makes it move up and down, the cooperation of its lower end nut can not be affected and loosen.When adjust bar 4 moves down, it moves down promoting jam plate 3 through hole of its left end (conical through-hole 33) is departed from and the coordinating of lock 23, thus make lock 23 through the through hole on car coupler knuckle lock 1, then contrarotation makes adjust bar 4 drive on jam plate 3 to move, finally make jam plate 3 left end through hole (conical through-hole 33) be sleeved on lock 23.So just, define closed type sealed, make car coupler knuckle lock can not self falling.
Except the technical characteristic described in specification sheets, be the known technology of those skilled in the art.
