Specific implementation mode
Below in conjunction with the accompanying drawings, the following further describes the technical solution of the present invention.
A kind of lock device of fixed bow-backed transport closed-type semitrailer of the present invention is divided into two portions as shown in Figure 1, 2, 3
Point, a kind of guiding fixing device being welded to floor on railway freight-car；One is tire limiting devices, can limit tire
Position and alleviation longitudinal force.
Wherein, guiding fixing device includes：Load-carrying covering 2, lock head device 3, spring 4, spring may be reversed in firm banking 1
Seat 5, fixed pin 6, rotating dog 7, directing plate 8；
Firm banking 1 is welded and fixed with railway freight-car floor.Firm banking 1 passes through fixation with turnable load-carrying covering 2
Pin 6 is connect with rotating dog 7.Wherein, double webs of firm banking are provided with elliptical aperture 11 (as schemed with turnable load-carrying covering both sides
3), rotating dog 7 can the vertical movement in elliptical aperture 11.Turnable load-carrying covering is lifted up again when extracting fixed pin 6, simultaneously
Rotating dog 7, which plays, is laid flat the turning effort of turnable load-carrying covering so that it can be rotated by 90 °.
As shown in figure 4, lock head device 3 includes tapered end 31, lock pillar 32, locking bar 33, bottom fixation circle handle 34, they pass through weldering
Chain link is connected into as an entirety, wherein tapered end 31, lock pillar 32, bottom fix circle handle 34 be realized by the rotation of locking bar 33 it is whole
Rotation, whole rotatable 90 degree；Entire lock head device 3 is combined with spring 4, and lock head device is inserted in spring.
As shown in Fig. 5,6,7, spring base 5 is matched with lock head device 3, and spring base is provided with spring base hole 52 (such as Fig. 7) simultaneously
And lock head device can be inserted in spring base, the cake radius of the bottom fixation circle handle 34 of lock head device is more than spring base hole radius,
Therefore can limited spring seat it is vertical to bottom offset.Spring 4 and spring base top 51 (such as Fig. 6) are rotatable, and can be held with may be reversed
2 inside face layer of shell is carried to be in contact.Slot is opened in 5 side of spring base, and the locking bar 33 of lock head device is stretched out from slot,
Level can rotate 90 degree, to adjust lock head device rotation, to fix semitrailer lock seat hole.Spring base 5 is held with turnable
2 both side plate interior contact of shell is carried, and spring base is equipped with sliding rail 53 (such as Fig. 7), may be reversed in load-carrying covering both side plate
Portion is equipped with the track groove coordinated with sliding rail, and track groove is vertical.It is stayed between the spring base and bottom fix circle handle
There is gap, in order to make lock head device that need not be close to spring base, can make the locking bar of lock head device that rotation be facilitated to be locked, and
Facilitate making and assembling.
Load-carrying covering loading end is equipped with the hole being inserted in for lock head device.
Directing plate 8 is welded with turnable load-carrying covering 2, and guiding semitrailer is integrally put into railway freight-car, and guides tapered end
The locking bar 33 of device is inserted into the lock seat hole of semitrailer.
It is arranged by above structure, when railway freight-car jolts the vertical force of generation, and tapered end locks semitrailer lock
Hole makes entire lock head device move up if vertical force is upward, due to upper layer inside spring and spring base top and load-carrying covering
Face contacts, and lock head device bottom cake limits the downward displacement of spring base, thus can make spring-compressed generate with it is vertical upwards
The reaction force in direction, to have the function that alleviate vertical upward power；If the direction of vertical force is downward, spring is in invisible
Change state, downward power are then decomposed by entire fixing device.
As shown in Figure 8,9, tire limiting device includes：Trapezoidal pedestal 9 guides rounded cap 10, positioning pin 12, flexible handle
13；
For the 9 lower section weldering of trapezoidal pedestal there are two positioning slightly 12, two positioning pin is symmetrical and force-applied uniform.Positioning slightly 12 is inserted
Entering in the hole H (such as Fig. 9) of railway freight-car floor F makes tire limiting device that can be fixed on railway freight-car, and is not needing
When can extract at any time.Wherein, the position of tire limiting device be corresponding first and second tire of semitrailer vehicle extreme direction it
Between.Its Hole has 6 millimeters of tolerance with positioning pin.
Guiding rounded cap 10 is matched with trapezoidal pedestal 9, is welded on the top of trapezoidal pedestal, is reduced to double trailer tyre
Friction injures and plays the role of guiding.
Flexible handle 13 is mounted on trapezoidal pedestal and guiding rounded cap top, for facilitating worker to unload.
Tire limiting device can make tire be fixed on the designated position in railway freight-car, and limit back-and-forth motion, because
And reach and alleviate railway freight-car in transportational process due to longitudinal force caused by brake, so that semitrailer is not produced in railway freight-car
Raw displacement.
As shown in Figure 10,11, guiding fixing device A of the invention is mounted on multimodal transport goods train carriage front end.Wheel
The position of tire limiting device B is between corresponding to semitrailer vehicle first and second tire of extreme direction.
