Description
Technical field
This application involves railway freight-car steering column structure technologies, and in particular to a kind of portable block key and its side frame.
Background technology
In railway goods train bogie, block key is the anti-drop device of the wheel shaft of cast steel three-piece bogie, practical application
In, block key is mounted on the inside of the side frame guide of bogie by connectors such as bolt, nuts and washers.Railway freight-car is normal
During operation, there are certain gap, block key does not work the bearing of block key and wheel shaft.When lifting or railway freight-car occur to take off
Rail is tumbled when accidents, and block key is contacted with the bearing outer ring of wheel shaft, so as to which wheel shaft be effectively prevent to be detached from bogie.It is existing
Have in technology, cast steel three-piece bogie need to ensure block key and bearing outer ring when assembling block key by adjustment plate thickness
Gap within the scope of rational, whole installing and dismounting is very inconvenient, and it is artificial to take consumption.
Invention content
The purpose of the present invention is to provide a kind of portable block key and its side frame, to overcome deficiency of the prior art.
To achieve the above object, the present invention provides following technical solution：
The embodiment of the present application discloses portable block key and its side frame, and including side frame and block key, the block key passes through spiral shell
Bolt is fixed on side frame, it is characterised in that：The side frame both ends are equipped with the first stud for being symmetrically parallel to block key and second and stand
Muscle, is equipped with inclined surface between first stud and the second stud, the contact surface of the block key and the inclined surface is equipped with cooperation
Inclined-plane, on the block key bolt by bolt hole be slotted hole.
Preferably, in above-mentioned portable block key and its side frame, the inclined surface, the first stud, the second stud and
Side frame is integrally formed.
Preferably, in above-mentioned portable block key and its side frame, the stud base is equipped with split pin.
Preferably, in above-mentioned portable block key and its side frame, the slotted hole both sides are set along inclined surface inclined direction
There is sliding slot, the sliding slot can be with matching and being clamped at the top of bolt.
Compared with prior art, the advantage of the invention is that：Block key and side frame contact surface are set as to the face of constant slope,
One slotted hole and a step be set on block key, and when block key is installed, block key need to only be translated along slotted hole, you can realize block key and
The adjustment in bearing outer ring gap, block key installing and dismounting is simple in structure, and gap is easy to adjust, efficient, at low cost.
Description of the drawings
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or it will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments described in application, for those of ordinary skill in the art, without creative efforts,
It can also be obtained according to these attached drawings other attached drawings.
Fig. 1 show the front view of portable block key and its side frame in the specific embodiment of the invention.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, detailed retouch is carried out to the technical solution in the embodiment of the present invention
It states, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, shall fall within the protection scope of the present invention.
Join shown in Fig. 1, portable block key and its side frame in the present embodiment, including side frame 2 and block key 1, the block key 1
It being fixed on side frame 2 by bolt 3,2 both ends of side frame are equipped with the first stud 4 and the second stud 5 for being symmetrically parallel to block key 1,
Inclined surface 6 is equipped between first stud, 4 and second stud 5, the contact surface of the block key 1 and the inclined surface 6 is equipped with cooperation
Inclined-plane 7, on the block key 1 bolt 3 by bolt hole 8 be slotted hole.
Further, the inclined surface 6, the first stud 4, the second stud 5 and side frame 1 are integrally formed.
In the technical scheme, block key and side frame contact surface are set as to the face of constant slope, a length is set on block key
Circular hole and a step, when block key is installed, block key need to only be translated along slotted hole, you can realize block key and the tune in bearing outer ring gap
Whole, block key installing and dismounting is simple in structure, and gap is easy to adjust, efficient, at low cost.
Further, 8 both sides of slotted hole are equipped with sliding slot 10 along 6 inclined direction of inclined surface, and the sliding slot 10 can be with
Match and be clamped in 3 top of bolt.
Sliding slot directly can reach fixed with the top head of fixing bolt by fastening the nut coordinated with bolt
