Abstract
This application discloses a kind of portable block key and its side frames, including side frame and block key, the block key is bolted on side frame, the side frame both ends are equipped with the first stud and the second stud for being symmetrically parallel to block key, inclined surface is equipped between first stud and the second stud, the block key and the contact surface of the inclined surface are equipped with the inclined-plane of cooperation, on the block key bolt by bolt hole be slotted hole.It sets block key and side frame contact surface in the face of constant slope, a slotted hole and a step is set on block key, and when block key is installed, block key need to only be translated along slotted hole, you can realize the adjustment in block key and bearing outer ring gap.Block key installing and dismounting is simple in structure, and gap is easy to adjust, efficient, at low cost.
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
When 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
When rail, the accidents such as tumble, block key is contacted with the bearing outer ring of wheel shaft, to effectively prevent wheel shaft 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.
Utility model content
The purpose of this utility model is to provide a kind of portable block key and its side frame, with overcome it is in the prior art not
Foot.
To achieve the above object, the utility model provides the following technical solutions：
The embodiment of the present application discloses portable block key and its side frame, including side frame and block key, and 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 are sliding slot, the sliding slot that can match and be clamped at the top of bolt.
Compared with prior art, the utility model has the advantage of：Set block key and side frame contact surface to constant slope
Face, a slotted hole and a step be set on block key, and when block key is installed, block key need to only translate along slotted hole, you can realization
The adjustment in block key and 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 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,
Other drawings may also be obtained based on these drawings.
Fig. 1 show the front view of portable block key and its side frame in the utility model specific embodiment.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Detailed description, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Join shown in Fig. 1, the portable block key in the present embodiment and its side frame, 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 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 the 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
The purpose of block key, the setting of sliding slot facilitate the installation and removal of block key, avoid the difficulty of the fastening bolt in small space.
Join shown in Fig. 1, further, 3 bottom of bolt is equipped with split pin 9.
In the technical scheme, it prevents bolts and nuts from sliding occurs and generates safety accident, enhance whole dress well
The safety set.
It should be noted that herein, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation
