To achieve the above object, the present invention provides following technical solution：
The embodiment of the present application discloses railway truck bearing anti-drop device and its side frame, it is characterised in that：Including block key and
Side frame, the side frame is interior to be equipped with block key card slot, and the bolt hole coordinated, the block key are equipped with block key end in the block key card slot
It is fixed on by screw bolt and nut in card slot, curved side bearing rod is equipped with along block key pocket edges direction on the side frame, it is described
Block key can be in rotary moving along the arcwall face of side frame stud.
Preferably, in above-mentioned railway truck bearing anti-drop device and its side frame, between the block key and block key card slot
Equipped with limiting plate.
Preferably, in above-mentioned railway truck bearing anti-drop device and its side frame, the block key end is equipped with and bolt
The sliding slot of cooperation.
Preferably, in above-mentioned railway truck bearing anti-drop device and its side frame, the stud base is equipped with split pin.
Preferably, in above-mentioned railway truck bearing anti-drop device and its side frame, the side frame stud and side frame one
Shaping.
Compared with prior art, the advantage of the invention is that：The connection mode of block key and side frame is changed to rotatable knot
Structure only needs to unclamp nut to a certain degree when replacing wheel pair, then block key rotates by a certain angle, can realize wheel pair and side frame
Separation, block key mounting structure is simple, and the take-down time is short, efficient, at low cost.
Description of the drawings
It in order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, below will be to embodiment or existing
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 railway truck bearing anti-drop device and its side frame in the specific embodiment of the invention；
Fig. 2 show railway truck bearing anti-drop device and its postrotational main view of side frame in the specific embodiment of the invention
Figure.
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 on the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
Join shown in Fig. 1, Fig. 2, railway truck bearing anti-drop device and its side frame in the present embodiment, including block key 1 and side
Frame 2, side frame 2 is interior to be equipped with block key card slot 3, the bolt hole 4 coordinated is equipped with 1 end of block key in block key card slot 3, block key 2 passes through spiral shell
Bolt 5 and nut 6 are fixed in card slot 3, and curved side bearing rod 7 is equipped with along 3 edge direction of block key card slot on side frame 2, and block key 1 can be with
It is in rotary moving along the arcwall face of side frame stud 7.
Further, side frame stud 7 and side frame 2 are integrally formed.
In the technical scheme, the connection mode of block key and side frame is changed to rotary structure, is only needed when replacing wheel pair
Nut is unclamped to a certain degree, then block key rotates by a certain angle, can realize separation of the wheel pair with side frame, block key installation knot
Structure is simple, and the take-down time is short, efficient, at low cost.
Join shown in Fig. 1, Fig. 2, further, limiting plate 8 is equipped between block key 1 and block key card slot 3.
Installing limiting plate additional causes the fixation of block key and side frame more to stablize.
Further, 1 end of block key is equipped with the sliding slot 9 coordinated with bolt 5.
Sliding slot can directly can achieve the purpose that fixed block key with the top head of fixing bolt by clamp nut,
The setting of sliding slot facilitates the installation and removal of block key, avoids the difficulty of the fastening bolt in small space.
Join shown in Fig. 1, Fig. 2, further, 5 bottom of bolt is equipped with split pin 10.
In the technical scheme, prevent bolts and nuts from occurring to slide to generate security incident, enhance whole dress well
The security put.
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
