It is low, it is of high cost.
Utility model content
The purpose of this utility model is to provide a kind of railway truck bearing anti-drop device and its side frames, to overcome existing skill
Deficiency in art.
To achieve the above object, the utility model provides the following technical solutions：
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 block key card slot is interior and block key end is equipped with the bolt hole coordinated, the block key
It is fixed in card slot by screw bolt and nut, side frame upper edge block key pocket edges direction is equipped with curved side bearing rod, described
Block key can be along the arcwall face moving in rotation 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
Molding.
Compared with prior art, the utility model has the advantage of：The connection type of block key and side frame is changed to revolve
Rotation structure, replace wheel clock synchronization only need by nut unclamp to a certain degree, then block key is rotated by a certain angle, can realize wheel pair with
The separation of side frame, block key mounting structure is simple, and the take-down time is short, 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 railway truck bearing anti-drop device and its side frame in the utility model specific embodiment；
Fig. 2 show railway truck bearing anti-drop device and its postrotational master of side frame in the utility model specific embodiment
View.
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, Fig. 2, the railway truck bearing anti-drop device in the present embodiment and its side frame, including block key 1 and side
Frame 2, side frame 2 is interior to be equipped with block key card slot 3, and block key card slot 3 is interior and 1 end of block key is equipped with the bolt hole 4 coordinated, and block key 2 passes through spiral shell
Bolt 5 and nut 6 are fixed in card slot 3, and 2 upper edge block key card slot of side frame, 3 edge direction is equipped with curved side bearing rod 7, and block key 1 can be with
Along the arcwall face moving in rotation of side frame stud 7.
Further, side frame stud 7 and side frame 2 are integrally formed.
In the technical scheme, the connection type of block key and side frame is changed to rotary structure, replacing wheel clock synchronization only needs
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 makes the fixation of block key and side frame more 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 fastening 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, 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
