Description
Technical field
The invention belongs to railway transport field, and in particular to the anti-loose mounting structure of motor train unit bogie skirtboard.
Background technology
With the lifting of EMUs speed, influence of the air drag to EMUs is increasing.Lower turn of motor train unit
Need to install bogie skirtboard additional to frame both sides and carry out drag reduction.
Existing EMU apron board mounting structure is that fixed support is set below vehicle body bottom frame, is pacified on bogie skirtboard
Dress apron board lock, fixed bogie skirtboard is installed by apron board lock, and its scheme that is connected substantially is threaded connection.In practice
In frequent following problem：(1) easily there is thread looseness in apron board lock；(2) easily there is vibrations noise in bogie skirtboard；（3）Bogie
The position that skirtboard installs apron board lock is often damaged；(4) long-term with such as overhauling not in place, there is case accident in skirtboard, exists very
Big potential safety hazard.
Therefore, it is the security of raising motor train unit bogie skirtboard, is badly in need of a kind of new bogie skirtboard of research and company is installed
Binding structure is released preventing bogie skirtboard, it is ensured that the safety operating of EMU.
The content of the invention
It is an object of the invention to provide the bogie apron board mounting structure that has anti-loose function.
To achieve the above object, the present invention provides a kind of Highs-speed motor train unit bogie apron board mounting structure, it is characterised in that：
Including bogie skirtboard, fixed support, anti-rotation sliding block, fastening bolt, stop nut, safety pin, 4 are set on the bogie skirtboard
Individual block set, the fixed support sets 4 steady pins, and 4 block sets of bogie skirtboard and support bracket fastened 4 steady pin grafting are pacified
Dress, the bogie skirtboard medial surface sets chute, anti-rotation sliding block is provided with chute, and fastening bolt is placed in anti-rotation sliding block, and is worn
Fixed support is crossed bogie skirtboard and fixed support tighten together by stop nut and safety pin, one stabilization of composition
Anti-loose structure.
Nylon jacket is set between the block set and steady pin.
Advantages and positive effects of the present invention：
（1）The present invention devises a novel plugging and installs position limiting structure, and bogie skirtboard is used with support bracket fastened fastening point
Stop nut and safety pin combination are locking, it is ensured that bogie skirtboard is not released.Improve the security of bogie skirtboard.
（2）The present invention sets nylon jacket between block set and steady pin, it is therefore an objective to which the two is produced to prevent rainwater and cleaning fluid from invading bubble
Raw couple corrosion, increases service life, while being avoided that the two collides, reduces the motion artifacts of bogie skirtboard.
（3）The present invention sets chute in bogie skirtboard medial surface, and exposed face keeps smooth, improves bogie skirtboard outward appearance
Visual effect and air drag-reduction effect.

4 block sets of plate and support bracket fastened 4 steady pin grafting are installed, and the bogie skirtboard medial surface sets chute 7, set in chute
There is anti-rotation sliding block 9, fastening bolt 8 is placed in anti-rotation sliding block 9, and pass through stop nut 11 and safety pin 12 through fixed support 2
Bogie skirtboard and fixed support are tightened together, an anti-loose structure for stabilization is constituted.
Refering to Fig. 3, Fig. 4, the lower section of the vehicle body bottom frame side bar 1 sets fixed support 2, and steady pin 6 is set on fixed support 2.
Refering to Fig. 5, Fig. 6, the bogie skirtboard 3 sets block set 5 and medial surface sets chute 7.
Refering to Fig. 7, the grafting of steady pin 6 of the block set 5 and fixed support 2 of the bogie skirtboard 3 is installed, the block set 5
Nylon jacket 4 is set and steady pin 6 between.
Refering to Fig. 8, the dress is to frame skirtboard 3 by chute 7, fastening bolt 8, anti-rotation sliding block 9, adjust pad 10, locking
Nut 11, safety pin 12 will be filled and be fixed together to frame skirtboard 3 and fixed support 2.
