Specific embodiment
With reference to the accompanying drawings, in conjunction with one embodiment, a kind of railway carriage sealing device that this utility model is provided is carried out in detail
Thin explanation.
Embodiment
Reference picture 2- Fig. 4, a kind of railway carriage sealing device of the present embodiment, it include bent to press strip 8, transition gripper shoe 7 with
And compensation sealing mechanism, song being fitted on the casing side plate 5 of railway carriage to press strip 8, another side is supported with transition
One side laminating of plate 7, the song are identical with the radius of curvature of transition gripper shoe 7 to press strip 8, and the compensation sealing mechanism is arranged
It is connected to the tail end of press strip 8 and with transition gripper shoe 7 in song.
The compensation sealing mechanism includes compensating press strip 6, duplex limiting plate 13 and baffle plate 1, and the compensation press strip 6 is pressed from both sides
Tightly between baffle plate 1 and duplex limiting plate 13, the side for compensating press strip 6 is fitted on the casing side plate 5 of railway carriage, the compensation
Elongate holes and locating slot is provided with press strip 6.
The baffle plate is provided with block 11, and the block 11 is located at the tail end of compensation sealing mechanism, on the block 11
Disc spring 10 is fixed with, 10 upper end of the disc spring is located in the locating slot.
Two-way guide-localization block 9 is fixed with the baffle plate 1, and the two-way guide-localization block 9 is matched somebody with somebody with elongate holes gap
Conjunction, the two-way guide-localization block 9 and stopper slot interference fit set by duplex limiting plate 13, transition gripper shoe 7, the duplex limit
Position plate 13, two-way guide-localization block 9 are connected by fastening bolt 12, and dismounting and change is simple and convenient, structure reliability.
The song is connected by bolt 4 to press strip 8 with transition gripper shoe 7, and the bolt 4 and song are arranged between press strip 8
There is pressing plate 3.
As shown in figure 1, the straight press strip sealing device of prior art, is fixed by bolt 4 and spring washer component, is clamped in
Baffle plate 1 is fitted with casing side plate 5 with the straight press strip 2 in the middle of pressing plate 3, forms sealing device, and straight press strip is easy with casing side plate
Gap is produced, sealing reliability is poor.
