In the above embodiment, as shown in fig. 2, the first jack 2 is formed on the side wall of the fixing base 1, the lifting hole 3 is formed on the bottom of the fixing base 1 (the bottom of the fixing base 1 is the side of the fixing base 1 facing the bottom of the vehicle body 200), however, the first jack 2 may be formed on the bottom of the fixing base 1, the lifting hole 3 may be formed on the side wall of the fixing base 1, or both the first jack 2 and the lifting hole 3 may be formed on the bottom of the fixing base 1 or on the side wall of the fixing base 1, which is not particularly limited herein. Because need not dismouting first fixed column 4 when dismouting transition piece, consequently, will be used for placing the first jack 2 of first fixed column 4 and offer in fixing base 1's lateral wall, can be after dismantling first mounting bolt 5, the condition that first fixed column 4 is difficult for taking place to drop along the axial of first jack 2. Simultaneously, offer lifting jack 3 in the bottom of fixing base 1, can avoid because the contained angle between lifting jack 3's axis and the axis of first jack 2 is too little to cause the interior local area of fixing base 1 to be equipped with first jack 2 and lifting jack 3 simultaneously, lead to its intensity to weaken the condition.
In the above embodiment, the number of the first insertion holes 2 and the first fixing columns 4 is two, and the two first fixing columns 4 are respectively provided with two first threaded holes 41, and accordingly, each insertion hole is correspondingly communicated with two lifting holes 3, that is, in the lifting assembly 100, two first fixing columns 4 and four first mounting bolts 5 are included, and the mounting strength of the transition piece 300 for fixing the lifting tool through the four first mounting bolts 5 can be ensured, so that the transition piece 300 can be stably fixed with the fixing seat 1, and the situation that the transition piece 300 rotates in the lifting process can be avoided.
Of course, the number of the first fixing posts 4 may be set to three or more and the first fixing posts 4 are respectively provided with three or more first screw holes 41, and the number of the first fixing posts 4 is set to two without being particularly limited herein, and each of the first fixing posts 4 is provided with two first screw holes 41, so that the whole structure and the operation are simplified and more convenient under the condition of ensuring sufficient mounting strength.
In the above embodiment, when the railway vehicle is a train of a motor train unit, the lifting assembly 100 further includes a second fixing post 8 and a second mounting bolt 9, and the fixing base 1 is located above the bogie of the vehicle body 200; the side wall of the fixed seat 1 is also provided with a second jack 6, the bottom of the fixed seat 1 is also provided with a mounting hole 7 communicated with the second jack 6, a second fixing column 8 is positioned in the second jack 6 and is provided with a second threaded hole matched with a second mounting bolt 9, and the second mounting bolt 9 can pass through the mounting hole 7 to be in threaded connection with the second threaded hole and fix the sleeper beam 220 of the vehicle body 200 with the fixed seat 1.
The connection manner between the second fixing post 8 and the second mounting bolt 9 is similar to that between the first fixing post 4 and the first mounting bolt 5, that is, the threaded end of the second mounting bolt 9 can sequentially pass through the sleeper beam 220, the mounting hole 7 and be in threaded connection with the second threaded hole, so as to fix the sleeper beam 220 with the fixing seat 1, and further fix the sleeper beam 220 with the vehicle body 200.
That is, the lifting assembly 100 in this embodiment is applicable to various rail vehicles, including a motor train unit train and a general train, and for the motor train unit train, the lifting assembly 100 of this embodiment can integrate the lifting interface of the vehicle body 200 and the mounting interface of the sleeper beam 220 while ensuring that the space at the bogie is not occupied, simplifying the overall structure and facilitating the mounting operation.
In the above embodiment, the number of the second insertion holes 6 and the second fixing columns 8 is two, and each second fixing column 8 is provided with two second threaded holes, and each corresponding second insertion hole 6 and two mounting holes 7 are communicated, that is, one lifting assembly 100 includes two second fixing columns 8 and four second mounting bolts 9, and the mounting strength can be ensured by fixing the sleeper beam 220 by the four second mounting bolts 9, so that the sleeper beam 220 can be stably fixed with the fixing base 1.
Of course, the number of the second fixing columns 8 may be set to three or more and the second fixing columns 8 are respectively provided with three or more second threaded holes, and the number of the second fixing columns 8 is set to two without specific limitation, and each of the second fixing columns 8 is provided with two second threaded holes, so that the whole structure and the operation are simplified and more convenient under the condition of ensuring sufficient installation strength.
In the above embodiment, the axis of the first jack 2 is perpendicular to the axis of the lifting hole 3, and the axis of the second jack 6 is perpendicular to the axis of the mounting hole 7, so that machining is facilitated.
In the above embodiment, the bottom of the fixing base 1 is provided with the mounting groove 10 for mounting the bolster 220, the mounting groove 10 is provided so as to be aligned with the position of the bolster 220 at the time of mounting, and the side wall of the mounting groove 10 can restrict the movement of the bolster 220 in the longitudinal direction (length direction) of the vehicle body 200.
Further, as shown in fig. 5, a bolster mounting block 11 is further provided between the fixing base 1 and the bolster 220, the bolster mounting block 11 is positioned in the mounting groove 10, and a limit adjustment groove 111 adapted to the bolster 220 is provided at a side of the bolster mounting block 11 facing the bolster 220. At this time, the mounting groove 10 is used to place the bolster mounting block 11. In the installation process, the height and the like of the sleeper beam 220 need to be adjusted, specifically, the specific positions of the sleeper beam 220 can be adjusted by arranging the number of gaskets, the thickness of each gasket and the like between the installation groove 10 and the sleeper beam installation block 11 and between the adjustment limiting groove 111 and the sleeper beam 220, so that the installation accuracy of the sleeper beam is ensured. Of course, in this embodiment, the bolster 220 may be directly mounted in the mounting groove 11 (in this case, there is no bolster mounting block 11), and the specific position of the bolster 220 is adjusted by adding a spacer between the mounting groove 10 and the bolster 220, so that the adjustment range is wider in the two-position adjustment scheme compared with the one-position adjustment scheme, which is advantageous for accurate mounting of the bolster 220.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
