Description

Technical Field

[0001] The utility model relates to the technical field of rail vehicle assembly components, in particular to an underframe side beam suspension structure. Background Art

[0002] The chassis side beams are components set on both sides of the bottom of the rail vehicle to strengthen the strength of the vehicle body. They can also be used as hanging and fixing points for under-vehicle equipment. Conventionally, when equipment needs to be hung, connecting plates are usually welded to the chassis side beams, and then the equipment and the connecting plates are welded or bolted to form a fix. This method requires that the position of the equipment and the chassis side beams be compared before installation. It is believed that deviations in the fixed positions of the connecting plates and the side beams are likely to occur during the comparison process, which can easily cause the connection points to deviate when the equipment and the connecting plates are subsequently connected. This makes the connection plate aligned with the part of the equipment that is difficult to connect, which in turn will lead to the need to cut and rework the connecting plate for repositioning and welding.

[0003] In view of this, a design or technical improvement is now proposed to solve the above problems.

[0004] The above content is only used to assist in understanding the technical solution of the present invention and does not mean that the above content is the closest prior art. Utility Model Content

After the support arm 53 is slid and adjusted, the second bolt 64 can be rotated to make it move upward, and then cooperate with the connecting plate 26 to clamp and support the equipment. To ensure that the support arm 53 does not slide, the third bolt 73 can be rotated to support the positioning plate 71 to extend from the seventh limiting slot 7, and then cooperate with the card slot 72 at its upper end to lock the support arm 53.
