Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

As shown in figure 1, the long-span adjustable clamping mechanism for the passenger car frame 6 comprises an end part limiting support 2, a side limiting support 3, an upper limiting pressure plate 4 and an equal-height plate 5. A waist-shaped groove is formed in the base 1, and the end limiting support 2 and the side limiting support 3 are mounted in the waist-shaped groove and can move through bolts.

As shown in fig. 2, 3 and 4, the end limiting bracket 2 and the side limiting bracket 3 have the same structure and comprise L-shaped limiting plates and reinforcing ribs, the end limiting bracket 2 contacts with the front part and the rear part of the frame 6 through cross beams, the side limiting bracket 3 contacts with the middle longitudinal beam of the frame 6 through the middle longitudinal beam, and the cushion pads 7 are detachably arranged on the contact surfaces of the end limiting bracket 2 and the side limiting bracket 3 with the frame 6.
