Apron board limiting device of under-vehicle equipment compartment

Abstract

The invention discloses an apron board limiting device of an under-vehicle equipment compartment. The apron board limiting device comprises an apron board and a framework lower edge beam; a first hookis arranged at the lower part of the apron board; a second hook matched with the first hook is arranged at the lower part of the framework lower edge beam; the apron board and the framework lower edge beam are connected through the first hook and the second hook; and a limiting block for limiting the apron board to move in the direction perpendicular to the longitudinal section of the apron boardis arranged at the lower part of the framework lower edge beam. The apron board limiting device has the beneficial effects that 1, all-angle limiting is realized, and specifically limiting of the apron board can be realized in the whole apron board opening angle range; 2, the apron board is convenient to mount and dismount, and specifically the apron board can be mounted and dismounted under thecondition that the limiting block is not dismounted; 3, the structure is stable, and specifically the apron board limiting device is high in strength and not prone to deformation; and 4, the apron board limiting device is convenient to maintain, and specifically the limiting block adopts the detachable structure, and later maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of an under-vehicle equipment compartment of a rail vehicle, in particular to a skirt limiting device for an under-vehicle equipment compartment. Background technique [0002] At present, the lower part of the apron in the Chinese standard EMU with a speed of 250 kilometers per hour is connected to the lower side beam of the skeleton through a hook, and the upper part is fastened by cooperating with the upper side beam of the skeleton through the apron lock. However, the apron in the prior art cannot effectively realize the position limitation of the apron, and cannot ensure that the apron lock is aligned with the lock hole, so that the force state of the apron lock is relatively poor. [0003] Therefore, how to provide a skirt plate limiting device that can effectively realize the skirt plate limit, ensure that the skirt plate lock is centered with the lock hole, and make the skirt plate lock in a good stre...
