Problems solved by technology

[0003] This kind of hanging method has certain potential safety hazards. When the bolt breaks, because the equipment has no anti-off protection, it will cause the equipment to fall off and cause a safety accident.
In addition, when the train runs for a long time, due to the impact of vibration, when the bolt connection part undergoes local plastic deformation, the pre-tightening force of the bolt will be insufficient, causing the bolt connection to loosen, and the ability to withstand longitudinal impact is weakened, posing a safety hazard

Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the drawings and specific preferred embodiments.

[0047] Such as Figure 2 to Figure 8 As shown, an underframe equipment suspension support capable of preventing detachment and loosening is hung on the underframe of a rail transit vehicle for installation of underframe equipment 4.

[0048] Such as Figure 4 with Figure 8 As shown, the underframe includes two underframe side beams 1 and a plurality of underframe beams 2, and the underframe beams are all fixed and arranged in parallel between the two underframe side beams.

[0049] A suspension frame 21 is fixedly arranged at the bottom of each underframe beam, and each suspension frame includes a central chute 22, two C-shaped groove cutouts 23 and two C-shaped groove cutouts 24.

[0050] The central chute is arranged at the center line of the suspension frame and is parallel to the underframe beam.

[0051] Two C-shaped groove cuts are arrange...

Abstract

The invention discloses an underframe equipment hanging support capable of preventing falling and looseness as well as a hanging structure. The hanging support is hung on an underframe of a rail transit vehicle and used for mounting of underframe equipment. The hanging support comprises a T-shaped bolt, an underframe mounting surface, two vertical edges, two horizontal turned edges, two vertical plates and an underframe equipment mounting surface. At least one T-shaped bolt mounting hole is formed in the underframe mounting surface; the two vertical edges are symmetrically arranged on two side edges of the underframe mounting surface, one horizontal turned edge is arranged at the top of each of the two vertical edges; each horizontal turned edge, the vertical edge connected with the horizontal turned edge and the underframe mounting surface define a C-shaped groove; the two vertical plates are symmetrically arranged at the bottom of the underframe mounting surface, and a horizontal hook part is arranged at the bottom of each vertical plate; the underframe equipment mounting surface is fixed on the two hook parts horizontally. Underframe equipment falling caused by looseness or breakage of the bolt can be avoided, besides, the shock resistance is high, and bolt looseness can be prevented.

Description

Technical field [0001] The invention relates to an auxiliary structure for rail transit vehicles, in particular to an underframe equipment hanging support and a hanging structure capable of preventing detachment and loosening. Background technique [0002] At present, the following methods are mainly used for hanging the underframe equipment of the existing intercity train: the underframe equipment is directly hung on the lower surface of the underframe beam through bolts and bolt assemblies, such as figure 1 Shown. [0003] This type of hanging method has certain hidden safety hazards. When the bolt is broken, the equipment will fall off due to the lack of anti-falling protection of the equipment and cause a safety accident. In addition, when the train runs for a long time, due to vibration and impact, when the bolt connection part undergoes local plastic deformation, the bolt pre-tightening force will be insufficient, causing the bolt connection to loosen, and the ability to with...
