Embodiment 1

[0033] like Figure 1-4 As shown, the present invention provides a vehicle-mounted suspension carrier, including a carrier body, a side wall connector 6 and a roof connector 7, wherein the carrier body includes a roof for connecting to the roof through the roof connector 7. The surface frame 1, the bottom frame 2 opposite to the top frame 1 and arranged at intervals, and the second side frame 4, the first side frame 3 and the third side frame arranged between the top frame 1 and the bottom frame 2 and connected in sequence 5 (the upper side and the lower side of the second side frame 4, the first side frame 3 and the third side frame 5 can also stretch out the top frame 1 and the bottom frame 2), adopt the structure that the side frames are connected in sequence It is beneficial to save material, so that the side frames of the same size are connected with the top frame 1 and the bottom frame 2 to obtain the largest internal space, wherein the top frame 1, the bottom frame 2 an...

Embodiment 2

[0037] like Figure 5 As shown, because the roof surface is a curved surface, in order to make the connection between the carrier frame and the roof surface more stable, two roof connectors 7 are provided, which are the first roof connector 71' and the second roof connector 71' respectively. The top connector 72', the two roof connectors 7 form a group so that the bottom frame is fixed in the horizontal direction; in this embodiment, the two roof connectors 7 are formed along the top frame 1 and the second side frame 4 or The sides connected to the third side frame 5 are arranged at intervals in the length direction, wherein the standing portion 72 of the first roof connecting body 71 ′ close to the first side frame 3 is relatively far away from the second side of the first side frame 3 . The standing portion 72 of the roof connecting body 72' is relatively short.

Embodiment 3

[0039] like Figure 6-14 As shown, in order to make the side wall connecting body 6 more stable and fixedly connected to the first side frame 3, the end of the horizontal part 61 connected to the first side frame 3 is provided with a connecting plate 63, and the connecting plate 63 is connected by a bolt assembly. It is connected with the first side frame 3 , and the supporting rib 64 is welded between the horizontal portion 61 and the connecting plate 63 . The arrangement of the supporting ribs 64 increases the strength of the side wall connecting body 6 . There are two side wall connectors 6 , and the connecting plates 63 are respectively fixed on opposite sides of the first side frame 3 . The two sides are respectively close to the two adjacent sides of the first side frame, the second side frame and the third side frame.

[0040] Two groups of roof connectors 7 are arranged on the top frame 1 , and the two groups of roof connectors 7 are arranged at intervals along the s...

Abstract

The invention discloses an on-board suspension type bearing bracket. The bearing bracket comprises a bearing bracket body, a train roof connecting body and a side wall connecting body, wherein an object accommodating space with an opened side is defined by a top frame, a bottom frame and at least two side frames in the bearing bracket body; the train roof connecting body comprises a connecting body with two bent ends; the bent position at one end of the connecting body is connected with the top frame, and the bent position at the other end of the connecting body is used for connecting the train roof; and the side wall connecting body is an L-shaped board, one end of the L-shaped board is connected with a side frame, and one side opposite to the end is used for connecting the train side wall. By utilizing the on-board suspension type bearing bracket in the invention, the space use rate in the train can be effectively improved; the bearing bracket fixing position can be selected according to the rest space in the train more flexibly; and since each surface for forming the bearing bracket is the frame, enough openings are reserved for placing the apparatus wiring on the bearing bracket, so as to enhance the convenience of the installing work of an on-board apparatus and enhance the operability of the assembling work of each component.

Description

technical field [0001] The invention relates to the field of design and manufacture of high-speed railway transportation equipment, in particular to a vehicle-mounted suspension carrier frame for fixing and carrying on-board equipment of high-speed EMUs. Background technique [0002] The rational layout of the on-board equipment of the ATP (Automatic Train Protection) system of high-speed EMUs is the best way to improve the availability, maintainability and reliability of the equipment, and it is a powerful measure to ensure the safety of the train. The existing train ATP system on-board equipment is usually fixed on the floor of the vehicle equipment cabinet in the form of bolt connection; this kind of connection structure is a two-dimensional plane layout, which has the following defects: it reduces the utilization rate of the internal space of the train; it leads to the flexibility of the combination layout of the ATP on-board equipment The performance is poor, which is n...
