The utility model provides a technical scheme as follows of its technical problem:
the utility model provides an under-vehicle equipment cable suspension device for striding a formula monorail vehicle, connects between waiting to adorn equipment and automobile body chassis crossbeam, includes and hangs seat, vertical roof beam and cross the cab apron, cable suspension device through welded connection in on the automobile body chassis crossbeam, wait to adorn equipment through detachable mode fastening connection in hang the seat.
The utility model discloses further perfect scheme as follows:
furthermore, the hanging seats are connected to the middle of the longitudinal beam in a welded mode, the transition plates are connected to the two ends of the longitudinal beam in a welded mode, and the hanging devices are connected to the cross beam of the underframe of the vehicle body through the transition plates in a welded mode.
Further, hang the seat by strengthening curb plate and L type body and constitute, strengthen the curb plate have two, respectively welded connection in the long limit dorsal part of L type body, hang still be equipped with on the seat with wait to adorn the through-hole that the equipment is connected.
Further, the longitudinal beam is of a hollow square tube structure.
Further, the transition plate is an irregular U-shaped plate.
Further, the longitudinal beam is located in the U-shaped groove of the transition plate.
Further, the hanging seat, the longitudinal beam and the transition plate are all made of Q345B plates.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses solution that can be fine is present strides a formula monorail vehicle car and is equipped with cable suspension device and be difficult to the welding, and the welding seam shaping is poor, the abominable defect of mechanical properties. The structure is more suitable for mass production, and can ensure the long-term safe operation of the vehicle.

Description of reference numerals: 1. a hanging seat; 2. a longitudinal beam; 3. a transition plate; 4. a vehicle body underframe cross beam.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the under-vehicle equipment hanging device for the straddle-type monorail vehicle is connected between equipment to be installed and a vehicle body underframe cross beam 4 and comprises a hanging seat 1, a longitudinal beam 2 and a transition plate 3, the hanging device is connected to the vehicle body underframe cross beam 4 through welding, and the equipment to be installed is fastened and connected to the hanging seat 1 in a detachable mode.
The hanging seat 1 is connected to the middle of the longitudinal beam 2 in a welded mode, the transition plates 3 are connected to the two ends of the longitudinal beam 2 in a welded mode, and the hanging device is connected to the vehicle body underframe beam 4 in a welded mode through the transition plates 3.
Hang seat 1 and constitute by strengthening curb plate and L type body, it has two to strengthen the curb plate, respectively welded connection in the long limit dorsal part of L type body, hang and still be equipped with on the seat 1 with wait to adorn the through-hole that the equipment is connected.
The longitudinal beam 2 is of a hollow square tube structure. The transition plate 3 is an irregular U-shaped plate. The longitudinal beam 2 is positioned in the U-shaped groove of the transition plate 3.
The hanging seat 1, the longitudinal beam 2 and the transition plate 3 are all made of Q345B plates.
A car equipment cable suspension device for striding a formula monorail vehicle under, be the key structure that chassis main structure and vehicle equipment are connected, connect between chassis crossbeam and equipment, play fixed equipment's effect. The structure is connected with the cross beam of the bottom frame through four welding seams and is connected with equipment through the hanging seat.
The single hanging seat 1 in the utility model is formed by welding two reinforced side plates and an L-shaped body, and the material is Q345B; the longitudinal beam 2 is of a hollow square tube structure and made of Q345B, and plays a role in supporting the whole system in the whole equipment hanging device; the transition plate 3 is of a U-shaped bending structure, plays a role in transferring load, dispersing stress concentration and improving fatigue performance, and is made of Q345B.
