Abstract
The utility model discloses an urban rail vehicle chassis pipe installation structure which comprises main transverse beams. Pipe holes are formed in the main transverse beams and matched with pipes of an urban rail vehicle, bent plates are arranged at the positions of the upper walls of the main transverse beams, the cross sections of the bent plates are in L types, vertical plates of the bent plates are connected to the edges of the upper walls of the main transverse beams, bolt holes are formed in transverse plates of the bent plates, the transverse plates are not lower than the uppermost edges of the pipe holes, the pipes penetrate through the pipe holes to be clamped through pipe clamps, and the pipe clamps are fastened to the transverse plates of the bent plates through bolts. The urban rail vehicle chassis pipe installation structure is reasonable in structural layout, concise and practical in installation mode and suitable for design use of an urban rail vehicle chassis, the labor intensity is reduced, and the production rate is improved.
Description
Technical field
The utility model relates to body for mass transit vehicles technical field of structures.
Background technology
The vehicle body bottom frame of city rail vehicle is as the carrying basis of whole car body, the weight of not only bearing car body itself, but also various electrical equipment, brake equipment under carrying vehicle, the weight of the interior all devices of electrical pipeline, brake piping and car.Therefore need underframe to have certain strength and stiffness.In addition, under car, equipment Pipe-Line need be connected with underframe rationally, firmly, so when guaranteeing underframe strength and stiffness, it is particularly important that Undercarriage structure rational deployment also seems.In city rail vehicle, vehicle body bottom frame generally adopts modular design at present, and bottom frame forms, the compositions such as side bar composition, main beam, as shown in Figure 1.Prior art scheme main beam adopts channel-section steel structure, and athwartship plane is opened slotted hole, is used for arranging braking, electrical pipeline, as shown in Figure 2.This kind of structure, for the fixedly more complicated of brake piping, electrical pipeline, need be welded flap seat on main beam, by pipe clamp and bolt, pipeline is fixed on flap seat, and as shown in Figure 3, this kind of structure mainly contains following shortcoming: 1 layout is not attractive in appearance; 2 complicated operations, increase work capacity; 3 weld flap seat on main beam easily produces welding deformation.
Utility model content
It is more convenient, succinct that the technical matters that the utility model solves is to provide a kind of mounting means of braking, electrical pipeline that makes, the city rail vehicle mounting structure for pipeline of underframe that under car, layout is more reasonable, attractive in appearance.
The technical solution adopted in the utility model is a kind of city rail vehicle mounting structure for pipeline of underframe, comprise main beam, on main beam, offer pipeline hole, the pipeline of pipeline hole and city rail vehicle is suitable, and main beam upper wall place is provided with bending plate, bending plate cross-sectional plane is L-type, the riser of bending plate is connected in main beam upper wall edge, on the transverse slat of bending plate, offers bolt hole, and the height of transverse slat is not less than pipeline Kongzui upper limb, pipeline blocks with pipe clamp through pipeline hole, and pipe clamp uses bolted in the transverse slat of bending plate.
The beneficial effects of the utility model are that (1) pipeline mounting means is succinctly practical, reduces welding job amount, reduces labour intensity, boosts productivity; (2) make car lower pipeline layout more reasonable, attractive in appearance; (3) than channel-section steel structure in the past, this kind of structure can improve underframe intensity.
Accompanying drawing explanation
Fig. 1 is prior art vehicle body bottom frame structural representation.
Fig. 2 is main beam constructional drawing in prior art.
Fig. 3 is mounting structure for pipeline of underframe schematic diagram in prior art.
Fig. 4 is main beam constructional drawing in the utility model.
Fig. 5 is the utility model mounting structure for pipeline of underframe schematic diagram.
In figure, be labeled as: 1-one end underframe, 2-bis-bottom framves, 3-side bar, 4-main beam, 41-pipeline hole, 5-flap seat, 6-pipe clamp, 7-pipeline, 8-bending plate, 81-bolt mounting holes.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 4, Figure 5, former main beam 4 cross sections one-tenth openings are U-shaped towards inner side, on former main beam 4 bases, increase a bending plate 8, bending plate 8 cross-sectional planes are L-type, and the riser top of L-type is connected with main beam 4 upper wall edge, on the transverse slat of bending plate 8, offer bolt mounting holes 81, the height of transverse slat 8 will, higher than the height in pipeline hole 41, in order to avoid affect passing through of pipeline, also can not exceed too many, be inconvenient to fix, preferably make the upper limb in transverse slat 8 and pipeline hole 41 keep concordant.Brake piping and electrical pipeline are fixed on underframe, through the line portals 41 on main beam 4, utilize a pipe clamp 7 and bolt pipeline can be fixed on to bending plate 8 transverse slat places, bolt mounting holes 81 adopts slotted hole, and leave in the longitudinal direction fitting allowance, be convenient to pipeline and install.
Claims (2)
1. city rail vehicle mounting structure for pipeline of underframe, comprise main beam, on main beam, offer pipeline hole, the pipeline of pipeline hole and city rail vehicle is suitable, it is characterized in that: described main beam upper wall place is provided with bending plate, bending plate cross-sectional plane is L-type, the riser of bending plate is connected in main beam upper wall edge, on the transverse slat of bending plate, offers bolt hole, and the height of transverse slat is not less than pipeline Kongzui upper limb, pipeline blocks with pipe clamp through pipeline hole, and pipe clamp uses bolted in the transverse slat of bending plate.
