Abstract
The utility model provides a connecting seat for circular steel tube cross beams of a framework. A through hole is formed in the middle of the baseplate of the main body part of the connecting seat and is connected with a through hole on a circular lug boss into a whole body and the two through holes are coaxial; both the diameters of the through holes are smaller than that of a cross beam; a transitional round corner with a diameter ranging from 25 to 30 is formed between the outer peripheral surface of the circular lug boss and the baseplate; a round tube-shaped positioning table is arranged in the through hole of the main body part of the connecting seat; and one part of the positioning table is fixed in the through hole at the main body part of the connecting seat, and the other end thereof extends to the exterior of the baseplate at the main body part of the connecting seat. The utility model effectively solves the stress concentration problem of the connecting part of the cross beam and the inner side of a side beam, reduces difficulty in processing and manufacturing, facilitates manufacture, reduces welding quantity and polishing quantity, and improves production efficiency.
Description
Technical field the utility model relates to a kind of urban rail car, particularly its truck frame.
Background technology urban rail car bogie truck end is installed the framework of disc brake and mainly is made up of crossbeam and curb girder, be the cooresponding with it two groups of through holes of box curb girder that two parallel round steel pipe crossbeam both sides are passed two symmetries respectively, and crossbeam and curb girder intersection position composition " well " the font framework that is weldingly connected.Find through the framework finite element analysis, when this bogie truck apply brake, the inboard riser connecting portion of crossbeam and curb girder has the serious stress concentration phenomenon, be connected static strength and strength at repeated alternation for what guarantee crossbeam and curb girder, make its loading stress in certain stress amplitude scope, need to increase certain knuckle, so that dispersive stress effectively at bonded assembly intersection position.At present, the more advanced practice is: the intersection position built-up welding that is connected at inboard riser of curb girder and crossbeam goes out very high fillet weld, polish the required radius of rounding of dispersive stress (usually more than R25) then.Its weak point is: this big welding capacity structure causes the serious shrinkage distortion of framework easily, and the processing and manufacturing difficulty is big; Polishing amount simultaneously is big, production efficiency is low.
The summary of the invention the purpose of this utility model is to provide a kind of dispersive stress effectively can reduce processing and manufacturing difficulty, framework round steel pipe crossbeam Connection Block that production efficiency is high again.
The utility model mainly is to establish Connection Block with the junction of crossbeam on the inboard riser of curb girder.This Connection Block base portion includes base plate and boss platform.Wherein, the base plate profile is not limit, and preferably the shape with curb girder inner vertical plate entablatrance connecting through hole part matches, promptly base plate be about two limits can link to each other with the cover plate up and down of curb girder respectively, about two quadrangles that side can link to each other with inner vertical plate respectively.This base plate middle part is provided with through hole, its with the boss platform that is connected as a single entity in the through hole coaxial line and both diameters all less than the crossbeam diameter, for secondary processing leaves surplus.Establish knuckle between above-mentioned boss platform outer peripheral face and the base plate, it is between R25-R30.Be provided with the tubular positioning table in addition in the through hole of above-mentioned Connection Block base portion, the one partial fixing is in the through hole of Connection Block base portion, and another part reaches the outside of Connection Block base portion base plate.The utility model compared with prior art has following advantage:
1, the utility model has solved the problem of stress concentration of crossbeam and the inboard connecting portion of curb girder effectively.Adopt ANSYS finite element analysis means, framework integral body is carried out the static strength and the Fatigue Strength Analysis of various operating modes, confirm that the utility model can satisfy the Joint strenght requirement of framework under various force status; Static strength and punishing stress test by the framework simulated condition have also confirmed The above results.
2, alleviated the processing and manufacturing difficulty, the convenient manufacturing.
3, reduced welding capacity and polishing amount, enhanced productivity.
Description of drawings
Fig. 1 is that the utility model master looks scheme drawing.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is that the master that the utility model is assembled on the curb girder looks scheme drawing.
Fig. 4 is the B-B view of Fig. 3.
Fig. 5 is the utility model running condition cross-sectional schematic.
The specific embodiment is in the scheme drawing of framework round steel pipe crossbeam Connection Block illustrated in figures 1 and 2, the shape of base plate 2 profiles of this Connection Block 1 base portion and curb girder 3 inner vertical plates 4 entablatrance connecting through holes part matches, promptly base plate be about two limits can link to each other with the cover plate up and down of curb girder respectively, about two quadrangles that side can link to each other with inner vertical plate respectively.Through hole is established at this base plate middle part, its with the boss platform 5 that is connected as a single entity in the through hole coaxial line and both diameters all less than the crossbeam diameter.Establish the knuckle of R25 between above-mentioned boss platform outer peripheral face and the base plate.Be provided with tubular positioning table 6 in the through hole of above-mentioned Connection Block base portion, the one partial fixing is in the through hole of Connection Block base portion, and another part reaches the outside of Connection Block base portion base plate.The installation of above-mentioned Connection Block: the positioning table cylindrical that will stretch out Connection Block places in the crossbeam connecting through hole of curb girder inner vertical plate, as shown in Figure 3 and Figure 4, is the Connection Block location with it, then the Connection Block base plate is soldered on the corresponding part of curb girder inner vertical plate.The through hole that when curb girder carries out secondary processing Connection Block is linked to each other with crossbeam is processed, the external diameter of its internal diameter and crossbeam round steel pipe is complementary, and positioning table machined away, as shown in Figure 5, so that crossbeam 7 can be inserted in the through hole of Connection Block, guarantee that again two pitch-rows of two Connection Blocks are consistent with the crossbeam width between centers simultaneously.
