Description
Technical field
The present invention relates to mechanical technique, particularly relate to a kind of positioning and locking assembly, across boom device and railway freight-car.
Background technique
At present, goods train vehicle installs empty and load brake equipment on car body, spring height is rested the head on the variable quantity under the different operating mode of vehicle load by the contact induction bogie of empty and load brake equipment, to go the size controlling brake cylinder air pressure as control signal, thus make vehicle under the situation of different carrying capacity, obtain corresponding braking force, avoid vehicle under sky, the different operating mode of loaded vehicle because braking force does not mate the various faults caused.
For making empty and load brake equipment 1 realize above-mentioned functions, need to arrange corresponding with empty and load brake equipment 1 across boom device.Fig. 1 a is the scheme of installation across boom device in prior art, Fig. 1 b is the structural representation across boom device in Fig. 1 a, see Fig. 1 a and Fig. 1 b, comprise across beam 3 and the touch panel 4 that is weldingly fixed in the middle part of across beam across boom device, touch panel 4 is for the contacts mates effect with empty and load brake equipment 1.During installation, be erected in the bogie side frames 2 that on railway freight-car, relative rail level vertical deviation is less across beam 3.
After the wheel wear of railway freight-car, vehicle coupler height declines thereupon, but in actual applications, the height of hitch must ensure in professional standard, to meet coupling of vehicles requirement.So after vehicle abrasion, in order to make, hitch is high meets relevant criterion, just need between the lower core plate and bolster of bogie, to install backing plate additional, to raise car body.After car body is raised, the height being arranged on the empty and load brake equipment 1 on car body can along with raising, and the height across boom device be arranged in bogie side frames 2 remains unchanged, so empty and load brake equipment 1 contact and across boom device touch panel 4 between spacing increase, empty and load adjustment is made to fill the change that cannot judge bogie camber of spring, thus ineffective.Therefore, the height across boom device must be raised thereupon, and allowing the finite thickness of cushioning across boom device and side frames 2 point of attachment, at this moment, just need across the touch panel 4 of boom device increasing adjustment backing plate 5, to meet the usage requirement of empty and load brake equipment 1.In prior art, solve the problems referred to above, specifically see Fig. 1 b by direct mode of welding one piece of adjustment backing plate 5 above touch panel 4.
At least there is following problem in prior art: be welded and fixed between touch panel and adjustment backing plate, welding operation can consume a large amount of electric power, welding rod and other auxiliary materials, and can cause serious environmental pollution, and serious harm operator's is healthy; In addition, touch panel easily produces distortion, reduces the measuring accuracy of empty and load brake equipment.
