The technical solution adopted in the utility model: for the car body coupling device of railroad track vehicle, there is vehicle frame and truck side sill, described vehicle frame is the upper surface that high circle spring is supported in truck side sill by two, the lower surface of described vehicle frame is provided with flap seat, the lower surface of described truck side sill is provided with lower flap seat, and described lower flap seat is provided with switch block, and described switch block two ends are provided with fixed pulley, one end of steel rope is mounted on fixed pulley, and the other end of described steel rope is connected with upper flap seat by pin.
Wherein, the shape of described lower flap seat is L-type, and the lower surface of truck side sill is fixed in one end of described lower flap seat, and the other end of described lower flap seat is shaped with bearing pin, hole on described bearing pin and switch block is rotationally connected, and described switch block is limited on bearing pin by back-up ring and screw I.
Further, the length of described bearing pin 2mm larger than the thickness of switch block.
Further, described fixed pulley is fixed on switch block two ends by screw II.
Further, the length of described steel rope is less than the maximum functional amount of deflection that two are high circle spring, and the length of described steel rope is greater than vehicle frame relative to the multi-aspect side-play amount of bogie truck and vibratory magnitude sum.
The utility model beneficial effect compared with prior art:
1, the bearing pin on lower flap seat and switch block are rotationally connected, and balance the pulling force of two steel ropes when lifting by crane for car load, play steadily lifting and protection steel rope;
2, switch block two ends are connected with steel rope by fixed pulley, when vehicle frame is relative to bogie truck deflection, can ensure the steady actv. transmission of pulling force on steel rope;
3, fixed pulley and upper flap seat realize being flexible coupling by steel rope, the length of steel rope is greater than vehicle frame relative to the multi-aspect side-play amount of bogie truck and vibratory magnitude sum, the normal safe not affecting vehicle runs, so the utility model can be installed on railroad track vehicle in advance, convenient and swift during car load lifting, and the problem of misalignment of in particular cases railcar body and bogie truck can be prevented;
4, the length of steel rope is less than the maximum functional amount of deflection that two are high circle spring, prevents two to be that high circle spring damages when car load lifts by crane;
5, for dissimilar two be the railroad track vehicle of high circle spring bogie truck, length and diameter by regulating steel rope realize the function of integral lifting, have applicability widely;
6, the utility model is installed on the outside of vehicle frame and truck frame, installs simple, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing 1-2, a kind of embodiment of the present utility model is described.
For the car body coupling device of railroad track vehicle, there is vehicle frame 1 and truck side sill 5, described vehicle frame 1 is the upper surface that high circle spring 4 is supported in truck side sill 5 by two, the lower surface of described vehicle frame 1 is provided with flap seat 3, the lower surface of described truck side sill 5 is provided with lower flap seat 12, described lower flap seat 12 is provided with switch block 7, concrete, the shape of described lower flap seat 12 is L-type, the lower surface of truck side sill 5 is fixed in one end of described lower flap seat 12, the other end of described lower flap seat 12 is shaped with bearing pin 121, described bearing pin 121 is rotationally connected with the hole 71 on switch block 7, play balanced pulling force and steadily lifting, described switch block 7 is limited on bearing pin 121 by back-up ring 8 and screw I 9, wherein, the length 2mm larger than the thickness of switch block 7 of described bearing pin 121, ensure that switch block 7 can rotate around bearing pin 121 freely, described switch block 7 two ends are provided with fixed pulley 10, and described fixed pulley 10 is fixed on switch block 7 two ends by screw II 11, one end of steel rope 6 is mounted on fixed pulley 10, the pulling force of steel rope 6 is transferred on truck frame by the steady actv. of fixed pulley 10, the other end of described steel rope 6 is connected with upper flap seat 3 by pin 2, concrete, the length of described steel rope 6 is less than the maximum functional amount of deflection that two are high circle spring 4, two are effectively prevented to be that high circle spring damages when car load lifts by crane, the length of described steel rope 6 is greater than vehicle frame relative to the multi-aspect side-play amount of bogie truck and vibratory magnitude sum, the normal safe of vehicle is run unaffected.
