Description of drawings
Fig. 1 is the synoptic diagram of the utility model wheel rim bearing type track weighing device embodiment;
Fig. 2 is the rail transverse sectional view before the vehicle weighing among the embodiment shown in Figure 1;
Fig. 3 is the rail transverse sectional view during vehicle weighing among the embodiment shown in Figure 1.
Embodiment
The utility model is described in more detail below in conjunction with drawings and Examples.
With reference to figure 1, this wheel rim bearing type track weighing device comprises 7 two of rail, rail bearing 2 and the locker corresponding with it 1 each four pairs, is connected 6 four pairs of 5 four of support bars, height arm controls, 3 two pairs on wheel rim transition rail, LOAD CELLS 4 a pair of and weighing instrument 10 1 covers of every pair of rail bearing 2.
Four pairs of rail bearings 2 are installed in the inboard of two one steel rails 7 respectively symmetrically, and rail bearing 2 is decided according to the length of wheel rim transition rail 3 and LOAD CELLS 4 along the spacing of rail direction.Each rail bearing 2 bottom has horizontal wedge shaped recess and matches with the rail flange of rail 12 inboards, the locker 1 that utilizes transverse concave groove to be fixed on the described rail flange of rail 12 outsides equally is connected with corresponding rail bearing 2 by bolt 8, rail bearing 2 is fixed on the rail 7, between every pair of rail bearing 2 on two one steel rails 7, reinforces simultaneously by support bar 5 is installed.Be provided with vertical groove on each rail bearing 2, this vertical groove fits near the upper surface of the sidewall of rail 7 and the lower surface of rail head of rail 13.Two rail bearings 2 in the middle of every one steel rail 7 are installed the high-end of described wheel rim LOAD CELLS 4 and wheel rim transition rail 3, and all the other two rail bearings 2 are installed the low side of described wheel rim transition rail 3.Between the vertical groove of wheel rim transition rail 3 and LOAD CELLS 4 and rail bearing 2 height arm control 6 is housed, the form of height arm control 6 is a pad, can change the height of wheel rim transition rail 3 and LOAD CELLS 4 by the thickness of adjusting pad.
