detailed description

As shown in FIG. 1 and FIG. 2, an anti-drop rail crusher comprises a pressure plate 4 provided with a through hole, a screw 5 is inserted through the through hole of the pressure plate 4, and the screw 5 runs through the leveling layer 1 and the cement beam 100, and the leveling layer A connecting bar 101 is provided between the cement beam and the cement beam. A nut 6 is provided at the upper end portion of the screw 5, and the pressure plate 4 and the backing plate 2 under the rail are fixed by the screw 5 and the nut 6. In order to prevent the nut 6 from slipping backward, a nut lock-proof card 7 is disposed on the outer side of the nut 6. As shown in FIG. 4, the nut lock-up card 7 includes a mounting hole 75 disposed in the middle of the nut lock-up card body and is connected to the body. The upper anti-loose mechanism, wherein the mounting hole 75 is matched with the outer side surface of the nut 6, and the anti-loose mechanism can prevent the nut anti-loose card 7 and the nut 6 from being reversed.

In Fig. 3(a)-(e), the bottom of the backing plate 2 is provided with a non-slip table 10, and the anti-slip table 10 penetrates into the cement pillow and the concrete, which can prevent the lateral displacement and longitudinal displacement of the track, and improve the locomotive. Safety factor.

In addition, in order to better implement the present invention, the pressing plate 42 of the pressing plate 4 in contact with the rail 3 is provided with an elastic pressing tongue 41, and the pressing portion 42 is provided with a dimple, and the pressing tongue 41 is placed in the dimple, as shown in FIG. Figure 6 shows.

As shown in Fig. 5, the nut lock-out card 7 is provided with a closing cap 51 at the upper end portion of the screw 5 to facilitate sealing of the mounting hole 75 and prolong its life. The nut with the closing cap can prevent the upper end of the screw from forming a closed space, which can be waterproof and dustproof. If butter 52 is applied in the space, the butter can be prevented from leaking out and the air pollution can be reduced. Can extend its service life. The bottom of the closure cap 51 is sealed by liquid from dry rubber water 53.

There are many kinds of nut anti-loose card 7 and its anti-loose mechanism. This patent gives the following five implementations of A-E:

A: As shown in Fig. 7, Fig. 8(a) and Fig. 8(b), the lock mechanism means that the nut lock mechanism body extends downward to form an extension portion 71, and the end portion of the extension portion 71 is connected to the anti-slip portion. 72. The end of the anti-slip portion 72 is provided with a hook 73. The hook 73 is approximately perpendicular to the anti-slip portion 72, and the hook 73 is hooked on the lower end surface of the pressing plate 4, so that the anti-loose mechanism clamps the pressing plate 4 through the hook 73, thereby preventing the nut from being loosened. The card 7 and the nut 5 are reversed.

It should be noted that the extension portion 71 of the above-mentioned nut lock-proof card 7 may be provided only one or two symmetrically (only one is shown in FIG. 7).

During installation, as shown in Fig. 1-8, in the track casting layer, the pad 2 and the screw 5 are preliminarily pressed, and the pressing portion of the pressing plate 4 is pressed on the rail 3, and the nut anti-locking card 7 is placed on the nut 6, and the rotation is performed. The platen 4 and the pad 2 are fixed and rotated to a certain position, and the hook 73 at the lower end of the anti-slip portion 72 of the nut locker 7 is hooked on the surface of the side of the pad 2 of the platen 4.

After tightening, because the nut is loosened, when the locomotive vibrates through the track, the anti-slip part of the nut anti-loose hook is not loosened, so the nut will not slip and affect the use.

Nut anti-loose card 7 can be divided into no loose single hook nut card Figure 9 (a), no loose double hook nut card Figure 9 (b), no loose single hook nut protection card Figure 9 (c) and no loose double hook nut The protective card Figure 9(d) can be designed according to the on-site installation environment. The above can be used alone or in combination.

In use, the gauge adjustment plate utilizes the wedge principle, and the error of the stepless adjustment of the gauge distance and the track center distance is zero, ensuring smooth and smooth running of the wheel without friction.

B: As shown in FIG. 10-13, the anti-loose mechanism is a laterally extending anti-slip block 81, and a non-slip protrusion 82 is disposed at a corresponding position of the anti-slip block 81 on the upper surface of the pressure plate 4, and the anti-slip block 81 contacts the anti-slip protrusion 82, In cooperation, the nut lock card 7 is prevented from being reversed. The edge of the non-slip projection 82 is provided with a shield for the escape of the anti-slip block 81.

When the nut lock-proof card 7 is sleeved on the nut 6, it is rotated backward a little, so that the anti-slip block 81 enters the underside of the guard plate, and after the anti-slip block 81 contacts the anti-slip protrusion 82, the two cooperate to prevent the nut lock-up card 7 from being reversed. . When the locomotive vibrates through the track, the nut does not slip due to the action of the nut against the loose card, which affects the use.

The nut anti-loose card 7 in this embodiment is a loose single-arm nut card, respectively, Figure 13 (a), no loose-arm nut, Figure 13 (b), no loose single-arm nut protection card, Figure 13 (c), and none. The loose-arm nut protection card Figure 13(d) can be designed according to the site installation environment.

C: As shown in FIG. 14-22, the anti-loose mechanism is a laterally extending anti-slip block 81. The upper surface of the pressure plate 4 is provided with two symmetrical arc-shaped protrusions 44, and the corresponding positions of the anti-slip blocks 81 on the sides of the arc-shaped protrusions 44 are provided. There is a non-slip groove 85, and after the anti-slip block 81 enters the anti-slip groove 85, the two cooperate to prevent the nut lock card 7 from being reversed.

When the nut lock-proof card 7 is placed on the nut 6, it is rotated a little backward, so that the anti-slip block 81 enters the inside of the anti-skid groove 85, and the two cooperate to prevent the nut lock-up card 7 from being reversed. When the locomotive vibrates through the track, the nut does not slip due to the action of the nut against the loose card, which affects the use.

As shown in Fig. 15, the contact surface of the card slot and the nut card arm (enlarged detail), the upper surface of the card slot and the upper surface of the nut card arm 151 are mutually matching contact faces, and the nut lock card arm enters the card slot. When inside, not only the looseness of the nut is prevented, but also the nut card is clamped, which prevents the shock generated by the locomotive from passing over and the vibration of the nut card from jumping off and squeaking.

As can be seen from Figures 16, 17, 18, 19, the base may be a single hole weld 161 or a double hole weld 162, and the corresponding upper platen may also be a single hole 163 or a double hole 164.

In the above three schemes A, B and C, the nut lock-proof card 7 is matched with the pressure plate 4 to prevent the nut lock-up card 7 from being reversed.

D, E: As shown in Fig. 23-30, a butterfly card 91 is arranged on the upper surface of the pressure plate 4, the nut 5 is pressed on the upper surface of the butterfly card 91, the anti-loose mechanism is a longitudinally extending longitudinal extension 99, and the longitudinal extension 99 is provided with a non-slip inner side. The groove, the anti-slip groove can be caught on the upper portion of the butterfly card 91.

In order to better fix the butterfly card 91 and the pressure plate 4, a butterfly card pocket 98 is provided on the pressure plate 4 of the contact surface thereof, and the butterfly card pocket 98 may be one (see Fig. 26), and a plurality of the butterfly card pockets are also arranged in parallel (see Figure 30), the contact portion of the butterfly card 91 is placed in the butterfly card pocket 98.

When the nut lock-proof card 7 is placed on the nut 6, it is rotated a little backward, so that the anti-slip groove is caught on the upper part of the butterfly card, and the two cooperate to prevent the nut lock-up card 7 from being reversed. When the locomotive vibrates through the track, the nut does not slip due to the action of the nut against the loose card, which affects the use.

The card slot nut card of Figure 27 is divided into a loose card slot nut card Figure 27 (a) and a loose card slot nut protection card Figure 27 (b), which can be selected according to the site installation environment.
