Referring to fig. 1, 2 and 3, a wind-resistant skate is provided for positioning on a rail 20 to stop a wheel 10 of a rail vehicle.

The wind-proof iron shoe provided by the embodiment mainly takes the typical iron shoe main body 40 as a main body, keeps the thrust structure and can realize the basic function. In order to further improve the stability of the iron shoe main body 40 on the rail 20, avoid sliding along the rail and limit the lateral swing, the windproof iron shoe further comprises, on the basis of the iron shoe main body 40: a lateral brace 60 and a lateral hold-down bolt 70.

Specifically, the lateral support plate 60 is fixed to the iron shoe body 40 and rigidly connected to the iron shoe body 40 to form an integrated stressed structure, so that when the lateral pressing bolt 70 is screwed to the lateral support plate 60 and abuts against the side of the rail 20 through the lateral pressing bolt 70, the lateral swing of the iron shoe body 40 can be limited, and the locking effect can be exerted on the iron shoe body 40, so that the fixing effect of the iron shoe body 40 can be further strengthened, and the thrust performance can be improved.

It should be noted that, in the assembled and used state, the plate surface of the lateral support plate 60 faces the side of the rail 20, the lateral pressing bolt 70 abuts against the side of the rail 20, the pushing torque of the lateral pressing bolt 70 is substantially maintained at the radial side of the lateral pressing bolt 70, and no other directional component is generated, so that the pressing force of the lateral pressing bolt 70 is fully used to enhance the contact pressure acting on the rail 20, increase the friction force, and enhance the thrust effect.

The rail 20 is clamped in both directions for stable and balanced fixing of the skate body 40. Namely, the side brace 60 includes, corresponding to both side portions of the rail 20: a first leg 61 and a second leg 62. The first support plate 61 and the second support plate 62 are arranged in parallel and are adaptive and parallel to two side wall surfaces of the rail 20 as much as possible, so that the compression effect of the contact pressure of the lateral compression bolt is ensured.

Correspondingly, the lateral pressure bolt 70 also includes: and a first bolt group 71 and a second bolt group 72 which are respectively and correspondingly screwed and fixed on the first support plate 61 and the second support plate 62.

In the assembled use state, the first support plate 61 and the second support plate 62 are respectively arranged on two sides of the rail 20, and the head ends of the first bolt group 71 and the second bolt group 72 respectively abut against two side parts of the rail 20. Therefore, the two sides are pressed tightly, so that a larger friction force can be provided, and the thrust performance is improved; the lateral swing amplitude can be limited through double-line support, and the stability of the posture and the position of the iron shoe main body 40 is improved.

In this embodiment, in order to sufficiently improve the pressing effect, the number of the first headed bolts in the first bolt group 71 and the number of the second headed bolts in the second bolt group 72 are both two, so as to improve the pressing and supporting effects and strengthen the thrust effect; and is convenient to operate. Of course, more may be used.

In order to enhance the friction thrust effect, the head ends of the first bolt group 71 and the second bolt group 72 are provided with anti-skid gaskets, so that the anti-skid effect is improved, and the friction scratch damage to the rail 20 caused by operating the first bolt group 71 and the second bolt group 72 is reduced.

In this embodiment, the anti-slip gasket is a hard rubber pad; of course, the anti-skid gasket can be made of other materials.

In order to improve the stability of the locking posture of the lateral compression bolt, a fastening screw hole is formed in the lateral support plate 60, and the lateral compression bolt 70 is screwed on the lateral support plate 60 through the fastening screw hole; the first-stage screw connection and fixation are realized; meanwhile, a fastening nut is screwed on the lateral pressing bolt 70 and abuts against the lateral support plate 60, so that a fixing effect similar to double nuts is formed, the rotation amplitude of the lateral pressing bolt 70 is reduced, and the fastening effect is ensured.

Further, a non-return spring can be sleeved on the lateral compression bolt 70, a first end of the non-return spring abuts against the fastening nut, and a second end of the non-return spring abuts against the nut of the lateral compression bolt, so that the non-return effect is further strengthened.

For the convenience of operation, the iron shoe main body 40 is provided with a handle 50.

On the other hand, in order to reinforce the top frictional thrust effect, the length of the tongue plate 30 of the skate body 40 may be extended, so that the guide length can be increased, the slope ascent can be delayed, and the lateral pushing effect can be reduced.
