DETAILED DESCRIPTION

[0014] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0015] Refer to the attached Figure 1-3 A heavy-duty flexible wheel-stopping device comprises a movable base, a fixed base, an arc plate 4, a supporting vertical plate 1 5, a top connecting plate 8, a handle 9 and a supporting vertical plate 2 13. The movable base and the fixed base are both U-shaped structures composed of two side plates and a top plate combined together and matched with a track. The movable base is slidably connected to the track, the fixed base is fixedly connected to the track, the arc plate 4 and the supporting vertical plate 1 5 are fixed to the movable base, the supporting vertical plate 2 13 is fixed to the fixed base, the supporting vertical plate 1 5 and the supporting vertical plate 2 13 are connected together through the top connecting plate 8, and a handle 9 is provided on the top connecting plate 8.

[0016] In this embodiment, refer to the attached Figure 1-3 The wheel stop device is mainly divided into three parts: a sliding brake part, an elastic connection part and a fixed brake part, wherein: The sliding brake part mainly includes a movable base side plate 1, a movable base top plate 2, a spring 3, an arc plate 4, a support vertical plate 5, a top connecting plate 8 and a handle 9. Two movable base side plates 1 and a movable base top plate 2 are welded together to form a movable base. When making it, the movable base is first made, and two movable base side plates 1 are made according to the width of the track. The two movable base side plates 1 and the track retain a gap of 0.5-1mm; the inner surface of the movable base top plate 2 is welded with a wear-resistant layer, and the movable base side plates 1 and the movable base top plate 2 are mainly fixed by welding technology; the arc plate 4 and the support vertical plate 5 are welded on the upper part of the movable base, and the function of the arc plate 4 is to increase the contact area of ​​the wheel; The elastic connection part mainly includes a spring 26, a fixing rod 17, a flexible sealing cloth 12, a spring 316, and a fixing rod 217, which are used to connect the sliding brake part and the fixed brake part and play a buffering role. One end of the spring 26 is fixed on the supporting vertical plate 15 of the sliding brake part, and the other end is fixed on the supporting vertical plate 213 of the fixed brake part, and the middle is connected by the fixing rod 17. The spring 26 can be compressed and extended between the supporting vertical plate 15 and the supporting vertical plate 213, and plays two roles of connection and buffering impact force; in addition, the spring 316 and the fixing rod 217 are installed between the movable base top plate 2 of the sliding brake part and the fixed base top plate 18 of the fixed brake part, and their role is to connect in the horizontal direction and buffer the horizontal impact force; The fixed braking part mainly includes bolts 10, a pressure plate 11, a second supporting vertical plate 13, a supporting rib plate 14, a pull rod 15, a fixed base top plate 18, a fixed base side plate 19, a nut 20, a connecting rod 21, a pin 22, a clamping rod 23, a spring four 24, etc. Two fixed base side plates 19 and a fixed base top plate 18 are connected together to form a fixed base. During production, firstly, a fixed base top plate 18 is produced, a wear-resistant layer is welded inside the fixed base top plate 18, and then a fixed base side plate 19 is produced, an elastic material is fixed inside the fixed base side plate 19, and the two fixed base side plates 19 are connected to the fixed base top plate 18 by hinges. The clamping of the two fixed base side plates 19 is completed by a pull rod 15, a nut 20, a connecting rod 21, a pin 22, a clamping rod 23, and a spring four 24. This tightening method mainly utilizes the connecting rod principle. When in use, the clamping force is adjusted by adjusting the nut 20, and the friction force of the two fixed base side plates 19 is adjusted by the clamping force. A spring four 24 is installed between the nut 20 and the clamping rod 23, and the support vertical plate two 13 and the support rib plate 14 are fixed to the fixed base.

[0017] The top connecting plate 8 is welded together with the arc plate 4 and the supporting vertical plate 1 5 and the supporting vertical plate 2 13. The top connecting plate 8 is below the pressing plate 11 and can move under the pressing plate 11 but cannot separate from the pressing plate 11. The handle 9 is installed on the top connecting plate 8. When the handle 9 is lifted, the wheel stop device can be lifted up as a whole.

[0018] When in use, place the entire device on the track that needs to be braked, and place the movable base in the sliding brake part directly on the track and align it; the fixed brake part can be tightened by adjusting the clamping nut 20 so that the fixed base side plate 19 in the fixed base can tighten the track. The operation is simple, convenient and practical.

[0019] When the train needs to brake, the first part that comes into contact is the sliding brake part of the wheel-stopping device, that is, the wheel contacts the movable base top plate 2 and the arc plate 4. The movable base top plate 2 first generates sliding friction with the track tread, and relies on the sliding friction to perform preliminary braking on the wheel to slow down the running speed of the train. At this time, the sliding brake part moves toward the fixed brake part, and the force is first applied to the elastic connection part. The elastic connection part buffers the force again and then transmits the force to the fixed brake part. The fixed brake part receives the slowed force and completes the braking of the train.
