Description

Technical Field

[0001] The utility model relates to the technical field of wheel stoppers, in particular to a wheel stopper for urban rail vehicles. Background Art

[0002] The wheel stopper, also known as the "iron shoe", is an important tool in railway operations. It is mainly used to prevent locomotives and vehicles from slipping. The wheel stopper is usually set on the rail track. After the wheel rolling forward presses the wheel stopper, it slides along the rail. The rolling friction between the wheel and rail is converted into sliding friction, thereby preventing the wheel from moving forward and thus playing a braking role. The wheel stopper of urban rail vehicles in the existing technology is usually set as an integral part. Since the wheel stopper needs to be used frequently and exposed to harsh environments, its maintenance and servicing costs are relatively high when it wears out.

[0003] In view of the above problems, it is necessary to provide a wheel stopper for urban rail vehicles that is easy to repair and replace. Utility Model Content

[0027] The cam 306 is provided on the side of the cam 306 away from the telescopic guide rod 301, and a mounting spring 302 is provided on the outside of the telescopic guide rod 301 and between the two limiting slides 303. A connecting rod 304 is fixedly connected to one side of the limiting slide 303. An adjusting block 305 is provided on the side of the connecting rod 304 away from the limiting slide 303 and located on the outside of the connecting plate 107. The limiting slide 303 is slidably arranged in the matching groove 111. Adjustment grooves are provided on both sides of the connecting plate 107. The end of the connecting rod 304 away from the limiting slide 303 passes through the adjusting groove and is connected and installed with the adjusting block 305, and the connecting rod 304 is slidably arranged in the adjusting groove. The end of the mounting rod 306 away from the limiting slide 303 passes through the connecting plate 107 and is connected to the mounting spring The mounting holes 104 cooperate with each other, the connecting block 108 is slidably arranged inside the mounting groove 105, and the limiting slider 109 is slidably arranged inside the limiting slide groove 106. After the urban rail vehicle wheel stopper has been used for a period of time and the brake plate 103 is greatly worn, the worker can press the two adjustment blocks 305 in sequence, and drive the two limiting slide plates 303 to move toward each other under the action of the connecting rod 304, and the telescopic guide rod 301 and the mounting spring 302 are compressed until the mounting rod 306 is disengaged from the mounting hole 104, so that the worn brake plate 103 can be removed from the top of the connecting plate 107. Then, the new brake plate 103 is placed on the top of the connecting plate 107 in the same way.

Under the action of the buffer spring 203, the impact force and vibration generated by the wheel stopper during braking can be absorbed and dispersed, thereby reducing damage to the vehicle structure, wheels and rails.

[0029] The working process of the utility model is as follows: when using the urban rail vehicle wheel stopper, the wheel first presses onto the front end of the base plate 1, and then the wheel presses onto the inclined brake plate 103, and the vehicle is braked under the action of the brake plate 103. During the braking process, under the guidance of the limiting slider 109 and the limiting slide groove 106, the connecting block 108 slides inside the mounting groove 105, thereby driving the buffer spring 203 to be compressed under the action of the buffer rod 205, the movable connecting head 204 and the slider 202. Under the action of the buffer spring 203, the impact force and vibration generated by the wheel stopper during the braking process can be absorbed and dispersed, thereby reducing damage to the vehicle structure, wheels and tracks. At the same time, the impact force and vibration generated by the wheel stopper during the braking process can be absorbed and dispersed, thereby reducing damage to the vehicle structure, wheels and tracks. To prevent damage to the track, after the brake plate 103 of the urban rail vehicle wheel stopper has been used for a period of time and has shown significant wear, the worker can press the two adjustment blocks 305 in sequence, and under the action of the connecting rod 304, the two limit slides 303 are driven to move toward each other, and the telescopic guide rod 301 and the mounting spring 302 are compressed until the mounting rod 306 is disengaged from the mounting hole 104, so that the worn brake plate 103 can be removed from the top of the connecting plate 107, and then the new brake plate 103 is placed on the top of the connecting plate 107 in the same way. Under the action of the mounting spring 302 and the telescopic guide rod 301, the mounting rod 306 is ensured to be clamped inside the mounting hole 104, completing the installation and fixation of the brake plate 103, thereby completing the replacement of the worn parts. The operation is simple and convenient and can effectively save costs.
