Description

Technical Field

[0001] The invention relates to a rail train vehicle end system, and in particular to an anti-ice and snow device for a high-speed train reconnection end. Background Art

[0002] When trains are reconnected in winter, the front opening and closing mechanism is in the open state. Snow can easily enter the front end of the train during operation, affecting the normal use of the internal equipment and even affecting the uncoupling and reconnection of the front end fully automatic coupler, causing certain impact on operation.

[0003] Through relevant research on the winter operation of EMUs at home and abroad, it was found that in order to realize the reconnection function, the locomotives of short-formation vehicles of high-speed EMUs are currently equipped with fully automatic opening and closing mechanisms at the front end, which can be automatically opened and closed during reconnection operation. During reconnection operation in winter, the opening and closing mechanism is in the open state, and a large amount of ice and snow accumulates inside the vehicle during operation, causing the internal equipment to be unable to be used normally, affecting the operation order of the EMU.

[0004] When domestic and foreign EMUs are running in multiple units, there are no relevant protective devices on the opening and closing mechanisms. A large amount of ice and snow accumulates inside the opening and closing mechanisms during operation. There is currently no mature structure or application experience for preventing ice and snow inside the opening and closing mechanisms at the multiple unit end. The common international practice is to do corresponding anti-ice and snow protection on the couplers. Currently, the method of preventing ice and snow is to add heating and protection on the surface of the couplers. Summary of the invention

[0005] The purpose of the present invention is to solve the problem of snow entering the front end of the opening and closing mechanism and affecting the normal use of the internal equipment at the front end when the high-speed EMU is in vehicle-end multiple-unit operation.

[0006] In order to achieve the above-mentioned purpose, the present invention provides an anti-ice and snow device for the coupled end of a high-speed train, comprising a bellows assembly, a cloth-inserted profile, an intermediate docking frame, a quick connection device and a support mechanism, wherein the bellows assembly comprises two bellows of an arched structure, one end of each bellows is installed at the opening of the front opening and closing mechanism through a quick connection device, the other ends of the two bellows are connected at the hook connection surface through the intermediate docking frame and sewn by sewing thread, the cloth-inserted profile fixes the upper and lower edges of the bellows assembly, the cloth-inserted profile is crimped by a clamp, the support mechanism is arranged on the mounting surface of the coupler head, the support mechanism is connected to the upper intermediate docking frame by bolts, and the support mechanism can prevent the anti-ice and snow device from sinking during operation and interfering with the coupler.

[0007] Furthermore, a sealing tape is installed at the position of the middle docking frame of the entire bellows assembly.

[0008] Furthermore, the quick connection device includes a base, a pressure plate, a pin and a handle, the base is provided with a pressure plate, one side of the base is provided with a pin, and the handle is welded to the pressure plate.

[0009] The present invention can not only meet the requirements of trains passing through curves, but also has a certain protective effect on the front-end equipment of the train, and has a certain guiding significance for the design of the opening and closing mechanism of high-speed EMUs. The entire device has a sealed structure and a streamlined design, has good aerodynamic performance, and is light in weight. When the vehicle is running at high speed, the air resistance is diverted and reduced, and can meet the requirements of the use of high-speed EMUs. BRIEF DESCRIPTION OF THE DRAWINGS
