Description

Technical Field

[0001] The utility model belongs to the technical field of rail transportation, and in particular relates to a railway vehicle axle protection device. Background Art

[0002] Axles, as core components of railway vehicles, have a direct impact on train safety. During high-speed operation, axles are inevitably impacted by foreign objects such as track sand and ballast, causing surface damage and compromising train stability and safety. Currently, high-speed EMU axles are primarily treated with paint for corrosion protection, but this coating is thin and has limited impact resistance, making it difficult to meet the protection requirements of high-speed operation.

[0003] The invention, with publication number CN117429473B, relates to the technical field of railway vehicle protection devices, specifically a railway vehicle axle protection device, comprising a wheel and an axle, the wheels being mounted at both ends of the axle, a cleaning mechanism and a crushing mechanism being disposed at the bottom of the vehicle, the cleaning mechanism comprising a set of fixed boxes fixedly connected to the bottom of the vehicle, a first rotating shaft connecting the two fixed boxes, a first synchronous belt connecting the first rotating shaft to the axle, and a support frame being fixedly connected to one end of the fixed box away from the wheel. Through a first curved pipe, when the mine car is in operation, the cleaning mechanism and the crushing mechanism cooperate, allowing obstacles on the rails to enter the fixed box along the first pipe. The rotation of the spiral blades causes the obstacles to slide out of the fixed box through the second pipe and be discharged outside the rails, thereby preventing the wheels from repeatedly running over obstacles and damaging the axle and wheels over long-term use. Simultaneously, a cleaning block at the bottom of the first pipe removes smaller debris from the rails, further cleaning the rails.

[0004] However, the aforementioned patent also has the following problems: While the use of a synchronous belt as a transmission mechanism enables the automatic operation of the cleaning mechanism to a certain extent, the synchronous belt, as a consumable part, wears and ages rapidly under long-term, high-intensity operation, requiring regular inspection and replacement. This not only increases the complexity of operation and maintenance, but also may cause the device to fail due to accidental damage to the synchronous belt, posing a safety hazard.

[0005] In view of this, the present utility model is proposed. Utility Model Content
