Description

Technical Field

[0001] The invention relates to the technical field of rail vehicles, and in particular to an isolation cover for preventing snow accumulation and a train bogie having the isolation cover. Background Art

[0002] For high-speed trains, when the train runs at high speed, due to air flow, the braking area of ​​the bogie is mainly negative pressure. There are a large number of vortices with low flow rate in this area, which are easy to absorb snow particles and accumulate, which leads to ice on the brake disc. Since the brake disc mainly brakes through friction between the brake shoe, when ice forms on the brake disc, the friction between the brake disc and the brake shoe will be reduced, thereby affecting the braking performance of the train, increasing the sliding distance of the train during braking, and even failing to brake, causing accidents. However, there is no effective protective device on the existing train braking device to prevent ice from forming in the braking area. Summary of the invention

[0003] The object of the present invention is to provide an anti-snow isolation cover and a train bogie with the isolation cover, wherein the anti-snow isolation cover can prevent air carrying snow particles from entering the braking area, and the train with the isolation cover has good braking performance in windy and snowy weather.

[0004] The technical solution of the present invention to solve the above technical problems is as follows:

[0005] A snow-proof isolation cover comprises: a top plate and a rear plate which are detachably arranged on a train bogie, and a front baffle, a front plate and a bottom plate which are arranged in sequence between the top plate and the rear plate; the top plate, the rear plate, the bottom plate, the front baffle and the front plate form a hollow cover body with openings at both ends, and a first side plate and a second side plate are respectively arranged at both ends of the hollow cover body.

[0006] The anti-snow isolation cover is arranged in the braking area of ​​the train bogie, which can isolate the braking area from the outside world, thereby preventing the outside air from forming a vortex or negative pressure in the braking area, thereby reducing the absorption of snow particles in the braking area. The isolation cover is surrounded by five plates, namely, a top plate, a rear plate, a bottom plate, a front baffle plate and a front plate, to form a hollow cover body, and a first side plate and a second side plate are arranged at both ends of the cover body opening, so as to surround the braking device in the cover body. The top plate and the rear plate are arranged on the existing structure of the bogie, which can save a certain amount of space without making too much change to the bogie, making the isolation cover more applicable and more convenient to install and disassemble. The five plates are arranged along a 360° circle, and any plate can be removed for inspection at a certain position, and the visual range is reasonably distributed.

[0007] Furthermore, in a preferred embodiment of the present invention, the anti-snow isolation cover is a convex pentagonal prism structure, and the bottom plate is parallel to the ground.

[0008] The isolation cover is a convex pentagonal prism structure with a bottom plate parallel to the ground. The bottom plate can prevent wind and snow on the ground track from entering the braking area. The side plates are tilted to avoid snow accumulation. The rear plate can effectively isolate the wind and snow behind the braking area of ​​the bogie. The front plate and the front baffle extend obliquely upward and downward from their connecting edges respectively, so that the high-speed airflow carrying snowflake particles in the front can be diverted along the front plate and the front baffle to obliquely upward and downward. The first side plate and the second side plate at both ends close the isolation cover to prevent upward airflow from entering the braking area from both sides.

[0009] Furthermore, in a preferred embodiment of the present invention, the end where the top plate is connected to the front plate is provided with a slope that is inclined relative to the plate surface of the top plate, the slope is provided with a first slot, and the end where the front plate is connected to the top plate is provided with a first protrusion that cooperates with the first slot.

[0010] The top plate and the front plate are detachably connected through the cooperation of the first slot and the first protrusion. Since the top plate and the front plate are not vertically arranged, the first slot is arranged on a slope with a certain angle. From a geometric point of view, the angle between the slope and the surface of the top plate plus 90° is the angle between the top plate and the front plate.

[0011] Furthermore, in a preferred embodiment of the present invention, first bolt holes are respectively provided at both ends of the first slot and the first protrusion, and bolts connect the top plate and the front plate through the first bolt holes.

[0012] To further fix the top plate and the front plate, the two ends of the slot and the protrusion are connected again by bolts.

[0013] Furthermore, in a preferred embodiment of the present invention, the front plate and the front baffle, the front baffle and the bottom plate, and the bottom plate and the rear plate are all detachably connected by means of the cooperation of the first slot and the first protrusion.

[0014] Furthermore, in a preferred embodiment of the present invention, the inner wall surfaces at both ends of the top plate, front plate, front baffle plate, bottom plate and rear plate are respectively provided with second card grooves, and the first side plate and the second side plate are correspondingly provided with second protrusions that cooperate with the second card grooves, and the first side plate and the second side plate are detachably connected to the top plate, front plate, front baffle plate, bottom plate and rear plate through the second card grooves and the second protrusions.

[0015] Second card slots matching the first side panel and the second side panel are provided on the inner wall surfaces at both ends of the top panel, the front panel, the front baffle panel, the bottom panel and the rear panel, so that the first side panel and the second side panel can be clamped in the second card slots, so that the edges of the first side panel and the second side panel are respectively connected to the top panel, the front panel, the front baffle panel, the bottom panel and the rear panel, with a simple structure and easy installation.

[0016] Furthermore, in a preferred embodiment of the present invention, at least one row of second bolt holes is provided on the side wall of the second slot and on the second protrusion, and bolts are used through the second bolt holes to detachably connect the first side plate and the second side plate to the top plate, front plate, front baffle plate, bottom plate and rear plate respectively.

[0017] To further enhance the fixing effect, the first side plate and the second side plate not only need to be clamped in the second clamping groove, but also need to be fixed to the top plate, the front plate, the front baffle plate, the bottom plate and the rear plate by bolts.

[0018] Furthermore, in a preferred embodiment of the present invention, the first side plate and the second side plate are provided with through holes for the main axle of the train to pass through.

[0019] Through holes are provided on the first side plate and the second side plate at the position of the train main shaft. The number, size and position of the through holes are not specifically limited and can be adjusted according to the actual structure of the train bogie. The size of the through holes should not be too large to avoid wind and snow entering the isolation cover from the gap between the through holes and the main shaft. Similarly, the size of the through holes should not be too small to avoid affecting the rotation of the main shaft.

[0020] A train bogie with an anti-snow isolation cover comprises a bogie body and anti-snow isolation covers detachably arranged at both ends of the bogie body, wherein braking devices are arranged at both ends of the bogie body and the anti-snow isolation covers are arranged around the braking devices.

[0021] The train bogie is equipped with the above-mentioned anti-snow isolation cover in the braking area. The isolation cover only needs to be set in the braking area of ​​the bogie and has no effect on other structures. The isolation cover can be detachably arranged on the train bogie, and whether to install the isolation cover can be selected according to the weather.

[0022] Furthermore, in a preferred embodiment of the present invention, the braking device includes a brake disc and a brake shoe arranged corresponding to the brake disc, a brake shoe bracket for supporting the brake shoe is provided on the bogie body, at least one row of third bolt holes is provided on the top plate, and the bolts fix the top plate to the upper end of the brake shoe bracket through the third bolt holes, the inner wall surface of the top plate abuts against the brake shoe bracket, and the rear plate is arranged on the bogie body below the brake shoe bracket.

[0023] The top plate of the isolation cover is installed on the brake shoe bracket of the bogie, and the rear plate is also installed on the bogie body. There is no need to add other mounting structures on the bogie, and the upper surface of the brake shoe bracket is inclined, so that the top plate is also inclined. Compared with a flat surface, the inclined surface is not easy to accumulate snowflakes.

[0024] The present invention has the following beneficial effects:

[0025] The present invention provides an isolation cover and a train bogie with the isolation cover for a high-speed train running in severe weather such as cold, windy and snowy weather. The isolation cover is in the form of a convex pentagonal prism structure as a whole, and is closed on all sides, so as to block the entry of wind and snow from all directions, and can effectively divert the wind and snow from all directions to prevent the wind and snow from entering the braking area. Compared with the existing bogies, the bogie with the isolation cover has better braking performance in windy and snowy weather, and enhances the running safety of the train in windy and snowy weather. The isolation cover is easy to disassemble and assemble, and its shape and structure will not affect the performance of the bogie, and can be flexibly adjusted according to the model of the high-speed train. The various components are connected in a detachable manner, and the structure at any position can be disassembled according to the maintenance position. BRIEF DESCRIPTION OF THE DRAWINGS
