Description

Technical Field

[0001] The utility model relates to the technical field of railway vehicle maintenance, in particular to an axle box cleaning device. Background Art

[0002] The ground return device is installed on the bogie axle box of the railway vehicle. Its function is to realize the ground return of the grid-side circuit from the power grid to the rail, and at the same time protect the bogie axle box bearing. It can effectively improve the conductivity of the railway vehicle and prevent the electrocorrosion of the bogie axle box bearing, thereby improving the reliability of the railway vehicle. The ground return device is generally installed axially. The carbon brush is a cylinder or a cuboid, and the contact surface is a plane. An elastic device is used to make it in close contact with the cylindrical contact disk end face of the rotating shaft. The carbon brush is soft in texture and will produce a certain amount of carbon powder under the friction with the rotating shaft. As the vehicle runs, carbon powder will gradually be generated and gathered in the cavity. If too much carbon powder is gathered, it is easy for carbon powder to enter the bearing from the maze dustproof structure, causing bearing damage, or enter other parts from the gap between the bracket and the carbon brush, causing structural damage, current transmission confusion and other problems.

[0003] A Chinese patent with publication number CN204688068U discloses a motor vehicle axle box cleaning device, which uses chemicals to clean the axle box, but it targets the highly adhesive dirt layer on the outer surface of the axle box and does not involve the cleaning of carbon powder inside the axle box.

[0024] The utility model will be further described below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 3 As shown, the axle box cleaning device of one embodiment of the utility model comprises a box body 1, an air blowing head 2 and a suction sweeping head 3. An air compressor and a fan (not shown in the figure) are arranged inside the box body 1. The air blowing head 2 is connected to the air compressor through a first hose 4, and the suction sweeping head 3 is connected to the fan through a second hose 5. Figure 4 As shown, the suction sweeper head 3 includes a joint 31, a bearing 32 and a brush head assembly 33. The joint 31 is connected to the second hose 5, and the outer ring of the bearing 32 is arranged on the joint 31. Figure 4 and Figure 5 As shown, the brush head assembly 33 is connected to the inner ring of the bearing 32, and the brush head assembly 33 includes a barrel 331, bristles 332, a bracket 333 and a fan blade 334. The bristles 332 are arranged on the end surface of one end of the barrel 331, the bracket 333 is arranged inside the barrel 331, and the fan blade 334 is arranged on the bracket 333. The rotation axis of the fan blade 334 coincides with the axis of the barrel 331. The bearing 32 and the joint 31, as well as the bearing 32 and the barrel 331 are assembled by interference fit to ensure the reliability of the connection.

[0026] The compressed air generated by the air compressor can be ejected from the air blowing head 2 through the first hose 4, and can purge the carbon powder inside the axle box. The negative pressure generated by the fan allows the external air to enter the second hose 5 through the suction head 3 and form an airflow, which drives the fan blades 334 to rotate. Since the fan blades 334 are connected to the cylinder 331 through the bracket 333, and the cylinder 331 is arranged on the bearing 32, the cylinder 331 also rotates, driving the bristles 332 arranged at one end of the cylinder 331 to clean the carbon powder inside the axle box, and the cleaned carbon powder is sucked into the second hose 5 for collection at the same time. The suction head 3 has a simple structure and has the advantages of low cost and high reliability. The axle box cleaning device of this embodiment combines the two cleaning methods of blowing and suction, which can better complete the cleaning of the carbon powder in the axle box. In the cleaning operation, you can choose to use the air blowing head 2 for blowing first, or the suction head 3 for suction first according to the actual situation.

[0027] No matter it is the air blowing head 2 or the suction sweeping head 3, the size of the end portion thereof is relatively small and an elbow design is adopted, so that it is convenient for the end portion to extend into the interior of the axle box for cleaning operations.

[0028] In this embodiment, the air blowing head 2 is detachably connected to the first hose 4, and the suction sweeping head 3 is detachably connected to the second hose 5, so as to facilitate the replacement of the air blowing head 2 and the suction sweeping head 3. In particular, the bristles 332 on the suction sweeping head 3 are consumable parts and have a high replacement frequency.

[0029] like Figure 4 As shown, the bristles 332 are cylindrical, and a plurality of bristles 332 are arranged at equal intervals on the end surface of the barrel 331, so that the brush head assembly 33 can remain stable even when rotating at high speed.

[0030] Furthermore, the distance between two adjacent bristles 332 is smaller than the diameter of the bristles 332. The bristles 332 are arranged relatively closely on the end surface of the cylinder 331 to achieve a better cleaning effect. Some bristles 332 can be made of harder materials, while other bristles 332 can be made of softer materials, and are arranged in an alternating manner. The harder bristles 332 can have an additional scraping effect, and the combination of two bristles 332 of different hardness can improve the cleaning effect of carbon powder.

[0031] like Figure 5 As shown, the bracket 333 is cross-shaped, and the fan blade 334 is fixedly connected to the middle of the bracket 333. The cross-shaped bracket 333 has a smaller cross-sectional area and better stability, and does not cause a large obstruction to the airflow while providing stable support for the fan blade 334.

[0032] like Figure 1 and Figure 2As shown, the top of the box 1 is provided with a plurality of power sockets 11, which can power electric tools and other equipment without laying power cables, and is convenient to use. The top of the box 1 in this embodiment is relatively flat, and there is a large area for placing various tools.

[0033] like Figure 1 and Figure 2 As shown, two drawers 12 are provided on one side of the box 1. Small tools, consumables, etc. can be placed in the drawers 12, so that the small tools and consumables are not easy to lose. The two drawers 12 can be used to place different types of items respectively to achieve classified storage.

[0034] like Figure 1 and Figure 2 As shown, a shutter 13 is provided on one side of the box body 1, so that the air compressor, fan and other components inside the box body 1 can obtain good heat dissipation while also reducing noise to a certain extent.

[0035] like Figure 1 and Figure 2 As shown, a roller assembly 6 is provided at the bottom of the box body 1, so that the axle box cleaning device can be conveniently moved around the axle box during operation, avoiding frequent movement of heavy axle boxes and reducing labor intensity.

[0036] Further, the roller assembly 6 includes a wheel body 61 and a suspension 62, the suspension 62 is arranged at the bottom of the box body 1, and the wheel body 61 is connected to the suspension 62. The suspension 62 can provide a certain buffer, reduce the vibration of the components inside the box body 1, and reduce the failure rate.

[0037] like Figure 1 and Figure 2 As shown, handles 14 are provided on both sides of the box body 1 to facilitate the overall movement of the axle box cleaning device.

[0038] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
