Description

Technical Field

[0001] This utility model belongs to the technical field of railway track cleaning equipment, and in particular relates to an automatic railway track blowing and sweeping device. Background Technology

[0002] Railway tracks, also known as rails, are primarily used on railways and work in conjunction with switches to allow trains to travel without turning. A railway track typically consists of two parallel steel rails fixed to sleepers, beneath which lies the ballast. These rails are secured by railway accessories such as rail braces, fasteners, rail clamps, rail clips, elastic clips, and railway spikes. Currently, because railway tracks are exposed to the external environment for extended periods, their surfaces easily accumulate dirt and grime, such as leaves and small stones. Prolonged contact with this dirt can lead to corrosion of the rail surface, and the crushing of small stones can further damage the surface, causing it to rust easily. Therefore, to prevent this, the rail surface is typically cleaned manually periodically. However, due to the considerable length of the rails, cleaning is labor-intensive and inefficient. Therefore, there is an urgent need for an automatic rail cleaning device to address this problem. Utility Model Content

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides an automatic rail cleaning device, such as... Figure 1-5 As shown, it includes: base 2, guide wheel 3, auxiliary wheel 4, transmission rod 5, blowing mechanism 6 and transmission mechanism 7;

[0023] The guide wheel 3 is connected to the front end of the base 2, the transmission rod 5 is rotatably connected to the rear end of the base 2, the auxiliary wheel 4 is symmetrically and coaxially fixed at both ends of the transmission rod 5, and the guide wheel 3 rolls against the rail 1.

[0024] The purging mechanism 6 includes a servo motor 61, a worm gear 62, a driven rod 63, a fan blade 64, a protective cover 65, and an air guide pipe 66. The servo motor 61 is fixed at the center of the bottom of the base 2. One end of the worm gear 62 is coaxially connected to the output shaft of the servo motor 61. The driven rod 63 is coaxially connected to the other end of the worm gear 62. The fan blade 64 is radially fixed to the side wall of the driven rod 63. The protective cover 65 is fixed on the base 2, and the driven rod 63 and the fan blade 64 are located inside the protective cover 65. One end of the air guide pipe 66 is connected to the top of the protective cover 65, and the other end is located at the front end of the base 2. A brush plate 67 is provided at the tail end of the base 2.

[0025] It should be noted that, due to the long-term exposure of existing railway tracks to the external environment, their surfaces are prone to accumulating dirt, such as leaves and small pebbles. Prolonged contact of this dirt with the track surface can lead to corrosion, and the crushing of small pebbles can further damage the track surface, making it more susceptible to rust. Therefore, to avoid this, the track surface is typically cleaned manually periodically. However, due to the considerable length of the tracks, cleaning requires significant manpower and resources and is inefficient. To address this issue, this solution incorporates a blowing mechanism 6 and a transmission mechanism 7. The transmission mechanism 7 allows the entire device to move directionally along the track 1, eliminating the need for manual pushing. Simultaneously, the servo motor 61 drives the driven rod 63 to rotate, which in turn rotates the fan blades 64 and circulates airflow. The airflow is blown onto the track 1 surface through the air duct 66, and combined with the brush plate 67 at the tail end of the base 2, effectively cleaning the track 1 while saving time and effort, thus significantly improving work efficiency.

[0026] Specifically, in this embodiment, the solution mainly includes a rail 1, a base 2, a guide wheel 3, an auxiliary wheel 4, a transmission rod 5, a purging mechanism 6, and a transmission mechanism 7. In use, the servo motor 61 drives the worm gear 62 to rotate, the worm gear 62 drives the worm wheel 71 to mesh and move together, and simultaneously drives the active rod 72 to rotate. The active rod 72 drives the linkage rod 73 to move together, and then the linkage rod 73 drives the lever 75 to reciprocate. When the lever 75 moves, it drives the pawl 76 to rotate the ratchet 74. The ratchet 74 drives the transmission rod 5 and the auxiliary wheel 4 to rotate as a whole, so that the whole device moves on the rail 1. At the same time, the driven rod 63 rotates and drives the fan blade 64 to rotate and make the airflow flow. The airflow is blown out to the surface of the rail 1 through the air guide pipe 66, and combined with the brush plate 67 at the tail end of the base 2, the purging operation of the rail 1 can be achieved.

[0027] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, the transmission mechanism 7 includes a worm gear 71, a drive rod 72, a linkage rod 73, a ratchet 74, a lever 75, and a pawl 76. The worm gear 71 is rotatably connected to the base 2 and meshes with one side of the worm 62. One end of the drive rod 72 is connected to the axis of the worm gear 71, and the other end is rotatably connected to one end of the linkage rod 73. The other end of the linkage rod 73 is rotatably connected to the lever 75 and a horizontal plate is fixed on the base 2. The lever 75 is rotatably connected to the horizontal plate. One end of the pawl 76 is rotatably connected to the lever 75, and the other end slides against the groove at the edge of the ratchet 74.

[0028] In this embodiment, the worm gear 62 engages the worm wheel 71, thereby driving the drive rod 72, the linkage rod 73, and the lever 75 to move together. This allows the pawl 76 to rotate the ratchet wheel 74, which in turn allows the auxiliary wheel 4 and the transmission rod 5 to rotate, thus moving the entire device.

[0029] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, the ratchet 74 is a ring mechanism with slots on both the inner and outer sides, and the slots on the inner and outer sides are opposite. There are two pawls 76 on the lever 75, and the two pawls 76 respectively abut against the slots on the inner and outer sides of the ratchet 74.

[0030] In this embodiment, by setting two sets of pawls 76, one pawl 76 can slide to the next slot while the other pawl 76 can limit the ratchet 74 to prevent the ratchet 74 from reversing.

[0031] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, a protrusion is provided on the side wall of the pawl 76, and a spring 77 is provided between the protrusions of two adjacent pawls 76.

[0032] In this embodiment, the spring 77 ensures that both pawls 76 are always in contact with the ratchet 74.

[0033] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, a U-shaped wheel seat is rotatably connected to the bottom front end of the base 2, and the guide wheel 3 is rotatably connected inside the wheel seat. An arc-shaped groove is provided on the side wall of the guide wheel 3, and the rail 1 is engaged in the arc-shaped groove.

[0034] In this embodiment, the guide wheel 3 enables the entire device to move along the rail 1.

[0035] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, the brush plate 67 is provided with multiple sets of bristles, and the bristle portion slides against the rail 1.

[0036] In this embodiment, the surface of the rail 1 is brushed by the bristles of the brush plate 67.
