Description

Technical Field

[0001] The utility model belongs to the technical field of track construction, and particularly relates to a rail surface treatment device for track construction. Background Technique

[0002] Railway tracks, also known as road tracks, railway tracks, tracks, etc. They are used on railways and cooperate with switches to enable trains to move without turning. Tracks usually consist of two parallel steel rails. The steel rails are fixed on sleepers, and road ballast is placed under the sleepers. Steel rails can bear greater weights than other materials.

[0003] When performing rail surface treatment, grinding is often required, and the dust generated by grinding needs to be cleaned in a timely manner, otherwise it will affect the grinding effect. In the prior art, such as a rail surface treatment device for track construction disclosed in the publication number CN217619680U, an airbag is connected to a nozzle, and the airbag is compressed during grinding to remove dust from the rail surface; another example is a rail surface treatment device disclosed in the publication number CN210280057U, which uses a sprinkler to spray and clean dust.

[0004] The above-mentioned solutions respectively use the methods of blowing air and sprinkling water to clean the dust generated by rail surface treatment. However, in the method of blowing air with an airbag, the air blowing will stop during the restoration process of the airbag and there is a possibility of sucking dust into the airbag. Although sprinkling water can continuously clean the dust, it may cause the temperature of the rail surface after friction to drop rapidly, and cracks may be formed due to thermal expansion and contraction, posing certain potential safety hazards.

[0005] Therefore, we propose a rail surface treatment device for track construction to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to solve the problem that the method of blowing air to cool the rail surface with an airbag in the prior art cannot continuously blow air, and a rail surface treatment device for track construction is proposed.

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] By providing a rail surface treatment device for track construction in the embodiments of the present utility model, the problem that the existing method of blowing air on the rail surface with an airbag to cool it cannot continuously blow air is solved. By setting a fan driven by a gear rack, it is realized that the fan arranged on the processing seat can continuously blow air towards the rail when the processing seat moves to polish the rail surface, accelerating the cooling of the rail.

[0024] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0025] Refer to Figure 1 、 Figure 2 、 Figure 3 A rail surface treatment device for track construction includes a workbench 1, and two slide rails 2 are arranged on the workbench 1. The two slide rails 2 are parallel to each other and horizontally arranged. A processing seat 3 is slidably connected to the slide rails 2, and the processing seat 3 can slide back and forth along the slide rails 2. A grinding plate 4 is fixedly connected to the lower side of the processing seat 3. By driving the grinding plate 4 to move back and forth through the processing seat 3, the rail surface located below the grinding plate 4 is polished, thereby removing rust from the rail surface.

[0026] A plurality of rotating shafts 5 are rotatably connected to both sides of the processing seat 3 located at the grinding plate 4. The plurality of rotating shafts 5 are symmetrically distributed at both ends of the processing seat 3. One end of the rotating shaft 5 close to the workbench 1 is fixedly connected with a fan 6, and the rotation of the rotating shaft 5 can drive the fan 6 to rotate. The fan 6 is inclined and faces obliquely downward, and the fans 6 at both ends both face the middle, that is, directly below the grinding plate 4, so that when the fan 6 rotates, it can accelerate the air flow on the rail surface after being polished by the grinding plate 4, and further quickly cool the rail heated up after polishing, so as to avoid scalding the staff caused by the high-temperature rail after polishing as much as possible.

[0027] Refer to Figure 1 、 Figure 2 、 Figure 3 The other end of the rotating shaft 5 is fixedly connected with a gear 7, and the rotation of the gear 7 can drive the rotating shaft 5 to rotate. The workbench 1 is fixedly connected with racks 8 at both ends of the processing seat 3. The two racks 8 are parallel to each other and perpendicular to the rotating shaft 5. The racks 8 are meshed with the gears 7. When the rotating shaft 5 moves with the processing seat 3, it can drive the gear 7 to move along the rack 8, and then the gear 7 is driven to rotate and drive the rotating shaft 5 to rotate. A bearing is arranged between the processing seat 3 and the rotating shaft 5, and the bearing can reduce the friction when the rotating shaft 5 rotates, so that the fan 6 can rotate more conveniently and improve the cooling effect.

[0028] Reference Figure 1 , Figure 2 , Figure 4 There are two moving wheels 9 rotatably connected at both ends of the processing seat 3. The moving wheels 9 are rollingly connected to the workbench 1. The moving wheels 9 can reduce the friction when the processing seat 3 moves, so that the processing seat 3 can move back and forth more easily to grind the rails. The workbench 1 is provided with slide grooves 10 below both ends of the processing seat 3. The two slide grooves 10 are parallel to each other. The moving wheels 9 are located in the slide grooves 10. The moving wheels 9 are limited by the slide grooves 10 so that the moving wheels 9 can move along the slide grooves 10. The slide rail 2 is coated with lubricating oil. The provision of lubricating oil can further reduce the friction when the processing seat 3 moves.

[0029] Reference Figure 1 , Figure 3 , Figure 4 , both ends of the processing seat 3 are provided with limiting grooves 11, the limiting grooves 11 and the slide grooves 10 are parallel to each other and are located on the side of the processing seat 3, the workbench 1 is located in the limiting grooves 11 and fixedly connected with the limiting strips 12, the limiting strips 12 and the limiting grooves 11 are adapted to each other, and the limiting strips 12 are slidably connected with the processing seat 3, and the processing seat 3 is limited by the limiting strips 12 to minimize the up and down shaking of the processing seat 3 when moving, so as to ensure the fit between the grinding plate 4 and the surface of the rail. The workbench 1 is provided with a storage groove 13 directly below the grinding plate 4, and the dust generated by the grinding of the grinding plate 4 is collected through the storage groove 13 to facilitate subsequent cleaning.

[0030] Fixing bolts 14 are provided at both ends of the slide rail 2. The slide rail 2 can be detachably mounted on the workbench 1 by means of the fixing bolts 14. By using the fixing bolts 14 for installation and tightening, the slide rail 2 can be removed for maintenance and inspection.

[0031] Working principle: When in use, the processing seat 3 is moved so that the grinding plate 4 fixed under the processing seat 3 can grind the surface of the rail. At the same time, the movement of the processing seat 3 will drive the rotating shaft 5 to move, and the gear 7 fixed at the end of the rotating shaft 5 is meshed with the rack 8 on the workbench 1, so that the rotating shaft 5 moves and is driven by the gear 7 to rotate, thereby causing the fan 6 fixed at the other end of the rotating shaft 5 to rotate and speed up the air circulation speed on the surface of the rail facing the fan 6, so that the rail with too high temperature during the grinding process can be cooled down faster, and the high temperature rail can be avoided as much as possible to cause burns to the staff.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
