Description

Technical Field

[0001] The utility model belongs to the technical field of rail maintenance tools, in particular to a hand-pushed railway curved rail grease coating and wear reduction trolley. Background Art

[0002] Due to the topography and layout of factory buildings, the railway lines laid by steel enterprises are mostly curved, and most have a radius of less than 150 meters. The wheelbase of the current locomotives is limited, resulting in greater friction between the curved rails and wheels, causing power loss and rapid wear of the rails and wheels. The current method to solve the wear problem of curves mostly relies on manual application of anti-friction agent. During the application process, it is easy to cause uneven application, causing the anti-friction agent to fall on the bottom of the rail, resulting in anti-friction agent waste and environmental pollution. If the anti-friction agent is not applied to the top surface of the rail, it will cause the locomotive wheels to slip, the wheels to spin, and damage the rails, which can seriously cause the rails to be scrapped.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] like Figure 1-2As shown, a hand-pushed railway curved rail 2 grease wear reduction trolley includes a base frame 1 and a rail 2. The base frame 1 is rollingly connected to the rail 2 through two running wheels 3 and two guide wheels 4 installed on the base frame 1. A push rod 5 is welded to the middle position of the base frame 1, and a handle 6 is welded to the top of the push rod 5. A button switch 7 is installed on the handle 6, and a grease gun 8 is installed on the push rod 5. A wire brush 9 and a scraper 10 are bolted to the base frame 1, and the button switch 7 is electrically connected to the grease gun 8.

[0023] The base frame 1 is an overall bow-shaped structure, with two running wheels 3 mounted horizontally and symmetrically at both ends of the base frame 1, and the two running wheels 3 are rollingly connected to the upper surface of the rail 2, and two guide wheels 4 are mounted vertically and symmetrically at both ends of the base frame 1, and the two guide wheels 4 are rollingly connected to the sides of the rail 2. The base frame 1 is designed in a bow shape so that the center of gravity of the base frame 1 is located in the center of the rail 2, thereby better controlling the center of gravity when pushing the utility model. If it is designed in a straight line, the center of gravity of the base frame 1 will be biased to one side of the rail 2, and the center of gravity of the entire device will need to be constantly adjusted when moving forward. If the force is uneven, it is easy to slip off the rail 2.

[0024] The running wheel 3 is a T-shaped single-sided wheel, and the wheel rim of the running wheel 3 and the guide wheel 4 are respectively located on both sides of the rail 2, so that a barrier can be formed on both sides of the rail 2 to prevent the utility model from falling off the rail 2.

[0025] A mounting plate 11 is welded to the middle of the arched structure of the chassis 1. A vertical plate 12 is welded to the mounting plate 11, and a pressure plate 13 is bolted to the vertical plate 12. A scraper 10 is positioned between the pressure plate 13 and the vertical plate 12. The bottom end of the scraper 10 has a notch that matches the shape of the greased surface of the rail 2. This greased surface is also the wear surface of the rail 2. This is where the wheels of rolling stock come into contact with the rail 2, causing wear and tear, and therefore requires the application of a friction-reducing agent. The scraper 10 can be made of a flexible rubber sheet, which prevents damage to the rail 2 during the scraping process and can be cut to size for easy replacement.

[0026] The push rod 5 has an inclined portion and a vertical portion. The top end of the inclined portion of the push rod 5 is welded to the handle 6, and the bottom end of the vertical portion of the push rod 5 is welded to the mounting plate 11. The push rod 5 is welded to the chassis 1 through the mounting plate 11.

[0027] Two clamps 14 are welded to the vertical portion of the push rod 5. The grease gun 8 is clamped to these clamps 14. The grease gun 8 is mounted on the push rod 5 via these clamps 14, with the oil outlet of the grease gun 8 bent toward the greased surface of the rail 2. The grease gun 8 is a common grease application tool. Lithium-powered grease guns 8 have their own batteries. Connecting the control circuit of the grease gun 8 to the push button switch 7 is a common technique and will not be discussed here. A rubber pad can be placed between the grease gun 8 and the clamps 14 to prevent damage to the surface of the grease gun 8.

[0028] An inclined plate 15 is welded to the chassis 1 , and a wire brush 9 is bolted to the inclined plate 15 . The wire end of the wire brush 9 abuts against the greased surface of the rail 2 .

[0029] The working principle of this utility model is:

[0030] When in use, the handle 6 is grasped and pushed forward, thereby moving the utility model forward on the rail 2 through the running wheel 3. The wheel flange of the running wheel 3 and the guide wheel 4 are located on both sides of the rail 2 to prevent the utility model from falling off the rail 2. At the same time, the wire brush 9 brushes the greased surface of the rail 2 to clean the debris thereon, thereby leaking out the rail 2 body to prevent the anti-friction agent from not adhering to the rail 2 and falling off.

[0031] As needed, the push button switch 7 is pressed during the forward movement, and the anti-friction agent falls from the oil outlet end of the grease gun 8 onto the rail 2. The scraper 10 applies the anti-friction agent so that the anti-friction agent is evenly coated on the greased surface of the rail 2.

[0032] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention.

[0033] The technology, shape and structure that are not described in detail in this utility model are all well-known technologies.
