Maintenance Procedures For Railway Bolts

Railway bolts are key components for connecting rails, and their safety and reliability are directly related to the safety and stability of railway transportation. In order to ensure the normal operation and service life of railway bolts, they must be properly operated and maintained. This article will introduce the safe operation and maintenance procedures for railway bolts to improve the safety level of railway transportation.

1. Basic Overview of Railway Bolts

Railway bolts are composed of screws and washers. The screws have two different heads, one is a square head for connecting rails; the other is a hexagonal head for tightening. There are two washers, one is a flat washer for connecting rails; the other is a wave washer for increasing elasticity and tightening force. There are many types of railway bolts, and the most common ones include M20, M22, M24, M27 and M30.

2.Operation procedures for railway bolts

(1). Check the status of railway bolts
Before using railway bolts, the status of the bolts and washers must be carefully checked to ensure that there are no damage, corrosion, deformation and other problems. If any problem is found, it must be replaced in time.
(2). Choose the correct bolts and washers
Depending on the connection parts and use environment, different specifications of railway bolts and washers need to be selected, and ensure that the materials of the bolts and washers meet the relevant standards.

(3). Use the right tools
When removing or installing railway bolts, you must use the right tools, such as hexagon wrenches, spanners, etc., and ensure that the quality and condition of the tools meet the requirements.

3.Maintenance procedures for railway bolts

(1). Regularly check the status of railway bolts
Regularly check the status of railway bolts, replace them in time if problems are found, and ensure their normal use.
(2). Prevent railway bolts from corrosion
Railway bolts are easily affected by air, moisture, pollutants, etc., and are prone to corrosion. Therefore, during the use of railway bolts, regular appearance cleaning and anti-corrosion treatment must be carried out.
(3). Keep railway bolts lubricated
The lubrication of railway bolts has an important impact on their service life. Therefore, during the use of railway bolts, they must be lubricated as required to maintain their long-term stable operation.
