Description

Technical Field

[0001] The invention belongs to the technical field of I-shaped rails, and in particular relates to an online processing method for an I-shaped rail port. Background Art

[0002] As we all know, I-shaped rails are widely used in the operation tracks of various equipment, especially in steel enterprises, and are widely used on large crane rails. This type of rail has become an indispensable part of industrial production due to its stable structure and strong bearing capacity. However, due to various factors (such as disrepair, frequent pressure, bumps, etc.), the crane rails of major steel mills across the country often have rail fracture problems. These problems not only affect the normal operation of the equipment, but also pose a threat to production safety. Once the rail breaks or the rail joint is damaged, usually only the emergency measure of temporarily adding the I-shaped rail head can be taken to restore the normal operation of the entire track. If not handled in time, it will seriously affect the production operation, and may even cause serious accidents such as production interruption due to rail problems. This situation is undoubtedly a huge challenge for modern steel companies that pursue high efficiency and continuous production. However, due to the continuity of production needs, crane equipment often cannot stop running, which makes it extremely difficult to deal with rail fractures. Moreover, traditional treatment methods are not only time-consuming and complicated, but also bring great challenges to on-site maintenance work. Maintenance personnel need to complete the repair work quickly and accurately while ensuring safety, which undoubtedly places higher demands on their skills and experience. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention provides an online processing method for an I-shaped rail port, aiming to solve the difficulty of online processing of rail fractures, while improving the strength and smooth transition of the fracture joints, effectively solving the problem of secondary damage to the fracture ends.

[0004] The technical solution adopted by the present invention is:

[0005] An online processing method for an I-shaped rail port, when the I-shaped rail port is damaged, the following steps are performed:

[0006] S1. According to the location of the damage and the horizontal depth D, grooves are cut on both sides of the I-shaped rail port, and the horizontal depth of the groove is not less than D;

[0007] S2. According to the size of the groove and the size of the side wall of the I-shaped track, the receiving connecting plates on both sides of the I-shaped track port are manufactured;

[0008] S3. Use fasteners to fix the I-shaped rail and the receiving connecting plate.

[0009] Preferably, the two grooves are symmetrically located on both sides of the I-shaped track.

[0010] Preferably, a standard gap and slope are left between the receiving connecting plate and the track.

[0011] Preferably, the range of the slope is 45° to 60°.

[0012] Preferably, the fastener is a bolt.

[0013] Preferably, the damage includes one or more of straight cracks, inclined cracks, surface pits, fragmentation on both sides of the fracture surface, surface fragmentation, and surface collapse.

[0014] Compared with the prior art, the advantages and positive effects of the present application are:

[0015] By implementing the above technical solutions, the present invention can effectively solve the problem of online processing of track fracture surfaces, not only significantly improving the strength at the fracture joint, but also greatly improving the smooth transition, thereby effectively solving the problem of secondary damage at the fracture end, and ensuring the stability and safety of the track.

[0016] The present invention not only solves the problem of track fracture connection, but more importantly, from the perspective of practical application, it successfully solves the problem of restoring track operation by processing the track online without stopping production. It effectively solves the related problems existing in direct connection ports, inclined connection ports, and adding track heads, simplifies the process flow and saves production time when urgently dealing with track fractures temporarily, fundamentally solves the problem that track maintenance cannot be carried out without stopping production of equipment, and thus improves production efficiency and economic benefits.

[0026] See also Figures 1 to 5 , an online processing method for an I-shaped rail port, when the I-shaped rail port is damaged, the following steps are performed:

[0027] S1. According to the location of the damage and the horizontal depth D, grooves 2 are cut on both sides of the I-shaped rail port 1, and the horizontal depth of the grooves is not less than D; horizontal refers to the direction from the outer edge of the I-shaped rail horizontally to the other side of the I-shaped rail;

[0028] S2. According to the size of the groove and the size of the side wall of the I-shaped track, the receiving connecting plates 3 on both sides of the I-shaped track port are manufactured;

[0029] S3. Use fasteners to securely connect the I-shaped rail and the receiving connecting plate.

[0030] The two grooves can be symmetrically located on both sides of the I-shaped rail.

[0031] A standard gap 4 and a slope are left between the receiving type connecting plate and the track. The slope ranges from 45° to 60°.

[0032] The fastener is a bolt.

[0033] The damage includes one or more of straight cracks, inclined cracks, surface pits, fragmentation on both sides of the fracture surface, surface fragmentation, and surface collapse.

[0034] In order to further understand the content, features and effects of the present invention, the following is a detailed description in conjunction with the accompanying drawings:

[0035] Current methods for dealing with the fracture surface of the track and existing problems:

[0036] The fracture surface types of the I-beam track are diverse, with straight cracks, inclined cracks, surface pits, fragmentation on both sides of the fracture surface, surface crumbling, surface collapse, and various defects mixed together. After the track fracture surface appears, when the crane equipment passes through, it will generate huge vibrations, causing various potential hazards due to the vibrations. In severe cases, the crane equipment cannot pass through the fracture surface position, seriously affecting production. Currently, the basic method for dealing with the fracture surface across the country is to cut the fracture surface position and then add a section of track. After cutting the track in this way, a blank space without track is formed, and at this time, equipment such as cranes cannot pass through. Often, production needs to be interrupted when dealing with the track; moreover, after adding the track, there are 2 ports and 4 cross-sections at one fracture surface position. After long-term operation, chipping will occur on all 4 port surfaces. In severe cases, the added track in the middle will be transversely fractured from the middle, resulting in a hollow state at the track port position, which is longer than the fracture surface without adding the track head, further restricting the safe passage of equipment. There are basically two treatment methods mentioned in the national and corresponding standards. One is to add a track head to a straight fracture surface, and the other is to add a track head to an inclined fracture surface. Generally, a 45° angle method and a telescopic overlapping track method are adopted.

[0037] The above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
