DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings.

[0016] Online bonding refers to the use of blocking windows (a period of time when no traffic is allowed) on a railway line with normal traffic. Online bonding insulation joints are improved at the construction site for various adverse working conditions. The adverse working conditions mainly include the gap between the ends of the rails and the insulation board caused by insufficient verticality of the sawed rails, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, it affects the service life of the glued insulating joint. Figure 4 This is a schematic diagram of the normal state of bonded insulation. Figure 5 This is a diagram showing abnormal state of bonded insulation.

[0017] At present, end grinders are often used to grind rails to eliminate uneven rail end faces. However, in most cases on site, rail end grinding cannot be performed due to time constraints or when the rails are difficult to remove. Therefore, the use of end grinders for grinding on site has great limitations.

[0018] Wire bonding insulation Figure 5 , Figure 6 and Figure 7 As shown, there are irregular gaps at both ends of the glued insulating plates. Therefore, the solution of the present invention is designed to improve the on-line glued insulating joints.

[0019] According to an embodiment of the present invention, a method for adjusting the gap of an online adhesively bonded insulating joint is provided, such as Figure 1 The flow chart of an embodiment of the method of the present invention is shown. The gap adjustment method of the online glued insulating joint is applied to the insulation glue joint at the end surface of the first rail and the end surface of the second rail; the gap adjustment method of the online glued insulating joint comprises: steps S110 to S140.

[0020] In step S110, the size of the end surface of the first rail is obtained, the size of the end surface of the second rail is obtained, and the gap between the end surface of the first rail and the end surface of the second rail is obtained.

[0021] In some embodiments, the size of the end face of the first rail and the size of any end face of the second rail include: the size of the top surface, the size of the belly, the left rail bottom distance, and the right rail bottom distance of any end face.

[0022] In step S120, the irregular structure formed by the end surface of the first rail and the end surface of the second rail is determined according to the size of the end surface of the first rail and the size of the end surface of the second rail.

[0023] In step S130, a filling insulation board is manufactured and glued according to the irregular structure.

[0024] In some embodiments, the glued insulating splint required at the end face of the first rail is a first glued insulating splint, and the glued insulating splint required at the end face of the second rail is a second glued insulating splint, and a basic insulating end plate is provided between the first glued insulating splint and the second glued insulating splint.

[0025] The specific process of manufacturing the filling insulation board and gluing it according to the irregular structure in step S120 is described in the following exemplary embodiment.

[0026] Combine the following Figure 2 The schematic flow chart of an embodiment of manufacturing a filling insulation board and gluing it in the method of the present invention further illustrates the specific process of manufacturing a filling insulation board and gluing it in step S130, including: step S210 to step S230.

[0027] Step S210: manufacturing an irregular insulating end plate made of the same material as the basic insulating end plate according to the irregular structure.

[0028] Step S220, according to the size of the irregular structure, the orientation, position, cutting line, and cutting thickness of the irregular insulating end plate are calibrated, and the required insulating end plate is obtained by cutting according to the calibration, which is recorded as the filling insulating plate (i.e. Figure 8 Filled section shown).

[0029] Step S230: gluing the filling insulation plate to the basic insulation end plate to form an adjusted insulation end plate.

[0030] In step S140, the bolt holes required for gluing the end faces of the first rail and the second rail are determined and the gluing is achieved based on the size of the end face of the first rail, the size of the end face of the second rail, and the gap between the end faces of the first rail and the second rail.

[0031] The solution of the present invention provides a method for adjusting the gap between the insulating end plates of the online glued insulating joint, which aims to eliminate the gap between the insulating end plates and is designed to meet the needs of on-site installation, and is used to solve the gap problem between the insulating plate and the end face of the rail caused by the verticality deviation of the rail section caused by the sawing operation of the rail during the process of online glued insulating joints. In the solution of the present invention, an insulating plate of irregular shape is made to solve the gap problem, ensuring that the gap is 100% filled; for individual gaps, the problem of bolt hole size changes during the gluing process is eliminated by re-drilling.

[0032] In some embodiments, in step S140, the bolt holes required for gluing the end faces of the first rail and the second rail are determined based on the size of the end face of the first rail, the size of the end face of the second rail, and the gap between the end faces of the first rail and the second rail, and the specific process of implementing the gluing is described in the following exemplary embodiment.

[0033] Combine the following Figure 3 The schematic flow chart of an embodiment of determining the bolt holes required for gluing the end faces of the first rail and the second rail and realizing the gluing in the method of the present invention further illustrates the specific process of determining the bolt holes required for gluing the end faces of the first rail and the second rail and realizing the gluing in step S140, including: step S310 to step S320.

[0034] Step S310, determining the bolt holes of the first adhesive insulating clamping plate and the bolt holes of the second adhesive insulating clamping plate according to the size of the end surface of the first rail, the size of the end surface of the second rail, and the gap between the end surfaces of the first rail and the second rail.

[0035] Step S320, glueing the first glued insulating splint, the adjustment insulating end plate, and the second glued insulating splint together through the bolt holes of the first glued insulating splint and the bolt holes of the second glued insulating splint, eliminating the gap between the basic insulating end plate and the first glued insulating splint or the second glued insulating splint, and forming the required online glued insulating joint.

[0036] In some embodiments, in the process of determining the bolt holes of the first adhesively bonded insulating clamp and the bolt holes of the second adhesively bonded insulating clamp in step S310, the most protruding positions of the end faces of the first rail and the second rail are used as alignment points for alignment and drilling.

[0037] Specifically, the solution of the present invention provides a method for adjusting the gap between the insulating end plates of the in-line adhesively bonded insulating joint, which mainly includes: Step 1: Making a special insulating end plate according to the irregular structural surface formed by the end faces of the two rails; In step 1, the irregular surface size is determined by measuring the top surface distance, left and right margin distances, belly distance, left rail bottom distance, and right rail bottom distance of the two rail ends; the cutting line is calibrated according to the measured data of the irregular surface size, and the cutting thickness size is calibrated. It should be noted that the filling parts need to be marked with the direction and position, and then the insulating end plate is cut using a fine grinder.

[0038] Fig. 9 The diagram is a schematic diagram of the dimension measurement method of the two rail end faces, such as Fig. 9 The figure shows the three-dimensional structure of the two rail end faces. The dimensions of the two rail end faces include: the top surface distance h1, the left and right margins h2, the belly distance h3, the left rail bottom distance h4, and the right rail bottom distance h5. The cutting line calibration is done through the measured data of the irregular surface dimensions, and the cutting thickness dimension is calibrated. For example, in the process of measuring the dimensions of the two rail end faces, the left rail bottom distance is measured to be 10mm, the right rail bottom distance is 8mm, and the top surface distance and belly distance are both 8mm. Then, a filling plate is made on the basis of a 6mm insulation board (i.e., an insulation board with a thickness of 6mm). Specifically, Fig.10 As shown, Fig.10 Schematic diagram of the dimensions of the two rail end faces.

[0039] exist Fig.10 In the example shown, the insulating plates on the left rail end face and the right rail end face are bonded with adhesive. The insulating plate on the left rail end face is an irregular structure, the thickness of the insulating plate on the left rail end face is 4mm on the left side and 2mm on the right side, and the variation relationship between 2mm and 4mm is a linear function relationship, specifically a linear increasing relationship; the rail top thickness of the insulating plate on the left rail end face is 2mm. The insulating plate on the right rail end face is a straight structure, and the thickness of the left side, the right side, and the rail top thickness of the insulating plate on the right rail end face are all 6mm.

[0040] Step 2: Redesign and drill the bolt holes required for bonding according to the gap and size of the rail end faces.

[0041] In step 2, the end gap of the rail is measured. There are two cases: the first case is as follows: Figure 5 In the case shown, the gap profile edge can be measured to determine the size, and then the 0 degree line can be aligned with the edge of the rail head by drilling; the second case is as follows Figure 7 In the situation shown, the method of measuring the gap is the same. When drilling, the bottom edge of the rail must be aligned before drilling.

[0042] Figure 8 This is a schematic diagram of the bonding insulation filling state. Figure 8 As shown in Figure 8The blue part in the middle is the original insulation board, which has the same width up and down and left and right. The red part is the filling structure, the shape of which depends on the on-site conditions. It is made of the same material as the blue insulation board. After production, it is glued to the blue insulation board and then filled into the gap.

[0043] The size of the rail holes must be strictly controlled to ensure the normal installation of the splint. When the verticality of the rail end face is insufficient, the previous drilling method must be abandoned. The previous rail head alignment caliper method must not be used. Instead, the most protruding position of the end face must be used as the alignment point. Only by drilling in this way can the subsequent glued splint bolts be installed, thereby ensuring the normal installation of the glued splint.

[0044] The solution of the present invention solves the problem of insulation board separation caused by insufficient verticality of the rails due to sawing, and improves the quality and success rate of adhesive insulation; overcomes the problem of insulation board separation caused by rail section deviation during on-site operations, eliminates separation, and improves the service life of insulation, has good on-site operability, is suitable for more adverse working conditions, and can be operated without removing the rails.

[0045] By adopting the technical solution of this embodiment, the distance between the insulating end plates of the online glued insulating joint is measured, and the top surface distance, left and right margins, belly distance, left rail bottom distance and right rail bottom distance of the two rail ends are measured to determine the size of the irregular surface and make an insulating plate of irregular shape; the orientation, position, cutting line and cutting thickness of the insulating plate are calibrated according to the irregular size, and the insulating plate produced according to the calibration cutting is obtained to obtain the required insulating end plate, which is glued with the original insulating plate; according to the gap and size of the rail end faces, the bolt holes required for gluing are redesigned and punched, and gluing is performed using bolts to complete the adjustment of the gap between the online glued insulating joints to ensure that there is no gap between the insulating end plates.

[0046] According to an embodiment of the present invention, an online glued insulating joint corresponding to the gap adjustment method of the online glued insulating joint is also provided. The online glued insulating joint is obtained by the gap adjustment method of the online glued insulating joint described above.
