Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0025] Online gluing refers to using a blocked window (a period of time without driving) on a normal driving railway line. The online gluing insulation joint is improved on the construction site for various adverse conditions, and the adverse conditions mainly include the gap between the two ends of the rail of the gluing insulation joint and the insulation plate caused by insufficient sawing rail perpendicularity and the like, which affects the service life of the gluing insulation joint, as shown in Figure 4 、 Figure 5 、 Figure 6 and Figure 7 . Figure 4 Fig. 1 is a schematic view of a normal state of gluing insulation, Figure 5 Fig. 2 is a schematic view of an abnormal state of gluing insulation Figure 1 , Figure 6 Fig. 3 is a schematic view of an abnormal state of gluing insulation Figure 2 , Figure 7 Fig. 4 is a schematic view of an abnormal state of gluing insulation Figure 3 .

[0026] At present, end grinding machines are commonly used for grinding to eliminate the problem of uneven rail end faces, but in most cases on site, the rail end grinding work cannot be carried out due to time constraints or difficulty in taking out the rail, so the use of end grinding machines for grinding has great limitations in on-site implementation.

[0027] The online gluing insulation is shown in Figure 5 、 Figure 6 and Figure 7 , and there will be irregular gaps at both ends of the gluing insulation plate, so the scheme of the present application is designed to improve the online gluing insulation joint.

[0028] According to the embodiments of the present application, a gap adjustment method for an online gluing insulation joint is provided, and a flowchart of an embodiment of the method of the present application is shown in Figure 1 . The gap adjustment method for the online gluing insulation joint is applied to the insulation gluing at the end faces of a first rail and a second rail; the gap adjustment method for the online gluing insulation joint comprises steps S110 to S140.

[0029] At step S110, the size of the end face of the first rail is acquired, the size of the end face of the second rail is acquired, and the gap between the end face of the first rail and the end face of the second rail is acquired.

[0030] In some embodiments, the size of the end face of the first rail and the size of the end face of the second rail include: the top face distance of the two rail ends, the left and right side distance, the web distance, the left rail bottom distance, and the right rail bottom distance.

[0031] At step S120, according to the size of the end face of the first rail and the size of the end face of the second rail, an irregular structure formed by the end face of the first rail and the end face of the second rail is determined.

[0032] At step S130, according to the irregular structure, a filling insulation plate is made and gluing is implemented.

[0033] In some embodiments, the required gluing insulation clamping plate at the end face of the first rail is a first gluing insulation clamping plate, the required gluing insulation clamping plate at the end face of the second rail is a second gluing insulation clamping plate, and the first gluing insulation clamping plate and the second gluing insulation clamping plate have a basic insulation end plate therebetween.

[0034] The specific process of making the filling insulation plate and implementing the gluing according to the irregular structure in step S120 is described in the following exemplary description.

[0035] The following will be described in combination with Figure 2 The flowchart of an embodiment of making the filling insulation plate and implementing the gluing in the method of the present application is shown in the accompanying drawings, which further illustrates the specific process of making the filling insulation plate and implementing the gluing in step S130, including steps S210 to S230.

[0036] At step S210, according to the irregular structure, an irregular insulation end plate made of the same material as the basic insulation end plate is made.

[0037] At step S220, according to the size of the irregular structure, the orientation, position, cutting line, and cutting thickness of the irregular insulation end plate are calibrated, and the calibration is cut to obtain the required insulation end plate, which is recorded as the filling insulation plate (i.e. Figure 8 the filling part shown in the accompanying drawings).

[0038] At step S230, the filling insulation plate and the basic insulation end plate are glued to form an adjusted insulation end plate.

[0039] At step S140, according to 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 face of the first rail and the end face of the second rail, the bolt holes required for bonding the end face of the first rail and the end face of the second rail are determined and the bonding is achieved.

[0040] The scheme of the present application provides a method for adjusting the gap of the insulation end plate of the online bonding insulation joint, aiming to eliminate the gap between the insulation end plates, meet the design needs of the field installation, and solve the problem of the gap between the insulation plate and the end face of the rail caused by the deviation of the verticality of the rail section due to the sawing operation of the rail during the online bonding insulation joint process. In the scheme of the present application, irregular-shaped insulation plates are made for the gap problem to ensure 100% filling of the gap; and for individual gaps, the problem of size change of the bolt hole during the bonding process is eliminated by re-drilling.

[0041] In some embodiments, the specific process of determining the bolt holes required for bonding the end face of the first rail and the end face of the second rail according to 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 face of the first rail and the end face of the second rail in step S140 is described in the following exemplary description.

[0042] The following will be described in conjunction with Figure 3 The following will be described in conjunction with

[0043] At step S310, according to 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 face of the first rail and the end face of the second rail, the bolt holes of the first bonding insulation clamp plate and the bolt holes of the second bonding insulation clamp plate are determined.

[0044] At step S320, the first bonding insulation clamp plate, the adjusting insulation end plate, and the second bonding insulation clamp plate are bonded through the bolt holes of the first bonding insulation clamp plate and the bolt holes of the second bonding insulation clamp plate, the gap between the base insulation end plate and the first bonding insulation clamp plate or the second bonding insulation clamp plate is eliminated, and the required online bonding insulation joint is formed.

[0045] In some embodiments, in the process of determining the bolt holes of the first bonding insulation clamp plate and the bolt holes of the second bonding insulation clamp plate in step S310, the most protruding position of the end face of the first rail and the end face of the second rail is aligned and drilled as the alignment point.

[0046] Specifically, the present invention provides a method for adjusting the gap between the insulating end plates of an online adhesive-bonded insulating joint, mainly including:

[0047] Step 1: Fabricate special insulating end plates based on the irregular structure formed by the two rail end faces;

[0048] In step 1, the dimensions of the irregular surface are determined by measuring the top surface distance, left and right edge distance, web distance, left rail bottom distance, and right rail bottom distance of the two rail ends. The cutting line is marked based on the measured data of the irregular surface dimensions, and the cutting thickness is marked. It should be noted that the orientation and position of the filler need to be marked. Then, the insulating end plate is cut using a precision grinding machine.

[0049] Figure 9 This is a schematic diagram illustrating the method for measuring the dimensions of the two rail end faces, as shown below. Figure 9 The diagram shows the three-dimensional structure of the two rail end faces. The dimensions of the two rail end faces include: top surface distance h1, left and right edge distance h2, web distance h3, left rail bottom distance h4, and right rail bottom distance h5. Cutting lines are calibrated using measured data of the irregular surface dimensions, and the cutting thickness is determined. For example, during the measurement of the two rail end faces, if the left rail bottom distance is measured to be 10mm, the right rail bottom distance to be 8mm, and the top and web distances to be 8mm, then a filler plate is fabricated on a 6mm thick insulating board. Specifically, as shown... Figure 10 As shown, Figure 10 This is a schematic diagram showing the dimensions of the two rail end faces.

[0050] exist Figure 10 In the example shown, the insulation plates on the left and right rail end faces are bonded together using adhesive. The insulation plate on the left rail end face has an irregular structure, with a thickness of 4mm on the left and 2mm on the right, the change from 2mm to 4mm following a linear function relationship; specifically, it is a linearly increasing relationship. The thickness of the insulation plate at the top of the left rail end face is 2mm. The insulation plate on the right rail end face has a straight structure, with a thickness of 6mm on the left, right, and top of the right rail end face.

[0051] Step 2: Based on the gap and dimensions of the rail end faces, redesign and drill the bolt holes required for bonding.

[0052] In step 2, the end gap of the rail is measured. There are two cases here: the first case is as follows... Figure 5 In the case shown, the clearance profile edge can be measured to determine the size, and a hole can be drilled to align the 0-degree line with the edge of the rail head; the second case is as follows... Figure 7In the case shown, the measurement gap method is the same as the punching, and the rail bottom edge needs to be aligned before punching.

[0053] Figure 8 The schematic diagram of the insulating filling state is shown in FIG. Figure 8 Figure 8 The blue part in the figure is the original insulating plate, which has the structure of equal width in the up-down and left-right directions; the red part is the filling structure, which has a shape determined by the site condition, and the material used is the same as that of the blue insulating plate. After the production is completed, the blue insulating plate is glued, and then filled into the gap.

[0054] The steel rail drilling needs to be strictly controlled in size so that the clamp plate can be normally installed. When the perpendicularity of the rail end surface is insufficient, the previous drilling method cannot be used, and the previous rail head alignment caliper method cannot be used. Instead, the most protruding position of the end surface is used as the alignment point for alignment. In this way, drilling is performed, and subsequent gluing of the clamp plate and bolt installation can be performed, thereby ensuring the normal installation of the gluing clamp plate.

[0055] The scheme of the present application solves the problem of insulating plate separation caused by insufficient perpendicularity of the sawn steel rail, improves the quality and success rate of the glued insulation, overcomes the problem of insulating plate separation caused by the deviation of the steel rail section during the on-site operation, eliminates the separation, improves the service life of the insulation, has good on-site operability, and is suitable for more adverse working conditions. It can be operated without removing the steel rail.

[0056] By adopting the technical scheme of the embodiment, the top surface distance, left and right edge distance, abdominal distance, left rail bottom distance and right rail bottom distance of the two rail end portions are measured for the separation between the insulating end plates of the online glued insulation joint, the irregular surface size is determined to make the irregular shape of the insulating plate, the orientation, position, cutting line and cutting thickness of the insulating plate are calibrated according to the irregular size, the insulating end plate needed is obtained by cutting the insulating plate according to the calibration, and the original insulating plate is glued. According to the rail end surface gap and size, the bolt hole required for gluing is redesigned and punched, and the bolt is used for gluing to complete the separation adjustment of the online glued insulation joint, so that the separation between the insulating end plates is ensured.

[0057] According to the embodiment of the present application, an online glued insulation joint corresponding to the separation adjustment method of the online glued insulation joint is also provided. The online glued insulation joint is obtained by the above-mentioned separation adjustment method of the online glued insulation joint.

[0058] Since the processing and functions realized by the online glued insulation joint of the embodiment basically correspond to the embodiments, principles and examples of the foregoing method, the description of the embodiment is not described in detail, and the relevant description in the foregoing embodiments can be referred to, which is not described herein.

[0059] ​In summary, the person skilled in the art can easily understand that the above-mentioned advantageous modes can be freely combined and superimposed without conflict.

[0060] The above merely provides an example of the present application, and is not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of claims of the present application.
