Description

Technical Field

[0002] Due to factors such as train crushing and edge compression, some bonded insulated rail ends have become damaged. Iron filings and foreign objects easily accumulate at the damaged areas, reducing the insulation resistance and affecting the normal use of the insulated joints. Damaged insulated joints are typically sealed with AB glue. The curing time of AB glue is significantly affected by temperature. Tests have shown that when the temperature is above 20℃, the curing time is less than 20 minutes, and when the temperature drops below 0℃, the curing time is more than 60 minutes, and problems such as glue runoff are also likely to occur (e.g., ...). Figure 4 (As shown). Meanwhile, to ensure normal train operation, the AB glue sealing and bonding insulation joint work must be carried out within the designated maintenance window, limiting the work time. This makes the time for repairing damaged AB glue bonding insulation joints even more pressing in winter. Therefore, a device is needed to provide heating and insulation for the glue application work on bonding insulation joints, in order to shorten the working time and improve work efficiency.

The lower end face of the heating end plate 2-2 is provided with a groove that mates with the track surface, and the upper end face of the heating end plate 2-2 is provided with a heating layer 2-3. The heating layer 2-3 is electrically connected to the battery holder 3-1 via a cable, and an insulation layer 2-4 is filled between the heating layer 2-3 and the partition 2-1. In use, the groove on the lower end face of the heating end plate 2-2 is placed on the track surface of the adhesive insulating joint, and the power supply component 3 provides power to heat the heating layer 2-3, providing a long-term heating function. The insulation layer 2-4 is made of flame-retardant insulation cotton with a thickness of at least 1 cm, providing insulation and preventing heat loss.

[0027] The partition 2-1 includes two side plates 2-1-1 and a top plate 2-1-2. In this embodiment, the side plates 2-1-1 and the top plate 2-1-2 are fixedly connected to the shell 1-1 by screws.

[0030] The procedure for applying adhesive to insulated joints in winter using this invention is as follows:

[0031] First, clean the rail ends by using an angle grinder, hacksaw, brush, etc., to remove the burrs and damaged insulation from the rail ends.

[0032] Second, sealing: Use tape to seal both sides of the rail head to prevent adhesive leakage;

[0033] 3. Repair with adhesive: Use AB glue to repair the damaged insulated rail ends;

[0034] Fourth, heating and insulation: Cover the groove on the lower end face of the heating end plate 2-2 with the rail seam of the insulating joint, connect the circuit, and use the temperature controller 4 to adjust the temperature. The heating layer 2-3 generates heat to heat the insulating joint, while the insulation layer 2-4 provides insulation.

[0035] 5. Grinding and Cleaning: Heat and maintain the temperature for approximately 30-40 minutes. Remove the device and check if the adhesive has cured. If it has cured, use an angle grinder to grind it, ensuring the adhesive conforms to the profile of the rail. After grinding, clean the insulating joint. If it has not cured, continue heating with the device until it cures. Finally, check that the adhesive strength meets the standard before ending the operation.
