Description

Technical Field

[0001] This utility model relates to the technical field of integral induction heating device for support rollers, and in particular to an integral induction heating device for support rollers. Background Technology

[0002] The roller induction heating device utilizes the principle of electromagnetic induction to convert electrical energy into heat energy, thereby heating the rollers used in excavators. This heating method involves passing an alternating current through an induction coil to generate an alternating magnetic field, which in turn induces eddy currents inside the roller. These eddy currents are converted into heat energy through the resistance inside the roller, causing the roller to be heated as a whole or in a localized area.

[0003] When using an induction heating machine to heat the surface of a roller in excavators, traditional induction heating machines involve directly mounting the roller onto the outer surface of a hollow rod on one side of a sliding frame. Then, the first electric telescopic rod is activated, causing the sliding frame to slide to a certain position within the top inner wall of the induction heating machine, transporting the roller into the induction coil. The induction coil is then energized to heat the roller. Since the diameter of the hollow rod used to fix the roller is usually fixed, when the induction heating machine needs to heat rollers with different inner diameters, a matching hollow rod must be replaced for positioning. This results in low applicability and inconvenience for traditional induction heating machines. Utility Model Content

[0020] Example 1, as Figure 1-4As shown, an integral induction heating device for a support roller includes a support roller induction heater 1. An induction coil 4 is provided on one side of the support roller induction heater 1. A first electric telescopic rod 5 is fixedly connected to one side of the top inner wall of the support roller induction heater 1. A sliding frame 6 is fixedly connected to one side of the output rod of the first electric telescopic rod 5. An adjustment limiting device 2 is provided on one side of the sliding frame 6. The adjustment limiting device 2 includes a hollow rod 21 and several limiting plates 25. A replacement device 3 is provided between one end of the hollow rod 21 and one side of the sliding frame 6. Several sliding holes 22 are opened on the outer surface of one end of the hollow rod 21. A second electric telescopic rod 23 is fixedly connected to one side of the inner wall of the hollow rod 21. A groove block 24 is fixedly connected to the output rod of the second electric telescopic rod 23. The outer surface of the groove block 24 is slidably connected to the inner wall of the hollow rod 21. A connecting rod 26 is rotatably connected to the inner wall of the groove block 24 and the sliding hole 22. One end of the connecting rod 26 is rotatably connected to one side inner wall of the limiting plate 25. The connecting rod 26 is slidably connected to the sliding hole 22. When using the roller induction heating machine 1 to heat the surface of the roller in the field of excavators, the roller can be sleeved on the outer surface of several limiting plates 25. Then, the second electric telescopic rod 23 inside the hollow rod 21 is activated to drive the groove block 24 to slide to one end in the inner wall of the hollow rod 21. This pushes the connecting rod 26 to rotate to a certain angle in the groove block 24, the sliding hole 22, and the inner wall of the limiting plate 25, while sliding to one end, pushing the limiting plate 25 to open outward and supporting and limiting the inner wall of the roller. By adjusting the several limiting plates 25, the hollow rod 21 can provide internal support and limit for various rollers with different inner diameters, improving the applicability of the roller induction heating machine 1 and making it convenient to use. During heating processing, the first electric telescopic rod 5 can be activated to drive the sliding frame 6 to slide to a certain position in the top inner wall of the roller induction heating machine 1, transporting the roller to the inside of the induction coil 4. Then, the induction coil 4 is energized to heat the roller.

[0021] Reference Figure 2 and Figure 3 As shown, this embodiment discloses that bearings 27 are fixedly connected to both ends of the connecting rod 26, and the outer rings of several bearings 27 are fixedly connected to the inner walls of the groove block 24, the limiting plate 25, and the sliding hole 22. By setting the bearings 27, the rotational wear between the connecting rod 26 and the groove block 24, the limiting plate 25, and the sliding hole 22 can be reduced, facilitating the rotation of the connecting rod 26. Several anti-slip blocks 28 are fixedly connected to one side of the limiting plate 25, and the anti-slip blocks 28 are arranged at equal intervals. By setting the anti-slip blocks 28, the contact friction on one side of the limiting plate 25 can be increased, so that it can be supported and fixed to the inner wall of the support roller, and the positioning can be more firmly and stably limited.

[0022] Reference Figure 2 and Figure 3As shown in the figure, this embodiment discloses that a plurality of reinforcing rods 29 are fixedly connected to the outer surface of one end of the output rod of the second electric telescopic rod 23, and one side of the reinforcing rod 29 is fixedly connected to one side of the groove block 24. By setting the reinforcing rods 29, the connection area between the output rod of the second electric telescopic rod 23 and the groove block 24 can be increased, making the connection less prone to breakage and damage.

[0023] Reference Figure 4 As shown, this embodiment discloses a replacement device 3 including a circular block 31. One side of the circular block 31 is fixedly connected to one side of the sliding frame 6. A first slot 32 is symmetrically opened on one side of the circular block 31. A second slot 33 is opened on both sides of the inner wall of the first slot 32. One end of the hollow rod 21 is inserted into the inner wall of the circular block 31. A locking block 34 is slidably connected to the inner walls on both sides of one end of the hollow rod 21. A spring 35 is sleeved and connected to the outer surface of one end of the locking block 34. The two ends of the spring 35 are fixedly connected to the outer surface of one end of the hollow rod 21 and one side of the locking block 34, respectively. The two ends of the locking block 34 and the spring 35 are respectively inserted into the interior of the second slot 33 and the first slot 32. When the hollow rod 21 is damaged and needs to be replaced, the locking block 34 can be manually held and pulled to one end of the inner wall of the hollow rod 21 to a certain position, which will stretch the spring 35 and pull it out of the second locking groove 33. Then, the locking block 34 and the hollow rod 21 can be pulled away from the sliding frame 6, so that the hollow rod 21 and the locking block 34 can be pulled out from the inner wall of the ring block 31 and the first locking groove 32 respectively, thereby removing the hollow rod 21 from the sliding frame 6 for easy replacement. Similarly, a new hollow rod 21 can be installed, which can also facilitate maintenance and storage, and facilitate the use of the roller induction heating machine 1.

[0024] Reference Figure 4 As shown, this embodiment discloses a rectangular hole 36 on one side of the locking block 34, located at the end of the locking block 34 away from the hollow rod 21. By providing the rectangular hole 36, when operation is required, one side of the locking block 34 can be easily manually engaged, facilitating its removal from the inner wall of the hollow rod 21. Rectangular grooves 38 are symmetrically provided on the inner wall of the annular block 31. Rectangular blocks 37 are symmetrically fixed to the outer surface of one end of the hollow rod 21, and are inserted into the interior of the rectangular grooves 38. By providing the rectangular blocks 37 and rectangular grooves 38, one end of the hollow rod 21 can be secondary-limited, preventing it from rotating after being installed in the inner wall of the annular block 31. Several limiting blocks 39 are symmetrically fixed to one side of the annular block 31, and are inclinedly fixed on both sides of the entrance to the first locking groove 32. By setting the limiting block 39, the area at the entrance of the first slot 32 can be increased, making it easier for the locking block 34 on the hollow rod 21 to be quickly aligned, thus facilitating the installation of the hollow rod 21.
