Detailed Implementation

[0018] like Figures 1-3 As shown, this utility model provides a technical solution: a medium-frequency steel shell furnace with a convenient cylinder replacement, including a support 1. A tilting plate 2 is hinged between the inner side walls of the support 1. A protective cylinder 3 is fixedly connected to the bottom surface of the tilting plate 2. A furnace body 4 is fixedly installed inside the protective cylinder 3. The tilting plate 2 can rotate around the hinge point with the support 1, driving the protective cylinder 3 and the furnace body 4 to tilt and rotate, facilitating the feeding of materials into the furnace body 4. The protective cylinder 3 encloses the furnace body 4, protecting it from damage caused by external factors. The furnace body 4 extends through and to the top of the tilting plate 2. A cover 41 is provided at the top of the furnace body 4. The furnace body 4 heats and melts materials such as metals through medium-frequency induction heating. The cover 41 can seal the top of the furnace body 4 to prevent heat loss during the melting process and to seal the furnace environment when necessary.

[0019] A cylinder assembly 5 is installed between the tilting plate 2 and the inclined wall of the support 1. The cylinder assembly 5 includes a first fixing seat 51 and a second fixing seat 52. The first fixing seat 51 is fixedly connected to the inclined wall of the support 1, and the second fixing seat 52 is fixedly connected to the side wall of the tilting plate 2. Sleeves 53 are hinged to the surface of the first fixing seat 51 and the bottom surface of the second fixing seat 52. A cylinder body 54 is inserted between the two sets of sleeves 53. A through hole is opened on the side wall of the sleeve 53, and a locking bolt 55 is threaded into the through hole. The first fixing seat 51 and the second fixing seat 52 provide the mounting base for the sleeve 53 and the cylinder body 54. The sleeve 53 can rotate relative to the cylinder body 54 by hinge and is inserted into the cylinder body 54 to provide installation positioning for the cylinder body 54. The cylinder body 54 can be easily replaced through the through hole in the side wall and the locking bolt 55.

[0020] A support assembly 6 is provided at the end of the bracket 1. The support assembly 6 includes a horizontal plate 61, which is fixedly connected to the end of the bracket 1. A groove 62 is provided on the surface of the horizontal plate 61. Two sets of symmetrically arranged movable seats 63 are slidably connected inside the groove 62. The horizontal plate 61 contacts the bottom surface to improve the stability of the bracket 1. The groove 62 provides a sliding track for the movable seats 63. The top of each set of movable seats 63 is hinged to a support plate 64. The top of the support plate 64 is hinged to a pad 65. The two sets of movable seats 63 are threadedly connected by a bidirectional threaded rod 66. By rotating the bidirectional threaded rod 66, the two sets of movable seats 63 can move relative to or away from each other, adjusting the support angle of the support plate 64 on the pad 65 and controlling the height of the pad 65 so that the pad 65 contacts the bottom surface of the protective cylinder 3, thereby supporting the flip plate 2 and raising the flip plate 2 for easy replacement of the cylinder body 54. A double-threaded rod 66 passes through and is rotatably connected to the end of the horizontal plate 61, and a rotating wheel 67 is fixedly connected to the end of the double-threaded rod 66. The rotating wheel 67 facilitates manual rotation of the double-threaded rod 66 by the operator and provides an operating force point for the rotation of the double-threaded rod 66.

[0021] In this utility model, when it is necessary to replace the cylinder body 54, first rotate the rotating wheel 67 to drive the bidirectional threaded rod 66 to rotate, so that the two sets of moving seats 63 move relative to each other. Adjust the support angle of the support plate 64 on the pad 65, control the height of the pad 65, so that the pad 65 contacts the bottom surface of the protective cylinder 3, thereby supporting the flip plate 2 and raising the flip plate 2 to make room for the replacement operation and facilitate the replacement of the cylinder body 54. At the same time, loosen the locking bolts 55 on the side wall of the sleeve 53, pull out the old cylinder body 54 from between the two sets of sleeves 53, insert the new cylinder body 54 and align it with the insertion hole of the sleeve 53, tighten the locking bolts 55 to fix it, rotate the rotating wheel 67 in the opposite direction, so that the two sets of moving seats 63 move in opposite directions, so that the height of the pad 65 is reduced, so that the cylinder body 54 can adjust the tilt angle of the furnace body 4 normally.

[0022] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
