[0015] Beneficial effects:

[0016] When the fireproof door with a window of the present invention moves between the material area and the electrolytic cell, the driving motor fixedly installed on the outer wall of the gantry is started. The output end of the driving motor will drive the worm to rotate. Since a worm gear is meshed on the outer side of the worm, the worm gear and the transmission shaft inside the worm gear are driven to rotate. Oppositely-directed first bevel gears are fixedly connected to both ends of the transmission shaft. Second bevel gears with the same direction are meshed on the outer sides of the two first bevel gears, so as to drive the two transmission lead screws to move in opposite directions. Because the thread directions of the two transmission lead screws are opposite, the guide seat can be stably driven to move along the guide rail by the two transmission lead screws under the action of the lead screw nuts. Moreover, a driving hydraulic cylinder is fixedly installed on the top of the guide seat. The output end of the driving hydraulic cylinder is fixedly connected to a mounting frame. A hanging mechanism is arranged on the mounting frame, so that the output end of the driving hydraulic cylinder can drive the hanging mechanism on the mounting frame to suspend the fireproof door with a window. Subsequently, under the drive of the moving mechanism, the guide seat will drive the fireproof door with a window below to move, so that the fireproof door with a window can stably move between the material area and the electrolytic cell, facilitating the fireproof door with a window to move above the electrolytic cell. Then, the output end of the driving hydraulic cylinder will send the fireproof door with a window into the electrolytic cell for electroplating processing. In addition, the transmission mode of the worm gear and the worm has a self-locking function, which can limit the position of the guide seat staying at the processing position, so that the fireproof door with a window below the guide seat can stably stay in the electrolytic cell for electroplating processing.

[0017] When the present invention is hanging a fire door with a window, the first electric cylinder fixedly installed on the outer wall of the first fixing frame is activated, so that the output end of the first electric cylinder will drive the first clamping plate to fit and press against the first outer surface of the fire door with a window. The second electric cylinder fixedly installed on the outer wall of the second fixing frame is activated, so that the output end of the second electric cylinder will drive the second clamping plate to fit and press against the second outer surface of the fire door with a window, so that the fire door with a window is fixedly hung up under the combined extrusion of the first clamping plate and the second clamping plate. After the fire door with a window is fixedly hung up under the combined extrusion of the first clamping plate and the second clamping plate, the third electric cylinder on the first moving frame is activated, so that the output end of the third electric cylinder will drive the third clamping plate to fit and press against the first inner surface of the fire door with a window. The fourth electric cylinder fixedly installed on the outer wall of the second moving frame is activated, so that the output end of the fourth electric cylinder will drive the fourth clamping plate to fit and press against the second inner surface of the fire door with a window, increasing the grasping points of the fire door with a window and improving the grasping force of the fire door with a window at the window installation groove, so that the fire door with a window is firmly fixed under the combined action of the first clamping plate, the second clamping plate, the third clamping plate and the fourth clamping plate. The fire door with a window can be firmly hung in the electrolytic cell for electroplating operation, improving the electroplating effect of the fire door with a window.

[0018] When the present invention is grasping fire doors with windows at different positions of the window installation groove, first, the moving mechanism will drive the guide seat to move above the window installation groove. Subsequently, the output end of the seventh electric cylinder will drive the first moving frame to slide in the sliding groove and move to the outside of the first inner surface. The output end of the sixth electric cylinder will drive the second moving frame to slide in the sliding groove and move to the outside of the second inner surface, so that the third clamping plate below the first moving frame and the fourth clamping plate below the second moving frame can be positioned outside the first inner surface and the second inner surface. Finally, driving the first clamping plate, the second clamping plate, the third clamping plate and the fourth clamping plate can grasp fire doors with windows at different positions of the window installation groove.

[0019] When the fire door with a window is firmly fixed under the combined action of the first clamping plate, the second clamping plate, the third clamping plate and the fourth clamping plate, the first clamping plate, the second clamping plate, the third clamping plate and the fourth clamping plate are distributed on one side of the fire door with a window close to the window installation groove. At this time, start the seventh electric cylinder on the first fixing frame, so that the first L-shaped bracket slides in the first guiding groove and drives the fifth clamping plate to move to the symmetric side of the first clamping plate. Then start the eighth electric cylinder on the first L-shaped bracket, so that the fifth clamping plate fits and presses against the first outer surface. Similarly, start the ninth electric cylinder on the second fixing frame, so that the second L-shaped bracket slides in the second guiding groove and drives the sixth clamping plate to move to the symmetric side of the second clamping plate. Then start the tenth electric cylinder on the second L-shaped bracket, so that the sixth clamping plate fits and presses against the second outer surface. In the above way, the fifth clamping plate and the sixth clamping plate can clamp and fix the side of the fire door with a window far from the window installation groove. The first clamping plate, the second clamping plate, the fifth clamping plate and the sixth clamping plate are evenly distributed around the fire door with a window. Therefore, the stability of grasping the fire door with a window can be effectively improved.

[0044] The present invention provides an insulating hanging device for electroplating a steel fire door as shown in Figures 1-9 Figure 1, which includes a hanging plate 1. The bottom of the hanging plate 1 is fixedly connected to a gantry 3 through a connecting plate 2. Guide rails 4 are arranged on both sides of the gantry 3. A guide seat 5 is slidably connected to the outside of the guide rails 4. A moving mechanism 6 is arranged inside the gantry 3. A driving hydraulic cylinder 7 is fixedly installed on the top of the guide seat 5. The output end of the driving hydraulic cylinder 7 is fixedly connected to a mounting frame 8. A hanging mechanism 9 is arranged below the mounting frame 8. A stabilizing mechanism 11 is arranged on the hanging mechanism 9. A fire door with a window 12 is arranged below the hanging mechanism 9. The fire door with a window 12 includes a first outer surface 1201 and a second outer surface 1202 on the outside, and a first inner surface 1203 and a second inner surface 1204 at the window mounting groove 1205. The surface of the present invention can be coated with an insulating material, and coating the insulating material can effectively isolate the current, ensuring that the electroplating process only occurs on the surface of the workpiece, and avoiding the problem of uneven electroplating caused by the current passing through the fixture. In addition, the insulating material can also protect the fixture from being corroded by the electroplating solution and extend its service life.

[0045] In the embodiment, refer to Figures 3-4, in order to enable the fire door with window 12 to move stably between the material area and the electrolytic cell, the moving mechanism 6 includes two driving lead screws 607 rotatably connected to the inner side of the gantry 3. The thread directions of the two driving lead screws 607 are opposite. A lead screw nut 608 is arranged on the outer side of the driving lead screw 607, and the lead screw nut 608 is located inside the guide seat 5. The moving mechanism 6 further includes a driving motor 601 fixedly installed on the outer wall of the gantry 3. The output end of the driving motor 601 is fixedly connected with a worm 602. A worm gear 603 is meshed on the outer side of the worm 602. A transmission shaft 604 is fixedly connected to the inner side of the worm gear 603.

Second bevel gears 606 with the same direction are meshed on the outer sides of the two first bevel gears 605, and the second bevel gears 606 are fixedly connected with the driving lead screws 607.

[0046] Specifically, when the fire door with window 12 of the present invention moves between the material area and the electrolytic cell, the driving motor 601 fixedly installed on the outer wall of the gantry 3 is started. The output end of the driving motor 601 will drive the worm 602 to rotate. Since a worm gear 603 is meshed on the outer side of the worm 602, the worm gear 603 and the transmission shaft 604 inside the worm gear 603 are driven to rotate. Oppositely directed first bevel gears 605 are fixedly connected to both ends of the transmission shaft 604. Second bevel gears 606 with the same direction are meshed on the outer sides of the two first bevel gears 605, thereby driving the two driving lead screws 607 to move in opposite directions. Since the thread directions of the two driving lead screws 607 are opposite, the guide seat 5 can be driven to move stably along the guide rail 4 by the two driving lead screws 607 under the action of the lead screw nut 608. Moreover, a driving hydraulic cylinder 7 is fixedly installed on the top of the guide seat 5. The output end of the driving hydraulic cylinder 7 is fixedly connected with a mounting frame 8. A hanging mechanism 9 is arranged on the mounting frame 8, so that the output end of the driving hydraulic cylinder 7 can drive the hanging mechanism 9 on the mounting frame 8 to suspend the fire door with window 12. Subsequently, under the drive of the moving mechanism 6, the guide seat 5 will drive the fire door with window 12 below to move, enabling the fire door with window 12 to move stably between the material area and the electrolytic cell, facilitating the fire door with window 12 to move above the electrolytic cell. Then, the output end of the driving hydraulic cylinder 7 will send the fire door with window 12 into the electrolytic cell for electroplating processing. In addition, the transmission mode of the worm gear 603 and the worm 602 has a self-locking function, which can limit the position of the guide seat 5 staying at the processing position, enabling the fire door with window 12 below the guide seat 5 to stay stably in the electrolytic cell for electroplating processing.

[0047] In the embodiment, refer to Figures 5-6, in order to firmly hang the fireproof door with a window 12 in the electrolytic cell for electroplating processing, the hanging mechanism 9 includes a first fixing frame 901 fixedly connected to the bottom of the mounting frame 8.

An adjusting mechanism 10 is provided inside the mounting frame 8.

[0048] Specifically, when the present invention hangs the fireproof door with a window 12, the first electric cylinder 902 fixedly installed on the outer wall of the first fixing frame 901 is started, so that the output end of the first electric cylinder 902 will drive the first clamping plate 903 to fit and press against the first outer surface 1201 of the fireproof door with a window 12. The second electric cylinder 905 fixedly installed on the outer wall of the second fixing frame 904 is started, so that the output end of the second electric cylinder 905 will drive the second clamping plate 906 to fit and press against the second outer surface 1202 of the fireproof door with a window 12, so that the fireproof door with a window 12 is fixedly hung under the combined extrusion of the first clamping plate 903 and the second clamping plate 906.

The fireproof door with a window 12 can be firmly hung in the electrolytic cell for electroplating operation, improving the electroplating effect of the fireproof door with a window 12.

[0050] In the embodiment, referring to Figures 7-8, in order to grasp the fire door with a window 12 at different positions of the window installation groove 1205, the adjusting mechanism 10 includes a fifth electric cylinder 1001 and a sixth electric cylinder 1002 fixedly installed inside the installation frame 8. The output end of the fifth electric cylinder 1001 is fixedly connected to the first moving frame 907, and the output end of the sixth electric cylinder 1002 is fixedly connected to the second moving frame 910. The adjusting mechanism 10 further includes a sliding groove 1003 opened inside the installation frame 8, and the first moving frame 907 and the second moving frame 910 are slidably connected to the sliding groove 1003.

[0051] Specifically, when the present invention grasps the fire door with a window 12 at different positions of the window installation groove 1205, first, the moving mechanism 6 drives the guiding seat 5 to move above the window installation groove 1205. Subsequently, the output end of the seventh electric cylinder 1101 drives the first moving frame 907 to slide in the sliding groove 1003 and move to the outside of the first inner surface 1203. The output end of the sixth electric cylinder 1002 drives the second moving frame 910 to slide in the sliding groove 1003 and move to the outside of the second inner surface 1204, so that the third clamping plate 909 below the first moving frame 907 and the fourth clamping plate 912 below the second moving frame 910 can be positioned on the outside of the first inner surface 1203 and the second inner surface 1204. Finally, by driving the first clamping plate 903, the second clamping plate 906, the third clamping plate 909 and the fourth clamping plate 912, the fire door with a window 12 at different positions of the window installation groove 1205 can be grasped.

[0052] In the embodiment, referring to Figure 9 , in order to improve the stability when grasping the fire door with a window 12, the stabilizing mechanism 11 includes a seventh electric cylinder 1101 fixedly installed on the outer wall of the first fixing frame 901. The output end of the seventh electric cylinder 1101 is fixedly connected to a first L-shaped bracket 1102.

[0053] Specifically, when the fire door with a window 12 is firmly fixed under the combined action of the first splint 903, the second splint 906, the third splint 909 and the fourth splint 912, the first splint 903, the second splint 906, the third splint 909 and the fourth splint 912 are distributed on the side of the fire door with a window 12 close to the window installation groove 1205. At this time, the seventh electric cylinder 1101 on the first fixing frame 901 is started, so that the first L-shaped bracket 1102 slides in the first guiding groove 1103 and drives the fifth splint 1105 to move to the symmetric side of the first splint 903. Then, the eighth electric cylinder 1104 on the first L-shaped bracket 1102 is started, so that the fifth splint 1105 fits and presses against the first outer surface 1201. Similarly, the ninth electric cylinder 1106 on the second fixing frame 904 is started, so that the second L-shaped bracket 1107 slides in the second guiding groove 1108 and drives the sixth splint 1110 to move to the symmetric side of the second splint 906.
