DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the furnace door repair landing gear involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0022] Reference Figure 1-4 The utility model provides a furnace door repair landing gear, including a stand 1, a bracket 2, a guide rail 3, a lifting assembly and a power assembly. A bottom plate 4 is installed at the bottom of the stand 1, the guide rail 3 is installed on the bottom plate 4, the bracket 2 is installed on the guide rail 3 through roller sliding, and the end of the bracket 2 close to the stand 1 can slide up along the stand 1, the lifting assembly is installed at the bottom of the bracket 2, and the bracket 2 is driven to slide up by the lifting assembly, the power assembly is connected to the lifting assembly, and the lifting assembly is driven to operate by the power assembly.

[0023] The lifting assembly includes a first screw rod 5, a first threaded seat 6 and a first connecting rod 7. The first screw rod 5 is horizontally rotatably installed on the surface of the base plate 4. The first threaded seat 6 is threadedly installed on the surface of the first screw rod 5. One end of the first connecting rod 7 is rotatably connected to the bracket 2, and the other end is rotatably connected to the first threaded seat 6. In this way, the first screw rod 5 only needs to rotate to drive the first threaded seat 6 to move, and the first threaded seat 6 will pull the bracket 2 to move through the first connecting rod 7, so that it is close to the stand 1 and the end of the bracket 2 will move up along the stand 1.

[0024] The lifting assembly also includes a second screw rod 8, a second threaded seat 9 and a second connecting rod 10. The second screw rod 8 is vertically installed on the base plate 4. The second threaded seat 9 is threadedly installed on the surface of the second screw rod 8. One end of the second connecting rod 10 is rotatably connected to the side of the bracket 2, and the other end is rotatably connected to the second threaded seat 9. In this way, as long as the second screw rod 8 rotates, it will drive the second threaded seat 9 to move, and the second threaded seat 9 will pull the end of the bracket 2 upward through the second connecting rod 10, thereby further facilitating the bracket 2 to rise along the stand 1.

[0025] The power assembly includes a motor 11, which is fixedly mounted on the base plate 4. A transmission assembly is connected between the motor 11 and the first screw rod 5 and the second screw rod 8. Thus, the first screw rod 5 and the second screw rod 8 can be driven to rotate by simply starting the motor 11.

[0026] The transmission assembly includes a gear box 12, a driving bevel gear 13 and a driven bevel gear 14. The gear box 12 is fixedly mounted on the base plate 4. The driving bevel gear 13 and the driven bevel gear 14 are both rotatably mounted in the gear box 12, and the driving bevel gear 13 is meshed with the driven bevel gear 14. At the same time, the driving bevel gear 13 is coaxially connected with the first screw rod 5 and the output shaft of the motor 11, and the driven bevel gear 14 is coaxially connected with the second screw rod 8. In this way, when the motor 11 rotates, it will drive the first screw rod 5 and the second screw rod 8 to rotate through the driving bevel gear 13 and the driven bevel gear 14.

[0027] The surfaces of the first screw rod 5 and the second screw rod 8 are both covered with a protective cover 15, and the protective cover 15 is foldable. The protective cover 15 on the first screw rod 5 is connected between the end of the first screw rod 5 and the first threaded seat 6, and the protective cover 15 on the second screw rod 8 is connected between the end of the second screw rod 8 and the second threaded seat 9. In this way, the first screw rod 5 and the second screw rod 8 can be protected.

[0028] A guide groove 16 is provided on the surface of the stand 1 , a sliding shaft 17 is slidably installed in the guide groove 16 , and the sliding shaft 17 is rotatably installed at the bottom of the bracket 2 , so that the bracket 2 can be easily raised along the stand 1 .

[0029] Therefore, the complete usage process is to first place the furnace door that needs to be repaired on the bracket 2 through a trailer, and then start the motor 11. The motor 11 will drive the first screw rod 5 and the second screw rod 8 to rotate through the active bevel gear 13 and the driven bevel gear 14. The rotation of the first screw rod 5 will drive the first threaded seat 6 to move, and the first threaded seat 6 will pull the bracket 2 to move through the first connecting rod 7 to move it close to the stand 1. At this time, under the action of the guide groove 16, the end of the bracket 2 will move up along the guide groove 16. At the same time, when the second screw rod 8 rotates, it will drive the second threaded seat 9 to move, and the second threaded seat 9 will pull the end of the bracket 2 up through the second connecting rod 10, thereby further facilitating the bracket 2 to rise along the stand 1. In this way, the entire furnace door can be lifted, which is convenient for workers to repair.

[0030] In summary, during the entire use process, the entire landing gear is driven to work by the lifting assembly and the power assembly. In contrast, the lifting assembly and the power assembly are both installed on the base plate 4. In this way, workers do not need to frequently climb up to perform maintenance work. In contrast, it greatly reduces the difficulty of maintenance and effectively improves maintenance safety.

[0031] At the same time, during use, since the lifting assembly and the power assembly are both installed on the base plate 4, this will effectively lower the center of gravity of the entire landing gear, thereby making the entire landing gear more stable, which further improves the safety during maintenance and use.
