DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Example 1

[0019] Reference Figure 1-3 A climbing ladder for lathe maintenance includes a base plate 15, four connecting tubes 1 are arranged on the base plate 15, columns 2 are inserted in the four connecting tubes 1, and platforms 3 are fixedly connected to the four columns 2. When the platform 3 is repaired, the standing area is increased, which is beneficial to the safety during maintenance. Two side panels 4 are hinged on the platform 3, and a plurality of connecting columns 5 are fixedly connected at equal distances between the two side panels 4. An adjusting mechanism is arranged on one of the connecting columns 5. The four columns 2 are adjusted by the lifting mechanism. The position of the column 2 in the connecting tube 1 is adjusted by the lifting mechanism, so that the height of the platform 3 can be adjusted, so that maintenance at different heights can be carried out when the machine tool is repaired, thereby ensuring the applicability of the device.

[0020] The lifting mechanism includes an external thread, and the four columns 2 are all provided with external threads. The four connecting tubes 1 are all fixedly connected with gears 11. The four connecting tubes 1 are rotatably connected to the base plate 15 through bearings. The four gears 11 are driven by a driving mechanism. The driving mechanism includes a rotating shaft 13. The rotating shaft 13 is rotatably connected to the base plate 15 through bearings. A connecting frame 9 is fixedly connected to the rotating shaft 13. Four incomplete gear rings 10 are fixedly connected to the connecting frame 9. The four incomplete gear rings 10 are respectively meshed with the four gears 11 and rotated through the rotating shaft 13, thereby driving the connecting frame 9 to rotate, so that the incomplete gear ring 10 rotates, driving the gear 11 to rotate, thereby driving the connecting tube 1 to rotate, and adjusting the position of the column 2 in the connecting tube 1.

[0021] Example 2

[0022] Reference Figure 1-3 As another preferred embodiment of the utility model, on the basis of embodiment 1, the adjustment mechanism includes a hinged plate 6, which is rotatably connected to the connecting column 5 through a bearing, and a connecting sleeve 14 is hinged on the hinged plate 6, and the connecting sleeve 14 is fixed by a fixing mechanism.

[0023] The fixing mechanism includes a connecting rod 8, which is fixedly connected to the base plate 15. A connecting sleeve 14 is sleeved on the connecting rod 8. A fixing bolt 7 is threadedly penetrated through the connecting sleeve 14 and connected to the connecting rod 8. The fixing bolt 7 abuts against the connecting rod 8. After the height is adjusted, the inclination angle of the ladder can be adjusted so that a person can stand on the platform 3 through the ladder part. The position of the connecting sleeve 14 on the connecting rod 8 is moved, and then the fixing bolt 7 is tightened to fix the hinged plate 6, so that the hinged plate 6 supports the ladder part, which is beneficial to the stability of the ladder part.
