[0023] See also Figure 1-4 The utility model provides a technical solution: a ladder fixing device, including a fixed base 1 and a ladder fixing mechanism, the fixed base 1 has two first inclined grooves 2, the ladder fixing mechanism includes a fixed pressing plate 3, a threaded rod 5, a rotating wheel 6, a rotating shaft 8, a sleeve 9, two telescopic shafts 10 and an arc-shaped support plate 11, the fixed pressing plate 3 is slidably connected to the inside of the fixed base 1, the front side of the fixed pressing plate 3 is provided with two second inclined grooves 4, the threaded rod 5 is threadedly connected to the inside of the fixed base 1, the front end of the threaded rod 5 is rotatably connected to the rear side of the fixed pressing plate 3, the rotating wheel 6 is fixedly connected to the rear end of the threaded rod 5, a receiving groove 7 is provided on the surface of the fixed base 1, the rotating shaft 8 is rotatably connected to the inside of the receiving groove 7, the sleeve 9 is fixedly sleeved on the surface of the rotating shaft 8, the two telescopic shafts 10 are both slidably sleeved inside the sleeve 9, and the arc-shaped support plate 11 is fixedly welded to the top of the two telescopic shafts 10.

[0024] When the ladder fixing device is in use, the maintenance personnel first put the lower end of the ladder into the two first inclined grooves 2, and then rotate the threaded rod 5 through the rotating wheel 6. The threaded rod 5 rotates and drives the fixed pressure plate 3 to slide forward through the threaded connection between the fixed base 1. The fixed pressure plate 3 slides forward and drives the two second inclined grooves 4 to be fixed and clamped on the lower end of the ladder, and then the lower end of the ladder can be clamped and fixed by the two second inclined grooves 4 and the two first inclined grooves 2.

[0025] A slide groove 12 is provided inside the sleeve 9, and two fixed blocks 13 are slidably connected inside the slide groove 12. Springs 14 are fixedly connected to the opposite ends of the two fixed blocks 13. Protrusions 15 are fixedly connected to the surfaces of the two fixed blocks 13. Fixed grooves 16 are provided at the lower ends of the two telescopic shafts 10, and the two fixed blocks 13 are slidably connected to the inside of the two fixed grooves 16 respectively.

[0026] The maintenance personnel rotates the shaft sleeve 9 and moves it out of the interior of the storage groove 7. The maintenance personnel slides the two telescopic shafts 10 upward and drives the arc-shaped support plate 11 to slide upward and support on the upper end of the ladder. At this time, the spring 14 releases the elastic force and pushes the two fixed blocks 13 to slide opposite to each other at the same time. The two fixed blocks 13 slide opposite to each other and slide into the interior of the two fixed slots 16 respectively, so that the two telescopic shafts 10 can be fixed and positioned by the two fixed blocks 13. At this time, the two telescopic shafts 10, the ladder and the fixed base 1 can form a tripod structure. The tripod structure has strong stability, which ensures the stability of the ladder during use and prevents the ladder from tilting and tipping over due to insufficient stability. Only one maintenance personnel is needed to climb the ladder to repair the power facilities, which not only ensures the safety of the maintenance personnel standing on the ladder surface, but also reduces the manpower consumption required for the maintenance process.

[0027] When the ladder is finished using, the maintenance personnel slides the two protrusions 15 relative to each other with their fingers. The two protrusions 15 slide relative to each other and drive the two fixed blocks 13 to slide relative to each other and squeeze the spring 14. At this time, the spring 14 gives the two fixed blocks 13 a reverse elastic force. The two fixed blocks 13 slide relative to each other and move out of the two fixed slots 16, thereby releasing the fixing effect of the two fixed blocks 13 on the two telescopic shafts 10. The maintenance personnel can slide the two telescopic shafts 10 downward and hide them inside the shaft sleeve 9. Then, the maintenance personnel rotate the shaft sleeve 9 to fold it into the storage slot 7. By setting the shaft sleeve 9 to a foldable structure, it is convenient for maintenance personnel to carry the fixing device.

[0028] The two cams 15 are slidably supported on the upper and lower ends of the ladder, and the two cams 15 are slidably supported on the lower ends of the ladder, and the two cams 15 are slidably supported on the lower ends of the ladder.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
