Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1 Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] An auxiliary device for positioning and installing an elevator landing sill includes an auxiliary frame 1 for landing sill installation. The bottom of the auxiliary frame 1 for landing sill installation is fixedly connected with a supporting positioning leg 2 with a brake plate moving wheel. The right side of the auxiliary frame 1 for landing sill installation is fixedly installed with an electric cylinder I 3 through a bracket. The output end of the electric cylinder I 3 is fixedly connected with a displacement plate 4. A positioning thread groove 5 is formed on the surface of the displacement plate 4. A positioning screw 6 is threadedly connected to the inner wall of the positioning thread groove 5. One end of the positioning screw 6 is fixedly connected with a positioning collar 7. The rear side of the auxiliary frame 1 for landing sill installation is fixedly installed with a driving motor 8 through a bracket. The output end of the driving motor 8 is fixedly connected with a bidirectional threaded rod 9. Threaded sleeve plates 10 adapted to each other are respectively threadedly connected to different threaded surfaces of the bidirectional threaded rod 9. A limiting component is connected to the surface of the threaded sleeve plate 10. The top of the threaded sleeve plate 10 is fixedly connected with a vertical plate 11. A locking component is connected to the side surface of the vertical plate 11. A stabilizing frame 12 is connected to the surface of the locking component. An electric cylinder II 13 is fixedly installed on the surface of the stabilizing frame 12. The output end of the electric cylinder II 13 is fixedly installed with a clamping and positioning frame 14.

[0025] Specifically, as Figures 1-4As shown in the figure, a lifting groove 15 is formed on the surface of the landing installation auxiliary frame 1 near the middle thereof, and an abrasion-resistant and anti-slip pad 16 is fixedly connected to the inner wall of the lifting groove 15. The abrasion-resistant and anti-slip pad 16 provided in the lifting groove 15 facilitates manual carrying or carrying by tool clamping.

[0026] Furthermore, a magnetic attraction ring 17 is clamped inside the positioning collar 7. The magnetic attraction ring 17 is composed of two semi-circular magnetic attraction plates 18, and the surfaces of the two semi-circular magnetic attraction plates 18 are in contact with each other. The magnetic attraction ring 17 can be magnetically attracted and abutted at the positioning position, and a heavier trolley or other tools can be connected to the magnetic attraction ring 17.

[0027] Furthermore, the bottom of the stabilizing frame 12 is an L-shaped stabilizing plate 23. A protective vertical plate 24 is fixedly connected to the top of the L-shaped stabilizing plate 23, and the second electric cylinder 13 is located between the protective vertical plate 24 and the L-shaped stabilizing plate 23, forming a stabilizing frame 12 in the shape of a protective frame.

[0028] Specifically, as Figures 1-4 shown, the limiting component includes a limiting plate 19 and a limiting groove 20. The limiting plate 19 is fixedly connected to the side surface of the threaded sleeve plate 10. The limiting groove 20 is formed on the surface of the inner wall of the landing installation auxiliary frame 1. The inner wall of the limiting groove 20 is slidably connected to the surface of the limiting plate 19. Through the arrangement of the limiting plate 19 and the limiting groove 20, the movement track of the threaded sleeve plate 10 is limited, so that the rotation of the bidirectional threaded rod 9 can drive the threaded sleeve plate 10 adapted thereto to move.

[0029] Furthermore, the locking component includes a locking card plate 21 and a locking card slot 22. The locking card plate 21 is fixedly connected to the side surface of the stabilizing frame 12. The locking card slot 22 is formed at one end of the stabilizing frame 12. The inner wall of the locking card slot 22 is clamped and adapted to the surface of the locking card plate 21. Locking screws are threadedly connected to the inside of the locking card slot 22 and the inside of the locking card plate 21 through internal thread grooves.

[0030] Embodiment 2 Please refer to Figures 1-4 , the difference between this embodiment and Embodiment 1 is that an electric cylinder three 25 is fixedly installed inside the clamping and positioning frame 14. The output end of the electric cylinder three 25 is fixedly connected to a moving anti-slip clamping plate 26. A fixed anti-slip clamping plate 27 is fixedly connected to the side surface of the inner wall of the clamping and positioning frame 14. Electromagnetic suction plates 28 are fixedly installed inside the fixed anti-slip clamping plate 27 and the moving anti-slip clamping plate 26. The operation of the electric cylinder three 25 can drive the moving anti-slip clamping plate 26 to move closer to the fixed anti-slip clamping plate 27 to clamp and restrain the old elevator landing sill, and the electromagnetic suction plates 28 reinforce and magnetically lock the elevator landing sill.

[0031] Working principle of the utility model: When in use, the staff can use a trolley or other portable tools to move the sill installation auxiliary frame 1 to the installation location of the elevator hall door sill. Rotate the positioning screw rod 6 on the positioning collar 7 of the appropriate specification into the positioning thread groove 5 by threading, so that the positioning collar 7 of the appropriate specification can be connected to the displacement plate 4. The magnetic attraction ring 17 can be magnetically attracted and abutted at the positioning position, and a heavier trolley or other tools can be connected to the magnetic attraction ring 17 to form a rear restraint and positioning effect on the sill installation auxiliary frame 1. According to the new or old position of the elevator hall door sill, the operation of the first electric cylinder 3 can drive the displacement plate 4 to move in place. After the sill installation auxiliary frame 1 is moved and fixed, the support positioning leg 2 can be braked. The operation of the drive motor 8 can drive the bidirectional threaded rod 9 to rotate. Through the setting of the limit plate 19 and the limit groove 20, the movement track of the threaded sleeve plate 10 is limited, so that the rotation of the bidirectional threaded rod 9 can drive the threaded sleeve plate 10 adapted thereto to move. And because the thread directions of the thread surfaces on both sides of the bidirectional threaded rod 9 are opposite, the two threaded sleeve plates 10 can move in opposite directions. Using the locking and clamping relationship between the locking card plate 21 and the locking card slot 22, the locking connection and stabilization frame 12 are positioned, and the rotation of the positioning screw rod 6 strengthens the locking effect. The operation of the third electric cylinder 25 can drive the clamping and positioning frame 14 to move closer to the elevator hall door sill. The operation of the third electric cylinder 25 can drive the movable anti-slip clamping plate 26 to move closer to the fixed anti-slip clamping plate 27 to clamp and restrain the old elevator hall door sill, and the electromagnetic suction plate 28 magnetically locks and strengthens the elevator hall door sill, as well as the subsequent placement and installation operation of the new elevator hall door sill, so as to achieve the effect of stable and labor-saving replacement and auxiliary installation operation of the new and old elevator hall door sills.
