Double-headed screw rods 16 are arranged on both the top and bottom sides of the two support frames 9. The double-headed screw rods 16 are only installed inside the two support frames 9 and there is no connection relationship between them. Both ends of the two double-headed screw rods 16 are threadedly connected inside the grooves 15. A bottom plate 1 is arranged at the top of the two support frames 9. The bottom plate 1 is only placed on the top of the two support frames 9, and there is no connection relationship between the bottom plate 1 and the support frames 9. Both sides at the bottom end of the bottom plate 1 are fixedly connected with side plates 14. One side of multiple adjacent side plates 14 is respectively arranged on both sides of the support frame 9. The side plates 14 are only closely attached to the support frame 9, and there is no connection relationship between them. Bolts 13 are threadedly connected to both the front and rear ends of multiple side plates 14. One side of multiple adjacent side plates 14 is respectively arranged on both sides of the support frame 9. After removing the bottom plate 1 from the support frame 9 by rotating the bolts 13, rotate the screw rod 12 to push the top plate 11 to move, and rotate the double-headed bolt 13 to move the support frame 9 to both sides. Then, according to the distance between the two support frames 9, the bottom plate 1 of the corresponding size can be fixed to the top of the support frame 9, so as to adapt to elevator shafts of different sizes.

[0034] Both ends of two support frames 9 are provided with cavities 10. Screws 12 are threadedly connected inside the two cavities 10. The other ends of the two screws 12 are rotatably connected to a top plate 11. Rotating the screws 12 pushes the top plate 11 to move. When the top plate 11 contacts the inner wall of the elevator shaft to support the support frame 9, and at the same time, the bottom plate 1 can be supported by the top plate 11.

[0035] Strengthening rods 4 are fixedly connected to the bottom ends of the two support frames 9. The cooperation of the strengthening rods 4 and the support frames 9 can form a triangle to increase the load-bearing capacity of the support frames 9.

[0036] A baffle 5 is inserted on one adjacent side of the two support frames 9. Fixing blocks 19 are fixedly connected to the top, bottom, left, and right ends on both sides of the baffle 5. The baffle 5 can be used to seal the gap between the two support frames 9 to prevent building impurities from falling into the elevator shaft through the elevator well opening.

[0037] Fixing grooves 18 are provided on the top, bottom, left, and right sides at the front end of the two support frames 9. The fixing blocks 19 are slidably connected inside the fixing grooves 18. The fixing blocks 19 are inserted into the fixing grooves 18 and can be fixed to the inside of the fixing grooves 18 by screws, so that the baffle 5 can connect the two support frames 9.

[0038] Fixing plates 8 are fixedly connected to the bottom ends on the front side of the two support frames 9. Insertion plates 6 are fixedly connected to the bottom ends of the two support frames 9. The support frames 9 are placed inside the elevator shaft, and the insertion plates 6 are made to closely adhere to one side of the elevator shaft. At the same time, the fixing plates 8 are placed on the top of the ground. Then, the top plate 11 in contact with the inner wall of the elevator shaft can be used to install and fix the fixing frame.

[0039] A plurality of evenly distributed convex blocks 2 are fixedly connected to the top end of the bottom plate 1. Hanging ears 3 are fixedly connected to the four corners at the top end of the bottom plate 1. The side of the bottom plate 1 closely adheres to the inner wall of the elevator shaft. The hanging ears 3 can be used to hoist the bottom plate 1, and the convex blocks 2 at the top end of the bottom plate 1 can increase the surface roughness of the bottom plate 1. Z

[0040] Rotating discs 17 are fixedly connected to the outer sides of the middle parts of the two double-headed lead screws 16. The rotating discs 17 can enable the staff to better hold the double-headed lead screws 16.

[0041] Working principle: Place the bottom plate 1 on the top end of the support frame 9, insert the bolt 13 into the side plate 14 and penetrate the support frame 9, and then tighten the bolt 13 to connect the bottom plate 1 with the support frame 9; Rotate the screw rod 12 to push the top plate 11 to move, and move the top plate 11 to the side of the bottom plate 1. Fix the steel cable into the hanging ear 3 and lift the bottom plate 1 to make the support frame 9 enter the elevator shaft. Make the insertion plate 6 close to one side of the elevator shaft. At the same time, place the fixing plate 8 on the top end of the ground. Then, the top plate 11 in contact with the inner wall of the elevator shaft can be used to install and fix the fixing frame. Then, fix the baffle 5 between the two support frames 9 to prevent objects from falling from the elevator wellhead; Rotate the turntable 17 by hand, drive the double-headed screw rod 16 to rotate by the turntable 17, and then make the fixing rod 7 slide on the outside of the double-headed screw rod 16, so as to change the distance between the two support frames 9. Then, place the bottom plate 1 of the corresponding size on the top end of the support frame 9 according to the size of the support frame 9, and fix the bottom plate 1 with the bolt 13. By adjusting the size of the support frame 9, it can adapt to elevator shafts of different sizes. After the adjustment of the support frame 9 is completed, the screw rod 12 can be rotated to make the top plate 11 move. When the top plate 11 moves to the side of the bottom plate 1, it can support the part exceeding the support frame 9.
