[0046] When the tooth block 21 moves, the tooth block 21 can drive the pointer 49 to move through the round rod 48, so that the pointer 49 can move along the mark of the scale plate 47; when the grab hook 2 and the guide rail are loosened to the maximum, the tooth block 21 drives the pointer 49 to move through the round rod 48, so that the pointer 49 can contact the touch switch of the alarm sensor 51, thereby triggering the alarm sensor 51 to alarm, so that the maintenance staff can receive the alarm signal and arrive in time, and perform maintenance work according to the direction of the pointer 49, thereby improving the maintenance efficiency of the staff.

[0047] Working principle: The staff first sets the grab hook 2 on the outside of the guide rail round rod 6 of the protection platform, and then installs the long rod 3 on the specified position of the guide seat 7 by moving the support shell 1, fixes the support shell 1 and the grab hook 2 by connecting bolts, sets the mounting plate 5 on the outside of the two long rods 3 on the side of the guide seat 7 away from the support shell 1, screws on the fastening nut 4, and moves the fastening nut 4 under the thread support of the long rod 3, so that the fastening nut 4 squeezes and fixes the mounting plate 5, and the installation of the anti-tilt device is completed;

[0048] When the guide rail rod 6 on the protection platform is loosened from the grab hook 2, the first spring 14 uses its own elastic force to drive the abutment 16 to abut against the guide rail rod 6 through the fixed block 15, and the fixed block 15 drives the two tooth blocks 21 to move through the movable rod 17, so that the tooth block 21 drives the shaft sleeve 20 to rotate vertically around the shaft block 19, and the tooth block 21 drives the clamping block 25 to move, so that the clamping block 25 moves out of the inner side of the tooth gap of the tooth block 21. At this time, the first torsion spring 23 uses its own elastic force to support the clamping block 25 to reset and rotate, so that the clamping block 25 can move to the tooth block 21. The inner side of the other tooth gaps enables the tooth block 21 to mesh with the card block 25. When the bracket 16 moves, the push plate 32, the rotating block 31, the short bolt 30 and the second torsion spring 29 drive the force block 28 to move, so that the force block 28 drives the piston 271 to move inside the cavity shell 27, so that the oil in the cavity shell 27 flows from the force block 28 to the end away from the piston 271 through the one-way valve 272, so that the piston 271 is fixed, thereby supporting the bracket 16. When the tooth block 21 moves, the tooth block 21 drives the plug block 44 through the positioning frame 43 By moving the inner side of the socket of the top block 42 out, the second spring 35 can drive the warning flag 41 and the top block 42 to move upward through the round shell 36, the third torsion spring 37, the round block 38 and the inner rod 39, so that the warning flag 41 and the top block 42 can be moved out of the inner side of the cylindrical shell 33. At the same time, the inner rod 39 can drive the side block 40 to move out between the two limit bars 34. When the side block 40 moves out between the two limit bars 34, the third torsion spring 37 drives the round block 38 to rotate four times by its own elastic force, so that the wound warning flag 41 is unfolded. When the tooth block 21 is active, the tooth block 21 can The pointer 49 can be driven to move by the round rod 48, so that the pointer 49 can move along the mark of the scale plate 47. When the hook 2 and the guide rail are loosened to the maximum, the tooth block 21 drives the pointer 49 to move through the round rod 48, so that the pointer 49 can contact the touch switch of the alarm sensor 51, thereby triggering the alarm sensor 51 to alarm, so that the alarm signal received by the maintenance staff can arrive in time, perform maintenance work according to the direction of the pointer 49, and enable the staff to reset all movable parts through the pointer 49.
