The C-shaped slider 1 includes a slider end plate 11, a slider side plate 12, and a slider base plate 13. The slider base plate 13 has slider side plates 12 vertically arranged at both ends. One end of the slider end plate 11 is integrally fixed and vertically connected to the slider side plate 12, and the other end of the slider end plate 11 is set as a cantilever end. The slider base plate 13 and the slider end plate... The slider end plate 11 is arranged parallel to both sides of the guide rail wing plate 21. The slider end plate 11 is symmetrically arranged on both sides of the guide rail web plate 22. The slider end plate 11, slider side plate 12 and slider base plate 13 form a C-shaped integrated structure. The upper and lower ends of the inner side surfaces of the slider base plate 13 and slider end plate 11 are provided with guide rollers I4. The surface of guide rollers I4 is in the same plane as the inner side surfaces of the slider base plate 13 and slider end plate 11. The upper and lower ends of the inner side surfaces of the slider side plate 12 are provided with guide rollers II5. The surface of guide rollers II5 is in the same plane as the inner side surfaces of the slider side plate 12. When the C-shaped slider 1 is engaged on the T-shaped guide rail 2, it plays a guiding role. The C-shaped slider 1 is engaged on the T-shaped guide rail 2 with a gap.

[0021] The reverse locking structure includes two pairs of symmetrically arranged reverse locking devices 3. The two reverse locking devices 3 of each pair are symmetrically arranged on both sides of the guide rail wing plate 21. One is arranged on the slider end plate 11, and the other is symmetrically arranged on the slider base plate 13. When the C-shaped slider 1 slides down in an abnormal situation, the symmetrically arranged reverse locking devices 3 play a locking role on the guide rail wing plate 21, which improves the safety performance.

[0022] The static locking structure includes a pair of symmetrically arranged static lockers 6. The static lockers 6 are symmetrically arranged on both sides of the guide rail web 22. When the C-shaped slider 1 is locked on the T-shaped guide rail 2, the static lockers 6 arranged on both sides of the guide rail web 22 work together to clamp the guide rail web 22, so that the C-shaped slider 1 is in a stationary state, that is, to statically lock the guide rail web 22, prevent the C-shaped slider 1 from sliding and causing a safety accident, and further improve the safety performance.

[0023] The reverse lock 3 is provided with two pairs, two of which are arranged in the locking holes 36 in the middle of the slider end plate 11, and the other two are arranged in the locking holes 36 on the slider base plate 13 in a symmetrical manner with the guide rail wing plate 21.

The static lock 6 comprises a locking wheel 62, a locking ratchet wheel 61, a locking slider 68, a locking guide groove 63 and a locking spring 64. The locking wheel 62 is arranged in the locking wheel groove 69 at the middle of the cantilever end of the slider end plate 11. The locking guide groove 63 is arranged at both sides of the locking wheel groove 69. The locking ratchet wheel 61 is integrally connected at both sides of the locking wheel 62. The locking wheel 62 and the locking ratchet wheel 61 can be translated and slid together along the locking wheel groove 69. The locking wheel 62 is connected with the locking sliding shaft 60 in a rotating connection structure through the locking rotating shaft 67. The locking wheel 62, the locking ratchet wheel 61 and the locking rotating shaft 67 form an integrated structure. The locking sliding shaft 60 is fixedly connected with the locking slider 68 at both ends. The locking slider 68 is arranged in the locking guide groove 63 in a sliding connection structure and is connected with the front end of the locking spring 64 arranged in the locking guide groove 63. The rear end of the locking spring 64 is fixed to the bottom of the locking guide groove 63. The compression and elongation of the locking spring 64 can drive the locking slider 68 to translate and slide forward and backward along the locking guide groove 63. The locking slider 68 drives the locking wheel 62 and the locking ratchet wheel 61 to translate and slide forward and backward together through the locking sliding shaft 60, so as to achieve the purpose of static clamping and unlocking of the guide web 22.

[0026] One end of the locking slider 68 is connected with the check pawl 65 in a rotating connection structure through a fixed shaft. The front end of the check pawl 65 is abutted on the ratchet tooth of the locking ratchet wheel 61 through a spring, so that the locking ratchet wheel 61 can only rotate in one direction. At the same time, under the action of the locking spring 64, the static clamping and locking of the guide web 22 are achieved.

[0027] The upper surface of the slider end plate 11 is provided with an unlocking pull ring 66. The unlocking pull ring 66 is fixedly connected with the locking slider 68 through a diverting pulley arranged at the bottom of the locking guide groove 63 by using a pull rope. When unlocking is needed, the unlocking pull ring 66 is pulled tight. At this time, the locking spring 64 is compressed, and the locking wheel 62 is separated from the surface of the guide web 22 and enters the locking wheel groove 69, so as to achieve the purpose of unlocking the guide web 22, and the C-shaped slider 1 can be removed from the T-shaped guide rail 2. When long-time unlocking is needed, the unlocking pull ring 66 can be hung on the hanging column on one side.

[0028] When the tower needs to be maintained, the maintenance personnel can clamp the C-shaped slider 1 of the anti-falling automatic locking device on the T-shaped guide rail 2 under the guidance of the guide rollers I 4 and the guide rollers II 5. At this time:

[0029] The locking ratchet 61 provided by the static locking structure can only rotate when the C-shaped sliding block 1 slides upward under the action of the check pawl 62. Meanwhile, the surfaces of the pair of locking wheels 62 are in contact with the surface of the rail web plate 22 under the action of the locking spring 64, thereby completing the clamping and locking of the rail web plate 22 in the static state, effectively avoiding the self-sliding of the anti-falling automatic locking device downward, and effectively solving the mental and physical trauma caused by the self-sliding of the anti-falling automatic locking device to the maintenance personnel.

[0030] The reverse locking structure is provided with two pairs of reverse lockers. When the maintenance personnel slides down due to abnormal conditions, the safety rope of the maintenance personnel will simultaneously pull down the locking pull rods 35 of the two pairs of symmetrically arranged reverse lockers, the locking pull rods 35 drive the locking contact blocks 31 to be in contact with the surface of the rail wing plate 21, and the two pairs of reverse lockers simultaneously complete the clamping and locking of the rail wing plate 21, effectively solving the sliding of the maintenance personnel under abnormal conditions and ensuring the personal safety.
