After each component is mounted on each feeding device, each device is fixed at an initial position by a locking mechanism, at this time, the displacement driving spring 3003 is in an energy storage state, after the carrier cable 2000 is clamped and the mounting position is determined by the carrier cable positioning device 5, the locking mechanism is unlocked, then the displacement driving spring 3003 is restored and the fixed clamping arm 301, the bolt positioning assembly 405 or the wire clamp positioning block 601 is pulled to a final position, and the effect of pulling the suspension assembly, the suspension assembly or the carrier cable clamp 1007 to the mounting position is achieved.

The specific structure of the locking mechanism is as follows: the sliding mounting block 3007 is fixedly connected with an extension plate 3008, the extension plate 3008 extends to the side of the sliding mounting block 3007 and is fixedly connected with a locking matching block 3009, the locking mechanism comprises a locking rotating plate 3011 which is rotatably arranged, the locking rotating plate 3011 is connected with a locking hook 3010 and a locking spring 3014 which is used for keeping the state of the locking rotating plate 3011, and the position of the sliding mounting block 3007 is locked when the locking hook 3010 is hung on the locking matching block 3009. When the lock spring 3014 is in the original length state, the lock hook 3010 is located in the sliding direction of the sliding mounting block 3007, and when the position of the sliding mounting block 3007 needs to be locked by the lock mechanism, the sliding mounting block 3007 is moved until the lock hook 3010 contacts with the lock hook 3009, because the lock rotating plate 3011 is rotatably provided, the lock hook 3010 can be gradually staggered from the lock hook 3009 by the lock rotating plate 3019, and the state of the lock spring 3014 is changed, and can be compressed or stretched in the process, so that the lock spring 3014 is in the energy storage state, and the lock hook 3010 is completely staggered from the lock hook 3009 as the sliding mounting block 3007 is continuously moved, so that the lock spring 3014 can be reset and the lock hook 3010 is pulled to be hung on the lock hook 3009, thereby fixing the positions of the lock hook 3009, the extension plate 3008 and the sliding mounting block 3007. Because the sliding mounting block 3007 is connected with the displacement driving spring 3003, the displacement driving spring 3003 also stretches or compresses to enter an energy storage state in the sliding process of the sliding mounting block 3007, after the sliding mounting block 3007 is locked by the locking hook 3010, the displacement driving spring 3003 is kept in the energy storage state until the locking matching block 3009 is separated from the locking hook 3010, the sliding mounting block 3007 is pulled to move, and then the sliding mounting block 3007 drives the fixed clamping arm 301, the bolt positioning assembly 405 or the wire clamp positioning block 601 to move to the mounting position. In the actual installation process, after the suspension assembly, the suspension assembly or the carrier cable clamp 1007 is installed on each feeding device, the positions of the suspension assembly, the suspension assembly or the carrier cable clamp 1007 can be locked by utilizing the locking mechanism, so that the whole tool can not interfere with the carrier cable 2000 in the process of moving towards the carrier cable 2000, the carrier cable 2000 can be ensured to be smoothly grabbed by the carrier cable positioning device 5, and after the installation position is determined, the locking mechanism of each tool is respectively opened, and the feeding of the suspension assembly, the suspension assembly or the carrier cable clamp 1007 is realized.

In order to facilitate the locking matching block 3009 to force the locking rotating plate 3011 to rotate after contacting the locking hook 3010, so as to ensure that the position of the sliding mounting block 3007 can be locked by using the locking hook 3010, an active contact curved surface 3016 is arranged on the locking matching block 3009, a passive contact curved surface 3015 is arranged on the locking hook 3010, the active contact curved surface 3016 contacts with the passive contact curved surface 3015 in the moving process of the locking matching block 3009, the locking matching block 3009 can push the locking hook 3010 to rotate laterally by using the radian of the two curved surfaces, and the locking hook 3010 drives the locking rotating plate 3011 to rotate, so that the locking hook 3010 is gradually staggered with the locking matching block 3009.
When the position of the sliding mounting block 3007 needs to be unlocked to move the suspension assembly, the suspension assembly or the messenger wire clamp 1007 to the mounting position, the locking hook 3010 needs to be separated from the locking matching block 3009, the locking rotating plate 3011 needs to be rotated to achieve the operation, in order to facilitate the rotation of the locking rotating plate 3011, a locking state control handle 3013 is fixedly connected to the locking rotating plate 3011, and a distance is reserved between the locking state control handle 3013 and a rotating shaft of the locking rotating plate 3011, so that the locking rotating plate 3011 can be driven to rotate around the rotating shaft by pulling the locking state control handle 3013, and the operation is simple and the response speed is high.
Although the structure of locking the sliding mounting block 3007 by using the locking spring 3014 is simpler and no additional power component is needed, the locking spring 3014 cannot effectively control itself, in order to avoid that the locking hook 3010 cannot be smoothly separated from the locking matching block 3009 due to excessive deformation of the locking spring 3014, the locking rotating plate 3011 is fixedly connected with the locking limiting block 3012, and when the locking spring 3014 is in an original length state, the locking limiting block 3012 can be attached to the substrate 3001, so that the locking spring 3014 is limited to ensure that the locking matching block 3009 can be smoothly separated from the locking hook 3010.

Because the connecting bolt 1005 needs to pass through the carrier ring 1001, a follow-up limiting rod 3005 and a displacement sensor 3006 are arranged, so that the displacement of the carrier ring 1001 is precisely controlled to ensure that the connecting bolt 1005 can be matched with the connecting bolt 1005 smoothly.
Because the connecting bolt 1005 of the suspension assembly needs to pass through the carrier cable hanging ring 1001 and the carrier cable clamp 1007, the feeding direction of the suspension assembly is perpendicular to the feeding directions of the suspension assembly and the carrier cable clamp 1007, and in order to facilitate the arrangement of the pushing device of the suspension assembly feeding device 4, the sliding rail 3002 in the pushing device of the suspension assembly feeding device 4 is vertically fixed on the sliding mounting block 3007 of the pushing mechanism of the suspension assembly feeding device 3, so that the suspension assembly feeding device 3 can drive the suspension assembly feeding device 4 to synchronously move when moving the suspension assembly, and the suspension assembly is kept above the suspension assembly all the time, thereby ensuring that the connecting bolt 1005 can pass through the carrier cable hanging ring 1001 smoothly.
