[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please refer to Figures 1-4 This utility model discloses an auxiliary device for preventing falls during the erection of power line towers, comprising a base plate 1, a positioning pin 11, and an installation component 2. The base plate 1 and the positioning pin 11 are the same structures as those in the background patent, which constitute the main structure of the auxiliary device for preventing falls. The installation component 2 is an installation structure used for installing other structures. An installation assembly is provided on the inner side of the installation component 2. The installation assembly includes a guide sleeve 22, through which the positioning pin 11 passes and the base plate 1, thereby inserting into the ground.

[0027] The positioning pin 11 is equipped with a locking block 13 and an insertion port 14. A guide rail 3 is provided on one side of the inside of the guide sleeve 22. The locking block 13 is slidably connected to the guide rail 3. When the locking block 13 reaches the guide sleeve 22, the guide rail 3 needs to be rotated to make the locking block 13 engage with the guide rail 3, so that the locking block 13 slides into the guide rail 3. A locking rail 31 is provided at the bottom of the guide rail 3. The locking block 13 is installed and removed in the locking rail 31. When the locking block 13 reaches the locking rail 31, it cannot move downward. At this time, by rotating the positioning pin 11, the locking block 13 is locked in the locking rail 31, and the positioning pin 11 cannot move up or down.

[0028] A hexagonal groove 32 is provided on the other side of the guide sleeve 22. A hexagonal block 33 is slidably arranged inside the hexagonal groove 32. An insert block 34 is provided on the hexagonal block 33. The insert block 34 is installed and removed in the socket 14. When the locking block 13 rotates to the outermost position of the locking rail 31, the socket 14 engages with the insert block 34. A pull rod 4 is movably arranged on the outer side of the hexagonal groove 32. The pull rod 4 can rotate and extend. One side of the pull rod 4 is locked in the hexagonal block 33 and rotates. That is, by pushing the pull rod 4, the insert block 34 is inserted into the socket 14, which can fix the positioning pin 11 and prevent the positioning pin 11 from rotating.

[0029] A sliding tube 42 is provided on the top of the outer side of the hexagonal groove 32. A fixing block 44 is slidably installed inside the sliding tube 42. Two fixing ports 41 are provided on the pull rod 4. The fixing block 44 is installed and removed in the fixing ports 41. A spring 43 is provided on the top of the inner side of the sliding tube 42. The bottom of the spring 43 is connected to the fixing block 44. When the insert 34 is inserted into the insertion port 14 or removed from the insertion port 14, the fixing block 44 is respectively connected to the two fixing ports 41. At this time, the spring 43 pushes the fixing block 44, thereby inserting the fixing block 44 into the fixing port 41, thus fixing the insert 34. When removing it, the top of the fixing block 44 also includes a pulling structure. That is, by pulling the fixing block 44 from the top, the fixing block 44 is removed from the fixing port 41. When the pull rod 4 is extended or retracted, the pull rod 4 can be rotated, so that the fixing block 44 cannot be inserted into the fixing port 41. After installation, it can be rotated to the appropriate position.

[0030] The base plate 1 has a sliding groove 12 on its inner side, and the mounting part 2 has sliding rails 21 on both sides. The sliding rails 21 are slidably connected to the sliding groove 12, that is, the sliding rails 21 are stuck in the sliding groove 12 and slide up and down. The bottom side of the sliding groove 12 has a screw hole 23, and a bolt 24 is installed inside the screw hole 23. The bolt 24 is threadedly connected to the screw hole 23. The top of the bolt 24 is stuck at the bottom of the mounting part 2 and rotates. When the positioning pin 11 is not inserted deep enough into the ground, causing the locking block 13 and the insertion port 14 to not reach the designated position, the bolt 24 is rotated at the bottom. Through the threaded transmission, the mounting part 2 is driven to rise, so that the locking block 13 and the insertion port 14 can reach the designated position.

[0031] The working principle of this utility model is as follows: The positioning pin 11 passes through the guide sleeve 22 and the base plate 1, thus inserting into the ground. When the locking block 13 reaches the guide sleeve 22, the locking block 13 engages with the guide rail 3, allowing the locking block 13 to slide into the guide rail 3. When the locking block 13 reaches the locking rail 31, by rotating the positioning pin 11, the locking block 13 is locked in the locking rail 31. When it rotates to the outermost position of the locking rail 31, the positioning pin 11 can no longer move up or down, and the insertion port 14 engages with the insertion block 34. By pushing the pull rod 4, the insertion block 34 is inserted into the insertion port 14, thus fixing the positioning pin 11 and preventing it from rotating. When the insertion block 34 is inserted into the insertion port 14... When the fixing block 44 is aligned with a fixing port 41, the fixing block 44 is pushed by the spring 43, thus inserting the fixing block 44 into the fixing port 41 and fixing the insert block 34. In other words, during installation, it is only necessary to insert the positioning pin 11, rotate it to a certain position, and then push the pull rod 4 to fix it. This makes the operation more convenient and reduces the physical exertion of the workers. When the positioning pin 11 is not inserted deep enough into the ground, causing the locking block 13 and the insertion port 14 to not reach the designated position, the bolt 24 at the bottom is rotated. Through the threaded transmission, the mounting part 2 is driven to rise, so that the locking block 13 and the insertion port 14 can reach the designated position.
