The other end of the return spring 304 is spot-welded to the sliding plate 305 to increase stability.

[0017] The working principle and usage process of this utility model are as follows: First, the operator prepares an appropriate number of load-bearing beams 201 according to the distance from the tower crane to the building. Then, the operator aligns two adjacent connecting plates 1 and inserts the connecting threaded posts 207 on one side of the connecting thick steel plate 208 into the threaded holes 206 on the inner side of the two adjacent connecting plates 1, thereby connecting the two load-bearing beams 201 through the connecting thick steel plate 208. Then, the nuts are tightened on the outside of all the connecting threaded posts 207 to fix the connecting plates 1 and the connecting thick steel plate 208. Then, all the load-bearing beams 201 can be connected and fixed in the same way. After all the load-bearing beams 201 are fixed, the operator can use the lifting rings on one side of the snap-fit ​​plate 209 to lift all the load-bearing beams 201 to the corresponding installation positions. One end of the load-bearing beam 201 is then connected to the tower crane via the connecting plate 1, and the extension plate 301 is installed on the other end face of the load-bearing beam 201. Next, the operator inserts the limiting insertion plate 211 at the bottom of the fence frame 212 into the inner side of the limiting groove 210 for fixation. At this time, the stabilizing groove 214 will be inserted into the inner side of the snap-fit ​​plate 209 for fixation. Then, the fence frame 212 is connected and fixed with bolts. Then, the operator can use the positioning groove 205 on the inner side of the snap-fit ​​steel plate 204 to snap the positioning groove 205 to the top of the positioning column 203 and fix the snap-fit ​​steel plate 204. This completes the installation of the access passage for the operator to go up and down the tower crane. It can not only facilitate the quick installation and disassembly of the passage, but also quickly adjust the overall length of the passage according to the actual installation distance. This not only ensures the installation efficiency, but also ensures that each passage has the same safety protection level, thus guaranteeing the safety of the operator. Finally, on the end face of the load-bearing beam 201 near the building, the sliding plate 305 can be pulled by the pull groove 307. Then, the sliding plate 305 can be pulled inside the extended slide groove 303. At this time, the attachment plate 306 on one end face of the sliding plate 305 will be engaged inside the building, thus meeting the different lengths of the load-bearing beam 201 and the building, further improving the applicability of the passage. Furthermore, under the pull of multiple return springs 304, the attachment plate 306 can be more stably engaged on one side of the building, further improving the safety of use.
