[0002] Construction project construction protection equipment mainly includes several categories, such as edge protection, hole protection, shaft protection, safe passages and protective sheds, external scaffolding, lightning protection and external power protection, personal protection facilities, safety nets and warning signs, as well as safety ropes and safety belts. These equipment are designed to protect the life safety and physical health of personnel on the construction site.

[0003] Take shaft protection as an example. The shaft is usually an elevator shaft. Protective facilities must be set up at the elevator shaft to prevent people from falling and falling objects from injuring people. For this reason, construction workers usually install guardrails or protective nets in front of the wall at the entrance of the elevator shaft to prevent people from falling. In order to prevent the protective net from tipping over, the staff will fit the protective net on the wall at the entrance of the elevator shaft, and then use wall nails to nail the protective net to the wall at the entrance of the elevator shaft. This not only brings trouble to the installation and subsequent removal of the protective net, but also the wall nails will damage the wall. To this end, we propose a protective device for construction engineering. Utility Model Content

[0026] Working principle: first, bring the protective net body 1 close to the outer wall of the elevator shaft, so that the protective net body 1 blocks the entrance of the elevator shaft, then hold the protective net body 1 with one hand to keep the protective net body 1 motionless, and pull one of the pull blocks 5 forward with the other hand. The pull block 5 will drive the plug post 15 to slide forward between the inner wall of the square plate 2 and the cylindrical tube 4, and the plug post 15 will drive the annular plate 16 to slide forward in the cylindrical tube 4 (in this process, the spring 17 between the cylindrical tube 4 and the annular plate 16 will be squeezed on the outer wall of the plug post 15), and the plug post 15 will also slide outward in a corresponding socket 21 on the protective net body 1 and completely slide away from the socket 21, and then keep pulling the pull block 5 without letting go while moving it toward the inner side of the wall of the elevator shaft. Move the pull block 5, the pull block 5 will drive the cylindrical tube 4 and the square plate 2 on the cylindrical tube 4 to move toward the inner side of the wall of the elevator shaft, the square plate 2 will drive the slide plate 14 and the connecting plate 6 on the slide plate 14 to slide toward the inner side of the wall of the elevator shaft (in this process, the slide plate 14 will slide in the corresponding rectangular groove 3 on the protective net main body 1), the connecting plate 6 will drive the rectangular shell 7 and the clamping plate 11 on the rectangular shell 7 to move together toward the inner side of the wall of the elevator shaft, until the side wall of the rectangular shell 7 is in contact with or close to the inner wall of the wall of the elevator shaft, the pull block 5 can be released, and under the action of the spring 17, the plug column 15 will immediately reset and be inserted into another socket 21 on the corresponding protective net main body 1, and the rectangular shell 7 can be re-fixed on the protective net main body 1 after moving.

[0027] At this time, the rear end of the connecting plate 6 is in contact with the front end surface of the wall of the elevator shaft, and the clamping plate 11 is located behind the rear end surface of the wall of the elevator shaft. Then, the hand wheel 8 is rotated, and the hand wheel 8 will drive the connecting column 13 to rotate in the inner wall of the rectangular shell 7, and the connecting column 13 will drive the bevel gear 19 to rotate in the rectangular shell 7, and the bevel gear 19 will drive the bevel gear 20 to rotate, and the bevel gear 20 will drive the stud 12 to rotate in the rectangular shell 7, and the stud 12 will drive the U-shaped plate 18 to slide forward on the outer wall of the stud 12 (in this process, the U-shaped plate 18 will slide forward in the slide groove 10 on the rectangular shell 7), and the U-shaped plate 18 will drive the clamping plate 11 to move forward until the front end of the clamping plate 11 is in contact with the rear end surface of the wall of the elevator shaft, and the hand wheel 8 can be stopped, so that the connecting plate 6 and the clamping plate 11 can be tightly fitted on the front and rear ends of the wall of the elevator shaft.
