During the process of the construction workers climbing on the horizontal bars of the ladder frame 1, the guardrail 2 provided on the outside of the ladder frame 1 protects the construction workers while climbing.

[0035] Please refer to Figure 4 The protective frame assembly includes a protective frame 301, a baffle 302, an extension frame 3014, a lock hole 3015, a bracket 3016, a latch 3017 and a spring 3018;

[0036] The extension frame 3014 is connected to the inside of the ladder frame 1 and extends to the outside thereof by sliding up and down. The protective frame 301 is fixedly installed on the top of the extension frame 3014. The baffle 302 is rotatably connected to the opening of the ladder frame 1. The lock hole 3015 is opened on the surface of the protective frame 301. The bracket 3016 is fixedly connected to the surface of the baffle 302.

[0045] Please refer to Figure 2 The connecting rod assembly includes a connecting frame 304, a first fixing seat 305, a first connecting rod 306, a second connecting rod 307, a through slot 3012 and a guide rod 3013;

[0046] The connecting frame 304 is fixedly connected to the bottom of the baffle 302, the first fixed seat 305 is fixedly connected to the top edge of the support plate 303, the through slot 3012 is opened on the surface of the connecting frame 304, the guide rod 3013 is slidably connected to the inside of the through slot 3012, one end of the first connecting rod 306 is rotatably connected to the guide rod 3013, and the other end of the first connecting rod 306 is rotatably connected to the first fixed seat 305, one end of the second connecting rod 307 is rotatably connected to the connecting frame 304, and the other end of the second connecting rod 307 is rotatably connected to the movable frame 3011.

When the lifting lever 302 is in the unlocked position, the guide rod 3013 is moved upwards to unlock the lifting lever 302. When the lifting lever 302 is in the unlocked position, the guide rod 3013 is moved upwards to unlock the lifting lever 302.

[0048] Please refer to Figure 4 The first link 306 and the second link 307 in the unfolded state are used to drive the protective frame 301 to move upward, and the first link 306 and the second link 307 in the folded state are used to drive the protective frame 301 to move downward.

[0050] Working principle: First, the construction workers climb up to the protective frame 301 through the horizontal bar on the ladder frame 1. In the process of climbing on the horizontal bar of the ladder frame 1, the guardrail 2 arranged on the outside of the ladder frame 1 protects the construction workers when climbing. After the construction workers enter the protective frame 301, they rotate the baffle 302 inward, and then move the latch 3017 upward, so that the latch 3017 in the upward moving state stretches the spring 3018. After the latch 3017 is aligned with the lock hole 3015, the latch 3017 is loosened, so that the spring 3018 in the reset state drives the latch 3017 to move downward, and the downward moving state The latch 3017 is inserted into the lock hole 3015. The latch 3017 and the lock hole 3015 in the engaged state lock the position of the baffle 302. The baffle 302 in the inwardly rotated state closes the opening of the protective frame 301, thereby protecting the construction workers on the protective frame 301. As described above, the latch 3017 and the lock hole 3015 in the separated state release the position limit of the baffle 302. The baffle 302 is then rotated outward to open the opening of the protective frame 301. The open protective frame 301 is convenient for construction workers to get off the protective frame 301.

[0051] When the construction workers on the protective frame 301 need to rise to a higher position, the shaft-holding motor 309 is powered on and operated, so that the output shaft of the shaft-holding motor 309 in the running state drives the screw rod 3010 to rotate forward, and the screw rod 3010 in the forward rotating state drives the movable frame 3011 to move in the direction close to the second fixed seat 308, and the movable frame 3011 in the moving state close to the second fixed seat 308 drives the first connecting rod 306 and the second connecting rod 307 to expand, and the first connecting rod 306 in the moving state drives the guide rod 3013 to move along the trajectory of the through slot 3012, and the expanded state The first link 306 and the second link 307 in the state drive the protective frame 301 to move upward, and the screw rod 3010 in the reverse rotating state as described above drives the movable frame 3011 to move in the direction away from the second fixed seat 308, and the movable frame 3011 in the moving state away from the second fixed seat 308 drives the first link 306 and the second link 307 to fold, and the first link 306 and the second link 307 in the folded state drive the protective frame 301 to move downward, and the extension frame 3014 assists the protective frame 301 to move up and down, thereby facilitating the adjustment of the fixed position of the protective frame 301.
