After the installation is completed, the sliding plate can be pushed on one side of the rack rod at the top layer to control the sliding plate to slide on the inner wall of the slide groove in the direction away from the rack rod, and the end of the sliding plate away from the rack rod is placed on the surface of the construction building. At the same time, the two screws at the top of the sliding plate will slide on the inner wall of the rectangular groove, and push the threaded ring to rotate on the outer surface of the two screws respectively, so that the threaded ring moves downward on the outer surface of the screw and the bottom end of the threaded ring is pressed against the outer surface of the rack rod to fix the position of the sliding plate. When the construction workers move to the building at the transfer plate of the top layer rack rod, they can step on the surface of the sliding plate and fill the gap between the top layer rack rod and the building through the sliding plate, so as to avoid as much as possible that the construction workers' feet are stuck between the top layer of the ladder cage and the construction building when they climb onto the construction building through the top layer, causing safety accidents.
[0007] Preferably, the outer surface of the threaded ring is rotatably connected to a circular ring, one side of the circular ring is fixedly connected to a slotted rod, the outer surface of the slotted rod is provided with a plurality of slots, and the inner walls of the slots are slidably connected to an insertion rod.
[0008] The effect achieved by the above components is: after the threaded ring is rotated to press the bottom end against the outer surface of the frame rod and fix the position of the sliding plate, the insertion rod can be inserted into a slot on the outer surface of the slot rod so that the insertion rod is stuck on one side of the frame rod, further limiting the angle between the screw rod and the sliding plate and the frame rod, and avoiding as much as possible the downward deflection of the sliding plate away from the end of the frame rod.
[0009] Preferably, the top end of the insertion rod is fixedly connected with a slot block, and the outer surface of the slot block is provided with two grooves.
[0010] The effect achieved by the above components is that by pinching the two grooves on the outer surface of the slot block, the slot block can be more conveniently controlled to insert the plug rod into the slot or pull the plug rod out from the slot.
[0011] Preferably, a plurality of protrusions are fixedly connected to the outer surface of the threaded ring, and the protrusions are distributed in a circular pattern on the outer surface of the threaded ring.
[0012] The effect achieved by the above components is that the threaded ring can be pushed more conveniently to control its rotation by holding the protrusion on the outer surface of the threaded ring.
[0013] Preferably, a stopper is fixedly connected to the top end of the screw, and the length of the stopper is greater than the diameter of the screw.
[0014] The effect achieved by the above components is: by setting a stopper, the movement range of the threaded ring on the outer surface of the screw can be limited, so as to avoid as much as possible the threaded ring moving upward on the outer surface of the screw when disassembling and assembling the ladder cage, falling off the screw surface and being lost, affecting the normal use of the auxiliary device.
[0015] Preferably, the outer surface of the transfer plate is provided with an anti-slip device, and the anti-slip device includes several rubber plates, the bottom end of the rubber plate is fixedly connected to the top end of the transfer plate, and the top end of the rubber plate is fixedly connected with several convex strips, and the convex strips are linearly distributed on the outer surface of the rubber plate.
[0016] The effect achieved by the above components is that when construction workers step onto the transfer board, stepping on the convex strips on the surface of the rubber board can increase the friction between the soles of the feet and the transfer board, making it less likely for construction workers to slip and fall when stepping on the transfer board.
[0017] Preferably, a plurality of water seepage grooves are provided on the outer surface of the transfer plate. The water seepage grooves are linearly distributed on the outer surface of the transfer plate, and the width of the water seepage grooves is about 1 to 2 cm.
[0018] The effect achieved by the above components is that on rainy days, rainwater entering the surface of the transfer plate can seep downward through the seepage groove, thereby preventing rainwater from accumulating on the surface of the transfer plate and causing the surface of the transfer plate to slip as much as possible.
[0019] Preferably, two inclined grooves are provided at the top end of the inner wall of the water seepage trough, and the two inclined grooves are respectively located on both sides of the top end of the inner wall of the water seepage trough.
[0020] The effect achieved by the above components is that by providing the inclined groove, rainwater on the surface of the transfer plate can pass through the inclined groove more easily and quickly into the interior of the rectangular groove.
[0021] Compared with the prior art, the advantages and positive effects of the present invention are:
[0022] In the utility model, an auxiliary device is provided, which pushes the sliding plate to slide in a direction away from the frame rod, and places the end of the sliding plate away from the frame rod on the surface of the construction building. When the construction workers move to the building through the transfer plate, they can step on the surface of the sliding plate, and the sliding plate fills the gap between the top frame rod and the building, thereby avoiding as much as possible the safety accidents caused by the feet of the construction workers getting stuck between the top floor of the ladder cage and the construction building when they climb onto the construction building through the top floor.

The outer surface of the screw rod 24 is threadedly connected with a threaded ring 25. The outer surface of the screw rod 24 slides on the inner wall of the rectangular groove 23. When installing the safety ladder cage, place the reinforcement rod 4 at the bottom layer on the ground, insert the four vertical rods of the frame rod 1 into the four corners of the reinforcement rod 4, and then The two screw rods 24 on the top of the sliding plate 22 will slide on the inner wall of the rectangular groove 23, respectively, and the threaded ring 25 will be pushed on the outer surface of the two screw rods 24 to rotate, so that the threaded ring 25 moves downward on the outer surface of the screw rod 24, and the bottom end of the threaded ring 25 is pressed against the outer surface of the frame rod 1, thereby fixing the position of the sliding plate 22. When the construction worker moves to the building at the transfer plate 5 of the top frame rod 1, he can step on the surface of the sliding plate 22 to fill the gap between the top frame rod 1 and the building through the sliding plate 22, thereby avoiding as much as possible that the construction worker's feet are stuck between the top floor of the ladder cage and the construction building when climbing to the construction building through the top floor.
[0031] Reference Figure 2-6 The top of the plug rod 29 is fixedly connected to a groove block 210, and the outer surface of the groove block 210 is provided with two grooves. By pinching the two grooves on the outer surface of the groove block 210, it is more convenient to control the insertion of the plug rod 29 into the slot 28 or to pull out the plug rod 29 from the slot 28.
