[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Specific examples are given below.
[0024] See also Figure 1-Figure 4 The utility model provides a scaffolding steel pedal, including a fixed frame 1; a fixed assembly is connected through the interior of the fixed frame 1; the fixed assembly includes a connecting rod 2 and a hook 21; fixed grooves 10 are provided on both sides of the fixed frame 1; a bearing 13 is rotatably connected to the fixed groove 10; a transmission rod 14 is fixedly connected to the bearing 13; screw rods 5 are fixedly connected to both ends of the transmission rod 14; a gear 8 is fixedly connected to the middle of the transmission rod 14; an operating hole 9 is provided in the middle of the fixed frame 1; the gear 8 passes through the operating hole 9; a ball nut block 11 is threadedly connected to the screw rod 5; the ball nut block 11 is fixedly connected to a first fixed block 4; two first fixed blocks 4 are provided, and are symmetrically arranged on the first fixed block 4; a clamping groove 3 is provided on the first fixed block 4. The traditional scaffolding steel pedal is generally composed of a steel plate and a hook. After the steel pipe of the scaffold is assembled, the hooks fixedly connected to the two sides of the steel plate are installed on the scaffold so that the construction workers can walk. At present, in the prior art, the hooks fixed on both sides of the steel plate are directly installed on the scaffolding. The scaffolding can be placed on the scaffolding so that construction workers can walk. However, generally, the steel pedals will move left and right after being hung on the scaffolding, resulting in gaps between the pedals. Construction workers walking on the scaffolding may easily step on empty space if they are not careful, resulting in leg injuries, etc. In order to prevent such incidents from happening, during work, the fixed frame 1 is fixed to the scaffolding through the fixed component hook 21 on the fixed frame 1, and then the gear 8 fixedly connected to the middle part of the transmission rod 14 is rotated through the operation hole 9 opened on the fixed frame 1, and the gear 8 drives the transmission rod 14 to rotate, and the fixed frame 14 is fixed. Fixed grooves 10 are provided on both sides of the fixed frame 1, and bearings 13 are movably connected to the fixed grooves 10. The transmission rod 14 is fixedly connected to the bearings 13. When the transmission rod 14 rotates, the screw rods 5 fixedly connected to the ends on both sides rotate accordingly. When the screw rods 5 rotate, they will push the ball nut block 11 to move forward. Because the first fixed block 4 is fixedly connected to the ball nut block 11, it moves forward together with the ball nut block 11. When it moves to a certain position, the clamping groove 3 provided on the first fixed block 4 will be clamped with the scaffolding to prevent the fixed frame 1 from shaking left and right.
[0025] Further, such as Figure 4As shown, a sliding groove 20 is provided in the fixed groove 10; a sliding column 19 is movably connected in the sliding groove 20; the side of the sliding column 19 not connected to the sliding groove 20 is fixedly connected to the first fixed block 4. When working, the sliding groove 20 provided in the fixed groove 10, the sliding groove 20 is movably connected with the sliding column 19, and the sliding column 19 is fixedly connected to the first fixed block 4, so that the first fixed block 4 remains fixed and does not rotate up and down to ensure that the clamping groove 3 on the first fixed block 4 can be clamped with the scaffold.
[0026] Further, such as Figure 1 and Figure 2 As shown, both ends of the connecting rod 2 pass through the fixed frame 1; both ends of the connecting rod 2 are fixedly connected with hooks 21; the fixing components are symmetrically arranged in two groups on the fixed frame 1. When working, the fixed frame 1 needs to be connected to the scaffolding, and the hooks 21 fixedly connected on both sides of the connecting rod 2 are hung on the scaffolding to fix the entire fixed frame 1 on the scaffolding.
[0027] Further, such as Figure 1 As shown, a drainage hole 6 is opened on the top of the fixed frame 1; there are multiple drainage holes 6, and the drainage holes 6 are arranged in an array. During work, when it is thunderstorm weather, in order to prevent water from accumulating on the fixed frame 1 and causing construction workers to slip when walking on it, a drainage hole 6 is opened on the top of the fixed frame 1 to allow rainwater to flow out of the drainage hole 6.
[0028] Further, such as Figure 3 As shown, a connecting column 7 is fixedly connected to the connecting rod 2; a rotating groove 16 is provided on the connecting column 7; a rotating column 17 is rotatably connected in the rotating groove 16; a rotating block 15 is fixedly connected to the rotating column 17; and a second fixed block 18 is fixedly connected to the rotating block 15. During operation, when the hook 21 needs to be connected to the scaffold, the rotating column 17 in the rotating groove 16 rotates to move the rotating block 15 upward, and at the same time, the second fixed block 18 fixedly connected to the rotating block 15 also moves upward together, and the steel pipe of the scaffold is placed in the hook 21. When the scaffold steel pipe is placed in the hook 21, the rotating column 17 is rotated again to allow the rotating block 15 and the second fixed block 18 to move downward, so that the second fixed block 18 and the end of the hook 21 remain horizontal to prevent the steel pipe of the scaffold from falling off.
[0029] Further, such as Figure 1 As shown, the connecting columns 7 are provided in four groups and are distributed on the inner side of the hook 21 . When working, the connecting columns 7 are provided in four groups and are distributed on the inner side of the hook 21 to prevent the steel pipes of the scaffolding from falling off from the hook 21 .
[0030] Working principle: The hooks fixed on both sides of the steel plate are installed on the scaffolding, so that construction workers can walk. However, the steel pedals will move left and right after being hung on the scaffolding, resulting in gaps between the pedals. Construction workers may easily step on empty space when walking on them without paying attention, resulting in leg injuries, etc. In order to prevent such incidents from happening, during work, the fixed frame 1 is fixed to the scaffolding through the fixed component hook 21 on the fixed frame 1, and then the gear 8 fixedly connected in the middle of the transmission rod 14 is rotated through the operating hole 9 opened on the fixed frame 1, and the gear 8 drives the transmission The movable rod 14 rotates, and fixed grooves 10 are opened on both sides of the fixed frame 1. Bearings 13 are movably connected to the fixed grooves 10. The transmission rod 14 is fixedly connected to the bearings 13. When the transmission rod 14 rotates, the screw rods 5 fixedly connected to the ends on both sides rotate accordingly. When the screw rods 5 rotate, they will push the ball nut block 11 to move forward. Because the first fixed block 4 is fixedly connected to the ball nut block 11, it moves forward with the ball nut block 11. When it moves to a certain position, the clamping groove 3 opened on the first fixed block 4 will be clamped with the scaffolding to prevent the fixed frame 1 from shaking left and right.
[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
