CONCRETE IMPLEMENTATION

[0020] The utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0021] EMBODIMENT:

[0022] As Figs. 1 to 4As shown, this embodiment provides a safety protection structure for a steel platform, including a guardrail 1 and a safety ladder 2. The guardrail 1 is set along the outer edge of the top of the steel platform 3. The steel platform 3 does not have guardrails 1 at the points where people go up and down. The guardrail 1 includes a horizontal bar 4, vertical bars 5, movable railings 6, and a fixed cylinder 7. The bottom of the fixed cylinder 7 is fixedly connected to the top of the steel platform 3. Three vertical bars 5 are evenly arranged at the bottom of the horizontal bar 4. The lower end of the vertical bars 5 is slidably connected to the fixed cylinder 7. Fixing parts A8 for fixing the lower end of the vertical bars 5 are provided on the fixed cylinders 7 on both sides. Sliding frames 10 are provided at the left and right ends of the movable railings 6. The sliding frames 10 are slidably connected to the corresponding vertical bars 5. Fixing parts B9 for fixing the position of the movable railings 6 are provided on the movable railings 6. Safety ladders 2 are provided at the points where people go up and down the steel platform 3.

[0023] By using the fixed cylinder 7, vertical bar 5 and fixing part A8 together, the staff can adjust the height of the guardrail 1 according to the actual situation to facilitate the blocking of people and items. By using the movable bar 6, sliding frame 10, vertical bar 5 and fixing part B9 together, the movable bar 6 can be used to block the gap between the vertical bars 5 and the staff can adjust the height of the movable bar 6 according to the actual situation to further improve the interception effect and enhance safety.

[0024] Furthermore, a rotating cylinder 11 is rotatably connected to the bottom of the vertical rod 5 in the middle, a rotating head 12 is rotatably connected to the middle of the horizontal rod 4, a handle 13 is coaxially connected to the top of the rotating head 12, a connecting rod 14 is connected between the bottom of the rotating head 12 and the top of the rotating cylinder 11, and the three are coaxial. The rotating cylinder 11 has an opening facing downwards, and a threaded post 15 is threadedly connected to the inner cavity of the rotating cylinder 11. The bottom end of the threaded post 15 is fixedly connected to the bottom of the fixed cylinder 7 via a connecting head 16.

[0025] By using the combination of the throttle 13, rotating head 12, connecting rod 14, rotating cylinder 11, threaded column 15, and connecting head 16, workers can more easily raise and lower the movable frame to adjust the height of the guardrail 1. After the fixing parts A8 on both sides are loosened and the corresponding vertical rods 5 are released, when the worker turns the throttle 13, the throttle 13 drives the connecting rod 14 to rotate via the rotating head 12. The rotating connecting rod 14 drives the connected threaded cylinder to rotate. Since the bottom of the threaded column 15 is fixedly connected to the fixed cylinder 7, the rotating threaded cylinder can move up and down along the threaded column 15, thereby changing the up and down movement of the vertical rod 5 connected to the threaded cylinder, achieving the effect of changing the height of the guardrail 1.

[0026] Furthermore, the fixing component A8 is a fixing screw A17, the fixing cylinder 7 is evenly provided with several through holes A18 along the vertical direction, and the lower end of the vertical rod 5 is provided with a threaded hole A19 corresponding to the fixing screw A17. The position of the lower end of the vertical rod 5 is fixed by passing the fixing screw A17 through the through hole A18 and screwing it into the threaded hole A19.

[0027] The A17 fixing screw is easy to operate and provides a secure fixation.

[0028] Further, the fixing member B9 is a fixing screw B20, the middle part of the movable fence 6 is provided with a threaded hole B22 corresponding to the fixing screw B20, and the vertical rod 5 in the middle is uniformly provided with a plurality of through holes B21 in the vertical direction.

[0029] The fixing screw B20 is simple to operate and stable in fixing.

[0030] Further, the steel platform 3 is provided with an anti-skid pad 23 on the inner side of the guardrail 1.

[0031] The anti-skid pad 23 is used to avoid slipping of personnel and articles near the guardrail 1, reduce the risk of slipping over the guardrail 1, and improve safety.

[0032] The working principle and use process of the utility model are as follows:

[0033] The height of the guardrail 1 and the movable fence 6 is adjusted according to the height of personnel and articles on the steel platform 3, and under normal circumstances, the horizontal rod 4 is higher than the center of gravity of the personnel and articles, and the height of the movable fence 6 is adjusted to the middle height between the horizontal rod 4 and the top of the steel platform 3, and the height of the guardrail 1 should be adjusted first and then the height of the movable fence 6. When adjusting the height of the guardrail 1, the fixing screws A17 on both sides are unscrewed first, then the handle 13 is held and rotated, the guardrail 1 is adjusted to the appropriate height, and finally the fixing screws A17 are installed back. When adjusting the height of the movable fence 6, the fixing screw B20 on the movable fence 6 is unscrewed first, then the movable fence 6 is moved to the appropriate height, and finally the fixing screw B20 is installed back and the movable fence 6 is loosened.

[0034] The above is only a specific application example of the utility model, and does not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
