[0003] The current anti-fall guardrail for bridge construction, as described in the Chinese patent with announcement number CN219710091U, includes a fixed seat, a column, and a crossbeam. The fixed seat is composed of an upper fixed seat and a lower fixed seat. The column is fixedly arranged on the upper fixed seat. A support column is arranged between the upper fixed seat and the lower fixed seat. The two ends of the support column are respectively connected to the upper fixed seat and the lower fixed seat through a rotating shaft. A screw rod is arranged between the upper fixed seat and the lower fixed seat. A rotating seat is fixedly arranged on the upper surface of the lower fixed seat. The rotating seat and one end of the screw rod are rotatably connected. A sliding sleeve is arranged between the upper fixed seat and the screw rod, and the other end of the screw rod is provided with a handle for driving the screw rod to rotate.

[0004] Regarding the anti-fall guardrail for the above-mentioned bridge construction, the utility model inventor believes that it should be clamped at the edge of the bridge during installation, and the handle should be turned for installation. However, the handle is set on the side away from the edge of the bridge, so that during the installation process, the installer often needs to stand on the edge of the bridge to turn the handle. The installer is at risk of falling from the edge of the bridge, resulting in poor safety of the entire guardrail installation process. Utility Model Content

[0023] The core of the utility model is to provide an anti-falling guardrail for bridge construction to solve the problems raised in the background technology.

[0024] See also Figure 1-6 , Figure 1 It is a structural schematic diagram of a fall prevention guardrail for bridge construction; Figure 2 for Figure 1 A schematic diagram of the structure of part A; Figure 3 for Figure 1 Schematic diagram of the structure of part B; Figure 4 for Figure 1 Another perspective structural diagram of; Figure 5 for Figure 4 Schematic diagram of the C part structure; Figure 6 for Figure 1 Partial structural cross-sectional view of the middle fixing plate.

[0025] A fall prevention guardrail for bridge construction includes a fixed plate 1, a railing 2 is fixedly connected to the top of the fixed plate 1, and the railing 2 can be used to fence the edge of the bridge, thereby reducing the probability of construction workers falling from the edge of the bridge during bridge construction, thereby improving the safety of bridge construction. Rotating tubes 8 are fixedly connected to both sides of the fixed plate 1, and a bearing seat 9 is rotatably connected to the outer side of the rotating tube 8. A U-shaped seat 3 is fixedly connected to the bottom of the bearing seat 9. When the rotating tube 8 rotates, it can drive the fixed plate 1 to rotate.

[0026] The outer side of the rotating tube 8 is connected to the adjusting mechanism 10, and the adjusting mechanism 10 includes a worm wheel 101 fixedly connected to the outer side of the rotating tube 8, and the bottom of the worm wheel 101 is meshingly connected with a worm 102, and the worm 102 is rotatably connected to the fixed block 11. When the worm 102 rotates, it can drive the worm wheel 101, the rotating tube 8 and the supporting seat 9 to rotate accordingly, thereby realizing the adjustment of the angle of the fixed plate 1, so that when the fixed plate 1 is rotated to be level with the U-shaped seat 3, the occupied space of the entire guardrail can be reduced, thereby facilitating the subsequent storage and transportation of the guardrail.

[0027] A slide groove 14 is symmetrically provided on one side of the fixed plate 1. A clamp block 15 is provided inside the slide groove 14 and is slidably connected to the fixed plate 1. When the clamp block 15 moves upward, it can be clamped on the bridge in cooperation with the U-shaped seat 3, thereby realizing the installation of the entire guardrail. A guide rod 16 is symmetrically provided inside the slide groove 14 and is fixedly connected to the fixed plate 1. The guide rod 16 passes through the clamp block 15 and is slidably connected to the clamp block 15. The setting of the guide rod 16 can guide the up and down movement of the clamp block 15. A traction steel cable 13 is fixedly connected to the top of the clamp block 15. A groove 5 is symmetrically provided on one side of the fixed plate 1. A pulley 4 is provided inside the groove 5 and is rotatably connected to the fixed plate 1. The traction steel cable 13 passes over the outer side of the pulley 4. The pulley 4 can guide the traction steel cable 13 when the traction steel cable 13 moves.

[0028] The traction cable 13 passes through the fixed plate 1 and the rotating tube 8. The end of the traction cable 13 away from the clamping block 15 is rotatably connected to the adjusting screw 12. The outer side of the adjusting screw 12 is threadedly connected to the fixing block 11. The fixing block 11 is fixedly connected to the U-shaped seat 3. The adjusting screw 12 can pull the traction cable 13 when rotating, so that the clamping block 15 moves upward under the traction of the traction cable 13. An internal threaded tube 6 is provided on one side of the fixed plate 1. The threads on both sides of the internal threaded tube 6 are in opposite directions. The outer side of the internal threaded tube 6 is symmetrically threadedly connected to the screw 7. When the internal threaded tube 6 rotates, it can drive the two groups of screws 7 to move relative or opposite to each other, so as to adjust the position of the U-shaped seat 3.

[0029] The ends of the two sets of screw rods 7 away from the internal threaded tube 6 are fixedly connected with rectangular plug blocks 17. A rectangular plug hole 18 matching the rectangular plug block 17 is provided inside the U-shaped seat 3. The rectangular plug block 17 passes through the rectangular plug hole 18. The rectangular plug hole 18 is used for the rectangular plug block 17 to pass through, thereby limiting the rotation of the screw rod 7. A limit pin 19 is inserted inside the rectangular plug block 17. After passing through the rectangular plug block 17, the limit pin 19 can limit the rectangular plug block 17, thereby reducing the probability of the rectangular plug block 17 being separated from the rectangular plug hole 18.

[0030] When in use, the U-shaped seat 3 is placed on the bridge, and then the internal threaded tube 6 is rotated so that the internal threaded tube 6 drives the screws 7 on both sides to move oppositely when rotating, thereby driving the U-shaped seat 3 to move toward the edge of the bridge until the U-shaped seat 3 moves to the edge of the bridge, and then the worm 102 on both sides is synchronously rotated so that the worm 102 can drive the worm wheel 101 and the fixed plate 1 to rotate when rotating, until the fixed plate 1 is adjusted to a vertical state, and then the adjusting screw 12 can be rotated so that the adjusting screw 12 can pull the traction cable 13 when rotating, so that the traction cable 13 pulls the clamping block 15 to slide upward until the clamping block 15 moves downward to be tightly against the bottom of the bridge, thereby realizing the installation and fixation of the entire anti-fall guardrail, so that the subsequent staff can effectively reduce the probability of construction personnel and tools falling from the bridge when performing construction work on the bridge, thereby effectively improving the construction safety.

[0031] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
