Description

Technical Field

[0001] This utility model relates to the field of scaffolding pedal technology, specifically a scaffolding pedal device with anti-fall locking function. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It is divided into external scaffolding and internal scaffolding according to its location. With the emergence of a large number of modern large-scale building systems in my country, the use of scaffolding can make construction safer and more reliable, and the loading and unloading speed is faster. It has been widely used in many projects in China and has achieved good results.

[0003] As disclosed in the patent announcement CN215212287U, a novel scaffolding platform includes a steel frame. Multiple connecting rods are arranged on the inner wall of the steel frame, and a steel mesh is arranged on the top of the connecting rods on the inner wall of the steel frame. Fixed frames are arranged on both sides of the steel frame, and an arc-shaped locking buckle is provided on one side of each fixed frame. A locking mechanism is provided on the front of each arc-shaped locking buckle. The beneficial effects of this invention are as follows: The arc-shaped locking buckles are connected to both sides of the platform via fixed frames, and a locking mechanism is provided on the arc-shaped locking buckles. When installing the platform, the locking plate can be pushed upwards first to lock the arc-shaped locking buckle onto the crossbar of the scaffolding. Then, the locking plate is slid down, and the crossbar is locked by applying a downward force to the locking plate. No bolts are required for fixing. Furthermore, during disassembly, the locking plate can be pushed upwards to unlock it. Installation is convenient, safe, and reliable.

[0004] Although the aforementioned patent uses a downward force applied to the locking plate to lock the crossbar, the simple downward sliding locking method of the locking plate has the defect of insufficient dynamic stability. When the scaffolding is subjected to external vibration, the locking plate is prone to displacement, which may cause the lock to open unexpectedly, posing a safety hazard. Utility Model Content

One end of the screw rod 8 is rotatably connected to the central guide groove 6 through a bearing, and the other end extends to the outside of the movable plate 3 and is fixedly connected to a hexagonal bolt head 9. The central support bar 7 is threadedly connected to the screw rod 8. In this embodiment, the cooperation between the lead screw 8 transmission mechanism and the guide groove 6 sliding mechanism enables free adjustment of the scaffold width, solving the technical problem of limited adjustment range and inconvenient operation of scaffold ...

[0014] like Figure 1 and Figure 2As shown, the upper gripper 4 is symmetrically fixed at both ends of the movable plate 3 on the side away from the pedal body 1. A lower gripper 5 is movably mounted below the upper gripper 4. A locking mechanism is provided between the lower gripper 5 and the upper gripper 4. The locking mechanism includes fixing blocks 10 symmetrically fixed to the outer sides of the lower gripper 5 near the movable plate 3. The upper ends of the fixing blocks 10 are rotatably connected to the upper gripper 4 via a rotating shaft. Arc-shaped grooves 11 are provided on the opposing sides of both the upper gripper 4 and the lower gripper 5. The locking mechanism also includes a U-shaped frame 12 laterally fixed to the outer side of the upper gripper 4 away from the movable plate 3, and a... The sleeve 13 on the outside of one side of the upper jaw 4 has a movably sleeved insert rod 14 inside the sleeve 13. The ends of the two insert rods 14 away from the upper jaw 4 are integrally formed with a handle 15. The ends of the insert rods 14 away from the handle 15 are elastically connected to the U-shaped frame 12 by a spring 16. The spring 16 is sleeved on the outside of the insert rod 14, with one end fixed to the U-shaped frame 12 and the other end fixed to the flange of the insert rod 14. The locking mechanism further includes an insertion hole 17 opened on the side of the lower jaw 5 away from the fixing block 10. The insert rod 14 is inserted and fixed to the insertion hole 17. The two lower jaws 5 are each fixed with a handle 18 on the opposite side. In this embodiment, the automatic locking function of the pedal under load is ensured by the cooperation of the spring 16 pre-tightening rod 14 locking mechanism and the arc-shaped clamping groove, thus solving the safety hazard problem of the locking mechanism being easy to loosen and fall off in the prior art.

[0015] Working principle: When the pedal needs to be installed, the operator first holds the handle 15 and pulls it outward, causing the end of the insertion rod 14 to retract into the sleeve 13 and compress the spring 16. At this time, the lower clamp 5 can rotate freely. Flip the lower clamp 5 downward to open it, so that the scaffold crossbar can smoothly enter the arc groove 11 between the upper clamp 4 and the lower clamp 5. Then flip the lower clamp 5 upward to close it. After releasing the handle 15, the insertion rod 14 automatically inserts into the insertion hole 17 of the lower clamp 5 under the elastic force of the spring 16 to complete the locking and fixing. When the pedal width needs to be adjusted, the screw 8 is driven to rotate by rotating the hexagonal bolt head 9, which drives the support bar 7 to slide in the guide groove 6, so that the movable plate 3 moves relative to the pedal body 1. When disassembling, hold the handle 15 again to retract the insertion rod 14, and then flip the lower clamp 5 downward to open it for quick unlocking.
