Description

Technical Field

[0001] This utility model relates to the field of scaffolding clamping technology, and in particular to a construction scaffolding clamping fixture. Background Technology

[0002] In the existing technology, scaffolding is a temporary structure used in construction to support workers and materials. Scaffolding is often required to assist in construction work. However, currently, scaffolding is often moved manually. This method of moving scaffolding is labor-intensive, time-consuming, and unstable, and can easily injure the movers.

[0003] In terms of related technologies, the existing methods of manually grasping scaffolding for transportation have problems such as high labor intensity, time and effort, unstable manual grasping, and easy injury to the movers. There is still a lack of better technical solutions. Utility Model Content

[0004] In view of this, it is necessary to provide a scaffolding clamping fixture to at least solve the problems of high labor intensity, time and effort, unstable manual gripping, and easy injury to the mover in the existing related technologies for manual scaffolding handling.

[0005] This application provides a scaffolding clamping fixture, comprising: a connecting bracket, a clamping device, and a limiting device. The upper end of the connecting bracket is fixedly connected to an external mobile device, and the upper end of the clamping device is fixedly connected to the lower end of the connecting bracket. The limiting device is fixed to the connecting bracket and located on both sides of the clamping device. The clamping device includes a fixed bracket, a movable handle, a drive shaft pin, and a movable jaw. The movable handle, the drive shaft pin, and the movable jaw are all movably mounted on the fixed bracket. The movable handle is connected to the movable jaw via the drive shaft pin. The limiting device includes a limiting bracket. When a user pulls the movable handle downwards, the drive shaft pin moves upwards on the fixed bracket to open the movable jaw. When the user releases the movable handle, the drive shaft pin returns to its original position downwards on the fixed bracket to retract and clamp the scaffolding. The limiting bracket is used to restrict the position of the scaffolding.

[0006] In one embodiment, the connecting bracket includes a first crossbeam, a first connecting column, a second crossbeam, a second connecting column, and a third crossbeam. The first crossbeam, the second crossbeam, and the third crossbeam are arranged sequentially from top to bottom. The first crossbeam is fixedly connected to the second crossbeam via the first connecting column, and the second crossbeam is fixedly connected to the third crossbeam via the second connecting column. A fixing ring is provided at the upper end of the first crossbeam, and the first crossbeam is fixedly connected to an external mobile device via the fixing ring. The limiting bracket is fixed on the second crossbeam, and the fixing bracket is disposed on the third crossbeam.

[0007] In one embodiment, the limiting bracket is provided with limiting seats on both sides, the bottom end of the limiting seat is provided with a limiting V-groove, the lower end of the limiting V-groove is provided with a limiting block, and the surface of the limiting block is provided with a buffer plate.

When the user pulls the pull rod downward, the movable top rod is lifted upward around the first rotating shaft, causing the lifting groove to drive the transmission shaft pin to move upward at the strip-shaped through hole, thereby opening the movable gripper. When the user releases the pull rod, the movable top rod slides downward around the first rotating shaft, and the transmission shaft pin returns to its original position at the strip-shaped through hole, causing the movable gripper to retract and clamp the construction scaffolding.

[0010] In one embodiment, the movable gripper includes a first movable gripper and a second movable gripper, which are disposed opposite to each other and are respectively connected to the drive shaft pin. The lower ends of the first movable gripper and the second movable gripper form a clamping opening, and a scaffold clamping area is formed between the first movable gripper and the second movable gripper. The user pulls the pull rod downward, causing the movable top rod and the drive shaft pin to move upward, thereby opening the clamping opening and increasing the scaffold clamping area.
