Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe scaffolds, in particular to a fast-insertion steel pipe scaffold. Background Art

[0002] Steel pipe scaffolding is a temporary support and work platform system widely used in the field of construction engineering. It is usually composed of steel pipes, fasteners and other accessories. It is used to support the formwork during construction, bear construction loads and provide a safe working environment for workers. It can be built into a variety of structural forms according to different design and construction requirements, such as portal type, bridge type, cantilever type, climbing type, etc. The fast-insertion steel pipe scaffolding, also known as the buckle type, wheel buckle type or straight-insertion steel pipe scaffolding, is a new type of scaffolding system that can be quickly installed and disassembled through a specially designed plug-in interface. This scaffolding is connected to each other through pre-processed perforated steel pipes and locked by a certain mechanism to ensure the stability and safety of the structure.

[0003] The existing quick-install steel pipe scaffolding is fixed by bolts after insertion. The steel pipe connection requires manual tightening of the bolts, which has high labor intensity and relatively low work efficiency. During the repeated disassembly and assembly process, the bolts are easy to loosen, and the bolts may corrode and rust. They need to be checked and tightened frequently, otherwise it may cause safety hazards. In severe weather conditions, it is difficult for operators to tighten the bolts by hand, affecting the construction progress. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides a quick-insertion steel pipe scaffolding that can be quickly installed and disassembled without the need for additional tools, thereby significantly improving work efficiency. The spring-driven locking column can automatically maintain a stable state, reducing safety hazards caused by human factors.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a fast-insertion steel pipe scaffolding, including a sleeve frame, a plug-in pipe frame is slidably arranged inside the sleeve frame, a plurality of rectangular plates arranged at equal intervals are welded and fixed inside the upper end of the plug-in pipe frame, four frame plates are arranged at the lower end of the sleeve frame, locking columns are slidably arranged inside the four frame plates, four locking holes are opened inside the plug-in pipe frame, the four locking columns are respectively plugged into the adjacent locking holes, and limit plates are arranged on the outer arc surfaces of the four locking columns, and a connecting plate is respectively arranged between the two adjacent locking columns in front and behind, and the limit plates and the frame plates are connected. Elastic driving units are respectively arranged between the plates, linkage mechanisms are arranged on the inner sides of the two connecting plates, supporting mechanisms are arranged on the left and right sides of the sleeve frame, the elastic driving unit includes a spring arranged between the limit plate and the frame plate, four springs are respectively sleeved on the outer arc surfaces of the corresponding locking columns, the linkage mechanism includes a rotating seat arranged on the inner sides of the two connecting plates, the interiors of the two rotating seats are rotatably connected with connecting rods, a rotating frame is rotatably arranged between the front ends of the two connecting rods, a connecting column is arranged at the front end of the rotating frame, a pull plate is arranged at the front end of the connecting column, and a plurality of anti-slip protrusions are respectively arranged at the upper and lower ends of the pull plate.

[0006] As a further improvement of the utility model, casters are rotatably provided at the four corners of the lower end of the sleeve frame.

[0007] As a further improvement of the utility model, the supporting mechanism includes rectangular blocks respectively arranged on the left and right sides of the sleeve frame, the interiors of the four rectangular blocks are threadedly connected with screws, the lower ends of the four screws are respectively provided with support plates, the other ends of the four screws are respectively provided with rotating plates, and the left and right sides of the rotating plate are respectively provided with multiple evenly distributed anti-slip protrusions.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] Firstly, by pulling the pull plate, the rotating frame on the connecting column moves forward, and then the connecting rod inside it rotates and contracts, driving the connecting plates on the rotating seat to approach each other, and then driving the locking columns on the connecting plates to approach each other to the appropriate position. At this time, the spring is in a compressed state, and then the plug-in tube frame is replaced with the sleeve frame and inserted into the interior, and then the pull plate is released. At this time, the spring rebounds quickly and drives the locking column to be inserted into the locking hole inside the plug-in tube frame, so as to realize the rapid plug-in of the steel pipe scaffolding. The rectangular plate can facilitate personnel to stand on the plug-in tube frame to work, and can be quickly installed and disassembled without additional tools, which significantly improves work efficiency. The spring-driven locking column can automatically maintain a stable state, reducing safety hazards caused by human factors.

[0010] Secondly, by rotating the rotating plate, the support plate at the lower end of the screw rod moves upward to contact the ground, which can increase the contact area of ​​the steel pipe scaffolding with the ground and make the operation of the steel pipe scaffolding more stable.

[0011] Thirdly, the anti-skid protrusion 1 can prevent the operator's hand from slipping when pulling the pull plate, and the anti-skid protrusion 2 can prevent the operator's hand from slipping when rotating the rotating plate, making the operation smoother.

[0012] Fourthly, the casters can facilitate personnel to quickly move the scaffolding, thereby improving the flexibility of the steel pipe scaffolding. BRIEF DESCRIPTION OF THE DRAWINGS
