Description

Technical Field

[0001] This utility model belongs to the field of steel bar connection technology in building engineering, specifically relating to an intelligent anchor plate installation device, which is suitable for nuclear power, large-scale buildings and other scenarios. Background Technology

[0002] In nuclear power plants and large-scale construction projects, anchor plates are core components of rebar connections, and their installation quality directly affects the safety and stability of the structure. Currently, nuclear power plant rebar anchor plates are mostly installed manually using rebar wrenches. The entire installation process requires one person to use rebar pliers to fix the rebar, another to use a rebar wrench to tighten the anchor plate, and a separate person to perform torque checks and mark the plates after passing the checks. Therefore, the manual installation of anchor plates involves many steps and a large amount of manual labor. Furthermore, workers must work in a semi-squatting position, which is time-consuming and labor-intensive, resulting in low installation efficiency and impacting project schedules. The required torque values ​​are also high, leading to worker fatigue and potential accidents such as slippage and injury. Additionally, rebar wrenches can easily damage the surface of the anchor plate, affecting its appearance. On-site operations are often dispersed, making it difficult for quality inspectors to comprehensively supervise and inspect the anchor plate installation process, thus making quality control of anchor plate installation quite challenging.

[0003] Therefore, there is an urgent need for an intelligent anchor plate installation device to solve the above problems. Utility Model Content

[0018] The floating support mechanism automatically adjusts the support height through a lifting hydraulic cylinder, and in conjunction with the bolt adjustment of the front support mechanism, it can cover commonly used nuclear power plant steel bars without disassembling or replacing support components.

After the clamping mechanism provides a feedback signal indicating that it has reached the correct position, the tightening mechanism automatically retracts to allow for pre-fitting space. The socket used for anchor plate installation is an internal hexagonal socket, which can perfectly match the external hexagonal socket of the anchor plate. During tightening, all six sides make contact, preventing damage to the anchor plate surface.

[0021] After the tightening is qualified, the spraying mechanism automatically starts marking; after the spraying is completed, each mechanism operates in the sequence of tightening and resetting, clamping and loosening, and support lowering, without the need for manual switching instructions, reducing manual intervention and improving installation efficiency.

[0022] The foot switch can trigger clamping and tightening actions with just a light step, eliminating the need for manual valve operation; the touch screen records the specifications of the steel bars, clamping force, tightening torque, spraying time and qualification status for each installation in real time. Operators can learn to use the equipment without professional skills training. The equipment is easy to operate, which can greatly reduce the labor intensity of workers and improve the comfort and safety of operation. Attached Figure Description
