Description

Technical Field

[0001] The utility model relates to the technical field of weld reinforcement, in particular to a weld reinforcement reinforcer. Background Art

[0002] Weld reinforcement is a process or technology to enhance the strength and stability of welded joints (welds). When a welded joint becomes a weak link in the structure due to factors such as materials, design, process or service environment, weld reinforcement technology can effectively improve the bearing capacity and durability of the joint. Composite reinforcement is a common weld reinforcement method. The weld is reinforced by using composite materials (such as carbon fiber, glass fiber, etc.) to improve its strength and durability.

[0003] When reinforcing, first grind both sides of the weld, then brush the curing glue to the pipe wall, wrap it with glass fiber cloth, and then brush the curing glue. Repeat the three-cloth and four-glue process to complete the reinforcement. However, in the prior art, workers usually brush the glue manually, which easily leads to inconsistent glue thickness. Repeated brushing is required to spread the curing glue evenly, which is time-consuming and has low glue brushing efficiency. For this reason, we propose a weld reinforcement reinforcer.

[0006] Preferably, the elastic member includes a telescopic rod, a spring and a connecting member, the telescopic rod is installed in the slide grooves opened at both ends of the support member, the spring is sleeved on the outside of the telescopic rod, the bottom end of the telescopic rod is connected to the connecting member, and the connecting member is rotatably connected to the two groups of pressure rollers.

[0007] Preferably, the gluing assembly includes a piston, a sleeve, a screw, a motor and a battery. The inner cavity of the glue box is sealingly and slidingly connected to the piston. The sleeve is installed on the top of the piston. The sleeve is threadedly connected to the screw. The top of the screw passes through the support and is connected to the output end of the motor. The batteries are arranged on both sides of the motor, and the motor is electrically connected to the battery.

[0011] 1. The fastener of the utility model can be sleeved on both sides of the weld on the outside of the pipe, so that the support can rotate along the outer wall of the pipe. The curing glue inside the glue box can be squeezed out through the glue outlet through the glue application component and evenly applied to the outside of the pipe, and the pressure roller is used to apply the glue evenly. As the glass fiber cloth is wound and the glue is applied, the thickness of the outer wall of the pipe will increase. Under the elastic force of the elastic member, the pressure roller can always fit the outer wall of the pipe to keep the glue evenly applied. Compared with the existing technology, the glue application can always be kept even, and the glue application efficiency is higher.

[0012] 2. The elastic force of the spring of the utility model will push the connecting piece to drive the pressure roller to always fit the outer wall of the pipe. The telescopic rod can keep the spring from deflecting and provide stable support. As the thickness of the outer wall of the pipe increases, the pressure roller can always fit the outer wall of the pipe to keep the glue evenly applied. By starting the motor, the screw is driven to rotate, so that the sleeve threadedly connected to it can move linearly along the axis of the screw to achieve telescoping, which can push the piston to move inside the glue box to extrude the cured glue from the glue outlet. The battery can provide power for the motor.

[0013] 3. The fastening bolt of the utility model includes a screw and a nut. The two groups of blocks are sleeved on the outer wall of the pipe, and then the screw is passed through the two groups of blocks and threadedly connected to the nut to complete the installation of the block. The two cooperate to form an annular groove, and the roller can roll in the groove to drive the support to rotate along the outer wall of the pipe to achieve glue brushing and even spreading.
