The working principle of the chemical anchor stretcher

The chemical anchor tensioner is generally composed of a hydraulic pump, a high-pressure hose, a pressure gauge and a stretching body. The hydraulic pump is the power source, the pressure gauge reflects the output pressure of the pump, and the high-pressure hose is connected to the hydraulic pump and the stretching body. The stretching body is an executive element that realizes the stretching of the chemical anchor. It is mainly composed of a piston cylinder, a piston, a supporting bridge and a tension nut. The structure is as follows (Guide: Introduction to the difference between chemical anchor bolts and chemical anchor bolts and expansion bolts)

When working, the high-pressure oil output by the power source is delivered to the piston cylinder 3 through the high-pressure hose, and the piston in the piston cylinder moves upward under pressure, driving the tension nut to move upward. The tensile nut is threadedly connected with the working chemical anchor bolt, so that the working chemical anchor bolt is elongated, so that the chemical anchor bolt is elongated to the required deformation, and the deformation is controlled within the elastic deformation range. The working chemical anchor is restored to its original shape by hydraulic or mechanical return to complete the operation.
