Abstract: The paper considers the challenge of creating a compact device for tensioning the cable bolts. Commercially available deep-set cable bolt of the AK01, AKS type have threaded couplings that allow the base plates to be pressed to the reinforced surface or the process equipment to be suspended. Expanding the scope of the cable bolt application, in particular, to reinforce the open-pit walls and natural rock masses, determined the need to use the cable bolts of a great length and without threaded couplings. In this case, the interaction of the end of the cable bolt with the base plate is made using collet clips. The mounting kit includes a base plate, a collet housing, and a collet. Installation of a cable bolt is carried out using a device that provides the following operations: capturing and tensioning the part of the cable bolt extending from the borehole, pressing the base plate, and fixing the collet in the holder. These actions are performed using special devices are designed to include a pneumatic-hydraulic pump and a special hydraulic cylinder. However, in some cases it is necessary to have a simpler design that is small in size and does not require any external energy sources. The article presents a compact device for performing the actions necessary for installing a base plate and securing it to the cable bolt using a collet. A specific feature of the lever mechanism used in the device is the variability of the structural arrangement. The possibility of implementing the movements of two output links from one leading link and sequentially performing operations is justified: tensioning the cable bolt, pressing the body of the collet clamp to the base plate, securing the collet to the cable bolt.
Keywords: cable bolt, tension device, lever mechanism, force analysis, variable structure, collet
