Transition device for determining the bearing capacity of a tubular anchor

摘要

The utility model refers to the mining industry and can be used to control the quality of the workings of the workings by tubular friction-type anchors. The technical problem, to which the useful model is aimed, is to ensure the capture and transmission of axial force to the tubular anchor from special mechanisms adopted in the mining industry. In the slots 2, the bodies 1 with the grooves 2 are arranged for relative movement of the clamping elements 3. A loading member 6 passes through the opening 5 formed in the body 1. The loading member 6 is arranged to contact the clamping elements 3 along the flat surfaces 7. A part of the element of loading 6, located within the body 1 and from the side opposite to the flat surfaces 7, is made in the form of a cylindrical threaded surface 8 with a longitudinal axis 9. The flat surfaces 7 are inclined to the longitudinal axis 9. A nut 10 is installed on the cylindrical threaded surface 8 with the possibility of interaction with the body 1. 4 z.s. 3, FIG.
