CONNECTING DEVICE AND SYSTEM FOR SUSPENSION OF MONORAIL BEAM ON ANCHOR SUPPORT ROD Russian patent published in 2023 - IPC E21D21/00 E01B23/04 E21F13/02 E01B25/24 

FIELD: suspension systems.

SUBSTANCE: group of inventions is claimed: a connecting device and a system for hanging a monorail beam on an anchor bolt. The technical result is an improvement in the suspension system, which makes it possible to simplify the installation of monorail beams while ensuring reliable suspension and proper alignment of the beams. The connecting device for suspension of the monorail beam in the roof of the excavation contains the upper anchor, combined with the anchor bolt or made with the possibility of attaching to the anchor bolt. Also contains a clamping device for attaching to the monorail beam. The clamping device comprises a body that can be attached to a monorail beam and has a central recess with a hole. The hole is made to allow movement of the top anchor into and out of the central recess along the first axis through said hole. The clamping device contains at least one locking element. The locking element is made with the possibility of radial movement into and out of the central recess relative to the first axis between the internal locking position, in which the locking element prevents the upper anchor from leaving the central recess, and the outer open position, in which the upper anchor is able to freely move past the locking element. Each corresponding locking element is located in the corresponding radial guide recess of the housing.

EFFECT: improvement in the suspension system.
