Fastening device and fastening method for anti-falling and anti-following bolts

Abstract

The invention discloses an anti-falling followed-turning-prevention bolt fastening device and a method for fastening a bolt through the device. The device and the method mainly solve the problems that bolts are fixed difficultly and are turned or fall easily during fastening and the inconvenience is caused by two-man operation during dual-nut fastening. The anti-falling followed-turning-prevention bolt fastening device comprises a socket spanner, a fixed connecting rod which is connected with the socket spanner, a fixed plate which is installed at the bottom of the fixed connecting rod and a clamping slot spanner which is connected with the fixed plate. The socket spanner comprises a handle, a socket and a connecting rod which is connected with the handle and the socket, a round hole is arranged at the upper end of the fixed connecting rod, the fixed connecting rod is sleeved on the connecting rod through the round hole, a connecting supporting ring is sleeved on the connecting rod, arranged under the fixed connecting rod and connected with the connecting rod through a fastener, the fixed plate is connected with the clamping slot spanner in a sliding mode, and the head portion of the clamping slot spanner is connected with a rotatable turning piece.

Description

technical field [0001] The invention belongs to the technical field of fastener unloading tools, and in particular relates to a fastening device and a fastening method capable of preventing bolts from falling and rotating. Background technique [0002] Many large and medium-sized mechanical equipment need to fasten a large number of bolts in the process of installation and daily maintenance. Some bolts are located in special positions and are inconvenient to operate, which consumes a lot of labor in the process of installation and maintenance. For example, during the installation process of the mine car unloading station, there are a large number of multi-standard anchor bolts to be tightened; the installation positions of the anchor bolts of curved rails and other components are narrow and cannot be operated by ordinary wrenches, which brings a lot of trouble to the installers. When the bolts of the important parts of the unloading station such as joists and curved rails ar...
