The invention discloses a controllable fastening device for a large nut. The controllable fastening device for the large nut comprises a main hollow shell and a main hollow rod body. A torque spanneris adopted as the controllable fastening device, the maximum fastening strength can be effectively controlled in the fastening process, and then the phenomenon that the thread structure is damaged dueto the fact that the fastening strength is too large can be effectively prevented; the device is provided with a rotating shaft body limiting and fixing type connecting mechanism, a transverse fixingeffect on a rotating shaft connected with a downward moving mechanism can be achieved, and the normal rotating tendency of the rotating shaft can not be influenced; in addition, the device is provided with a spiral spring elastic maximum rotating strength control mechanism, the maximum driving strength of two rotating mechanisms at the joint can be effectively controlled through the elasticity ofa spiral spring, therefore, rotating transmission is interrupted in time, and the thread damage phenomenon is reduced; and furthermore, the device is provided with a bolt connection inserting type nut sleeve screwing mechanism, in-time replacement can be conveniently achieved through bolt fixing, and then the adaptability of the device is improved.
Description
technical field [0001] The invention relates to the technical field of industrial production, in particular to a controllable fastening device for large nuts. Background technique [0002] At present, in industrial production sites, there is no lack of use and installation of large-scale equipment, and when installing large-scale equipment, large-scale bolts and nuts are required to be used in combination, and when large-scale nuts are installed, fastening devices are required. The fastening device is fastened by a wrench, but the wrench cannot effectively control the strength of the fastening, which will cause irreparable damage to the thread structure in the nuts and bolts. Contents of the invention [0003] The purpose of the present invention is to provide a large nut controllable fastening device to solve the problems raised in the above background technology. [0004] In order to achieve the above object, the present invention provides the following technical soluti...
