Abstract

The invention discloses a synchronous bolt fastening device for a large sealing cover. The synchronous bolt fastening device comprises a main supporting base plate. According to the device, by means of a gear and an annular array technology, under the action of synchronous rotation, a plurality of bolts are rotated to bolt holes where the bolts are required to be installed at the same time, so that the phenomenon that the service life is relatively short due to the fact that the fastening angle of a connecting part is offset and a thread is damaged due to the stress on a single bolt can be effectively avoided; moreover, the device is provided with a reverse thread height and belt tightness state adjusting mechanism, the distance between two belt wheels can be adjusted according to the technical principle of reverse threads, so that the tension of a belt is adjusted, and the strength loss is reduced; and in addition, the device is provided with a middle maximum rotating force anti-thread-damage control mechanism, the maximum rotating force between two rotating shafts can be controlled by utilizing the elasticity of a spiral spring, so that the phenomenon that the rotating force of amotor is so large that the threads in the bolts are damaged is avoided.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a synchronous bolt fastener for a large sealing cover. Background technique [0002] At present, in industrial places, the installation between the sealing cover and the cylinder body of large-scale equipment is fastened by bolts, and the common fastening method is to install bolts one by one, which will lead to the stress caused by a single bolt. As a result, the fastening angle of the connecting parts is offset, and the occurrence of the phenomenon of lower service life caused by thread damage has relatively large limitations. Contents of the invention [0003] The object of the present invention is to provide a synchronous bolt tightener for a large sealing cover, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a synchronous bol...
