Be used for vertical bottom plate to go up screw rod pretightning force and screw up auxiliary device

Technical Field

The application relates to an auxiliary device is screwed up to screw rod pretightning force on being used for vertical bottom plate belongs to mechanical industry's overhaul of equipments and installation technique.

Today, advanced manufacturing represented by large airplanes, large power generation equipment, automobiles, high-speed trains, large ships, large complete sets and the like is about to enter an important development direction. Thus, the fastener will enter an important stage of development. The high-strength bolt is used for connection of important machinery, and repeated disassembly and assembly or various mounting torque methods have extremely high requirements on the high-strength bolt.

In order to improve the installation stability of the equipment components, the existing equipment component installation method is to fixedly connect the equipment with the bottom plate through high-strength bolts, and to transmit the force applied to the equipment components in the using process to the bottom plate. In order to improve the bearing capacity of the bottom plate, an iron bottom plate is generally selected as a mounting bottom plate, screw mounting holes are formed in the bottom plate, and the mounting type of the bottom plate is divided into a transverse bottom plate, namely the bottom plate, which is laid at intervals in the horizontal direction, and a vertical bottom plate, namely the bottom plate, which is laid at intervals in the radial direction. When the equipment parts are installed, the high-strength bolt penetrates through the screw rod installation hole to be connected with the equipment parts on the other side, and then the bolt is screwed, namely, the fastening process is completed.

The existing construction object is high-strength screw pre-tightening force construction on a vertical iron bottom plate, and as the tightening torque of the pre-tightening force of the high-strength screw is large, a manual torque wrench or a hydraulic torque wrench is adopted for tightening so that the tightening torque of each screw reaches a standard value. In order to improve the construction progress, the existing construction method adopts a hydraulic torque wrench to replace a manual torque wrench to perform screw pre-tightening, and because the vertical bottom plate is of a smooth structure, stress points are lacked on the bottom plate, the vertical bottom plate can not be used as a leaning surface of a reaction arm of the hydraulic torque wrench, and when the screw at a high position is screwed, due to height limitation, an operator can not perform manual operation, so that the hydraulic torque wrench can not be adopted to perform screw pre-tightening on the vertical bottom plate. Therefore, when the bolts on the vertical bottom plate which is at a certain height from the ground are screwed down, the conventional method is to set up a steel pipe frame or a construction platform from the ground to the screw pre-tightening construction height, and constructors manually utilize a manual torque wrench to pre-tighten the screws. However, the method is time-consuming, labor-consuming, unchanged in movement and not suitable for large-area construction. Or welding or punching are carried out on the vertical bottom plate to install the auxiliary piece as the abutting surface of the reaction arm of the hydraulic torque wrench, but the method needs to carry out welding or punching for many times so as to correspond to the screw rods at different positions. The working efficiency is low, the iron bottom plate can be damaged, and the subsequent construction is not influenced. Therefore, a new stress device is needed to solve the problem of pre-tightening construction of the screw on the vertical iron bottom plate.
