The invention provides an auxiliary installation mechanism for a large nut. The auxiliary installation mechanism for the large nut is characterized by comprising a supporting block, a supporting hydraulic cylinder rod, a supporting hydraulic cylinder piston, a supporting hydraulic cylinder body, a threaded lead screw, a large nut lifting hook, a lead screw lifting hook and a thrusting nut. The supporting hydraulic cylinder body is sleeved on the threaded lead screw. One end of the supporting hydraulic cylinder rod extends into the supporting hydraulic cylinder body to form a movable hydraulic cylinder structure together with the supporting hydraulic cylinder body. One end, extending out of the supporting hydraulic cylinder body, of the supporting hydraulic cylinder rod is provided with the supporting block. The end, extending into the supporting hydraulic cylinder body, of the supporting hydraulic cylinder rod is connected with the supporting hydraulic cylinder piston inside the supporting hydraulic cylinder body. The thrusting nut is installed at the non-screwing end of the threaded lead screw and tightly abuts against the supporting hydraulic cylinder body. According to the auxiliary installation mechanism for the large nut, due to the fact that a small threaded hole or a taper hole is formed in the shaft which the nut is installed on, the large nut can center more easily when being installed. By means of the threaded lead screw, the nut can be screwed in more easily when being installed. Being supported by a hydraulic cylinder, the auxiliary installation mechanism for the large nut is simple and convenient to operate.
Description
technical field [0001] The invention relates to a nut installation mechanism, in particular to the installation of large nuts with large volume and difficult centering. Background technique [0002] During the installation process of the blades of large turbines and compressors, it is often necessary to use large nuts for reinforcement and positioning. During the installation process of such large nuts, due to their large size, alignment is often very difficult, which will greatly weaken the factory. Productivity. Contents of the invention [0003] Purpose of the invention: The present invention provides an auxiliary installation mechanism for large nuts, the purpose of which is to solve the problems of difficult centering and screwing in of the above-mentioned large nuts during the installation process. [0004] Technical solution: the present invention is achieved through the following technical solutions: [0005] A large nut auxiliary installation mechanism is chara...
