technical field

The utility model relates to the field of a fixing device, in particular to a generator fixing device.

Background technique

As one of the important applications of diesel engine, diesel generator set consists of three parts: diesel engine, mounting plate and generator. Usually, due to the different generators equipped by different users, the structural dimensions of the mounting plate are also different. For different generators, in order to meet the concentric installation of the generator and the diesel engine, the mounting plate needs to be modified, which not only increases the cost, but also prolongs the installation time.

The application number is CN202221262468.4, and the patent document titled "A Fixing Device for Adjustable Diesel Generator Set" discloses a fixing device that can adjust the height of the generator set. The depth of the adjusting block screwed into the threaded hole of the base varies; when the axis of the generator is higher than the crankshaft of the diesel engine, turn the adjusting block clockwise to lower the height of the axis of the generator; when the axis of the generator is higher than the crankshaft of the diesel engine When the shaft center is low, turn the adjusting block counterclockwise to raise the shaft center height of the generator; until the diesel engine meets the requirements; tighten the two fixing nuts according to the specified tightening torque to complete the fixed installation of the generator. Since the conventional generator base and the mounting plate are fixedly connected through the cooperation of bolts and nuts, and the mounting holes on the generator base and the mounting plate are all through holes, the technical solution recorded in the above patent needs to have threaded holes on the mounting plate, so Using the fixing device described in the above-mentioned patents requires machining threaded holes on the mounting plate. Although it is convenient to concentrically adjust the generator and diesel engine, the mounting plate still needs to be refitted.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

As shown in Figure 1-4, a generator fixing device includes a double-ended screw 3, the double-ended screw 3 runs through the mounting hole of the mounting plate 1 and the generator base 2, and a socket is inserted into the mounting hole of the mounting plate 1 6. The lower end of the sleeve 6 is plugged into the kit 4, and the upper end of the kit 4 is tightly against the lower end of the mounting plate 1.

The double-ended screw 3 below the sleeve 4 is provided with a through hole 5 , and the axial direction of the through hole 5 is perpendicular to the axial direction of the double-ended screw 3 .

A lower backing ring 7 is fixed on the upper end of the plug sleeve 6 , and the lower backing ring 7 is integrally formed with the plug sleeve 6 . A sleeve 4 is threaded on the double-ended screw 3 below the socket 6 , and an upper backing ring 8 is threaded on the lower backing ring 7 . The upper end of the lower backing ring 7 is provided with a threaded hole, and the lower end of the upper backing ring 8 is processed with a convex ring, and the convex ring is threadedly connected with the threaded hole of the lower backing ring 7 .

An inner sleeve 10 is plugged into the installation hole of the generator base 2, and a gasket 9 is fixed on the upper end of the inner sleeve 10, and the inner sleeve 10 and the gasket 9 are integrally formed. The double-ended screw rod 3 above the gasket 9 is threaded with a nut 11, the double-ended screw rod 3 runs through the gasket 9, the inner sleeve 10, the upper backing ring 8, the lower backing ring 7, the sleeve 6 and the kit 4, and the double-ended screw rod 3 It is threadedly connected with socket 6.
