A device for rapid positioning and installation of an aero-engine on a ground test bed

Abstract

The application discloses a device for quickly positioning and installing an aero-engine ground bench, which comprises a device for fixing and limiting a rotatable main joint bearing on the engine. The rotatable main joint bearing on the engine is fixed by a small positioning buckle, so that the main joint bearing is limited and subjected to force for being lifted, thereby solving the problem that an operator needs to support and limit the rotatable main joint bearing, and improving the efficiency of the engine on the bench.

Description

Technical Field

[0001] This invention relates to a device for rapid positioning and installation on a ground test bench for aero engines, belonging to the field of aero engine technology. Background Technology

[0002] When installing an aero engine on a ground test bench, the main joint bearing is rotatable and lacks a positioning function. As a result, the operators need to limit and support the rotatable main joint bearing during the engine installation, which is labor-intensive and reduces the efficiency of engine installation. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a device for rapid positioning and installation on a ground test bench for aero-engines.

[0004] The present invention is achieved through the following technical solutions.

[0005] This invention provides a device for rapid positioning and installation on a ground test bench for aircraft engines, comprising:

[0006] A device that can fix the rotatable main joint bearing on the engine and limit the force.

[0007] Includes: suspension beams;

[0008] Large positioning buckle, which is fixed to the lifting beam. The lower part of the large positioning buckle has an opening with a chamfer.

[0009] The small positioning buckle is installed on the large positioning buckle. During installation, the small positioning buckle secures the rotatable main joint bearing on the engine.

[0010] The lifting beam is equipped with lifting rings that are hooked to the lifting equipment for hoisting.

[0011] The lifting beam has openings for adjusting the installation position of the lifting rings.

[0012] The lifting beam is fixedly equipped with front and rear lifting lugs.

[0013] An auxiliary positioning adjustment rod is fixed on the end of the lifting beam away from the large positioning buckle to assist in the installation of the auxiliary tie rod.

[0014] The beneficial effects of this invention are as follows: the rotatable main joint bearing on the engine is fixed by a small positioning buckle, so that the main joint bearing is limited and can be lifted by force, which solves the problem that it is laborious and time-consuming for operators to limit and support the rotatable main joint bearing, and improves the efficiency of engine loading.

[0017] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0018] like Figure 1 As shown.

[0019] This application discloses a device for rapid positioning and installation on a ground test bench for aircraft engines, comprising:

[0020] The main load-bearing beam 4 is equipped with a lifting ring 1 via a telescopic component. After the lifting ring 1 is hooked to the lifting equipment, the beam 4 is suspended. The beam 4 is installed on the lifting ring 1 in an adjustable manner via the telescopic component, ensuring that the height of the beam 4 is adjustable.

[0021] The large positioning buckle 2, which is fixed to the lifting beam 4, has an opening on its lower section with a chamfer at the opening. The large positioning buckle 2 is used to fasten the main load-bearing pin mounting seat to connect with the engine's main load-bearing pin.

[0022] The small positioning buckle 3, installed on the large positioning buckle 2, fixes the rotatable main joint bearing on the engine during installation, thereby limiting the main joint bearing and allowing it to be lifted under force. This solves the problem of the labor-intensive and time-consuming process of limiting and supporting the rotatable main joint bearing, and improves the efficiency of engine mounting.

[0023] The lifting beam 4 has openings for adjusting the installation position of the lifting ring 1, and is suitable for installation of various engine models.

[0024] The lifting beam 4 is equipped with a front lifting lug 6 and a rear lifting lug 7, which are used to lift both ends of the engine.

[0025] An auxiliary positioning adjustment rod 5 is fixedly installed on the end of the lifting beam 4 away from the large positioning buckle 2. The auxiliary positioning adjustment rod 5 is aligned with the position of the auxiliary mounting point support plate on the engine. The auxiliary tie rod is fixed to the position of the auxiliary mounting point support plate of the engine by the auxiliary positioning adjustment rod 5.
