Example Embodiment

[0019] Example 1

[0020] As a preferred embodiment of the present invention, such as figure 1 . A pit 14 is provided under the ground of the factory building. A lifting device 23 is installed in the pit 14 and a lifting platform 5 is fixedly connected to the lifting device 23. The lifting platform 5 is provided with an assembly frame 2 for assembling an engine and an auxiliary assembly frame 3, and the assembly frame 2 can rotate 360° along its supporting axis. The engine components are assembled on the auxiliary assembly frame 3 first, and then moved to the assembly frame 2 to be assembled with other components. The lifting device 23 can be hydraulic or mechanical multiple transmission modes, such as figure 1 , figure 2 , image 3 Shown. figure 1 The lifting device 23 in the middle is composed of a worm gear mechanism 9, a gear box 10 and a motor 11. The lifting platform 5 is sleeved on the two screws 12 with a nut 13. The lifting platform 5 is also provided with rollers and...

[0021] Example 2

[0022] Another preferred embodiment of the present invention figure 2 , The other structure remains unchanged. The lifting device 23 is composed of a high-pressure oil pump 15, an oil tank 16, two sets of support rods 17, and a hydraulic actuator 18. The lifting platform 5 is fixedly connected with a hydraulic guide rail 24, and a horizontal guide rail 25 is also inherent in the pit 14 and the base 8. Two sets of four support rods 17 are fixed to the hydraulic guide rail 24 and the transverse guide rail 25 at one end, and the other ends are fixed respectively. On the base 8 and the lifting platform 5, the hydraulic guide rail 24 moves up and down with the lifting platform 5. The drive motor 22 drives the high-pressure oil pump 15, and the high-pressure oil is delivered to the actuator cylinder 18. The actuator cylinder is pushed to produce axial displacement, and the support rod 17 is driven to move bidirectionally to make the lifting platform 5 move up and dow...

Example Embodiment

[0023] Example 3

[0024] The assembly frame of the present invention can also adopt such a lifting mechanism, see image 3 . The lifting device 23 is composed of a gear 20, a rack 21 and a driving motor 22. Four racks 21 are built on the wall of the pit, and four gears 20 are built on the lifting platform 5. The driving motor 22 drives the four gears 20 on the lifting platform 5 to roll on the four racks 21 installed vertically to achieve the purpose of lifting.

[0025] When the assembly work starts, the worker opens the pit cover 4, and the assembly frame 2 is automatically raised from the pit 14 to the ground through the operating mechanism. When it reaches the required height, it is fixed and the assembly work starts. After the assembly work is completed, the operating mechanism is used The lifting platform 5 and the assembly frame 2 can be automatically lowered below the ground together, and the cover plate 4 can be covered to form a flat ground.

Abstract

A lift frame for assembling engine is composed of a ground pit, a lift mechanism installed in said ground pit and consisting of lift platform, base, motor, gear box, worm-gear mechanism, screw bolt and nut, and an assembling frame on said lift platform.

Description

technical field [0001] The invention relates to an assembly frame, in particular to an assembly frame for the general assembly of an aero-engine. technical background [0002] During the general assembly of the aero-engine, it needs to be carried out on an assembly frame. The assembly frame that is used at present mostly adopts the fixed or movable assembly bracket that is arranged on the ground to complete the general assembly of the engine. Due to the large diameter and length of the engine, during assembly, workers have to use staircase-type auxiliary supports to continuously change the height and install the components and parts one by one. The tools, equipment and parts used for assembly must be sent manually. It's very inconvenient. There are also potential safety hazards when workers operate on the staircase-type auxiliary support. If they are not careful, they will easily hurt their bodies or break parts, which affects the assembly speed and assembly quality. Furt...
