Problems solved by technology

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. down, it's inconvenient
There are also potential safety hazards when workers operate on the stair-type auxiliary support. If they are not careful, they will easily fall or break parts, which will affect the assembly speed and assembly quality.
Furthermore, there are many parts in such an assembly site, and it is easy to cause confusion in site management.

Embodiment 1

[0017] As a preferred embodiment of the present invention, such as figure 1 . A pit 14 is arranged under the ground of the factory building, and a lifting device 23 is installed in the pit 14, and a lifting platform 5 is fixedly connected to the lifting device 23 . Said lifting platform 5 is provided with an assembly frame 2 for assembling the engine and an auxiliary assembly frame 3, and the assembly frame 2 can rotate 360° along its supporting axis. The engine assembly is first assembled on the auxiliary assembly frame 3, and then moved to the assembly frame 2 to be assembled with other components. The lifting device 23 can be a variety of hydraulic or mechanical transmissions, such as figure 1 , figure 2 , image 3 shown. figure 1 The lifting device 23 is composed of a worm gear mechanism 9, a gear box 10 and a motor 11. The lifting platform 5 is set on the two screw rods 12 with a nut 13. The lifting platform 5 is also provided with rollers and guide rails 6. The low...

Embodiment 2

[0019] Another preferred embodiment of the present invention is figure 2 , and the other structures remain unchanged. Described lifting device 23 is made up of high-pressure oil pump 15, oil tank 16, two sets of support rods 17, and hydraulic cylinder 18. A hydraulic guide rail 24 is fixedly connected to the lifting platform 5, and a horizontal guide rail 25 is also fixed on the pit 14 and the base 8. One end of two sets of four support rods 17 is respectively fixed on the hydraulic guide rail 24 and the lateral guide rail 25, 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 driving motor 22 drives the high-pressure oil pump 15, and the high-pressure oil is delivered to the actuator cylinder 18, which pushes the actuator cylinder to generate axial displacement, and drives the support rod 17 to move bidirectionally so that the lifting platform 5 moves up and down...

Embodiment 3

[0021] Mounting frame of the present invention also can adopt such elevating mechanism, see image 3 . Described lifting device 23 is made up of gear 20 , rack 21 and driving motor 22 . There are four racks 21 inherent on the wall of the pit, and four gears 20 inherent on the lifting platform 5 . Drive motor 22 drives four gears 20 on the lifting platform 5 to roll on the four racks 21 installed vertically to achieve the purpose of lifting.

[0022] When the assembly work starts, the worker opens the pit cover 4, automatically lifts the assembly frame 2 from the pit 14 to the ground through the operating mechanism, fixes it when it reaches the required height, and starts the assembly work. The lifting platform 5 and the assembly frame 2 can be automatically lowered to below the ground, and the cover plate 4 is covered to form a level 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...
