Description

Maintenance dock column for aircraft maintenance

technical field

The utility model belongs to the technical field of aircraft maintenance docks, in particular to a maintenance dock column for aircraft maintenance.

Background technique

For the fixed aircraft maintenance dock, if the operation surface platform of the aircraft maintenance dock wants to realize the lifting action, it is all done through the maintenance dock column. After a period of aircraft maintenance operations, the operation surface platform has experienced several Reciprocating lifting, the lifting drive assembly in the maintenance dock column may be damaged, so the lifting drive assembly needs to be repaired, but at this time the problem has arisen. According to previous design experience, in order to ensure the support strength of the maintenance dock column, the maintenance dock The main body of the column is designed as a closed cage structure, and the lifting drive assembly is set inside the cage structure. It is almost impossible to directly disassemble the lifting drive assembly for repair. The only way to do it is to repair the entire maintenance dock column first. Disassembly, and then disassembly of the lifting drive assembly, and the entire disassembly process is very inconvenient, resulting in a lot of time and manpower for each repair operation, even after the lifting drive assembly is repaired, the lifting drive assembly needs to be installed back in the maintenance dock column , causing the installation process to take a lot of time and manpower again. Therefore, it is urgent to design a maintenance dock column with a new structure. On the premise of ensuring the support strength of the maintenance dock column, it can simplify the disassembly and installation process of the lifting drive assembly, which is convenient The maintenance of the dock column saves time and labor costs.

Utility model content

Aiming at the problems existing in the prior art, the utility model provides a maintenance dock column for aircraft maintenance, which can simplify the disassembly and installation process of the lifting drive assembly, facilitate the maintenance of the maintenance dock column, and save time and labor costs.

In order to achieve the above object, the utility model adopts the following technical scheme: a maintenance dock column for aircraft maintenance, including a base frame, a track, a slider guide frame and a lifting drive assembly, the base frame adopts an open triangular structure, and the track Vertically arranged in the middle of the base frame, the slider guide frame is located on the track, and a lifting support frame for connecting the working surface platform is installed on the slider guide frame; the slider guide frame cooperates with the rail lift through the lifting drive assembly .

The lifting drive assembly includes a drive motor, a worm gear box, a lead screw and a screw nut, the drive motor is fixedly mounted on the top of the base frame, the motor shaft of the drive motor is connected with the worm gear box through a coupling, and the lead screw is vertical Set, and the upper end of the lead screw is connected with the worm gear box, and the screw nut is fixedly mounted on the slider guide frame through the mounting seat and is also sleeved on the lead screw.

Several guide wheels are installed on the slider guide frame, and the guide wheels are in rolling contact with the track.

The beneficial effects of the utility model:

Compared with the prior art, the utility model breaks the customary design idea, abandons the traditional closed cage structure, and adopts an open triangular structure for the maintenance dock column as a whole, which not only ensures that the maintenance dock column has sufficient supporting strength, It also greatly simplifies the disassembly and installation process of the lifting drive assembly, facilitates the maintenance of the maintenance dock column, and saves a lot of time and labor costs during the loading and unloading process.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figures 1, 2, 3, and 4, a maintenance dock column for aircraft maintenance includes a base frame 1, a track 2, a slider guide frame 3 and a lifting drive assembly, and the base frame 1 adopts an open triangular shape. structure, the track 2 is vertically arranged in the middle of the base frame 1, the slider guide frame 3 is located on the track 2, and the lift support frame 4 for connecting the working surface platform is installed on the slider guide frame 3; the slider guide frame Frame 3 cooperates with track 2 lifting by lifting drive assembly. the

The lifting drive assembly includes a drive motor 5, a worm gear box 6, a lead screw 7 and a screw nut 8, the drive motor 5 is fixedly mounted on the top of the base frame 1, and the motor shaft of the drive motor 5 is connected to the worm gear box 6 through a coupling. Connected, the lead screw 7 is vertically arranged, and the upper end of the lead screw 7 is connected with the worm gear box 6, and the screw nut 8 is fixed on the slider guide frame 3 through the mounting seat and is also sleeved on the lead screw 7.

A plurality of guide wheels 9 are installed on the slider guide frame 3 , and the guide wheels 9 are in rolling contact with the track 2 .

Adopting the maintenance dock of the utility model, there are four maintenance dock columns under the working surface platform, the working surface platform is connected with the maintenance dock column through the lifting support frame 4, the driving motor 5 is started, and the screw 7 is driven to rotate through the worm gear box 6 , the screw nut 8 is driven to move up and down by the rotation of the lead screw 7, and then the slider guide frame 3 is driven to move up and down, thereby realizing the lifting action of the working surface platform. During the working process of the lifting drive component, since there is no shelter, the running status of the lifting drive component can be clearly observed, which facilitates daily inspection operations. Compared with the traditional closed cage structure, once the lifting drive component is found to be damaged, it is especially necessary When replacing the lead screw 7, the whole lead screw 7 can be easily disassembled only by first disassembling the slider guide frame 3, and the installation of the lead screw 7 is also convenient and simple, which saves a lot of time and labor costs.
