The mounting platform is installed above the tiltable rotating platform, and the tiltable rotating platform carries the mounting platform with the attached casing for fine angle adjustment.

[0008] It also includes an X / Y moving platform that can move in the X and Y directions in the horizontal plane with the installation platform, and the X / Y moving platform is installed below the tiltable and rotatable platform.

[0009] It also includes a Z-axis lifting platform that can be finely adjusted and raised with the mounting platform, which is installed below the X / Y moving platform.

[0010] It also includes the transfer vehicle body that serves as a load-bearing support, with the Z-axis lifting platform installed on the transfer vehicle body.

[0011] The bottom of the transfer vehicle is equipped with wheels that allow it to roll; a handle that is fixed to the front end of the transfer vehicle is used for pushing.

[0012] The beneficial effects of this invention are as follows: the fly attachment housing is raised to a suitable installation position by the lifting mechanism, the horizontal position of the fly attachment housing is finely adjusted by rotating the Z-axis lifting platform and the adjustment handle of the X / Y moving platform, the fly attachment housing is finely adjusted at multiple angles by the tiltable rotating platform, and finally the fly attachment housing is installed on the pull rod, thus solving the problem of not being able to finely adjust the angle of the fly attachment housing.

Detailed Implementation

[0014] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0015] like Figures 1 to 2 As shown.

[0016] This application discloses a multi-functional installation and transfer vehicle for aircraft engine attachment casings, comprising: The transfer vehicle body 6, which serves as a support for the load, is equipped with wheels 61 at each of the four corners of its bottom, which can be omnidirectional brake rollers; a handle 62 for pushing and bearing is fixed to the front end of the transfer vehicle body 6.

[0017] It also includes a lifting mechanism 1 installed on the transfer vehicle body 6, which can lift the installation platform 5; the lifting mechanism 1 is a hydraulic lifting mechanism or a pneumatic lifting rod, with an adjustable height of 1000mm; the use of a hydraulic lifting mechanism facilitates self-locking, and the use of a handle switch for oil unloading.

[0018] The lifting mechanism 1 is equipped with a Z-axis lifting platform 2, which can perform fine-tuning and lifting of the mounting platform 5. The Z-axis lifting platform 2 is a screw jack for small-range adjustment and uses a worm gear drive with a self-locking function. An adjustment handle is designed, and the platform is driven by a handwheel. The moving distance is 50mm, the load capacity is 1t, the screw is Tr30×6 with a reduction ratio of 12:1, and the lifting stroke is 0.5mm per revolution of the handwheel.

[0019] The Z-axis lifting platform 2 is equipped with an X / Y moving platform 3, which can move the mounting platform 5 in the X and Y directions in the horizontal plane. The X / Y moving platform 3 is adjusted by a combination of manual screw and valve blocks, with an adjustment handle for small-range adjustment in the horizontal direction, with an adjustment accuracy of 0.5mm. Limiting and locking blocks are set at the front and rear to limit the extreme positions of the slider.

[0020] The X / Y moving platform 3 is equipped with a tiltable and rotating platform 4, which can rotate freely in the horizontal direction, such as... Figure 2 The dotted line indicates rotation; the mounting platform 5 is detachably and fixedly connected to the tiltable rotating platform 4, which allows for fine-tuning of the angle of the mounting platform 5, which carries the mounting casing. The tiltable rotating platform 4 uses a precision shaft worm gear transmission mode, which can be linked with other platforms. The diameter of the rotating platform is Φ320mm, the screw transmission ratio is 1:120, and an adjustment handle is designed, with an adjustment range greater than 10°.

[0021] The installation platform 5 is a work platform that can be replaced with different types of mounting bases according to the on-site usage scenario. This work platform can be equipped with different types of mounting bases to carry out the installation and transportation of different types of fly attachment casings, motors and hydraulic pumps.

[0022] The installation sequence for the attachment housing is as follows: First, use the dedicated attachment housing lifting tool to secure the main mounting lugs and lift the attachment housing out of the packaging box. Second, secure the mounting base to the installation transport vehicle by connecting the mounting studs on the installation platform 5 to the attachment housing transfer interface. Remove the dedicated attachment housing lifting tool; at this point, the attachment housing is fixed on the installation transport vehicle. Finally, move the installation transport vehicle to a position directly below the suspension platform for installation.

[0023] When the installation transfer vehicle moves the fly attachment receiver to the area directly below the suspension platform for installation, the fly attachment receiver is first raised to a suitable installation position by the lifting mechanism 1. The horizontal position of the fly attachment receiver is then finely adjusted by rotating the adjustment handles of the Z-axis lifting platform 2 and the X / Y moving platform 3. The fly attachment receiver is then finely adjusted at multiple angles by using the tiltable rotating platform 4. Finally, the fly attachment receiver is installed on the tie rod, which solves the problem of not being able to finely adjust the angle of the fly attachment receiver.
