[0002] There is a unit shock absorber as a vibration reduction element between the installation of the rail transit air-conditioning unit and the car body. One end of the unit shock absorber is installed on the installation foot of the air-conditioning unit, and the other end is installed on the car body. This requires that the installation hole group can be well matched with the unit and the car body.

[0003] Normally, the shock absorber is pre-installed on the mounting feet of the air conditioning unit and ensures a high installation accuracy, so that it can be installed in one step without adjustment. The mounting feet are usually 6 or 8, and the number of mounting holes involved is 12 or 16. In order to ensure the positioning accuracy of the mounting hole group, the assembly accuracy of the shock absorber and the mounting feet must be guaranteed. Usually, this installation requires manual measurement and control of the dimensions while tightening the bolts to prevent misalignment during assembly, and usually requires two people to cooperate in the operation to ensure the assembly accuracy requirements. It is inefficient, time-consuming and labor-intensive, and has poor dimensional stability. Summary of the invention

[0038] The limit baffle 2 is a vertically bent structure, and includes a fourth portion 21 and a fifth portion 22. The fourth portion 21 and the fifth portion 22 are vertically arranged, the fourth portion 21 is arranged in contact with the first portion 11, the fifth portion 22 is arranged perpendicular to the first portion 11, and the fifth portion 22 is arranged on the inner side of the first portion 11 relative to the fourth portion 21.

[0039] The position of the limit baffle 2 on the first part 11 can be adjusted according to the size of the shock absorber 6, and the adjustment range is 170-190 mm.

[0040] The two limit baffles 3 are respectively arranged on the second portion 14 and the third portion 15 . The limit baffles 3 are arranged on the surfaces of the second portion 14 and the third portion 15 facing the first portion 11 . The two limit baffles 3 are arranged opposite to each other.

[0045] Based on the above structure, please refer to Figure 1 In the specific implementation, the shock absorber 6 is installed in the frame 1 of the quick positioning and installation device. Under the action of gravity, the lower surface of the shock absorber 6 contacts the inner upper surface of the frame 1, which plays a role in vertical positioning. At the same time, the positioning pin 12 penetrates the mounting holes at both ends of the lower mounting plate of the shock absorber 6 to play a role in longitudinal positioning. The shock absorber 6 is gently pushed back so that the rear edge of the lower mounting plate of the shock absorber 6 contacts the adjustment limit stopper 3 to play a role in lateral positioning. At this point, the degrees of freedom of the shock absorber 6 in the quick positioning and installation device are all constrained.

[0046] Install the quick positioning installation device containing the vibration damper 6 onto the installation foot 5 of the air conditioning unit, as shown in FIG. Figure 1 As shown, the rear of the vibration damper 6 quick positioning installation device contacts the side of the air-conditioning unit part 7, playing a role in lateral positioning. The two left and right limit baffles 2 at the opening on the upper surface of the frame 1 in the quick positioning installation device are inserted into the two longitudinal end surfaces of the air-conditioning unit mounting foot 5, playing a role in longitudinal positioning. Afterwards, the clamp 4 is manually operated so that the two pressure heads 41 of the clamp 4 respectively press the upper surface of the air-conditioning unit mounting foot 5. Due to the squeezing of the clamp 4, the quick positioning installation device containing the vibration damper 6 will move upward until the upper surface of the upper mounting plate of the vibration damper 6 contacts the lower surface of the mounting foot 5. Continue to press the clamp 4, and the quick positioning installation device containing the vibration damper 6 will move further upward. After the clamp 4 is pressed into place, under the action of the quick mounting device, the vibration damper 6 in the device is firmly pressed in the quick mounting device in the vertical direction. At this point, the vertical direction is positioned. After being completely positioned and constrained in the horizontal, longitudinal and vertical directions, the device has been firmly and accurately fixed on the mounting foot 5 of the air conditioning unit, and the hands can be separated from the quick positioning and installation device, and then a single person can perform the bolt tightening operation to quickly, easily and accurately install the shock absorber 6 on the mounting foot 5 of the air conditioning unit. When disassembling, only the tightener 4 needs to be loosened to quickly remove the positioning and installation device.

[0047] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope.
