[0052] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0053] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 as well as Figure 5 As shown, an integrated transfer device for satellite loading provided by the present invention includes a transfer vehicle 1, a limit lifting mechanism 4 and a box 3. The limit lifting mechanism 4 is used to fasten the transfer vehicle 1 and the box 3. The transfer vehicle 1 includes a trolley bracket 6, a wheel set 13 and a lifting mechanism 8; the satellite product 2 is fastened to the trolley bracket 6, and multiple wheel sets 13 are respectively provided at the front bottom and rear bottom of the trolley bracket 6; the lifting mechanism 8 includes a drive assembly and a lifting caster 16. The drive assembly drives the lifting caster 16 to rise or fall in the vertical direction relative to the trolley bracket 6, and the lifting mechanism 8 is provided with multiple groups behind the wheel set 13 at the front bottom of the trolley bracket 6, and the lifting mechanism 8 is provided with multiple groups behind the wheel set 13 at the rear bottom of the trolley bracket 6.

[0054] like Figure 2 and Figure 3 As shown, specifically, the trolley bracket 6 includes a frame 11 and a protective bracket 12. The protective bracket 12 is arranged on the peripheral side of the frame 11. One protective bracket 12 is fastened and installed at the front and rear of the frame 11 respectively. Both the frame 11 and the protective bracket 12 are welded from aluminum alloy square tube profiles. A vibration detection recorder is provided on the frame 11. The vibration detection recorder of the present application preferably adopts a Shocklog vibration detection recorder, which is used to record the vibration of the detection box 3. Two wheel sets 13 are symmetrically arranged at the front bottom of the frame 11, and two wheel sets 13 are symmetrically arranged at the rear bottom of the frame 11, and any wheel set 13 is connected to the frame 11 by bolts.

[0055] like Figure 2 、 Figure 3 as well as Figure 4As shown, the transfer vehicle 1 also includes a vibration reduction system 7, which includes a vibration reduction spring 14 and a satellite mounting plate 15. One end of the vibration reduction spring 14 is connected to the satellite mounting plate 15, and the other end of the vibration reduction spring 14 is connected to the vehicle bracket 6. The vibration reduction springs 14 are symmetrically arranged at a 45-degree angle to opposite sides, and the connection surface of the satellite product 2 is fastened to the satellite mounting plate 15 via fasteners, which facilitates stability during parking. The satellite mounting plate 15 is connected to the satellite product 2 via a process ring, and the mounting surface of the satellite mounting plate 15 is uniformly distributed with multiple mounting holes. A feasible embodiment is: the mounting surface of the satellite mounting plate 15 is uniformly distributed with 48 mounting holes, which are M8 threaded circular holes, with the starting hole position at the quadrant line position. The mounting surface of the satellite mounting plate 15 is 155mm to 160mm above the lower edge of the wheel assembly 13.

[0056] like Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 as well as Figure 8 As shown, the transfer vehicle 1 also includes a satellite bracket protection device 10, which is positioned between the vibration reduction system 7 and the trolley bracket 6. The satellite bracket protection device 10 includes a fixing bolt 21, a spacer 22, and a rubber pad 23. The fixing bolt 21 connects the trolley bracket 6 and the satellite mounting plate 15. The spacer 22 and rubber pad 23 are respectively positioned on the upper and lower sides of the satellite mounting plate 15 and are in contact with the satellite mounting plate 15. The satellite bracket protection device 10 is used to prevent accidents caused by damage to the vibration reduction spring 14 and provides secondary protection for the satellite. A set of satellite bracket protection devices 10 are provided on both sides of each vibration reduction spring 14.

[0057] A guide rail 5 is provided in the box body 3. The guide rail 5 allows the transfer vehicle 1 to move along the direction of the guide rail 5, and a limit hole is provided on the guide rail 5. The transfer vehicle 1 also includes a limit device 9. The limit device 9 includes a limit rod 19 and a guide cylinder 20. The limit rod 19 is coaxially passed through the guide cylinder 20, and one end of the limit rod 19 is set downward. When the limit rod 19 moves to the top of the limit hole, the limit rod 19 relies on its own gravity to insert into the limit hole for limitation. It should be noted that the maximum length of the limit rod 19 inserted into the limit hole is less than the maximum lifting height of the transfer vehicle 1 by the lifting caster 16.

[0058] After the limiting rod 19 is inserted into the limiting hole to generate a limit, the lifting mechanism 8 is used to raise the transfer vehicle 1 until the limiting rod 19 is completely out of the limiting hole, and then the vehicle can be pushed to continue moving along the guide rail 5. In a feasible embodiment of the present application, two sets of limiting devices 9 are respectively provided at the front and rear of the vehicle frame 11, and each set of limiting devices 9 is located above the guide rail 5.

[0059] like Figure 2 and Figure 5As shown, the drive assembly includes a lift 17 and a crank handle 18. The lift 17 includes a vertically arranged movable rod, and the lift caster 16 is disposed at the bottom end of the movable rod. The crank handle 18 is in driving connection with the lift 17. Clockwise rotation of the crank handle 18 drives the lift caster 16 upward, while counterclockwise rotation of the crank handle 18 drives the lift caster 16 downward. Alternatively, clockwise rotation of the crank handle 18 drives the lift caster 16 downward, while counterclockwise rotation of the crank handle 18 drives the lift caster 16 upward.

[0060] It should be further explained that the rocking handle 18 and the lift 17 of the present application are combined to form a manual lifting device, which is common in the prior art, and the driving component of the present application mainly drives the lifting caster 16 to rise or fall in the vertical direction relative to the trolley bracket 6. The lifting mechanism 8 in the prior art that can achieve this effect falls within the protection scope of the present application.

[0061] like Figure 8 、 Figure 9 as well as Figure 10 As shown, the transfer vehicle 1 further includes a position-limiting lifting mechanism 4, which includes a front wedge 24 and a rear wedge 25. The front wedge 24 includes a front slider 26 and a front stopper 27. The front slider 26 is fastened to the front of the trolley support 6, and the front stopper 27 is fastened to the frame of the box 3, with the front slider 26 and the front stopper 27 abutting each other. The rear wedge 25 includes a rear slider 28 and a rear stopper 29. The rear slider 28 is fastened to the rear of the trolley support 6, and the rear stopper 29 is fastened to the frame of the box 3, with the rear slider 28 and the rear stopper 29 abutting each other. When the front slider 26 and the front stopper 27 abut in place, the transfer vehicle 1 moves into position within the box 3. At this time, the front slider 26 and the front stopper 27 are fastened together using bolts.

[0062] Furthermore, a preferred technical solution is that when the transfer vehicle 1 moves into position in the box body 3, the four limiting rods 19 on the frame 11 are all inserted into the limiting holes to generate a limit.

[0063] The present invention also provides a method for transferring an integrated transfer device for satellite loading, using the integrated transfer device for satellite loading, and the method comprises the following steps:

[0064] S1. Fasten and install the satellite product 2 on the transfer vehicle 1.

[0065] S2. Push the transfer vehicle 1 until the wheel set 13 is horizontally aligned with the guide rail 5.

[0066] S3. Adjust the height of the wheel set 13 to be equal to the height of the guide rail 5 through the lifting mechanism 8.

[0067] S4. Push the transfer vehicle 1 into the box body 3. When the limit rod 19 reaches the top of the limit hole, the limit rod 19 falls into the limit hole. Adjust the height of the trolley bracket 6 through the lifting mechanism 8 until the limit rod 19 completely disengages from the limit hole, and continue to push the trolley into the box body 3.

[0068] S5. After the front sliding block 26 on the transfer vehicle 1 contacts the front stopper 27, fasteners are used to fasten the front sliding block 26 and the front stopper 27 together.

[0069] For step S4, during the process of pushing the transfer vehicle 1 into the box body 3, the limit rod 19 located at the front of the frame 11 is inserted into the limit hole, and the height of the frame 11 is adjusted by the lifting mechanism 8 until the limit rod 19 is completely out of the limit hole, and the trolley continues to be pushed. The height of the two lifting casters 16 located at the front of the frame 11 is adjusted by the lifting mechanism 8 so that the wheel group 13 contacts the guide rail 5 until the wheel group 13 at the rear of the frame 11 completely enters the box body 3, and the two lifting casters 16 located at the rear of the frame 11 are retracted by the lifting mechanism 8, and the trolley continues to be pushed until the front slider 26 contacts the front stopper 27.
