[0002] With the continuous development of aerospace technology, the functional performance requirements of spacecraft are getting higher and higher, and the structure is becoming more and more complex. In particular, some large spacecraft, from satellites to lunar probes, have integrated many instruments and equipment. On the one hand, some instruments and equipment are becoming more and more sophisticated, and the assembly accuracy requirements are getting higher and higher; on the other hand, the structure of spacecraft is complex, and the difficulty of instrument assembly is increasing. At the same time, as the spacecraft has stronger functions, some special equipment has also been developed and applied, which has more stringent time and space requirements for assembly. For example, the isotope thermoelectric battery (RTG) used in the Chang'e-4 probe, as a nuclear product, is the first isotope nuclear source used in space in China. It is a key device for heat preservation and power supply for the Chang'e-4 lander on the moon night. Due to its radiation, heat and other characteristics, it must be installed on the day of launch. Since the rocket fairing has been closed at this time, the operating space is very small, the installation path is relatively complicated, it is easy to interfere with other equipment, and the installation accuracy requirements are high. Usually, when installing RTG, it is necessary to accurately avoid other easily interfering equipment in a limited space under the condition of insufficient light in the rocket fairing, and quickly move to the installation position for installation, and the forward path of RTG needs to be optimized.

The above-mentioned fixed frame and the connecting frame are both provided with weight reduction holes.

[0032] Generally, the slide rail assembly includes an optical axis vertically arranged on a connecting frame through a linear bearing. The fixing member is provided with a slot for connecting with the cabin board, and a bracket positioning pin is provided on the fixing member corresponding to the slot. When installing, the star cabin board can be directly connected to the slot.

[0034] The push rod is provided with a push rod locating pin, and the L-shaped frame is provided with a locating pin hole corresponding to the push rod locating pin. The designed position of the locating pin hole here means that when the push rod locating pin is fixed in the locating pin hole, it just reaches the limit position of the fixing frame. This position is accurately calculated during the design to ensure the installation accuracy.

[0035] The lifting and adjusting centering device is composed of a vertical motion pair through a linear bearing and a connecting rod mechanism. When the equipment is installed, it can achieve accurate and fast adjustment operations. It is easy to use and the RTG installation accuracy is high.

[0038] The horizontal stretching device includes a bottom plate 3-1 horizontally slidably arranged on a fixed frame, a transfer tool connecting plate 3-3 is slidably arranged on the bottom plate, and the transfer tool connecting plate and the bottom plate slide in the same direction relative to the connecting frame; usually, an upper guide rail 3-7 is arranged parallel to the upper surface of the bottom plate, and the transfer tool connecting plate is slidably arranged on the upper guide rail;

[0039] The transfer tooling includes a bottom panel 4-5, on which a sliding seat 4-2 is provided; the sliding seat is driven by a fine adjustment mechanism to slide in a direction perpendicular to the sliding direction of the bottom panel relative to the connecting frame. A push-pull handle 4-3 is provided on the bottom panel for easy installation and removal. A cable plug strap for fixing cables can be provided on the push-pull handle to facilitate cable restraint.

[0040] In the invention, a horizontal kinematic pair is formed by a horizontal linear guide rail and a limit mechanism, and a vertical kinematic pair is formed by a linear bearing and a connecting rod mechanism. The horizontal extension device is connected to the lifting and adjusting device, and carries the RTG transfer tooling. The base plate includes upper and lower linear guide rails, so that the base plate and the transfer tooling connecting plate can move horizontally. Among them, the base plate forms a lower horizontal kinematic pair through a guide rail slider and a bracket connecting plate, which can be horizontally extended and retracted, and can be positioned and locked in the extended and retracted states by the base plate locating pins installed on the bracket connecting plate; the transfer tooling connecting plate forms an upper horizontal kinematic pair through a guide rail slider and the base plate, and is positioned and locked in the extended state, the middle limit position, and the retracted state by the locating pins installed on the transfer tooling connecting plate. The locating pins therein adopt a spring pin structure.

[0041] In order to achieve a lightweight design, weight-reducing holes may be provided on the fixing frame, the connecting frame, and the bottom plate. Usually, the above-mentioned slide rail assembly includes a linear optical axis 2-10 vertically arranged on the connecting frame through a linear support 2-9, and a linear bearing 2-11 may be arranged on the fixing frame. The linear optical axis cooperates with the linear bearing, and when the height of the fixing frame is adjusted, the stability is good and the structural stability is high. The driving assembly can be used to drive the fixing frame to move up to a predetermined position. After it is in place, the push rod positioning pin 2-12 is used to lock the position, thereby maintaining the convenience of the RTG installation operation and a secure fixation.

[0042] The connecting frame comprises two symmetrically arranged C-shaped frames (a first C-shaped frame 2-1 and a second C-shaped frame 2-2), wherein the C-shaped frame comprises an upper connecting body and a lower connecting body; a fixing member 1 is provided at the end of each connecting body.

[0043] The fixing member is provided with a slot for connecting with the cabin board, and a bracket positioning pin is provided on the fixing member corresponding to the slot. After the satellite cabin board is matched with the slot, the bracket positioning pin can be directly used to fix it.

[0044] The fixed frame includes an L-shaped frame body corresponding to each C-shaped frame body, the two L-shaped frames are arranged back to back, the two L-shaped frames are fixed by a connecting base frame 2-14, and a horizontal stretching device is arranged above the connecting base frame.

[0045] In an optional embodiment, a U-shaped bracket with an upward opening may be provided between the fixing bracket and the connecting bracket, and the C-shaped frame and the L-shaped frame are fixed back to back on the vertical portion of the U-shaped bracket.

[0046] The above-mentioned driving assembly includes a push rod hingedly fixed at the lower part of each C-shaped frame; a connecting rod is provided on the push rod, one end of the connecting rod is hinged on the push rod (middle part), and the other end is hinged on the L-shaped frame; a rotating shaft is provided at the hinge point between the connecting rod and the push rod (it can also be that the connecting rod and the push rod are both rotatably connected to the rotating shaft 2-13, using the rotating shaft as the hinge point), and this rotating shaft connects the driving assemblies on both sides as a whole. Usually, the push rod can be provided with a third locking mechanism only on one side of the push rod. In addition, the push rod without the third locking structure can be replaced by a short rod 2-15, that is, one end of the short rod is hinged on the connecting frame, and the other end is hinged on the connecting rod, and there is no redundant protruding part, so as to prevent interference and make the structure more compact and reasonable.

[0047] The push rod is provided with a push rod locating pin, and a locating pin hole 2-16 is provided on the L-shaped frame corresponding to the push rod locating pin. It should be noted that the position of the locating pin hole is such that when the push rod locating pin is fixed in the locating pin hole, the fixed frame is just raised to the highest position. The "highest" mentioned here is relative to the "stroke" of the drive assembly, that is, the fixed frame is just at the extreme position.

[0048] The bottom plate is slidably arranged on the bracket connecting plate 3-2, and the bracket connecting plate is mounted on the fixing frame; a first locking mechanism for fixing with the bottom plate is arranged on the bracket connecting plate. A second locking mechanism 3-4 is arranged between the transfer tool connecting plate and the bottom plate.

[0049] Specifically, the first locking mechanism includes a positioning pin slidably set on the bracket connecting plate, and a limiting groove matching the positioning pin is provided on the bottom plate. Of course, the first locking mechanism may also include a locking screw, which is screwed on the bracket connecting plate to achieve fixation.

[0050] The second locking mechanism includes a connecting plate locating pin 3-6 arranged on the transfer tooling connecting plate, and a locking cam 3-5 is provided on the transfer tooling connecting plate (in fact, the locking cam can be pressed and fixed on the transfer tooling connecting plate by a screw that can be screwed and adjusted. By loosening the screw, the position of the locking cam relative to the connecting plate locating pin can be conveniently adjusted. When installing or removing the transfer tooling, the cooperation between the locking cam and the connecting plate locating pin is first released; and when the transfer tooling is installed and the RTG on the transfer tooling connecting tooling needs to be fixed, it is only necessary to adjust the locking cam so that it abuts against the connecting plate locating pin, and then fix the locking cam with a screw). After the locking cam abuts against the connecting plate locating pin, the transfer tooling can be locked (that is, the transfer tooling is fixed on the transfer tooling connecting plate to ensure that the two are firmly connected, and it is very easy to disassemble, and the assembly and disassembly efficiency is very high).

[0051] The above-mentioned fine-tuning mechanism includes a sliding base 4-4 arranged on the bottom panel, on which a sliding seat 4-2 is arranged, and the sliding seat is driven to move on the sliding base by a lateral adjustment rod 4-8.

[0052] It should be noted that transfer tooling locating pins 4-6 can be set on the bottom panel to push the RTG to move forward horizontally along the upper guide rail on the bottom plate to the limit position in the middle. At this time, the transfer tooling locating pins are automatically elastically dropped into the locating pin holes on the bottom plate. Pull open the bottom plate locating pins, push the bottom plate assembly forward along the lower guide rail to the positioning position, and at this time, the bottom plate locating pins are automatically elastically dropped into the locating pin holes on the bottom plate to lock, thus realizing the forward adjustment of the RTG.

[0053] The above-mentioned lateral adjustment rod includes a horizontally arranged rod body, one end of the rod body is threadedly connected to the sliding base, and the other end extends out of the sliding base; a convex ring 4-14 part that can resist the sliding seat is provided in the middle of the rod body, and a groove for accommodating the convex ring is provided on the sliding seat, and an end cover 4-10 is provided at the position corresponding to the groove on the outer side of the sliding seat, and the end cover limits the convex ring part of the rod body within the groove.

[0054] In order to facilitate the sliding adjustment of the sliding seat in a direction perpendicular to the guide rail, a handle can be provided at the free end of the rod body extending from the sliding base, and a hexagonal groove can be provided on the end surface of the free end. It can be manually screwed with the handle or screwed with a hexagonal wrench. When the adjusting rod rotates, it interacts with the threaded hole of the sliding base to move left and right, driving the sliding seat to translate left and right.

[0055] The above-mentioned sliding base is fixed on the bottom panel by installing screws. The height of the sliding base can be adjusted according to actual needs by adjusting the height adjustment screw 4-9 on the sliding base, which has better adaptability and higher RTG installation accuracy. The installation screw 4-13 is a connecting piece used to fix the sliding base on the bottom panel. The principle of the height adjustment screw is similar to that of the cover opening screw. Its lower end is against the bottom panel. It is screwed according to needs to fix the sliding base at a suitable height position. After adjusting the height of the sliding base, tighten the installation screw 4-13.

[0056] Specifically, four height adjustment screws are provided on the sliding base. After loosening the mounting screws 4-13 of the sliding base, the height adjustment screws 4-9 are adjusted to fine-tune the height and level of the sliding base. Tighten the mounting screws again to fasten the sliding base to the bottom panel.

[0057] Two groups of arc-shaped support plates 4-11 are arranged side by side on the above-mentioned sliding seat, and each arc-shaped support plate is provided with a binding webbing 4-12. The RTG is cylindrical and is matched and connected with an arc-shaped bracket and a binding webbing. In addition, a polytetrafluoroethylene pad can be provided on the upper surface of the arc-shaped support plate to avoid wear and tear between the RTG equipment 5. In an optional embodiment, handles 4-1 are detachably installed at both ends of the bottom panel. The handle is inserted into the card slot of the bottom panel from the outside and fixed by the handle locating pin 4-7 on the bottom panel. Removable fixation can be achieved, and the specific structural form can be selected according to actual needs.

[0058] The above-mentioned base plate is slidably arranged on the bracket connecting plate through a lower guide rail assembly, and the lower guide rail assembly includes two rows of lower guide rails 3-8 arranged in parallel at the bottom of the base plate, and a guide rail slide 3-9 matching each lower guide rail is provided on the bracket connecting plate.

[0059] When installing RTG on a spacecraft, there are four main processes, namely, installing RTG to the device, advancing RTG, ascending RTG, advancing RTG and installing. The installation method includes the following steps:

[0060] 1.RTG installation to the device

[0061] When installing the RTG, use the transfer tool to transfer the RTG, and install the RTG and the transfer tool together on the transfer tool connection plate from the rocket fairing operation port. When installing the RTG, you must first stretch the RTG loader to the extended state, so that the sliding bottom plate is close to the fairing operation port, which is convenient for the RTG transfer tool to be installed on the bottom plate. Note that the locking cam needs to be rotated to the unlocked state.

[0062] After the RTG is installed in the loading device, pull out the handle positioning pin, remove the transfer tooling handles on both sides, and rotate the locking cam to lock the transfer tooling.

[0063] 2.RTG advances

[0064] RTG advancement includes a two-step advancement process.

[0065] The first step is to push the push-pull handle on the transfer tooling to push the RTG to move horizontally forward along the upper guide rail of the bottom plate to the limit position in the middle. At this time, the transfer tooling locating pin automatically falls into the locating pin hole on the bottom plate under the elastic force.

[0066] The second step is to pull open the bottom plate positioning pin and push the bottom plate assembly forward along the lower guide rail to the positioning position. At this time, the bottom plate positioning pin automatically falls into the positioning pin hole on the bottom plate under the elastic force and is locked.

[0067] 3. RTG rises

[0068] After the RTG moves forward, it is already behind the interference device and will not interfere with the device when it rises to the installation position. At this time, the push rod of the (connecting rod) driving mechanism of the lifting and lowering adjustment device is pushed to the positioning position of the positioning pin hole, and the push rod positioning pin is locked and positioned. At this time, the RTG is already at the installation position.

[0069] 4.RTG advance and install

[0070] At this time, continue to push the handle to make the RTG move forward along the bottom plate guide rail so that the RTG pin hole matches the pin shaft on the lander. After moving forward close to the cabin plate, initially tighten the screws on the top of the RTG (without adding torque).

[0071] In the installation device provided by the invention, multiple connection structures adopt a screw-free quick disassembly and assembly method, which is easy to operate and prevents the generation of excess materials. The overall stability and reliability can avoid the risk of equipment collision. At the same time, the installation path is combined with the movement of the mechanism to make the installation operation faster and more efficient. This device uses the spacecraft equipment installation cabin as a reference, eliminates the collision risk caused by the shaking of the spacecraft or rocket body relative to the external reference, makes the equipment docking more accurate and stable, and the designed fine-tuning mechanism can make accurate and quick adjustments when the equipment is installed and positioned. At the same time, a variety of quick assembly and disassembly methods are designed, which can be applied to a variety of connection and positioning needs.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
