Description

Technical Field

[0001] This utility model relates to the field of satellite side panel assembly auxiliary tools, and in particular to a side panel vehicle for satellite side panel assembly. Background Technology

[0002] my country is a major space power, and the country invests heavily in space exploration. Currently, our satellite program is experiencing rapid development. With the evolving situation, the requirements for satellite assembly are becoming increasingly stringent, necessitating rapid assembly and disassembly while ensuring safety.

[0003] Similar to large satellites, small satellites also often have individual units mounted on side panels. During installation, the side panels, along with the individual units, are then mounted onto the main structural frame of the satellite. Currently, many small satellites have integrated electronic units that need to be mounted on side panels due to the heat dissipation requirements of their thermal control design. However, because these integrated electronic units play a core role in the various subsystems of the satellite, there are a considerable number of low-frequency and high-frequency cables leading to them. Furthermore, each unit typically weighs between 6 and 10 kg, making satellite installation extremely difficult and posing certain risks, such as cable compression on the satellite. On the other hand, due to the characteristics of small satellites, the length of the cable network is strictly controlled. This prevents the side panel with the unit mounted from being laid flat for electrical testing, as this would require even longer cables. The conventional method is to manually lift the entire side panel (including the unit), rotate it to a vertical position, and perform satellite installation and cable connection operations. In most cases, due to the complexity of the cable connections, the operator needs to hold the side panel for extended periods, which is highly detrimental to the final assembly operation and carries certain risks.

[0004] To address this, we designed a side panel assembly vehicle for satellite side panels. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a side panel vehicle for assembling satellite side panels.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A side panel assembly vehicle for satellite side panels, comprising:

[0008] The mobile vehicle has legs that can move up and down to facilitate the transfer of the satellite side panel to the initial position and then fix the position of the mobile vehicle; the rear end of the mobile vehicle has a lifting handle to facilitate the pushing and pulling of the mobile vehicle by staff of different heights; the top of the mobile vehicle has a cross slide.

[0009] A lifting device is provided on the sliding part of the cross slide to facilitate adjustment of its front-back and left-right positions via the cross slide;

[0010] A base frame is provided on the lifting part of the lifting device to facilitate height adjustment via the lifting device;

[0011] The mounting frame is installed on the base frame via an adjustment system to fix the satellite side panel, so that the satellite side panel can be adjusted to the final installation position via the adjustment system.

[0012] The mounting frame is provided with multiple interfaces for connecting satellite side panels at intervals along its circumference.

[0013] Preferably, the adjustment system includes:

[0014] A front-to-back linear adjustment assembly is correspondingly located between the front end of the base frame and the bottom of the mounting frame to facilitate adjustment of the front-to-back position of the bottom of the mounting frame;

[0015] An elevation angle adjustment component is correspondingly disposed between the base frame and the mounting frame to facilitate adjustment of the elevation angle of the mounting frame;

[0016] The movable part of the elevation angle adjustment component is connected to the base frame via a ball joint.

[0017] Preferably, the adjustment system further includes:

[0018] The vertical straight adjustment component is located between the front end of the base frame and the bottom of the mounting frame, and is used to adjust the vertical position of the bottom of the mounting frame.

[0019] The fixed part of the front and rear linear adjustment component is correspondingly provided on the moving part of the upper and lower linear adjustment component, or the fixed part of the upper and lower linear adjustment component is provided on the moving part of the front and rear linear adjustment component.

[0020] Preferably, the adjustment system further includes:

[0021] A left-right linear adjustment component is correspondingly located between the front end of the base frame and the bottom of the mounting frame, and is used to adjust the left-right position of the bottom of the mounting frame;

[0023] Preferably, the linear adjustment assembly is provided in two sets, which are respectively located on the left and right sides of the bottom of the mounting frame;

[0024] The linear adjustment assembly includes a rotatable straight rod inserted into a corresponding component and a drive component that drives the straight rod to move axially.

[0025] Preferably, the linear adjustment assembly further includes a locking element capable of locking the axial position of the straight rod.

[0026] Preferably, the elevation angle adjustment component includes:

[0027] The rotating seat is correspondingly hinged to the base frame;

[0028] The movable rod is axially movable and connected to the rotating seat.

[0029] The upper end of the movable rod is hinged to the mounting frame.

[0030] Preferably, the movable rod is a threaded rod, the rod body of which is threadedly fitted with a threaded sleeve, and the threaded sleeve is rotatably connected to the rotating seat.

[0035] 2. The mobile vehicle and lifting equipment enable the satellite side panel to be moved to the initial installation position;

[0036] 3. The cross slide can further adjust the front-to-back and left-to-right position of the satellite side panel, thus effectively increasing the gap between the initial moving satellite side panel and the satellite, preventing the personnel from being unable to brake the moving vehicle in time, which could lead to a collision between the satellite side panel and the satellite.

[0037] 4. The system settings allow for six degrees of freedom adjustment of the satellite side panel position, ensuring that the satellite side panel moves to the optimal installation posture. Specifically, the forward and backward linear adjustment components, vertical linear adjustment components, and elevation adjustment components are connected to the base frame via ball joints. This allows for adjustment of the vertical roll angle of the installation frame by adjusting a single forward and backward linear adjustment component, and adjustment of the vertical yaw angle of the installation frame by adjusting a single vertical linear adjustment component.

[0044] Example 1, in conjunction with Appendix Figure 1-4 A side panel vehicle for assembling satellite side panels, comprising:

[0045] The mobile vehicle 1 has vertically movable support legs 11 to facilitate the transfer of the satellite side panel to the initial position and then fix the position of the mobile vehicle 1; the rear end of the mobile vehicle 1 has a lifting handle 12 to facilitate the pushing and pulling of the mobile vehicle 1 by staff of different heights; the top of the mobile vehicle 1 has a cross slide 13.

[0046] As needed, the mobile vehicle body 1 can be a U-shaped structure, with wheels at the front and rear ends of each side of the U-shaped structure; as needed, each rear end and / or front end of each side of the U-shaped structure is provided with a support leg 11;

[0047] In one possible implementation, the support leg 11 includes a vertical screw threaded to the moving vehicle body 1, and the lower end of the vertical screw is provided with a support body; as needed, the support body can be fixedly installed at the lower end of the vertical screw, or it can be rotatably connected to the lower end of the vertical screw.

[0048] A handle may be provided at the upper end of the vertical screw, depending on the requirements.

[0049] Specifically, the cross slide 13 can be adjusted in two directions: forward and backward, and left and right.

[0050] In one possible implementation, the lifting handle 12 includes two vertical sleeves spaced apart to the left and right. Each vertical sleeve is fitted with a lifting rod extending from its upper end, and both lifting rods have a handle at their upper ends. Further, a locking bolt perpendicular to the upper end of each vertical sleeve is threaded onto it. The locking bolt abuts against the lifting rod, fixing the height of the lifting rod. Depending on the needs, the handle can be a rod positioned to the left and right, with its left and right ends connected to the upper ends of the corresponding lifting rods.

[0051] The lifting device 2 is located on the sliding part of the cross slide 13 so that its front-back and left-right positions can be adjusted by the cross slide 13.

[0052] Depending on the needs, the lifting device 2 can be a commonly used device in existing technologies such as an electric telescopic rod or a cylinder, which will not be described in detail here.

[0053] The base frame 3 is located at the lifting part of the lifting device 2 so that its height can be adjusted by the lifting device 2;

[0054] Mounting frame 4 is installed on base frame 3 via adjustment system to fix satellite side plate, so that the attitude of satellite side plate can be adjusted to the final installation position via adjustment system.

[0055] The mounting frame 4 has multiple interfaces for connecting satellite side panels at intervals along its circumference.

[0056] As required, the installation frame 4 adopts a U-shaped frame structure.

[0057] In one possible implementation, the adjustment system includes:

[0058] The front and rear linear adjustment component 5 is located between the front end of the base frame 3 and the bottom of the mounting frame 4 to facilitate adjustment of the front and rear position of the bottom of the mounting frame 4.

[0059] The elevation adjustment component 6 is positioned between the base frame 3 and the mounting frame 4 to facilitate adjustment of the elevation angle of the mounting frame 4; that is, the A-axis angle of the mounting frame 4 is adjusted via the elevation adjustment component 6.

[0060] The moving part of the elevation adjustment component 6 is connected to the base frame 3 via a ball joint.

[0061] In one possible implementation, the elevation adjustment assembly 6 includes a rotating seat 61 correspondingly hinged to the base frame 3 and a movable rod 62 whose rod body is axially movably connected to the rotating seat 61.

[0062] The upper end of the movable rod 62 is hinged to the mounting frame 4.

[0063] When the upper end of the movable rod 62 is rotatably connected to the mounting frame 4 via a universal ball joint, the movable rod 62 can be threadedly engaged with the rotating seat 61; the universal ball joint rotatable connection can be understood as the movable rod 62 being able to rotate relative to the mounting frame 4 along its own central axis without angular limitation; that is, the axial movement is achieved by rotating the movable rod 62 along its central axis.

[0064] When the upper end of the movable rod 62 is rotatably connected to the mounting frame 4 only through a ball joint, the movable rod 62 can be a threaded rod with a threaded sleeve threaded into the rod body, and the threaded sleeve is rotatably connected to the rotating seat 61; the ball joint rotatable connection can be understood as the movable rod 62 being able to rotate only at a small angle relative to the mounting frame 4 along its own central axis, that is, the axial movement of the movable rod 62 is driven by the rotation of the threaded sleeve.

[0065] Furthermore, to facilitate the rotation of the threaded sleeve, the rotating base 61 is also rotatably connected to a rotating handwheel 63 arranged on the left and right, and the rotating rod of the rotating handwheel 63 is engaged with the threaded sleeve through a gear set or a worm gear set. Preferably, the rotating rod of the rotating handwheel 63 is engaged with the threaded sleeve through a worm gear set.

[0066] As needed, the base frame 3 has a downwardly extending extension 31 in the middle, and the elevation adjustment component 6 is correspondingly hinged to the lower end of the extension 31.

[0067] As needed, the adjustment system may also include an upper and lower linear adjustment component 7, which is disposed between the front end of the base frame 3 and the bottom of the mounting frame 4, and is used to adjust the upper and lower position of the bottom of the mounting frame 4.

[0068] The front and rear linear adjustment component 5 is fixed to the upper and lower linear adjustment component 7, or the upper and lower linear adjustment component 7 is fixed to the front and rear linear adjustment component 5.

[0069] As needed, the adjustment system may also include a left and right linear adjustment component 8, which is disposed between the front end of the base frame 3 and the bottom of the mounting frame 4, and is used to adjust the left and right position of the bottom of the mounting frame 4.

[0070] The front and rear linear adjustment component 5 is fixed and correspondingly disposed on the left and right linear adjustment component 8 moving part, or the left and right linear adjustment component 8 is fixed and disposed on the front and rear linear adjustment component 5 moving part.

[0071] Furthermore, the linear adjustment assembly includes a rotatable straight rod inserted into a corresponding component and a drive member for driving the straight rod to move axially.

[0072] Furthermore, the straightness adjustment assembly also includes a locking element capable of locking the axial position of the straight rod.

[0073] As needed, front-to-back linear adjustment components 5, up-to-down linear adjustment components 7, and left-to-right linear adjustment components 8 are provided between the front left and right sides of the base frame 3 and the bottom left and right sides of the mounting frame 4.

[0074] It should be noted that when only one front and rear linear adjustment component 5 is adjusted, the mounting frame 4 can be rotated around the vertical line at a small angle by the rotation of the straight rod of the upper and lower linear adjustment component 7 and the action of the ball joint; that is, the B-axis angle of the mounting frame 4 is adjusted.

[0075] It should be noted that when only one vertical linear adjustment component 7 is adjusted, the mounting frame 4 can be rotated around the front and rear linear axis by the rotation of the straight rod of the front and rear linear adjustment component 5 and the action of the ball joint; that is, the C-axis angle of the mounting frame 4 can be adjusted.

[0076] It should be noted that the movable rod 62 can move left and right relative to the mounting frame 4. In one possible embodiment, the upper end of the movable rod 62 has a ball bearing, and the mounting frame 4 is provided with a straight rod that slides left and right through the ball bearing.

[0077] In this example, for ease of understanding, we will take an adjustment system that includes a front-to-back linear adjustment component 5, an elevation adjustment component 6, a vertical linear adjustment component 7, and a horizontal linear adjustment component 8 as an example. Specifically, the front-to-back linear adjustment component 5 is fixed at the front end of the mounting frame 4, the vertical linear adjustment component 7 is fixed at the moving part of the front-to-back linear adjustment component 5, and the horizontal linear adjustment component 8 is fixed at the moving part of the vertical linear adjustment component 7.

[0078] The front and rear linear adjustment assembly 5 includes front and rear sleeves 51 fixedly connected to the front end of the base frame 3. The rear ends of the front and rear sleeves 51 are threaded with front and rear lead screws 52. The front and rear sleeves 51 are rotatably inserted with front and rear straight rods 53, and the front and rear lead screws 52 and the front and rear straight rods 53 are rotatably connected. That is, by rotating the front and rear lead screws 52, the front and rear lead screws 52 can move forward and backward or backward under the action of the front and rear sleeves 51, thereby driving the corresponding side of the mounting frame 4 to move forward and backward or backward.

[0079] As needed, the front and rear sleeves 51 are also screwed with locking bolts 54 along their radial direction. The rotation of the locking bolts 54 presses the front and rear straight rods 53, thereby fixing the position of the front and rear straight rods 53. That is, the straight rod of the front and rear linear adjustment assembly 5 is the front and rear straight rods 53, the driving component is the combination of the front and rear sleeves 51 and the front and rear lead screws 52, and the locking component is the locking bolts 54.

[0080] The vertical linear adjustment assembly 7 includes upper and lower sleeves 71 fixedly mounted at the front end of the front and rear straight rods 53, and upper and lower screws 72 passing through the upper and lower sleeves 71. Nuts 73 are provided at positions above and below the upper and lower sleeves 71 on the body of the upper and lower screws 72. That is, by rotating the nuts 73, the upper and lower screws 72 move up and down, thereby driving the corresponding side of the mounting frame 4 to move up and down. In other words, the straight rods of the vertical linear adjustment assembly 7 are the upper and lower screws 72, the driving component is the combination of the upper and lower sleeves 71 and the nuts 73, and the locking component is the nuts 73; that is, the nuts 73 are both part of the driving component and the locking component.

[0081] The left-right straight line adjustment component 8 can adopt the same structure as the up-down straight line adjustment component 7, with only the orientation being different, which will not be described in detail here.

[0082] It should be noted that the working principle of the layout where the upper and lower straight adjustment component 7 is fixed at the front end of the mounting frame 4, the front and rear straight adjustment component 5 is fixed at the moving part of the upper and lower straight adjustment component 7, and the left and right straight adjustment component 8 is fixed at the moving part of the upper and lower straight adjustment component 7; or the layout where the left and right straight adjustment component 8 is fixed at the front end of the mounting frame 4, the upper and lower straight adjustment component 7 is fixed at the moving part of the left and right straight adjustment component 8, and the front and rear straight adjustment component 5 is fixed at the moving part of the upper and lower straight adjustment component 7 is the same as the above example, and will not be described in detail here.

[0083] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
