Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of satellite assembly, in particular to a satellite assembly manual right-angle tilting support vehicle. BACKGROUND

[0002] In the assembly process of commercial micro-satellites, the handling and assembly operation of parts have high precision and stability requirements, and the reliability of the whole machine assembly platform and the attitude requirement of the satellite test process are also strict.

[0003] At present, most of the support vehicles on the market are fixed and cannot be turned over, or are manually hydraulic support vehicles, which can only complete simple horizontal transportation and cannot realize satellite right-angle tilting. During the assembly of commercial micro-satellites, parts or components often need to be assembled at right angles. Manual adjustment is not only difficult to be accurate in angle, but also easy to cause assembly deviation and affect the performance of the satellite, and is low in efficiency, which restricts the assembly progress.

[0004] In addition, the traditional horizontal transportation method makes the center of mass of the satellite high, increasing the risk of transportation, and although large automatic tilting equipment can adjust the angle, it is high in cost, complex in operation and requires professional maintenance personnel. SUMMARY

[0005] Therefore, it is necessary to provide a satellite assembly manual right-angle tilting support vehicle which can be manually tilted at right angles and is simple to operate.

[0006] A satellite assembly manual right-angle tilting support vehicle, comprising a base, a support frame is arranged on the base; a winch is arranged on one side of the support frame, and an assembly platform is hingedly arranged on the upper end edge of the other side; The assembly platform is connected with the winch through a rope, and the assembly platform is driven to rotate around the hinge shaft by winding or unwinding the rope by operating the winch.

[0007] In one embodiment, the winch is two, and the two winches are symmetrically arranged along the longitudinal central axis.

[0008] In one embodiment, the winch is a labor-saving bidirectional self-locking winch.

[0009] In one embodiment, the two winches share a handle; and / or the surface of the shared handle is designed to be slip-resistant.

[0010] In one embodiment, a limiting piece is further arranged; the limiting piece is arranged on the support frame and located near the end of the hinge shaft, and the rotation angle is limited by the limiting piece.

[0011] In one embodiment, a support frame is arranged on one side along the length direction of the base, and the other side is a rotation accommodating area; a buffer is arranged on the support frame on the side facing the rotation accommodating area.

[0012] In one embodiment, the buffer is a rubber buffer, and / or a polyurethane buffer, and / or a silica gel buffer, and / or a spring rebounder.

[0013] In one embodiment, a counterweight platform is arranged on the base, and the counterweight platform is located below the support frame; according to the change of the center of mass of the satellite, a counterweight is placed on the counterweight platform.

[0014] In one embodiment, wheels are arranged below the base.

[0015] In one embodiment, an inclined brace is further arranged at the junction of the support frame and the base.

[0016] Compared with the prior art, the satellite assembly manual right-angle tilting support vehicle provided by the application has the following effects: 1. The assembly platform can realize a right-angle tilting of 0° to 90° by manually operating the winch to wind and unwind the rope, which facilitates the operator to assemble, detect or debug the satellite from the horizontal and vertical directions, reduces the number of workpiece handling times, and improves the utilization rate of work station space. At the same time, the tilting angle of the assembly platform can be steplessly adjusted by manually operating the winch to wind and unwind the rope, which meets the operation requirements of different tilting angles in the satellite assembly process. Compared with electric driving, manual control is easier to realize micro-adjustment and control is more accurate.

[0017] 2. The assembly platform is connected with the support frame through a hinged shaft to form a stable rotation fulcrum, the center of gravity offset during tilting can be controlled, platform shaking or overturning is avoided, and the attitude stability of the satellite parts during tilting is ensured. In addition, the rope as a flexible connecting piece can buffer the impact force when the winch starts and stops during transmission, and reduce the vibration or impact caused by rigid transmission.

[0018] 3. The structure is simple, the operation is convenient, the manufacturing and maintenance cost is low, and the vehicle is easy to disassemble and transport, which is suitable for cross-site operation requirements in satellite assembly. BRIEF DESCRIPTION OF DRAWINGS

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1 to 6 As shown, the satellite assembly manual right-angle tilting support vehicle provided in this embodiment includes a base 1, on which a support frame 2 is provided; a winch 3 is provided on one side of the support frame 2, and an assembly platform 4 is hinged to the upper edge of the other side; the assembly platform 4 and the winch 3 are connected by a rope 5, and by operating the winch 3 to raise and lower the rope 5, the assembly platform 4 is driven to rotate around the hinge axis.

[0030] Specifically, the base 1 is rectangular, consisting of a frame composed of two shorter horizontal bars and two longer vertical bars. The horizontal bars and vertical bars are detachably connected, and end caps 6 are provided at the open ends of the horizontal bars and / or vertical bars for closure. It is worth noting that the detachable connection methods include, but are not limited to, snap-fit ​​connections, threaded connections, pin connections, and plug-in connections, which can be selected flexibly according to the situation. For example, when using a snap-fit ​​connection, a corresponding slot and snap-fit ​​are provided in the connecting part; when using a threaded connection, a corresponding threaded hole is provided in the connecting part, and then bolts are used for fixing; other connection methods are correspondingly provided with connecting components, which will not be elaborated here. Furthermore, the detachable connection mentioned later has the same meaning and will not be elaborated further. In this embodiment, the fixing using angle brackets and bolts is mainly used as an example for illustration, but it is only one feasible method and not the only limitation.

[0031] A counterweight platform 11 is provided on the base 1. As shown in the figure, the counterweight platform 11 is located below the support frame 2, near the winch 3. The counterweight platform 11 is mainly used to hold the counterweight. The counterweight platform 11 can be an added crossbar as shown in the figure. The number of crossbars and the spacing between the crossbars are designed according to the size of the counterweight to ensure that the counterweight can be placed stably. Alternatively, a plate structure can be provided, depending on the requirements. When the center of gravity of satellite 7 changes, a counterweight is placed on the counterweight platform 11 to balance the overall center of gravity position of the support vehicle and satellite 7, ensuring that the support vehicle remains stable during tilting and avoiding the risk of overturning or assembly accuracy errors caused by the shift of the center of gravity.

[0032] Wheels 12 are also installed below the base 1, located at the four corners of the rectangle and secured with bolts. Additionally, wheels 12 can be added to the longitudinal rod as needed to improve flexibility. The wheels 12 are preferably omnidirectional casters, which allow for flexible movement even in narrow assembly workshops, adapting to the limited workspace of commercial microsatellite assembly workshops. Furthermore, high-precision braking devices are installed on two or more wheels 12. These high-precision braking devices enable precise positioning, ensuring the stability of the support vehicle when stationary and preventing displacement during handling and tilting.

[0033] Along the length of the base 1, a support frame 2 is installed on one side, and a tilting and accommodating area is located on the other side. The main function of the support frame 2 is to connect the base 1 and the assembly platform 4, while the tilting and accommodating area provides a accommodating space for the tilted satellite 7. For ease of description, the side with the support frame 2 is considered the right side, and the side with the tilting and accommodating area is considered the left side. Furthermore, to ensure the balance of the center of gravity between the assembly platform 4 and the base 1, the support frame 2 and the tilting and accommodating area can be symmetrically arranged along the length of the base 1, and can be adjusted using counterweights to accommodate changes in mass when necessary.

[0034] The support frame 2 is a frame consisting of four uprights and four crossbars. The crossbars are connected to the upper ends of the uprights via angle brackets and bolts; the lower ends of the uprights are connected to the base 1 via angle slots. In the middle area of ​​the base 1, near the two uprights on the left side of the support frame 2, a crossbar is also provided to enhance the base 1's resistance to deformation. The crossbar on the base 1 is also fixed to the base 1 via a detachable connection.

[0035] At the bottom of the support frame 2, at the junction with the base 1, a diagonal brace 23 is also provided. One end of the diagonal brace 23 is connected to the upright of the support frame 2, and the other end is connected to the longitudinal bar of the base 1, forming a diagonal support. The diagonal brace 23 is detachably connected to the upright of the support frame 2 and the longitudinal bar of the base 1. One or more diagonal braces 23 are provided depending on the situation; in this embodiment, four are provided.

[0036] A winch 3 is installed on the side of the support frame 2 away from the tilting and receiving area, and the connection method is detachable. Specifically, there are two winches 3, which are symmetrically arranged along the longitudinal central axis of the base 1. The winches 3 are detachably connected to the crossbar on the support frame 2 away from the tilting and receiving area via a connector 24. The connector 24 is made of ordinary galvanized steel or stainless steel and is an integrally formed or welded irregular structure. One end of the connector is detachably connected to the crossbar on the support frame 2 away from the tilting and receiving area, and the other end is detachably connected to the winch 3.

[0037] Winch 3 is a labor-saving, two-way self-locking winch with a built-in hook and wire rope. It's a mature racking product on the market, featuring two-way self-locking, labor-saving operation, and easy installation. Models like the 1200LB or 1800LB are available, so its structure will not be described in detail here. Through the gears and bearings in winch 3, precise angle transmission is achieved, enabling smooth tilting of the assembly platform. Both winches 3 share a common handle 31; and / or the surface of the common handle 31 is designed with anti-slip features for easy application of force by the operator.

[0038] An assembly platform 4 is hinged to the upper edge of the support frame 2 near the flipping accommodating area. Specifically, the assembly platform 4 is connected to the support frame 2 via hinges 41. The hinges 41 are made of high-strength alloy steel and are heavy-duty hinges. They are fixed by a detachable connection. In this embodiment, screw holes and countersunk screws are used for fixing. The number of hinges 41 is set according to the situation; in this embodiment, three are used. By setting the hinges 41, the upper end of the support frame 2 near the flipping accommodating area is regarded as the hinge axis, thereby enabling the assembly platform 4 to achieve a right-angle flipping function based on the hinge axis and ensuring the smoothness and stability of the rotation.

[0039] The assembly platform 4 is similar in shape to the base 1, consisting of a rectangular frame composed of two shorter horizontal bars and two longer vertical bars. The horizontal and vertical bars are detachably connected, and end caps 6 are provided at the open ends of the horizontal and / or vertical bars for closure. The center of gravity of the assembly platform 4 is located near the hinge axis, and the area near the center of gravity is referred to as the center of gravity region 43. Mounting components for connecting the satellite 7 are provided on the upper surfaces of the horizontal and vertical bars. The satellite 7 is fixed to the assembly platform 4 by the mounting components. The mounting components are not shown in the figure; they are conventional components that connect to the satellite 7 and will not be described in detail here. It can be understood that the number and position of the mounting components are determined according to the mounting points on the satellite 7. During installation, it is necessary to ensure that the center of gravity of the satellite 7 is located in the center of gravity region 43 of the assembly platform 4 as much as possible. This can avoid the risk of tipping over, ensure the safety of the satellite 7, and ensure the overall stability of the structure. On the other hand, it can minimize the hand cranking force and improve the labor-saving effect. It is worth noting that the centroid region 43 can be marked, for example, by setting a centroid region plate or a centroid region crossbar, thereby forming a visual reference mark. This eliminates the need for complex measuring tools or repeated trial-and-error adjustments; initial positioning can be completed through visual alignment, improving assembly efficiency. In this embodiment, a centroid region plate is used for marking.

[0040] On the assembly platform 4, near the right-side crossbar, there is another crossbar. On the lower surface of this crossbar are two lifting rings 42, made of stainless steel. The hooks of the self-locking, two-way power-saving winch are connected to the two lifting rings 42. The rope connecting the assembly platform 4 and the winch 3 is the steel wire rope provided with the winch, thus connecting the winch 3 and the assembly platform 4. During operation, the winch 3 is operated to raise and lower the rope 5, driving the assembly platform 4 to rotate around the hinge axis. It is worth noting that, in addition to the crossbar connecting the lifting rings 42, other crossbars can be installed to enhance the stability of the assembly platform 4.

[0041] In addition, the horizontal bars, vertical bars, and columns on the base 1, support frame 2, and assembly platform 4 are all made of aluminum profiles, which are combined and fixed by the cooperation of aluminum profiles with corner brackets, corner grooves, and bolts.

[0042] Limiting components 21 are provided on the support frame 2. These limiting components 21 are located near the ends of the hinge shaft, and there may be one or two of them. When there is only one, it is provided at either end of the hinge shaft; when there are two, it is provided at both ends of the hinge shaft. The limiting component 21 is a screw, made of ordinary galvanized steel or stainless steel, and is used in conjunction with a T-bolt. When adjusting the tilt angle of the assembly platform 4, the rotation angle is limited by loosening and tightening the limiting component 21.

[0043] A buffer element 22 is provided on the side of the support frame 2 facing the tilting and receiving area. The buffer element 22 can be a rubber buffer element, and / or a polyurethane buffer element, and / or a silicone buffer element, and / or a spring rebounder. Specifically, the buffer element 22 is provided on the two columns facing the tilting and receiving area, respectively at the upper and lower ends of the two columns; for example, a rubber buffer element can be provided at the upper end of the two columns and a spring rebounder can be provided at the lower end of the two columns; alternatively, a polyurethane buffer element can be provided at the upper end of the two columns and a spring rebounder can be provided at the lower end of the two columns; the specific configuration depends on the actual situation and is not limited to the examples given in this embodiment. The buffer element 22 is mainly used to buffer the impact force generated when the satellite 7 tilts to a right angle, playing a buffering and protective role, avoiding structural damage caused by rigid contact, and extending the service life of the support vehicle. The buffer element 22 is connected to the support frame 2 by welding, gluing, or screws.

[0044] Furthermore, on the support frame 2, there are two handrails 25 on the crossbar on the side away from the flipping and accommodating area. They are symmetrically arranged on the crossbar along the longitudinal central axis of the base 1. The handrails 25 are mainly used as grippers during operation to facilitate the control of the movement of the support vehicle.

[0045] The satellite assembly manual right-angle tilting support vehicle designed in this invention uses aluminum profiles combined with corner brackets, corner grooves, and bolts for overall structure fixation, effectively reducing overall weight while ensuring structural strength. The assembly platform 4 and the support frame 2 are connected by hinge 41 to realize the tilting function.

[0046] During assembly, first assemble the base 1 and tighten the brakes on the wheels 12. Then, fix the support frame 2 onto the base 1. Next, hinge the assembly platform 4 to the crossbar on the side of the support frame 2 closest to the tilting and receiving area. Adjust the overall structure to ensure the support vehicle is sturdy, tilts smoothly and reliably, and the overall structure is safe. Then, place the assembly platform 4 horizontally, placing the center of gravity of the satellite 7 as close as possible to the center of gravity area 43. Then, fix the satellite 7 onto the assembly platform 4 using mounting components. This connection method increases the safety of the handling and tilting processes, avoiding damage caused by collisions or slippage of parts.

[0047] When satellite 7 needs to be moved horizontally, release the brake on wheel 12 and push the support vehicle to the designated position. When tilting is required, apply force through the common handle 31 to retract or extend the rope 5, causing satellite 7 to tilt. Observe the angle, and when it approaches the required angle, use the limiting device 21 to limit the tilt.

[0048] When tilting, the winch 3 provided in this embodiment, together with the common handle 31, and through the leverage effect of the hinge 41, combined with the center of mass area 43 specified on the assembly platform, can minimize the force required for tilting, thus achieving the purpose of easy and labor-saving tilting.

[0049] During the tilting process, the center of mass of satellite 7 moves forward and lowers. During this process, based on the weight of satellite 7, it is determined whether additional counterweights need to be added to the counterweight platform 11 below winch 3; or, after the tilting is completed, it is checked whether additional support pillars need to be added to the tilting containment area to increase satellite safety. The entire tilting process is manually operated, eliminating the need for complex electric drive systems and automated control devices, significantly reducing equipment costs and maintenance difficulty. This makes it particularly suitable for production scenarios with strict cost control, such as the final assembly of commercial microsatellites.

[0050] As can be seen, this invention, through the cooperation of the winch 3 and the limiting component, enables operators to conveniently and accurately achieve right-angle tilting of the assembly platform, improving the efficiency and accuracy of component angle adjustment during assembly, and contributing to the improvement of assembly quality and performance of commercial microsatellites. Furthermore, the tilting function effectively lowers the center of mass of the entire satellite, improving safety during handling and increasing the convenience of process testing.

[0051] In addition, the assembly platform 4 provided in this embodiment can be adjusted in various ways or a dedicated adapter frame can be added according to the size of the satellite, assembly requirements, etc.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
