Technical Field

[0001] This utility model belongs to the field of aerospace space scene simulation equipment technology, specifically relating to a plate frame horizontal moving caster structure for a space simulation demonstration device. Background Technology

[0002] Space scene simulation demonstration technology is still in its infancy. When designing and manufacturing space simulation demonstration platform devices, the lateral movement of the suspended, vertically upright, arc-shaped space frame and the structural problems under complex conditions are among the current difficulties. There are no mature technologies and experiences to draw on, and existing casters cannot meet its requirements in terms of functional requirements, connection structure, stability, and appearance.

[0003] Therefore, the problem that this utility model needs to solve is that the casters of the space panel frame must not only have a reasonable structure for reliable connection with the thin space panel frame, but also consider the mutual connection with the T-shaped structure on the outside of the panel frame, and also solve the problem that the vertical panel frame can stand upright on its own, and further ensure that the vertical space panel frame can rotate 360° around the suspension axis above the space panel frame. Utility Model Content

[0004] To address the complex structural challenge of lateral movement of a vertical spatial frame in a three-dimensional simulation device controlled by a spatial track, this invention provides a caster structure for lateral movement of the frame in a spatial simulation demonstration device. This structure supports the spatial frame in the device, allowing it to stand upright on the platform and rotate along a circular track. It also ensures that the frame can rotate 360° around the suspension axis above it.

[0005] To achieve the above objectives, the present invention adopts the following specific technical solution: A lateral movement caster structure for a space simulation demonstration device's frame includes a caster support frame, two casters, and a clamp-type connecting frame; wherein: The wheel support frame has an "h" shaped structure and an arc-shaped cavity at the bottom for mounting the wheels; The traveling wheel adopts a transverse double traveling wheel structure with an arc trajectory and is rotatably mounted in the arc cavity of the traveling wheel support; the outer circumference of the traveling wheel is provided with a U-shaped groove that mates with the annular track, and the rotation axis of the traveling wheel points to the center of the annular track; The clamp-type connecting frame is arranged radially along the annular track, and its outer end is fixedly connected to the wheel support frame; the clamp-type connecting frame is provided with slots and multiple fixing bolt holes, and the width of the slots matches the thickness of the space plate frame.

[0006] Furthermore, the wheel support frame includes an outer vertical plate, an inner vertical plate, and a horizontal plate fixedly connected between the outer vertical plate and the inner vertical plate; the arc-shaped cavity is formed between the outer vertical plate, the inner vertical plate, and the horizontal plate; along the radial direction of the annular track, the outer vertical plate is located on the side of the inner vertical plate away from the center of the annular track; the wheel is mounted between the outer vertical plate and the inner vertical plate via a rotating shaft.

[0007] Furthermore, both the outer and inner uprights are arc-shaped plates; the radius of the annular track is between the radius of the outer upright and the radius of the inner upright.

[0008] Furthermore, the portion of the outer vertical plate located above the horizontal plate forms a trapezoidal plate that is wider at the bottom and narrower at the top, and the width of the top end is consistent with the width of the outer side of the T-shaped plate on the outer side of the space frame.

[0009] Furthermore, the outer end face of the clamp-type connecting frame is fixedly connected to the inner side of the outer vertical plate, and the bottom end face is fixedly connected to the top surface of the horizontal plate.

[0011] Furthermore, the height of the flat plate is greater than the height of the trapezoidal plate, and a 45° chamfer is provided at the outer end of the portion that extends above the trapezoidal plate.

The horizontal moving caster structure of the plate frame of this utility model is used in a space simulation demonstration device. It adopts a horizontal double-wheel structure with an arc trajectory, which not only makes it easy for the space plate frame to run smoothly on the circular track, but also solves the problem of the vertical space plate frame standing upright on its own.

[0013] 2. The horizontal moving caster structure of this utility model adopts an "h"-shaped caster support frame and sets the outer side plate of the upper part of the horizontal plate into a trapezoidal shape, which solves the problem of perfect connection with the outer T-shaped plate of the space frame, meets the visual requirements, and provides a space for setting up the clamp-type connecting frame and a reliable fixed plate surface. At the same time, it greatly improves the rationality and stability of the structure.

[0019] This utility model embodiment provides a horizontally movable caster structure 1 for a space simulation demonstration device, which can be used for... Figure 5The three-dimensional simulation platform supporting space-ground coordinated orbit control includes a platform frame 2 and a space plate frame 3. A tabletop is provided on the top of the platform frame 2, and multiple concentric annular tracks 4 are provided on the tabletop. Both ends of the space plate frame 3 are supported on the tabletop by a lateral movement caster structure 1 of this invention, and can rotate along the annular tracks 4. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the structure, the transverse moving caster structure 1 of the plate frame includes a caster support frame 11, two casters 12, and a clamp-type connecting frame 13; wherein: The wheel support frame 11 has an "h"-shaped structure with an arc-shaped cavity at the bottom for mounting the wheel 12. The wheel support frame 11 serves as an intermediate component, assembling the wheel 12 and the clamp-type connecting frame 13 together. The wheel support frame 11 and the clamp-type connecting frame 13 together support the space plate frame 3 and move along the circular track 4 via the wheel 12 at the bottom, thereby driving the space plate frame 3 to move along the circular track 4.

[0020] The traveling wheels 12 adopt a transverse double-wheel structure with an arc-shaped trajectory and are rotatably mounted in the arc-shaped cavity of the traveling wheel support 11. The two traveling wheels 12 are located at the front and rear ends of the traveling wheel support 11, respectively, realizing two-point support at one end of the spatial plate frame 3, improving the stability and reliability of the support. The outer circumference of the traveling wheels 12 is provided with a U-shaped groove 121 that mates with the annular track 4. The U-shaped groove 121 and the annular track 4 with the raised platform achieve a concave-convex fit, so that the traveling wheels 12 always move along the annular track 4 and prevent the traveling wheels 12 from leaving the annular track 4. The traveling wheels 12 are mounted on the traveling wheel support 11 via a rotating shaft 14, and the rotation axis of the traveling wheels 12 points to the center of the annular track 4. The traveling wheels 12 can be nylon wheels with bearings and U-shaped grooves 121, which can be machined in-house or purchased directly.

[0021] The clamp-type connecting frame 13 is arranged radially along the annular track 4, and its outer end is fixedly connected to the wheel support frame 11. The clamp-type connecting frame 13 is provided with slots 131 and multiple fixing bolt holes 132. The width of the slots 131 matches the thickness of the space plate frame 3. The end of the space plate frame 3 is inserted into the slots 131 of the clamp-type connecting frame 13, and the space plate frame 3 is fixedly connected to the clamp-type connecting frame 13 by bolts passing through the fixing bolt holes 132, thereby supporting the end of the space plate frame 3.

[0022] In the above-mentioned lateral movement caster structure 1 of the plate frame, as follows: Figure 1 and Figure 2As shown, the wheel support frame 11 includes an outer vertical plate 111, an inner vertical plate 112, and a horizontal plate 113, with the horizontal plate 113 fixedly connected between the outer vertical plate 111 and the inner vertical plate 112; an arc-shaped cavity is formed between the outer vertical plate 111, the inner vertical plate 112, and the horizontal plate 113. Along the radial direction of the annular track 4, the outer vertical plate 111 is located on the side of the inner vertical plate 112 away from the center of the annular track 4; the wheel 12 is mounted between the outer vertical plate 111 and the inner vertical plate 112 via a rotating shaft 14. Both the outer vertical plate 111 and the inner vertical plate 112 are arc-shaped plates; the radius of the annular track 4 is between the radius of the outer vertical plate 111 and the radius of the inner vertical plate 112, with the radius of the outer vertical plate 111 being larger than the radius of the inner vertical plate 112. The portion of the outer vertical plate 111 located above the horizontal plate 113 forms a trapezoidal plate that is wider at the bottom and narrower at the top, and the width of its top end is consistent with the width of the outer side of the outer T-shaped plate of the space frame 3. The top end of the outer vertical plate 111 is used to support the outer side of the outer T-shaped plate of the space frame 3.

[0023] like Figure 2 As shown, the outer end face of the clamp-type connecting frame 13 is fixedly connected to the inner side of the outer vertical plate 111, and the bottom end face is fixedly connected to the top surface of the horizontal plate 113. Figure 4 As shown, the clamp-type connecting frame 13 consists of two parallel flat plates; a slot 131 is formed between the two flat plates for inserting the end of the spatial plate frame 3. A clearance fit can be used between the slot 131 and the end of the spatial plate frame 3 to facilitate insertion of the spatial plate frame 3 into the slot 131; fixing bolt holes 132 penetrate the thickness of both flat plates for inserting bolts. The height of the flat plate is greater than the height of the trapezoidal plate, and a 45° chamfer is provided at the outer end of the portion extending above the trapezoidal plate. Increasing the area of ​​the flat plate improves the contact area and connection reliability between the clamp-type connecting frame 13 and the spatial plate frame 3.

[0024] In the aforementioned transverse movable caster structure 1, both the caster support frame 11 and the clamp-type connecting frame 13 can be made of 2mm thick steel plate (stainless steel plate). During fabrication, the caster support frame 11 is fabricated first, then the clamp-type connecting frame 13 is welded onto the caster support frame 11, and finally the two casters 12 are installed to complete the fabrication. It should be noted that the centerlines of the two casters 12 are not parallel. The horizontal angle between the centerlines of the two casters 12 must be determined based on the curvature of the circular track 4 used. Simultaneously, the vertical plates on both sides of the caster support frame 11 are also curved, and their horizontal curvature should match that of the track.

[0025] The aforementioned transverse moving caster structure 1 for the spatial simulation demonstration device employs a transverse double-wheel structure with an arc-shaped trajectory. This not only facilitates the smooth movement of the spatial panel 3 on the circular track 4 but also solves the problem of the vertical spatial panel 3 maintaining its own upright position. The transverse moving caster structure 1 utilizes an "h"-shaped wheel support frame 11 and sets the outer vertical plate 111 of the upper part of the horizontal plate 113 in a trapezoidal shape, solving the problem of perfect connection with the outer T-shaped plate of the spatial panel 3, meeting aesthetic requirements, and providing space and a reliable fixed surface for the clamp-type connecting frame 13. This also significantly improves the rationality and stability of the structure. The clamp-type connecting frame 13 in the transverse moving caster structure 1 simplifies the connection between the casters and the spatial panel 3 and ensures a firm and reliable connection.

[0026] The aforementioned transverse moving caster structure 1 is used on the space frame 3 of the "3D simulation platform supporting space-ground collaborative orbit control". The connection process with the space frame 3 is as follows: insert the space frame 3 directly into the slot 131 of the clamp-type connecting frame 13, align the outer vertical plate 111 of the wheel support frame 11 with the outer edge of the outer T-shaped plate of the space frame 3, adjust its height and angle, and check whether the horizontal distance between the space frame and the upper suspension shaft is consistent with the radius of the track; finally, tighten the fixing bolts on the clamp-type connecting frame 13, ensuring that the position of the casters is accurate and the fixing is secure; after the caster connection is completed, the space frame 3 can be placed on the track of the demonstration platform for operation.

[0027] To ensure a smooth connection between the aforementioned transverse moving caster structure 1 and the outer T-shaped plate of the spatial frame 3, and to address both the installation of the clamp-type connecting frame 13 and its reliable connection with the spatial frame 3, the caster support frame 11 is changed from a traditional "n"-shaped structure to an "h"-shaped structure. Specifically, the outer vertical plate of the "n"-shaped caster support frame 11 is extended upwards, and the extended outer vertical plate is trapezoidal, with its upper width matching the width of the outer plate of the T-shaped structure of the spatial frame 3. To strengthen the connection with the spatial frame 3, a longitudinal clamp-type connecting frame 13 is installed on the transverse "h"-shaped caster support frame 11. To ensure both a smooth connection between the outer vertical plate 111 of the caster support frame 11 and the outer side of the spatial frame 3, and to maintain the height of the clamp-type connecting frame 13, a flat plate is installed higher than the outer vertical plate 111 of the caster support frame 11. The protruding portion is chamfered at a 45-degree angle, and fixing bolt holes 132 are provided on the flat plate.

Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
