Description

Technical Field

[0001] This utility model belongs to the field of rocket manufacturing auxiliary equipment technology, and more specifically, it relates to the star cover frame hoisting structure. Background Technology

[0002] Currently, the satellite fairing is an important component of the rocket body, and its fairing frame, as the core tooling for fairing manufacturing and assembly, has a typical circumferential arc structure, characterized by its large size, heavy weight, and precise structure. During the rocket manufacturing process, the fairing frame needs to undergo multiple transfers, hoisting, and positioning operations, placing extremely high demands on the adaptability, stability, and safety of the hoisting structure.

[0003] Existing hoisting equipment is mostly of a general-purpose structure, lacking a dedicated design for the circumferential arc structure of the star-shaped frame, resulting in numerous technical defects in practical applications. The base of the general-purpose hoisting structure is mostly flat or conventional irregularly shaped, which cannot fit tightly against the arc-shaped sidewalls of the star-shaped frame. During hoisting, contact gaps are prone to occur, leading to uneven stress. This not only affects the stability of hoisting but may also damage the precision structure of the frame surface due to excessive local pressure.

[0004] In terms of hoisting direction adjustment, traditional hoisting structures can only achieve vertical hoisting in a single direction, which cannot meet the horizontal hoisting requirements of the star-shaped frame during assembly. Additional auxiliary transfer equipment is required, which increases the complexity of the operation process and manufacturing costs. At the same time, multiple transfers can easily lead to frame positioning deviations, affecting the subsequent assembly accuracy.

[0005] Furthermore, existing hoisting structures mostly have fixed hoisting positions, making it impossible to flexibly adjust the hoisting points according to the specific structure and weight distribution of the star-shaped frame, resulting in extremely poor adaptability. Although some adjustable hoisting structures have adjustment functions, the adjustment methods are cumbersome and lack reliable buffering and stabilizing structures. During hoisting, vibration and swaying can easily cause the connection between the hoisting joint and the hoisting seat to loosen, and there is even a risk of the adapter breaking, seriously threatening operational safety and the integrity of the frame. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a star-shaped frame hoisting structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a star-shaped frame hoisting structure, including a star-shaped frame.

[0008] The support base is installed on one side of the star-shaped frame;

[0009] The base plate is welded to the bottom of the support base;

[0010] A mounting plate is welded to one side of the support base, and the mounting plate is provided with symmetrical adjustment threaded holes.

[0011] The lifting base is fixed to the mounting plate by bolts.

[0012] The positioning plate is welded to the bottom of the lifting base;

[0013] A positioning cover plate is welded to the top of the lifting base;

[0014] The buffer section is installed inside the lifting base;

[0015] The hoisting unit, bolted to one side of the positioning cover plate, includes:

[0016] The adapter plate has a positioning hole in the center;

[0017] The adapter is welded into the positioning hole.

[0018] In some embodiments, a slope is provided on one side of the support base, and the slope angle ranges from 23 to 33 degrees.

[0019] In some embodiments, the inclined angle of the support is set at 27 degrees.

[0020] In some embodiments, a reinforcing cavity is provided inside the support base.

[0021] Multiple reinforcing plates are installed inside the reinforcing cavity.

[0022] In some embodiments, multiple reinforcing ribs are welded to the angle between the lifting base and the positioning cover plate.

[0023] In some embodiments, the buffer includes positioning plates symmetrically installed within the cavity of the lifting base.

[0024] A buffer sleeve is engaged between the positioning plates. The buffer sleeve has multiple annular protrusions on its circumferential surface. The positioning plates have slots that engage with the multiple annular protrusions.

[0025] In some embodiments, the adapter is divided into a lifting section and a buffer section. The lifting section is provided with multiple cylindrical steps, and the buffer section is provided with a smooth column. The buffer section is interference-fitted with the buffer sleeve.

[0026] In some embodiments, at least two star-shaped frame hoisting structures are provided and are symmetrically arranged along the circumferential direction of the star-shaped frame.

[0027] This utility model provides a star-shaped frame hoisting structure, which has the following beneficial effects:

[0028] 1. By designing an arc-shaped base plate, its curvature is precisely matched with the side wall of the star-shaped frame, allowing it to fit tightly against the circumferential structure of the frame. Compared with general hoisting structures, this completely solves the problems of loose fit and uneven force distribution during hoisting of the star-shaped frame, making it uniquely specialized in the field of rocket manufacturing.

[0029] 2. The inclined lifting base design allows for free switching between vertical and horizontal lifting without the need for additional auxiliary transfer equipment, simplifying the lifting process, enhancing lifting flexibility, and improving the positioning accuracy during the assembly of the star-shaped frame. In addition, the mounting plate at the bottom of the lifting base is equipped with adjustment threaded holes, which can flexibly adjust the lifting position according to the weight distribution of the star-shaped frame and the lifting requirements.

[0030] 3. By designing a buffer sleeve and upper and lower locking positioning plates inside the lifting base, the vibration and impact of the lifting can be effectively absorbed. The nested connection structure combined with the limit design enhances the connection stability between the adapter and the lifting base, avoids the risk of adapter breakage, and ensures the safety and integrity of the star-shaped frame lifting process.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In one embodiment, see Figure 1-5 This utility model provides a technical solution: a star-shaped frame hoisting structure, including a star-shaped frame 1, a support base 3 installed on one side of the star-shaped frame 1, and an inclined surface on one side of the support base 3. The inclination angle of the inclined surface is in the range of 23 to 33 degrees. Currently, the inclination angle of the inclined surface of the support base 3 is set to 27 degrees, which is in line with the inclination angle range setting and facilitates installation. A reinforcement cavity is set inside the support base 3, and multiple reinforcement plates 301 are installed in the reinforcement cavity to ensure the overall stability of the support base 3. At least two star-shaped frame hoisting structures are provided and are symmetrically arranged along the circumference of the star-shaped frame 1 to improve the overall hoisting strength.

[0041] The base plate 2 is welded to the bottom of the support base 3. The bottom surface of the base plate 2 is an arc surface that fits against one side of the star-shaped frame 1. The base plate 2 is made of high-strength alloy material, and its arc curvature matches the side wall curvature of the star-shaped frame 1. It can fit tightly against the circumferential side wall of the star-shaped frame 1, increase the contact area, ensure uniform force during hoisting, and avoid local stress concentration that could damage the frame.

[0042] Mounting plate 4 is welded to one side of support base 3. The mounting plate 4 is provided with symmetrical adjustment threaded holes 401. The position and height can be adjusted according to the actual installation requirements to adapt to different weight distributions and hoisting requirements of star-shaped frame 1.

[0043] The lifting base 6 is fixed to the mounting plate 4 with bolts. The positioning plate 5 is welded to the bottom of the lifting base 6, the positioning cover plate 9 is welded to the top of the lifting base 6, multiple reinforcing ribs 601 are welded to the angle between the lifting base 6 and the positioning cover plate 9, and a buffer is installed inside the lifting base 6.

[0044] In one embodiment, see Figure 3 as well as Figure 5 The buffer section includes positioning plates 8, which are symmetrically installed in the inner cavity of the lifting base 6. The buffer sleeve 7 is engaged between the positioning plates 8. Multiple annular bosses are provided on the circumferential surface of the buffer sleeve 7. The positioning plates 8 are provided with slots, which engage with the multiple annular bosses to form a nested connection structure, providing a continuous and stable buffer pressure reduction space.

[0045] In one embodiment, see Figure 1 , Figure 3 as well as Figure 5 The hoisting part is bolted to one side of the positioning cover plate 9 and includes an adapter plate 10 with a positioning hole in the center. The adapter 11 is welded into the positioning hole to ensure integrity. The adapter 11 is divided into a hoisting section 111 and a buffer section 112. The hoisting section 111 is provided with multiple columnar steps, and the buffer section 112 is provided with a smooth column. The buffer section 112 is interference-fitted with the buffer sleeve 7 to avoid loosening of the connection, further increase the torque, improve the hoisting strength, and thus effectively prevent the adapter 11 from breaking.

[0046] The specific usage and function of this embodiment: When in use, according to the side wall curvature of the star-shaped frame 1 and the hoisting requirements, align the arc-shaped fitting face of the base plate 2 with the circumferential side wall of the star-shaped frame 1 to ensure close contact with the side wall of the frame. Secure the base plate 2 and the support seat 3 to the frame with bolts to complete the installation and positioning.

[0047] According to the hoisting direction requirements, the vertical hoisting or horizontal hoisting mode is selected using the inclined hoisting base 6. The adapter 11 on the hoisting part is connected to the hoisting base 6. If the hoisting position needs to be adjusted, according to the weight distribution and assembly requirements of the star-shaped frame 1, the appropriate position of the adjustment threaded hole 401 on the bottom mounting plate 4 of the hoisting base 6 is selected. The bolt is fitted into the adjustment threaded hole 401 to position the adapter 11 and achieve precise adjustment of the hoisting position.

[0048] At this time, the buffer section 112 of the adapter 11 is tightly fitted into the buffer sleeve 7 inside the lifting base 6. The multiple annular bosses of the buffer sleeve 7 are engaged by the slot of the positioning plate 8 to achieve positioning. Through the cooperation between the slot and the annular bosses, a certain buffer engagement is formed. The external lifting equipment is started, and the vibration and impact generated during the lifting process are continuously absorbed. The increased torque of the buffer section 112 greatly improves the lifting strength and avoids the adapter 11 from shaking or breaking, thus achieving safe and stable lifting of the star-shaped frame 1.

[0049] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
