Description

Technical Field

[0001] This utility model belongs to the field of launch vehicle technology, and in particular relates to an auxiliary device for detaching cables from launch vehicles. Background Technology

[0002] During launch tests at the launch site, the detached cable transmits critical signals to the rocket. Currently used detached cables are thick in diameter and have high rigidity, making them difficult to bend and increasing the difficulty of operation. During the test, part of the cable will be suspended in the air for a long time, generating drag force at the detached connection, which threatens the safety of signal transmission.

[0003] In response to this situation, most domestic launch sites currently achieve a certain degree of support by fixing the launch pad to the launch pad or using steel plate supports.

[0004] However, the steel plate bracket has sharp edges, and when it comes into direct contact with the pulled-out cable, the cable's large diameter and weight pose a risk of cutting the internal cable structure, reducing its lifespan and threatening the security of signal transmission. Therefore, the existing technology of using a steel plate bracket to directly support the pulled-out cable is not feasible. At the same time, due to limitations such as the height of the pulled-out cable, there will be a certain angle between the pulled-out cable and the support mechanism. The planar support mechanism has a small contact area and poor support effect, which is also not feasible.

[0005] Therefore, it is necessary to design a dedicated auxiliary device for the launch vehicle's detachment cable to support and protect the detached cable while ensuring the integrity of the test signal. Utility Model Content

[0006] To address the issue of how to support and protect detached cables while ensuring the integrity of test signals, this invention proposes an auxiliary device for detached cables of launch vehicles. This device is designed based on the routing of the detached cables at a space launch site, combined with dimensional parameters such as the launch pad height. Experimental verification has shown that it can reduce the impact of suspended detached cables on the detachment connection and eliminate the safety hazard of long-term suspension of detached cables affecting test signals at the launch site.

[0007] To achieve the above objectives, this utility model is specifically implemented through the following technical solution:

[0008] This utility model provides a launch vehicle cable release auxiliary device, which is welded together from multiple L-shaped cross-section angle profiles extending axially; it includes: a base, a transverse extension mechanism, a longitudinal extension mechanism, a horizontal extension mechanism, and a support mechanism;

[0009] A horizontally placed C-shaped three-sided structure is formed by three upward-facing corner profiles, serving as a base;

[0010] A downward-facing corner profile serves as the lateral extension mechanism;

[0011] Using mirror-symmetric angle profiles spaced at preset intervals as the longitudinal extension mechanism, the bottom of the transverse extension mechanism is welded and fixed to the upper surface of the base through both ends of the longitudinal extension mechanism.

[0012] The horizontal extension mechanism is composed of two upward-opening angle profiles forming an L-shape. The main long side of the horizontal extension mechanism is connected and fixed to the transverse extension mechanism after adjusting the position through limiting holes at a preset distance. The short side on one side of the main long side extends horizontally and integrates a support mechanism for placing the launch vehicle's release cable on the upper surface. The short side is parallel to the symmetrical side in the base's C-shaped three-sided structure, and the free ends are in the same direction. The vertically upward side of the main long side is parallel to the vertically downward side in the transverse extension mechanism and the asymmetrical side of the base, and they are all in the same plane.

[0013] The support mechanism is a rectangular structure with a concave top edge, convex sides, and rounded corners. The launch vehicle's detachment cable is placed on the concave top edge.

[0014] Furthermore, the symmetrical sides of the base have a predetermined number and spacing of screw holes for fixing the base to the target position through the screw holes.

[0015] Furthermore, the longitudinal extension mechanism consists of a vertical extension mechanism and an inclined extension mechanism;

[0016] The two ends of the vertical extension mechanism are perpendicular to the base and the lateral extension mechanism, respectively, and are composed of a pair of mirror-symmetrical angle profiles with inward openings;

[0017] The inclined extension mechanism is on the same plane as the vertical extension mechanism and is located outside the vertical extension mechanism. It forms a bottom connection with the vertical extension mechanism and has a triangular structure with a preset included angle at the top, which is composed of a pair of mirror-symmetric angle profiles with inward openings.

[0018] Furthermore, the bottom end of the angle profile of the vertical extension mechanism is vertically welded and fixed to the inside of the right-angle side of the base. One side of the bottom end is close to the vertically upward side of the asymmetrical side of the base, and the other side is close to the vertically upward side of the symmetrical side of the base, and then welded and fixed to the base.

[0019] One end of the top is attached to the vertically downward edge of the horizontal extension mechanism, and the other end is attached to the bottom of the horizontal extension mechanism before being welded and fixed to the horizontal extension mechanism.

[0020] Furthermore, the bottom end of the angle profile of the inclined extension mechanism is welded and fixed to the outside of the right-angle side of the base and has a preset included angle. One side of the bottom end is close to the vertically upward side of the asymmetrical side of the base. After fixing the preset included angle, it is welded and fixed to the base.

[0021] The top is welded and fixed to the horizontal extension mechanism after one side is close to the vertical downward edge of the horizontal extension mechanism and the other side is close to the bottom of the horizontal extension mechanism, based on a preset angle.

[0022] Furthermore, the end of the lateral extension mechanism away from the support mechanism has a vertically downward rectangular blocking end, which is connected to the L-shaped free end of the downward-opening corner profile in the lateral extension mechanism; the blocking end is welded and fixed after abutting against the top of the corner profile corresponding to the inclined extension mechanism.

[0023] Furthermore, the short side length of the horizontal extension mechanism is less than the base plate length of the support mechanism. After the base plate of the support mechanism is connected to the upper surface of the short side of the horizontal extension mechanism, the base plate of the support mechanism is partially exposed.

[0024] Furthermore, the support mechanism consists of a top plate, side plates, a bottom plate, and vertical plates;

[0025] The side panels are two mirror-symmetrical convex plates with a smooth transition from top to bottom. The two ends of the side panels are connected to the ends of the top and bottom plates, respectively, forming a rectangular frame.

[0026] The top plate is parallel to the bottom plate, and the length of the top plate is less than that of the bottom plate. The top plate is recessed in the middle, and the bottom plate is a rectangular frame supported internally by vertical panels.

[0027] Furthermore, the bottom of the upright plate is vertically connected to the base plate.

[0028] Preferably, the number of the uprights is at least three, located at the central recess of the top plate and arranged at equal intervals towards both ends with the central recess of the top plate as the center.

[0029] The beneficial effects of this utility model are:

[0030] 1. This utility model comprehensively analyzes the usage environment and overall direction of the detachable cable, and designs an auxiliary device for detaching the launch vehicle cable by combining the dimensional parameters such as the height of the launch pad.

It has a simple structure, is convenient and reliable, is suitable for the special environment of the launch pad, has a large space for size adjustment, can be promoted to be used in various types of rockets, is easy to use, has low cost, and has good application prospects.

[0031] 2. The C-shaped three-sided structure of the base is stable and highly adaptable to the special environment of the launch pad. It is fixed to the target position through a structure with a preset number and spacing of screw holes. The bottom of the base is adjustable, which facilitates movement and fixation.

[0032] 3. Due to the height of the longitudinal extension mechanism fixing device, there is no angle between the launch vehicle's pull-out cable and the support mechanism;

[0033] 4. The mirror-symmetric triangular structure of the longitudinal extension mechanism increases the force support and further increases the overall stability of the entire device;

[0034] 5. The horizontal extension mechanism is combined with the transverse extension mechanism to adjust the position of the support mechanism. After the position of the support mechanism is adjusted, it can effectively support the launch vehicle release cable in various scenarios, which solves the problem of the gravity of the launch vehicle release cable being suspended in the air affecting the release connection and thus affecting the signal transmission, and ensures the safety of the transmitted signal.

[0035] 6. The support mechanism is a rectangular structure with a concave top edge, convex sides, and rounded corners. The launch vehicle's detachment cable is placed on the concave top edge, avoiding the risk of cutting the internal cable structure and preventing damage to the test cable. At the same time, it meets the requirements of smooth and error-free test signals at the launch site, ensuring stable signal transmission. Attached Figure Description
