Description

Technical Field

[0001] This invention belongs to the field of launch sector angle measurement technology, and more specifically, relates to a launch guide rail sector angle measurement device and method. Background Technology

[0002] Currently, missile development typically requires ground-based launch tests. During launch, launch parameters such as the launch sector angle and elevation angle need to be set. In existing technology, before launch, the coordinates of the launch point and target point are collected to determine the azimuth angle of the line connecting them. Then, a launch site is established, aligning the launch rail roughly with the target point. High-precision direction-finding equipment is used to measure the actual azimuth angle of the launch rail. Based on these two azimuth angle values, the missile launch sector angle can be calculated. However, this method of measuring the launch sector angle is cumbersome and time-consuming.

[0040] In this embodiment, a first reinforcing rib is provided between the upright plate and the bottom plate.

[0041] Optionally, one end of the cantilever 1 is connected to the upright plate via a first connecting plate 6 disposed on the outer periphery of the cantilever 1, and both the first connecting plate 6 and the upright plate are provided with first mounting holes.

[0042] Specifically, the first mounting hole is designed to facilitate the connection of the first connecting part 2 to one end of the cantilever 1 via a bolt fastening assembly.

[0043] Optionally, the outer periphery of the cantilever 1 is cylindrical.

[0044] Specifically, the cylindrical cantilever 1 allows the rotating connecting parts fitted around its outer periphery to rotate around its circumference, simplifying the structure.

[0045] Optionally, the rotating connecting component includes a sleeve portion 7 and a connecting portion 10 disposed on one side of the sleeve portion 7. The sleeve portion 7 is rotatably sleeved on the cantilever 1, and the connecting portion 10 is used to connect the rotary slide 4.

Both the third connecting plate and the rotary slide 4 are provided with second mounting holes.

[0052] Specifically, the second connecting plate is connected to the outside of the cantilever 1 via the third connecting plate, and the connection part 10 can be connected to the slide base of the rotary slide 4 via bolt assembly through the setting of the second mounting hole.

[0053] In this embodiment, a second reinforcing rib is provided between the second connecting plate and the third connecting plate.

[0054] Optionally, the rotary slide 4 is a micrometer rotary slide and can rotate 360° in the horizontal plane; a scope mounting base 11 is provided on the rotary slide 4, and the scope 5 is connected to the scope mounting base 11 through a piconet 12 and can be locked with screws.

The micrometer can achieve precise fine adjustment, which can improve the measurement accuracy of the device; the sight mounting base 11 is set on the rotating base of the rotary slide 4 and can rotate together with the rotating base.

[0056] In this embodiment, the rotating connecting component, the stop 8, and the locking component 9 are treated with black anodized surface treatment, which can prevent oxidation of the parts surface and increase the friction coefficient between the side of the rotating connecting component and the side of the stop 8, and between the side of the connecting part 10 and the side of the locking component 9, thereby improving the locking force of the rotating connecting component.

[0057] like Figure 2 and Figure 3 As shown, the present invention also provides a method for measuring the sector angle of a launch guide rail, which utilizes the aforementioned launch guide rail sector angle measuring device, comprising:

[0058] Adjust the angle scale of the rotary slide 4 to its zero position and lock it;

[0060] The elevation angle of the sight 5 is adjusted by rotating the connecting component, and the rotating connecting component is fixed to the cantilever 1 by the fixing component.

[0061] Rotate the aiming scope 5 by rotating the slide 4 so that the center of the crosshairs of the aiming scope 5 is aligned with the center of the target 13.

[0062] Read the rotation angle of the rotary slide 4 to obtain the launch sector angle of the launch rail 3.

[0063] Specifically, when measuring the launch rail sector angle using the aforementioned launch rail sector angle measuring device, before installing the launch rail sector angle measuring device, first observe whether the angle scale of the rotary slide 4 is at zero. If it is not at zero, adjust the angle of the rotary slide 4 to zero and lock it. After the launch rail 3 is roughly oriented towards the target 13 and fixed, install the base of the launch rail sector angle measuring device into the launch rail 3 and tighten it with the set screw to ensure a rigid connection between the base and the launch rail 3. Loosen the locking piece 9 and manually adjust the sleeve part 7 relative to the cantilever 1. Adjust the elevation angle of the sight 5. After visually observing that the elevation angle is suitable, tighten the locking part 9 to lock the sleeve part 7. Unlock the rotating slide 4 and adjust the micrometer knob of the rotating slide 4. The sight 5 will rotate horizontally with its rotating base so that the center of the crosshairs of the sight 5 is aligned with the center of the target 13. Then lock the rotating slide 4 and read the micrometer scale. Read the smallest division of the micrometer scale. According to the fact that one smallest division is equal to 0.92 minutes, the launch sector angle of the launch rail 3 can be calculated, which is the sector angle of missile launch. After the measurement is completed, loosen the fastening screws on the base and remove the launch rail sector angle measuring device. This launch rail sector angle measuring device and method has a simple structure, is easy to operate, and has high measurement efficiency. It can be quickly retracted after the measurement is completed, shortening the preparation time before missile launch. Moreover, the launch rail sector angle measuring device is a purely mechanical component with a simple structure, high reliability, and light weight, making it easy to carry. It has significant advantages in testing, transportation, and storage.
