Description

Technical Field

[0001] The invention relates to the technical field of rocket sled track installation, and in particular to a rocket sled track fastener adjustment device and method. Background Art

[0002] The rocket sled is a large-scale ground dynamic test system that uses rocket engines as power to propel a rocket sled forward at high speed on a dedicated track to obtain test data. The slides of the rocket sled are of two types: single-track and double-track. The rocket sled slide is a high-precision large-scale ground dynamic simulation test equipment. Together with the slide and test equipment, it can complete the rocket sled test. The rocket engine pushes the slide carrying the test piece along the slide, so that the slide and the test piece reach the speed required by the test, thereby quantitatively measuring and qualitatively analyzing the test piece under simulated environmental conditions. During the ground dynamic test, the requirements for the slide are very high, requiring a stable slide foundation, a high straightness alignment reference line (that is, the slide has high linear accuracy) and a smooth and seamless steel rail.

[0003] In recent years, the precision requirements for rocket sled slides have continued to increase, especially when installing longer rocket sled slides. The installation accuracy requirements for the slides are particularly high, requiring the main rail relative to the reference line and the auxiliary rail relative to the main rail to have an allowable deviation in the horizontal and vertical directions within ±0.2mm. Generally, the steel rails are specially processed and connected into interval seamless lines by flash welding, and then adjusted through fastener constraints to control the deviations in the horizontal and vertical directions within ±0.2mm, so that the rocket sled slide experiment can run at high speed.

[0004] The rocket skid track fasteners in the prior art are split, and the height and lateral length cannot be adjusted at the same time, or each bolt is usually measured using a measuring instrument, the adjustment amount is calculated, and then the fastener is adjusted. Regardless of which adjustment method is used, the adjustment efficiency is low, time-consuming and labor-intensive, and the rocket skid track installation and construction cost is increased. Summary of the invention

[0005] To solve the above technical problems, the purpose of the present invention is to provide a rocket sled track fastener adjustment device and method, which is used for the coarse adjustment of the rocket sled track fastener, has high adjustment efficiency, saves time and labor, and reduces the installation and construction cost of the rocket sled track. Another purpose of the present invention is to provide a rocket sled track fastener adjustment method, which adopts the above rocket sled track fastener adjustment device and can also achieve the above technical effects.

[0042] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0043] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention.

[0044] Please Figures 1 to 7 As shown, the rocket sled track fastener adjustment device provided by the present invention comprises a fixed base 1, an elevation adjustment component 2 connected to the fixed base 1 through a first clamping seat 3, an elevation base 25 arranged between the elevation adjustment component 2 and the fixed base 1, a first locking member 4 for locking the elevation base 25, and a direction adjustment component 5 connected to the fixed base 1. The fixed base 1 comprises a body 11 connected to the first clamping seat 3, an end member 12 connected to the body 11, and the direction adjustment component 5 can rotate around the center line of the body 11 to adjust the horizontal direction of the rocket sled fastener. Compared with the prior art, the rocket sled track fastener adjustment device provided by the present invention fixes the elevation adjustment component 2 and the direction adjustment component 5 through the fixed base 1, so that the rocket sled track fastener will not jump during the adjustment process. On the other hand, the provision of the first locking member 4 prevents the elevation base 25 from falling downward due to gravity during the adjustment process, thereby ensuring the reliability of the height adjustment of the rocket sled track fastener. During specific adjustment, the bottom of the first holder 3 is made to coincide with a certain scale line on the body 11 (for convenient calculation of the adjustment amount), and then the first holder 3 is fixed, the adjustment amount is calculated, and then the elevation scale is adjusted, and then the height of the outer vertical bolt 6 to be adjusted is adjusted until the top surface of the rail support plate 8 contacts the zero scale line of the elevation scale, and the adjustment of the rocket sled track fasteners (vertical bolts 6, rail support plate 8) is completed, and then the adjustment of the rocket sled track fasteners in the lateral direction is completed through the direction adjustment assembly 5. Therefore, the rocket sled track fastener adjustment device provided by the present invention is used for the coarse adjustment of the rocket sled track fasteners, has high adjustment efficiency, saves time and effort, and reduces the installation and construction cost of the rocket sled track.

[0045] Among them, in the embodiment provided by the present invention, the elevation adjustment assembly 2 includes a connecting rod 21 slidably connected to the first clamping seat 3, and a second locking member 22 for fixing the first clamping seat 3. The structure of the first clamping seat 3, the connecting rod 21 and the second locking member 22 is to be able to adjust the fixed base 1 and the elevation base 25, and can adapt to the adjustment of the rocket sled track fasteners under different circumstances.

[0046] Preferably, the elevation adjustment assembly 2 includes a level bubble gauge 23 disposed at the other end of the connecting rod 21. When the top surface of the rail support plate 8 contacts the zero scale line of the elevation base, the height of the connecting rod 21 is adjusted to allow the level bubble gauge 23 to be placed flat on the top surface of the rail support plate 8, and then the height of the inner vertical bolt 6 is adjusted until the bubble of the level bubble gauge 23 is centered. Therefore, the heights of the outer vertical bolts 6 and the inner vertical bolts 6 can also be adjusted individually using the elevation ruler 25. The operation method provided in this embodiment can also be used. First, the height of the outer vertical bolts 6 is adjusted using the elevation ruler 25, and then the level bubble meter 23 is used to make sure that the rail pad 8 through which the outer vertical bolts 6 and the inner vertical bolts 6 pass at the same time is horizontal, so as to indirectly make the heights of the outer vertical bolts 6 and the inner vertical bolts 6 the same. This adjustment method and structure will make the rail pad 8 on a horizontal plane with high flatness accuracy. In this way, the slide rail placed on the rail pad 8 is always in a horizontal state, so that the installation accuracy of the rocket sled slide rail is high and the rocket sled test can run at high speed.

[0047] The direction adjustment assembly 5 is located between the main body 11 and the first holder 3 to improve the structural rigidity and stability of the rocket sled track fastener adjustment device.

[0048] Specifically, the direction adjustment assembly 5 includes a second clamping seat 51, a third locking member 52 for locking the second clamping seat 51 to rotate and move up and down, and a direction base 53 connected to the second clamping seat 51. The transverse bolt 7 passes through the outer U-shaped baffle 9 and the inner U-shaped baffle 9 respectively. In order to make the outer U-shaped baffle 9 and the inner U-shaped baffle 9 offset from the center position, the second clamping seat 51 is first adjusted. In order to adjust the height of the direction base 53 in the vertical direction, the direction base 53 is at a suitable height, and the direction base 53 is parallel to the transverse bolt 7. According to the design offset requirement of the outer U-shaped baffle 9, it is adjusted to the corresponding scale, and then the inner U-shaped baffle 9 is installed. After the rail is laid, the bolts are tightened.

[0049] Among them, a fourth locking piece 54 is provided at one end of the second clamping seat 51 close to the direction base ruler 53, and the fourth locking piece 54 is used to lock the direction base ruler 53. The setting of the fourth locking piece 54 prevents the direction base ruler 53 from falling from the second clamping seat 51. On the other hand, in order to ensure the stability of the direction base ruler 53 during the installation of the outer U-shaped baffle 9 and the inner U-shaped baffle 9, the adjustment error is reduced.

[0050] Preferably, the provision of the spring 24 can reduce the impact of external factors on the level bubble meter 23, avoid damage to the level bubble meter 23, and at the same time ensure that when the level of the rail support plate is adjusted, the level bubble can sensitively respond to the adjustment situation.

[0051] The present application provides a method for adjusting a rocket skid rail fastener, which is applied to the above-mentioned rocket skid rail fastener adjustment device, and includes the following steps: S01: measuring the elevation and center offset of the outer vertical bolt 6, and calculating the design elevation of the rail support plate 8 and the adjustment amount of the offset of the outer U-shaped baffle 9; S02: making the end component 12 contact with the top surface of the vertical bolt 6; S03: fixing the first clamping seat 3, adjusting the elevation base scale, and adjusting the height of the vertical bolt 6 until the top surface of the rail support plate 8 is flush with the bottom of the elevation base scale; S04: adjusting the connection Adjust the height of rod 21, so that the horizontal bubble meter 23 is placed on the top surface of the rail pad 8, and adjust the vertical bolt 6 until the bubble of the horizontal bubble meter 23 is centered; S05: adjust the second clamping seat 51 to a suitable height, so that the direction base ruler 53 is parallel to the horizontal bolt 7, adjust the direction base ruler 53 to the corresponding scale according to the offset of the outer U-shaped baffle 9, adjust the outer U-shaped baffle 9, and then install the inner U-shaped baffle 9; S06: After the outer U-shaped baffle 9 and the inner U-shaped baffle 9 are installed, return to step S01. Among them, the beneficial effects of each step can be referred to the discussion of the rocket skid track fastener adjustment device, which will not be repeated here.

[0052] Therefore, the rocket sled rail fastener adjustment device and method provided in the present application can realize the coarse adjustment of the rocket sled rail fasteners, and the rocket sled rail fasteners mainly involve vertical bolts 6, transverse bolts 7 and rail support pads 8, through which the rocket sled slide rail is fixed.
