Description

Technical Field

[0001] The present application relates to the technical field of rocket erection, and in particular to a switch mechanism for a rocket erection into position. Background Art

[0002] When launching a rocket, it is necessary to control the vertical angle of the rocket body. Due to the complex environment of the launch site, the current method of using photoelectric sensors for positioning cannot guarantee the reliability of the rocket's vertical position. Generally, a travel switch is used to control the vertical position.

[0003] like Figure 1 The figure shows a schematic diagram of the structure of an existing rocket erection device. The existing rocket erection device is composed of a trigger block, a travel switch and an adjustment device 14, which is used to control the position of the rocket erection. The trigger block is fixedly connected to the erection structure, and rotates around the central axis to the erection position under the action of the hydraulic cylinder. Before the rocket is erected, the erection structure is in the initial position 10 of the erection structure, and the trigger block connected to the erection structure is in the initial position 12 of the trigger block. From the initial position, the trigger block rotates a corresponding angle (generally 90°) to trigger the travel switch, the erection structure is in the final position 11 of the erection structure, and the trigger block is in the final position 13 of the trigger block. When debugging the equipment, adjust the travel switch adjustment device according to the required erection position of the rocket to ensure that the travel switch gives an erection position signal every time the rocket is erected to this position, and the rocket erection action stops according to the erection position signal given by the travel switch.

[0004] Since the travel switch has a trigger stroke and a positive trigger stroke, it may not give a trigger signal when it starts to trigger. Only when it reaches the positive trigger stroke can it give a trigger signal. In this way, the starting trigger stroke to the positive trigger stroke, converted into an angle according to the installation position, is the erection accuracy of this type of solution.

[0005] For launch systems that use an erector to erect rockets, due to structural limitations, it is impossible to improve the erection accuracy by increasing the distance from the trigger position to the rotation center.

[0006] Therefore, there is an urgent need to provide a mechanism that can conveniently adjust the rocket's vertical angle, ensure the accuracy of the rocket's vertical angle, and improve the accuracy of the rocket's vertical position. Summary of the invention

The travel switch adjustment plate 571 is fixedly connected to the mounting seat assembly 51 through screws and a vertically arranged oblong hole 575, and the travel switch mounting plate 572 is fixedly connected to the travel switch adjustment plate 571 through screws and a horizontally arranged oblong hole 575. By adjusting the position of the screw in the vertically arranged oblong hole 575 and the position of the screw in the horizontally arranged oblong hole 575, the travel switch 573 can be adjusted in the horizontal and vertical directions. The travel switch adjustment mechanism 57 is used to adjust the initial trigger position of the travel switch 573.

[0084] like Fig.14 As shown, the first-stage active tooth 523 rotates in the direction indicated by the arrow, driving the first-stage connecting rod 524 to swing, the swing of the first-stage connecting rod 524 drives the second-stage connecting rod 531 to swing, the swing of the second-stage connecting rod 531 drives the third-stage connecting rod 542 to swing, the swing of the third-stage connecting rod 542 drives the connecting rod mechanism 551 to swing, and the positions of the third-stage connecting rod 542 and the connecting rod mechanism 551 after the swing are shown in FIG. Fig.14 The third-stage connecting rod 5411 after the middle swing and the connecting rod mechanism 5511 after the swing.

[0085] As a specific embodiment of the present invention, for the rotation distance of the meshing points of the connecting rod teeth at each level, the magnification of the first-level connecting rod 524 teeth is 4, the magnification of the second-level connecting rod 531 is 5, and the magnification of the third-level connecting rod 542 is 5. Then, the magnification of the end stroke of the third-level connecting rod 542 and the first-level connecting rod 524 is 4*5*5=100.

[0086] As a specific embodiment of the present invention, the inclination angle of the travel switch trigger slope 556 is 15 degrees. According to the vertical direction of the travel switch 573, the positive disconnection travel of 6.4 (the inherent parameter of the travel switch 573), the horizontal travel of the trigger block 554 is 6.4 / tan15°=23.9mm. Fig.14 A=30, then 5A=150, and the swing angle of the third-stage connecting rod 542 can be calculated to be 9.2°, and the swing angle of the first-stage active tooth 523 is 0.092°. The pitch circle radius of the trigger tooth 44 on the erection frame 1 is 270, so the rotation angle of the erection frame 1 is 0.092° / 9 (the magnified ratio of the trigger tooth 44 on the erection frame 1 and the first-stage active tooth 523)=0.01°. It can be seen that the accuracy of this mechanism is 0.01°.

[0087] The beneficial effects achieved by this application are as follows:

[0088] (1) The angle adjustment mechanism provided at the trigger mechanism of the present application uses the angle adjustment mechanism to adjust the trigger tooth to the corresponding angle position of the erection frame according to the required erection angle of the rocket, and the installation position of the trigger tooth is determined by the scale on the ruler. When the trigger tooth is at the required erection angle position, after the erection frame is erected around the rotation axis, the trigger tooth rotates with the erection frame around the rotation axis, and after the trigger tooth rotates, it triggers the travel switch. After the travel switch is triggered, the erection stops, thereby achieving accurate adjustment of the rocket erection angle, and conveniently adjusting the rocket erection angle.

[0089] (2) The present application is provided with a stroke amplification mechanism, which adopts a three-stage connecting rod structure. The three-stage connecting rod structure realizes the amplification of the connecting rod swing angle through tooth engagement. The stroke amplification mechanism is connected to the horizontal trigger mechanism. The horizontal trigger mechanism converts the angle amplified by the stroke amplification mechanism into a horizontal movement distance. A stroke switch is installed at the end of the horizontal trigger mechanism. The horizontal trigger mechanism triggers the stroke switch. The stroke amplification mechanism realizes angle amplification through tooth engagement, thereby improving the accuracy of the equipment and further improving the accuracy of the rocket erection.

[0090] (3) The clutch mechanism of the first-stage connecting rod of the present application is realized by the cooperation and connection between the plunger (containing a spring and a steel ball) and the V-groove on the first-stage bearing seat. At the same time, the clutch mechanism is connected with a tension spring, and the tension spring pulls the plunger to rotate relative to the first-stage bearing seat to achieve automatic return. It can provide signals at multiple positions during the rocket erection process, thereby increasing the process control accuracy of the rocket erection.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
