Description

Technical Field

[0001] This utility model relates to the field of rocket energy refueling technology, specifically a tool for assembling and disassembling rocket gas-liquid connectors. Background Technology

[0002] Before fueling a rocket, gas supply lines need to be connected so that the ground-based gas supply system can supply gas to relevant onboard devices. To reduce the number of interfaces between the rocket and the ground-based gas supply system, multiple gas supply lines are typically combined into a single gas connector, allowing for seamless connection and detachment between the multiple gas supply lines and the rocket. This reduces the risk of gas line detachment and increases the reliability of the gas supply process.

[0003] In response to this, utility model patent CN211417651U discloses a tooling structure for assembling and disassembling rocket gas-liquid connectors. This tooling structure includes: a boss, a pry bar and a fixing rod spaced apart along the height direction of the boss, and a connector connecting the pry bar and the boss. The boss includes a base and a column. The fixing rod is movably connected to the column along its axial direction to adjust the distance between the fixing rod and the pry bar along the column's axial direction. The pry bar is rotatably connected to the base via the connector. The pry bar also has a through hole at the connection point with the connector, allowing for adjustment of the pry bar's position along its length as needed during installation. This tooling structure is adjustable both along the column's axial direction and the pry bar's length, accommodating connectors of different sizes and making connector assembly and disassembly operations more convenient and labor-saving for workers.

[0004] However, the assembly and disassembly tools in the aforementioned patent applications still have some problems: the current assembly and disassembly tools require repeated calibration of the fixed position during use, and this process requires frequent adjustment of the tools, which makes it inconvenient for personnel to operate. In addition, the shapes of different specifications of gas-liquid connectors are different, and personnel cannot replace the assembly and disassembly parts of the device tools according to the corresponding gas-liquid connectors, which reduces their scope of use.

Moving blocks 404 are threaded onto both sides of the outer wall of the bidirectional lead screw 402. A T-shaped docking groove 405 is formed at one end of each moving block 404. A T-shaped docking block 406 is disposed within the T-shaped docking groove 405. A docking arm 407 is fixedly attached to one end of the T-shaped docking block 406.

A locking groove matching the locking element 410 is formed at the top of the T-shaped docking block 406. The top of the locking element 410... A movable column 408 is hinged to the T-shaped docking block 406. The outer wall of the movable column 408 is inserted and connected to the movable hole at the top of the T-shaped docking block 406. A pull ring is fixedly provided at the top of the movable column 408. A retaining ring 411 is fixedly provided at the bottom of the outer wall of the movable column 408. A connecting spring 412 is fixedly provided between the retaining ring 411 and the movable groove 409. The connecting spring 412 is sleeved on the outside of the movable column 408. The calibration mechanism 5 includes a fixed plate 501. A mounting base 502 is fixedly provided on one side of the fixed plate 501. A line laser light 503 is provided in the mounting base 502. The light of the line laser light 503 is located at the center of the two docking arms 407.

[0028] A second stepper motor 7 is installed at the top of the drive frame 1. The output end of the second stepper motor 7 is fixedly connected to the top of the drive screw 2. A handle 6 is fixedly installed on the other side of the drive frame 1. A strip-shaped elongated hole is opened on the surface of the other side of the drive frame 1. The inner wall of the strip-shaped elongated hole is inserted and connected to the outer wall of the drive block 3. A first stepper motor 403 is installed at one end of the connecting box 401. The output end of the first stepper motor 403 is fixedly connected to one end of the bidirectional screw 402. The two sides of the inner wall of the connecting box 401 are respectively inserted and connected to the outer walls of the two moving blocks 404.

[0029] A rack 504 is fixedly provided on the other side of the fixed plate 501. A limiting slide 505 is fixedly provided at the bottom end of the rack 504. The limiting slide 505 is slidably connected to the limiting slide groove opened on the surface of the connecting box 401. The calibration mechanism 5 also includes two lugs 506. A gear 507 is rotatably connected between the two lugs 506. The gear 507 meshes with the rack 504. A switch panel is fixedly provided on one side of the handle 6. Two first step motor switches, two single-line laser light switches and a second step motor switch are fixedly provided on the surface of the switch panel. The two first step motors 403, the two single-line laser lights 503 and the second step motor 7 are electrically connected to an external power supply through the two first step motor switches, the two single-line laser light switches and the second step motor switch, respectively.

[0030] Working principle: When using this disassembly and assembly tool, the operator can turn on the linear laser light 503 in the alignment mechanism 5, push the rack 504, and the gear 507 on the support lug 506 will limit its movement. The limiting slide 505 on the rack 504 will slide in the limiting slide groove opened in the connecting box 401, thereby stabilizing the linear laser light 503 on the moving mounting base 502. The operator can then align the fixed position of the docking arm 407 and the gas-liquid connector. In the docking assembly 4, the first stepper motor 403 drives the bidirectional lead screw 402 to rotate, thereby causing the moving block 404 to move closer, allowing the upper docking arm 407 to be clamped and fixed first. The second stepper motor 7 on the drive frame 1 drives the drive lead screw 2. Then, the driving block 3 drives the lower docking component 4 to move. Similarly, the calibration mechanism 5 calibrates the lower fixed position and clamps it. After both docking components 4 are fixed, the driving block 3 moves down, which causes the lower docking component 4 to generate a downward force on the gas-liquid connector, so that it can be disassembled. If the docking arm 407 is to be replaced, the movable column 408 is pulled, and the retaining ring 411 acts on the connecting spring 412 to compress it, which in turn drives the locking part 410 to move up, so that it can be separated from the locking groove opened in the T-shaped docking block 406, and then the T-shaped docking block 406 is separated from the T-shaped docking groove 405 opened in the movable block 404, which is convenient for personnel to replace.
