Problems solved by technology
Before the rocket is launched, it is necessary to contact the windproof compression device. At this time, the rocket has been filled with fuel. At this time, it is necessary to manually go up and operate to loosen the nut. There may be some fuel leakage and diffusion. The site environment is relatively harsh, and the operation requirements for personnel are relatively high.
Existing installations present safety hazards

The invention discloses an arrow foot support and an automatic windproof pressing device, which comprises a support arm structure, a manual support plate, a windproof nut and an adjusting device, a windproof bolt, a deceleration motor, a windproof bolt baffle, a bolt, a pinion, a large gear, Shaft end baffles, bolts, flat keys, arrow feet, crowbars. Among them, the windproof nut and the adjustment device are composed of a windproof nut, a telescopic arm, a horizontal cylinder, a vertical cylinder and a telescopic cylinder. The manual support plate is connected with the support arm structure, the middle part of the windproof bolt is connected with the manual support plate, and the lower part of the windproof bolt is connected with the large gear. The large gear meshes with two small gears, the small gears are driven by a reduction motor, and the upper part of the windproof bolt fixes the arrow foot above the manual support plate.
Description
technical field [0001] The invention relates to the field of aerospace technology, in particular to an arrow foot support and automatic windproof pressing device. Background technique [0002] The traditional windproof clamping device of rocket arrow foot is to connect the arrow foot with the support arm on the launch platform through bolts, nuts or bolts and windproof pressure plate, so as to prevent the wind load from causing instability to the rocket body. The bolt or windproof pressure plate The connection and loosening need to be done manually. Before the rocket is launched, it is necessary to contact the windproof compression device. At this time, the rocket has been filled with fuel. At this time, it is necessary to manually go up and operate to loosen the nut. There may be some fuel leakage and diffusion. The site environment is relatively harsh, and the operation requirements for personnel are relatively high. . The existing device has potential safety hazards. ...
