Anti-collision quick-opening door structure for large geotechnical centrifuge

Abstract

The invention discloses an anti-collision door structure of a large geotechnical centrifuge. The anti-collision door structure is installed on the door opening channel of the cabin of the geotechnicalcentrifuge and comprises a buffer door mechanism and a side door mechanism; the buffer door mechanism comprises a sealing plate, bent anti-collision rods, an arc-shaped leveling plate and a levelingplate side face sealing plate; the middle parts of the sealing plate and the arc-shaped leveling plate are connected through a plurality of bent anti-collision rods; the side door mechanism comprisesa plurality of pin shafts; the pin shafts are supported by guide bearings; the guide bearings are installed through H-shaped steel; the middle pin shafts extend towards the middle of a side door shelland are machined into worms; the worms on two sides are connected through a worm wheel; a motor works to drive the worm wheel to rotate; and the worms on two sides are driven to horizontally and axially move through a worm wheel and worm pair; and all the pin shafts synchronously advance and retract and are inserted into pin shaft incoming holes. With the anti-collision door structure of the large geotechnical centrifuge adopted, energy absorption and collision prevention can be effectively achieved when the geotechnical centrifuge is impacted due to accidents; the geotechnical centrifuge will not be affected by the external environment and personnel; and test safety is guaranteed.

Description

technical field [0001] The invention relates to an anti-collision quick-opening structure, in particular to an anti-collision quick-opening structure for a vacuum cabin of a large geotechnical centrifuge. Background technique [0002] The large-diameter, high-acceleration, high-gravity geotechnical centrifuge is an indispensable device for the reproduction test of geological evolution processes such as rock-soil evolution, geological structure evolution, and geological disaster restoration. As the supergravity acceleration of the geotechnical centrifuge becomes higher and higher, the windage power increases at the third power, so it is very urgent to reduce the windage power. At present, the most effective way is to evacuate the cavity of the centrifugal chamber of the geotechnical centrifuge, and then the vacuum system will put forward new requirements for the design of the centrifugal chamber cavity of the geotechnical centrifuge, such as the anti-collision energy-absorbin...

Problems solved by technology

[0004] In order to overcome the problems existing in the background technical field, the object of the present invention is to provide a kind of large-scale geotechnical centrifuge vacuum chamber anti-collision, quick-opening door sealing structure, which adopts curved beams to absorb energy easily by elastic and plastic deformation under the action of large impact force, avoiding Difficulties with straight rods that transfer impact forces directly to rigid doors causing the entire door to fly out
